Making healthcare innovation for children a priority

Dr. Kurt Newman in front of the capitol building

Recently, Kurt Newman, M.D., president and CEO of Children’s National Hospital, authored an opinion piece for the popular political website, The Hill. In the article, he called upon stakeholders from across the landscape to address the significant innovation gap in children’s healthcare versus adults.

As Chair of the Board of Trustees of the Children’s Hospital Association,  Dr. Newman knows the importance of raising awareness among policy makers at the federal and state level about the healthcare needs of children. Dr. Newman believes that children’s health should be a national priority that is addressed comprehensively. With years of experience as a pediatric surgeon, he is concerned by the major inequities in the advancements of children’s medical devices and technologies versus those for adults. That’s why Children’s National is working to create collaborations, influence policies and facilitate changes that will accelerate the pace of pediatric healthcare innovation for the benefit of children everywhere. One way that the hospital is tackling this challenge is by developing the Children’s National Research & Innovation Campus, which will be the nation’s first innovation campus focused on pediatric research.

Research & Innovation Campus

Children’s National partners with Virginia Tech

Children’s National Hospital and Virginia Tech create formal partnership that includes the launch of a Virginia Tech biomedical research facility within the new Children’s National Research & Innovation Campus.

Children’s National Hospital and Virginia Tech recently announced a formal partnership that will include the launch of a 12,000-square-foot Virginia Tech biomedical research facility within the new Children’s National Research & Innovation Campus. The campus is an expansion of Children’s National that is located on a nearly 12-acre portion of the former Walter Reed Army Medical Center in Washington, D.C. and is set to open its first phase in December 2020. This new collaboration brings together Virginia Tech, a top tier academic research institution, with Children’s National, a U.S. News and World Report top 10 children’s hospital, on what will be the nation’s first innovation campus focused on pediatric research.

Research & Innovation Campus

“Virginia Tech is an ideal partner to help us deliver on what we promised for the Children’s National Research & Innovation Campus – an ecosystem that enables us to accelerate the translation of potential breakthrough discoveries into new treatments and technologies,” says Kurt Newman, M.D., president and CEO, Children’s National. “Our clinical expertise combined with Virginia Tech’s leadership in engineering and technology, and its growing emphasis on biomedical research, will be a significant advance in developing much needed treatment and cures to save children’s lives.”

Earlier this year, Children’s National announced a collaboration with Johnson & Johnson Innovation LLC to launch JLABS @ Washington, DC at the Research & Innovation Campus. The JLABS @ Washington, DC site will be open to pharmaceutical, medical device, consumer and health technology companies that are aiming to advance the development of new drugs, medical devices, precision diagnostics and health technologies, including applications in pediatrics.

“We are proud to welcome Virginia Tech to our historic Walter Reed campus – a campus that is shaping up to host some of the top minds, talent and innovation incubators in the world,” says Washington, D.C. Mayor Muriel Bowser. “The new Children’s National Research & Innovation Campus will exemplify why D.C. is the capital of inclusive innovation – because we are a city committed to building the public and private partnerships necessary to drive discoveries, create jobs, promote economic growth and keep D.C. at the forefront of innovation and change.”

Faculty from the Children’s National Research Institute and the Fralin Biomedical Research Institute at Virginia Tech Carilion (VTC) have worked together for more than a decade, already resulting in shared research grants, collaborative publications and shared intellectual property. Together, the two institutions will now expand their collaborations to develop new drugs, medical devices, software applications and other novel treatments for cancer, rare diseases and other disorders.

“Joining with Children’s National in the nation’s capital positions Virginia Tech to improve the health and well-being of infants and children around the world,” says Virginia Tech President Tim Sands, Ph.D. “This partnership resonates with our land-grant mission to solve big problems and create new opportunities in Virginia and D.C. through education, technology and research.”

The partnership with Children’s National adds to Virginia Tech’s growing footprint in the Washington D.C. region, which includes plans for a new graduate campus in Alexandria, Va. with a human-centered approach to technological innovation. Sands said the proximity of the two locations – just across the Potomac – will enable researchers to leverage resources, and will also create opportunities with the Virginia Tech campus in Blacksburg, Va. and the Virginia Tech Carilion Health Science and Technology campus in Roanoke, Va.

Carilion Clinic and Children’s National have an existing collaboration for provision of certain specialized pediatric clinical services. The more formalized partnership between Virginia Tech and Children’s National will drive the already strong Virginia Tech-Carilion Clinic partnership, particularly for children’s health initiatives and facilitate collaborations between all three institutions in the pediatric research and clinical service domains.

Children’s National and Virginia Tech will engage in joint faculty recruiting, joint intellectual property, joint training of students and fellows, and collaborative research projects and programs according to Michael Friedlander, Ph.D., Virginia Tech’s vice president for health sciences and technology, and executive director of the Fralin Biomedical Research Institute at VTC.

“The expansion and formalization of our partnership with Children’s National is extremely timely and vital for pediatric research innovation and for translating these innovations into practice to prevent, treat and ultimately cure nervous system cancer in children,” says Friedlander, who has collaborated with Children’s National leaders and researchers for more than 20 years. “Both Virginia Tech and Children’s National have similar values and cultures with a firm commitment to discovery and innovation in the service of society.”

“Brain and other nervous system cancers are among the most common cancers in children (alongside leukemia),” says Friedlander. “With our strength in neurobiology including adult brain cancer research in both humans and companion animals at Virginia Tech and the strength of Children’s National research in pediatric cancer, developmental neuroscience and intellectual disabilities, this is a perfect match.”

The design of the Children’s National Research & Innovation Campus not only makes it conducive for the hospital to strengthen its prestigious partnerships with Virginia Tech and Johnson & Johnson, it also fosters synergies with federal agencies like the Biomedical Advanced Research and Development Authority, which will collaborate with JLABS @ Washington, DC to establish a specialized innovation zone to develop responses to health security threats. As more partners sign on, this convergence of key public and private institutions will accelerate discoveries and bring them to market faster for the benefit of children and adults.

“The Children’s National Research & Innovation Campus pairs an inspirational mission to find new treatments for childhood illness and disease with the ideal environment for early stage companies. I am confident the campus will be a magnet for big ideas and will be an economic boost for Washington DC and the region,” says Jeff Zients, who was appointed chair of the Children’s National Board of Directors effective October 1, 2019. As a CEO and the former director of President Obama’s National Economic Council, Zients says that “When you bring together business, academia, health care and government in the right setting, you create a hotbed for innovation.”

Ranked 7th in National Institutes of Health research funding among pediatric hospitals, Children’s National continues to foster collaborations as it prepares to open its first 158,000-square-foot phase of its Research & Innovation Campus. These key partnerships will enable the hospital to fulfill its mission of keeping children top of mind for healthcare innovation and research while also contributing to Washington D.C.’s thriving innovation economy.

regional pediatric endocrinology meeting

Regional pediatric endocrinologists gather at Children’s National

regional pediatric endocrinology meeting

On Nov. 10, 2019, more than 30 pediatric endocrine physicians and nurse practitioners from Washington, D.C., Maryland and Northern Virginia gathered at Children’s National Hospital to discuss the latest in pediatric endocrinology research.

