Boosting parental resilience in the NICU

newborn kangaroo care

Preliminary findings from an ongoing cross-sectional study presented during the American Academy of Pediatrics 2018 National Conference & Exhibition suggests a strong relationship between resilience and the presence of social support, which may help parents to better contend with psychological distress related to their preterm infant being in the NICU.

Resilience is the remarkable ability of some people to bounce back and overcome stress, trauma and adversity. Being resilient is especially important for parents whose babies are born prematurely – a condition that predisposes these children to numerous health risks both immediately and far into the future and that often triggers a stay in the neonatal intensive care unit (NICU). According to the Centers for Disease Control and Prevention, about 1 in 10 U.S. infants was born preterm in 2016.

Parents of these vulnerable newborns who feel less resilient may experience more symptoms of psychological distress, including depression and anxiety. However, preliminary findings from an ongoing cross-sectional study presented during the American Academy of Pediatrics (AAP) National Conference & Exhibition suggests a strong relationship between resilience and the presence of social support, which may help parents to better contend with psychological distress related to their preterm infant being in the NICU.

“Oftentimes, parenting a child in the NICU can be a time of crisis for families,” says Ololade A. Okito, M.D., FAAP, a Neonatal-Perinatal Medicine Fellow at Children’s National Health System who presented the preliminary study results during the 2018 AAP conference. “Studies have indicated a relationship between higher resilience and a reduction in psychological stress in other groups of people. However, it was unclear whether that finding also applies to parents of infants in the NICU.”

Because parental psychological distress can impact the quality of parent-child interactions, the Children’s research team wants to evaluate the relationship between resilience and psychological distress in these parents and to gauge whether activities that parents themselves direct, like the skin-to-skin contact that accompanies kangaroo care, helps to bolster resiliency.

So far, they have analyzed data from 30 parents of preterm infants in the NICU and used a number of validated instruments to assess parental resilience, depressive symptoms, anxiety, NICU-related stress and perceived social support, including:

The infants were born at a mean gestational age of 29.2 weeks. When their newborns were 2 weeks old:

  • 44 percent of parents (16 of 30) reported higher resilience
  • 37 percent of parents (11 of 30) screened positive for having elevated symptoms of depression and
  • 33 percent of parents had elevated anxiety.

“These early findings appear to support a relationship between low parental resilience scores and higher scores for depression, anxiety and NICU-related stress. These same parents were less likely to participate in kangaroo care and had lower social support. By contrast, parents who had more social support – including  receiving support from family, friends and significant others – had higher resilience scores,” says Lamia Soghier, M.D., FAAP, CHSE, Medical Unit Director of Children’s Neonatal Intensive Care Unit and senior study author.

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. The research team hopes to complete study enrollment in early 2019.

Lyme disease: When will pediatric symptoms resolve?

Deer tick

Over a 13-year period that began in 2004, cases of illness transmitted by ticks, mosquitoes and fleas have more than tripled, the CDC found.

The summer of 2018 was a bad summer for Lyme disease, the tick-borne disease that was first documented in the 1970s in the town of Lyme, Connecticut. While about 30,000 cases of this disease had been reported annually in recent years, studies suggest that the actual number of infections is around 10 times greater.

And according to a study published May 2018 by the Centers for Disease Control and Prevention (CDC), those case numbers may increase over time. Over a 13-year period that began in 2004, cases of illness transmitted by ticks, mosquitoes and fleas have more than tripled, the CDC found.

Lyme disease causes a host of uncomfortable symptoms, ranging from headache and neurological problems, heart problems and eye inflammation in earlier stages, and progressing to joint pain and arthritis in later stages. While it can be treated successfully with appropriate antibiotics, the timeframe for kids’ symptom resolution has been unclear.

A new study by researchers at Children’s National Health System shows that symptoms improve just days or weeks after starting antibiotic therapy for the vast majority of patients, with people whose symptoms had been present a briefer time improving the fastest.

