Studying the impact of later school start times

general school supplies

Teens have a biological preference to fall asleep later than younger children and adults, and wake up later, due to a delayed release of hormones that promote sleep. This timing coincides with puberty and makes it harder for middle and high school students to fall asleep early – regardless of 5 a.m. alarms and 7:17 a.m. school start times.

After studying this trend among nearly 1,000 seventh and eighth-grade students in 11 middle schools within a Mid-Atlantic school district, Daniel Lewin, Ph.D., a sleep medicine specialist, pediatric psychologist and associate director of the sleep medicine program at Children’s National Health System, coauthored and published research entitled “Later Start, Longer Sleep: Implications of Middle School Start Times” in the Journal of School Health, which outlines the benefits of delaying school start times.

The research team divided students into two groups: Close to 650 students attended eight late-starting middle schools, where school started at 8 a.m., while nearly 350 students attended early-starting middle schools, where school started at 7:23 a.m.

Students starting school 37 minutes later, despite going to bed 15 minutes later than peers attending an earlier-starting school, got 17 minutes more sleep each night and were more likely to report feeling wide awake during class. The researchers predicted this later-starting school model would translate to students getting an extra 75 minutes of sleep a week – roughly 51 hours of extra sleep each school year. These researchers find that every two minutes in delayed school start times results in one minute of additional sleep each night for children and teens.

Sleep Chart

Middle and high school students should get 8.5 to 10.5 hours of sleep each night, ideally between 9 p.m. and 8:30 a.m. for 12- to 15-year-olds and 10:30 p.m. and 9 a.m. for 16- to 18-year-olds.

The American Academy of Pediatrics (AAP) published similar research in their journal, Pediatrics, about the benefits of letting teens catch up on sleep, citing a reduced risk of students being overweight, getting into car accidents or suffering from depression as well as a greater likelihood of having better grades, higher test scores and a better quality of life. AAP recommends schools start at 8:30 a.m. or later to allow students to get 8.5 to 9.5 hours of sleep each night and issued a statement in 2014, entitled “School Start Times for Adolescents.”

Dr. Lewin continues to track these benefits and works with schools to implement the changes. He recently wrote an editorial, entitled “All the Clocks Are Ticking: Sleep Health and Metabolism,” for the Journal of Adolescent Health about the correlation between improved sleep health, mental and physical health and academic performance, explaining how circadian clocks, present on a cellular level, influence behavior and metabolism.

While pushing school start times back requires an immediate investment of rearranging travel routes, bell schedules and after-school activities, several school districts near Washington, D.C., from Virginia Beach to Fairfax County, are adopting this public health model.

An economic analysis conducted by the RAND Corporation finds that after two years, the benefits of reorganizing school start times outweigh the costs.

#thisisourlane: Pediatricians call for safer firearm storage, enhanced research funding

Lenore Jarvis at #thisisourlane meeting

The 2-year-old scampered unexpectedly into a room, startling a family member. Thinking the toddler was an intruder, the family member fired, hitting the child in the chest.

In the emergency department at Children’s National Health System, Lenore Jarvis, M.D. MEd, FAAP, emergency medicine specialist, and colleagues tried to save the boy’s life, inserting tubes, transfusing blood and attempting to restart his dying heart via CPR. The Children’s team was unsuccessful and emerged covered in the blood of a boy whose death was heartbreaking and preventable.

“Firearm violence is a leading cause of childhood traumatic death and injury,” Dr. Jarvis told attendees of a recent congressional news conference intended to prod the incoming Congress to take more concrete action to prevent firearm violence. She provided snapshots of some of the countless lives of local youths cut short by firearms, including an 8-year-old girl killed on a playground in a drive-by shooting, a 13-year-old young man murdered during a fight, a 15-year-old young woman who committed suicide and an entire family who died from firearm injuries.

“I wish it were not so. But these stories are endless. In our emergency department, the effects of gun violence are frequent, life-altering and personal,” Dr. Jarvis said.

The #ThisISOurLane press conference, convened by U.S. Rep. Robin Kelly, (D-Illinois), included haunting stories by clinicians from across the nation about the devastating impact of firearm injuries on children and youth. According to a retrospective, cross-sectional study led by Children’s researchers, younger children are more likely to be shot by accident, and odds are higher that older youths are victims of an assault involving a firearm.

“Gun violence is a public health crisis and should be addressed as such. We need to reduce the numbers of suicides, homicides and accidental gun deaths in children,” added Dr. Jarvis, who also is president-elect of the District of Columbia Chapter of the American Academy of Pediatrics.

During the news conference, U.S. Rep. Frank Pallone Jr., (D-New Jersey), vowed that the House Energy and Commerce Committee he chairs this session will move forward languishing bills, including funding the Centers for Disease Control Prevention to conduct firearms violence research.

