Pioneering research center aims to revolutionize prenatal and neonatal health

Catherine Limperopoulos, Ph.D., was drawn to understanding the developing brain, examining how early adverse environments for a mother can impact the baby at birth and extend throughout its entire lifetime. She has widened her lens – and expanded her team – to create the new Center for Prenatal, Neonatal & Maternal Health Research at Children’s National Hospital.

“Despite the obvious connection between mothers and babies, we know that conventional medicine often addresses the two beings separately. We want to change that,” said Dr. Limperopoulos, who also directs the Developing Brain Institute. “Given the current trajectory of medicine toward precision care and advanced imaging, we thought this was the right moment to channel our talent and resources into understanding this delicate and highly dynamic relationship.”

Moving the field forward

Since its establishment in July 2023, the new research center has gained recognition through high-impact scientific publications, featuring noteworthy studies exploring the early phases of human development.

Dr. Limperopoulos has been at the forefront of groundbreaking research, directing attention to the consequences of maternal stress on the unborn baby and the placenta. In addition, under the guidance of Kevin Cook, Ph.D., investigators published a pivotal study on the correlation between pain experienced by premature infants in the Neonatal Intensive Care Unit and the associated risks of autism and developmental delays.

Another area of research has focused on understanding the impact of congenital heart disease (CHD) on prenatal brain development, given the altered blood flow to the brain caused by these conditions during this period of rapid development. Led by Josepheen De Asis-Cruz, M.D., Ph.D., a research team uncovered variations in the functional connectivity of the brains of infants with CHD. In parallel, Nickie Andescavage, M.D., and her team employed advanced imaging techniques to identify potential biomarkers in infants with CHD, holding promise for guiding improved diagnostics and postnatal care. Separately, she is investigating the impact of COVID-19 on fetal brain development.

In the months ahead, the team plans to concentrate its efforts on these areas and several others, including the impact of infectious disease, social determinants of health and protecting developing brains from the negative impacts of maternal stress, pre-eclampsia and other conditions prevalent among expectant mothers.

Assembling a team

Given its robust research plan and opportunities for collaboration, the center pulled together expertise from across the hospital’s faculty and has attracted new talent from across the country, including several prominent faculty members:

  • Daniel Licht, M.D., has joined Children’s National to build a noninvasive optical device research group to better care for children with CHD. Dr. Licht brings decades of experience in pediatric neurology, psychiatry and critical care and is recognized internationally for his expertise in neurodevelopmental outcomes in babies with CHD.
  • Katherine L. Wisner, M.S., M.D., has accumulated extensive knowledge on the impact of maternal stress on babies throughout her career, and her deep background in psychiatry made her a natural addition to the center. While Dr. Wisner conducts research into the urgent need to prioritize maternal mental health, she will also be treating mothers as part of the DC Mother-Baby Wellness Initiative — a novel program based at Children’s National that allows mothers to more seamlessly get care for themselves and participate in mother-infant play groups timed to align with their clinical appointments.
  • Catherine J. Stoodley, B.S., M.S., D.Phil., brings extensive research into the role of the cerebellum in cognitive development. Dr. Stoodley uses clinical studies, neuroimaging, neuromodulation and behavioral testing to investigate the functional anatomy of the part of the brain responsible for cognition.
  • Katherine M. Ottolini, M.D., attending neonatologist, is developing NICU THRIVE – a research program studying the effects of tailored nutrition on the developing newborn brain, including the impact of fortifying human milk with protein, fat and carbohydrates. With a grant from the Gerber Foundation, Dr. Ottolini is working to understand how personalized fortification for high-risk babies could help them grow.

Early accolades

The new center brings together award-winning talent. This includes Yao Wu, Ph.D., who recently earned the American Heart Association’s Outstanding Research in Pediatric Cardiology award for her groundbreaking work in CHD, particularly for her research on the role of altered placental function and neurodevelopmental outcomes in toddlers with CHD. Dr. Wu became the third Children’s National faculty member to earn the distinction, joining an honor roll that includes Dr. Limperopoulos and David Wessel, M.D., executive vice president and chief medical officer.

Interim Chief Academic Officer Catherine Bollard, M.D., M.B.Ch.B., said the cross-disciplinary collaboration now underway at the new center has the potential to make a dramatic impact on the field of neonatology and early child development. “This group epitomizes the Team Science approach that we work tirelessly to foster at Children’s National,” Dr. Bollard said. “Given their energetic start, we know these scientists and physicians are poised to tackle some of the toughest questions in maternal-fetal medicine and beyond, which will improve outcomes for our most fragile patients.”

The Children’s National Hospital Zika Research Team and collaborators from Biomelab, in Barranquilla, Colombia take a picture after a study visit in Sabanalarga, Colombia following the neurodevelopmental outcomes of children who had in utero exposure to Zika virus. Pictured from Children’s National Hospital: Dr. Sarah Mulkey, Regan Andringa-Seed, Margarita Arroyave-Wessel, and Dr. Madison Berl.

The long-term neurodevelopmental effects of antenatal Zika virus (ZIKV) exposure in children without congenital Zika syndrome (CZS) remain unclear, as few children have been followed to the age of starting primary school.

In a new study published in Pathogens, researchers found children with in utero ZIKV exposure appear to have an overall positive developmental trajectory at 4 to 5 years of age but may experience risks to neurodevelopment in areas of emotional regulation and adaptive mobility.

The hold up in the field

Children who were born during the ZIKV epidemic and who had in utero exposure to ZIKV are only now at the age to start school. Child neurodevelopmental outcome data has not been reported at the age of school entry for children with antenatal ZIKV exposure who do not have the severe birth defects of CZS.

“As these children approach the early school-age years, we aim to examine whether there are neurodevelopmental differences in executive function, motor ability, language development or scholastic skills as compared to a group of unexposed control participants from the same communities in Colombia,” says Sarah Mulkey, M.D., Ph.D., prenatal-neonatal neurologist in The Zickler Family Prenatal Pediatrics Institute at Children’s National Hospital and lead author of the study.

