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.”

Will SARS-CoV-2 during pregnancy impact child’s neurodevelopment?

coronavirus and DNA

Sarah Mulkey, M.D., prenatal-neonatal neurologist at Children’s National, will lead the neurodevelopmental evaluations of the infants born to mothers with SARS-CoV-2 infection during pregnancy to understand any long-term neurological effects in offspring.

Scientists led by the Lieber Institute for Brain Development are studying how a mother’s SARS-CoV-2 infection during pregnancy affects the biology of the placenta and the corresponding trajectory of the child’s brain development, including the risk for neurodevelopmental disorders such as schizophrenia and autism. The work is made possible by a $3 million, five-year grant from the Eunice Kennedy Shriver National Institute of Child Health & Human Development, part of the National Institutes of Health.

The project stems from a collaboration between the Lieber Institute for Brain Development on the Johns Hopkins medical campus in Baltimore, Children’s National Hospital in Washington, D.C., and the Women’s Health Integrated Research Center at Inova Health System in Virginia.

The big picture

The group aims for a clearer picture of how a mother’s SARS-CoV-2 infection during pregnancy affects neurodevelopment in utero, the effects of which may manifest early in a child’s life. The researchers hope to understand how the infection interacts with other factors relevant to brain development, including genomic risk for neurodevelopmental disorders, maternal stress and social determinants of health.

The team will study whether the relationship between maternal SARS-CoV-2 infection and offspring brain development is mediated by changes in the biology of the placenta and the activation of the mother’s immune system. They will also gauge any differences in the effects of SARS-CoV-2 between female and male children and in the offspring of vaccinated and unvaccinated mothers.

Why it matters

Preliminary data show that pregnant people with symptomatic SARS-CoV-2 infections are more likely to have a preterm delivery, abnormalities in the placenta and prenatal and perinatal complications such as preeclampsia and fetal growth restriction. All these complications have been found to increase a child’s risk of neurodevelopmental disorders later in life.

What we hope to discover

Sarah Mulkey, M.D., prenatal-neonatal neurologist at Children’s National, will lead the neurodevelopmental evaluations of the infants born to mothers with SARS-CoV-2 infection during pregnancy to understand any long-term neurological effects in offspring. The researchers will evaluate the children’s neurodevelopment at both 24 and 36 months of age. This work builds upon Dr. Mulkey’s longitudinal neurodevelopmental evaluations in children exposed to Zika virus in utero.

“What we’ve learned is that even when babies don’t have Zika-virus-related birth defects, we still find differences in early child development compared to children who weren’t exposed to Zika virus,” said Dr. Mulkey. “With SARS-CoV-2, there is still so much we don’t know. But by better understanding the long-term impact of COVID exposure during pregnancy, we can ultimately find ways to prevent adverse outcomes.”

Recommendations for management of positive monosomy X on cell-free DNA screening

woman getting blood draw

In a study published in the American Journal of Obstetrics and Gynecology, researchers provide context and expert recommendations for maternal and fetal evaluation and management when cfDNA screening is positive for monosomy X or Turner Syndrome (TS).

Non-invasive prenatal testing (NIPT) using cell-free DNA (cfDNA) is currently offered to all pregnant women regardless of the fetal risk. While this test has excellent value to screen for chromosomal abnormalities such as Down syndrome, the test has a much lower positive predictive value for sex-chromosome abnormalities such as Turner syndrome. In a study published in the American Journal of Obstetrics and Gynecology, researchers provide context and expert recommendations for maternal and fetal evaluation and management when cfDNA screening is positive for monosomy X or Turner Syndrome (TS).

The manuscript was put together by the Turner Syndrome Special Interest Group (TS SIG) of the Pediatric Endocrine Society, chaired by Roopa Kanakatti Shankar, M.D., endocrinologist at Children’s National Hospital, along with other specialists including a gynecologist, maternal fetal medicine expert, cardiologists and pediatric endocrinologists.

The big picture

The field of NIPT using cfDNA testing has advanced considerably making it routine in the care of pregnant women and more couples are opting for it. This will lead to an increased detection of monosomy X overall — some of which may be true positives, but others may be false positives, or even an indicator of maternal TS rather than an affected fetus. This article discusses the changing landscape and provides an expert opinion on how to manage these scenarios.

How does this work move the field forward?

“We hope that this will increase provider knowledge and recognition of the pitfalls of NIPT as a screening test for sex-chromosome disorders such as monosomy X,” says Dr. Kanakatti Shankar. “It will also provide a framework for the next diagnostic steps, management and referrals that a provider may take to optimize care for both mother and child.”

How is Children’s National leading in this space?

Current guidelines for the care of individuals with TS throughout the lifespan do not specifically address management of individuals with a cell-free DNA screen positive for monosomy X.

“As chair of the TS Special Interest Group, I was able to lead this unique collaborative effort which we hope will lead to better understanding of NIPT results in the context of TS and for multispecialty providers to improve prenatal detection and timely care,” says Dr. Kanakatti Shankar.

