In addition to this COVID-19 special edition event, NCC-PDI recently revealed the ten finalists in its prestigious 8th annual “Make Your Medical Device Pitch for Kids!” competition. Cardiovascular, NICU, and orthopaedic and spine device innovations are the focus of the fall competition, taking place October 7, 2020 as part of the 8th Annual Symposium on Pediatric Device Innovation, presented by Children’s National and co-located with The MedTech Conference powered by AdvaMed.
A simple measuring tape could be the key to identifying which children could develop neurological and developmental abnormalities from Zika virus exposure during gestation. This is according to an invited commentary published July 7, 2020 in JAMA Network Open and written by Sarah Mulkey, M.D., Ph.D., prenatal-neonatal neurologist in the Division of Prenatal Pediatrics at Children’s National Hospital.
Zika virus (ZIKV), first isolated in 1947 in the Ziika Forest in Uganda, made headlines in 2015-2016 for causing a widespread epidemic that spread through parts of North and South America, several islands in the Pacific and parts of Southeast Asia. Although previously linked with no or mild symptoms, researchers discovered during this epidemic that Zika can cross from a pregnant woman to her gestating fetus, leading to a syndrome marked by microcephaly (decreased brain growth), abnormal neurologic tone, vision and hearing abnormalities and joint contractures.
“For the 90% to 95% of ZIKV-exposed infants who fortunately were not born with severe abnormalities at birth and were normocephalic, our hope was that these children would have normal neurodevelopmental outcomes,” Dr. Mulkey writes in the commentary. “Unfortunately, this has not been the case.”
Her commentary expands on a study in the same issue entitled “Association between exposure to antenatal Zika virus and anatomic and neurodevelopmental abnormalities in children” by Cranston et al. In this study, the researchers find that head circumference — a simple measure taken regularly at postnatal appointments in the U.S. — can provide insight into which children were most likely to develop neurologic abnormalities. Their findings show that 68% of those whose head circumference was in the “normal” range at birth developed neurologic problems. Those whose head circumference was at the upper end of this range were significantly less likely to have abnormalities than those at the lower end.
Just this single measurement offers considerable insight into the risk of developing neurologic problems after Zika exposure. However, notes Dr. Mulkey, head circumference growth trajectory is also key. Of the 162 infants whose heads were initially in the normocephalic range at birth, about 10.5% went on to develop microcephaly in the months after birth.
“Because early head growth trajectory is associated with cognitive outcomes in early childhood,” Dr. Mulkey writes, “following the head circumference percentile over time can enable recognition of a child with increased risk for poor outcome who could benefit from early intervention therapies.”
This simple assessment could be significantly augmented with neuroimaging, she adds. The study by Cranston et al., as well as others in the field, have shown that brain imaging often reveals problems in ZIKV-exposed children, such as calcifications and cerebral atrophy, even in those with normal head circumferences. This imaging doesn’t necessarily need to take place at birth, Dr. Mulkey says. Postnatal development of microcephaly, failure to thrive or developmental delay can all be triggers for imaging later on.
Together, Dr. Mulkey says, the study by Cranston et al. and others that focus on ZIKV-exposed children support the need for following these patients long term. Children exposed to ZIKV in the epidemic nearly five years ago are now approaching school age, a time fraught with more complicated cognitive and social demands. Through her own research at Children’s National’s Congenital Zika Virus Program and collaboration with colleagues in Colombia, Dr. Mulkey is following multiple cohorts of ZIKV exposed children as they grow. She recently published a study on neurological abnormalities in one of these cohorts in JAMA Pediatrics in January 2020.
“It’s really important to follow these children as long as possible so we’ll really know the outcomes of this virus,” Dr. Mulkey says.
Children’s National Hospital in Washington, D.C., was ranked No. 7 nationally in the U.S. News & World Report 2020-21 Best Children’s Hospitals annual rankings. This marks the fourth straight year Children’s National has made the list, which ranks the top 10 children’s hospitals nationwide.
In addition, its neonatology program, which provides newborn intensive care, ranked No.1 among all children’s hospitals for the fourth year in a row.
For the tenth straight year, Children’s National also ranked in all 10 specialty services, with seven specialties ranked in the top 10.
“Our number one goal is to provide the best care possible to children. Being recognized by U.S. News as one of the best hospitals reflects the strength that comes from putting children and their families first, and we are truly honored,” says Kurt Newman, M.D., president and CEO of Children’s National Hospital.
“This year, the news is especially meaningful, because our teams — like those at hospitals across the country — faced enormous challenges and worked heroically through a global pandemic to deliver excellent care.”
“Even in the midst of a pandemic, children have healthcare needs ranging from routine vaccinations to life-saving surgery and chemotherapy,” said Ben Harder, managing editor and chief of Health Analysis at U.S. News. “The Best Children’s Hospitals rankings are designed to help parents find quality medical care for a sick child and inform families’ conversations with pediatricians.”
The annual rankings are the most comprehensive source of quality-related information on U.S. pediatric hospitals. The rankings recognize the nation’s top 50 pediatric hospitals based on a scoring system developed by U.S. News. The top 10 scorers are awarded a distinction called the Honor Roll.
The bulk of the score for each specialty service is based on quality and outcomes data. The process includes a survey of relevant specialists across the country, who are asked to list hospitals they believe provide the best care for patients with the most complex conditions.
Below are links to the seven Children’s National specialty services that U.S. News ranked in the top 10 nationally:
- Neonatology (No. 1), led by Division Chief Billie Lou Short, M.D.
- Neurology and Neurosurgery (No. 3), led by Division Chiefs William D. Gaillard, M.D., and Robert F. Keating, M.D.
- Cancer (No. 6), led by Division Chief Jeffrey S. Dome, M.D., Ph.D.
- Nephrology (No. 7), led by Division Chief Marva Moxey-Mims, M.D., FASN
- Orthopedics (No. 9), led by Division Chief Matthew Oetgen, M.D., MBA
- Pulmonology and Lung Surgery (No.9), led by Division Chief Anastassios Koumbourlis, M.D., MPH
- Diabetes and Endocrinology (No. 10), led by Division Chief Andrew Dauber, M.D., MMSC
Since the beginning of the COVID-19 pandemic, there has been a dramatic increase in advance care planning (ACP) and the creation of advance directives, also known as living wills, in the United States. New research, published in AIDS and Behavior, shows the effectiveness of an ACP model developed through participatory research with adolescents in improving palliative care among adult people living with HIV (PLWH).
These findings demonstrate that ACP positively contributes to the palliative care of adult PLWH by relieving suffering and maximizing quality of life. The intervention was based on the FAmily CEntered (FACE) Advance Care Model, which was developed and tested by principal investigator Maureen E. Lyon, Ph.D., and her colleagues.
