  • Semaglutide May Reduce Dementia Risk

    In a large nationwide population-based study, semaglutide significantly reduced Alzheimer’s disease-related dementia risk compared to insulin, metformin, and older glucagon-like peptide-1 receptor agonists in patients with type 2 diabetes.

  • Long-Term Peripheral Nerve Function in People with Well-Controlled Type 2 Diabetes

    The authors conducted a prospective observational study comparing the effect of early diagnosed, well-controlled type 2 diabetes on peripheral nerve function. Overall, they found similar rates of decline in nerve function in people with well-controlled diabetes compared to age- and sex-matched individuals with normal glucose tolerance. Given the similar decline in nerve function, the authors concluded that the course of diabetic sensorimotor neuropathy is influenced primarily by nerve function at the time of diagnosis and age-related physiological decline.

  • Examining Fecal Microbiota Transplant for Primary C. difficile Infection

    In a randomized controlled trial conducted in Norway, fecal microbiota transplantation (FMT) was noninferior to vancomycin for the treatment of primary Clostridioides difficile infection, with 66.7% of patients in the FMT group achieving clinical cure without recurrence compared to 61.2% in the vancomycin group over 60 days of follow-up.

  • Do Gowns Help Prevent Transmission of Respiratory Viruses?

    The authors examined various studies to look at the effectiveness of different kinds of gowns and materials in preventing viral infections. The results were mixed, with most studies demonstrating no good evidence that gowning helps in this regard.

  • Taletrectinib Capsules (Ibtrozi)

    The U.S. Food and Drug Administration has approved a potent, selective, next-generation ROS Proto-Oncogene 1 (ROS1) receptor tyrosine kinase inhibitor, taletrectinib, for the treatment of ROS1-positive non-small cell lung cancer.
