A rare prescription: Providing children with palliative care

Telemedicine

A pilot program at Children’s National enabled parents of children with extremely rare diseases to receive in-person or virtual health consultations with a trained provider.

Pediatric advance care planning (pACP) and making complex  medical decisions is especially difficult for parents of children with extremely rare diseases. Imagine if your child is the only person in the world with a rare disease that may limit basic functions: eating, breathing, walking and talking. Now, imagine you are presented with two scenarios: Experiment with a new drug to see if it improves your child’s conditions or plan for near-future, end-of-life care.

While these types of difficult decisions for parents of children with rare diseases are common, a new counseling model, based on a four-session pilot program conducted at Children’s National, aims to ease this process by providing parents with a comprehensive support plan.

On Oct. 15 and 16, Maureen Lyon, Ph.D., a clinical psychologist at Children’s National and a professor of pediatrics at the George Washington University School of Medicine and Health Sciences, will present “Living on the Precipice: The Journey of Children with Rare Diseases and Their Families” at a poster session at the National Organization for Rare Disorders’ Rare Disease and Orphan Products Breakthrough Summit at the Marriott Wardman Park in Washington.

Dr. Lyon will highlight key take-home points she observed during the pilot program:

  • Background: Eight families were recruited for the pilot program and seven enrolled. Six completed the four-session program, which was spread out over two months.
    • All parents were mothers, but two fathers joined for the goal-planning care conversation sessions. Some families brought their children to visits.
    • Five parents were married and two were single.
    • Four families identified as Caucasian, three families identified as African American, and one family identified as American Indian or Alaska Native.
  • Visits: About half of the families – three – attended the sessions at Children’s National. Four used the telemedicine option. A research nurse, clinical psychologist and advanced practice nurse participated in the 60- to 90-minute sessions.
  • Plans: The families discussed basic palliative care needs, such as comprehensive care coordination, which is highly individualized, before discussing their goals of care. After their needs and goals were discussed, the families created advance care plans to guide them during a medical crisis.
  • Results: Out of the six parents who completed the study, the mean positive caregiver appraisal score increased from 4.5. To 4.7, mean family well-being increased from 3.9 to 4.1, and the mean score for meaning and peace increased from 21.4 to 23.3. The scores were calculated by using the Carer Support Needs Assessment Tool (CSNAT) during the assessment and with modified protocols to assess quality of life and caregiver appraisal after the intervention.

“The goal of palliative care is to optimize quality of life for children with life-threatening illnesses and their families by anticipating, preventing and treating suffering in all its forms,” explains Maureen Lyon, Ph.D. “This is delivered throughout illness and addresses physical, intellectual, emotional, social and spiritual needs.”

“These sessions increased a family’s sense of overall well-being,” says Jessica Thompkins, B.S.N., R.N., C.P.N., a research nurse coordinator with the FAmily CEntered Advanced Care Planning Team (FACE) and a co-author of the poster. “The families felt better just by knowing that they had time scheduled each week to connect with a trained medical provider to discuss a range for options they need as a caregiver, from everyday care at home to long-term health care planning at the hospital.”

The top-rated support need identified by all parents, according to the survey: “Knowing what to expect in the future when caring for their children.”

“The goal of palliative care is to optimize quality of life for children with life-threatening illnesses and their families by anticipating, preventing and treating suffering in all its forms,” says Dr. Lyon. “This is delivered throughout illness and addresses physical, intellectual, emotional, social and spiritual needs.”

The researchers would like to use this pilot to partner with other medical centers to create an evidence-based template to support the palliative care needs of family caregivers who have children with life-limiting rare diseases. Their goal is to improve a family caregiver’s quality of life, over time, and increase the completion and documentation of advance care plans for children of all ethnic and racial groups.

Rare diseases are defined as a disease that affects fewer than 200,000 people in the U.S. Extremely rare diseases, including those observed in this pilot, may affect just one or a few people in the world.

The rare disease pilot program is based on previous pACP models with adolescent HIV and pediatric cancer populations.

Connecting allied health professionals in pediatric nephrology

With the meeting in Washington this year, Children’s National Health System will be the local host, a distinct honor for an academic medical center that treats hundreds of nephrology patients each year, says pediatric Nephrologist Asha Moudgil, M.D., who directs Children’s kidney transplant service.

Pediatric nephrology is a relatively small specialty worldwide, encompassing just a few hundred doctors in the U.S. For each allied health field that provides collaborative care with these physicians – including nutrition, child-life, psychology and social work – the numbers of providers are even smaller. There are no national meetings for these individual subspecialty fields and no venues to meet new like-minded colleagues or learn about new research or protocols.

Six years ago, the American Society of Pediatric Nephrology (ASPN) aimed to help resolve this dilemma by launching a new multidisciplinary symposium that brings together allied health professionals of all kinds within pediatric nephrology.

Each year, the “ASPN Multidisciplinary Symposium” changes locations, allowing the meeting to target different regional groups of allied health professionals based on geography. With the meeting in Washington this year, Children’s National Health System will be the local host, a distinct honor for an academic medical center that treats hundreds of nephrology patients each year, says pediatric Nephrologist Asha Moudgil, M.D., who directs Children’s kidney transplant service.

There are multiple advantages to having the symposium in Washington, Dr. Moudgil explains. One is access to Children’s experts in this field, who have a wealth of experience in managing issues that affect patients who live in the greater Washington area. For example, the keynote address scheduled for the meeting’s opening night will be delivered by Jennifer Verbesey, M.D., Children’s surgical director of pediatric kidney transplantation, focusing on living donation in minority populations. Living kidney donors and recipients who are minorities have unique issues that can affect organ longevity, explains Dr. Moudgil, which may not be well known by all clinicians.

Children’s speakers also focus prominently in the main session on the second day, including:

  • Angela Boadu, RD, LDN/LD, a registered dietitian, and Kaushalendra Amatya, Ph.D., a psychologist, are giving a talk about nutrition and the psychosocial aspects of obesity
  • Surgeon Evan Nadler, M.D., director of Children’s Bariatric Surgery Program, is speaking about bariatric surgery before and after transplantation
  • Nurse Practitioner Christy Petyak, CPNP-PC, and Social Worker Heidi Colbert, LICSW, CCTSW, NSW-C, are leading breakout sessions about the practical aspects of immunosuppressive therapy and resources for uninsured patients
  • Amatya, the Children’s psychologist, also is leading a breakout session on internalizing psychological disorders in pediatric renal patients and
  • Registered Dietitian Kristen Sgambat, Ph.D., RD, and Dr. Moudgil are co-leading a breakout session on nutritional challenges and enteral supplementation in chronic kidney disease.

Another advantage to holding the meeting in the nation’s capital is its close proximity to government research and federal regulatory agencies, such as the Food and Drug Administration (FDA) and the National Institutes of Health (NIH). Speakers from both agencies will be present, talking about how the FDA approves medicines for pediatric patients and offering details about the NIH’s rare disease program.

Besides the abundance of more formal knowledge-sharing, Dr. Moudgil adds, there will be plenty of opportunities for attendees to network, making connections within and outside their own respective fields.

“This is a platform for making long-term professional relationships,” Dr. Moudgil says. “Even if you’re the sole clinician representing your specialty at your own institution, you’ll be able to connect with other specialists at institutions across the country. You’re not only acquiring new information, you’re acquiring a group of colleagues you can connect with this year and those professional relationships can extend far into the future.”

Predicting kids’ outcomes after concussion

A concussion symptom measurement tool, developed by investigators at Children’s National Health System, allows other researchers to collect valuable evidence about the natural progression of symptoms and recovery for children. The tool, Post-Concussion Symptom Inventory (PCSI), was a key tool in the recent large-scale multi-center prospective study of recovery trajectory for children, which was published online in JAMA Pediatrics Sept. 4, 2018.