Dr. Lyon’s team used this model successfully with adolescents living with HIV as part of five-year, five-site trial that included Children’s National Hospital. The trial was co-funded by the National Institutes of Health and National Institute of Nursing Research. The success of that study was parlayed into a new five-year study testing a slightly modified ACP intervention in adults, with Children’s National serving as the coordinating center. “The adolescents showed us the way,” says Dr. Lyon.
The paper details the findings of a longitudinal, two arm, randomized controlled clinical trial examining whether an ACP intervention aimed at adult PLWH and their families correlated with higher congruence in treatment preferences, as well as higher congruence over time. Patient-surrogate dyads were randomized to an ACP intervention arm or an active control arm at a 2:1 ratio (86 intervention dyads and 43 control dyads at 18-month follow up), due to prior demonstrated benefit of ACP.
The ACP intervention consisted of two 60-minute, patient-focused sessions. During session 1, Respecting Choices Next Steps® ACP Conversation, both patients and their surrogate decision-makers focused on the patients’ understanding of HIV, experience of symptoms, fears, hopes and worries. Next, a patient’s treatment preferences were explored via the Statement of Treatment Preferences (SoTP), which became a part of the patient’s electronic health record (EHR). Surrogates were questioned on their comprehension and willingness to comply with the patient’s wishes. Session 1 was acknowledged as the beginning of a conversation, and continued conversation between the dyad was encouraged.
Session 2, Five Wishes©, involved a facilitator guiding the dyad through a Five Wishes© advance directive. Session 2 resulted in legal documentation of a patient’s preferences in five specific areas: The patient’s preferred health care decision-maker, the kind of medical treatment the patient wants, how comfortable the patient wants to be, how the patient wants people to treat him/her and what the patient wants loved ones to know. The patient, surrogate and treating physicians all received a copy, and a copy was also submitted to the patient’s EHR.
Dyads in the control arm participated in two 60-minute sessions entitled Developmental or Relationship History (excluding any medical questions) and Nutrition & Exercise.
The researchers then assessed treatment preference congruence for each patient-surrogate dyad by presenting them with five different hypothetical scenarios. After the first session, congruence across all scenarios was significantly higher among ACP intervention dyads compared to control dyads. ACP patients were also significantly more likely to give their surrogates leeway in treatment decision making compared to control patients.
Compared to control dyads, ACP dyads were significantly more likely to maintain High → High congruence transition and significantly less likely to experience Low → Low congruence transition as measured from immediately post-intervention to 12-months post-intervention. The only two cases of Low → High congruence transition occurred in the intervention arm. Of note, ACP surrogates accurately reported on changes in patient preferences over one year, showing the positive impact of early conversation on longitudinal congruence.
Dr. Lyon hopes these results will encourage people to talk to their loved ones as soon as possible about ACP, not only during the current pandemic but into the future. “People can use what’s happening in the news as a trigger to begin these conversations,” she says. “The 1990 Patient Self-Determination Act (PSDA) encourages persons of all ages– including children and their parents– to decide the type and extent of medical care they want to accept or refuse if they become unable to make those decisions due to illness. Our research shows conversations matter.”
The original research paper, “Effect of FAmily CEntered (FACE®)Advance Care Planning on Longitudinal Congruence in End-of-Life Treatment Preferences: A Randomized Clinical Trial,” was recently published in AIDS and Behavior. Dr. Maureen E. Lyon, Ph.D., FABPP, of the Center for Translational Research/Children’s Research Institute, was the principal investigator of the trial and a co-senior of the paper.
Pediatric orthopaedic surgery as a field is focused on improving quality and value in pediatric spine surgery, especially when it comes to eliminating surgical site infections (SSI). Many studies have documented how and why surgical site infections occur in pediatric spinal fusion patients, however, there is very little data about what approaches are most effective at reducing SSIs for these patients in a sustainable way.
At the Pediatric Orthopaedic Society of North America’s 2020 Annual Meeting, Matthew Oetgen, M.D., MBA, chief of orthopaedic surgery and sports medicine at Children’s National Hospital, presented findings from a long-term single institution study of acute SSI prevention measures.
“These findings give us specific insight into the tactics that are truly preventing, and in our case sometimes even eliminating, SSIs for pediatric scoliosis surgery,” says Dr. Oetgen, who also served on the annual meeting program committee. “By analyzing patient records across more than a decade, we were able to see that some strategies are quite effective, and others, that we thought would move the needle, just don’t.”
The team reviewed medical records and radiographs dating back to 2008 for 1,195 patients who had spinal fusion for scoliosis, including idiopathic scoliosis as well as other forms such as neuromuscular or syndromic scoliosis. Over that period of time, the division of orthopaedics and sports medicine at Children’s National was collaborating with the hospital’s infection control team to achieve several programmatic implementation milestones, including:
- January 2012: Standardized infection surveillance program
- July 2013: Standardized perioperative infection control protocols including those for pre-operative surgical site wash, surgical site preparation and administration of antibiotics before and after surgery
- March 2015: Standardized comprehensive spinal care pathway including protocols for patient temperature control, fluid and blood management, and drain and catheter management
Over the study time period, the team found that SSIs did decrease, but interestingly, the rate did not progressively decrease with each subsequent intervention.
“Instead, we found that the rate went down and was even eliminated for some subgroups when the perioperative infection control protocols were implemented in 2013 and sustained through the study period end,” says Dr. Oetgen. “The other programmatic efforts that started in 2012 and 2015 had no impact on infection rates.”
He also notes that the study’s findings have identified a crucial component in the process for infection control in pediatric spinal surgery—perioperative protocols. “A relatively uncomplicated perioperative infection control protocol did the best job decreasing SSI in spinal fusion. Future efforts to optimize this particular protocol may help improve the rates even further.”
POSNA’s Annual Meeting content, including Dr. Oetgen’s presentation, is available from May 13, 2020 through December 31, 2020.
The Children’s National Research Institute recently released its 2019-2020 academic annual report, titled 150 Years Stronger Through Discovery and Care to mark the hospital’s 150th birthday. Not only does the annual report give an overview of the institute’s research and education efforts, but it also gives a peek in to how the institute has mobilized to address the coronavirus pandemic.
“Our inaugural research program in 1947 began with a budget of less than $10,000 for the study of polio — a pressing health problem for Washington’s children at the time and a pandemic that many of us remember from our own childhoods,” says Vittorio Gallo, Ph.D., chief research officer at Children’s National Hospital and scientific director at Children’s National Research Institute. “Today, our research portfolio has grown to more than $75 million, and our 314 research faculty and their staff are dedicated to finding answers to many of the health challenges in childhood.”
