Transforming pediatric hip surgery with robotics and 3D imaging

Matthew Oetgen, MD, and the hip pinning robot

“This project is exciting as it targets more precise surgery with improved safety in terms of decreased radiation,” says Matthew Oetgen, MD, division chief of Orthopaedic Surgery and Sports Medicine at Children’s National.

What if surgeons could fix a child’s hip with pinpoint accuracy – using fewer X-rays and cutting-edge robotics? That’s the promise of a new National Institutes of Health funded project combining 3D imaging and robotic technology to improve the treatment of slipped capital femoral epiphysis (SCFE), a condition that affects the hip joint in growing children.

What’s been the hold-up in the field?

Right now, orthopedic surgeons place screws by hand using 2D X-ray images to guide them. To see the screw from different angles, they have to move the X-ray machine around. “The screw must be placed near the center of the femoral head, but not penetrate it,” says Kevin Cleary, PhD, associate director of engineering at the Sheikh Zayed Institute for Pediatric Surgical Innovation (SZI). This process takes time and can increase the amount of radiation the patient receives.

Even though better tools like 3D imaging and surgical robots exist, they aren’t used together in current surgical practice. “Individual procedures have nuances that require their own validated workflows,” says Tyler Salvador, a research engineer at Children’s National Hospital. In other words, each type of surgery is different, and doctors need proven steps before using new technology in the operating room.

How does this work move the field forward?

This project brings together low-dose 3D X-rays from nView with a small surgical robot called Micromate™ to help place screws more precisely during SCFE surgeries. “Our research group has been developing robotics, imaging, and related technologies to improve surgical procedures,” says Dr. Cleary. While these tools exist separately, putting them together in one system focused on bone surgery is new. Tyler Salvador adds, “This will provide a complete solution for precision SCFE implant placement and verification.”

“This project is exciting as it targets more precise surgery with improved safety in terms of decreased radiation,” says Matthew Oetgen, MD, division chief of Orthopaedic Surgery and Sports Medicine at Children’s National. “This is a paradigm-shifting effort that will improve outcomes while improving safety which is the holy grail of translational clinical research. It embodies the goal of the SZI — combining technical expertise with surgical leadership to improve outcomes in pediatric surgery.”

Children’s National leads the way

Children’s National is unique because the Sheikh Zayed Institute combines research and clinical care in one place. “Having the labs right inside the hospital helps us work closely with doctors,” says Salvador.

Together, this work is paving the way for safer, faster and more precise surgeries for children with hip problems. By combining advanced imaging and robotics, the team at Children’s National is helping shape the future of pediatric orthopedic care. In addition to this robotic hip pinning project, the Children’s National team is also behind two additional groundbreaking projects including robotic gallbladder removal and a kidney surgery initiative.

This project has been funded in whole with federal funds from the National Institutes of Health under Contract No. R01EB035559.

Preliminary study points to efficacy of PBMC-based immunotherapy for neuroblastoma

3D illustration of cancer cells

Pediatric solid tumors like neuroblastoma remain a major cause of illness and death, because traditional treatments effective for other tumor types have had only limited success.

A novel immunotherapy approach that involves training autologous T cells derived from peripheral blood mononuclear cells (PBMCs) has shown early signs of safety and efficacy in a small pre-clinical model. The approach, pioneered by researchers within the Sheikh Zayed Institute for Pediatric Surgical Innovation at Children’s National Hospital, may have future implications for the treatment of intractable pediatric solid tumors such as neuroblastoma.

What it means

Pediatric solid tumors like neuroblastoma remain a major cause of illness and death, because traditional treatments effective for other tumor types have had only limited success. There is an urgent need for innovative strategies to effectively target these tumors.

This study presents another approach to cell therapy that collects peripheral blood mononuclear cells from the patient and teaches them to target and eliminate solid tumor cells through exposure to similar tumor cells in a controlled laboratory setting. The cells are then primed to find and attack the solid tumor cells when reintroduced, an approach known as adoptive immunotherapy.

What’s new

The authors note that more well-established modalities such as CAR-T and TCR-T therapies have also made significant advances and demonstrate clinical promise at battling cancers such as neuroblastoma. However, the approach presented in the paper offers early promise of an additional potential strategy, especially in a context “where simplicity, speed and safety are priorities.”

By using small molecule treatments, the authors induce an immunogenic response in neuroblastoma tumor cells, making them more recognizable and attackable by immune cells. Ex vivo training of PBMCs with treated neuroblastoma cells exhibited strong tumor-killing activity.

The authors highlight a few key differences of this approach versus existing adoptive cellular therapies. The method “is technically straightforward, requiring only small tumor samples and peripheral blood mononuclear cells (PBMCs), and avoids the need for the complex genetic engineering intrinsic to CAR-T and TCR-T manufacturing,” the authors write. This method leverages ex vivo tumor cell modification, which may mitigate systemic toxicities. “Additionally, because our approach is not limited to a few surface antigens, it may expand the repertoire of actionable tumor-associated targets.”

Children’s National leads the way

Children’s National is a leader in the development of cell therapies for a wide range of pediatric conditions, including pediatric cancer, HIV/AIDS, sickle cell disease and others.

