2 Precision Medicine Briefing, January 2021
Executive summary The ultimate goal of Precision Medicine, also referred to as Personalized Medicine, is to enable the use of information about a patient’s genes and environment. Physicians and scientists can utilize this data to more accurately identify or predict disease, delay or prevent the onset of disease, and develop more effective treatment. This could be aided by sciences like genomics, developing technology to better parse massive data sets, and by improving our understanding of the relationship between differences in DNA and basic biological mechanisms. Precision Medicine faces challenges, however, related to the healthcare workforce, costs, equal access to care, and data privacy. This briefing is based on the views of a wide range of experts from the World Economic Forum’s Expert Network and is curated in partnership with David H. Perlmutter, MD, executive vice chancellor for medical affairs and dean of Washington University School of Medicine.

Avoiding Disparities Genomic research must be more inclusive in order for the promise of Precision Medicine to be realized Important health discoveries have been made using genomic technologies such as those used to sequence and analyse DNA. However, it is necessary to capture genomic information (related to all of the genetic code within a cell) from a wide range of people in order to avoid increasing health disparities. Early genomic research focused primarily on populations with European ancestry; in 2009, 96% of the people accounted for in genome-wide association studies (or GWAS) were of European descent. By 2016, diversity in GWAS studies had improved - 19% were of non-European ancestry, with most of the growth among those of Asian ancestry. GWAS studies have shown that different genes among different ethnic groups may be implicated in both genetic and communicable diseases. In the National Heart, Lung, and Blood Instituteâ€™s Trans-Omics for Precision Medicine (TOPMed) program, which began in 2014, African American genomes make up 26% of the total analysed, while Hispanic/Latino genomes make up just 10% - nonEuropean genomes clearly remain underrepresented. Unless genomic research becomes more inclusive, minority populations will not realize the promise of Precision Medicine, and health disparities will only continue to grow. Genomic architecture can vary widely across populations, and rare variants - important for determining disease risk and drug response - tend to be population-specific. However, incorporating diverse populations in genomic research presents methodological and analytical challenges. The research community must therefore develop and incorporate new research designs and analytic tools necessary to overcome these challenges. The inclusion of diverse populations in the design of a research study must also be rewarded. Advances in genomics research should help to ameliorate, rather than contribute to health disparities among diverse populations. In addition, it is possible that the inclusion of diverse populations will bring the benefit of identifying important genes and pathways for a variety of diseases, and improve overall human health.

This brain protein may be key to treating Parkinson's â€“ study in rats shows 03 December 2020 Parkinsonâ€™s disease, a brain disorder that affects over 10 million people worldwide, is caused by the gradual loss of dopamine neurons. The loss of these neurons leads to involuntary tremors, stiffness and balance problems. While there are drugs to treat these symptoms, no drugs exist to slow the progression of the disease. However, we found a brain protein that may be able to prevent the loss of dopamine neurons. This discovery could be important for developing treatments.
5 Precision Medicine Briefing, January 2021
Ethics and Legality Protecting privacy must be a part of enabling advances in healthcare A serious downside to a fully-realized future for Precision Medicine (or "Personalized Medicine") is the fact that the genomic and other biological data included in personal medical records will be subject to potential misuse by bad actors with financial or other incentives. Without strong, enduring privacy laws, people with a certain genotype (or genetic makeup) may find themselves uninsurable, unemployable, or otherwise discriminated against. Genomic data can also accurately identify parentage, which could lead to invasions of privacy in cases such as adoption proceedings. Ethical and legal considerations regarding who may access individual genomic and other data, and how that data is used, are of paramount concern. In addition, rules governing the use of patient data for research purposes (often called "secondary use," as the data is used beyond the scope of immediate clinical care) are critical. Secondary use requires a balance between a person's right to privacy and the need to create a healthcare system where every patient encounter can be an opportunity to improve care. Efforts to achieve such a balance can be aided by improved informed consent and risk communication, and by robust data deidentification and synthesis techniques. The relative cost of Precision Medicine may be high, due to the technology required and the expense of developing individualized medicines and treatments. However, cost savings are also possible, as ineffective treatments may be avoided for some patients. Ensuring access to Precision Medicine for everyone is critical, so that disparities in health care outcomes are not exacerbated. Another potentially problematic aspect of Precision Medicine, from an ethical standpoint, is the use of genomic information that predicts disease where there is no actionable treatment or preventative available; advance knowledge of an untreatable condition may reduce the quality of life. The question of when people should be informed of their risk of untreatable disease promises to continue to present thorny ethical issues.

