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.”

Missed opportunities for STI screening in the ED

Emergency Department Check in

Researchers found that even though young women with pelvic inflammatory disease (PID) are at increased risk for also being infected with syphilis and human immunodeficiency virus (HIV), few adolescent females diagnosed with PID in U.S. pediatric emergency departments (ED) undergo laboratory tests for HIV or syphilis.

Sexually transmitted infections (STIs) are on the rise in the U.S., reaching unprecedented highs in recent years for the three most common STIs reported in the nation: chlamydia, gonorrhea and syphilis. Nearly half of the 20 million new STI cases each year are in adolescents aged 15 to 24, according to the Department of Health & Human Services. In particular, about two in five sexually active teen girls has an STI.

These infections can be far more than an embarrassing nuisance; some can cause lifelong infertility. According to the Centers for Disease Control and Prevention, undiagnosed STIs cause infertility in more than 20,000 women each year.

A new retrospective cohort study led by researchers at Children’s National Health System and published online July 24, 2018, in Pediatrics shines a stark spotlight on missed opportunities for diagnosis. Researchers found that even though young women with pelvic inflammatory disease (PID) are at increased risk for also being infected with syphilis and human immunodeficiency virus (HIV), few adolescent females diagnosed with PID in U.S. pediatric emergency departments (ED) undergo laboratory tests for HIV or syphilis.

A team of Children’s researchers reviewed de-identified data from the Pediatric Health Information System, a database that aggregates encounter-level data from 48 children’s hospitals across the nation. From 2010 through 2015, there were 10,698 diagnosed cases of PID among young women aged 12 to 21. Although HIV and syphilis screening rates increased over the study period, just 27.7 percent of these women underwent syphilis screening, 22 percent were screened for HIV, and only 18.4 percent underwent lab testing for both HIV and syphilis.

Screening rates varied dramatically by hospital, with some facilities screening just 2 percent of high-risk young women while others tested more than 60 percent.

HIV screening was more likely to occur among:

  • Women admitted to the hospital, compared with those discharged from the ED (adjusted odds ratio [aOR] of 7.0)
  • Uninsured women, compared with women with private insurance (1.6 aOR)
  • Non-Latino African American women, compared with non-Latino white women (1.4 aOR)
  • Women seen at small hospitals with fewer than 300 beds (1.4 aOR)
  • Women with public insurance compared with women with private insurance (1.3 aOR)
  • 12-year-olds to 16-year-olds, compared with older adolescents (1.2 aOR)

Syphilis screening was more likely to occur for:

  • Women admitted to the hospital (4.6 aOR)
  • Non-Latino African American women (1.8 aOR)
  • Uninsured women (1.6 aOR)
  • Women with public insurance (1.4 aOR)
  • 12-year-olds to 16-year-olds (1.1 aOR)

“We know that 20 percent of the nearly 1 million cases of PID that are diagnosed each year occur in young women, with the majority of diagnoses made in EDs. It is encouraging that HIV and syphilis screening rates for women with PID increased over the study period. However, our findings point to missed opportunities to safeguard young women’s reproductive health,” says Monika K. Goyal, M.D., M.S.C.E., assistant professor of Pediatrics and Emergency Medicine and the study’s senior author. “Such discrepancies in screening across the 48 hospitals we studied underscore the need for a standardized approach to sexually transmitted infection (STI) screening.”

Untreated STIs can cause PID, an infection of a woman’s reproductive organs that can complicate her ability to get pregnant and also can cause infertility. Since 2006, the Centers for Disease Control and Prevention (CDC) has recommended that all women diagnosed with PID be tested for HIV. The CDC’s treatment guidelines also recommend screening people at high risk for syphilis.

“Syphilis infection rates have steadily increased each year, and it is now most prevalent among young adults,” Dr. Goyal says. “Future research should examine how STI screening can be improved in emergency departments, especially since adolescents at high risk for STIs often access health care through EDs. We also should explore innovative approaches, including electronic alerts and shared decision-making to boost STI screening rates for young women.”

Bladder cancer’s unique bacterial “fingerprint”

Michael H. Hsieh, M.D., Ph.D.

Michael H. Hsieh, M.D., Ph.D.

Decades ago, researchers thought that the native bacteria scattered throughout the human body—such as in the gut, the oral cavity and the skin—served little useful purpose. This microbiota, whose numbers at least match those of the cells in the body they live on and in, were considered mostly harmless hitchhikers.

More recently, research has revealed that these natural flora play key roles in maintaining and promoting health. In addition, studies have shown that understanding what a “typical” microbiome looks like and how it might change over time can provide an early warning system for some health conditions, including cancer.

Now, a small, multi-institutional study conducted in experimental models suggests that as bladder cancer progresses, it appears to be associated with a unique bacterial fingerprint within the bladder—a place thought to be bacteria-free except in the case of infection until just a few years ago. The finding opens the possibility of a new way to spot the disease earlier.

Bladder cancer is the fourth-most common malignancy among U.S. men but, despite its prevalence, mortality rates have remained stubbornly high. Patients often are diagnosed late, after bladder cancer has advanced. And, it remains difficult to discern which patients with non-invasive bladder cancer will go on to develop muscle-invasive disease.

Already, researchers know that patients with grade 4 oral squamous cell carcinoma, women with increasingly severe grades of cervical cancer and patients with cirrhosis who develop liver cancer have altered oral, vaginal and gut microbiomes, respectively.

New technological advances have led to identification of a diverse community of bacteria within the bladder, the urinary microbiome. Leveraging these tools, a research team that includes Children’s National Health System investigators studied whether an experimental model’s urinary bacterial community changed as bladder cancer progressed, evolving from a microbiome into a urinary “oncobiome.”

