Managing a healthy and safe laboratory Tim Collins, British Laboratory Managers Association, UK

A

s a laboratory manager, health and safety matters will inevitably be very much at the forefront of your mind. However, it is a huge topic and it’s possible to get bogged down in the mass of detail, legislation, directives and so on, and overlook the bigger picture - why it is important and what you, as a manager, can do to promote and maintain a safe and healthy workplace. Back to basics - it isn’t just ticking the right boxes. Fundamentally, health and safety is about people like you and me. It matters because failure to take it seriously can affect anyone who might be injured or become unwell because of something that happens in the workplace. People’s attitude is probably the greatest influence on whether they will suffer injury or illhealth, so raising awareness and encouraging compliance and safe practice is worthwhile.

Legal implications There are legal implications too. The penalties of failing to comply with UK law can be severe, with prosecutions leading to hefty fines or even imprisonment. When safety is disregarded, the impact may be personal, practical or financial. Any or all of these could adversely affect how efficiently your laboratory runs. The effects may be short-term, with the absence of a colleague, or over an extended period, for example through long-term loss of confidence in your business or increased insurance premiums. The Health and Safety Executive (HSE) state that: “All workers have a right to work in places where risks to their health and safety are properly controlled.” One of the laboratory manager’s roles is to facilitate this.

Forward planning A good manager will be committed to maintaining an overview of what happens within their laboratory, to ensure that everyone works safely and does not endanger themselves (or others), and that the laboratory operates both within the obligatory legal framework and any local organisational policies and practices.

But none of this will happen without forward planning, maintaining continuous awareness of events (normal and otherwise) in your laboratory through observation and effective communication with co-workers, and assessing risks regularly, particularly when personnel, practices or protocols change. Equally important is analysing what happened when things go wrong and, of course, rectifying problems, keeping abreast of current legislation and training requirements (including your own), maintaining appropriate records, and a raft of other tasks. You could say that, for a manager, the key to a safe and healthy workplace is first-class organisation!

delegatING tasks However, this doesn’t mean that you must take on every duty yourself - indeed you could, and should, delegate specific tasks to capable colleagues, whilst retaining responsibility for ensuring these are carried out diligently and competently. Not only can this lessen the manager’s workload, but involving others empowers them to take responsibility, and to view health and safety in a more positive light and relevant to them. There’s much to consider, which can seem daunting, but you don’t have to memorise everything. In addition to information you undoubtedly already have, there is a wealth of information and resources available to guide you. The Health & Safety Executive website is a good starting point, offering industry specific and more general guidance. The UK Institution of Occupational Safety and Health (IOSH) provides excellent advice and run useful training courses, including ‘Working Safely’ and ‘Managing Safely’.

When considering Health & Safety, what might a laboratory manager need to be well-informed about? Firstly, be clear about the difference between risks and hazards: A hazard is anything with the

potential to cause harm to you or to your colleagues. A risk is the likelihood that a given hazard will cause harm or promote an adverse health effect. Broadly speaking, hazards fall into three major classes: Chemical - everything from cleaning materials, to acids, alkalis and oxidising agents, to laboratory drugs (e.g. antibiotics), solvents, and compressed gases. Chemicals may be toxic, corrosive, flammable, reactive or incompatible with other chemicals, or even explosive. Exposure to chemical hazards can occur during use or with poor handling, storage or disposal, and the potential for harm or injury can be significant if they are misused or mishandled. Biological - causing harmful effects in humans, adversely affecting health. Hazards can include bacteria, viruses, parasites, fungi, plants or animals (genetically modified or not), medical waste, or even foodstuffs, and be toxic, infectious or allergenic. As above, poor handling, etc. presents the potential for harm, but biological hazards differ from chemical as certain hazards can pass the threat from person to person. Physical - encompasses a wide range of hazards. These include electrical hazards, ergonomic problems (e.g. poor posture, manual-handling issues such as lifting/pushing/pulling objects, repetitive strain from equipment use), slips/trips/falls or falling objects hazards (associated with poor housekeeping), use/ handling/disposal of sharps, temperature extremes (hot and cold), excessive/continual noise, poor lighting, mechanical hazards (e.g. using robotic or moving equipment), vibration, working at heights (even if just using a stepstool to reach material stored on a high shelf). To these we can add the potential for fire, radiation hazards, and dangers from ultraviolet light or laser use. A further hazard class is sometimes added - psychological hazards created by work-related stress or a stressful environment. Looking at risk, the HSE states that “You are legally required to assess the risks in your workplace so that you put in place a plan to control the risks.”

You are not expected to eliminate all risk, but you are required to protect people as far as is ‘reasonably practicable’. Evaluating the risk associated with any of the hazards above forms the starting point for your assessments, and you need to consider who might be harmed, and how. Then decide upon appropriate control measures to minimise the risk. But this isn’t enough - you must document the assessment and, crucially, ensure the control measures are put in place, and used. Finally, you will need to review your assessments periodically, and update them whenever necessary. It is noteworthy that the risks involved with any laboratory work increase significantly with lone working. Managers should strongly discourage team members from working alone unless absolutely necessary. If unavoidable, procedures must be in place to accommodate this, e.g. a buddy system or regular ‘check-in’ times. However, procedures must both be followed and monitored. Regarding workplace health, we must consider how to avoid work-related illness of all types. Physical illness is important (potential biological, chemical or physical origins should be monitored and health screening carried out where necessary), but don’t overlook the importance of other workplace stressors. Mental well-being is vital, so think about work-life balance, interactions between individuals (e.g. preventing bullying/ harassment), how tasks are planned/carried out, and consult/ involve employees about how the laboratory should operate. Encouraging behaviour which promotes overall health (e.g. diet, activity, smoking-cessation) is another matter to consider. This could benefit the laboratory through reducing absence and staff-turnover, and may help increase performance, employee engagement and productivity. Finally, the laboratory manager should ensure that all staff are aware of the organisation’s policies, procedures and rules and know who to contact if they feel they need help or support.

