A new study from Children’s National Hospital reveals how a minimally invasive procedure is transforming care for infants with hemimegalencephaly and medically refractory seizures, offering seizure relief with fewer surgical risks.

Until recently, families of infants with hemimegalencephaly and medically refractory seizures had few treatment options, almost all involved major brain surgery such as hemispherectomy, to remove or disconnect the affected portion of the brain. These procedures, while sometimes effective, carry high risks in very young infants due to the fragility of their developing brains and invasive nature of the surgery.

Now, specialists from the Hemimegalencephaly Program at Children’s National Hospital have pioneered a minimally invasive alternative. Leveraging the combined expertise of a multidisciplinary team — spanning neurology, neurointerventional radiology, prenatal pediatrics, neonatology, neurogenetics and neurodevelopmental pediatrics, neuropsychology and neurosurgery — they have developed a technique that induces controlled, targeted strokes in the affected hemisphere using transarterial embolization (TAE). This approach mimics the effect of surgery by reducing seizure activity, without the need for open brain procedures.

This novel strategy is the focus of a new study led by Monica Pearl, MD, director of the Neurointerventional Radiology Program. The research represents the largest retrospective review of its kind, examining 41 TAE procedures performed over an 11-year span in 13 infants under three months of age.

The results are promising: 73% of patients achieved Engel Class I seizure outcomes at follow-up, suggesting that with careful technique and patient selection, TAE may provide meaningful seizure control with fewer perioperative risks than traditional surgery. The study also highlights the technical complexity of the procedure, early complications and the critical role of evolving protocols in ensuring patient safety.

Authors from Children’s National include Monica Pearl, MD, Tayyba Anwar, MD, Shani Israel, BS, Lindsay Ruffini, CPNP, CPNP-AC, CPNP-PC, Panagiotis Kratimenos, MD, PhD, Kyle Spagnolo, DO, Wei-Liang Chen, MD, Madison Berl, PhD, William D. Gaillard, MD, Tammy N. Tsuchida, MD, PhD and Chima Oluigbo, MD

New study finds prenatal opioid exposure linked to smaller newborn brain volumes

brain scans of newbornA new study out of the Center for Prenatal, Neonatal & Maternal Health Research, directed by Catherine Limperopoulos, PhD, led by Yao Wu, PhD and Stephanie Merhar, MD, MS, out of Cincinnati Children’s Hospital Medical Center, sought answers to the question: “Do brain volumes differ in opioid-exposed vs. unexposed newborns?” In one of the largest studies of this kind, researchers found that prenatal exposure to opioids is associated with smaller brain volumes in newborns. These findings from the landmark Outcomes of Babies with Opioid Exposure (OBOE) study build on, reinforce smaller studies, and achieve a better understanding of the impacts of prenatal opioid exposure (POE).

Dive Deeper

The Advancing Clinical Trials in Neonatal Opioid Withdrawal (ACT-NOW)’s OBOE study is a multi-site observational study of newborns with prenatal opioid exposure and a control group of unexposed newborns from four different sites in the United States – Case Western Reserve University, Cincinnati Children’s Hospital Medical Center, University of Alabama at Birmingham, and Children’s Hospital of Philadelphia.

In a study involving 173 newborns who were exposed to opioids during pregnancy and 96 newborns not exposed to opioids prenatally showed smaller brain sizes in several key areas. Specifically, these exposed babies had smaller total brain volumes, as shown through MRI, as well as reduced volumes in important parts of the brain, including the cortex (outer layer of the brain), deep gray matter (areas that control movement and emotions), white matter (which helps transmit signals in the brain), cerebellum (responsible for coordination and movement), brainstem (controls basic functions like breathing), and the amygdala (involved in emotions and memory).

Further details showed that newborns exposed to medication for opioid use disorder (MOUD) during pregnancy with methadone, had smaller white matter volumes, while those exposed to MOUD with buprenorphine had smaller volumes specifically in the right amygdala. Additionally, newborns who were exposed to opioids plus additional substances such as THC and gabapentin had smaller volumes in even more brain areas compared to those who were only exposed to opioids.

