Lorelei Mucci, associate professor of epidemiology at Harvard School of Public Health (HSPH), studies the factors that influence prostate cancer risk and progression. She answers three major questions about recent research findings and discoveries in the field that have generated confusion for men trying to make the right choice for their health.
Department of Health & Human Services (HHS) Secretary Kathleen Sebelius announced that the next National Coordinator for Health Information Technology is HSPH alumna Karen DeSalvo, SM ’02.

De Salvo is a graduate of the Clinical Epidemiology program in the department. Sebelius noted in her statement, “Dr. DeSalvo’s hands-on experience with health delivery system reform and HIT and its potential to improve health care and public health will be invaluable assets to the Office of the National Coordinator and the Department.”
“The latest results from the SPCG-4 trial indicate that surgery can not only improve survival, especially in men diagnosed at a younger age or with intermediate-risk disease, but also that surgery can reduce the burden of disease in terms of development of metastases and the need for palliative treatment,” said co-author Jennifer Rider, assistant professor in the Department of Epidemiology
A study completed by a collaborative team of researchers at the Harvard School of Public Health and Columbia’s Mailman School of Public Health pinpoints evidence that women who experience PTSD are more likely to battle obesity. The study was recently published in Jama Psychiatry and was lead by senior author Karestan Koenen. This study acknowledges PTSD as not only being a mental health issue by demonstrating the severe physical health effects it can have on those who suffer from it as well. “The good news from the study is that it appears that when PTSD symptoms abate, risk of becoming overweight or obese is also significantly reduced,” says first author Laura Kubzansky, professor of social and behavioral sciences at HSPH.

- “Sugar, Salt, and Supplements: Sorting the Science” - Epi faculty members discuss the public health implications of food-product label changes recently announced by the U.S. Food and Drug Administration at a HSPH Forum panel discussion.
- Several members of the department co-authored one of the American Journal of Epidemiology 2013 Articles of the Year, “Incidence of Adult-onset Asthma After Hypothetical Interventions on Body Mass Index and Physical Activity: An Application of the Parametric G-Formula”. The paper’s first author is Judith Garcia-Aymerich, who was a visiting scientist in the department when this paper was written. Co-authors include Raphaëlle Varraso, Goodarz Danaei, Carlos A. Camargo, Jr. and Miguel A. Hernan.
- Epi in Space- An exciting new study led by NASA’s Human Research Program and the National Space Biomedical Research Institute will fund several investigations into the molecular, physiological and psychological effects of spaceflight in an effort to better understand the health impacts of human space exploration. Identical twins Scott and Mark Kelly, both veteran astronauts, will be the focus of this study. Scott Kelly will live aboard the International Space Station for one year while his twin brother, Mark Kelly, remains on Earth as a control. PI Immaculata De Vivo and lab manager Pati Soule are collaborating with researchers at Colorado State University to analyze the effect of spaceflight on telomeres. Telomeres are stretches of DNA found at the end of chromosomes; they shorten over time as cells divide and are associated with aging, cancer, and a higher risk of death. The project, “Differential effects on telomeres and telomerase in twin astronauts associated with spaceflight” will study astronaut Scott Kelly’s telomeres during his year in space and compare them to his twin. The researchers are excited to be a part of this first-of-its-kind investigation.
- “Anger can break your heart” – People who have angry outbursts appear to be at increased risk of heart attack or stroke, especially within the first two hours of an outburst, according to a study by Harvard School of Public Health (HSPH), Beth Israel Deaconess Medical Center, and New York-Presbyterian Hospital researchers including lead author Elizabeth Mostofsky as well as Epi professor, Murray Mittleman . Those with cardiovascular disease (CVD) are at particular risk.
- New school meal standards significantly improve fruit and vegetable consumption- New federal standards launched in 2012 that require schools to offer healthier meals have led to increased fruit and vegetable consumption, according to a new study from Harvard School of Public Health (HSPH) researchers. The study, the first to examine school food consumption both before and after the standards went into effect, contradicts criticisms that the new standards have increased food waste. HSPH authors included Eric Rimm, senior author and associate professor in the departments of Epidemiology and Nutrition, and Paul Catalano, senior lecturer on biostatistics.

- Forced prostitution is finally being linked to higher risk of HIV and sexually transmitted disease infection in sex trafficking victims. “Involuntary sex work is not only a human rights crisis, but also exacts a devastating toll on health,” Kathleen Wirth, ScD ’11, wrote in a recent online opinion piece in the New York Times. Wirth is a research fellow in the Department of Epidemiology and the Botswana Harvard AIDS Institute Partnership in Gaborone, Botswana.
- The healthiest diets cost about $1.50 more per day than the least healthy diets, according to new research from Harvard School of Public Health (HSPH). The study was published online in BMJ (British Medical Journal) Open. “While healthier diets did cost more, the difference was smaller than many people might have expected. Over the course of a year, $1.50/day more for eating a healthy diet would increase food costs for one person by about $550 per year. This would represent a real burden for some families, and we need policies to help offset these costs. On the other hand, this price difference is very small in comparison to the economic costs of diet-related chronic diseases, which would be dramatically reduced by healthy diets.” said Dariush Mozaffarian, the study’s senior author and associate professor at HSPH and Harvard Medical School. Other HSPH authors included research fellows Ashkan Afshin (Department of Epidemiology) and Gitanjali Singh (Department of Nutrition).
