Special issue of “Neurochemical Research” honors Vittorio Gallo, Ph.D.

Vittorio Gallo

Investigators from around the world penned manuscripts that were assembled in a special issue of “Neurochemical Research” that honors Vittorio Gallo, Ph.D., for his leadership in the field of neural development and regeneration.

At a pivotal moment early in his career, Vittorio Gallo, Ph.D., was accepted to work with Professor Giulio Levi at the Institute for Cell Biology in Rome, a position that leveraged courses Gallo had taken in neurobiology and neurochemistry, and allowed him to work in the top research institute in Italy directed by the Nobel laureate, Professor Rita Levi-Montalcini.

For four years as a student and later as Levi’s collaborator, Gallo focused on amino acid neurotransmitters in the brain and mechanisms of glutamate and GABA release from nerve terminals. Those early years cemented a research focus on glutamate neurotransmission that would lead to a number of pivotal publications and research collaborations that have spanned decades.

Now, investigators from around the world who have worked most closely with Gallo penned tributes in the form of manuscripts that were assembled in a special issue of “Neurochemical Research” that honors Gallo “for his contributions to our understanding of glutamatergic and GABAergic transmission during brain development and to his leadership in the field of neural development and regeneration,” writes guest editor Arne Schousboe, of the University of Copenhagen in Denmark.

“In spite of news headlines about competition in research and many of the negative things we hear about the research world, this shows that research is also able to create a community around us,” says Gallo, chief research officer at Children’s National Hospital and scientific director for the Children’s National Research Institute.

As just one example, he first met Schousboe 44 years ago when Gallo was a 21-year-old mustachioed graduate student.

“Research can really create a sense of community that we carry on from the time we are in training, nurture as we meet our colleagues at periodic conferences, and continue up to the present. Creating community is bi-directional: influencing people and being influenced by people. People were willing to contribute these 17 articles because they value me,” Gallo says. “This is a lot of work for the editor and the people who prepared papers for this special issue.”

In addition to Gallo publishing more than 140 peer-reviewed papers, 30 review articles and book chapters, Schousboe notes a number of Gallo’s accomplishments, including:

  • He helped to develop the cerebellar granule cell cultures as a model system to study how electrical activity and voltage-dependent calcium channels modulate granule neuron development and glutamate release.
  • He developed a biochemical/neuropharmacological assay to monitor the effects of GABA receptor modulators on the activity of GABA chloride channels in living neurons.
  • He and Maria Usowicz used patch-clamp recording and single channel analysis to demonstrate for the first time that astrocytes express glutamate-activated channels that display functional properties similar to neuronal counterparts.
  • He characterized one of the spliced isoforms of the AMPA receptor subunit gene Gria4 and demonstrated that this isoform was highly expressed in the cerebellum.
  • He and his Children’s National colleagues demonstrated that glutamate and GABA regulate oligodendrocyte progenitor cell proliferation and differentiation.
Purkinje cells

Purkinje cells are large neurons located in the cerebellum that are elaborately branched like interlocking tree limbs and represent the only source of output for the entire cerebellar cortex.

Even the image selected to grace the special issue’s cover continues the theme of continuity and leaving behind a legacy. That image of Purkinje cells was created by a young scientist who works in Gallo’s lab, Aaron Sathyanesan, Ph.D. Gallo began his career working on the cerebellum – a region of the brain important for motor control – and now studies with a team of scientists and clinician-scientists Purkinje cells’ role in locomotor adaptive behavior and how that is disrupted after neonatal brain injury.

“These cells are the main players in cerebellar circuitry,” Gallo says. “It’s a meaningful image because goes back to my roots as a graduate student and is also an image that someone produced in my lab early in his career. It’s very meaningful to me that Aaron agreed to provide this image for the cover of the special issue.”

A bronchopulmonary dysplasia primer to guide clinicians and researchers

newborn in incubator

Six months in the writing, the “Bronchopulmonary Dysplasia Primer” published recently by Nature Reviews will be the gold standard review on this topic for years to come.

The term bronchopulmonary dysplasia, or BPD, was first coined in 1967 to describe a chronic lung disease of preterm newborns after treatment with supplemental oxygen via mechanical ventilation in an effort to save their lives. Back then, infants had 50-50 odds of surviving.

In the intervening years, survival has improved and the characteristics of BPD have evolved. Now, BPD is the most common complication of preterm birth for infants born at fewer than 28 weeks’ gestation, as more and more newborns survive premature birth. Hence, the primer.

“The contributing authors are some of the biggest thinkers on this topic,” says Robin H. Steinhorn, M.D., senior vice president, Center for Hospital-Based Specialties, at Children’s National Hospital and author of the section about BPD diagnosis, screening and prevention. “This document will guide clinical education and investigators in the field of BPD. I anticipate this will be the definitive review article on the subject for the next several years.”

Gestational age and low birth weight remain the most potent predictors of BPD. Some 50,000 extremely low gestational age newborns are born each year in the U.S. About 35% will develop some degree of BPD, according to the primer authors.

These newborns are introduced to life outside the womb well before their lungs are ready. Indeed, the pulmonary surfactants needed for normal lung function – a complex mixture of phospholipids that reduce surface tension within the lungs – don’t differentiate until late in pregnancy. Infants who persistently need respiratory support after the 14th day of life are at the highest risk of being diagnosed with BPD at 36 weeks, the coauthors note.

A number of complicating factors can come into play, including maternal diet; fetal exposure to maternal smoking and infection; structural issues such as pre-eclampsia; acute injury from mechanical ventilation and supplemental oxygen; as well as the body’s halting efforts to repair injured, inflamed lung tissue.

“The good news is the number of the smallest and youngest preterm infants who survive extreme preterm birth has steadily increased. Neonatal intensive care units, like our award-winning NICU, now routinely care for babies born at 22 weeks’ gestation,” Dr. Steinhorn says.

Treatment strategies include:

  • Reducing exposure to intubation and ventilation.
  • Leveraging respiratory stimulants, like caffeine.
  • Postnatal steroid therapy.

“Children’s National Hospital is the only center in our immediate region that provides comprehensive care for infants and children with severe BPD,” Dr. Steinhorn adds. “As the population of vulnerable and fragile infants has grown, we have invested in the equipment and the personnel – including at the Hospital for Sick Children Pediatric Center (HSC) – to create a very safe and supportive environment that improves survival and quality of life.”

Some preterm infants spend their first 9 to 10 months of life at Children’s National, and their days are filled with concentrated physical, occupational and speech therapy, as well as music and play therapy to hasten their rehabilitation.

Once their medical condition stabilizes, they transition to HSC to focus more intently on rehabilitation.

“We see HSC as filling a very important role in their care. When our children graduate to HSC, they are going for ongoing care of their lung disease, but also their ongoing rehabilitation. At HSC, they focus on creating the most normal life that we can possibly create and, over time, that is a life free of ventilators and tracheostomy tubes.”

Goss, University of Wisconsin-Madison; Matthew Laughon, The University of North Carolina at Chapel Hill; Jeffrey A. Whitsett and Alan H. Jobe, Cincinnati Children’s Hospital Medical Center; Steven H.

Maternal mental health alters structure and biochemistry of developing fetal brain

Even when pregnant women have uncomplicated pregnancies and high socioeconomic status, when they experience elevated anxiety, stress or depression these prenatal stressors can alter the structure of the developing fetal brain and disrupt its biochemistry, according to Children’s National Hospital research published online Jan. 29, 2020, in JAMA Network Open.

The Children’s National research findings “have enormous scientific, clinical and public health implications,” Charles A. Nelson III, Ph.D.,  Boston Children’s Hospital, writes in a companion editorial.

“Previously we found that 65% of pregnant women who received a diagnosis of fetal congenital heart disease had elevated levels of stress. It’s concerning but not surprising that pregnant women who wonder if their baby will need open heart surgery would feel stress,” says Catherine Limperopoulos, Ph.D., director of the Center for the Developing Brain at Children’s National and the study’s senior author. “In this latest study, we ran the same panel of questionnaires and were surprised to find a high proportion of otherwise healthy pregnant women whose unborn babies are doing well also report high levels of stress.”

Anxiety and depression are the most common mental health problems during pregnancy. To learn more about the implications for the developing fetal brain, the Children’s National research team recruited 119 healthy volunteers with low-risk pregnancies from obstetric clinics in Washington, D.C., from Jan. 1, 2016, to April 17, 2019. The women’s mean age was 34.4 years old. All were high school graduates, 83% were college graduates, and 84% reported professional employment.

The hippocampus plays a central role in memory and behavioral inhibition and contains high concentrations of corticosteroid receptors and, thus, this brain region is sensitive to stress. Credit: JAMA Network Open.

The team performed 193 fetal brain magnetic resonance imaging (MRI) sessions between 24-40 weeks gestation and measured the volume of the total fetal brain as well as the cortical gray matter, white matter, deep gray matter, cerebellum, brainstem and hippocampus volumes. On the same day as their MRI visit, the pregnant women completed validated questionnaires to measure maternal stress, anxiety and depression, answering questions such as “how do you feel right now,” “how do you generally feel” as well as the degree of stressful feelings they experienced the month prior.