What’s Next

The OBOE study sets the groundwork for further research into the long-term impact of opioid exposure during pregnancy. Additional work is necessary to expand on these findings and how they relate to functions in childhood – including exploring the way these reduced brain volumes may impact cognitive, behavioral, and motor impairments. The study raises important questions about how current guidelines for MOUD during pregnancy – specifically with methadone and buprenorphine – might evolve considering these findings. This study highlights the need for further research to assess the long-term effects of MOUD regimens on both maternal and infant outcomes.

This significant study underscores the importance of multi-disciplinary collaboration in opioid exposure research, effective regulation, and policy interventions – involving healthcare providers, researchers, policymakers, and affected families – to best mitigate the consequences and improve the health outcomes of children affected by prenatal opioid exposure.

Fetal detection, risk stratified care algorithms give infants with CHD their best chance to thrive

Mary Donofrio, M.D., medical director of Prenatal Cardiology at Children’s National Hospital

Mary Donofrio, MD, medical director of Prenatal Cardiology at Children’s National, and other dedicated pediatric cardiologists working in this evolving specialty have spent most of the last two decades defining the field.

Congenital heart disease (CHD) can be detected in utero with precision and accuracy. With advanced technology, identification of a problem happens earlier than ever, including identifying details that predict whether a baby may be dangerously sick at birth. This gives fetal and pediatric cardiologists time to make plans for delivery and specialized care immediately after birth. These critical first moments can be the key to survival for infants with the most complicated defects.

Mary Donofrio, MD, medical director of Prenatal Cardiology at Children’s National Hospital, and other dedicated pediatric cardiologists working in this evolving specialty have spent most of the last two decades defining the field and demonstrating the importance of making sure every child with a congenital heart defect is diagnosed as early as possible to give them the best chance for a healthy life.

Children’s National leads the way

Children’s National performs more than 4,000 fetal ultrasounds each year to detect and manage the unborn child with congenital heart disease, making it one of the most experienced centers in the United States at finding these conditions and planning for their care.

For more than 20 years, every fetus diagnosed with congenital heart disease at Children’s National following an obstetrician referral has their anticipated level of delivery room care assigned by a fetal cardiologist. Protocols were created at Children’s National and validated to establish specialized delivery room management for each patient. The management plan includes specifics about the time and place of delivery and which delivery room staff members are required for stabilization and care after birth based on the severity of the condition.

The outcomes from this approach were published in a landmark 2013 study showing the impact on improving outcomes for infants with the most serious forms of congenital heart disease. Since then, these protocols have become part of more extensive fetal cardiology care guidelines that are in use both at Children’s National and around the world.

“The guidelines we wrote include recommendations about who should get a fetal echo, how to do a fetal echo, how to manage babies in utero including when a fetal intervention might be necessary, and finally how to decide the level of cardiology care that should be present in the delivery room,” according to Donofrio, who served as lead author.

In Washington, D.C., approximately 60 to 75% of congenital heart defects are diagnosed before a baby is born, giving doctors and other care providers critical days, weeks and months to plan how best to protect the fragile infant during their transition into the world from the safe haven of their mother’s body.

What’s next

Fetal imaging guidelines tell obstetricians which expecting mothers should be referred for a fetal ultrasound given a higher level of risk for CHD over the population risk. However, most women do not have any risk factors that will trigger additional testing beyond obstetrical screening. Also, many families even if referred are far from a center that is qualified to perform a fetal echocardiogram to detect these conditions.

Research at Children’s National, led by Anita Krishan, MD, and Dr. Donofrio in collaboration with the Fetal Heart Society, an international research collaborative, showed that in the U.S., factors such as socio-economic status, ethnicity and geography are important barriers to detection of severe congenital heart diseases such as hypoplastic left heart syndrome and transposition of the great arteries.