Early SARS-CoV-2 exposure may impact infant development

pregnant woman

The study found that some infants with in utero or early-life exposure to SARS-CoV-2 had borderline to low developmental screening scores.

Early SARS-CoV-2 exposure may impact neurodevelopment, especially among infants exposed in utero to symptomatic parents. This is according to a new study led by Sarah Mulkey, M.D., Ph.D., prenatal-neonatal neurologist in the Prenatal Pediatrics Institute at Children’s National Hospital. Dr. Mulkey and team conclude that vaccination and other precautions to reduce early-in-life infection may protect against neurodevelopmental delays. Children with early SARS-CoV-2 exposure should have additional long-term screening for neurodevelopmental delays.

Children’s National Hospital leads the way

The developing brain is vulnerable to both direct and indirect effects of infection during pregnancy and in the early neonatal period. To chart the impact of this exposure, the team created a clinical follow-up protocol in the Congenital Infection Program at Children’s National to chart the development of 34 infants exposed to SARS-CoV-2 in utero or in the neonatal period.

What we hoped to discover

“We conducted this study because we know that infants, when exposed to maternal COVID-19 infection in utero can be exposed to inflammation, fever and an abnormal intrauterine environment. SARS-CoV-2 can also affect the placenta, and in turn, the developing brain,” Dr. Mulkey shared with Healio.

This study aimed to determine if infants with early SARS-CoV-2 exposure developed abnormal neurodevelopment in infancy and the factors that may impact neurodevelopment differences. The study found that some infants with in utero or early-life exposure to SARS-CoV-2 had borderline to low developmental screening scores, most common among babies born to mothers with symptomatic COVID-19. Researchers followed the infants in their first months of life, gauging how the exposure affected their neurologic development. Results were demonstrated using a screening test called the Ages & Stages Questionnaires (ASQ), and those whose scores were borderline or low were most often born to mothers with symptomatic COVID-19.

Why it matters

In conducting this study, the team found that babies born during the pandemic, specifically under these conditions, do, in fact, require additional follow-up in the early stages of life. We may also see more differences in developmental outcomes as children get older.

“Any measure we can take to help prevent infections for mothers in their pregnancy can improve long-term developmental outcomes for children,” says Dr. Mulkey.

Other members of the Children’s National team that contributed to this work include Roberta L. DeBiasi, M.D., M.S.; Meagan E. Williams, M.S.P.H.; Nadia Jadeed, R.N.C.; Anqing Zhang, Ph.D.; and Smitha Israel, B.S.N.

Dr. Mulkey also published a recent article in the American Journal of Obstetrics & Gynecology that found the COVID-19 vaccine may protect pregnant women from SARS-CoV-2 placentitis and stillbirth. This work builds upon Dr. Mulkey’s longitudinal studies on Zika virus infection in pregnancy and long-term impacts on the child, funded by the Thrasher Research Fund and the National Institutes of Health.

Exposure to Zika in utero may produce neurodevelopmental differences

Sarah Mulkey

“There are still many unanswered questions about the long-term impacts of Zika on children exposed in utero,” says Sarah Mulkey, M.D., Ph.D., a prenatal-neonatal neurologist in the Prenatal Pediatrics Institute at Children’s National Hospital.

Children who are exposed to the Zika virus while in the womb, but who are not subsequently diagnosed with Zika-related birth defects and congenital Zika syndrome (CZS), may still display differences in some aspects of cognitive development, mood and mobility compared to unexposed children, reports a study published in Pediatric Research. These findings suggest that Zika-exposed children may need some additional support and monitoring as they get older.

“There are still many unanswered questions about the long-term impacts of Zika on children exposed in utero,” says Sarah Mulkey, M.D., Ph.D., a prenatal-neonatal neurologist in the Prenatal Pediatrics Institute at Children’s National Hospital and the study’s first author. “These findings are another piece of the puzzle that provides insight into the long-term neurodevelopment of children with prenatal Zika virus exposure. Further evaluation is needed as these children get older.”

It has not been clear how children who were exposed to the Zika virus in the womb during the 2015–2017 epidemic, but who did not develop CZS and serious neurological complications, will develop as they get older.

Dr. Mulkey and colleagues examined the neurodevelopment of 55 children aged 3-5 years who were exposed to Zika in the womb in Sabanalarga, Colombia, and compared them to 70 control children aged 4-5 years who had not been exposed to Zika. Assessments occurred between December 2020 and February 2021. Health professionals tested the children’s motor skills (such as manual dexterity, aiming and catching, and balance) and their readiness for school (including knowledge of colors, letters, numbers and shapes). Parents completed three questionnaires providing information about their child’s cognitive function (such as memory and emotional control), behavioral and physical conditions (such as responsibility and mobility), and their parenting experience (including whether they felt distress).

Parents of Zika-exposed children reported significantly lower levels of mobility and responsibility compared to control children, although differences in cognitive function scores were not significant. Additionally, parents of 6 (11%) Zika-exposed children reported mood problems compared to 1 (1%) of control children, and Zika-exposed parents were significantly more likely to report parental distress.