That study included 2,716 children between the ages of 5 and 17, and identified major trends in symptom improvement post concussion, such as:

  • Children younger than 12 experience primary symptom improvement in the first two weeks
  • Pre-adolescents, male adolescents and teens experience primary symptom improvement in the first four weeks and
  • Female adolescents take longer to perceive primary symptom improvements than children, pre-adolescents and male counterparts.

“We’ve known for many years that different people experience concussion recovery very differently. This study is the first to provide significant evidence of what we should expect to see in terms of symptom improvement for children and teens,” says Gerard Gioia, Ph.D., chief of the Division of Neuropsychology at Children’s National and director of its Safe Concussion Outcome Recovery and Education Program, who co-authored the study and whose team developed the PCSI measurement tool. “Ultimately, these findings are an important step in predicting outcomes after a concussion and developing treatment plans that get kids back to school and sports safely, when they are ready.”

Dr. Gioia and his team also recently received a Centers for Disease Control and Prevention (CDC) grant to develop a new smartphone application, Online Treatment Recovery Assistant for Concussion in Kids (OnTRACK), that applies several concussion tools developed at Children’s National, including the same one applied in the JAMA Pediatrics study, to track individual symptoms over time.

The OnTRACK app will report concussion symptoms on a regular basis (daily or weekly) and map their trajectory, so doctors can see when recovery is proceeding along the expected pathway. Alternatively, clinicians will receive an alert when a child’s recovery misses targets and warrants further investigation and possible referral to a specialist.

Neuro- and gender-diverse teens find their voices

John Strang

“These autistic young people spoke a lot about their gender and gender needs and their descriptions of gender dysphoria were deeply emotional. One of the common characteristics of autism is reduced communication of feelings, yet many of these young people were very clear about the anguish that gender dysphoria caused for them and also their need for gender-related interventions,” says John Strang, Psy.D., director of the Gender and Autism Program at Children’s National Health System and study lead.

“They Thought It Was An Obsession” is the title of a qualitative study from the Journal of Autism and Developmental Disorders, that provides an unprecedented glimpse into the development, thoughts, perceptions, feelings and needs of this poorly understood but significant subgroup of transgender and gender minority teens.

The title is an accurate reflection of the study’s analysis, which finds that the accounts of gender dysphoria in autistic transgender youth parallel those of transgender young people without autism. These findings stand in contrast to previous studies asserting the idea that gender dysphoria in autistic youth is driven primarily by superficial autism-related interests.

“These autistic young people spoke a lot about their gender and gender needs and their descriptions of gender dysphoria were deeply emotional. One of the common characteristics of autism is reduced communication of feelings, yet many of these young people were very clear about the anguish that gender dysphoria caused for them and also their need for gender-related interventions,” says John Strang, Psy.D., director of the Gender and Autism Program at Children’s National Health System and study lead.

Additionally, the autistic characteristics of these young people – which may reduce their concern for social conventions – often lead them to express their gender in individual and sometimes surprising ways.

“A transgender autistic young woman may wear a full beard and understand her gender identity as something completely separate from her appearance,” says Dr. Strang. “The cooccurrence of gender identity-diversity and autism may reveal something of the deeper nature of gender when the overlay of social gender expectations is reduced.”

The study followed 22 autistic transgender teens over nearly two years. It is the first study of its kind to track and follow up with this many youth with the cooccurrence over a significant period of time. The authors believe the report can serve as a guide for how clinicians, peers and families can better support and understand teens who are both neurodiverse and gender diverse.

The study’s methodology is also novel, as it features the inclusion of a slate of autistic gender-diverse coanalysts and coauthors who partnered in the interpretation of the youth provided data.

The coauthor group also included a retransitioned (previously transgender) self-advocate coanalyst to help provide context regarding the experiences and trajectories of the few study participants who moved away from transgender identity during the study’s duration.

Reid Caplan of the Autistic Self-Advocacy Network, an autistic transgender self-advocate and one of the study’s coauthors noted, “Too often in medical literature, the overlap between autistic and transgender identities is described in a way that pathologizes both of these communities. As an autistic transgender young adult, I feel privileged to be a coauthor of research that puts the voices of autistic and gender-diverse youth at the forefront. By giving these youth control over their own narratives, this study exemplifies a key value of the self-advocate community: Nothing about us, without us!”

Perinatal hypoxia associated with long-term cerebellar learning deficits and Purkinje cell misfiring

The type of hypoxia that occurs with preterm birth is associated with locomotor miscoordination and long-term cerebellar learning deficits but can be partially alleviated with an off-the-shelf medicine, according to a study using a preclinical model.

Oxygen deprivation associated with preterm birth leaves telltale signs on the brains of newborns in the form of alterations to cerebellar white matter at the cellular and the physiological levels. Now, an experimental model of this chronic hypoxia reveals that those cellular alterations have behavioral consequences.

Chronic sublethal hypoxia is associated with locomotor miscoordination and long-term cerebellar learning deficits in a clinically relevant model of neonatal brain injury, according to a study led by Children’s National Health System researchers published online Aug. 13, 2018, by Nature Communications. Using high-tech optical and physiological methods that allow researchers to turn neurons on and off and an advanced behavioral tool, the research team finds that Purkinje cells fire significantly less often after injury due to perinatal hypoxia. However, an off-the-shelf medicine now used to treat epilepsy enables those specialized brain cells to regain their ability to fire, improving locomotor performance.

Step out of the car onto the pavement, hop up to the level of the curb, stride to the entrance, and climb a flight of stairs. Or, play a round of tennis. The cerebellum coordinates such locomotor performance and muscle memory, guiding people of all ages as they adapt to a changing environment.

“Most of us successfully coordinate our movements to navigate the three-dimensional spaces we encounter daily,” says Vittorio Gallo, Ph.D., Children’s Chief Research Officer and the study’s senior author. “After children start walking, they also have to learn how to navigate the environment and the spaces around them.”

These essential tasks, Gallo says, are coordinated by Purkinje cells, 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. The rate of development of the fetal cerebellum dramatically increases at a time during pregnancy that often coincides with preterm birth, which can delay or disrupt normal brain development.

“It’s almost like a short circuit. Purkinje cells play a very crucial role, and when the frequency of their firing is diminished by injury the whole output of this brain region is impaired,” Gallo says. “For a family of a child who has this type of impaired neural development, if we understand the nature of this disrupted circuitry and can better quantify it, in terms of locomotor performance, then we can develop new therapeutic approaches.”

Study authors Aaron Sathyanesan, Ph.D., Joseph Abbah, B.Pharm., Ph.D., Srikanya Kundu, Ph.D. and Vittorio Gallo, Ph.D.

The research team leveraged a fully automated, computerized apparatus that looks like a ladder placed on a flat surface, encased in glass, with a darkened box at either end. Both the hypoxic and control groups had training sessions during which they learned how to traverse the horizontal ladder, coaxed out of the darkened room by a gentle puff of air and a light cue. Challenge sessions tested their adaptive cerebellar locomotor learning skills. The pads they strode across were pressure-sensitive and analyzed individual stepping patterns to predict how long it should take each to complete the course.

During challenge sessions, obstacles were presented in the course, announced by an audible tone. If learning was normal, then the response to the tone paired with the obstacle would be a quick adjustment of movement, without breaking stride, says Aaron Sathyanesan, Ph.D., co-lead author. Experimental models exposed to perinatal hypoxia showed significant deficits in associating that tone with the obstacle.

“With the control group, we saw fewer missteps during any given trial,” Sathyanesan says. “And, when they got really comfortable, they took longer steps. With the hypoxic group, it took them longer to learn the course. They made a significantly higher number of missteps from day one. By the end of the training period, they could walk along all of the default rungs, but it took them longer to learn how to do so.”

Purkinje cells fire two different kinds of spikes. Simple spikes are a form of constant activity as rhythmic and automatic as a heartbeat. Complex spikes, by contrast, occur less frequently. Sathyanesan and co-authors say that some of the deficits that they observed were due to a reduction in the frequency of simple spiking.

