Vitamin D May Benefit People With Mild Cognitive Impairment - Fisher Center for Alzheimer's Research Foundation

In aging adults, reduced balance is associated with fall-related injuries, nursing home admission and an increased risk of death. A new study in Investigative Ophthalmology & Visual Science found that certain measurable features of the retinal vasculature were linked to a higher likelihood of worsening balance, suggesting that retinal imaging may eventually help flag patients who could benefit from earlier intervention. The study drew on data from the Canadian Longitudinal Study on Aging, a large population-based cohort of older adults. Participants underwent retinal imaging and were followed over three years for changes in balance status. The researchers evaluated retinal vessel traits using digital fundus photographs and assessed whether those baseline characteristics predicted the later development of balance impairment, defined as the inability to stand on one leg unassisted for one minute. According to the authors, this study is the first to assess this relationship. The researchers used a deep learning algorithm called the Quantitative Analysis of Retinal Vessel Topology and Size (QUARTZ) to measure retinal vessel morphology.

Type 2 DiabetesSurvodutide Reduced Body Weight for Patients With Type 2 Diabetes and ObesityType 2 DiabetesSurvodutide Reduced Body Weight for Patients With Type 2 Diabetes and ObesityPublished: October 21, 2026The SYNCHRONIZE-2 trial is a multinational, double-blind phase 3 trial conducted by Sean Wharton, MD, PharmD, of McMaster University in Hamilton, Ontario, Canada, and colleagues to evaluate the investigational glucagon receptor–glucagon-like peptide-1 receptor dual agonist survodutide. For patients with both type 2 diabetes and obesity, Dr. Wharton and colleagues wrote, “Weight management may be the most effective therapy for type 2 diabetes.”This trial enrolled 752 patients with type 2 diabetes and a BMI of at least 27. Patients were randomly assigned on a 1-to-1-to-1 basis to receive 3.6 mg of survodutide (n=250), 6.0 mg of survodutide (n=251), or placebo (n = 251) by once-weekly injection. The primary end points were percent change in body weight and a reduction in body weight of at least 5% from baseline to week 76. The mean weight change at week 76 (treatment-regimen estimand) was –8.2% in the 3.6-mg group, –9.8% in the 6.0-mg group, and –3.9% in the placebo group.

Published: October 21, 2026 at 8:36a.m. EDTMy morning routine isn’t complete without two calming yet energizing cups of green tea. Not only is a cup of tea highly enjoyable, but it has long been associated with health benefits, including a lower risk of heart disease, stroke and dementia. Now, a new study published Wednesday in the Journal of Internal Medicine suggests that how people prepare and drink their tea could also influence their cardiovascular health. Over an average follow-up of about nine years, researchers documented more than 14,800 cases of diseases affecting the heart and blood vessels, such as heart attacks, strokes and peripheral artery disease, which involves narrowing of arteries supplying blood to the arms and legs. Researchers analyzed data from more than 485,000 Chinese adults ages 30 to 79. Participants reported their tea-drinking habits, including how frequently they drank tea, what type they preferred, how strong they brewed it, and how hot they drank it. To help us understand the findings and what they mean for heart health, I spoke with CNN wellness expert Dr. Leana Wen.