Of the pregnant women in the study:

  • 27% tested positive for stress
  • 26% tested positive for anxiety
  • 11% tested positive for depression
  • Maternal anxiety and stress were associated with increased fetal cortical gyrification
  • Elevated maternal depression was associated with decreased creatine and choline levels in the fetal brain
  • Maternal stress scores decreased with increasing gestational age, while anxiety and depression did not

“We report for the first time that maternal psychological distress may be associated with increased fetal local gyrification index in the frontal and temporal lobes,” says Yao Wu, Ph.D., a research associate working with Limperopoulos at Children’s National and the study’s lead author. “We also found an association with left fetal hippocampal volume, with maternal psychological distress selectively stunting the left hippocampal volumetric growth more than the right. And elevated maternal depression was associated with decreased creatine and choline levels in the fetal brain,” Wu adds.

Late in pregnancy – at the time these women were recruited into the cohort study – the fetal brain grows exponentially and key metabolite levels also rise. Creatine facilitates recycling of adenosine triphosphate, the cell’s energy currency. Typically, levels of this metabolite rise, denoting rapid changes and higher cellular maturation; creatine also is known to support cognitive function. Choline levels also typically rise, marking cell membrane turnover as new cells are generated and support memory, mental focus and concentration.

“These women were healthy, and of high socioeconomic status and educational level, leading us to conclude that the prevalence of prenatal maternal psychological distress may be underestimated,” Limperopoulos adds. “While stress is an everyday reality for most of us, this is different because elevated stress during pregnancy can alter fetal brain programming. Our findings underscore the critical need to universally screen all pregnant women for prenatal psychological distress, even young mothers whose pregnancies wouldn’t otherwise raise red flags.”

Stressful pregnancies can leave fingerprint on fetal brain

Catherine Limperopoulos

“We were alarmed by the high percentage of pregnant women with a diagnosis of a major fetal heart problem who tested positive for stress, anxiety and depression,” says Catherine Limperopoulos, Ph.D., director of the Center for the Developing Brain at Children’s National and the study’s corresponding author.

When a diagnosis of fetal congenital heart disease causes pregnant moms to test positive for stress, anxiety and depression, powerful imaging can detect impaired development in key fetal brain regions, according to Children’s National Hospital research published online Jan. 13, 2020, in JAMA Pediatrics.

While additional research is needed, the Children’s National study authors say their unprecedented findings underscore the need for universal screening for psychological distress as a routine part of prenatal care and taking other steps to support stressed-out pregnant women and safeguard their newborns’ developing brains.

“We were alarmed by the high percentage of pregnant women with a diagnosis of a major fetal heart problem who tested positive for stress, anxiety and depression,” says Catherine Limperopoulos, Ph.D., director of the Center for the Developing Brain at Children’s National and the study’s corresponding author. “Equally concerning is how prevalent psychological distress is among pregnant women generally. We report for the first time that this challenging prenatal environment impairs regions of the fetal brain that play a major role in learning, memory, coordination, and social and behavioral development, making it all the more important for us to identify these women early during pregnancy to intervene,” Limperopoulos adds.

Congenital heart disease (CHD), structural problems with the heart, is the most common birth defect. Still, it remains unclear how exposure to maternal stress impacts brain development in fetuses with CHD.

The multidisciplinary study team enrolled 48 women whose unborn fetuses had been diagnosed with CHD and 92 healthy women with uncomplicated pregnancies. Using validated screening tools, they found:

  • 65% of pregnant women expecting a baby with CHD tested positive for stress
  • 27% of women with uncomplicated pregnancies tested positive for stress
  • 44% of pregnant women expecting a baby with CHD tested positive for anxiety
  • 26% of women with uncomplicated pregnancies tested positive for anxiety
  • 29% of pregnant women expecting a baby with CHD tested positive for depression and
  • 9% women with uncomplicated pregnancies tested positive for depression

All told, they performed 223 fetal magnetic resonance imaging sessions for these 140 fetuses between 21 and 40 weeks of gestation. They measured brain volume in cubic centimeters for the total brain as well as volumetric measurements for key regions such as the cerebrum, cerebellum, brainstem, and left and right hippocampus.

Maternal stress and anxiety in the second trimester were associated with smaller left hippocampi and smaller cerebellums only in pregnancies affected by fetal CHD. What’s more, specific regions — the hippocampus head and body and the left cerebellar lobe – were more susceptible to stunted growth. The hippocampus is key to memory and learning, while the cerebellum controls motor coordination and plays a role in social and behavioral development.

The hippocampus is a brain structure that is known to be very sensitive to stress. The timing of the CHD diagnosis may have occurred at a particularly vulnerable time for the developing fetal cerebellum, which grows faster than any other brain structure in the second half of gestation, particularly in the third trimester.

“None of these women had been screened for prenatal depression or anxiety. None of them were taking medications. And none of them had received mental health interventions. In the group of women contending with fetal CHD, 81% had attended college and 75% had professional educations, so this does not appear to be an issue of insufficient resources,” Limperopoulos adds. “It’s critical that we routinely to do these screenings and provide pregnant women with access to interventions to lower their stress levels. Working with our community partners, Children’s National is doing just that to help reduce toxic prenatal stress for both the health of the mother and for the future newborns. We hope this becomes standard practice elsewhere.”

Adds Yao Wu, Ph.D., a research associate working with Limperopoulos at Children’s National and the study’s lead author: “Our next goal is exploring effective prenatal cognitive behavioral interventions to reduce psychological distress felt by pregnant women and improve neurodevelopment in babies with CHD.”

False negatives: Delayed Zika effects in babies who appeared normal at birth

sleeping baby

Colombian infants exposed to Zika virus in the womb showed neurodevelopmental delays as toddlers, despite having “normal” brain imaging and head circumference at birth, a finding that underscores the importance of long-term neurodevelopmental follow-up for Zika-exposed infants.

Colombian infants exposed to Zika virus in the womb showed neurodevelopmental delays as toddlers, despite having “normal” brain imaging and head circumference at birth, a finding that underscores the importance of long-term neurodevelopmental follow-up for Zika-exposed infants, according to a cohort study published online Jan. 6, 2020, in JAMA Pediatrics.

“These infants had no evidence of Zika deficits or microcephaly at birth. Neurodevelopmental deficits, including declines in mobility and social cognition, emerged in their first year of life even as their head circumference remained normal,” says Sarah B. Mulkey, M.D. Ph.D., a fetal/neonatal neurologist at Children’s National Hospital and the study’s first author. “About one-third of these newborns who underwent postnatal head ultrasound had nonspecific imaging results, which we believe are the first published results finding a link between subtle brain injuries and impaired neuromotor development in Zika-exposed children.”

The multi-institutional research group led by Children’s National enrolled pregnant women in Atlántico Department, which hugs the Caribbean coast of Colombia, who had been exposed to Zika, and performed a series of fetal magnetic resonance images (MRI) and ultrasounds as their pregnancies progressed.

Even though their mothers had laboratory-confirmed Zika infections, 77 out of 82 of their offspring were born with no sign of congenital Zika syndrome, a constellation of birth defects that includes severe brain abnormalities, eye problems and congenital contractures, and 70 underwent additional testing of neurodevelopment during infancy. These apparently normal newborns were born between Aug. 1, 2016, and Nov. 30, 2017, at the height of the Zika epidemic, and had normal head circumference.

When they were 4 to 8 months or 9 to 18 months of age, the infants’ neurodevelopment was evaluated using two validated tools, the Warner Initial Developmental Evaluation of Adaptive and Functional Skills (a 50-item test of such skills as self-care, mobility, communication and social cognition) and the Alberta Infant Motor Scale (a motor examination of infants in prone, supine, sitting and standing positions). Some infants were assessed during each time point.

Women participating in the study were highly motivated, with 91% following up with appointments, even if it meant traveling hours by bus. In addition to Children’s National faculty traveling to Colombia to train staff how to administer the screening instruments, videotaped assessments, MRIs and ultrasounds were read, analyzed and scored at Children’s National. According to the study team, the U.S. scoring of Alberta Infant Motor Scale tests administered in Colombia is also unprecedented for a research study and offers the potential of remote scoring of infants’ motor skill maturity in regions of the world where pediatric specialists, like child neurologists, are lacking.

“Normally, neurodevelopment in infants and toddlers continues for years, building a sturdy neural network that they later use to carry out complex neurologic and cognitive functions as children enter school,” Dr. Mulkey adds. “Our findings underscore the recommendations by the Centers for Disease Control and Prevention (CDC) that all infants exposed to Zika in the womb undergo long-term follow-up, providing an opportunity to intervene earlier.”