Moving the field forward

Building on previous findings, this study presents the longitudinal outcomes of a well-characterized Colombian cohort of ZIKV-exposed children without CZS at ages 4 to 5 years. These children have been seen for neurodevelopmental follow-up as infants and toddlers at approximately 6 months, 18 months and 3 years of age as part of an international collaboration between researchers in Barranquilla, Colombia and at Children’s National beginning in 2016. The objective of this study was to assess the multi-domain neurodevelopmental outcomes in 4 to 5-year-old children with antenatal ZIKV exposure without CZS compared to unexposed controls in Colombia.

Why we’re excited

Many of the children who had antenatal ZIKV exposure are making good progress in multiple areas of their neurodevelopment. However, the researchers found that children with antenatal ZIKV exposure have differences in areas of emotional regulation, executive function, mood and behavior which may relate to virus exposure during their early brain development.

“These areas of brain function are important for future academic achievement, employment, mental health and social relationships,” says Dr. Mulkey. “So, it will be important to continue to follow these children at older ages when they start school.”

Children’s National leads the way

Children’s National is a leader in conducting outcome studies of children born following antenatal ZIKV exposure. This study follows children in Colombia who are now 5 years old who were first studied while they were in the womb. These children have contributed unique longitudinal understanding to early child neurodevelopment following in utero exposure to ZIKV.

Dr. Mulkey is committed to studying the long-term neurodevelopmental impacts that viruses like Zika and SARS-CoV-2 have on infants born to mothers who were infected during pregnancy through research with the Congenital Infection Program at Children’s National and in collaboration with colleagues in Colombia.

Additional Children’s National authors include Meagan Williams M.S.P.H., C.C.R.C., senior research coordinator; Regan Andringa-Seed, clinical research coordinator, Margarita Arroyave-Wessel, clinical research coordinator; L. Gilbert Vezina, M.D., director, Neuroradiology Program; Dorothy Bulas, M.D., chief, Diagnostic Imaging and Radiology; Robert Podolsky, biostatistician.

Prenatal COVID exposure associated with changes in newborn brain

pregnant woman talking to doctor

The team found differences in the brains of both infants whose mothers were infected with COVID while pregnant, as well as those born to mothers who did not test positive for the virus.

Babies born during the COVID-19 pandemic have differences in the size of certain structures in the brain, compared to infants born before the pandemic, according to a new study led by researchers at Children’s National Hospital.

The team found differences in the brains of both infants whose mothers were infected with COVID while pregnant, as well as those born to mothers who did not test positive for the virus, according to the study published in Cerebral Cortex.

The findings suggest that exposure to the coronavirus and being pregnant during the pandemic could play a role in shaping infant brain development, said Nickie Andescavage, M.D., the first author of the paper and associate chief for the Developing Brain Institute at Children’s National.

The fine print

The study’s authors looked at three groups of infants: 108 born before the pandemic; 47 exposed to COVID before birth; and 55 unexposed infants. In all cases, researchers performed magnetic resonance imaging (MRI) scans of the newborns’ brains during the first few weeks of life. The MRI scans, which are non-invasive and do not expose patients to radiation, provided 3D images of the brain, allowing doctors to calculate the volume of different areas.

Researchers found several differences in the brains of babies exposed to COVID. They had larger volumes of the gray matter that makes up the brain’s outermost layer, compared to the two other groups. In contrast, an inner area of the brain, known as deep gray matter, was smaller than in unexposed babies. These are areas that contain large numbers of neurons that generate and process signals throughout the brain. “Their brains formed differently if they were exposed to COVID,” said Dr. Andescavage, adding that “those exposed to COVID had unique signatures” in the brain.

Doctors also measured the depths of the folds in the babies’ brains – a way to determine how the brain is maturing during early development. Babies born to mothers who had COVID in pregnancy had deeper grooves in the frontal lobe, while babies born during the pandemic – even without being exposed to COVID – had increased folds and grooves throughout the brain, compared to babies born before the pandemic. “There was something about being born during the pandemic that changed how the brain developed,” Dr. Andescavage said.

What’s ahead

The study authors can’t fully explain what caused the differences in brain development in these babies, Dr. Andescavage said. But other studies have linked maternal stress and depression to changes in the newborn brain. In a future study, Dr. Andescavage and her colleagues will examine the relationship between infant brain development and how stress and anxiety during the pandemic may have played a role in early development.

Because the babies in the study were just a few weeks old, researchers don’t know if their altered brain development will affect how they learn or behave. Researchers plan to follow the children until age 6, allowing them to observe whether pandemic-era babies hit key developmental milestones on time, such as walking, talking, holding a crayon and learning the alphabet.

Researchers have been worried about the effect of COVID on the fetus since the beginning of the pandemic. Studies show that babies exposed to COVID in the womb may experience developmental impacts, and research is underway to better understand long-term outcomes.

Although the coronavirus rarely crosses the placenta to infect the fetus directly, there are other ways maternal infection can influence the developing baby. Dr. Andescavage said inflammation is one potential harm to a developing baby. In addition, if a pregnant woman becomes so sick that the levels of oxygen in her blood fall significantly, that can deprive the fetus of oxygen, she added.

In recent decades, studies of large populations have found that maternal infections with influenza and other viruses increased the risk of serious problems in children even years later, including autism, attention deficit hyperactivity disorder and schizophrenia, although the reasons behind the association are not well understood. Technology may allow doctors to answer a number of questions about COVID and the infant brain.

“With advanced imaging and MRI, we’re in a position now to be able to understand how the babies are developing in ways we never previously could,” Dr. Andescavage said. “That will better allow us to identify the exposures that may be harmful, and at what times babies may be especially vulnerable, to better position us to promote maternal wellness. This, in turn, helps infant wellness.”

