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 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.

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.

Researchers have found the “Eat, Sleep, Console” (ESC) care approach to be more effective than using the Finnegan Neonatal Abstinence Scoring Tool (FNAST) to assess and manage opioid-exposed newborns, according to a national clinical trial funded by the National Institutes of Health.

Children with multisystem inflammatory syndrome (MIS-C)—a rare condition linked with the virus that causes COVID-19—have biochemical indicators of cell injury and cell death that are distinct from other children with COVID-19, according to a study funded by the National Institutes of Health.

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.

A research team including NICHD scientists has developed a potential gene therapy for hereditary spastic paraplegia 50, a rare childhood-onset neurodegenerative disorder that leads to developmental delays, cognitive impairment, and eventual paralysis.

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.

The National Institutes of Health is pleased to announce the winners of the STRIVE for Change: Drawing on Our Strengths Art Challenge, a prize competition for original artwork highlighting the strengths of communities experiencing health disparities. Two entries were selected to receive cash prizes.

Black people are about three times as likely as White people to die from a pregnancy-related cause, regardless of income or education level. The NIH-wide IMPROVE initiative works to reduce preventable pregnancy-related deaths and complications and promote health equity.

Compared to unvaccinated women, women vaccinated for COVID-19 have a slightly higher risk of a heavier period after vaccination, suggests a study funded by the National Institutes of Health. However, flow returns to normal in the next menstrual period.

The Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) has announced new funding for participating centers in its Neonatal Research Network (NRN). The purpose of the NRN is to improve healthcare and outcomes for newborns.

Placental cells secrete extracellular vesicles—tiny, balloon-like structures containing proteins, enzymes, DNA, and other molecules capable of transmitting chemical messages between cells—that appear to help regulate glucose uptake by maternal cells, according to a mouse study funded by the National Institutes of Health. In a series of experiments, the researchers found evidence that release of the vesicles follows placental release of the enzyme O-glycosyl transferase (OGT) after glucose levels rise. The findings may inform the development of new treatments for gestational (pregnancy-related) diabetes.
