Interactions: Pharmacological interactions: Concomitant medication with other anticholinergic medicinal products may result in more pronounced therapeutic and undesirable effects. Allow approximately one week after stopping treatment with Vesomni before commencing any anticholinergic therapy. The therapeutic effect of solifenacin may be reduced by concomitant administration of cholinergic receptor agonists. Pharmacokinetic interactions: Pharmacokinetic interactions involving the potential for other medicinal products to affect Vesomni exposures: InteractionswithCYP3A4andCYP2D6inhibitors:See Contraindications, Posology and administration and Special warnings and precautions above. Concomitant administration may lead to increased exposure to both solifenacin (ketoconazole 400 mg/day resulted in a 1.5-fold increase in Cmax and a 2.8-fold increase in AUC). and tamsulosin (ketoconazole 400 mg/day resulted in a 2.2-fold increase in Cmax and a 2.8-fold increase in AUC). Vesomni should be used with caution in combination with strong CYP3A4 inhibitors. Vesomni should not be given together with strong CYP3A4 inhibitors in patients who are also CYP2D6 poor metabolizer phenotype or who are using strong CYP2D6 inhibitors. See SPC for details of the effects of other CYP3A4 and CYP2D6 inhibitors. Inducers: Inducers of CYP3A4 (e.g. rifampicin) may decrease the plasma concentrations of solifenacin and tamsulosin. Information available for the individual active substances Solifenacin can reduce the effect of medicinal products that stimulate the motility of the gastrointestinal tract, such as metoclopramide and cisapride. Solifenacin did not affect the pharmacokinetics of digoxin, or the pharmacokinetics or effect on prothrombin time of R- or S-warfarin. Co-administration of tamsulosin and other alpha1-adrenoreceptor antagonists could lead to hypotensive effects. Diclofenac and warfarin may increase the elimination rate of tamsulosin. No interactions have been seen when tamsulosin was given concurrently with atenolol, enalapril or theophylline. Fertility, pregnancy and lactation: The effect of Vesomni on fertility has not been established. Ejaculation disorders have been observed in short and long term clinical studies with tamsulosin. Events of ejaculation disorder, retrograde ejaculation and ejaculation failure have been reported in the post authorization phase. Vesomni is not indicated for use in women. Driving and use of machines: No studies have been performed, however patients should be informed about the possible occurrence of dizziness, blurred vision, fatigue and uncommonly somnolence, which may negatively affect the ability to drive or use machines. Undesirable Effects: Summary of the safety profile: Vesomni may cause anticholinergic undesirable effects of, in general, mild to moderate severity. The most frequently reported adverse reactions during the clinical studies performed for the development of Vesomni were dry mouth (9.5%), followed by constipation (3.2%) and dyspepsia (including abdominal pain; 2.4%). Other common undesirable effects are dizziness (including vertigo; 1.4%), vision blurred (1.2%), fatigue (1.2%), and ejaculation disorder (including retrograde ejaculation; 1.5%). Acute urinary retention (0.3%, uncommon) is the most serious adverse drug reaction that has been observed during treatment with Vesomni in clinical studies. List of adverse reactions: the ‘Vesomni frequency’ below reflects adverse drug reactions that have been observed during the double-blind clinical studies performed for the development of Vesomni (based on reports of treatment-related adverse events, which have been reported by at least two patients and occurred with a frequency higher than for placebo in the double-blind studies). The ‘solifenacin frequency’ and ‘tamsulosin frequency’ below reflect adverse drug reactions (ADRs) previously reported with one of the individual components (as presented in the Summary of Product Characteristics (SmPCs) of solifenacin 5 and 10 mg and tamsulosin 0.4 mg respectively that may also occur when receiving Vesomni (some of these have not been observed during the clinical development program of Vesomni). The frequency of adverse reactions is defined as follows: very common (≥1/10); common (≥1/100 to <1/10); uncommon (≥1/1,000 to <1/100); rare (≥1/10,000 to <1/1,000); very rare (<1/10,000), not known (cannot be estimated from the available data). The adverse events are grouped by MedDRA system organ class preferred term (PT).

Abbreviated Prescribing Information - Vesomni 6 mg/0.4 mg modified release tablets. Please read the Summary of Product Characteristics (SPC) before prescribing. Presentation: Each tablet contains a layer of 6 mg solifenacin succinate, corresponding to 4.5 mg solifenacin free base and a layer of 0.4 mg tamsulosin hydrochloride, corresponding to 0.37 mg of tamsulosin free base. Indication: Treatment of moderate to severe storage symptoms (urgency, increased micturition frequency) and voiding symptoms associated with benign prostatic hyperplasia (BPH) in men who are not adequately responding to treatment with monotherapy. Posology and method of administration: Adultmales,includingolderpeople: One Vesomni tablet (6 mg/0.4 mg) once daily taken orally with or without food. The maximum daily dose is one Vesomni tablet. The tablet must be swallowed whole, intact without biting or chewing. Do not crush the tablet. Special populations (see also contraindications below): Renal impairment: Severe renal impairment (creatinine clearance ≤ 30 mL/min): Treat with caution, maximum daily dose in these patients is one Vesomni tablet. Hepatic impairment: Moderate hepatic impairment (Child-Pugh score of 7-9): Treat with caution, maximum daily dose in these patients is one Vesomni tablet. In patients with severe hepatic impairment (Child-Pugh score > 9), the use of Vesomni is contraindicated. Concomitant treatment withmoderateandstronginhibitorsofCYP4503A4: e.g. verapamil, ketoconazole, ritonavir, nelfinavir, itraconazole: Treat with caution, maximum daily dose should be limited to one Vesomni tablet. Paediatricpopulation:There is no relevant indication for use of Vesomni in children and adolescents. Contraindications: Patients with hypersensitivy to the active substance(s) or to any of the excipients (see SPC). Patients undergoing haemodialysis. Patients with severe hepatic impairment. Patients with severe renal impairment who are also treated with a strong cytochrome P450 (CYP)3A4 inhibitor e.g. ketoconazole. Patients with moderate hepatic impairment who are also treated with a strong CYP3A4 inhibitor e.g. ketoconazole. Patients with severe gastrointestinal conditions (including toxic megacolon), myasthenia gravis or narrow-angle glaucoma and patients at risk for these conditions. Patients with a history of orthostatic hypotension. Special Warnings and Precautions for Use: Vesomni should be used with caution in patients with: severe renal impairment; risk of urinary retention; gastrointestinal obstructive disorders; risk of decreased gastrointestinal motility; hiatus hernia/ gastroesophageal reflux and/or who are concurrently taking medicinal products (such as bisphosphonates) that can cause or exacerbate oesophagitis; autonomic neuropathy. The patient should be examined in order to exclude the presence of other conditions, which can cause similar symptoms to benign prostatic hyperplasia. Other causes of frequent urination (heart failure or renal disease) should be assessed before treatment with Vesomni is initiated. If a urinary tract infection is present, appropriate antibacterial therapy should be started. QT prolongation and Torsade de Pointes have been observed in patients with risk factors, such as pre-existing long QT syndrome and hypokalaemia, who are treated with solifenacin succinate. Angioedema with airway obstruction has been reported in some patients on solifenacin succinate and tamsulosin. If angioedema occurs, Vesomni should be discontinued and not restarted. Appropriate therapy and/or measures should be taken. Anaphylactic reaction has been reported in some patients treated with solifenacin succinate. In patients who develop anaphylactic reactions, Vesomni should be discontinued and appropriate therapy and/or measures should be taken. As with other alpha1-adrenoceptor antagonists, a reduction in blood pressure can occur in individual cases during treatment with tamsulosin, as a result of which, rarely, syncope can occur. Patients starting treatment with Vesomni should be cautioned to sit or lie down at the first signs of orthostatic hypotension (dizziness, weakness) until the symptoms have disappeared. The ‘Intraoperative Floppy Iris Syndrome’ (IFIS, a variant of small pupil syndrome) has been observed during cataract and glaucoma surgery in some patients on or previously treated with tamsulosin hydrochloride. IFIS may increase the risk of eye complications during and after the operation. Therefore, the initiation of therapy with Vesomni in patients for whom cataract or glaucoma surgery is scheduled is not recommended. Discontinuing treatment with Vesomni 1-2 weeks prior to cataract or glaucoma surgery is anecdotally considered helpful, but the benefit of treatment discontinuation has not been established. During pre-operative assessment, surgeons and ophthalmic teams should consider whether patients scheduled for cataract or glaucoma surgery are being or have been treated with Vesomni in order to ensure that appropriate measures will be in place to manage IFIS during surgery. Vesomni should be used with caution in combination with moderate and strong inhibitors of CYP3A4 and it should not be used in combination with strong inhibitors of CYP3A4, e.g., ketoconazole, in patients who are of the CYP2D6 poor metaboliser phenotype or who are using strong inhibitors of CYP2D6, e.g., paroxetine.
Description of selected adverse reactions: For urinary retention see Special warnings and precautions for use. Older people: The therapeutic indication of Vesomni, moderate to severe storage symptoms (urgency, increased micturition frequency) and voiding symptoms associated with BPH, is a disease affecting elderly men. The clinical development of Vesomni has been performed in patients 45 to 91 years of age, with an average age of 65 years. Adverse reactions in the elderly population were similar to the younger population. Reporting of suspected adverse reactions: see below. Overdose: Overdosage with the combination of solifenacin and tamsulosin can potentially result in severe anticholinergic effects plus acute hypotension. Refer to SPC for details of treatment of overdose. Legal Category: Prescription Only Medicine (SIB). Nature and contents of container: Aluminium blister packs containing 30 tablets.

Hospital pharmacists that attended the launch, learned that there is no European definition for hazardous medicinal products and no clear European-wide guidance on their management. They exchanged with Joan Peppard and Falko Schüllner, who presented the SIG results, on the high awareness across EAHP’s member countries about hazardous medicinal products and the significant efforts that were made at an institutional level into the management of hazardous medicinal products thanks to the work of pharmacists over the years. However, despite these efforts, both speakers stressed at the launch that there remains an exposure risk to healthcare workers and caregivers that needs to be addressed.
As talks on Consultant contracts continue to stall in the absence of a new Independent Chair, the IHCA has renewed its call on Government to effectively address the record hospital waiting lists by ending the pay discrimination introduced in 2012 against Consultants contracted after that date.

two months into 2022 and instead of an expected reduction of around 22,000 people, the latest NTPF figures released today confirm that 12,800 additional people have in fact been added to these three main waiting lists since the start of the year - a 34,800 shortfall.

In one of our leading news stories this month, we reveal how the Government’s Waiting List Action Plan launched just some weeks ago has fallen at the first hurdle. The latest figures from the National Treatment Purchase Fund (NTPF) show increases rather than reductions in the number of people waiting for care.
Inspired by a project carried out in Belgium and Luxembourg evaluating the effectiveness of the electronic patient information leaflet and the key principles created by the European Medicines Agency (EMA) and the Heads of Medicines Agencies (HMA), the European Association of Hospital Pharmacists (EAHP) conducted a survey on the use of electronic product information (ePI) in European hospitals.

The World Health Organization (WHO) recently released an Implementation handbook for national action plans on AMR that provides guidance for the human health sector. This publication aims on the one hand at providing a practical, stepwise approach to national action plan implementation within the human health sector. On the other hand, it offers a process and a collation of WHO tools to prioritise, implement, monitor and evaluate national action plan activities.
This publication links to the endorsement of the Global action plan on antimicrobial resistance (AMR) at the World Health Assembly in 2015 that calls on countries to develop and implement national action plans on AMR. The development itself does not pose the biggest challenge, but countries seem to struggle with the implementation of the plan based on evidence-based prioritization of activities, systematic monitoring of progress, and ensuring the sustainability of efforts. The implementation handbook seeks to address this.
The target audience of the publication includes national/subnational stakeholders working on AMR within the human health sector. This includes national health authorities, national multi-sectoral coordination groups, senior technical experts and policymakers involved in implementing AMR activities at all levels of the health system, and implementation partners to accelerate sustainable implementation and monitoring and evaluation of national action plans on AMR.

two years of the pandemic, and is clear also in the context of the devastating conflict in Ukraine, is that EMA must remain agile, responsive and ready to show leadership and solidarity in light of significant developments in the environment in which it operates.”, said Dr Nolan. “As chair, my focus will be to continue and further enhance the strong partnership between EMA, national agencies and the European Commission. Collectively, we must ensure that EMA continues to deliver the highest standards of public and animal health protection while maintaining its global reputation as a modern, progressive and transparent regulator”.
The survey reveals that patients are usually not provided with paper package leaflets and only 21% of respondents reported that medicines information is provided orally to patients. In this regard, the majority of respondents see the potential of further informing patients by giving them access to ePI. It would also ensure that the information accessed is up to date.

Reflecting on the process and the results of the survey, former EAHP Board member Steffen Amann, who was involved in the project from the start, highlighted that “Digitalisation is revolutionising healthcare provision in hospitals across Europe. For EAHP it was consequently very important to learn more about the use of electronic patient leaflets and the future potential of electronic product information. It will take a lot of activity to overcome the lack of means to work with digital information, which not surprisingly is one of the main barriers for the use of ePI in hospitals.”

Outpatient waiting lists alone have increased by 68,000 (12%) since 2020, with the number of those waiting to be assessed by a Consultant almost doubling to 626,658 in the past eight years – a 94% (+303,000)
the IHCA has renewed its call on Government to effectively address the record hospital waiting lists by ending the pay discrimination introduced in 2012 against Consultants contracted after that date. Consultants say this is a critical step towards re-establishing trust and making Ireland a more competitive market for highly skilled medical and surgical specialists.
have raised concerns that outpatient waiting lists will need to decrease by an average of 13,900 per month between now and the end of 2022 if the overall Waiting List Action Plan target of reducing the number awaiting an outpatient appointment to 487,000 is to be achieved.
12,800 additional people have in fact been added to these three main waiting lists since the start of the year - a 34,800 shortfall.**
two months into 2022 and instead of an expected reduction of around 22,000 people, the latest NTPF figures released today confirm that
IHCA President Professor Alan Irvine, said, “Solutions cannot emerge from a vacuum or by skirting around the clear and sustainable actions. This approach over the last decade has severely undermined trust and is driving our highly trained medical and surgical specialists abroad, leaving our patients without access to the care they need and deserve.”
The warning from Consultants over the Government and HSE’s unrealistic waiting list targets
The Irish Hospital Consultants Association (IHCA) has warned that the Government’s Waiting List Action Plan launched just three weeks ago has fallen at the first hurdle, with the latest figures from the National Treatment Purchase Fund (NTPF) showing increases rather than reductions in the number of people waiting for care.

Over four in five people, or 84%, trust the medical evidence on vaccines. ‘Vaccine believers’people who think vaccines are effective and trust the medical evidence - have increased by 11 points since a similar poll was taken in late 2019.
More than 770 students took part in White Coat Ceremonies at RCSI University of Medicine and Health Sciences recently.
Four in five people, or 80%, believe there is misinformation about vaccines - up 15 points since shortly before the pandemic. Almost one-third of people, or 31%, believe there isn’t enough information available about vaccines. Women and younger people are more likely than men and older age cohorts to seek information about vaccines, according to the survey.

The Irish Hospital Consultants Association (IHCA) has today (21 March 2022) said that this latest vacancy data is a cause for serious concern, amid worries of the impact of Consultant staffing shortages on the delivery of health services and the quality of patient care.
Dr Denis O’Keeffe, Consultant Haematologist and Director of Cancer Services for UL Hospitals Group, said, “We are delighted to see this project being opened in University hospital Limerick. The early detection of lymphoedema in high risk patients will provide the opportunity to treat and prevent more serious long term issues. It will also provide great support for patients who develop this very difficult and often challenging complication.”

products metabolized by CYP2D6 with a narrow therapeutic index such as thioridazine, Type 1C antiarrhythmics (e.g.flecainide, propafenone) and tricyclic antidepressants (e.g., imipramine, desipramine). Caution is also advised if mirabegron is co-administered with CYP2D6 substrates that are individually dose titrated. Inhibition of P-gp: Mirabegron is a weak inhibitor of P-gp. For patients who are initiating a combination of Betmiga and digoxin, the lowest dose for digoxin should be prescribed initially. Serum digoxin concentrations should be monitored and used for titration of the digoxin dose to obtain the desired clinical effect. The potential for inhibition of P-gp by mirabegron should be considered when Betmiga is combined with sensitive P-gp substrates e.g. dabigatran. Fertility, pregnancy and lactation: The effect of mirabegron on human fertility has not been established. Betmiga is not recommended during pregnancy and in women of child-bearing potential not using contraception. Mirabegron should not be administered during breast feeding. Refer to SPC for full guidance. Driving and use of machines: Betmiga has no or negligible influence on the ability to drive and use machines. Undesirable effects: Summary of the Safety Profile: the safety of Betmiga was evaluated in 8433 patients with OAB, of which 5648 received at least one dose of mirabegron in the phase 2/3 clinical program, and 622 patients received Betmiga for at least 1 year (365 days). In the three 12-week phase 3 double blind, placebo controlled studies, 88% of the patients completed treatment with this medicinal product, and 4% of the patients discontinued due to adverse events. Most adverse reactions were mild to moderate in severity. The most common adverse reactions reported for patients treated with Betmiga 50 mg during the three 12-week phase 3 double blind, placebo controlled studies are tachycardia and urinary tract infections. The frequency of tachycardia was 1.2% in patients receiving Betmiga 50 mg. Tachycardia led to discontinuation in 0.1% patients receiving Betmiga 50 mg. The frequency of urinary tract infections was 2.9% in patients receiving Betmiga 50 mg. Urinary tract infections led to discontinuation in none of the patients receiving Betmiga 50 mg. Serious adverse reactions included atrial fibrillation (0.2%). Adverse reactions observed during the 1-year (long term) active controlled (muscarinic antagonist) study were similar in type and severity to those observed in the three 12-week phase 3 double blind, placebo controlled studies. The following adverse reactions were observed with mirabegron in the three 12-week phase 3 double blind, placebo controlled studies. The frequency of adverse reactions is defined as follows: very common (≥1/10); common (≥1/100 to <1/10); uncommon (≥1/1,000 to <1/100); rare (≥1/10,000 to <1/1,000); very rare (<1/10,000); not known (cannot be established from the available data) Within each frequency grouping, adverse reactions are presented in order of decreasing seriousness. The adverse events
strong CYP3A inhibitors. Hypertension: Mirabegron can increase blood pressure. Blood pressure should be measured at baseline and periodically during treatment with mirabegron, especially in hypertensive patients. Data are limited in patients with stage 2 hypertension (systolic blood pressure ≥ 160 mm Hg or diastolic blood pressure ≥ 100 mm Hg). Patients with congenital or acquired QT prolongation: Betmiga, at therapeutic doses, has not demonstrated clinically relevant QT prolongation in clinical studies. However, since patients with a known history of QT prolongation or patients who are taking medicinal products known to prolong the QT interval were not included in these studies, the effects of mirabegron in these patients is unknown. Caution should be exercised when administering mirabegron in these patients. Patients with bladder outlet obstruction and patients taking antimuscarinic medicinal products for OAB: Urinary retention in patients with bladder outlet obstruction (BOO) and in patients taking antimuscarinic medicinal products for the treatment of OAB has been reported in postmarketing experience in patients taking mirabegron. A controlled clinical safety study in patients with BOO did not demonstrate increased urinary retention in patients treated with Betmiga; however, Betmiga should be administered with caution to patients with clinically significant BOO. Betmiga should also be administered with caution to patients taking antimuscarinic medicinal products for the treatment of OAB. Interactions: Pharmacokinetic interactions: Mirabegron is a substrate for CYP3A4, CYP2D6, butyrylcholinesterase, uridine diphosphoglucuronosyltransferases (UGT), the efflux transporter P-glycoprotein (P-gp) and the influx organic cation transporters (OCT) OCT1, OCT2, and OCT3. Pharmacokinetic interactions involving the potential for other medicinal products to affect mirabegron exposures: Increases in mirabegron exposure due to drug-drug interactions may be associated with increases in pulse rate. Strong CYP3A inhibitors See Posology and administration above for dose adjustments recommended during concomitant use of strong CYP3A inhibitors in patients with renal or hepatic impairment. Mirabegron exposure (AUC) was increased 1.8-fold in the presence of the strong inhibitor of CYP3A/P-gp ketoconazole. CYP2D6 inhibitors: No dose adjustment is needed for mirabegron when administered with CYP2D6 inhibitors (or in patients who are CYP2D6 poor metabolisers). Inducers: Inducers of CYP3A (such as rifampicin) or P-gp may decrease the plasma concentrations of mirabegron. No dose adjustment of mirabegron is required as this effect is not expected to be clinically relevant. Pharmacokinetic interactions involving the potential for mirabegron to affect exposures to other medicinal products: Inhibition of CYP2D6: Moderate and time dependent inhibition of CYP2D6 by mirabegron may result in clinically relevant drug interactions. CYP2D6 activity recovers within 15 days after discontinuation of mirabegron. Caution is advised if mirabegron is co-administered with medicinal

A lower dose of 25mg is recommended for specific patient populations (renal and hepatic impairment) as well as in specific patient populations in combination with strong CYP3A inhibitors such as itraconazole, ketoconazole, ritonavir and clarithromycin. Renal impairment: End stage renal disease (GFR < 15 mL/min/1.73 m2 or patients requiring haemodialysis): Not recommended. Severe renal impairment (GFR 15 to 29 mL/min/1.73 m2): Reduce dose to 25 mg. Severe renal impairment and concomitant strong CYP3A inhibitors: Not recommended. Moderate renal impairment (GFR 30 to 59 mL/min/1.73 m2): 50 mg. Moderate renal impairment and concomitant strong CYP3A inhibitors: Reduce dose to 25 mg. Mild renal impairment (GFR 60 to 89 mL/min/1.73 m2): 50 mg. Mild renal impairment and concomitant strong CYP3A inhibitors: Reduce dose to 25 mg. Hepatic impairment: Severe hepatic impairment (Child-Pugh Class C): Not recommended. Moderate hepatic impairment (Child-Pugh B): Reduce dose to 25 mg. Moderate hepatic impairment and concomitant strong CYP3A inhibitors: Not recommended. Mild hepatic impairment (Child-Pugh A): 50 mg. Mild hepatic impairment and concomitant strong CYP3A inhibitors: Reduce dose to 25 mg. The tablet is to be taken once daily, with liquids, swallowed whole and is not to be chewed, divided, or crushed. It may be taken with or without food Contraindications: Hypersensitivity to the active substance or to any of the excipients (see the SPC for a list of excipients). Severe uncontrolled hypertension defined as systolic blood pressure ≥180 mm Hg and/or diastolic blood pressure ≥110 mm Hg. Special warnings and precautions for use: Renal impairment: Betmiga has not been studied in patients with end stage renal disease (GFR < 15 mL/min/1.73 m2 or patients requiring haemodialysis) and, therefore, it is not recommended for use in this patient population. Data are limited in patients with severe renal impairment (GFR 15 to 29 mL/min/1.73 m2); based on a pharmacokinetic study a dose reduction to 25 mg is recommended in this population. This medicinal product is not recommended for use in patients with severe renal impairment (GFR 15 to 29 mL/min/1.73 m2) concomitantly receiving strong CYP3A inhibitors. Hepatic impairment: Betmiga has not been studied in patients with severe hepatic impairment (Child-Pugh Class C) and, therefore, it is not recommended for use in this patient population. This medicinal product is not recommended for use in patients with moderate hepatic impairment (Child-Pugh B) concomitantly receiving

The Centre for Personalised Medicine, Clinical Decision Making, and Patient Safety (CPM) focuses on five disease areas, which are: emergency surgery, acute kidney injury, cardiovascular disease, diabetes, and dementia.
Essentially these are relative to concerns around training, workforce, and operational issues. These are central to variations in the outcomes that have been identified across EGS and have been amplified by both the Health Service Executive/Royal College of Surgeons in Ireland and the Nuffield Trust/Royal College of Surgeons of England.
Cross-border Centre for Personalised Medicine Emergency General Surgery Cluster Creates a new concept in the treatment of Emergency Surgery Patients
The Emergency Surgery Outcome Advancement Project (eSOAP) was funded by the EU’s INTERREG VA Programme, which is managed by the Special EU Programmes Body (SEUPB).

The Centre for Personalised Medicine’s, Emergency Surgery Research cluster was formed following almost 10 years of planning between Letterkenny University Hospital, Ulster University, Western Health and Social Care Trust, working with partners in the Letterkenny Institute of Technology, University of the Highlands and Islands, NHS Scotland, Randox Laboratories and Randox Teoranta, United Health Group / Optum, Clinishare Ltd., Health Analytics Ltd., Northern Ireland Clinical Research Services, National University of Ireland Galway, Donegal Clinical Research Academy, Clinical Translational Research and Innovation Centre
A new report was launched last month entitled ‘Emergency General Surgery Report Improving Outcomes and Saving Lives.’ It was launched by the Emergency General Surgery consortium.
The Emergency Surgery Outcomes Advancement Project (eSOAP) commenced during late 2018 and is situated within the CPM.
It has been reported previously that EGS, and its associated burden, accounts for more than half of the surgical workload across the UK National Health Service (NHS) and half of all surgical mortality within the United States. This is compounded by an inefficient triage of patients presenting with abdominal pain, wide variability in diagnostic pathology testing
This situation has been further aggravated by the Covid-19 crisis during 2020/2021. Within the context of EGS care in Ireland, in 2014 50% of all general surgical activity nationally (Table 1) occurred in Model 3 Hospitals.

Professor Bill Schwab, from the University of Pennsylvania (USA), considered an expert in emergency medical, surgical and trauma systems said “…the recommendations of this report, when implemented, would have far reaching effects by improving the quality and efficiency of care and outcomes of patients across Ireland, Northern Ireland and ProfessorScotland.”Ravi Vorha, a world expert in Emergency Surgery systems delivered a keynote address at Derry City Hotel at the closing conference of the Centre of Personalised Medicine Conference on March 23rd and said he felt that “the work done by the EGS Research Cluster and their achievements have created a platform to vastly improve care of emergency patients. The implications of this research could positively affect the health of over 2 million annual admissions in the EU.”
performance and key outcome analysis in patients care and was a remarkable achievement.’
Ireland, and the United States provide a contextual backdrop to the ongoing challenges and limitations across the scope of EGS. These reports have emphasised the need for improvements in the delivery of the quality and safety of EGS care whilst outlining possible mechanisms through which this transformation can be achieved. They also refer to the overriding need to enhance the patient experience of EGS care.
The collaborative interregional research team’s research is an innovative approach to Emergency General Surgery Care (EGS). EGS patients account
for 10% of emergency hospital admission world-wide with over 150,000 hospital admission annually in the island of Ireland and two million in the EU.
The 350 page document reports some unique achievements, which if implemented in the EU could reduce mortality in critically ill emergency surgery patients resulting in over 20,000 lives being potentially saving and reducing complications.

Innovative Approaches
Mr Michael Sugrue, Surgeon at Letterkenny University Hospital and project lead, said the team created a unique data registry, combined with new contemporary clinical pathways and analysis of delivery of care to over 6000 patients. Mr Sugrue said the team worked to develop new key outcome indicators in surgery, the first such performance indicators assessed in this patient population in Europe.

Mr Michael Sugrue said focusing on clinical care is crucial for patients with emergency general surgery conditions such as appendicitis, acute inflammation of the gallbladder or bowel problems. He said “key outcome and performance indicators provide a template to set new benchmarks in surgical care”. Mr. Sugrue has made a call for the government to act on the implementation of the recommendations in this report.

The organisation said in a statement, “A world where everyone benefits from access to safe, effective, quality and affordable medicines and health technologies, as well as from pharmaceutical care services provided by pharmacists, in collaboration with other healthcare professionals is the vision that FIP is working towards. FIP condemns all acts of violence or war causing suffering, and has long supported the pharmacy profession in humanitarian work.
While Ireland is a global leader in the pharmaceutical industry, patient access to medicines is somewhat limited. According to Thorsten Giesecke General Manager Commercial Business at Janssen Sciences Ireland, “Studies have shown 35% of medicines licensed in Europe, most of which are made in Ireland, are available to patients in Ireland. This is an opportunity where if Government looks at the industry holistically to include manufacturing, clinical research and the domestic health service, they can drive this eco-system.”
“As healthcare professionals, pharmacists have an ethical duty and responsibility of providing aid to others in disaster situations. We remind all our members and others of our Statement of Policy on the role of the pharmacist in the management of disasters, be they natural or man-made, war, civil disorder or pandemics.

is known as a ‘cognitive overload’ and they experience a subjective experience of fatigue.
The quote above is one that resonates a lot with me - and should to most healthcare workers. The past two years (and many years before that) have been challenging, and the above and beyond has been expected on a daily basis. It can often seem like the system is broken and beyond repair - leaving many feeling helpless. I hope my insights can share a small bit of light into helping you with your health and wellbeing over the coming months.
I’m delighted to be joining as a regular contributor to discuss all things related to fatigue, burnout, sleep and rest. My background is in physiotherapy and I recently completed my PhD in the behavioural sciences exploring how issues related to fatigue can manifest themselves in healthcare workers. I also explored how we can begin to resolve some of those modifiable aspects of our day-today lives, as well as the systems we work in to make ourselves feel better and perform better.