Multi-omics Science Assessing multiple biomolecules can enable a deeper understanding of health and disease We are increasingly recognizing that our individual variations in the form, function, and complexity of the interaction of our biomolecular parts translate into unique health requirements and risk of disease. Even diseases once presumed to be simple, in the sense that a specific gene was thought to cause the disease, are now being recognized as more complex in terms of both severity, and in terms of potential for treatment in light of environmental factors like diet. Accordingly, the precision-based and personalized maintenance of health, and the diagnosis and treatment of disease, requires the coordinated collection and analysis of so-called “multi-omics” datasets that are culled from tissue. “Omics” approaches to biomedicine (involving fields that end in “-omics”) comprehensively assess biomolecules like genes and proteins at a scale equal to entire cells and organisms. That means that while genetics is the study of the form and function of specific genes, genomics is a high-throughput interrogation of all of the genes in an organism; transcriptomics is meanwhile the system-wide study of gene expression, while metabolomics relates to metabolites (the products of metabolism, such as amino acids), and proteomics are tied to proteins. The application of machine learning and other statistical patternrecognition tools to multi-omics datasets can facilitate a shift from reactive medicine to a fundamentally proactive form of predictive and precision health.

21 November 2020 Many of today’s biological innovations are complex, and we need to understand them fully to gauge their impact on our lives and societies. Only by working together can governments, scientists, businesses, and the public unleash the power of biology for good while effectively managing the risks.
Researchers report having observed the RNA folding structures of the SARS-CoV2 genome with which the virus controls the infection process. Since these structures are very similar among various beta corona viruses, the scientists not only laid the foundation for the targeted development of novel drugs for treating COVID-19, but also for future occurrences of infection with new corona viruses that may develop in the future.

A Precise Approach to Prevention Systems-level approaches can better enable disease prevention and control Simplified problem solving can result in incomplete solutions, when it comes to complex biological or life science-related phenomena. By way of contrast, systems science methods assess complex problems comprehensively, by analysing interactions that influence or predispose the ways that living things are built and function. The need for systems-based approaches is particularly pressing when it comes to evaluating factors that influence human health and well-being - because the onset of disease is usually the result of a complex interplay of factors including individual genomic profile, clinical phenotype (or the interaction between a genetic makeup and the environment), behaviour, social conditions, and the environment. The delivery of Precision Medicine should involve not only more precise approaches to the diagnosis and treatment of disease, but also to the prevention and control of related factors prior to the onset of disease. As our ability to measure factors that impact health and wellbeing improves, we must also develop systems-based scientific techniques that help us understand how data can be used to better support health and wellness. A genuinely improved understanding will require multi-disciplinary approaches that cross organizational boundaries, and the application of biomedical informatics and data science theories and methods. In addition, the incentives and drivers underpinning current healthcare delivery models will need to be realigned, in order to better engage care providers in the promotion of health and well-being that goes beyond hospitals and clinics. Ultimately, the use of systems science to deliver personalized approaches to health promotion should disrupt the current healthcare delivery system, lead to better outcomes, and reduce the fiscal and social burdens associated with disease.

Big data can help doctors predict which COVID patients will become seriously ill
Five serendipitous medical discoveries – starting with the Oxford vaccine dose 24 November 2020
19 January 2021 You might assume that all great medical discoveries are the result of deliberate action on the part of scientists. You’d be wrong. Many great discoveries are the result of accidents, mistakes and chance. Here are five of the best, starting with the most recent.
The pandemic continues to pose huge challenges to health services worldwide. Hospitals are in crisis as the pace of new COVID-19 cases outstrips their capacity. What makes things particularly difficult is that the coronavirus doesn’t affect everyone in the same way. Being able to better predict which patients will get seriously ill would allow hospitals to use their stretched resources more effectively. Armed with such information, hospitals could stop admitting patients who are at low risk of deteriorating and avoid administering unnecessary treatments.

Take Racism Out of Medical Algorithms 01 December 2020 COVID-19 has wreaked havoc on Black and Indigenous communities and other people of color, and U.S. medical institutions should be doing everything they can to root out and eliminate entrenched racial inequities. Yet many of the screening assessments used in health care are exacerbating racism in medicine, automatically and erroneously changing the scores given to people of color in ways that can deny them needed treatment. These race-based scoring adjustments to evaluations are all too common in modern medicine, particularly in the U.S. To determine the chances of death for a patient with heart failure, for example, a physician following the American Heart Association's guidelines would use factors such as age, heart rate and systolic blood pressure to calculate a risk score, which helps to determine treatment.