Professional testing revealed no significant differences in the Zika-exposed children’s manual dexterity, such as their ability to catch an object or post a coin through a slot, compared to the control children. Both Zika-exposed and control children also scored lowly on readiness for school.

The authors highlight that parental responses may have been influenced by the Zika-exposed children’s parents’ perceptions or increased worry about the development of their child. Some differences in results may also have been caused by the age – and therefore developmental – differences between the groups of children.

The authors conclude that while these Zika-exposed children are making progress as they develop, they may need additional support as they prepare to start school.

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.

COVID-19 vaccine may protect pregnant women from SARS-CoV-2 placentitis and stillbirth

pregnant woman getting vaccinated

In a new article published in the American Journal of Obstetrics & Gynecology, researchers conclude that the vaccine not only protects pregnant women but may also be lifesaving for their unborn children.

Stillbirth is a recognized complication of COVID-19 in pregnant women caused by harmful changes to the placenta induced by the virus. Termed SARS-CoV-2 placentitis, it can render the placenta incapable of providing oxygen to the fetus, leading to stillbirth and neonatal death. Researchers now suggest that pregnant women who get the COVID-19 vaccine may be protected from SARS-CoV-2 placentitis and stillbirth. In a new article published in the American Journal of Obstetrics & Gynecology, researchers conclude that the vaccine not only protects pregnant women but may also be lifesaving for their unborn children.

The extensive examination of published literature involved reviewing nearly 100 papers looking at COVID-19’s impacts on pregnant women and the effects on the placenta and pregnancy outcome. Sarah Mulkey, M.D., Ph.D., a prenatal-neonatal neurologist in the Division of Prenatal Pediatrics at Children’s National Hospital and co-author of the article, says the findings make a strong case for vaccination.

“The COVID-19 virus fortunately does not cause birth defects like other viruses such Zika, but it can cause severe injury to the placenta that can result in stillbirth and other pregnancy complications,” says Dr. Mulkey. “I hope patients who are pregnant or planning to become pregnant can learn how the COVID vaccine may help keep them and their baby healthy throughout pregnancy from some of the worst effects of this virus.”

While stillbirths can have many causes, the data analyzed supports that the COVID-19 vaccine is beneficial for pregnancies and for reducing the risk of stillbirth by reducing the risk of the virus impacting the placenta.

“In the multiple reports of SARS-CoV-2 placentitis that have been associated with stillbirths and neonatal deaths, none of the mothers had received COVID-19 vaccinations,” says David Schwartz, M.D., lead author, epidemiologist and perinatal pathologist. “And although not constituting proof, we’re not aware, either personally, via collegial networks, or in the published literature, of any cases of SARS-CoV-2 placentitis causing stillbirths among pregnant women having received the COVID-19 vaccine.”

Earlier in 2022, Dr. Schwartz led a team from 12 countries that found SARS-CoV-2 placentitis destroyed an average of 77.7% of placental tissue, resulting in placental insufficiency and fetal death, all occurring in unvaccinated mothers.

Fortunately, the large majority of pregnancies affected by a COVID-19 infection do not result in stillbirth. The development of SARS-CoV-2 placentitis is complex and likely involves both viral and immunological factors. The characteristics of a SARS-CoV-2 variant may also affect risk.

“Placental pathology is an important component in understanding the pathophysiology of SARS-CoV-2 infection during pregnancy,” says Dr. Mulkey.

As part of the Congenital Infection Program at Children’s National, Dr. Mulkey has been following infants born to mothers who had SARS-CoV-2 infection during pregnancy since the beginning of the pandemic. She will present the results of the early neurodevelopment of these infants at ID Week in Washington, D.C., on Oct. 22, 2022. Dr. Mulkey will also lead the neurodevelopmental follow-up of a large cohort of infants born to mothers with SARS-CoV-2 infection during pregnancy to better understand any long-term neurological effects to offspring.

The study builds upon Dr. Mulkey’s longitudinal studies on Zika virus infection in pregnancy and long-term impacts on the child that is funded by the Thrasher Research Fund.

Children’s National named to U.S. News & World Report’s Best Children’s Hospitals Honor Roll

US News BadgesChildren’s National Hospital in Washington, D.C., was ranked No. 5 nationally in the U.S. News & World Report 2022-23 Best Children’s Hospitals annual rankings. This marks the sixth straight year Children’s National has made the list, which ranks the top 10 children’s hospitals nationwide. In addition, its neonatology program, which provides newborn intensive care, ranked No.1 among all children’s hospitals for the sixth year in a row.

For the twelfth straight year, Children’s National also ranked in all 10 specialty services, with seven specialties ranked in the top 10.

“In any year, it would take an incredible team to earn a number 5 in the nation ranking. This year, our team performed at the very highest levels, all while facing incredible challenges, including the ongoing pandemic, national workforce shortages and enormous stress,” said Kurt Newman, M.D., president and chief executive officer of Children’s National. “I could not be prouder of every member of our organization who maintained a commitment to our mission. Through their resilience, Children’s National continued to provide outstanding care families.”

