Pioneering research center aims to revolutionize prenatal and neonatal health

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

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

Moving the field forward

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

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

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

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

Assembling a team

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

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

Early accolades

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

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

The endovascular embolic hemispherectomy team.

New hemimegalencephaly procedure is all about teamwork

Children’s National experts pioneered a novel approach of inducing strokes to stop seizures and improve neurodevelopmental outcomes in newborns under three months old with hemimegalencephaly (HME). The procedure, called an endovascular embolic hemispherectomy, can be safely used to provide definitive treatment of HME-related epilepsy in neonates and young infants. Monica Pearl, M.D., neurointerventional radiologist, and Panagiotis Kratimenos, M.D., Ph.D., neonatologist, discuss why having a multidisciplinary team skilled at this procedure is the reason we’re the only center in the world capable of providing this treatment.

The history behind the novel hemimegalencephaly procedure

Traditionally, when a baby is diagnosed with hemimegalencephaly (HME), doctors turn to a hemispherectomy at 3 months of age, which involves surgically removing half of a baby’s brain. At Children’s National Hospital, our doctors pioneered the endovascular embolic hemispherectomy, an approach using induced controlled strokes to eliminate the affected part of the brain, halting seizures. Monica Pearl, M.D., neurointerventional radiologist, and Tammy Tsuchida, M.D., Ph.D., neonatal neurologist, talk about this life-changing procedure.

Inducing strokes to better treat babies with hemimegalencephaly

When a family from Texas received a shocking diagnosis for their newborn daughter, they knew there was one place they needed to go – Children’s National Hospital in Washington, D.C. At birth, Angelique was diagnosed with a rare and devastating condition known as hemimegalencephaly (HME) which causes uncontrollable and frequent seizures. Monica Pearl, M.D., neurointerventional radiologist, and the team at Children’s National have pioneered an approach to treat HME, where they induce controlled strokes to eliminate the affected part of the brain, halting seizures in their tracks. They’re the only team in the world doing this work. Angelique’s parents knew the clock was ticking — every day they waited meant irreversible damage to their daughter’s developing brain.

Prenatal COVID exposure associated with changes in newborn brain

pregnant woman talking to doctor

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

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

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

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

The fine print

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

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

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

What’s ahead

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

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

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

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

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

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

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

mother kissing newborn baby

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

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

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

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

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

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

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

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

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

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

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

Q&A with Daniel J. Licht, M.D.: The future of medicine is in light

Daniel J. Licht, M.D.

A pediatric neurologist who specializes in children with congenital heart disease, Dr. Licht initially came to this area of research as he considered ways to ensure children’s brains have adequate oxygen delivery during heart care, preserving neurological health and improving long-term outcomes.

Daniel J. Licht, M.D., joins Children’s National Hospital with a vision: He believes non-invasive devices built using biomedical optics – or instruments using light – can give clinicians invaluable information about how the brain and other organs are functioning.

A pediatric neurologist who specializes in children with congenital heart disease, Dr. Licht initially came to this area of research as he considered ways to ensure children’s brains have adequate oxygen delivery during heart care, preserving neurological health and improving long-term outcomes. He sees countless applications for using the properties of light in pediatric medicine.

Dr. Licht, whose name coincidentally also means “light” in German, is planning to establish a program for biomedical optics at Children’s National, built on the pillars of education, innovation and commercialization. He wants to tap into the resources of the Sheik Zayed Institute of Pediatric Surgical Innovation and expertise across the hospital. He is launching this effort as part of the new Center for Prenatal, Neonatal & Maternal Health Research.

Q: How can light be used diagnostically?

A: I believe that light is truly the future of biomedical devices, especially in children. Light can penetrate human tissues deeply, whether it’s muscle, liver or kidney. For example, you can put a light at the end of an endoscope and someday do virtual biopsies. It’s all a matter of understanding the properties of light, and how to manipulate light to give you the answers that you need. The applications are truly infinite.

Q: What has your initial work in neurology shown?

A: One of the instruments that we have developed can measure cerebral blood flow and quantitatively show the oxygen use of the brain. That’s important because it’s easy to measure oxygen delivery, but it’s hard to balance supply-and-demand without knowing the patient’s unique demand. We now have preclinical data and information from about 500 patients.

In terms of what’s ahead, many therapies today aren’t targeted to the individual, so Johnny’s brain-oxygen demand may not be the same as Sarah’s brain-oxygen demand, even if they both have congenital heart disease. As a patient waits for surgery, we also have found that the brain-oxygen demand increases, but if the demand is not met, this can lead to pre-operative brain injury. This technology could change the whole conversation about the timing of surgery. In addition, we can measure the brain-oxygen demand intraoperatively. We are finding that we can actually define the right perfusion strategy for each patient, rather than making uniform decisions for all patients with a shared diagnosis.

