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. (http://www.nlm.nih.gov/ep/PECASE.html)

Dr. Jason Moore
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.

Dr. Kwangsik Nho received the Silver Medallion Poster at the 2013 AMIA’s Summit on Translational Bioinformatics Conference (TBI). Dr. Nho is a current K99 award recipient and a former trainee of the NLM University-based Biomedical Informatics Research Training Program at University of Virginia. His poster entitled “Integration of bioinformatics and imaging informatics for identifying variants from whole-exome sequencing” was selected as top poster in the “Silver Medallion” poster framing session. Using a novel strategy to combine bioinformatics and imaging informatics methodologies, he performed whole-exome sequencing to identify functional non-synonymous variants in protein-coding regions associated with atrophy rate of hippocampal volume. This analysis of longitudinal change in hippocampal volume through an extreme-trait whole-exome sequencing design with extension via meta-analysis is considered as one of the first of its kind.

"Screening nonrandomized studies for medical systematic reviews: A comparative study of classifiers." Artificial Intelligence in Medicine: http://www.aiimjournal.com/article/S0933-3657(12)00062-0/abstract
In this study, Drs. Bekhuis and Demner-Fushman concluded that machine learning classifiers can help identify nonrandomized studies eligible for full-text screening by systematic reviewers. Optimization can markedly improve performance of classifiers. However, generalizability varies with the classifier. The number of citations to screen during a second independent pass through the citations can be substantially reduced.

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.