To test the hypothesis, the research team led by Michael H. Hsieh, M.D., Ph.D., a Children’s urologist, exposed an experimental model of bladder cancer to a bladder-specific cancer-causing agent, n-butyl-n-(4-hydroxybutyl) nitrosamine (BBN). Bladder cancers induced by BBN closely resemble human cancers in tissue structure at the microscopic level and by gene expression analyses. Ten of the preclinical models received a .05 percent concentration of BBN in their drinking water over five months and were housed together. Ten other experimental models received regular tap water and shared a separate, adjacent cage.

Researchers collected urine samples ranging from 10 to 100 microliters at the beginning of the longitudinal study, one week after it began, then once monthly. They isolated microbial DNA from the urine and quantified it to determine how much DNA was microbial. All of the bladders from experimental models exposed to BBN and two bladders from the control group were analyzed by a pathologist trained in bladder biology.

According to the study published online July 5, 2018, by the biology preprint server Biorxiv, they found a range of pathologies:

  • Five of the experimental models that received BBN did not develop cancer but had histology consistent with inflammation. Three had precancer on histology: urothelial dysplasia, hyperplasia or carcinoma in situ. Two developed cancer: invasive urothelial carcinomas, one of which had features of a squamous cell carcinoma.
  • The experimental model that developed invasive carcinoma had markedly different urinary bacteria at baseline, with Rubellimicrobium, a gram negative organism found in soil that has not been associated with disease previously, Escherichia and Kaistobacter, also found in soil, as the most prominent bacteria. By contrast, in the other experimental models the most common urinary bacteria were Escherichia, Prevotella, Veillonella, Streptococcus, Staphylococcus and Neisseria.
  • By month four, the majority of experimental models exposed to BBN had significantly higher proportion of Gardnerella and Bifidobacterium compared with their control group counterparts.

“Closely analyzing the urinary bacterial community among experimental models exposed to BBN, we saw distinct differences in microbial profiles by month four that were not present in earlier months,” Dr. Hsieh says. “While Gardnerella is associated with the development of cancer, Bifidobacterium has been shown to exert antitumor immunity, and its increasing abundance points to the need for additional research to understand its precise role in oncogenesis.”

Dr. Hsieh adds that although the study is small, its findings are of significance to children who are prone to developing urinary tract infections (UTIs), including children with spina bifida, due to the association between UTIs and bladder cancer. “This work is important because it not only suggests that the urinary microbiome could be used to diagnose bladder cancer, but that it could also perhaps predict cancer outcomes. If the urinary microbiome contributes to bladder carcinogenesis, it may be possible to favorably change the microbiome through antibiotics and/or probiotics in order to treat bladder cancer.”

In addition to Dr. Hsieh, co-authors include Catherine S. Forster, M.D., M.S., and Crystal Stroud, of Children’s National; James J. Cody, Nirad Banskota, Yi-Ju Hsieh and Olivia Lamanna, of the Biomedical Research Institute; Dannah Farah and Ljubica Caldovic, of The George Washington University; and Olfat Hammam, of Theodor Bilharz Research Institute.

Lenore Jarvis

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.”

Tonya Kinlow

The Child Health Advocacy Institute at Children’s National Health System held its first School Health Symposium, designed to strengthen relationships between the education and health care sectors. Led by Tonya Vidal Kinlow, M.P.A., vice president of Community Engagement, Advocacy and Community, Children’s National welcomed more than 150 regional health and education partners, community members and Children’s National staff to support the mission of helping kids grow up stronger.

In a day of panel discussions and breakout sessions, education, government and health professionals tackled the many societal challenges children face. The panel discussions at this year’s symposium focused on the following topics:

  • Caring for the whole child using a trauma-informed approach
  • Children’s National regional school-based programs
  • Local government role in school health
  • How a health system advocates for school health
  • How organizations are working with schools to address the social determinants of health

Participants also had the option to attend one of the following breakout sessions:

  • Mental wellness & self-care for school and health care professionals
  • School-based research: engaging families, empowering students
  • How an anchor institution is addressing the social determinants of health
  • School health legislation update

Outreach programs focused on strong community partnerships were recognized for serving diverse communities including infants and their caregivers, primary care clinicians, high school students, child care providers and teachers. Three programs were chosen as recipients for the Community Health Improvement Award through an application process where a panel of judges with expertise in public health and policy evaluated against an established criteria set.

“Our Community Health Improvement Awards recognize all efforts to conduct community outreach programs and shape public policies that benefit children and families in the Washington D.C.  area,” says Kurt Newman, M.D., president and CEO of Children’s National. “The award also recognizes the physicians and clinicians here at Children’s who go above and beyond to provide quality care to kids and their families.”

This year’s recipients actively play a role in contributing to school health:

The School Health Symposium was followed by a networking reception to allow participants an opportunity to connect with colleagues and discuss the sessions.

Making the grade: Children’s National is nation’s Top 5 children’s hospital

Children’s National rose in rankings to become the nation’s Top 5 children’s hospital according to the 2018-19 Best Children’s Hospitals Honor Roll released June 26, 2018, by U.S. News & World Report. Additionally, for the second straight year, Children’s Neonatology division led by Billie Lou Short, M.D., ranked No. 1 among 50 neonatal intensive care units ranked across the nation.

Children’s National also ranked in the Top 10 in six additional services:

For the eighth year running, Children’s National ranked in all 10 specialty services, which underscores its unwavering commitment to excellence, continuous quality improvement and unmatched pediatric expertise throughout the organization.

“It’s a distinct honor for Children’s physicians, nurses and employees to be recognized as the nation’s Top 5 pediatric hospital. Children’s National provides the nation’s best care for kids and our dedicated physicians, neonatologists, surgeons, neuroscientists and other specialists, nurses and other clinical support teams are the reason why,” says Kurt Newman, M.D., Children’s President and CEO. “All of the Children’s staff is committed to ensuring that our kids and families enjoy the very best health outcomes today and for the rest of their lives.”

