Marius George Linguraru giving a lecture on AI

Artificial – and accelerated – intelligence: endless applications to expand health equity

In the complex world of pediatric diseases, researchers need access to data to develop clinical trials and the participation of vulnerable patients to develop new devices and therapies. Both are in short supply, given that most children are born healthy, and most severe pediatric diseases are rare.

That creates a dilemma: how do researchers build a foundation to advance new treatments? Enter artificial intelligence (AI).

“AI is the equalizer: accelerated intelligence for sick kids. No other advance on the horizon holds more promise for improving equity and access to pediatric healthcare when diseases are rare and resources are limited,” says Marius George Linguraru, D.Phil., M.A., M.Sc., the Connor Family Professor in Research and Innovation and principal investigator in the Sheikh Zayed Institute for Pediatric Surgical Innovation (SZI). “AI will shrink the distance between patient and provider, allowing our physicians and scientists to provide targeted healthcare for children more efficiently. The possibilities are endless.”

Why we’re excited

By pioneering AI innovation programs at Children’s National Hospital, Dr. Linguraru and the AI experts he leads are ensuring patients and families benefit from a coming wave of technological advances. The team is teaching AI to interpret complex data that could otherwise overwhelm clinicians. Their work will create systems to identify at-risk patients, forecast disease and treatment patterns, and support complex clinical decisions to optimize patient care and hospital resources. Already, the AI team at SZI has developed data-driven tools touching nearly every corner of the hospital:

  • AI for rheumatic heart disease (RHD): In partnership with Children’s National cardiology leaders, including Craig Sable, M.D., the Uganda Heart Institute and Cincinnati Children’s Hospital, the AI team has developed an algorithm that can use low-cost, portable ultrasound imaging to detect RHD in children and young adults, a disease that takes nearly 400,000 lives annually in limited-resource countries. Early testing shows the AI platform has the same accuracy as a cardiologist in detecting RHD, paving the way for earlier treatment with life-saving antibiotics. This year, Children’s National physicians will be in Uganda, screening 200,000 children with local cardiology experts and AI technology.
  • Newborn screening for genetic conditions with mGene: Working with Rare Disease Institute clinicians and Chief of Genetics and Metabolism Debra Regier, M.D., the AI team has built technology to detect rare genetic disorders, using an algorithm and a smartphone camera to identify subtle changes in facial features. Tested on patients from over 30 countries and published in The Lancet Digital Health, the application helps screen children for advanced care when a geneticist may not be within reach. With funding from the National Institutes of Health, Children’s National and its research partners are piloting a newborn screening program in the Democratic Republic of the Congo.
  • Pediatric brain tumors: To improve and personalize the treatment decisions for children with brain tumors, Dr. Linguraru’s team is working with Brain Tumor Institute Director Roger Packer, M.D., the Gilbert Family Distinguished Professor of Neurofibromatosis, on algorithms that can characterize and measure brain tumors with unprecedented precision. The team recently won the International Pediatric Brain Tumor Segmentation Challenge, distinguishing the Children’s National algorithm as among the best in the world.
  • Ultra-low field magnetic resonance imaging (MRI): With a grant from the Bill & Melinda Gates Foundation, the AI team is working alongside Children’s Hospital Los Angeles, King’s College London and the UNITY Consortium to expand global brain imaging capacity. The consortium is helping clinicians in limited-resource countries improve the treatment of neonatal neurological conditions, using AI to boost the quality of ultra-low field MRI and expand access to this portable and more affordable imaging option.
  • Federated learning: Children’s National has collaborated with NVIDIA and other industry leaders to accelerate AI advances through federated learning. Under this approach, institutions share AI models rather than data, allowing them to collaborate without exposing patient information or being constrained by essential data-sharing restrictions. The SZI team was the only pediatric partner invited to join the largest federated learning project of its kind, studying the lungs of COVID-19 patients. Details were published in Nature Medicine.

Children’s National leads the way

Looking ahead, the Children’s National AI team is pursuing a wide range of advances in clinical care. To support patients treated at multiple clinics, they are developing systems to harmonize images from different scanners and protocols, such as MRI machines made by different manufacturers. Similar work is underway to analyze pathology samples from different institutions consistently.

Automation is also making care more efficient. For example, using data from 1 million chest X-rays, the team is collaborating with NVIDIA to develop a conversational digital assistant that will allow physicians to think through 14 possible diagnoses.

Dr. Linguraru says he and his colleagues are galvanized by the jarring statistic that one in three children with a rare disease dies before age 5. While well-implemented AI initiatives can change outcomes, he says the work must be done thoughtfully.

