Dr. Deepika Mohan, NIH Director’s New Innovator Awardee, led a study that showed “Video Game Improves Doctors’ Recognition and Triage of Severe Trauma Patients”.
Playing an adventure video game featuring a fictitious, young emergency physician treating severe trauma patients was better than text-based learning at priming real doctors to quickly recognize the patients who needed higher levels of care, according to a new trial led by the University of Pittsburgh School of Medicine.
“Physicians must make decisions quickly and with incomplete information. Each year, 30,000 preventable deaths occur after injury, in part because patients with severe injuries who initially present to non-trauma centers are not promptly transferred to a hospital that can provide appropriate care,” said lead author Deepika Mohan, M.D., M.P.H., assistant professor in Pitt’s departments of Critical Care Medicine and Surgery. “An hour of playing the video game recalibrated physicians’ brains to such a degree that, six months later, they were still out-performing their peers in recognizing severe trauma.” For the full article see “Efficacy of educational video game versus traditional educational apps at improving physician decision making in trauma triage: randomized controlled trial.” BMJ 2017;359:j5416

Researchers led by Isaac Kohane, MD, PhD reported on “Genetic Misdiagnoses and the Potential for Health Disparities”
A team led by Dr. Isaac Kohane at Harvard Medical School more closely examined the connection between hypertrophic cardiomyopathy and the DNA variants that previous studies in the medical literature had associated with the disease. The study was funded by NIH’s National Human Genome Research Institute (NHGRI), National Institute of Mental Health (NIMH), and National Library of Medicine (NLM). Results appeared on August 18, 2016, in New England Journal of Medicine.
The scientists analyzed DNA sequences from national databases that included more than 8,000 people. They identified five common DNA variants that were previously linked to hypertrophic cardiomyopathy. All five of these, the analysis found, were much more common in black Americans than in white Americans. All five were initially misclassified as disease-causing, they concluded; the new analysis found them likely to be harmless.

Researchers led by Graciela Gonzalez Hernandez, PhD demonstrate the value of social media mining for toxicovigilance
The use of social media mining for toxicovigilance is described in a series of articles by Dr. Gonzalez Hernandez and her research team. Social media is becoming increasingly popular as a platform for sharing personal health-related information. This information can be utilized for public health monitoring tasks, particularly for pharmacovigilance, via the use of natural language processing (NLP) techniques and other informatics strategies. In the first article, the team describes a scalable strategy for extracting complex medical concepts, with relatively high performance, from informal, user-generated content. In the second article, the research team demonstrates that these strategies can be applied to automatically detect posts indicating prescription medication abuse, allowing real-time monitoring and analysis of medication abuse. At the time of the award Dr. Gonzalez Hernandez was a New Investigator for NIH.

HealthMap Researchers led by John Brownstein, PhD and Maimuna Majumder, MPH reported “Low Vaccination Rates Fuel 2015 Measles Outbreak”.
Inadequate vaccine coverage is likely a driving force behind the ongoing Disneyland measles outbreak, according to calculations by a research team at Boston Children's Hospital. Their report, based on epidemiological data and published online by JAMA Pediatrics, indicates that vaccine coverage among the exposed populations is far below that necessary to keep the virus in check, and is the first to positively link measles vaccination rates and the ongoing outbreak.
By examining case numbers reported by the California Department of Public Health and current and historical case data captured by the HealthMap disease surveillance system, the researchers--led by Maimuna Majumder, MPH, and John Brownstein, PhD, of Boston Children's Informatics Program--estimate that the measles vaccination rate among the case clusters in California, Arizona and Illinois is between 50 and 86 percent, far below the 96 to 99 percent necessary to create a herd immunity effect.

Dr. Mandl and his colleagues created a score to help patients decide when to visit a clinician for the evaluation of a sore throat. Dr. Mandl and his team analyzed 71,776 patients aged 15 years or older with pharyngitis who visited a clinic from September 2006 to December 2008. If a patient aged 15 years or older with a sore throat did not visit a clinician when the new score estimated the likelihood of group A streptococcal (GAS) pharyngitis to be less than 10%, 203,000 visits would be avoided in the United States each year. Similarly, using the score, 8,500 patients with GAS pharyngitis who would have received antibiotics would not be treated with them. The study is published in the November 5, 2013 issue of the Annals of Internal Medicine. The study is related to research funded through Dr. Mandl's 2004 Presidential Early Career Award for Scientist and Engineers (PECASE), supported by NLM. (//www.nlm.nih.gov/ep/PECASE.html)

Dr. Jason Moore and his colleagues have helped to discover three unique genetic variations that influence body size and obesity in people of African ancestry. The study was published online in the April 2013 edition of Nature Genetics http://www.nature.com/ng/journal/vaop/ncurrent/full/ng.2608.htm. The large-scale genetic analysis demonstrated the utility of examining ancestrally diverse populations for clues as to why some groups seem more prone than others to physical problems such as obesity.
Despite their well-documented benefits, statins, drugs used to lower cholesterol, are commonly discontinued in routine care. Dr. Turchin and his team analyzed structured and free text clinical data from 107,835 patients between 2000-2008, who were prescribed a statin. They analyzed statin discontinuation and identified patients who had statin-related events (possible side effects to statins), whether people stopped taking their statins after these events, whether they later restarted a statin, and what happened if they did. The researchers found that more than 90 percent of patients who stopped taking statins because of an adverse reaction could tolerate the medication when tried again. The study is published in the April 2, 2013 issue of the Annals of Internal Medicine. This was a NIH Challenge Grant, supported by NLM with funds from the American Recovery and Reinvestment Act.

Jason H. Moore, PhD, a bioinformatics methodologist, is the Third Century Professor and Director of the Institute for Quantitative Biomedical Sciences at Dartmouth College. Dr. Moore’s NLM-funded bioinformatics research program focuses on the development, evaluation and application of computational methods for characterizing gene interactions in studies of common human diseases.
Board of Regents Presentation: "Machine Learning Approaches to the Genetic Analysis of Complex Traits." The sequencing of the human genome has made it possible to identify millions of rare and common variants across the genome that can be used to carry out genome-wide association studies (GWAS). The availability of massive amounts of GWAS data has necessitated the development of new biostatistical methods for quality control and data analysis. This work has been successful and has enabled the discovery of new associations. However, it is now recognized that most SNPs discovered via GWAS have very small effects on disease susceptibility and thus may not be suitable for improving healthcare through genetic testing. One likely explanation for the mixed results of GWAS is that the current biostatistical analysis paradigm is by design agnostic or unbiased in that it ignores all prior knowledge about disease pathobiology. Further, the linear modeling framework that is employed in GWAS often considers only one SNP at a time thus ignoring their genomic and environmental context. There is now a shift away from the biostatistical approach toward a more holistic bioinformatics approach that recognizes the complexity of the genotype-phenotype relationship that is characterized by significant heterogeneity and gene-gene and gene-environment interaction. Machine learning has an important role to play in addressing the complexity of the underlying genetic basis of common human diseases.