The excellence of Children’s care is made possible by our research insights and clinical innovations. In addition to being named to the U.S. News Honor Roll, a distinction awarded to just 10 children’s centers around the nation, Children’s National is a two-time Magnet® designated hospital for excellence in nursing and is a Leapfrog Group Top Hospital. Children’s ranks seventh among pediatric hospitals in funding from the National Institutes of Health, with a combined $40 million in direct and indirect funding, and transfers the latest research insights from the bench to patients’ bedsides.

“The 10 pediatric centers on this year’s Best Children’s Hospitals Honor Roll deliver exceptional care across a range of specialties and deserve to be highlighted,” says Ben Harder, chief of health analysis at U.S. News. “Day after day, these hospitals provide state-of-the-art medical expertise to children with complex conditions. Their U.S. News’ rankings reflect their commitment to providing high-quality care.”

Stricter state firearms laws can save children’s lives

In a new study presented at the Pediatric Academic Societies (PAS) 2018 annual meeting, Children’s researchers find that states with stricter firearm laws have lower rates of firearm-related deaths in children. The same cross-sectional analyses also found that states with laws that mandate universal background checks prior to firearm and ammunition purchases were associated with lower rates of firearm-related mortality in children, compared with states that lack these laws.

“Injuries due to firearms are the nation’s third-leading cause of pediatric death,” says Monika Goyal, M.D., M.S.C.E., director of research in the Division of Emergency Medicine and Trauma Services at Children’s National Health System and lead author of the research paper. “Firearm legislation at the state level varies significantly. Our findings underscore the need for further investigation of which types of state-level firearm legislation most strongly correlate with reduction in pediatric injuries and deaths.”

The research team analyzed data from the 2015 Web-based injury statistics query and reporting system maintained by the Centers for Disease Control and Prevention to measure the association between Brady Gun Law Scores – a scorecard that evaluates how strict firearms legislation and policies are in all 50 states – and state-based rates of firearm-related death among children aged 21 years and younger.

In 2015, 4,528 children died from firearm-related injuries. Eighty-seven percent were male; 44 percent were non-Latino black; their mean age was 18.

State-specific firearm-related mortality rates among children were as low as 0 per 100,000 to as high as 18 per 100,000. Median mortality rates were lower among the 12 states requiring universal background checks for firearm purchase at 3.8 per 100,000 children compared with 5.7 per 100,000 children in states that did not require background checks. Similarly, the five states with this requirement had a lower median mortality rate, 2.3 per 100,000 children, when compared with states that did not require background checks for ammunition purchase, 5.6 per 100,000 children.

“Newtown. Orlando. Las Vegas. Parkland. Those are among the mass shootings that have occurred across the nation in recent years. While these tragedies often are covered heavily by the news media, they represent a subset of overall pediatric injuries and deaths due to firearms. Pediatric firearm-related injuries are a critical public health issue across the U.S.,” Dr. Goyal adds.

“Pediatricians have helped to educate parents about other public health concerns, such as the danger posed by second-hand exposure to tobacco smoke or non-use of seat belts and car seats. In addition to presenting our most recent study results, members of our research group also hosted a workshop at PAS aimed at inspiring pediatric clinicians to similarly tackle this latest public health challenge and to advocate for firearm safety,” she says.

In addition to Dr. Goyal, study co-authors include Gia Badolato; Shilpa Patel, M.D.; Sabah Iqbal; Katie Donnelly, M.D.; and Kavita Parikh, M.D., M.S.H.S.

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.

Presidnet's Award for Innovation in Research

President’s Award highlights innovative work by early-career researchers

Presidnet's Award for Innovation in Research

As part of Research and Education Week 2018, two Presidential awardees were recognized for their research contributions, Catherine “Katie” Forster, M.D., M.S., and Nathan Anthony Smith, Ph.D.

Catherine “Katie” Forster, M.D., M.S., and Nathan Anthony Smith, Ph.D., received the President’s Award for Innovation in Research honoring their respective research efforts to explore an understudied part of the microbiome and to shed light on an underappreciated player in nerve cell communication.

Drs. Forster and Smith received their awards April 19, 2018, the penultimate day of Research and Education Week 2018, an annual celebration of the excellence in research, education, innovation and scholarship that takes place at Children’s National Health System. This year marks the fifth time the President’s Award honor has been bestowed to Children’s faculty.

Dr. Forster’s work focuses on preventing pediatric urinary tract infections (UTIs). Frequently, children diagnosed with illnesses like spina bifida have difficulty urinating on their own, and they often develop UTIs. These repeated infections are frequently treated with antibiotics which, in turn, can lead to the child developing antibiotic-resistant organisms.

“The majority of the time if you culture these children, you’ll grow something. In a healthy child, that culture would indicate a UTI,” Dr. Forster says. “Children with neurogenic bladder, however, may test positive for bacteria that simply look suspect but are not causing infection. Ultimately, we’re looking for better ways to diagnose UTI at the point of care to better personalize antibiotic treatment and limit prescriptions for children who do not truly need them.”

Powered by new sequencing techniques, a research group that includes Dr. Forster discovered that the human bladder hosts a significant microbiome, a diverse bacterial community unique to the bladder. Dr. Forster’s research will continue to characterize that microbiome to determine how that bacterial community evolves over time and whether those changes are predictable enough to intervene and prevent UTIs.

“Which genes are upregulated in Escherichia coli and the epithelium, and which genes are upregulated by both in response to each other? That can help us understand whether genes being upregulated are pathogenic,” she adds. “It’s a novel and exciting research area with significant public health implications.”