Highlights from the Children’s National Research Institute annual report
- In 2018, Children’s National began construction of its new Research & Innovation Campus (CNRIC) on 12 acres of land transferred by the U.S. Army as part of the decommissioning of the former Walter Reed Army Medical Center campus. In 2020, construction on the CNRIC will be complete, and in 2012, the Children’s National Research Institute will begin to transition to the campus.
- In late 2019, a team of scientists led by Eric Vilain, M.D., Ph.D., director of the Center for Genetic Medicine Research, traveled to the Democratic Republic of Congo to collect samples from 60 individuals that will form the basis of a new reference genome data set. The researchers hope their project will generate better reference genome data for diverse populations, starting with those of Central African descent.
- A gift of $5.7 million received by the Center for Translational Research’s director, Lisa Guay-Woodford, M.D., will reinforce close collaboration between research and clinical care to improve the care and treatment of children with polycystic kidney disease and other inherited renal disorders.
- The Center for Neuroscience Research’s integration into the infrastructure of Children’s National Hospital has created a unique set of opportunities for scientists and clinicians to work together on pressing problems in children’s health.
- Children’s National and the National Institute of Allergy and Infectious Diseases are tackling pediatric research across three main areas of mutual interest: primary immune deficiencies, food allergies and post-Lyme disease syndrome. Their shared goal is to conduct clinical and translational research that improves what we know about those conditions and how we care for children who have them.
- An immunotherapy trial has allowed a little boy to be a kid again. In the two years since he received cellular immunotherapy, Matthew has shown no signs of a returning tumor — the longest span of time he’s been tumor-free since age 3.
- In the past 6 years, the 104 device projects that came through the National Capital Consortium for Pediatric Device Innovation accelerator program raised $148,680,256 in follow-on funding.
- Even though he’s watched more than 500 aspiring physicians pass through the Children’s National pediatric residency program, program director Dewesh Agrawal, M.D., still gets teary at every graduation.
Understanding and treating the novel coronavirus (COVID-19)
In a short period of time, Children’s National Research Institute has mobilized its scientists to address COVID-19, focusing on understanding the virus and advancing solutions to ameliorate the impact today and for future generations. Children’s National Research Institute Director Mark Batshaw, M.D., highlighted some of these efforts in the annual report:
- Eric Vilain, M.D., Ph.D., director of the Center for Genetic Medicine Research, is looking at whether or not the microbiome of bacteria in the human nasal tract acts as a defensive shield against COVID-19.
- Catherine Bollard, M.D., MBChB, director of the Center for Cancer and Immunology Research, and her team are seeing if they can “train” T cells to attack the invading coronavirus.
- Sarah Mulkey, M.D., Ph.D., an investigator in the Center for Neuroscience Research and the Fetal Medicine Institute, is studying the effects of, and possible interventions for, coronavirus on the developing brain.

In contrast to the prevailing view that the novel coronavirus known as COVID-19 does not seriously impact children, a new study finds that children who contract the virus can become very ill—many of them critically so, according to physician researchers at Children’s National Hospital. Their results, published in the Journal of Pediatrics and among the first reports from a U.S. institution caring for children and young adults, shows differences in the characteristics of children who recovered at home, were hospitalized, or who required life support measures. These findings highlight the spectrum of illness in children, and could help doctors and parents better predict which pediatric patients are more likely to become severely ill as a consequence of the virus.
In late 2019, researchers identified a new coronavirus, known as SARS-CoV-2, which causes COVID-19. As the disease spread around the world, the vast majority of reports suggested that elderly patients bear the vast majority of the disease burden and that children are at less risk for either infection or severe disease. However, study leader Roberta DeBiasi, M.D., M.S., chief of the Division of Infectious Diseases at Children’s National, states that she and her colleagues began noticing an influx of children coming to the hospital for evaluation of a range of symptoms starting in mid-March 2020, who were tested and determined to be infected with COVID-19. One quarter of these children required hospitalization or life support.
“It was very apparent to us within the first several weeks of the epidemic that this was a very different situation than our colleagues on the West Coast of the US had described as their experience just weeks before,” DeBiasi says. “Right away, we knew that it was important for us to not only care for these sick children, but to examine the factors causing severe disease, and warn others who provide medical care to children.”
To better understand this phenomenon, she and her colleagues examined the medical records of symptomatic children and young adults who sought treatment at Children’s National for COVID-19 between March 15 and April 30, 2020. Each of these 177 children tested positive using a rapid assay to detect SARS-CoV-2 performed at the hospital. The researchers gathered data on each patient, including demographic details such as age and sex; their symptoms; whether they had any underlying medical conditions; and whether these patients were non-hospitalized, hospitalized, or required critical care.
The results of their analysis show that there was about an even split of male and female patients who tested positive for COVID-19 at Children’s National during this time period. About 25% of these patients required hospitalization. Of those hospitalized, about 75% weren’t considered critically ill and about 25% required life support measures. These included supplemental oxygen delivered by intubation and mechanical ventilation, BiPAP, or high-flow nasal cannula – all treatments that support breathing – as well as other support measures such as dialysis, blood pressure support and medications to treat infection as well as inflammation.
Although patients who were hospitalized spanned the entire age range, more than half of them were either under a year old or more than 15 years old. The children and young adults over 15 years of age, Dr. DeBiasi explains, were more likely to require critical care.
About 39% of all COVID-19 patients had underlying medical conditions, including asthma, which has been highlighted as a risk factor for worse outcomes with this infection. However, DeBiasi says, although underlying conditions were more common as a whole in hospitalized patients – present in about two thirds of hospitalized and 80% of critically ill – asthma didn’t increase the risk of hospitalization or critical illness. On the other hand, children with underlying neurological conditions, such as cerebral palsy, microcephaly, or global developmental delay, as well as those with underlying cardiac, hematologic, or oncologic conditions were significantly more likely to require hospitalization.
In addition, although early reports of COVID-19 suggested that fever and respiratory symptoms are hallmarks of this infection, Dr. DeBiasi and her colleagues found that fewer than half of patients had both concurrently. Those with mild, upper respiratory symptoms, such as runny nose, congestion, and cough were less likely to end up hospitalized than those with more severe respiratory symptoms, such as shortness of breath. The frequency of other symptoms including diarrhea, chest pain and loss of sense of smell or taste was similar among hospitalized and non-hospitalized patients.
Dr. DeBiasi notes that although other East Coast hospitals are anecdotally reporting similar upticks in pediatric COVID-19 patients who become seriously ill, it’s currently unclear what factors might account for differences from the less frequent and milder pediatric illness on the West Coast. Some factors might include a higher East Coast population density, differences between the genetic, racial and ethnic makeup of the two populations, or differences between the viral strains circulating in both regions (an Asian strain on the West Coast, and a European strain on the East Coast).