“Choosing the right hospital for a sick child is a critical decision for many parents,” said Ben Harder, chief of health analysis and managing editor at U.S. News. “The Best Children’s Hospitals rankings spotlight hospitals that excel in specialized 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.

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.

Stress during pregnancy may hinder cognitive development

pregnant woman by window

This is the first study to shed light on an important link between altered in-utero fetal brain development and the long-term cognitive development consequences for fetuses exposed to high levels of toxic stress during pregnancy.

Women’s elevated anxiety, depression and stress during pregnancy altered key features of the fetal brain, which subsequently decreased their offspring’s cognitive development at 18 months. These changes also increased internalizing and dysregulation behaviors, according to a new study by Children’s National Hospital published in JAMA Network Open. Researchers followed a cohort of 97 pregnant women and their babies. The findings further suggest that persistent psychological distress after the baby is born may influence the parent-child interaction and infant self-regulation.

This is the first study to shed light on an important link between altered in-utero fetal brain development and the long-term cognitive development consequences for fetuses exposed to high levels of toxic stress during pregnancy. While in the womb, the researchers observed changes in the sulcal depth and left hippocampal volume, which could explain the neurodevelopment issues seen after birth. Once they grow into toddlers, these children may experience persistent social-emotional problems and have difficulty establishing positive relationships with others, including their mothers. To further confirm this, future studies with a larger sample size that reflect more regions and populations are needed.

“By identifying the pregnant women with elevated levels of psychological distress, clinicians could recognize those babies who are at risk for later neurodevelopmental impairment and might benefit from early, targeted interventions,” said Catherine Limperopoulos, Ph.D., chief and director of the Developing Brain Institute at Children’s National and senior author of the study.

“By identifying the pregnant women with elevated levels of psychological distress, clinicians could recognize those babies who are at risk for later neurodevelopmental impairment and might benefit from early, targeted interventions,” said Catherine Limperopoulos, Ph.D., chief and director of the Developing Brain Institute at Children’s National and senior author of the study.

Regardless of their socioeconomic status, about one of every four pregnant women suffers from stress-related symptoms, the most common pregnancy complication. The relationship between altered fetal brain development, prenatal maternal psychological distress and long-term neurodevelopmental outcomes remain unknown. Studying in utero fetal brain development poses challenges due to fetal and maternal movements, imaging technology, signal-to-noise ratio issues and changes in brain growth.

All pregnant participants were healthy, most had some level of education and were employed. To quantify prenatal maternal stress, anxiety and depression, the researchers used validated self-reported questionnaires. Fetal brain volumes and cortical folding were measured from three-dimensional reconstructed images derived from MRI scans. Fetal brain creatine and choline were quantified using proton magnetic resonance spectroscopy. The 18-month child neurodevelopment was measured using validated scales and assessments.

This study builds upon previous work from the Developing Brain Institute led by Limperopoulos, which discovered that anxiety in pregnant women appears to affect the brain development of their babies. Her team also found that maternal mental health, even for women with high socioeconomic status, alters the structure and biochemistry of the developing fetal brain. The growing evidence underscores the importance of mental health support for pregnant women.

“We’re looking at shifting the health care paradigm and adopting these changes more broadly to better support moms,” said Limperopoulos. “What’s clear is early interventions could help moms reduce their stress, which can positively impact their symptoms and thereby their baby long after birth.”

Mothers who are Hispanic or who come from rural or low socioeconomic status neighborhoods are less likely to have their child’s critical heart condition diagnosed before birth, according to a new study in the journal Circulation.

This is the largest and most geographically diverse study of these challenges to date. The study compared patient data of more than 1,800 children from the United State and Canada diagnosed with two of the most common, and the most serious, critical congenital heart defects: hypoplastic left heart syndrome (HLHS), when the left side of the heart is not developed completely, and transposition of the great arteries (TGA), when the two main arteries that carry blood away from the heart are reversed.

“The earlier we diagnose a heart defect, especially a serious one such as HLHS or TGA, the sooner we can make a plan for how to safely deliver the infant and reduce the impacts of that heart defect on the rest of the body,” says Anita Krishnan, M.D., first author and cardiologist at Children’s National Hospital. “Early detection and diagnosis of these conditions is crucial to ensuring the best possible outcome for the child, especially in protecting the brain.”

Even when infants’ heart defects were detected before birth, babies from neighborhoods with lower socioeconomic status were detected later in gestation than others.

“The COVID-19 pandemic has brought the idea of significant disparities in health care to the forefront of our national attention,” says Dr. Krishnan. “Even though many health care providers have seen these inequities firsthand in their own clinical experience, it was still surprising to see the strength of the association between socioeconomic position and the care available to mothers.”

In both the United States and Canada, expectant mothers are first screened as part of routine prenatal care in the first trimester for early signs of congenital heart defects and other genetic disorders via blood screen and ultrasound. In the second trimester, a comprehensive ultrasound evaluation for structural anomalies is routine. If any issues are detected, the mother is referred for a fetal echocardiogram and counseling.

The authors suggest that decreased linkages between neighborhoods and people identified in the study and subspecialists could contribute to the disparities found in the study.

