Football-loving states slow to enact youth concussion laws

States with college teams in strong conferences, in particular the Southeastern Conference (SEC), were among the last to take up regulations on youth concussions, according to a recent study.

Link found between drought and HIV among women in less-developed countries

Current research predicts that by 2025, 1,800 million people are expected to be living in countries or regions with insufficient water resources, and models show increased severity of droughts in years to come. Food insecurity and other consequences of droughts will become intensified, influencing disease vulnerabilities among populations in less-developed countries. New research from Kelly Austin, associate professor of sociology at Lehigh University, explores how droughts shape gender inequalities in the HIV burden, indirectly through increased food insecurity.

Automatic deep-learning AI tool measures volume of cerebral ventricles on MRIs in children

Researchers from multiple institutions in North America have developed a fully automated, deep-learning (DL), artificial-intelligence clinical tool that can measure the volume of cerebral ventricles on magnetic resonance images (MRIs) in children within about 25 minutes. The ability to track ventricular volume over time in a clinical setting will prove invaluable in the treatment of children and adults with hydrocephalus. Details on the development of the tool and its validation are reported today in a new article, "Artificial intelligence for automatic cerebral ventricle segmentation and volume calculation: a clinical tool for the evaluation of pediatric hydrocephalus," by Jennifer L. Quon, MD, and colleagues, in the Journal of Neurosurgery: Pediatrics .
