Pregnant women exposed to persistent organic pollutants, or POPs, had slightly smaller fetuses than women who haven’t been exposed to these chemicals, according to an analysis of ultrasound scans by researchers at the National Institutes of Health and other institutions.

Nano-sized vesicles released by certain bacteria that inhabit the vagina may protect against HIV infection, suggests a study of human cells and tissues by researchers at the National Institutes of Health and the University of Bologna, Italy. Known as extracellular vesicles, these bubble-like particles are produced by many kinds of cells and are thought to transport molecules from one cell to another.

John Bennet Robbins, M.D., co-developer of a vaccine that has spared thousands of small children from a major cause of death and intellectual disability, has passed away after a long illness. Dr. Robbins was chief of the Laboratory of Developmental and Molecular Immunity at the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD), before he retired in 2012. He was 86.

Children’s average daily time spent watching television or using a computer or mobile device increased from 53 minutes at age 12 months to more than 150 minutes at 3 years, according to an analysis by researchers at the National Institutes of Health and other institutions.

Among Asian/Pacific Islander women living in the United States, those who reside in ethnic enclaves—areas with a high concentration of residents of a similar ancestry—are less likely to have pregnancy or birth complications than those living in other areas, suggests a study by researchers at the National Institutes of Health and other institutions.

Feeling stressed was linked to lower chances of ovulation, conception, and pregnancy among women who had earlier experienced a pregnancy loss, according to an analysis by researchers at the NICHD.

Blood levels of omega-6 fatty acids produced in the body could influence the likelihood of developing gestational diabetes, suggests a study by researchers at the National Institutes of Health and other institutions. However, the researchers found no association with gestational diabetes from consuming foods containing omega-6 fatty acids, such as vegetable oils, nuts, and seeds.

Pregnant women who are exposed to higher air pollution levels during their second pregnancy, compared to their first one, may be at greater risk of preterm birth, according to researchers at the National Institutes of Health.

Exposure to high levels of certain common air pollutants in early pregnancy may increase the risk of pregnancy-induced high blood pressure, suggests an analysis by researchers at the Eunice Kennedy Shriver National Institute of Child Health and Human Development. In addition, exposure to a class of air pollutants known as volatile organic compounds in mid-pregnancy may increase the risk for preeclampsia, a potentially fatal disorder of pregnancy affecting blood pressure and kidney function.

A high genetic risk score for cholesterol and other blood lipids among pregnant women is linked to fetal weight, but varies according to the mother’s racial and ethnic group and obesity status, suggests an analysis by researchers at the Eunice Kennedy Shriver National Institute of Child Health and Human Development.

Infants born to women exposed to high levels of air pollution in the week before delivery are more likely to be admitted to a newborn intensive care unit (NICU), suggests an analysis by researchers at the National Institutes of Health.

Women who have gestational, or pregnancy-related, diabetes may be more likely to develop a potentially serious build up of fat in the liver later in life, suggests an analysis by researchers at the National Institutes of Health and other institutions. The researchers found that 9 to 16 years after pregnancy, women who had gestational diabetes have high levels of liver enzymes associated with the accumulation of fat, which could place them at risk of liver damage and liver failure.

A high genetic risk of obesity among pregnant women is linked to fetal weight, but varies according to race, fetal sex, and other factors, according to a study by researchers at the NICHD.

Acceptance and support from communities and families appear to lessen the toll of mental health conditions experienced by former child soldiers transitioning to early adulthood, according to a study by researchers at the National Institutes of Health and other institutions.

NICHD was established more than 50 years ago to help understand maternal health and improve pregnancy outcomes. These selected advances highlight NICHD’s contributions to advancing the health and well-being of pregnant women, mothers, and families everywhere.

Taking a folic acid supplement daily before pregnancy may reduce the risk of gestational, or pregnancy-related, diabetes, according to a study by researchers at the National Institutes of Health and other institutions.

Birth by emergency cesarean delivery is associated with a higher risk for wheezing (a possible indication of asthma) and food allergy, suggests an analysis funded by the NICHD. Children who were breast fed after cesarean delivery did not have an indication of higher asthma risk but did have an elevated risk for food allergy.