In this piece, I will outline some of the main theories around fatigue management in the workplace and offer a practical set of strategies for you to use.
What does this mean for our performance in work?
So, what does that relationship tell us? First, it tells us how ‘goals’ can shape our experience of fatigue – so if we can make the tasks we are completing somewhat more goal-oriented,
In subsequent articles I'll be talking more in-depth about the complexity of these issues and hope to get your input, and input from other experts in the field, in designing solutions to make healthcare the people-centred sector it should be.

Historical views of fatigue management
When we talk about fatigue, cognitive load theory1 is often referenced. This theory suggests that as individuals we have a finite amount of information we can store in what is termed our ‘working memory’ at any given time. Working memory is the conscious experience of knowledge as experienced in real time. When individuals are overburdened with too much information, they experience what

rather be working on practicing an inservice you’re presenting at in the evening) or somatic goals (e.g., a need to sleep or eat). We typically push through the urge, employing a series of strategies to ‘concentrate’ on the task. In doing so, we continue to increase the level of fatigue we experience until eventually we enter a phase known as the ‘strain’ phase. In this instance, fatigue is high. Should we decide to pursue further, we will enter the ‘disengaged’ phase whereby there will be significant fatigue and after-effects, and associated decrement in performance.
While cognitive load is useful as a concept for thinking about fatigue, more recent research looks at issues around self-determination, motivation, and how the individual has a more influential role in the prevention and management of the fatigued state. Popularised in the 2010’s by a book called ‘The Psychology of Fatigue’2, motivation can be said to play a pivotal role in determining how an individual reacts to a work task. Let us take a work task like charting a patient’s medications as an example. This new theory suggests we can optimise our work in a more nuanced way. Using Figure 1, let us imagine we are ten minutes into designing the task and suddenly we begin to feel a small ‘urge’ of discomfort. This is the first emotional signal of the fatigue state. It tells you that your current task is not aligning with your desired goals, whether they be personal goals (e.g., you would

Fatigue is not necessarily a ‘good’ or ‘bad’ feeling. It simply is an emotional signal that tells us that current tasks are in contravention to desired goals. With that in mind, we should focus our efforts on making work-related tasks more goal-oriented and enjoyable; while also taking the time to pause when we experience fatigue and see if alternative activities need to be employed for longer term performance sustainability and optimal wellbeing. With that in mind, why not try and lean into recognising the onset of fatigue signals in your day-to-day life for the next few days. Identify the triggers that seem to exacerbate those signals and see if you can modify your workday to prevent the fatigue from increasing.

feeling of volition over your own actions and your behaviours), and relatedness (I.e., a sense of closeness to those around you)4. Fulfilling these needs in the workplace, through appropriate workload modelling (Figure 2) is important to maintain motivation in the workplace. Similarly, engaging in fulfilling and nourishing these needs in non-work settings is important in the prevention of longer-term fatigue related issues (e.g., burnout). Individuals can identify activities which promote a perceived sense of competency (I.e., learning a new skill), a sense

Secondly, it tells us the importance of addressing any other goals which are in conflict with our current task, even if it means taking a small amount of time away from the task at hand to address these goals. Third, it offers us a ‘signal’ that we can begin to use to raise levels of self-awareness and therefore avoid states of experiencing high fatigue on a regular basis. Finally, the theory provides us with an insight into the relationship between work and non-work activities. Should

the fact that some patients found paraesthesia was uncomfortable. The development of higherfrequency stimulation and removal of paraesthesia-based stimulation has made this treatment more acceptable to the majority of patients. Furthermore, the development of burst stimulation, which more closely mimics physiological neural function is improving efficacy.
There is growing evidence that CNP is initiated, maintained and recovered by changes in the neural proteome and cellular immune function. There is a growing body of clinical work that demonstrates spinal cord stimulation in vivo alters the proteome within the cerebrospinal fluid and t-cell phenotype. There is therefore growing information regarding how spinal cord stimulation works and this tends to support higher frequencies of stimulation. The mode of action of spinal cord stimulation has developed beyond the idea that the resultant electrical field caused the interneurons to modulate pain signaling in the dorsal columns – the gate theory of pain control. There is a growing body of clinical evidence which identifies that spinal cord stimulation can modulate peptides implicated in CNP pathophysiology in the
cerebrospinal fluid including VEG-F, IL-10, in addition to the cellular constituents including CD4/ CD8 ratios and glial cell activation favouring constituent relationships that promote recovery from chronic neuropathic pain.
Chronic neuropathic pain (CNP) is a specific form of chronic pain. It is caused by a dysfunction of the somatosensory nervous system. It affects approximately 8% of the population. In addition to trauma and stroke, a number of medical conditions contribute to activation of CNP including diabetes, multiple sclerosis, complications of common surgeries such as hernia repair, breast surgery, vasectomy and neurodegenerative disorders. It is associated with cancer chemotherapy also. This is a common and difficult problem to treat.

Other factors that promote spinal cord stimulation include the removal of the necessity of the “trial of stimulation,” in addition to the technical improvements.

usage and this required a further visit to the operating theatre. IPG replacement was usually performed in the daycare unit. Therefore, spinal cord stimulation was seen as extremely expensive and access to it was limited primarily by funding concerns. A significant expenditure both financially and in terms of the pain service time was required to employ the therapy for one patient. Other concerns expressed by funders related to lack of knowledge regarding how this system actually worked.
However, clinical researchers in this field over the last 15 years in particular have made significant improvements in our knowledge regarding the initiating, maintenance and recovery factors involved in the development of chronic neuropathic pain and also developed a greater understanding of the functioning of spinal cord stimulation in vivo. This has been married with successful technological developments over a similar time period.
It has been recognized that spinal cord stimulation in appropriately selected patients is more effective than pharmacological therapy and avoided the daily use of medication with associated compliance issues and development of tolerance and side-effects. However, spinal cord stimulation was initially very expensive with a significant workup preplacement, a requirement of two visits to the operating theatre with associated inpatient stay and significant complication rates. In addition to this, the most expensive component of the spinal cord stimulator, the implantable pulse generator (IPG) needed to be replaced every 3 to 5 years depending upon
There are now many more options in terms of programming the IPG which means the system is much more versatile. Traditionally lowfrequency stimulation was used which was paraesthesia-based. This has significant limitations and effectiveness in addition to

After a patient had been deemed suitable for spinal cord stimulation the traditional approach was that the patient underwent a trial whereby the electrode lead was inserted under sedation and connected to an externalized power source. The patient went home for a period of time which could range from 2 to 3 days to one month in some European countries. The rationale for trial was an attempt to prove the system would help the patient prior to implantation of the IPG which was the most expensive part of the system. However, it also opened up the possibility of infection due to the externalized lead and did not mimic accurately the situation of having an implanted stimulator. Numerous restrictions were required including being unable to shower or drive as well as appropriate attention being paid to this bulky system which meant that it did not accurately reflect an implanted system. There was no comprehensive evidence supporting this and recently the International Neuromodulatory Society has very much challenged this mandated approach. As always in medical practice, patient selection is absolutely crucial and this is more relevant than carrying out a trial. Today it is acceptable to proceed straight to implantation of the spinal-cord stimulator if the clinician deems this is the best treatment for a given patient. This change in practice has significant implications in terms of the cost of providing the service and potential complications by reducing the number of operating theatre visits from two to one. The

of dapagliflozin is recommended until volume depletion is corrected. Diabetic ketoacidosis (DKA): Rare cases of DKA, including life-threatening and fatal cases, have been reported in patients treated with SGLT2 inhibitors, including dapagliflozin. In a number of cases, the presentation of the condition was atypical with only moderately increased blood glucose values, below 14mmol/L (250mg/dL). The risk of DKA must be considered in the event of non-specific symptoms such as nausea, vomiting, anorexia, abdominal pain, excessive thirst, difficulty breathing, confusion, unusual fatigue or sleepiness. Patients should be assessed for ketoacidosis immediately if these symptoms occur, regardless of blood glucose level. In patients where DKA is suspected or diagnosed, dapagliflozin treatment should be stopped immediately. Treatment should be interrupted in patients who are hospitalised for major surgical procedures or acute serious medical illnesses. Monitoring of ketones is recommended in these patients. Measurement of blood ketone levels is preferred to urine. Treatment with dapagliflozin may be restarted when the ketone values are normal and the patient’s condition has stabilised. Before initiating dapagliflozin, factors in patient history that may predispose to ketoacidosis should be considered. Patients who may be at higher risk of DKA include patients with a low beta cell function reserve (e.g. patients with low C peptide or latent autoimmune diabetes in adults (LADA) or patients with a history of pancreatitis), patients with conditions that lead to restricted food intake or severe dehydration, patients for whom insulin doses are reduced and patients with increased insulin requirements due to acute medical illness, surgery or alcohol abuse. SGLT2 inhibitors should be used with caution in these patients. Restarting SGLT2 inhibitor treatment in patients experiencing a DKA while on SGLT2 inhibitor treatment is not recommended, unless another clear precipitating factor is identified and resolved. Dapagliflozin should not be used for treatment of patients with type 1 diabetes. Necrotising fasciitis of the perineum (Fournier’s gangrene): Postmarketing cases have been reported in female and male patients taking SGLT2 inhibitors. Urgent surgical intervention and antibiotic treatment is required. Advise patients to seek medical attention if they experience a combination of pain, tenderness, erythema, or swelling in the genital or perineal area, with fever or malaise. Either uro-genital infection or perineal abscess may precede necrotising fasciitis. If suspected, discontinue Forxiga and institute prompt treatment (including antibiotics and surgical debridement). Urinary tract infections: Temporary interruption of dapagliflozin should be considered when treating pyelonephritis or urosepsis. Elderly (≥65 years): Elderly patients are more likely to have impaired renal function, be treated with medicines such as anti-hypertensives or diuretics, and be at a greater risk of volume depletion. Cardiac failure: Experience with dapagliflozin in NYHA class IV is limited. Chronic kidney disease: There is no experience with dapagliflozin for the treatment of chronic kidney disease in patients without diabetes who do not have albuminuria. Patients with albuminuria may benefit more from treatment with dapagliflozin. Lower limb amputations: Counsel patients with diabetes on routine preventative foot care as an increase in cases of lower limb amputation (primarily of the toe) has been observed in long term, clinical studies in type 2 diabetes mellitus with SGLT2 inhibitors. Urine laboratory assessments: Patients will test positive for glucose in the urine due to mechanism of action. Lactose: Patients with rare hereditary problems of galactose intolerance, total lactase deficiency, or glucose-galactose malabsorption should not take Forxiga.
GFR
Warnings and Precautions: Renal impairment: Due to limited experience, it is not recommended to initiate treatment with dapagliflozin in patients with GFR < 25 mL/min. The glucose lowering efficacy of dapagliflozin is dependent on renal function, and is reduced in patients with GFR < 45 mL/min and is likely absent in patients with severe renal impairment. Hepatic impairment: Exposure is increased in patients with severe hepatic impairment. Use in patients at risk of volume depletion and/or hypotension: Dapagliflozin increases diuresis which may lead to a modest decrease in blood pressure, it may be more pronounced in patients with very high blood glucose concentrations. Exercise caution in patients for whom a dapagliflozin induced drop in blood pressure could pose a risk, such as patients on anti hypertensive therapy with a history of hypotension or elderly patients. Careful monitoring of volume status and electrolytes is recommended in conditions leading to volume depletion, such as acute gastrointestinal illness. In volume depleted patients temporary interruption

The situation could arise whereby the chronic neuropathic pain complaint had improved however the patient was now experiencing a surgical issue which was pouch pain.

Spinal cord stimulation has developed into a much more effective, affordable and userfriendly therapy. Traditionally funding bodies expressed serious concerns about the cost of this therapy for one patient who had a disease that was not seen as life-threatening. The new developments in terms of removal of the mandate to trial, the smaller IPG with a much longer lifespan requiring fewer replacements and reduction in complication rates make spinal-cord stimulation more affordable. The advent of new programming paradigms has made the system more effective. Therefore, the future for spinal cord stimulation is bright.

When undetected and untreated, AF in some patients can lead to potential complications including stroke or heart failure. Furthermore, AF is associated with a small reduction in longevity and an associated increased incidence of dementia.

“The HPRA has over many years identified that a significant proportion of detained products are falsely labelled, do not contain accurate information on the strength of active ingredient they contain, or have been found to contain a different ingredient altogether. When you consider also that these products are often delivered without a leaflet, instructions for use or information on the correct dose, the illegal supply of unregulated and potentially fake medicines clearly presents a significant risk to public health,” says Ms Power.

Catheter ablation of atrial fibrillation works best in patients with early disease and is more effective in patients with paroxysmal AF and is considerably less effective in patients with long-standing persistent AF.
“With all the indicators suggesting that the number of people who develop AF will increase significantly in coming years, Irish patients need to know that the best possible care is available to them.
A sub-analysis of the largest randomised trial of AF ablation indicated no prognostic benefit of AF ablation in patients over 75 years of age and in this older cohort the only indication for ablation would be for the relief of symptoms not relieved by medication.

that over 3.2 million units were detained over a two-year period.
Conventional catheter ablation of AF is achieved by thermal (radiofrequency) or cryothermal energy. Cryo-balloons have been used for many years, and can achieve low temperatures in the heart muscle and isolate the pulmonary veins.
Atrial fibrillation, or AF, is an irregular and often rapid heart rhythm, and it is the most common sustained cardiac arrhythmia with a growing prevalence.
A key component of catheter ablation of AF is electrical isolation of the pulmonary veins from the left atrium.
Professor Keane and the team at Blackrock Clinic carried out the first procedure using iCLAS in February, and the hospital’s CEO James O’Donoghue said that this demonstrated Blackrock’s ongoing commitment to making industry-leading technology available to Irish patients at the earliest opportunity.
• 5 prosecution cases initiated, and seven voluntary formal cautions issued
Recently, a novel technology has been developed to achieve much lower temperatures (well below minus 120°C) in the targeted heart muscle to achieve pulmonary vein isolation.
Professor David Keane, director of the cardiac electrophysiology service at the Blackrock Clinic, said that the advantages of the novel system include the efficiency of the ultra-cold ablation system, the flexibility and subsequent conformability of the curvilinear ablation element to adopt to the patient’s atrial anatomy, as well as the incorporation of a warming balloon to protect the oesophagus.

Caring for Women with Epilepsy in Pharmacy
Dr Nicola Maher has a special interest in medical conditions in pregnancy and in particular epilepsy. Together with Sinead Murphy Advanced Nurse Practitioner in Epilepsy they run a dedicated antenatal service for women with epilepsy. Patients are seen throughout their pregnancy and preconceptual counselling is also provided. Dr Maher also is a member of the Irish Medicines in Pregnancy Service (IMPS), a multidisciplinary service based at the Rotunda Hospital which provides information and expertise to support safe and effective use of medicines before, during and after pregnancy.

doses. As a general rule, if a woman vomits within one hour of taking her anti-seizure medications a second dose can be taken. If persistent vomiting is a problem, women should see their GP or visit their obstetric caregiver. Effective antiemetics are essential in managing hyperemesis in pregnancy which can affect up to 3% of all pregnant women.
There is not enough data to confirm or rule out any additional risks in pregnancy in women taking the above medication. These are second line agents often used where other treatments have been unsuccessful in controlling seizures. Studies are ongoing to evaluate their safety profile in pregnancy. The absence of this data does not equate to known harm for the fetus and again women should be advised not to stop their medication without consulting with their doctor.
Carbamazepine is a very effective anti-seizure medication. Many women who take carbamazepine have very well controlled epilepsy for years. Carbamazepine confers a small additional risk to the fetus in pregnancy. The congenital anomaly rate associated with Carbamazepine use in pregnancy is 4-5%. Similarly Topiramate which is less commonly prescribed for epilepsy confers a risk of approximately 6% of congenital abnormality. Women being prescribed these medications would especially benefit from preconceptual consultations with their neurologist and obstetrician. Individualised risk benefit discussions can be made to discuss medication best suited to the woman to optimise seizure control, while minimising risks of congenital anomaly. Phenytoin, less commonly prescribed is associated with a 6% risk of congenital anomaly. Studies in relation to developmental delay with these medication are contradictory and a risk cannot be excluded.

All women planning a pregnancy should be offered preconceptual counselling with their neurology service and an obstetrician. This affords the opportunity to review medications and assess seizure history as well as perform serum drug levels if needed.

Thankfully pregnancy for most women with epilepsy remains uncomplicated and they are not at increased risk of any obstetric complications of pregnancy. Maintaining seizure control while providing up to date information on medication safety profiles are key to the care of women with epilepsy in pregnancy.
Physiologic and pharmacokinetics changes in pregnancy (e.g. increased volume of distribution, changes to renal elimination, altered hepatic enzymes) may alter serum plasma levels of antiseizure medication in pregnancy. Lamotrigine and Levetiracetam are particularly susceptible to variation in serum plasma level, especially in the third trimester and regularly require increased dosages in latter stages of pregnancy.
Anti-Seizure Medications Safety Profiles
Poorly controlled epilepsy is not without serious risk to pregnant women. While these are rare, many are often preventable. Maternal mortality reports across the UK and Ireland frequently refer to maternal deaths where patients had stopped their medication due to pregnancy. Ensuring patients are fully informed of the often reassuring safety profile of their medication and providing them with accurate, up to date information are key to caring for women with epilepsy. Patients with epilepsy should be advised not to stop taking their anti-seizure medication without first speaking to their doctor.
woman prescribed Valproate does not stop taking it without consulting their doctor. Should a woman who is taking valproate become pregnant an urgent review with a neurologist should be arranged.
LAMOTRIGINE LEVETIRACETAMANDare amongst the most commonly prescribed antiseizure medications in use today and pose no additional risks to the fetus in pregnancy. The background rate of all congenital anomalies (babies born with structural birth defects) in pregnancy is approximately 2% and neither of these drugs affect this rate. Patients taking these medications should be reassured that they are safe to take in pregnancy and that they should be encouraged to continue to take their medications to reduce seizure risks. Studies in relation to risk of developmental delay are also reassuring.

In Ireland approximately 25% (10000) of all people diagnosed with epilepsy are women of childbearing potential. Pharmacists are among the most trusted professions by society and are ideally placed to support and advise women who maybe planning a pregnancy or indeed are pregnant. Whether at the point of collecting prescribed regular anti-seizure medication or indeed at initiation or ceasing of contraception, opportunities exist for pharmacists to discuss pregnancy in women with epilepsy.

efficacy of the combined oral contraception. Lamotrigine levels can be affected by the combined oral contraceptive pill and can lead to toxicity side effects on the pill free interval. The FSRH have excellent guidance on contraceptive use for women taking anti-seizure medication.
Fortunately most women with epilepsy remain well during their pregnancy. However, up to 30% of women with epilepsy will notice a worsening of seizure control in pregnancy which can place mothers and their unborn babies at risk during the pregnancy. Some of the most commonly prescribed anti-seizure medications enjoy excellent safety profiles. None the less pregnant women often have significant anxiety around taking medication.

Ideally a pre-pregnancy serum level at a time of good seizure control or an early pregnancy level is taken in order to have a target pregnancy level. Levels are then repeated each trimester to maintain target levels. Often patients will remain on a higher dose for the initial two weeks postpartum due to the increased fatigue related seizure risk at this time. Any postpartum dose changes should be made following consultation with their neurology team. It should be noted that the use of drug levels varies in clinical practice and some studies do not support routine use. Should a pregnant woman experience a seizure a drug level is always taken and doses often increased prior to the result being available.

1mg/ml concentrate for solution for infusion. Your patients, your profession, our passion.
Launching Noradrenaline
ABBREVIATED PRESCRIBING INFORMATION: Consult the Summary of Product Characteristics for further information. Additional information is available upon request. Noradrenaline (Norepinephrine) Kabi 1mg/ml concentrate for solution for infusion. Active ingredient: 1ml concentrate for solution for infusion contains 1mg noradrenaline (norepinephrine) base equivalent to 2mg noradrenaline (norepinephrine) tartrate. Contains 3.4mg sodium per ml. Indications: In adults for use as an emergency measure in the restoration of blood pressure in cases of acute hypotension. Posology and method of administration: When diluted as recommended, each litre contains 40mg noradrenaline base equivalent to 80mg noradrenaline tartrate. If dilutions other than 40mg per litre are used, check infusion rate calculation carefully before starting treatment. Initial rate of infusion – 10-20ml/hour (0.16-0.32ml/min); equivalent to 0.4-0.8mg/hour noradrenaline base. Lower initial infusion rate of 5ml/hour (0.08ml/min); equivalent to 0.2mg/hour noradrenaline base may be preferred. Titration of dose – Once infusion has been established, titrate dose in steps of 0.05-0.1mcg/kg/min of noradrenaline base according to pressor effect observed (see SmPC for details). Continue infusion until adequate blood pressure and tissue perfusion maintained without therapy. Carefully monitor patient. Should only be administered by healthcare professionals familiar with use of noradrenaline and with appropriate monitoring facilities. Avoid abrupt infusion withdrawal; reduce infusion gradually. No experience in treatment of hepatic or renal impairment. Dose selection for an elderly patient should be cautious, starting at the low end of the dosing range. Safety and efficacy in patients less than 18 years old has not been established. Method of administration – Intravenous use only after dilution. Infuse at a controlled rate using either syringe pump, infusion pump or drip counter. Administer via a central venous catheter. If not using a central venous catheter administer into a large vein whenever possible, particularly an antecubital vein to minimize risk of ischemic necrosis. Avoid catheter tie-in technique if possible. Contraindications: Hypersensitivity to the active substance or to any of the excipients, hypotension due to blood volume deficit. Do not use with cyclopropane and halothane anaesthetics as this may cause serious cardiac arrhythmias including ventricular fibrillation. Special warnings and precautions for use: Do not use undiluted. Contraindicated in patients who are hypotensive from blood volume deficits except as an emergency measure to maintain coronary and cerebral artery perfusion until blood volume replacement therapy can be completed. Should only be used in conjunction with appropriate blood volume replacement. If whole blood or blood plasma is indicated to increase blood volume, administer separately (e.g. use Y-tubing, individual containers). Prolonged administration may result in plasma volume depletion which should be continuously corrected by appropriate fluid and electrolyte replacement therapy. Frequently check blood pressure and rate of flow to avoid hypertension. Particular caution in patients with coronary, mesenteric or peripheral vascular thrombosis, hypotension following myocardial infarction, angina (particularly Prinzmetal’s variant angina), diabetes, hypertension or hyperthyroidism, major left ventricular dysfunction associated with acute hypotension (supportive therapy should be initiated simultaneously with diagnostic evaluation; reserve noradrenaline for patients with cardiogenic shock and refractory hypotension, in particular those without elevated systemic vascular resistance), liver failure, severe renal dysfunction,

ischemic heart diseases and elevated intracranial pressure. Reduce dose if heart rhythm disorders occur during treatment. Cardiac arrhythmias may arise when used in conjunction with cardiac sensitizing agents and may be more likely in patients with hypoxia or hypercarbia. Elderly patients may be especially sensitive to the effects of noradrenaline. Not recommended in children. Where indicated, appropriate replacement therapy of blood or fluid together with adoption of the supine position with elevation of the legs, must be instituted and maintained prior to and/or during therapy with noradrenaline. During infusion, record blood pressure every two minutes from the time the administration started until the desired blood pressure is obtained and then every five minutes thereafter if infusion continued. Constantly watch flow rate and never leave patient unattended. Hypertension may eventually lead to acute pulmonary oedema, arrhythmia or cardiac arrest. Caution in patients receiving pressor amines with chloroform, enflurane or other halogenated anaesthetics (may cause serious cardiac arrhythmias) or any other cardiac sensitising agent or in patients who exhibit profound hypoxia or hypercarbia. Extreme caution in patients receiving monoamine oxidase inhibitors or within 14 days of cessation of such therapy and in patients receiving tricyclic antidepressants, adrenergic- serotoninergic drugs or linezolid. Overdoses or conventional doses in hypersensitive persons may cause severe hypertension with violent headache, photophobia, stabbing retrosternal pain, pallor, intense sweating and vomiting. The infusion site should be checked frequently for free flow. Care should be taken to avoid extravasation of noradrenaline tartrate into the tissues, as local necrosis might ensue due to the vasoconstrictive action of the drug (see SmPC for antidote for extravasation ischaemia). Blanching along the course of the infused vein warrants consideration of changing infusion site at intervals. Avoid administration via the veins of the leg in elderly patients or in those suffering from occlusive vascular diseases. Noradrenaline interacts with other medicinal products; some combinations are inadvisable or require additional precautions and close medical supervision – see SmPC. Undesirable effects: Anxiety, insomnia, confusion, weakness, psychotic state, transient headache, tremor, acute glaucoma, bradycardia, arrhythmia, electrocardiogram change, tachycardia, cardiogenic shock, stress cardiomyopathy, palpitations, increase in the contractility of the cardiac muscle resulting from the beta- adrenergic effect on the heart (inotrope and chronotrope), acute cardiac insufficiency, hypertension, peripheral ischaemia including gangrene of the extremities, plasma volume depletion with prolonged use, dyspnoea, respiratory insufficiency or difficulty, nausea, vomiting, paleness, scarification of the skin, bluish skin colour, hot flushes or skin redness, skin rash, hives or itching, retention of urine, extravasation, necrosis at injection site.

Symptoms of Allergic Rhinitis
It is estimated that over 80% of people with asthma have allergic rhinitis (AR). AR is also a risk factor for asthma. 10-40% of people who have AR also have asthma. AR is more likely to develop initially with asthma developing later. Therefore, people with AR should be assessed for asthma due to the increased risk of developing asthma. Similarly, patients with persistent asthma should be assessed for AR.
Classification
The exact cause of asthma remains unknown. Numerous triggers can cause symptoms, and these differ from person to person. As spring and summer emerges, this can be a challenging time as various pollen levels start to increase.

Removal of mucous and inflammatory mediators
The clinical features of asthma (wheeze, cough, shortness of breath and chest tightness) result from changes in the airways as a result of abnormal sensitivity called bronchial hyper-reactivity. The muscle of the bronchial walls becomes hypertrophied causing occlusion of the airway resulting in constriction of the muscle causing bronchospasm. Secondly, in the mucosal, submucosa and smooth muscle layers of the bronchi and bronchioles, inflammatory cells infiltrate. Eosinophils, neutrophils, macrophages, mast cells and plasma cells are found in varying numbers. All these cells contain chemical mediators that produce

The current COVID-19 pandemic has shifted attention away from the human immunodeficiency virus (HIV) pandemic which has been ongoing for 40 years and has claimed over 36 million lives. And it is not over – currently there are more than 37 million people living with HIV. Until the mid-1990s, a positive HIV test meant almost certain progression to death within 10-15 years, but now with antiretroviral therapy (ART), HIV-positive people can live relatively normal healthy lives. Over 60% of people with HIV live in sub-Saharan Africa, and equitable access to ART in these regions took many years. But now over 27 million people worldwide are on ART for HIV - about 73% of the people who need it. With 1.5 million new infections every year and the majority being treated, the number of people living with HIV is increasing year on year.
The immunodeficiency caused by HIV is the result of the virus infecting and killing CD4 T cells. CD4 T cells are the commanders of adaptive immune responses. They learn the nature of the threat to the body, be it a virus, a bacterium, a parasitic worm or a tumour, and they release cytokines, chemical messengers that recruit and activate the appropriate weapons of the immune response. But CD4 T cell numbers decline during HIV infection and when they drop below 200 per microlitre of blood, the body is defenseless against a myriad of pathogens and tumours, the condition termed the acquired immunodeficiency syndrome (AIDS). People with AIDS are susceptible to infections by many pathogens, with tuberculosis being the most common cause of Despitedeath.the major advances in vaccine development, a vaccine
against HIV has yet to be produced. To date, the best result has been the RV144 clinical trial, which was tested on more than 16,000 subjects and resulted in 31% protection against persistent HIV infection after 3 years. There are several reasons for the failure to develop an efficacious vaccine against HIV. In addition to the depletion of CD4 T cells, which are required for responses to vaccines, HIV has evolved many tricks to evade or subvert the immune system. Being an RNA virus, HIV is particularly susceptible to mutations occurring during replication, leading to the generation of new variants that escape recognition by T cells and antibodies. HIV can exist in latent form with its genome integrated into the host cell genome and no virus particles present, making it invisible to the immune system, but capable of later re-emerging as replicating virus. HIV also produces a protein, called Nef, which can specifically inhibit components of the immune system.
Three subsets of innate T cells are depleted from the circulation of people with HIV and especially people who progress to AIDS. These are natural killer T (NKT) cells, mucosa-associated invariant T (MAIT) cells and a subset of gamma/delta (γδ) T cells, termed Vδ2 T cells. These depletions could be due to activationinduced cell death, killing by the virus, or migration to particular tissues such as the gut, but several lines of evidence suggest that they are contributing to immunity against HIV. In particular, Vδ2 T cells which recognize phosphate antigens, can kill HIV-
Innate T cells show promise as targets for therapy for HIV infection. Since they are activated by conserved non-peptide ligands, they can be easily expanded to high numbers in tissue culture. Their functions can be ‘tweaked’ to optimise their antiviral activities by stimulating with various synthetic ligands in the presence of particular cytokines. Clinical trials involving NKT cells and γδ T cells are ongoing in cancer patients with promising results. The next step is to take these treatments into patients with infectious disease, and HIV remains the holy grail for such therapies.
As mentioned above, CD4 T cells are the commanders of the immune system. CD4 T cells give the orders to CD8 T cells and other cells to kill virus-infected cells. CD4 and CD8 T cells have cell-surface antigen receptors that specifically recognize peptide fragments of proteins derived from viruses and other pathogens, allowing exquisite specificity in adaptive immune responses. Less studied are ‘innate T cells’ - unconventional T cells that do not recognise peptides - instead they recognize lipids, phosphates or other metabolites produced by pathogens or by host cells in response to infection by pathogens. Many of the antigens recognized by innate T cells are common to many different microorganisms, meaning that innate T cells do not display the high degree of antigen-specificity seen for conventional T cells. However, innate T cells exhibit many properties that make them essential contributors to antiviral immunity. Firstly, they recognize antigens that are not encoded by DNA and therefore are not subject
to mutational changes. Secondly, while conventional T cells take several days to differentiate into effector cells after antigen recognition, innate T cells exist as effector cells and can elicit their effector functions within minutes. Once activated, they can kill virusinfected cells and release early bursts of cytokines that recruit and activate other cells of the immune system, thereby shaping and polarizing adaptive immune responses. Innate T cells can activate and regulate dendritic cells, macrophages, neutrophils, natural killer cells, myeloidderived suppressor cells and conventional T cells via contactdependent and cytokine-mediated interactions. Importantly, innate T cells can promote antigen presentation by dendritic cells and antibody production by B cells – essential for immunity against viruses. Furthermore, they can selectively promote or suppress the responses of other immune cells. Research by us and others is attempting to figure out how to selectively turn on or off individual functional activities of innate T cells in order to therapeutically activate the appropriate immune responses to combat particular pathogens.
infected cells, including latentlyinfected cells, and inhibit HIV replication within cells. Therefore, it is likely that restoration and activation of Vδ2 T cell numbers will promote immunity against HIV and may be used as an adjunct to ART. Immunotherapies utilising Vδ2 T cells are showing promise in clinical trials for cancer. Strategies employed include in vivo activation of Vδ2 T cells using phosphate antigens – this can be achieved using bonelicencedanddrugs,aminobisphosphonatesuchaszoledronatepamidronate,whichareforthetreatmentofresorptiondiseasesbut also activate Vδ2 T cells by inducing the production of endogenous phosphates. Alternatively, Vδ2 T cells can be isolated from patients’ blood and expanded ex vivo using aminobisphosphonates or phosphate antigens, before being adoptively transferred back to the patient. Similar clinical trials for cancer are ongoing using glycolipids to activate NKT cells either in vivo or ex vivo in adoptive transfer regimens. Future work is required to determine if innate T cells can similarly be used to treat infectious diseases.

