NIH Scientists Identify Maternal and Fetal Genes That Increase Preterm Birth Risk

Researchers at the National Institutes of Health have identified DNA variants in mothers and fetuses that appear to increase the risk for preterm labor and delivery. The DNA variants were in genes involved in the regulation of inflammation and of the extracellular matrix, the mesh-like material that holds cells within tissues.

“A substantial body of scientific evidence indicates that inflammatory hormones may play a significant role in the labor process,” said Alan E. Guttmacher, M.D., acting director of the NIH’s Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD). “The current findings add evidence that individual genetic variation in that response may account for why preterm labor occurs in some pregnancies and not in others.”

NHLBI Funds Preclinical Tests on Devices for Infants and Children with Congenital Heart Defects

The National Heart, Lung, and Blood Institute (NHLBI), part of the National Institutes of Health, has awarded four contracts totaling $23.6 million to begin preclinical testing of devices to help children born with congenital heart defects or those who develop heart failure. The four-year program is called Pumps for Kids, Infants, and Neonates (PumpKIN).

Each year in the United States, nearly 1,800 infants die as a result of congenital heart defects and another 350 develop heart disease, which leads to heart failure for many. Approximately 60 infants and children under 5 years old who are placed on the heart transplant waiting list die each year before receiving one. Mechanically assisted circulatory support could be used to sustain these young patients as they seek to recover or wait to receive a heart transplant.

SIDS Linked to Low Levels of Serotonin

The brains of infants who die of sudden infant death syndrome (SIDS) produce low levels of serotonin, a brain chemical that conveys messages between cells and plays a vital role in regulating breathing, heart rate, and sleep, reported researchers funded by the National Institutes of Health.

SIDS is the death of an infant before his or her first birthday that cannot be explained after a complete autopsy, an investigation of the scene and circumstances of the death, and a review of the medical history of the infant and of his or her family. According to the National Center for Health Statistics, SIDS is the third leading cause of infant death, claiming more than 2,300 lives in 2006.

Antibodies Against Abnormal Glycoproteins Identified as Possible Biomarkers for Cancer Detection

Scientists have found that cancer patients produce antibodies that target abnormal glycoproteins (proteins with sugar molecules attached) made by their tumors. The result of this work suggests that antitumor antibodies in the blood may provide a fruitful source of sensitive biomarkers for cancer detection. The study, supported in part by the National Cancer Institute (NCI), part of the National Institutes of Health, appears in the Feb. 15, 2010 issue of the journal Cancer Research.

NIA Funds Centers to Study Demography of Aging

The National Institute on Aging (NIA), part of the National Institutes of Health, today announced that it has committed more than $36.7 million over the next five years to support and expand its Centers on the Demography and Economics of Aging. The Centers form a network of universities and organizations leading innovative studies on the characteristics of the aging population. The awards, which include some support from the American Recovery and Reinvestment Act, renewed support for 11 Centers and established three new ones.