Regardless, she says, the good news is that the more researchers learn about this viral illness, the better prepared parents, medical personnel and hospitals will be to deal with this ongoing threat.
Other researchers from Children’s National who participated in this study include Xiaoyan Song, Ph.D., M.Sc., Meghan Delaney, D.O., M.P.H., Michael Bell, M.D. , Karen Smith, M.D., Jay Pershad, M.D., Emily Ansusinha, Andrea Hahn, M.D., M.S., Rana Hamdy, M.D., M.P.H., MSCE, Nada Harik, M.D., Benjamin Hanisch, M.D., Barbara Jantausch, M.D., Adeline Koay, MBBS, MS.c., Robin Steinhorn, Kurt Newman, M.D. and David Wessel, M.D.
During the COVID-19 pandemic, telehealth has been crucial in allowing doctors to maintain safe contact with patients who require ongoing medical care without an office visit. Just as important is the role that telehealth is playing to connect care providers with each other to ensure that everyone around the world has the information they need to provide the best care possible for this swift-moving disease.
One good example of this specialist-to-specialist thought leadership connection is the ongoing weekly meeting hosted by the Children’s National Hospital cardiac critical care specialists. Since early in the spread of COVID-19, the Cardiac-ICU team, led by cardiovascular specialists including Ricardo Munoz, M.D., chief of cardiac critical care medicine and executive director of telehealth at Children’s National, have connected pediatric clinicians around the world to discuss how best to care for particularly vulnerable patients with pre-existing heart diseases, and to discuss breaking news in epidemiology of the disease and the effectiveness of various treatment approaches.
The video conference attracts hundreds of physicians and nurses who specialize in pediatric cardiac care from countries all over the world. In the last week of April, the meeting featured a late-breaking session to discuss new pediatric intensive care observations of inflammatory symptoms similar to Kawasaki disease, which were being detected in the United Kingdom, Paris and the United States. While more information is needed about this discovery, the ability of these experts to gather and compare disease phenotypes from country to country facilitates both the additional classification of pediatric-related symptoms and improves how all centers, no matter their location, can prepare to treat children who present locally with these symptoms.
In recent weeks, cardiac physicians and nurses from some of the world’s hardest hit regions, including Italy and Spain, have shared detailed information about their on-the-ground experiences to help colleagues in the U.S. and elsewhere better prepare for new developments.
“This new disease is a moving target, especially when it comes to understanding how it might impact children and adults with existing cardiac disease, particularly those with congenital heart disease,” says Dr. Munoz. “It is extremely important that we learn from each other, especially when we are able to connect with our colleagues in the epicenters of the most serious outbreaks of COVID-19. We are happy to host this important weekly meeting with the goal of helping every specialist keep as many patients with cardiac diseases as safe as possible throughout the global health emergency.”

The International Consortium for Health Outcomes Measurement (ICHOM) announced the release of a Congenital Heart Disease Standard Set (CHDSS) in late April 2020.
Gerard Martin, M.D., FAAP, FACC, FAHA, cardiologist at Children’s National Hospital, chaired the working group and contributed to the standards’ writing. In ICHOM‘s press release, he noted that, “Having a global set of outcomes that matters most to adult patients and parents of children with congenital heart disease will provide a road map for healthcare professionals and organizations engaged in setting care strategies for this population around the world. I would like to acknowledge the efforts of the Working Group and ICHOM staff for their incredible effort on this project.”
The CHDSS is a minimum core set of standards, comprised of Patient, Parent, and Clinician – Reported Outcome Measures already being collected by most practices in routine clinical care. The CHDSS measures 14 outcomes under the ICHOM framework for comprehensive outcomes measurement. These overarching domains are Overall Health, Social Health, Mental Health, and Physical Health.

The first ever set of specific recommendations to support transgender autistic young people was co-created by these youth and their families working hand-in-hand with clinical experts. The resulting model offers clinicians a set of concrete ways to provide this unique population the support they need.
The recommendations, A Clinical Program for Transgender and Gender-Diverse Neurodiverse/Autistic Adolescents Developed through Community-Based Participatory Design, were published by the Journal of Clinical Child and Adolescent Psychology on May 4, 2020.
“The idea of patients helping to co-design their own care isn’t new, but including the perspectives of autistic youth in their own care is quite new,” says John Strang, Psy.D., who directs the Gender and Autism Program within the Center for Autism Spectrum Disorders at Children’s National Hospital.
He continues, “And for the many youth who are both transgender and autistic, including their voices and perspectives in their clinical care is critical. Without their input, there is a great risk for misunderstanding their needs – and for marginalization.”
“This was an important process in which to participate, and will hopefully help those — autistic people, trans people, and autistic trans people alike — who often only see themselves represented by cisgender, neurotypical researchers and providers. It is a relief to be a part of creating something like this,” adds Marisa Alexa McCool, a co-researcher who is an autistic transgender woman.
The new publication builds on previously published broad clinical guidelines for providers, now integrating the perspectives of autistic transgender individuals themselves. The program includes specific approaches for supporting young people in their diverse needs, and identifies three key components central to this care:
- Helping autistic, gender-diverse young people build community together, which they need and often want, in contrast to clichés about lack of desire for social contact in autism. Many autistic transgender young people prior to entering clinical care have never met another person who is transgender and autistic. The connections that they built with one another through this new clinical care model were critical in helping them develop a positive sense of identity and to know that they are not alone in this world.
- Introducing the youth to a broad spectrum of gender diverse and/or neurodiverse role models helps make possibilities for their future more concrete, and builds a sense of hopefulness and pride. Abstract concepts such as gender or future gender can be particularly challenging for autistic youth. The new care model addresses this by providing these youth opportunities to meet and interact with a range of living role models who represent various gender identities as well as neurodiversity experiences. “Being able to see and hear about the diverse journeys of adults who have already navigated gender and/or autism-related diversity has been helpful in making the various options more tangible for gender diverse autistic youth,” says Dr. Strang. “The chance to meet role models with different gender-related experiences – transgender, cisgender, exploring – has helped autistic gender diverse youth to better figure out what is most true for them and what they need from us.”
- Supporting the gender expression needs of autistic transgender youth through gender style coaching. Because of autism-related sensory sensitivities and problems with planning and social understanding, autistic transgender young people often have difficulty achieving their desired gender transition. Gender-style coaching can help autistic youth reach their gender-related goals in ways that accommodate and support the young person’s autism-related challenges.
The perspectives included in the new clinical program were from a range of ages and backgrounds, as well as across multiple points in time to make sure that as youths’ own views evolved, their evolving needs were captured as well.