There is a global epidemic in obesity in adults and children, with obese people predisposed to develop diabetes, cardiovascular disease, and cancer. New therapies are needed to help tackle this issue. In their research, the scientists identified how “checkpoint proteins” and immune cells alter inflammatory cells within the fat tissue to cause obesity. In people with obesity (Body Mass Index BMI> 30 kg/m2) these changes in checkpoint expression in the visceral fat was predictive of the person’s weight. The scientists then showed that modifications in the so-called immune checkpoint proteins of mice on a Western “high fat” diet were linked to dramatic reductions in the development of obesity and diabetes. The study, just published in the leading international biomedical journal Science Translational Medicine, was led by Professor Padraic Fallon from Trinity College Dublin’s School of Medicine, and Dr Christian Schwartz, a former EMBO Fellow in Trinity and now a Principal Investigator at the University Hospital Erlangen. Professor Fallon, who is based in the Trinity Biomedical Sciences Institute, commented, “This new process of checkpoint regulation of cells in visceral fat of obese individuals advances our understanding of how the immune system controls diet-induced weight gain that can lead to conditions such as obesity and type 2 diabetes. “Our discovery has broader impacts on addressing how obesity influences co-morbidity with other diseases, as shown in the COVID-19 pandemic, where obese individuals that are infected with SARS-CoV-2 are more likely to develop severe disease that requires intensive care and also have an increased risk of mortality.”
Irish and German scientists have just identified how specific immune cells can work together in fat to cause inflammation that leads to weight gain and obesity. Their work pinpoints new avenues to exploit the regulation of that inflammation in fat tissue, thereby suggesting new ways to manage obesity.

VDJ sequences. This process produces long-lived plasma cells that provide durable, sustained antibody production. These cells reside in the bone marrow (BM) and are an important part of humoral immunity. Abnormal clonal plasma cell development mimics these normal biological processes but results in excessive amounts of intact immunoglobulin. These malignant plasma cells chiefly reside in the BM, but can also be found in the peripheral blood and other extramedullary sites, including soft tissue and organs. This is particularly true of the latter stages of the disease. MM is character¬ised by the secretion of a monoclonal immunoglobulin protein (known as M protein or monoclonal protein). This aberrant protein is made by the aforementioned abnormal plasma cells. In 15–20% of patients, the MM cells secrete only monoclonal free light chains, and, in <3% of patients, these cells secrete no monoclonal protein. The clinical features of multiple myeloma are typically driven by monoclonal protein, the malignant cells or cytokines secreted by the malignant cells.

Introduction
Multiple myeloma progression
Importantly, MM exists in a spectrum of disorders referred to as monoclonal gammopathies. Within this grouping, monoclonal gammopathy of undetermined significance (MGUS) is characterised by infiltration of clonal plasma cells into the BM and secretion of monoclonal protein, and is the most common form. MGUS is asymptomatic and consistently precedes the development of MM. Typically, MGUS demonstrates low levels of abnormal protein (<3.0 g/dL), abnormal plasma cells (<10%) and patients do not exhibit CRAB features. A proportion of patients experience an intermediate stage, referred to as smouldering multiple myeloma (SMM), with elevated abnormal protein (>3.0 g/dL) and plasma cells (>10 and <60%), but again without CRAB features. Around 15% of MGUS patients subsequently progress to active MM, and approximately 20% progress to myeloma or a related condition (AL amyloidosis, Waldenstrom macroglobulinaemia or a lymphoproliferative disorder).

Tumour cells rely on survival mechanisms that are imprinted during cellular lineage development: lineagedependency. Bortezomib, a first-in-class proteasome inhibitor (PI), has clearly demonstrated the dependency of MM cells on the protein quality control pathway as a therapeutic target. The ubiquitin-proteasome system (UPS) is the main mechanism for maintaining protein homeostasis. In MM, increased aberrant protein turnover and immunoglobulin production exerts robust pressure on this system, making it exquisitely sensitive to proteasome inhibition. Exploiting this vulnerability with a PI, such as bortezomib, is a logical first-line and (typically) successful treatment approach. However, bortezomib has broad, pleiotropic effects. It triggers intrinsic and extrinsic myeloma cell apoptosis and cell cycle arrest. It also modifies bone turnover and osteoclast activity in the bone marrow. Furthermore, bortezomib inhibits the NF-κB pathway (via degradation of its inhibitor, IκB). NF-κB is a major oncogenic pathway in MM: it mediates MM cell survival and DNA repair, promotes interactions of MM cells with BM stromal cells via the transcription of adhesion molecules, as well as modulating the transcription and release of cytokines in the BM microenvironment (such as IL-6, VEGF, IGF-1), which in turn mediate MM growth and drug resistance, and confer immunosuppression in the BM milieu. Subsequent generations of orally available PI (including carfilizomib and ixazomib) were developed to help overcome bortezomib resistance and offer additional PIs to the associatedanddeubiquitylatingTherapeutictoemergedofTargetingarmamentarium.upstreamcomponentstheUPShasalsorecentlyasapromisingstrategyovercomePIresistance.targetingofenzymes(DUBs)the19Sproteasome-ubiquitinreceptor

Given the genomic complexity of MM, more sophisticated techniques including gene expression profiling, mutational status, and copy number abnormalities have been used, alone or in combination with FISHbased approaches, to more deeply characterise disease biology and prognosis. For example, newly diagnosed MM (NDMM) patients carrying del(17p) may be further stratified using subclonal analysis. Targeted sequencing has been used as an alternative to whole exon sequencing to specifically analyse fractions of the genome and provide more accurate risk stratification. Although not yet widely incorporated into practice, these approaches will help to define future personalised treatment strategies in MM.
The primary genomic events involved in MM are the acquisition of hyperdiploidy or translocations affecting the IGH genes; these events are mutually exclusive. Secondary genomic events include chromosomal translocations, copy-number variations and single-nucleotide variants Genomic events underlying MM affect multiple signalling pathways including MYC, NF κB, and MAPK pathways, plasma-cell differentiation, cell-cycle regulation and DNA-damage sensing and

Prognostic Factors
Specifically, diagnosis of MM requires 10% or more abnormal plasma cells in the BM plus one or more signs of end-organ damage (CRAB). Even without CRAB features, patients who exhibit myeloma-defining events (clonal BM plasma cells of >60%, serum : ratio >100 fold, and/or >1 bone focal lesion on magnetic resonance imaging (MRI) or positron emission tomography (PET)/computed tomography (CT) scan are also treated, as the risk of progression to symptomatic disease is approximately 80% at 2 years. Most recently, nextgeneration sequencing (NGS) analysis of MGUS-SMM-MM patients has proven to be a useful tool to decipher the chronology of disease initiation events. In the near future, the combination of genomic signatures and biomarkers of disease burden might enable identification of those SMM patients who could benefit from early intervention to avoid progression to MM.

Historically, MM was associated with a poor prognosis, with a 5 year age-standardised overall survival rate of 27.5% (according to Irish data from 1994-1998). The subsequent introduction of novel drugs: proteasome inhibitors (PIs), immunomodulatory drugs (IMiDs), and potent monoclonal antibodies (mAbs) significantly improved the clinical outcomes of patients with MM and drove up the 5-year overall survival to 52.1% in Ireland, which is comparable to other jurisdictions (52.6 % for the U.K., 54.0% for the USA). However, progress has plateaued at this level. There is an urgent need to redouble our research efforts to unstick and build upon the advancements made to date.

Increasing interest surrounds the use of microRNA-targeting strategies in MM. Preclinical data have defined their oncogenic (miR-221/222,-21,-17-92 cluster) or tumour suppressive (miR29b,-34a,-125b,-15,-16) roles in MM associated with repression or overexpression, respectively, of genes involved in essential pro-survival pathways. Several candidates are being tested in other diseases and will soon be evaluated in MM, using miRNA replacement or inhibition strategies. Theoretically, as they are endogenous antisense of mRNAs, their replacement is hypothesised to induce a “natural” effect on the targets, with less off-target effects compared to siRNA-mediated targeting strategies. In addition, the recent availability of suitable in vivo delivery systems now permits their use in clinical trials.
Targeting the tumour-bone marrow interfacemicroenvironment
Global hypomethylation of the genome characterises the MGUS>MM transition. In contrast, pervasive genome re-methylation occurs in the transition from MM to a more aggressive plasma cell leukaemic stage. Specific epigenetic targets include the type II arginine methyltransferase PRMT5 in MM. Inhibition of PRMT5 results in MM cell killing via NF-κB blockade, thus providing the rationale for clinical trials targeting PRMT5 in MM.
Lineage vulnerabilities in MM also include aberrant transcription factor (TF) regulatory networks controlling the lineage factor IRF4. However, direct targeting of TFs is a challenging strategy and there are no inhibitors for clinical use available at present. Notably, repression of IRF4 transcription is observed posttreatment with lenalidomide, which triggers cereblon (CRBN)mediated degradation of the IRF4 transcriptional activator IKZF3. Building on this knowledge, a new platform technology has been developed to trigger selective protein degradation. Proteolysistargeting chimeras (PROTACS) are designed by conjugating the small-molecule binder of the target protein to an E3 ubiquitin ligase binding scaffold such as the analogs of thalidomide which bind CRBN. This exciting approach will allow for therapeutic degradation of protein substrates that are otherwise difficult to target.
noting that the role of mutations in MM has not been fully elucidated, only TP53 mutation (affecting 6-8% of newly diagnosed patients) demonstrably confers worse outcome. Related to this, tumour-targeted treatments in MM are often compromised by intra-clonal heterogeneity. Deep sequencing has identified a complex subclonal structure in MM with different patterns of clonal evolution impacted by BM, immune response, and therapythus making successful targeting of the above highly difficult. p
toxicity. Another novel and attractive approach to overcome PI resistance is the concomitant blockade of the aggresome/ autophagy pathway using an inhibitor of histone deacetylase 6 (HDAC6), which is recruited to maintain proteostasis balance as an adaptive response mechanism. Several groups, including our own, are actively pursuing the development of novel targeted, selective HDAC6 inhibitors with therapeutic potential.

the IMiDs (which remain active against MM even in the protective milieu of the BM. Cellular and non-cellular components of this niche support MM cell proliferation, migration, survival and drug resistance, while also conferring immunosuppression, and therefore represent targets for novel therapeutics under investigation by our group and others. Disease progression is mediated by intrinsic factors of the clonal cells along with factors that mediate a permissive tumour microenvironment. The MM tumour niche comprises the components of the BM microenvironment–cellular (stromal cells, osteoblasts, osteoclasts, endothelial cells and immune cells) and noncellular extracellular matrix (ECM).
Histone deacetylases (HDAC) are generally hyperactive in MM. HDAC inhibitors are the most studied epigenetic drugs that have led to clinical trials and
approval of the non-selective HDAC inhibitor panobinostat in combination with bortezomib in relapsed/refractory disease. Increased toxicity observed with panobinostat prompted the development of HDAC6selective inhibitors (ricolinostat and citarinostat/ACY-241), which show promising results and lower toxicity in combination with bortezomib and dexamethasone.
Comprehensive clinical trials have led to the approval of the IMiD thalidomide and its more potent analogs lenalidomide and pomalidomide for treatment of MM and RRMM. These agents exert direct effects on MM cells including growth arrest and caspase-8-mediated apoptosis, associated with CRBN-dependent degradation of IKZF1/3 followed by IRF4 downregulation, as mentioned earlier. In the BM microenvironment, IMiDs abrogate MM cell adhesion to the BM, modulate cytokine and growth factor secretion, inhibit angiogenesis and upregulate T-, NK-, and NK-T-cell-based immunity while downregulating T-reg cells.

Frequent gene mutations in MM include RAS (KRAS or NRAS) with downstream activation of the MAPK pathway, BRAF, DIS3, and FAM46C. Other signalling pathways affected include the NF-κB pathway (affected by copy number loss, mutation, and translocations) and the PI3K pathway (dysregulated in the absence of genetic change). Apoptotic pathway dysregulation occurs, with BCL2 dependency in patients with t(11;14) and MCL1 dependency in other patients observed. However, it is worth

Epigenetic alterations affect regulation of gene activity and expression, without altering gene sequence. Such alterations are associated with MM onset and progression, and modulate several important biological processes.
Combinatorial approaches targeting MM cells, disrupting MM cell/BM interactions and augmentation of anti-MM immune responses have dramatically improved treatment responses and duration. Key obstacles to overcome MM mortality include (i) constitutive and evolving genomic heterogeneity in MM cells, as well as (ii) the immunosuppressive BM milieu. Going forward, integration of multi-omics sequencing technologies profiling both the MM cell and BM accessory/immune cells will help identify therapeutic targets and translate to novel rationally designed, selective, targeted and immune therapies. Past successes have shown usthe future is bright for MM research!

Cellular therapies, in particular chimeric antigen receptor (CAR) T-cell approaches are under active investigation and receiving a lot of attention owing to their success in other haematologic conditions (particularly diffuse large B cell lymphoma and mantle lymphoma). Their success is predicated on the identification of unique and highly expressed MM antigenic targets. Among a variety of targets, B-cell maturation antigen (BCMA/TNFRSF17) is the most frequently used due to its selectivity for normal plasma and MM cells. Several CAR-T products have been clinically tested in heavily pre-treated (PI-IMiD-CD38 mAb) RRMM, and have demonstrated remarkable, deep MRD responses. Increased clinical use of and experience with such therapies has also helped to ameliorate the more commonly observed toxicities of CAR-T cells (cytokine release syndrome and neurotoxicity). To date, however, most patients have relapsed, and ongoing research is assessing mechanisms of resistance to CAR-T, utilising combination immune approaches with CAR-T, and using CAR-T earlier in the disease course in order to achieve more durable responses.
There have been incredible advances in the range of therapies available to clinicians treating MM. Despite this, management of MM patients remains challenging: acquisition of resistance underlies relapse in most patients. The development of second-generation potent drugs of the same class has helped to overcome both PI and IMiD resistance, as have combination therapies MULTIPLE MYELOMA
with agents targeting pathways mediating resistance. Identification of biomarkers of patient MM resistance/sensitivity may further inform sequential and combination therapies in the future. The first example of biomarker-driven anti-MM treatment in MM is the Bcl-2 inhibitor venetoclax/ABT199, whose safety and efficacy are predicated upon occurrence of t(11;14) or presence of high levels of BCL2. Several trials in RRMM demonstrate the efficacy of venetoclax, as monotherapy and in combination, restricted to this patient subset.

Loss of immune surveillance supports MM tumour growth and resistance, and is associated with alterations in nonlymphoid and immune cells in the bone marrow. There is also increasing evidence that evolving immune dysfunction is an important determinant of progression from MGUS/SMM to symptomatic MM. Immune escape is also mediated, at least in part, by increased expression of immune checkpoints, i.e., PD-1/PD-L1, in T cells and MM cells. Alas, results with immune-checkpoint blockade via PD-1/PD-L1 in MM have been disappointing thus far. No single agent activity of the humanised anti-PD-1mAb pembrolizumab has been shown, and importantly, two randomised clinical trials
Daratumumab, in particular, has shown remarkable efficacy and frequency of response.

to CRBN has been implicated in mediating the immune effects of IMiDs, as IKZF1/3 degradation in T cells increases their secretion of cytokines, notably IL-2. This mechanism is also associated with increased NK and NK-T-cell cytotoxicity and antibody-dependent cellular cytotoxicity (ADCC) (i.e., antiCD38, daratumumab and -CD20, rituximab) observed after IMiD treatment. Preclinical and clinical studies confirm the strong synergism of IMiDs with PI and with mAb treatment.
Looking to the future
Elotuzumab and daratumumab target SLAMF7 and CD38, respectively. Elotuzumab also activates NK cells and is approved in combination with lenalidomide or pomalidomide in RRMM.
Agents targeting novel MM vulnerabilities are urgently needed. Resistance is now beginning to appear for immune-based approaches. Loss of targeted antigens (such as BCMA, CD38) is a common event, either due to loss with tumour evolution or to suppression in the face of immune pressure. Multi-antigen targeting may potentially overcome this obstacle, and several trials are evaluating this strategy. Additional resistance may be intrinsic to the technology or modality, for example ongoing efforts are directed at increasing CAR-T cell expansion and persistence in vivo to promote CAR-T cell persistence. Lastly, T-cell exhaustion and the immunosuppressive BM may contribute to both targeted- and immune-therapy resistance.
Monoclonal antibody technologies have also provided the framework for the development of Ab-drug conjugates (ADC) and bispecific T-cell engagers (BiTE). B-cell maturation antigen (BCMA)directed ADCs are currently under investigation in both preclinical and clinical settings, and represent a promising approach due to the highly specific expression of BCMA on MM cells and role of the BCMA/ APRIL pathway in supporting MM cell survival in the BM.

• 70% reduction in wait time in an Emergency Department
“However the appropriate education to allow for the implementation of these medical advances in an effective, efficient and safe way remains inadequate”
The Irish Society of Physiotherapists (ISCP) has launched a Competency Framework for Advanced Practice Physiotherapists and calls on Government to amend the legislation to allow physiotherapists to refer for X-ray and create the Advanced Practice Physiotherapy (APP) grade, both of which will achieve significant cost savings to the health service.
Speaking at the launch, Dr Marie Ó Mír, ISCP Advanced Practice Officer said, “For over two decades physiotherapists with extensive post graduate experience and qualifications have been working in roles with advanced scope, but lack of a standardised approach has led to much variation in roles. This framework was developed to support the delivery of safe and effective expert services to the public and to demonstrate the ISCP’s commitment to working with the Department of Health and HSE in developing policy for the implementation of the advanced practice grade.”

Pharmacists and their teams should ensure an appropriate dosing schedule has been prescribed for the specific indication. Apixaban and dabigatran should always be prescribed twice daily in the setting of AF and any alternative dosing schedule should be queried.
DOAC Dosing and Method of Administration
Table 1 36 CARDIOLOGY

In the case of twice daily DOACs the administration times should ideally be at 12 hourly Dabigatranintervals.isnot suitable for MDS dispensing and should always be supplied to the patient in its original packaging. Where patient adherence would be compromised by supplying dabigatran separately this should be discussed with the prescriber. There is likely an alternative DOAC the patient could be switched to which is suitable for MDS dispensing, thereby increasing adherence and safety.
The risk of stroke is calculated using the CHA2DS2-VASc Score as outlined in Table 1. For most patients with AF we err on the side of anticoagulation. The European Society of Cardiology (ESC) recommends that all patients scoring 1 or greater should be considered for OAC (except females scoring only 1 on the basis of gender alone who are considered low risk).
Anticoagulation in Atrial Fibrillation: The Role of the Pharmacist
There are four DOACs currently available – dabigatran, apixaban, rivaroxaban and edoxaban. All are licensed for a number of different indications and have different dose reduction criteria. The HSE medicines management programme have produced a succinct table1 which amalgamates the information from the four individual summary of product characteristics (SPCs) and is very useful as a quick reference guide.

risk factor, all patients with AF will eventually qualify for lifelong anticoagulation therapy and so it is really important for pharmacists to have an in-depth understanding of these medications.
Written by Christine McAuliffe, MPSI.
It is possible to confirm that an appropriate dose of DOAC has been prescribed in some situations. For example a reduced dose of dabigatran is recommend for all patients 80 years and over and the presence of certain P-glycoprotein (P-gp) inhibitors necessitates a licensed dose reduction for both edoxaban and dabigatran. Where such cases are encountered in the pharmacy it should be flagged to the prescriber and a dose reduction recommended.
There are other prescribing decisions which are less clear-cut e.g. where patients prescribed dabigatran are between 75 and 80 years old or have gastritis. In these cases prescribers are advised to consider a dose reduction. These decisions are made on a risk-benefit basis and it can be difficult for pharmacists to make meaningful clinical interventions around dosing for these patients in the absence of a full clinical history. FOCUS:
All four DOACs are renally cleared to some degree. Therefore creatinine clearance must be calculated using the Cockroft and Gault equation at initiation of therapy and recalculated periodically to ensure accurate dose selection. In hospital, with access to laboratory results, one of the primary roles of the pharmacist in relation to anticoagulant therapy is confirmation that the patient is prescribed the appropriate dose for their renal function. Both overand under- dosing in the area of anticoagulation puts the patient at risk of the severe consequences of either a serious bleeding event or stroke.
Atrial Fibrillation (AF) is the most common sustained cardiac arrhythmia affecting at least 3% of the Irish population currently. AF is an age-related condition with worldwide prevalence predicted to more than double in the coming decades. This presents a significant health burden as almost one in every three strokes are associated with AF and AFrelated strokes tend to be more severe, posing the greatest risk for neurological includesManagementdisability.ofAFgenerallytheimplementation of
Christine is the lead clinical pharmacist in Tallaght University Hospital’s interdisciplinary Atrial Fibrillation clinic.

In this article she outlines some of the main practice points for pharmacists to be aware of when looking after these patients and highlights some useful reference sources.
Introduction
There are however a number of checks that can be performed in the community pharmacy setting to ensure safe DOAC prescribing and dispensing without the need to access laboratory results.
Direct Oral Anticoagulants (DOACs) have widely replaced warfarin as the agents of choice due to their efficacy, convenience and reduced, but by no means eliminated, potential for interactions. As increasing age is a prominent AF
Written information should be provided. An alert card is included in the packaging of each of the four DOACs and patients should be advised to carry this on their person at all times. The Irish Medication Safety Network (IMSN) have produced a patient information booklet on anticoagulation in AF. It contains information on the condition of AF and includes general and specific information on all four DOACs. It can be accessed, along with the link to a patient safety video, on the IMSN website
A complex scenario arises when AF patients undergo coronary stenting. Such patients will require a period of treatment with “triple therapy” following their stenting procedure i.e. dual antiplatelet therapy (with clopidogrel and aspirin) and a DOAC. Where such a situation arises clear instruction from the cardiology team in secondary care should be communicated to the patient, the GP and the pharmacist outlining the short, intermediate and longterm plan for antiplatelet and DOAC therapy.

Interactions
DOAC pharmacokinetics are affected by concomitant administration of medications which either inhibit or induce the P-gp transporter and/or CYP3A4 isoenzyme. Some combinations such as dabigatran and the P-gp inhibitor dronedarone are contraindicated by the manufacturer due to an unacceptable increase in plasma concentrations of DOAC. The EHRA guide contains information on additional potential interactions not included in the SPCs and also provides some guidance around instances where a
In most instances DOACs should not be prescribed alongside other anticoagulants and any such prescription should be clarified with the prescriber. An exception however is the scenario where a patient is switching from DOAC to warfarin therapy where continuation of DOAC may be required for a

Interactions affecting DOACs can be pharmacokinetic or pharmacodynamic in nature. For the most part information on important interactions can be found in the SPC and/or the BNF - reference sources familiar to all pharmacists. The European Heart Rhythm Association (EHRA) have produced a Practical Guide2 on many different aspects of DOAC therapy in AF. The guide was first produced in 2013 and is currently in its third iteration. It contains a wealth of information in relation to DOAC prescribing and ongoing monitoring and is one of the key references I consult regularly. The EHRA guide includes an extensive section on DOAC interactions which is a really useful resource for pharmacists in practice.

Patient and carer education is one of the most important interventions by healthcare professionals (HCPs) for patients on DOACs. In-depth education should be provided at initiation of DOAC therapy and reinforced periodically thereafter. Patients should be counselled on the following points - indication for DOAC therapy, importance of strict adherence (no DOAC = no protection from stroke), modality of intake (once or twice daily, intake with food for rivaroxaban etc.), management of missed doses, increased risk of bleeding, over the counter medications to avoid and advice given to inform HCPs of DOAC therapy in advance planned procedures (dentist etc.).
Selective serotonin reuptake inhibitors (SSRIs), and other antidepressants with affinity for serotonin receptors, are associated with an increased risk of bleeding. This risk increases further in the presence of DOACs. Where a combination of medications which increase a patients bleeding risk are co-prescribed, it’s worth highlighting that gastroprotection with a proton pump inhibitor or H2-receptor antagonists should be considered.
been associated with reduced adherence. Patients who report missing doses of a twice daily DOAC despite adequate education should be advised that there are once daily DOAC options available and should be referred to the prescriber for consideration of a switch in therapy.

Patient Education and Adherence
drug-drug interactions generally involve the co-prescription of medications which increase the risk of bleeding. Patients taking DOACs should be advised to avoid the use of nonsteroidal anti-inflammatory drugs. The concomitant administration of a low dose antiplatelet such as aspirin or clopidogrel with a DOAC is indicated in some instances. However, pharmacists should query the ongoing need for antiplatelet therapy in patients who are newly prescribed a DOAC. Where the indication for the antiplatelet was primary prevention it should be discontinued to minimise the bleeding risk.

HF and hospital discharges following AHF admission. The months January to August in 2020 were chosen as they corresponded with the first surge of COVID-19 cases internationally and in Ireland, and the period of maximal disruption to chronic HF management in our HFU. During this period, much of our standard HF outpatient management was delivered remotely through our DMP, including nurse-provided weekly calls to post-discharge patients and doctor telephonic consultation to any patient reporting concerning issues. These contacts were complemented by virtual consultation services to the family doctor. In-person consultations with patients were restricted to those with likely HF problems not resolving with telephonic advice and those patients requiring face-to-face review following AHF admission.

The impact of COVID-19 on outcomes for patients with established heart failure (HF) has been limited to the risk of acute heart failure admission (AHF)1, 2, 3, 4, 5 and risk of in-hospital mortality.3 Little if any commentary has been provided on the threat of the pandemic on noncardiovascular outcomes among HF patients and also whether the threat to HF outcomes is different dependent on HF phenotype. Furthermore, observations to date have not been stated to have come from within a disease management programme (DMP), the structure of which could mitigate some of the impact of COVID-19 through remote monitoring.

We undertook a retrospective analysis of hospitalisations and deaths among two sequential HF cohorts attending our HF unit (HFU). Emergency hospitalisation was recorded as AHF, acute cardiovascular but not HF-related (ACV) and non-cardiovascular (ANCV). Elective hospitalisation was noted as cardiovascular (ECV) and non-cardiovascular (ENCV). The first cohort (C1) included all patients who attended the HFU for the first time with a new diagnosis of HF in 2018. Hospitalisation and death rates of this cohort were evaluated in the period January to August 2019. The second cohort (C2) included patients who first attended the HFU in 2019, and the hospitalisation and death rates of this cohort were assessed from January to August 2020. This comparison allowed C1 to act as a form of ‘historical’ control for C2 with patients managed in the same unit. The patient cohorts included new community diagnoses of

to presenting to hospital- most commonly in a HF clinic or GP practice.7 This, and the anecdotal evidence of patients’ reluctance to present directly to hospital during the pandemic, suggests a high likelihood that a significant proportion patients experiencing HF symptoms sought or would seek care within the infrastructure provided by the DMP.
However, in the recently published GUIDE-HF trial a similar reduction in HF event rates was demonstrated during the COVID-19 era, along with a reduction in pulmonary pressures
In the 2020 period (C2) during the first wave of the COVID-19 pandemic, there was a trend to fewer patients admitted for AHF, ANCV, ECV and ENCV in comparison to C1 in 2019, though these findings were not statistically significant. ACV admissions were marginally but not significantly greater in C2 (Fig. 2). In addition, there was a trend to a shorter length of stay for C2 for AHF management (8.6 vs 10 days; p = 0.3).
that COVID-19 can present to HF patients. A possible explanation is that these threats are counterbalanced by access to a DMP, linking dominantly by virtual means. Telephonic remote assessments of patients were complemented by virtual consultations with general practitioners (GPs) to support community management of patients. A previous study from our unit showed that the majority of patients with established HF experiencing an acute decompensation sought a medical assessment in the community prior
Overall mortality was low in each cohort during the time periods analysed with no significant difference found (1.7% in C1 vs. 0.6% in C2, p = 0.137).
We report on the morbidity and mortality risk for HF patients managed within a DMP during the first phase of the COVID-19 pandemic. No increased emergency admission risk was identified across all admission types. In addition, outcomes were similar for the two major HF phenotypes.
Analysis according to HF phenotype demonstrated similar trends in both HFpEF and HFrEF patients. However, HFrEF patients had a trend towards a larger decrease in the relevant admission categories in C2, during the COVID-19 era (Fig. 3).