PAC1R mutation may be linked to severity of social deficits in autism

DNA moleucle

A mutation of the gene PAC1R may be linked to the severity of social deficits experienced by kids with autism spectrum disorder (ASD), finds a study from a multi-institutional research team led by Children’s National faculty. If the pilot findings are corroborated in larger, multi-center studies, the research published online Dec. 17, 2018, in Autism Research represents the first step toward identifying a potential novel biomarker to guide interventions and better predict outcomes for children with autism.

As many as 1 in 40 children are affected by ASD. Symptoms of the disorder – such as not making eye contact, not responding to one’s name when called, an inability to follow a conversation of more than one speaker or incessantly repeating certain words or phrases – usually crop up by the time a child turns 3.

The developmental disorder is believed to be linked, in part, to disrupted circuitry within the amygdala, a brain structure integral for processing social-emotional information. This study reveals that PAC1R is expressed during key periods of brain development when the amygdala – an almond-shaped cluster of neurons – develops and matures. A properly functioning amygdala, along with brain structures like the prefrontal cortex and cerebellum, are crucial to neurotypical social-emotional processing.

“Our study suggests that an individual with autism who is carrying a mutation in PAC1R may have a greater chance of more severe social problems and disrupted functional brain connectivity with the amygdala,” says Joshua G. Corbin, Ph.D., interim director of the Center for Neuroscience Research at Children’s National Health System and the study’s co-senior author. “Our study is one important step along the pathway to developing new biomarkers for autism spectrum disorder and, hopefully, predicting patients’ outcomes.”

The research team’s insights came through investigating multiple lines of evidence:

  • They looked at gene expression in the brains of an experimental model at days 13.5 and 18.5 of fetal development and day 7 of life, dates that correspond with early, mid and late amygdala development. They confirmed that Pac1r is expressed in the experimental model at a critical time frame for brain development that coincides with the timing for altered brain trajectories with ASD.
  • They looked at gene expression in the human brain by mining publicly available genome-wide transcriptome data, plotting median PAC1R expression values for key brain regions. They found high levels of PAC1R expression at multiple ages with higher PAC1R expression in male brains during the fetal period and higher PAC1R expression in female brains during childhood and early adulthood.
  • One hundred twenty-nine patients with ASD aged 6 to 14 were recruited for behavioral assessment. Of the 48 patients who also participated in neuroimaging, 20 were able to stay awake for five minutes without too much movement as the resting state functional magnetic resonance images were captured. Children who were carriers of the high-risk genotype had higher resting-state connectivity between the amygdala and right posterior temporal gyrus. Connectivity alterations in a region of the brain involved in processing visual motion may influence how kids with ASD perceive socially meaningful information, the authors write.
  • Each child also submitted a saliva sample for DNA genotyping. Previously published research finds that a G to C single nucleotide polymorphism, a single swap in the nucleotides that make up DNA, in PAC1R is associated with higher risk for post traumatic stress disorder in girls. In this behavioral assessment, the research team found children with autism who carried the homozygous CC genotype had higher scores as measured through a validated tool, meaning they had greater social deficits than kids with the heterozygous genotype.

All told, the project is the fruit of six years of painstaking research and data collection, say the researchers. That includes banking patients’ saliva samples collected during clinical visits for future retrospective analyses to determine which genetic mutations were correlated with behavioral and functional brain deficits, Corbin adds.

“Lauren Kenworthy, who directs our Center for Autism Spectrum Disorders, and I have been talking over the years about how we could bring our programs together. We homed in on this project to look at about a dozen genes to assess correlations and brought in experts from genetics and genomics at Children’s National to sequence genes of interest,” he adds. “Linking the bench to bedside is especially difficult in neuroscience. It takes a huge amount of effort and dozens of discussions, and it’s very rare. It’s an exemplar of what we strive for.”

In addition to Corbin, study co-authors include Lead Author Meredith Goodrich and Maria Jesus Herrero, post-doctoral fellow, Children’s Center for Neuroscience Research; Anna Chelsea Armour and co-Senior Author Lauren Kenworthy, Ph.D., Children’s Center for Autism Spectrum Disorders; Karuna Panchapakesan, Joseph Devaney and Susan Knoblach, Ph.D., Children’s Center for Genetic Medicine Research; Xiaozhen You and Chandan J.

The science behind optimal sleep health

smiling baby sleeping

Children younger than age 2 need at least 12 hours of sleep each day.

As families and parents renew their interest in health in the new year, pediatricians can take advantage of this momentum by talking about one area absent from common New Year’s resolutions lists: getting enough sleep.

Like diet, exercise and activities that keep your brain sharp, such as reading or learning a new language, healthful sleep patterns play a vital role in supporting physical health and cognitive performance – especially for children and teens.