Data Into Action Making use of big data can generate useful insights and improve health care Biomedical informatics and data science help to translate data into actionable insights, which can in turn accelerate scientific discovery, improve care for individual patients, and impact the health of entire populations. These disciplines can intersect with the computational, quantitative, health, life, social, and behavioural sciences in formidable ways. In the context of Precision Medicine, often referred to as Personalized Medicine, the use of biomedical informatics and data science theories, methods, and tools have become increasingly critical. This is particularly true as we seek to advance our collective understanding of how bio-molecules, clinical features, and environmental factors correlate with disease risk, diagnoses, and the planning of treatment - and, perhaps even more importantly, how these features correlate with the maintenance of health before the onset of disease. Recent advances in artificial intelligence, machine learning, mobile computing, sensors, and human-computer interaction are extending the scope of data and analytical methods in ways that better enable the delivery of Precision Medicine. This has only amplified the unique and central role played by biomedical informatics in improving the health of entire populations.

A New Way to Probe DNA Biological organisms will be a crucial testing ground for understanding genetic variations underlying disease In order to determine if a particular DNA sequence variant contributes to a disorder or disease state, modern genomics has mostly depended on statistical methods - which show a correlation between a sequence variant and a disease. However, the next, big step in the genomic revolution will be the direct testing of sequence variants in appropriate biological organisms, to determine the effects on these organisms. This new testing approach includes sequence variants that are being investigated for the primary causation of genetic disease, as well as for genetic modifiers (genes that can affect or interfere with other genes). The investigation of genetic modifiers in particular can enable us to better understand the variation (in terms of clinical severity) of a wide variety of disorders. This information in turn has enormous potential to help determine which affected individuals should be aggressively targeted for therapeutic intervention, and which should instead receive minimal, or even no intervention. CRISPR technology, used for gene editing, has meanwhile enabled the rapid introduction of genetic variants into multiple organisms. Mammalian cell lines, simple model organisms such as yeast, algae, worms, fruit flies, mouse cells, and stem cells that can regenerate indefinitely, will all be essential for this approach. They may foster a deeper understanding of how putative sequence variants perturb cellular homeostasis, while revealing novel targets for therapeutic intervention and opening up entirely new areas of biological investigation.

Using new nanoimaging technology we show that the cell wall polymer pectin can independently expand plant cells. Similar biochemical 'self-expansion' of extracellular polymers in different kingdoms may change our vision of life beyond the plasma membrane.

The Cost of Precision Medicine Precision Medicine potentially offers a way to reduce costs, but challenges remain Although Precision Medicine, also referred to as Personalized Medicine, is unlikely to significantly reduce health care costs in the near future, there have been notable exceptions that provide a glimpse of its potential. The genomic characterization of certain cancers, for example, has led to improved molecular diagnostics and specific therapeutics that target unique tumour susceptibilities, illustrating a path forward to delivering more cost-effective, high-quality care. The increasingly routine use of genomic data, accurate clinical phenotyping (measuring the interaction between oneâ€™s genetic makeup and the environment), novel biomarkers of disease, and precise targetbased therapies all promise to transform the healthcare sector. That in turn should improve health outcomes, lead to a better understanding of disease risks, and eliminate the use of imprecise, expensive diagnostic procedures and ineffective therapies. Ultimately, these changes will likely decrease overall health care costs, and enhance value. However, we have yet to develop a reliable way to routinely integrate these technologies. While the capability and cost of generating high-quality DNA sequence information has improved exponentially, the annotation of genes, regulatory elements, DNA variants, and post-translational protein modifications lag behind. In addition, our understanding of the complex molecular pathways occurring within cells and organs, and their relationships to human development, ageing, disease, and environment remain rudimentary.

Engineering immune responses 27 November 2020
12 January 2021 Cytokines mediate various immune responses and have potential as drugs to treat cancer and other diseases. However, cytokines have diverse and competing roles; although some cytokine therapies are approved, they come with side effects and their efficacy can be limited.

They discuss improving on naturally occurring cytokines, engineering cytokine-signaling circuits for use with engineered cell therapies, and the possibility of designing cytokines that do not exist naturally. If efficacious, such approaches could improve the potency of cytokines as drugs and add to our understanding of cytokine-based communication. .

Today, stem cell biology and tissue engineering are turning fiction into reality with the advent of organoids: tiny lab-grown tissues and organs that are anatomically correct and physiologically functional. The appeal of organoids is obvious.

