There were more than 2.5 million cases of syphilis, gonorrhea, and chlamydia in the United States in 2022. NICHD research aims to prevent these and other sexually transmitted infections (STIs) among women, infants, children, and adolescents. Focus areas include addressing the need for additional STI prevention methods for women and curbing the rise in congenital syphilis cases.

Preterm infants born to people who have been vaccinated for COVID-19 had roughly the same levels of antibodies to the spike protein of SARS-CoV-2 as term infants born to vaccinated people, allaying concerns that fewer antibodies might pass to preterm infants.

Sepsis screening tools designed to account for the physiological changes that may occur during pregnancy perform best from 20 weeks of pregnancy through 3 days postpartum, research suggests. In early pregnancy and later in the postpartum period, tools based on general sepsis screening criteria may more accurately predict which patients are at high risk for maternal sepsis, a leading cause of pregnancy-related deaths.

An atlas of the placenta developed by NIH researchers offers insight on the communication that occurs between maternal and fetal cells during labor and delivery.

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.

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.

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.

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.

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.

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.

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.

Researchers developed a new method of evaluating blood from pregnant people to identify anomalies in the genes of fetuses. The new approach is more sensitive than current tests, which screen only for chromosome-level variants, such as an extra chromosome, and a small number of fetal genetic variants. It is also less invasive than current methods, which often involve inserting a needle into the uterus to retrieve fetal cells for analysis.

The Division of Intramural Research provides fundamental knowledge about the nature and behavior of living systems through basic, clinical, and population-based research.

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.

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

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.

For the first time, researchers were able to track development of the human placenta from the merging of placental cells with blood vessels in the uterus to a fully formed organ using new ultrasound technology that visualizes and measures blood flow through extremely small blood vessels. The images and data provide a reference for typical placental development to help with comparison studies, tracking, identification of placental disorders, and other complications.

Ableism—discrimination and social prejudice against those who are disabled—is a major contributor to the health disparities experienced by people with disabilities. Within NIH, NICHD has been at the forefront of efforts to address ableism in medicine and scientific research.

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.

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.
