Moms’ Microbes May Influence Babies’ Future Health

IRP Mouse Study Suggests Intervention Might Reduce Health Problems Associated with C-Section Births

Tuesday, October 15, 2024

Every kid’s first gift from their mom is half of her DNA, but nearly a third of children born nowadays miss out on a bonus present. That’s because babies born via vaginal delivery are exposed to the microorganisms that live in the vagina, but infants born via Cesarian section are not. A new IRP mouse study suggests that an intervention designed to make up for this missed opportunity could reduce the risk of certain health problems that are more common in babies born via C-section.

Postbac Poster Day Presents a Buffet of Biology

Young Scientists Demonstrate Fruits of Their IRP Research

Monday, May 20, 2024

There’s nothing quite like visiting NIH’s Postbac Poster Day to boost your faith that the future of biomedical science is bright. On May 1 and 2, more than a thousand recent college graduates participating in NIH’s Postbac program showed their colleagues, friends, and family the fascinating projects they’re working on in IRP labs. From delving into the aging brain to making sense of the bacteria on our skin, these aspiring researchers demonstrated that they have the passion needed to unravel the most complex mysteries of human biology. Read on to learn about the scientific questions just a few of them have been doggedly investigating over the past year.

Delivering on Maternal Health

IRP’s Katherine Grantz Develops Tools to Predict Pregnancy Complications

Tuesday, January 23, 2024

Advancements in medicine have reduced the risk of childbearing dramatically, but rates of maternal death have been creeping up in recent years. The reasons are varied. Older first-time parents, greater health concerns like obesity and hypertension, and lack of access to maternity care are important factors.

In observance of Maternal Health Awareness Day on January 23, we spoke with Katherine Grantz, M.D., a maternal-fetal medicine specialist and senior investigator at the Eunice Kennedy Shriver National Institute on Child Health and Human Development (NICHD). She is trying to improve health for pregnant people and their babies experiencing complications like gestational diabetes and hypertension, as well as reduce preterm deliveries and unnecessary C-sections.

Cooking Up a Recipe for Healthier Eating

IRP’s Tonja Nansel Probes the Hidden Forces Behind Our Food Choices

Monday, October 16, 2023

As legendary chef James Beard once said, “Food is our common ground, a universal experience.” Beyond a basic need to stay alive and obtain healthful nutrients, food is a source of pleasure, a reflection of culture, and a link to others. However, for many of us, food is also a challenge. There’s the food we love and the food that’s good for us, and the two aren’t always the same.

As we celebrate World Food Day on October 16, we spoke with IRP senior investigator Tonja Nansel, Ph.D., who is seeking explanations for the nutritional choices we make.

“The dietary quality of the U.S. population is well below recommended guidelines, and that’s the case regardless of income, education, and background,” Dr. Nansel says. “Simply put, we’re all eating badly.”

Moms’ Caffeine Consumption May Affect Babies’ Brains

Findings Could Explain Why Caffeine Exposure In-Utero Increases Kids’ Risk for Obesity

Between books, the media, and well-meaning friends and relatives, new parents are inundated with advice about how to set their kids up for a happy and healthy future. However, what parents do before their children are even born can also have a huge impact on how they turn out. For instance, new IRP research suggests that a pregnant woman’s caffeine consumption can rewire her baby’s brain in ways that put the child at increased risk for obesity later in life.

Research Helps Guide Families Safely Through Pandemic

IRP’s Diana Bianchi Honored for Leading Pediatric COVID Response

Monday, August 29, 2022

Dr. Diana Bianchi

When the first reports of COVID-19 came out, infectious disease experts and healthcare providers thought children might be spared its most dire effects. After all, the news reports and health statistics showed that nearly all serious cases occurred in the elderly, people with certain pre-existing conditions, and those who spent their days and nights caring for COVID patients. However, as case counts rose and disruptions in daily life grew, the medical and psychological effects of COVID on children became apparent — and the impact was alarming. It soon became clear that something had to be done to understand the disease's effects on infants, children and teens, as well as pregnant women and traditionally underserved communities.

It was, appropriately, Mother’s Day when then-NIH Director Francis Collins sought help from Diana W. Bianchi, M.D., Director of the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) and a senior investigator in the National Human Genome Research Institute (NHGRI). An expert in infant health and genetic conditions like Down syndrome, Dr. Bianchi was just the person to initiate large-scale studies across the country to assess the severity of COVID in specific populations, the safety and efficacy of vaccination and treatment, and the impact of mitigation efforts such as masking. For this critical leadership, Dr. Bianchi was named a finalist for the 2022 Samuel J. Heyman Service to America Medal for COVID-19 Response.

Researchers Delve Into New Moms’ Depression

Researchers Delve Into New Moms’ Depression

Tuesday, May 10, 2022

Fresh off celebrating Mother’s Day this past Sunday, as well as Women’s Health Week this week, it’s important to acknowledge that being a new mom isn’t easy. As joyful and exciting as a new baby might be, it can be exhausting and worrisome, too. Many new moms experience some level of baby blues, but for some women, those blues can take a downward turn into symptoms of more serious depression.

Approximately one out of every eight women in the U.S. experiences symptoms of postpartum depression, according to the U.S. Centers for Disease Control and Prevention. What’s more, a recent study led by IRP staff scientist Diane Putnick, Ph.D., has shown that the course of postpartum depression can differ significantly among women. The study of nearly 5,000 women not only showed that 25 percent of them experienced symptoms of postpartum depression, but it also found that depression symptoms followed several different patterns and could persist for at least three years after giving birth. Understanding these different patterns of symptoms and some of the risk factors associated with them may help physicians recognize and monitor mothers who are at higher risk for persistent depression.

Three-Minute Talks Pit Researchers Against the Clock

IRP Scientists Keep it Short and Sweet in Competition’s Final Round

Science is so closely associated with long, jargon-laden lectures that scientists like Neil deGrasse Tyson and the IRP’s own Anthony Fauci have become celebrities for their ability to explain complex scientific concepts in a succinct and understandable way. On June 25, 17 postbacs, graduate students, and postdocs from across NIH showcased their own communication chops in the final round of the IRP’s annual Three-Minute Talks (TmT) competition.

Rare Genetic Variants Underlie Susceptibility to Reproductive Disruption

IRP Study Could Help Identify Women at Greater Risk for Fertility Problems

Tuesday, February 2, 2021

As the calendar page turned from 2020 to 2021, many people adopted major lifestyle changes like healthier eating or significantly increasing their physical activity. While these New Year’s resolutions will likely improve their overall health, they could also wreak havoc on the reproductive cycles of a small set of women. New IRP research sheds light on the genetic factors that make some women susceptible to diet- or exercise-induced disruptions to their reproductive systems.

Blood Test Predicts Premature Labor

First-Trimester Blood Analysis Could Enable Earlier, More Effective Intervention

Tuesday, October 20, 2020

Imagine a world in which pregnant women routinely travel to places of healing and meet with wise sages who examine a bit of their blood to divine when their babies will be born. While this may sound like something out of Greek mythology, it may soon become a reality, as IRP researchers have developed a test that was able to use blood samples taken early in pregnancy to identify women who would later deliver their babies prematurely.