This research is the latest development in a decade-plus of focused research in adoptive immunotherapy within the Center for Cancer and Immunology Research and the Sheikh Zayed Institute for Pediatric Surgical Innovation.

What’s next

The authors write that there are several critical areas for future research to advance this approach, including a need to understand the specific T cell component and receptors involved in recognizing tumor antigens. They will also need to explore the longevity of the trained T cell response including studies of the memory and persistence of trained PBMCs to ensure lasting anti-tumor effects. Finally, the team will explore the risk of T cell exhaustion, which could reduce the effectiveness of the therapy over time.

Though work remains, the authors note, “Our findings lay the groundwork for developing this approach into a viable therapy for neuroblastoma and possibly other solid tumors as well.”

Leadless pacemakers, subcutaneous defibrillators successfully implanted in pediatric patients

The multi-disciplinary team who implanted the first AVEIR leadless pacemakers at Children’s National.

The multi-disciplinary team who implanted the first AVEIR leadless pacemakers at Children’s National.

Two new devices being used in adults with heart rhythm disorders — atrial and dual chamber leadless pacemakers and extravascular defibrillators — were successfully implanted in pediatric patients for the first time at Children’s National. These devices represent the latest technology in pacing and defibrillating the heart to maintain its rhythm. Though they are smaller in size, have fewer complications and longer battery life than most of the devices currently available for young patients, they have not been available for use in these younger patients until recently.

“For the first time, we’re bringing these devices that are smaller, smarter, less painful and more flexible to children and teenagers who can really benefit from them,” says Elizabeth Sherwin, MD, a pediatric cardiologist and electrophysiologist at Children’s National who led the teams completing these minimally invasive procedures.

The patient benefit

Offering implantation of these devices gives more children and adults with congenital heart disease access to the latest technologies in implantable heart rhythm devices, which may offer unique benefits for these groups.

Abbott AVEIR dual chamber leadless pacemaker is the newest FDA approved leadless pacemaker. It uses electricity to maintain heart rhythm and can be used to pace both the top and bottom chambers of the heart, which is particularly important for pediatric and adult congenital patients. These devices also:

  • Are designed to be removed and replaced after battery runs down, which is ideal for children and young adults who will have multiple replacements over a lifetime.
  • Long battery life, so fewer replacements may be necessary.
  • Can be placed minimally invasively

Dr. Sherwin says that the minimally invasive procedure and the lack of leads on these devices are particularly key for younger people because these factors remove or reduce the risk of complications commonly experienced with pacemakers in children. There is a reduced risk of bleeding, infection, lead movement or fracture, and long-term problems with the veins.  Even better, because they are placed directly in the heart, there are no scars on the chest or visible signs of a pacemaker present.

Medtronic Aurora EV-ICD is an extravascular implantable cardioverter-defibrillator (ICD), which is implanted under the skin (subcutaneous) with a generator on the left chest wall and a lead that goes under the breastbone (sternum). The design includes:

  • A smaller generator.
  • No need to go through chest muscle, leading to less painful implantation and more comfort long term.
  • Emergency heart pacing through the substernal lead – both to try to terminate a fast arrhythmia to avoid need for a shock, and to treat in case the heartbeat is too slow.
  • Longer battery life (projected 11 years).
  • Avoids the need to have leads in the blood vessels, with the many potential complications that go along with transvenous leads.

For both of these newer devices, the patient’s size, weight and medical history will help determine if they are a good candidate.

The big picture

The Electrophysiology team is the first and only pediatric and congenital cardiology team trained to implant AVEIR leadless pacemakers  and the Aurora EV-ICD for eligible individuals in the mid-Atlantic region. Dr. Sherwin, Charles Berul, MD, and Tom (Nak) Choi, MD, are trained to provide these procedures for people in Washington, DC, Virginia and Maryland. For both devices, Children’s National is among only a handful of children’s hospitals in the U.S. with the training and expertise to offer access to these technologies.

“This is a game-changer for kids with rhythm disorders and adults with congenital heart disease,” Dr. Sherwin says. “We are really excited to be among the first to offer these options for patients who need them.”

In the news: Axios’ Future of Health Summit

“Healthcare is moving very fast. And what often happens in adults, also happens in children. Unfortunately, most of the research is directed initially at adults, and then whittles down to children. At Children’s National, we’re trying to turn that around. We’re trying to do research for children that will expand its way up to adults, turning it on its head.”

Anthony Sandler, MD, senior vice president and surgeon-in-chief, Joseph E. Robert Jr. Center for Surgical Care, and director of the Sheikh Zayed Institute for Pediatric Surgical Innovation highlighted the exciting research and innovation happening at Children’s National – including demonstrating a technology, led by Raj Shekhar, PhD, that uses real-time imaging with augmented reality to project live ultrasound visualization of a patient within the surgeon’s field of view. This enhances surgical precision and ultimately supports positive patient outcomes.

This conversation was a part of Axios’ inaugural Future of Health Summit – an event bringing together the top voices in healthcare, policy and technology to explore the biggest challenges and innovations shaping the future of medicine.