Two weeks after experiencing hypoxia, the hypoxic group’s locomotor performance remained significantly worse than the control group, and delays in learning could still be seen five weeks after hypoxia.

Gamma-aminobutyric acid (GABA), a neurotransmitter, excites immature neurons before and shortly after birth but soon afterward switches to having an inhibitory effect within in the cerebellum, Sathyanesan says. The research team hypothesizes that reduced levels of excitatory GABA during early development leads to long-term motor problems. Using an off-the-shelf drug to increase GABA levels immediately after hypoxia dramatically improved locomotor performance.

“Treating experimental models with tiagabine after hypoxic injury elevates GABA levels, partially restoring Purkinje cells’ ability to fire,” Gallo says. “We now know that restoring GABA levels during this specific window of time has a beneficial effect. However, our approach was not specifically targeted to Purkinje cells. We elevated GABA everywhere in the brain. With more targeted and selective administration to Purkinje cells, we want to gauge whether tiagabine has a more powerful effect on normalizing firing frequency.”

In addition to Gallo and Sathyanesan, Children’s co-authors include Co-Lead Author, Srikanya Kundu, Ph.D., and Joseph Abbah, B.Pharm., Ph.D., both of Children’s Center for Neuroscience Research.

Effectively expressing empathy to improve ICU care

Tessie October

“Families who feel we’re really listening and care about what they have to say are more likely to feel comfortable as they put their child’s life in our hands a second, third or fourth time,” says Tessie W. October, M.D., M.P.H.

In nearly every intensive care unit (ICU) at every pediatric hospital across the country, physicians hold numerous care conferences with patients’ family members daily. Due to the challenging nature of many these conversations – covering anything from unexpected changes to care plans for critically ill children to whether it’s time to consider withdrawing life support – these talks tend to be highly emotional.

That’s why physician empathy is especially important, says Tessie W. October, M.D., M.P.H., critical care specialist at Children’s National Health System.

Several studies have shown that when families believe that physicians hear, understand or share patients’ or their family’s emotions, patients can achieve better outcomes, Dr. October explains. When families feel like their physicians are truly empathetic, she adds, they’re more likely to share information that’s crucial to providing the best care.

“For the most part, our families do not make one-time visits. They return multiple times because their children are chronically ill,” Dr. October says. “Families who feel we’re really listening and care about what they have to say are more likely to feel comfortable as they put their child’s life in our hands a second, third or fourth time. They’re also less likely to regret decisions made in the hospital, which makes them less likely to experience long-term psychosocial outcomes like depression and anxiety.”

What’s the best way for physicians to show empathy? Dr. October and a multi-institutional research team set out to answer this question in a study published online in JAMA Network Open on July 6, 2018.

With families’ consent, the researchers recorded 68 care conferences that took place at Children’s pediatric ICU (PICU) between Jan. 3, 2013, to Jan. 5, 2017. These conversations were led by 30 physicians specializing in critical care, hematology/oncology and other areas and included 179 family members, including parents.

During these conferences, the most common decision discussed was tracheostomy placement – a surgical procedure that makes an opening in the neck to support breathing – followed by the family’s goals, other surgical procedures or medical treatment. Twenty-two percent of patients whose care was discussed during these conferences died during their hospitalization, highlighting the gravity of many of these talks.

Dr. October and colleagues analyzed each conversation, counting how often the physicians noticed opportunities for empathy and how they made empathetic statements. The researchers were particularly interested in whether empathetic statements were “buried,” which means they were:

  • Followed immediately by medical jargon
  • Followed by a statement beginning with the word “but” that included more factual information or
  • Followed by a second physician interrupting with more medical data.

That compares with “unburied” empathy, which was followed only by a pause that provided the family an opportunity to respond. The research team examined what happened after each type of empathetic comment.

The researchers found that physicians recognized families’ emotional cues 74 percent of the time and made 364 empathetic statements. About 39 percent of these statements were buried. In most of these instances, says Dr. October, the study’s lead author, the buried empathy either stopped the conversation or led to family members responding with a lack of emotion themselves.

After the nearly 62 percent of empathetic statements that were unburied, families tended to answer in ways that revealed their hopes and dreams for the patient, expressed gratitude, agreed with care advice or expressed mourning—information that deepened the conversation and often offered critical information for making shared decisions about a patient’s care.

Physicians missed about 26 percent of opportunities for empathy. This and striving to make more unburied empathetic statements are areas ripe for improvement, Dr. October says.

That’s why she and colleagues are leading efforts to help physicians learn to communicate better at Children’s National. To express empathy more effectively, Dr. October recommends:

  • Slow down and be in the moment. Pay close attention to what patients are saying so you don’t miss their emotional cues and opportunities for empathy.
  • Remember the “NURSE” mnemonic. Empathetic statements should Name the emotion, show Understanding, show Respect, give Support or Explore emotions.
  • Avoid using the word “but” as a transition. When you follow an empathetic statement with “but,” Dr. October says, it cancels out what you said earlier.
  • Don’t be afraid to invite strong emotions. Although it seems counterintuitive, Dr. October says helping patients express strong feelings can help process emotions that are important for decision-making.

In addition to Dr. October, study co-authors include Zoelle B. Dizon, BA, Children’s National; Robert M. Arnold, M.D., University of Pittsburgh Medical Center; and Senior Author, Abby R. Rosenberg, M.D., MS, University of Washington School of Medicine.

Making weight: Ensuring that micro preemies gain pounds and inches

Tory Peitz and Victoria Catalano

Tory Peitz, R.N., (left) and Victoria Catalano, RDN, LD, CNSC, CLC, (right) Pediatric Dietitian Specialist in the Neonatal Intensive Care Unit at Children’s National Health System, measure the length of a micro preemie who weighed 1.5 pounds at birth.

A quality-improvement project to standardize feeding practices for micro preemies – preterm infants born months before their due date –  helped to boost their weight and nearly quadrupled the frequency of lactation consultations ordered in the neonatal intensive care unit (NICU), a multidisciplinary team from Children’s National Health System finds.

According to the Centers for Disease Control and Prevention, about 1 in 10 infants in 2016 was preterm, born prior to completing 37 gestational weeks of pregnancy. Micro preemies are the tiniest infants in that group, weighing less than 1,500 grams and born well before their brain, lungs and organs like the liver are fully developed.

As staff reviewed charts for very low birth weight preterm infants admitted to Children’s NICU, they found dramatic variation in nutritional practices among clinicians and a mean decline in delta weight Z-scores, a more sensitive way to monitor infants’ weight gain along growth percentiles for their gestational age. A multidisciplinary team that included dietitians, nurses, neonatologists, a lactation consultant and a quality-improvement leader evaluated nutrition practices and determined key drivers for improving nutrition status.

“We tested a variety of strategies, including standardizing feeding practices; maximizing intended delivery of feeds; tracking adequacy of calorie, protein and micronutrient intake; and maximizing use of the mother’s own breast milk,” says Michelande Ridoré, MS, a Children’s NICU quality-improvement lead who will present the group’s findings during the Virginia Neonatal Nutrition Association conference this fall. “We took nothing for granted: We reeducated everyone in the NICU about the importance of the standardized feeding protocol. We shared information about whether infants were attaining growth targets during daily rounds. And we used an infographic to help nursing moms increase the available supply of breastmilk,” Ridoré says.

On top of other challenges, very low birth weight preterm infants are born very lean, with minimal muscle. During the third trimester, pregnant women pass on a host of essential nutrients and proteins to help satisfy the needs of the fetus’ developing muscles, bones and brain. “Because preterm infants miss out on that period in utero, we add fortification to provide preemies with extra protein, phosphorus, calcium and zinc they otherwise would have received from mom in the womb,” says Victoria Catalano, RDN, LD, CNSC, CLC, a pediatric clinical dietitian in Children’s NICU and study co-author. Babies’ linear growth is closely related to neurocognitive development, Catalano says. A dedicated R.N.  is assigned to length boards for Children’s highest-risk newborns to ensure consistency in measurements.

