NIH program provides a real-time risk assessment of variants of SARS-CoV-2

Faculty from the Departments of Microbiology, Medicine Genetics and Genomic Sciences, and Pathology and Molecular Cell-Based Medicine at the Icahn School of Medicine at Mount Sinai play key roles in a National Institutes of Health (NIH) program set up to provide a real-time risk assessment of variants of SARS-CoV-2, the virus that causes COVID-19. The program, called SARS-CoV-2 Assessment of Viral Evolution (SAVE) and described in a paper published March 31 in Nature, assesses how the variants might affect transmission, virulence, and resistance to both disease-induced (convalescent) and vaccine-induced immunity.

'Stroke-heart syndrome' may put stroke survivors at higher risk for future cardiovascular events

People who survive an ischemic stroke are much more likely to develop major heart complications during the first month after their stroke, and, as a result, they also have an increased risk of death, heart attack or another stroke within five years, compared to people who don't develop heart problems soon after a stroke, according to new research published today in Stroke, the peer-reviewed, flagship journal of the American Stroke Association, a division of the American Heart Association.