An accompanying editorial by CDC staffers concurs, saying the study reported “intriguing data” that add “to the growing evidence of the need for long-term follow-up for all children with Zika virus exposure in utero to ensure they receive the recommended clinical evaluations even when no structural defects are identified at birth.”

In addition to Dr. Mulkey, study co-authors include Margarita Arroyave-Wessel, MPH, Dorothy I. Bulas, M.D., chief of Diagnostic Imaging and Radiology, JiJi Jiang, MS, Stephanie Russo, BS, Robert McCarter, ScD, research section head, design and biostatistics,  Adré J. du Plessis, M.B.Ch.B., MPH, chief of the Division of Fetal and Transitional Medicine, and co-Senior Author, Roberta L. DeBiasi, MD, MS, chief of the Division of Pediatric Infectious Diseases, all of Children’s National; Colleen Peyton, PT, DPT, of Northwestern University; Yamil Fourzali, M.D., of Sabbag Radiologos, Barranquilla, Colombia; Michael E. Msall, M.D., of University of Chicago Comer Children’s Hospital; and co-Senior Author, Carlos Cure, M.D., BIOMELab, Barranquilla, Colombia.

Making healthcare innovation for children a priority

Dr. Kurt Newman in front of the capitol building

Recently, Kurt Newman, M.D., president and CEO of Children’s National Hospital, authored an opinion piece for the popular political website, The Hill. In the article, he called upon stakeholders from across the landscape to address the significant innovation gap in children’s healthcare versus adults.

As Chair of the Board of Trustees of the Children’s Hospital Association,  Dr. Newman knows the importance of raising awareness among policy makers at the federal and state level about the healthcare needs of children. Dr. Newman believes that children’s health should be a national priority that is addressed comprehensively. With years of experience as a pediatric surgeon, he is concerned by the major inequities in the advancements of children’s medical devices and technologies versus those for adults. That’s why Children’s National is working to create collaborations, influence policies and facilitate changes that will accelerate the pace of pediatric healthcare innovation for the benefit of children everywhere. One way that the hospital is tackling this challenge is by developing the Children’s National Research & Innovation Campus, which will be the nation’s first innovation campus focused on pediatric research.

Research & Innovation Campus

Children’s National welcomes Virginia Tech to its new campus

Children’s National Hospital and Virginia Tech create formal partnership that includes the launch of a Virginia Tech biomedical research facility within the new Children’s National Research & Innovation Campus.

Children’s National Hospital and Virginia Tech recently announced a formal partnership that will include the launch of a 12,000-square-foot Virginia Tech biomedical research facility within the new Children’s National Research & Innovation Campus. The campus is an expansion of Children’s National that is located on a nearly 12-acre portion of the former Walter Reed Army Medical Center in Washington, D.C. and is set to open its first phase in December 2020. This new collaboration brings together Virginia Tech, a top tier academic research institution, with Children’s National, a U.S. News and World Report top 10 children’s hospital, on what will be the nation’s first innovation campus focused on pediatric research.

Research & Innovation Campus

“Virginia Tech is an ideal partner to help us deliver on what we promised for the Children’s National Research & Innovation Campus – an ecosystem that enables us to accelerate the translation of potential breakthrough discoveries into new treatments and technologies,” says Kurt Newman, M.D., president and CEO, Children’s National. “Our clinical expertise combined with Virginia Tech’s leadership in engineering and technology, and its growing emphasis on biomedical research, will be a significant advance in developing much needed treatment and cures to save children’s lives.”

Earlier this year, Children’s National announced a collaboration with Johnson & Johnson Innovation LLC to launch JLABS @ Washington, DC at the Research & Innovation Campus. The JLABS @ Washington, DC site will be open to pharmaceutical, medical device, consumer and health technology companies that are aiming to advance the development of new drugs, medical devices, precision diagnostics and health technologies, including applications in pediatrics.

“We are proud to welcome Virginia Tech to our historic Walter Reed campus – a campus that is shaping up to host some of the top minds, talent and innovation incubators in the world,” says Washington, D.C. Mayor Muriel Bowser. “The new Children’s National Research & Innovation Campus will exemplify why D.C. is the capital of inclusive innovation – because we are a city committed to building the public and private partnerships necessary to drive discoveries, create jobs, promote economic growth and keep D.C. at the forefront of innovation and change.”

Faculty from the Children’s National Research Institute and the Fralin Biomedical Research Institute at Virginia Tech Carilion (VTC) have worked together for more than a decade, already resulting in shared research grants, collaborative publications and shared intellectual property. Together, the two institutions will now expand their collaborations to develop new drugs, medical devices, software applications and other novel treatments for cancer, rare diseases and other disorders.

“Joining with Children’s National in the nation’s capital positions Virginia Tech to improve the health and well-being of infants and children around the world,” says Virginia Tech President Tim Sands, Ph.D. “This partnership resonates with our land-grant mission to solve big problems and create new opportunities in Virginia and D.C. through education, technology and research.”

The partnership with Children’s National adds to Virginia Tech’s growing footprint in the Washington D.C. region, which includes plans for a new graduate campus in Alexandria, Va. with a human-centered approach to technological innovation. Sands said the proximity of the two locations – just across the Potomac – will enable researchers to leverage resources, and will also create opportunities with the Virginia Tech campus in Blacksburg, Va. and the Virginia Tech Carilion Health Science and Technology campus in Roanoke, Va.

Carilion Clinic and Children’s National have an existing collaboration for provision of certain specialized pediatric clinical services. The more formalized partnership between Virginia Tech and Children’s National will drive the already strong Virginia Tech-Carilion Clinic partnership, particularly for children’s health initiatives and facilitate collaborations between all three institutions in the pediatric research and clinical service domains.

Children’s National and Virginia Tech will engage in joint faculty recruiting, joint intellectual property, joint training of students and fellows, and collaborative research projects and programs according to Michael Friedlander, Ph.D., Virginia Tech’s vice president for health sciences and technology, and executive director of the Fralin Biomedical Research Institute at VTC.

“The expansion and formalization of our partnership with Children’s National is extremely timely and vital for pediatric research innovation and for translating these innovations into practice to prevent, treat and ultimately cure nervous system cancer in children,” says Friedlander, who has collaborated with Children’s National leaders and researchers for more than 20 years. “Both Virginia Tech and Children’s National have similar values and cultures with a firm commitment to discovery and innovation in the service of society.”

“Brain and other nervous system cancers are among the most common cancers in children (alongside leukemia),” says Friedlander. “With our strength in neurobiology including adult brain cancer research in both humans and companion animals at Virginia Tech and the strength of Children’s National research in pediatric cancer, developmental neuroscience and intellectual disabilities, this is a perfect match.”

The design of the Children’s National Research & Innovation Campus not only makes it conducive for the hospital to strengthen its prestigious partnerships with Virginia Tech and Johnson & Johnson, it also fosters synergies with federal agencies like the Biomedical Advanced Research and Development Authority, which will collaborate with JLABS @ Washington, DC to establish a specialized innovation zone to develop responses to health security threats. As more partners sign on, this convergence of key public and private institutions will accelerate discoveries and bring them to market faster for the benefit of children and adults.

“The Children’s National Research & Innovation Campus pairs an inspirational mission to find new treatments for childhood illness and disease with the ideal environment for early stage companies. I am confident the campus will be a magnet for big ideas and will be an economic boost for Washington DC and the region,” says Jeff Zients, who was appointed chair of the Children’s National Board of Directors effective October 1, 2019. As a CEO and the former director of President Obama’s National Economic Council, Zients says that “When you bring together business, academia, health care and government in the right setting, you create a hotbed for innovation.”

Ranked 7th in National Institutes of Health research funding among pediatric hospitals, Children’s National continues to foster collaborations as it prepares to open its first 158,000-square-foot phase of its Research & Innovation Campus. These key partnerships will enable the hospital to fulfill its mission of keeping children top of mind for healthcare innovation and research while also contributing to Washington D.C.’s thriving innovation economy.

Tailored T-cell therapies neutralize viruses that threaten kids with PID

t-cells

Tailored T-cells specially designed to combat a half dozen viruses are safe and may be effective in preventing and treating multiple viral infections, according to research led by Children’s National Hospital faculty.

Catherine Bollard, M.B.Ch.B., M.D., director of the Center for Cancer and Immunology Research at Children’s National and the study’s senior author, presented the teams’ findings Nov. 8, 2019, during a second-annual symposium jointly held by Children’s National and the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH). Children’s National and NIAID formed a research partnership in 2017 to develop and conduct collaborative clinical research studies focused on young children with allergic, immunologic, infectious and inflammatory diseases. Each year, they co-host a symposium to exchange their latest research findings.

According to the NIH, more than 200 forms of primary immune deficiency diseases impact about 500,000 people in the U.S. These rare, genetic diseases so impair the person’s immune system that they experience repeated and sometimes rare infections that can be life threatening. After a hematopoietic stem cell transplantation, brand new stem cells can rebuild the person’s missing or impaired immune system. However, during the window in which the immune system rebuilds, patients can be vulnerable to a host of viral infections.