“In the future, patients will be evaluated by human clinicians and machines with extraordinary powers to diagnose illness and determine treatments,” Dr. Linguraru said. “Our team at Children’s National is leading conversations about the future of pediatric healthcare with a focus on safety, resource allocation and basic equity.”

Learn more about our AI initiatives

Innovation leaders at Children’s National Hospital are building a community of AI caregivers through educational and community-building events. At the inaugural Symposium on Artificial Intelligence in 2023 at the Children’s National Research & Innovation Campus, experts from Virginia Tech, JLABS, Food and Drug Administration, Pfizer, Oracle Health, NVIDIA, AWS Health and elsewhere laid out a vision for using data to advance pediatric medicine. The symposium will return on Sept. 6.

Dr. Linguraru is the program chair of MICCAI 2024, the top international meeting on medical image computing and computer-assisted intervention and the preeminent forum for disseminating AI developments in healthcare. The conference is an educational platform for scientists and clinicians dedicated to AI in medical imaging, with a focus on global health equity. It will take place for the first time in Africa on Oct. 6-10.

Inequity complicates care for children with tracheostomies

child with a tracheostomy tube

Study finds healthcare inequities complicate care of children with tracheostomies.

Approximately 4,000 children in the United States annually undergo tracheostomies, a lifesaving procedure for severe respiratory compromise or upper-airway obstruction. While children with tracheostomies are living longer because of technological advances, their caretakers encounter a variety of issues once at-home care begins, as reported in a study published in Qualitative Health Research.

The study identified lingering problems from the lack of equitable access to appropriate support for patient families and caregivers. Jules Sherman, M.F.A., director of the Biodesign Program at Children’s National Innovation Ventures, led the research in collaboration with Kyle L. Bower, Ph.D., a researcher and instructor at The University of Georgia, and Kolaleh Eskandanian, Ph.D., M.B.A., P.M.P., vice president and chief innovation officer at Children’s National.

The big picture

Interview subjects were 11 primary caregivers of children ages 16 months to 11 years who had a tracheostomy and were supported by multiple lifesaving devices at home such as a ventilator, humidifier and other required medical supplies.

Subjects were questioned about influences and relationships they believed impacted the trajectory of care given to children with tracheostomies. Three themes emerged:

  • Insufficient peer support: Caregivers struggled to find groups who shared similar experiences to help them navigate the uncertainty surrounding their child’s medical care, and content on social media peer groups sometimes heightened their sense of worry.
  • Ineffective trach-care training:
    • For families — Caregivers said the trach-care training they received at their respective hospitals did not reflect real-time situations at home, resulting in high levels of anxiety, multiple home emergency situations and routine calls to 911.
    • Home health nurses — Caregivers shared instances of poor decision-making by at-home nurses in emergency situations, lack of communication with primary caregivers and lack of respect for their input.
  • Challenges facing integrated care: The absence of cohesion between medical professionals, durable medical equipment (DME) companies and insurance providers creates many challenges for caregivers. Due to the excessive cost of lifesaving medical devices and negative interactions by caregivers with insurance companies and DMEs, some caregivers reported turning to the black market to purchase needed medical supplies.

Why it matters

In the United States, 60 percent of children with tracheostomies are readmitted to the hospital for tracheostomy-associated respiratory infection within the first six months of the surgery. This study highlights systemic failures and inequities within the healthcare system, beginning at the hospital and following affected families into their homes, indicating that improvements in the support system, training and healthcare coverage are sorely needed.

The need for a better tracheostomy solution was introduced to Children’s National’s Innovation Ventures by two hospital physicians who are otolaryngologists, Habib Zalzal, M.D. and Rahul Shah, M.D., M.B.A. Followed by an initial market study and design by design firm Archimedic, study author, Sherman, continues working with clinicians at Children’s National and engineers at the University of Oregon and University of Maryland to enhance the prototype developed at Children’s National. The device, called as Trach Sense, is designed to detect accidental decannulation and obstruction events, which are leading causes of tracheostomy-related complications.

Caregiver language preference is associated with asthma outcomes

doctor talking to young girl with asthma

A team of researchers found that language barriers can contribute to increased asthma-related healthcare utilization including emergency department (ED) visits, hospitalizations and intensive care unit (ICU) visits.

Asthma is one of the most common chronic pediatric diseases, affecting more than 4 million children and accounting for approximately 24% of pediatric hospitalizations nationwide. Asthma disproportionally impacts historically marginalized racial and ethnic minorities in the United States, with these populations experiencing increased unscheduled asthma-related healthcare utilization and worse asthma outcomes. Families that speak languages other than English can experience increased patient safety events and worse outcomes in other disease processes, but limited data exists on the role of caregiver language preference on asthma morbidity.