Evidence review: Maternal mental conditions drive climbing death rate in U.S.

mother kissing newborn baby

More than 80% of maternal deaths in the United States are preventable, particularly the nearly 1 in 4 maternal fatalities that are attributable to mental health disorders.

Painting a sobering picture, a research team led by Children’s National Hospital culled years of data demonstrating that maternal mental illness is an under-recognized contributor to the death of new mothers. They are calling for urgent action to address this public health crisis in the latest edition of JAMA Psychiatry.

Backed by dozens of peer-reviewed studies and health policy sources, the journal’s special communication comes as maternal mortality soars in the United States to as much as three times the rate of other high-income countries.

“The contribution of mental health conditions to the maternal morbidity and mortality crisis that we have in America is not widely recognized,” said Katherine L. Wisner, M.D., associate chief of Perinatal Mental Health and member of the Center for Prenatal, Neonatal & Maternal Health Research at Children’s National. “We need to bring this to the attention of the public and policymakers to demand action to address the mental health crisis that is contributing to the demise of mothers in America.”

The evidence review laid out the risks facing new mothers: More than 80% of maternal deaths in the United States are preventable, particularly the nearly 1 in 4 maternal fatalities that are attributable to mental health disorders. Overdose and other maternal mental health conditions are taking the lives of more than twice as many women as postpartum hemorrhage, the second leading cause of maternal death. For non-Hispanic Black mothers, the mortality rate is a striking 2.6 times higher than non-Hispanic White mothers.

Yet the research team found that recent national efforts to combat maternal mortality have failed to address maternal mental health as “the public health crisis that it represents.” Even methodologies to measure maternal health statistics are inconsistent, which challenges efforts to shape health policy.

In examining 30 recent studies and another 15 historical references, the team – which included Caitlin Murphy, MPA, PNP, research scientist at the Milken School of Public Health at George Washington University, and Megan Thomas, M.D., FACOG, obstetrician at the University of Kansas School of Medicine – found ample data to support the need to elevate maternal mental health as a priority. Some examples:

  • Multiple studies show that the perinatal period puts women at higher risk for new and recurrent psychiatric disorders, with 14.5% of pregnant mothers having a new episode of depression and another 14.5% developing an episode three months after birth.
  • Nationwide, more than 400 maternity healthcare centers closed between 2006 and 2020, creating “maternity care deserts” that left nearly 6 million women with limited or no access to maternity care.
  • Mental health conditions such as suicide or opioid overdose are to blame for nearly 23% of maternal deaths in America, according to reports from three dozen Maternal Morbidity and Mortality Review Committees, which are state-based organizations that review each maternal death within a year of pregnancy. That’s followed by hemorrhage (13.7%), cardiac conditions (12.8%) and infection (9.2%).

Even with these sobering statistics, Dr. Wisner says that only 20 percent of women are screened for depression postpartum. “Given that this is a time that many mothers have contact with healthcare professionals, it’s critically important that all mothers are screened and offered treatment,” she said. “Mental health is fundamental to health — of the mother, the child and the entire family.”

Dr. Wisner is board-certified in general and child psychiatry. Throughout her research career, she has conducted research on maternal-infant interactions and family health. She recently joined the new Center for Prenatal, Neonatal & Maternal Health Research because of its vision to improve outcomes for the entire family by understanding the relationship between mothers and their babies.

“Throughout my career, I have fought hard against these silos that try to lock psychiatry into certain age categories,” Dr. Wisner said. “At Children’s National, we have a huge interest in reunifying the family. We want to ensure that we’re caring for unborn babies, infants and toddlers, while focusing on maternal health and the family in its broader context.”

AHA’s Outstanding Research Award: Three generations of pediatric cardiac excellence

Drs. Catherine Limperopoulos, Yao Wu and David Wessel

Catherine Limperopoulos, Ph.D., Yao Wu, Ph.D., and David Wessel, M.D.

Children’s National Hospital is celebrating a remarkable milestone as three of its faculty members have been honored over 15 years with the American Heart Association’s Outstanding Research in Pediatric Cardiology Award. Yao Wu, Ph.D., became the latest researcher to earn the accolade for her groundbreaking work into congenital heart disease (CHD).

A research faculty member with the newly established Center for Prenatal, Neonatal & Maternal Health Research, Dr. Wu received the award specifically for her studies on the role of altered placental function, measured by advanced in utero imaging, and neurodevelopmental outcomes in toddlers with CHD.

Honored at the association’s annual meeting in Philadelphia, Dr. Wu returned to Children’s National to warm congratulations from her colleagues who had previously won the award: David Wessel, M.D., executive vice president and chief medical officer, and Catherine Limperopoulos, Ph.D., director of the new center.

“I am thrilled to pass the baton to one of our own,” Dr. Limperopoulos said. “Dr. Wu’s recognition speaks to the outstanding and innovative research happening at Children’s National among junior faculty who are focusing on advancing our understanding of congenital heart disease and its long-term neurodevelopmental outcomes.”

Why we’re excited

The prestigious award represents more than individual accomplishments; it symbolizes three generations of mentorship and collaboration at the hospital. In 2007, Dr. Wessel joined Children’s National to enhance the care of newborns across specialty services by expanding programs and research, with a focus on critically ill newborns with heart disease. He recruited and mentored Dr. Limperopoulos in 2010, who became one of his research partners and creator of the hospital’s Center for Prenatal, Neonatal & Maternal Health Research. Dr. Limperopoulos, in turn, recruited and mentored Dr. Wu, providing her with the tools to conduct advanced imaging on in-utero brains and placentas, as well as the development of children with CHD.

“Each one of us is in different phases of our careers, yet we are connected by our deep interest in advancing cardiac care for critically ill newborns,” Dr. Wessel said. “In this collaborative environment, we learn from each other to improve entire lifetimes for our patients.”

Dr. Wu said she believes in sharing scientific developments for the advancement of the entire medical community. “It was an honor to be chosen to join this esteemed club, which has a relentless focus on improving health outcomes,” she said.