Smith’s work focuses on the role of astrocytes, specialized star-shaped glial cells, in modulating synaptic plasticity via norepinephrine. Conventional thinking describes astrocytes as support cells but, according to Smith, astrocytes are turning out to be more instrumental.

Norepinephrine, a neurotransmitter that plays an essential role in attention and focus, is released by a process known as volume transmission, which is a widespread release of a neurotransmitter at once, says Smith, a principal investigator in Children’s Center for Neuroscience Research. Astrocytes, which outnumber neurons in the brain, are strategically and anatomically located to receive this diffuse input and translate it into action to modulate neural networks.

“We hypothesize that astrocytes are integral, functional partners with norepinephrine in modulating cortical networks,” Smith adds. “Since astrocytes and norepinephrine have been implicated in many central nervous system functions, including learning and attention, it is critical to define mechanistically how astrocytes and norepinephrine work together to influence neural networks. This knowledge also will be important for the development of novel therapeutics to treat diseases such as attention deficit hyperactivity disorder and epilepsy.”

“I am honored that Children’s National Health System is among the 12 universities and health systems around the nation selected to work collaboratively to identify solutions to lower pediatric deaths and injuries due to firearms,” Dr. Goyal says. “This grant will expand the nation’s research capacity on this important subject area and will power the next wave of research to inform policy at the state and national level.”

Dr. Goyal is a member of Children’s firearms research work group which has published or presented at academic meetings on topics that include efforts to reduce pediatric firearm-related injuries and the pivotal role pediatricians can play in reducing the burden of firearm-related injuries among children.

Faculty from Ann & Robert H. Lurie Children’s Hospital of Chicago/Northwestern University, Arizona State University, Brown University, Children’s National Health System, Columbia University, Harvard University, Medical College of Wisconsin, Michigan State University, University of Colorado, University of Michigan, University of Pennsylvania and University of Washington make up the Firearm-Safety Among Children & Teens Consortium (FACTS). The initiative is co-led by Rebecca Cunningham, M.D., and Marc Zimmerman, Ph.D., of the University of Michigan.

In addition to tapping the expertise of scientists and researchers who specialize in criminal justice, emergency medicine, pediatrics, psychology, public health and trauma surgery, FACTS will include a stakeholder group that includes teachers, parent groups, gun owners, firearm safety trainers and law enforcement partners.

The five-year grant will produce a number of deliverables, including:

  • A research agenda for the field of pediatric firearm injury
  • Generating preliminary data through five small pilot projects that focus on topics such as the epidemiology of pediatric firearm injuries and prevention of firearm injuries
  • A data archive on childhood firearm injury
  • Training for the next generation of researchers, including postdoctoral trainees and graduate students

Financial support for this research was provided by the National Institute of Child Health & Human Development under award number R24HD087149.

New method may facilitate childhood respiratory research

Gustavo Nino

“The use of CRC is a potentially powerful translational approach to shed light on the molecular mechanisms that control airway epithelial immune responses in infants and young children. This novel approach enables us to study the origins of respiratory disease and its chronic progression through childhood and beyond,” observes Gustavo Nino, M.D., a Children’s pulmonologist and study senior author.

A new method perfected by a team at Children’s National Health System may help expand research into pulmonary conditions experienced by infants and children, an understudied but clinically important age group. The study describing the new technique was published in the December 2017 print edition of Pediatric Allergy and Immunology.

Using conditionally reprogrammed cells (CRCs), a technique that enables indefinite proliferation of cells in the lab, the team was able to produce cell cultures that have a number of advantages over standard cultures and that may make it easier and more efficient to conduct research into pediatric respiratory immune responses.

The epithelial cells that line human airways are crucial in controlling immune responses to viruses, allergens and other environmental factors. The function and dysfunction of these airway epithelial cells (AECs) play a key role in asthma, cystic fibrosis and other pulmonary conditions, many of which begin in early life.

To generate enough of these cells for research, scientists culture AECs from primary nasal and bronchial cell samples. Cells derived from adults have fueled research leading to new therapies and the discovery of key biomarkers. But little comparable research has been conducted in infants. Airway sampling in premature infants has not been reported, likely to due to airway size limitations and underlying comorbidities. Similarly, sampling in infants is limited by the need for bronchoscopy and sedation.

“A major barrier has been the lack of a good system to culture epithelial cells, since airway sampling in infants and children is a challenge,” says co-lead author, Geovanny F. Perez, M.D., co-director of Children’s Severe Bronchopulmonary Dysplasia Program. “We needed a better way to culture cells in this age group.”

While primary AECs do not survive long in the lab, that hurdle was recently overcome by a process that generates CRCs from the primary AECs of adults, making it possible to quickly generate cell cultures from specimens.

In this study, the Children’s team adapted that approach, producing CRCs from primary AECs of neonates and infants. The CRC induction successfully enabled AEC cultures from infants born prematurely and from bronchial specimens of young children.

“A major barrier has been the lack of a good system to culture epithelial cells, since airway sampling in infants and children is a challenge,” says co-lead author, Geovanny F. Perez, M.D., co-director of Children’s Severe Bronchopulmonary Dysplasia Program. “We needed a better way to culture cells in this age group.”

“We found that the CRCs have longer cell life and greater proliferation ability than standard cultures of epithelial cells. They preserved their original characteristics even after multiple experiments. And, they presented an innate immune response similar to that seen in primary human epithelial cells during viral respiratory responses in children,” says Dr. Perez.

“The use of CRC is a potentially powerful translational approach to shed light on the molecular mechanisms that control airway epithelial immune responses in infants and young children. This novel approach enables us to study the origins of respiratory disease and its chronic progression through childhood and beyond,” observes Gustavo Nino, M.D., a Children’s pulmonologist and study senior author.