“These findings offer a reassuring timeline for doctors, patients and their families about when patients with Lyme disease can expect to feel better,” says study Senior Author Roberta L. DeBiasi, M.D., MS, Children’s National’s chief of the Division of Pediatric Infectious Diseases and co-director of the Congenital Zika Virus Program. Dr. DeBiasi was recently appointed to serve on a 52-member Tick-Borne Disease Working Group established in 2018 by the Department of Health and Human Services.

Dr. DeBiasi and colleagues collected data retrospectively from the medical records of 78 patients who had been hospitalized at Children’s National for Lyme disease from 2008 to 2015. Each child, who was younger than 18 years old, had documented symptoms and lab tests conclusive for this disease.

Just under one-half had symptoms consistent with early-stage disease, such as:

  • A severe headache
  • Meningitis (inflammation of the membranes covering the brain)
  • Cranial nerve palsy (a nerve dysfunction that affects eye movement and can cause double vision)
  • Multiple erythema migrans rashes (the bulls-eye-shaped rash that’s a hallmark of Lyme disease) and
  • Pseudotumor cerebri (increased pressure inside the skull).

Just over one-half had symptoms consistent with late-stage disease, which mostly consisted of arthritis affecting the knees, along with the hips and elbows in some cases.

In the hospital, each patient was started on an antibiotic that can effectively treat Lyme, including doxycycline, cefotaxime or ceftriaxone, which they continued at home for the prescribed length of the course. The researchers then tracked how quickly the patients’ symptoms resolved.

They report online July 30, 2018, in the Journal of the Pediatric Infectious Diseases Society, that the time to symptom resolution for early stages of disease did not depend on the duration of symptoms prior to starting antibiotics. However, for later stages of disease, patients with longer duration of symptoms prior to starting treatment took longer for their symptoms to resolve.

For patients with early-stage disease, the most common symptom was headache; the median time to symptom resolution was just three days, no matter how long the headache had persisted before treatment started. However, for patients with late-stage Lyme disease, the median time to resolution was 18 days. However, the time depended largely on how long symptoms had persisted before patients began taking antibiotics. For example, patients who had experienced arthritis for less than one week had a shorter time to resolution than those who had arthritis for more than two weeks.

This finding is important, Dr. DeBiasi says, because it suggests that diagnosing Lyme disease earlier – and prescribing the appropriate therapy as soon as possible – can hasten recovery. The vast majority of patients in the study, she adds, eventually experienced full resolution of their symptoms, which should be comforting to families worried about whether their child will ever feel well again.

“We all want what patients and their families want: to feel better as quickly as possible,” Dr. DeBiasi says. “This study gives us valuable information about how soon that will happen given the duration of pediatric patients’ symptoms.”

Dr. DeBiasi and Children’s Psychologist Maureen Monaghan, Ph.D., are leading another Lyme study in collaboration with the National Institutes of Health/National Institute of Allergy and Infectious Diseases to evaluate symptom resolution, quality of life and neurocognitive outcomes in a larger group of pediatric patients with Lyme disease.

In addition to Dr. DeBiasi and Monaghan, Children’s co-authors include Lead Author Mattia E. Chason; Biostatistician Jichuan Wang, Ph.D.; and Yao Cheng.

Making the case for a comprehensive national registry for pediatric CKD

Marva Moxey Mims

“It’s of utmost importance that we develop more sensitive ways to identify children who are at heightened risk for developing CKD.,” says Marva Moxey-Mims, M.D. “A growing body of evidence suggests that this includes children treated in pediatric intensive care units who sustained acute kidney injury, infants born preterm and low birth weight, and obese children.”

Even though chronic kidney disease (CKD) is a global epidemic that imperils cardiovascular health, impairs quality of life and heightens mortality, very little is known about how CKD uniquely impacts children and how kids may be spared from its more devastating effects.

That makes a study published in the November 2018 issue of the American Journal of Kidney Diseases all the more notable because it represents the largest population-based study of CKD prevalence in a nationally representative cohort of adolescents aged 12 to 18, Sun-Young Ahn, M.D., and Marva Moxey-Mims, M.D., of Children’s National Health System, write in a companion editorial published online Oct. 18, 2018.

