the Inspiration of Excellence Award to Alan Braverman, MD, and Rebecca Braverman. Dr. Braverman, Director of the Marfan Syndrome and Aortopathy Center at Washington University School of Medicine and Barnes-Jewish Hospital, has a personal connection to Marfan syndrome: both his father and brother died from complications of the condition. Together, Alan and Rebecca have been longtime champions of the Foundation’s mission, co-founding the annual St. Louis HeartWorks gala in 2008 and often taking their two daughters to Marfan events around the country. “It’s not a job,” said Dr. Braverman. “It’s the way our lives are.”

“We’ve got an increasing population in age, but also in prevalence of cardiometabolic disease and non-direct cardiac conditions, so more people have orthopedic issues, or cerebral vascular issues, or kidney issues, and they all make it more complex for cardiac disease and elevate the risk,” said Thomas M. Maddox, MD, MSc, a professor of medicine at Washington University School of Medicine in St Louis. “On the supply side, we’ve got an aging cardiology workforce, there’s uneven geographic distribution, and people are retiring.”

William Bowen Professor of Medicine and Professor of Public Health Mark Huffman, MD, MPH, has been appointed to the advisory board of the Fogarty International Center at the National Institutes of Health (NIH).

For 2026, awards were considered across three project categories: clinical/translational, community-engaged research, and biostatistics, epidemiology, and research design.

When it comes to dealing with strokes, every second truly does matter. Nearly 2 million brain cells die each minute a stroke remains untreated. And every 40 seconds, someone in the U.S. has a stroke. 795,000 strokes happen each year and chances are if you have one stroke… you’re more than likely to have another one. Statistics show of those 795,000 strokes, one in four have had a previous stroke. And the majority of strokes that happen are ischemic strokes, in which blood flow to the brain is blocked.

In the wake of this tragic loss, Nicholas’s debate team held a fundraiser, coming together to raise awareness of HCM, a disease of the heart muscle that makes it harder for the heart to pump blood to the rest of the body.

Mass General Brigham researchers and collaborators from Washington University School of Medicine in St. Louis and Emory University’s Rollins School of Public Health pooled data from 99 countries and 810,635 adults to determine how many people worldwide may benefit from GLP-1 use. They found more than one in four adults would be eligible for GLP-1s for weight management, with women, older individuals, and low- and middle-income countries among the most eligible. These critical metrics could be formative in policy development to deploy GLP-1s around the world to tackle obesity and its comorbidities. Their results are published in a research letter in The Lancet Diabetes & Endocrinology.