MERT CERTIFICATION

Part 2

Understanding the data and true value of a calibration certificate Guy Snelling, InterCal

I

n part 1 of the article we looked at the requirements of the International Organization for Standardization (ISO) 17025 standard regarding calibration certificates, by studying a sample certificate to see how these requirements have been met. In part 2 we continue with a more detailed explanation of some of the more misunderstood points on a calibration certificate and our travels will end with a look at how a calibration certificate can be used to increase confidence in measurements and how it can save you money.

How is all this information useful? So we have our calibration certificate and we now have a bit more of an idea of what it all means. But what do we do with it? Well there are several reasons for having an instrument calibrated in the first place, so let’s deal with them one at a time. Traceability The measurements that you make

with your instruments are most useful if they can be related to other, similar measurements. Thus the mass of a sample measured in one country should give the same mass when measured in another country. This helps companies to maintain manufacturing tolerances throughout the world so that end users can have confidence in the products that they buy. This is easily achieved when the measuring instruments in each country have both been calibrated using standards that are traceable to each other. Calibration certificates must therefore indicate this traceability, either by listing the standards used in the calibration or by a statement to the affect that the measurements are traceable. In any case, records of standards used are kept by the calibration laboratory for inspection. Uncertainty In an ideal world, the measured mass of a sample measured in one country would be exactly the same as the measured mass

of the same sample measured in another country. Unfortunately there are many factors that can affect a measurement and therefore the two measurements will differ by a certain amount. The factors that influence the measurements are evaluated and an uncertainty of measurement is determined. Taking this uncertainty into account helps us to make decisions about the accuracy of our measurements and therefore, for example, the acceptance or rejection of a sample based on its specification. One of the factors used in determining the overall uncertainty of the measurements is the uncertainty of measurement value quoted on the calibration certificate. This should be used in your own calculations for the uncertainty of any measurements that you make with the instrument. Another value to be used is the reference made to the ‘confidence level’ that was quoted on the first page of our example certificate. This is used

Earn CPD points! in the statistical calculations of the uncertainty of measurement. As an example, let us take some values from our example certificate for an electronic balance. When a mass piece with a value of 100.0000g was applied, the balance indicated a value of 100.0000g. This looks as if the balance has no error, however the uncertainty of measurements is given as ± 0.0003g, and the confidence level is given as 95%. The English translation of these figures would read as follows: When I place exactly 100g on my balance, it will read somewhere between 99.9997g and 100.0003g, 95% of the time. Only 95% of the time? What about the other 5%, you ask. Well, if the calibration laboratory has done its calculations correctly then statistically one measurement in every 20 may fall outside of the ±0.0003g. This is why it is important to take multiple measurements if you want accurate results. Much literature has been written about the calculation of uncertainties of measurement,


MERT CERTIFICATION but one that is widely used is Assessment of uncertainties for measurement for calibration and testing Laboratories, by RR Cook, more affectionately known as The Cook Book. Reference should be made to such literature for further information about the calculations of uncertainties of measurement. Reliability When using an instrument you need to know that the readings can be trusted. Again, in an ideal world every instrument would read perfectly every time. Unfortunately the state of affairs is not so easy and readings on an instrument will vary even when measuring the same sample, and this variance will change over time. The degree of this variance should always be within the specification of the instrument since the specification is the basis on which the instrument was initially purchased, otherwise corrections must be made. The results on the calibration certificate will indicate the degree

of accuracy of the instrument, but only at the time and conditions of the calibration. The tendency of these results to drift can only be determined by historical data and this is why there is the necessity for regular calibration. Previous calibration results can be graphed against more recent ones and the drift can then be determined and extrapolated (with care) to determine the current accuracy of an instrument. Incidentally, if a system of validations is in place, whereby a few repeatable measurements are made regularly between calibrations and are monitored, then these values can be used to predict the values that the calibration laboratory will report. If the predicted values and the calibration values agree, then a high level of confidence is placed not only on the instruments but also on the validation system. This can often be used to extend calibration cycles and therefore to save money. After all, if my regular validations show that the

instrument has not drifted over a two year period, then I could make a case for extending the calibration cycle and skipping the next scheduled calibration. But, extreme care must be taken with the validations and the additional work along with the risks of inaccurate measurements caused by extending the calibration cycle may not warrant the financial savings at all. Accuracy Of course the most important question to be asked is: How accurate are my measurements? This can be determined by analyzing the results on the calibration certificate. Again, the actual results given on the certificate may vary both in specific values and also in formats, but generally the value of a standard is shown and the result obtained when using the instrument to measure that standard is given. (Obviously this applies to measuring instruments. Certificates for instruments that source a value

will give the nominal value of the instrument, along with the value measured by the standard measuring instrument). The actual error of the instrument may then have been calculated and shown or a correction value is given. (‘correction’ is the algebraic opposite of ‘error’ and by convention corrections are algebraically added to results) At some point however, it may be tiresome to correct large errors of an instrument and the instrument will need to be adjusted. It is critical to maintaining a valid history that calibration values are determined before adjustments are made, and then those same values are measured again after the adjustments. These are often listed on certificates as ‘pre-cal’ and ‘post cal’ values or sometimes ‘as found’ and ‘as left’ values. However they are named, the use of these values can allow the continued determination of the drift to be maintained.

LMS Issue 3 | 2016

MERT CERTIFICATION

Of course, if an instrument becomes faulty and requires repair and re-adjustment, then ‘pre-cal’ values cannot be determined and the historical data becomes less useful.