Because viral infections can be controlled by T-cells, the body’s infection-fighting white blood cells, the Children’s National first-in-humans Phase 1 dose escalation trial aimed to determine the safety of T-cells with antiviral activity against a half dozen opportunistic viruses: adenovirus, BK virus, cytomegalovirus (CMV), Epstein-Barr virus (EBV), Human Herpesvirus 6 and human parainfluenza-3 (HPIV3).

Eight patients received the hexa-valent, virus-specific T-cells after their stem cell transplants:

  • Three patients were treated for active CMV, and the T-cells resolved their viremia.
  • Two patients treated for active BK virus had complete symptom resolution, while one had hemorrhagic cystitis resolved but had fluctuating viral loads in their blood and urine.
  • Of two patients treated prophylactically, one developed EBV viremia that was treated with rituximab.

Two additional patients received the T-cell treatments under expanded access for emergency treatment, one for disseminated adenoviremia and the other for HPIV3 pneumonia. While these critically ill patients had partial clinical improvement, they were being treated with steroids which may have dampened their antiviral responses.

“These preliminary results show that hexaviral-specific, virus-specific T-cells are safe and may be effective in preventing and treating multiple viral infections,” says Michael Keller, M.D., a pediatric immunologist at Children’s National and the lead study author. “Of note, enzyme-linked immune absorbent spot assays showed evidence of antiviral T-cell activity by three months post infusion in three of four patients who could be evaluated and expansion was detectable in two patients.”

In addition to Drs. Bollard and Keller, additional study authors include Katherine Harris M.D.; Patrick J. Hanley Ph.D., assistant research professor in the Center for Cancer and Immunology; Allistair Abraham, M.D., a blood and marrow transplantation specialist; Blachy J. Dávila Saldaña, M.D., Division of Blood and Marrow Transplantation; Nan Zhang Ph.D.; Gelina Sani BS; Haili Lang MS; Richard Childs M.D.; and Richard Jones M.D.

Novel approach to detect fetal growth restriction

doctor checking pregnant woman's belly

Morphometric and textural analyses of magnetic resonance imaging can point out subtle architectural deviations associated with fetal growth restriction during the second half of pregnancy, a first-time finding that has the promise to lead to earlier intervention.

Morphometric and textural analyses of magnetic resonance imaging (MRI) can point out subtle architectural deviations that are associated with fetal growth restriction (FGR) during the second half of pregnancy. The first-time finding hints at the potential to spot otherwise hidden placental woes earlier and intervene in a more timely fashion, a research team led by Children’s National Hospital faculty reports in Pediatric Research.

“We found reduced placental size, as expected, but also determined that the textural metrics are accelerated in FGR when factoring in gestational age, suggesting premature placental aging in FGR,” says Nickie Andescavage, M.D., a neonatologist at Children’s National and the study’s lead author. “While morphometric and textural features can discriminate placental differences between FGR cases with and without Doppler abnormalities, the pattern of affected features differs between these sub-groups. Of note, placental insufficiency with abnormal Doppler findings have significant differences in the signal-intensity metrics, perhaps related to differences of water content within the placenta.”

The placenta, an organ shared by the pregnant woman and the developing fetus, delivers oxygen and nutrients to the developing fetus and ferries away waste products. Placental insufficiency is characterized by a placenta that develops poorly or is damaged, impairing blood flow, and can result in still birth or death shortly after birth. Surviving infants may be born preterm or suffer early brain injury; later in life, they may experience cardiovascular, metabolic or neuropsychiatric problems.

Because there are no available tools to help clinicians identify small but critical changes in placental architecture during pregnancy, placental insufficiency often is found after some damage is already done. Typically, it is discovered when FGR is diagnosed, when a fetus weighs less than 9 of 10 fetuses of the same gestational age.

“There is a growing appreciation for the prenatal origin of some neuropsychiatric disorders that manifest years to decades later. Those nine months of gestation very much define the breath of who we later become as adults,” says Catherine Limperopoulos, Ph.D., director of MRI Research of the Developing Brain at Children’s National and the study’s senior author. “By identifying better biomarkers of fetal distress at an earlier stage in pregnancy and refining our imaging toolkit to detect them, we set the stage to be able to intervene earlier and improve children’s overall outcomes.”

The research team studied 32 healthy pregnancies and compared them with 34 pregnancies complicated by FGR. These women underwent up to two MRIs between 20 weeks to 40 weeks gestation. They also had abdominal circumference, fetal head circumference and fetal femur length measured as well as fetal weight estimated.

In pregnancies complicated by FGR, placentas were smaller, thinner and shorter than uncomplicated pregnancies and had decreased placental volume. Ten of 13 textural and morphometric features that differed between the two groups were associated with absolute birth weight.

“Interestingly, when FGR is diagnosed in the second trimester, placental volume, elongation and thickness are significantly reduced compared with healthy pregnancies, whereas the late-onset of FGR only affects placental volume,” Limperopoulos adds. “We believe with early-onset FGR there is a more significant reduction in the developing placental units that is detected by gross measures of size and shape. By the third trimester, the overall shape of the placenta seems to have been well defined so that primarily volume is affected in late-onset FGR.”

In addition to Dr. Andescavage and Limperopoulos, study co-authors include Sonia Dahdouh, Sayali Yewale, Dorothy Bulas, M.D., chief of the Division of Diagnostic Imaging and Radiology, and Biostatistician, Marni Jacobs, Ph.D., MPH, all of Children’s National; Sara Iqbal, of MedStar Washington Hospital Center; and Ahmet Baschat, of Johns Hopkins Center for Fetal Therapy.

Financial support for research described in this post was provided by the National Institutes of Health under award number 1U54HD090257, R01-HL116585, UL1TR000075 and KL2TR000076, and the Clinical-Translational Science Institute-Children’s National.

$5M in federal funding to help patients with urea cycle disorders

Andrea Gropman

Andrea L. Gropman, M.D.: We have collected many years of longitudinal clinical data, but with this new funding now we can answer questions about these diseases that are meaningful on a day-to-day basis for patients with urea cycle disorders.

An international research consortium co-led by Andrea L. Gropman, M.D., at Children’s National Hospital has received $5 million in federal funding as part of an overall effort to better understand rare diseases and accelerate potential treatments to patients.

Urea cycle disorder, one such rare disease, is a hiccup in a series of biochemical reactions that transform nitrogen into a non-toxic compound, urea. The six enzymes and two carrier/transport molecules that accomplish this essential task reside primarily in the liver and, to a lesser degree, in other organs.

The majority of patients have the recessive form of the disorder, meaning it has skipped a generation. These kids inherit one copy of an abnormal gene from each parent, while the parents themselves were not affected, says Dr. Gropman, chief of the Division of Neurodevelopmental Pediatrics and Neurogenetics at Children’s National. Another more common version of the disease is carried on the X chromosome and affects boys more seriously that girls, given that boys have only one X chromosome.

Regardless of the type of urea cycle disorder, when the urea cycle breaks down, nitrogen converts into toxic ammonia that builds up in the body (hyperammonemia), particularly in the brain. As a result, the person may feel lethargic; if the ammonia in the bloodstream reaches the brain in high concentrations, the person can experience seizures, behavior changes and lapse into a coma.

Improvements in clinical care and the advent of effective medicines have transformed this once deadly disease into a more manageable chronic ailment.

“It’s gratifying that patients diagnosed with urea cycle disorder now are surviving, growing up, becoming young adults and starting families themselves. Twenty to 30 years ago, this never would have seemed conceivable,” Dr. Gropman says. “We have collected many years of longitudinal clinical data, but with this new funding now we can answer questions about these diseases that are meaningful on a day-to-day basis for patients with urea cycle disorders.”

In early October 2019, the National Institutes of Health (NIH) awarded the Urea Cycle Disorders Consortium for which Dr. Gropman is co-principal investigator a five-year grant. This is the fourth time that the international Consortium of physicians, scientists, neuropsychologists, nurses, genetic counselors and researchers has received NIH funding to study this group of conditions.

Dr. Gropman says the current urea cycle research program builds on a sturdy foundation built by previous principal investigators Mendel Tuchman, M.D., and Mark Batshaw, M.D., also funded by the NIH. While previous rounds of NIH funding powered research about patients’ long-term survival prospects and cognitive dysfunction, this next phase of research will explore patients’ long-term health.

Among the topics they will study:

Long-term organ damage. Magnetic resonance elastrography (MRE) is a state-of-the-art imaging technique that combines the sharp images from MRI with a visual map that shows body tissue stiffness. The research team will use MRE to look for early changes in the liver – before patients show any symptoms – that could be associated with long-term health impacts. Their aim is spot the earliest signs of potential liver dysfunction in order to intervene before the patient develops liver fibrosis.

Academic achievement. The research team will examine gaps in academic achievement for patients who appear to be underperforming to determine what is triggering the discrepancy between their potential and actual scholastics. If they uncover issues such as learning difficulties or mental health concerns like anxiety, there are opportunities to intervene to boost academic achievement.