In their invited commentary, “Chronic kidney disease in children: the importance of a national epidemiological study,” Drs. Ahn and Moxey-Mims point out that pediatric CKD can contribute to growth failure, developmental and neurocognitive defects and impaired cardiovascular health.

“Children who require renal-replacement therapy suffer mortality rates that are 30 times higher than children who don’t have end-stage renal disease,” adds Dr. Moxey-Mims, chief of the Division of Nephrology at Children’s National. “It’s of utmost importance that we develop more sensitive ways to identify children who are at heightened risk for developing CKD. A growing body of evidence suggests that this includes children treated in pediatric intensive care units who sustained acute kidney injury, infants born preterm and low birth weight, and obese children.”

At its early stages, pediatric CKD usually has few symptoms, and clinicians around the world lack validated biomarkers to spot the disease early, before it may become irreversible.

While national mass urine screening programs in Japan, Taiwan and Korea have demonstrated success in early detection of CKD, which enabled successful interventions, such an approach is not cost-effective for the U.S., Drs. Ahn and Moxey-Mims write.

According to the Centers for Disease Control and Prevention, 1 in 10 U.S. infants in 2016 was born preterm, prior to 37 weeks gestation. Because of that trend, the commentators advocate for “a concerted national effort” to track preterm and low birth weight newborns. (These infants are presumed to have lower nephron endowment, which increases their risk for developing end-stage kidney disease.)

“We need a comprehensive, national registry just for pediatric CKD, a database that represents the entire U.S. population that we could query to glean new insights about what improves kids’ lifespan and quality of life. With a large database of anonymized pediatric patient records we could, for example, assess the effectiveness of specific therapeutic interventions, such as angiotensin-converting enzyme inhibitors, in improving care and slowing CKD progression in kids,” Dr. Moxey-Mims adds.

Maureen E Lyon

Maureen E. Lyon, Ph.D., ABPP, lauded for outstanding excellence in patient-centered advance care planning

Maureen E Lyon

Maureen E. Lyon, Ph.D., a principal investigator at Children’s Center for Translational Science, will be honored with a “Recognition Award for Excellence and Innovation in Research” by Respecting Choices for outstanding excellence in patient-centered advance care planning and shared decision-making.

Respecting Choices will present the award on Oct. 26, 2018, during its “National Share the Experience Conference” in Bloomington, Minnesota.

Lyon’s expertise is in advance care planning and shared decision-making for children and adolescents with life-threatening illnesses and their families, a field that has transformed in recent decades in order to pave better paths forward for difficult but necessary conversations.

“It came from my clinical experience,” Lyon says. “In the early days of the human immunodeficiency virus (HIV) epidemic in the U.S., everything, absolutely everything, was done to keep the kids alive in the hopes that some new drug would come around the corner, and we could bring them back from the brink. I remember one of the young boys saying to his case manager that he didn’t want all of these interventions. But he hadn’t told his family.”

That young man’s eye-opening comments – and learning that Children’s National Health System had a policy that teenagers were to be included in conversations about their own advance care planning – inspired Lyon to conduct a series of surveys involving adolescents, families and clinicians.

“I remember sitting down with friends and saying ‘There must be a better way to do this. Everyone is afraid to broach the subject,’ ” Lyon recalls. So, she conducted surveys of all healthy kids coming through Children’s adolescent clinic and kids diagnosed with HIV, cancer and sickle cell disease.

“It turned out the kids did want to talk about it. That was the first thing. Families told us they wanted help breaking the ice. Physicians felt it wasn’t their role – many doctors felt their role was to save people – or, they didn’t have the training,” she says.

Through a series of focus groups with youths living with HIV, families and community members, Lyon adapted the adult-centric Respecting Choices model to create a three-session intervention to better meet the advance care planning needs of youths and adolescents living with HIV.

