Researchers are more and more specializing in comorbidities amongst folks residing with HIV, reminiscent of heart problems and most cancers, to enhance their longevity as a result of there at the moment are efficient therapies for the virus.
“It was gratifying to see high-risk analysis members being included in NIH-funded analysis,” mentioned. Matthew Freiberg, MD, MSc, a research principal investigator, Dorothy and Laurence Grossman Chair in Cardiology and professor of Medication at VUMC. “They aren’t solely residing with HIV, but additionally have a excessive burden of hepatitis, multi-substance use and psychological well being points.