Here are a few tips parents and pediatricians can use, based on research published by Daniel Lewin, Ph.D., a pediatric psychologist and sleep medicine specialist at Children’s National Health System.

Understand how much sleep each child needs.

The typical range of recommended sleep, such as eight to 10 hours each night, varies for each child. A 16-year-old may do well with 8.5 hours of sleep, while a 6-year-old may need 13 hours of sleep to stay alert. Their body is still rapidly developing. The timing of sleep matters, too, due to a child’s natural circadian rhythm. A chart below details sleep recommendations based on age.

Sleep Chart

Turn a child’s bedroom into a healthful sleep chamber.

Encouraging children to fall asleep by 7 or 9 p.m. may require planning – outside of maintaining regular sleep schedules. To start, make it easy to promote sound sleep by eliminating distractions, including clocks and electronic devices, which might sit next to a child’s bed and distract him or her from getting a good night’s sleep.

Reserve a designated area for homework and study hours outside of the bedroom, which helps reinforce that the bed is a place for sleep and rest. Avoid doing any complicated routines or activities that might cause excitement right before bed, such as assembling a new toy or playing a high-stakes game.

Follow the same rules for conversations: Don’t have talks that might evoke excitement, like the next Disneyworld vacation, or stress, such as bringing the next day’s spelling test up right before bed. By creating a calm zone, you’ll avoid energizing the biological ‘burst zone,’ a rush of energy that occurs in short bursts before one prepares to rest for the night. Keep conversations and routines simple and soothing. Reading, stretching or practicing mindfulness and yoga are complementary activities children can practice at least 15 minutes before bedtime.

Schedule activities about circadian rhythms.

Understanding when a child sleeps best is just as important as understanding how much sleep is essential to support optimal health. A student in high school is biologically wired to stay up past 9 p.m. due to a later release of hormones that promote sleep. This is one reason some school systems are experimenting with later middle and high school start times, which, according to a review in the Journal of School Health, increases a student’s chance of feeling ‘wide awake’ and alert in the classroom.

If you have control of your student’s schedule, plan around it. For instance, schedule activities for a 17-year-old in the late morning, if possible, while allowing time in the afternoon for a young child to take a nap.

These starter tips serve as ways to strengthen sleep quality. Learn more about Dr. Lewin’s research at PubMed, view a few of his blogs for parents at U.S. News & World Report and learn about the link between sleep and health at the National Institutes of Health. If you experience recurring problems, such as sleep apnea, insomnia, sleep walking, ongoing sleep disruptions or excessive daytime sleepiness, connect with a health care provider.

PICU room

How to help bereaved families

PICU room

To help clinicians provide better care to families after children die, Tessie W. October, M.D., MPH, and colleagues recently published an article on this topic in a special supplement to Pediatric Critical Care Medicine on death and dying.

Death and dying are always difficult topics to discuss at hospitals. They’re especially hard conversations when they occur within pediatric intensive care units (PICUs), says Tessie W. October, M.D., MPH, a critical care specialist at Children’s National.

“It’s almost easier to pretend that children don’t die in the ICU. But they do,” Dr. October says.

Tragically, some children do die in ICUs. However, even when pediatric patients die, Dr. October adds, the pediatric care team’s relationship with the bereaved family continues. Knowing how to help vulnerable families during these trying times and ensuring they have needed resources can be critical to lessening the health and social consequences of grief. To help clinicians provide better care to families after children die, Dr. October and colleagues recently published an article on this topic in a special supplement to Pediatric Critical Care Medicine on death and dying.

The multi-institutional research team performed a narrative literature review for this budding field. They pored through more than 75 papers to better understand the health outcomes of parents whose child died within a PICU and the different ways that hospitals help families cope with these tragedies.

The researchers found a range of detrimental health outcomes, from a significantly increased risk of parental death in the aftermath of a child’s death to higher rates of myocardial infarction, cancer and multiple sclerosis. Bereaved parents used more health care resources themselves, took more sick days and had more sleep problems than parents who weren’t bereaved.

Likewise, parents whose child died were at a high risk of experiencing mental health conditions including complicated grief, anxiety, depression and posttraumatic stress disorder. Divorce was eight times higher among bereaved parents compared with the general population, and financial crises were common after voluntary or involuntary unemployment.

Knowing which risks parents could face can help the care team respond better if a child dies, Dr. October explains. Their review highlighted simple ways to support families in the immediate aftermath of a child’s death and beyond, such as:

  • Giving parents the opportunity to spend time alone with the child’s body
  • Allowing friends, family and others to visit at the parents’ discretion and
  • Providing easy access to professional support, such as chaplains, social workers and grief coordinators.

Even simple acts such as closing doors and blinds to provide privacy can be helpful, Dr. October says.