Lyon’s recent work includes a single-blinded, randomized study published Oct. 19, 2018, in Pediatrics that finds the more families understand the end-of-life treatment preferences expressed by adolescents living with HIV, the less likely these youth are to suffer HIV-related symptoms, compared with youths whose families do not understand their end-of-life care goals.

She also has adapted the Respecting Choices intervention to facilitate its use with children diagnosed with cancer. More recently, she has adapted the model for use by parents of children with rare diseases who cannot communicate on their own.

“For the other life-threatening health conditions, we worked to support adolescents in expressing their advance care planning choices in their own voices. With rare diseases, we’re shifting gears,” she adds.

Published research indicates a sizable proportion of pediatric patients who die in hospitals now have confirmed or suspected rare diseases, she says. During a pilot involving seven families, many parents multitasked during the conversations, taking pauses to attend to various alarms as they sounded, to complete regular feedings and to contend with their child’s petit mal seizures.

“The level of burden of taking care of these children with terminal illnesses was pretty overwhelming,” she says. “Still, families were not too burdened to participate in advance care planning, but first wanted to identify their priority palliative care needs and to develop a support plan to meet those needs. We also had more fathers involved.”

Shayna Coburn, Ph.D., assistant professor and psychologist at Children’s National Health System, has been awarded an American Psychological Association (APA) Achievement Award for Early Career Psychologists.

APA’s Committee on Early Career Psychologists announced the award for early career members who work in all areas of psychology (education, practice, public interest and science) to attend the APA Annual Convention August 2018 in San Francisco.

“At this early stage in my career, the recognition of my achievements thus far is highly valuable as I expand my body of work and strive to advance my career,” Coburn says.

The awards program was designed to reduce barriers to early career members’ attending APA conventions and to support their ability to make meaningful connections and engage in professional development. As a recipient of the award, Coburn received reimbursement up to $400 for convention-related expenses that could cover travel, lodging, meals and/or convention registration fees.

Throughout her career, Coburn has been passionate about clinical and research excellence as well as advocacy. In her current position in the celiac disease program, she has been involved with establishing a new psychosocial health program that combines multidisciplinary clinical service, research and community outreach.

During a previous APA convention, Coburn was able to attend as an exhibitor to promote a free continuing education program. This year was the first time she was featured as a presenter, speaking about celiac disease and psychosocial challenges associated with the disease.

Coburn presented data from Children’s National celiac disease multidisciplinary clinic to report the incidence rates of symptoms that patients experience such as anxiety, depression and stress from a gluten-free diet.

“The most important aspect of the award was having the largest organization of psychologists recognize that during the early stages of my career, I have been involved in work that is meaningful to the community,” Coburn says. “It’s always helpful to have extra support to attend a conference that is across the country from my home in Maryland,” she adds.

The leader and collaborator in a range of scientific, clinical and community-based activities thanks the award for being invaluable in facilitating her attending the conference and being able to participate in career-building and networking opportunities that will help enable her to build professional relationships nationwide.

Stephen Teach does an asthma exam

Stephen Teach does an asthma exam

Stephen J. Teach, M.D., M.P.H., has been named the inaugural Wendy Goldberg Professor in Translational Research in Child Health and Community Partnerships. This professorship comes with an endowed chair at Children’s National Health System.

The prestigious honor is given for the duration of Dr. Teach’s (and future chair holders’) employment at Children’s National. The award’s namesake, Wendy Goldberg, and her husband, Fred T. Goldberg Jr., are among the brightest stars in the constellation of Children’s National supporters, says Dr. Teach, Associate Dean for Pediatric Academic Affairs and Chair of the Department of Pediatrics at The George Washington University School of Medicine & Health Sciences.

In addition to serving on many Children’s boards, in the mid-2000s the Goldbergs made a $250,000 gift that benefited Improving Pediatric Asthma Care in the District of Columbia (IMPACT DC), Dr. Teach’s award-winning program to improve clinical care, empower patients and families, and conduct new research to improve patients’ outcomes.