Infants who were admitted within the first seven days of life and weighed less than 1,500 grams were included in the study. At the beginning of the quality-improvement project, the infants’ mean delta Z-score for weight was -1.8. By December 2018, that had improved to -1.3. And the number of lactation consultation ordered weekly increased from 1.1 to four.

“We saw marked improvement in micro preemies’ nutritional status as we reduced the degree of variation in nutrition practices,” says Mary Revenis, M.D., NICU medical lead on nutrition and senior author for the research. “Our goal was to increase mean delta Z-scores even more. To that end, we will continue to test other key drivers for improved weight gain, including zinc supplementation, updating infants’ growth trajectories in the electronic medical record and advocating for expanded use of birth mothers’ breast milk,” Dr. Revenis says.

In addition to Ridoré, Catalano and Dr. Revenis, study co-authors include Caitlin Forsythe MS, BSN, RNC-NIC, lead author; Rebecca Vander Veer RD, LD, CNSC, CLC, pediatric dietitian specialist; Erin Fauer RDN, LD, CNSC, CLC, pediatric dietitian specialist; Judith Campbell, RN, IBCLC, NICU lactation consultant; Eresha Bluth MHA; Anna Penn M.D., Ph.D., neonatalogist; and Lamia Soghier M.D., Med., NICU medical unit director.

Safeguarding fetal brain health in pregnancies complicated by CHD

Pregnant-Mom

During the last few weeks of pregnancy, certain regions of the fetal brain experience exponential growth but also are more vulnerable to injury during that high-growth period.

Yao Wu, Ph.D., a research postdoctoral fellow in the Developing Brain Research Laboratory at Children’s National Health System, has received a Thrasher Research Fund early career award to expand knowledge about regions of the fetal brain that are vulnerable to injury from congenital heart disease (CHD) during pregnancy.

CHD, the most common birth defect, can have lasting effects, including overall health issues; difficulty achieving milestones such as crawling, walking or running; and missed days at daycare or school, according to the Centers for Disease Control and Prevention. Brain injury is a major complication for infants born with CHD. Catherine Limperopoulos, Ph.D., director of Children’s brain imaging lab, was the first to provide in vivo evidence that fetal brain growth and metabolism in the third trimester of pregnancy is impaired within the womb.

“It remains unclear which specific regions of the fetal brain are more vulnerable to these insults in utero,” Limperopoulos says. “We first need to identify early brain abnormalities attributed to CHD and understand their impact on infants’ later behavioral and cognitive development in order to better counsel parents and effectively intervene during the prenatal period to safeguard brain health.”

During the last few weeks of pregnancy, certain regions of the fetal brain experience exponential growth but also are more vulnerable to injury during that high-growth period. The grant, $26,749 over two years, will underwrite “Brain Development in Fetuses With Congenital Heart Disease,” research that enables Wu to utilize quantitative, non-invasive magnetic resonance imaging (MRI) to compare fetal brain development in pregnancies complicated by CHD with brain development in healthy fetuses of the same gestational age.Wu will leverage quantitative, in vivo 3-D volumetric MRI to compare overall fetal and neonatal brain growth as well as growth in key regions including cortical grey matter, white matter, deep grey matter, lateral ventricles, external cerebrospinal fluid, cerebellum, brain stem, amygdala and the hippocampus.

The research is an offshoot of a prospective study funded by the National Institutes of Health that uses advanced imaging techniques to record brain growth in 50 fetuses in pregnancies complicated by CHD who need open heart surgery and 50 healthy fetuses. MRI studies are conducted during the second trimester (24 to 28 weeks gestational age), third trimester (33 to 37 weeks gestational age) and shortly after birth but before surgery. In addition, fetal and neonatal MRI measurements will be correlated with validated scales that measure infants’ and toddlers’ overall development, behavior and social/emotional maturity.

“I am humbled to be selected for this prestigious award,” Wu says. “The findings from our ongoing work could be instrumental in identifying strategies for clinicians and care teams managing high-risk pregnancies to optimize fetal brain development and infants’ overall quality of life.”

Screening for postpartum depression in the emergency department

Lenore Jarvis

“Some of these women had no idea how common postpartum depression was,” says Lenore Jarvis, M.D., M.Ed. “They thought they were crazy and felt alone and were bad moms.”

It’s a scenario that Children’s emergency medicine specialist Lenore Jarvis, M.D., M.Ed., has seen countless times: A mother brings her infant to the emergency department (ED) in the middle of the night with a chief complaint of the baby being fussy. Nothing she does can stop the incessant crying, she tells the triage nurse. When doctors examine the baby, they don’t see anything wrong. Often, this finding is reassuring. But, despite their best efforts to comfort her, the mother isn’t reassured and leaves the hospital feeling anxious and overwhelmed.

After these encounters, Dr. Jarvis wondered: Might the mother be the actual patient?

Postpartum depression (PPD) is the most common complication of childbirth, Dr. Jarvis explains, occurring in up to 20 percent of all mothers, and may be higher (up to 50 percent) in low-income and immigrant women. Far beyond simple “baby blues,” the mood disorder can have significant implications for the mother, her baby and the entire family. It can hinder mother-child bonding and lead to early discontinuation of breastfeeding, delayed immunizations, and child abuse and neglect. The associated effects on early brain development might cause cognitive and developmental delays for the infant and, later in life, can manifest as emotional and behavioral problems. PPD can disrupt relationships between parents. And suicide is the top cause of postpartum death.

Mothers are supposed to be screened routinely for PPD at postpartum visits with their maternal or pediatric health care providers. In addition, several medical professional societies – including the American Academy of Pediatrics and the American College of Obstetricians and Gynecologists – now recommend screening for PPD in the prenatal and postnatal periods and during routine well-child visits in the outpatient setting. But these screenings often don’t happen, Dr. Jarvis says, either because doctors aren’t following the recommendations or parents aren’t attending these visits due to barriers to health care access or other problems.

One way to sidestep these challenges, she says, is to provide PPD screening in the emergency setting.

“The ED becomes the safety net for people who are not routinely accessing regular checkups for themselves and their children,” Dr. Jarvis says. “If a mother is having an acute crisis in the middle of the night and feeling anxious and depressed, they often come to the emergency department for help.”

Dr. Jarvis and colleagues launched a pilot study in the Children’s ED to screen for PPD. For eight months beginning June 2015, the researchers invited English- and Spanish-speaking mothers who arrived at the ED with infants 6 months old or younger with complaints that didn’t necessitate immediate emergency care to take a short questionnaire on a computer tablet. This questionnaire included the Edinburgh Postnatal Depression Scale, a well-validated tool to screen for PPD, along with basic sociodemographic questions and queries about risk factors that other studies previously identified for PPD.

Just over half agreed to participate. When Dr. Jarvis and colleagues analyzed the results from these 209 mothers, they found that 27 percent scored positive for PPD, more than the average from previous estimates. Fourteen of those mothers reported having suicidal thoughts. Surprisingly, nearly half of participants reported that they’d never been screened previously for PPD, despite standing recommendations for routine screenings at mother and baby care visits, the research team writes in findings published online May 5, 2018, in Pediatric Emergency Care.

Based on the screening results, the researchers implemented a range of interventions. All mothers who participated in the study received an informational booklet from the March of Dimes on PPD. If mothers scored positive, they also received a local PPD resource handout and were offered a consultation with a social worker. Those with a strongly positive score were required to receive a social worker consultation and were given the option of “warm-line” support to PPD community partners, a facilitated connection to providers who offer individual or group therapy or home visits, or to a psychiatrist who might prescribe medication. Mothers with suicidal thoughts were assessed by a physician and assisted by crisis intervention services, if needed.