“And if we find many of the patients meet the criteria for depression or anxiety disorders, there are potential opportunities to intervene.  It’s tricky: We need to balance their existing medications with any new ones to ensure that we don’t increase their hyperammonemia risk,” Dr. Gropman explains.

Neurologic complications. The researchers will tap continuous, bedside electroencephalogram, which measures the brain’s electrical activity, to detect silent seizures and otherwise undetectable changes in the brain in an effort to stave off epilepsy, a brain disorder that causes seizures.

“This is really the first time we will examine babies’ brains,” she adds. “Our previous imaging studies looked at kids and adults who were 6 years and older. Now, we’re lowering that age range down to infants. By tracking such images over time, the field has described the trajectory of what normal brain development should look like. We can use that as a background and comparison point.”

In the future, newborns may be screened for urea cycle disorder shortly after birth. Because it is not possible to diagnose it in the womb in cases where there is no family history, the team aims to better counsel families contemplating pregnancy about their possible risks.

Research described in this post was underwritten by the NIH through its Rare Diseases Clinical Research Network.

allopregnanolone molecule

Autism spectrum disorder risk linked to insufficient placental steroid

allopregnanolone molecule

A study led by Children’s National Hospital and presented during Neuroscience 2019 finds that loss of allopregnanolone, a key hormone supplied by the placenta, leads to long-term structural alterations of the cerebellum – a brain region essential for smooth motor coordination, balance and social cognition – and increases the risk of developing autism.

An experimental model study suggests that allopregnanolone, one of many hormones produced by the placenta during pregnancy, is so essential to normal fetal brain development that when provision of that hormone decreases – as occurs with premature birth – offspring are more likely to develop autism-like behaviors, a Children’s National Hospital research team reports at the Neuroscience 2019 annual meeting.

“To our knowledge, no other research team has studied how placental allopregnanolone (ALLO) contributes to brain development and long-term behaviors,” says Claire-Marie Vacher, Ph.D., lead author. “Our study finds that targeted loss of ALLO in the womb leads to long-term structural alterations of the cerebellum – a brain region that is essential for motor coordination, balance and social cognition ­– and increases the risk of developing autism,” Vacher says.

According to the Centers for Disease Control and Prevention, about 1 in 10 infants is born preterm, before 37 weeks gestation; and 1 in 59 children has autism spectrum disorder.

In addition to presenting the abstract, on Monday, Oct. 21, Anna Penn, M.D., Ph.D., the abstract’s senior author, will discuss the research with reporters during a Neuroscience 2019 news conference. This Children’s National abstract is among 14,000 abstracts submitted for the meeting, the world’s largest source of emerging news about brain science and health.

ALLO production by the placenta rises in the second trimester of pregnancy, and levels of the neurosteroid peak as fetuses approach full term.

To investigate what happens when ALLO supplies are disrupted, a research team led by Children’s National created a novel transgenic preclinical model in which they deleted a gene essential in ALLO synthesis. When production of ALLO in the placentas of these experimental models declines, offspring had permanent neurodevelopmental changes in a sex- and region-specific manner.

“From a structural perspective, the most pronounced cerebellar abnormalities appeared in the cerebellum’s white matter,” Vacher adds. “We found increased thickness of the myelin, a lipid-rich insulating layer that protects nerve fibers. From a behavioral perspective, male offspring whose ALLO supply was abruptly reduced exhibited increased repetitive behavior and sociability deficits – two hallmarks in humans of autism spectrum disorder.”

On a positive note, providing a single ALLO injection during pregnancy was enough to avert both the cerebellar abnormalities and the aberrant social behaviors.

The research team is now launching a new area of research focus they call “neuroplacentology” to better understand the role of placenta function on fetal and newborn brain development.

“Our team’s data provide exciting new evidence that underscores the importance of placental hormones on shaping and programming the developing fetal brain,” Vacher notes.

Extracting actionable research data faster, with fewer hassles

Mihailo Kaplarevic

Mihailo Kaplarevic, Ph.D., the newly minted Chief Research Information Officer at Children’s National Hospital and Bioinformatics Division Chief at Children’s National Research Institute, will provide computational support, advice, informational guidance, expertise in big data and data analyses for researchers and clinicians.

Kaplarevic’s new job is much like the role he played most recently at the National Heart, Lung and Blood Institute (NHLBI), assembling a team of researchers and scientists skilled in computing and statistical analyses to assist as in-house experts for other researchers and scientists.

NHLBI was the first institute within the National Institutes of Health (NIH) family to set up a scientific information office. During his tenure, a half-dozen other NIH institutions followed, setting up the same entity to help bridge the enormous gap between basic and clinical science and everything related to IT.

“There is a difference compared with traditional IT support at Children’s National – which will remain in place and still do the same sort of things they have been doing so far,” he says of The Bear Institute for Health Innovation. “The difference is this office has experience in research because every single one of us was a researcher at a certain point in our career: We are published. We applied for grants. We lived the life of a typical scientist. On top of that, we’re coming from the computational world. That helps us bridge the gaps between research and clinical worlds and IT.”

Ultimately, he aims to foster groundbreaking science by recognizing the potential to enhance research projects by bringing expertise acquired over his career and powerful computing tools to help teams achieve their goals in a less expensive and more efficient way.

“I have lived the life of a typical scientist. I know exactly how painful and frustrating it can be to want to do something quickly and efficiently but be slowed by technological barriers,” he adds.

As just one example, his office will design the high-performance computing cluster for the hospital to help teams extract more useful clinical and research data with fewer headaches.

Right now, the hospital has three independent clinical systems storing patient data; all serve a different purpose. (And there are also a couple of research information systems, also used for different purposes.) Since databases are his expertise, he will be involved in consolidating data resources, finding the best way to infuse the project with the bigger-picture mission – especially for translational science – and creating meaningful, actionable reports.

“It’s not only about running fewer queries,” he explains. “One needs to know how to design the right question. One needs to know how to design that question in a way that the systems could understand. And, once you get the data back, it’s a big set of things that you need to further filter and carefully shape. Only then will you get the essence that has clinical or scientific value. It’s a long process.”

As he was introduced during a Children’s National Research Institute faculty meeting in late-September 2019, Kaplarevic joked that his move away from pure computer science into a health care and clinical research domain was triggered by his parents: “When my mom would introduce me, she would say ‘My son is a doctor, but not the kind of doctor who helps other people.’ ”

Some of that know-how will play out by applying tools and methodology to analyze big data to pluck out the wheat (useful data) from the chaff in an efficient and useful way. On projects that involve leveraging cloud computing for storing massive amounts of data, it could entail analyzing the data wisely to reduce its size when it comes back from the cloud – when the real storage costs come in. “You can save a lot of money by being smart about how you analyze data,” he says.

While he expects his first few months will be spent getting the lay of the land, understanding research project portfolios, key principal investigators and the pediatric hospital’s biggest users in the computational domain, he has ambitious longer-term goals.

“Three years from now, I would like this institution to say that the researchers are feeling confident that their research is not affected by limitations related to computer science in general. I would like this place to become a very attractive environment for up-and-coming researchers as well as for established researchers because we are offering cutting-edge technological efficiencies; we are following the trends; we are a secure place; and we foster science in the best possible way by making computational services accessible, affordable and reliable.”

Lee Beers

Getting to know Lee Beers, M.D., FAAP, future president-elect of AAP

Lee Beers

Lee Savio Beers, M.D., FAAP, Medical Director of Community Health and Advocacy at the Child Health Advocacy Institute (CHAI) at Children’s National Hospital carved out a Monday morning in late-September 2019, as she knew the American Academy of Pediatrics (AAP) would announce the results of its presidential election, first by telephone call, then by an email to all of its members.  Her husband blocked off the morning as well to wait with her for the results.  She soon got the call that she was elected by her peers to become AAP president-elect, beginning Jan. 1, 2020. Dr. Beers will then serve as AAP president in 2021 for a one-year term.

That day swept by in a rush, and then the next day she was back in clinic, caring for her patients, some of them teenagers whom she had taken care of since birth. Seeing children and families she had known for such a long time, some of whom had complex medical needs, was a perfect reminder of what originally motivated Dr. Beers to be considered as a candidate in the election.

“When we all work together – with our colleagues, other professionals, communities and families – we can make a real difference in the lives of children.  So many people have reached out to share their congratulations, and offer their support or help. There is a real sense of collaboration and commitment to child health,” Dr. Beers says.

That sense of excitement ripples through Children’s National.

“Dr. Beers has devoted her career to helping children. She has developed a national advocacy platform for children. I can think of no better selection for the president-elect role of the AAP. She will be of tremendous service to children within AAP national leadership,” says Kurt Newman, M.D., Children’s National Hospital President and CEO.

AAP comprises 67​,000 pediatricians, and its mission is to promote and safeguard the health and well-being of all children – from infancy to adulthood.

