Researchers derived pragmatic models that accurately distinguish mild, moderate and severe pneumonia in children, based on evidence from a study performed in 73 Emergency Departments (EDs) in 14 countries through the international Pediatric Emergency Research Network (PERN). The new predictive tools are intended to complement clinician judgement in deciding whether a child’s pneumonia warrants hospitalization or intensive care. The study was published in Lancet Child and Adolescent Health.

Women’s physical activity levels are less variable than men’s, according to a new study published in the Journal of Medical Internet Research. What’s more, women’s hormonal cycles did not have a noticeable impact on physical activity levels. 

About The Study: In 2023 and 2024, more Part D beneficiaries were affected by their insurer exiting the marketplace than in previous years. This increase could be associated with changes to Medicare Part D from the Inflation Reduction Act (IRA), which increased Part D plan sponsor financial liability. These IRA provisions were designed to lower out-of-pocket costs for Part D beneficiaries, but increased Part D plan exits could lead to more limited coverage options and less competitive Part D marketplaces. 

In a paper published in JAMA, the research team reports that 2.9 million beneficiaries lost their Part D insurer between 2024 and 2025, marking a sharp increase compared to the six years prior. 

Experiencing food insecurity in early childhood is associated with worse heart health two decades later, especially higher Body Mass Index (BMI). But participation in the Supplemental Nutrition Assistance Program (SNAP) may significantly mitigate that risk, reports a long-term Northwestern Medicine study published May 14 in JAMA Cardiology.