The big picture

In a study published in Pediatrics, a team of researchers found that language barriers can contribute to increased asthma-related healthcare utilization including emergency department (ED) visits, hospitalizations and intensive care unit (ICU) visits.

“Families who speak languages other than English can experience significant barriers to quality healthcare from how they navigate a complex healthcare system to how they are able to communicate with their healthcare providers and receive timely care,” said Mickey Emmanuel, M.D., a pediatric emergency medicine fellow at Children’s National Hospital and lead author of the study. “Understanding how caregiver language preference contributes to pediatric asthma outcomes is crucial.”

What’s been the hold up in the field?

Prior research has characterized that caregivers with non-English language preference or NELP were less likely to receive education on asthma disease management and to be given asthma action plans in their preferred language or use asthma action plans. To date, limited data exists on the role of caregiver language preference on asthma utilization.

“Future studies utilizing qualitative and quality improvement methodology that puts the family’s needs at the center are key,” says Dr. Emmanuel. “Efforts to reduce asthma-related ED visits and hospitalizations for families who speak languages other than English must focus on understanding the unique barriers that caregivers face in caring for their children with asthma, and on delivering linguistically competent asthma care in the ambulatory and hospital settings.”

What’s next?

“This work has allowed us to identify that caregiver language preference is an important determinant for asthma outcomes and will hopefully fuel additional research focused on improving care for this population,” says Dr. Emmanuel.

From here, Children’s National will continue to work with notable mentors and leaders in the Language Equity space, with a clear commitment toward improving care for this population of patients.

Additional Children’s National researchers include: Rachel Margolis, Ph.D., Ranjodh Badh, B.A., Nikita Kachroo, A.E.-C., Stephen J. Teach, M.D., MPH,  and Kavita Parikh, M.D., MSHS.

Improving socioeconomic and educational factors may reduce asthma rates

Doctor helping child with asthma inhaler

Researchers believe that the characteristics of a child’s neighborhood may be driving inequities in rates of early childhood asthma.

Asthma is one of the most common, chronic pediatric diseases in the United States, complicated by persistent disparities in care and outcomes. While hospital systems are determined to tackle this issue, researchers believe that the characteristics of a child’s neighborhood may be driving inequities in rates of early childhood asthma.

In a study published in The Journal of Allergy and Clinical Immunology, researchers found that neighborhoods with improved socioeconomic and educational opportunity were more likely to have lower rates of asthma-related emergency department (ED) visits among children younger than five years old in Washington, D.C.

“The Child Opportunity Index (COI) incorporates 29 different measures of social determinants of health into one single measure. Our findings highlight that higher overall opportunity scores of a child’s neighborhood are associated with lower rates of emergency room visits for asthma-related illness,” says Jordan Tyris, M.D., a hospitalist and lead author of the study. “In particular, the socioeconomic and educational measures drove this association. This tells us that improving socioeconomic and educational factors in areas with higher asthma-related ED utilization might help reduce how often children are getting sick from their asthma.”

In this cross-sectional study, researchers examined 3,806 children who were under the age of 5 with physician-diagnosed asthma, who were included in the Washington, D.C., Pediatric Asthma Registry between January 2018 and December 2019. Children in this age group experience disproportionately high rates of asthma. Of the 3,806 children, 2,132 (56%) kids had a collective 5,852 ED encounters, and 821 (22%) of kids had a collective 1,418 hospitalizations.

According to Dr. Tyris, researchers had to work to define cohorts of children under 5 years of age with diagnosed asthma, due to the considerable overlap in early childhood between the clinical presentations of virally induced wheezing and asthma. Ultimately, this presents a barrier to conducting research that exclusively focuses on this young population.

“These findings highlight the importance of considering efforts to improve social, educational and economic-related characteristics of communities as another method to reduce asthma morbidity in early childhood,” said Dr. Tyris.

Patient and doctor demoing Rare-CAP technology

M.D. in your pocket: New platform allows rare disease patients to carry medical advice everywhere

When someone has a rare disease, a trip to the emergency room can be a daunting experience: Patients and their caregivers must share the particulars of their illness or injury, with the added burden of downloading a non-specialist on the details of a rare diagnosis that may change treatment decisions.

