Women who use marijuana could have a more difficult time conceiving a child than women who do not use marijuana, suggests a study by researchers at the National Institutes of Health.

For pregnant women with COVID-19 in the third trimester, antibodies against the SARS-CoV-2 virus appear to be transferred to the fetus at lower levels, compared to antibodies against two other respiratory diseases, suggests a study funded by the National Institutes of Health. However, one type of antibody against SARS-CoV-2 was transferred to the fetus more efficiently than the other antibodies against the virus, raising the possibility of at least some immune protection against the disease for the newborn.

Very low birthweight infants often need blood transfusions to survive. A National Institutes of Health-funded study suggests that providing a higher threshold of red cells within accepted limits offers no advantage in survival or reduction in neurological impairment over a lower threshold.

Medical care for newborn infants who were exposed to opioids in the womb varied widely across 30 hospitals nationwide, according to a study funded by the National Institutes of Health. The study authors say that the findings underscore the need for clinical trials to determine the most effective treatments.

Pregnant women who are infected with SARS-CoV-2, the virus that causes COVID-19, during the third trimester are unlikely to pass the infection to their newborns, suggests an NIH-funded study.

The National Institutes of Health has awarded eight research grants to develop approaches for identifying children at high risk for Multisystem Inflammatory Syndrome in Children (MIS-C), a rare and severe after-effect of COVID-19 or exposure to the virus that causes it. Up to $20 million will be provided for the projects over four years, pending the availability of funds.

Vegetarian diets during pregnancy are associated with small infant birth weight, but not a higher risk preterm birth or other medical complications, suggests a National Institutes of Health study.

Physicians could improve prescribing practices for children with severe neurological impairments by periodically administering parent questionnaires to assess the children’s symptoms, suggests a study funded by the National Institutes of Health. Such routine assessments could help detect adverse effects of drug interactions or cases in which medications have been under or overprescribed.

The National Center for Medical Rehabilitation was established in 1990 through the landmark Americans with Disabilities Act.

Women with asthma are more likely than normal to gain weight during pregnancy and to retain weight 3 months after giving birth, suggests a National Institutes of Health study. On average, women with asthma gained 3.1 kg (just under 7 lbs) more after a full-term pregnancy than women without asthma. Among women with asthma, weight gain was greater with obesity. Weight gain was also greater with more severe asthma and with asthma triggered by exercise. The study authors suggest that their findings underscore the importance of pre-pregnancy counseling for women with asthma on the need to achieve and maintain a healthy body weight.

Children with birth defects have a higher risk of cancer than children without birth defects. Now, researchers funded by the National Institutes of Health have found that children conceived through in vitro fertilization—who have a higher risk of birth defects than children conceived naturally—also have a commensurately higher risk of cancer than naturally conceived children with birth defects.

National Institutes of Health researchers have discovered a gene in mice that controls the craving for fatty and sugary foods and the desire to exercise. The gene, Prkar2a, is highly expressed in the habenula, a tiny brain region involved in responses to pain, stress, anxiety, sleep and reward. The findings could inform future research to prevent obesity and its accompanying risks for cardiovascular disease and diabetes.

Our National Center for Medical Rehabilitation Research has advanced the field with significant achievements over the past 30 years that have improved the health, independence and quality of life of people with disabilities.

National Institutes of Health study suggests women with mood disorders, gestatational diabetes may have a higher risk.

The plant compound apigenin improved the cognitive and memory deficits usually seen in a mouse model of Down syndrome, according to a study by researchers at the National Institutes of Health and other institutions. Apigenin is found in chamomile flowers, parsley, celery, peppermint and citrus fruits. The findings raise the possibility that a treatment to lessen the cognitive deficits seen in Down syndrome could one day be offered to pregnant women whose fetuses have been diagnosed with Down syndrome through prenatal testing.

Traces of genetic material from the placenta and other organs circulating in a pregnant woman’s blood stream could potentially be used to predict the risk for complications in later pregnancy, according to a new NICHD-supported study.

Researchers funded by the National Institutes of Health have used a rapid DNA sequencing technique to identify gene variants in roughly a third of cases of nonimmune Hydrops fetalis (NIHF), a serious condition in which a fetus develops fluid buildup inside the abdominal cavity, lungs, or other parts of the body. The findings suggest that the DNA sequencing technique, known as exome sequencing, could be used to provide information unavailable with current genetic testing methods.

NICHD has awarded nearly $2.5 million in grants to support research aimed at improving the understanding and prevention of firearm violence and mortality.

A National Institutes of Health study in mice suggests that parents have an innate capacity to respond to an infant’s cries for help and this capacity may serve as a foundation from which a parent learns to adjust to an infant’s changing needs.
