An editorial in one of the top-ranked pediatric journals — Lancet Child & Adolescent Health — asserts that researchers studying obesity in children and adolescents should stop comparing medication versus bariatric surgery to see which is more effective.

An editorial in one of the top-ranked pediatric journals — Lancet Child & Adolescent Health — asserts that researchers studying obesity in children and adolescents should stop comparing medication versus bariatric surgery to see which is more effective.

Evan Nadler, M.D., director of the Child and Adolescent Weight-loss Surgery Program at Children’s National Hospital, writes that patients don’t want or need the answer to that question. Instead, the two treatment approaches should work together. He cites the field of oncology, where medicine and surgery work hand-in-hand as a comprehensive treatment plan that is individualized for each person’s unique condition.

Why it matters

“The obesity field has long been evaluating isolated interventions. There is a battle between those who favor medical therapy and those who favor surgical therapy,” Nadler writes. “Would it not make more sense for patients if we consider all available options until the desired weight loss is achieved rather than be a staunch advocate of the therapy that we personally like the best?”

According to Nadler, the American Academy of Pediatrics’ 15-year-process to release their first guidelines for treatment of childhood obesity is a consequence of these same silos.

“If medical and surgical oncologists figured out how to work together decades ago, why is it taking so long for practitioners who treat obesity to join forces and use combination therapy for their patients?”

ACC19 attendees from Children's National

ACC.19: A focus on pediatric cardiology

ACC19 attendees from Children's National

Dr. Gerard Martin, center, accepts an award before delivering the 2019 Dan G. McNamara Keynote lecture at ACC.19.

“Innovation meets tradition,” is how many attendees and journalists described the American College of Cardiology’s 68th Scientific Sessions (ACC.19), which took place March 16-18, 2019 in New Orleans, La.

Gerard Martin, M.D., F.A.A.P., F.A.C.C., F.A.H.A., a pediatric cardiologist and the medical director of Global Services at Children’s National, supported this narrative by referencing both themes in his 2019 Dan G. McNamara keynote lecture, entitled “Improved Outcomes in Congenital Heart Disease through Advocacy and Collaboration.” Dr. Martin highlighted advancements in the field of pediatric cardiology that took place over the past 15 years, while touting modern advancements – such as pulse oximetry screenings for critical congenital heart disease – that were a result of physician-led advocacy and collaboration.

Dr. Martin’s message was to continue to invest in research and technology that leads to medical breakthroughs, but to remember the power of partnerships, such as those formed by the National Pediatric Cardiology Quality Improvement Collaborative. These alliances, which generated shared protocols and infrastructure among health systems, improved interstage mortality rates between surgeries for babies born with hypoplastic left heart syndrome.

A dozen cardiologists and clinicians from the Children’s National Heart Institute also participated in CME panel discussions or delivered poster presentations to support future versions of this template, touching on early-stage innovations and multi-institution research collaborations. The themes among Children’s National Heart Institute faculty, presented to a diverse crowd of 12,000-plus professional attendees representing 108 countries, included:

Personalized guidelines:

  • Sarah Clauss, M.D., F.A.C.C., a cardiologist, presented “Unique Pediatric Differences from Adult Cholesterol Guidelines: Lipids and Preventive Cardiology,” before Charles Berul, M.D., division chief of cardiology and co-director of the Children’s National Heart Institute, presented “Unique Pediatric Differences from Adult Guidelines: Arrhythmias in Adults with Congenital Heart Disease,” in a joint symposium with the American Heart Association and the American College of Cardiology.
  • Berul, who specializes in electrophysiology, co-chaired a congenital heart disease pathway session, entitled “Rhythm and Blues: Electrophysiology Progress and Controversies in Congenital Heart Disease,” featuring components of pediatric electrophysiology, including heart block, surgical treatment of arrhythmias and sudden death risk.

Early detection:

  • Anita Krishnan, M.D., associate director of the echocardiography lab, presented “Identifying Socioeconomic and Geographic Barriers to Prenatal Detection of Hypoplastic Left Heart Syndrome and Transposition of the Great Arteries” as a moderated poster in Fetal Cardiology: Quickening Discoveries.
  • Jennifer Romanowicz, M.D., a cardiology fellow, and Russell Cross, M.D., director of cardiac MRI, presented the “Neonatal Supraventricular Tachycardia as a Presentation of Critical Aortic Coarctation” poster in FIT Clinical Decision Making: Congenital Heart Disease 2.
  • Pranava Sinha, M.D., a cardiac surgeon, presented the poster “Neuroprotective Effects of Vitamin D Supplementation in Children with Cyanotic Heart Defects: Insights from a Rodent Hypoxia Model” in Congenital Heart Disease: Therapy 2.

Coordinated care:

  • Ashraf Harahsheh, M.D., F.A.C.C., F.A.A.P., a cardiologist with a focus on hyperlipidemia and preventive cardiology, co-presented an update about BMI quality improvement (Q1) activity from the American College of Cardiology’s Adult Congenital and Pediatric Quality Network – BMI Q1 leadership panel.
  • Niti Dham, M.D., director of the cardio-oncology program, and Deepa Mokshagundam, M.D., cardiology fellow, presented the poster “Cardiac Changes in Pediatric Cancer Survivors” in Heart Failure and Cardiomyopathies: Clinical 3.
  • Nancy Klein, B.S.N., R.N., C.P.N., clinical program coordinator of the Washington Adult Congenital Heart program at Children’s National, presented the poster “Improving Completion of Advanced Directives in Adults with Congenital Heart Disease” in Risks and Rewards in Adult Congenital Heart Disease.

