    A new “Year in Review” from international researchers takes stock of osteoarthritis (OA) science published between April 2024 and March 2025—and the message is mixed: the global burden keeps climbing, many injections and pills underperform in trials, but a weight‑management medicine shows notable gains for people with knee OA and obesity. The review screened 1,920…

  • Mpox Surge Triggers Global Alert — and Mental Health Is Part of the Emergency, Review Warns

    A new peer‑reviewed brief report argues that the world’s response to the current rise in mpox must treat mental health as a core part of outbreak control—not an afterthought.

    ,

    In a real‑world test of 1,672 X‑rays, a commercial AI tool nudged junior doctors’ accuracy from 87% to 90%, but it also added some false alarms—especially around growth plates.   What’s new Researchers at a German children’s hospital evaluated an approved fracture‑detection program on everyday emergency‑department X‑rays. The AI performed well on its own and, when…

  • Can an AI “stroke helmet” help paramedics? Crews say yes—but only if it earns trust and saves time

    Interviews with ambulance teams in Norway and Sweden suggest AI can support—never replace—the “clinical eye” in stroke care.   Why this matters Stroke treatment is a race against the clock. Paramedics must quickly judge whether symptoms point to a clot‑caused (ischemic) stroke or a bleed (hemorrhagic) and which hospital can treat it fastest. A new qualitative…

  • The False Belief That MMR Vaccines Cause Autism

    Vaccines are a critical tool in preventing infectious diseases and protecting public health(1). The measles, mumps, and rubella (MMR) vaccine is one of the most important vaccinations, as it protects against three serious viral infections(2). The vaccine is administered twice, once at 12 months of age and again between the ages of four and six.…