Patterns of stable-high physical activity were associated with a significantly (52%) lower risk of cardiovascular disease among men compared with those with stable-low patterns.
The greatest benefits seemed to occur at the age of 70. Risk was only marginally lower at the age of 75, and no lower at the age of 80-85, suggesting that improving physical activity earlier in old age might have the most impact, say the researchers.
Initial assessments, including a detailed medical history, physical examination, scans, and a battery of blood tests were carried out between 1995 and 1997, with two further assessments 4 and 7 years later.
have contributed to protecting against ANCV admissions. A trend towards higher ACV admissions in the COVID-19 era was observed, possibly linked to a reduction in ECV admissions allowing issues to graduate to need for emergency care.
At the start of the study, women were more likely than men to have 4+ coexisting conditions, with a higher prevalence of osteoarthritis, osteoporosis, and chronic kidney disease; chronic obstructive pulmonary disease (COPD) and diabetes were more common among the men.

Please refer to Summary of Product Characteristics (SmPC) before prescribing. Entresto® (sacubitril valsartan) 24 mg/26 mg film-coated tablets, 49 mg/51mg film-coated tablets and 97mg/103mg film-coated tablets Presentation: Film-coated tablets of 24 mg/26 mg, 49 mg/51mg and 97 mg/103 mg of sacubitril and valsartan respectively (as sacubitril valsartan sodium salt complex). Indications: In adult patients for treatment of symptomatic chronic heart failure with reduced ejection fraction. Dosage and administration: The recommended starting dose of Entresto is one tablet of 49 mg/51 mg twice daily, doubled at 2-4 weeks to the target dose of one tablet of 97 mg/103 mg twice daily, as tolerated by the patient. In patients not currently taking an ACE inhibitor or an ARB, or taking low doses of these medicinal products, a starting dose of 24 mg/26 mg twice daily and slow dose titration (doubling every 3 - 4 weeks) are recommended. A starting dose of 24 mg/26 mg twice daily should be considered for patients with SBP ≥100 to 110 mmHg, moderate or severe renal impairment (use with caution in severe renal impairment) and moderate hepatic impairment. Do not co-administer with an ACE inhibitor or an ARB. Do not start treatment for at least 36 hours after discontinuing ACE inhibitor therapy. Entresto may be administered with or without food. The tablets must be swallowed with a glass of water. Splitting or crushing the tablets is not recommended. Contraindications: Hypersensitivity to the active substances or to any of the excipients. Concomitant use with ACE inhibitors. Do not administer until 36 hours after discontinuing ACE inhibitor therapy. Known history of angioedema related to previous ACE inhibitor or ARB therapy. Hereditary or idiopathic angioedema. Concomitant use with aliskiren-containing medicinal products in patients with diabetes mellitus or in patients with renal impairment (eGFR <60 ml/min/1.73 m2). Severe hepatic impairment, biliary cirrhosis and cholestasis. Second and third trimesters of pregnancy. Warnings/Precautions: Dual blockade of the renin angiotensin-aldosterone system (RAAS): Combination with an ACE inhibitor is contraindicated due to the increased risk of angioedema. Sacubitril/valsartan must not be initiated until 36 hours after taking the last dose of ACE inhibitor therapy. If treatment with sacubitril/valsartan is stopped, ACE inhibitor therapy must not be initiated until 36 hours after the last dose of sacubitril/valsartan. Combination of sacubitril/valsartan with direct renin inhibitors such as aliskiren is not recommended. Sacubitril/valsartan should not be co-administered with another ARB containing product. Hypotension: Treatment should not be initiated unless SBP is ≥100 mmHg. Patients with SBP <100 mmHg were not studied. Cases of symptomatic hypotension have been reported in patients treated with sacubitril/valsartan during clinical studies, especially in patients ≥65 years old, patients with renal disease and patients with low SBP (<112 mmHg). Blood pressure should be monitored routinely when initiating or during dose titration with sacubitril/valsartan. If hypotension occurs, temporary down-titration or discontinuation of sacubitril/valsartan is recommended. Impaired or worsening renal function: Limited clinical experience in patients with severe renal impairment (estimated GFR <30 ml/min/1.73m2). There is no experience in patients with end-stage renal disease and use of sacubitril/valsartan is not recommended. Use of sacubitril/valsartan may be associated with decreased renal function, and down-titration should be considered in these patients. Hyperkalaemia: Treatment should not be initiated if the serum potassium level is >5.4 mmol/l. Monitoring of serum potassium is recommended, especially in patients who have risk factors such as renal impairment, diabetes mellitus or hypoaldosteronism or who are on a high potassium diet or on mineralocorticoid antagonists. If clinically significant hyperkalaemia occurs, consider adjustment of concomitant medicinal products or temporary down-titration or discontinuation of sacubitril/valsartan. If serum potassium level is >5.4 mmol/l discontinuation should be considered. Angioedema: Angioedema has been reported with sacubitril/valsartan. If angioedema occurs, discontinue sacubitril/valsartan immediately and provide appropriate therapy and monitoring until complete and sustained resolution of signs and symptoms has occurred. Sacubitril/valsartan must not be re-administered. Patients with a prior history of angioedema were not studied. As they may be at higher risk for angioedema, caution is recommended if sacubitril/valsartan is used in these patients. Black patients have an increased susceptibility to develop angioedema. Patients with renal artery stenosis: Caution is required and monitoring of renal function is recommended. Patients with NYHA functional classification IV: Caution should be exercised due to limited clinical experience in this population. Patients with hepatic impairment: There is limited clinical
Safety and tolerability profile similar to ACEi 5,10-12
experience in patients with moderate hepatic impairment (Child Pugh B classification) or with AST/ALT values more than twice the upper limit of the normal range. Caution is therefore recommended in these patients. B-type natriuretic peptide (BNP): BNP is not a suitable biomarker of heart failure in patients treated with sacubitril/valsartan because it is a neprilysin substrate. Psychiatric disorders: hallucinations, paranoia and sleep disorders, in context of psychotic events, have been associated with sacubitril/valsartan use. Consider discontinuation if patient experiences such events. Interactions: Contraindicated with ACE inhibitors, 36 hours washout is required. Use with aliskiren contraindicated in patients with diabetes mellitus or in patients with renal impairment (eGFR <60 ml/min/1.73 m2). Should not be co-administered with another ARB. Use with caution when co-administering sacubitril/ valsartan with statins or PDE5 inhibitors. No clinically relevant drug-drug interaction was observed when simvastatin and sacubitril/valsartan were coadministered. Monitoring serum potassium is recommended if sacubitril/valsartan is co-administered with potassium-sparing diuretics or substances containing potassium (such as heparin). Monitoring renal function is recommended when initiating or modifying treatment in patients on sacubitril/ valsartan who are taking NSAIDs concomitantly. The combination of sacubitril/valsartan and lithium is not recommended. If the combination proves necessary, careful monitoring of serum lithium levels is recommended. Co-administration of sacubitril/valsartan and furosemide reduced Cmax and AUC of furosemide by 50% and 28%, respectively, with reduced urinary excretion of sodium. Co-administration of nitroglycerin and sacubitril/valsartan was associated with a treatment difference of 5 bpm in heart rate compared to the administration of nitroglycerine alone, no dose adjustment is required. Coadministration of sacubitril/valsartan with inhibitors of OATP1B1, OATP1B3, OAT3 (e.g. rifampicin, ciclosporin), OAT1 (e.g. tenofovir, cidofovir) or MRP2 (e.g. ritonavir) may increase the systemic exposure of sacubitril or valsartan. Appropriate care should be exercised. Co-administration of sacubitril/valsartan with metformin reduced both Cmax and AUC of metformin by 23%. When initiating therapy with sacubitril/valsartan in patients receiving metformin, the clinical status of the patient should be evaluated. Fertility, pregnancy and lactation: The use of sacubitril/valsartan is not recommended during the first trimester of pregnancy and is contraindicated during the second and third trimesters of pregnancy. It is not known whether sacubitril/valsartan is excreted in human milk, but components were excreted in the milk of rats. Sacubitril/valsartan is not recommended during breast-feeding. A decision should be made whether to abstain from breast-feeding or to discontinue sacubitril/valsartan while breast-feeding, taking into account the importance of sacubitril/ valsartan to the mother. No available data on the effect of sacubitril/valsartan on human fertility. Undesirable effects: Very common: Hyperkalaemia, hypotension, renal impairment. Common: Anaemia, hypokalaemia, hypoglycaemia, dizziness, headache, syncope, vertigo, orthostatic hypotension, cough, diarrhoea, nausea, gastritis, renal failure, acute renal failure, fatigue, asthenia. Uncommon:Hypersensitivity, postural dizziness, pruritus, rash, angioedema. Rare: Hallucinations, sleep disorders. Very rare: Paranoia.

This research is based in part on a final year dissertation for the taught MSc Digital Health course offered by UCC. The title of the research was: Exploring clinicians’ perspectives on the current Venous Thromboembolism risk assessment practices in Cork University Hospital and their acceptability towards an e-learning platform for VTE risk assessments in the future. The second stage of this project now works in collaboration between the Haematology Dept. (Dr Maeve Crowley) in CUH and the Cork University Business School, UCC (Dr Wendy Rowan). The original research was qualitative in nature and aimed at understanding the clinician’s experience of VTE risk and completing the risk assessment in CUH (Image shows some feedback from clinicians). There was a desire to understand if clinicians felt there was more training needed and if so, what would this training look like. After analysing the qualitative data using thematic analysis, the development of a VTE risk assessment video was identified as a need and different elements within the video design were categorised in relation to clinical motivators to prompt and remind clinicians to complete the VTE risk assessment.

An aneurysm is defined as a dilatation of more than 1.5 times the size of the normal aorta. In cases of aortic aneurysm, approximately 60% occurs in the Root/Ascending aorta, 10% in the arch, 40% in the descending aorta, and 10% in the thoracoabdominal aorta; however, an aneurysm may involve multiple aortic segments. Very rarely, the aneurysmal process can involve the whole aorta; from aortic root to the iliac Thoracicbifurcation.aortic aneurysms are asymptomatic in more than 95% of cases until diagnosed. The annual incidence of TAAs has been assessed at 6 to 10 cases/100,000 patient-years. Interestingly, the incidence of TAAs appears to be increasing, most probably due to an aging population and more frequent imaging.
Natural history of aortic aneurysms
It is important to consider bicuspid aortic valve when discussing aortic Theaneurysm.incidence of aortic dilation and acute complications (rupture and dissection) is higher in patients with BAV.

F. Family history
The normal aorta expands by 0.9mm/10 years in male and 0.7mm/10 years in female.
An understanding of the anatomy of the proximal aorta is essential when considering aortic Theaneurysms.proximal aorta is divided into several segments (Figure 1):

The main complications of an enlarging aortic aneurysm are: Aortic dissection and Aortic rupture, both of which can be fatal. Other complications would include mass effect on adjacent structures (e.g. tracheal compression) and aortic valve regurgitation due to stretching of the valve commissural posts.

Proximal aortic aneurysms
The most common types of leaflet fusions are Right/Left fusion (70%), Right/Non-Coronary fusion (10-20%) and Left/Non-Coronary fusion (5-10%).
Bicuspid aortic valve (BAV) is the most common congenital heart defect, affection around 1.4% of the population. BAV is a highly heritable trait, but the genetic causes remain largely elusive. NOTCH1 is the only proven candidate gene to be associated with BAV.
BAV are classified according to Siever’s Classification (Figure 4):
The combination of aortic coarctation and BAV is assumed to be associated with a higher risk of ascending aortic dilatation and dissection, and current European Society of Cardiology (ESC) guidelines advise therefore to operate at a lower threshold in the presence of a coarctation in BAV patients.
shows a 4-D flow MRI indicating the wall stress with bicuspid R/L fusion compared to a trileaflet aortic valve.
As mentioned, the vast majority of aortic aneurysms are clinically silent. Most aneurysms are incidentally diagnosed clinically, whether it is on a chest X-ray or CT scan done for another indication. Aortic aneurysms can also be incidentally picked up on echocardiogram. However, the smaller field of view with echocardiogram usually limits the diagnosis to the aortic root and ascending aorta only.
The gold standard diagnostic tool for aortic aneurysms remains a CT aortogram with contrast. A gated CT scan is preferred to avoid motion artefact at the aortic root for accurate measurements.
A Right/Left fusion tend to generate a right-handed helical flow in the aorta, resulting in dilatation of the Ascending +/Root of the aorta. A Right/NonCoronary fusion generates a lefthanded helical flow which almost always only result in the dilation of the ascending aorta. Figure 5

Diagnosis of aortic aneurysms
BAV has only 2 leaflets (functional or anatomical) as compared to the three leaflets of a normal aortic valve (Figure 3).
Patients with aortic disease usually require life-long surveillance, regardless of the initial treatment strategy (medical or surgical).
The researchers go on to suggest that this updated information should be communicated to patients through informed clinical decision-making and updated clinical guidelines and policy. This important discovery was a collaboration with Professor Susan M Smith, also of RCSI and with researchers from the University of New Mexico, USA, (Dr Robert DuBroff), the Institute for Scientific Freedom in Denmark (Dr Maryanne Demasi), Bond University in Australia (Dr Mark Jones) and independent researcher Dr Kirsty O’Brien.
risk factors, such as family history, systemic hypertension, coarctation of the aorta, or rapid increase in rate of expansion.
Surgical Intervention
Isometric exercise with a high static load (e.g. weightlifting) should be discouraged.
The lead author on the paper is Dr Paula Byrne from the HRB Centre for Primary Care Research based in RCSI’s Department of General Practice. Commenting on the findings, Dr Byrne said: “The message has long been that lowering your cholesterol will reduce your risk of heart disease, and that statins help to achieve this. However, our research indicates that, in reality, the benefits of taking statins are varied and can be quite modest.”
The type and extent of surgery will depend on which segments of the aorta are involved. Surgery for thoracic aortic aneurysm can range from a simple interposition graft to more complex procedures such as aortic root replacements, arch replacements and Frozen elephant trunk procedures (Figure 6)
In patients with aneurysm that have yet to reach threshold for surgical intervention, surveillance is particularly important to monitor rate of expansion of the aneurysm and plan surgical intervention to avoid any potential dissection or rupture. In patients who had surgery, it is important to monitor the remaining segments of aorta over time, as it is not uncommon for these patients to develop aneurysmal segments of the remaining native aortic segments over time. We have recently set up a surveillance clinic dedicated for proximal aortic aneurysms here at St James’s Hospital.

Generally speaking, in patients with no elastopathy, surgery should be considered for ascending aorta/root/arch aneurysms measuring 55mm or more. In patients with connective tissue disorders such as Marfan’s, a lower threshold of 50mm is generally indicated. If high risk factors are present along with Marfan’s, surgery is indicated at a size threshold of >45mm.

prevention strategies must be similar to those indicated for the above diseases. To prevent blood pressure spikes, competitive sports should be avoided in patients with an enlarged aorta.

Surgical intervention provides definitive repair of the aneurysmal aortic segment. The main principle
The new findings contradict this theory, finding that this relationship was not as strong as previously thought. Instead, the research demonstrates that lowering LDL-C using statins had an inconsistent and inconclusive impact on CVD outcomes such as myocardial infarction (MI), stoke, and all-cause mortality.
and this is reflected in the various iterations of expert guidelines for the prevention of CVD. Statins are now commonly prescribed by doctors, with one third of Irish adults over the age of 50 taking statins, according to previous research.
Other than absolute size, other factors such as connective tissue disease, rate of expansion, family history, concomitant aortic valve surgery and symptoms are important to consider when deciding the timing of surgery.
Indications for surgical intervention
Surveillance
New research from RCSI University of Medicine and Health Sciences has revealed that the link between ‘bad’ cholesterol (LDL-C) and poor health outcomes, such as heart attack and stroke, may not be as strong as previously thought.
In addition, it indicates that the overall benefit of taking statins may be small and will vary depending on an individual’s personal risk factors.
Published in JAMA Internal Medicine, the research questions the efficacy of statins when prescribed with the aim of lowering LDL-C and therefore reducing the risk of cardiovascular disease
of surgery is to prevent aortic dissection or risk of rupture by replacing the aneurysmal aorta and restoring the aortic dimensions back to normal.
Indications for surgery are based mainly on the aortic dimensions and derived from findings on natural history regarding the risk of complications weighed against the risk of elective surgery.
In patients undergoing aortic valve surgery who also have a dilated aorta, the aorta is replaced as well if the diameter is >45mm.
Heart News
In bicuspid valve patients, surgery should be performed when the maximal aortic diameter is ≥55 mm; these face a lower risk of complications than in Marfan’s patients. A lower threshold of 50 mm can be considered in bicuspid patients with additional

In patients with HF, the treatment goals are to reduce mortality, improve clinical status, improve quality of life (QoL) and prevent hospital admissions.2 In 2021, the European Society of Cardiology (ESC) released the latest guidelines for the diagnosis and treatment of acute and chronic HF.3 New concepts and recommendations make the 2021 guidelines a significant step forward from the previous ESC guidelines released in 2016.4 From a Pharmacist’s perspective, the following points are of particular interest:
• EMPEROR-Reduced: Empagliflozin Outcome Trial in Patients with Chronic Heart Failure and a Reduced Ejection Fraction.9
Reduced trial which prospectively evaluated the efficacy and safety of empagliflozin in patients with HFrEF, regardless of the presence or absence of diabetes showed a 24% reduction of the primary outcome, which was a composite of death from cardiovascular causes or hospitalization for worsening HF in patients treated with empagliflozin in addition to standard treatment, compared to standard treatment and placebo.9
I. The introduction of new terminology for HF classification. HF with midrange ventricular Ejection Fraction (EF) has been renamed in the 2021 HF guidelines as ‘HF with mildly reduced EF’ (HFmrEF) when EF is between 41-49%. This change in terminology was supported by the evidence gained in HF Randomised Control Trials (RCTs) that showed how patients with EF 41-49% benefited from similar treatment to patients with EF<40.5
The DAPA-HF trial which prospectively evaluated the efficacy and safety of dapagliflozin in patients with HFrEF, regardless of the presence or absence of diabetes, showed a 26% reduction of the primary outcome. The primary outcome was a composite of worsening HF or death from cardiovascular causes in patient treated with dapagliflozin in addition to standard treatment, compared to placebo and standard treatment.8 The EMPEROR-
Now that these new evidencebased HF treatments have become a fundamental part of the GDMT, it is important/ imperative that healthcare professionals adopt the use of these medications in their practice to improve outcomes for HF patients.
The new evidence- based treatment options: the ARNI (in place of ACEi or ARBs) and SGLT2 inhibitors are now available for the optimal management of patients with HF. These agents have proven to help reduce hospitalization and mortality in patients with HF. In addition to β- blockers and mineralocorticoid receptor antagonists, ARNI and SGLT2 inhibitors have become a fundamental part of the Guideline-Directed Medical Therapy (GDMT) for HF.

This is an area that warrants targeted research.

While there is no defined clinical criteria for the diagnosis of cardioembolic stroke, the clinical approach should include a detailed history, clinical exam, neuroimaging, ECG and, importantly, echocardiography. Inpatient telemetry can be used to diagnose paroxysmal atrial fibrillation. Prolonged monitoring with outpatient holter monitors are recommended if suspicion remains for a cardioembolic source. Longer automated cardiac monitoring has been shown to be useful in detecting paroxysmal AF- even a 30-day recording can improve AF detection rates 5-fold (EMBRACE trial).

Many cardiac disorders are recognised as potential sources of embolism- atrial fibrillation (AF) remains the most significant. It’s the most common sustained arrythmia, with its prevalence increasing in the older person. It is recognised as precipitating 50% of cases of cardioembolic strokethis may be preventable with early identification and treatment. The CHADS2VASC score can be used to predict the risk of ischaemic stroke in patients with AF.
Valvular disease, including mechanical valves, also carry a high risk of embolic events and while the incidence of rheumatic mitral valve disease has decreased in recent times, it still carries a significant burden of disease in endemic and developing regions. Embolism should also be a consideration in infective endocarditis. While infective endocarditis is itself a relatively uncommon, it’s important to note that 20% of cases of endocarditis with intracardiac vegetations are complicated by embolic stroke, with the mitral valve the most frequent source of emboli. Prompt antibiotic therapy typically reduces this potential.

While atrial fibrillation is the leading cause of cardioembolic stroke, it is important to recognise other potential cardiac sources of embolism such as chamber dysfunction, valvular disease or a mechanical prosthetic valve, and infectious aetiologies like endocarditis. Myocardial infarction (MI) can lead to left ventricular dysfunction and focal areas of dyskinesia. This can result in stasis and formation of mural thrombi, leaving these patients at high risk of embolic stroke. Acute MI is considered aetiological if stroke occurs within one month of the MI.
Stroke remains a leading cause of death and disability globally. While 10-15% of strokes are haemorrhagic in nature, ischaemic stroke, due to thrombosis, embolism or systemic hypoperfusion, accounts for over 80% of cases. Acute ischaemic strokes are time sensitive due to the reperfusion treatments like thrombolysis and thrombectomy. Accurately identifying stroke mechanism is important as it allows for evidence based recommendations for therapy and developing future preventative strategies. The TOAST classification is commonly used in stroke research and subdivides ischaemic stroke into 5 categories - a) large artery atherosclerosis, b) cardioembolism, c) small vessel occlusion, d) stroke of other determined aetiology and, e) stroke of undetermined aetiology (cryptogenic).
In 2014, the term “embolic stroke of undetermined source” (ESUS) was introduced as a subset of cryptogenic strokes for patients with non-lacunar strokes and no identifiable mechanism. The most prevalent source of emboli is thought to remain cardiac. Although initially AF was

Anxiety, depression and insomnia disorder affect approximately one-third of people with CVD, and up to one in four cardiac patients experience clinically significant levels of posttraumatic stress (PTSD)1-4. Furthermore, psychological distress is linked to increased future cardiac events and mortality, poorer quality of life, increased suicide risk, greater healthcare costs and poorer long-term psychological adjustment5. Unfortunately, there is also evidence that during the COVID-19 pandemic psychological distress has increased in cardiac patients and this has been exacerbated by social isolation, treatment nonadherence, physical inactivity, and an increase in unhealthy lifestyle behaviours6,7

Meeting of Hearts & Minds – The Practice of Cardiac Psychology
In the initial aftermath of a cardiac event, the focus is understandably on the patient’s physical recovery, and many people feel relief or even gratitude for having survived. However, once a person begins to feel better physically, the emotional distress they have been holding at bay can surface. It may feel safer for this to emerge after things appear to have stabilised medically. Although this can be a normal part of the recovery process it can be quite frightening if the person hasn’t experienced this kind of emotional vulnerability previously.

People may feel anger if they believe their cardiac issue was not identified in time, or even towards others (e.g. employer, family members) whom they perceive to have contributed to their high stress
Some people may even feel traumatised by their cardiac event. For example, if they nearly died or were shocked on the way to hospital; or if their implantable device (ICD) went off. Or maybe they were very distressed in ICU and were convinced they were going to die. Sometimes in the aftermath of such an experience people develop symptoms of posttraumatic stress disorder (PTSD) which can include reliving the trauma or having flashbacks or nightmares, feeling very alert to future risk and feeling very anxious. These symptoms often resolve but at times can remain very frightening.

Social isolation and/or lack of perceived support can deepen the impact of depressed mood.
Mental and behavioural habits that perpetuate the stress cycles people are caught in can add additional suffering and impede physical recovery. For example, people often need help getting unstuck from thinking traps that drive automatic or unhelpful behaviour. This may include guilt about previous lifestyle choices made, regrets, self-blame or self-criticism. These common thinking styles can hold people back and lower mood, particularly in those patients who had a lot of negative selftalk before their cardiac event.

The psychological benefits of exercise training (ET) are wellestablished14 and ET is proven to be a highly cost-effective intervention for improving depressed mood in cardiac patients15. This can be particularly effective when allied to the social support received by staff and/or peers during CR. However, international guidelines continue to recommend that comprehensive
Relationships and sexual health are also significantly impacted in the aftermath of a cardiac diagnosis and individuals need to feel confident in having a safe space to speak openly about these important concerns should they need to.
In the case of individual therapy (e.g. anxiety, depression, adjusting to adverse life events) the intention in exploring psychological distress is to allow its expression, to acknowledge it, and to offer the patient treatment strategies to address stress and factors currently contributing to the distress. A concurrent aim can be to focus on aspects of life that are meaningful that can be expanded upon, particularly in the case of existential difficulties experienced following a near death
All patients are invited to attend weekly small group psychoeducational sessions which are incorporated into the CR programme. These sessions are based on a CBT framework and address adjustment to heart disease, health related lifestyle changes, and adaptive coping. Additional group sessions address sleep, weight management, managing depressed mood, stress and heart disease, overwork & exhaustion, treatment adherence, the psychology of eating and resuming sexual activity after a cardiac event.
The mind and body are inextricably linked, and psychological well-being has direct effects that mediate improvements in cardiovascular health. Better psychological well-being is associated with lower blood pressure, a lower prevalence of metabolic syndrome, a more favourable lipid profile, a lower likelihood of smoking, increased exercise levels and greater adherence to a hearthealthy diet9-11. Conversely, anxiety and chronic stress have been shown to increase inflammation, increase blood pressure and stress hormones such as cortisol which can impact coronary arteries and increase the risk of cardiac events. Similarly, depression has also been shown to be linked with increased inflammation, reduced physical activity, continued smoking, weight gain and poorer adherence to secondary preventive medications (SPMs). While psychological components are clearly linked with both health behaviours and factors that are directly related to cardiovascular health, improving the psychological wellbeing of cardiac patients is key to optimising their health outcomes.
Additionalexperience.expertise provided by cardiac psychologists includes psychological preparation for cardiac surgery, weight management, psychosexual counselling, insomnia treatment, medication adherence, family support (e.g. caregiver burden in heart failure), neuropsychological assessment, maintaining lifestyle changes, training of cardiology team members, research, clinical audit and quality improvement, and advocacy.
During CR, all patients routinely meet with the cardiac psychologist at the beginning of the programme, and this enables timely identification of patients at increased risk of psychological difficulties. As well as affording each patient the time and space to tell their individual story, patients identify the role of the psychologist as an integral component of CR. This normalises the inclusion of psychological issues in cardiac care and ensures high levels of patient engagement.

Stress management training (SMT) - when fully integrated with CR - not only helps patients to reduce stress but is proven to deliver an incremental benefit on cardiac outcomes (e.g. recurrent events, hospital readmissions) when compared to CR alone. Similarly, many psychologists are also trained in the delivery of mindfulness-based interventions (MBI) which can help CR patients to learn an effective coping strategy for managing stress and a way of

PSYCHOLOGICAL CARE FOR CARDIAC PATIENTS DURING CARDIAC REHABILITATION (CR)
From a psychological standpoint, cardiac patients experiencing psychological difficulties present to CR in broadly two different ways: their distress is ‘new’ following their recent cardiac event; or they’ve had ongoing stress prior to their health issues which is now adding to their current distress (e.g. health anxiety). Many of these patients also have other psychological and behavioural problems and have never encountered a mental health professional

a process of recovery where patients grow together in their confidence to re-engage with their lives after a cardiac event. Because they are monitored during exercise, they feel safe to push themselves physically and this helps them to restore a sense of trust in their bodies and the expectation that they will recover well This process is reinforced by targeted education on behavioural risk factors (e.g. diet, medications, smoking) which enhances the patient’s understanding of their heart condition and their sense of control over their health. The group context has a normalising effect as it enables people to share their experiences with others. This allows patients to both benefit from the support of their peers and to learn that they are not the “only ones” to feel this way. CR can also be a good time for people to pause and re-evaluate what’s important to them in life and where they wish to spend their time and attention going forward. Cardiac patients are often acutely aware of the opportunity to review and improve their quality of life that is not afforded to those who die suddenly. This can sometimes come to be seen as a ‘silver lining’ that accompanies a recent realisation of life’s fragility.

CR programmes also provide psychological interventions delivered by appropriately trained mental health professionals, and that patients with psychological difficulties are followed in a stepped manner through to remission16-18 Psychologists working in CR provide a range of psychological treatments to meet the needs of cardiac patients. Where possible, a matched or stepped care model is employed allowing treatment complexity to be matched to patient need. This allows for simpler low-intensity psychological interventions initially but also provides for specialist mental health care to be available to those patients requiring it. This model has been shown to be both accessible to patients and associated with increased satisfaction with cardiac care19

CR is a comprehensive, multi-disciplinary chronic disease management programme that incorporates core components such as patient assessment, supervised exercise training with continuous ECG monitoring (telemetry), nutritional counselling, management of cardiac risk factors (lipids, diabetes, blood pressure, weight) and psychological management. To ensure comprehensive cardiac care, some CR programmes have a psychologist on staff as a fully integrated member of the MDT.