What about recalibration? Even though an instrument may have been supplied with a calibration certificate from the manufacturer, unless this certificate indicates its traceability, then it’s not worth very much. It is therefore important to have new equipment suitably calibrated at the time of purchase before putting them into use. This calibration will also form part of the commissioning or qualification of an instrument, and also gives useful evidence in a case for a warranty claim if an instrument is found to be out of specification. But then how often should the instrument be recalibrated? The ISO standard 17025 firmly puts this decision into the hands of the user. A typical calibration

certificate may carry a statement that a recalibration period must be chosen that will ensure that the accuracy of the instrument stays within predetermined limits, but again those limits are to be determined by the user. Generally speaking though, recalibration should be performed when you no longer have confidence in the measurements made by the instruments, or can no longer prove traceability of the measurements. Factors that may be used to determine the recalibration period, or calibration cycle, would be the amount of use, the way it is handled, and the degree of required accuracy. Regular validation measurements can be used to monitor the drift of an instrument and to then determine its current accuracy. Using statistical analysis of calibration results and also of validation measurements, expected calibration intervals can be chosen and either shortened or extended as required. It is therefore important

that records be maintained of calibration, validation and maintenance work, and it may also be useful to restrict the use of the instrument only to suitably qualified persons. As mentioned earlier, ISO17025 discourages the calibration laboratories from including a ‘recalibration date’ on a certificate. ISO does however realise that such a date may be a requirement for the customer for quality system or legal purposes, and so makes allowances for it, but only under specific instruction from the customer. It is important then to liase with the calibration laboratory about a recalibration date, and to instruct them in writing of your requirement. Most calibration laboratories have staff with many years experience with different types of instruments used under varying conditions, and their advise can usually be sought when determining calibration intervals.

Conclusions And so we come to the end

of our journey through the calibration certificate. We have seen why calibration certificates are issued, what information appears on the certificate and why, how to use the results data to show the accuracy of your instrument, how to use the certificate to maintain calibration history and to determine drift and therefore how determine calibration cycles. All of this information, if used correctly, adds value to your instrument - not only in the value obtained from being able to trust measurements taken by the instrument, but also an increase in the value of the instrument itself. Should you choose to sell the instrument at some point, the inclusion of a comprehensive calibration history file into the sale may actually increase the sell price past the initial purchase price. So the next time you balk at the prospect of spending money on calibration, rather think of it in terms of investment rather than expense.

LEARNING ABOUT SHARK LIFESTYLES

T

he KwaZulu-Natal Sharks Board (KZNSB), situated north of Durban, has been using a Telstar freeze dryer supplied by Labotec to preserve biological samples used for local and collaborative research. Their work focuses on stable isotopes, which are delivering interesting information on the presently little known food web interactions over ontogeny, the presence of retroviral DNA, and in the future, they will be looking at projects such as the shark species’ sensitivity to mercury toxicity. Debbie Shaw from Labotec spoke to Nomfundo Nkabi, Junior Scientist at the research centre, about the exciting work happening now, as well as future planned studies involving the preserved biological samples.

Q

Tell us more about the laboratory aims and objectives at the Sharks Board where the Telstar unit is situated?

A

The Telstar freeze dryer at the KZNSB is stationed in the wet laboratory where all sharks caught in shark safety gears are measured, sampled (e.g. taking various tissue samples for a number of research projects) and kept frozen for public dissection. The KZNSB is running a long-term monitoring collaborative stable isotope project. In the past years, it preserved more than 2 000 tissue samples using an off-site freeze dryer. It is advantageous to have the machine in-house for us to meet project time frames. We use it for preserving various biological samples requested by local and international researcher as part of collaborative research projects.

Q A

Please tell us more about the research happening in the laboratory. Samples of shark muscle, liver and skin have been freeze-dried for stable

isotope analyses. Sharks are large predators, considered to feed at the top level of marine food webs. Although much is known regarding their feeding behaviour in coastal regions, little is known regarding their diet and food web interactions over ontogeny (developmental history within its own lifetime). In addition, limited work to date has investigated intra-population level variation in the diet and trophic position of the white shark. The stable isotopes of carbon and nitrogen provide tools to track both baseline productivity and relative trophic positions of individual animals, respectively, and can also be used to provide information on niche width. Samples of muscle were also freeze-dried for analyses of shark retroviruses. The literature suggests that sharks are remarkably resistant to viral infections, in part because there has been little noticeable pathology observed during studies of various shark species.

However, there have been no molecular screens to detect viruses that are not causing visible disease. The KZNSB is involved in this research by making the samples available, which enables UK researchers to identify whether retroviral DNA, from either endogenous or replicating retroviruses is present in a variety of different shark species.

Q A

What interesting future projects are on the cards?

The Telstar freeze dryer will be used by two interns from early next year for various internal stable isotope projects. We will also be using it for a toxicology study, which will focus on determining the mechanisms and consequences of mercury demethylation in fish. The samples preserved will be used, to make predictions about species sensitivity to mercury toxicity.

All sharks caught in shark safety gears (for the protection of public swimmers on the SA coastline) by the KwaZulu-Natal Sharks Board are measured, sampled, and the preserved biological samples are used for local and collaborative research. This research is delivering interesting information on the presently little known food web interactions over ontogeny as one example of their work. To facilitate project time frames for analyses, Labotec recently supplied a Telstar freezer for on-site freeze-drying of shark muscle, liver and skin.

Lab in a needle

A

team of engineers from the US and Singapore have developed a lab in a needle device that could provide instant results to routine lab tests, accelerating treatment and diagnosis by days. This single, self-contained medical device will be effective, for example, in quickly detecting liver toxicity, which is a common side effect of chemotherapy. This device will test toxicity in 30 minutes while current liver toxicity tests take several days due to multiple steps required before a physician interprets the test results and communicates them to the patient. Developed jointly by Houston Methodist Research Institute, Nanyang Technological University (NTU Singapore) and the Singapore Institute of Manufacturing Technology (SIMTech), a research institute of the Agency for Science, Technology and Research (A*STAR), the invention was explained in the recent issue of the Royal Society of Chemistry’s Lab on a Chip.

Approach The investigators demonstrated that two important steps of the lab in a needle approach accurately detected liver toxicity in pre-clinical models by measuring two genetic indicators of toxicity in aspartate transaminase and alanine transaminase. The proteins represented by these indicators are among the most sensitive and widely used

liver enzymes in all liver function tests today. “We used the concept of lab on a chip, which compresses the entire function of a laboratory diagnostic test onto a tiny microfluidics chip, to create lab in a needle,” explained Dr Stephen Wong, Chair of the Department of Systems Medicine and Bioengineering at Houston Methodist Research Institute. “Our goal is to integrate sample acquisition and preparation into one device, a significant challenge that has slowed the development of point-of-care testing.”