Centering the patient and the planet

REI Week began on Monday with a powerful keynote lecture from Lynn R. Goldman, MD, MS, MPH, Michael and Lori Milken dean of the Milken Institute School of Public Health at the George Washington University. In her talk, “Children: Uniquely vulnerable to climate-related threats,” Dr. Goldman underscored the urgent need to protect children from the environmental hazards of a changing climate and to integrate climate science into pediatric care and advocacy.

At mid-morning, Mary-Anne “Annie” Hartley, MD, PhD, MPH, director of the LiGHT Laboratory at École Polytechnique Fédérale de Lausanne, introduced the “MOOVE” platform — Massive Open Online Validation and Evaluation of clinical LLMs. Her talk demonstrated how artificial intelligence, when rigorously validated, has the potential to transform clinical decision-making and global health equity.

Monday’s final keynote, “Zinc and childhood diarrhea,” was presented by Christopher Duggan, MD, MPH, director of the Division of Nutrition at Harvard Medical School. Dr. Duggan highlighted the global health impact of zinc supplementation in reducing childhood mortality — a reminder that simple, evidence-based interventions can save millions of lives.

In that first day, the first poster session of the week showcased projects in adolescent medicine, global health, infectious diseases, oncology and more. The session reflected the full breadth of research taking place across Children’s National.

Ambroise Wonkam, MD, PhD, professor of genetic medicine at Johns Hopkins University, then delivered Tuesday’s Global Health Keynote Lecture, “Harnessing our common African genomes to improve health and equity globally.” His work affirmed that inclusive genomics is key to building a healthier world.

Later, the Global Health Initiative event and GCAF Faculty Seminar encouraged attendees to pursue collaborative opportunities at home and abroad, reflecting the growing global footprint of Children’s National research programs.

Transforming education and care delivery

On Wednesday, Larrie Greenberg, MD, professor emeritus of pediatrics, kicked off the day with a Grand Rounds keynote on educational transformation: “Shouldn’t teachers be more collaborative with their learners?” He followed with a CAPE workshop exploring the effectiveness of case-based learning.

The Nursing Sponsored Keynote Lecture by Vincent Guilamo-Ramos, PhD, MPH, LCSW, ANP-BC, PMHNP-BC, FAAN, explored “Redesigning the U.S. broken health system.” He offered an urgent and inspiring call to reimagine pediatric care by addressing social determinants of health.

In the Jill Joseph Grand Rounds Lecture, Deena J. Chisolm, PhD, director of the Center for Child Health Equity at Nationwide Children’s Hospital, challenged attendees to move beyond dialogue into action in her talk, “Health equity: A scream to a whisper?,” reminding researchers and clinicians that advocacy and equity must be foundational to care.

The day continued with a poster session spotlighting medical education, neonatology, urology and neuroscience, among other fields.

Posters and pathways to progress

Throughout the week, poster sessions highlighted cutting-edge work across dozens of pediatric disciplines. These sessions gave attendees the opportunity to engage directly with investigators and reflect on the shared mission of discovery across multiple disciplines, including:

Global expert consensus defines first framework for building trustworthy AI in health care

Illustration of a brain, stethoscope and computer chip

The guidelines are the first globally acknowledged framework for developing and deploying health care AI applications and gauging whether the information they generate can be trusted or not.

More than 100 international experts in the application of artificial intelligence (AI) in health care published the first set of consensus guidelines that outline criteria for what it means for an AI tool to be considered trustworthy when implemented in health care settings.

The guidelines, published in the journal the BMJ, are the first globally acknowledged framework for developing and deploying health care AI applications and gauging whether the information they generate can be trusted or not.

What this means

Called the FUTURE-AI framework, the consensus guidelines are organized based on six guiding principles:

  • Fairness
  • Universality
  • Traceability
  • Usability
  • Robustness
  • Explainability

The cadre of experts reviewed and agreed upon a set of 30 best practices that fall within the six larger categories. These practices address technical, clinical, socio-ethical and legal aspects of trustworthy AI. The recommendations cover the entire lifecycle of health care AI: design, development and validation, regulation, deployment and monitoring.

The authors encourage researchers and developers to take these recommendations into account in the proof-of-concept phase for AI-driven applications to facilitate future translation to clinical practice.

Why it matters

“Patients, clinicians, health organizations and authorities need to know that information and analysis generated by AI can be trusted, or these tools will never make the leap from theoretical to real world application in a clinical setting,” says Marius George Linguraru, DPhil, MA, MSc, Connor Family Professor for Research and Innovation in the Sheikh Zayed Institute for Surgical Innovation at Children’s National Hospital and co-author of the guidelines. “Bringing so many international and multi-disciplinary perspectives together to outline the characteristics of a trustworthy medical AI application is part of what makes this work unique. It is my hope that finding such broad consensus will shed light on the greater good  AI can bring to clinics and help us avoid problems before they ever impact patients.”

The FUTURE-AI consortium was founded by Karim Lekadir, PhD, ICREA Research Professor at the University of Barcelona in 2021 and now comprises 117 interdisciplinary experts from 50 countries representing all continents, including AI scientists, clinical researchers, biomedical ethicists and social scientists. Over a 2-year period, the consortium established these guiding principles and best practices for trustworthy and deployable AI through an iterative process comprising an in-depth literature review, a modified Delphi survey and online consensus meetings. Dr. Linguraru contributed with a unique perspective on AI for pediatric care and rare diseases.