For sensitive treatment-related issues (e.g. erectile dysfunction), a referral to the cardiology clinic is facilitated on the patient’s behalf. Psychological support is also provided to partners of patients where appropriate.
During the same 6-month period, 24 patients were seen for individual therapy sessions, and the average number of sessions received by patients was 4 (range 1 – 8 sessions). Areas of distress that were explored frequently included anxiety and depression and difficulties with adjustment to the cardiac event. In addition stress management, social and relationship difficulties were also addressed.
In the Mater Hospital Cardiac Rehabilitation programme (CR) there is a principal clinical psychologist (WTE 0.4) appointed to the 8-week programme. All patients are invited to the 2-hour stress management talk given by the psychologist. During this talk, all patients are invited to take part in a mindfulness exercise and are then invited to participate in an 8-week mindfulness group. Mindfulness-based interventions (MBI) have been associated with improvements across a range of physical and mental health outcomes, including improved depressive symptoms, anxiety, stress, quality of life, smoking cessation, healthy eating and physical activity25-27. In line with these findings, evaluations of MMUH groups have demonstrated
As we have seen, psychological factors are strongly linked with cardiac prognosis, and there is firm evidence underpinning psychological support for patients with heart disease. Furthermore, the need for psychological support has intensified during the recent pandemic. However, psychological services for cardiac patients in Ireland are poorly resourced nationally and characterised by inequitable access.
The recent National Survey of CR services28 conducted by Irish Heart Foundation (IHF) and the Irish Association of Cardiac Rehabilitation (IACR) showed that 80% (28/35) of CR centres had no access to psychological support for their patients. Yet, access to psychology was the highest rated service required (50% of CR Centres) to improve the quality of CR. Similarly, the IHF have deemed psychology a priority area and added: “the lack of psychological services and supports is emerging as one of the issues of greatest concern to the people in our patient advocacy network”

Beaumont Hospital have also developed a comprehensive Heart Failure Self-Management Programme to support patients living with HF, including those unable to participate in exercisebased CR. The ‘UPBEAT’ programme targets the health of both patients and their caregivers (e.g. caregiver burden) and has been shown to be effective in improving HF self-management, psychological distress and medication adherence in patients living with HF.
CR programme can benefit from two psycho-educational group sessions where participants learn about stress, depression, how these difficulties can impact heart health, coping strategies and signposting to further help, and planning for post-CR behaviour maintenance. Mindfulness based interventions (MBI) such as mindfulness-based stress reduction (MBSR) and mindfulness based cognitive therapy (MBCT) are 8-week group interventions run by the SVUH Psychology Department and are also available to these patients. MBI have been shown to reduce stress, depression, improve quality of life and help individuals manage ongoing chronic conditions23
As well as direct clinical work with patients, SVUH’s Cardiac Psychology service collaborate with colleagues in other settings (e.g. the Irish Heart Foundation) to highlight the psychological needs of cardiac patients and to advocate for optimum service provision. Research and the provision of training to colleagues which is cognisant of the psychological needs of patients is also core business of the service.
CR programmes in Ireland are anxious to provide their patients with access to this essential service. The multidisciplinary team (MDT) for each CR centre should include dedicated and adequate psychology staffing. Our patients deserve nothing less.
The Cardiac Psychology service at SVUH has evolved over time and currently employs both a senior clinical psychologist (1.0 WTE) and a psychotherapist (0.3 WTE). SVUH also provide a stepped care model delivering a service for patients across the spectrum of cardiac disease.
Lower intensity and group-based interventions are offered for mild to moderate distress, and higher intensity interventions (e.g. individual psychological therapy) are offered where there is greater complexity to the presenting difficulties and more severe distress.

All patients completing the CR programme are also followed up by the cardiac psychologist. For patients requiring additional support at this point, treatment options are discussed with the patient and onward referrals are made as appropriate (e.g. referral for stress management, individual therapy, GP, community mental health team and/or Irish Heart Foundation patient support group).

As part of Beaumont’s steppedcare pathway, patients can also access a comprehensive Stress Management Training (SMT) Programme specifically designed for cardiac patients. This multicomponent intervention combines psychoeducation, group support and cognitive behaviour therapy for groups of 10-12 patients. Here patients acquire an extensive repertoire of relaxation techniques and psychological skills targeting stress, anxiety, sleep and anger/hostility.
Patients living with heart failure (HF) are at increased risk of psychological problems such as depression and anxiety, which can in turn negatively impact cardiac outcomes. Patients with HF can access SVUH’s Cardiac Psychology service at different stages of their illness from diagnosis to episodes of acute decompensated HF, disease progression through to end of life. CR is proven to be effective with this patient population, and the Cardiac Psychology Service also contribute to the 8-week multidisciplinary CR programme for patients with HF. A clinic also runs from the Heart Failure Unit offering individual therapy for those with more moderate to severe distress. MBI is a helpful follow-on for those appropriate who are discharged from CR or individual therapy, and patients with HF are accepted to this programme.
this to be an effective coping strategy for CR patients in terms of reducing anxiety and depression.
Patients with arrhythmias or an implantable cardiac device attending SVUH can also avail of the Cardiac Psychology service. Although most patients receiving an implantable cardioverter defibrillator (ICD) or pacemaker adjust without psychological difficulties, a significant proportion of patients can experience specific psychological challenges. Some patients with an ICD can develop problems with body image due to the implant, or anxiety in response to either cardiac symptoms or due to the device delivering therapy (i.e. an electric shock). Some will develop post-traumatic stress problems such as hypervigilance or feeling on edge, avoiding things that cause distress or re-living distressing experiences (e.g. nightmares). Notably, the prevalence of PTSD in patients with an ICD has been shown to be greater than that for Gulf War veterans24. The Cardiac Psychology service contribute to a multidisciplinary group education session for those who have been recently fitted with a device to help support patients’ awareness and independent selfcare. In addition, psychological therapy, in particular CBT and trauma-informed cognitive therapy are available to patients requiring individual support.
A pre-pandemic snapshot of the Cardiac Psychology service over 6 months showed that approximately 65 patients attended the stress management talk at the beginning of CR, and just over half of these patients (33) went onto to attend one of the 2 mindfulness groups run during this time. Feedback from the evaluation of the mindfulness programme has shown that patients viewed this an effective method to both manage stress and approach psychological distress differently. Additionally, patients indicated some improvements in mindfulness skills and self-compassion.
Additional group sessions address sleep, weight management, managing depressed mood, stress and heart disease, overwork & exhaustion, treatment adherence, the psychology of eating and resuming sexual activity after a cardiac event.
The earliest recorded description of pacing was in 1882 and its now over 60 years since the first patients received an implantable cardiac pacemaker. Many lives have been saved and quality of life improved by these early devices and the many subsequent developments implemented over the following decades. Important developments include the implantable cardioverter defibrillator (ICD) in 1980 and then more recently a treatment for heart failure with cardiac resynchronisation therapy (CRT), first described in 1984 followed by the development in recent years of conduction system pacing (CSP).

Current pacemakers and defibrillators are capable of largely functioning autonomously. Automatic threshold testing reducing battery depletion, detection of arrythmia such as atrial fibrillation and longevity monitoring are just three of the advantages of remote monitoring. Particularly during the COVID era the ability to monitor patients safely remotely has been invaluable. Over the coming years this will likely continue to expand and lead to less frequent attendance for patients in person within traditional pacing clinics. Early devices required a specific ‘transmitter’ to be present near the patient, usually left at home to send data to the device company. Newer devices connect to a patients mobile phone through an app from the device company allowing almost continuous connection to the remote monitoring data server. Integration of other biometric data

Pacing Developments
Pacemakers are indicated for symptomatic bradycardia and also in cases of atrio-ventricular (AV) block for improving prognosis. In the main cardiac resynchronisation pacemakers are indicated in patients who develop significant intraventricular conduction delay (bundle branch block) or those with left ventricular (LV) impairment who are expected to receive a high degree or percentage of heart beats activated from conventional right ventricular (RV) pacing. Right ventricular pacing is associated with the development of LV impairment (pacing induced cardiomyopathy) and has been shown to increase mortality. Particularly at risk are those with pre-existing LV impairment. Approximately 10-20% of patients with normal LV function will develop LV

impairment following significant RV pacing (>40% ventricularly paced beats). ICDs were originally inserted for survivors of cardiac arrest (secondary prevention implantation) but it has become apparent that high risk patients could be identified prior to sudden cardiac death (primary prevention implantation). Current practice is therefore to insert the majority of ICDs for those judged to be at high risk of ventricular arrhythmia as a primary prevention measure. However the prediction of sudden death risk remains challenging although this has been assisted greatly by developments in a number of clinical areas including for example, imaging with cardiac MRI to image myocardial fibrosis and in some specific cardiomyopathies, genetic testing.

dose pre-implantation intravenous antibiotics, normothermia and normoglycaemia have helped minimise infection risk. Further developments have allowed many device procedures to be performed without interrupting anticoagulation reducing the risk of stroke related to withholding anticoagulants. Without the use of diathermy or other haemostasis technique the development of a post procedure haematoma carries a significant increased risk of infection.

MRI conditional devices have become an industry standard across almost all devices from basic pacemakers to defibrillators. Large studies have shown there is no issue in patients who have defibrillators deactivated during scanning. Patients however still require attendance for a pacing check usually immediately preceding and following their MRI to ensure the device is functioning appropriately and safely. FOCUS: PACING
In specific patients the inducibility of sustained ventricular arrhythmia by electrophysiology testing (ventricular pacing) may be used to help guide a decision of defibrillator insertion for a specific patient.
Over a number of years battery developments have resulted in both smaller device sizes and also in longer device longevity. This will reduce the frequency of generator changes and the potential complications of such procedures such as infection.
The demand for bradycardia pacing in an ageing population is growing rapidly. An important development has been the recognition of the deleterious effects of a high burden of ventricular pacing. Focus on reducing the risks of these patients developing heart failure from a pacing induced cardiomyopathy has been on software algorithms and more recently techniques to utilise pacing of the patients own conduction tissue. This technique is known as conduction system pacing (CSP) and includes His bundle pacing to target the atrioventricular node and more recently left bundle branch pacing from a lead inserted across the interventricular septum.
Modern imaging techniques such as cardiac MRI (CMR) to assess ventricular function and fibrosis within the mid ventricular wall is also a risk factor for sudden cardiac death in some conditions.
Advances is lead implantation techniques and hardware advances including delivery systems and modern quadripolar (vs. bipolar) pacing leads has permitted very high implant rates and avoiding complications such as diaphragm pacing from inadvertent phrenic nerve capture. Improved venous access techniques using intraprocedural ultrasound, venoplasty and balloon dilatation of peripheral and central veins including the superior vena cava have increased procedural success rates and reduced indications for epicardial pacing leads usually applied via an invasive thoracotomy.

Developments in bradycardia pacing
The majority of patients receiving an internal defibrillator have a diagnosis of cardiomyopathyischaemicordilated (non ischaemic) cardiomyopathy. Most patients have a primary prevention indication, mainly determined by left ventricular ejection fraction in most conditions. Secondary prevention patients may have had a sustained arrythmia or resuscitated from a cardiac arrest and are also indicated to receive a device in most cases.
Software innovations to optimise the fusion of intrinsic cardiac conduction, through the AV node and native cardiac conduction tissue and pacing, largely from the left ventricular lead appears to be beneficial. Investigations are ongoing into whether mutlitipoint
There is a choice of subcutaneous or conventional transvenous internal defibrillators. Most patients receive transvenous systems which can provide ATP (anti tachycardia pacing) to overdrive and terminate a ventricular arrythmia thereby not requiring a device shock or defibrillation. Subcutaneous defibrillators using a lead underneath the skin and not within the vascular system have been shown to be effective and safe, they are able to discriminate between normal rhythms and ventricular tachycardia. Without a transvenous lead within the heart they utilise a surface electrocardiogram (ECG) created between the lead and the defibrillator device instead to detect abnormal rhythms requiring treatment.
pacing only and devices that are integrated to provide both atrial and ventricular pacing using Bluetooth communication between the devices.
Further developments have included leadless pacemakers implanted into the right ventricle. Initially these have been single chamber, ventricular pacing and sensing only devices but more recently an atrial sensing device utilising motion detection of the device corresponding with atrial contraction has become available. Undergoing further clinical evaluation are leadless pacemakers specially for atrial
Biventricular pacing to provide cardiac resynchronisation therapy was first described over 25 years ago. CRT has been extensively proven to be one of the most clinically and cost effective cardiovascular therapies in terms of reductions in mortality and heart failure (HF) hospitalisation. Critical to decision making for a patients suitability for this therapy is the presence of electrical conduction delay (bundle branch block) across the heart assessed by the surface ECG QRS duration and pattern, alongside significant LV systolic impairment, ejection fraction <35% in patients receiving optimal heart failure therapy.
Cardiac resynchronisation therapy (CRT)
However CRT should also be considered for an additional group of patients who are predicted to receive a high degree of right ventricular pacing and who have left ventricular impairment, which is likely to worsen with RV apical pacing. Therefore for a patient requiring a pacemaker in the setting of complete or high grade AV block with reduced LV function should be considered for a CRT device to prevent a deterioration in ventricular function from pacing alone.
Ensuring >92% of heart beats are from CRT is vital, patients with frequent ventricular ectopics or atrial fibrillation require medication alteration, ectopic focus ablation or AV nodal ablation in some to increase the percentage of CRT ventricular pacing therapy, is proven to improve outcomes including reducing mortality.

some patients the risks may be significant. Therefore procedures to implant pacing devices either epicardially (thoracoscopically) or endocardially from arterial access retrogradely across the aortic have are possible. One such system uses ‘induction pacing’ with a transmitter inserted initially very similar to a standard pacemaker generator subcutaneously. Followed by the insertion of a pacing ‘seed’ within the left ventricular cavity to pace the myocardium. Thereby avoiding the necessity of venous access to pace the left ventricle and achieve cardiac resynchronisation by biventricular pacing if this pacing ‘seed’ is implanted in the left ventricular free wall.
• Higher risk of occlusion (thrombus or venous stricture of the vein or damage to heart structures)
and therefore reduced battery longevity. A new development of pacing the left bundle branch of the His Purkinjie system, transeptally appears to overcome these issues. So far the technique has been shown to be reproducible, teachable and lower thresholds on these very stable leads in the medium term. Studies in patients undergoing LBBp lead insertion in the setting of heart failure also suggests a response in ejection fraction superior to conventional CRT. This technique of implantation of a pacing lead within the ventricular septum may be combined with conventional left ventricular lead pacing via the coronary sinus (LOT-CRT). Potentially overcoming some of the limitations in resynchronisation of patients with intraventricular conduction delay (within the ventricular conducntion tissue) with conventional techniques. Our own research is assessing this technique against conventional CRT devices, in particular its safety and the learning curve for lead implantation against conventional biventricular pacing.
• More complex future lead extraction (removal)
APRIL 2022 • HPN | HOSPITALPROFESSIONALNEWS.IE 56
• Higher risk of future device infection
However if additional leads are added without removing an old lead (extraction) the procedural risks of extraction are avoided but the old leads can increase the risk of future complications:
Extraction of failed leads that may have fractured or require removal due to infection is also an increasing requirement for any device service. Techniques and equipment have evolved significantly to improve both the success of extraction of leads in their entirety as well as the safety of the procedure. Although this complex procedure still requires specific training and competency there is also a requirement for a cardiac surgical back up team in case of emergency. Leads that have been in situ for many years (> 10 years), and in particular specific leads such as dual coil defibrillator leads with a high voltage coil within the superior vena cava or specific lead models known to fragment resulting in significant scar tissue in growth require careful pre procedural planning and consideration of ‘hybrid’ techniques. Hybrid extraction includes not only removing the lead(s) required from the site of venous entry of the lead(s) but the assistance of snaring the lead as well to provide counter traction either from a superior jugular vein of inferiorly from the inferior vena cava. Despite these developments lead extraction remains challenging and with significant risks and is therefore performed in specific centres like ours with appropriate expertise. However in published studies high volume operators show clinical success rates of around 98% for successful lead removal. The risk of internal bleeding, cardiac tamponade or haemothorax among other risks is 0.5%. With an ageing population, improvements in heart failure managment and increasing implantation indications it is inevitable that we will see a rapid increase in all device related procedures over coming years.

pacing from a quadripolar left ventricular pacing lead provides benefits that overcome the inevitable battery drain of pacing from more than one site.
There has been concern that pacing leads inserted into the fibrous His bundle region at the AV node have higher thresholds
Many patients require a number of pacing procedures throughout their lifetime. Both through the failure of the leads inserted at their initial implant procedure but also over time if upgrading to more complex systems such as resynchronisation is required. In some cases venous access may also be blocked or narrowed necessitating the use of techniques such as venoplasty to dilate narrowed veins to permit venous access. This may also necessitate the removal of a non functional or previously abandoned lead(s) by extraction of the lead but using this ‘channel’ to pass a wire simultaneously to maintain access for a new lead to be inserted.
For some patients often due to the presence of previous leads and potentially occlusion of the superior vena cava access for leads to achieve intracardiac pacing is not possible. Although procedures to cross and recanalize previously occluded central veins is possible for
Pacing the conduction tissue of the heart directly is an exciting development within cardiology. CSP has the potential to supersede conventional right ventricular pacing. The benefits are in replicating the natural electrical conduction of the heart with a physiological narrow QRS morphology similar to intrinsic conduction. One major benefit of CSP has been its ability to reverse left bundle branch block, potentially replacing conventional CRT in the future once further data is available from upcoming trials. Thus far small trials have shown significant benefits in terms of reduction of heart failure, atrial fibrillation and mortality in those receiving >40% RV pacing. The exact physiological mechanism whereby pacing near the conduction system can reverse left bundle branch block is controversial and much debated

Those with dyspnoea/ fatigue were also more commonly women (42%) compared to patients with chest pain as the main symptom (29% women) or syncope (37% women). Compared to the other two groups, patients with dyspnoea/fatigue as their main symptom were more likely to have high blood pressure, diabetes, chronic kidney disease and chronic obstructive pulmonary disease (COPD).
Dr Medeiros explained, “Shortness of breath was more common among patients that died during
He concluded, “This study highlights the need to consider a diagnosis of myocardial infarction even when the primary complaint is not chest pain. This may be particularly important for women and older patients where diagnosis could be delayed and result in worse outcomes. In addition to the classic heart attack symptom of chest pain, pressure, or heaviness radiating to one or both arms, the neck or jaw, people should seek urgent medical help if they experience prolonged shortness of breath.”
Shortness of Breath Heralds Worse Survival than Chest Pain for Heart Attack Patients
“The first step must be to follow the UK’s plan to protect children in particular from relentless pestering by junk food companies by introducing an online marketing ban and a 9pm TV advertising
“Dyspnoea and extreme tiredness were more common heart attack symptoms in women, older people and patients with other conditions such as high blood pressure, diabetes, kidney disease and lung disease,” said study author Dr Paulo Medeiros of Braga Hospital, Portugal. “While our study did not show that these symptoms cause poorer outcome, they were warning signs of greater risk.”

The Government needs to tackle the “intense marketing” of junk food to kids to protect children from childhood obesity, the Irish Heart Foundation has said.
Obesity is one of the biggest public health challenges in Ireland today, affecting many thousands of people, yet those living with obesity lack support and face stigma at work, home and in the health system.
Obesity is a chronic, complicated disease as well as a driver of other
The study focused on non-STelevation myocardial infarction (NSTEMI), a type of heart attack in which an artery supplying blood to the heart becomes partially blocked. The researchers used data from the Portuguese Registry of Acute Coronary Syndromes. The study included 4,726 patients aged
Just 76% of heart attack patients with dyspnoea or fatigue as their main symptom are alive at one year compared to 94% of those with chest pain as the predominant feature. That’s the finding of research presented today at ESC Acute CardioVascular Care 2022, a scientific congress of the European Society of Cardiology (ESC).1

The researchers compared rates of survival between the three groups at one year. At one year after the heart attack, 76% of patients in the dyspnoea/fatigue group were alive compared with 94% of the chest pain group and 92% of the syncope group. During the year after their heart attack, 76% of patients in the dyspnoea/ fatigue group avoided being hospitalised for a cardiovascular
drivers include the high volume and availability of energy dense, nutrient poor food and beverages –including the emergence of a global snack food industry now worth $374 billion a year; the intense marketing of these products; their relative cheapness compared to healthy alternatives.
The average age of study participants was 68 years and 71% were men. Patients were divided into three groups according to their main symptom at presentation. Chest pain was the most common presenting symptom (4,313 patients; 91%), followed by dyspnoea/fatigue (332 patients; 7%) and syncope (81 patients; 2%).4
the year after their heart attack. However, when considering all of the studied variables, the type of presenting symptom was not an independent predictor of mortality, meaning that we cannot specifically state that shortness of breath was the reason for the worse outcome. Poorer survival may be due to other factors in those patients, such as reduced heart pump function.”
“The State’s own research estimates that 85,000 of this generation of children on the island of Ireland will die prematurely due to overweight and obesity. But this number is likely to be even higher after a pandemic which has seen children’s intake of unhealthy foods increase and their access to physical activity fall,” he added.
Chest pain is the hallmark presentation of myocardial infarction2 but other complaints such as shortness of breath, upper abdominal or neck pain, or transient loss of consciousness (blackouts) may be the reason to attend the emergency department.3 This study investigated which patients tend to present with atypical complaints and whether these symptoms result in the same consequences as chest pain.
reason compared with 85% of the chest pain group and 83% of the syncope group.
The researchers then conducted a multivariate analysis to assess whether chest pain, dyspnoea/fatigue or syncope were independent predictors of one-year survival. The analysis was adjusted for age, COPD, atrial fibrillation, left ventricular ejection fraction, major bleeding, and ventricular tachycardia. None of the symptoms emerged as independent predictors.
Dr Medeiros said, “Patients presenting with shortness of breath or fatigue had a worse prognosis than those with chest pain. They were less likely to be alive one year after their heart attack and also less likely to stay out of hospital for heart problems during that 12-month period.”
Speaking on World Obesity Day, Mr Chris Macey, Director of Advocacy at the Irish Heart Foundation, said that no significant progress on protecting children from childhood obesity can be made until the Government tackles the key drivers of the obesity epidemic.
diseases such as heart disease and stroke, with serious implications for individuals, families, societies and economies. The need to act has been made more urgent by the impact of the Covid19 pandemic on weight related behaviours in children, young people and adults.
ELIQUIS® (apixaban) (SmPC) tablets; 5 and 2.5 mg apixaban. (SPC section 4.1): stroke systemic embolism with non-valvular atrial fibrillation (NVAF) with or more risk factors, such as prior stroke or transient ischaemic attack (TIA), age ≥ 75 years, thrombosis (DVT) embolism (PE), haemodynamically (VTE) surgery (2.5 mg only). DOSAGE AND ADMINISTRATION (SPC section 4.2): Oral. Taken with water, with or without food. Prevention of stroke and systemic embolism in patients with NVAF: The recommended dose is 5 mg twice a day. In patients who meet at least two of the following criteria: serum creatinine ≥ 1.5 mg/dL (133 micromole/L), age ≥ 80 years, or body weight ≤ 60 kg the recommended dose is Eliquis, 2.5 mg twice daily. Patients with severe renal impairment (creatinine clearance 15-29 ml/min) should receive Eliquis 2.5 mg twice daily. Therapy should be continued long term. Treatment of DVT, treatment of PE and prevention of recurrent DVT and PE (VTEt): The recommended dose for the treatment of acute DVT and treatment of PE is 10 mg twice daily for the first 7 days followed by 5 mg twice daily. As per available medical guidelines, short duration of treatment (at least 3 months) should be based on transient risk factors (e.g. recent surgery, trauma, immobilisation). The recommended dose for the prevention of recurrent DVT and PE is 2.5 mg twice daily. When prevention of recurrent DVT and PE is indicated, the 2.5 mg twice daily dose should be initiated following completion of 6 months of treatment with Eliquis 5 mg twice daily or with another anticoagulant. The duration of overall therapy should be individualised after careful assessment of the treatment benefit against the risk for bleeding. Prevention of VTE (VTEp): elective hip or knee replacement surgery: The recommended dose is 2.5 mg twice a day. The initial dose should be taken 12 to 24 hours after surgery. Hip replacement surgery, the recommended duration of treatment is 32 to 38 days. Knee replacement surgery, the recommended duration of treatment is 10 to 14 days. Missed Dose for All Indications: If a dose is missed, Eliquis should be taken immediately and then continue with twice daily dose as before. Switching: Switching treatment from parenteral anticoagulants to Eliquis (and vice versa) can be done at the next scheduled dose. These medicinal products should not be administered simultaneously. Switching treatment from VKA therapy to Eliquis: Warfarin or other VKA therapy should be discontinued and Eliquis started when the international normalized ratio (INR) is < 2. Switching treatment from Eliquis to VKA therapy: Administration of Eliquis should be continued for at least 2 days after beginning VKA therapy. After 2 days of co- administration of Eliquis with VKA therapy, an INR should be obtained prior to next scheduled dose of Eliquis. Co-administration of Eliquis and VKA therapy should be continued until the INR is ≥2. Renal Impairment - mild or moderate renal impairment: For the prevention of VTE in elective hip or knee replacement surgery (VTEp), for the treatment of DVT, treatment of PE and prevention of recurrent DVT and PE (VTEt), no dose adjustment is necessary. For the prevention of stroke and systemic embolism in patients with NVAF and serum creatinine ≥ 1.5 mg/dL (133 micromole/L) associated with age ≥ 80 years or body weight ≤ 60 kg, a dose reduction is necessary. In the absence of other criteria for dose reduction (age, body weight), no dose adjustment is necessary. Severe renal impairment (creatinine clearance 15-29 mL/min): For the prevention of VTE in elective hip or knee replacement surgery (VTEp), for the treatment of DVT, treatment of PE and prevention of recurrent DVT and PE (VTEt), Eliquis is to be used with caution. For the prevention of stroke and systemic embolism in patients with NVAF, patients should receive the lower dose of Eliquis 2.5mg twice daily. In patients with creatinine clearance < 15 mL/min, or in patients undergoing dialysis, there is no clinical experience therefore Eliquis is not recommended. See SmPC for further details. Hepatic impairment: Contraindicated in patients with hepatic disease associated with coagulopathy and clinically relevant bleeding risk. Not recommended in patients with severe hepatic impairment. Use with caution in patients with mild or moderate hepatic impairment (Child Pugh A or B). No dose adjustment is required in patients with mild or moderate hepatic impairment. Use with caution in patients with elevated liver enzymes (ALT/AST >2 x ULN) or total bilirubin ≥ 1.5 x ULN. Prior to initiating Eliquis, liver function testing should be performed. Catheter ablation (NVAF): Patients can continue Eliquis use while undergoing catheter ablation. Cardioversion (NVAF): Eliquis can be initiated or continued in NVAF patients who may require cardioversion. See SmPC for further details. Patients with NVAF and acute coronary syndrome (ACS) and/or percutaneous coronary intervention (PCI): There is limited experience of treatment with apixaban at the recommended dose for NVAF patients when used in combination with antiplatelet agents in patients with ACS and/or undergoing PCI after haemostasis is achieved. See SmPC for further details. Paediatric population: Eliquis is not recommended in children and adolescents below the age of 18. CONTRAINDICATIONS (SPC section 4.3): Hypersensitivity to active substance or to excipients, active clinically significant bleeding, hepatic disease associated with coagulopathy and clinically relevant bleeding risk, lesion or condition if considered a significant risk factor for major bleeding, see SmPC for further details. Concomitant treatment with any other anticoagulant agent except under specific circumstances of switching anticoagulant therapy or when unfractionated heparin (UFH) is given at doses necessary to maintain an open central venous or arterial catheter or when UFH is given during catheter ablation for atrial fibrillation, see SmPC for further details. WARNINGS AND PRECAUTIONS (SPC section 4.4): Haemorrhage risk: Carefully observe for signs of bleeding. Use with caution in conditions with increased risk of haemorrhage. Discontinue administration if severe haemorrhage occurs. An agent to reverse the anti-factor Xa activity of apixaban is available. For information on reversal and managing bleeding, see SmPC for further details. Interaction with other medicinal products affecting haemostasis: Concomitant treatment with any other anticoagulant is contraindicated (see contraindications). Concomitant use of Eliquis with antiplatelet agents increases the risk of bleeding. Care with concomitant SSRIs, SNRIs or NSAIDs, including acetylsalicylic acid. Following surgery, other platelet aggregation inhibitors are not recommended concomitantly with Eliquis. In patients with atrial fibrillation and conditions that warrant mono or dual antiplatelet therapy, a careful assessment of the potential benefits against the potential risks should be made before combining this therapy with Eliquis. A clinical trial enrolled patients with atrial fibrillation with ACS and/or undergoing PCI and a planned treatment period with a P2Y12 inhibitor, with or without ASA, and oral anticoagulant (either apixaban or VKA) for 6 months. Concomitant use of ASA increased the risk of ISTH (International Society on Thrombosis and Hemostasis) major or CRNM (Clinically Relevant Non-Major) bleeding in apixaban-treated subjects. See SmPC for further details. Use of thrombolytic agents for the treatment of acute ischemic stroke: Limited experience. Patients with prosthetic heart valves: safety and efficacy of Eliquis have not been studied in patients with prosthetic heart valves, with or without atrial fibrillation. Therefore, the use of Eliquis is not recommended in this setting. Patients with antiphospholipid syndrome: Direct acting Oral Anticoagulants (DOACs), including Eliquis, are not recommended for patients with a history of thrombosis who are diagnosed with antiphospholipid syndrome (see SmPC for further details). Surgery and invasive procedures: Discontinue at least 48 hours prior to elective surgery or invasive procedures with a moderate or high risk of bleeding. Discontinue at least 24 hours prior to elective surgery or invasive procedures with a low risk of bleeding. If surgery or invasive procedures cannot be delayed, appropriate caution should be exercised, taking into consideration an increased risk of bleeding. Eliquis should be restarted after the invasive procedure or surgical intervention as soon as possible provided the clinical situation allows and adequate haemostasis has been established. For patients undergoing catheter ablation for atrial fibrillation, Eliquis treatment does not need to be interrupted. Temporary discontinuation: Discontinuing anticoagulants, including Eliquis, for active bleeding, elective surgery, or invasive procedures places patients at an increased risk of thrombosis. Lapses in therapy should be avoided and if anticoagulation with Eliquis must be temporarily discontinued for any reason, therapy should be restarted as soon as possible. Spinal/ epidural anaesthesia or puncture Patients treated with antithrombotic agents for prevention of thromboembolic complications are at risk of developing an epidural or spinal haematoma which can result in long- term or permanent paralysis. The risk of these events may be increased by the post- operative use of indwelling epidural catheters or the concomitant use of medicinal products affecting haemostasis. Indwelling epidural or intrathecal catheters must be removed at least 5 hours prior to the first dose of Eliquis. The risk may also be increased by traumatic or repeated epidural or spinal puncture. Patients are to be frequently monitored for signs and symptoms of neurological impairment (e.g., numbness or weakness of the legs, bowel or bladder dysfunction). If neurological compromise is noted, urgent diagnosis and treatment is necessary. Prior to neuraxial intervention the physician should consider the potential benefit versus the risk in anticoagulated patients or in patients to be anticoagulated for thromboprophylaxis. There is no clinical experience with the use of Eliquis with indwelling intrathecal or epidural catheters. See SmPC for further details. Haemodynamically unstable PE patients or patients who require thrombolysis or pulmonary embolectomy: Eliquis is not recommended as an alternative to unfractionated heparin in patients with pulmonary embolism who are haemodynamically unstable or may receive thrombolysis or pulmonary embolectomy since the safety and efficacy of Eliquis have not been established. Patients with active cancer: Patients with active cancer can be at high risk of both venous thromboembolism and bleeding events. When apixaban is considered for DVT or PE treatment in cancer patients, a careful assessment of the benefits against the risks should be made. Renal impairment: see dosage and administration section. Elderly patients: Increasing age may increase haemorrhagic risk. Also, the co-administration of Eliquis with ASA in elderly patients should be used cautiously because of a potentially higher bleeding risk. Body weight: Low body weight (< 60 kg) may increase haemorrhagic risk. Hepatic impairment: see dosage and administration section. Interaction with Inhibitors of CYP3A4 and P-gp: Not recommended with strong inhibitors of both CYP3A4 and P-gp. These medicinal products may increase Eliquis exposure by 2-fold or greater in the presence of additional factors that increase Eliquis exposure (e.g. severe renal impairment) see SmPC for further details. Interaction with Inducers of CYP3A4 and P-gp: Eliquis should not be used for the treatment of DVT and PE in patients receiving concomitant systemic treatment with strong inducers of both CYP3A4 and P-gp since efficacy may be compromised. Concomitant systemic treatment with strong inducers of both CYP3A4 and P-gp, Eliquis should be used with caution for the prevention of VTE in elective hip or knee replacement surgery, for the prevention of stroke and systemic embolism in patients with NVAF and for the prevention of recurrent DVT and PE, though no dose adjustment for Eliquis is required during concomitant therapy with such medicinal products. Hip fracture surgery: Eliquis has not been studied in clinical trials in patients undergoing hip fracture surgery. Therefore, it is not recommended in these patients. Laboratory parameters Clotting tests (PT, INR, and aPTT) are affected by the mechanism of action of apixaban. Changes observed at the expected therapeutic dose are small and subject to a high degree of variability, see SmPC for further details. Information about excipients: Eliquis contains lactose. Patients with galactose intolerance, total lactase deficiency or glucose-galactose malabsorption should not take Eliquis. DRUG INTERACTIONS (SPC Section 4.5): Eliquis should be used with caution when co-administered with SSRIs/SNRIs, NSAIDs, ASA and/or P2Y12 inhibitors because these medicinal products typically increase the bleeding risk. There is limited experience of co-administration with other platelet aggregation inhibitors (such as GPIIb/IIIa receptor antagonists, dipyridamole, dextran or sulfinpyrazone) or thrombolytic agents. As such agents increase the bleeding risk, co-administration of these products with Eliquis is not recommended. See SmPC for further details.Due to an increased bleeding risk, concomitant