Innovators at Children’s National Hospital and Vanderbilt University Medical Center, supported by Takeda, are trying to simplify that experience using a new web-based platform called the Rare Disease Clinical Activity Protocols, or Rare-CAP. This revolutionary collection of medical information allows patients to carry the latest research-based guidance about their rare disorders in their phones, providing a simple QR code that can open a trove of considerations for any medical provider to evaluate as they work through treatment options for someone with an underlying rare disease.

“No one should worry about what happens when they need medical help, especially patients with rare diseases,” said Debra Regier, M.D., division chief of Genetics and Metabolism at Children’s National and Rare-CAP’s lead medical advisor. “We built this new tool because I have watched as my patient-families have wound up in an emergency room — after all, kids get sprains or fractures — but they don’t have the expertise of a rare disease specialist with them. My hope is that they’re going to pull out their phones and access Rare-CAP, which will explain their rare disease to a new provider who can provide more thoughtful and meaningful care.”

The big picture

A rare disease is defined as any disorder that affects less than 200,000 people in the United States. Some 30 million Americans are believed to be living with one of the 7,000 known rare disorders tracked by the National Organization of Rare Diseases (NORD). Led by Dr. Regier, the Rare Disease Institute at Children’s National is one of 40 NORD centers for excellence in the country that provide care, guidance and leadership for the wide array of disorders that make up the rare disease community.

While a key goal of Rare-CAP is to bolster patient self-advocacy, the platform will also allow medical providers to proactively search for protocols on rare diseases when they know they need specialized advice from experts at Children’s National, a network of tertiary care centers and patient organizations.

As a leading values-based, R&D-driven biopharmaceutical company, Takeda has committed $3.85 million to the project to help activate meaningful change and empower a brighter future for rare disease communities, providing a unique understanding of the struggle that patients and caregivers face when they need care.

“Our team, alongside the medical and rare disease community, saw the need for a single portal to collect standardized care protocols, and we are thrilled to see this innovative tool come to life,” said Tom Koutsavlis, M.D., head of U.S. Medical Affairs at Takeda. “People with rare diseases and their caregivers need faster access to authoritative medical information that providers anywhere can act on, this will lead to improving the standard of care, accelerating time to diagnosis and breaking down barriers to increase equitable access.”

The patient benefit

The creators of Rare-CAP imagined its use in a wide range of settings, including emergency rooms, surgical suites, dental offices, urgent care offices and school clinics. The platform will eventually profile thousands of rare diseases and lay out the implications for care, while also creating a dynamic conversation among users who can offer updates based on real-world experience and changes in medical guidance.

“Our patients are unique, and so is this tool,” Dr. Regier said. “As we roll out Rare-CAP, we believe it is just the beginning of the conversation to expand the platform and see its power for the patient and provider grow, with each entry and each new rare disease that’s added to the conversation.”

Children’s National Hospital ranked #5 in the nation on U.S. News & World Report’s Best Children’s Hospitals Honor Roll

U.S. News BadgesChildren’s National Hospital in Washington, D.C., was ranked #5 in the nation on the U.S. News & World Report 2023-24 Best Children’s Hospitals annual rankings. This marks the seventh straight year Children’s National has made the Honor Roll list. The Honor Roll is a distinction awarded to only 10 children’s hospitals nationwide.

For the thirteenth straight year, Children’s National also ranked in all 10 specialty services, with eight specialties ranked in the top 10 nationally. In addition, the hospital was ranked best in the Mid-Atlantic for neonatology, cancer, neurology and neurosurgery.

“Even from a team that is now a fixture on the list of the very best children’s hospitals in the nation, these results are phenomenal,” said Kurt Newman, M.D., president and chief executive officer of Children’s National. “It takes a ton of dedication and sacrifice to provide the best care anywhere and I could not be prouder of the team. Their commitment to excellence is in their DNA and will continue long after I retire as CEO later this month.”

“Congratulations to the entire Children’s National team on these truly incredible results. They leave me further humbled by the opportunity to lead this exceptional organization and contribute to its continued success,” said Michelle Riley-Brown, MHA, FACHE, who becomes the new president and CEO of Children’s National on July 1. “I am deeply committed to fostering a culture of collaboration, empowering our talented teams and charting a bold path forward to provide best in class pediatric care. Our focus will always remain on the kids.”

“I am incredibly proud of Kurt and the entire team. These rankings help families know that when they come to Children’s National, they’re receiving the best care available in the country,” said Horacio Rozanski, chair of the board of directors of Children’s National. “I’m confident that the organization’s next leader, Michelle Riley-Brown, will continue to ensure Children’s National is always a destination for excellent care.”

The annual rankings are the most comprehensive source of quality-related information on U.S. pediatric hospitals and recognizes the nation’s top 50 pediatric hospitals based on a scoring system developed by U.S. News.