What’s next

The authors note that, “progressive development and adoption of medical AI tools will lead to new requirements, challenges and opportunities. For some of the recommendations, no clear standard on how these should be addressed yet exists.”

To tackle this uncertainty, they propose FUTURE-AI as a dynamic, living framework. This includes a dedicated website to allow the global community to participate in the FUTURE-AI network. Visitors can provide feedback based on their own experiences and perspectives. The input gathered will allow the consortium to refine the FUTURE-AI guidelines and learn from other voices.

Charging ahead: Researchers develop robotic renal tumor surgery

robotic surgery apparatus

Researchers at Children’s National Hospital are developing supervised autonomous robotic surgery to make expert kidney tumor removal accessible in rural areas, combining robotics, AI and surgeon oversight for safer, more precise outcomes.

Imagine a robot capable of planning and executing the intricate removal of a cancerous kidney tumor — a concept that might sound like science fiction. Yet this groundbreaking work is underway at the Sheikh Zayed Institute (SZI) for Pediatric Surgical Innovation at Children’s National Hospital.

Called Supervised Autonomous Robotic Renal Tumor Surgery (SARRTS), the project aims to prove that a supervised autonomous kidney resection is feasible. Its goal is to enable general surgeons in rural hospitals to oversee robots performing complex resections, democratizing access to specialized surgical care. Backed by a $1 million contract from the Advanced Research Projects Agency for Health (ARPA-H), the initiative represents new opportunities in medical innovation.

“The hope is that, someday, patients will no longer have to travel to major oncology centers to get the best possible surgical outcome when faced with renal tumors,” said Kevin Cleary, PhD, associate director of engineering at SZI. “We hope to combine the precision of robotics with a surgeon’s clinical expertise to create consistently high outcomes.”

The patient benefit

Surgery is a cornerstone of cancer treatment, but access to skilled surgeons remains unevenly distributed nationwide. Autonomous robotic surgery could address this disparity by increasing access to expert-level care, enhancing the precision and consistency of procedures and unlocking new surgical possibilities beyond human surgeons’ capabilities.

Under the initial concept, the SARRTS system will use a combination of CT imaging and 3D mapping from a robot’s RGB-depth camera. While the robot independently plans and executes the incision and tumor resection, the supervising surgeon retains full control, with the ability to approve, modify or halt the procedure at any time — an interplay between human expertise and robotic precision to help ensure safety.

Testing will be conducted on realistic kidney models, called phantoms, which are designed to train and test surgical outcomes. The project aims to validate the feasibility of supervised autonomous tumor resection while advancing technologies that could pave the way for broader applications.

“Robotics and medicine have finally reached a point where we can consider projects requiring this level of complexity,” said Anthony Sandler, MD, senior vice president and surgeon-in-chief at Children’s National and executive director of SZI. By combining autonomous robotics, artificial intelligence and surgical expertise, we can profoundly impact the lives of patients facing life-altering cancer diagnoses.”

Children’s National leads the way

In addition to the kidney surgery initiative, the Children’s National team is pursuing other groundbreaking projects. These include a second ARPA-H contract focused on robotic gallbladder removal and a National Institutes of Health grant to explore robotic hip-pinning, a procedure used to repair fractured hips with pins, screws and plates.

Axel Krieger, PhD, an associate professor of mechanical engineering at Johns Hopkins University, is collaborating closely on the kidney resection and gallbladder projects. The interdisciplinary team believes this state-of-the-art care could be tested and developed within the next decade.

“This particular surgery is complex, and a robot may offer advantages to address difficulties created by patient anatomy and visibility within the surgical field,” said Dr. Sandler. “We can imagine a day – in the not too distant future – when a human and a robotic arm could team up to successfully advance this care.”

This project has been funded in whole with federal funds from ARPA-H under cooperative agreement AY1AX000023.

AI for good: Children’s National wins global competitions for measuring brain tumors

Children's National Hospital's winning team for the Brain Tumor Segmentation-Africa (BraTS-Africa) challenge

Meet the winners (left to right): Syed M. Anwar, Ph.D., M.S., principal investigator at Children’s National; Daniel Capellan Martin, M.Sc., Polytechnic University of Madrid; Abhijeet Parida, data scientist at Children’s National; and Austin Tapp, Ph.D., postdoctoral research fellow at Children’s National.

Using an award-winning artificial intelligence (AI) algorithm developed at Children’s National Hospital, researchers ranked first in the world in the Brain Tumor Segmentation-Africa (BraTS-Africa) challenge for their approach to identifying different parts of deadly gliomas. The details of their innovative method were recently published on arXiv, a curated research-sharing platform.

“Technology can bridge the gap in healthcare between high- and low-resource countries,” said 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). “By tailoring methods we created at our hospital to fit the needs of specific regions, such as sub-Saharan Africa, our research helps improve medical imaging and diagnosis in challenging environments.”

Dr. Linguraru was the program chair of the International Conference on Medical Image Computing and Computer Assisted Intervention (MICCAI) 2024 in Marrakesh, Morocco, the leading global meeting on AI in medical imaging.