“In recognition of the anchor aims of Children’s new strategic plan, the Goldbergs wanted this new gift to focus on the intersection of community health and research,” Dr. Teach says. “Thanks to their generosity, my team will work with community partners to use data to drive improvements in population health.”

With the dedicated funding Dr. Teach was able to hire a new staffer, Caitlin Munoz, to help mine electronic health records to create disease-specific registries that include 15,000 children and adolescents – the lion’s share of kids younger than 17 who live in Washington and have asthma.

“For the first time, we will be able to describe in granular detail the near-universe of local children who have this chronic respiratory disease,” he says. “We will be able to describe many of the most clinically meaningful aspects of nearly every child with asthma who lives in D.C., including mean age, gender, ethnicity and mean number visits to the emergency department.”

Such a richly textured database will help identify children who should be prescribed daily controller medications to help them avoid missing school days due to asthma exacerbations, he says. The next pediatric chronic disease they will track via registry will be pediatric obesity via elevated body mass index.

“That, in and of itself, is insightful data. But the enduring impact of this applied research is it will inform our continuous quality-improvement efforts,” he adds.

By querying the registries the team will be able to tell, for example, how Children’s primary care centers rank comparatively by asking such questions as which percentage of kids with asthma actually take the medicines they had been prescribed the year prior.

“Increasingly, clinical research falls into one of two buckets. You can either do better things: That’s discovering new drugs or processes, like our ongoing clinical trial to desensitize kids to asthma allergens. Or, you can do things better. We often know what to do already. We know that guideline-based asthma care works well. We don’t need to prove that again. We just need to do things better by getting this care to the kids who need it. That’s where this line of research/quality improvement comes in: It’s getting people to do things better.”

Phage therapy draws renewed interest to combat drug-resistant microbes

bacteriophage

In the face of growing antibiotic resistance and few antibiotics in the development pipeline, phages are drawing renewed research interest as a potential silver bullet.

The married professors were spending their Thanksgiving holiday in Egypt when the husband, Thomas L. Patterson, Ph.D., got very sick very quickly, experiencing fever, nausea and a racing heartbeat. By the time Patterson was accurately diagnosed with a highly multi-drug resistant bacterial infection, he was near death. His wife, Steffanie Strathdee, Ph.D., promised to “leave no stone unturned.’”

What happened next is the ultimate infectious disease feel good story: Strathdee, part of an All-Star team of infectious disease experts and epidemiologists, concocted a cocktail of viruses that killed the superbug and saved Patterson’s life.

“He was going to die,” says Roberta L. DeBiasi, M.D., MS, chief of the Division of Pediatric Infectious Diseases at Children’s National Health System. “Because of her epidemiology background – and because she loves him – Patterson became the first patient successfully treated with bacteriophages.”

Dr. DeBiasi explains that all viruses take over cells and use their machinery for their own purposes. In order to escape, viruses blow up the cell. Bacteriophages are viruses that target bacteria, taking over their machinery and ultimately killing the bacterial host.

“Infection is a race between the body’s immune response and the bacteria replicating themselves,” she adds. “Bacteria have to continually replicate. If you knock out 90 percent of them with phage therapy, that gives the immune system a fighting chance to win the race.”

She was so inspired by the team’s ingenuity that DeBiasi, program vice-chair, invited them to recount the story during IDWeek2018, held Oct. 3 to Oct. 7, 2018, in San Francisco. During the closing plenary, Patterson, a professor of psychiatry, and Strathdee, associate dean of Global Health Sciences, will be joined by Robert T. “Chip” Schooley, M.D., (all of University of California, San Diego), to discuss the clinical aspects and efficacy of phage therapy.

About 50 years ago, the U.S. military had investigated leveraging phages but ultimately placed that research portfolio on the back burner. Now, in the face of growing antibiotic resistance and few experimental antibiotics in the development pipeline, phages are drawing renewed research interest as a potential silver bullet.

“The technology has been around for 50 years. We’re going back to old things because we’re so desperate,” Dr. DeBiasi adds.