“For 17 years, U.S. News has provided information to help parents of sick children and their doctors find the best children’s hospital to treat their illness or condition,” said Ben Harder, chief of health analysis and managing editor at U.S. News. “Children’s hospitals that are on the Honor Roll transcend in providing exceptional specialized care.”

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.

The eight Children’s National specialty services that U.S. News ranked in the top 10 nationally are:

The other two specialties ranked among the top 50 were cardiology and heart surgery, and urology.

William SheehanWilliam Sheehan, M.D., joined Children’s National Hospital in 2017 as a board-certified allergist and immunologist with a passion for helping patients with asthma, allergies, eczema and immunodeficiency. During his fellowship at Children’s Hospital of Boston, he investigated the impact of inner-city and school environments on children’s asthma, and he found reward in helping children breathe easier. Dr. Sheehan will be discussing the impact of the environment on childhood asthma at the upcoming CNH-NIAID Symposium on Promoting Child Health: From Environmental Challenges to Pandemic. He shared with Innovation District an overview of his research and his hope for using biologics to treat asthma.

Q: Could you talk about the research you have been involved in?

A: Since my fellowship, my work has been specifically targeting the interaction between environmental exposures in school and asthma. By intervening in the school environment, we could help dozens of children with asthma. In recent years and here at Children’s National, I have become interested in research regarding using biological medicines to treat inner-city children with asthma. These antibody medications, given by injection, target cells that cause inflammation and are used in children who have severe asthma that is not responding to conventional therapies.

Q: What is new about biologics for treating childhood asthma? How are researchers at Children’s National contributing to the field?

A: The first biologic medicine for treating asthma, called Omalizumab, was approved in 2003. In the last five years, four more biologics have been approved for treating childhood asthma, with more in the pipeline. At Children’s National, we have been trying to identify which biologic therapy is most effective for a particular child with asthma by looking at specific biomarkers. We also are examining new biomarkers that may be beneficial. Specifically, we are looking at the levels of regulatory B cells, an immune cell that acts as a brake to control allergic inflammation.  We have shown that these cells are lacking in children with severe asthma and may make these children better candidates for biologic therapies.

Q: How prevalent are young patients in the asthma population in D.C., and do you believe environmental factors associated with living in a city contribute to the higher incidence of asthma in this population?

A: D.C. is a challenging city for pediatric asthma. Not only is asthma prevalence higher here, but we also see higher rates of severe asthma requiring emergency visits, hospitalizations and even admissions to the Pediatric Intensive Care Unit.

While environmental factors such as pollution, second-hand smoke and exposure to mice and cockroaches can contribute to childhood asthma, I don’t think it’s the sole factor in D.C. There might be multiple factors at play, including social structures that make it difficult for families to access and maintain asthma care and medications. Additionally, there seems to be a genetic component as Black and Hispanic children tend to suffer from worse asthma than white children, regardless of the environment.

Q: What specific research areas or topics interest you for future study?

A: We have made significant progress in controlling asthma with biologics, but prevention is the next frontier. Current studies are focusing on treating vulnerable children at a very young age with the goal of preventing the development of asthma later in childhood. If we can’t prevent asthma, we should strive to achieve asthma “remission” through the use current medications and biologic therapies. The goal would be for individuals to go through their year without any symptoms or exacerbations, essentially living as though they don’t have asthma at all.

A team approach to complex bronchopulmonary dysplasia

“By the time a baby is diagnosed with bronchopulmonary dysplasia, families have already had a long journey with prematurity in the neonatal intensive care unit (NICU),” says Hallie Morris, M.D., neonatologist and lead of the Complex Bronchopulmonary Dysplasia (BPD) Program at Children’s National Hospital. “To be able to have a team that is focused on the holistic health of their child in the context of this diagnosis makes a world of difference to these families.”

The big picture

Some premature infants with BPD experience more severe respiratory disease with comorbidities associated with their underlying disease processes, but also factors related to their lengthened intensive care unit (ICU) stay. This includes delayed development with neurodevelopmental impairment, ICU delirium, pulmonary hypertension, airway disease, gastroesophageal reflux disease, feeding difficulties, retinopathy of prematurity and more.

The Complex BPD Program at Children’s National encompasses a group of specialists dedicated to improving the care of infants with BPD and other chronic lung disease of infancy. BPD places extreme demands on families. Education is a critical component for families and our team works to make sure they are well informed, have realistic expectations and understand their care plan.