Children’s National leads the way

Gliomas are a type of brain tumor with a high death rate and are especially difficult to diagnose in low- and middle-income countries. Given the increased need in Africa, researchers worldwide came together in Morocco to compete over the best way to accurately detect and measure tumors using MRI data and AI.

By applying advanced machine-learning techniques, the researchers adapted tools initially designed for well-resourced settings to work in countries with far fewer.

The study focused on transfer learning, a process in which an AI model is trained in advance on a large number of brain tumor images and then adjusted to work with smaller sets of new data. In this case, the models were adapted to work with local sub-Saharan African data using a strategy to combine different models’ strengths.

When tested, the approach achieved impressive accuracy scores. The Children’s National team, which included a colleague from the Polytechnic University of Madrid, ranked first in the BraTS-Africa 2024 challenge for identifying different parts of gliomas.

“To make the method widely available, the winning algorithm is shared online for others to use and improve upon,” Dr. Linguraru said. “My favorite part of these competitions is how they highlight the way innovation and collaboration can reduce global healthcare inequalities.”

The big picture

Children’s National researchers consistently lead global events using AI and advanced imaging to tackle complex healthcare challenges. In 2023, the team won a global contest to measure pediatric brain tumors at the MICCAI 2023 Conference. This year’s success in the BraTS-Africa challenge builds on this knowledge base and expands its use to adult gliomas.

At the Radiological Society of North America 2024 annual meeting, which drew 50,000 attendees, Zhifan Jiang, Ph.D., a staff scientist in the Precision Medical Imaging Lab at SZI, also won the Cum Laude Award for his scientific poster on applying AI to radiological images to predict severe outcomes for children with brain tumors caused by neurofibromatosis type 1.

“These achievements show how our science is leading the world in using AI for good,” Dr. Linguraru said. “Every day, we’re building on our knowledge of advanced imaging, brain tumors and AI to improve the diagnosis, measurement and treatment of deadly tumors — on a global scale.”

Colorectal surgeons ensure recognition for surgical innovation of Dr. Asa Yancey

Asa Yancey, M.D.

Dr. Asa Yancey’s pioneering operation went unrecognized for over half a century due to discriminatory publishing practices in academic medicine.

A group of international pediatric colorectal surgery leaders called for the renaming of a surgical procedure for Hirschsprung disease after finding evidence that an African American surgeon, Asa Yancey, M.D., had pioneered the procedure 12 years before its’ current namesake, Franco Soave, M.D. Dr. Yancey was not recognized previously due to discriminatory practices in academic medical publishing.

What it means

A literature review published in the Journal of Surgical Research conducted by the American Pediatric Surgical Association Hirschsprung disease interest group, including Marc Levitt, M.D., chief of Colorectal and Pelvic Reconstruction at Children’s National Hospital, identified that Dr. Yancey’s work describing pull-through of normal colon through a cuff of aganglionic colon as a treatment for Hirschsprung disease was published in 1952. The paper by Soave was published in 1962 and from that work, the “Soave” procedure bore his name.

The authors point out that Dr. Yancey’s pioneering operation went unrecognized for over half a century because of the discriminatory segregation in the publishing practices of academic medicine dating back to the 1950s.

Moving the field forward

Dr. Levitt and his colleagues in the interest group suggested active changes to give posthumous credit to Dr. Yancey, including renaming the procedure to the Yancey-Soave pull-through technique.

Together with Dr. Yancey’s family, including his children, three of whom are physicians, the interest group and other surgeons have started using the procedure’s new name in presentations, operative notes, articles and book chapters.

At the end of their literature review recommending the update, the authors wrote, “Posthumous acknowledgment of Yancey was long overdue but signifies improvements in the inclusion of underrepresented groups in academic medicine while simultaneously reminding physicians that there is still much work to be done.”

Rewriting the script for sickle cell disease

More than 100,000 Americans have sickle cell disease, an inherited blood disorder that can cause excruciating pain crises and shorter life expectancies.

Children’s National has one of the largest sickle cell programs in the United States. We are pioneering treatments and provide specialized care to about 1,500 patients each year. We participate in clinical trials to improve outcomes, shorten treatment time, reduce complications and minimize the need for opioids and chemotherapy.

Kendric receives care at Children's National.

Kendric receives care at Children’s National.

In recognition of our clinical and research excellence, Children’s National was one of a few U.S. pediatric hospitals selected to offer two promising new FDA-approved gene therapies.

Hematologist Robert Sheppard Nickel, M.D., leads a study to reduce toxicities in bone marrow transplants. “Years of development led to these curative therapies,” Dr. Nickel says. “I hope in the future we can safely cure more children with sickle cell disease.”

“The future looks promising to revolutionize the lives of our patients and make these therapies accessible worldwide,” says Andrew Campbell, M.D., director of our Comprehensive Sickle Cell Disease Program.

Kendric and Nasir find hope

In May 2024 at Children’s National, 12-year-old Kendric of Clinton, Maryland, became the world’s first patient with sickle cell disease to begin a commercially approved gene therapy that could dramatically reduce or even eliminate his pain. It involved extracting his bone marrow stem cells; genetically modifying them in a specialized lab to reduce the risk of sickling; and then, after chemotherapy, infusing them back into his bloodstream.