The tricky thing with phages is that each bacterium needs its own tailored phage therapy.

Children’s National is working with Adaptive Phage Therapeutics, a company based in Gaithersburg, Maryland, that developed the phage used to save Patterson, in order to help build out that library of phages, each ready to be directed to do battle against a specific pathogen.

“We have been consultants to them to think about what would be a good clinical trial, particularly in a pediatric population,” Dr. DeBiasi says.

Children’s National has been collecting and sending isolates from patients with neurogenic bladder who experience urinary tract infections to shore up the phage library in anticipation of a clinical trial. The work builds on Children’s experience as the first center to use phage therapy in a pediatric patient, a 2-year-old who had multidrug-resistant Pseudomonas aeruginosa infection complicated by bacteremia/sepsis.

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.”

Modified glucocorticoid stabilizes dysferlin-deficient muscle cell membrane in experimental models

Sen Chandra Sreetama and Jyoti K Jaiswal

Limb girdle muscular dystrophy type 2B (LGMD2B) – a disease so rare that researchers aren’t even sure how many people it affects – is characterized by chronic muscle inflammation and progressively weakened muscles in the pelvis and shoulder girdle. It can affect able-bodied people during their childbearing years and makes it difficult to tiptoe, walk, run or rise unaided from a squat. Ultimately, many with the muscle-wasting condition require wheelchair assistance. There is no therapy approved by the Food and Drug Administration for this condition.

In a head-to-head trial between the conventional glucocorticoid, prednisolone, and a modified glucocorticoid, vamorolone, in experimental models of LGMD2B, vamorolone improved dysferlin-deficient muscle cell membrane stability and repair. This correlated with increased muscle strength and decreased muscle degeneration, according to a Children’s-led study published online Aug. 27, 2018, in Molecular Therapy. By contrast, prednisolone worsened muscle weakness, impaired muscle repair and increased myofiber atrophy.

“These two steroids differ by only two chemical groups,” says Jyoti K. Jaiswal, MSC, Ph.D., a principal investigator at Children’s National Health System and senior study author. “One made muscle repair better. The other made muscle repair worse or about the same as untreated experimental models. This matches experience in the clinic as patients with LGMD2B experienced increased muscle weakness after being prescribed conventional glucocorticoids, such as prednisolone.”

Healthy muscle cells rely on the protein dysferlin to properly repair the sarcolemmal membrane, a cell membrane specialized for muscle cells that serves a vital role in ensuring that muscle fibers are strong enough and have the necessary resources to contract. Mutations in the DYSF gene that produces this essential protein causes LGMD2B.

Jaiswal likens the plasma membrane to a balloon that sits atop the myofiber, a long cell that when healthy can flex and contract. If, in the process of myofiber contraction, the plasma membrane experiences anything out of sync or overly stressful, it develops a tear that needs to be quickly sealed. An intact balloon keeps air inside; tear it, and air escapes. When the plasma membrane tears, calcium from the outside leaks in, causing the muscle cell to collapse into a ball and die. The body contends with the dead cell by breaking it up into fragments and sending in inflammatory cells to clear the debris.

Lack of dysferlin is associated with increased lipid mobility in the LGMD2B cell membrane

Lack of dysferlin is associated with increased lipid mobility in the limb girdle muscular dystrophy type 2B (LGMD2B) cell membrane, which is further increased by injury and prednisolone treatment, causing failure of these cells to undergo repair. By contrast, vamorolone treatment stabilizes the LGMD2B muscle cell membrane to near healthy cell level, enabling repair of injured cells.

The study team got the idea for the current research project during a previous study of the experimental treatment vamorolone for a different type of muscular dystrophy. “In Duchenne muscular dystrophy (DMD), treatment with vamorolone not only reduced inflammation, but the membranes of muscle fibers were stabilized. That was the team’s ah-hah moment,” he says.

