A large international randomized trial found that 4 grams a day of omega-3 fish oil was associated with a 43% lower rate of serious cardiovascular events among adults receiving maintenance hemodialysis. The PISCES study enrolled 1,228 participants at 26 sites in Australia and Canada; results were presented at the American Society of Nephrology’s Kidney Week 2025 and published in The New England Journal of Medicine.
Brazil's Anvisa approved on Monday, February 2, 2026, the expansion of therapeutic indications for semaglutide, the active ingredient in Wegovy and Ozempic. Wegovy can now be used to reduce the risk of heart attacks and strokes in adults with cardiovascular disease and overweight, while Ozempic is indicated for type 2 diabetes associated with chronic kidney disease. The agency is also reviewing a request for an oral version of Wegovy.

A comprehensive review in Beverage Plant Research concludes that evidence from human studies most strongly supports an association between tea consumption—particularly green tea—and lower risks of cardiovascular disease, obesity, type 2 diabetes and some cancers, while calling evidence for brain and muscle benefits “promising” but less settled. The authors also caution that bottled and bubble tea products, which can include added sugar and other additives, may blunt tea’s potential advantages.
Researchers at the University of Barcelona have discovered that combining two existing medications, pemafibrate and telmisartan, significantly reduces liver fat in animal models of metabolic dysfunction-associated steatotic liver disease (MASLD). This approach could offer a safer treatment option for the condition, which affects about one in three adults worldwide. The findings highlight the potential of drug repurposing to address a disease with limited current therapies.