The daughter of a nuclear engineer and a schoolteacher, Dr. Beers knew by age 5 that she would become a doctor. Trained as a chemist, she entered the Emory University School of Medicine after graduation. After completing residency at the Naval Medical Center, she became the only pediatrician assigned to the Guantanamo Bay Naval Station.

That assignment to Cuba, occurring so early in her career, turned out to be a defining moment that shapes how she partners with families and other members of the team to provide comprehensive care.

“I was a brand-new physician, straight out of residency, and was the only pediatrician there so I was responsible for the health of all of the kids on the base. I didn’t know it would be this way at the time, but it was formative. It taught me to take a comprehensive public health approach to taking care of kids and their families,” she recalls.

On the isolated base, where she also ran the immunization clinic and the nursery, she quickly learned she had to judiciously use resources and work together as a team.

“It meant that I had to learn how to lead a multi-disciplinary team and think about how our health care systems support or get in the way of good care,” she says.

One common thread that unites her past and present is helping families build resiliency to shrug off adversity and stress.

“The base was a difficult and isolated place for some families and individuals, so I thought a lot about how to support them. One way is finding strong relationships where you are, which was important for patients and families miles away from their support systems. Another way is to find things you could do that were meaningful to you.”

Cuba sits where the Atlantic Ocean, Caribbean Sea and Gulf of Mexico meet. Dr. Beers learned how to scuba dive there – something she never would have done otherwise – finding it restful and restorative to appreciate the underwater beauty.

“I do think these lessons about resilience are universal. There are actually a lot of similarities between the families I take care of now, many of whom are in socioeconomically vulnerable situations, and military families when you think about the level of stress they are exposed to,” she adds.

Back stateside in 2001, Dr. Beers worked as a staff pediatrician at the National Naval Medical Center in Bethesda, Maryland, and Walter Reed Army Medical Center in Washington, D.C. In 2003, Dr. Beers joined Children’s National Hospital as a general pediatrician in the Goldberg Center for Community Pediatric Health. Currently, she oversees the DC Collaborative for Mental Health in Pediatric Primary Care, a public-private coalition that elevates the standards of mental health care for all children, and is Co-Director of the Early Childhood Innovation Network. She received the Academic Pediatric Association’s 2019 Public Policy and Advocacy Award.

As a candidate, Dr. Beers pledged to continue AAP’s advocacy and public policy efforts and to further enhance membership diversity and inclusion. Among her signature issues:

  • Partnering with patients, families, communities, mental health providers and pediatricians to co-design systems to bolster children’s resiliency and to alleviate growing pediatric mental health concerns
  • Tackling physician burnout by supporting pediatricians through office-based education and systems reforms
  • Expanding community-based prevention and treatment

“I am humbled and honored to have the support of my peers in taking on this newest leadership role,” says Dr. Beers. “AAP has been a part of my life since I first became a pediatrician, and my many leadership roles in the DC chapter and national AAP have given me a glimpse of the collective good that pediatricians can accomplish by working together toward common strategic goals.”

AAP isn’t just an integral part of her life, it’s where she met her future husband, Nathaniel Beers, M.D., MPA, FAAP, President of The HSC Health Care System. The couple’s children regularly attended AAP meetings with them when they were young.

Just take a glimpse at Lee Beers’ Twitter news feed. There’s a steady stream of images of her jogging before AAP meetings to amazing sunrises, jogging after AAP meetings to stellar sunsets and always, always, images of the entire family, once collectively costumed as The Incredibles.

“I really do believe that we have to set an example: If we are talking about supporting children and families in our work, we have to set that example in our own lives. That looks different for everyone, but as pediatricians and health professionals, we can model prioritizing our families while still being committed to our work,” she explains.

“Being together in the midst of the craziness is just part of what we do as a family. We travel a lot, and our kids have gone with us to AAP meetings since they were infants. My husband even brought our infant son to a meeting at the mayor’s office when he was on paternity leave. Recognizing that not everyone is in a position to be able to do things like that, it’s important for us to do it – to continue to change the conversation and make it normal to have your family to be part of your whole life, not have a separate work life and a separate family life.”

Paradoxical outcomes for Zika-exposed tots

In the midst of an unprecedented Zika crisis in Brazil, there were a few flickers of hope: Some babies appeared to be normal at birth, free of devastating birth defects that affected other Brazilian children exposed to the virus in utero.

In the midst of an unprecedented Zika crisis in Brazil, there were a few flickers of hope: Some babies appeared to be normal at birth, free of devastating birth defects that affected other Brazilian children exposed to the virus in utero. But according to a study published online July 8, 2019, in Nature Medicine and an accompanying commentary co-written by a Children’s National clinician-researcher, the reality for Zika-exposed infants is much more complicated.

Study authors led by Karin Nielsen-Saines at David Geffen UCLA School of Medicine followed 216 infants in Rio de Janeiro who had been exposed to the Zika virus during pregnancy, performing neurodevelopmental testing when the babies ranged in age from 7 to 32 months. These infants’ mothers had had Zika-related symptoms themselves, including rash.

Although many children had normal assessments, 29% scored below average in at least one domain of neurological development, including cognitive performance, fine and gross motor skills and expressive language, Sarah B. Mulkey, M.D., Ph.D., and a colleague write in a companion commentary published online by Nature Medicine July 29, 2019.

The study authors found progressively higher risks for developmental, hearing and eye abnormality depending on how early the pregnancy was at the time the infants were exposed. Because Zika virus has an affinity for immature neurons, even babies who were not born with microcephaly remained at continued risk for suffering abnormalities.

Of note, 24 of 49 (49%) infants who had abnormalities at birth went on to have normal test results in the second or third year of life. By contrast, 17 of 68 infants (25%) who had normal assessments at birth had below-average developmental testing or had abnormalities in hearing or vision by age 32 months.

“This work follows babies who were born in 2015 and 2016. It’s heartening that some babies born with abnormalities tested in the normal range later in life, though it’s unclear whether any specific interventions help to deliver these positive findings,” says Dr. Mulkey, a fetalneonatal neurologist in the Division of Fetal and Transitional Medicine at Children’s National in Washington, D.C. “And it’s quite sobering that babies who appeared normal at birth went on to develop abnormalities due to that early Zika exposure.”

It’s unclear how closely the findings apply to the vast majority of U.S. women whose Zika infections were asymptomatic.

“This study adds to the growing body of research that argues in favor of ongoing follow-up for Zika-exposed children, even if their neurologic exams were reassuring at birth,” Dr. Mulkey adds. “As Zika-exposed children approach school age, it’s critical to better characterize the potential implications for the education system and public health.”

In addition to Dr. Mulkey, the perspective’s senior author, William J. Muller, Northwestern University, was the commentary’s lead author.

zika virus

Neuroimaging essential for Zika cases

zika virus

About three years ago, Zika virus emerged as a newly recognized congenital infection, and a growing body of research indicates the damage it causes differs from other infections that occur in utero.

Seventy-one of 110 Brazilian infants at the highest risk for experiencing problems due to exposure to the Zika virus in the womb experienced a wide spectrum of brain abnormalities, including calcifications and malformations in cortical development, according to a study published July 31, 2019 in JAMA Network Open.

The infants were born at the height of Brazil’s Zika epidemic, a few months after the nation declared a national public health emergency. Already, many of the infants had been classified as having the severe form of congenital Zika syndrome, and many had microcephaly, fetal brain disruption sequence, arthrogryposis and abnormal neurologic exams at birth.

These 110 infants “represented a group of ZIKV-exposed infants who would be expected to have a high burden of neuroimaging abnormalities, which is a difference from other reported cohorts,” Sarah B. Mulkey, M.D., Ph.D., writes in an invited commentary published in JAMA Network Open that accompanies the Rio de Janeiro study. “Fortunately, many ZIKV-exposed infants do not have abnormal brain findings or a clinical phenotype associated with congenital Zika syndrome,” adds Dr. Mulkey, a fetalneonatal neurologist in the Division of Fetal and Transitional Medicine at Children’s National in Washington, D.C.

Indeed, a retrospective cohort of 82 women exposed to Zika during their pregnancies led by a research team at Children’s National found only three pregnancies were complicated by severe fetal brain abnormalities. Compared with the 65% abnormal computed tomography (CT) or magnetic resonance imaging (MRI) findings in the new Brazilian study, about 1 in 10 (10%) of babies born to women living in the continental U.S. with confirmed Zika infections during pregnancy had Zika-associated birth defects, according to the Centers for Disease Control and Prevention.

“There appears to be a spectrum of brain imaging abnormalities in ZIKV-exposed infants, including mild, nonspecific changes seen at cranial US [ultrasound], such as lenticulostriate vasculopathy and germinolytic cysts, to more significant brain abnormalities, such as subcortical calcifications, ventriculomegaly and, in its most severe form, thin cortical mantle and fetal brain disruption sequence,” Dr. Mulkey writes.