In a follow-up study by Jennifer Klein, MD, and Dr. Krishnan, distance was not the only barrier to detecting CHD, however. Geo-mapping technology using zip codes allowed the team at Children’s National to pinpoint “hot spots” where detection is decreased, even in places where care should be available. The Heart Center team is hoping to work with providers in these neighborhoods to improve access to care and help educate local clinic providers about how to image and when to refer for further testing.

Donofrio and colleagues are also working to develop ways to improve the diagnosis of fetal heart disease in places that are far from the Heart Center. This includes exploring more portable diagnostic tools and applying telehealth strategies to connect fetal heart experts with local care providers to make an action plan, before a baby arrives potentially in distress. In addition, a phone-based application is under development to help sonographers to identify abnormal images in real time during routine scans in remote locations. Improved detection rates have also opened the doors to powerful new studies investigating how maternal health and stress impacts brain development in fetuses with congenital heart disease. Ongoing research looks at ways to better support expecting mothers, with the goal of helping moms cope with stress during pregnancy so her baby has the best chance possible to be born healthy and strong.

Donofrio says she won’t stop until in utero detection of congenital heart disease is 100%. “Where you live, your neighborhood, your life experience or how far you live from the Heart Center, should not decrease our ability to do everything possible to care for every baby and achieve the best outcome possible,” she says.

Neighborhood disadvantage alters brain networks in unborn babies

Illustration of high and low brain efficiencyGrowing up in a disadvantaged neighborhood changes a child’s brain even before birth. These new findings, in the latest edition of The Journal of Pediatrics, underscore the need to support young families from a baby’s earliest days.

According to this new research from the Center for Prenatal, Neonatal & Maternal Health Research at Children’s National Hospital, exposure to neighborhood disadvantage lessens the functional integration of neural networks in the fetal brain, as seen on functional MRIs of healthy babies. The center compared the brains of 68 healthy babies on 79 scans. Researchers then mapped details about neural activity to a “social vulnerability index” from the Centers for Disease Control and Prevention, which indicates proximity to environmental stressors.

“We specifically looked at brain architecture to see how easily information flows between different regions,” said Kevin Cook, Ph.D., research faculty at the center and the manuscript’s first author. “To do this, we used graph theory, which borrows concepts from social network theory. It’s widely applied in computer science to understand how information flows within groups, and neuroscience has adapted it to study how information travels within the brain.”

What we found

Dr. Cook said researchers focused on the three metrics:

  • Path length, which measures how many stops information needs to make along its way through the brain.
  • Global efficiency, which measures the overall efficiency of the entire brain’s network.
  • Small-world propensity, which describes how the brain’s network is organized and indicates how well the brain is organized into smaller, efficient networks.

As social vulnerability increased, the research team found global efficiency decreased, meaning the brain’s neural network was less efficient. The path lengths were also longer in children with greater neighborhood disadvantage, reinforcing the global efficiency findings.

The fine print

The under-development and over-development of fetal brains may contribute to neurological disorders, such as autism, epilepsy and other conditions of interest to researchers. Yet science’s understanding of how the brain matures in utero is still limited.

In this study, researchers found a notable difference related to age. At the youngest gestational ages, path lengths are longer, and both global efficiency and small world propensity are lower. As the fetus gets closer to term, path length and global efficiency show rapid maturation and less advantaged fetuses catch up to their peers who have greater advantages.

Researchers saw the same findings for small-world propensity, but the maturation didn’t stop. These unborn babies overshot their peers and had greater small-world propensity, suggesting their brains are divided into a greater number of smaller networks than their advantaged peers.

“We believe that length and global efficiency are on a trend to overshoot,” Dr. Cook said. “These findings are notable because they agree with what we know about older children and adolescents. Greater disadvantage is associated with hyper- or over-maturation of the brain. Our findings suggest that this may be starting even before birth.”