treatment with any other anticoagulants is contraindicated, except under specific circumstances of switching anticoagulant therapy, when UFH is given at doses necessary to maintain an open central venous or arterial catheter or when UFH is given during catheter ablation for atrial fibrillation. Administration of activated charcoal reduces Eliquis exposure. Also see contraindications and special warnings and precautions section; Consult SmPC (contraindications, special warnings and precautions and drug interactions) for full details on interactions. PREGNANCY AND LACTATION (SPC section 4.6): Pregnancy: As a precautionary measure, it is preferable to avoid the use of apixaban during pregnancy. Breastfeeding A decision must be made whether to discontinue breast-feeding or to discontinue/abstain from apixaban therapy taking into account the benefit of breast-feeding for the child and the benefit of therapy for the woman. UNDESIRABLE EFFECTS (SPC section 4.8): Increased risk of occult or overt bleeding from any tissue or organ, which may result in post haemorrhagic anaemia. The signs, symptoms, and severity will vary according to the location and degree or extent of the bleeding. Frequencies: common (≥ 1/100 to < 1/10); uncommon (≥ 1/1,000 to < 1/100); rare (≥ 1/10,000 to < 1/1,000); very rare (< 1/10,000); not known (cannot be estimated from the available data). Prevention of VTE in adult patients who have undergone elective hip or knee replacement surgery (VTEp): Common: anaemia; haemorrhage*; haematoma*; nausea; contusion. Uncommon: thrombocytopenia*; epistaxis*; haematochezia*; liver function test abnormal (including blood bilirubin increased*); haematuria*; specific haemorrhage such as gastrointestinal*, abnormal vaginal*, urogenital*, post procedural*, wound secretion*, incision site*, operative*.

Introduction

2. In apparently healthy persons, the risk of a heart attack or stroke relates strongly to the combined effects of smoking, cholesterol level and blood pressure, often combined with overweight, inactivity and consequent diabetes.
Because CVD generally arises from a combination of risk factors, and clinical estimation of these effects is poor, all CVD prevention guidelines recommend some sort of risk estimation system such as the European SCORE4 or the American Pooled Cohort Equation. However, these systems are relatively crude, attempt to apply population data to individuals, and generally start at age 40- after 40 years of possible exposure to risk factors.
1. In 2020 the Board of the European Society of Cardiology (ESC) established a multidisciplinary Cardiovascular Risk Collaboration (CRC) in the European Heart health Institute in Brussels.
The Cardiovascular Risk Collaboration (CRC) was stablished by the Board of the ESC in 2020 to contribute to the ESC's mission to reduce the burden on cardiovascular disease by researching new aspects of risk estimation and developing their practical application.
This paper outlines the rationale for the ESC's Cardiovascular Risk Collaboration and its various work packages. We then present its first two completed deliverables, the SCORE22 and SCORE2 OP3 (older persons) risk charts , and finish with some thoughts for the future.
4. The previously used European Society of Cardiology's (ESC) risk estimation system, SCORE, estimated 10 year risk of fatal CVD and there was a strong demand to estimate risk of total (fatal and non-fatal) CVD events.
It was therefore decided to develop a multidisciplinary partnership to explore these issues under a steering Committee:
Because CVD generally arises from a combinat1on of risk factors, and clinical estimation of these effects is poor, all CVD prevention guidelines recommend some sort of risk estimation system such as the European SCORE4 or the American Pooled Cohort Equation. However, these systems are relatively crude, attempt to apply population data to individuals, and generally start at age 40 after 40 years of possible exposure to risk factors.
7. The CRC believes that the future of risk estimation may lie in applying artificial intelligence to both genetic and environmental factors to allow more personalised risk estimation from early life on, using an exposure time model rather than age per se.
3. Clinical estimation of these effects is imperfect, therefore all guidelines on cardiovascular disease (CVD) prevention recommend some form of risk chart or calculator.
The ESC's original SCORE2 system was a powerful brand but based on old data with a limited number of variables. It was criticised because it estimated only the risk of CVD mortality, and there was a strong demand for total event (fatal +nonfatal CVD) charts. This proved more challenging than one might have expected, due to the heterogeneity and very variable quality of nonfatal event data throughout Europe. It was based on 680,000 individuals from 45 cohorts in 13 countries. A multiplicative approach was used to convert mortality to total events. The process may be summarised from the graphical abstract from the main SCORE2 paper4:

5. The CRC responded to this by developing total event charts for both middle aged (SCORE2) and older persons (SCORE2-OP). These have been included in the 2021 ESC Guidelines on CVD Prevention in Clinical Practice1
The chart appropriate to Ireland is as follows. It will be noted that gender differences are modest, perhaps because the highest risk men have already died.
In conclusion, we have presented an outline of the rationale and work plan of the ESC Cardiovascular Risk Collaboration. The new SCORE2 and SCORE2-OP risk estimation systems have been presented and we summarise what may be a radical new approach to risk estimation.
Based on the work and thoughts of Brian Ference, the CRC is attempting to address some of these issues. This approach regards risk as exposure time, such as units of cholesterol, BP or total risk over time. This reduces the problem of the domination of present systems by age. Future risk is determined by the rate of rise of these variables.

Further, the gradient (expected rate of rise of risk) may help to determine subjects who could benefit from earlier lifestyle advice and perhaps easrly imaging such as CT calcium scoring, and others in whom this would be expected to have a very low yield. Some of these issues are addressed in an editorial that accompanied the SCORE2 papers.6

All current risk estimation systems share substantial limitations-
Based on the work and thoughts of Brian Ference, the CRC is attempting to address some of these issues. This approach regards risk as exposure time, such as units of cholesterol, BP or total risk over time. This reduces the problem of the domination of present systems by age. Future risk is determined by the rate of rise of these variables. Mendelian randomisation studies suggest that the rise in cholesterol and blood pressure from early life on is substantially determined by polymorhisms that may have a small impact on five year risk but a very large impact on lifetime, 50 70 year risk. To this must be added the progressively more important impact of lifestyle and environmental factors. It is planned to apply artificial intelligence techniques to these issues in an attempt to achieve more precise and personalised risk estimates applicable at a much earlier stage, perhaps in the 20s. Further, the gradient (expected rate of rise of risk) may help to determine subjects who could benefit from earlier lifestyle advice and perhaps easrly imaging such as CT calcium scoring,

Aetiology of AF
Atrial fibrillation is often asymptomatic, especially in the elderly, but many patients experience palpitations, rapid and irregular heartbeat, vague chest discomfort or symptoms of heart failure such as weakness, light-headedness and dyspnoea, particularly when the ventricular rate is very rapid (140 to 160 beats/
Theresa, who is a Clinical Nurse Specialist and Associate Lecturer Institute of Technology Carlow adds, “Due to increased lifespan, atrial fibrillation is on the rise and predicted to affect 14-17 million people in Europe by 2030, with 120,000-215,000 new cases per year (estimated incidence 0.23–0.41 per 1,000 person/years).
minute). Patients may also present with signs and symptoms of acute CVA or other organ damage due to systemic emboli.
AF is associated with a significant risk of transient ischemic attack, ischemic stroke, systemic embolism, and death. While not immediately life-threatening, it does carry a five-fold higher risk of stroke caused by the formation of blood clots in the heart and blocked blood vessels in the brain.

“In particular, 7–8.5 million people will be affected by permanent AF, 3.5–4.2 by persistent AF, and 3.5–
In Ireland, 11% of people over the age of 80 have atrial fibrillation and it affects more than 40,000 people in Ireland aged over 50 years.
Atrial fibrillation is multi factorial in nature. Abnormalities or damage to the heart's structure are the most common causes.
AF constitutes a public health challenge with high comorbidity and increased mortality risk and is a significant cause of increasing health care costs globally. An estimated 1.4% of all adults over 65 years living with undiagnosed AF means more cases of unmanaged atrial fibrillation will create even further economic strain on our healthcare systems. FIBRILLATION
“ECG findings for AF indicate the absence of P waves, irregularly irregular R-R intervals and the presence of f (fibrillatory) waves between the QRS complexes. Fibrillatory waves are irregular in timing and morphology with baseline undulations at rates up to or > 300/ minute, best seen in lead V1 and not always apparent in all leads.

pericarditis, heart valve and congenital heart disease. A family history of AF may also increase the risk. AF is also associated with other medical conditions, such as, pneumonia, lung cancer, pulmonary embolism, sarcoidosis, obstructive sleep apnoea, hyperthyroidism and obesity. A number of triggers are associated with the condition including smoking, excessive alcohol and or coffee consumption. When no other medical conditions are associated with it, it is called lone atrial fibrillation.”
“While it can sometimes affect people who are physically very fit, AF is more common in people with other heart conditions such as hypertension, atherosclerosis, cardiomyopathy, pericarditis, heart valve and congenital heart disease. A family history of AF may also increase the risk. AF is also associated with other medical conditions, such as, pneumonia, lung cancer, pulmonary embolism, sarcoidosis, obstructive sleep apnoea, hyperthyroidism and obesity. A number of triggers are associated with the condition including smoking, excessive alcohol and or coffee consumption. When no other medical conditions are associated with it, it is called lone atrial fibrillation.”
Theresa explains, “Diagnostic investigation of AF typically includes a complete medical history and physical examination, ECG, full blood count, Urea and Electrolytes and serum thyroid stimulating hormone level. All patients who present with symptoms of AF should have at minimum their pulse checked for irregularities as well as a 12-lead ECG.
Current Developments in Atrial Fibrillation
“Atrial fibrillation is more common with increased age and affects certain groups of people more than others,” adds Theresa.
Atrial fibrillation is often asymptomatic, especially in the elderly, but many patients experience palpitations, rapid and irregular heartbeat, vague chest discomfort or symptoms of heart failure such as weakness, light headedness and dyspnoea, particularly when the ventricular rate is very rapid (140 to 160 beats/minute). Patients may also present with signs and symptoms of acute CVA or other organ damage due to systemic emboli.
Diagnosis and Screening
Characterised by the rapid and irregular beating of the atrial chambers of the heart, episodes of which may become longer or continuous over time, Atrial fibrillation (AF) is the most common cardiac arrhythmia diagnosed in clinical practice. The condition affects more than 33 million people around the world.
Theresa explains, “Diagnostic investigation of AF typically includes a complete medical history and physical examination, ECG, full blood count, Urea and Electrolytes and serum thyroid stimulating hormone level. All patients who present with symptoms of AF should have at minimum their pulse checked for irregularities as well as a 12 lead ECG.
“ECG findings for AF indicate the absence of P waves, irregularly irregular R R intervals and the p resence of f (fibrillatory) waves between the QRS complexes. Fibrillatory waves are irregular in timing and morphology with baseline undulations at rates up to or > 300/minute, best seen in lead V1 and not always apparent in all leads.
Diagnosis and Screening
“NOACs have major pharmacologic advantages over warfarin, which is a vitamin K antagonist, including rapid onset/offset of action, few drug interactions and predictable pharmacokinetics. Practical advantages of novel oral anticoagulants over warfarin include fixed once or twice-daily oral dosing without the need for coagulation monitoring. Potential drawbacks include a risk of bleeding that might be increased in patients over 75 years of age, the lack of a routine laboratory test to reliably measure anticoagulant effect and previously, the lack of an antidote for reversal.
The European Society of Cardiology (ESC) distinguishes five types of AF based on presentation and duration of arrhythmia seen in the table at the foot of the page.

Atrial fibrillation is a progressive disorder. The exact electropathological mechanisms underlying persistence of AF are at present unknown and none of the available recording techniques can determine the degree and extensiveness of atrial electropathology or determine the stage of the condition at any time in the process.

“Choice of NOAC is influenced by the patients individual characteristics, including risk of stroke or VTE, risk of bleeding and comorbidity, in particular renal dysfunction. It is also recommended that one of the bleeding risk scores, such as the HAS-BLED score, be used to help risk-assess patients. The choice of agent should take into consideration the patient’s age,

Many medications that are effective in countering arrhythmias can also provoke them in some instances. Patients must be monitored closely as common side effects of anti-arrhythmic medications include, hypotension, fatigue, nausea, vomiting, possible issues with liver, kidneys, thyroid or lungs and heart rhythm disorders.

“First line drugs include beta blockers such as propranolol or atenolol and nonhydropyridine calcium channel blockers such as diltiazem or verapamil, which slows the conduction of impulses to the ventricles. Digoxin may be added to control the heart rate further. Digoxin is usually only effective for controlling the ventricular rate at rest and should therefore only be used as a monotherapy in predominantly sedentary patients.

Permanent AF Permanent AF is said to exist when the presence of the arrhythmia is accepted by the patient and physician. Rhythm control interventions, by definition, are not pursued in patients with permanent AF
The first step, she notes, is to try to find the cause of the atrial fibrillation. “For example, hyperthyroidism can sometimes be the underlying cause of AF and medication to control the condition can correct the symptoms of atrial fibrillation. If no underlying cause is found, treatment of AF is usually aimed at either rhythm or rate control. Since AF induces electrical, structural, and contractile remodelling, therapy aimed at prevention or restoration of remodelling and consequently restoration of sinus rhythm should be the first choice strategy. The different AF treatment modalities include pharmacological therapy, electrical cardioversion, pacemaker implantation combined with His bundle ablation or surgical isolation of the pulmonary veins with or without additional linear lesions/ substrate modification.

Systemic emboli can also cause malfunction or necrosis of other organs. Atrial fibrillation may impair cardiac output. Loss of atrial contraction can lower cardiac output at normal heart rate by about 10%. Such a decrease is usually well tolerated except when the ventricular rate becomes too fast (> 140 beats/ minute), or when patients already have borderline or low cardiac output. In such cases, cardiac failure may develop.”

Complications
“Other diagnostic tests for AF include CXR and echocardiogram. Echocardiography is carried out to assess for structural heart defects such as left atrial enlargement, left ventricular wall motion abnormalities suggesting past or present ischemia, valvular disorders and cardiomyopathy and to identify additional risk factors for stroke such as atrial blood stasis, t hrombus or complex aortic plaque. Atrial thrombi are more likely in the atrial appendages, where they are best detected by transo esophageal rather than transthoracic Atrialechocardiography.”fibrillationis
The European Society of Cardiology (ESC) distinguishes five types of AF based on presentation and duration of arrhythmia.
The choice of anti-arrhythmic depends on the type of AF, comorbidities, side effects of the medicine chosen and response to therapy. Some patients may need more than one anti-arrhythmic to control atrial fibrillation and a variety of medications are available
Complications
The absence of atrial contractions in atrial fibrillation predisposes the patient to thrombus formation.
Treatment
Treatment of atrial fibrillation varies from person to person and depends on the type of AF, symptoms, treatment of any underlying cause, age, and overall health.
Classification of Atrial Fibrillation
recommended to prevent strokes caused by atrial fibrillation. Theresa explains, “Patients with a high or moderate level of risk of stroke or thrombus formation due to atrial fibrillation, are usually prescribed an anticoagulant such as warfarin or a newer type of anticoagulant-novel oral anticoagulants (NOACs) also called direct oral anticoagulants (DOACs), such as dabigatran, rivaroxaban, apixaben or edoxaben. There are fewer dietary and medication interactions with the newer agents, and less need for monitoring. NOACs are at least as effective or superior to warfarin for stroke prevention in patients with non-valvular atrial fibrillation, and are at least as safe or safer in terms of bleeding risk, according to three large clinical trials.
“Anti-arrhythmic medication can control atrial fibrillation by restoring normal heart rhythm and controlling the rate at which the heart beats.
Pharmacologic cardioversion, also referred to as chemical cardioversion, uses anti-arrhythmic medication instead of an electrical shock. Pharmacological cardioversion is often used for the treatment of atrial fibrillation of recent onset. Flecainide, ibutilide, propafenone and vernakalant can be used in patients with no structural heart disease. Where structural heart disease is present, intravenous amiodarone is the drug of choice. Flecainide administered intravenously in patients with AF of recent onset has been shown to restore sinus rhythm in 72-95 % of patients, with greatest success rates in those who receive treatment within 24 hours of atrial fibrillation onset. When AF has persisted for >48 hours, pharmacological cardioversion is much less likely to be effective. Amiodarone appears to be the most effective agent for restoring sinus rhythm in patients with persistent atrial fibrillation.
Almost 11% of Irish adults aged 65 years and over attending general practice have atrial fibrillation. The HSE (2015) study ‘Atrial Fibrillation Screening in General Practice’ concluded that “opportunistic screening for an irregular pulse in General Practice to assist in the detection of AF is both feasible and beneficial”.

The choice among the therapies is based on the same considerations as for atrial fibrillation. Patients often require cardioversion or atrial flutter substrate ablation.”
weight and creatinine clearance, as dose adjustment may be required.”
“Both conditions carry increased risk of stroke. In atrial fibrillation, the atria beat irregularly. In atrial flutter, the atria beat regularly, but faster than usual and more often than the ventricles, and there may be four atrial beats to every one ventricular beat. During atrial flutter, unlike atrial fibrillation, electrical activity in the atria is coordinated. The atria do contract, but at a very rapid rate of 250 to 350 times per minute. This rate is too fast to allow every impulse to be conducted through the atrioventricular node to the ventricles. Because the AV node cannot usually conduct at this rate, typically half of the impulses get through (2:1 block), resulting in a regular ventricular rate of 150 beats/minute. The diagnosis of atrial flutter is by electrocardiography. In typical flutter, ECG shows continuous and regular atrial activation with a saw tooth pattern, most obvious in leads II, III, and aVF.
In 2015, HIQA published a ‘Health technology assessment (HTA) of a national screening programme for atrial fibrillation in primary care’ The HTA announced that a national screening programme for atrial fibrillation for over 65s in primary care would be cost-effective.
Theresa concludes, “General practices are well placed to opportunistically screen older patients and are ideal in terms of the pathway for treatment for those identified. Opportunistic screening for an irregular pulse carried out by GPs and GPNs “has the potential to be an extremely important stroke prevention strategy, capable of saving society and the health service significant social and economic costs”.

For patients who have been in AF for longer than 12 24 hours, or in whom the duration of the arrhythmia is not clear, a minimum period of anticoagulation of three weeks is recommended before cardioversion. “Even if echocardiography has demonstrated no thrombus before cardioversion, patients should be anticoagulated for at least one month post cardioversion, since mechanical atrial function may return slowly after cardioversion,” Theresa adds.

Screening for Atrial Fibrillation in General Practice
HIQA’s Director of Health Technology Assessment Dr Máirín Ryan, said; “Based on the best available evidence, annual opportunistic pulse palpation for those aged 65 and older is expected to lead to reductions in the incidence and severity of atrial fibrillation-related strokes assuming that those detected by screening have a comparable risk of stroke as those detected through routine care.”
For patients who have been in AF for longer than 12-24 hours, or in whom the duration of the arrhythmia is not clear, a minimum period of anticoagulation of three weeks is recommended before cardioversion. “Even if echocardiography has demonstrated no thrombus before cardioversion, patients should be anticoagulated for at least one month post cardioversion, since mechanical atrial function may return slowly after cardioversion,” Theresa adds.

The development of radiofrequency (RF) ablation as a method of creating a permanent thermal myocardial injury occurred some years later in the late 1980s. It has standardised the treatment of a multitude of cardiac arrhythmias without the reliance on subsequent pacemaker implantation from AV node ablation. Cryoablation techniques – ‘freezing’ as a form of permanent thermal myocardial injury - were also developed around this time. Despite advantages of reduced collateral damage, RF ablation currently remains the most commonly used strategy for treating most arrhythmias.

developed in 1995, has optimised the integration of an intracardiac anatomy with the electrophysiological features of an arrhythmia. The ability to create a real time cardiac chamber geometry comes from magnetic location technology (Carto, Biosense Webster). It identifies the location of sensors within special catheters and calculates the location of the catheter according to current frequencies thereby creating a reconstruction of a heart as the catheter is moved around a chamber. The subsequent geometry can then display the volume of scar within a chamber (by measuring the peak-to-peak amplitude of signals in contact with myocardium from the sensorbased catheter), and/or the timing of arrhythmias to identify its origin or perpetuating circuit.

Catheters were first used for intra-cardiac recording in the mid1960s, with dedicated protocols for ‘programmed’ stimulation or testing, developed in the mid1970s. The first microprocessorbased stimulator was developed in 1980, with the ability to deliver a pulse of current through a catheter in the heart to study a patient’s conduction system. A year later, the first ablation procedures were performed, using direct current (DC) shocks through an external defibrillator to ablate a patient’s AV node. All of these involved the sole use of X-ray to place catheters

Atrial tachycardias are commonly focal in origin but occur from one or more sites within atrial tissue. This includes both atria and their connections to other structures such as pulmonary veins within the left atrium and great vessels such as the aorta.
AV nodal reentry tachycardia (AVNRT) is the most common type of SVT. It results from a circuit circulating within the AV node that includes conduction occurring across two pathways in opposite directions within the AV node. Typically this includes two physiologically distinct channels within the AV node known as the fast and slow pathways.

Whilst there is a fast-learning curve associated with this therapy, it cannot be used to treat any other arrhythmias that often occur alongside AF, such as atrial tachycardia or atrial flutter. Similarly, the restrictive sizing of available balloons may result in suboptimal ablation in patients whose pulmonary veins are angulated or abnormally sized.
Laser balloon therapy is another available form of ablative therapy, but is used infrequently within EP centres, possibly due to the more established Cryo and RF therapy techniques currently in existence. Like other Cryoballoon technologies, it is typically used only in patients with paroxysmal AF. It too has a relatively short learning curve and recent developments in the balloon have improved procedural and fluoroscopy times. Additional use of the integration of imaging techniques such as intra-cardiac echocardiography can be especially important when performing Cryoballoon or laser balloon ablation where

3D reconstruction of a patient’s anatomy doesn’t occur during the Dueprocedure.tothepopularity and speed of balloon therapy techniques for AF, RF balloon therapy technology, with associated integration into 3D mapping systems, is currently on early market release in some European centres. It is hoped that it will provide the learning curve of balloon therapy but with advantages of having the concurrent ability to recreate 3D geometry rapidly and the capacity to safely re-ablate specific target areas within the pulmonary veins in cases of difficult or abnormal vein anatomy.
Developments in AF ablation
AF ablation techniques vary between paroxysmal and persistent AF patients, but all aim to treat the ‘triggers’ of AF. These triggers are mainly from the pulmonary veins from the left atrium. Electrical isolation of these veins (PVI) is the cornerstone of AF ablation for all patients as first line therapy.
historically been considered more time consuming than balloon counterparts. As such, some Electrophysiologists are known to use Cryoballoon treatments for AF.
As such, the use of ‘advanced’ 3D mapping systems has meant that mapping of these arrhythmias has increased in popularity due to improved safety and efficacy. Of late, technological advancements in these systems has resulted in the reduction, or obliteration, of the need for X-ray to perform diagnostic EP and ablation procedures. The ability to recreate a patient’s cardiac anatomy in 3D using these mapping systems, without X-ray, has become the focus of many EP labs - pertinent in the current era of a dramatic rise in the knowledge of the effect of radiation on electrophysiologists, staff, and patients alike, with long-term health effects. Even in patients with complex congenital anomalies, the use of 3D mapping for ablation of these SVT arrhythmias is further enhanced by the ability to integrate preprocedural imaging modalities such as CT, MRI, or intra-cardiac echocardiography with the chamber geometry for improved understanding of the mechanism of arrhythmias.
technological advancements have focused on improving RF lesion durability. The last decade has seen an introduction of contact force-sensing catheters. These ablation catheters provide an indication of the amount of contact that the ablation catheter has with the myocardium. This improved knowledge of tissue contact results in fewer RF ablations and improved lesion formation thereby improving both acute, and chronic success for AF ablation patients.
High Power Short Duration ablation technique for pulmonary vein isolation (90Watt 4seconds)
Radiofrequency ablation has been demonstrated as the most costeffective method of treating AF, for both paroxysmal and persistent AF patients. Several approaches have been developed for RF ablation of AF, but the end point for persistent AF ablation patients is still under debate, with long-term success rates for persistent patients being around 70% after one ablation procedure. Recent advances and developments around ablation strategies has vastly improved the success rates of maintaining a normal rhythm in many AF patients although inter-operator variation in ablation strategy varies widely.
As redo procedures have, until recently, demonstrated a disappointing level of chronic pulmonary vein isolation,
Current RF therapy techniques require technical have historically been considered more time consuming some Electrophysiologists are known to use Cryoballoon Cryotherapy is often utilised when only pulmonary normally those with a ‘normal’ heart and paroxysmal associated with this therapy, it cannot be used to treat alongside AF, such as atrial tachycardia or atrial available balloons may result in suboptimal ablation angulated or abnormally sized.
Patients with persistent AF are thought to have other substrates outside of the pulmonary veins, explaining the reduced success rates for these patients if ablation is limited to PVI only. As such, additional triggers within the left and right atrium are sought
Of late, there has been vast interest in high power, short duration ablation. Historically, pulmonary vein isolation for AF was performed with relatively low powers (3040 Watts) and moderate time durations for each RF lesion, giving lesions that were more affected by conductive heating effects rather than resistive heating. The latest technology and research suggests that high power (90 Watts), short duration RF applications cause a larger zone of resistive heating. This provides shallower but broader lesions, which may increase the lesion durability, lower procedural times, reduce the opportunity for collateral damage to structures such as the oesophagus, and minimise the dwell time of catheters within the arterial system. Where ablation for persistent AF patients requires additional ablation lesions in areas of thicker myocardial tissue, or for other concurrent arrhythmias, the same RF ablation catheters can still be utilised to complete all targets of ablations. Precise temperature feedback from the tip of the ablation catheter has been suggested to improve the safety profile of ablation and has the ability to automatically adjust saline irrigation rates and power to ensure that the tip does not overheat or have any char formation.