An ongoing relationship with health care providers is also important for helping parents grieve, she adds. Children’s National is among hospitals across the country to set up meetings for parents and other family members within weeks of a child’s death. This gives parents a chance to ask questions about what happened in the confusing blur of the PICU and to gather resources for themselves and surviving siblings. Children’s National also provides ongoing support through periodic calls, sending sympathy cards, attending funeral services and in a special annual memorial during which surviving family members release butterflies.

“Our role doesn’t end when a child dies,” Dr. October says. “To help parents through bereavement, we need to maintain that strong connection.”

Another way to help bereaved families is to make sure they have adequate information, she adds, particularly about the confusing subject of brain death. In a different study recently published in Chest Journal, Dr. October and Children’s colleagues sought to understand which information the public typically accesses about this topic.

The team searched Google and YouTube using “brain dead” and “brain death” as search terms. They evaluated the top 10 results on both sites, assessing the accuracy of information using 2010 guidelines released by the American Academy of Neurology. They also assessed the reading level of websites and evaluated comments about the YouTube videos for content accuracy and tone.

They found that there was inaccurate information on four of the 10 websites, six of the 10 videos and within 80 percent of the YouTube comments. Most of these inaccuracies dealt with using terms like brain death, coma and persistent vegetative state interchangeably. “These conditions are very different and affect how we treat patients,” Dr. October says.

The average reading level of the websites was 12th grade, far too sophisticated for much of the public to comprehend, she adds. And the majority of comments on the YouTube videos were negative, often disparaging clinicians and deriding organ donation.

“It’s really important for providers to recognize that this is an emotionally laden topic, and a lot of times, families come to us with information that’s not always true,” she says. “That’s why it’s especially important for the field to respond with empathy and care.”

In addition to Dr. October, co-authors of the Pediatric Critical Care Medicine study include Karen Dryden-Palmer, R.N., MSN, Ph.D., The Hospital for Sick Children; Beverley Copnell, Ph.D., BAppSc, R.N., Monash University; and Senior Author Kathleen L. Meert, M.D., FCCM, Children’s Hospital of Michigan. Dr. October’s co-authors for the Chest Journal article include Lead Author, Amy H. Jones, M.D., and co-author Zoelle B. Dizon, BA, both of Children’s National.

How does diet during pregnancy impact allergies in offspring?

pregnant woman holding eggs

A small percentage of women said they consumed fewer allergens during pregnancy to stave off food allergies in their newborns, according to preliminary research Karen Robbins, M.D., presented during the American College of Asthma Allergy and Immunology 2018 Annual Scientific Meeting.

Pregnant women routinely swear off alcohol and tobacco to boost their chances of having a healthy baby. What about common food allergens like nuts and milk?

There are scant data that describe how often pregnant women deliberately stop eating a specific food item in order to prevent future food allergies in their newborns. As a first step toward addressing this data gap, a research team led by Karen Robbins, M.D., an allergist at Children’s National Health System, pored through a longitudinal study conducted by the Food and Drug Administration (FDA) and the Centers for Disease Control and Prevention.

About 4,900 pregnant women completed the Infant Feeding Practices Study II prenatal questionnaire from May 2005 to June 2007. The study tracked 2,000 pregnant women from the third trimester of pregnancy and their infants through the first year of life. A small percentage of women said they had consumed fewer allergens during pregnancy to stave off food allergies in their newborns, according to a poster Dr. Robbins presented during the American College of Asthma Allergy and Immunology 2018 Annual Scientific Meeting. While their numbers were small, most of these women reported giving up major allergens like nuts, milk or eggs during pregnancy, including:

  • 144 (2.9 percent) reported restricting their diet in some way to prevent future food allergies in their offspring
  • 84 women (1.7 percent) ate fewer nuts
  • 15 women (.3 percent) ate fewer eggs and
  • 2 women (.04 percent) ate/drank consumed less dairy/milk.

“At the time the survey was conducted, few pregnant women in this large data set said they gave up certain foods with the express aim of avoiding a food allergy in their babies,” Dr. Robbins says. “However, mothers who had an older child with a food allergy or who had food allergies themselves had significantly higher odds of trying this food avoidance strategy.”

Despite the diet changes, infants born to these expectant mothers were twice as likely to experience problems with food at age 4 months – though not at age 9 months or 12 months. And these infants were no more likely to be diagnosed with a food allergy.

According to the FDA, millions of Americans suffer a food allergy each year. Reactions can range from mild to life-threatening and can begin soon after eating a problematic food item or an ingredient from that food. Among the most common allergenic foods are milk, eggs, fish, shellfish, tree nuts, peanuts, wheat and soybeans.

“We really need to know more about how often targeted food avoidance occurs among U.S. pregnant women who have a family history of food allergies,” Dr. Robbins adds. “We hope to learn what factors into these women’s decision-making as well as why many of them settled on food avoidance as a potential strategy to try to prevent food allergy in their infants.”