The authors created a specific clinical guide to complement the publication, which is available on the Children’s National website.
“We’re so happy to have been able to partner with self-advocates from the autistic transgender and gender diverse communities, youth who are living this experience, and their families, to co-create a community-driven model that can be used for kids seeking guidance and support,” says Dr. Strang.
“We hear over and over again that what parents and care providers really need are concrete tools to support young people with co-occurring autism and gender diversity, so that’s what we sought to do here,” he concludes. “It’s exciting because, for the first time, we have some simple tools to support these kids. And this is critical, because although the co-occurrence of autism and gender diversity has been of great interest to researchers, nearly all studies to date have focused on how many transgender youth are autistic, instead of how to help and support this poorly understood group.”
In early March as countries around the globe began to wrestle with how best to tackle the spread of COVID-19, a group of doctors, nurses, researchers and other medical staff from Children’s National Hospital were wrestling with a distinct set of challenges: What to do about the 10 Ugandan children and adults who were currently scheduled for lifesaving heart surgery (and the countless others who would benefit from the continued training of the local heart surgery team) to correct complications of rheumatic heart disease (RHD) during an impending medical mission in the country.
Rheumatic heart disease impacts over 39 million people globally and causes nearly 300,000 deaths per year. RHD is the result of frequent, untreated streptococcal throat infections in childhood that ultimately cause the body’s immune system to repeatedly damage heart valves. It is completely preventable, yet the majority of the world’s children still live in impoverished and overcrowded conditions that predispose them to RHD. Most patients present with advanced valvular heart disease. For example, in Uganda, an RHD registry includes over 600 children with clinical RHD, of which nearly 40% die within four years and the median survival time from enrollment in the registry is only nine months. For these patients, heart surgery is the only viable solution for long-term survival and normal quality of life.
The scheduled trip from Washington was part of a nearly 20-year partnership** between doctors, nurses, researchers and other medical staff in the United States, including Craig Sable, M.D., associate chief of cardiology, and and Pranava Sinha, M.D.,pediatric cardiovascular surgeon, at Children’s National Hospital in Washington, D.C., and the Uganda Heart Institute in Kampala, Uganda. The partnership aims to tackle RHD head-on. It provides surgical skill transfer, allows for treatment of more complex patients, and increases sustainable surgical capacity for Uganda’s RHD patients over time. As a result, over the last 15 years more than 1,000 children have received lifesaving heart surgery in Uganda, with the Uganda Heart Institute (UHI) performing one to two heart valve surgeries every two weeks over the last few years.
COVID-19 was changing the current plan, however. Travel between countries was limited, and the team from the U.S. wouldn’t have been permitted to leave the U.S. and return according to schedule. The trip, and the support teams who were scheduled to arrive to help with the surgeries, were cancelled. The U.S. team members who had already arrived in Uganda were sent home after helping their UHI colleagues set up and prepare for the surgeries as much as possible. Knowing that patients and families were counting on the surgery mission to go forward after waiting for months or years to have surgery for heart valve disease, UHI decided not to cancel the majority of the surgeries. Instead, for the first time, they planned and successfully completed five valve-related cases in a single week – several of them quite complex. The cardiologists and cardiac surgeons from Children’s National who were supposed to be in-country for these procedures were forced to limit their in person assistance to the set-up activities the week prior to surgery and telehealth consult during the procedures.
“It was hard not to be able to stay and work with the UHI team to help these families,” says Dr. Sable. “But we are so proud of the UHI team for meeting this challenge on their own. We knew they had the skills to perform at this volume and complexity. It’s a proud moment to see the team accomplish this major milestone, and to see the patients they cared for thrive.”
The patients are the most important outcome: The five who had successful open-heart surgery are all doing well, either on their way to recovery or already discharged to their communities, where they will, for the first time in memory, be able to play, exercise and go to school or work.
Longer term, this success demonstrates the UHI medical team’s ability to manage greater surgical capacity even when surgical missions from the U.S. resume. The partnership’s goal is to complete at least 1,000 annual operations (both pediatric and adult), with the majority being performed by the local team. Having this capacity available will mean the difference between life and death for many children and adults who have RHD in Uganda and the surrounding countries.

Newborn screening (NBS) programs are critical to public health. Run at the state-level, mandatory NBS programs detect a host of hereditary disorders so that infants can be treated before further damage, or even death, occurs.
While much attention is paid to testing technology, programs must still meet basic minimum requirements to reliably identify and treat all affected individuals including minimum reporting requirements, case surveillance and a dedicated short-term follow-up program. In newborn screening, success is systematic.
A new report “How a baby with classic galactosemia was nearly missed: When the test succeeds but system fails,” published in the American Journal of Medical Genetics, takes a look at an individual case that almost slipped through the cracks of a local NBS program.
One disorder detected by NBS is classic galactosemia (CG), which arises from a deficiency in the galactose-1-phosphate uridyltransferase (GALT) enzyme, leaving infants unable to metabolize galactose-1-phosophate, a monosaccharide abundantly present in milk. CG can result in fatal liver failure, sepsis and coagulopathy if the affected infant is not switched to soy-based formula within the first week of life.
CG can be detected through a combination of enzyme assay, DNA analysis and galactose quantification. However, NBS programs differ in testing protocols for CG by state, and not all NBS programs conduct all of these tests. This is of particular relevance to the Washington, D.C., metropolitan area, a regional nexus where crossing state and district lines for medical care is common.
The report describes how a D.C.-born infant was screened for CG through all three tests. While his galactose levels were normal, his GALT was low and DNA testing revealed homozygosity for a CG mutation known as K285N. In tandem, the latter two indicators constitute a true positive result for CG, and necessitate the proper issuance of referrals, precautions and follow-up, which failed to occur in this case.
The infant breastfed and displayed notable lethargy, and parents were directed to a local emergency department in a neighboring state which does not screen for CG with DNA testing.
The providers there were unfamiliar with the DNA results, and after new labs came back normal, the NBS results were deemed as “likely falsely positive” for CG. Fortunately, a provider at the community hospital forwarded the NBS results to the Children’s National Rare Disease Institute (CNRDI). Upon review, CNRDI metabolic specialists immediately sought to rectify the situation by reaching out to the family with proper instructions and arranging a clinical evaluation, which occurred 10 days after birth.
While this case had a fortunate ending, the report highlights the potential deficiencies in NBS programs, which have historically been among America’s most successful public health initiatives. The proper and timely functioning of NBS systems is contingent upon the functioning of its constituent parts, including testing, diagnosis, follow-up, management and stakeholder education.