When the researchers followed up with mothers who screened positive one month later, an overwhelming majority said that screening in the ED was important and that the resources they were given had been key for finding help. Many commented that even the screening process seemed like a helpful intervention.

“Some of these women had no idea how common PPD was. They thought they were crazy and felt alone and were bad moms,” Dr. Jarvis says. “For someone to even ask about PPD made these women aware that this exists, and it’s something people care about.”

Many thanked her and colleagues for the follow-up call, she adds, saying that it felt good to be cared for and checked on weeks later. “It goes to show that putting support systems in place for these new mothers is very important,” she says.

Dr. Jarvis and ED colleagues are currently collaborating with social workers, neonatology and other Children’s National Health System care partners to start screening mothers in the neonatal intensive care unit (NICU) and ED for PPD. They plan to compare results generated by this universal screening to those in their study. These findings will help researchers better understand the prevalence of PPD in mothers with higher triage acuity levels and how general rates of PPD for mothers in the ED and NICU compare with those generated in past studies based on well-child checks. Eventually, she says, they would like to study whether the interventions they prescribed affected the known consequences of PPD, such as breastfeeding,  timely immunization rates and behavior outcomes.

“With appropriate care and resources,” Dr. Jarvis adds, “we’re hoping to improve the lives of these women and their families.”

In addition to Dr. Jarvis, the lead study author, Children’s co-authors include Kristen A. Breslin, M.D., M.P.H.; Gia M. Badolato, M.P.H.; James M. Chamberlain, M.D.; and Monika K. Goyal, M.D., MSCE, the study’s senior author.

When depression lingers after the NICU

distressed woman holding baby

Roughly half a million babies end up in the neonatal intensive care unit (NICU) each year in the U.S., often sending their parents on a wild emotional rollercoaster. Like other new parents, many parents feel symptoms of depression when their child leaves the NICU. For the majority, these depressive symptoms lift over time. But for others, depression can persist, affecting their well-being and relationships, including those with their new babies.

Thus far, it’s been unclear which parents are at a higher risk for this lasting depression. However, a new study led by Children’s researchers and presented at the Pediatric Academic Societies 2018 annual meeting suggests that parents whose depression lingers six months after their child’s NICU discharge tend to share certain demographic characteristics: They’re younger, have less education and care for more than one child.

“Using a validated screening tool, we found that 40 percent of parents in our analyses were positive for depression at the time their newborn was discharged from the NICU,” says Karen Fratantoni, M.D., M.P.H., a Children’s pediatrician and the lead study author. “It’s reassuring that, for many parents, these depressive symptoms ease over time. However for a select group of parents, depression symptoms persisted six months after discharge. Our findings help to ensure that we target mental health screening and services to these more vulnerable parents,” Dr. Fratantoni adds.

The study is an offshoot from “Giving Parents Support (GPS) after NICU discharge,” a large, randomized clinical trial exploring whether providing peer-to-peer parental support after NICU discharge improves babies’ overall health as well as their parents’ mental health.

Mothers of preterm and full-term infants who are hospitalized in NICUs are at risk for peripartum mood disorders, including postpartum depression. The Children’s research team sought to determine how many parents of NICU graduates experience depression and which characteristics are shared by parents with elevated depression scores.

They included 125 parents who had enrolled in the GPS clinical trial in their exploratory analyses and assessed depressive symptoms using a 10-item, validated screening tool, the Center for Epidemiological Studies Depression Scale (CES-D). Eighty-four percent of the parents were women. Nearly 61 percent of their infants were male and were born at a median gestational age of 37.7 weeks and mean birth weight of 2,565 grams. The median length of time these newborns remained in the NICU was 18 days.

When the newborns were discharged, 50 parents (40 percent) had elevated CES-D scores. By six months after discharge, that number dropped to 17 parents (14 percent).Their mean age ranged from 26.5 to 30.6 years old.

“Parents of NICU graduates who are young, have less education and are caring for other children are at higher risk for persistent symptoms of depression,” says Dr. Fratantoni. “We know that peripartum mood disorders can persist for one year or more after childbirth so these findings will help us to better match mental health care services to parents who are most in need.”

An American College of Obstetricians and Gynecologists’ committee opinion issued May 2018 calls for all women to have contact with a maternal care provider within the first three weeks postpartum and to undergo a comprehensive postpartum visit no later than 12 weeks after birth that includes screening for postpartum depression and anxiety using a validated instrument.

Brain food for preemies

Preemie Baby

Babies born prematurely – before 37 weeks of pregnancy – often have a lot of catching up to do. Not just in size. Preterm infants typically lag behind their term peers in a variety of areas as they grow up, including motor development, behavior and school performance.

New research suggests one way to combat this problem. The study, led by Children’s researchers and presented during the Pediatric Academic Societies 2018 annual meeting, suggests that the volume of carbohydrates, proteins, lipids and calories consumed by very vulnerable premature infants significantly contributes to increased brain volume and white matter development, even though additional research is needed to determine specific nutritional approaches that best support these infants’ developing brains.

During the final weeks of pregnancy, the fetal brain undergoes an unprecedented growth spurt, dramatically increasing in volume as well as structural complexity as the fetus approaches full term.

One in 10 infants born in the U.S. in 2016 was born before 37 weeks of gestation, according to the Centers for Disease Control and Prevention. Within this group, very low birthweight preemies are at significant risk for growth failure and neurocognitive impairment. Nutritional support in the neonatal intensive care unit (NICU) helps to encourage optimal brain development among preterm infants. However, their brain growth rates still lag behind those seen in full-term newborns.

“Few studies have investigated the impact of early macronutrient and caloric intake on microstructural brain development in vulnerable preterm infants,” says Katherine Ottolini, lead author of the Children’s-led study. “Advanced quantitative magnetic resonance imaging (MRI) techniques may help to fill that data gap in order to better direct targeted interventions to newborns who are most in need.”

The research team at Children’s National Health System enrolled 69 infants who were born younger than 32 gestational weeks and weighed less than 1,500 grams. The infants’ mean birth weight was 970 grams and their mean gestational age at birth was 27.6 weeks.

The newborns underwent MRI at their term-equivalent age, 40 weeks gestation. Parametric maps were generated for fractional anisotropy in regions of the cerebrum and cerebellum for diffusion tensor imaging analyses, which measures brain connectivity and white matter tract integrity. The research team also tracked nutritional data: Grams per kilogram of carbohydrates, proteins, lipids and overall caloric intake.

“We found a significantly negative association between fractional anisotropy and cumulative macronutrient/caloric intake,” says Catherine Limperopoulos, Ph.D., director of Children’s Developing Brain Research Laboratory and senior author of the research. “Curiously, we also find significantly negative association between macronutrient/caloric intake and regional brain volume in the cortical and deep gray matter, cerebellum and brainstem.”

Because the nutritional support does contribute to cerebral volumes and white matter microstructural development in very vulnerable newborns, Limperopoulos says the significant negative associations seen in this study may reflect the longer period of time these infants relied on nutritional support in the NICU.

In addition to Ottolini and Limperopoulos, study co-authors include Nickie Andescavage, M.D., Attending, Children’s Neonatal-Perinatal Medicine; and Kushal Kapse.

Developing brains are impacted, but can recover, from molecularly targeted cancer drugs

Joseph Scafidi

“The plasticity of the developing brain does make it susceptible to treatments that alter its pathways,” says Joseph Scafidi, D. O., M.S. “Thankfully, that same plasticity means we have an opportunity to mitigate the damage from necessary and lifesaving treatments by providing the right support after the treatment is over.”

One of the latest developments in oncology treatments is the advancement of molecularly targeted therapeutic agents. These drugs can be used to specifically target and impact the signaling pathways that encourage tumor growth, and are also becoming a common go to for ophthalmologists to treat retinopathy of prematurity in neonates.