Expert, compassionate care empowered Kendric to understand the science behind his treatment and chart a path to recovery. “My care team taught me how to deal with my disease and everything that I need to know for the future,” he says. “They gave me hope that I could be cured.”

Nasir and his care team

Nasir and his care team.

Nasir, age 20, spent his childhood waiting to find a match for a stem cell transplant to address his sickle cell disease. Finally, in 2023, at Children’s National, he found an answer in gene therapy to alter his own cells.

Due to painful episodes and the need for frequent blood transfusions, both Kendric and Nasir missed out on a lot of school, important moments with friends and simply being kids. Now, they can explore a world in which patients like themselves can overcome this disease and reclaim their health.

“I have all of this oxygen and energy that came out of nowhere,” Nasir says. “It’s really a new life. I feel reborn.”

“The network of doctors at Children’s National gave us reassurance and lots of hope,” says Kendric’s mom, Deborah. “They made us feel like family. We are in awe of how quickly things moved and how much compassion they have shown us.”

Radon in school: A hidden worry for eastern Pennsylvania students

Kids sitting at desks in school

Some students may be exposed to nearly twice the annual dose of natural background radiation, estimated by the U.S. Nuclear Regulatory Commission at 3.1 mSv (310 mrem).

A Children’s National Hospital researcher teamed up with a high school student from Bethlehem, Pa., to shed light on radon, a silent health risk that may be present in some schools.

They examined radon levels in five eastern Pennsylvania school districts. The neighborhoods surrounding all 37 public schools had average radon levels exceeding the federal action level, or 4.0 pCi/L. According to their findings, the same could be true of the school buildings.

In a new research letter published in JAMA Network Open, researchers found some students may be exposed to nearly twice the annual dose of natural background radiation, estimated by the U.S. Nuclear Regulatory Commission at 3.1 mSv (310 mrem).

An odorless and invisible gas, radon is the leading cause of lung cancer among nonsmokers and the second overall cause of lung cancer nationwide. Its greatest danger lies in prolonged exposure, a risk amplified in school settings where children and teachers spend extensive hours. The U.S. Environmental Protection Agency (EPA) estimates more than 70,000 classrooms have high short-term radon levels.

“This study highlights the urgent need for radon testing in schools,” said Beth Tarini, M.D., M.S., M.B.A., co-director of the Center for Translational Research at Children’s National and the manuscript’s senior author. “Unchecked exposure to radon in these settings could have significant short- and long-term health effects, particularly for children.”

The EPA has found that approximately 20% of schools nationwide have done some testing, and only . In the Washington, D.C., region, Dr. Tarini says testing is often done:

  • The District of Columbia requires public schools to test for radon and publicize the results. If the results are above the federal limit of >4pCi/L, the schools are required to mitigate the risk.
  • Maryland doesn’t require schools to test for radon, but some schools test. The state’s largest school district — Montgomery County Public Schools — has been testing for radon since the late 1980s and retests facilities every five years.
  • In Virginia, the commonwealth requires public schools to test for radon, make the results public and report the results to the state.

Brian Yang, the study’s first author, called for action in Pennsylvania and regions with known radon risks.

“This research underscores the need to test radon levels in schools and, if necessary, mitigate,” said Yang, a senior at Moravian Academy in Bethlehem, Pa. “Addressing this invisible and under-recognized threat should be a public health priority.”

Nearly 200 biomedical leaders from Washington, D.C., Maryland, and Virginia gathered at the Children’s National Research & Innovation Campus for the 2nd annual Cell & Gene Therapy Symposium. The event showcased groundbreaking developments in rare disease treatments and underscored the importance of regional collaboration.

“By targeting diseases at the cellular level, we are on the cusp of breakthroughs in cell and gene therapy that will transform medicine,” said Catherine Bollard, M.D., M.B.Ch.B., director of the Center for Cancer and Immunology Research (CCIR) at Children’s National Hospital and a host of the symposium. “Progress will accelerate if we build partnerships beyond our own organizations.”

The big picture

Scientists and clinicians have worked for more than two decades to develop cell and gene therapies aimed at treating diseases on a cellular level. The past few years have been particularly promising as investment in science has led to advancements. Children’s National is at the forefront, as one of the first pediatric hospitals in the world to offer commercial gene therapies for sickle cell disease.

Many more treatments for rare diseases are in development at Children’s National and beyond. Leaders at CCIR are actively building collaborations with companies, academic institutions and enterprises across the mid-Atlantic region to accelerate these efforts.

During the symposium, Eugene Hwang, M.D., chief of Oncology at Children’s National, addressed the urgent need for more effective and less toxic treatments for pediatric brain tumors. He highlighted the potential of combining immunotherapies with innovations like low-intensity focused ultrasound, which can open the blood-brain barrier temporarily to improve drug delivery to tumors.

“With collaboration between the lab and clinic, alongside industry partners and even between hospitals, we can finally make strides I haven’t seen in my entire career,” Dr. Hwang said. “It’s an incredibly inspiring time for all of us.”

Why it matters

Experts from organizations as diverse as MaxCyte, ScaleReady, RoosterBio, PSC Biotech, Qiagen, FujiFilm and the Frederick County Office of Economic Development came together for the daylong conversation.

