Contrary to popular belief, the postmenopausal ovary is not defunct. In a new study of ovaries from 28 women, scientists at Northwestern University and the Buck Institute for Research on Aging found that in the decades well past menopause, the ovary remains biologically active and continues to remodel with age, showing increased inflammation and changes in tissue structure. The study also found a molecular link between ovarian aging and cancer. The study is published in Aging Cell. (10/14)

While respiratory syncytial virus (RSV) remains so common that almost every child gets it before they turn 2 years old, it can cause serious illness in infants, leading to the hospitalization of up to three of every 100 infected infants. Maternal vaccination with RSVpreF (Abrysvo) protects newborns from getting the virus, yet relatively few moms in the United States and Europe have opted for it since its rollout in 2023, a study published last week in The Lancet Regional Health-Europe finds. (Holohan, 10/12)

Providing “labor guides” to pregnant women helps combat misinformation that an increasing number of patients are getting from social media or artificial intelligence, according to a recent study. Dr. Samuel Melville, a resident-physician in obstetrics and gynecology at Oregon Health & Science University and the lead author of the study, said he frequently hears patients quoting social media or AI when resisting medical interventions, such as inducing the pregnancy with medication to encourage stalled labor.

Lisa Wirsching knocked on strangers’ doors. She collected petition signatures at the farmers’ market. She approached her neighbors, asking them if she could talk to them about Idaho’s abortion laws, if they’d heard about Proposition 1 or if they knew how they planned to vote. (Luthra, 10/13)