Diagnostic testing The joint research group sought to develop a new class of device to collect patient samples, prepare them for testing, evaluate toxicity, and display results in one easyto-use process, allowing doctors and patients to immediately discuss treatment options. A compact device would also make possible diagnostic testing outside of a clinical setting, such as at home or in the field. “What we have proven is when the doctor takes a blood or liver sample, the sample can be prepared and analysed using lab on a chip methods which eliminates the need for wet laboratory work and experts,” said Joseph Chang, a professor of circuits and systems and biomedical engineering expert and Director of Virtus, based at the NTU’s School of Electrical and Electronic Engineering. Sample preparation was

accomplished on one chip that incorporated a miniature motor and microfluidics, while amplification was performed on a second connected chip, said Prof Wong. Elevations in the two examined gene markers of liver toxicity were then accurately detected and consistent with previously known changes, indicating that lab in a needle is an appropriate diagnostic option. “Our next steps are to integrate the sample preparation and analysis chips into a miniaturised device. A*STAR SIMTech will tap on its manufacturing process capabilities to develop a cost effective lab in needle device that can be scaled up for mass production. This will enable the mobile technology to be expanded to test for a number of health conditions in outpatient settings or outside hospitals,” said Dr Zhiping Wang, a principal scientist in microfluidics and Director of Research Programmes at A*STAR SIMTech.

Study outcome The study outcome represents the first time that all processes involved in the lab in a needle were integrated together successfully, and represents an important step in bringing a new real-time, easy-to-use diagnostic to the clinic and the field with immediate potential to improve patient outcomes and quality of life.

High-throughput screening strategy identifies antibiotic-resistant bacteria

Beyond LIMS

I

nterSystems, a global leader in software for connected care and developer of the InterSystems TrakCare® unified healthcare information system, recently announced that it will release its next-generation laboratory business management system (LBMS) soon. “The nature of the laboratory business is changing dramatically,” said Martin Wilkinson, Head of InterSystems’ solutions for the laboratory market. “While the pressure to deliver more test results at lower cost will only intensify, advanced information technology will enable laboratory professionals to be the drivers of change, not the victims.” Market trends like healthcare industry consolidation are disrupting the laboratory business. Advances in automation, genomic testing, and the increased use of point-of-care testing will drive further shifts in where and when testing takes place. Nextgeneration systems will capture information at each stage of the healthcare continuum to enable unprecedented flexibility and clinical validity.

Business Management Systems “Labs will inevitably need to move from a support service to a business that helps drive better healthcare outcomes. “The next generation of informatics solutions are designed to manage the lab as an agile, knowledge-driven business in an increasingly interconnected

world. Today’s laboratory information management systems fall short of what labs need. We are raising the bar by introducing the world’s first LBMS, which will help customers transform from a reactive testing and results service to a proactive healthcare partner,” said Wilkinson. An LBMS will enable laboratories to work differently. Not only will they communicate lab results electronically, but they will also identify their derivation, including workflows, equipment, and personnel involved, regardless of where they are located. Connected care models and shared electronic health records will also see laboratory professionals become more directly involved in patient care. With a continuous view of the patient’s condition, lab professionals will extend

their services into hospital wards and other settings. An LBMS will provide the following new capabilities: Distributed sample processing: Samples may be collected in one location, processed at another, analysed at a third, and digitally referred to yet another location for a second opinion. Accountability and process improvement: Complete visibility and control over the testing process - including which tests are running at a profit and which ones at a loss - will enable greater accountability and allow laboratories to continually improve processes and optimise distributed workflows and resources. Efficiency through automation: Standard operating procedures with full auditability

will not only support distribution of workflows across multiple sites, but also drive further automation by decreasing the percentage of tests requiring manual intervention. Patient-centric care: Support for connected care models will put patients at the centre of the testing process with a contiguous pathology patient record, integrated within the electronic health record, including all test data - including point-of-care test results. Quality assurance: Lab professionals will extend quality assurance outside of the laboratory using asset management functionality for equipment data, with maintenance events viewed and analysed alongside patient test results.

Internationally recognised standard of practice

I

n light of the importance of laboratory output and the potential of harm of incorrect laboratory results, many worldwide opinion leaders in the laboratory profession felt there was a need for an internationally recognised standard of practice for medical labs. This need was driven by the desire to elevate laboratory quality and make efficiency a priority for all laboratories. Another important

factor was a need to harmonize laboratory performance. With the increasing mobility of the world’s population, it has become necessary and important to assure that test results reported in one location could be replicated, in terms of medical actions taken, at another location particularly for patients with medical conditions that require on-going monitoring.

Peering into tissue stiffness

R

esearchers at the University of Maryland have developed a novel spectroscopy configuration that can obtain a sample’s entire Brillouin spectrum in one shot - saving time and allowing for noninvasive biological characterisation. At a microscopic level, every material contains spontaneous sound waves - acoustic phonons that have properties dependent on the material’s mechanical properties. When light interacts with these acoustic phonons, it scatters and acquires a frequency shift related to the material’s elastic modulus, a characteristic measure of its ability to resist deformation and stress.

Brillouin spectroscopy A technique known as Brillouin spectroscopy works by measuring this frequency shift, and has been an effective tool for noninvasively examining materials for several decades. The technique, however, necessitates scanning interferometers, which are lowthroughput and result in long data acquisition times. To bring this method to biological samples - such as a chicken breast, or a patient’s potentially cancerous tumour - researchers at the University of Maryland and Harvard Medical School have recently developed a new virtually imaged

phased array-based Brillouin spectrometer. They recently describe their new interferometer configuration in Applied Physics Letters. “We have been developing this new VIPA-based Brillouin spectrometer for a long time. In this paper, we added a multi-pass low-finesse Fabry-Perot interferometer, which works as a tunable and narrowband filter,” said Giuliano Scarcelli, an assistant professor in the Fischell Department of Bioengineering at the University of Maryland.

