Adoption of lecanemab, a novel infusion treatment for Alzheimer’s disease (AD), has been disproportionately higher among patients who are male, white, from urban areas, and have higher socioeconomic status, highlighting how certain populations are more likely to access potentially breakthrough new therapies than others

A groundbreaking new study co-authored by Dr. L. Andrew Lyon, founding dean of Chapman University's Fowler School of Engineering, introduces an AI-powered smartphone app that noninvasively screens for anemia using a photo of a user’s fingernail. Published in PNAS, the study shows the app provides hemoglobin estimates comparable to traditional lab tests, with over 1.4 million tests conducted by 200,000+ users.

An estimated 83 million Americans and more than 2 billion people globally are at high risk for anemia—populations that stand to benefit significantly from this accessible screening tool. The app offers a low-cost, scalable solution that enhances access, especially in underserved and remote communities, while enabling real-time health monitoring and earlier intervention.

A study led by the Barcelona Institute for Global Health (ISGlobal), a centre supported by ”la Caixa” Foundation, in collaboration with the Clínic-IDIBAPS, has shown for the first time, how lung capacity evolves from childhood to old age. Until now, it was thought that lung function increased until it peaked at around 20–25 years of age, after which it stabilised. It was also thought that in later adulthood, lung function begins to decline as the lungs age. However, this model was based on studies that did not cover the whole life course. In contrast, the current study used an “accelerated cohort design”, meaning data from several cohort studies were combined to cover the desired age range.

About The Study: Although Medicare Advantage (MA) plans offer and directly market supplemental benefits for dental and vision services, veterans enrolled in MA used these services with the same frequency as veterans in traditional Medicare (TM). Moreover, MA plans spent only modestly more on dental services and vision services for veterans than TM, including for emergency dental services. After accounting for private insurance plans used by TM enrollees and out-of-pocket spending, total spending on dental services was no different for veterans in MA vs TM.