Organized by Paul Kaplowitz, M.D., Professor Emeritus of Pediatrics, this was the third regional pediatric endocrinology meeting since 2012 and the second held at the hospital. “The meetings are a great opportunity for providers to meet regional colleagues who they may communicate with about patients but rarely see face to face,” explains Dr. Kaplowitz.

The providers spent half a day at Children’s National viewing presentations and connecting with their colleagues. Among the presentations was a talk by new Children’s National faculty member Brynn Marks, M.D., MSHPEd, titled, “Medical Education in Diabetes Technologies.”

The presentation highlighted Dr. Marks’ research on how to best teach providers to make optimal use of the information provided by continuous blood glucose monitoring, as well as how to adjust insulin pump settings based on frequent blood glucose testing.

Another notable presentation was by Richard Kahn, Ph.D., recently retired former chief scientific and medical officer at the American Diabetes Association. Dr. Kahn’s talk was titled “Prediabetes: Is it a meaningful diagnosis?”

“This was an excellent talk whose message was that making a diagnosis of ‘prediabetes’ may not be nearly as helpful as we thought, since most patients tests either revert to normal or remain borderline, and there is no treatment or lifestyle change which greatly reduces progression to type 2 diabetes,” says Dr. Kaplowitz.

$6M gift powers new PKD clinical and research activities

kidneys with cysts on them

PKD is a genetic disorder characterized by clusters of fluid-filled sacs (cysts) multiplying and interfering with the kidneys’ ability to filter waste from the blood.

When Lisa M. Guay-Woodford, M.D., McGehee Joyce Professor of Pediatrics at Children’s National Hospital, considers a brand-new gift, she likens it to 6 million gallons of “rocket fuel” that will power new research to better understand polycystic kidney disease.

Dr. Guay-Woodford received a $5.7 million dollar gift to support PKD clinical and research activities. PKD is a genetic disorder characterized by clusters of fluid-filled sacs (cysts) multiplying and interfering with the kidneys’ ability to filter waste from the blood. The kidneys’ smooth surface transforms to a bumpy texture as the essential organs grow oversized and riddled with cysts.

The extraordinary generosity got its start in an ordinary clinical visit.

Dr. Guay-Woodford saw a young patient in her clinic at Children’s National a few times in 2015. The child’s diagnosis sparked a voyage of discovery for the patient’s extended family and, ultimately, they attended a presentation she gave during a regional meeting about PKD. That led to a telephone conversation and in-person meeting as they invited her to describe “the white space” between what was being done at the time to better understand PKD and what could be done.

“It’s the power of the art and science of medicine. They come to see people like me because of the science. If we can convey to patients and families that who they are and their unique concerns are really important to researchers, that becomes a powerful connection,” she says. “The art plus the science equals hope. That is what these families are looking for: We give people the latest insights about their disease because information is power.”

The infusion of new funding will strengthen the global initiative’s four pillars:

  • Coordinated care for children and families impacted by renal cystic disease. The Inherited and Polycystic Kidney Disease (IPKD) program, launched September 2019, includes a cadre of experts working together as a team in the medical home so that “in a single, one-stop visit, Children’s National can address the myriad concerns they have,” she explains. A multi-disciplinary team that includes nephrologists, hepatologists and endocrinology experts meets weekly to ensure the Center of Excellence provides the highest-caliber patient care. The team includes genetic counselors to empower families with knowledge about genetic risks and testing opportunities. A nurse helps families navigate the maze of who to call about which issue. Psychologists help to ease anxiety. “There is stress. There is fear. There is pain that can be associated with this set of diseases. The good news is we can control their medical issues. The bad news is some children have difficulty coping. Our psychologists help children cope so they can be a child and do the normal things that children do,” she says.
  • Strengthening global databases to capture PKD variations. The team will expand its outreach to other centers located around the world – including Australia, Europe, India and Latin America – caring for patients with both the recessive and dominant forms of polycystic kidney disease, to better understand the variety of ways the disease can manifest in children. We really don’t know a lot about kids with the dominant form of the disease. How hard should we push to control their blood pressure, knowing that could ease symptoms? What are the ramifications of experiencing acute pain compared with chronic pain? How much do these pain flareups interfere with daily life and a child’s sense of self,” she asks. Capturing the nuances of the worldwide experience offers the power of harnessing even more data. And ensuring that teams collect data in a consistent way means each group would have the potential to extract the most useful information from database queries.
  • Filling a ‘desperate need’ for biomarkers. Developing clinical trials for new therapies requires having biomarkers that indicate the disease course. Such biomarkers have been instrumental in personalizing care for patients with other chronic conditions. “We are in desperate need for such biomarkers, and this new funding will underwrite pilot studies to identify and validate these disease markers. The first bite at the apple will leverage our imaging data to identify promising biomarkers,” she says.
  • Genetic mechanisms that trigger kidney disease. About 500,000 people in the U.S. have PKD. In many cases, children inherit a genetic mutation but, often, their genetic mutation develops spontaneously. Dr. Guay-Woodford’s research about the mechanisms that make certain inherited renal disorders lethal, such as autosomal recessive polycystic kidney disease, is recognized around the world. The fourth pillar of the new project provides funding to continue her lab’s research efforts to improve the mechanistic understanding of what triggers PKD.

Kidney disease outcomes differ between severely obese kids vs. adults after bariatric surgery

Marva Moxey-Mims in her office at Children's National.

“We know that bariatric surgery improves markers of kidney health in severely obese adults and adolescents,” says Marva Moxey-Mims, M.D. “This research helps to elucidate possible differences in kidney disease outcomes between children and adults post-surgery.”

Adolescents with Type 2 diabetes experienced more hyperfiltration and earlier attenuation of their elevated urine albumin-to-creatinine ratio (UACR) after gastric bypass surgery compared with adults. This finding contrasts with adolescents or adults who did not have diabetes prior to surgery, according to research presented Nov. 8, 2019, during the American Society of Nephrology’s Kidney Week 2019, the world’s largest gathering of kidney researchers.

“Findings from this work support a recent policy statement by the American Academy of Pediatrics (AAP) that advocates for increasing severely obese youths’ access to bariatric surgery,” says Marva Moxey-Mims, M.D., Chief of the Division of Nephrology at Children’s National Hospital and a study co-author.  “We know that bariatric surgery improves markers of kidney health in severely obese adults and adolescents. This research helps to elucidate possible differences in kidney disease outcomes between children and adults post-surgery.”

According to the AAP, the prevalence of severe obesity in youth aged 12 to 19 has nearly doubled since 1999. Now, 4.5 million U.S. children are affected by severe obesity, defined as having a body mass index ≥35 or ≥120% of the 95th percentile for age and sex.

In a Roux-en-Y gastric bypass, the surgeon staples the stomach to make it smaller, so people eat less. Then, they attach the lower part of the small intestine in a way that bypasses most of the stomach so the body takes in fewer calories.

The multi-institutional study team examined the health effects of such gastric bypass surgeries by comparing 161 adolescents with 396 adults enrolled in related studies. They compared their estimated glomerular filtration rates by serum creatinine and cystatin C. UACR was also compared at various time periods, up till five years after surgery.

Across the board, adolescents had higher UACR – a key marker for chronic kidney disease – than adults. However, for kids who had Type 2 diabetes prior to surgery, the prevalence of elevated UACR levels dip from 29% pre-surgery to 6% one year post-surgery. By contrast, adults who had diabetes prior to surgery and elevated UACR did not see a significant reduction in UACR until five years post-surgery.

