Adults diagnosed with a concussion may be at about 50 per cent higher risk of a subsequent traffic crash.

Several longtime public health researchers warn that current U.S. immigration enforcement and deportation policies are producing widespread harm to physical and mental health, with family separation and the specters of fear and intimidation affecting the well-being of immigrant and non-immigrant communities.

The number of women undergoing tubal ligations — a surgical procedure that permanently prevents pregnancy — increased 51% across four academic medical centers in four states in the year after the Supreme Court decision in Dobbs v. Jackson Women’s Health Organization, according to a new study from researchers at Penn State College of Medicine, Albany Medical Center, University of South Florida and University of Tennessee Medical Center. Almost half of those seeking the procedure reported that their decision was somewhat or very related to the current political climate, even in states considered to be protective of abortion access.

Fewer than half of young adults with severely high low-density lipoprotein (LDL-C), or “bad” cholesterol, levels start taking a statin within five years of first high LDL-C measurement, according to a study published in JACC, the flagship journal of the American College of Cardiology, and presented at the American Heart Association’s 2025 Scientific Sessions. The 2018 ACC/AHA Cholesterol Guideline recommends a statin in patients with LDL-C over 190 mg/dL and these findings highlight significant care gaps in lipid management among adults aged 18 to 39, particularly those at high risk for premature atherosclerotic cardiovascular disease (ASCVD).
