To help neurologists, clinicians and families understand the current evidence for a new gene therapy for Duchenne muscular dystrophy called delandistrogene moxeparvovec, the American Academy of Neurology (AAN) has issued an Evidence in Focus article, published May 14, 2025, online in Neurology^®.

A transient ischemic attack, also known as a mini-stroke, is typically defined as a temporary blockage of blood flow to the brain that causes symptoms that go away within a day, but a new study finds that people who have this type of stroke may also have prolonged fatigue lasting up to one year. The study is published on May 14, 2025, online in Neurology^®, the medical journal of the American Academy of Neurology (AAN). The study does not prove that mini-strokes cause lasting fatigue; it only shows an association.

As the U.S. continues to face complex public health challenges, a new paper published by a researcher at Columbia University Mailman School of Public Health calls for a redefinition of the public health workforce—one that goes beyond traditional boundaries and acknowledges the growing number of professionals outside government agencies who contribute to public health.

Evidence is mounting that clinicians can treat serious genetic disorders prenatally by injecting medicine into the amniotic fluid, thus preventing damage that begins in utero.  

A multidisciplinary team of researchers has developed an artificial intelligence (AI) model that can predict acute child malnutrition in Kenya up to six months in advance. The tool offers governments and humanitarian organizations critical lead time to deliver life-saving food, health care, and supplies to at-risk areas.

The machine learning model outperforms traditional approaches by integrating clinical data from more than 17,000 Kenyan health facilities with satellite data on crop health and productivity. It achieves 89% accuracy when forecasting one month out and maintains 86% accuracy over six months — a significant improvement over simpler baseline models that rely only on recent historical child malnutrition prevalence trends.

A new study led by York University looking at the health data of nearly 15,000 people enrolled in a medically supervised weight-loss program found disparities among ethnic and sub-ethnic groups in how much weight they lost. Lead author, York University Faculty of Health Professor Jennifer Kuk, says the results show that the very broad ethnic categories typically examined in clinical settings may mask differences in sub-ethnic groups. Further, she says the findings suggest the need for understanding how socio-economic issues may come into play to better support Black, Middle Eastern, Latin and South Asian communities with their weight-loss.