What’s ahead

While still early, this research improves the understanding of how environmental complexities can impact an unborn baby. Catherine Limperopoulos, Ph.D., director of the research center, which opened in 2023, said this work will be foundational as they continue to study the impact of a child’s environment on development.

“These findings have important implications for understanding how status and disadvantage may have a cumulative effect on fetal brain development,” Dr. Limperopoulos said. “We must study and consider how to conceptualize the impact of socioenvironmental disadvantage in communities to better care for children and work to improve outcomes.”

Children’s National again ranked among the best in the nation by U.S. News & World Report

2024-25 US News BadgesChildren’s National Hospital in Washington, D.C., was ranked as a top hospital in the nation by the U.S. News & World Report 2024-25 Best Children’s Hospitals annual rankings. This marks the eighth 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.

This year, U.S. News ended ordinal rankings on its Honor Roll. Instead of assigning a numerical rank from 1 to 10, all hospitals on the Honor Roll will be recognized as having attained the highest standards of care in the nation.

In addition, Children’s National tied for #1 pediatric hospital in the Mid-Atlantic region, which includes New York, New Jersey, Delaware, Pennsylvania, the District of Columbia, West Virginia and Virginia. It’s also best in the Mid-Atlantic in Neonatology.

For the fourteenth straight year, Children’s National ranked in 10 specialty services. New this year, U.S. News included behavioral health as a service line in the rankings. Since it’s the first year, there are no ordinal rankings for behavioral health, but the Children’s National program was named one of the top 50 programs in the country.

“In my first year here, I witnessed what makes Children’s National so special — our commitment to collaboration, empowering one another, and charting a bold path forward for pediatric care,” said Michelle Riley-Brown, MHA, FACHE, president and chief executive officer of Children’s National. “I’m proud U.S. News again recognized Children’s National as one of the top in the nation and the highest-ranked pediatric hospital in D.C., Maryland and Virginia. Together, we’ll continue to push the boundaries of care, research and innovation to make a difference for those who matter most — the kids.”

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 nearly two decades, U.S. News has published Best Children’s Hospitals to empower the parents and caregivers of children with complex medical needs,” said Ben Harder, chief of health analysis and managing editor at U.S. News. “Children’s hospitals appearing on the U.S. News Honor Roll have a track record of delivering unparalleled 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 Children’s National specialty services that U.S. News ranked in the top 10 nationally are:

The other four specialties ranked among the top 50 are Behavioral Health, Cardiology and Heart Surgery, Pulmonology and Lung Surgery, and Urology.

New philanthropic support from the United Arab Emirates furthers research breakthroughs and care

Visitors from the UAE at Children's National Hospital.

His Highness Sheikh Mohamed bin Zayed Al Nahyan, President of the United Arab Emirates (right) visited Children’s National in September 2024.

Continuing a 30-year partnership that has yielded 82 U.S. patents and countless medical breakthroughs for kids and their families, the Government of the United Arab Emirates (UAE) has strengthened its transformational commitment to Children’s National Hospital with a new $35 million donation focused on prenatal, neonatal and maternal health.

The announcement of the new gift comes after a recent visit to the hospital by His Highness Sheikh Mohamed bin Zayed Al Nahyan, President of the United Arab Emirates (UAE), who met with Emirati families and patients receiving care at Children’s National Hospital.

The investment is the latest chapter of a longstanding philanthropic partnership between the UAE and Children’s National. Each year, more than 100 Emirati families travel to Children’s National for advanced pediatric care and life-saving treatments.

This latest investment will bolster various strategic health initiatives, including within the hospital’s Center for Prenatal, Neonatal & Maternal Health Research and the Zickler Family Prenatal Pediatrics Institute.

Researchers in the Center for Prenatal, Neonatal & Maternal Health Research are focused on the role of perinatal factors — including maternal stress, anxiety and depression — on the developing brain of the child. Studies also are revealing the impact of congenital anomalies such as heart disease and acquired conditions such as maternal infection with COVID-19 or Zika virus. New approaches to prenatal and postnatal care promise to optimize long-term outcomes of many hospitalized babies.

