Published in JMIR Aging, the randomized crossover trial revealed that the smart wheeled walker significantly improved walking speed, reduced exertion and boosted dynamic balance compared with a traditional 4-wheeled rollator. The study was led by Dr. Phurichaya Werasirirat, Dr. Pornpimol Muanjai, Dr. Oranat Sukkho, Dr. Nongnuch Luangpon and Dr. Juntip Namsawang from the Department of Physical Therapy at Burapha University in Thailand, alongside Dr. Audrius Snieckus from the Lithuanian Sports University. https://medicalxpress.com/news/2026-09-smart-walker-boosts-efficiency-dynamic.html Tue, 01 Sep 2026 15:20:08 EDT news707483647 Older adults living with several chronic diseases, a condition known as multimorbidity, may respond differently to interventions aimed at preventing disability, depending on the combination of diseases they have. A new study, published in Nature Aging and led by researchers at Karolinska Institutet and Università Cattolica del Sacro Cuore in Rome, suggests that looking at patterns of multimorbidity, rather than individual diseases alone, could help make prevention more personalized. https://medicalxpress.com/news/2026-08-disease-profiles-reveal-uneven-benefits.html Mon, 31 Aug 2026 14:00:10 EDT news707396402 In a tale of identities as divergent as "The Prince and the Pauper," a well-known cancer-causing gene also influences cells in a zombie-like state meant to prevent cancer. https://medicalxpress.com/news/2026-08-hidden-role-cell-senescent-cells.html Fri, 28 Aug 2026 13:00:05 EDT news707140501 UVA Health researchers have discovered how a form of delirium that often strikes older patients after surgery may set the stage for dementia—and identified a drug that could reverse the underlying brain changes. https://medicalxpress.com/news/2026-08-dementia-discovery-link-delirium-surgery.html Tue, 18 Aug 2026 10:20:06 EDT news706263902 Stopping statins in adults 75 and older with no history of heart disease or stroke does not increase the risk of death over three years compared with continuing statins, although "bad" cholesterol rose around 50% in those who stopped, according to a randomized controlled trial published in The Lancet Healthy Longevity. Statins are a key medication for the prevention of atherosclerotic cardiovascular disease, a specific type of cardiovascular disease caused by the buildup of fatty plaque (atherosclerosis) inside the arteries. https://medicalxpress.com/news/2026-08-adults-older-statins-similar-year.html Wed, 12 Aug 2026 11:40:09 EDT news705746206