The authors note that further studies are needed to define more precisely the differences and similarities in the immune responses of CRC and non-CRC derived from primary AEC. However, they conclude that CRC represents a new, effective method to study AEC innate immune responses in infants.

In addition to Drs. Perez and Nino, Children’s Center for Genetic Medicine Research co-authors include Co-Lead Author S. Wolf; Lana Mukharesh; Natalia Isaza Brando, M.D.; Diego Preciado, M.D., Ph.D.; Robert J. Freishtat, M.D., M.P.H.; Dinesh Pillai, M.D.; and M. C. Rose.

Funding will help uncover immune system differences that trigger food allergies

Adora Lin

“When it comes to food allergies, we really don’t know how they develop. We don’t know how to best differentiate between a child who can safely eat a potential allergen, like peanuts, compared with a child who cannot safely eat peanuts.” says Adora A. Lin, M.D., Ph.D.

Adora A. Lin, M.D., Ph.D., an attending physician in Children’s department of Allergy and Immunology, was awarded $240,000 to improve understanding of how children’s immune systems tolerate or react to certain food allergens – sometimes triggering a cascade of side effects that can be fatal.

The three-year American Academy of Allergy, Asthma & Immunology (AAAAI) Foundation award will underwrite Dr. Lin’s ongoing research into the regulation of the antibody Immunoglobulin E (IgE), which plays a pivotal role in these allergic responses.

“Our immune system maintains a delicate balance, working just enough to ward off potential invaders and pathogens, but not so much that it triggers problems of its own making,” Dr. Lin says. “When it comes to food allergies, we really don’t know how they develop. We don’t know how to best differentiate between a child who can safely eat a potential allergen, like peanuts, compared with a child who cannot safely eat peanuts.”

Food allergies have become a growing problem and affect about 1 in 13 U.S. children, or about two per classroom. Food items such as eggs, milk, peanuts, tree nuts, soy and wheat trigger allergic reactions that can include itching, swelling, hives and difficulty breathing. As children’s immune systems react to exposure to such allergens, their B-cells produce IgE antibodies.

Apart from avoiding these foods and carrying rescue medications, which must be used immediately after accidental exposure, there is no way to treat food allergies effectively. That makes it essential to better understand how the immune system works in order to innovate new and better food allergy treatments and diagnostics.

Dr. Lin’s work involves isolating immune cells from blood samples, culturing them and stimulating an immune response to known food allergy triggers. B-cells make IgE, but additional clarity is needed about what turns on the “make IgE” signal as well as which signals indicate it’s time to stop making IgE. Ultimately, the aim is to identify biomarkers that are akin to the “check engine” light that illuminates to warn of a potential problem long before a car stalls in traffic.

“I’m very excited about this funding,” Dr. Lin adds. “Our field has done an exceptional job with clinical work to help children with food allergies. This award recognizes the importance of the mechanistic side of the equation. I’m excited to help make that contribution to the research.”

As it stands now, blood tests are sensitive to food-related IgE, but are not specific. Only 30 to 55 percent of children who have IgE to common food allergens have an allergic reaction after eating the food, which means that 45 to 70 percent are merely sensitized and could tolerate eating the food. Current tests cannot distinguish between sensitized and allergic children.

“Our hope is to identify biomarkers that would serve as the ‘check engine’ light that tell us in advance which child’s immune system will react strongly to that food. Right now, there is no way to tell. This project will help uncover those differences,” she says.

Dr. Lin was one of three recipients of the AAAAI Foundation’s faculty development award, which was presented during a March 3, 2018, award ceremony held during the organization’s business meeting.

ER Nurse

An unexpected discovery in a central line

ER Nurse

About a year and a half ago, a 6-year-old boy arrived at Children’s Emergency Department after accidently removing his own gastrointestinal feeding tube. He wasn’t a stranger to Children’s National Health System: This young patient had spent plenty of time at the hospital since birth. Diagnosed in infancy with an intestinal pseudo-obstruction, a rare condition in which his bowels acted as if there were a blockage even though one was not present, parts of his intestine died and had been removed through multiple surgeries.

Because of this issue and associated health problems, at 4 years old he had a central line placed in a large vein that leads to his heart. That replaced other central lines placed in his neck earlier after those repeatedly broke. This latest central line in his chest als0 had frequent breaks. It also had become infected with multidrug-resistant Klebsiella bacteria two years before he was treated at Children’s National for inadvertently removing his feeding tube.

On that day, he seemed otherwise well. His exam was relatively unremarkable, except for a small leak in his central line and a slight fever. Those findings triggered cultures taken both from blood flowing through his central line and the surrounding skin.

“No one expected him to grow anything from these cultures, especially from a child who looked so healthy,” explains Madan Kumar, a fellow in Children’s division of Pediatric Infectious Disease and a member of the child’s care team. But a mold grew prolifically. Further investigation from a sample sent to the National Institutes of Health showed that it was a relatively new species known as Mucor velutinosus.

Because such an infection had never been reported in a child whose immune system wasn’t extremely compromised from cancer, Kumar and team decided to publish a case report. The study appeared online Jan. 24, 2018, in the Journal of the Pediatric Infectious Diseases Society.

Kumar notes that this patient faced myriad challenges. Not only did he have a central line, but the line also had numerous problems, necessitating fixes that could increase the chance of infection. Additionally, because of his intestinal issues, he had a chronic problem with malabsorption of nutrients. Patients with this issue often are treated liberally with antibiotics. Although this intervention can kill “bad” bacteria that can cause an infection, they also knock out “good” bacteria that keep other microorganisms – like fungi – in check. On top of all of this, the patient was receiving a nutrient-rich formula in his central line to boost his caloric intake, yet another factor associated with infections.