While hyperfiltration prevalence was similar in study participants who did not have Type 2 diabetes, adolescents who had Type 2 diabetes prior to surgery had an increased prevalence of hyperfiltration for the duration of the study period.

Financial support for research described in this post was provided by the National Institute of Diabetes and Digestive and Kidney Diseases.

Novel approach to detect fetal growth restriction

doctor checking pregnant woman's belly

Morphometric and textural analyses of magnetic resonance imaging can point out subtle architectural deviations associated with fetal growth restriction during the second half of pregnancy, a first-time finding that has the promise to lead to earlier intervention.

Morphometric and textural analyses of magnetic resonance imaging (MRI) can point out subtle architectural deviations that are associated with fetal growth restriction (FGR) during the second half of pregnancy. The first-time finding hints at the potential to spot otherwise hidden placental woes earlier and intervene in a more timely fashion, a research team led by Children’s National Hospital faculty reports in Pediatric Research.

“We found reduced placental size, as expected, but also determined that the textural metrics are accelerated in FGR when factoring in gestational age, suggesting premature placental aging in FGR,” says Nickie Andescavage, M.D., a neonatologist at Children’s National and the study’s lead author. “While morphometric and textural features can discriminate placental differences between FGR cases with and without Doppler abnormalities, the pattern of affected features differs between these sub-groups. Of note, placental insufficiency with abnormal Doppler findings have significant differences in the signal-intensity metrics, perhaps related to differences of water content within the placenta.”

The placenta, an organ shared by the pregnant woman and the developing fetus, delivers oxygen and nutrients to the developing fetus and ferries away waste products. Placental insufficiency is characterized by a placenta that develops poorly or is damaged, impairing blood flow, and can result in still birth or death shortly after birth. Surviving infants may be born preterm or suffer early brain injury; later in life, they may experience cardiovascular, metabolic or neuropsychiatric problems.

Because there are no available tools to help clinicians identify small but critical changes in placental architecture during pregnancy, placental insufficiency often is found after some damage is already done. Typically, it is discovered when FGR is diagnosed, when a fetus weighs less than 9 of 10 fetuses of the same gestational age.

“There is a growing appreciation for the prenatal origin of some neuropsychiatric disorders that manifest years to decades later. Those nine months of gestation very much define the breath of who we later become as adults,” says Catherine Limperopoulos, Ph.D., director of MRI Research of the Developing Brain at Children’s National and the study’s senior author. “By identifying better biomarkers of fetal distress at an earlier stage in pregnancy and refining our imaging toolkit to detect them, we set the stage to be able to intervene earlier and improve children’s overall outcomes.”

The research team studied 32 healthy pregnancies and compared them with 34 pregnancies complicated by FGR. These women underwent up to two MRIs between 20 weeks to 40 weeks gestation. They also had abdominal circumference, fetal head circumference and fetal femur length measured as well as fetal weight estimated.

In pregnancies complicated by FGR, placentas were smaller, thinner and shorter than uncomplicated pregnancies and had decreased placental volume. Ten of 13 textural and morphometric features that differed between the two groups were associated with absolute birth weight.

“Interestingly, when FGR is diagnosed in the second trimester, placental volume, elongation and thickness are significantly reduced compared with healthy pregnancies, whereas the late-onset of FGR only affects placental volume,” Limperopoulos adds. “We believe with early-onset FGR there is a more significant reduction in the developing placental units that is detected by gross measures of size and shape. By the third trimester, the overall shape of the placenta seems to have been well defined so that primarily volume is affected in late-onset FGR.”

In addition to Dr. Andescavage and Limperopoulos, study co-authors include Sonia Dahdouh, Sayali Yewale, Dorothy Bulas, M.D., chief of the Division of Diagnostic Imaging and Radiology, and Biostatistician, Marni Jacobs, Ph.D., MPH, all of Children’s National; Sara Iqbal, of MedStar Washington Hospital Center; and Ahmet Baschat, of Johns Hopkins Center for Fetal Therapy.

Mihailo Kaplarevic

Extracting actionable research data faster, with fewer hassles

Mihailo Kaplarevic

Mihailo Kaplarevic, Ph.D., the newly minted Chief Research Information Officer at Children’s National Hospital and Bioinformatics Division Chief at Children’s National Research Institute, will provide computational support, advice, informational guidance, expertise in big data and data analyses for researchers and clinicians.

Kaplarevic’s new job is much like the role he played most recently at the National Heart, Lung and Blood Institute (NHLBI), assembling a team of researchers and scientists skilled in computing and statistical analyses to assist as in-house experts for other researchers and scientists.

NHLBI was the first institute within the National Institutes of Health (NIH) family to set up a scientific information office. During his tenure, a half-dozen other NIH institutions followed, setting up the same entity to help bridge the enormous gap between basic and clinical science and everything related to IT.

“There is a difference compared with traditional IT support at Children’s National – which will remain in place and still do the same sort of things they have been doing so far,” he says of The Bear Institute for Health Innovation. “The difference is this office has experience in research because every single one of us was a researcher at a certain point in our career: We are published. We applied for grants. We lived the life of a typical scientist. On top of that, we’re coming from the computational world. That helps us bridge the gaps between research and clinical worlds and IT.”

Ultimately, he aims to foster groundbreaking science by recognizing the potential to enhance research projects by bringing expertise acquired over his career and powerful computing tools to help teams achieve their goals in a less expensive and more efficient way.

“I have lived the life of a typical scientist. I know exactly how painful and frustrating it can be to want to do something quickly and efficiently but be slowed by technological barriers,” he adds.

As just one example, his office will design the high-performance computing cluster for the hospital to help teams extract more useful clinical and research data with fewer headaches.

Right now, the hospital has three independent clinical systems storing patient data; all serve a different purpose. (And there are also a couple of research information systems, also used for different purposes.) Since databases are his expertise, he will be involved in consolidating data resources, finding the best way to infuse the project with the bigger-picture mission – especially for translational science – and creating meaningful, actionable reports.

“It’s not only about running fewer queries,” he explains. “One needs to know how to design the right question. One needs to know how to design that question in a way that the systems could understand. And, once you get the data back, it’s a big set of things that you need to further filter and carefully shape. Only then will you get the essence that has clinical or scientific value. It’s a long process.”

As he was introduced during a Children’s National Research Institute faculty meeting in late-September 2019, Kaplarevic joked that his move away from pure computer science into a health care and clinical research domain was triggered by his parents: “When my mom would introduce me, she would say ‘My son is a doctor, but not the kind of doctor who helps other people.’ ”

Some of that know-how will play out by applying tools and methodology to analyze big data to pluck out the wheat (useful data) from the chaff in an efficient and useful way. On projects that involve leveraging cloud computing for storing massive amounts of data, it could entail analyzing the data wisely to reduce its size when it comes back from the cloud – when the real storage costs come in. “You can save a lot of money by being smart about how you analyze data,” he says.

While he expects his first few months will be spent getting the lay of the land, understanding research project portfolios, key principal investigators and the pediatric hospital’s biggest users in the computational domain, he has ambitious longer-term goals.