Saving time and power While past development of virtually imaged phased arraybased spectrometers allowed the researchers to collect the entire Brillouin spectrum in a single shot, saving processing time and power, the design could only interrogate transparent materials such as ocular tissue or cells because turbid media generate too much unwanted light noise for the spectrometer to handle. By adding a triple-pass FabryPerot filter, the researchers were able to increase the spectrometer’s ability to suppress such unwanted light component by more than tenfold, allowing them to measure background-free spectra up to 100 micrometers deep within a

sample of chicken tissue. Future work for Scarcelli and his colleagues includes improving Brillouin technology to measure spectra faster, with greater sensitivity and at higher spatial

resolution, as well as expanding characterisation to include tumours, atherosclerotic plaques and brain tissue. Source: American Institute of Physics

Influenza season starts late

A

ccording to the National Health Laboratory Service the 2016 influenza season is due to start later this year. In the past, influenza season started during the last week of April. During the first nine weeks of 2016, three patients were diagnosed with influenza A (H1N1) pdm09 and influenza B. During the same period, specimens from 171 patients were received from two influenza-like illness surveillance sites. Influenza A (H3N2) was detected in one specimen from an adult patient and influenza B from a four-year-old. Both these patients had no travel history or known contact with people who had travelled to areas where influenza is currently circulating. Between 01 January and 03 March, specimens from 520 patients with severe respiratory illness admitted at the six

pneumonia surveillance sentinel sites were tested for influenza. Influenza B was detected in the specimens of four patients. In 2015, the flu season started in week 16 (ending 19 April), peaked in week 23 (ending 7 June) and ended in week 37 (ending

13 September). In past years the season has started as late as the first week of July.

Influenza subtype Data from 2015 indicated that the predominant circulating influenza subtype was influenza A (H1N1) pdm09, followed by influenza A (H3N2). The vaccine for the southern

hemisphere will contain an A/California/7/2009 (H1N1) pdm09-like virus, A/Hong Kong/4801/2014 (H3N2)-like virus and B Brisbane/60/2008-like virus.

Strains The following strains have been recommended by the World Health Organization for the trivalent IIV 2016 southern hemisphere influenza season:  A A/California/7/2009 (H1N1) pdm09-like virus.  A A/Hong Kong/4801/2014 (H3N2)-like virus.  A B Brisbane/60/2008-like virus. These recommendations include a change in the A (H3N2) and B strains when compared with the composition of the trivalent IIV used for the southern hemisphere during the 2015 season.

ACQUITY Arc system awarded best New Separations Product of 2015!

T

he Acquity ® Arc™ system from Waters won the Scientists’ Choice award for Best New Separations Product of 2015 during a SelectScience ceremony at the recent Pittcon Conference and Exhibition in Atlanta (US). The Waters Acquity Arc system, is a quaternary liquid chromatograph that gives analytical laboratories running established liquid chromatography (LC) methods a clear choice for replicating or improving their separations performance. The Acquity Arc system is specifically engineered to respond to the needs of analytical scientists for a single LC platform that can enable them to efficiently transfer, adjust or improve their methods regardless of the LC platform on which they were developed. Scientists working with established methods have not

had an LC platform versatile enough to bridge the gap between high performance liquid chromatography (HPLC) and ultra-performance Liquid Chromatography (UHPLC)®. With the introduction of the Acquity Arc system, and its enabling Arc Multi-flow path™ technology, scientists now have the ability to emulate the

gradient dwell volume and mixing behaviour of various LC systems. By selecting the appropriate fluidic path, the Acquity Arc system can easily emulate a variety of HPLC systems without altering the method’s gradient table, or provide UHPLC performance with the flip of a switch. In addition to replicating

established HPLC assays without altering the gradient table, the Acquity Arc system can enable improved chromatographic performance of methods by leveraging 2.5-2.7 micron particle column technologies, as well as support previously developed applications on 3-5 micron HPLC columns. Waters is offering a full complement of LC detectors for the Acquity Arc system, including photodiode array, UV/Vis, fluorescence, refractive index and evaporative light scattering. The system is also fully compatible with the Acquity QDa® mass detector. In addition, the Acquity Arc system features novel Auto-Blend Plus™ technology that enables the operator to program directly % organic and % pH gradients to significantly reduce human error and the manual labour associated with preparing buffered mobile phases. The Acquity Arc system is controlled through Waters industry-leading informatics packages of Empower ® 2 or Empower 3 software.

Does your sodium determination method comply with the South African law?

T

he salt content of food products influences the taste, but can also adversely affect health. There is a clear link between sodium intake and high blood pressure. The World Health Organization has published data showing that blood pressure is the number one health risk factor in Africa. Hence, food producers are forced to declare or even reduce the standard amount of salt (sodium chloride) content in foods. In SA, reduced sodium levels should be met and adhered to, as governed by law and regulations for their respective products.

As approved by the Minister of Health, Dr. A. Motsoaledi, Gazette No. 32674: Regulations Relating to the Reduction of Sodium in Certain Foodstuffs and Related Matters states: “…the following methodology for determining typical total sodium content shall apply for monitoring purposes…” “For all foodstuff categories, except bread, suitable potentiometric method or elemental analysis with flame atomic absorption spectroscopy or inductively coupled plasma.” It should be noted that, unlike thermometric methods available, Mettler Toledo’s

unique potentiometric titration methods fully comply with the South African law as set out in the Gazette under the selection of analysis options on applicable foodstuffs, and serves as a cost effective solution (both initial and operational) to the alternative allowable technologies. Current methods of measuring salt content often determine only chloride levels, which can lead to inaccurate sodium measurements due to the presence of other chloride compounds, such as potassium chloride (KCl) in addition to sodium chloride (NaCl), likely to result in an over statement of sodium content.