About three years ago, Zika virus emerged as a newly recognized congenital infection, and a growing body of research indicates the damage it causes differs from other infections that occur in utero. Unlike congenital cytomegalovirus infection, cerebral calcifications associated with Zika are typically subcortical, Dr. Mulkey indicates. What’s more, fetal brain disruption sequence seen in Zika-exposed infants is unusual for other infections that can cause microcephaly.

“Centered on the findings of Pool, et al, and others, early neuroimaging remains one of the most valuable investigations of the Zika-exposed infant,” Dr. Mulkey writes, including infants who are not diagnosed with congenital Zika syndrome.  She recommends:

  • Cranial ultrasound as the first-line imaging option for infants, if available, combined with neurologic and ophthalmologic exams, and brainstem auditory evoked potentials
  • Zika-exposed infants with normal cranial ultrasounds do not need additional imaging unless they experience a developmental disturbance
  • Zika-exposed infants with abnormal cranial ultrasounds should undergo further neuroimaging with low-dose cranial CT or brain MRI.

Autonomic nervous system appears to function well regardless of mode of childbirth

Late in pregnancy, the human body carefully prepares fetuses for the rigors of life outside the protection of the womb. Levels of cortisol, a stress hormone, ramp up and spike during labor. Catecholamines, another stress hormone, also rise at birth, helping to kick start the necessary functions that the baby will need to regulate breathing, heartbeat, blood pressure and energy metabolism levels at delivery. Oxytocin surges, promoting contractions for the mother during labor and stimulating milk production after the infant is born.

These processes also can play a role in preparing the fetal brain during the transition to life outside the womb by readying the autonomic nervous system and adapting its cerebral connections. The autonomic nervous system acts like the body’s autopilot, taking in information it needs to ensure that internal organs run steadily without willful action, such as ensuring the heart beats and eyelids blink at steady intervals. Its yin, the sympathetic division, stimulates body processes while its yang, the parasympathetic division, inhibits them.

Infants born preterm have reduced autonomic function compared with their full-term peers and also face possible serious neurodevelopmental impairment later in life. But is there a difference in autonomic nervous system function for full-term babies after undergoing labor compared with infants delivered via cesarean section (C-section)?

A team from the Children’s National Inova Collaborative Research Program (CNICA) – a research collaboration between Children’s National in Washington, D.C., and Inova Women’s and Children’s Hospital in Virginia – set out to answer that question in a paper published online July 30, 2019, in Scientific Reports.

They enrolled newborns who had experienced normal, full-term pregnancies and recorded their brain function and heart performance when they were about 2 days old. Infants whose conditions were fragile enough to require observation in the neonatal intensive care unit were excluded from the study. Of 167 infants recruited for the prospective cohort study, 118 newborns had sufficiently robust data to include them in the research.  Of these newborns:

  • 62 (52.5%) were born by vaginal delivery
  • 22 (18.6%) started out with vaginal delivery but ultimately switched to C-section based on failure to progress, failed labor induction or fetal intolerance to labor
  • And 34 (28.8%) were born by elective C-section.

The CNICA research team swaddled infants for comfort and slipped electrode nets over their tiny heads to simultaneously measure heart rate variability and electrocortical function through non-invasive techniques. The team hypothesized that infants who had been exposed to labor would have enhanced autonomic tone and higher cortical electroencephalogram (EEG) power than babies born via C-section.

“In a low-risk group of babies born full-term, the autonomic nervous system and cortical systems appear to function well regardless of whether infants were exposed to labor prior to birth,” says Sarah B. Mulkey, M.D., Ph.D., a fetalneonatal neurologist in the Division of Fetal and Transitional Medicine at Children’s National and the study’s lead author.

However, infants born by C-section following a period of labor had significantly increased accelerations in their heart rates. And the infants born by C-section during labor had significantly lower relative gamma frequency EEG at 25.2 hours old compared with the other two groups studied.

“Together these findings point to a possible increased stress response and arousal difference in infants who started with vaginal delivery and finished delivery with C-section,” Dr. Mulkey says. “There is so little published research about the neurologic impacts of the mode of delivery, so our work helps to provide a normal reference point for future studies looking at high-risk infants, including babies born preterm.”

Because the research team saw little differences in autonomic tone or other EEG frequencies when the infants were 1 day old, future research will explore these measures at different points in the newborns’ early life as well as the role of the sleep-wake cycle on heart rate variability.

Focusing on the “little brain” to rescue cognition

illustration of brain showing cerebellum

Research faculty at Children’s National in Washington, D.C., with colleagues recently published a review article in Nature Reviews Neuroscience that covers the latest research about how abnormal development of the cerebellum leads to a variety of neurodevelopmental disorders.

Cerebellum translates as “little brain” in Latin. This piece of anatomy – that appears almost separate from the rest of the brain, tucked under the two cerebral hemispheres – long has been known to play a pivotal role in voluntary motor functions, such as walking or reaching for objects, as well as involuntary ones, such as maintaining posture.

But more recently, says Aaron Sathyanesan, Ph.D., a postdoctoral research fellow at the Children’s Research Institute, the research arm of Children’s National  in Washington, D.C., researchers have discovered that the cerebellum is also critically important for a variety of non-motor functions, including cognition and emotion.

Sathyanesan, who studies this brain region in the laboratory of Vittorio Gallo, Ph.D., Chief Research Officer at Children’s National and scientific director of the Children’s Research Institute, recently published a review article with colleagues in Nature Reviews Neuroscience covering the latest research about how altered development of the cerebellum contributes to a variety of neurodevelopmental disorders.

These disorders, he explains, are marked by problems in the nervous system that arise while it’s maturing, leading to effects on emotion, learning ability, self-control, or memory, or any combination of these. They include diagnoses as diverse as intellectual disability, autism spectrum disorder (ASD), attention-deficit/hyperactivity disorder and Down syndrome.

“One reason why the cerebellum might be critically involved in each of these disorders,” Sathyanesan says, “is because its developmental trajectory takes so long.”

Unlike other brain structures, which have relatively short windows of development spanning weeks or months, the principal cells of the cerebellum – known as Purkinje cells – start to differentiate from stem cell precursors at the beginning of the seventh gestational week, with new cells continuing to appear until babies are nearly one year old.  In contrast, cells in the neocortex, a part of the brain involved in higher-order brain functions such as cognition, sensory perception and language is mostly finished forming while fetuses are still gestating in the womb.

This long window for maturation allows the cerebellum to make connections with other regions throughout the brain, such as extensive connections with the cerebral cortex, the outer layer of the cerebrum that plays a key role in perception, attention, awareness, thought, memory, language and consciousness. It also allows ample time for things to go wrong.

“Together,” Sathyanesan says, “these two characteristics are at the root of the cerebellum’s involvement in a host of neurodevelopmental disorders.”

For example, the review article notes, researchers have discovered both structural and functional abnormalities in the cerebellums of patients with ASD. Functional magnetic resonance imaging (MRI), an imaging technique that measures activity in different parts of the brain, suggests that significant differences exist between connectivity between the cerebellum and cortex in people with ASD compared with neurotypical individuals. Differences in cerebellar connectivity are also evident in resting-state functional connectivity MRI, an imaging technique that measures brain activity in subjects when they are not performing a specific task. Some of these differences appear to involve patterns of overconnectivity to different brain regions, explains Sathyanesan; other differences suggest that the cerebellums of patients with ASD don’t have enough connections to other brain regions.

These findings could clarify research from Children’s National and elsewhere that has shown that babies born prematurely often sustain cerebellar injuries due to multiple hits, including a lack of oxygen supplied by infants’ immature lungs, he adds. Besides having a sibling with ASD, premature birth is the most prevalent risk factor for an ASD diagnosis.

The review also notes that researchers have discovered structural changes in the cerebellums of patients with Down syndrome, who tend to have smaller cerebellar volumes than neurotypical individuals. Experimental models of this trisomy recapitulate this difference, along with abnormal connectivity to the cerebral cortex and other brain regions.

Although the cerebellum is a pivotal contributor toward these conditions, Sathyanesan says, learning more about this brain region helps make it an important target for treating these neurodevelopmental disorders. For example, he says, researchers are investigating whether problems with the cerebellum and abnormal connectivity could be lessened through a non-invasive form of brain stimulation called transcranial direct current stimulation or an invasive one known as deep brain stimulation. Similarly, a variety of existing pharmaceuticals or new ones in development could modify the cerebellum’s biochemistry and, consequently, its function.

“If we can rescue the cerebellum’s normal activity in these disorders, we may be able to alleviate the problems with cognition that pervade them all,” he says.

In addition to Sathyanesan and Senior Author Gallo, Children’s National study co-authors include Joseph Scafidi, D.O., neonatal neurologist; Joy Zhou and Roy V. Sillitoe, Baylor College of Medicine; and Detlef H. Heck, of University of Tennessee Health Science Center.