Children’s National leads the way

The award winners shared five collaborations published in leading journals to contribute to the ongoing dialogue in the field and the innovative work happening at Children’s National:

Understanding mechanisms of injury due to prematurity in human cerebellum

Dr. Panagiotis Kratimenos in the lab

“There is no better model to study preterm injury than the human brain. Our team, along with the expertise of the scientific advisory board of the Raynor Cerebellum Project, will approach this project in multiple ways to extract the most possible information from the extremely precious human tissues,” says Dr. Kratimenos.

Children’s National Hospital has received $1 million in funding as part of the Raynor Cerebellum Project, whose mission is to improve the lives of those with cerebellar disease in seven to ten years. Panagiotis Kratimenos, M.D., Ph.D., principal investigator and Co-Director of Research in the Division of Neonatology at Children’s National, says the goal of this work is to understand the mechanisms of injury due to prematurity in human cerebellum and identify opportunities for intervention.

Why the research is unique

This project is unique because it focuses on postmortem human cerebellum, addressing the effect of the immune dysregulation of the mother during preterm labor. “We have established a large cohort of human term and preterm subjects and we will leverage cutting edge techniques to understand how the immune system of the mother during preterm labor shapes the cerebellum in a way that becomes more vulnerable to subsequent insults,” says Dr. Kratimenos.

Why this research matters for critical newborns

“There is no better model to study preterm injury than the human brain. Our team, along with the expertise of the scientific advisory board of the Raynor Cerebellum Project, will approach this project in multiple ways to extract the most possible information from the extremely precious human tissues. This will give us insight into the real mechanisms of preterm birth induced injury due to maternal immune dysregulation,” says Dr. Kratimenos.

Babies with congenital heart disease display disrupted brain function before birth

pregnant woman looking at sonogram

In their study, the team at Children’s National Hospital found that specific brain regions become especially vulnerable to injury around 24 weeks of pregnancy when developing babies begin to have high energy demands and rapid neurovascular changes.

For the first time, researchers have found that babies born with congenital heart disease (CHD) have alterations to the emerging functional connectivity of their brains in utero. The changes are related to the subtype of their CHD and their oxygen status before they have lifesaving surgery to treat their cardiac malformation, according to new findings published in the American Heart Association’s Circulation Research.

In their study, the team at Children’s National Hospital found that specific brain regions become especially vulnerable to injury around 24 weeks of pregnancy when developing babies begin to have high energy demands and rapid neurovascular changes. That leaves certain parts of the brain, including the brainstem, more susceptible to injury from cardiac complications and poor circulation.

“We used a special type of magnetic resonance imaging to safely study the brains of these unborn babies, and we found that they have weakened connectivity in the deep grey structures, which are responsible for sensation, movement, alertness and other core functions,” said Josepheen De Asis-Cruz, M.D., Ph.D., assistant professor at the Developing Brain Institute at Children’s National and an author of the study. “This offers an important clue in utero to the type of care the babies will eventually need when they are born.”

The big picture

In the past decade, the survival rate for fetuses with CHD has greatly improved. About 80% of cases – even some of the most high-risk heart defects – can be successfully treated or palliated with surgery and survive. Yet Dr. Cruz said researchers are finding that the rates of poor neurodevelopmental outcomes are about the same. That’s why she and her colleagues are looking at what precisely may be injuring the brains of these newborns prior to surgery, offering a possible roadmap to interventions.

The fine print

The research team studied 107 healthy, low-risk pregnancies and 75 pregnancies known to be complicated by CHD. They used functional connectivity magnetic resonance imaging (fcMRI) to examine the emerging connections of the brains of unborn babies, given fcMRI’s unique ability to query the brain in a resting state when a patient is unable to respond to tasks. They also studied the oxygen saturation levels of the babies after they were born and then mapped all of this information to the type of CHD that they were diagnosed with.

“Our findings indicate that the compromised connectivity in the brains of CHD patients before delivery is linked to hypoxia after birth,” Cruz said. “There were important differences in the low- and high-risk CHD groups. Babies born with transposition of the great arteries or hypoplastic left heart syndrome – two of the most high-risk diagnoses – have notable changes in their brain function, which could someday be used as biomarkers to guide their care.”

What’s ahead

Researchers at Children’s National are working together, using a variety of modalities, to move toward precision imaging in utero to help predict a child’s neurodevelopmental outcomes. The ultimate goal: better interventions sooner.

“This work is foundational. As we fine-tune more techniques to identify babies at risk, we can understand how environmental, genetic and epigenetic factors impact brain development and guide care decisions,” said Catherine Limperopoulos, Ph.D., director of the Center for Prenatal, Neonatal & Maternal Health Research and a senior author of the paper. “We can imagine a day where we can offer pregnant mothers highly detailed and personalized information about their unborn baby, and individualized interventions that lead to healthier lifetimes.”

Imaging reveals altered brain chemistry of babies with CHD

Researchers at Children’s National Hospital used magnetic resonance spectroscopy to find new biomarkers that reveal how congenital heart disease (CHD) changes an unborn baby’s brain chemistry, providing early clues that could someday guide treatment decisions for babies facing lifelong health challenges.

Published in the Journal of the American College of Cardiology, the findings detail the ways that heart defects disrupt metabolic processes in the developing brain, especially during the third trimester of pregnancy when babies grow exponentially.

“Over the past decade, our team has been at the forefront of developing safe and sophisticated ways to measure and monitor fetal brain health in the womb,” said Catherine Limperopoulos, Ph.D., director of the Center for Prenatal, Neonatal and Maternal Health Research at Children’s National. “By tapping into the power of advanced imaging, we were able to measure certain maturational components of the brain to find early biomarkers for newborns who are going to struggle immediately after birth.”