The demand for treatment of AF is increasing rapidly due to an ageing population and is known to increase the risk of all-cause mortality, heart failure, and thromboembolism. Whilst treatment with anticoagulants and rate control medication is well recognised, there is still a large gap in access to ablation for patients, with only 1-2% of patients with AF estimated to undergo ablation, despite the inclusion in numerous guidelines.
Current RF therapy techniques require technical expertise on the part of the physician and have
An alternative form of irreversible myocardial injury, by a technique called electroporation, is receiving a large amount of interest worldwide as the first non-thermal ablation technique for treatment of cardiac arrhythmias. PFA therapy causes cell death via a series of rapid, high voltage electrical pulses which damages targeted cell membranes of tissue in close proximity to the catheter. Having been used for the treatment of tumours in oncology, many companies are currently investigating the optimal waveform ‘recipe’ for safety and long-term success for use within AF ablation. Due to its tissue specificity, it is proposed that it will provide a form of ablation therapy that will limit damage to other noncardiac structures that are at risk from RF or Cryo therapies as well as enabling extremely rapid AF ablation procedural times.
A new ultra-low cryoablation system has just been released which has the capacity to be circular, linear, or curved in shape. It is hoped therefore that this can be used outside of isolation of the pulmonary veins for successful treatment of more AF patients than current Cryoballoon technology. Ultra-low cryoablation cools the tissue to -190°C compared to -70-80°C with traditional cryotherapy and thus should create more transmural lesions. Research into this new technology is ongoing.

In patients where a surgical option is not feasible, ongoing technological advancements with RF ablation strategies for persistent AF are ongoing. An example of this is Vein of Marshall ethanol infusion as an advocate for endocardial RF ablation of this bundle, thought to initiate or perpetuate AF in persistent patients. The highly challenging and limited success for RF endocardial ablation of the mitral isthmus has limited AF ablation techniques in this region to date and ethanol ablation thus far has identified limited complications but great success rates of both acute and chronic success for persistent AF patients.

For patients with stable VT, mapping in the arrhythmia does provide the best success rates for ablation procedures. For those with hemodynamically unstable VT, such as patients with ischemia, 3D mapping is often performed in sinus rhythm, with labelling and targeting of abnormal electrograms. However, in patients with high scar volumes, it may be unachievable to target all areas of late conduction when it is unknown which zone of late activation causes or maintains the VT circuit(s). Targeting all areas results in an unnecessarily high volume of ablation and doesn’t necessarily improve success rates.
Developments in VT ablation
Recent technological advancements in 3D mapping systems allow simultaneous mapping of the volume of scar alongside the ability to localise multiple VTs at the same time, with safety. This is important for patients with multiple ectopics, multiple VTs or substrates, and for whom extremely long procedural times are not well tolerated.

for these patients. RF ablation is typically the first form of ablation therapy offered for these patients. In patients where at least one RF ablation has failed to maintain sinus rhythm, a hybrid approach has been developed in the last few years. Here, minimally invasive surgery via a pericardioscopic approach from the upper abdomen, enables a cardiac surgeon to use RF energy epicardially to create block ablation lesions in both atria. This is pertinent in areas such as the posterior wall, which is renowned for having epicardial connections, where surgical ablation can assist in overall lesion integrity with concomitant, or subsequent endocardial ablation to validate the surgical ablation lines and, if necessary, add additional lines.

Use of the scar map to demonstrate areas of diseased tissue, alongside newly described techniques such as ‘DeEP’ and/ or ‘ILAM’ mapping, can help identify more specific ‘delayed conduction’ regions of diseased myocardium that are likely to be critical to the VT circuit. These strategies use various pacing protocols to improve specificity of target ablation areas within a ventricle within areas or channels of noticeable conduction delay. To date this has vastly improved the strategy and success rates for ischemic VTs where the volume of scar is often substantial.

The prevalence, awareness, treatment and control of hypertension in older adults with an Intellectual Disability in Ireland: a cross sectional study
Much of the research surrounding hypertension prevalence, awareness, treatment and control has focused on the general population. The prevalence of hypertension in those aged ≥18 years is 30–45%, and this increases steeply with the progression of age.3,6 In Ireland, cross sectional data from the Irish Longitudinal Study on Ageing (TILDA), which involves a nationally representative sample of older community adults aged >50 years, reported a weighted hypertension prevalence of 63.7%.7 Of those classified as hypertensive, 54.4% were aware they had hypertension, 58.9% were on antihypertensive treatment, with blood pressure controlled in just over half (51.6%).7 Murphy and colleagues7 concluded their study by drawing attention to the high prevalence of hypertension identified in Irish people over 50 and the low levels of awareness, treatment and control. They recommend population and primary care level interventions to reduce prevalence and improve awareness, detection and Theremanagement.hasnotbeen the same attention given in Ireland, to the prevalence of CVD, the role of hypertension and its treatment or indeed its under-treatment

An age of >40 years was selected because of the lower life expectancy for some individuals with ID and earlier onset of age-related morbidities in this population e.g. dementia.34,35 In total, 753 persons participated in Wave 1, meaning an overall response rate of 46% and 8.9% of the total population of persons >40 years registered on the 2008 NIDD database. A comparison with the published demographics of the 2008 NIDD cohort confirmed that the IDSTILDA sample was representative of the larger NIDD sample.36 For Wave 2 of IDS-TILDA, all living Wave 1 respondents (n=719) were invited to participate, from which 708 (98%) agreed to participate.

Past prevalence and risk studies on CVD and hypertension in persons with ID are largely limited by small, under-representative samples, lack of objective measures, and inconsistency in definitions. This has led to conflicting reports of lower,21 comparable10, 22-24 or higher levels of risk for persons with ID,25 when compared to the general population. In New York, Janicki et al.11 reported under-recognition of CVD in adults with ID compared to the general population, despite both groups having similar CVD mortality. Also in the US, Erickson and Kornexl26 identified a trend for lower proportions of people with ID as having a diagnosis of hypertension despite no significant differences between their diastolic blood pressure (DBP) recordings and those of the general population. Similarly, a national Swedish study21 reported that older adults with ID were less likely than the general population to have a diagnosis of hypertension and to be prescribed medication for it. Further, for those prescribed treatment, medications tended to be of the older variety compared to that prescribed for the general population.

Treatment: In the pre-interview questionnaire, participants/proxies were asked “Can you tell me what medications (including prescribed and over the counter, herbal medicines) you take on a regular basis – like every day or every week?” Interviewers subsequently confirmed this information with medication prescription data obtained from accompanying health care personnel. Medications were coded by two pharmacists using the World Health Organization (WHO) Anatomical Therapeutic Chemical (ATC) classification system,38 a method described in detail elsewhere.39 Antihypertensive treatment was defined as exposure to one or more of: anti-adrenergic agents, diuretics, beta-blockers, calcium channel blockers, ACE inhibitors and ARBs. Combination therapy included taking two or more antihypertensives concurrently. Medicines were recorded by brand or generic name, including

Prevalence was significantly higher in the oldest versus the youngest age group (p =0.000), in those with diabetes (p <0.001) and in those with a history of CVD (p=0.003). Conversely, having Down syndrome was associated with lower prevalence of hypertension (p<0.001) (Table 2).

Those with diabetes were 5.2 times more likely to be treated for hypertension compared to those who did not have a doctor’s diagnosis of diabetes (cOR=5.167, 95% CI 1.729-15.44). Those aged over 65 years were 5 times more likely to be treated for hypertension than those aged 44-49 (cOR=5.046, 95% CI 1.844-13.809).

Lower rates of hypertension, higher detection and greater efficacy of medication were found in those with ID, as was a lessor impact of risk factors such as obesity and low levels of physical activity. Among the diagnosed groups in both studies, participants with ID were more likely to be receiving antihypertensive treatment and when receiving treatment, participants with ID were more likely to have their blood pressure controlled and were taking less combination therapy, compared to TILDA participants.7 Of interest, when hypertension was

Conclusion
• Research is required to establish a CVD risk profile for this vulnerable population.
The most frequently reported antihypertensive medication classes in this study were ACE inhibitors (36.8%), diuretics (34.9%), calcium-channel blockers (26.3%) and Beta-Blockers (24.3%). These findings are similar to those of Vacek and colleagues49 who used Kansas Medicaid data to characterise antihypertensive medication use for adults with ID aged 18-64 years who had prescription claims over one year. For TILDA participants, ACE inhibitors were also the most commonly reported medication used, with diuretics being the fourth most common (23.1%). Although diuretics remain the cornerstone of antihypertension treatment, their dysmetabolic effects may increase the risk of new onset diabetes, particularly when combined with betablockers.37 Given the evidence that diabetes occurs more frequently in people with ID than the general population,21 diuretic use in the treatment of
48 Care providers may administer prescribed medications daily, which may provide some explanation for this finding regarding medication adherence and subsequent effectiveness.
The study has strengths and limitations. Proxy respondents completed just over one third of the interviews, which could have introduced respondent bias. In order to reduce the chances of this from occurring, proxy respondents were required to be family members or key staff members who knew the participant well. In addition, using self-report questionnaires, as was the case in this study, runs the risk of recall bias along with the risk of over and under reporting, particularly if results are reliant on only one measurement. To counteract this and in line with the previously reported TILDA general population study and recommendations
Overall, prevalence was lower than that reported in other studies of people with ID in the Netherlands,10 Sweden21 and the US.11 The differences in findings may reflect that our sample: 1) was drawn from a nationally representative study population of people with ID, 2) was carried out in tandem with the general Irish population study (TILDA) using the same measurement and diagnostic criteria, 3) included objective measurement of blood pressure in persons with all levels of ID, and across various living circumstances including those living in community and independently, and 4) obtained detailed information about treatment with antihypertensive medicines. While further confirmatory studies are needed, a more robust understanding of hypertension prevalence and its management in adults with ID has

of epidemiological studies, independent measures of blood pressure were completed 50 and medication prescription data were double checked. This added to the study’s validity with respect to data on blood pressure prevalence, treatment and control. Further, providing some analyses on those ≥ 50 years facilitated direct comparison with the TILDA general population sample and added value to the study. Conversely, data on medications were not completely transparent and it was difficult to differentiate if beta-blockers were used for dual or other indications, for example migraine and anxiety.

This study provides the most comprehensive information to date on the prevalence, level of awareness, treatment and control of hypertension in older adults with ID in Ireland. In addition, it has facilitated some comparisons between the ID and the general population. Increased population and primary care level interventions to reduce hypertension prevalence and improve awareness, detection and management has been recommended for all adults over 50 years in Ireland.7 This study provides evidence that greater attention to screening in those with severe and profound levels of ID and in those without diabetes is required. Moreover, the findings that when hypertension is diagnosed, people with ID appear to respond particularly well to hypertension treatments should encourage addressing the undertreatment found here.
The findings regarding low levels of awareness of a diagnosis of hypertension in this ID population further supports the prior concern by Janicki and colleagues11 that there may not be sufficient active case finding. Despite the European Society of Cardiology guidelines4 recommending that a total risk assessment, (which includes BP monitoring), be routinely carried out on all adults > 40 years of age, these guidelines have not been implemented in the ID population in Ireland and no such data has been published. Research is therefore required to establish a CVD risk profile for this vulnerable population. Nonetheless, lack of case finding alone does not provide a full explanation for the low rates of objectively established hypertension in adults with ID, despite the high levels of risk factors, as compared to the general population. Given this measured disconnect between risk and prevalence, additional research is needed to understand what protective factors may be present in this population and to further consider the presumed link between obesity, low levels of physical activity (more prevalent in people with ID) and measured/ diagnosed hypertension.
The examination of factors associated with awareness, treatment and control of hypertension, highlights that for persons with ID, their level of ID is an additional important and unique consideration, in that the greater their level of intellectual disability, the lower their level of awareness and treatment. Further, a concurrent diagnosis of diabetes is associated with greater levels of treatment, which raises concerns that those without a diabetes diagnosis, but with hypertension, are less likely to be treated.
• Increase screening for hypertension in individuals with severe/profound levels of ID and in those without diabetes.

Chronic spontaneous urticaria (CSU) is a common but poorly recognised skin condition affecting children and adults with an estimated prevalence of 1%.1 It is characterised by unpredictable eruptions of itchy hives. Swelling of the skin or mucous membranes, known as angioedema is seen in approximately half of all cases. CSU is distressing for patients and is associated with markedly impaired quality of life and psychological comorbidity.2,3 This often neglected disorder has higher point prevalence in females.4

The first-line treatment for CSU is second generation antihistamines. However, a high proportion of patients will not respond to antihistamine treatment even when prescribed at high doses. Omalizumab is a safe and effective monoclonal antibody directed against IgE. It is recommended in CSU that is refractory to high dose antihistamines.7 It is however a high cost medicine that typically requires specific funding approval with in-hospital administration and monitoring, thus demanding administrative and clinical support. In Ireland, patient access to omalizumab in refractory CSU is allocated on a case by case basis in a handful of specialist centres.
LatestUrticariaAdvances in Chronic Spontaneous Urticaria
Despite this, misconceptions are common. Both patients and health care providers can interpret the symptoms of CSU as representing evidence of food allergy. This leads to inappropriate testing for food sensitisation and can result in unnecessarily restricted diets and increased patient anxiety. Time to diagnosis can be prolonged and patients typically report multiple healthcare attendances before a diagnosis is established. In Europe, the mean time to diagnosis is 2-4 years.6

The primary effector cell in CSU is the mast cell. Mast cell degranulation in CSU is multifactorial. Novel mechanisms at play include ‘autoallergy’ whereby IgE is directed against an element of self or by autoimmunity whereby IgG is directed against IgE or its receptor.5 Our improved understanding of underlying pathology has helped us to differentiate this condition from other allergic diseases.

A recent study conducted at St. James’s Hospital revealed the high number of unplanned healthcare attendances seen in patients with CSU when their disease is active.8 Importantly, the study demonstrated a dramatic reduction in unplanned healthcare interactions after commencing omalizumab, with a 98% reduction in ED attendances and a 97.7% reduction in GP attendances. These data suggest that omalizumab, delivered in a specialist centre, may benefit patients with CSU by reducing disease activity and reducing the need for unscheduled care. The transition towards self-administration of omalizumab provides an opportunity for understanding how the delivery of this treatment can be optimised in an Irish setting.9,10 Patient satisfaction

BRIDION INDICATIONS • Reversal of rocuronium (ROC) or vecuronium (VEC) induced neuromuscular block (NMB) in adults. • For routine reversal of ROC-induced block in children and adolescents aged 2 to 17 years.1 CARDIAC ELDERLY RESPIRATORY OBESITY BRIDION® 100 MG/ML SOLUTION FOR INJECTION (Sugammadex) ABRIDGED PRODUCT INFORMATION Refer to Summary of Product Characteristics (SmPC) before prescribing. PRESENTATION Vials of 200mg (2 ml) or 500mg (5 ml). INDICATIONS Reversal of rocuronium (ROC) or vecuronium (VEC) induced neuromuscular (NM) block in adults. For routine reversal of ROC-induced block in children and adolescents aged 2 to 17 years. DOSAGE AND ADMINISTRATION I.V. as a single bolus injection administered rapidly (within 10 seconds), into an existing I.V. line, by/under the supervision of an anaes thetist. Use appropriate technique to monitor recovery of NM block. Dose depends on the level of block to be reversed, not the anaes thetic regimen. Adults: Routine reversal following ROC- or VEC-induced block: • 4 mg/kg if recovery has reached at least 1 2 post-te tanic counts (PTC). Median recovery time (T4/T1 = 0.9) ≅ 3 minutes. • 2 mg/kg if recovery has occurred up to at least T2 following ROC- or VEC-induced block. Median recovery time (T4/T1 = 0.9) ≅ 2 minutes. Median recovery time (T4/T1= 0.9) is slightly faster with ROC- than VEC-induced block. Immediate reversal of ROC-induced block: 16 mg/kg. Median recovery time (T4/T1 = 0.9) ≅ 1.5 minutes when 16 mg/kg is given 3 minutes after a bolus dose of 1.2 mg/kg ROC. Not recommended for immediate reversal of VEC-induced block. Re administration of sugammadex: For post-operative recurrence of block after an initial dose of 2 mg/kg or 4 mg/kg, repeat dose of 4 mg/kg is recommended. Following a second dose of sugammadex, monitor the patient closely to ascertain sustained return of neuro muscular function. Re-administration of ROC or VEC after sugammadex: Up to 4 mg/kg Sugammadex a waiting time of 5 minutes for re-use of 1.2 mg/kg ROC; 4 hours waiting time for re-use of 0.6 mg/kg ROC or 0.1 mg/kg VEC. With ROC onset of NM block may be pro longed and duration of NM block may shortened. After immediate reversal, 16 mg/kg sugammadex, a waiting time of 24 hours is rec ommended. See SPC for patients with mild or moderate renal impairment. Special populations: Renal impairment: For mild and mod erate renal impairment use adult dose. Not recommended in severe renal impairment (including patients requiring dialysis). Elderly: Use adult dose although recovery times are slower. Obese: In obese patients, including morbidly obese patients (body mass index ≥ 40 kg/m2), adult dose based on actual body weight. Hepatic impairment: Caution in patients with severe hepatic impairment, or impair ment with coagulopathy. Children and adolescents (2 17 years): 2 mg/kg for routine reversal of ROC-induced block at T2. Not recom mended in other routine reversal situations. Not recommended for Immediate reversal. May be diluted for accuracy of dose. Term newborn infants and infants: Not recommended. CONTRA-INDICATIONS Hypersensitivity to sugammadex or to any excipients. PRE

PREGNANCY AND LACTATION Pregnancy and Lactation: Caution in pregnant women. A decision must be made whether to discontinue breast-feeding or to discontinue/abstain from sugammadex therapy, taking into account the benefit of breast feeding for the child and the benefit of therapy for the woman. The effects on human fertility have not been investigated. SIDE EFFECTS Refer to SmPC for complete informa tion on side effects. Common (≥ 1/100 to < 1/10): Anaesthetic complications including movement of limbs or body or coughing during anaesthesia, grimacing, or suckling on the endotracheal tube, airway complication of anaesthesia, procedural hypertension and pro cedural complication. Uncommon (≥ 1/1,000 to < 1/100): Hypersensitivity reactions, including anaphylaxis, have occurred in some pa tients and volunteers. Other less common and rarely reported side effects are listed in the SmPC. In clinical studies with subjects treated with rocuronium or vecuronium, where sugammadex was administered using a dose labelled for the depth of neuromuscular blockade, an incidence of 0.2% was observed for recurrence of neuromuscular blockade as based on neuromuscular monitoring or clinical evidence. The use of lower than recommended doses may lead to an increased risk of recurrence of neuromuscular blockade after initial reversal and is not recommended. HANDLING See SmPC for details of compatability with infusion solutions. Physical in compatibility has been reported with verapamil, ondansetron and ranitidine. PACKAGE QUANTITIES 10 vials of 2 ml, 10 vials of 5 ml.
CAUTIONS AND WARNINGS Ventilatory support is mandatory for patients until adequate spontaneous respiration is restored follow ing reversal of block. Should block reoccur following extubation, adequate ventilation should be provided. The use of lower than rec ommended doses may lead to an increased risk of neuromuscular blockade after an initial reversal and is not recommended. Caution should be exercised when considering the use of sugammadex in patients receiving anticoagulation for a pre-existing or co-morbid condition. An increased risk of bleeding cannot be excluded in patients with hereditary vitamin K dependent clotting factor deficien cies; with pre-existing coagulopathies; on coumarin derivatives and at an INR above 3.5; using coagulants who receive a dose of 16mg/ kg sugammadex. If re administration of ROC or VEC is required in patients with mild or moderate renal impairment after routine sugam madex reversal a waiting time for re-use of 0.6 mg/kg ROC or 0.1 mg/kg VEC should be 24 hours. If a shorter waiting time is required, the ROC dose for a new NM blockade should be 1.2 mg/kg within 30 minutes after Sugammadex administration. For re-administration of ROC or VEC after immediate reversal a waiting time of 24 hours is recommended. If neuromuscular block is required before the recommended waiting time has passed, a nonsteroidal neuromuscular blocking agent should be used. The use in patients with severe renal impairment is not recommended including those requiring dialysis. If neuromuscular block is reversed, while anaesthesia is continued, additional doses of anaesthetic and/or opioid should be given as clinically indicated. Marked bradycardia with cardiac arrest have been observed within minutes after administration, closely monitor patients for hemodynamic changes during and after reversal. Treat with anti-cholinergic agents such as atropine if clinically significant bradycardia observed. Sugammadex has not been
investigated in patients receiving ROC or VEC in the ICU setting. Do not use sugammadex to reverse block induced by nonsteroidal blockers such as succinylcholine or benzylisoquinolinium compounds, or steroidal blockers other than ROC or VEC. Conditions asso ciated with prolonged circulation time such as cardiovascular disease, old age, or oedematous state may cause longer recovery times. Be prepared for possible drug hypersensitivity reactions. This medicinal product contains up to 9.7 mg sodium per ml, equivalent to 0.5 % of the WHO recommended maximum daily intake of 2 g sodium for an adult. OVERDOSE No dose related adverse events nor serious adverse events were reported. Sugammadex can be removed using haemodialysis with a high flux filter. INTERACTIONS To remifene and fusidic acid may displace rocuronium or vecuronium from sugammadex and delay recovery (no clinically relevant cap turing interactions are expected). Interaction of sugammadex with hormonal contraceptives may lead to a decrease in progesterone exposure equivalent to one missed daily dose of oral contraceptive (no displacement interactions are expected). In general sugamma dex does not interfere with laboratory tests, with the possible exception of the serum progesterone assay where interference is ob served at sugammadex plasma concentrations of 100 μg/ml plasma. In a study doses of 4 mg/kg and 16 mg/kg sugammadex resulted in maximum mean prolongations of the activated partial thromboplastin time by 17 and 22% respectively and prothrombin time by 11% and 22% respectively. These were of short duration (≤ 30 minutes). In in vitro experiments pharmacodynamic interaction was noted with vitamin K antagonists, unfractionated heparin, low molecular weight heparinoids, rivaroxaban and dabigatran.
Adverse events should be reported. Reporting forms and information can be found at www.hpra.ie. Adverse events should also be reported to MSD (Tel: 01-299 8700)

The choice of radiotherapy or surgery depends on multiple factors, but some generalisations can be made. Tumours in the oral cavity are primarily treated with surgical excision, often with a neck dissection. Early vocal cord tumour can be excised by Laser, whilst patients presenting with T4 or recurrent disease in the larynx will require a laryngectomy. Curative radiotherapy, frequently combined with chemotherapy, can be employed with organ preservation as a goal or to decrease the morbidity associated with surgical excision, when survival outcomes are similar or superior to surgery. This included many laryngeal tumours, nasopharyngeal, hypopharyngeal and oropharyngeal tumours. Radiotherapy is also often given in the adjuvant setting, post-surgical resection. Radiotherapy is usually given over a period of 6-7 weeks, and in general is well tolerated. Adverse effects such a dry mouth are common, but more severe side effects necessitating NG or PEG feeding is sometimes required. When radiotherapy is utilized in
This may be a slight overestimation patients managed by Head and Neck MDTs due to the inclusion of all Thyroid cancers, but it also does not include Sarcoma of the Head and Neck and other miscellaneous malignancies. However in reality it is likely an underestimation as from audit data from the St. James’s Head and Neck MDT suggests that 10% of the workload can be attributed to Cutaneous Malignancy.

Recent advances in the field include preoperative digital planning of resections requiring bony reconstruction. This allows the ablative and reconstructive surgeon to plan the surgery in advance, and exact guides to be made that allow both teams to operate concurrently. This shortens operative time, and has been shown to improve outcomes for the patients. Robotic surgery, specifically trans oral robotic surgery (TORS), allowed larger tumours in the oropharynx to be excised per-orum eliminating the need for lip split and mandibulotomy associated with traditional surgery. Studies show some promise, but again, it appears that the proven treatment modality of Radiotherapy is safer, and remains the standard of care.

The patients that undergo major surgical resections, and thus account for the majority of patients in hospital, fall into two broad categories- those undergoing an oral cavity or oropharyngeal resection often with a free flap reconstruction, or those undergoing a laryngectomy or pharyngolaryngectomy. Patients undergoing either of these procedures will require extensive preoperative management and post-operative rehabilitation. A large number of allied health professionals are therefore crucial to the patients care. These include Speech and Language therapist, Dieticians, Physiotherapists, and social workers. Patients are also seen by restorative dentists, before both surgery and radiotherapy, and often in the post-operative setting. Clinical nurse specialist are also essential in the management of such patients, guiding them through what can be a daunting journey, and co-ordinating their complex care. A tracheostomy may be required temporarily, and therefore specialist nurses are invaluable in managing such patients. Patients can be admitted for a number of weeks, often including an ICU stay postoperatively. The rehabilitation of swallow and speech can be challenging depending on the extent of surgical excision, but even those post laryngectomy can re-establish intelligible speech.

of studies have been carried out to examine the safety in deescalating these treatments, either through decreasing the dose of radiotherapy or substituting chemotherapy for a less toxic immunotherapy, these studies have thus far failed to demonstrate improved outcomes. Therefore, although HPV+ve patients may have a lower overall stage than their HPV-ve counterparts, they will, at present, receive the same treatment paradigms.

In Ireland, no screening program was established, but we have still seen a large increase in incidence, for similar reasons. Thyroid nodules are often seen incidentally on imaging for other indications, such as MRI spines and CT chests. These are then investigated and for the same reasons as above, malignancies may be diagnosed. It can be challenging to establish whether a thyroid nodule is benign or

with adverse histological features may require total or completion thyroidectomy and adjuvant radioactive iodine. Medullary thyroid cancer is a challenging and thankfully uncommon malignancy, that can be familial in origin and is associated with MEN2a and MEN2b. Children with these syndromes require a thyroidectomy at a very young age, to prevent the development of medullary thyroid cancer. Finally Anaplastic thyroid cancer is one of the most aggressive solid organ malignancies in humans, with a median survival measured in just a number of months. Patients usually present with inoperable tumours, but fortunately as few as 10 patients a years are diagnosed with these tumours in Ireland.
This can be explained by a number of autopsy studies which demonstrated that up to a third of patients, with no prior history of thyroid disease, had a malignancy at post mortem. The authors of one study suggested that this may be as high as 100%, had the thyroids been dissected to extremely sizes. This implies that we may all have tiny thyroid cancers, that are subclinical and in the vast majority of times will likely remain so. This is supported by a number of studies that have successfully observed small biopsy proven thyroid cancers, with Ito in Japan accumulating over 1000 patients with up to 1cm tumours.

This has cumulated in HPV mediated OPSCC being recognised as a separate entity in the 8th AJCC staging manual published in 2018. An audit of Irish cancer centres from 2014-2018 demonstrated that 46% of OPSCC were HPV+ve. This is inline with many developed countries, although some studies have shown a much higher percentage. Audit data from St. James’s Hospital in 2020 revealed that 41 of 55 OPSCC patients (74.5%) were HPV positive.
It includes the tonsils, the soft palate, the posterior pharyngeal wall and the back or base of tongue ( this is part of the tongue that can't be easily seen, and is much more like the tonsils than the muscular front or anterior two thirds of the Traditionally,tongue).likemost Head and Neck Cancers, the major risk factor for oropharyngeal cancer were cigarette smoking, excess alcohol consumption, advanced age and male gender. Although a link between Head and Neck Cancer and Human Papilloma Virus (HPV) has been known since the 1980s, it was only when rapidly increasing incidences in OPSCC were noted in patients without traditional risk factors in the 2000s, that HPV as a causative agent for OPSCC was more widely researched. A landmark paper by Ang et al. in 2010 demonstrated that HPV positive OPSCC who were nonsmokers had a vastly superior (93.5%) 3 year survival, compared to HPV negative OPSCC smokers (41.6% 3 year survival). Further studies corroborated these finding and a distinct carcinogenic pathway was identified.
this has not meant that there has been a change in our standard of care in the management of HPV+ve OPSCC, which is generally either radiotherapy alone, or most often concomitant chemotherapy and radiotherapy. Although a number
Patients with oropharyngeal cancer typically present with unilateral symptoms, of persistent sore throat, for more than three weeks, with referred otalgia. A unilateral enlarged or ulcerated tonsil can often be seen. Patients with HPV+ve OPSCC often present with large cystic neck nodes, and relatively small primary tumours. In older staging systems, a patient with this clinical picture, for example T2N2bM0, would be classified as Stage IVa, and HPVve OPSCC would still be staged this way. However with the new AJCC staging, a patient with the same clinical picture, and HPV+ve, would be T2N1M0, and classified as Stage Unfortunately,I.

