News
NICHD issues News Releases and Media Advisories to the news media. Spotlight and Research Feature articles explain NICHD research findings and public health issues to the general public. An Item of Interest is a short announcement of relevant information, such as a notable staff change.
Science Update: Placental particles in maternal bloodstream may signal less fetal growth, NIH-funded study suggests
Tiny, balloon-like particles released from the placenta could provide clues to identify fetuses at risk for growth restriction early so that pregnancies could be monitored for complications.
Director's Corner: Preventing Sexually Transmitted Infections
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.
Science Update: Preterm infants protected by maternal COVID-19 vaccination, NIH-funded study suggests
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.
Science Update: NIH-funded study suggests best ways to screen for sepsis during and after pregnancy
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.
Media Advisory: NIH-supported researchers create single-cell atlas of the placenta during term labor
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.
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.
Science Update: New method could replace conventional invasive procedures for prenatal testing, NIH-funded study suggests
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.
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.
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.
Science Update: NIH-funded researchers develop ultrasound library of placental development
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.
Director's Corner: Reducing Ableism in Medicine and Research
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.