What they’re saying

  • “Our program is unique in that it has the ability to follow the patient for several months in the NICU as well as after discharge,” says Maria Arroyo, M.D., pulmonologist and co-lead of the Complex BPD Program at Children’s National. “This includes a subacute facility where some of our NICU patients transfer to for continued respiratory weaning and rehabilitation with parent education and outpatient visits once families are home.”
  • “Since this program was created, we have improved patient care and outcomes with this interdisciplinary approach,” says John Berger, M., medical director for the Pulmonary Hypertension Program at Children’s National. “We expect that with our consistent and personalized care, patients will continue have better overall outcomes, less readmissions and improved neurodevelopmental outcomes.

Therapeutic antibiotics associated with reductions in microbial diversity in CF

person pouring pills from bottle to hand

Researchers found that both insufficient beta-lactam pharmacokinetics (PK) and broad-spectrum antibiotics were associated with a greater decrease in species richness at the end of antibiotic therapy compared to pulmonary exacerbations onset.

There are more than 70,000 children and adults living with cystic fibrosis (CF) worldwide. Those with this progressive disease frequently suffer from recurrent episodes of lung infection and inflammation called pulmonary exacerbations.

In a new observational study led by Andrea Hahn, M.D., infectious diseases specialist at Children’s National Hospital, researchers found that both insufficient beta-lactam pharmacokinetics (PK) and broad-spectrum antibiotics were associated with a greater decrease in species richness at the end of antibiotic therapy compared to pulmonary exacerbations onset.

In prior studies evaluating the association between beta-lactam PK, insufficient beta-lactam PK was associated with reduced short-term decreases in microbial diversity compared to sufficient beta-lactam dosing. In this study researchers found that insufficient beta-lactam PK was associated with a greater short-term decrease in microbial diversity.

Dr. Hahn’s team also found that an increased presence of beta-lactam antibiotic resistance genes was associated with lower microbial diversity and lower lung function.

These studies suggest that community-level antibiotic resistance, rather than the resistance patterns of the most prevalent bacteria identified in cultures, may serve as a useful predictor of lung function recovery in individuals with cystic fibrosis (CF). This finding may aid clinicians in selecting the most effective antibiotics to treat pulmonary exacerbations in CF patients, thus enhancing their clinical outcomes.

Hydroxyurea initiation improves spirometry results in children with sickle cell anemia

boy using spirometer

Hydroxyurea therapy may help preserve lung function over time in children with sickle cell anemia.

Children’s National researchers participated in a recent study suggesting that the use of hydroxyurea (HU) therapy in children with sickle cell anemia (SCA) may help preserve lung function over time.

Sickle cell disease is associated with various pulmonary complications, including reactive airways, acute chest syndrome (ACS), pulmonary fibrosis and pulmonary arterial hypertension, which can lead to increased morbidity and mortality. Lung function tends to decline over time in individuals with SCA, and a more irreversible restrictive pathology develops with age and increasing respiratory complications.

Hydroxyurea is a disease-modifying therapy that has been shown to lower the rates of several complications of SCD, such as ACS and painful vaso-occlusive crises. It also might help lessen the severity of airway hyperreactivity in children.

This study provides evidence that hydroxyurea therapy may have a positive impact on pulmonary function in children with SCA, which could be of interest to doctors treating this patient population. By slowing the decline in lung function, hydroxyurea therapy may help reduce the risk of pulmonary complications and improve the overall health outcomes of children with SCA.

Effect of antibiotics on microorganisms and lung function in children with CF

girl looking at medicine bottle

The study suggests that the use of antibiotics to treat PEx in children with CF may not be as harmful to the airway microbiome as previously believed.

Cystic fibrosis (CF) is a disease that affects many people, especially children. Pulmonary exacerbations (PEx) are common in people with CF and can cause a decline in lung function. These PEx are often treated with antibiotics, but little is known about how antibiotics affect the airway microbiome (the collection of microorganisms in the lungs) of people with CF over time.

Experts from Children’s National Hospital took part in a recent study which looked at how the airway microbiome and lung function of children with CF changed over the course of a year following an initial PEx. The study found that the diversity of the airway microbiome increased over the year despite a decrease in lung function associated with repeated PEx events requiring antibiotic therapy. This suggests that repeated treatment with antibiotics may not have a negative impact on the overall diversity of microorganisms in the lungs.

It is important for pediatricians to understand how antibiotics affect the airway microbiome in children with CF because it can help them make more informed decisions about treatment options. The findings of this study suggest that the use of antibiotics to treat PEx in children with CF may not be as detrimental to the airway microbiome as previously thought. This information can help pediatricians provide better care for children with CF and ultimately improve their overall health outcomes.