While test results were accurate in this case, systemic shortcomings left a patient in danger. As the authors state, “Programs must keep in mind that the true success of newborn screening extends beyond just the test itself…to improve safety and care outcomes we must focus on the system.”
A clinical report by a team of authors, mainly comprised of Children’s National clinicians, was published earlier this month in the American Journal of Medical Genetics. Authors include Sarah Viall, PPCNP, MSN, a pediatric nurse practitioner in the Rare Disease Institute; Nicholas Ah Mew, M.D., director of the Inherited Metabolic Disorders Program; and Beth A. Tarini, M.D., M.S., associate director of the Center for Translational Research.
Boys with Duchenne muscular dystrophy (DMD) experience poor muscle regeneration, but the precise reasons for this remain under investigation. An experimental model of severe DMD that experiences a large spike in transforming growth factor-beta (TGFβ) activity after muscle injury shows that high TGFβ activity suppresses muscle regeneration and promotes fibroadipogenic progenitors (FAPs). This leads to replacement of the damaged muscle fibers by calcified and connective tissue, compromising muscle structure and function. While blocking FAP buildup provides a partial solution, a Children’s National Hospital study team identifies correcting the muscle micro-environment caused by high TGFβ as a ripe therapeutic target.
The team’s study was published online March 26, 2020, in JCI Insight.
DMD is a chronic muscle disease that affects 1 in 6,200 young men in the prime of their lives. The disorder, caused by genetic mutations leading to the inability to produce dystrophin protein, leads to ongoing muscle damage, chronic inflammation and poor regeneration of lost muscle tissue. The patients experience progressive muscle wasting, lose the ability to walk by the time they’re teenagers and die prematurely due to cardiorespiratory failure.
The Children’s National team finds for the first time that as early as preadolescence (3 to 4 weeks of age), their experimental model of severe DMD disease showed clear signs of the type of spontaneous muscle damage, regenerative failure and muscle fiber loss seen in preadolescent boys who have DMD.
“In boys, the challenge due to muscle loss exists from early in their lives, but had not been mimicked previously in experimental models,” says Jyoti K. Jaiswal, MSc, Ph.D., principal investigator in the Center for Genetic Medicine Research at Children’s National, and the study’s co-senior author. “TGFβ is widely associated with muscle fibrosis in DMD, when, in fact, our work shows its role in this disease process is far more significant.”
Research teams have searched for experimental models that replicate the sudden onset of symptoms in boys who have DMD as well as its complex progression.
“Our work not only offers insight into the delicate balance needed for regeneration of skeletal muscle, but it also provides quantitative information about muscle stem cell activity when this balanced is disturbed,” says Terence A. Partridge, Ph.D., principal investigator in the Center for Genetic Medicine Research at Children’s National, and the study’s co-senior author.
“The D2-mdx experimental model is a relevant one to use to investigate the interplay between inflammation and muscle degeneration that is seen in humans with DMD,” adds Davi A.G. Mázala, co-lead study author. “This model faithfully recapitulates many features of the complex disease process seen in humans.”
Between 3 to 4 weeks of age in the experimental models of severe DMD disease, the level of active TGFβ spiked up to 10-fold compared with models with milder disease. Intramuscular injections of an off-the-shelf drug that inhibits TGFβ signaling tamped down the number of FAPs, improving the muscle environment by lowering TGFβ activity.
“This work lays the foundation for studies that could lead to future therapeutic strategies to improve patients’ outcomes and lessen disease severity,” says James S. Novak, Ph.D., principal investigator in Children’s Center for Genetic Medicine Research, and co-lead study author. “Ultimately, our goal is to improve the ability of patients to continue to maintain muscle mass and regenerate muscle.”
In addition to Mázala, Novak, Jaiswal and Partridge, Children’s National study co-authors include Marshall W. Hogarth; Marie Nearing; Prabhat Adusumalli; Christopher B. Tully; Nayab F. Habib; Heather Gordish-Dressman, M.D.; and Yi-Wen Chen, Ph.D.

At a pivotal moment early in his career, Vittorio Gallo, Ph.D., was accepted to work with Professor Giulio Levi at the Institute for Cell Biology in Rome, a position that leveraged courses Gallo had taken in neurobiology and neurochemistry, and allowed him to work in the top research institute in Italy directed by the Nobel laureate, Professor Rita Levi-Montalcini.
For four years as a student and later as Levi’s collaborator, Gallo focused on amino acid neurotransmitters in the brain and mechanisms of glutamate and GABA release from nerve terminals. Those early years cemented a research focus on glutamate neurotransmission that would lead to a number of pivotal publications and research collaborations that have spanned decades.
Now, investigators from around the world who have worked most closely with Gallo penned tributes in the form of manuscripts that were assembled in a special issue of “Neurochemical Research” that honors Gallo “for his contributions to our understanding of glutamatergic and GABAergic transmission during brain development and to his leadership in the field of neural development and regeneration,” writes guest editor Arne Schousboe, of the University of Copenhagen in Denmark.
“In spite of news headlines about competition in research and many of the negative things we hear about the research world, this shows that research is also able to create a community around us,” says Gallo, chief research officer at Children’s National Hospital and scientific director for the Children’s National Research Institute.
As just one example, he first met Schousboe 44 years ago when Gallo was a 21-year-old mustachioed graduate student.
“Research can really create a sense of community that we carry on from the time we are in training, nurture as we meet our colleagues at periodic conferences, and continue up to the present. Creating community is bi-directional: influencing people and being influenced by people. People were willing to contribute these 17 articles because they value me,” Gallo says. “This is a lot of work for the editor and the people who prepared papers for this special issue.”
In addition to Gallo publishing more than 140 peer-reviewed papers, 30 review articles and book chapters, Schousboe notes a number of Gallo’s accomplishments, including:
- He helped to develop the cerebellar granule cell cultures as a model system to study how electrical activity and voltage-dependent calcium channels modulate granule neuron development and glutamate release.
- He developed a biochemical/neuropharmacological assay to monitor the effects of GABA receptor modulators on the activity of GABA chloride channels in living neurons.
- He and Maria Usowicz used patch-clamp recording and single channel analysis to demonstrate for the first time that astrocytes express glutamate-activated channels that display functional properties similar to neuronal counterparts.
- He characterized one of the spliced isoforms of the AMPA receptor subunit gene Gria4 and demonstrated that this isoform was highly expressed in the cerebellum.
- He and his Children’s National colleagues demonstrated that glutamate and GABA regulate oligodendrocyte progenitor cell proliferation and differentiation.