“Three years from now, I would like this institution to say that the researchers are feeling confident that their research is not affected by limitations related to computer science in general. I would like this place to become a very attractive environment for up-and-coming researchers as well as for established researchers because we are offering cutting-edge technological efficiencies; we are following the trends; we are a secure place; and we foster science in the best possible way by making computational services accessible, affordable and reliable.”

Lee Beers

Getting to know Lee Beers, M.D., FAAP, future president-elect of AAP

Lee Beers

Lee Savio Beers, M.D., FAAP, Medical Director of Community Health and Advocacy at the Child Health Advocacy Institute (CHAI) at Children’s National Hospital carved out a Monday morning in late-September 2019, as she knew the American Academy of Pediatrics (AAP) would announce the results of its presidential election, first by telephone call, then by an email to all of its members.  Her husband blocked off the morning as well to wait with her for the results.  She soon got the call that she was elected by her peers to become AAP president-elect, beginning Jan. 1, 2020. Dr. Beers will then serve as AAP president in 2021 for a one-year term.

That day swept by in a rush, and then the next day she was back in clinic, caring for her patients, some of them teenagers whom she had taken care of since birth. Seeing children and families she had known for such a long time, some of whom had complex medical needs, was a perfect reminder of what originally motivated Dr. Beers to be considered as a candidate in the election.

“When we all work together – with our colleagues, other professionals, communities and families – we can make a real difference in the lives of children.  So many people have reached out to share their congratulations, and offer their support or help. There is a real sense of collaboration and commitment to child health,” Dr. Beers says.

That sense of excitement ripples through Children’s National.

“Dr. Beers has devoted her career to helping children. She has developed a national advocacy platform for children. I can think of no better selection for the president-elect role of the AAP. She will be of tremendous service to children within AAP national leadership,” says Kurt Newman, M.D., Children’s National Hospital President and CEO.

AAP comprises 67​,000 pediatricians, and its mission is to promote and safeguard the health and well-being of all children – from infancy to adulthood.

The daughter of a nuclear engineer and a schoolteacher, Dr. Beers knew by age 5 that she would become a doctor. Trained as a chemist, she entered the Emory University School of Medicine after graduation. After completing residency at the Naval Medical Center, she became the only pediatrician assigned to the Guantanamo Bay Naval Station.

That assignment to Cuba, occurring so early in her career, turned out to be a defining moment that shapes how she partners with families and other members of the team to provide comprehensive care.

“I was a brand-new physician, straight out of residency, and was the only pediatrician there so I was responsible for the health of all of the kids on the base. I didn’t know it would be this way at the time, but it was formative. It taught me to take a comprehensive public health approach to taking care of kids and their families,” she recalls.

On the isolated base, where she also ran the immunization clinic and the nursery, she quickly learned she had to judiciously use resources and work together as a team.

“It meant that I had to learn how to lead a multi-disciplinary team and think about how our health care systems support or get in the way of good care,” she says.

One common thread that unites her past and present is helping families build resiliency to shrug off adversity and stress.

“The base was a difficult and isolated place for some families and individuals, so I thought a lot about how to support them. One way is finding strong relationships where you are, which was important for patients and families miles away from their support systems. Another way is to find things you could do that were meaningful to you.”

Cuba sits where the Atlantic Ocean, Caribbean Sea and Gulf of Mexico meet. Dr. Beers learned how to scuba dive there – something she never would have done otherwise – finding it restful and restorative to appreciate the underwater beauty.

“I do think these lessons about resilience are universal. There are actually a lot of similarities between the families I take care of now, many of whom are in socioeconomically vulnerable situations, and military families when you think about the level of stress they are exposed to,” she adds.

Back stateside in 2001, Dr. Beers worked as a staff pediatrician at the National Naval Medical Center in Bethesda, Maryland, and Walter Reed Army Medical Center in Washington, D.C. In 2003, Dr. Beers joined Children’s National Hospital as a general pediatrician in the Goldberg Center for Community Pediatric Health. Currently, she oversees the DC Collaborative for Mental Health in Pediatric Primary Care, a public-private coalition that elevates the standards of mental health care for all children, and is Co-Director of the Early Childhood Innovation Network. She received the Academic Pediatric Association’s 2019 Public Policy and Advocacy Award.

As a candidate, Dr. Beers pledged to continue AAP’s advocacy and public policy efforts and to further enhance membership diversity and inclusion. Among her signature issues:

  • Partnering with patients, families, communities, mental health providers and pediatricians to co-design systems to bolster children’s resiliency and to alleviate growing pediatric mental health concerns
  • Tackling physician burnout by supporting pediatricians through office-based education and systems reforms
  • Expanding community-based prevention and treatment

“I am humbled and honored to have the support of my peers in taking on this newest leadership role,” says Dr. Beers. “AAP has been a part of my life since I first became a pediatrician, and my many leadership roles in the DC chapter and national AAP have given me a glimpse of the collective good that pediatricians can accomplish by working together toward common strategic goals.”

AAP isn’t just an integral part of her life, it’s where she met her future husband, Nathaniel Beers, M.D., MPA, FAAP, President of The HSC Health Care System. The couple’s children regularly attended AAP meetings with them when they were young.

Just take a glimpse at Lee Beers’ Twitter news feed. There’s a steady stream of images of her jogging before AAP meetings to amazing sunrises, jogging after AAP meetings to stellar sunsets and always, always, images of the entire family, once collectively costumed as The Incredibles.

“I really do believe that we have to set an example: If we are talking about supporting children and families in our work, we have to set that example in our own lives. That looks different for everyone, but as pediatricians and health professionals, we can model prioritizing our families while still being committed to our work,” she explains.

“Being together in the midst of the craziness is just part of what we do as a family. We travel a lot, and our kids have gone with us to AAP meetings since they were infants. My husband even brought our infant son to a meeting at the mayor’s office when he was on paternity leave. Recognizing that not everyone is in a position to be able to do things like that, it’s important for us to do it – to continue to change the conversation and make it normal to have your family to be part of your whole life, not have a separate work life and a separate family life.”

AlgometRx, which joins JPOD @ Philadelphia, was founded by Julia Finkel, M.D., pediatric anesthesiologist and director of Pain Medicine and Research at Children’s Sheikh Zayed Institute.

AlgometRx and Adipomics, two companies that spun out of innovations discovered at Children’s National Health System, have been selected by Johnson & Johnson Innovation – JLABS to join JPOD @ Philadelphia and JPOD @ Boston, respectively.

JLABS is a global network of no-strings-attached incubators for innovative companies from across the pharmaceutical, medical device, consumer and health technology sectors. Start-up companies are free to pursue their own research priorities independently, with access to state-of-the-art facilities to develop new drugs, medical devices, precision diagnostics and health technologies for people around the world.

Both companies got their start at the Sheikh Zayed Institute for Pediatric Surgical Innovation at Children’s National. The Institute focuses on research and innovation that can improve health for children everywhere.

AlgometRx, which joins JPOD @ Philadelphia, was founded by Julia Finkel, M.D., pediatric anesthesiologist and director of Pain Medicine and Research at Children’s Sheikh Zayed Institute. The AlgometRx device is a first-of-its-kind platform technology that aims to objectively measure pain intensity, type and drug effects in real time by capturing a digital image of a patient’s pupillary light response and applying a series of proprietary algorithms to various characteristics.