New study links T cells and airway muscle in obese children with asthma

asthma inhaler

The study found that T cells from obese children with asthma adhere more to the airway muscle than T cells from lean children with asthma.

Obesity-related asthma is a distinct type of asthma that is increasing among children due to an increase in obesity. It is associated with high disease burden that is not responsive to currently available asthma therapies. Researchers from Children’s National are leading the way with the first study of its kind to show a link between T cells and airway muscle. This unique work represents an important step forward in understanding pediatric obesity-related asthma and has the potential to inform the development of new treatments.

What’s been the hold-up in the field?

Researchers do not understand the mechanisms that underlie obesity-related asthma. This lack of knowledge directly affects the ability to find medications that are effective against this disease.

How does this work move the field forward?

The study found that T cells from obese children with asthma adhere more to the airway muscle than T cells from lean children with asthma. This adhesion of T cells to airway muscle causes the muscle to be more contractile. This is the first study to link immune cells in obese children with asthma with airway-specific changes.

How will this work benefit patients?

The study has identified a mechanism where immune cells react with airway muscle. As part of this, few proteins will be studied further to see if they can be targets for medications specifically for obesity-related asthma.

How is Children’s National leading in this space?

Children’s National is leading in this space by initiating a first of its kind study to show the link between the T cells and airway muscle.

Authors on the study from Children’s National Hospital include: Deepa Rastogi, M.D., M.S., Changsuek Yon, Ph.D., and David A. Thompson.

Autonomic markers of extubation readiness in premature infants

Baby on ventilator

Premature infants often require a breathing tube and mechanical ventilation as a mainstay in their therapy. It can be difficult to predict when these patients are ready to come off the ventilator (extubate).

Premature infants often require a breathing tube and mechanical ventilation as a mainstay in their therapy. It can be difficult to predict when these patients are ready to come off the ventilator (extubate). In a study from Pediatric Research, experts from Children’s National Hospital describe a model to predict the success of extubation using markers of autonomic tone (rest and digest versus fight or flight response). This study was led by Suma Hoffman, M.D., neonatologist and co-authored by Adré J. du Plessis, M.B.Ch.B., M.P.H., division chief of Prenatal Pediatrics Institute, Sarah Schlatterer, M.D., prenatal and neonatal neurologist, and Rathinaswamy B. Govindan, Ph.D.

The team deployed a study of 89 infants less than 28 weeks. Heart rate variability (HRV) metrics 24 hours prior to extubation were compared for those with and without extubation success within 72 hours. Receiver-operating curve analysis was conducted to determine the predictive ability of each metric and a predictive model was created.

Conclusions show that extubation success is associated with HRV. The authors demonstrate an autonomic imbalance with low sympathetic and elevated parasympathetic tone in those who failed. α1, a marker of sympathetic tone, was noted to be the best predictor of extubation success especially when incorporated into a clinical model.

With COVID-19, artificial intelligence performs well to study diseased lungs

lung ct scan

New research shows that artificial intelligence can be rapidly designed to study the lung images of COVID-19 patients.

Artificial intelligence can be rapidly designed to study the lung images of COVID-19 patients, opening the door to the development of platforms that can provide more timely and patient-specific medical interventions during outbreaks, according to research published this month in Medical Image Analysis.

The findings come as part of a global test of AI’s power, called the COVID-19 Lung CT Lesion Segmentation Challenge 2020. More than 2,000 international teams came together to train the power of machine learning and imaging on COVID-19, led by researchers at Children’s National Hospital, AI tech giant NVIDIA and the National Institutes of Health (NIH).

The bottom line

Many of the competing AI platforms were successfully trained to analyze lung lesions in COVID-19 patients and measure acute issues including lung thickening, effusions and other clinical findings. Ten leaders were named in the competition, which ran between November and December 2020. The datasets included patients with a range of ages and disease severity.

Yet work remains before AI could be implemented in a clinical setting. The AI models performed comparably to radiologists when analyzing data similar to what the algorithms had already encountered. However, the AI was less valuable when trained on fresh data from other sources during the testing phase, indicating that systems may need to study larger and more diverse data sets to meet their full potential. This is a challenge with AI that has been noted by others too.

What they’re saying

“These are the first steps in learning how we can quickly and accurately train AI for clinical use,” said Marius George Linguraru, D.Phil., M.A., M.Sc., principal investigator at the Sheikh Zayed Institute for Pediatric Surgical Innovation at Children’s National, who led the Grand Challenge Initiative. “The global interest in COVID-19 gave us a groundbreaking opportunity to address a health crisis, and multidisciplinary teams can now focus that interest and energy on developing better tools and methods.”

