This collaboration will promote safe infant sleep with and within American Indian and Alaska Native communities.

A treatment to move blood from the umbilical cord into an infant’s body may provide a safe option for preterm infants born after 28 weeks who need rapid support, suggests a study supported by the National Institutes of Health. Umbilical cord milking involves gently squeezing the cord between the thumb and forefinger and pushing the blood into the newborn’s abdomen. The new findings suggest that concerns raised by a previous study of infants born before 28 weeks—which concluded that umbilical cord milking might increase the risk of bleeding inside the brain—do not apply to preterm infants born after 28 weeks.

Using new ultrasound technology that can visualize and measure blood flow through extremely small blood vessels, researchers funded by the National Institutes of Health have tracked the placenta’s development from the merging of placental cells with blood vessels in the uterus to a fully formed organ. The images and data provide a reference for normal placental development to help with comparison studies, tracking of placental development in healthy pregnancies, and identification of placental disorders that may lead to low birth weight, preterm birth, and other complications.

A technique using near-infrared light to detect blood oxygen levels in the brain and abdomen may have potential for monitoring the health of preterm infants needing or given a blood transfusion.

The National Institutes of Health will award up to $2 million in cash prizes to accelerate development of diagnostic and monitoring technologies that improve fetal health outcomes in low-resource settings. The Fetal Monitoring Challenge calls on scientists, engineers, and clinicians around the country to submit their innovative approaches and compete for prizes and additional resources to support technology development and clinical impact. The challenge seeks innovation in point-of-care and home-based diagnostic and monitoring technologies that may reduce fetal health risk and loss during and after birth.

Extremely preterm infants fed fortified human milk grew longer and more rapidly and had larger head circumferences than infants fed unfortified human milk, according to a study funded by the National Institutes of Health. The findings provide support for future studies on the potential benefits of human milk fortification in preventing malnutrition among infants born at 28 weeks or younger.

A device known as a pessary, thought promising for reducing preterm birth risk due to a short cervix, appears no more effective than usual medical care, according to a study funded by the National Institutes of Health. A pessary is a rounded silicone device that fits around a cervix that has shortened, to keep it from opening and leading to miscarriage or preterm birth. The device is typically removed before the 37th week of pregnancy.

The Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) has announced new funding for participating centers in its Maternal-Fetal Medicine Units (MFMU) Network.

NIH-funded technique enables automatic detection of placental compartments, oxygen status and structural abnormalities.

Researchers know that children born to mothers who have depression in pregnancy are at risk for developmental delays but haven’t known why. Now, a National Institutes of Health study suggests that depression persisting after pregnancy and reduced breastfeeding may account for at least part of the increased risk. Based on their results, researchers conclude that physicians may be able to reduce this risk by offering treatment for depression both during and after pregnancy and by counseling new mothers on how to breastfeed successfully.

Mouse study improves understanding of events leading to preterm labor and birth

A bacterial species that causes chorioamnionitis—an infection of the placenta and fetal membranes that often leads to preterm birth—relies on a gene for metal tolerance to hijack immune cells, suggests a study in mice funded by the National Institutes of Health. The findings indicate that strategies to target the gene and its products could eliminate one of the most common causes of preterm birth.

Steroid treatment before birth appears to improve survival and reduce complications among extremely preterm infants, according to a study funded by the National Institutes of Health. Antenatal steroid therapy, given to women at risk of preterm delivery, causes the fetal lungs to mature and has been shown to improve survival and reduce complications among infants born from 24 to 34 weeks of pregnancy. However, previous studies of the treatment for infants born between the 22nd and 23rd week—those at greatest risk for death and disability—were inconclusive.

The National Institutes of Health is offering up to $8 million in cash prizes to accelerate development of technologies to improve maternal health outcomes for those who live in areas lacking access to maternity care.

A treatment to move blood from the umbilical cord into an infant’s body may improve the overall health of newborns classified as non-vigorous—limp, pale and with minimal breathing, suggests a study funded by the National Institutes of Health. The procedure, known as umbilical cord milking, involves gently squeezing the cord between the thumb and forefinger and slowly pushing the blood into the abdomen.

Researchers funded by the National Institutes of Health have identified a protein that allows the uterus to stretch to accommodate a developing fetus. When the protein is deactivated, the uterus begins the contractions culminating in labor. The findings raise the possibility of preventing preterm labor by developing drugs to target the protein.

The increase in pregnancy complications linked to air pollution exposure could result from the pollutants’ direct effects on the placenta, suggests a study in mice funded by the National Institutes of Health. Placentas of mice exposed to a mixture of common urban air pollutants before and during pregnancy were inflamed and had a loss of blood vessel cells. The study authors say the findings could provide insight into how air pollution might affect pregnancies and lead to strategies for preventing pregnancy complications.