Patients who develop this specific fungal infection are overwhelmingly adults who are immunocompromised, Kumar explains, including those with diabetes, transplant recipients, patients with cancer and those who have abnormally low concentrations of immune cells called neutrophils in their blood. The only children who tend to get this infection are preterm infants of very low birth weight who haven’t yet developed a robust immune response.

Because there was only one other published case report about a child with M. velutinosus – a 1-year-old with brain cancer who had undergone a bone marrow transplant – Kumar notes that he and colleagues were at a loss as to how best to treat their patient. “There’s a paucity of literature on what to do in a case like this,” he says.

Fortunately, the treatment they selected was successful. As soon as the cultures came back positive for this mold, the patient went on a three-week course of an antifungal drug known as amphotericin B. Surgeons also removed his infected central line and placed a new one. These efforts cured the patient’s infection and prevented it from spreading and potentially causing the multi-organ failure associated with these types of infections.

This case taught Kumar and colleagues quite a bit – knowledge that they wanted to share by publishing the case report. For example, it reinforces the importance of central line care. It also highlights the value of thoroughly investigating potential problems in a patient with risk factors, even one who appears otherwise healthy.

Finally, Kumar adds, the case emphasizes the importance of good antibiotic stewardship, which can help prevent patients from developing sometimes deadly secondary infections like this one. “This is not an organism that you see growing in a 6-year-old very often,” he says. “The fact that we saw it here speaks to the need to be judicious with broad-spectrum antibiotics so that we have a number of therapeutic options should we see unusual cases like this one.”

STAT Madness

Voters select Children’s National innovation as runner-up in national competition

STAT Madness

Facial recognition technology developed and tested by researchers with the Sheikh Zayed Institute for Pediatric Surgical Innovation and Rare Disease Institute at Children’s National was the runner-up in this year’s STAT Madness 2018 competition.

Facial recognition technology developed and tested by researchers with the Sheikh Zayed Institute for Pediatric Surgical Innovation and Rare Disease Institute at Children’s National was the runner up in this year’s STAT Madness 2018 competition. Garnering more than 33,000 overall votes in the bracket-style battle that highlights the best biomedical advances, the Children’s National entry survived five rounds and made it to the championship before falling short of East Carolina University’s overall vote count.

Children’s entry demonstrates the potential widespread utility of digital dysmorphology technology to diverse populations with genetic conditions. The tool enables doctors and clinicians to identify children with genetic conditions earlier by simply taking the child’s photo with a smartphone and having it entered into a global database for computer analyses.

The researchers partnered with the National Institutes of Health National Human Genome Research Institute and clinicians from 20 different countries to acquire pictures from local doctors for the study. Using the facial analysis technology, they compared groups of Caucasians, Africans, Asians and Latin Americans with Down syndrome, 22q11.2 deletion syndrome (also called DiGeorge syndrome) and Noonan syndrome to those without it. Based on more than 125 individual facial features, they were able to correctly identify patients with the condition from each ethnic group with more than a 93 percent accuracy rate. Missed diagnoses of genetic conditions can negatively impact quality of life and lead to premature death.

Children’s National also was among four “Editor’s Pick” finalists, entries that span a diverse range of scientific disciplines. Journalists at the digital publication STAT pored through published journal articles for 64 submissions in the single-elimination contest to honor a select group of entries that were the most creative, novel, and most likely to benefit the biomedical field and the general public.

Each year, 1 million children are born worldwide with a genetic condition that requires immediate attention. Because many of these children experience serious medical complications and go on to suffer from intellectual disability, it is critical that doctors accurately diagnose genetic syndromes as early as possible.

“For years, research groups have viewed facial recognition technology as a potent tool to aid genetic diagnosis. Our project is unique because it offers the expertise of a virtual geneticist to general health care providers located anywhere in the world,” says Marius George Linguraru, D.Phil., M.A., M.S., a Sheikh Zayed Institute for Pediatric Surgical Innovation principal investigator who invented the technology. “Right now, children born in under-resourced regions of the U.S. or the world can wait years to receive an accurate diagnosis due to the lack of specialized genetic expertise in that region.”

In addition to providing patient-specific benefits, Marshall Summar, M.D., director of Children’s Rare Disease Institute that partners in the facial recognition technology research, says the project offers a wider societal benefit.

“Right now, parents can endure a seemingly endless odyssey as they struggle to understand why their child is different from peers,” says Dr. Summar. “A timely genetic diagnosis can dispel that uncertainty and replace it with knowledge that can speed patient triage and deliver timely medical interventions.”

X-linked genes help explain why boys of all ages face higher respiratory risk

chromosome

A multi-institution research team that includes Children’s National Health System attempted to characterize gender-based epigenomic signatures in the human airway early in children’s lives with a special attention to defining DNA methylation patterns of the X chromosome.

Human airways already demonstrate gender-based differences in DNA methylation signatures at birth, providing an early hint of which infants may be predisposed to develop respiratory disorders like asthma later in life, a research team reports in a paper published online April 3, 2018, in Scientific Reports.

It’s clear that boys and young men are more likely to develop neonatal respiratory distress syndrome, bronchopulmonary dysplasia, viral bronchiolitis, pneumonia, croup and childhood asthma. Unlike boys, girls have an additional copy of the X chromosome, which is enriched with immune-related genes, some of which play key roles in the development of respiratory conditions. Methylation prevents excessive gene activity in X-linked genes, however much remains unknown about how this process influences infants’ risk of developing airway diseases.

A multi-institution research team that includes Children’s National Health System attempted to characterize gender-based epigenomic signatures in the human airway early in children’s lives with a special attention to defining DNA methylation patterns of the X chromosome.

“It’s clear as we round in the neonatal intensive care unit that baby boys remain hospitalized longer than girls and that respiratory ailments are quite common. Our work provides new insights about gender differences in airway disease risk that are pre-determined by genetics,” says Gustavo Nino, M.D., a Children’s pulmonologist and the study’s senior author.