Even the image selected to grace the special issue’s cover continues the theme of continuity and leaving behind a legacy. That image of Purkinje cells was created by a young scientist who works in Gallo’s lab, Aaron Sathyanesan, Ph.D. Gallo began his career working on the cerebellum – a region of the brain important for motor control – and now studies with a team of scientists and clinician-scientists Purkinje cells’ role in locomotor adaptive behavior and how that is disrupted after neonatal brain injury.
“These cells are the main players in cerebellar circuitry,” Gallo says. “It’s a meaningful image because goes back to my roots as a graduate student and is also an image that someone produced in my lab early in his career. It’s very meaningful to me that Aaron agreed to provide this image for the cover of the special issue.”
Children’s National Hospital researchers for the first time have isolated bacterial extracellular vesicles from the blood of healthy donors, a critical step to better understanding the way gut bacteria communicate with the rest of the body via the bloodstream.
For decades, researchers considered circulating bacterial extracellular vesicles as bothersome flotsam to be jettisoned as they sought to tease out how bacteria that reside in the gut whisper messages to the brain.
There is a growing appreciation that extracellular vesicles – particles that cells naturally release – actually facilitate intracellular communication.
“In the past, we thought they were garbage or noise,” says Robert J. Freishtat, M.D., MPH, associate director, Center for Genetic Medicine Research at Children’s National Research Institute. “It turns out what we throw away is not trash.”
Kylie Krohmaly, a graduate student in Dr. Freishtat’s laboratory, has isolated from blood, extracellular vesicles from Escherichia coli and Haemophilus influenzae, common bacteria that colonize the gut, and validated the results via electron microscopy.
“The images are interesting because they look like they have a bit of a halo around them or penumbra,” Krohmaly says.
The team theorizes that the solar eclipse lookalikes contain important signaling proteins and chromatin, DNA from the human host.
“It’s the first time anyone has pulled them out of blood. Detecting them is one thing. Pulling them out is a critical step to understanding the language the microbiome uses as it speaks with its human host,” Dr. Freishtat adds.
Krohmaly’s technique is so promising that the Children’s National team filed a provisional patent.
The Children’s research team has devised a way to gum up the cellular works so that bacteria no longer become antibiotic resistant. Targeted bacteria retain the ability to make antibiotic-resistance RNA, but like a relay runner dropping rather than passing a baton, the bacteria are thwarted from advancing beyond that step. And, because that gene is turned off, the bacteria are newly sensitive to antibiotics – instead of resistant bacteria multiplying like clockwork these bacteria get killed.
“Our plan is to hijack this process in order to turn off antibiotic-resistance genes in bacteria,” Dr. Freishtat says. “Ultimately, if a child who has an ear infection can no longer take amoxicillin, the antibiotic would be given in tandem with the bacteria-derived booster to turn off bacteria’s ability to become antibiotic resistant. This one-two punch could become a novel way of addressing the antibiotic resistance process.”

For months in 2019, Chidiogo Anyigbo, M.D., MPH, had been consumed by the need to learn more and read more about the upcoming 2020 Census. Dr. Anyigbo realized that in asking peers to underscore the importance of the Census with patients and families, the pediatrician hadn’t yet put herself in their shoes.
In late-December 2019, she decided it was time act. She fastened a big yellow pin provided by the DC Mayor’s Census Complete Count Committee that stated “Ask me about the 2020 Census” and that day strove to weave her brief spiel into patients’ clinical visits.
“To my surprise, I was able to have a meaningful exchange in two minutes. I discovered ways to work the topic into conversation while gathering the social history, finishing the physical exam or when providing anticipatory guidance. While some parents met my question with a quizzical look, others were excited to share their positive and negative thoughts about the Census,” Dr. Anyigbo writes in “In the Moment,” the latest installment in a narrative series published by Academic Pediatrics.
Dr. Anyigbo’s research focuses on the relationship between stress, health and social determinants of health. She aims to develop family-centered interventions that can support parents in minimizing the toxic effects of adversity on children. For her, an accurate Census count can play a critical role since the data drives funding for key resources such as health care, schools, grocery stores and nutrition programs that are critical to disrupting the negative effects of poverty and other adverse experiences.
One of her encounters that clinic day was with a mother and her 11-year-old son who had not participated in the 2010 Census. Dr. Anyigbo’s narrative describes how she was able to learn why and discuss with the family the importance of completing this year’s Census.
“The exchange with this mother and son put a face to the statistic of the 1 million children not counted in the 2010 Census,” Dr. Anyigbo writes in the narrative. “Thinking about my patient, I realize that for a majority of his childhood, he was invisible and not counted in the planning and allocation of resources for programs such as Medicaid, Women, Infants and Children (WIC) and funding for Title I schools for his community. His complex housing situation put him, along with children who live with grandparents or households with low English proficiency, at the greatest risk of being missed in the Census.”
Because of her passion for her patients and the community she serves, Dr. Anyigbo plans to bring up the importance of the Census again and again, well beyond the April 1, 2020, official Census Day.
“Few other two-minute investments of my time can have such a profound and lasting impact,” Dr. Anyigbo writes. “My message to families is simple: Please complete the Census, include all children who live in your home, and know that your responses are safe and secure.”
Factoring in the total number of days that extremely preterm infants require supplemental oxygen and tracking this metric for weeks longer than usual improves clinicians’ ability to predict respiratory outcomes according to bronchopulmonary dysplasia (BPD) severity, a research team led by Children’s National Hospital writes in Scientific Reports. What’s more, the researchers defined a brand-new category (level IV) for newborns who receive supplemental oxygen more than 120 days as a reliable way to predict which infants are at the highest risk of returning to the hospital due to respiratory distress after discharge.
About 1 in 10 U.S. infants is born preterm, before 37 weeks gestation, according to the Centers for Disease Control and Prevention. That includes extremely preterm infants who weigh about 1 lb. at birth. These very low birthweight newborns have paper thin skin, frail hearts and lungs that are not yet mature enough to deliver oxygen throughout the body as needed. Thanks to advances in neocritical care, an increasing number of them survive prematurity, and many develop BPD, a chronic lung disease characterized by abnormal development of the lungs and pulmonary vasculature.
“About half of the babies born prematurely will come back to the hospital within the first year of life with a respiratory infection. The key is identifying them and, potentially, preventing complications in this high-risk population,” says Gustavo Nino, M.D., a Children’s National pulmonologist and the study’s lead author.
For decades, the most common way to stratify BPD risk in these vulnerable newborns has been to see if they require supplemental oxygen at 36 weeks corrected gestational age.
“The problem with this classification is it doesn’t take into account the very premature babies who are on oxygen for much longer than other babies. So, we asked the question: Can we continue risk stratification beyond 36 weeks in order to identify a subset of babies who are at much higher risk of complications,” Dr. Nino says.