Similarly, alternative sodium sources may also be present that may result in an under report of sodium content. By directly measuring the harmful sodium concentrations rather than chloride levels, Mettler Toledo’s new Excellence T-series titrators and dedicated EasyPlus™ sodium analyser provides simple, fast and accurate results in food laboratories and manufacturing processes. The EasyPlus sodium analyser eliminates the need for expensive complex instruments. It uses an integrated and dedicated sodium evaluation algorithm to deliver highly accurate and repeatable results that are comparable to those achieved using more complex analytical techniques for total sodium analysis. The sodium ions are measured directly without the need for calibration. Simplified sample preparation further reduces operator time and the required standards and reagents are cheaper, safer and available as ready-to-use solutions. Similarly, the new Excellence titration T-series now includes the above features. InMotion sample changers and dosing units may be added on to achieve full automation of the method. LabX software allows connectivity for data management and direct determination of a variety of other ions. Thus, sodium, potassium and chloride parameters can be determined, using a single instrument without compromise. Source: Microsep (Pty) Ltd

Preventing an environmental disaster

O

ptical emission spectrometers can contribute decisively to prevent accidents. Bruker Elemental’s Q4 MOBILE provides the petrochemical and metals industries with a compact metal analyser, capable of analysing the critical carbon content in used steel. The smallest concentrations of carbon in the ppm range impact the steel’s durability, strength and weldability. In April 2010, seven employees were killed in an explosion caused by a high-temperature hydrogen attack in a refinery in the US state of Washington. Since the accident was caused by metal fatigue, mobile OES instruments were needed. Since then, relevant equipment, especially process piping systems have to be tested in accordance with the ‘Material Verification Program’ (guidelines API 578) of the American Petroleum Institute. Components that do not meet the required specifications are identified and replaced. For this task Bruker Elemental´s Q4 MOBILE is the optimal control and measurement analyser. With the last two years very successfully on the market, the Q4 MOBILE performs rapid metal analysis, identification and sorting. The highlight is its mobility. With an optional four-wheeled trolley, the spark spectrometer and accessories easily roll to the place where analysis is needed. Controlled by an intelligent energy management system, Q4 MOBILE can use any standard power source, even a cigarette lighter in a car. Adaptive Ambient Control (AAC), which adjusts the optics automatically to the ambient temperature, ensures a short preparation time. Long setup times are a thing of the past. Work is carried out with the help of a handy probe, which allows ergonomic handling thanks to the lightweight, flexible hybrid cable, even during prolonged activity. Depending on the requirement, whether in spark or arc excitation, the quick change adapter allows switching the analysis mode in seconds. For shorter wavelengths such as UV, a rapidly modifiable probe with high resolution optics is available. Thus even the most demanding applications, such

as C, S or N determination, are possible. This underlines strongly the outstanding Bruker analytics of the Q4 MOBILE spectrometer. “For 316 and 316L stainless steel alloys, the difference in the carbon concentration is indeed minimal, but this difference is of decisive influence on the respective corrosion behaviour,” said Bruker Product Manager, Hans Dominick. “Our Q4 MOBILE analyses carbon contents in the corresponding ppm range

and can thus clearly determine the respective alloy. The use of components with incorrect element composition is prevented and expensive failures or dangerous accidents avoided.” Via a display on the probe, the analysed alloy designation is directly shown. Nothing could be faster. High capability, practical relevance, ease of use and functional mobility - these are the strengths of the Q4 MOBILE. Thus Bruker fulfils all customer requirements.

“Not only the petrochemical industry appreciates the Q4 MOBILE in the implementation of current guidelines for material control and material testing on oil rigs or pipelines. The Positive Material Identification in incoming goods inspection or metal sorting is another important use for material traders, in which rapid analysis brings clarity and ensures functional processes. Downtime costs a lot of money, and this can be avoided with Q4 MOBILE..

First successful extraction of ancient DNA

R

esearchers have presented one of the first computerised tomography (CT) scans of a mummified individual from southern Africa, and also completed the first successful aDNA (ancient DNA) extraction from such remains. The mummy is estimated to be about 300 years old.

Prof Maryna Steyn, Head of the School of Anatomical Sciences at the University of the Witwatersrand, together with researchers from the University of Zurich (Switzerland), University of Pretoria and University of Botswana have published these findings in a paper published in the South African Journal of Science.

Mummified human remains are valuable sources of information on past populations. The researchers reported on the radiological and molecular findings of a partially mummified individual found in northern Botswana, in the Tuli block. The researchers noted that this desiccated mummy from the Tuli

The intact mummy, covered with animal skin, discovered in the Tuli region of Botswana.

Food allergies better understood

S

cientists have taken a step closer to explaining food allergies, especially those in children. The new research shows how food antigens stimulate immune cells in the gut that prevent the immune system rejecting food. “The immune system evolved to protect us from things that are not ourselves, like viruses or pathogens, yet we consume nutrients, which are themselves foreign. “Our work shows food tolerance is acquired and involves specific populations of T cells that develop following its consumption. Without them, we would mount a strong immune response to macromolecules contained in food,” said Dr Charles Surh of the La Jolla Institute in California (US). Scientists used antigen-free mice raised in a germ-free environment and only fed amino acids were depleted of T-regulatory (Tregs) cells.

However their counterparts who were fed a ‘normal’ protein diet had a large number of these cells. Tregs cells control the immune system, and prevent autoimmune disease. This study is the first to demonstrate the effect a normal diet has on gut cells that suppress rejection of food by the immune system. Researchers believe this can explain why children are more

susceptible to food allergies as they have more limited exposure to novel foodstuffs. As well as demonstrating this, researchers looked into what happens when immune cells ignore harmless antigens. Antigen-free mice were exposed to ovalbumin (a protein) and a massive immune reaction was observed. The researchers proposed this occurred as the antigen-free mice did not have a population of immunosuppressive Tregs that would usually reduce the inflammatory response to food. “We are now examining the cellular and molecular details of how the ‘default’ strong T cell response to food is regulated, in this context, we plan to pay particular attention to certain foods, such as peanut, egg and other foods that cause food allergy,” said Surh.

region is the first to have been reported from this region. The remains were those of an older male adult of African origin. He was interred in a tightly flexed position and wrapped in an animal skin (and tied together with rope). CT scanning revealed that none of the internal organs were preserved. Multiple post-mortem alterations are seen, but apart from some degenerative changes of the lower vertebral column, the axial skeleton has remained intact. The advanced osteophytosis (degenerative changes of the spine) suggests an older age than what was previously estimated. The cause of death could not be confirmed, but he did not shown any signs of injury. The aDNA analysis confirms that the individual possibly had a Sotho-Tswana or Khoesan genetic relatedness, as could be expected from individuals from that region.

