Results from a large NIH-supported study show that protein analyses taken during the first trimester of pregnancy did not improve predictions for identifying people at risk for experiencing conditions related to having high blood pressure, hypertension, during pregnancy. Since there is an urgent need to better predict people at risk for hypertensive disorders of pregnancy, researchers have been studying if proteins taken from blood or urine samples could provide this insight.

Results from a national survey indicate that many Americans, 61%, are unaware that primary care physicians can prescribe medications for opioid use disorder, and 13% incorrectly believed that they could not.

A large analysis of data from nearly 400,000 healthy U.S. adults followed for more than 20 years has found no association between regular multivitamin use and lower risk of death. The study, led by NCI researchers, was published June 26 in JAMA Network Open.

Researchers have, for the first time, visualized the full network of blood vessels across the cortex of awake mice, finding that blood vessels rhythmically expand and contract leading to “waves” washing across the surface of the brain. These NIH-funded findings improve understanding of how the brain receives blood, though the function of the waves remains a mystery.
