Media Advisory: NIH-supported researchers create single-cell atlas of the placenta during term labor
Science Update: NIH-funded researchers link genetic variants to malformations in stillborn infants
Researchers linked malformations in stillborn infants to copy number variants—lengths of DNA in which hereditary material is duplicated or deleted. What they learned could lead provide information helpful to parents and for pregnancy care.
Science Update: Questionnaire could identify emotional responses leading to PTSD after childbirth, NIH-funded study suggests
A questionnaire detecting strong emotional responses to traumatic births could help identify new mothers at risk for developing childbirth-related post-traumatic stress disorder. It may lead to faster diagnosis—and treatment—of post traumatic stress disorder in new mothers.
Science Update: Cannabis use in pregnancy may impair placental function, suggests NIH-funded study
Pregnant people who tested positive for cannabis use were at 27% higher risk for conditions related to poor placental function—including hypertensive disorders of pregnancy, stillbirth, and growth restriction relative to gestational age—than pregnant people who tested negative.
Director's Corner: Reflecting on a Productive 2023
In 2023, NICHD continued its commitment to research to understand human development, improve reproductive health, promote women’s health, enhance the lives of children and adolescents, and optimize abilities for all. Highlights include steps toward reducing the global burden of maternal sepsis and establishing a standard treatment for opioid-exposed newborns.
Science Update: Widespread COVID-19 vaccination likely halted spike in preterm birth, NIH-funded analysis suggests
By late 2022, widespread COVID-19 vaccination of pregnant people likely halted a spike in the preterm birth rate that began at the start of the pandemic, suggests a new study. The findings underscore the need for pregnant people to keep current on COVID-19 vaccination.
Spotlight: Looking Back on NICHD in 2023
As we ring in 2024, we’d like to take a brief look back on our accomplishments during 2023. These activities illustrate the institute’s continued commitment to research and training in its mission areas.
Science Update: Maternal depression may age the placenta prematurely, NIH study suggests
Depression in early and mid-pregnancy seems to age the placenta more rapidly than not experiencing depression during pregnancy. Premature placental aging could account for higher rates of low birth weight, preterm birth, blood pressure disorders, diabetes, and other complications linked to depression in pregnancy, underscoring the need to diagnose and treat depression in pregnant people.
Director's Corner: Advancing Endometriosis Research
Endometriosis affects an estimated 10% of women, can cause severe pain and infertility, and typically has long delays in diagnosis. NICHD is accelerating efforts to definitively diagnose, prevent, and treat this chronic disease.
Spotlight: Scientific Advances from the Division of Intramural Research
The Division of Intramural Research provides fundamental knowledge about the nature and behavior of living systems through basic, clinical, and population-based research.
Science Update: Antibody treatment for cytomegalovirus appears to offer no benefit, suggests NIH-funded study
Two-year-old children showed no benefits from their mothers receiving antibodies that target cytomegalovirus (CMV) during pregnancy compared to those whose mothers received a placebo. Findings from this follow-up study were similar to the original, which also found no differences. Full effects of CMV infection during pregnancy may not appear until a child is two years old.
Science Update: Questionnaire may detect childbirth-related posttraumatic stress disorder, NIH-funded study suggests
An early study suggests that a questionnaire can detect posttraumatic stress disorder (PTSD) after childbirth with high probability. If large-scale studies verify its effectiveness, the questionnaire could provide a rapid and efficient method for postnatal PTSD screening, allowing timely referral for a thorough assessment and treatment.
Item of Interest: NICHD and CDC Partner on Healthy Native Babies Project
This collaboration will promote safe infant sleep with and within American Indian and Alaska Native communities.
Science Update: NIH-funded study finds no link between preconception COVID-19 vaccination and miscarriage risk
Among more than 1,800 women planning a pregnancy, those who received at least one dose of a COVID-19 vaccine before getting pregnant were no more likely to miscarry than those who were unvaccinated. The study also found no increased miscarriage risk among roughly 1,500 couples in which the male partner was vaccinated before trying to conceive.
Media Advisory: Umbilical cord milking appears to be safe in preterm infants born after 28 weeks
A treatment that moves 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, according to a study supported by NIH. Umbilical cord “milking”— gently squeezing the cord between the thumb and forefinger and pushing the blood into the newborn’s body—did not increase the risk of bleeding inside the brain for preterm infants born after 28 weeks of pregnancy.
Science Update: Maternal microbiome promotes placental development in mice, NIH-funded study suggests
Bacteria in the maternal digestive tract appear to stimulate blood vessel development of the placenta, suggests a mouse study. Studying the relationship between the mother’s microbiome and placental development may yield important insights into fetal and maternal health.
Director's Corner: Addressing the Tragedy of Stillbirth
Each year, more than 20,000 families in the United States experience a stillbirth, the loss of a fetus at 20 weeks or more of gestation. Stillbirth is a traumatic event that takes a devastating, lifelong psychological toll on families. October marks Pregnancy and Infant Loss Awareness Month, making this an opportune time to reflect on the work we must do to better understand the causes of—and ultimately prevent—these tragedies.
Science Update: NIH-funded study finds several potential risk factors for high blood pressure disorders of pregnancy in people with HIV
The risk for hypertensive disorders of pregnancy was higher for pregnant people with HIV if they had low CD4+ immune cell counts in the first or second trimester, or if they began taking antiretroviral drug regimens after 20 weeks of pregnancy, rather than at conception. The findings underscore the importance of getting HIV under control before becoming pregnant.
Science Update: MRI technique may predict impaired fetal growth and small size at birth, NIH-funded study suggests
A new imaging technique that measures the ability of the placenta to supply blood to the fetus may predict the chances of impaired fetal growth as early as the 14th week of pregnancy. The new method seems to allow earlier diagnosis than the standard ultrasound technique, which can detect reductions in placental blood flow at 20 to 24 weeks. Earlier detection of fetal growth restriction and risk of small for gestational age fetuses may lead to strategies for treating these conditions.
Director's Corner: Addressing the Health Effects of Climate Change
The effects of climate change on health are wide-ranging, from causing injuries and other medical concerns to disrupting vital supply chains. NICHD is committed to supporting scientific research to reduce climate-related health threats among its populations of interest—children, people of reproductive age, and people with intellectual and physical disabilities.