But in the developing brain of a child or adolescent, these pathways are also crucial to the growth and development of the brain and central nervous system.

“These drugs have been tested in vitro, or in tumor cells, or even in adult studies for efficacy, but there was no data on what happens when these pathways are inhibited during periods when their activation is also playing a key role in the development of cognitive and behavioral skills, as is the case in a growing child,” says Joseph Scafidi, D. O., M.S., a neuroscientist and pediatric neurologist who specializes in neonatology at Children’s National Health System.

As it turns out, when the drugs successfully inhibit tumor growth by suppressing receptors, they can also significantly impact the function of immature brains, specifically changing cognitive and behavioral functions that are associated with white matter and hippocampal development.

The results appeared in Cancer Research, and are the first to demonstrate the vulnerability of the developing brain when this class of drugs is administered. The pre-clinical study looked at the unique impacts of drugs including gefitinib (Iressa), sunitib malate (Sutent) and rapamycin (Sirolimus) that target specific pathways responsible for the rapid growth and development that occurs throughout childhood.

The agents alter signaling pathways in the developing brain, including decreasing the number of oligodendrocytes, which alters white matter growth. Additionally, the agents also impact the function of specific cells within the hippocampus related to learning and memory. When younger preclinical subjects were treated, impacts of exposure were more significant. Tests on the youngest pre-clinical subjects showed significantly diminished capacity to complete cognitive and behavioral tasks and somewhat older, e.g. adolescent, subjects showed somewhat fewer deficits. Adult subjects saw little or no deficit.

“The impacts on cognitive and behavioral function for the developing brain, though significant, are still less detrimental than the widespread impacts of chemotherapy on that young brain,” Dr. Scafidi notes. “Pediatric oncologists, neuro-oncologists and ophthalmologists should be aware of the potential impacts of using these molecularly targeted drugs in children, but should still consider them as a treatment option when necessary.”

The effects are reversible

Researchers also found measurable improvements in these impaired cognitive and behavioral functions when rehabilitation strategies such as environmental stimulation, cognitive therapy and physical activity were applied after drug exposure.

“The plasticity of the developing brain does make it susceptible to treatments that alter its pathways,” says Dr. Scafidi. “Thankfully, that same plasticity means we have an opportunity to mitigate the damage from necessary and lifesaving treatments by providing the right support after the treatment is over.”

Many major pediatric oncology centers, including the Center for Cancer and Blood Disorders at Children’s National, already incorporate rehabilitation strategies such as cognitive therapy and increased physical activity to help pediatric patients return to normal life following treatment. The results from this study suggest that these activities after treatment for pediatric brain tumors may play a vital role in improving recovery of brain cognitive and behavioral function in the pediatric population.

This research was funded by grants to Dr. Scafidi from the National Brain Tumor Society, Childhood Brain Tumor Foundation and the National Institutes of Health.

Using text messages and telemedicine to improve diabetes self-management

Maureen Monaghan

Maureen Monaghan, Ph.D., C.D.E., clinical psychologist and certified diabetes educator in the Childhood and Adolescent Diabetes Program at Children’s National Health System, awarded nearly $1.6 million grant from American Diabetes Association.

Adolescents and young adults ages 17-22 with Type 1 diabetes are at high risk for negative health outcomes. If fact, some studies show that less than 20 percent of patients in this population meet targets for glycemic control, and visits to the Emergency Department for acute complications like diabetic ketoacidosis peak around the same age.

The American Diabetes Association (ADA) awarded Maureen Monaghan, Ph.D., C.D.E., clinical psychologist and certified diabetes educator in the Childhood and Adolescent Diabetes Program at Children’s National Health System, nearly $1.6 million to evaluate an innovative behavioral intervention to improve patient-provider communication, teach and help patients maintain self-care and self-advocacy skills and ultimately prepare young adults for transition into adult diabetes care, limiting the negative adverse outcomes that are commonly seen in adulthood.

Dr. Monaghan is the first psychologist funded through the ADA’s Pathway to Stop Diabetes program, which awards six annual research grants designed to spur breakthroughs in fundamental diabetes science, technology, diabetes care and potential cures. Dr. Monaghan received the Accelerator Award, given to diabetes researchers early in their careers, which will assist her in leading a behavioral science project titled, “Improving Health Communication During the Transition from Pediatric to Adult Diabetes Care.”

“Behavior is such a key component in diabetes care, and it’s wonderful that the American Diabetes Association is invested in promoting healthy behaviors,” says Dr. Monaghan. “I’m excited to address psychosocial complications of diabetes and take a closer look at how supporting positive health behavior during adolescence and young adulthood can lead to a reduction in medical complications down the road.”

During the five year study, Dr. Monaghan will recruit patients ages 17-22 and follow their care at Children’s National through their first visit with an adult endocrinologist. Her team will assess participants’ ability to communicate with providers, including their willingness to disclose diabetes-related concerns, share potentially risky behaviors like drinking alcohol and take proactive steps to monitor and regularly review glucose data.

“The period of transition from pediatric to adult diabetes care represents a particularly risky time. Patients are going through major life changes, such as starting new jobs, attending college, moving out of their parents’ homes and ultimately managing care more independently,” says Dr. Monaghan. “Behavioral intervention can be effective at any age, but we are hopeful that we can substantially help youth during this time of transition when they are losing many of their safety nets.”

Study leaders will help participants download glucose device management tools onto their smartphones and explain how to upload information from patients’ diabetes devices into the system. Participants will then learn how to review the data and quickly spot issues for intervention or follow-up with their health care provider.

Patients also will participate in behavioral telemedicine visits from the convenience of their own homes, and receive text messages giving them reminders about self-care and educational information, such as “Going out with your friends tonight? Make sure you check your glucose level before you drive.”

At the study’s conclusion, Dr. Monaghan anticipates seeing improvements in psychosocial indicators, mood and transition readiness, as well as improved diabetes self-management and engagement in adult medicine.

Mental health screenings increase in practices with hands-on support

Lee Beers

A new study suggests many more pediatricians would make mental health screenings an integral part of a child’s annual checkup if they received training and support through a proven and powerful method used to improve health care processes and outcomes.

Results of the multidisciplinary study led by Children’s National Health System and published in Pediatrics, showed screening rates improved from one percent to 74 percent during the 15-month study. A total of 10 pediatric practices and 107 individual providers in the Washington, D.C., area voluntarily participated in the study.

“This study is an important first step towards early identification of children with mental health concerns,” says Lee S. Beers, M.D., the study’s lead author. “If you identify and treat children with mental health concerns earlier, you’re going to see better outcomes.”

In this country, approximately 13 percent of youth live with a serious mental illness, but only about 20 percent of them get the help they need, according to the D.C. Collaborative for Mental Health in Pediatric Primary Care.

While many pediatricians agree that early mental health screenings are important, the researchers found that few providers were actually conducting them. In the past, primary care providers have cited a shortage of pediatric mental health providers, a lack of time, insufficient resources and lower reimbursements.

To address the lack of mental health screenings, researchers decided to test whether the Quality Improvement (QI) Learning Collaborative model, which was pioneered in the mid-1990s to scale and improve health care services, would help study participants integrate screenings into their practices.

The QI Learning Collaborative model takes a more hands-on approach than the typical “once and done” study, says Beers. Specifically, the participating primary care providers received periodic check-ins, ongoing support, monitoring and technical assistance. “We use rapid cycles of evaluation to see what’s working and what’s not working, and we keep going,” Beers says.

Dr. Beers is optimistic about how well the practices performed, adding the caveat that more information is needed about the burden it could place on already bustling pediatric practices. In addition, she says, “future research will be needed to determine whether identifying mental health issues also leads to improved access to care and outcomes for pediatric patients.”