“Characterizing early airway methylation signatures holds the promise of clarifying the nature of gender-based disparities in respiratory disorders and could usher in more personalized diagnostic and therapeutic approaches.”

The research team enrolled 12 newborns and infants in the study and obtained their nasal wash samples. Six of the infants were born preterm, and six were born full term. The researchers developed a robust gender classification algorithm to generate DNA methylation signals. The machine learning algorithm identified X-linked genes with significant differences in methylation patterns in boys, compared with girls.

As a comparison group, they retrieved pediatric nasal airway epithelial cultures from a study that looked at genomic DNA methylation patterns and gene expression in 36 children with persistent atopic asthma compared with 36 heathy children.

The team went on to classify X-linked genes that had significant gender-based X methylation and those genes whose X methylation was variable.

“These results confirm that the X chromosome contains crucial information about gender-related genetic differences in different airway tissues,” Dr. Nino says. “More detailed knowledge of the genetic basis for gender differences in the respiratory system may help to predict, prevent and treat respiratory disorders that can affect patients over their entire lifetimes.”

MRI finds novel brain defects in Zika-exposed newborns

Sarah Mulkey

“Imaging is constantly helping us make new discoveries with this virus, and in these two cases we found things that had not been previously described,” says Sarah Mulkey, M.D., Ph.D.

Magnetic resonance imaging (MRI) has identified two brain abnormalities never before reported in newborns with prenatal exposure to the Zika virus. Children’s National Health System researchers reported these findings from a study of more than 70 fetuses or newborns with Zika exposure in utero. The study was published in the January 2018 edition of Pediatric Neurology.

The two novel defects – cranial nerve enhancement and cerebral infarction – may join the growing list of neurological findings associated with congenital Zika infection.

“Imaging is constantly helping us make new discoveries with this virus, and in these two cases we found things that had not been previously described,” says Sarah Mulkey, M.D., Ph.D., the study’s lead author and a fetal-neonatal neurologist at Children’s National. Dr. Mulkey works in Children’s Congenital Zika Virus Program, one of the nation’s first comprehensive, dedicated Zika programs.

The research team recommends that postnatal brain MRI be considered in addition to ultrasound for newborns exposed to Zika in utero. “Brain MRI can be performed in the newborn often without sedation and provides an opportunity to look for brain abnormalities we might not catch otherwise – or might not detect until much later,” says Dr. Mulkey.

Birth defects are seen in 6 to 11 percent of pregnancies affected by Zika, and some of the neurological complications in infants are not apparent until well after birth.

Of the two infants in which the new abnormalities were observed, both had normal head size at birth. Neither had smaller-than-normal head size (microcephaly), one of the more severe effects associated with congenital Zika syndrome.

One infant had a normal neurological evaluation at 2 days of age. However, a brain MRI conducted the following day, using gadolinium contrast due to concern of infection, showed enhancement of multiple cranial nerves. “Nerve root enhancement is very rare in a newborn and had not been described with Zika before,” Dr. Mulkey says. “Yet, there was no neurological deficit that we could identify by physical exam.”

The research team acknowledges that the clinical significance of this finding is not yet known.

In the second patient, brain MRI conducted without contrast at 16 days of age revealed a small area consistent with chronic infarction (ischemic stroke) that likely occurred during the third trimester.

“We followed the mother throughout her pregnancy, and both MRI and ultrasound imaging were normal at 28 weeks gestation,” Dr. Mulkey says. “A postnatal ultrasound was also normal, but the postnatal MRI showed a stroke that had occurred at least one month prior to the MRI and after the last fetal study.”

She adds: “This is the first published report of fetal stroke associated with Zika infection, and it may add to our knowledge of what can occur with congenital Zika infection.”

Unlike most congenital infections, Zika virus does not appear to cause viral-induced placental inflammation, which can lead to fetal stroke. So, the authors say they cannot be sure that congenital Zika contributed to the infarct in this case. However, they write, “Given the relatively low incidence of perinatal ischemic infarct and the lack of other maternal- or birth-related risk factors for this patient, Zika infection is considered a possible etiology.”

In both patients, neonatal brain MRI identified subclinical findings that had not previously been described as part of congenital Zika syndrome. As the body of evidence about the Zika virus has grown, the spectrum of associated brain abnormalities has expanded to include considerably more findings than isolated microcephaly.

Data gathered in 2017 from the Centers for Disease Control and Prevention’s Zika pregnancy and infant registry indicates that 25 percent of eligible U.S. infants receive recommended postnatal imaging. Dr. Mulkey said this represents many possible missed opportunities for earlier identification of brain abnormalities.

“Brain MRI should be considered in all newborns exposed to Zika virus in utero, even in the presence of normal birth head circumference, normal cranial ultrasound and normal fetal imaging,” she says. “In both of these patients, the changes we observed were not evident on cranial ultrasound or on fetal MRI and fetal ultrasound.”

In addition to Dr. Mulkey, Children’s co-authors include L. Gilbert Vezina, M.D., Neuroradiology Program director; Dorothy I. Bulas, M.D., chief of Diagnostic Imaging and Radiology; Zarir Khademian, M.D., radiologist; Anna Blask, M.D., radiologist; Youssef A.

Lawrence D'Angelo

Being a young parent while also HIV positive

Lawrence D'Angelo

“We realize that at some point in time, these patients will have to transition their care to an adult setting, and they will confront a different kind of health system,” says Lawrence D’Angelo, M.D., M.P.H. “We want to make sure all of their providers will be able to help them advocate for themselves and for their children.”

