NIH-funded technique enables automatic detection of placental compartments, oxygen status and structural abnormalities.

The National Institutes of Health is offering up to $8 million in cash prizes to accelerate development of technologies to improve maternal health outcomes for those who live in areas lacking access to maternity care.

Giving the hormone adiponectin to pregnant mice with obesity prevented later life obesity and related health conditions in their offspring, according to a study funded by the National Institutes of Health. The findings suggest that adiponectin, a hormone produced by fat cells, could play a role in reducing the lifelong obesity risk of children born to mothers with obesity during pregnancy.

The increase in pregnancy complications linked to air pollution exposure could result from the pollutants’ direct effects on the placenta, suggests a study in mice funded by the National Institutes of Health. Placentas of mice exposed to a mixture of common urban air pollutants before and during pregnancy were inflamed and had a loss of blood vessel cells. The study authors say the findings could provide insight into how air pollution might affect pregnancies and lead to strategies for preventing pregnancy complications.

The placenta supports pregnancy and influences the lifelong health of both mother and child. Yet it is the least understood, and least studied, of all human organs. In a guest post for the NIH Director’s Blog, Dr. Bianchi discusses work from NICHD’s Human Placenta Project to understand how the placenta functions in real time during pregnancy.

An individual’s risk for death by suicide may begin before they are born, suggests a study by researchers at the National Institutes of Health. The authors compared pregnancy and birth records of nearly 50,000 individuals born between 1959 and 1966 to death records through 2016. They found that suicide rates were higher for males, white people, and for those who were among the younger siblings in a family. Other risk factors included having a parent with less than a high school education, having a parent who worked a manual labor job, and having a mother with a high rate of pregnancy complications or who smoked during pregnancy.

Sleep-disordered breathing in early pregnancy is associated with insulin resistance or difficulty clearing glucose from the blood, suggests a small study funded by the National Institutes of Health. The results strengthen the link between sleep-disordered breathing, which includes pauses or slowing of breathing during sleep, and gestational diabetes. They also suggest that screening pregnant women, particularly those with overweight or obesity, for sleep-disordered breathing could identify those who might benefit from early interventions to reduce their diabetes risk.

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.

Awarded projects seek to reduce pregnancy complications and prevent maternal deaths.

Dr. Grewal has been acting director of the division since February 2020.

NIH-supported program reduces maternal deaths, complications in rural Guatemalan communities.

Pregnant women made only modest dietary changes after being diagnosed with gestational diabetes, according to a study by NICHD researchers.

NICHD Director Dr. Diana Bianchi is joined by NIH Office of Research on Women’s Health Director Dr. Janine Clayton in assessing the growing maternal health crisis in the United States and describing NIH’s efforts to address it.

Trophoblasts—the outermost fetal cells of the placenta—may be able to contain SARS-CoV-2 and prevent it from spreading to the fetus even though these cells appear to be susceptible to infection by the virus, a study by NIH-funded researchers suggests. Further research into how trophoblasts might contain the virus could lead to ways to prevent COVID-19 in children and adults. The findings may also lead to insights on why fetuses are only rarely infected with SARS-CoV-2.

A team of researchers funded by the National Institutes of Health has developed a new ultrasound technique to monitor the placenta for impaired fetal blood flow early in pregnancy. The technique, which uses conventional ultrasound equipment, relies on subtle differences in the pulsation of fetal blood through the arteries at the fetal and placental ends of the umbilical cord, potentially enabling physicians to identify placental abnormalities that impair fetal blood flow and, if necessary, deliver the fetus early.

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.