“Prenatal detection rates may improve if we are able to leverage outreach and telehealth to strengthen the relationships between these specialties and the groups we identified in the study,” Dr. Krishnan says.

The study included a total of 1,862 patients, including 1,171 patients with HLHS (91.8% prenatally diagnosed) and 691 with TGA (58% prenatally diagnosed). The study group included prenatally diagnosed fetuses with HLHS or TGA and postnatally diagnosed infants less than two months old with HLHS or TGA. Data was collected from institutions participating in the Fetal Heart Society, a non-profit 501(c) multicenter research collaborative with a mission to advance the field of fetal cardiovascular care and science. Mary Donofrio, M.D., director of Prenatal Cardiology at Children’s National, is society president and served as a senior author on this study.

Mothers and their babies often experience stress, depression and anxiety, which impacts the infant’s brain development.

Children’s National Hospital announces a $4.2 million funding award from the Patient-Centered Outcomes Research Institute (PCORI) to support maternal mental health research. The Developing Brain Institute at Children’s National will lead a new program that seeks to advance perinatal mental health and well-being while addressing racial disparities in access to resources that could boost positive health outcomes for women with few opportunities.

Mothers and their babies often experience stress, depression and anxiety, which impacts the infant’s brain development. Maternal psychological distress is more pronounced among low-income mothers — a health disparity that was exacerbated during the COVID-19 pandemic.

“The new fund will support many scientific research portfolios, including our project that will ensure pregnant women in D.C. get the care they need and deserve,” said Catherine Limperopoulos, Ph.D., director of The Developing Brain Institute at Children’s National and co-principal investigator of the project.

“I’m honored to be working alongside Dr. Limperopoulos and our partners. Collectively, our team aims to meet the needs of African American pregnant and postpartum women and their families during this important transition in their lives by providing services to address social determinants of health and prevent and treat maternal distress,” said Huynh-Nhu Le, Ph.D., the co-principal investigator of the project and professor in the Clinical Psychology program, part of the department of Psychological and Brain Sciences at George Washington University.

Cognitive-behavioral intervention, patient navigation and peer support, such tailored strategies developed in the program will provide effective mental health screening and care for 1,000 mothers living in Washington D.C. that is responsive to their cultural, social, environmental, behavioral and medical needs. The participants will access the resources either online or in-person, depending on the type of assistance that fits their lifestyle.

“I am overjoyed that PCORI has provided this essential funding, giving life to our project. The research done here will have a grand effect! Our goals are ambitious: To dissect all aspects of maternal health, beyond just mental health, literally creating a detailed timeline of events a mother can anticipate experiencing from pregnancy, at delivery and postpartum,” said Shanae Bond, one of the women whose firsthand experience giving birth in D.C. informed the study design. “With the maternal health crisis we are currently facing, it’s imperative to gain this type of insight to not only support mothers but to learn how they wish to be supported and how to best improve the care they receive – based on how it impacts, improves (or impairs) their lives,” said Bond.

The multidisciplinary group includes doctors, midwives, psychologists, advisors, community leaders and four prenatal care centers, MedStar Washington Hospital Center, Howard University, The George Washington University and Unity Health Care.

“Our initiative brings together obstetrics, pediatrics, and mental health care in an integrated care model. This collaboration brings early identification and immediate care coordination to its rightful place at the center of care,” said Loral Patchen, Ph.D., CNM, vice chair, Innovation and Community Programs at MedStar Washington Hospital Center. “The prenatal period offers an opportunity for us to support emotional healing, build coping strategies, and offer a safe space for people to prepare for the complex transitions that accompany childbearing. Offering services prior to delivery optimizes opportunity for strong parent-infant attachment and mitigates potential disruptions.”

Kristin L. Atkins, M.D., FACOG, assistant professor in the Obstetrics and Gynecology Department at Howard University College of Medicine, mentioned that Howard University is honored to partner with Children’s National Hospital. “The new program will help discover more about prenatal care interventions related to maternal mental health and how they may impact fetal and pediatric brain development,” said Dr. Atkins. “We are just discovering the impact of long-standing stress on health and well-being, and this starts in utero.”

To Jennifer Keller, M.D., MPH, FACOG, associate professor at The George Washington University School of Medicine & Health Sciences, this project is essential. “The events of the last year have had a profound impact on families in this city,” said Dr. Keller. “This project begins at a time of critical mental health needs for pregnant people in D.C.”

Siobhan Burke, M.D., director of OB/GYN at Unity Health Care, is also thrilled to be part of this partnership. “We all know underlying stressors such as financial difficulties, housing instability and systemic racism can impact health, but it’s important to find out what these things do to the developing fetus and to explore strategies to make lives better,” said Dr. Burke.

In 2020, Children’s National established The Clark Parent & Child Network funded by a $36 million investment from the A. James & Alice B. Clark Foundation. The Clark Network aims to provide families with greater access to mental health care and community resources. New projects like the D.C. mother-infant behavioral wellness program underwritten by PCORI funding will become natural extensions of this essential work.