The Leapfrog Group names Children’s National Health System a 2018 “Top Children’s Hospital”

Top Children’s Hospital logo

On December 4, 2018, Children’s National Health System was named a 2018 “Top Children’s Hospital” by The Leapfrog Group, an independent watchdog organization. The highest performing hospitals on the Leapfrog Hospital Survey are recognized annually for this prestigious award. Children’s National is proud to have been recognized 10 times as “Top Children’s Hospital.” Top hospitals are given the designation for having distinct achievements in patient safety and quality, including lower infection rates, decreased length of stay, fewer readmissions and higher survival rates for high-risk procedures.

“We’re particularly proud of this acknowledgment as it recognizes our unwavering commitment to high-quality patient care,” said Kurt Newman, M.D., president and CEO of Children’s National. “It highlights our exceptional clinicians and support teams who work to constantly improve the safety of the care we provide.”

The Top Children’s Hospitals are selected based on The Leapfrog Group’s annual survey of nearly 1,900 hospitals across the country which measures hospitals’ performance in many areas of hospital care, including reduced medication rates and capacity to prevent medication errors.

“Being acknowledged as a Top Children’s Hospital is an incredible feat achieved by less than six percent of eligible hospitals nationwide,” said Leah Binder, president and CEO of The Leapfrog Group. “With this honor, Children’s National has established its commitment to safer and higher quality care. Providing this level of care to patients in Washington, D.C. requires motivation and drive from every team member. I congratulate the board, staff and clinicians, whose efforts made this honor possible.”

MRI and ultrasound imaging detect the spectrum of Zika’s impact

Sarah Mulkey

“A combination of prenatal MRI and US was able to detect Zika-related brain abnormalities during pregnancy, giving families timely information to prepare for the potential complex care needs of these infants,” says Sarah B. Mulkey, M.D., Ph.D.

Worldwide, thousands of babies have been born to mothers who were infected during pregnancy with Zika, a virus associated with neurological deficits, impaired vision and neurodevelopmental disabilities, among other birth defects. These birth defects are sometimes severe, causing lifelong disability. But they’re also relatively rare compared with the overall rates of infection.

Predicting how many Zika-exposed babies would experience neurological birth defects has been challenging.

However, an international study led by Children’s faculty suggests that ultrasound (US) imaging performed during pregnancy and after childbirth revealed most Zika-related brain abnormalities experienced by infants exposed to the Zika virus during pregnancy, according to a prospective cohort study published online Nov. 26, 2018, in JAMA Pediatrics. Some Zika-exposed infants whose imaging had been normal during pregnancy had mild brain abnormalities detected by US and magnetic resonance imaging (MRI) after they were born.

“A combination of prenatal MRI and US was able to detect Zika-related brain abnormalities during pregnancy, giving families timely information to prepare for the potential complex care needs of these infants,” says Sarah B. Mulkey, M.D., Ph.D., a fetal-neonatal neurologist at Children’s National Health System and the study’s lead author. “In our study, we detected mild brain abnormalities on postnatal neuroimaging for babies whose imaging was normal during pregnancy. Therefore, it is important for clinicians to continue to monitor brain development for Zika-exposed infants after birth.”

As of Nov. 20 2018, nearly 2,500 pregnant women in the U.S. had laboratory confirmed Zika infection, and about 2,400 of them had given birth, according to the Centers for Disease Control and Prevention (CDC). While more than 100 U.S. infants were born with Zika-associated birth defects, the vast majority of Zika-exposed U.S. infants were apparently normal at birth. The sequential neuroimaging study Dr. Mulkey leads seeks to determine the spectrum of brain findings in infants exposed to Zika in the womb using both US and MRI before and after birth.

The international research team enrolled 82 women in the study from June 15, 2016, through June 27, 2017. All of the women had been exposed to Zika during pregnancy; all but one experienced clinical symptoms by a mean gestational age of 8.2 weeks. Eighty of those women lived in or near Barranquilla, Colombia, and were exposed to Zika there. Two U.S. study participants were exposed to the primarily mosquito-borne illness during travel to Zika hot zones.

All women received fetal MRIs and US during the second and/or third trimester of pregnancy. After their infants were born, the children received brain MRI and cranial US. Blood samples from both mothers and babies were tested for Zika using polymerase chain reaction and serology.

Fetal MRI was able to discern Zika-related brain damage as early as 18 weeks gestation and picked up significant fetal brain abnormalities not fully appreciated in US imaging. In one case, the US remained normal while fetal MRI alone detected brain abnormalities. Three fetuses (4 percent) had severe fetal brain abnormalities consistent with Zika infection, including:

  • Two cases of heterotopias and malformations in cortical development, and
  • One case of parietal encephalocele, Chiari II malformation and microcephaly.