Lastly, beyond the operating room, we can use this technology for countless conditions. It would help with the treatment of almost any disease in the critical care unit, when we are using tools like ECMO (extracorporeal membrane oxygenation, a salvage technique), and we need to monitor a patient’s status. We can also use it to measure intracranial pressure. In very simple terms, if a child with a shunt comes into the emergency room with a headache, we can noninvasively measure the pressure and see how it’s changed without a head CT. We can decide who needs to go to the operating room – and who doesn’t – without radiation.

Q: How did your career bring you to this point?

A: My interest has always been in brain injury and kids with congenital heart disease. Years ago, I started out using MRI because it was the technology that was bright and shiny at the time. I was part of a team that developed an MRI sequence for measuring cerebral blood flow. We made some discoveries that indicated the culprit for brain injury was not the surgeries. Instead, there was something with the babies.

Unfortunately, with MRI, it’s a big, expensive instrument, and you have to take the baby to the machine for a single point-in-time measurement. So I started working with a physicist at the University of Pennsylvania to develop a way to measure the motion of particles, specifically red blood cells, to study cerebral blood flow. We found ways to use light, and this is what I hope to build and commercialize at Children’s National. By the end of my career, I hope to be able to say that we got this into clinical care.

The research team found that patients who are Black and Medicaid-insured patients experienced the greatest disparities in postoperative sepsis, a rare complication in which patients suffer from infection that can cause multi-organ failure.

Evaluating more than 5 million pediatric hospital stays nationwide, researchers found children who are Black, Hispanic or insured with Medicaid face a greater risk of health events after surgeries than white patients, according to a new study published in the journal Pediatrics.

“We looked at the data, and we calculated the risks,” said Kavita Parikh, M.D., MSHS, medical director of Quality & Safety Research, research director of the Division of Hospital Medicine and first author on the multi-institute study. “Despite decades of focus on eliminating medical errors, we know that children continue to suffer substantial harms in hospital settings, and our study highlights where children who are Black, Hispanic or insured with Medicaid are at the greatest risk.”

The big picture

The study analyzed data from more than 5.2 million hospitalizations collected by the 2019 Kids’ Inpatient Database, a national repository of data on hospital stays. It includes a 10% sample of newborns and an 80% sample of other pediatric discharges from 4,000 U.S. hospitals. More than 80% of patients were younger than 1 year of age.

The research team found that patients who are Black and Medicaid-insured patients experienced the greatest disparities in postoperative sepsis, a rare complication in which patients suffer from infection that can cause multi-organ failure. Patients who are Hispanic experienced the greatest disparity in postoperative respiratory failure, a complication that can limit breathing and ventilation.

Plausible factors cited include structural racism in the U.S. healthcare system, clinician bias, insufficient cultural responsiveness, communication barriers and limited access to high-quality healthcare.

What’s ahead

The study – “Disparities in Racial, Ethnic, and Payor Groups for Pediatric Safety Events in U.S. Hospitals” – is foundational in understanding what is happening among pediatric patients. Dr. Parikh said that researchers now must conduct further studies into these alarming disparities and qualitative work to understand drivers, with the action-oriented goal of developing interventions to improve patient safety in the hospital for all children.

“We brought together leaders in pediatric medicine, health policy and public health to analyze this data, and we are committed to taking the next steps to improve outcomes for pediatric patients,” Dr. Parikh said. “It will take more patient-centered work and research, resources and multifaceted strategies to resolve these worrying disparities for our pediatric patients nationwide.”

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

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

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

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

Why we’re excited

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

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

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

Children’s National leads the way

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

Painful NICU procedures change neurological development in preterm babies

baby in the NICU

Premature infants exposed to pain while in the Neonatal Intensive Care Unit (NICU) are at greater risk for motor delays, language deficits and autism, even in the absence of structural brain injuries, according to findings from the new Center for Prenatal, Neonatal & Maternal Health Research at Children’s National Hospital.

Premature infants exposed to pain while in the Neonatal Intensive Care Unit (NICU) are at greater risk for motor delays, language deficits and autism, even in the absence of structural brain injuries, according to findings from the new Center for Prenatal, Neonatal & Maternal Health Research at Children’s National Hospital.

The research sheds light on the potential outcomes of routine medical interventions – such as heel pricks, venipunctures and IV placements – and correlates these skin breaks to changes in neurological connectivity in the preterm infants’ brains. Published in BMC Medicine, the work provides valuable insights about the far-reaching impact of early medical care.