“This project was selected for PCORI funding not only for its scientific merit and commitment to engaging patients and other stakeholders, but also for its potential to fill an important gap in our health knowledge and give people information to help them weigh the effectiveness of their care options,” said PCORI Executive Director Nakela L. Cook, M.D., M.P.H.. “We look forward to following the study’s progress and working with Children’s National Hospital to share the results.”

This $4.2 million PCORI funding has been approved pending completion of a business and programmatic review by PCORI staff and issuance of a formal award contract.

Low parental socioeconomic status alters brain development in unborn babies

doctor examining pregnant woman

A first-of-its-kind study with 144 pregnant women finds that socioeconomic status (SES) has an impact in the womb, altering several key regions in the developing fetal brain as well as cortical features.

Maternal socioeconomic status impacts babies even before birth, emphasizing the need for policy interventions to support the wellbeing of pregnant women, according to newly published research from Children’s National Hospital.

A first-of-its-kind study with 144 pregnant women finds that socioeconomic status (SES) has an impact in the womb, altering several key regions in the developing fetal brain as well as cortical features. Parental occupation and education levels encompassing populations with lower SES hinder early brain development, potentially affecting neural, social-emotional and cognitive function later in the infant’s life.

Having a clear understanding of early brain development can also help policymakers identify intervention approaches such as educational assistance and occupational training to support and optimize the well-being of people with low SES since they face multiple psychological and physical stressors that can influence childhood brain development, Lu et al. note in the study published in JAMA Network Open.

“While there has been extensive research about the interplay between socioeconomic status and brain development, until now little has been known about the exact time when brain development is altered in people at high-risk for poor developmental outcomes,” said Catherine Limperopoulos, Ph.D., director of the Developing Brain Institute and senior author. “There are many reasons why these children can be vulnerable, including high rates of maternal prenatal depression and anxiety. Later in life, these children may experience conduct disorders and impaired neurocognitive functions needed to acquire knowledge, which is the base to thrive in school, work or life.”

The findings suggest that fetuses carried by women with low socioeconomic backgrounds had decreased regional brain growth and accelerated brain gyrification and surface folding patterns on the brain. This observation in lower SES populations may in part be explained by elevated parental stress and may be associated with neuropsychiatric disorders and mental illness later in life.

In contrast, fetuses carried by women with higher education levels, occupation and SES scores showed an increased white matter, cerebellar and brainstem volume during the prenatal period, and lower gyrification index and sulcal depth in the parietal, temporal and occipital lobes of the brain. These critical prenatal brain growth and development processes lay the foundation for normal brain function, which ready the infant for life outside the womb, enabling them to attain key developmental milestones after birth, including walking, talking, learning and social skills.

There is also a knowledge gap in the association between socioeconomic status and fetal cortical folding — when the brain undergoes structural changes to create sulcal and gyral regions. The study’s findings of accelerated gyrification in low SES adds to the scientific record, helping inform future research, Limperopoulos added.

The Children’s National research team gathered data from 144 healthy women at 24 to 40 weeks gestation with uncomplicated pregnancies. To establish the parameters for socioeconomic status, which included occupation and education in lieu of family income, parents completed a questionnaire at the time of each brain magnetic resonance imaging (MRI) visit. The researchers used MRI to measure fetal brain volumes, including cortical gray matter, white matter, deep gray matter, cerebellum and brain stem. Out of the 144 participants, the scientists scanned 40 brain fetuses twice during the pregnancy, and the rest were scanned once. The 3-dimensional computational brain models among healthy fetuses helped determine fetal brain cortical folding.

Potential proximal risk factors like maternal distress were also measured in the study using a questionnaire accounting for 60% of the participants but, according to the limited data available, there was no significant association with low and high socioeconomic status nor brain volume and cortical features.

Associations Between Resting State Functional Connectivity and Behavior in the Fetal Brain

Maternal anxiety affects the fetal brain

Associations Between Resting State Functional Connectivity and Behavior in the Fetal Brain

Anxiety in gestating mothers appears to affect the course of brain development in their fetuses, changing neural connectivity in the womb, a new study suggests.

Anxiety in gestating mothers appears to affect the course of brain development in their fetuses, changing neural connectivity in the womb, a new study by Children’s National Hospital researchers suggests. The findings, published Dec. 7, 2020, in JAMA Network Open, could help explain longstanding links between maternal anxiety and neurodevelopmental disorders in their children and suggests an urgent need for interventions to diagnose and decrease maternal stress.

Researchers have shown that stress, anxiety or depression in pregnant mothers is associated not only with poor obstetric outcomes but also social, emotional and behavioral problems in their children. Although the care environment after birth complicates the search for causes, postnatal imaging showing significant differences in brain anatomy has suggested that these problems may originate during gestation. However, direct evidence for this phenomenon has been lacking, says Catherine Limperopoulos, Ph.D., director of the Developing Brain Institute at Children’s National.

To help determine where these neurological changes might get their start, Dr. Limperopoulos, along with staff scientist Josepheen De Asis-Cruz, M.D., Ph.D., and their Children’s National colleagues used a technique called resting-state functional magnetic resonance imaging (rs-fMRI) to probe developing neural circuitry in fetuses at different stages of development in the late second and third trimester.

