Skin-to-skin care, or placing an infant on a caregiver’s bare chest for feeding or bonding, appeared to boost very preterm infants' neurodevelopment. Newborns cared for with the method had better neurodevelopment test scores at 12 months.

A report issued by the National Academies of Science, Engineering, and Medicine makes recommendations to improve the safe and ethical inclusion of pregnant and lactating women in clinical research while reducing the risk of liability. Enhancing inclusion of pregnant and lactating people in clinical research promises to help people and their health care providers make informed decisions.

Compared to formula fed infants, extremely preterm infants fed donated human milk had half the rate of necrotizing enterocolitis, a life threatening condition of the intestines. There were no differences in neurological development between those fed donor milk and those fed formula.

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

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.

Urea, present in breast milk but not digested by the infant, appears to foster the growth of beneficial bacteria in the infant gut, suggests a study funded by the National Institutes of Health. Urea is a nitrogen-containing waste product of protein digestion. In return for the breast milk-supplied urea, the bacteria provide the infant with essential nutrients. The results have important implications for the development of infant formula.

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.

The recent shortage of infant formula underscores its importance for the health of children in the United States, making this an opportune time for Dr. Bianchi to reflect on NICHD’s work to advance infant nutrition research.

Women who breastfed for two years or longer had higher blood levels of anti-Müllerian hormone and later onset of menopause, compared to women who breastfed for one month or less, according to an NICHD-supported analysis. The findings also suggest that previously observed relationships between menopause timing and the number of times a woman gave birth may be largely attributable to breastfeeding.

It just got easier to participate in the PregSource®: Crowdsourcing to Understand Pregnancy research project. The free app allows participants to track their weight, sleep, mood, and other features of their pregnancy in just a few taps.

As we usher in November and Thanksgiving, it’s a fitting time to reflect on NICHD’s commitment to research on nutrition.

No serious adverse events were reported by 180 breastfeeding women receiving either the Pfizer or Moderna vaccine, either among themselves or in their infants, according to a study funded by the National Institutes of Health. For the mothers, adverse events included muscle and body aches, fever and vomiting, pain, redness, swelling, or itching at the injection site.

Current vaccines to prevent COVID-19 are highly effective in producing antibodies in pregnant people, resulting in more antibodies than what is generated from a natural SARS-CoV-2 virus infection, according to a study funded by the National Institutes of Health. Moreover, antibodies produced after vaccination are present in breastmilk and travel across the placenta, indicating that vaccination during pregnancy will also confer immunity to newborns.

For many COVID-19 patients, full recovery remains elusive even long after they should feel “better.” NIH recently announced research opportunities to understand COVID-19 long haulers, who have what researchers now refer to as Post-acute sequelae of SARS-CoV-2 infection (PASC). NICHD joins these opportunities while remaining focused on PASC patients within our audiences of interest—pregnant and lactating people, children, and those with disabilities.

A new study funded by the National Institutes of Health will evaluate the effects of remdesivir in pregnant women who have been prescribed the drug to treat COVID-19. The study, which will be conducted at 17 sites in the continental United States and Puerto Rico, aims to determine how pregnant women metabolize the drug and whether there are any potential side effects.

Pregnant people need to be protected through research rather than from research, the authors contend.

As the COVID-19 pandemic persists, SARS-CoV-2 vaccines offer the potential to halt the spread of the virus. Yet, we know very little about the effectiveness and safety of the vaccines during pregnancy.