Michael Friedlander, Ph.D., executive director of the Fralin Biomedical Research Institute at Virginia Tech, emphasized the critical role of regional partnerships in fulfilling the potential of these emerging therapies. He pointed to the collaborative research between Children’s National and Virginia Tech on brain tumors, where bioengineers and cancer researchers are working side-by-side to create new treatments.

“We are now able to begin delivering these leading-edge therapies to patients,” Dr. Friedlander said. “For example, those who live in rural settings often have much less access to such frontline medical innovations. By collaborating with Children’s National and gaining access to urban pediatric populations, as well as patients in our more rural area, we can start to bring these therapies to a much broader audience.”

What’s next

Patrick Hanley, Ph.D., chief and director of the Cellular Therapy Program at Children’s National, observed that other regions in the U.S. are uniting to advance scientific discoveries with the backing of government, academia and industry. He hopes to see similar collaboration across the D.C., Maryland, and Virginia area, known as the DMV. Children’s National is leading an initiative called CHARM – the Capital Health and Mid-Atlantic Regenerative Medicine – to bring regional experts together for webinars, networking events and partnership opportunities.

“There’s significant interest in cell and gene therapy worldwide,” said Dr. Hanley, a symposium host. “I see an even greater interest in creating cell and gene therapy hubs. The time is right for our mid-Atlantic region, and I’m excited to see what unfolds in the next five years.”

Ventricular Assist Device (VAD) successfully used as bridge to congenital heart surgery

Illustration of VAD and heart

The team supported R’s heart using a VAD and an innovative implantation technique to increase the likelihood he would tolerate the device well.

A case study published in the Journal of Thoracic and Cardiovascular Surgery Techniques demonstrates a proof of concept that temporary use of a VAD to support a single ventricle heart may give that heart time to grow stronger and allow for corrective and lifesaving procedures under cardiopulmonary bypass instead of heart transplant.

What it means

The cardiac surgery team at Children’s National Hospital was able to offer a young boy’s family a lifesaving surgical option, after they were told elsewhere that their only choice was palliative care.

Baby R was born with a series of complex congenital heart conditions: Heterotaxy syndrome, unbalanced atrioventricular septal defect (AVSD), severe atrioventricular valve regurgitation, reduced ventricular function and obstructed total anomalous pulmonary venous drainage (TAPVD).

That combination of defects left his family facing an unthinkable statistic — there was an up to 90% possibility that R would die before reaching his first birthday.

A set of early interventions, including an initial attempt at a single ventricular correction called a bi-directional cavo-pulmonary shunt (BCPS) failed. His already weak heart was left even weaker than before. He continued to decline.

“We don’t ever want to say, ‘There is nothing we can do for your child,’” says Yves d’Udekem, M.D., Ph.D., chief of cardiac surgery at Children’s National. “Instead, we make the impossible, possible.”

The team decided to support R’s heart using a ventricular assist device (VAD) and an innovative technique during implantation of the VAD to increase the likelihood that he would tolerate the device well. By relieving some of the heart’s workload, they hoped that complicating functional issues might improve enough to allow surgeons to operate again and fix some of the structural conditions to optimize blood flow.

Children’s National leads the way

There is literature showing VAD used in this way in adults with heart failure, but until now it had never been successfully applied as a bridge to surgical intervention in a child with a single functioning ventricle. These assist devices are typically used only as a bridge to heart transplant in children.

This is the first documented case where ventricular assist device implantation resulted in gradual improvement in ventricular function, atrioventricular valve regurgitation, and pulmonary vascular resistance.

The improvements culminated in a major milestone: After 8 weeks of VAD support, at 6 months old, R was weaned off the device and had a successful BCPS, the first of several surgical procedures to make blood flow in his heart effective enough to sustain his organs.

When he was 14 months old, he returned for a successful second procedure along the established single ventricle pathway.

What’s next

R is nearly 3 years old and thriving at home, not in the CICU, as he waits to undergo the Fontan procedure — the final structural surgery for his single ventricle heart.

The knowledge and skill of Children’s National Heart Center turned this formerly hopeless situation into a brighter prognosis by repurposing existing technology to save a life.

In their case study conclusion, the team writes, “The observed improvement in ventricular function and AV valve regurgitation following VAD implantation in this patient is proof of the concept that patients with a failing single-ventricle circulation can be bridged to recovery by temporary VAD support. This concept may open new avenues of treatment.”

Children’s National again ranked among the best in the nation by U.S. News & World Report

2024-25 US News BadgesChildren’s National Hospital in Washington, D.C., was ranked as a top hospital in the nation by the U.S. News & World Report 2024-25 Best Children’s Hospitals annual rankings. This marks the eighth 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.

This year, U.S. News ended ordinal rankings on its Honor Roll. Instead of assigning a numerical rank from 1 to 10, all hospitals on the Honor Roll will be recognized as having attained the highest standards of care in the nation.

In addition, Children’s National tied for #1 pediatric hospital in the Mid-Atlantic region, which includes New York, New Jersey, Delaware, Pennsylvania, the District of Columbia, West Virginia and Virginia. It’s also best in the Mid-Atlantic in Neonatology.