The researchers recruited 50 healthy pregnant volunteers from low-risk prenatal clinics in the Washington, D.C. area who were serving as healthy “control” volunteers in a larger study on fetal brain development in complex congenital heart disease. These study participants, spanning between 24 and 39 weeks in their pregnancies, each filled out widely used and validated questionnaires to screen for stress, anxiety and depression. Then, each underwent brain scans of their fetuses that showed connections between discrete areas that form circuits.

After analyzing rs-fMRI results for their fetuses, the researchers found that those with higher scores for either form of anxiety were more likely to carry fetuses with stronger connections between the brainstem and sensorimotor areas, areas important for arousal and sensorimotor skills, than with lower anxiety scores. At the same time, fetuses of pregnant women with higher anxiety were more likely to have weaker connections between the parieto-frontal and occipital association cortices, areas involved in executive and higher cognitive functions.

“These findings are pretty much in keeping with previous studies that show disturbances in connections reported in the years and decades after birth of children born to women with anxiety,” says Dr. De Asis-Cruz. “That suggests a form of altered fetal programming, where brain networks are changed by this elevated anxiety even before babies are born.”

Whether these effects during gestation themselves linger or are influenced by postnatal care is still unclear, adds Dr. Limperopoulos. Further studies will be necessary to follow children with these fetal differences in neural connectivity to determine whether these variations in neural circuitry development can predict future problems. In addition, it’s unknown whether easing maternal stress and anxiety can avoid or reverse these brain differences. Dr. Limperopoulos and her colleagues are currently studying whether interventions that reduce stress could alter the trajectory of fetal neural development.

In the meantime, she says, these findings emphasize the importance of making sure pregnant women have support for mental health issues, which helps ensure current and future health for both mothers and babies.

“Mental health problems remain taboo, especially in the peripartum period where the expectation is that this is a wonderful time in a woman’s life. Many pregnant mothers aren’t getting the support they need,” Dr. Limperopoulos says. “Changes at the systems level will be necessary to chip away at this critical public health problem and make sure that both mothers and babies thrive in the short and long term.”

Dr. Youssef Kousa awarded Pediatric Epilepsy Research Grant

zika virus

The Child Neurology Foundation has awarded Youssef A. Kousa, M.S., D.O., Ph.D., the 2020 Pediatric Epilepsy Research Foundation Shields Research Grant. The funds will support his work on identifying genetic risk factors in congenital Zika syndrome.

The Child Neurology Foundation has awarded Youssef A. Kousa, M.S., D.O., Ph.D., physician-scientist within the Division of Neurology at Children’s National Hospital, and founder and director of the Zika Genetics Consortium, the 2020 Pediatric Epilepsy Research Foundation Shields Research Grant. The funds will support his work on identifying genetic risk factors in congenital Zika syndrome.

This prestigious grant provides $100,000 of research funding to help identify treatments and cures for pediatric neurologic diseases. It will allow Dr. Kousa to test the hypothesis that rare genetic variants in individuals contributed to being affected with congenital Zika syndrome and the severity of the phenotype for those who were affected.

“Despite decades of research, identifying those at greatest risk of congenital infection or being severely affected remains an elusive goal,” says Dr. Kousa. “This research is important because identifying genetic risk or protective factors for developmental brain malformations can help teach us how the brain develops.”

Youssef Kousa

In 2015, Dr. Kousa established the Zika Genetic Consortium to investigate whether maternal and fetal genetic factors can modify the risk of brain injury from congenital infections.

Dr. Kousa adds that this work will provide key insights into maternal and fetal genetic factors that can contribute to brain malformations. The hope is that these insights may one day translate into targeted prevention efforts.

“Dr. Kousa’s project is very creative and has a fantastic opportunity to look at factors of Zika on brain development,” says William D. Gaillard, M.D., division chief of both Epilepsy and Neurophysiology, and Neurology at Children’s National. “This is a very competitive award. It’s a tremendous achievement that few accomplish.”

Children’s National is the leading site for this international research study.

In 2015, Dr. Kousa established the Zika Genetic Consortium to investigate whether maternal and fetal genetic factors can modify the risk of brain injury from congenital infections. Dr. Kousa is the principal investigator of the consortium, which includes 19 co-investigators representing 13 different institutions.

The consortium is bringing together cohorts of 12,000 mother-infant participants retrospectively and prospectively. These cohorts come from 15 international health centers in seven countries in collaboration with partners at the National Institutes of Health, and the Centers for Disease Control and Prevention.

“This support gives us the opportunity to test our hypothesis,” says Dr. Kousa. “We also hope what we continue to learn about Zika can play a role in helping us understand other congenital infections and neurodevelopment diseases.”

The importance of following the Zika population long-term

zika virus

Invited commentary by Sarah Mulkey, M.D., Ph.D., prenatal-neonatal neurologist in the Division of Prenatal Pediatrics at Children’s National Hospital, emphasizes importance of studying the Zika population long term.