“Children in the Washington, D.C., area and across the world benefit greatly from the breakthroughs that have emerged from the incredible decades-long partnership between the UAE and Children’s National,” said Michelle Riley-Brown, President and CEO of Children’s National. “I am deeply grateful for the UAE’s most recent gift. The contribution will positively impact children and families and support the teams of researchers and specialists who dedicate their lives to developing innovative medical care.”

Key milestones

The UAE helped to establish the Sheikh Zayed Institute for Pediatric Surgical Innovation at Children’s National in 2009. Today, the Sheikh Zayed Institute (SZI) has grown into a world-class, self-sustaining research center receiving more than 80% of its funding from grants and outside sources.

This platform for invention is advancing autonomous, robotic surgery. The institute’s researchers believe pediatric surgical outcomes will improve if the precision and delicacy of a robot are incorporated into procedures such as gallbladder removal. SZI is also propelling the use of artificial intelligence to improve pediatric medicine and expand health equity. One example is a deep learning algorithm that uses hand-held ultrasounds to detect early signs of rheumatic heart disease, which kills nearly 400,000 people worldwide each year.

“The lives and health of countless children and families in the Washington area, in the UAE and around the world have been transformed by our partnership,” said Yousef Al Otaiba, the UAE Ambassador to the United States. “Our continued support promises even more breakthrough innovations in pediatric medicine.”

The UAE also supported the opening of the Children’s National Research & Innovation Campus through a 2019 commitment. The campus represents the first pediatric innovation hub of its kind, where scientists, inventors, caregivers, patients’ families and health authorities come together to advance pediatric health.

The Children’s National Rare Disease Institute and Center for Genetic Medicine Research are two of the teams housed at the campus. Together, they are pioneering care for children in the Washington region and abroad as an international referral site for rare disorders. Two examples of their research endeavors include: next-generation genomic testing to better understand how differences in genetic material can affect human health and identifying biochemical analytes.

The UAE opened a medical office in Washington, D.C., in 1991. Since then, thousands of Emirati patients have visited Children’s National for life-changing care for conditions such as congenital heart disease, neurological disorders and cancer. The hospital is currently treating 40 Emirati patients.

“Having our child treated at Children’s National means accessing specialized pediatric care from a renowned institution dedicated to children’s health,” said Hamad Alnuaimi, an Emirati father of a Children’s National patient. “It provides us with confidence and reassurance that our son is receiving the best possible medical attention from experts who understand and prioritize the unique needs of children. For the UAE to have a strong relationship with Children’s National signifies a valuable connection that enhances pediatric healthcare in our country. This partnership allows us to benefit from advanced treatments, medical innovations, and expertise that might otherwise be inaccessible. It represents a commitment to improving the health and well-being of children through international collaboration.”

Optimized congenital heart care ‘from twinkle to wrinkle’: Q&A with Wayne Franklin

Wayne J. Franklin, M.D., F.A.C.C., recently joined Children’s National Hospital as senior vice president of the Children’s National Heart Center. In that role, he oversees the full spectrum of heart care services which includes comprehensive care, as he puts it, from twinkle — when a child is barely more than a twinkle in their mother’s eye — to wrinkles — or throughout the lifespan.

During his first week, Dr. Franklin answered questions about his vision for the Children’s National Heart Center and told the team more about his clinical and research priorities.

Q: Why did you choose Children’s National?

A: Children’s National has such a long history of caring for the children and families in the community — over 150 years. This is a hospital taking fantastic care of patients now, but also planning for the future and the future of healthcare specifically. And I wanted to be part of that team. We know health care is ever changing and I want to be ahead of that, really providing the best care possible for today’s patients and about how to plan the ideal care for tomorrow’s patients.