Dr. Beers serves as medical director for Municipal and Regional Affairs at the Child Health Advocacy Institute (CHAI), part of Children’s National. CHAI is a founding member of the D.C. Healthy Communities Collaborative (DCHCC), which partnered on the study with the Georgetown University Medical Center and the Georgetown University Center for Child and Human Development.

Imaging captures obesity’s impact on the adolescent brain

Adolescent brain scan from obesity study

For the first time, a team of researchers led by Chandan Vaidya, Ph.D., chair of the Department of Psychology at Georgetown University, has used functional magnetic resonance imaging (fMRI) to capture the brain function of a small population of adolescents with obesity, both before and after bariatric surgery.

Obesity affects the whole body, from more obvious physical impacts on bones and joints to more subtle, internal impacts on organs like the brain.

For the first time, a team of researchers has used functional magnetic resonance imaging (fMRI) to capture the brain function of a small population of adolescents with obesity, both before and after bariatric surgery. The goal is to better understand the neural changes that occur when an adolescent is obese, and determine the effectiveness of interventions, such as vertical sleeve gastrectomy, at improving brain function as weight is lost.

The study, published as the November Editors’ Choice in the journal Obesity, found that executive and reward-related brain functions of study participants with obesity improved following the surgical procedure and initial weight loss.

“We’ve known for some time that severe obesity has negative consequences on some neurocognitive function areas for adults,” says Chandan Vaidya, Ph.D., chair of the Department of Psychology at Georgetown University and a senior author of the study. “But for the first time, we’ve captured fMRI evidence in young patients, and also shown that surgical intervention and the resulting weight loss can reverse some of those deficits.”

“For me, this early evidence makes a strong case that when kids are struggling with severe obesity, we need to consider surgical intervention as an option sooner in the process,” notes Evan Nadler, M.D., director of the Bariatric Surgery Program at Children’s National Health System, who also contributed to the study. “The question that remains is whether the neurocognitive function improves more if surgery, and thus weight loss, happens earlier – and is there a time factor that should help us determine when to perform a procedure that will maximize improvements?”

The preliminary study included 36 participants and was conducted using patients recruited from the Children’s National Bariatric Surgery program, one of the first children’s hospitals to achieve national accreditation by the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program.

“We asked these questions because we know that in the kids we see, their behavioral, brain, and physical health are all very closely related to one another and have an impact on each other,” adds Eleanor Mackey, Ph.D., study senior author and co-principal investigator on the National Institute of Diabetes and Digestive and Kidney Diseases grant that funded the project. “We expected that as physical health improves, we might see corresponding improvements in brain and behavior such as cognitive and school performance.”

The study also pointed out some technical and practical challenges to studying this particular young population. Anyone with a BMI greater than 50 was not able to fit within the MR bore used in the study, preventing fMRI participation by those patients.

“In addition to future studies with a larger sample size, we’d like to see if there are neuroimaging markers of plasticity differences in a population with BMI greater than 50,” says Dr. Vaidya. “Does the severity of the obesity change how quickly the brain can adapt following surgery and weight loss?”

The abstract was selected by the journal’s editors as one that provides insights into preventing and treating obesity. It was featured at the Obesity Journal Symposium during Obesity Week 2017 in Washington, D.C., as part of the Obesity Week recognition, and a digital video abstract was also released about the findings.

Improving health care for immigrant children

Olanrewaju-Falusi

Immigrant children may face multiple and complex challenges that underlie seemingly routine health concerns that bring them to clinic, says Olanrewaju Falusi, M.D., F.A.A.P.

Over the next 40 years, children of immigrant families will grow to represent one-third of residents of the United States. To help more pediatricians address the interplay between immigration and child health, a Children’s National Health System clinician helped to compile a set of case studies, resources and recommendations.

Olanrewaju Falusi, M.D., F.A.A.P., and a colleague explained these issues during their joint presentation, “Advancing health care quality for immigrant children,” during the 2017 American Academy of Pediatrics (AAP) national conference. The aim of the presentation and of their work is to help pediatricians understand the impact of immigration-related issues and unresolved immigration status on children’s mental health and well-being.

“As pediatricians, we are tasked with caring for the whole child. And, for immigrant children, there may be multiple and complex challenges that underlie seemingly routine health concerns that bring them to clinic,” says Dr. Falusi, associate medical director of municipal and regional affairs at the Child Health Advocacy Institute at Children’s National. “By more fully understanding immigrant children’s unique needs, we can help bolster their resiliency.”

Though refugees may be resettled anywhere, in fiscal year 2016 almost 7,400 unaccompanied children were released to sponsors in California, the highest of the states. In five states (California, Illinois, Massachusetts, New York, Washington state and the District of Columbia) immigration status has no bearing on a child accessing public health. Undocumented immigrants, however, are not eligible for subsidies that lower the price of health insurance. Nor can they access such federal entitlements as SNAP (formerly known as Food Stamps). Even something as basic as having a ride to a doctor’s appointment can be complicated since only one dozen states offer access to driver’s licenses regardless of immigration status.

Using the case of a child named “Pedro,” who feared deportation, Dr. Falusi and a colleague explained how immigration status impacts access to clinical care, discussed DACA, his parent’s undocumented status and explored how clinicians could support Pedro and his family.

In another scenario, Esperanza comes to clinic with her 3- and 6-year-old sons, who are afraid to leave her side. Since the family fled Honduras and settled in the United States, Esperanza worries about her older daughter’s behavioral problems in school.

“These are challenging mental health concerns to unravel because some families may be reluctant to reopen past traumas,” Dr. Falusi says. “During their flight from their home country, children can be victims of or witnesses to violence, including rape. They may have seen another person drown during a water crossing or die in arid deserts.”

Clinicians can begin such conversations simply by trying to understand why Esperanza and her children came to the United States in order to consider the range of options for appropriate clinical care, as well as possible legal services. Bridging from that more neutral starting point, the health care team could delve into her family’s experiences in Honduras. If Esperanza fears returning to Honduras, asylum may be an option if her fears are well-founded and the persecution is due to race, religion, nationality, political opinion or membership in a particular social group, Dr. Falusi says.  Additional options may include T visas and U visas for victims of certain crimes.

“We are all aware how little time there is during the clinical encounter to have such detailed conversations. Ideally, the clinician would serve as a trusted intermediary, helping the family connect with community resources in order to best address the unique social needs of immigrant children,” Dr. Falusi says.

Helping parents of babies leaving NICU cope

A study team from Children’s National tried to determine factors closely associated with poor emotional function in order to identify at-risk parents most in need of mental health support.

Nearly half of parents reported depressive symptoms, anxiety and stress when their infants were discharged from the neonatal intensive care unit (NICU), and parents who were the most anxious were the most depressed. A Children’s National Health System team presented these research findings during the 2017 American Academy of Pediatrics (AAP) national conference.

Because their infants’ lives hang in the balance, NICU parents are at particular risk for poor emotional function, including mood disorders, anxiety and distress. Children’s National Neonatologist Lamia Soghier, M.D., and the study team tried to determine factors closely associated with poor emotional function in order to identify at-risk parents most in need of mental health support.

The study team enrolled 300 parents and infants in a randomized controlled clinical trial that explored the impact of providing peer-to-peer support to parents after their newborns are discharged from the NICU. The researchers relied on a 10-item tool to assess depressive symptoms and a 46-question tool to describe the degree of parental stress. They used regression and partial correlation to characterize the relationship between depressive symptoms, stress, gender and educational status with such factors as the infant’s gestational age at birth, birth weight and length of stay.

Some 58 percent of the infants in the study were male; 58 percent weighed less than 2,500 grams at birth; and the average length of stay for 54 percent of infants was less than two weeks. Eighty-nine percent of parents who completed the surveys were mothers; 44 percent were African American; and 45 percent reported having attained at least a college degree. Forty-three percent were first-time parents.

About 45 percent of NICU parents had elevated Center for Epidemiological Studies Depression Scale (CES-D) scores.

