Should I avoid lettuce because of cyclosporiasis?

Cyclosporiasis, a parasitic infection linked to contaminated produce such as lettuce and raspberries, has been reported in 41 states and can cause severe diarrhea and dehydration. While some patients have required hospitalization for IV fluids, the illness is treatable with antibiotics, and health officials continue to investigate the source of the outbreak. To reduce risk, experts recommend thoroughly washing produce, removing outer lettuce leaves, and avoiding prepackaged salads when possible. Mike Cirigliano, MD, a professor of General Internal Medicine, urged people not to overreact. He added that most cases can be managed with appropriate medical care.

Scientists find potential link between GLP-1 use and hair loss

A new analysis of diabetes patients using GLP-1 medications showed that they were more likely to lose their hair than patients taking other common treatments. “These findings also highlight the need for ongoing surveillance of dermatological adverse events in GLP-1 receptor agonist users,” wrote study lead author Yong Chen, PhD, a professor of Biostatistics, George Cotsarelis, MD, chair of Dermatology and the Milton Bixler Hartzell Professor of Dermatology, and David Asch, MD, MBA, a professor of Medicine, Medical Ethics & Health Policy, and senior vice president for Strategic Initiatives, and their colleagues.

Penn Medicine crisis center cuts psychiatric ED consults 80 percent in 6 months

Patty Inacker, vice president of Behavioral Health, and Stephanie Hollister, MSN, RN, assistant vice president of Behavioral Health, discussed how Penn Medicine’s crisis response center at HUP Cedar Avenue dramatically reduced psychiatric emergency department consults by over 80 percent within six months.

The risk of contracting HIV from the dentist

NBC10 reported on a Philadelphia dentist who was suspended from practicing by the Pennsylvania Board of Dentistry for unsafe infection practices and who allegedly put patients at risk for HIV and hepatitis. Contracting HIV or hepatitis from a dental appointment is extremely uncommon but not out of the question, said Robert Gross, MD, a professor of Infectious Diseases, who was not involved in this situation. “You want no risk,” he said.

Semaglutide benefits for patients last beyond first year of intake, study finds

A Penn Medicine study shows that patients taking semaglutide continue to experience meaningful appetite control and reduced calorie intake even after more than a year of treatment, helping sustain weight loss even as food noise begins to increase. “Many patients worry that their medication has stopped working if they notice some return of hunger after the first several months,” said Jena Shaw Tronieri, PhD, a senior research investigator at the Center for Weight and Eating Disorders. “Our findings show that even when people feel some of those sensations returning, semaglutide continues to help them eat less. That sustained reduction in calorie intake appears to be a key reason why weight loss is maintained over time.”

Uncommon autonomic tachycardia syndrome linked to classic dermatomyositis

New Penn Medicine research found that nearly 1 in 20 people with dermatomyositis, a rare autoimmune disease that affects the muscles and skin, also have postural orthostatic tachycardia syndrome (POTS), a condition that causes a sharp increase in heart rate after standing. While researchers are still working to understand what causes POTS, the connection to dermatomyositis could provide new insights into the disorder, said study author Victoria Werth, MD, a professor of Dermatology.

Noninvasive testing, AI set to refine colorectal cancer screening

New guidelines from the American Cancer Society on screening for colorectal cancer are providing doctors with a wide variety of options but also causing some to question what the right methods are for the right situations. Shivan Mehta, MD, MBA, MSHP, associate chief innovation officer and an associate professor of Gastroenterology, discussed some of the options in use. “We all have a part to play in reducing the burden of colorectal cancer,” he said.