I’m also excited to work with Children’s National President and CEO Michelle Riley-Brown. When I worked with her previously, I found out she’s a fantastic leader. I know she’s already started to do amazing things for Children’s National and the community.

Q: What is your vision for Children’s National Heart Center?

A: My vision for the heart center is to organize, coordinate and optimize all the different aspects of caring for children with heart problems.

It’s a complicated process. There’s intensive care in the hospital, ambulatory care in the clinic, acute care and emergency care. One of my roles is to coalesce all of those facets to provide total care for people from the prenatal period through birth and beyond into the teenage years, adulthood and even parenthood and grandparenthood.

I think we’re well-equipped to do that here at Children’s National.

As part of our commitment to providing the best care for patients and their families, we also plan to rely on our patient-family advisory council and our family-centered care approach. We take patient and family concerns to heart and want to continue bringing that information together with our world-class clinical care. That’s how we’ll be sure to provide great outcomes now and down the road.

Q: How is research a part of your vision for the Heart Center?

A: Research is critical to cardiac disease in children, especially in Washington, D.C. I think we’re very fortunate because people here at Children’s National are doing groundbreaking research and we work close to truly great scientific organizations like the George Washington University and the National Institutes of Health. Some of our heart center faculty actually work at the NIH too.

The top centers in the country, including Children’s National, are involved with cutting-edge innovation and research alongside clinical care and a big part of my job is to support these efforts to translate this science and help improve health outcomes for our patients.

Q: Why did you choose to work in the field of pediatric cardiology?  

A: While children with heart problems can become very sick, our advances in cardiac surgery, catheter interventions, cardiac intensive care and anesthesia allow us to work together to make them better reasonably quickly. To be able to provide them that care is really rewarding. Our team can really impact their health for a lifetime.

Q: What research are you, personally, interested in?

A: The research that I’m particularly interested in involves the full gamut of cardiac disease, from single ventricle physiology to pulmonary hypertension to fetal cardiology to women with heart disease. Fortunately, here at Children’s National there is a strong research infrastructure and some fantastic physician scientists.

Q: How did your interest in pediatric cardiology evolve into a specialty in adult congenital heart disease?  

A: When these kids grow up, they become adults with heart disease that is caused by their congenital heart lesions. It’s a different type of heart disease than an age-related heart attack, high cholesterol or stroke. I focused on this area many years ago because there are now more adults with congenital heart disease than children.

Currently, there is a need for more adult congenital heart disease specialists and there will continue to be need for even more in the future. I’m fortunate to join one of the best adult congenital heart programs in the country by coming to Children’s National.

Q: How do you spend your free time when you aren’t here at the hospital?

A: I work a lot but when I get time away from work, I love to spend my it with my family and I’m lucky to have a truly spectacular wife. In December, we’ll celebrate our 20th wedding anniversary and it’s been an extraordinary and exciting ride. We have two wonderful kids, both teenagers. Being a father myself has given me a different perspective about taking care of children throughout their lifetimes.

Q: What’s your favorite Washington, D.C., monument?

A: I always have to go back to the Lincoln Memorial. It was the first monument I saw on an 8th grade trip. I still remember the moment when I first walked up there…you see him. Incredible. He is literally larger than life, it’s just breathtaking. I think I’ll always remember that feeling.

Pandemic stress in pregnant mothers may affect anxiety regions of babies’ brains

stressed pregnant woman

The research from Children’s National Hospital provides mounting evidence that children of the pandemic, even those far too young to understand it, need ongoing assessments of developmental or mental health support later in life.

A critical part of the brain linked to risks for anxiety later in life – the left amygdala – was significantly smaller by volume in babies of mothers who reported stress during the COVID-19 pandemic, according to a new manuscript published in JAMA Network Open.

The right hippocampus, which governs spatial, visual and verbal memories, and the white matter were also reduced in children whose mothers reported stress.

The research from Children’s National Hospital provides mounting evidence that children of the pandemic, even those far too young to understand it, need ongoing assessments of developmental or mental health support later in life.