AlgometRx is designed to provide an objective pain measurement that aims to help physicians select the correct analgesic class of drug and dosage. By optimizing pain assessment, drug selection and drug management, AlgometRx aims to impact the opioid epidemic and the monitoring and management of Opioid Use Disorder.

Adipomics, which joins JPOD @ Boston, was co-founded by Robert Freishtat, M.D., M.P.H., senior investigator in the Center for Genetic Medicine of the Children’s Research Institute and chief of the Division of Emergency Medicine at Children’s National, and pediatric surgeon Evan P. Nadler, M.D., co-director of the Obesity Program and director of the Bariatric Surgery Program at Children’s National.

Adipomics, which joins JPOD @ Boston, was co-founded by pediatric surgeon Evan P. Nadler, M.D., co-director of the Obesity Program and director of the Bariatric Surgery Program at Children’s National, and Robert Freishtat, M.D., M.P.H., senior investigator in the Center for Genetic Medicine of the Children’s Research Institute and chief of the Division of Emergency Medicine at Children’s National. Adipomics was founded with the aim to address the global epidemic of obesity-related diseases including Type 2 diabetes and cardiovascular diseases. World health experts predict that one billion people worldwide will be obese by 2030.

Drs. Nadler and Freishtat discovered that exosomes released from fat cells (adipocytes) carry genetic material that can mediate various diseases related to obesity. Through their research, they developed a proprietary method that aims to detect how obesity affects an individual patient’s metabolism before the onset of overt disease. Adipomics aims to create the first non-invasive, “anticipatory medicine” diagnostic that detects risk for obesity-related diseases prior to the onset of clinical signs or even biochemical abnormalities. If successful, this predictive methodology would enable treatment much earlier in the disease process, which is likely to improve effectiveness.

A recent news release from Children’s National provides more details on these innovations.

As organizations that share a commitment to improving the pace of healthcare innovation, Children’s National and Johnson & Johnson Innovation – JLABS also recently announced their collaboration to launch JLABS @ Washington, DC,  a 32,000-square foot facility to be located at the new Children’s National Research & Innovation Campus in Washington, D.C. The JLABS @ Washington, DC will have the capacity to house up to 50 pharmaceutical, medical device, consumer and health technology companies that are aiming to advance the development of new drugs, medical devices, precision diagnostics and health technologies, including applications in pediatrics. The campus is located on a 12-acre portion of the former Walter Reed Army Medical Center campus in the nation’s capital and is slated to open in 2020, coinciding with the 150th Anniversary of Children’s National Health System.

Cholesterol plaque in artery

Looking for atherosclerosis’ root cause

Cholesterol plaque in artery

A multi-institutional team led by research faculty at Children’s National in Washington, D.C., finds that extracellular vesicles derived from kids’ fat can play a pivotal role in ratcheting up risk for atherosclerotic cardiovascular disease well before any worrisome symptoms become visible.

According to the Centers for Disease Control and Prevention, about one in five U.S. kids aged 6 to 19 is obese, boosting their risk for a variety of other health problems now and later in life.

One of these is atherosclerosis, a term that translates literally as hardening of the arteries. Atherosclerosis causes blood vessels that carry oxygen-rich blood throughout the body to become inflamed. White blood cells called macrophages settle in the vessel wall, which becomes overloaded with cholesterol. A plaque forms that restricts blood flow. But it remains a mystery how fat cells residing in one place in the body can trigger mayhem in cells and tissues located far away.

Small, lipid-lined sacs called extracellular vesicles (EVs), released by cells into the bloodstream, are likely troublemakers since they enable intercellular communication. Now, a multi-institutional team led by research faculty at Children’s National in Washington, D.C., finds that EVs derived from kids’ fat can play a pivotal role in ratcheting up risk for atherosclerotic cardiovascular disease well before any worrisome symptoms become visible. What’s more, the team showed that EVs found in the body’s fat stores can disrupt disposal of cholesterol in a variety of kids, from lean to obese, the team reports online July 22, 2019, in the Journal of Translational Medicine.

“We found that seven specific small sequences of RNA (microRNA) carried within the extracellular vesicles from human fat tissue impaired the ability of white blood cells called macrophages to eliminate cholesterol,” says Robert J. Freishtat, M.D., MPH, senior scientist at the Center for Genetic Medicine Research at Children’s National and the study’s senior author. “Fat isn’t just tissue. It can be thought of as a metabolic organ capable of communicating with types of cells that predispose someone to develop atherosclerotic cardiovascular disease, the leading cause of death around the world.”

Research scientists and clinicians from Children’s National, the George Washington University, NYU Winthrop Hospital and the National Heart, Lung and Blood Institute collaborated to examine the relationship between the content of EVs and their effect on macrophage behavior. Their collaborative effort builds on previous research that found microRNA derived from fat cells becomes pathologically altered by obesity, a phenomenon reversed by weight-loss surgery.

Because heart disease can have its roots in adolescence, they enrolled 93 kids aged 12 to 19 with a range of body mass indices (BMIs), including the “lean” group, 15 youth whose BMI was lower than 22 and the “obese” group, 78 youths whose BMI was in the 99th percentile for their age. Their median age was 17. Seventy-one were young women. They collected visceral adipose tissue during abdominal surgeries and visited each other’s respective labs to perform the experiments.

“We were surprised to find that EVs could hobble the macrophage cholesterol outflow system in adolescents of any weight,” says Matthew D. Barberio, Ph.D., the study’s lead author, a former Children’s National scientist who now is an assistant professor at the George Washington University’s Milken Institute School of Public Health. “It’s still an open question whether young people who are healthy can tolerate obesity—or whether there are specific differences in fat tissue composition that up kids’ risk for heart disease.”

The team plans to build on the current findings to safeguard kids and adults against future cardiovascular risk.

“This study was a huge multi-disciplinary undertaking,” adds Allison B. Reiss, M.D., of NYU Winthrop Hospital and the study’s corresponding author. “Ultimately, we hope to learn which properties belonging to adipose tissue EVs make them friendly or unfriendly to the heart, and we hope that gaining that knowledge will help us decrease morbidity and mortality from heart disease across the lifespan.”

In addition to Dr. Freishtat, additional study co-authors include Samuel B. Epstein, Madeleine Goldberg, Sarah C. Ferrante, and Evan P. Nadler, M.D., director of the Bariatric Surgery Program, all of Children’s National’s Center for Genetic Medicine Research; Lead Author, Matthew D. Barberio, of Millken Institute School of Public Health at the George Washington University; Lora J. Kasselman, Heather A. Renna, Joshua DeLeon, Iryna Voloshyna, Ashley Barlev, Michael Salama and Allison B. Reiss, all of NYU Winthrop Hospital; and Martin P.

Children’s National ranked No. 6 overall and No. 1 for newborn care by U.S. News

Children’s National in Washington, D.C., is the nation’s No. 6 children’s hospital and, for the third year in a row, its neonatology program is No.1 among all children’s hospitals providing newborn intensive care, according to the U.S. News Best Children’s Hospitals annual rankings for 2019-20.

This is also the third year in a row that Children’s National has been in the top 10 of these national rankings. It is the ninth straight year it has ranked in all 10 specialty services, with five specialty service areas ranked among the top 10.