The longitudinal cohort study enrolled 188 infants born extremely preterm who were admitted to the neonatal intensive care unit (NICU) at Children’s National and tracked their data for at least 12 months after discharge. The team used a multidimensional approach that tracked duration of supplemental oxygen during the newborns’ NICU stay as well as scoring lung imaging as an independent marker of BPD severity. To validate the findings, these U.S.-born newborns were matched with 130 infants who were born preterm and hospitalized at two NICUs located in Bogotá, Colombia.
“Babies who are born very preterm and require oxygen beyond 120 days should have expanded ventilation of the lungs and cardiovascular pulmonary system before going home,” he notes. “We need to identify these newborns and optimize their management before they are discharged.”
And, the babies with level IV BPD risk need a different type of evaluation because the complications they experience – including pulmonary hypertension – place them at the highest risk of developing sleep apnea and severe respiratory infection, especially during the first year of life.
“The earlier we identify them, the better their outcome is likely to be,” Dr. Nino says. “We really need to change the risk stratification so we don’t call them all ‘severe’ and treat them the same when there is a subset of newborns who clearly are at a much higher risk for experiencing respiratory complications after hospital discharge.”
In addition to Dr. Nino, Children’s National study co-authors include Awais Mansoor, Ph.D., staff scientist at the Sheikh Zayed Institute for Pediatric Surgical Innovation (SZI); Geovanny F. Perez, M.D., pediatric pulmonologist; Maria Arroyo, M.D., pulmonologist; Xilei Xu Chen, M.D., postdoctoral fellow; Jered Weinstock, pediatric pulmonary fellow; Kyle Salka, MS, research technician; Mariam Said, M.D., neonatologist, and Marius George Linguraru, DPhil, MA, MSc, SZI principal investigator and senior author. Additional co-authors include Ranniery Acuña-Cordero, Universidad Militar Nueva Granada, Bogotá, Colombia; and Monica P. Sossa-Briceño and Carlos E. Rodríguez-Martínez, both of Universidad Nacional de Colombia.
Funding for research described in this post was provided by the National Institutes of Health (NIH) under award Nos. HL145669, AI130502 and HL141237. In addition, the NIH has awarded Dr. Nino an RO1 grant to continue this research.
As part of the global observance of Rare Disease Day in February, the NCATS and NIH Clinical Center hosted a special event to raise awareness about rare diseases, the people they affect and NIH research collaborations under way to address scientific challenges and advance new treatments.
This year, Children’s National Hospital orthopaedic surgeon Laura Tosi, M.D., took part in an afternoon panel, Nontraditional Approaches to Improving Access for Rare Diseases, where she outlined her work as the faculty chair of the Rare Bone Disease TeleECHO, a virtual meeting that allows care providers and experts to come together via the Zoom platform, discuss diagnosis of specific disorders and present cases for group input.
Dr. Tosi and the Rare Bone Disease Alliance have called Project ECHO Rare Bone Disease a game changer for care of these complex conditions. Rare bone disorders are only about 5% of all birth defects but include 461 skeletal disorders caused by 437 genes – making it difficult for any physician to see enough cases of any one disorder to correctly diagnose and treat it.
“Most doctors are like me, a pediatric orthopaedic surgeon. I need to know a lot of different rare diseases and it’s hard to keep everybody on the cutting edge,” Dr. Tosi says. “Even though we have found the genes for most of the disorders, the phenotypic overlaps, shortage of specialists and the multi-disciplinary needs of so many of the patients add to the challenges.”
So 7 months ago, Dr. Tosi joined together with colleagues at the Rare Bone Disease Alliance and the Osteogenesis Imperfecta Foundation to launch Project ECHO Rare Bone Disease. The now monthly telehealth meeting engages a distinguished faculty of experts from around the world and from across the spectrum of care for these rare bone disorders, including specialists in genetics, endocrinology, orthopaedics and others.
Project ECHO is a specific model for bridging distance and creating a network of professionals, with the goal of leveling the playing field for all by making vital information accessible to everyone, regardless of their location. In healthcare the model transcends traditional “telemedicine,” however. The program, launched from the University of New Mexico, self-describes itself as “telementoring, a guided practice where the participating clinician retains responsibility for the patient” but is able to discuss diagnosis and therapeutic recommendations with a set of esteemed faculty via a regular virtual meeting series.
In the case of the Rare Bone Disease TeleECHO, the ECHO’s faculty decided on two major foci for the curriculum. Half of the content is about how to make the right diagnosis and the other half shares the latest information about specific diseases. The sessions also offer free CME to attendees.
Dr. Tosi says that while finding cases to discuss can sometimes be challenging when it comes to rare bone diseases, she takes responsibility on herself to make sure the content is robust each month. So far the meetings have attracted between 40 and 90 participants per session – a great engagement rate for such a young teleECHO program.
“I believe ECHO advances knowledge of healthcare and democratizes it by offering universal accessibility across the globe,” Tosi notes.
The Rare Bone Disease Alliance, which consists of 12 organizations, experts and patient families working together, is now deciding what’s next for the Rare Bone Disease TeleECHO. They may develop disorder-specific ECHOs, are studying the frequency of the sessions and how best to improve participation for all sessions. The idea is to increase access to this expertise even further, as it could have critical impacts on patients worldwide living with these rare diseases.
In terms of key take-aways from the panel of experts at Rare Disease Day, the hope is that more disease groups might leverage this type of technology to connect people in nontraditional ways. Doing so has the potential to ensure that everyone with a rare disease receives the best support and care possible because their doctors have the knowledge they need when they need it.
Watch more sessions from the NIH’s Rare Disease Day 2020.
“Fires, tornadoes and other natural disasters are outside of our team’s control. But it is within our team’s control to train neonatal intensive care unit (NICU) staff to master this necessary skill,” says Lisa Zell, BSN, a clinical educator at Children’s National Hospital.
Research into how to create a robust emergency evacuation preparedness plan and continually train staff that was led by Zell was lauded by editors of The Journal of Perinatal & Neonatal Nursing. The journal named the study the “best article” for the neonatal section that the prestigious journal published in 2018-19.
“We all hope for the best no matter what the situation, but we also need to extensively plan for the worse,” says Billie Lou Short, M.D., chief of the division of neonatology at Children’s National. “I’m proud that Lisa Zell and co-authors received this much-deserved national recognition on behalf of the nation’s No. 1 NICU.”
Educators worked with a diverse group within Children’s National to design and implement periodic evacuation simulations.
In addition to Zell and Lamia Soghier, M.D., FAAP, CHSE, Children’s National NICU medical unit director, study co-authors include Carmen Blake, BSN; Dawn Brittingham, MSN; and Ann-Marie Brown, MSN.