Seventy-five infants were born at term. One pregnancy was terminated at 23 weeks gestation due to the gravity of the fetal brain abnormalities. One fetus with normal imaging died during pregnancy. One newborn who was born with significant fetal brain abnormalities died at age 3 days.

Cranial US and brain MRI was performed on the majority of infants whose prenatal imaging had been normal.  Seven of 53 (13 percent) Zika-exposed infants had mild brain abnormalities detected by MRI after birth. In contrast, postnatal cranial US was better at detecting changes of lenticulostriate vasculopathy, cysts within the brain’s choroid plexus (cells that produce cerebrospinal fluid), germinolytic/subependymal cysts and/or calcifications, which were seen in 21 of 57 (37 percent) infants.

“Sequential neuroimaging revealed that the majority of Zika-exposed fetuses had normal brain development. Tragically, in a small number of pregnancies, Zika-related brain abnormalities were quite severe,” Dr. Mulkey adds. “Our data support the CDC’s recommendation that cranial US be performed after Zika-exposed babies are born. In addition, there is clearly a need to follow these babies over time to gauge whether the brain anomalies we see in imaging affects language, motor and social skills.”

Disparities in who accesses emergency mental health services

emergency signs

A Children’s research team found the number of children and adolescents visiting the nation’s emergency departments due to mental health concerns continued to rise at an alarming rate from 2012 through 2016, with mental health diagnoses for non-Latino blacks outpacing such diagnoses among youth of other racial/ethnic groups.

The demand for mental health services continues to be high in the U.S., even among children. The Centers for Disease Control and Prevention (CDC) reports that one in seven U.S. children aged 2 to 8 had a diagnosed mental, behavioral or developmental disorder. In addition, 3 percent of U.S. children aged 3 to 17 had a diagnosis of anxiety, and 2.1 were diagnosed with depression, according to the CDC.

Knowing which children use mental health services can help health care providers improve access and provide more targeted interventions.

Children’s researchers recently investigated this question in the emergency room setting, reporting results from their retrospective cross-sectional study at the American Academy of Pediatrics (AAP) 2018 National Conference & Exhibition. The research team found the number of children and adolescents visiting the nation’s emergency departments due to mental health concerns continued to rise at an alarming rate from 2012 through 2016, with mental health diagnoses for non-Latino blacks outpacing such diagnoses among youth of other racial/ethnic groups.

“Access to mental health services among children can be difficult, and data suggest that it can be even more challenging for minority children compared with non-minority youths,” says Monika K. Goyal, M.D., MSCE, assistant division chief and director of research in the Division of Emergency Medicine at Children’s National Health System and the study’s senior author. “Our findings underscore the importance of improving access to outpatient mental health resources as well as expanding capacity within the nation’s emergency departments to respond to this unmet need.”

An estimated 17.1 million U.S. children are affected by a psychiatric disorder, making mental health disorders among the most common pediatric illnesses. Roughly 2 to 5 percent of all emergency department visits by children are related to mental health concerns. The research team hypothesized that within that group, there might be higher numbers of minority children visiting emergency departments seeking mental health services.

To investigate this hypothesis, they examined Pediatric Health Information System data, which aggregates deidentified information from patient encounters at more than 45 children’s hospitals around the nation. Their analyses showed that in 2012, 50.4 emergency department visits per 100,000 children were for mental health-related concerns. By 2016, that figure had grown to 78.5 emergency department visits per 100,000 children.

During that same five-year time span, there were 242,036 visits by children and adolescents 21 and younger with mental health-related issues*. Within that group:

  • The mean age was 13.3
  • Nearly 55 percent were covered by public insurance
  • 78.4 per 100,000 non-Latino black children received mental health-related diagnoses and
  • 51.5 per 100,000 non-Latino white children received mental health-related diagnoses.

“When stratified by race and ethnicity, mental health-related visits to the nation’s emergency departments rose for non-Latino black children and adolescents at almost double the rate seen for non-Latino white children and adolescents,” Dr. Goyal adds. “These children come to our emergency departments in crisis, and across the nation children’s hospitals need to expand mental health resources to better serve these vulnerable patients.”

Because the study did not include reviews of individual charts or interviews with patients or providers, the reason for the disparate demand for mental health resources remains unclear.

*The number of patient visits during the five-year study period was revised on Nov. 1 2018, after updated analyses.

Accident or assault? Pediatric firearm injuries differ by age

ambulance

According to a retrospective, cross-sectional study led by Children’s researchers, younger kids are more likely to be shot by accident, and odds are higher that older youths are victims of an assault involving a firearm.