Traditional skin tests ineffective

S

kin tests traditionally used to predict allergies to amoxicillin, one of the most commonly prescribed antibiotics in children, are ineffective, according to a new study led by a team at the Research Institute of the McGill University Health Centre (RI-MUHC) in Montreal (Canada). “Our study suggests that skin tests are essentially useless as diagnostic tests,” said lead author Dr Moshe Ben-Shoshan, an allergist at the Montreal Children’s Hospital. The results are a game changer in the way physicians assess amoxicillin allergy in children given the fact that skin tests are still the recommended screening method in hospitals, he added. “Our study is the first to determine the percentage of immediate and non-immediate amoxicillin allergy in all children presenting with a suspected amoxicillin induced rash through a graded provocative challenge,” said Dr Ben-Shoshan.

In February this year, the first case was reported in SA. According to the WHO, 64 countries and territories have reported transmission of Zika virus since 1 January 2007.

Zoonotic pathogen Zika virus is a zoonotic pathogen, naturally and experimentally hosted in non-human primates as well as experimentally in Swiss albino mice. Rhesus monkeys can be the source in natural habitats of human infections, through the bite of Aedes aegypti and A. albopictus (multiple other species and genus have been implicated), in infected monkeys and later transmission to susceptible human hosts.

Vector-borne disease Zika virus is predominantly a vector-borne disease, although after the epidemics in the Pacific region it was clear that transplacental and perinatal transmission could also occur. However, the associated risk of microcephaly has been identified and highlighted much more recently as evidences continue to be added in different studies. Before the current epidemics not a single study raised that relationship, and, right now a significant number of pregnant women and their newborns are being monitored in Brazil, Colombia and other countries in the region for central nervous system anomalies. Zika has been detected in newborns, placenta and umbilical cords, as well in pregnant women by reverse transcription polymerase chain reaction RT-PCR. There have been no reports detecting viable and potentially infective virus in

breast milk up to now.

Mother-to-child transmission In addition to mother-to-child transmission, during the last decade, cases of sexual transmission have been reported, representing a nonvector borne form of transmission of Zika virus. Zika virus has been detected in human saliva, blood, semen and urine. It has been recently detected in semen and urine of, respectively, a patient after 62 days of infection and another patient after 14 days of infection. The spread of the virus through blood transfusion and organ transplantation have been reported or suspected. Zika virus infections have been documented through laboratory exposure. Another emerging aspect of this zoonosis has been the possible transmission through bites of monkeys and other non-human primates. This has also been recently reported.

Conclusion Zika virus is primarily a vectorborne disease (mainly by A. aegypti), but there are also secondary modes of transmission (mother-to-child, sexual, blood transfusion, transplantation, nonhuman primate bites). This imply that prevention and control should consider all these ways of transmission, providing strategies to reduce new infections from this arbovirus that still need further basic, epidemiological and clinical assessment in order to clarify and understand its real impact on human health. Zika represents a real challenge for the medical and scientific community.

Mimicking evolution

roteins are nature’s machines. They provide oxygen to power our muscles, catalyse reactions that help us extract energy from food, and fend off infections from bacteria and viruses. For decades, scientists have searched for ways to design new proteins that can serve specific purposes in medicine, research, and industry. Now, researchers at the University of North Carolina School of Medicine have

developed a method that creates novel proteins by stitching together pieces of already existing proteins. The technique, called SEWING, is inspired by natural evolutionary mechanisms that also recombine portions of known proteins to produce new structures and functions. This approach can generate a diverse set of protein structures with many of the distinctive features that proteins require to carry out specific

biological functions. The findings, published recently in the journal Science, could enable researchers to design proteins to play a variety of different roles in human biology and disease, such roles as catalysts, biosensors, and therapeutics. “We can now begin to think about engineering proteins to do things that nothing else is capable of doing,” said senior study author, Prof Brian Kuhlman of the

UNC Lineberger Comprehensive Cancer Center. “The structure of a protein determines its function, so if we are going to learn how to design new functions, we have to learn how to design new structures. Our study is a critical step in that direction and provides tools for creating proteins that haven’t been seen before in nature.” Source: University of North Carolina Health Care.

Transforming water and carbon dioxide into energy

F

or years, scientists have been trying to emulate photosynthesis, the process by which plants, algae, and some bacteria harness light from the sun to chemically transform water and carbon dioxide into energy that is stored for later use. An artificial version of photosynthesis could provide a clean, renewable source of energy to help satisfy society’s growing demands. For artificial photosynthesis to become a viable alternative to fossil fuels, the efficiency and speed of water oxidation - the reaction that turns water into oxygen gas, hydrogen ions, and electrons - is one of the processes that must be improved. Now, a team of scientists from the US Department of Energy’s Brookhaven National Laboratory, Adam Mickiewicz University, and Baruch College, City University of New York, has synthesised two new molecular catalysts for water oxidation. The catalysts - complexes of ruthenium surrounded by binding molecules (ligands) containing phosphonate groups - accelerate the formation of the oxygen-oxygen bond, usually the most energyintensive and slowest step of water oxidation. Initial studies, described in a paper published on May 11 in Angewandte Chemie International Edition, demonstrated that these ruthenium complexes could offer a low-energy pathway to faster water oxidation.

Storing solar energy “Storing solar energy as hydrogen fuel or carbon-based fuels like methanol requires catalysts that can oxidise water at fast rates, with high efficiency, and

for long periods of time,” said Javier Concepcion, an author of the paper and a chemist in the artificial photosynthesis group at Brookhaven Lab. “Our ruthenium complexes catalyse the oxygen-oxygen bond formation faster than any other known catalysts, generating hundreds of oxygen molecules per molecule of catalyst per second. With these catalysts, the electrical potential required to start the reaction is approximately 10 times less than that of a AA battery.”

