‘No-touch’ vein harvesting significantly reduces the risk of graft failure up to three years after coronary artery bypass surgery compared with conventionally harvested vein grafts, finds a study from China published by The BMJ today.

Reduced levels of a critical protein are linked to devastating brain diseases like Alzheimer’s, frontotemporal dementia, and amyotrophic lateral sclerosis (ALS). Surprisingly, the protein shortage primarily affects the brain’s blood vessels.

In a study, published in JAMA Oncology, researchers at University of Michigan showed that the proportion of patients undergoing prostatectomy for the lowest-risk type of cancer dropped over fivefold between 2010 to 2024.

They concluded that efforts to increase active surveillance and improved diagnostic methods have helped more men avoid unnecessary surgery.

Researchers with the University of Calgary and the Chinese University of Hong Kong (CUHK) led an international collaboration that found inflammatory bowel disease (IBD) progresses through four predictable epidemiological stages as it spreads globally. Published in Nature, the study forecasts a major rise in IBD prevalence in Canada by 2045. Researchers say pinpointing where each region sits on the trajectory gives health-care systems a clear roadmap to prepare for IBD’s growing burden and tailor interventions—whether clinical, policy driven, or preventive today and in the decades to follow.