Holger Roth, senior applied research scientist at NVIDIA, said the challenge gave researchers around the world a shared platform for developing and evaluating AI algorithms to quickly detect and quantify COVID lesions from lung CT images. “These models help researchers visualize and measure COVID-specific lesions of infected patients and can facilitate timelier and patient-specific medical interventions to better treat COVID,” he said.

Moving the field forward

The organizers see great potential for clinical use. In areas with limited resources, AI could help triage patients, guide the use of therapeutics or provide diagnoses when expensive testing is unavailable. AI-defined standardization in clinical trials could also uniformly measure the effects of the countermeasures used against the disease.

Linguraru and his colleagues recommend more challenges, like the lung segmentation challenge, to develop AI applications in biomedical spaces that can test the functionality of these platforms and harness their potential. Open-source AI algorithms and public curated data, such as those offered through the COVID-19 Lung CT Lesion Segmentation Challenge 2020, are valuable resources for the scientific and clinical communities to work together on advancing healthcare.

“The optimal treatment of COVID-19 and other diseases hinges on the ability of clinicians to understand disease throughout populations – in both adults and children,” Linguraru said. “We are making significant progress with AI, but we must walk before we can run.”

Child using inhaler for asthma

Monoclonal antibody reduces asthma exacerbations in urban youth: Q&A with Stephen Teach, M.D.

Child using inhaler for asthmaNew research found that mepolizumab, a monoclonal antibody, decreased asthma flare-ups by 27% in Black and Hispanic children and adolescents who have a severe form of asthma, are prone to asthma attacks, and live in low-income urban neighborhoods.

Stephen Teach, M.D., principal investigator of the IMPACT DC asthma program and co-author of the NIAID-funded Inner City Asthma Consortium-conducted study, offers insight on the importance of this work and what it means for the future of pediatric asthma care at Children’s National Hospital.

What has been the hold-up in this field and how does this work move the field forward?

Urban, Black, and Hispanic children with asthma continue to suffer a disproportionate share of asthma-related morbidity. These findings show that innovative, phenotype-specific therapies are necessary to address their needs.

The study’s investigators were able to document a significant treatment effect in a particularly at-risk population and demonstrated specific gene pathways that were downregulated by treatment with mepolizumab.

What did you find that excites you about this work?

The exciting part of the Inner-City Asthma Consortium’s work has always been that it not only studies whether or not phenotype-driven interventions improve outcomes in high-risk kids, but how those interventions work from a fundamental mechanistic perspective. Those insights drive the science, and the potential clinical applications, forward in an iterative fashion.

How is Children’s National leading in this space?

Investigators from Children’s National continue to be national leaders in developing and testing innovative interventions to address the national disparities in pediatric asthma care and outcomes.

The study, published in the journal The Lancet was co-authored by William Sheehan, M.D., allergist.

The Division of Pulmonary Medicine at Children’s National has been ranked as one of the top ten programs in the nation by U.S. News & World Report.

Social determinants of health and asthma morbidity in youth

boy using asthma inhaler

Researchers believe these findings can help develop localized interventions that can improve pediatric asthma in affected communities.

In a study published in the journal Pediatrics, researchers from Children’s National Hospital found that census-tract measures of decreased educational attainment and increased violent crime were associated with increased census-tract rates of pediatric asthma morbidity.

“Knowing these adverse measures of social determinants are associated with increased asthma-related emergency department and hospitalization at-risk rates, may be an opportunity to inform community-based interventions to reduce pediatric asthma morbidity,” says Jordan Tyris, a hospitalist and lead author of the study.

Researchers evaluated data from 15,492 children with asthma, ages 2-17, living in Washington, D.C., from January 2018 to December 2019. The team discovered that living in areas with greater violent crime and less educational achievement were associated with higher rates of hospitalizations and emergency department visits for asthma, in comparison to other social determinants.

The study authors suggest that there may be complex reasons behind this data, noting that violent crime can reflect toxic stress, less education can be associated with less knowledge about health and medicine and that children in these communities may be less likely to have primary care doctors. Researchers believe these findings can help develop localized interventions that can improve pediatric asthma in affected communities and that more research is needed on the drivers of asthma related sickness, including toxic stress, structural racism and access to medical care.

Other study authors include Anand Gourishankar, M.D., Nikita Kachroo AE-C, Stephen Teach, M.D., Kavita Parikh, M.D., all of Children’s National Hospital and Maranda C. Ward, Ed.D., MPH, of George Washington School of Medicine and Health Sciences.
