Molecular imaging of C. diff infection
Sep. 30, 2021—C. difficile — the leading cause of hospital-associated intestinal infections — induces a rapid influx of bile acids into the gut, which could provide a novel target for blocking infection.
Vitamin D impact on disease biomarkers
Aug. 10, 2021—In a randomized controlled trial, vitamin D supplementation did not improve biomarkers for cardiovascular and metabolic disease.
American Heart Association honors Biaggioni’s research
Aug. 5, 2021—Italo Biaggioni, MD, professor of Medicine and Pharmacology, has been selected as a Distinguished Scientist of the American Heart Association for his contributions to cardiovascular and stroke research.
Probing statin-associated diseases with genetics
Jul. 12, 2021—Vanderbilt researchers used genetics tools and biobanks with linked electronic health records to explore the associations between statins and noncardiovascular diseases.
Heat for hypertension in autonomic failure
May. 25, 2021—Heat therapy could offer a novel nonpharmacologic approach for treating the overnight hypertension that affects patients with autonomic failure.
Study revises understanding of cancer metabolism
Apr. 7, 2021—Tumors consume glucose at high rates, but a team of Vanderbilt researchers has discovered that cancer cells themselves are not the culprit, upending models of cancer metabolism that have been developed and refined over the last 100 years.
HIV, diabetes and immune cells in fat
Mar. 18, 2021—In HIV-positive individuals with diabetes, immune cells in fat are more proinflammatory and cytotoxic and may represent a therapeutic target for diabetes.
Eye stroke is focus of American Heart Association statement
Mar. 18, 2021—The American Heart Association (AHA) recently issued a scientific statement, “Management of Central Retinal Artery Occlusion.” CRAO is a form of ischemic stroke characterized by acute and painless vision loss in one eye.
Gene variant and glucose metabolism
Feb. 18, 2021—Genetic variation that impacts glucose- and insulin-related signaling affects responses to type 2 diabetes treatments and warrants further study.
Mitochondrial stress and hypertension
Jan. 12, 2021—Oxidative stress and toxic products called isolevuglandins in mitochondria play a role in endothelial dysfunction and hypertension — and getting rid of them with a special “scavenger” molecule has therapeutic potential.
VHVI’s Brown, Agrawal receive American Heart Association awards
Dec. 10, 2020—Two Vanderbilt Heart and Vascular Institute researchers are receiving awards from the American Heart Association.
Depression and the brain-age gap
Oct. 19, 2020—Older depressed adults show accelerated brain aging, according to a new study from Vanderbilt researchers, who suggest that the effects of depression may speed the decline in cognitive functions in older individuals.