The fine print

In one of the largest cohorts of CHD patients assembled to date, researchers at Children’s National studied the developing brains of 221 healthy unborn babies and 112 with CHD using magnetic resonance spectroscopy, a noninvasive diagnostic test that can examine chemical changes in the brain. They found:

  • Those with CHD had higher levels of choline and lower levels of N-Acetyl aspartate-to-choline ratios compared to healthy babies, potentially representing disrupted brain development.
  • Babies with more complex CHD also had higher levels of cerebral lactate compared to babies with two ventricle CHD. Lactate, in particular, is a worrying signal of oxygen deprivation.

Specifically, elevated lactate levels were notably increased in babies with two types of heart defects: transposition of the great arteries, a birth defect in which the two main arteries carrying blood from the heart are switched in position, and single ventricle CHD, a birth defect causing one chamber to be smaller, underdeveloped or missing a valve. These critical heart defects generally require babies to undergo heart surgery not long after birth. The elevated lactate levels also were associated with an increased risk of death, highlighting the urgency needed for timely and effective interventions.

The research suggests that this type of imaging can provide a roadmap for further investigation and hope that medicine will someday be able to better plan for the care of these children immediately after their delivery. “With important clues about how a fetus is growing and developing, we can provide better care to help these children not only survive, but thrive, in the newborn period and beyond,” said Nickie Andescavage, M.D., Children’s National neonatologist and first author on the paper.

The big picture

CHD is the most common birth defect in the United States, affecting about 1% of all children born or roughly 40,000 babies each year. While these defects can be fatal, babies who survive are known to be at significantly higher risk of lifelong neurological deficits, including lower cognitive function, poor social interaction, inattention and impulsivity. The impact can also be felt in other organ systems because their hearts did not pump blood efficiently to support development.

Yet researchers are only beginning to pinpoint the biomarkers that can provide information about which babies are going to struggle most and require higher levels of care. The National Institutes of Health (NIH) and the District of Columbia Intellectual and Developmental Disabilities Research Center supported the research at Children’s National to improve this understanding.

“For many years we have known that the brains of children with severe heart problems do not always develop normally, but new research shows that abnormal function occurs already in the fetus,” said Kathleen N. Fenton, M.D., M.S., chief of the Advanced Technologies and Surgery Branch in the Division of Cardiovascular Sciences at the National Heart, Lung, and Blood Institute (NHLBI). “Understanding how the development and function of the brain is already different before a baby with a heart defect is born will help us to intervene with personal treatment as early as possible, perhaps even prenatally, and improve outcomes.”

Survey: Teen parents with support report greater well-being

smiling young family

Teen parents in Washington, D.C., reported better physical and mental health when they had more social support, a community and people who understood their problems.

Teen parents in Washington, D.C., reported better physical and mental health when they had more social support, a community and people who understood their problems, according to a survey conducted as part of a novel city-wide program to bring together resources for young families.

“This should come as no surprise. Young parents say they do better – and their children do better – when they have the material and social supports they need,” said Yael Smiley, M.D., a pediatrician at Children’s National Hospital and lead author of research in BMC Public Health. “This work is the start of a roadmap to help young parents thrive.”

The big picture

Each year in D.C., 300 babies are born to teens, and the rate of births among teens ages 15 to 17 is higher than the national average. Dr. Smiley is a leader in a federally funded coalition run by D.C. Primary Care Association (DCPCA) to help support young parents called the D.C. Network for Expectant and Parenting Teens (DC NEXT!). This city-wide network brings together community partners to support teen mothers, fathers and their children.

A key feature of the program is its context team, a group of teen parents who provide insights into their experiences as young parents. They advise about research and support for their peers, and they also build a community and develop a platform to speak up about their issues. The context team recruited other parents to complete a well-being survey in 2022, which will guide programming and resources for families. An added benefit for the parents who participate in the context team: The survey data showed that a key facet of well-being for the young parents was feeling “like you were part of a group of friends or community” and having “someone who understood your problems.”

“The context team provides the type of community that the research shows is essential to the well-being of teen parents,” said Dr. Smiley. “Not only are the context team members helping us understand what teen parents need, but they are also helping each other thrive as young parents.”

The fine print

Among the findings of the survey of 107 teen parents in D.C.:

  • The most used resources were supplemental food programs – with 35% receiving Supplemental Nutrition Assistance Program (SNAP) benefits, 24% receiving support from the Special Supplemental Nutrition Program for Women, Infants and Children (WIC) and 18% accessing food pantries.
  • Also popular were Temporary Assistance for Needy Families (TANF), housing assistance and childcare.
  • Surprisingly, the largest group of respondents, 37%, reported receiving no resources.

Having higher social support was correlated with higher ratings for physical health, mental health and well-being. “With this research, we have even more evidence underscoring the need to connect young parents with programs and resources that will improve their well-being,” Smiley said. “I can’t wait to see what the leaders on the context team and in the DC NEXT! program do in the next phases of our work.”

Lenore Jarvis, M.D. participates in congressional briefing on maternal mental health

Lenore Jarvis, M.D., M.Ed., recently participated in a congressional briefing about maternal mental health.



Lenore Jarvis, M.D., M.Ed., director of advocacy and health policy for the Division of Emergency Medicine and an affiliate faculty member of the Child Health Advocacy Institute at Children’s National Hospital, recently participated in a congressional briefing about maternal mental health. The goal of the briefing was to bring awareness to the devastating impact of untreated perinatal mood and anxiety disorders (PMADs) on moms, babies and families and to eliminate the pervasive stigma around seeking care, including in communities of color and military populations.

PMADs are one of the leading causes of maternal mortality and morbidity in the U.S., responsible for nearly one quarter of all maternal deaths. Evidence shows that 1 in 5 women experience a PMAD during pregnancy or the postpartum period. All maternal mental health conditions are treatable, yet over 75% go untreated.

Dr. Jarvis spoke about the importance of screening caregivers for PMADs not just in outpatient settings, but also in emergency departments and NICUs. She said that an emergency department can serve as a safety net for high-risk patient populations who may have limited access to primary or mental health care, or for those who use the emergency department at a time of increased stress, anxiety or depression. Similarly, the NICU population is comprised of caregivers coping with stressful scenarios like traumatic perinatal or birth experiences and life altering diagnoses.