Children’s National ranked No. 6 overall and No. 1 for newborn care by U.S. News

Children’s National in Washington, D.C., is the nation’s No. 6 children’s hospital and, for the third year in a row, its neonatology program is No.1 among all children’s hospitals providing newborn intensive care, according to the U.S. News Best Children’s Hospitals annual rankings for 2019-20.

This is also the third year in a row that Children’s National has been in the top 10 of these national rankings. It is the ninth straight year it has ranked in all 10 specialty services, with five specialty service areas ranked among the top 10.

“I’m proud that our rankings continue to cement our standing as among the best children’s hospitals in the nation,” says Kurt Newman, M.D., President and CEO for Children’s National. “In addition to these service lines, today’s recognition honors countless specialists and support staff who provide unparalleled, multidisciplinary patient care. Quality care is a function of every team member performing their role well, so I credit every member of the Children’s National team for this continued high performance.”

The annual rankings recognize the nation’s top 50 pediatric facilities based on a scoring system developed by U.S. News. The top 10 scorers are awarded a distinction called the Honor Roll.

“The top 10 pediatric centers on this year’s Best Children’s Hospitals Honor Roll deliver outstanding care across a range of specialties and deserve to be nationally recognized,” says Ben Harder, chief of health analysis at U.S. News. “According to our analysis, these Honor Roll hospitals provide state-of-the-art medical expertise to children with rare or complex conditions. Their rankings reflect U.S. News’ assessment of their commitment to providing high-quality, compassionate care to young patients and their families day in and day out.”

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

Below are links to the five specialty services that U.S. News ranked in the top 10 nationally:

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

Vittorio Gallo Alpha Omega Alpha Award

Vittorio Gallo, Ph.D., Chief Research Officer at Children’s National, was inducted into Alpha Omega Alpha (AΩA), a national medical honor society that since 1902 has recognized excellence, leadership and research in the medical profession.

“I think it’s great to receive this recognition. I was very excited and surprised,” Gallo says of being nominated to join the honor society.

“Traditionally AΩA membership is based on professionalism, academic and clinical excellence, research, and community service – all in the name of ‘being worthy to serve the suffering,’ which is what the Greek letters AΩA stand for,” says Panagiotis Kratimenos, M.D., Ph.D., an ΑΩΑ member and attending neonatologist at Children’s National who conducts neuroscience research under Gallo’s mentorship. Dr. Kratimenos nominated his mentor for induction.

“Being his mentee, I thought Gallo was an excellent choice for AΩΑ faculty member,” Dr. Kratimenos says. “He is an outstanding scientist, an excellent mentor and his research is focused on improving the quality of life of children with brain injury and developmental disabilities – so he serves the suffering. He also has mentored numerous physicians over the course of his career.”

Gallo’s formal induction occurred in late May 2019, just prior to the medical school graduation at the George Washington University School of Medicine & Health Sciences (GWSMHS) and was strongly supported by Jeffrey S. Akman, Vice President for Health Affairs and Dean of the university’s medical school.

“I’ve been part of Children’s National and in the medical field for almost 18 years. That’s what I’m passionate about: being able to enhance translational research in a clinical environment,” Gallo says. “In a way, this recognition from the medical field is a perfect match for what I do. As Chief Research Officer at Children’s National, I am charged with continuing to expand our research program in one of the top U.S. children’s hospitals. And, as Associate Dean for Child Health Research at GWSMHS, I enhance research collaboration between the two institutions.”

Prenatal screening: the story of two siblings

Alex and Stephen Monaco

Stephen Monaco with his brother before a life-changing incident in 2001.

Jana and Tom Monaco have four children and two, Stephen and Caroline, were born with isovaleric acidemia (IVA) and secondary carnitine deficiency, a rare metabolic disorder. This genetic condition prevents the body from producing enzymes to break down the amino acid leucine, found in many proteins – from nuts and beans to chicken and fish. If undetected, the condition, which affects about one in 250,000 children, can be fatal. IVA can also lead to autism or severe brain damage. Fortunately, newborn screenings in every state now detect most IVA cases.

Eighteen years ago, a series of events happened with Stephen, age 3.5 at the time, which led to his diagnosis of having IVA and secondary carnitine deficiency. He celebrated his grandmother’s birthday with a family dinner on Memorial Day. The next day he woke up with symptoms of a stomach virus, which the family treated as such. The following morning he didn’t wake up at all. Jana went to his room to check on him and realized something was wrong. She called an ambulance and within 24 hours Stephen fell into a coma in her arms. He was immediately put on life support at a Virginia hospital.

Amy Lewanda, M.D., a geneticist, and Craig Futterman, M.D., an intensivist, both of whom now work at Children’s National Health System, delivered news about the condition: IVA is an inability for the IVD gene to create enzymes to break down protein. Within a 24- to 48-hour period, Stephen’s body flooded with isovaleric acid it couldn’t break down. Once the acid reached his brain he was paralyzed. Jana mentions you could find him in the emergency department of the hospital by following the odor: He reeked of ketones and isovaleric acid, which accumulated in his blood and body tissue. His blood glucose level was so low that he was practically in a diabetic coma.

If the Monaco family was able to get his blood checked locally at the hospital – which the clinicians did not yet have the ability to do because this condition is so rare – they may have been able to receive an early diagnosis, enabling them to intervene in infancy, as they did with their youngest daughter, Caroline.

After the diagnosis, in hindsight, Jana and Tom recognized Stephen’s symptoms as a toddler: picky eating, anemia, rejection of protein-rich foods, such as favoring jelly over peanut butter on a PB&J sandwich, opting for easy carbs, since they are easier for those with IVA to process, and breastfeeding longer, since breast milk is lower in protein. He had a peculiar odor trailing from his diaper, a common symptom of this condition. They also remembered he had a harder time recovering from a stomach virus, which left him weak and floppy, compared to one of his brothers, who had the same flu but bounced back faster. As parents, they did everything they could to promote healthy growth and development for their children – from properly installing  car seats to staying up-to-date on vaccines and enrolling everyone in activities, like Little League. They only wished they could have detected this condition earlier.

A second chance arrived six months after Stephen was diagnosed with IVA: Jana and Tom learned they were pregnant with Caroline. From studying Stephen’s condition, they knew Caroline had a 25 percent chance of having IVA and secondary carnitine deficiency. (Jana and Tom are recessive carriers for a mutated IVD gene, but remain asymptomatic.) They scheduled an amniocentesis, a prenatal test that provides information about a baby’s health from sample amniotic fluid, which can diagnose genetic defects and fetal infections. Caroline was just 16 weeks in utero, but abnormal metabolites from the amniotic fluid sample confirmed she had IVA and secondary carnitine deficiency.

Caroline Monaco

Caroline, a healthy teenager with IVA, is an example of the benefits of newborn screenings and early-life medical interventions.

Having advance knowledge about the condition enabled doctors and geneticists to create a plan for her delivery, which made a difference between her long-term prognosis and Stephen’s. After birth, she was transferred to the neonatal intensive care unit at Children’s National. She was fed a formula that prevented excess isovaleric acid build-up, part of an hour-by-hour protocol to ensure she stayed healthy. Caroline is now 16. She plays the viola in her school orchestra, rides horses and excels in school.

When Stephen was born, the state of Virginia, where the Monaco family lives, screened for eight prenatal conditions, such as PKU, a rare but more common condition. The state now screens for 31 conditions, thanks in part to Jana, Stephen and Caroline. The list grows as research evolves. Jana started advocating for these efforts in Richmond and on Capitol Hill when Caroline was 2. Her approach: Take Stephen and Caroline to her state capitol and to the U.S. Capitol to push for statewide newborn screenings – visually showing the same condition, but with two very different outcomes. How could anyone say no?

She worked with the Virginia Genetics Advisory Council and with the Health and Human Services Secretary Advisory Committee to pass the legislation, which helped detect other organic acidemias – inherited conditions that prevent babies from breaking down amino acids found in protein, creating potentially toxic situations, similar to Stephen’s. They advocated for adding other conditions to the panel, like severe combined immunodeficiency, commonly referred to as “bubble boy” syndrome. Stephan was the only newborn screening advocate in attendance with a disability. Now all 50 states have implemented these screenings.

Attendees of the charity golf event

The Monaco family raised $100,000 for the genetics division and ongoing IVA research at Children’s National Health System.

The family isn’t done yet. On Oct. 26, Stephen will celebrate his 22nd birthday and a fifth-annual golf tournament, created in his honor, to raise awareness about and support for IVA and similar conditions. The Monaco family started this tradition in 2015 on Stephen’s 18th birthday and have raised $100,000 for the genetics division at Children’s National. They hope Stephen’s legacy will leave others with a message they keep framed in their Virginia home: Learn from yesterday, live for today and hope for tomorrow.

They educate Caroline along the way, noting the annual golf tournament and their advocacy supports ongoing IVA research and care – ensuring that she and others with these rare metabolic conditions continue to live a long, healthy life, echoing their longstanding partnership with Children’s National to help children grow up stronger.