“We know that premature babies are often exposed to repeated medical interventions, light, sound and other stimuli that they would not experience in utero, and we wanted to better understand the long-term effect,” said Kevin Cook, Ph.D., research faculty at the new center and an expert in fetal and neonatal neurology. “Through this study, we can see that early and repeated exposure to pain appears to alter brain development and put children at risk for poor neurodevelopmental outcomes.”

The big picture

Globally, nearly 1 in 10 babies is born preterm, and the Children’s National team was particularly interested in the experience of those born “very” and “extremely” preterm, which is considered any delivery earlier than 32 and 28 weeks of gestation, respectively. While rates of prematurity have been relatively stable, survival rates of these babies have increased remarkably in recent decades, thanks to improved interventions and therapies for preterm infants. Yet neurodevelopmental challenges among these children persist, with noteworthy risks of autism and other neurological deficits.

At Children’s National, researchers are working to understand the mechanism behind those challenges. Given that the late second trimester and the third trimester are critical periods for brain development, the team wanted to study the effects of exposing babies to the world outside the womb early.

The fine print

Dr. Cook and his colleagues collected resting-state functional MRI (fMRI) scans from 148 infants born at least four weeks prematurely, along with 99 infants born full term. The fMRI scans, uniquely suited for studying the resting state of the brain in non-responsive infants, revealed significant hyperconnectivity within the cerebellum, which coordinates muscle activity, and the limbic and paralimbic regions, which govern emotions, motivation and cognitive functions.

Notably, the hyperconnectivity correlated with the number of skin break procedures, including heel pricks, venipunctures and IV placements. When the children returned for developmental evaluations at 18 months, the skin breaks were strongly associated with an increased risk of autism and lower motor and language scores. The toddlers identified at risk for autism had an average of 118 skin breaks, which is significantly more than the average of 65 skin breaks in those who were not at risk.

What’s ahead

Catherine Limperopoulos, Ph.D., director of the Center for Prenatal, Neonatal & Maternal Health Research, said the findings have important implications for understanding how painful NICU procedures can impact long-term outcomes and how physicians conceptualize the risks of care given to preterm babies. She and her team at the center recommend further research into managing pain in premature babies, especially given the limits of current options and the known risk of opioids.

“With this foundational study, we should consider ways to improve pain management for preterm infants and methods to better weigh the interventions used on these incredibly vulnerable patients,” Dr. Limperopoulos said. “Saving their lives is certainly the priority, and the quality of that life should also be forefront of our minds.”

Modified aquapheresis for the smallest patients in intensive care

father touching newborn baby's head

To date, four patients have benefited from modified aquapheresis at Children’s National in both the PICU and the CICU.

The Division of Nephrology at Children’s National Hospital now offers modified aquapheresis for the smallest patients with acute kidney injury or chronic kidney disease in intensive care units. Aadil Kakajiwala, M.D., MSCI, director of Pediatric Acute Kidney Support Therapies, has been the leader in establishing modified aquapheresis at Children’s National. He joined the faculty at Children’s National in 2021 after completing his pediatric nephrology fellowship at the Children’s Hospital of Philadelphia and pediatric critical care medicine fellowship at Children’s National.

To date, four patients have benefited from modified aquapheresis at Children’s National in both the PICU and the CICU. Dialysis equipment designed for adults has filter set volumes as high as 165ml. Since implementing modified aquapheresis, the new equipment’s filter set volume is just 35ml, making it a great option for dialyzing small patients as low as 1.8kg. This limits blood exposure to the patient and overcomes the limitation of obtaining larger vascular access by using a PICC line.

Dr. Kakajiwala looks to continue training nephrologists, intensive care unit providers and staff across the hospital on modified aquapheresis. “This new offering allows us to offer dialysis to our smallest patients. By utilizing modified aquapheresis, we ensure simultaneous removal of waste products along with fluid removal during the therapy,” says Dr. Kakajiwala. He hopes to work on standardizing all forms of renal replacement therapy offered at Children’s National across all care providers.

Perinatal Mood and Anxiety Lab to launch at Children’s National

mother with newborn baby

The hospital has been working for years on improving screenings and support for perinatal mood and anxiety disorders.

Physician researchers at Children’s National Hospital secured a $1.8 million grant from the Agency for Healthcare Research and Quality (AHRQ) that will fund a Perinatal Mood and Anxiety Patient Safety Lab. Neonatologists, pediatric emergency medicine physicians, psychologists, computer scientists and the Perinatal Mood and Anxiety Disorder team from Children’s National will partner with systems engineers at Virginia Tech and Human Factors experts at MedStar Patient Safety Institute to set up a learning lab. The lab will improve mental health screening, referral and treatment of parents and caregivers at the hospital.

