Dean’s Seminar Series: The Rapid Decline in Adolescent Mental Health in the 21st Century: The Rapid Decline in Adolescent Mental Health in the 21st Century: Magnitude, Causes, and Public Health Implications @ Peterson Hall 1912/1913
Jan 27 @ 12:00 pm – 1:00 pm

Speaker: Katherine M. Keyes,  Ph.D., M.P.H.
Associate Professor, Department of Epidemiology & Co-Director, Psychiatric Epidemiology Training Program
Mailman School of Public Health,  Columbia University

Abstract: Recorded suicide among adolescent girls has tripled in the past decade, and suicide among adolescent boys had doubled. These increases underlie concomitant increases in hospitalized suicide attempts. Additionally, increases in three independent, national-representative survey data sources of US adolescents have documented unprecedented increases in suicidal thoughts and reported attempts, major depressive episodes, depressive symptoms, loneliness, and low self-esteem, with all increases occurring since 2012.  Across these data sources, increases are faster among girls than boys. The consistency of findings across data sources, outcomes, self-report and administrative records, indicates that these increases are likely not due to methodological artifact, requiring strong epidemiological studies that elucidate causes of the increases, reasons for gender differences, and identification of groups within gender that are at higher risk. Existing evidence has tested the hypothesis that use of digital technology underlies these increases, but to date the strongest evidence suggests a limited and nuanced role of new technologies in predicting depression and self-harm. Additional research has pointed to broader sociological trends in the experience of adolescence within a fractured political and precarious economic environment, indicating that research progress that is cross-disciplinary and engages a broad range of scholars will propel recommendations for intervention and prevention forward.

Dean’s Seminar Series: Integrated Nutrition Approach to Improving Personal, Population, and Planetary Health @ Peterson Hall 1912/1913
Feb 17 @ 12:00 pm – 1:00 pm

Speaker: Frank Hu, M.D., Ph.D., M.P.H.  Fredrick J. Stare Professor of Nutrition and Epidemiology, Chair, Department of Nutrition
Director of Boston Nutrition Obesity Research Center Epidemiology & Genetic Core
Co-Director, Program in Obesity Epidemiology and Prevention,  Harvard T.H. Chan School of Public Health

Abstract: The global chronic disease burden and the food production system’s enormous environmental impact are two pressing threats to personal, population and planetary health. Fortunately, dietary modifications can alleviate both of these threats. Healthful plant-based dietary patterns have been associated with lower risks of coronary heart disease and type 2 diabetes. Precision nutrition can provide insight into the mechanisms behind these associations by assessing individual characteristics such as the metabolome, genome and microbiome. While precision nutrition has future potential to provide personalized diets for disease prevention, the field is still developing and thus must be balanced with public health nutrition strategies. In addition to their health benefits, plant-based diets have less environmental impact than animal-based diets. Producing animal products, especially meat, is more energy-intensive than producing plant products. Shifting global dietary patterns towards diets higher in plant-based foods and lower in meat would likely have significant personal, population and planetary health benefits.

What do we know about the Chernobyl disaster? @ Merten Hall (formerly University Hall), 1201
Feb 20 @ 1:30 pm – 2:45 pm

Speaker: Professor Kate Brown

MIT Professor of Science, Technology, and Society Kate Brown will discuss Chernobyl in her talk titled “The Great Chernobyl Acceleration.”

What do we know about the Chernobyl disaster? Working through Soviet archives, Brown encountered many contradictory accounts of the catastrophe and its effects. Local doctors reported “a public health disaster” among people exposed to Chernobyl fallout. International experts refuted that claim. Realizing that though people and archives lie, trees probably don’t, Brown turned to scientists—biologists, foresters, physicians, and physicists—to help her understand the ecology of the greater Chernobyl territories. She learned that contaminants saturated local eco-systems long before the Chernobyl accident and continued long after the 1986 event. Brown argues that to call Chernobyl an “accident” is to sweep aside the decades of radiation exposure that rained down on the globe during the period of nuclear testing. Instead of a one-off accident, Brown argues that Chernobyl was a point of acceleration on a timeline of radioactive contamination that continues to this day.

Dean’s Seminar Series – Precision Discovery of Neuroimaging Biomarkers for Parkinson’s Disease @ Peterson Hall 1912/1913
Mar 2 @ 12:00 pm – 1:00 pm

Speaker: F. DuBois Bowman, Ph.D., M.S., Professor and Dean, School of Public Health,  University of Michigan

Abstract: Parkinson’s disease (PD) is a complex neurodegenerative disorder that manifests through hallmark motor symptoms, often accompanied by a range of non-motor symptoms.  There is a putative delay between the onset of the neurodegenerative process, marked by the death of dopamine-producing cells, and the onset of motor symptoms, creating an urgent need to develop biomarkers that may yield early PD detection. Neuroimaging offers a non-invasive approach to examine the utility of a vast number of functional and structural brain characteristics as biomarkers.  We present a statistical framework for analyzing neuroimaging data from multiple modalities to determine features that reliably distinguish PD patients from healthy control subjects. This pursuit involves precision discovery from ultra-high dimensional data.  Our approach builds on the statistical learning procedure elastic net, performing regularization and variable selection, while introducing additional criteria centering on parsimony and reproducibility.  We apply our methods to data from two studies of PD.  We demonstrate high accuracy, assessed via cross-validation, and identify brain regions in the basal ganglia and outer cortex that are implicated in the neurodegenerative PD process.

Bio: Dr. Bowman is the Dean of the School of Public Health. He earned a B.S. degree in mathematics from Morehouse College, where he was a member of the Phi Beta Kappa honor society.