“The baby’s gender, gestational age at birth and length of NICU stay were associated with the parents having more pronounced depressive symptoms,” Dr. Soghier says. “Paradoxically, parents whose newborns were close to full-term at delivery had 6.6-fold increased odds of having elevated CES-D scores compared with parents of preemies born prior to 28 weeks’ gestation. Stress levels were higher in mothers compared with fathers, but older parents had lower levels of stress than younger parents.”

Dr. Soghier says the results presented at AAP are an interim analysis. The longer-term PCORI-funded study continues and explores the impact of providing peer support for parents after NICU discharge.

Reducing bullying the Finnish way – in the United States

Kid being bullied

Bullying is a pervasive problem for U.S. kids. Recent studies show that between one in four to one in three children have been bullied at school. About one in 10 are victimized regularly.

Research suggests that this isn’t just harmless “kids being kids” behavior, says Marissa Smith, Ph.D., a postdoctoral fellow in behavioral pain medicine at Children’s National Health System. Bullied children have a greater risk of experiencing overall negative academic outcomes, such as greater school avoidance, decreased classroom engagement and lower academic achievement than children who aren’t bullied. They also suffer emotionally, with more depression, anxiety and withdrawal, as well as suffering physically, reporting more headaches, stomachaches and sleep difficulties.

In response to these harmful consequences, researchers in Finland in 2009 developed the KiVa Anti-Bullying Program. This school-based program combats bullying through a series of teacher-led lessons provided to students throughout the academic year that aim to shift the entire school’s ethos.

Research in Finland demonstrating the success of KiVa has encouraged school systems around the world to pilot and evaluate the KiVa program in their schools. However, Smith cautions, differing school cultures could lead to differing results.

“Compared with Finland, teachers in the United States juggle many more competing demands on their time and, at times, have fewer resources and less institutional support in fulfilling those demands,” she explains. “Consequently, it’s not clear whether a program like KiVa would be as realistic here.”

To see how implementing KiVa might differ in an American setting, Smith and colleagues helped fourth- and fifth-grade teachers at nine elementary schools in one Delaware school district roll out the program to 1,409 students during the 2013 to 2014 school year. Each teacher completed a three-hour training course at the beginning of the year – already a drastic cut from the two full days of training that is standard in Finland – due to competing demands on American teachers’ professional development time.

Delaware teachers also completed questionnaires at the start of the year about variables that might affect how well they would be able to implement the program, such as their level of professional burnout, perceived principal support, self-efficacy at teaching and perceived feasibility and efficacy of KiVa. Students completed questionnaires at the beginning and end of the academic year that measured levels of victimization and bullying.

Once a month, teachers were to give their classes standard KiVa lessons. To track what they actually completed, teachers answered online questionnaires. They also met with a graduate student once monthly to learn tips about implementing the program.

Results published online Aug. 29, 2017 in Journal of School Psychology by Smith and co-authors showed that this program accomplished its goals of significantly reducing bullying and victimization by the end of the year. Precisely how successful these measures were hinged on what instructional “dose” of the program students received, Smith says. On average, teachers provided only half of the activities that were intended to be included in each lesson. They also gave an average of 7.8 KiVa lessons out of a possible total of 10.

When Smith and colleagues assessed which teacher variables correlated with a reduction in KiVa instruction, professional burnout had the highest impact. It’s hard to say what leads teachers to experience burnout; however, Smith explains, it might be an overall symptom of U.S. teaching culture.

“Teachers are highly regarded in Finland – at the same level as doctors – but U.S. teachers are not afforded nearly the same levels of respect,” she says. “Burnout here may speak to this lack of respect. Other factors that contributed to diminished KiVa instruction include lower levels of resources and institutional support, teachers’ own degree of emotional investment in the school and teachers’ perception they actually can accomplish the things they set out to do.”

Each of these differences, Smith adds, could contribute to KiVa not being as effective in the United States as it is in Finland.

One way to improve the success of this program in the United States, the study notes, might be to distill KiVa’s tenets to the bare minimum necessary to maintain positive outcomes, allowing more efficient lessons. Additionally, outsourcing lessons to guidance counselors or other school staff versed in social and emotional topics might ease teachers’ workloads.

“Schools in the United States differ significantly from those in Finland, where this program started,” she says. “Our results suggest that supporting U.S. teachers in ways that reduce burnout could lead to better implementation and less bullying – which could lead to real and lasting improvements to their students’ lives.”

Exchanging ideas, best practices in China

Exchanging ideas

In late June, a delegation of international pediatric experts from Children’s National Health System journeyed across the world to learn about the practice of pediatric medicine in China and to exchange ideas with colleagues there. Leaders from several of Children’s key specialties joined the delegation, including:

  • Sarah Birch, D.N.P., C.P.N.P.-P.C., director, Advance Practice Nursing
  • Roberta DeBiasi, M.D., chief, Infectious Disease
  • William Gaillard, M.D., chief, Epilepsy and Neurophysiology
  • Lawrence Jung, M.D., chief, Rheumatology
  • Robert Keating, M.D., chief, Neurosurgery
  • Peter Kim, M.D., vice president, Sheikh Zayed Institute for Pediatric Surgical Innovation, associate surgeon-in-chief
  • Yang Liu, Ph.D., director, Center for Cancer and Immunology Research
  • Michael Mintz, Psy.D., developmental psychologist
  • Pamela Mudd, M.D., otolaryngologist
  • Xiaoyan Song, Ph.D., director, Infection Control/Epidemiology

The group, led by Drs. Keating and Gaillard, traveled to China with Children’s Outreach Coordinator John Walsh, whose longtime connections and close familiarity with the pediatric medical community in Hangzhou and Shanghai made the collaboration possible. The team toured several of the largest children’s hospitals in country, including The Children’s Hospital of Zhejiang University School of Medicine in Hangzhou and Shanghai Children’s Medical Center, connecting with pediatric specialists there.

“Some of the most important parts of this trip were the opportunities to exchange ideas and solidify long term relationships that will allow us to work closely with our peers in China as they develop their pediatric programs. The potential is tremendous for unique collaborations between our teams and theirs for research and the development of clinical care improvements for children,” said Roger Packer, M.D., senior vice president of the Center for Neuroscience and Behavioral Medicine, who joined the delegation in Beijing.

A keynote lecture and more at the 3rd China International Forum on Pediatric Development

The delegation also was honored with an invitation to participate in the 3rd China International Forum on Pediatric Development. The forum is one of the largest pediatric focused meetings in the country and is led by all the major children’s hospitals in China, including those in Beijing and Shanghai. Close to 4,000 pediatricians attended the meeting, and presenters included esteemed international leaders in pediatric medicine from around the world.

Dr. Packer delivered one of the opening keynote lectures, entitled, “Translation of molecular advances into care: the challenge ahead for children’s hospitals.” His talk focused on the tremendous promise and significant challenges posed by the latest scientific advances, through the lens of a neurologist.

“Across the world, we are looking at the same challenges: How can we use scientific advances to find better outcomes? How can we financially support the new types of interventions made possible by these molecular biologics insights when they can cost millions of dollars for one patient?”

“There’s palpable excitement that these new developments will give us potential therapies we never dreamed about before, ways to reverse what we initially thought was irreversible brain damage, ways to prevent severe illnesses including brain tumors, but the issue is how to turn this promise into reality. That’s a worldwide issue, not simply a single country’s issue,” he continued.

He also flagged mental health and behavioral health as a crucial, universal challenge in need of addressing on both sides of the Pacific.

The Children’s National delegation, including Drs. DeBiasi, Song, Keating, Gaillard and Packer were also honored to share their insight in a series of specialty-specific breakout sessions at the Forum.

Overall, the long journey opened a dialogue between Children’s National and pediatric care providers in China, paving the way for future discussion about how to learn from each other and collaborate to enhance all institutions involved.