Three different doses of vamorolone were tested on cells derived from patients with LGMD2B with higher cell membrane repair efficacy seen with rising treatment dose. The dysferlinopathic experimental models were treated for three months with daily doses of cherry syrup laced with either 30 mg/kg of vamorolone or prednisolone or cherry syrup alone as the placebo arm.

“Right now there are zero treatments,” he says. People with LGMD2B turn to rehabilitative therapies and movement aids to cope with loss of mobility. Doctors are cautioned not to prescribe steroids. Jaiswal says many patients with LGMD2B grew up doing strenuous exercise, former athletes whose first indication of a problem was muscle cramping and pain. How this progresses to muscle weakness and loss is an area of active research in Jaiswal’s lab. “While additional research is needed, our findings here suggest that modified steroids such as vamorlone may be an option for some patients,” Jaiswal says.

“There is a nuance here: In addition to genomic effects, steroids also have physical effects on the cell membrane which may make some of the approved steroids ‘good’ steroids for dysferlinopathy that could selectively be used for this disease,” adds Sen Chandra Sreetama, lead study author.  Further research could indicate whether vamorolone, which is in Phase II human clinical trials for DMD, or any off-the-shelf drug could slow decline in muscle function for patients with LGMD2B.

Understanding individual and collective mechanisms behind cell membrane repair

Tissue repair signaling illustration

Signals released during plasma membrane repair initiate tissue repair: Extracellular vesicle signaling, an intracellular calcium increase that initiates plasma membrane repair in injured cells and an increase in cytosolic calcium that stimulates release of ATP by vesicle exocytosis or through plasma membrane channels.

What’s known

All cells are surrounded by a cell membrane: a double layer of lipids with embedded proteins that separates the inside of the cell from the outside environment. At only 10 nanometers in thickness, this layer is quite fragile. Any breach can be fatal for a cell, causing chemical imbalances by exposing its interior to the extracellular milieu. Consequently, cells have evolved a set of responses to rapidly restore the integrity of the cell membrane in the event of a rupture, coordinating actions spurred by both immediate and longer-term signals. Research is providing a growing understanding of these repair mechanisms, which could go awry in degenerative diseases.

What’s new

Adam Horn, Ph.D., a postdoctoral fellow, and Jyoti K. Jaiswal, Ph.D., a principal investigator at Children’s Center for Neuroscience Research and the Center for Genetic Medicine Research, recently co-authored a literature review article summarizing these cell membrane repair mechanisms and the signals that trigger them. They delve into a variety of resourceful ways that cells fix tears or holes in this membrane, including one akin to blood clotting that stuffs a tear with proteins, organelles or vesicles; another in which the proteins that give a cell structure (the cytoskeleton) disassemble, relaxing tension that helps pull the damaged membrane together; or one in which the damaged portion in the membrane is shed. These repairs are driven by signals that largely rely on a large calcium influx into the cellular fluid, which spurs into action a variety of repair-related proteins. Better understanding each element could help researchers develop new and better ways to treat degenerative diseases in which cells inadequately repair damage.

Questions for future research

Q: How do the different types of signals coordinate individual and collective mechanisms of cell membrane repair?

Q: How is cell membrane repair coordinated among populations of cells at the tissue level?

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.”

Emergency Department Check in

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.”

In addition to Dr. Goyal, Children’s study co-authors include Lead Author, Amanda Jichlinski, M.D.; and co-authors, Gia Badolato, M.P.H., and William Pastor, M.A., M.P.H.

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, Staphyloccoccus 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.”

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.

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.”

The 12th annual rankings recognize the top 50 pediatric facilities across the U.S. in 10 pediatric specialties: cancer, cardiology and heart surgery, diabetes and endocrinology, gastroenterology and gastrointestinal surgery, neonatology, nephrology, neurology and neurosurgery, orthopedics, pulmonology and urology.

The Best Children’s Hospitals Honor Roll recognizes the 10 hospitals that received the most points overall.

This year’s rankings will be published in the U.S. News & World Report’s “Best Hospitals 2019” guidebook, available for purchase in late September.

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.”