“Looking ahead, we want to use this information – and studies with similar findings – to empower pregnant mothers to request support to mitigate their stress, especially in the event of another global health crisis,” said Nickie Andescavage, M.D., a neonatologist and principal investigator at the Center for Prenatal, Neonatal & Maternal Health Research. “We also want to make sure babies born during COVID-19 get the services that they need in life if they develop anxiety or other mental health disorders.”

The fine print

Researchers at the center used magnetic resonance imaging (MRI) to compare the brains of 103 babies born between 2014 and 2019 prior to the pandemic to 59 born between 2020 and 2022. Mothers who had COVID-19 or other complications in their pregnancies were excluded. The babies underwent MRI imaging while in utero and again soon after delivery.

The mothers were evaluated for stress and anxiety, using the Spielberger State-Train Anxiety Inventory and other evidence-based scoring measures. Pre-pandemic, 21% of mothers reported elevated symptoms of anxiety; in the pandemic cohort, that number jumped to nearly 62%.

Their babies’ brains were also changed, as regions widely understood to control emotion and anxiety displayed smaller volumes on MRI imaging. Given the global impact of the pandemic and universal reports of mental distress worldwide, the potential impact of these findings may impact an entire generation of children born during the pandemic. The team is just beginning to unravel the medical significance.

What’s next

Catherine Limperopoulos, Ph.D., director of the Center for Prenatal, Neonatal & Maternal Health Research, said understanding the impact of stress is vital in supporting the healthy development of young children. Current studies are underway at her center to tease apart the role of stress in prenatal development and examine its long-term impact on development, including cognition, behavior and mental health.

“We all know that being pregnant can be quite stressful, and there are certain times of collective stress that can provide us windows to understand how the body and mind manage it,” Dr. Limperopoulos said. “At our center, we care deeply about the health of mothers and babies, and our researchers plan to continue investigating the role of stress in development to continue building data to show that mental health must be a greater priority.”

This study – “Prenatal maternal psychological distress during the COVID-19 pandemic and newborn brain development” – was supported by the National Institutes of Health, the Intellectual and Developmental Disabilities Research Center, and the A. James & Alice B. Clark Foundation. You can read the full study in JAMA Network Open.

Adjusting key protein could improve brain function in children with fetal alcohol syndrome

illustration of a neural network

Researchers at Children’s National are testing whether controlling the level of apolipoprotein E could serve as an effective treatment for the poor neurobehavioral outcomes tied to fetal alcohol spectrum disorders.

Reduced levels of a protein – called apolipoprotein E – are responsible for the lifelong cognitive and neurological symptoms in fetal alcohol spectrum disorders (FASD), according to a new study published in the journal Molecular Psychiatry. For the first time, researchers at Children’s National Hospital are testing whether controlling the level of this protein could serve as an effective treatment for the poor neurobehavioral outcomes tied to FASD, which is believed to affect roughly 5% of school-aged children.

Apolipoprotein E is controlled by a gene called APOE, a well-known risk gene for Alzheimer’s disease. It contains the instructions that guide how the connections between neurons in the brain strengthen or weaken over time. This process, known as synaptic plasticity, is crucial for learning and memory formation. In this study, plasma was collected from participants at two sites in Western Ukraine, along with information about drinking behavior reported by their mothers.

What this means 

“In addition to Alzheimer’s risk, we found this gene is also a crucial contributor to cognitive problems in children with FASD,” said Kazue Hashimoto-Torii, Ph.D., a principal investigator at the Center for Neuroscience Research at Children’s National. “The new data shows that we understand the mechanism by which prenatal alcohol exposure causes a decrease of the APOE level in the brain. We will continue this work to help improve our understanding of FASD, hoping to replenish this important protein and improve outcomes for children with these disorders.”

