NEJM This Week — November 13, 2025

In this episode, we look at new trials on deferring arterial catheterization in shock, beta-blocker use after myocardial infarction, and a treatment for triple-negative breast cancer. We review acromegaly. A case describes a man with dyspnea, edema, and pacemaker lead displacement. We explore perspectives on the burdens of primary care, the erosion of harm reduction, child health policy, and the meaning of hospice.