Redefining Health and Disease Diseases are being reclassified, thanks to the integration of “omics” Nosology, the medicinal science that deals with the classification of disease, is embracing the technological revolution of omics: the fields that end in “-omics.” Genomics, for example, is emerging as a powerful tool that can be used in the classification of disease, and builds on previous technological advances that utilized anatomy and microbiology to define pathologic disease. Genomic information (about an individual’s genetic makeup) can enable us to categorize disease, understand pathology, and target treatment accordingly. Knowledge of each person’s unique DNA sequence is bound to further personalize healthcare and treatment decisions. With advances in genomic science, ailments that once seemed dissimilar are being joined together under a single focus. And, what were once thought to be uniform diseases are being differentiated. For example, we can now define cancer based on aberrant genomic signatures, rather than simply on the anatomical origin of a tumour. Another example: cystic fibrosis can result from more than 900 mutations in the CTFR gene, and a drug has been developed that is particularly effective at addressing a specific, cystic fibrosis-related mutation. Rapid and relatively inexpensive genome sequencing, along with bioinformatics tools, are driving the new Personalized Medicine paradigm. The challenge will be to efficiently incorporate this genomic information into routine healthcare.

Preparing for Precision The healthcare workforce must be trained to deliver Personalized Medicine Better preparing the health care workforce to deal with the genomic information that makes Precision Medicine (or, "Personalized Medicine") possible is vital. A lot of accumulated genomic knowledge, or knowledge related to the genetic information included within a cell, will be embedded into pointof-care decision-analysis tools associated with electronic medical records. When genomic testing becomes routine, clinicians will not have to order a pharmacogenetic test and then wait for the results to arrive, in order to decide on a drug and dosage. Instead, a prescribing system will automatically search a database, find a patient's genomic results, and recommend the proper drug and dosage to use for a specific disease. Clinicians will not only need to know about disease, genomics, and pharmacogenetics - they will need to be able to explain to a patient why a certain treatment is being prescribed. Other competencies health care providers will need include an ability to recognize and order tests when there are indications that diagnosis and treatment would benefit from the use of genomic sequencing. Health providers will generally be expected to have an ability to explain fundamental genetic concepts, and to provide a referral to a genetic counsellor when necessary. Specific competencies must include knowledge about when to use sequencing data in order to improve differential diagnoses, formulate individualized disease management plans, and guide therapies according to pharmacogenetic data. Genomic information should be integrated into all levels of a health professionalâ€™s education, and his or her maintenance of certification. In addition, the current model of one health professional counselling a patient about a genetic test will be disrupted by advances in wholegenome sequencing technologies. That is because as the entire genome is sequenced, actionable genetic information beyond a specific test will become available. New methods to efficiently store and query this information in electronic medical records should be built, in order to provide point-of-service information to healthcare providers and patients.

07 January 2021
23 November 2020 Landry Signé, Mark Esposito, and Sanjeev Khagram underscore the urgent need for international rules and standards governing data to catch up with the accelerated diffusion of digital technologies during the COVID-19 pandemic.
Existing technologies for site-specific integration of kilobasesized DNA sequences in bacteria are limited by low efficiency, a reliance on recombination, the need for multiple vectors, and challenges in multiplexing. To address these shortcomings, we introduce a substantially improved version of our previously reported Tn7-like transposon from Vibrio cholerae, which uses a Type I-F CRISPR–Cas system for programmable, RNA-guided transposition. The optimized insertion of transposable elements by guide RNA–assisted targeting (INTEGRATE) system achieves highly accurate and marker-free DNA integration of up to 10 kilobases at ~100% efficiency in bacteria. Using multi-spacer CRISPR arrays, we achieved simultaneous multiplexed insertions in three genomic loci and facile, multi-loci deletions by combining orthogonal integrases and recombinases.

Ten patients treated with a CRISPR-based gene-editing therapy for the inherited blood disorders sickle cell disease and beta-thalassemia have shown a consistent and sustained response with manageable side effects, according to interim results from two clinical trials reported Saturday. Vertex Pharmaceuticals and CRISPR Therapeutics are jointly developing the one-time gene-editing treatment called CTX001 . After being given the therapy by infusion, all patients in both studies have been free from symptoms of the diseases and have not needed blood transfusions.
We have genetically engineered tobacco plants capable of producing their own light, a phenomenon never described in any plants in nature. In addition to its aesthetic potential, this could lead to significant advances in techniques for imaging and studying physiological processes in plants.
