​For freshmen with food allergies, the college dining hall can be a dangerous place. Connie Diekman, director of university nutrition at Washington University in St. Louis and a leading national expert, encourages new students to enlist campus dietitian and food service providers to help them stay safe.​

A new study in JAMA Psychiatry shows that therapy provided via telephone for older adults in rural areas is effective in treating anxiety disorder. In an accompanying editorial, Eric J. Lenze, MD, of Washington University School of Medicine in St. Louis, wrote that the health-care system lacks the capacity to help the growing elderly population and that relying too heavily on sedative medications isn’t the answer.​

Women who have gastric bypass surgery to lose weight should keep a close eye on their alcohol consumption, according to a study at Washington University School of Medicine in St. Louis. The researchers found that changes in how alcohol is metabolized after surgery can speed its delivery into the bloodstream, resulting in earlier and higher peaks in blood-alcohol levels.

During a retreat this summer on the Medical Campus, department heads, division directors and other senior leaders at Washington University School of Medicine explored unconscious bias and how to diminish its impact in medical environments.

The greatest risk factor for Alzheimer’s disease is advancing age. Researchers at Washington University School of Medicine in St. Louis have identified some of the key changes in the aging brain that lead to the increased risk. The changes center on amyloid beta 42, a main ingredient of Alzheimer’s brain plaques.​

Researchers at Washington University School of Medicine in St. Louis, led by Eric J. Lenze, MD, have received a $15 million grant to study strategies — including exercise, health education, meditation and yoga — aimed at helping older adults prevent or reverse typical age-related cognitive declines.

Two new studies explain why some parasite infections, such as those common in developing countries, sometimes can’t be cured with standard treatments. The research shows the parasite Leishmania — which infects 12 million people worldwide — often harbors a virus that helps the parasite survive treatments.

Calming a neural circuit in the brain can alleviate stress in mice, according to new research at Washington University School of Medicine in St. Louis that lays the foundation for understanding stress and anxiety in people. The researchers also showed they could shine a light into the brain to activate the stress response in mice that had not been exposed to stressful situations.

Researchers led by Gregory Storch, MD, have developed a diagnostic test to quickly detect enterovirus D68 (EV-D68), a respiratory virus that caused unusually severe illness in children last summer and fall. The outbreak caused infections at an unprecedented rate, with over 1,000 confirmed cases and 14 reported deaths nationwide, according to the Centers for Disease Control and Prevention.

New insight into one of the most common inherited causes of brain tumors may help physicians diagnose and treat the learning disabilities that often accompany the condition, neurofibromotosis 1. The School of Medicine’s David H. Gutmann is the study’s senior author.
