A model may retain valuable medical knowledge, but in a controlled study using real hospital records, the same fine-tuning—the added training that adapts a model to a specific task—that improved diagnostic performance also made it more likely to reproduce material it had seen during training, including sensitive patient information. https://medicalxpress.com/news/2026-09-fine-tuning-medical-ai-diagnosis.html Mon, 14 Sep 2026 08:40:10 EDT news708593462 Researchers at Vanderbilt Health, UTHealth Houston and the University of North Carolina at Chapel Hill have identified early signs of cardiovascular-kidney-metabolic disease (CKMD) in children as young as 8 years old that potentially can be reversed with a new class of weight-loss drugs widely used by adults. https://medicalxpress.com/news/2026-09-early-blood-protein-clues-children.html Sun, 13 Sep 2026 09:00:06 EDT news708353097 Mayo Clinic researchers have found that artificial intelligence (AI)-enabled spatial analysis can identify patterns in routine pathology slides that may help clinicians identify which patients with pancreatic cancer are at greater risk of recurrence after treatment and surgery. https://medicalxpress.com/news/2026-09-ai-enabled-analysis-pathology-pancreatic.html Fri, 11 Sep 2026 13:00:02 EDT news708344041 The Society for Healthcare Epidemiology of America (SHEA) has published a new resource describing how diagnostic stewardship can improve patient outcomes, strengthen hospital quality metrics and reduce health care costs. https://medicalxpress.com/news/2026-09-resource-hospitals-business-case-diagnostic.html Fri, 11 Sep 2026 09:40:09 EDT news708328022 A city's sewers say a lot about its residents. Sick people often shed pathogens in their waste, adding traceable amounts of bacteria and viruses to wastewater. Testing that wastewater offers a simple, low-cost way to monitor the spread of disease—a practice that began with polio in the 1940s and became more widespread during the COVID-19 pandemic. Today, the CDC's wastewater monitoring program tests for a variety of common and emerging viruses. https://medicalxpress.com/news/2026-09-sewers-reveal-chlamydia-college-campus.html Thu, 10 Sep 2026 13:20:07 EDT news708264602 The way two mpox virus proteins change shape as they bind together acts like a switch that starts the process of viral replication, a study led by researchers at the Blavatnik Institute at Harvard Medical School reveals.