For the fourteenth straight year, Children’s National ranked in 10 specialty services. New this year, U.S. News included behavioral health as a service line in the rankings. Since it’s the first year, there are no ordinal rankings for behavioral health, but the Children’s National program was named one of the top 50 programs in the country.

“In my first year here, I witnessed what makes Children’s National so special — our commitment to collaboration, empowering one another, and charting a bold path forward for pediatric care,” said Michelle Riley-Brown, MHA, FACHE, president and chief executive officer of Children’s National. “I’m proud U.S. News again recognized Children’s National as one of the top in the nation and the highest-ranked pediatric hospital in D.C., Maryland and Virginia. Together, we’ll continue to push the boundaries of care, research and innovation to make a difference for those who matter most — the kids.”

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 nearly two decades, U.S. News has published Best Children’s Hospitals to empower the parents and caregivers of children with complex medical needs,” said Ben Harder, chief of health analysis and managing editor at U.S. News. “Children’s hospitals appearing on the U.S. News Honor Roll have a track record of delivering unparalleled 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 Children’s National specialty services that U.S. News ranked in the top 10 nationally are:

The other four specialties ranked among the top 50 are Behavioral Health, Cardiology and Heart Surgery, Pulmonology and Lung Surgery, and Urology.

In the news: The future of patient care and access

“It is a market failure that we are dealing with – a lack of incentives leading to a stagnation in innovation with respect to small markets, such as pediatrics. Children’s National Hospital and our partners in other children’s hospitals in the country play a critical role in making noise and sending a message that children should not be an afterthought.” 

Hear more from Kolaleh Eskandanian, Ph.D., M.B.A., during her recent appearance at POLITICO. As vice president and chief innovation officer at Children’s National and Alliance for Pediatric Device Innovation principal investigator, Dr. Eskandanian shared her approach to engaging with the Food and Drug Administration (FDA) to advance artificial intelligence (AI) and machine learning technologies for pediatric healthcare. To date, she noted, the FDA has authorized 950 healthcare-related technologies enabled with AI and machine learning.

Innovating improved outcomes with robotic gallbladder removal

Patients want to hear they are “in good hands” when choosing a surgeon. A Children’s National Hospital team is investigating whether those hands could be replaced with an autonomous robotic arm during pediatric cholecystectomy procedures.

“The role of autonomous surgery is at a pivot point,” said Anthony Sandler, M.D., senior vice president and surgeon-in-chief at Children’s National and director of the Sheikh Zayed Institute of Pediatric Surgical Innovation (SZI). “Just as it is with autonomously driving cars, we are testing whether a gallbladder removal can be controlled and managed by a robotic arm, rather than a laparoscopic surgeon. In preclinical models, we are evaluating whether we can take the next step forward. We believe we can, and this research will be proof of concept for autonomous surgery.”

The big picture

The rate of cholecystectomy has been on the rise among pediatric patients for the last two decades. It becomes necessary when the gallbladder becomes full of painful gallstones, often caused by obesity and inherited blood disorders like sickle cell disease. Across the country, 99% of gallbladder removals happen without complications.

Yet Children’s National hopes to develop technologies to boost that number even higher. Working with partners, the hospital has embarked on two contracts with the Advanced Research Projects Agency for Health (ARPA-H): a three-year and a two-year contract, worth $3.5 million each (75N91023C00048 & 75N91023C00053, respectively). The Children’s National team is collaborating on solutions with Optosurgical Chief Executive Officer Yoseph Kim, M.S.E., and Axel Krieger, Ph.D., associate professor of mechanical engineering at Johns Hopkins University.

They are tapping into two areas of expertise: robotic surgery and the development of a novel fluorescent dye that – when paired with advanced imaging – can aid surgeons in seeing bleeds during gallbladder removals.

The project also combines the talents of Dr. Sandler and Children’s National optical engineer Richard Cha, Ph.D., principal investigator at SZI, to explore how to integrate these technologies in the operating room.

“Autonomous gallbladder removal involves the identification of the target tissue – the bile duct, the cystic artery and the gallbladder. Our team’s new 3D imaging techniques will help visualize and work through the surgical steps, by locating each target,” Dr. Cha said. “When this technology and related programming come together, it could mark a significant step forward in pediatric surgery.”

The fine print

Given the gallbladder’s small size and accessible location just beneath the liver, cholecystectomy is most often done laparoscopically, using small cameras and incisions. There are three main steps: ligating – or closing off – the cystic artery, ligating the cystic duct while protecting the common bile duct, and removing the gallbladder. Drs. Sandler and Cha believe outcomes will improve if the expertise and delicacy of a robot are incorporated into the procedure.

“If you’re that one patient out of 100 who has significant bleeding post-operatively or, even worse, you are among the 0.5% of patients who have an injury to the bile duct, the impact on your wellbeing is significant after that surgery,” Dr. Sandler said. “Having that extra security of technology and guidance will be an incredible value-add for any patient undergoing this procedure.”

These projects have been funded in whole with federal funds from ARPA-H, National Institutes of Health, Department of Health and Human Services, under Contract No. 75N91023C00053 and Contract No. 75N91023C00048.