An increasing number of children are injured by firearms in the U.S. each year, but the reasons these injuries happen vary. According to a new retrospective, cross-sectional study led by Children’s researchers and presented at the American Academy of Pediatrics (AAP) 2018 National Conference & Exhibition, firearm injuries vary by the intent of the person discharging the weapon. Younger kids are more likely to be shot by accident, and odds are higher that older youths are victims of an assault involving a firearm. Efforts to protect children from firearm-related injuries should factor in these differences in intent as legislation and policies are drafted, the study team suggests.

Researchers led by Shilpa J. Patel, M.D., MPH, Children’s assistant professor of pediatrics and emergency medicine, reviewed data aggregated in the Nationwide Emergency Department Sample from 2009 to 2013 looking for emergency department visits to treat firearm-related injuries suffered by children and adolescents 21 and younger. They excluded emergency department visits for firearm-related injuries attributed to air, pellet, BB or paintball guns.

Firearm-related injuries are a leading cause of injury and death for U.S. children. Some 111,839 children and youth were treated in emergency departments for firearm-related injuries, or 22,367 per year when averaged over the five-year study period. Nearly 63 percent of these youths were injured by accident; 30.4 percent were victims of assault; 1.4 percent used a firearm to injure themselves. Of note:

  • 89.3 percent were male
  • Their mean age was 18 (67.3 percent 18 to 21; 27.9 percent 13 to 17; 4.8 percent younger than 12)
  • 1 percent were discharged from the emergency department
  • 30 percent had injuries grave enough to trigger hospital admission and
  • 1 percent died from their injuries.

“Children younger than 12 were more likely to be shot by accident. By contrast, we found that the odds of experiencing firearm-related injuries due to assault were higher for youths aged 18 to 21,” Dr. Patel says. “Physicians can play a powerful role in preventing pediatric firearm-related injuries by routinely screening for firearm access and speaking with families about safe firearm storage and violence prevention,” she adds.

Some 52.1 percent of children with firearm-related injuries lived with families whose median household incomes exceeded $56,486.

A growing list of factors that impact CKD severity for kids

Myriad biological and societal factors can impact the occurrence and accelerate progression of chronic kidney disease for children of African descent – including preterm birth, exposure to toxins during gestation and lower socioeconomic status – and can complicate these children’s access to effective treatments.

Myriad biological and societal factors can impact the occurrence and accelerate progression of chronic kidney disease (CKD) for children of African descent – including preterm birth, exposure to toxins during gestation and lower socioeconomic status – and can complicate these children’s access to effective treatments, according to an invited commentary published in the November 2018 edition of American Journal of Kidney Diseases.

Clinicians caring for “these vulnerable children should be mindful of these multiple competing and compounding issues as treatment options are being considered along the continuum from CKD to kidney failure to transplantation,” writes Marva Moxey-Mims, M.D., chief of the Division of Nephrology at Children’s National Health System.

The supplemental article was informed by lessons learned from The Chronic Kidney Disease in Children (CKiD) longitudinal study and conversations that occurred during the Frank M. Norfleet Forum for Advancement of Health, “African Americans and Kidney Disease in the 21st Century.”

African American children represent 23 percent of the overall population of kids with CKD in the CKiD study. While acquired kidney diseases can get their start during childhood when the diseases betray few symptoms, the full impact of illness may not be felt until adulthood. A number of factors can uniquely affect children of African descent, heightening risk for some kids who already are predisposed to suffering more severe symptoms. These include:

  • Preterm birth. African American children make up 36 percent of patients in CKiD with glomerular disease, which tends to have faster progression to end-stage renal disease. These diseases impair kidney function by weakening glomeruli, which impairs the kidneys’ ability to clean blood. Patients with a high-risk apolipoprotein L1 (APOL1) genotype already are at higher risk for focal segmental glomerulosclerosis (FSGS) and CKD. Researchers hypothesize that preterm birth may represent “a second hit that facilitates the development of glomerular damage resulting from the high-risk genotype.” According to the Centers for Disease Control and Prevention, 1 in 10 U.S. infants in 2016 was born preterm, e.g., prior to 37 weeks gestation.
  • APOL1 genotype. Compared with children who had a low-risk genotype and FSGS, children with a high-risk genotype had higher rates of uncontrolled hypertension, left ventricular hypertrophy, elevated C-reactive protein levels and obesity.
  • Human immunodeficiency viral (HIV) status. About 65 percent of U.S. children with HIV-1/AIDS are African American. In a recent nested case-control study of children infected with HIV in the womb, infants with high-risk APOL1 genotypes were 3.5 times more likely to develop CKD with viral infection serving as “a likely second hit.”
  • Access to kidney transplant. African American adults experience a faster transition to end-stage renal disease and are less likely to receive kidney transplants. African American children with CKD from nonglomerular diseases begin renal replacement therapy 1.6 years earlier than children of other races, after adjusting for socioeconomic status. Their wait for dialysis therapy was 37.5 percent shorter. However, these African American children waited 53.7 percent longer for transplants. Although donor blood types, genetic characteristics and other biological factors each play contributing roles, “these findings may reflect sociocultural and institutional differences not captured by socioeconomic status,” Dr. Moxey-Mims writes.

