Young adults born with HIV who report average or high levels of social support are more likely to maintain viral suppression than peers with low social support, according to a U.S. study funded by NIH. The findings also suggest that having sufficient social support is particularly important just prior to a young adult’s transition from pediatric to adult HIV care.

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.

With its longer days and warmer temperatures, summer is an ideal season for outdoor recreation. But fun activities like swimming also carry the risk of injuries, especially among children. NICHD supports a broad spectrum of research that seeks to prevent and treat pediatric injuries from drowning to dog bites.

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 previous study suggested that umbilical cord milking, a technique that moves blood from the umbilical cord into a newborn’s body, reduced the need for heart and respiratory support among infants classified as nonvigorous—limp, pale, and with minimal breathing—compared to the standard intervention, immediate cord clamping and cutting. A follow-up study supported by the National Institutes of Health indicates that the benefits of the technique may result from increased blood flow to the lungs and brain, along with an increase in blood pumped from the heart. The findings offer additional support for the use of umbilical cord milking in nonvigorous near term and term infants.

Delivery of the gene for neurotrophic factor-α1 directly into the hippocampus of the brain prevents neurodegeneration and memory loss in a mouse model of Alzheimer’s disease.

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.

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

A new smartphone app may improve early recognition of physical child abuse. By applying an evidence-based strategy developed with NICHD support, the app can help healthcare providers and social workers evaluate bruising on children younger than 4 years of age and identify cases that may need further investigation for child abuse.

Researchers funded in part by the National Institutes of Health have identified a second brain receptor abnormality in tissue from sudden infant death syndrome (SIDS) cases. Like the abnormality the group identified previously, the receptor binds to serotonin, a chemical that conveys messages between neurons. Although serotonin is involved in diverse functions such as mood, sleep, digestion, and wound healing, the abnormality the researchers identified is found in the medulla, or brain stem, a region involved in waking up, arousal, and breathing. The study authors believe the abnormalities underlie a vulnerability in the infant brain and may be responsible for an inability to wake up and take a breath under low oxygen conditions, such as when an infant’s mouth and nose are entrapped by bedding materials while sleeping face down.

For nearly four decades, NICHD’s Neonatal Research Network (NRN) has generated scientific evidence to improve the health of critically ill newborns. Recent findings from the NRN and collaborators mark an important step toward developing an evidence-based standard of care for newborns who were exposed to opioids during pregnancy.

A self-report tool developed with NICHD funding gathers feedback from lower-limb prosthesis wearers to better assess mobility challenges and inform treatment. Its use in clinical settings worldwide is changing the rehabilitation landscape and spurring the creation of similar tools for other audiences.

Among certain new fathers, the brain structure known as the hippocampus appears to grow larger from their partner’s pregnancy through to their child’s second year, suggests a study funded in part by the National Institutes of Health. Men who began the study with the largest hippocampal volume and had the greatest increases in hippocampal growth reported the greatest increase in feelings of attachment and bonding and lower stress levels regarding their new child.

The health of pregnant women 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 women 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.

A gel made from the seeds of a South American palm tree entraps SARS-CoV-2 and the protein the virus uses to enter cells, preventing the virus from infecting cells in laboratory cultures, a National Institutes of Health study has found. The findings raise the possibility of future studies to determine if the gel could be incorporated into masks and filters to reduce airborne spread of SARS-CoV-2.

Findings may aid design of targeted drug delivery into the brain and central nervous system.

Researchers funded by the National Institutes of Health have discovered a gene that could serve as a target for a new, non-hormonal contraceptive. The gene, arrestin domain containing 5 (ARRDC5) is present in several mammalian species and controls the last step in sperm maturation. Deactivating the gene results in lower sperm count and sperm with impaired movement that are incapable of fertilizing an egg—without any apparent ill effects elsewhere in the body.

Small businesses play a critical role in driving scientific progress by helping to move innovations out of labs and into the public marketplace. NICHD grants to small businesses have supported development of products ranging from the first FDA-approved endometriosis treatment to at-home rehabilitation devices.