“At Children’s National, our primary care clinics screen for PMADs, but we also provide universal screening by approaching caregivers with infants six months and younger in both the emergency department and the NICU. Our philosophy is that by offering this screening and education to families, we are providing a higher standard of care for the patients seen in these settings,” said Dr. Jarvis. If a caregiver screens positive, meaning they are exhibiting enough symptoms that they could be at risk for experiencing PMADs, a member of our social work team meets with that caregiver to complete an additional assessment and provide further support, including to understand if there are suicidal or infanticidal ideations and intent to act. Our social workers can then make referrals to connect them to more care and follow up with those caregivers to confirm they have connected with the appropriate resource.

Dr. Jarvis was asked how to make it easier to support caregivers and families regarding PMADs. “Caregivers need education regarding PMADs. We need them to know it’s common and it doesn’t make them bad parents. We also need to ensure that providers are screening and that they have increased time for visits that include addressing mental health concerns.” She also stressed that the healthcare system can be difficult to navigate. “We need to decrease barriers to care, like the long wait times to get into mental health care and insurance coverage issues.”

U.S. News Badges

Children’s National Hospital ranked #5 in the nation on U.S. News & World Report’s Best Children’s Hospitals Honor Roll

U.S. News BadgesChildren’s National Hospital in Washington, D.C., was ranked #5 in the nation on the U.S. News & World Report 2023-24 Best Children’s Hospitals annual rankings. This marks the seventh straight year Children’s National has made the Honor Roll list. The Honor Roll is a distinction awarded to only 10 children’s hospitals nationwide.

For the thirteenth straight year, Children’s National also ranked in all 10 specialty services, with eight specialties ranked in the top 10 nationally. In addition, the hospital was ranked best in the Mid-Atlantic for neonatology, cancer, neurology and neurosurgery.

“Even from a team that is now a fixture on the list of the very best children’s hospitals in the nation, these results are phenomenal,” said Kurt Newman, M.D., president and chief executive officer of Children’s National. “It takes a ton of dedication and sacrifice to provide the best care anywhere and I could not be prouder of the team. Their commitment to excellence is in their DNA and will continue long after I retire as CEO later this month.”

“Congratulations to the entire Children’s National team on these truly incredible results. They leave me further humbled by the opportunity to lead this exceptional organization and contribute to its continued success,” said Michelle Riley-Brown, MHA, FACHE, who becomes the new president and CEO of Children’s National on July 1. “I am deeply committed to fostering a culture of collaboration, empowering our talented teams and charting a bold path forward to provide best in class pediatric care. Our focus will always remain on the kids.”

“I am incredibly proud of Kurt and the entire team. These rankings help families know that when they come to Children’s National, they’re receiving the best care available in the country,” said Horacio Rozanski, chair of the board of directors of Children’s National. “I’m confident that the organization’s next leader, Michelle Riley-Brown, will continue to ensure Children’s National is always a destination for excellent care.”

The annual rankings are the most comprehensive source of quality-related information on U.S. pediatric hospitals and recognizes the nation’s top 50 pediatric hospitals based on a scoring system developed by U.S. News.

“For 17 years, U.S. News has provided information to help parents of sick children and their doctors find the best children’s hospital to treat their illness or condition,” said Ben Harder, chief of health analysis and managing editor at U.S. News. “Children’s hospitals that are on the Honor Roll transcend in providing exceptional specialized care.”

The bulk of the score for each specialty service is based on quality and outcomes data. The process includes a survey of relevant specialists across the country, who are asked to list hospitals they believe provide the best care for patients with the most complex conditions.

The eight Children’s National specialty services that U.S. News ranked in the top 10 nationally are:

The other two specialties ranked among the top 50 were cardiology and heart surgery, and urology.

Community-wide program to support teen parents serves as a model for engagement

More than 500 adolescent mothers, caregivers and community members benefitted from a coordinated “collective impact” model to provide support aimed at addressing the litany of strains faced by teen parents, according to a case study published Wednesday in the journal Pediatrics.

Known as the District of Columbia Network for Parenting and Expectant Teens (DC NEXT), the model used well-tested pillars of community organization to provide services and care that bolstered the well-being of pregnant and expectant teens in the city. The case study found that the 3-year-old program, which included teen advisors to help guide the mission, could serve as a model in other areas with high rates of teen parents.

“There’s no system of care for teen parents in Washington, D.C., or really anywhere in our country,” said Yael Smiley, M.D., Children’s National Hospital pediatrician and the study’s lead author. “Our coalition came together to connect the resources and the people who care about young parents and their families to improve their health, their outcomes, their well-being, and set them up for success. We fuse representatives from healthcare, education and housing policy — people who care about creating the very best outcomes possible.”

The patient benefit

More than 140,000 teens became parents in 2021 in the United States. In Washington, D.C., more than 300 babies are born to teens each year, and the rate of births to young teens ages 15 to 17 is double the national average. These young parents often face barriers to childcare and education and poor birth outcomes, often stemming from a lack of access to prenatal care.

To address these obstacles, the network assembled a city-wide network in 2020 to follow the five pillars of an evidence-based “collective impact” model:

  • Create a common agenda
  • Design shared measurement systems
  • Host mutually reinforcing activities
  • Foster continuous communication
  • Rely on trusted backbone support

What’s unique

DC NEXT was housed at the District of Columbia Primary Care Association (DCPCA), which received the 3-year, $4.5 million federal grant and provided the leadership. At Children’s National, Dr. Smiley led a team that partnered with DCPCA and Howard University to direct a network of community clinics, nonprofits and other organizations whose mission was to support adolescent parents. Hundreds of client-facing staff members were trained to provide trauma-informed, human-centered care. DC NEXT also engaged directly with teen mothers through well-being surveys that led to improved access to essential programs, including resources for housing and food security. Over 550 young parents and caregivers have been impacted by the program.

