NHLBI-funded researchers from The University of Texas Health Science Center and other locations found evidence to support the use of a battlefield blood transfusion protocol for severely injured trauma patients. The study detailing these findings appears in the Journal of the American Medical Association.

NHLBI Media Availability: NHLBI Researchers Discover Never-Before-Seen Mode of Viral Transmission
WHAT: NHLBI-funded researchers have discovered a novel means by which viruses spread between cells: multiple polioviruses, a type of enterovirus, travel together within a membrane-enclosed sac, arriving together at a cell they then infect. This finding revises a central tenet of virology that viruses behave as independent infectious agents.
Study shows that iron supplementation after blood donation shortens hemoglobin recovery time
A National Institutes of Health-funded study comparing low dose iron supplementation to no supplementation in blood donors found that supplementation significantly reduced the time to recovery of post-donation lost iron and hemoglobin—an iron-rich protein that carries oxygen in red blood cells throughout the body.
The results of the Hemoglobin and Iron Recovery Study (HEIRS), supported by NIH’s National Heart, Lung, and Blood Institute (NHLBI), will appear Feb. 10 in the Journal of the American Medical Association.

DNA methylation levels change with age. Recent studies have identified biomarkers of chronological age based on DNA methylation levels. It is not yet known whether DNA methylation age captures aspects of biological age. The paper reports that DNA methylation-derived measures of accelerated ageing are heritable traits that predict mortality independently of health status, lifestyle factors, and known genetic factors. Researchers from the NHLBI's Framingham Heart Study were among the authors of this paper.