FASD is an umbrella diagnosis for the physical and developmental challenges that face children who are exposed to alcohol in utero, including intellectual disability, delay in motor and language development and other neurological diagnoses. While alcohol alone is problematic to many aspects of development, evidence also suggests that genetic factors play a role. Only 4.3% of children with heavy alcohol exposure develop FASD, and twin studies have revealed that fraternal twins have different FASD outcomes compared to identical twins.

What’s next 

The research team at Children’s National wanted to pinpoint places where genes could play a role and consider therapies. For the first time, researchers found that plasma levels of APOE were reduced in children with FASD, which strongly supports a potential target for therapy. In addition, their genomics study found a variant of APOE increases the risk of cognitive problems in subjects who were prenatally exposed to alcohol, especially those of African ancestry.

“We found that providing a drug that activates the APOE receptor rescued learning deficits and anxiety in pre-clinical models,” said Masaaki Torii, Ph.D., principal investigator at the Center for Neuroscience Research. “The implications offer an exciting glimpse into possible therapies for some of the neurological harms associated with prenatal alcohol exposure and FASD.”

First-of-its-kind study on impacts of Lyme disease in pregnancy and infant development

borrelia bacteria

Lyme disease is caused by the bacterium Borrelia burgdorferi.

Understanding the effects of Lyme disease on the developing fetal brain is essential to ensure timely prenatal and postnatal treatments to protect the fetus and newborn. In response to this need, Children’s National Hospital is leading a pilot study to establish the groundwork needed for a larger study to determine the effect of in utero exposure to Lyme disease on pregnancy and early childhood neurodevelopmental outcomes.

Why it’s important

“Insect-borne illnesses have more than doubled during the last twenty years as a result of multiple factors including environmental changes,” says Sarah Mulkey, M.D., Ph.D., principal investigator of the study and prenatal-neonatal neurologist at Children’s National Hospital. Dr. Mulkey is the Co-Director of the Congenital Infection Program at Children’s National Hospital and has led a long-term child outcome study of the mosquito-borne Zika virus infection in pregnancy and impacts on child neurodevelopment. She is now adding Lyme disease to her work on pregnancy and child outcomes. Lyme disease is transmitted to humans via an infected tick and can be acquired throughout much of the United States. “Very little is known about Lyme disease in pregnancy and if and how it may affect the fetus and impact child neurodevelopment,” said Dr. Mulkey.

This pilot study is funded by the Clinical Trials Network for Lyme and other Tickborne Diseases (CTN), supported by the Steven and Alexandra Cohen Foundation. Roberta DeBiasi, M.D., M.S., division chief of infectious diseases at Children’s National, is a CTN Node Principal Investigator. The study team at Children’s National works closely with members of the CTN as well as other Lyme disease-focused organizations and nonprofits to make sure that the pilot study addresses Lyme disease advocates’ research priorities in a scientifically rigorous way. “This is an important opportunity for us to engage with advocacy groups and others who have been stressing the need for this type of research for decades,” says Meagan Williams, M.S.P.H., C.C.R.C., the senior research coordinator for the study. “We know how important it is to maintain a patient-centered and trauma-sensitive lens in our work with families impacted by Lyme disease during pregnancy. We’ve been working hard to build this study in a way that centers our participants’ lived experiences and focuses on the topics they find important. We’re very grateful to have the support of Lyme disease focused organizations and advocates as we embark on this study because they know and have expressed exactly where the gaps are in the literature. It’s our job to do the work to fill those gaps.”

The big picture

This pilot study aims to build upon existing research, case studies and advocacy to assess developmental and other family impacts of Lyme disease exposure during pregnancy.

Especially as tick season begins in Washington, D.C., and surrounding regions, the investigators are determined to make sure that all eligible people diagnosed with Lyme disease during their pregnancy are aware of the study and have the opportunity to participate. Pregnant volunteers can sign up for participation in the study here.

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:

  • 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.”

School entry neurodevelopmental outcomes of Zika-exposed Colombian children

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.

Prenatal COVID exposure associated with changes in newborn brain

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.”