The leadership quickly realized that the teen parents needed a voice and created a “context team” of paid teen advisors who provided insights into their unique experiences and needs as parents. They help set the agenda, choose program offerings and tailor communications to their peers.

“If the network can continue to grow and support young parents to achieve their health and well-being goals, the impact will be felt across generations,” said Dr. Smiley.

Pandemic stress reshapes the placentas of expectant moms

stressed pregnant mom

Elevated maternal stress during the COVID-19 pandemic changed the structure, texture and other qualities of the placenta in pregnant mothers.

Elevated maternal stress during the COVID-19 pandemic changed the structure, texture and other qualities of the placenta in pregnant mothers – a critical connection between mothers and their unborn babies – according to new research from the Developing Brain Institute at Children’s National Hospital.

Published in Scientific Reports, the findings spotlight the underappreciated link between the mental health of pregnant mothers and the health of the placenta – a critical organ that develops during pregnancy to nourish and protect babies. The long-term neurodevelopmental impact on their children is under investigation.

“During the pandemic, mothers were exposed to a litany of negative stressors including social distancing, fear of dying, financial insecurity and more,” said Catherine Limperopoulos, Ph.D., chief and director of the Developing Brain Institute, which led the research. “We now know that this vital organ was changed for many mothers, and it’s essential that we continue to investigate the impact this may have had on children who were born during this global public health crisis.”

The big picture

Dr. Limperopoulos’s team compared magnetic resonance imaging (MRI) of 165 women who were pregnant before March 2020 to 63 women who became pregnant during the pandemic. Those pregnant during the pandemic were not knowingly exposed to COVID-19, and they collectively scored significantly higher on questionnaires measuring stress and depression. They were recruited at Children’s National as part of a clinical trial aimed at reducing pregnant women’s elevated stress levels during the pandemic.

The placenta is a temporary organ that grows during pregnancy to provide oxygen, nutrients and immunological protection to babies, and its health is vital to the well-being of the developing fetus. The data showed key changes in how the placenta grew and developed among women pregnant during the pandemic, especially when compared to placental growth and development among women who were pregnant before the pandemic. Changes in placental development also were associated with the infant’s birth weight at delivery. Importantly, these changes seem to be connected to maternal stress and depression symptoms.

Taken as a whole, the findings suggest that the disturbances measured on placental development in the womb may influence the placenta’s ability to support fetal health and wellness. “We are continuing to follow up on these mother-baby dyads to determine the long-term functional significance of these placental changes in utero,” Dr. Limperopoulos said.

Studies have shown that the placenta adapts to negative changes in the maternal environment and mental health status, and disruptions in placental function impact infant brain development and children’s neurobehavior and temperament.

The patient benefit

Dr. Limperopoulos’s research studying childbirth amid the pandemic builds on her extensive work investigating the impact of maternal stress on unborn children, including its adverse effect on brain structure and biochemistry. She’s also working on treatments and interventions to better support new families. Her program, DC Mother-Baby Wellness, brings together community partners to provide wrap-around care to expectant and new moms with elevated scores for stress, anxiety and depression.

“When identified early, maternal stress is a modifiable risk factor that can be treated with psychotherapy, social support and other personalized, evidence-based interventions,” Dr. Limperopoulos said. “We look forward to continued research in this area to better understand the mechanisms behind these biological changes and the needs of mothers and children who are born during pandemics, natural disasters and other significantly stressful events.”

Using telehealth to study babies born to mothers infected with SARS-CoV-2

mother and baby doing a telehealth call

Continued advancements in telehealth methods to follow child neurodevelopment will help ensure robust child follow-up and inclusion of diverse cohorts.

Multiple studies have shown that SARS-CoV-2 infection can impact pregnant mothers and their fetuses but more research is needed to understand the long-term impact on the neurodevelopment of these children as they get older. Child neurodevelopmental evaluations are typically performed in-person. Since the COVID-19 pandemic began, the transition to telehealth methods was needed.

Continued advancements in telehealth methods to follow child neurodevelopment will help ensure robust child follow-up and inclusion of diverse cohorts, says a commentary in JAMA Network Open.

Why it matters

Commentary author Sarah Mulkey, M.D., prenatal-neonatal neurologist at Children’s National Hospital, highlights a new study that used a novel telehealth method to look for neurodevelopmental differences in infants ages 6-12 months born to mothers with SARS-CoV-2 infection compared to nonexposed infants of the same age and found no differences in neurodevelopment among the two cohorts. The study adapted a standardized assessment to a telehealth method.

“The results of this study provide needed reassurance to the many mothers who have experienced SARS-CoV-2 infection during pregnancy,” says Dr. Mulkey.

What’s been the hold up in the field?

“Developmental assessments that rely on observation of infants’ developmental skills can naturally make the transition to a telehealth platform,” says Sarah Mulkey, M.D., prenatal-neonatal neurologist at Children’s National Hospital and commentary author. “General movement assessment is an observation-based assessment of infants that can be captured by a parent or caregiver on video, and it has been used in neurodevelopmental outcomes studies of children after antenatal SARS-CoV-2 exposure.”

Moving the field forward

Child outcomes research can have improved enrollment and continuity of participant follow-up due to the availability of remote assessments. Neurodevelopmental tools are being developed that can be used on a telehealth platform or by parent recorded videos.

Researchers from the Children’s National Congenital Zika Virus Program have also developed telehealth-based methods for child outcome research that has been utilized in international Zika outcome studies funded by the Thrasher Research Fund and the NIH.

DC Mother Baby Wellness marks 1,000-referral milestone

Hand holding newborn baby's hand

Launched 18 months ago, the city-wide DC MBW program brings together prenatal care providers, pediatricians, community-based organizations and birthing hospitals to provide essential services to mothers and babies at high risk for adverse health outcomes.