One vial of 4ml concentrate contains 100mg pemetrexed. One vial of 20ml concentrate contains 500mg pemetrexed. One vial of 40ml concentrate contains 1,000mg pemetrexed. Excipients with known effect – 4ml vial - 964mg hydroxypropylbetadex, 20ml vial – 4820mg hydroxypropylbetadex, 40ml vial – 9640mg hydroxypropylbetadex. Indications: In combination with cisplatin - treatment of chemotherapy naïve patients with unresectable malignant pleural mesothelioma, first line treatment of locally advanced or metastatic non-small cell lung cancer other than predominantly squamous cell histology. Monotherapy – Maintenance treatment of locally advanced or metastatic non-small cell lung cancer other than predominantly squamous cell histology in patients whose disease has not progressed immediately following platinum-based chemotherapy, second line treatment of locally advanced or metastatic non-small cell lung cancer other than predominantly squamous cell histology. Posology and method of administration: Only administer under the supervision of a physician qualified in the use of anti-cancer chemotherapy. Administer as an intravenous infusion over 10 minutes on the first day of each 21-day cycle. See SmPC for further information on handling, administering and dilution. In combination with cisplatin – Recommended dose is 500mg/m2 of body surface area (BSA) administered as an intravenous infusion over 10 minutes on the first day of each 21-day cycle. Recommended dose of cisplatin is 75mg/m2 BSA infused over two hours approximately 30 minutes after completion of the pemetrexed infusion on the first day of each 21-day cycle. Patients must receive adequate anti-emetic treatment and appropriate hydration prior to and/or after receiving cisplatin (see also cisplatin SmPC). As single agent – In the treatment of non-small cell lung cancer after prior chemotherapy, recommended dose is 500mg/m2 BSA administered as an intravenous infusion over 10 minutes on the first day of each 21-day cycle. Pre-medication regimen: To reduce the incidence and severity of skin reactions, a corticosteroid should be given the day prior to, on the day of, and the day after pemetrexed administration. Corticosteroid should be equivalent to 4mg of dexamethasone orally twice daily. Patients must also receive vitamin supplementation; oral folic acid or a multivitamin containing folic acid (350 to 1000 micrograms) on a daily basis. At least five doses of folic acid must be taken during the seven days preceding the first dose of pemetrexed and dosing must continue during the full course of therapy and for 21 days after the last dose of pemetrexed. Patients must also receive an intramuscular injection of vitamin B12 (1000 micrograms) in the week preceding the first dose of pemetrexed and once every three cycles thereafter. Subsequent vitamin B12 injections may be given on the same day as pemetrexed. Monitoring: Before each dose complete blood count including differential white cell count (WCC) and platelet count. Prior to each chemotherapy administration blood chemistry tests should be collected to evaluate renal and hepatic function. Before the start of any cycle of chemotherapy, patients are required to have absolute neutrophil count (ANC) ≥ 1500 cells/mm3 and platelets ≥ 100,000 cells/mm3. Creatinine clearance should be ≥ 45 ml/min. Total bilirubin should be ≤ 1.5 times upper limit of normal. Alkaline phosphatase (AP), aspartate aminotransferase (AST or SGOT) and alanine aminotransferase (ALT or SGPT) should be ≤ 3 times upper limit of normal. AP, AST and ALT ≤ 5 times upper limit of normal is acceptable if liver has tumour involvement. Dose adjustments: At the start of a subsequent cycle should be based on nadir haematologic counts or maximum non-haematologic toxicity from the preceding cycle of therapy. Treatment may be delayed to allow sufficient time for recovery. Upon recovery patients should be retreated using the guidelines as follows, which are applicable for pemetrexed Fresenius Kabi used as single agent or in combination with cisplatin. Haematologic toxicities (dose modify both pemetrexed and cisplatin) – Nadir ANC < 500/mm3 and nadir platelets ≥ 50,000/mm3, or nadir platelets < 50,000/mm3 regardless of nadir ANC: 75% of previous dose. Nadir platelets < 50,000/mm3 with bleeding regardless of nadir ANC: 50% of previous dose. Non-haematologic toxicities ≥ Grade 3 (excluding neurotoxicity) - pemetrexed Fresenius Kabi should be withheld until resolution to less than or equal to the patient’s pre-therapy value. Treatment should be resumed accordingly – Any grade 3 or 4 toxicities except mucositis, or any diarrhoea requiring hospitalisation or grade 3 or 4 diarrhoea: 75% of previous dose (mg/m2) of pemetrexed and cisplatin. Grade 3 or 4 mucositis: 50% of previous pemetrexed dose (mg/m2) and 100% of previous cisplatin dose (mg/m2). Neurotoxicity – Patients should discontinue therapy if Grade 3 or 4 neurotoxicity is observed. CTC Grade 0-1: 100% of previous pemetrexed and cisplatin dose (mg/m2). CTC Grade 2: 100% of previous pemetrexed dose (mg/m2) and 50% of previous cisplatin dose (mg/m2). Discontinue treatment with pemetrexed Fresenius Kabi if a patient experiences any haematologic or non-haematologic Grade 3 or 4 toxicity after 2 dose reductions or immediately if Grade 3 or 4 neurotoxicity is observed. Elderly – No dose reductions other than those recommended for all patients are necessary.

ischemic heart diseases and elevated intracranial pressure. Reduce dose if heart rhythm disorders occur during treatment. Cardiac arrhythmias may arise when used in conjunction with cardiac sensitizing agents and may be more likely in patients with hypoxia or hypercarbia. Elderly patients may be especially sensitive to the effects of noradrenaline. Not recommended in children. Where indicated, appropriate replacement therapy of blood or fluid together with adoption of the supine position with elevation of the legs, must be instituted and maintained prior to and/or during therapy with noradrenaline. During infusion, record blood pressure every two minutes from the time the administration started until the desired blood pressure is obtained and then every five minutes thereafter if infusion continued. Constantly watch flow rate and never leave patient unattended. Hypertension may eventually lead to acute pulmonary oedema, arrhythmia or cardiac arrest. Caution in patients receiving pressor amines with chloroform, enflurane or other halogenated anaesthetics (may cause serious cardiac arrhythmias) or any other cardiac sensitising agent or in patients who exhibit profound hypoxia or hypercarbia. Extreme caution in patients receiving monoamine oxidase inhibitors or within 14 days of cessation of such therapy and in patients receiving tricyclic antidepressants, adrenergic- serotoninergic drugs or linezolid. Overdoses or conventional doses in hypersensitive persons may cause severe hypertension with violent headache, photophobia, stabbing retrosternal pain, pallor, intense sweating and vomiting. The infusion site should be checked frequently for free flow. Care should be taken to avoid extravasation of noradrenaline tartrate into the tissues, as local necrosis might ensue due to the vasoconstrictive action of the drug (see SmPC for antidote for extravasation ischaemia). Blanching along the course of the infused vein warrants consideration of changing infusion site at intervals. Avoid administration via the veins of the leg in elderly patients or in those suffering from occlusive vascular diseases. Noradrenaline interacts with other medicinal products; some combinations are inadvisable or require additional precautions and close medical supervision – see SmPC. Undesirable effects: Anxiety, insomnia, confusion, weakness, psychotic state, transient headache, tremor, acute glaucoma, bradycardia, arrhythmia, electrocardiogram change, tachycardia, cardiogenic shock, stress cardiomyopathy, palpitations, increase in the contractility of the cardiac muscle resulting from the beta- adrenergic effect on the heart (inotrope and chronotrope), acute cardiac insufficiency, hypertension, peripheral ischaemia including gangrene of the extremities, plasma volume depletion with prolonged use, dyspnoea, respiratory insufficiency or difficulty, nausea, vomiting, paleness, scarification of the skin, bluish skin colour, hot flushes or skin redness, skin rash, hives or itching, retention of urine, extravasation, necrosis at injection site.

Renal impairment – (Standard Cockcroft and Gault formula or GFR measured Tc99m-DPTA serum clearance method). In clinical studies patients with creatinine clearance of ≥ 45ml/min required no dose adjustments other than those recommended for all patients. Not recommended in patients with creatinine clearance below 45ml/min. Hepatic impairment – Patients with hepatic impairment have not been specifically studied. Contraindications: Hypersensitivity to the active substance or to any of the excipients, breast-feeding, concomitant yellow fever vaccine. Special warnings and precautions for use: Monitor patients for myelosuppression. Pemetrexed should not be given until ANC returns to ≥ 1500 cells/mm3 and platelet count to ≥ 100,000 cells/mm3. Dose reductions for subsequent cycles based on nadir ANC, platelet count and maximum non-haematologic toxicity seen from previous cycle. All patients must be instructed to take folic acid and vitamin B12 as a prophylactic measure to reduce treatment-related toxicity. Pre-treatment with dexamethasone (or equivalent) can reduce the incidence and severity of skin reactions. Not recommended in patients with creatinine clearance of < 45ml/min. Patients with mild to moderate renal insufficiency (creatinine clearance 45-79ml/min) should avoid taking NSAIDs, or acetylsalicylic acid (> 1.3g daily) for 2 days before, on the day of, and 2 days following pemetrexed administration. In patients with mild to moderate renal insufficiency NSAIDs with long elimination half-lives should be interrupted for at least 5 days prior to, on the day of, and at least 2 days following pemetrexed administration. Patients should be regularly monitored for acute tubular necrosis, decreased renal function and signs and symptoms of nephrogenic diabetes insipidus. Drainage of third space fluid collection prior to pemetrexed treatment should be considered but may not be necessary. Patients should receive adequate antiemetic treatment and appropriate hydration prior to and/or after receiving treatment. Serious cardiovascular and cerebrovascular events have been uncommonly reported during clinical studies with pemetrexed, usually when given in combination with another cytotoxic agent. Concomitant use of live attenuated vaccines is not recommended. Sexually mature males are advised not to father a child during treatment and up to 6 months thereafter. Contraceptive measures or abstinence are recommended. Possibility of irreversible infertility; men advised to seek counselling on sperm storage before starting treatment. Women of childbearing potential must use effective contraception during treatment with pemetrexed. Cases of radiation pneumonitis reported in patients treated with radiation either prior, during or subsequent to pemetrexed therapy; particular attention should be paid to these patients and caution with other radiosensitising agents. Cases of radiation recall reported in patients who received radiotherapy weeks or years previously. Accumulation of cyclodextrins may occur in patients with moderate to severe renal dysfunction. May cause fatigue, patients should be cautioned against driving or operating machinery if this occurs.

ABBREVIATED PRESCRIBING INFORMATION: Consult the Summary of Product Characteristics for further information. Additional information is available upon request. Noradrenaline (Norepinephrine) Kabi 1mg/ml concentrate for solution for infusion. Active ingredient: 1ml concentrate for solution for infusion contains 1mg noradrenaline (norepinephrine) base equivalent to 2mg noradrenaline (norepinephrine) tartrate. Contains 3.4mg sodium per ml. Indications: In adults for use as an emergency measure in the restoration of blood pressure in cases of acute hypotension. Posology and method of administration: When diluted as recommended, each litre contains 40mg noradrenaline base equivalent to 80mg noradrenaline tartrate. If dilutions other than 40mg per litre are used, check infusion rate calculation carefully before starting treatment. Initial rate of infusion – 10-20ml/hour (0.16-0.32ml/min); equivalent to 0.4-0.8mg/hour noradrenaline base. Lower initial infusion rate of 5ml/hour (0.08ml/min); equivalent to 0.2mg/hour noradrenaline base may be preferred. Titration of dose – Once infusion has been established, titrate dose in steps of 0.05-0.1mcg/kg/min of noradrenaline base according to pressor effect observed (see SmPC for details). Continue infusion until adequate blood pressure and tissue perfusion maintained without therapy. Carefully monitor patient. Should only be administered by healthcare professionals familiar with use of noradrenaline and with appropriate monitoring facilities. Avoid abrupt infusion withdrawal; reduce infusion gradually. No experience in treatment of hepatic or renal impairment. Dose selection for an elderly patient should be cautious, starting at the low end of the dosing range. Safety and efficacy in patients less than 18 years old has not been established. Method of administration – Intravenous use only after dilution. Infuse at a controlled rate using either syringe pump, infusion pump or drip counter. Administer via a central venous catheter. If not using a central venous catheter administer into a large vein whenever possible, particularly an antecubital vein to minimize risk of ischemic necrosis. Avoid catheter tie-in technique if possible. Contraindications: Hypersensitivity to the active substance or to any of the excipients, hypotension due to blood volume deficit. Do not use with cyclopropane and halothane anaesthetics as this may cause serious cardiac arrhythmias including ventricular fibrillation. Special warnings and precautions for use: Do not use undiluted. Contraindicated in patients who are hypotensive from blood volume deficits except as an emergency measure to maintain coronary and cerebral artery perfusion until blood volume replacement therapy can be completed. Should only be used in conjunction with appropriate blood volume replacement. If whole blood or blood plasma is indicated to increase blood volume, administer separately (e.g. use Y-tubing, individual containers). Prolonged administration may result in plasma volume depletion which should be continuously corrected by appropriate fluid and electrolyte replacement therapy. Frequently check blood pressure and rate of flow to avoid hypertension. Particular caution in patients with coronary, mesenteric or peripheral vascular thrombosis, hypotension following myocardial infarction, angina (particularly Prinzmetal’s variant angina), diabetes, hypertension or hyperthyroidism, major left ventricular dysfunction associated with acute hypotension (supportive therapy should be initiated simultaneously with diagnostic evaluation; reserve noradrenaline for patients with cardiogenic shock and refractory hypotension, in particular those without elevated systemic vascular resistance), liver failure, severe renal dysfunction,

While all physician associate students hold a foundation degree in health science or a sciencerelated area, they come from a diverse range of backgrounds from healthcare to academia.
AbbVie has announced the availability in Ireland of upadacitinib, an oral, selective and reversible Janus Kinase (JAK) inhibitor, for the treatment of moderate to severe atopic dermatitis in adults and adolescents 12 years and older who are candidates for systemic therapy. This is now available to prescribe via the HSE-Medicines Management Programme under a HSE-Managed Access Protocol.
He stated: “Eczema is a chronic relapsing inflammatory skin disease, characterised by intense itch, dry skin and typically distributed skin lesions. The burden experienced by patients and their care-givers is significant, with chronic itch and sleep disturbance, negatively affecting overall quality of life.
The EC approval was supported by data from one of the largest registrational Phase 3 programs in atopic dermatitis with more than 2,500 adults and adolescents with moderate to severe disease These studies evaluated the efficacy and safety of upadacitinib monotherapy (Measure Up 1 [MU1] and Measure Up 2 [MU2]) and with topical corticosteroids (AD Up [AU]) compared to placebo. In all three studies, the co-primary endpoints were at least a 75 percent improvement in the Eczema Area and Severity Index (EASI 75) and validated Investigator's Global Assessment for Atopic Dermatitis (vIGA-AD) score of 0/1 (clear or almost clear) at week 16.

Day will encourage the public to take action to look after their kidney health. We are pleased that the National Renal Office is endorsing the campaign and are delighted to be working closely with Diabetes Ireland to highlight the importance of kidney health screening as diabetes is one of the main risk factors for chronic kidney disease”.
Risk factors towards developing Chronic Kidney Disease (CKD)

World Kidney Day which was celebrated on 10th March 2022 aims to bridge the knowledge gap to better kidney care. To mark World Kidney Day, the Irish Kidney Association (IKA), in association with the HSE’s National Renal Office (NRO), ran an awareness campaign to highlight the importance of early screening for Chronic Kidney Disease (CKD). Diabetes Ireland is supporting the campaign to ensure that the core messaging about looking after your kidneys reaches one of the most common at-risk groups, i.e., people living with diabetes.
amongst other health conditions. The IKA’s campaign aims to highlight that it is possible to prevent or slow down the progression of kidney disease through lifestyle changes and medication and that it all starts with simple blood and urine tests done through your GP to measure and monitor your kidney health.
The success of the campaign is also reliant on the valued support of healthcare professionals including GPs and Pharmacists. The Irish Pharmacy Union is supporting the campaign through sharing its message on its digital and print platforms. Some independent pharmacy chains are also promoting the campaign to their customers. The collaboration between all these interest groups in supporting the campaign is an indicator of the importance of monitoring kidney health.

Chronic Kidney Disease (CKD) significantly increases the risk of negative outcomes in people living with diabetes, cardiovascular disease and high blood pressure
Speaking in advance of World Kidney Day 2022, Ms. Carol Moore, Chief Executive, Irish Kidney Association said, “as there is no public health screening programme for kidney disease in Ireland, we hope that the ‘Counting On You’ awareness campaign to mark World Kidney
The tagline message for the Irish Kidney Association’s campaign is ‘We’re Counting on You’. This represents the importance for the public to be proactive in managing their kidney health and that they are being ‘counted on’ to get a simple blood test and urine test which will reveal their kidney function ‘numbers’. These ‘numbers’ will represent how well the kidneys are functioning in filtering blood and removing waste from the body. If Chronic Kidney Disease (CKD) is detected early enough, its progression, through the five stages of CKD, can be slowed down supporting better patient outcomes.
Patients attending the event included Rachel O'Hora who lives in Seapoint Dublin (a native of Mayo) who is awaiting a combined kidney and pancreas transplant and Raymond O'Brien, from Salthill in Galway, who like Rachel is also living with Type 1 diabetes but has undergone a kidney transplant. He attended the photocall with his wife Ethna and three children including 9 year old twins Jack and Amy and 11 year old Isabel.

In backing the Irish Kidney Association’s campaign for kidney health screening Prof. George Mellotte, the National Clinical Lead for Renal Services stated, “People with Chronic Kidney Disease are medically vulnerable to the effects of high blood pressure, diabetes and cardiovascular disease. It is important that people with Chronic Kidney Disease are identified so that they can seek the appropriate treatment in a timely manner".

The evidence supporting the efficacy and safety of tralokinumab comes from four randomised, multicentre, doubleblind, placebo-controlled, phase III studies: ECZTRA 1, ECZTRA 2, ECZTRA 3 in patients with moderate-to-severe atopic dermatitis and ECZTRA 7 in patients with severe disease.4,5,6
Tralokinumab is the first high affinity, human monoclonal antibody developed to specifically bind to and inhibit the IL-13 cytokine in adult patients with uncontrolled moderate-tosevere atopic dermatitis who are candidates for systemic therapy.1,2 Tralokinumab is available in a 150 mg/mL prefilled syringe for subcutaneous injection with an initial dose of 600 mg followed by 300 mg every other week.7 Tralokinumab can be used with or without topical corticosteroids (TCS).7
This medicine is indicated for symptomatic treatment of acute attacks of hereditary angioedema (HAE) in adults, adolescents and children aged 2 years and older, with C1-esterase-inhibitor deficiency.

The European Commission has granted marketing authorization in the European Union (EU) for finerenone under the brand name Kerendia®. Kerendia® (10 mg or 20 mg), a non-steroidal, selective mineralocorticoid receptor antagonist, is indicated for the treatment of chronic kidney disease (stage 3 and 4 with albuminuria) associated with type 2 diabetes in adults.
“The worrying reality is that chronic kidney disease in type 2 diabetes is the leading cause of end-stage kidney disease, which ultimately means that the kidneys no longer support the body’s needs and patients need dialysis or a kidney transplant to stay alive. Early intervention is associated with a better prognosis, and it is key to prevent further end-organ damage by reducing the risk of kidney function loss,” said Dr. Michael Devoy, Chief Medical Officer and Head of Medical Affairs and Pharmacovigilance at Bayer’s theEUThekidneycardiovascularpatientstooffersDivision.“ThePharmaceuticalsapprovalofKerendiaphysiciansanewpathprotectthesevulnerablebyreducingtheirriskofeventsanddelayingdiseaseprogression.”approvalofKerendiaintheisbasedontheresultsofpivotalPhaseIIIFIDELIO-

Atopic Dermatitis is much more than a skin condition, it can have a profound effect on the emotional and psychological wellbeing of patients, as well as on their physical health,” said Professor Alan Irvine, Consultant Dermatologist, School of Medicine Trinity College Dublin.
These data demonstrated that treatment with esketamine nasal spray plus a newly initiated oral antidepressant was associated with a greater reduction in depressive symptoms compared to a newly initiated oral antidepressant plus placebo nasal spray, in adult patients (18-64 years), with the onset of efficacy as early as Day 2.6 Approximately 70 percent of esketaminetreated patients responded to treatment, with a ≥50 percent symptom reduction. Furthermore, approximately half of all treated patients achieved remission at the end of the 4 week studies.1 Continued treatment with esketamine nasal spray plus oral antidepressant reduced the risk of relapse by 70 percent among patients with stable response and by 51 percent in patients in stable remission, compared to continuing treatment with oral antidepressant alone.9

Neil Johnson, CEO of Croí, Irish patient organisation fighting against heart disease and stroke, and Executive Director of the Global Heart Hub says, “It’s estimated that over 60 million people worldwide are living with heart failure. This complex medical condition very often has a devastating impact on quality of life: physically, emotionally and even financially for those who can no longer work. New treatments for a heretofore underserved population of patients which can improve outcomes and reduce hospital admissions is just great news for patients. The impact of new and emerging treatments on quality of life, from a patient and carer perspective, cannot be overstated because they provide hope and comfort in the knowledge that heart failure can be treated. This in turn has an enormously positive impact on overall mental health and wellbeing by decreasing anxiety, stress and worry.”

prophylactic zoster vaccinations prior to starting therapy, in agreement with current immunisation guidelines. Malignancy: Immunomodulatory therapies may increase the risk of malignancies including lymphoma and nonmelanoma skin cancer in RA patients. Malignancies were observed in clinical studies. Periodic skin examination recommended for patients who are at increased risk for skin cancer. See SmPC for full details. Haematological abnormalities: Do not start therapy if Absolute Neutrophil Count <1 x 109 cells/L, Absolute Lymphocyte Count <0.5 x 109 cells/L and Hb <8 g/dL. Monitor patients and temporarily stop therapy if abnormal haematological parameters as specified are detected during routine patient management. Diverticulitis: Events of diverticulitis have been reported in clinical trials and post-marketing. Upadacitinib should be used with caution in patients with diverticular disease and especially in patients chronically treated with concomitant medications associated with an increased risk of diverticulitis. Patients presenting with new onset abdominal signs and symptoms should be evaluated promptly for early identification of diverticulitis to prevent gastrointestinal perforation. Cardiovascular Risk: RA patients have an increased risk for cardiovascular disorders. Manage patient’s risk factors for e.g. hypertension, hyperlipidaemia as per usual standard of care. Lipids: Monitor total cholesterol, low-density lipoprotein (LDL) and high-density lipoprotein (HDL) at 12 weeks and thereafter according to international guidelines. Elevated LDL in clinical trials decreased to pre-treatment levels in response to statin therapy, although evidence is limited. The effect of these lipid parameter elevations on cardiovascular morbidity and mortality has not been determined. Hepatic transaminase elevations: Monitor liver enzymes at baseline and thereafter according to routine patient management. Prompt investigation of the cause of liver enzyme elevation is recommended to identify potential cases of drug-induced liver injury. In such cases therapy should be interrupted until this diagnosis is excluded. Venous thromboembolism: Deep vein thrombosis (DVT) and pulmonary embolism (PE) have been reported in patients receiving JAKi, including upadacitinib. Use therapy with caution in patients at high risk for DVT/PE. Risk factors should be determined by patients age, obesity and medical history of DVT/PE, patients undergoing major surgery and prolonged immobilisation. If clinical features of DVT/PE occur discontinue therapy, evaluate and treat promptly. INTERACTIONS: Upadacitinib is metabolised mainly by CYP3A4 and plasma exposures may be affected by CYP3A4 inhibitors or inducers. Upadacitinib 15 mg once daily should be used with caution in patients receiving chronic treatment with strong CYP3A4 inhibitors. Upadacitinib 30 mg once daily dose is not recommended for patients receiving chronic treatment with strong CYP3A4 inhibitors. See SmPC for full details. FERTILITY, PREGNANCY AND LACTATION: Upadacitinib is contraindicated during pregnancy. Women of childbearing potential should be advised to use effective contraception during treatment and for 4 weeks the and/or their parents/caregivers while taking upadacitinib. of on fertility has not been

PRESCRIBING INFORMATION (PI) RINVOQ® (upadacitinib) 15 mg and 30mg prolonged-release tablets. Refer to Summary of Product Characteristics (SmPC) for full prescribing information. PRESENTATION: Each 15 mg prolonged-release tablet contains upadacitinib hemihydrate, equivalent to 15mg of upadacitinib. Each 30mg prolonged-release tablet contains upadacitinib hemihydrate, equivalent to 30 mg of upadacitinib. INDICATION: Treatment of moderate to severe active rheumatoid arthritis (RA) and active psoriatic arthritis (PsA) in adult patients who have responded inadequately to, or who are intolerant to one or more disease-modifying anti-rheumatic drugs (DMARDs). RINVOQ may be used as monotherapy or in combination with methotrexate. Treatment of active ankylosing spondylitis (AS) in adult patients who have responded inadequately to conventional therapy. Treatment of moderate to severe atopic dermatitis (AD) in adults and adolescents 12 years and older who are candidates for systemic therapy. DOSAGE AND ADMINISTRATION: Intended for use under guidance and supervision of a physician experienced in diagnosis and treatment of conditions for which upadacitinib is indicated. Dosage: RA, PsA and AS: The recommended oral dose is 15mg once daily. Consideration should be given to discontinuing treatment in patients with AS who have shown no clinical response after 16 weeks of treatment. Some patients with initial partial response may subsequently improve with continued treatment beyond 16 weeks. AD (adults): The recommended oral dose is 15 mg or 30 mg once daily based on individual patient presentation. 30 mg once daily dose may be appropriate for patients with high disease burden and for patients with an inadequate response to 15 mg once daily. The lowest effective dose for maintenance should be considered. For patients ≥ 65 years of age, the recommended dose is 15mg once daily. AD (adolescents from 12 to 17 years): The recommended oral dose is 15mg once daily for adolescents weighing at least 30 kg. Adults and adolescents 12 years and older: Upadacitinib can be used with or without topical corticosteroids. Topical calcineurin inhibitors may be used for sensitive areas such as the face, neck, and intertriginous and genital areas. Consideration should be given to discontinuing upadacitinib treatment in any patient who shows no evidence of therapeutic benefit after 12 weeks of treatment. Special Populations: Elderly: For AD, doses higher than 15mg once daily not recommended in patients aged 65 years and older. Limited data for patients aged 75 and older. Renal: No dose adjustment required in mild-moderate renal impairment. Upadacitinib 15mg once daily should be used with caution in patients with severe renal impairment. Upadacitinib 30 mg once daily is not recommended for patients with severe renal impairment. Upadacitinib has not been studied in subjects with end stage renal disease. Hepatic impairment: No dose adjustment is required in patients with mild (Child Pugh A) or moderate (Child Pugh B) hepatic impairment. Should not be used in patients with severe (Child Pugh C) hepatic impairment. Paediatric Population: No data available in the following paediatric patient populations: children with AD below the age of 12 years; children and adolescents with RA, PsA and AS aged 0 to less than 18 years. CONTRAINDICATIONS: Hypersensitivity to active substance or excipients. Active tuberculosis (TB) or active serious infections. Severe hepatic impairment. Pregnancy. SPECIAL WARNINGS AND PRECAUTIONS: See SmPC for full details. Immunosuppression: Combination use, with immunosuppressants e.g. azathioprine, ciclosporin, tacrolimus, and biologic DMARDs or other JAK inhibitors has not been evaluated in clinical studies and is not recommended as the risk of additive immunosuppression cannot be excluded. Serious infections: Serious and fatal infections have been reported. Caution when treating patients ≥65 years. Frequently reported – pneumonia and cellulitis. Bacterial meningitis has been reported. Opportunistic infections reported –TB, multidermatomal herpes zoster, oral/oesophageal candidiasis, and cryptococcosis. Do not initiate treatment in patients with active, serious infection, including localised infections. Consider the risk/benefit of treatment in patients with: chronic or recurrent infection, history of serious or opportunistic infection, those exposed to TB, those who have resided or travelled in areas of endemic TB or endemic mycoses, those with underlying conditions that may pre-dispose patients to infection. Closely monitor patients and interrupt treatment if there are signs and symptoms of infection pre and post treatment. Tuberculosis: Pre-screen patients for active or latent TB. RINVOQ should not be given to patients with active TB. Consider anti-TB therapy in patients with previously untreated latent TB or in patients with risk factors for TB infection. Consult with a physician with experience in TB therapy to assess whether initiating anti-TB therapy is appropriate for an individual patient. Monitor patients for the development of signs and symptoms of TB, including patients who tested negative for latent TB infection prior to initiating therapy. Viral reactivation: Cases of herpes virus reactivation have been reported e.g. herpes zoster. If herpes zoster is reactivated, consider interruption of upadacitinib therapy until the episode resolves. Screen for viral hepatitis and monitor regularly for reactivation before starting and during therapy with upadacitinib. Patients, positive for hepatitis C antibody/hepatitis C virus RNA and hepatitis B surface antigen/hepatitis B virus DNA were excluded from clinical studies. If hepatitis B virus DNA is detected while receiving RINVOQ, a liver specialist should be consulted. Vaccination: Use of live, attenuated vaccines during or immediately prior to therapy is not recommended. It is recommended that patients be brought up to date with all immunisations, including
