Alzheimer’s risk factor and cognition

Vanderbilt researchers found that a protein with roles in innate immunity worsens memory at baseline in carriers of APOE-e4, the strongest genetic risk factor for Alzheimer’s disease, further implicating neuroinflammation in cognitive decline.

C. diff infections drop in children

The number of pediatric infections caused by Clostridioides difficile (C. diff) decreased from 2013 to 2019, likely due to an increase in antibiotic stewardship programs and improved hospital contact protocols, Vanderbilt researchers found.