“I’m proud that our rankings continue to cement our standing as among the best children’s hospitals in the nation,” says Kurt Newman, M.D., President and CEO for Children’s National. “In addition to these service lines, today’s recognition honors countless specialists and support staff who provide unparalleled, multidisciplinary patient care. Quality care is a function of every team member performing their role well, so I credit every member of the Children’s National team for this continued high performance.”

The annual rankings recognize the nation’s top 50 pediatric facilities based on a scoring system developed by U.S. News. The top 10 scorers are awarded a distinction called the Honor Roll.

“The top 10 pediatric centers on this year’s Best Children’s Hospitals Honor Roll deliver outstanding care across a range of specialties and deserve to be nationally recognized,” says Ben Harder, chief of health analysis at U.S. News. “According to our analysis, these Honor Roll hospitals provide state-of-the-art medical expertise to children with rare or complex conditions. Their rankings reflect U.S. News’ assessment of their commitment to providing high-quality, compassionate care to young patients and their families day in and day out.”

The bulk of the score for each specialty is based on quality and outcomes data. The process also includes a survey of relevant specialists across the country, who are asked to list hospitals they believe provide the best care for patients with challenging conditions.

Below are links to the five specialty services that U.S. News ranked in the top 10 nationally:

The other five specialties ranked among the top 50 were cardiology and heart surgery, diabetes and endocrinology, gastroenterology and gastro-intestinal surgery, orthopedics, and urology.

Vittorio Gallo Alpha Omega Alpha Award

Vittorio Gallo, Ph.D., inducted into Alpha Omega Alpha

Vittorio Gallo Alpha Omega Alpha Award

Vittorio Gallo, Ph.D., Chief Research Officer at Children’s National, was inducted into Alpha Omega Alpha (AΩA), a national medical honor society that since 1902 has recognized excellence, leadership and research in the medical profession.

“I think it’s great to receive this recognition. I was very excited and surprised,” Gallo says of being nominated to join the honor society.

“Traditionally AΩA membership is based on professionalism, academic and clinical excellence, research, and community service – all in the name of ‘being worthy to serve the suffering,’ which is what the Greek letters AΩA stand for,” says Panagiotis Kratimenos, M.D., Ph.D., an ΑΩΑ member and attending neonatologist at Children’s National who conducts neuroscience research under Gallo’s mentorship. Dr. Kratimenos nominated his mentor for induction.

“Being his mentee, I thought Gallo was an excellent choice for AΩΑ faculty member,” Dr. Kratimenos says. “He is an outstanding scientist, an excellent mentor and his research is focused on improving the quality of life of children with brain injury and developmental disabilities – so he serves the suffering. He also has mentored numerous physicians over the course of his career.”

Gallo’s formal induction occurred in late May 2019, just prior to the medical school graduation at the George Washington University School of Medicine & Health Sciences (GWSMHS) and was strongly supported by Jeffrey S. Akman, Vice President for Health Affairs and Dean of the university’s medical school.

“I’ve been part of Children’s National and in the medical field for almost 18 years. That’s what I’m passionate about: being able to enhance translational research in a clinical environment,” Gallo says. “In a way, this recognition from the medical field is a perfect match for what I do. As Chief Research Officer at Children’s National, I am charged with continuing to expand our research program in one of the top U.S. children’s hospitals. And, as Associate Dean for Child Health Research at GWSMHS, I enhance research collaboration between the two institutions.”

Improving glycemic control in diabetic children

A 10-week pilot study at Children’s National Health System integrated weekly caregiver coaching, personalized glucose monitoring and incentives into standard treatment for 25 pediatric patients with type 1 diabetes, lowering A1c by .5%

The life of a type 1 diabetes patient – taking daily insulin shots or wearing an insulin pump, monitoring blood sugar, prioritizing healthful food choices and fitting in daily exercise – can be challenging at age 5 or 15, especially as holidays, field trips and sleepovers can disrupt diabetes care routines, creating challenges with compliance. This is why endocrinologists from Children’s National Health System experimented with using health coaches over a 10-week period to help families navigate care for children with type 1 diabetes.

By assembling a team of diabetes educators, dietitians, social workers, psychologists and health care providers, Fran Cogen, M.D., C.D.E., director of diabetes care at Children’s National, helped pediatric patients with type 1 diabetes manage their glycemic status, or blood-sugar control.

On Saturday, June 8, 2019, Dr. Cogen will share results of the pilot program as poster 1260-P, entitled “A Clinical Care Improvement Pilot Program: Individualized Health Coaching and Use of Incentives for Youth with Type 1 Diabetes and their Caregivers,” at the American Diabetes Association’s 79th Scientific Sessions, which takes place June 7-11 at the Moscone Center in San Francisco.

Dr. Cogen’s study was offered at no cost to caregivers of 179 patients at Children’s National seeking treatment for type 1 diabetes. The pilot program included two components: 1) Weekly phone calls or emails from a health coach to a caregiver with personalized insulin adjustments, based on patient blood sugars submitted through continuous glucose monitoring apps; and 2) Incentives for patients to participate in the program and reach health targets.

Twenty-five participants, ages 4-18, with a mean age of 11.6 and A1c ranges between 8.6 – 10% joined the study. The average A1c was 9.4% at the beginning of the program and dropped by an average of .5% at the end of the trial. Twenty of the 25 participants, 80%, improved A1c levels by .5%. Seventeen participants, 68%, improved A1c levels by more than .5%, while seven participants, 28%, improved A1c levels by more than 1%.

“Chronic disease is like a marathon,” says Dr. Cogen. “You need to have constant reinforcement and coaching to get people to do their best. Sometimes what drives people is to have people on the other end say, ‘Keep it up, you’re doing a good job, keep sending us information so that we can make changes to improve your child’s blood sugar management,’ which gives these new apps and continuous glucose monitoring devices a human touch.”

Instead of waiting three months between appointments to talk about ways a family can make changes to support a child’s insulin control and function, caregivers received feedback from coaches each week. Health coaches benefitted, too: They reported feeling greater empathy for patients, while becoming more engaged in personalizing care plans.

Families who participated received a gift card to a local grocery store, supporting a child’s dietary goals. Children who participated were also entered into an iPad raffle. Improvements in A1c levels generated extra raffle tickets per child, which motivated participants, especially teens.

“These incentives are helpful in order to get kids engaged in their health and in an immediate way,” says Dr. Cogen. “Teenagers aren’t always interested in long-term health outcomes, but they are interested in what’s happening right now. Fluctuating blood sugars can cause depression and problems with learning, while increasing risk for future complications, including eye problems, kidney problems and circulation problems. As health care providers, we know the choices children make today can influence their future health outcomes, which is why we designed this study.”

Moving forward, Dr. Cogen and the endocrinologists at Children’s National would like to study the impact of using this model over several months, especially for high-risk patients, while  asynchronously targeting information to drive behavior change – accommodating the needs of families, while delivering dose-specific recommendations from health care providers.

Dr. Cogen adds, “We’re moving away from office-centric research models and creating interventions where they matter: at home and with families in real time.”

Detecting early signs of type 2 diabetes through microRNA

Robert J. Freishtat working in the lab

Obesity is a major risk factor for insulin resistance and type 2 diabetes. Now researchers understand the pathogenesis better among teens with mid-level obesity, thanks to clues released from circulating adipocyte-derived exosomes.

