GLP-1 Drugs and AMD: What We've Learned So Far

Med Page Today November 29, 2025
MedPage Today reports that some studies suggest GLP-1 drugs might reduce the risk of age-related macular degeneration, but there are also hints that they could make progression to advanced AMD more likely. "In truth, it's all still a mystery," Abhimanyu Ahuja, M.D., says. So far "findings are observational. So while the association appears very strong and consistent, the biological mechanism and whether the relationship is causal remain unknown."

Whooping cough cases remain elevated as vaccination rates drop

PBS November 29, 2025
Lorne Walker, M.D., talks with PBS Newshour about the rise in cases of pertussis, or whooping cough, across the country. He says, “Unfortunately, the rates of vaccination against whooping cough have been falling for years, even going back prior to the COVID pandemic. Currently in Oregon, one out of every five two-year-olds hasn’t completed their whooping cough series of vaccinations, and one out of every ten kindergarteners, who are starting school and being exposed to lots of other kids and people, are not up to date on their whooping cough vaccines. We’re pretty confident that the low rates of vaccination are the key risk factor for having this high number of cases.”

Amniotic Fluid Spills Its Secrets in Fetal Development

The Scientist November 27, 2025
The Scientist reports on OHSU research that aims to understand how amniotic fluid changes through pregnancy and what advancements it could support in prenatal and preterm care. Jamie Lo, M.D., says, “We all understand how important the placenta is in terms of that prenatal environment and shaping fetal development. What we haven't really delved into is the amniotic fluid, which is kind of equally important in its role in shaping fetal development.”

Marie Boller, MD, highlights racial gaps in cesarean birth

Contemporary OB/GYN November 25, 2025
Recent OHSU research highlights persistent and widening racial disparities in cesarean birth rates in the United States. Marie Boller, M.D., says, “Patient-centered care is essential for improving birth outcomes and ensuring that cesarean decisions are made for the right reasons. Care plans must be individualized, with patients meaningfully involved in conversations about their options.”

Study Links Sleep Apnea With Parkinson’s Disease

The Wall Street Journal November 25, 2025
OHSU research finds people with untreated obstructive sleep apnea have a higher risk of developing Parkinson’s disease. Lee Neilson, M.D., says, “If you stop breathing and oxygen is not at a normal level, your neurons are probably not functioning at a normal level either … Add that up night after night, year after year, and it may explain why fixing the problem by using CPAP may build in some resilience against neurodegenerative conditions, including Parkinson’s."

Untreated Sleep Apnea Could Greatly Raise Odds for Parkinson's