Launched 18 months ago, the city-wide DC MBW program brings together prenatal care providers, pediatricians, community-based organizations and birthing hospitals to provide essential services to mothers and babies at high risk for adverse health outcomes. Using evidence-based screening and evaluation tools, the program provides timely and targeted resources – including mental health care for mothers, developmental screening and treatment for newborns and other support – to ensure that families with the most acute social and medical needs have access to culturally relevant resources.

“Healthy moms are the foundation of healthy families and communities,” says Catherine Limperopoulos, Ph.D., the program’s director and director of the Developing Brain Institute at Children’s National. “Perinatal mood and anxiety disorders are among the most common complications of pregnancy. By offering thoughtful, individualized mental health resources – in English and Spanish – we are improving outcomes for local families facing some of the most complex and challenging health needs.”

Dr. Limperopoulos has done extensive research on the profound, negative effects of expectant mothers’ stress on their unborn children. Using advanced fetal MRI technology, her published research continues to show that stress, anxiety or depression in pregnant mothers alters babies’ brain development. These mental health challenges are associated with poor obstetric outcomes and social, emotional and behavioral problems in children.

The DC MBW 1,000-referral milestone comes as Dr. Limperopoulos expands her research role at Children’s National with the creation of a new Center for Prenatal, Neonatal & Maternal Health Research that she will lead. Opened in April, the center will be a research hub for maternal health and prevalent pediatric disorders that may be present in the earliest stages of life.

At DC MBW, Dr. Limperopoulos and her team serve mostly women of color with complex social needs that drive their anxiety, stress, depression and other mental health concerns. More than a third of the mothers referred to the wellness program are experiencing housing insecurity at intake – a number that climbs to more than 75% during their pregnancy and first year postpartum. About 30% of referred women are experiencing food insecurity. One in four are experiencing intimate partner violence, and 10% report contemplating suicide.

Dr. Limperopoulos says the team’s data indicate expectant mothers’ symptoms of depression drop dramatically within as few as six weeks of engagement with the wellness program’s services. These mothers are supported during pregnancy and beyond, as they check in with their providers during primary care visits at various Children’s National locations, participate in interactive, evidence-based play to boost child development and attend prenatal group classes that start this spring.

“It is not an overstatement to say that this program has saved lives,” says Siobhan Burke, M.D., director of Obstetrics and Gynecology at Unity Health Care. “There are so many initiatives and programs that focus on screening for depression in pregnancy, but DC MBW is actually doing the work and getting patients the treatments that they want and need. The team has designed a program that focuses on removing barriers. Whether that’s things like transportation, insurance status or language barriers, they find a way to help.”

The Centers for Disease Control and Prevention reports that the U.S maternal death rate continues to climb locally and nationally. The rates for Black mothers are significantly higher than for white and Latina mothers, making early intervention and wrap-around healthcare services even more vital to reverse this sobering trend.

The DC MBW program was underwritten by a $36 million investment from the A. James & Alice B. Clark Foundation and has hired more than a dozen full-time experts who provide care coordination, psychotherapy and patient referrals to a range of community resources. Most often, patients are referred by providers at Unity Health Care, the George Washington University Hospital, MedStar Washington Hospital Center and other leading prenatal care practices in the city.

“I credit our team’s tireless efforts for achieving this milestone so quickly. I have witnessed firsthand the dedication, time and boundless energy that they have devoted to each and every one of these people, walking side by side with them on their journey toward wellness,” Dr. Limperopoulos says. “Our research clearly supports the need for the care and resources we provide through the DC Mother-Baby Wellness initiative. Through our existing referral collaborative, we look forward to welcoming even more patients to this city-wide network as we welcome their babies into the world.”

Children’s National Hospital researchers will develop new diagnostic tools and precision medicine for unborn children, babies and young children at the hospital’s newly established Center for Prenatal, Neonatal & Maternal Health Research.

Children’s National Hospital researchers will develop new diagnostic tools and precision medicine for unborn children, babies and young children at the hospital’s newly established Center for Prenatal, Neonatal & Maternal Health Research.

The investment comes as research continues to show the importance of high-quality, evidence-based care at this crucial stage of pediatric development, especially for underserved families. The center is the sixth organization to join the Children’s National Research Institute.

What we hope to discover

“We know that many chronic diseases that crop up during adulthood have their footprint in the womb,” said center Director Catherine Limperopoulos, Ph.D.  “While this concept has been around for years, our new center will provide a unique opportunity to study such research questions as the role of prenatal stressors on long-term outcomes. And we’ll be able to provide interventions earlier, improving mothers’ outcomes sooner. This benefits the mom, the fetus, the child and has implications for the next generation.”

Limperopoulos’s research will continue the hospital’s longstanding investment in improving the understanding, prevention and treatment of childhood diseases. The center will foster collaborations throughout the hospital by teaming with experts in neuroscience, oncology, genetics and other disciplines that are vital for safeguarding the health of mothers and their babies, even before they’re born.

“We know that many chronic diseases that crop up during adulthood have their footprint in the womb,” said center Director Catherine Limperopoulos, Ph.D.  “While this concept has been around for years, our new center will provide a unique opportunity to study such research questions as the role of prenatal stressors on long-term outcomes.

Limperopoulos will also continue to serve as the director of the Children’s National Developing Brain Institute, which focuses on the brain in utero, after birth and throughout preschool. Her research is paving the way toward understanding how maternal stress impacts fetal brain development and helping to advance perinatal mental health while addressing racial disparities in access to care. The center will also partner with clinical leaders throughout Children’s National and community partners to expand existing efforts, such as the DC Mother-Baby Wellness Initiative, an innovative program that Limperopoulos leads.

“The care of mothers and their young children will change dramatically in the next decade, and the breadth of our research has the power to lead the way in harnessing medical advancements to nurture healthier families,” Limperopoulos said. “Imagine a day when we can identify in utero a biomarker for a disorder such as sickle cell disease and prevent the disease from taking hold with a novel therapy. This is the vision for the groundbreaking research that will happen at the new center.”