A simple measuring tape could be the key to identifying which children could develop neurological and developmental abnormalities from Zika virus exposure during gestation. This is according to an invited commentary published July 7, 2020 in JAMA Network Open and written by Sarah Mulkey, M.D., Ph.D., prenatal-neonatal neurologist in the Division of Prenatal Pediatrics at Children’s National Hospital.

Zika virus (ZIKV), first isolated in 1947 in the Zika Forest in Uganda, made headlines in 2015-2016 for causing a widespread epidemic that spread through parts of North and South America, several islands in the Pacific and parts of Southeast Asia. Although previously linked with no or mild symptoms, researchers discovered during this epidemic that Zika can cross from a pregnant woman to her gestating fetus, leading to a syndrome marked by microcephaly (decreased brain growth), abnormal neurologic tone, vision and hearing abnormalities and joint contractures.

“For the 90% to 95% of ZIKV-exposed infants who fortunately were not born with severe abnormalities at birth and were normocephalic, our hope was that these children would have normal neurodevelopmental outcomes,” Dr. Mulkey writes in the commentary. “Unfortunately, this has not been the case.”

Her commentary expands on a study in the same issue entitled “Association between exposure to antenatal Zika virus and anatomic and neurodevelopmental abnormalities in children” by Cranston et al. In this study, the researchers find that head circumference — a simple measure taken regularly at postnatal appointments in the U.S. — can provide insight into which children were most likely to develop neurologic abnormalities. Their findings show that 68% of those whose head circumference was in the “normal” range at birth developed neurologic problems. Those whose head circumference was at the upper end of this range were significantly less likely to have abnormalities than those at the lower end.

Just this single measurement offers considerable insight into the risk of developing neurologic problems after Zika exposure. However, notes Dr. Mulkey, head circumference growth trajectory is also key. Of the 162 infants whose heads were initially in the normocephalic range at birth, about 10.5% went on to develop microcephaly in the months after birth.

“Because early head growth trajectory is associated with cognitive outcomes in early childhood,” Dr. Mulkey writes, “following the head circumference percentile over time can enable recognition of a child with increased risk for poor outcome who could benefit from early intervention therapies.”

This simple assessment could be significantly augmented with neuroimaging, she adds. The study by Cranston et al., as well as others in the field, have shown that brain imaging often reveals problems in ZIKV-exposed children, such as calcifications and cerebral atrophy, even in those with normal head circumferences. This imaging doesn’t necessarily need to take place at birth, Dr. Mulkey says. Postnatal development of microcephaly, failure to thrive or developmental delay can all be triggers for imaging later on.

Together, Dr. Mulkey says, the study by Cranston et al. and others that focus on ZIKV-exposed children support the need for following these patients long term. Children exposed to ZIKV in the epidemic nearly five years ago are now approaching school age, a time fraught with more complicated cognitive and social demands. Through her own research at Children’s National’s Congenital Zika Virus Program and collaboration with colleagues in Colombia, Dr. Mulkey is following multiple cohorts of ZIKV exposed children as they grow. She recently published a study on neurological abnormalities in one of these cohorts in JAMA Pediatrics in January 2020.

“It’s really important to follow these children as long as possible so we’ll really know the outcomes of this virus,” Dr. Mulkey says.

Children’s National ranked a top 10 children’s hospital and No. 1 in newborn care nationally by U.S. News

US News Badges

Children’s National Hospital in Washington, D.C., was ranked No. 7 nationally in the U.S. News & World Report 2020-21 Best Children’s Hospitals annual rankings. This marks the fourth straight year Children’s National has made the list, which ranks the top 10 children’s hospitals nationwide.

In addition, its neonatology program, which provides newborn intensive care, ranked No.1 among all children’s hospitals for the fourth year in a row.

For the tenth straight year, Children’s National also ranked in all 10 specialty services, with seven specialties ranked in the top 10.

“Our number one goal is to provide the best care possible to children. Being recognized by U.S. News as one of the best hospitals reflects the strength that comes from putting children and their families first, and we are truly honored,” says Kurt Newman, M.D., president and CEO of Children’s National Hospital.

“This year, the news is especially meaningful, because our teams — like those at hospitals across the country — faced enormous challenges and worked heroically through a global pandemic to deliver excellent care.”

“Even in the midst of a pandemic, children have healthcare needs ranging from routine vaccinations to life-saving surgery and chemotherapy,” said Ben Harder, managing editor and chief of Health Analysis at U.S. News. “The Best Children’s Hospitals rankings are designed to help parents find quality medical care for a sick child and inform families’ conversations with pediatricians.”

The annual rankings are the most comprehensive source of quality-related information on U.S. pediatric hospitals. The rankings recognize the nation’s top 50 pediatric hospitals based on a scoring system developed by U.S. News. The top 10 scorers are awarded a distinction called the Honor Roll.

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.

Below are links to the seven Children’s National specialty services that U.S. News ranked in the top 10 nationally:

The other three specialties ranked among the top 50 were cardiology and heart surgery, gastroenterology and gastro-intestinal surgery, and urology.
