A magnetic resonance imaging (MRI) technique administered as early as the 14th week of pregnancy may predict the chances of impaired fetal growth. The technique measures the ability of the placenta to supply blood to the fetus. It appears to allow earlier diagnosis than the standard technique, ultrasound of the placenta, which can diagnose reductions in maternal blood flow to the placenta at 20 to 24 weeks. Earlier detection of fetal growth restriction and those at risk for being small for their gestational age at birth may lead to strategies for treating these conditions.

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.

The Eunice Kennedy Shriver National Institute of Child Health and Human Development has announced funding for research collaborations in its Global Network for Women’s and Children’s Health Research. The network, which is re-competed every seven years, consists of United States-based research centers and their counterparts in low- and lower middle-income countries. The Global Network began in 2001 and is dedicated to improving maternal and child health outcomes worldwide and building health research capacity in resource-poor settings.

Individuals with COVID-19 may experience a slight increase in menstrual cycle length, comparable to the menstrual cycle increase seen among those who received a COVID-19 vaccine, according to a study funded by the National Institutes of Health. The study authors stressed that the increase was small and temporary.

NIH has awarded $24 million in first-year funding to establish Maternal Health Research Centers of Excellence. The centers will develop and evaluate innovative approaches to reduce pregnancy-related complications and deaths and promote maternal health equity.

The gynecologic condition endometriosis has several differences in gene expression in the uterine lining, according to a comprehensive analysis of nearly 1,000 tissue samples by researchers funded in part by the National Institutes of Health. The differences stem from variations in DNA methylation—the binding of compounds known as methyl groups to DNA.

Infants born to mothers with sleep-disordered breathing—snoring, apnea, and other breathing difficulties during sleep—are more likely to develop complications such as jaundice, low blood sugar, seizures, or death during the newborn period, suggests a study funded by the National Institutes of Health. The authors called for studies to determine if treating mid-pregnancy, sleep-disordered breathing would improve infant outcomes.

Epigallocatechin gallate (EGCG), a compound found in green tea, appears to inhibit the biochemical processes that promote the growth and development of fibroid tumors cells, suggests a study funded in part by the National Institutes of Health. In laboratory tests of human fibroid cells, EGCG reduced the amount of a compound that promotes cell division and the quantity of proteins responsible for the tumors’ fibrous contents.

Strengthening our understanding of human milk biology and lactation is essential to support breastfeeding and to ensure the health of infants who do not have access to a lactating parent’s milk. NICHD supports a range of efforts to explore human milk as an active biological system and to promote the inclusion of pregnant and lactating people in clinical research.

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.

Depression from six weeks gestation through the end of pregnancy may increase the risk of heart and blood vessel disease up to two years after birth, suggests an analysis funded by the National Institutes of Health.

Tranilast, a drug used to treat allergies and certain types of scars, reduced the size of human fibroid tumors implanted in mice, according to an NIH-funded study. The authors said the results warranted additional studies in animals and perhaps in later human trials to evaluate this potential treatment for non-cancerous gynecologic tumors that can cause bleeding and pain and sometimes interfere with fertility.

A new guide developed by NICHD and its partners promises to standardize the exchange of clinical data on maternal and infant health. The guide is an important step toward establishing a common framework to help clinicians and scientists better understand the root causes and high rates of maternal morbidity and mortality.

NIH has announced the next round of winners of its Connecting the Community for Maternal Health Challenge—a $3 million prize competition to encourage community-based and advocacy organizations in the United States to develop the infrastructure and capabilities necessary to conduct maternal health research.

Premenopausal females who were vaccinated for COVID-19 were no more likely to report irregular menstrual cycles, heavier bleeds or menstrual pain than a similar group of unvaccinated women, according to a study funded by the National Institutes of Health. However, consistent with several previous studies, participants reported a small increase in cycle length of roughly one day following injection.

The health of pregnant individuals and new mothers in the nation’s prisons should be prioritized to avoid future public health crises from COVID-19, according to an analysis by NICHD-funded investigators. Recommended policy changes include early release, when possible, because pregnant people are at high risk from COVID-19, and prisons are not well-equipped to provide the necessary medical care. Moreover, prisons should promote COVID-19 vaccination and develop targeted messages for this population to counteract vaccine misinformation.

Infants born in 2020 through mid-2021 to women with COVID-19 weighed less at birth, but grew at a faster rate than a comparable group born to women who did not have COVID-19, according to a study funded by the National Institutes of Health. Previous studies have found that preterm infants and other infants who are small or underweight at birth and who undergo catch-up growth in the first year are at higher risk for later life obesity, heart disease, high blood pressure and diabetes, compared to infants born at normal weight. The authors called for additional studies of infants whose mothers had COVID-19 during pregnancy to learn if they have increased health risks later in life.

Tranexamic acid appears no more effective than placebo in reducing the need for blood transfusion or preventing maternal death in patients with increased risk for excessive bleeding because of cesarean delivery, according to a study funded by the National Institutes of Health. Tranexamic acid slows the natural breakdown of blood clots and was considered promising for reducing the risk of excessive bleeding after giving birth—known as postpartum hemorrhage—after cesarean delivery.

Dr. Veronica Gomez-Lobo, director of Pediatric and Adolescent Gynecology at NICHD, began her career as a clinician focused on caring for underserved populations. Taking advantage of interesting opportunities led her to become involved in medical education, and later, in scientific research.

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.