To alleviate future health care disparities, she suggests that additional research explore the impact of expanding services to pregnant women to lower their chances of giving birth prematurely; early childhood interventions to help boost children’s educational outcomes, future job prospects and income levels; expanded studies about the impact of environmental toxicities on prenatal and postnatal development; and heightened surveillance of preterm infants as they grow older to spot signs of kidney disease earlier to slow or prevent disease progression.

“Clinicians can now begin to take into account genetics, socioeconomic status and the impact of the built environment, rather than blaming people and assuming that their behavior alone brought on kidney disease,” Dr. Moxey-Mims adds. “Smoking, not eating properly and not exercising can certainly make people vulnerable to disease. However, there are so many factors that go into developing a disease that patients cannot control: You don’t control to whom you’re born, where you live or available resources where you live. These research projects will be useful to help us really get to the bottom of which factors we can impact and which things can’t we prevent but can strive to mitigate.”

The article covered in this post is part of a supplement that arose from the Frank M. Norfleet Forum for Advancement of Health: African Americans and Kidney Disease in the 21st Century, held March 24, 2017, in Memphis, Tennessee. The Forum and the publication of this supplement were funded by the Frank M. Norfleet Forum for Advancement of Health, the Community Foundation of Greater Memphis and the University of Tennessee Health Science Center.

Femoral fracture

Broken system? Pain relief for fractures differs by race/ethnicity

Femoral fracture

Data collected by a multi-institutional research team show that kids’ pain from long bone fractures may be managed differently in the emergency department depending on the child’s race and ethnicity.

Children who experience broken bones universally feel pain. However, a new multi-institutional study presented at the American Academy of Pediatrics (AAP) 2018 National Conference & Exhibition suggests that emergency treatment for this pain among U.S. children is far from equal. Data collected by the research team show that kids’ pain may be managed differently in the emergency department depending on the child’s race and ethnicity. In particular, while non-Latino black children and Latino children are more likely to receive any analgesia, non-white children with fractured bones are less likely to receive opioid pain medications, even when they arrive at the emergency department with similar pain levels.

“We know from previously published research that pain may be treated differentially based on a patient’s race or ethnicity in the emergency department setting. Our prior work has demonstrated that racial and ethnic minorities are less likely to receive opioid analgesia to treat abdominal pain, even when these patients are diagnosed with appendicitis,” says study leader Monika K. Goyal, M.D., MSCE, assistant division chief and director of Academic Affairs and Research in the Division of Emergency Medicine at Children’s National Health System. “Emergency departments delivering evidence-based care should treat all pediatric patients consistently. These findings extend our work by demonstrating that children presenting with long bone fractures also experience differential treatment of pain based on their race or ethnicity.”

The AAP calls appropriately controlling children’s pain and stress “a vital component of emergency medical care” that can affect the child’s overall emergency medical experience. Because fractures of long bones – clavicle, humerus, ulna, radius, femur, tibia, fibula – are commonly managed in the emergency department, the research team tested a hypothesis about disparities in bone fracture pain management.

They conducted a retrospective cohort study of children and adolescents 21 and younger who were diagnosed with a long bone fracture from July 1, 2014, through June 30, 2017. They analyzed deidentified electronic health records stored within the Pediatric Emergency Care Applied Research Network Registry, which collects data from all patient encounters at seven pediatric emergency departments.

During that time, 21,642 patients with long bone fractures met the study inclusion criteria and experienced moderate to severe pain, rating four or higher on a 10-point pain scale. Some 85.1 percent received analgesia of any type; 41.5 percent received opioid analgesia. Of note:

  • When compared with non-Hispanic white children, minority children were more likely to receive pain medication of any kind (i.e. non-Latino black patients were 58 percent more likely to receive any pain medication, and Latino patients were 23 percent more likely to receive any pain medication).
  • When compared with non-Latino white children, minority children were less likely to receive opioid analgesia (i.e., non-Latino black patients were 30 percent less likely to receive opioid analgesia, and Latino patients were 28 percent less likely to receive opioid analgesia).

“Even though minority children with bone fractures were more likely to receive any type of pain medication, it is striking that minority children were less likely to receive opioid analgesia, compared with white non-Latino children,” Dr. Goyal says. “While it’s reassuring that we found no racial or ethnic differences in reduction of patients’ pain scores, it is troubling to see marked differences in how that pain was managed.”

Dr. Goyal and colleagues are planning future research that will examine the factors that inform how and why emergency room physicians prescribe opioid analgesics.

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 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.”