Researchers know that exosomes, tiny nanoparticles released from fat cells, travel through the bloodstream and body, regulating a variety of processes, from growth and development to metabolism. The exosomes are important in lean, healthy individuals in maintaining homeostasis, but when fat gets ‘sick’ – the most common reason for this is too much weight gain – it can change its phenotype, becoming inflammatory, and disrupts how our organs function, from how our skeletal muscle and liver metabolize sugar to how our blood vessels process cholesterol.

Robert J. Freishtat, M.D., M.P.H., the chief of emergency medicine at Children’s National Health System and a professor of precision medicine and genomics at the George Washington University School of Medicine and Health Sciences, and Sheela N. Magge M.D., M.S.C.E., who is now the director of pediatric endocrinology and an associate professor of medicine at the Johns Hopkins School of Medicine, were curious about what this process looked like in teens who fell in the mid-range of obesity.

Obesity is a major risk factor for insulin resistance and type 2 diabetes, but Dr. Freishtat and Dr. Magge wanted to know: Why do some teens with obesity develop type 2 diabetes over others? Why are some teens in this mid-range of obesity metabolically healthy while others have metabolic syndrome? Can fat in obese people become sick and drive disease?

To test this, Dr. Freishtat and Dr. Magge worked with 55 obese adolescents, ages 12 to 17, as part of a study at Children’s National. The participants – 32 obese normoglycemic youth and 23 obese hyperglycemic youth – were similar in age, sex, race, pubertal stage, body mass index and overall fat mass. The distinguishing factor: The hyperglycemic study participants, the teens with elevated blood sugar, differed in where they stored fat. They had extra visceral fat (or adipose tissue) storage, the type of fat that surrounds the liver, pancreas and intestines, a known risk factor for type 2 diabetes.

Dr. Magge and Dr. Freishtat predicted that circulating exosomes from the teens with elevated blood sugar are enriched for microRNAs targeting carbohydrate metabolism.

They used three tests to examine study participants’ metabolism, body composition and circulating exosomes. The first test, an oral glucose tolerance test, measures how efficiently the body metabolizes sugar; the second test is the whole body DXA, or dual-energy x-ray absorptiometry, which analyzes body composition, including lean tissue, fat mass and bone mineral density; and the third test, the serum adipocyte-derived exosomal microRNA assays, is an analysis of circulating fat signals in the bloodstream.

They found that teens with elevated blood sugar and increased visceral fat had different circulating adipocyte-derived exosomes. These study participants’ exosomes were enriched for 14 microRNAs, targeting 1,304 mRNAs and corresponding to 179 canonical pathways – many of which are directly associated with carbohydrate metabolism and visceral fat.

Dr. Magge will present this research, entitled “Changes in Adipocyte-Derived Exosomal MicroRNAs May Play a Role in the Progression from Obese Normoglycemia to Hyperglycemia/Diabetes,” as an oral abstract at the American Diabetes Association’s 79th Scientific Sessions on Saturday, June 8.

Dr. Freishtat envisions having this information will be especially helpful for a patient in a mid-range of obesity. Exosomes primarily consist of small non-coding RNAs. In the current study, the altered RNAs affect P13K/AKT and STAT3 signaling, vital pathways for metabolic and immune function.

“Instead of waiting until someone has the biochemical changes associated with type 2 diabetes, such as hyperglycemia, hyperlipidemia and insulin resistance, we’re hoping physicians will use this information to work with patients earlier,” says Dr. Freishtat. “Through earlier detection, clinicians can intervene when fat shows sign of illness, as opposed to when the overt disease has occurred. This could be intervening with diet and lifestyle for an obese individual or intervening with medication earlier. The goal is to work with children and teens when their system is more plastic and responds better to intervention.”

As this research evolves, Dr. Freishtat continues to look at the intergenerational effects of circulating adipocyte-derived exosomes. Through ongoing NIH-funded research in India, he finds these exosomes, similar in size to lipoproteins, can travel across the placenta, affecting development of the fetus in utero.

“What we’re finding in our initial work is that these exosomes, or ‘sick’ fat, cross the placenta and affect fetal development,” Dr. Freishtat says. “Some of the things that we’re seeing are a change in body composition of the fetus to a more adipose phenotype. Some of our work in cell cultures shows changes in stem cell function and differentiation, but what’s even more interesting to us is that if the fetus is a female sex that means her ovaries are developing while she’s in utero, which means a mother’s adipocyte-derived exosomes could theoretically be affecting her grandchild’s phenotype – influencing the health of three generations.”

While this research is underway, Dr. Freishtat is working with JPOD @ Boston, co-located with the Cambridge Innovation Center in Cambridge, Massachusetts, to develop a test to provide analyses of adipocyte-derived exosomal microRNAs.

“It’s important for families to know that these studies are designed to help researchers and doctors better understand the development of disease in its earliest stages, but there’s no need for patients to wait for the completion of our studies,” says Dr. Freishtat. “Reaching and maintaining a healthy body weight and exercising are important things teens and families can do today to reduce their risk for obesity and diabetes.”

Cognitive function does not predict weight-loss outcome for adolescents

child measuring his stomach

Though young people with intellectual disabilities or cognitive impairment have greater rates of obesity and other comorbidities that impact their health and well-being, primary care providers are often reluctant to discuss or refer these patients for weight-loss surgery due to concerns about their ability to assent to both the surgery and the ongoing diet and lifestyle changes after surgery.

However, a study in Pediatrics authored by psychologists at Children’s National Health System finds that these young people, including those with Down syndrome, have similar weight-loss trajectories to those with typical cognitive function after bariatric surgery. The study is the first to look at post-surgical outcomes for this subgroup of adolescent bariatric surgery patients.

“It’s challenging to ensure that an adolescent who is cognitively impaired understands what it means to undergo a surgical procedure like bariatric surgery, but we do find ways to ensure assent whenever possible, and make sure the patient also has a guardian capable of consent,” says Sarah Hornack, Ph.D., a clinical psychologist at Children’s National and the study’s first author. “A very important determinant of post-surgical success for any young candidate, however, is a support structure to help them with weight-loss surgery requirements. Often, we see that adolescents with lower cognitive function already have a well-established support system in place to assist them with other care needs, that can easily adapt to providing structure and follow through after weight-loss surgery, too.”

The study reviewed outcomes for 63 adolescents ranging in age from 13 to 24 years old with an average body mass index of 51.2, all of whom were part of the bariatric surgery program at Children’s National Health System. The participants were diagnosed with cognitive impairment or intellectual disability via standardized cognitive assessments as part of a preoperative psychological evaluation or through a previous diagnosis. This study adds to the body of research that is helping to create standard criteria for bariatric surgery in adolescents and teenagers.

Children’s National is one of only a few children’s hospitals with accreditation from the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program of the American College of Surgeons and the American Society for Metabolic and Bariatric Surgery to offer bariatric surgery for adolescents with severe obesity. The extraordinary diversity of the patient population in Washington, D.C., including high rates of young people with obesity, allows the team to collect more comprehensive information about successful interventions across subgroups, including cognitive impairment or developmental disabilities, than nearly every other center in the United States.