By the time the human immunodeficiency virus (HIV) – the virus that causes AIDS – first came to the public consciousness in the 1980s, it was clear that infected pregnant mothers readily pass it to their babies. For those infected babies to eventually have their own children was inconceivable then, says Lawrence J. D’Angelo, M.D., M.P.H., adolescent medicine specialist at Children’s National Health System. Before the advent of antiretroviral therapy, AIDS was universally fatal.

Now, about 22 percent of young adults with HIV have lived with this disease their entire lives. And like many people this age, they’re exploring romantic relationships, sex and – for some – parenthood. This unexpected turn of events, Dr. D’Angelo explains, has left many health care providers unprepared.

“We never expected that these individuals would live to reach early adulthood, so we certainly didn’t expect them to be involved in parenting,” he says. “We have no real knowledge of what to expect from them or how best to support them because we don’t understand what they’re going through.”

To learn more about these young parents living with perinatally acquired HIV (PHIV), Dr. D’Angelo worked with Cynthia Fair, professor of human services studies and public health studies coordinator at Elon University. The two conducted a qualitative assessment of parents with PHIV. After recruiting 17 individuals who fit this description directly from Dr. D’Angelo’s practice, interviewers on the research team sat down with study participants to have a conversation about what it was like to parent while also being HIV positive. They asked standard questions, such as: What do you think makes a good parent? And, describe your relationship with your parents or caregivers. How does this relate, if at all, to your views on parenthood?

The team then transcribed these interviews and fed the text into a qualitative analysis program. With the aid of this software, and their own manual analysis, the researchers found several themes emerge from the conversations.

About 90 percent of the interviews focused on challenges universal to nearly every parent: Worries about a baby taking a bottle or sleeping through the night, struggles with discipline, concerns about money. “For the most part, these are young parents with a chronic illness just trying to be good parents,” says Fair, lead author of the study published Nov. 1, 2017 in AIDS Patient Care and STDs.

However, she adds, HIV inserts an added layer of complexity. Many of the parents said they felt deprived of the opportunity to enjoy lives as long and healthy as their peers. Consequently, having a child carried a sense of pressure to accomplish more in life for their children and to leave a positive legacy. Some worried that their own HIV status would stigmatize their children and that people outside their families would automatically assume their children were HIV positive when they weren’t.

All but one parent in the study had a child who was HIV negative, but even those children require regular testing to make sure they maintain that status. Parents with infants prescribed preventive protocols spoke about the exhaustion of having to deliver prophylactic medicines around the clock. The sole parent in the study with an HIV-positive child was separated from the baby’s father; she talked about the stress of not knowing whether her baby was receiving the necessary medicines to stay healthy when the child wasn’t with her.

These young parents also spoke with interviewers about the role their own pediatric care providers played in helping them make the transition to parenthood. For example, social workers on one study participant’s care team stepped in when she had nowhere to live, finding her an appropriate shelter. Another talked about how her desire to be a good parent was strongly influenced by the care she was given by her medical providers growing up. Many of the study participants had lost one or both parents to HIV or had absentee parents due to incarceration or other causes, says Fair, making their relationships with their medical team one of the few constants they could count on.

That’s why helping care providers develop a deep understanding of the perspectives of PHIV parents is even more important, particularly as these individuals move from pediatric to adult care settings, says Dr. D’Angelo, the study’s senior author and director of the Youth Pride and Burgess Clinics at Children’s National.

“We realize that at some point in time, these patients will have to transition their care to an adult setting, and they will confront a different kind of health system,” he says. “We want to make sure all of their providers will be able to help them advocate for themselves and for their children.”

Millenial Panel at Population Strategies for Childrens Health Summit

Population health and value based care discussed at the Population Strategies for Children’s Health Summit

With sponsorship from Cerner Corporation, Children’s National held the first Population Strategies for Children’s Health (PSCH) event on February 19 – 20, 2018 at The Westin City Center in Washington, D.C. Speakers and attendees gathered from around the country to discuss pediatric population health and the transition to value based care.

PSCH opened with an insightful presentation from Ellen-Marie Whelan Ph.D., CRNP, FAAN, chief population health officer at the CMS Center for Medicaid and CHIP Services. Her presentation, “Medicaid Transformation to Value Based Care,” explored an incentivized health care delivery system reform that will result in better care, smarter spending and healthier people.

Sean Gleeson, M.D., M.B.A., president of Partners for Kids at Nationwide Children’s Hospital, spoke about the mechanics of Partners for Kids and the population health strategies they choose to implement. These strategies require an entire enterprise to be engaged and they must be an intentional component of each healthcare organization. Dr. Gleeson put it simply that population health turns healthcare “right side up” by tying financial incentives to positive value outcomes versus upside down when health organizations make more money when kids are sicker.

A presentation from William Feaster, M.D., M.B.A., chief medical information officer at CHOC Children’s Hospital, and Brian Jacobs, M.D., vice president, chief medical information officer and chief information officer at Children’s National Health System, delved into implementing condition-specific pediatric registries. They highlighted that it’s necessary to integrate registries and workflows into the daily work of clinicians and make them actionable to encourage engagement.

Another highlight of the conference was the millennial panel “The Current and Future State of Health Care from a Consumer’s Perspective.” The panel consisted of Janice Bitetti, a physician and mother of a 10-year-old with Type 1 diabetes; Jonathan Morris, a 15-year-old Type 1 Diabetes patient at Children’s National; and moderator Emily Webber, M.D., FAAP, chief medical information officer at Riley Children’s Hospital. Panel participants shared their take on the current state of Type 1 diabetes care, and the way millennials interact with healthcare. Both Jonathan and Janice agreed that the intensive nature of Type 1 diabetes care puts many families who don’t have the time, resources and initiative that they do in a very difficult place.

Other speakers throughout the two day event explored topics including population health strategies to reduce child health disparities, the role of telehealth in population health, care coordination and coaching to health, and technology in population health.