Forming the oxygenoxygen bond In water oxidation, four protons and four electrons - required in a subsequent reaction to convert carbon dioxide into usable energy - are removed from two water molecules, and an oxygenoxygen bond is formed. For water oxidation to occur, the bonds between hydrogen and oxygen atoms in the two water molecules must be broken. In the case of artificial photosynthesis, a chemical catalyst triggers this molecular breakup. “Water is a very stable molecule, so getting two water molecules to react with each other is very difficult,” explained first author Yan Xie, a doctoral candidate at Stony Brook University and a research assistant in Brookhaven’s artificial photosynthesis group. “Our ruthenium complexes provide the reactivity needed to break those bonds.” The paper describes details of the series of steps through which the catalyst initiates and completes the reaction. In short, one of the water molecules binds to the ruthenium complex and loses protons as the complex is oxidized (loses electrons), resulting in an

electron-deficient ruthenium-oxo group. Then, with the assistance of a phosphonate group, the other water molecule reacts with this highly reactive ruthenium-oxo to release molecular oxygen (O2). “The phosphonate group accepts protons, or hydrogen ions, from water,” said coauthor David Shaffer, a research associate in Brookhaven’s Chemistry Department. “It is positioned near the active site of the ruthenium complex where water oxidation occurs. Incorporating the phosphonate group and ruthenium in a single complex makes it easy for the water molecule to find that one site and react.” Eventually, the protons are transferred from the phosphonate group to the surrounding solution.

Studying the electrochemistry of the ruthenium complexes To determine the efficiency and rate of water oxidation with the ruthenium catalysts, the team studied the electrochemistry of each oxidation state by applying different voltages and measuring the amount of current flowing through the system at various pH values (the concentration of protons in the solution). “The voltage at which catalysis starts tells you about the energy efficiency of water oxidation, while the current tells you how quickly water oxidation is occurring,” explained Concepcion. “Our ruthenium complexes minimise the amount of energy lost as heat, both in terms of the voltage and the rate that would be required for the catalyst, if incorporated into a device, to make use of all incoming sunlight.” The team also used computational modeling to study

the activation parameters - the energy and molecular order required to break and make bonds during the key reaction between the water molecule and the ruthenium-oxo group. The computational studies showed why the phosphonate group resulted in faster catalysis. “Phosphonate is a good proton acceptor, so it energetically favors the reaction. Because it is part of the ligand, it is already positioned and ready to interact with water, removing the need for a more ordered arrangement of molecules,” said Concepcion. From separate studies, the scientists were able to tell that one of the oxidation steps not the oxygen-oxygen bond formation step - was limiting the rate of the catalysis. The team is now developing secondgeneration catalysts to optimise this step. Eventually, they hope to make equally reactive catalysts using metals such as iron and cobalt that are more abundant and less expensive than ruthenium, but whose chemistries are much more complicated. “By incorporating these catalysts into systems capable of absorbing sunlight and combining them with catalysts that reduce carbon dioxide or water into fuels, artificial photosynthesis could become a practical approach for storing solar energy as fuels,” said Concepcion.

SA ranks low on global innovation list

S

outh Africa ranks 55th in how its domestic policies support worldwide life sciences innovation, according to an analysis released recently by the Information Technology and Innovation Foundation (ITIF), a global technology policy think tank. The report assessed 56 countries, which together comprise close to 90% of the world’s economy, on the extent to which their scientific research, drug pricing, and intellectual property policies contribute to global biopharmaceutical innovation. “Life sciences innovation requires years of painstaking and expensive research. To ensure global health outcomes continue improving, more nations must do their share to support biopharmaceutical innovation and not free ride off the hard work and investment of the leaders, said coauthor Stephen Ezell, ITIF Vice-President for

Global Innovation Policy.

Innovation Building on previous ITIF research that studied the impact of national policies on the global innovation ecosystem, this report shines a light specifically on biopharmaceutical innovation. Ezell and coauthor John Wu examined three policy areas that not only support life-sciences innovation domestically but also have positive spillover effects globally: Governments’ research and development expenditures on health, the extent of price controls on biopharmaceutical drugs and intellectual property protections for life-science innovations. The analysis found that the US, Switzerland, Taiwan, Singapore, and Sweden have enacted policies that, on a per-gross domestic product basis, contribute the most to

global life-sciences innovation, while India, SA, Thailand, the Philippines, and Australia have policies that contribute the least. “Despite tremendous progress over the past half century, the world is still not producing as much life-sciences innovation as is needed or possible,” said Ezell. “Countries that fail to invest adequately in life-sciences research, pay less than their fair share for drugs, or put in place weak intellectual property protections for drugs hurt the entire global community by slowing down biopharmaceutical innovation that could cure or better manage diseases for future generations.”

Ecosystem The report also found that countries with the strongest life-sciences policies also have some of the most competitive innovation ecosystems, meaning

that doing well domestically can also mean doing well for the world. “It is on the one hand understandable that policymakers tend to focus first and foremost on the short-term interests of their own citizens, but too many ignore the fact that this comes at the expense of less innovation of new drugs,” said Robert Atkinson, ITIF president. “The bottom line is that all nations need to do their part to support robust global biopharma innovation.”

How four-stranded DNA is formed and unfolded

R

esearchers at Umeå University in Sweden have discovered that specific DNA sequences that are rich in the DNA building block guanine in the yeast species, Schizosaccharomyces pombe, can form four-stranded DNA. The researchers also show that the motor protein Pfh1 can unfold these DNA structures and thus contribute to maintaining an intact genome. DNA molecules are known for their spiral shape, with two strands wrapping around each other. But DNA can also appear in

other configurations. One of these forms consists of a guanine-rich four-stranded DNA, a so-called G4 structure. Guanine is one of DNA’s four building blocks. A number of earlier studies of different organisms have indicated that G4 structures are formed in the genome and fulfil important biological functions such as controlling gene expression. G4 structures can present a threat if they exist continuously in the genome. Helicases are a type of specialised motor protein with the ability to unfold different kinds of DNA.

Until now, there were very few studies about G4 structures in Schizosaccharomyces pombe, also known as fission yeast. It was also not known which protein is responsible for the unfolding of the G4 structures. Research on G4 structures is at its early stage. But researchers believe that G4 structures can inhibit certain processes in the cells, including DNA replication, and have tied them to the development of cancer and neurodegenerative diseases in humans.
