Traditional surgery (carotid endarterectomy) did not show the same benefit. The research is published in the New England Journal of Medicine. https://medicalxpress.com/news/2025-11-stenting-people-carotid-artery-narrowing.html Fri, 21 Nov 2025 13:40:04 EST news682954801 A pioneering preclinical study has shown that CAR T cell therapy—a personalized form of immunotherapy used in cancer treatment—could be a highly effective tool against atherosclerosis, the condition where a build-up of plaque in the arteries reduces blood flow, leading to heart attacks and strokes. https://medicalxpress.com/news/2025-11-car-strategy-common-heart-disease.html Fri, 21 Nov 2025 09:11:23 EST news682938677 For many years, older adult patients who fractured their hip typically spent most of their recovery time with orthopedic doctors, working to regain their strength and function. But for some of those patients, that care only addressed part of their health issue, explains Michael McDermott, MD, a national endocrinology expert in the University of Colorado Anschutz Department of Medicine. https://medicalxpress.com/news/2025-11-osteoporosis-undetected-untreated-doctors.html Thu, 20 Nov 2025 20:40:03 EST news682871901 Trials of a new cholesterol-lowering pill have shown promising results for people with heterozygous familial hypercholesterolemia (HeFH), a genetic disorder that leads to high levels of LDL cholesterol. https://medicalxpress.com/news/2025-11-cholesterol-lowering-pill-bad.html Wed, 19 Nov 2025 13:40:01 EST news682780173 Ultra-processed foods are displacing traditional foods and meals globally, degrading diet quality, and contributing to the rise of diet-related chronic diseases. https://medicalxpress.com/news/2025-11-ultra-food-consumption-driven-commercial.html Wed, 19 Nov 2025 10:01:05 EST news682768861 In a new study, 18- to 21-year-olds exposed to a diet high in ultra-processed foods were more likely to overeat—even when full. Young Americans are gaining weight. https://medicalxpress.com/news/2025-11-ultra-foods-linked-overeating-young.html Wed, 19 Nov 2025 03:00:02 EST news682687537 Postmenopausal osteoporosis is a condition that weakens bones, making them brittle and prone to fracture. Taking the hormone estradiol can reverse these effects, but it may also increase endometrial and uterine cancer risks. Researchers publishing in Nano Letters developed a two-layer shell to encapsulate the hormone so it bypasses the uterus and releases only within an osteoporotic bone. Tests of the drug-delivery system showed improved bone density in treated mice without uterine side effects. https://medicalxpress.com/news/2025-11-bone-estrogen-delivery-reverses-postmenopausal.html Tue, 18 Nov 2025 16:30:02 EST news682705801 A quality improvement program helped reduce "bad cholesterol" (LDL or low-density lipoprotein) levels among military veterans who have heart and blood vessel disease, according to a preliminary late-breaking science presentation at the American Heart Association's Scientific Sessions 2025, held Nov. 7–10, in New Orleans. https://medicalxpress.com/news/2025-11-ldl-cholesterol-veterans-health-resources.html Tue, 11 Nov 2025 09:36:06 EST news682076162 The cholesterol medication alirocumab, a PCSK9 inhibitor, combined with a statin appeared to reduce LDL cholesterol levels by more than 50% among patients after a heart transplant, according to a late-breaking science presentation today at the American Heart Association's Scientific Sessions 2025.