The need

“After multi-month admission to our NICU, 45% of parents screen positive for depression. I can’t think of any other disorder or disease that screens positive at 45%. This can’t be ignored,” says Lamia Soghier, M.D. M.Ed., M.B.A., neonatologist and medical director of the Neonatal Intensive Care Unit (NICU) at Children’s National. “Our goal is to provide safe, comprehensive, point-of-care access to mental health services for caregivers of infants treated at our hospital. I can’t think of a better team on the cutting edge that’s qualified to tackle this issue.”

The big picture

The new grant will tackle three major aims:

  • Optimize screening, referral and treatment for postpartum depression in the NICU and the Pediatric Emergency Department (ED).
  • Design and develop a novel software dashboard for real-time tracking of the screening, referral and treatment stages for eligible mothers.
  • Implement new solutions and evaluate latent safety threats related to missed screening, referral or treatment in current and future systems.

Researchers from the Center for Prenatal, Neonatal & Maternal Health Research and population health experts from the Child Health Advocacy Institute at Children’s National will also support this work.

Leading the way

“Children’s National is truly an innovator in this space,” says Dr. Soghier. “There are very few pediatric hospitals working with families to screen for mental health in the NICU, and fewer tackling the problem in the ED. Our team is dedicated to paving this path.”

The hospital has been working for years on improving screenings and support for perinatal mood and anxiety disorders, which was originally made possible by an investment from the A. James & Alice B. Clark Foundation to Children’s National aimed at providing families with greater access to mental health care and community resources. This new AHRQ grant will support the trajectory and goals of this work.

Understanding mechanisms of injury due to prematurity in human cerebellum

Dr. Panagiotis Kratimenos in the lab

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

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

Why the research is unique

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

Why this research matters for critical newborns

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

Documentation of pain assessment after pain management interventions in the NICU

neonate

Timely assessment of pain in neonates continues to be difficult for staff due to high acuity, workload and staffing shortages.

Neonates may experience more than 300 painful procedures and surgeries throughout their hospitalization. A proactive assessment of pain allows the medical team to detect pain early and adequately manage it. At Children’s National, the Neonatal Intensive Care Unit (NICU) team wants to minimize the impact of pain, particularly in preterm nonverbal infants as it has short- and long-term adverse neurodevelopment effects. Smitha Israel, BSN, RN, clinical program coordinator in the Children’s National neonatology department, created a team to increase compliance in pain reassessments and documentation in the NICU using technology to speed up reporting. That compliance increased from 50% to 75% and has been sustained for over two years.

What’s been the hold-up in the field?

Timely assessment of pain in neonates continues to be difficult for staff due to high acuity, workload and staffing shortages. To combat this, Israel’s group partnered with experts from the triggers team to speed up the reporting of pain assessments and to standardize the assessments when administering a pharmacological intervention.

How will this work benefit patients?

This work improves patient care in the NICU by improving pain management and reducing those possible adverse effects in a neonate’s development that pain may contribute to.

How is this work unique?

This study at Children’s National is the first study of pain assessment in the NICU that has shown improvement beyond published rates and has been sustained for six months after implementation.

JAMA Pediatrics editorial: A better approach for newborn screening

The medical community has an opportunity to update its approach to newborn screening (NBS) to be prepared for emerging technological advancements that will help diagnose children with rare diseases from their first weeks of life, according to an editorial from a leading Children’s National Hospital researcher published in JAMA Pediatrics.

“In health care, we are seeing ways in which we can identify more children who have rare diseases even earlier, in the newborn period, rather than waiting for children to develop symptoms or experience irreversible changes,” said Beth Tarini, M.D., M.S., M.B.A., associate director of the Center for Translational Research. “We have continued innovations in screening technology – with more on the way – that can be added to the screening programs overseen by all 50 states. Updating how we approach newborn screening presents an incredible opportunity for doctors and their patient-families.”

Why it matters

Newborn screening happens before the baby leaves the hospital, generally with a prick of the heel to take a small sample of blood to look for several dozen rare, debilitating disorders such as sickle cell disease, congenital hypothyroidism and cystic fibrosis. The current screening system has grown successfully for roughly 60 years and creates a network of state programs. Along the way, researchers have had extensive debates about which disorders to include, based on whether there are treatments and options for patients.

Dr. Tarini, a pediatrician who has done extensive research on NBS and related policies, said that the existing screening programs across all 50 states should be modernized, with federal research support and funding, to create a unified “learning newborn screening system” that derives information from the 4 million babies born each year and provides feedback to the medical community about best practices for babies who are diagnosed with a rare disease or at risk for developing one.

“A new approach will require resources and infrastructure, but as the technology advances, we should change our system to leverage the experience of doctors, patients, and NBS programs across the country,” Dr. Tarini said. “We have the will, the experience and the ability to transform the care for children with rare disease.”
