Time-restricted eating improves cognition in older women

Samāneh Farsijani, PhD, assistant professor of epidemiology at Pitt Public Health, provided expert perspective on new research suggesting time-restricted eating may improve certain aspects of cognitive function in older women. Farsijani emphasized that the findings are encouraging but preliminary, noting the study’s small size and the need for larger, more diverse studies before broader recommendations can be made.

How a study of diabetes prevention expanded the science of healthy aging

"What we're realizing is that we're not just studying diabetes anymore," said Elsa S. Strotmeyer, PhD, professor of epidemiology at Pitt Public Health and current principal investigator of the Diabetes Prevention Program Outcomes Study (DPPOS), a landmark study examining the long-term effects of lifestyle intervention and metformin on health and aging. "We're studying aging."

New Delhi metallo-beta-lactamase (NDM) gene

A resistance gene that defeats most available antibiotics Is turning up in more American hospitals

Unlike most hospital outbreaks, the New Delhi metallo-beta-lactamase (NDM) gene can spread between different bacteria on mobile DNA called plasmids, making it particularly difficult to contain. "The gene is inherently mobile," said recent epidemiology doctoral graduate Nathan Raabe. Alex Sundermann, assistant professor of epidemiology, added that bacteria readily acquire the gene because it enhances their ability to survive, contributing to the spread of highly drug-resistant infections.

Congo’s Ebola outbreak has killed over 1,000 people

University of Pittsburgh School of Public Health's Jean Nachega, associate professor of epidemiology, who is advising African health authorities, says he does not expect the Ebola outbreak in the Congo to reach the CDC’s worst-case scenario but cautioned that the challenges remain “huge.”

Fifty years after Ebola’s discovery, Pitt Public Health researcher says global preparedness gaps remain

Fifty years after Ebola was first identified, researchers say the world has made significant scientific progress, yet many of the same public health challenges continue to hinder outbreak response. “The current outbreak gave us an opportunity to look back at where we’ve been over the past 50 years and ask what lessons we’ve actually learned,” writes Jean B. Nachega, PhD, professor of epidemiology at Pitt Public Health, in the New England Journal of Medicine.
Epidemiology Assistant Professor Sharon Welburn

How Sharon Welburn found her passion for public health and teaching

Sharon Welburn (MPH, EPI ’13; PhD, EPI ’19) was first introduced to public health while working alongside epidemiologists in an injury center lab at the University of Alabama at Birmingham. “My team and I were conducting research on car crashes using driving simulators, and it allowed me to see firsthand how data and research can directly push policy,” said Welburn, now an assistant professor of epidemiology at Pitt Public Health.

Far less than one drink a day could raise your cancer risk, study finds

Having just 0.35 ounces of alcohol per day has been linked to a higher risk of cancers of the pharynx, colon, rectum, esophagus, breast, liver, pancreas and prostate. “If you do the math, the results of this study suggest that it’s not safe to drink even one standard drink every day,” says Natacha DeGenna, PhD, associate professor of psychiatry, clinical and translational science, and epidemiology at the University of Pittsburgh.

Nationwide trial: Whole blood and components equally effective in prehospital trauma care

Giving whole blood or the component parts of blood are equally effective options for paramedics and emergency medical technicians to use in treating patients with severe, traumatic bleeding before arriving at the hospital, according to a large, nationwide trial directed by University of Pittsburgh and UPMC clinicians and scientists. “Our thoughtful approach to the study design allowed us to not only answer the important question of the efficacy of whole blood compared to component therapy, but also to evaluate the health impact of an important public health question, the age of whole blood,” said senior author Stephen Wisniewski, PhD, professor of epidemiology and co-director of the Epidemiology Data Center at Pitt’s School of Public Health.

Improving Protections from Heart Disease for Women with Type 1 Diabetes

Rachel Miller, research associate professor of epidemiology, and her team are studying how patterns of risk factors beyond blood glucose (blood sugar) differ for men and women with type 1 diabetes across their lifespan, and how these differences affect heart disease and other diabetes complications. Their work revealed that women with type 1 diabetes experience a significant drop in diastolic blood pressure as early as their 20s, decades sooner than the decline that naturally comes with reaching menopause