Innovation:

  • Jai Nahar, M.D., a cardiologist, moderated “Future Hub: Augmented Cardiovascular Practitioner: Giving Doctors and Patients a New Voice.” The session focused on technical aspects of artificial intelligence, such as language processing and conversational artificial intelligence, as well as how applications are used in patient-physician interactions.
  • Nahar also participated in a key event on the Heart-to-Heart stage, entitled “Rise of Intelligent Machines: The Potential of Artificial Intelligence in Cardiovascular Care.”

“While I enjoyed the significant representation of Children’s National faculty at the meeting and all of the presentations this year, one research finding that I found particularly compelling was Dr. Krishnan’s poster about geographical disparities in detecting congenital heart disease,” says Dr. Berul. “Her research finds obstetricians providing care to women in the lowest quartile of socioeconomic areas were twice as likely to miss a diagnosis for a critical congenital heart defect during a fetal ultrasound, compared to obstetricians providing care for women in the highest quartiles.”

Dr. Krishnan’s study was the collaborative effort of 21 centers in the United States and Canada, and investigated how socioeconomic and geographic factors affect prenatal detection of hypoplastic left heart syndrome and transposition of the great arteries.

“We studied over 1,800 patients, and chose these diseases because they require early stabilization by a specialized team at a tertiary care center,” says Dr. Krishnan, who led the research in conjunction with the Fetal Heart Society Research Collaborative. “We hope that by understanding what the barriers are, we can reduce disparities in care through education and community-based outreach.”

Elizabeth Estrada

A new type 2 diabetes program leader in a time of change

Elizabeth Estrada

Elizabeth Estrada, M.D., was struck by the increasing number of children with obesity and type 2 diabetes when she finished her fellowship in 1996. That fascination, along with increasingly alarming statistics about the rise in type 2 diabetes in youth over the past 20 years, steered her to a career focused on pediatric diabetes and metabolism that eventually led her to Children’s National Health System, where she will become the director of the type 2 diabetes program this spring.

Coming most recently from the University of North Carolina, where she served as Chief of the Division of Pediatric Endocrinology and Diabetes, Dr. Estrada will work closely with Children’s National Endocrinology Division Chief Andrew Dauber, M.D., and Diabetes Services Director Fran Cogen, M.D., to create a multidisciplinary type 2 diabetes care structure that she has seen success with throughout her career.

“Children with type 2 diabetes have very different needs than children with type 1,” Dr. Estrada explains. “They need more nutrition, more social work, and psychological support.”

Children’s National presents Dr. Estrada with a unique opportunity at a time when the field of care and treatment options for children with type 2 diabetes is expanding. She aims to develop a comprehensive, multidisciplinary program integrating the established Children’s National obesity program with the nationally-ranked endocrinology and diabetes team, which has a strong foundation in providing psychological support to families, which is part of a larger toolkit at Children’s National to help families manage a diabetes diagnosis.

The obesity program at Children’s National emphasizes personalized clinical care and education to prevent and reduce the prevalence of obesity, incorporating multiple aspects of medical and surgical care for obese children and adolescents through the Improving Diet, Energy and Activity for Life (IDEAL) clinic and the bariatric surgery program. The IDEAL clinic helps children with dietary counseling, health education classes, physical activity and weight-management techniques, as well as psychosocial support to help children reach and maintain a healthy weight.

One of the first children’s hospitals to be accredited by the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP®) and the only hospital in the area to be accredited to perform bariatric surgery on adolescents, the bariatric surgery program at Children’s National is directed by Evan Nadler, M.D., who has been safely performing surgeries for nearly 15 years.

The American Diabetes Association (ADA) recently published updates to the “Standards of Medical Care in Diabetes,” which provides research-based practice recommendations for children and adolescents with type 2 diabetes, including metabolic surgery as a treatment recommendation, stating:

The results of weight-loss and lifestyle interventions for obesity in children and adolescents have been disappointing, and no effective and safe pharmacologic intervention is available or approved by the U.S. Food and Drug Administration in youth. Over the last decade, weight-loss surgery has been increasingly performed in adolescents with obesity. Small retrospective analyses and a recent prospective multicenter nonrandomized study suggest that bariatric or metabolic surgery may have benefits in obese adolescents with type 2 diabetes similar to those observed in adults.

The recommendations further stipulate that metabolic surgery should only be considered under certain circumstances, including for those adolescents with T2D who are markedly obsess (BMI > 35 kg/m2) and who have uncontrolled glycemia and/or serious comorbidities despite lifestyle and pharmacologic intervention, and it should only be performed by an experienced surgeon working as part of a well-organized and engaged multidisciplinary team.

Working closely with Dr. Nadler and the obesity team will be a hallmark of Dr. Estrada’s role.

Her goal is to organize a clinic that not only provides clinical care and surgical options, but also includes research and provides medical education and training to medical students, residents and fellows. Dr. Estrada’s own research has focused on insulin resistance, one of the underlying problems in type 2 diabetes.

“There are several clinical trials currently exploring the efficacy and safety of medications for type 2 diabetes in children, something that is incredibly important since Metformin and insulin are the only approved options at this point,” Estrada says. “It is imperative that we bring research to Children’s National as a complement to the existing programs and to continue providing the highest level of care for these patients.”

The Division of Diabetes and Endocrinology works with the National Institutes of Health, conducts independent research and received support from the Washington Nationals Dream Foundation for its diabetes program, the largest pediatric diabetes program in the region, which provides community education and counsels 1,800 pediatric patients each year.