“We’re happy to contribute evidence that can help families and care providers make informed health decisions for young people with intellectual disabilities or cognitive impairments. So many families are hoping to make sure that their children, despite disabilities, can be as healthy as possible in the long term,” says Eleanor Mackey, Ph.D., who is also a clinical psychologist at Children’s National and served as the study’s senior author. “Though the sample size is small, it does give credence to the idea that for many adolescents and teenagers, weight loss surgery may be a really viable option regardless of pre-existing conditions such as intellectual ability or cognitive function.”

Tracing the history of aggrecan gene mutations

M and her daughter

M takes a photo with her daughter in Washington, where they learned they have an ACAN gene mutation that causes short stature.

On Sunday, April 28, 2019 a team of researchers received the 2019 Human Growth Award at the Pediatric Endocrine Society’s Annual Meeting for their abstract, entitled “Clinical Characterization and Trial of Growth Hormone in Patients with Aggrecan Deficiency: 6 Month Data,” and presented this at the PES Presidential Poster Session.

Eirene Alexadrou, M.D., a fellow at Cincinnati Children’s Hospital Medical Center, accepted the award and honorarium, while ongoing research is underway. This study started in 2017, with the objective of characterizing the phenotypic spectrum and response to a standardized regimen of growth hormone in a small cohort of 10 patients and their families.

In 2017, Andrew Dauber, M.D., MMSc., the division chief of endocrinology at Children’s National Health System, led an international consortium of researchers in publishing a manuscript describing the phenotypic spectrum of 103 individuals – 70 adults and 33 children, including 57 females and 46 males – from 20 families with aggrecan gene (ACAN) mutations.

Dr. Dauber and his colleagues have established that short stature and accelerated bone age is common among people with ACAN mutations. In a review of retrospective data, including patients treated with a variety of growth-promoting therapies at varying doses, the research team found that over the first one, two and three years of treatment, the standard deviation scores (SDS) for height increased by .4, .7 and 1, respectively. The current abstract now describes seven children enrolled in a prospective standardized trial of growth hormone therapy. After six months of treatment, the children have increased their height SDS by an average of 0.46.

Additionally, the researchers are performing an in-depth look at the joint effects, including special MRIs of the knees. They found that two of the children had a problem with their knee cartilage called osteochondritis dissecans. They had not yet presented with clinical symptoms. The researchers hope that early intervention with physical therapy can help prevent significant joint disease in the future.

M and her mother and daughter in Cincinnati

M, her daughter, and M’s mother take a photo in Cincinatti, where they are pariticipating in a clinical trial for aggrecan deficiency.

“Providing growth hormone therapy to children with ACAN gene mutations is relatively new in the field of pediatric endocrinology,” notes Dr. Dauber. “Previously, the assumption was that this was just short stature. We’ll continue to diagnose ACAN mutations in a clinical setting and work with families to reduce the risk of complications, such as joint problems or early-onset arthritis, which may co-occur with this gene mutation.”

As an example, Dr. Dauber met an 8-year-old patient several months ago who presented with symptoms of short stature. The patient is healthy, confident and still growing so her mother wasn’t worried about her but she made the appointment to see if there was an underlying cause to her daughter’s short stature. Her family history revealed clues to an ACAN mutation, which was later confirmed through genetic tests. Her mom, M, stands 4’8; her grandmother is 4’9. Her great grandmother was short and her great, great grandfather was 5’1. Short stature and joint problems run in the family. Once M mentioned she had osteochondritis dissecans and a hip replacement, she provided a textbook case study for carrying the ACAN mutation.

After the appointment, M shared the news with her mother about the possibility of having aggrecan deficiency. After taking genetic tests, M, her mother and M’s daughter learned they all have the ACAN mutation, and enrolled in the study that Dr. Dauber is guiding. Suddenly, it all made sense. After examining family photos, they traced the ACAN mutation back through four generations.

They could tell what relatives had an altered copy of the ACAN gene. M had it, while her two sisters did not. M’s mother was an only child, so she didn’t have aunts or uncles to compare her mother’s height to, but M’s grandmother was short, while her grandmother’s brother was average height. Although her mother’s family was from Germany, she learned that there is no specific ancestry associated with this mutation. It happens by chance and is passed down from a single parent to, on average, half of their children, a form of genetic inheritance called autosomal dominant transmission.

Ms great grandmother and grandfather

M’s great grandfather was noticeably shorter than her great grandmother, who was 5’4.

Through further research, M learned that the ACAN gene provides instructions for producing aggrecan protein, which is essential for bone growth, as well as for the stability of cartilage that lines bones and joints, explaining her recurring joint problems.

She also looked into the future, examining potential risk factors for her daughter: joint pain and bone conditions, which could contribute to arthritis, hip dysplasia and back problems.

The diagnosis now makes it easier for M and her daughter to favor bone-building activities that are easy on the joints, like swimming or water aerobics, instead of gymnastics and weight lifting. After having a hip replacement, M was careful to supplement with calcium and vitamin D. Now, she’ll take the same steps to ensure optimal bone health for her daughter. She’ll work with orthopedic specialists as her daughter grows into her pre-teen and adolescent years, carefully monitoring joint pain – altering activities that are tough on the joints, as necessary.

M let her daughter make a decision about growth hormone therapy, which she decided to try. The benefits of the treatment, increased height, carry inconveniences, such as taking daily shots, but they are sticking with it.

“We’re at the tip of the iceberg with research that explores this gene mutation,” says Dr. Dauber. “We’ll continue to study these families, and more, over time to assess growth patterns and  gene expression, which may reveal other mutations associated with short stature or joint problems, and guide future treatment options. It was a coincidence that this family had the ACAN mutation and scheduled an appointment, while we’re conducting this study. Otherwise, they may not have had an answer since this is fairly new research.”

M and her daughter are happy to be part of this study, which they will participate in for the next few years. M’s mother is also glad to participate. She made a different choice, decades ago, to reject hormone treatment when it was offered to her for undiagnosed short stature, but she’s sharing genetic clues, which may influence treatment options for her granddaughter and for her family’s next generation.

The original study, “Clinical Characterization of Patients with Autosomal Dominant Short Stature due to Aggrecan Muations,” appeared in the Feb. 2017 issue of the Journal of Clinical Endocrinology and Metabolism, and published as an online advance on Nov. 21, 2016.

Thirty-six researchers collaborated on this original paper, which was funded by 16 international health institutes and foundations, including the Eunice Kennedy Shriver National Institute of Child Health and Human Development at the National Institutes of Health, the Swedish Research Council, the Swedish Governmental Agency for Innovation Systems, the Marianne and Marcus Wallenberg Foundation, the Stockholm County Council, the Swedish Society of Medicine, Byggmastare Olle Engkvist’s Foundation, the Sao Paulo Research Foundation, the Spanish Ministry of Education and Science, the Czech Health Research Council and the Ministry of Health, Czech Republic.

“The advent of different technologies and techniques over the years allowed pieces of her diagnosis to be made – and then brought all together,” says Andrew Dauber, M.D., MMSc.

After 20 years, a patient’s family received an answer to a decades-long genetic mystery. Their daughter had two rare disorders, Angelman syndrome and P450scc deficiency, which was detected after researchers found out she had uniparental disomy, two copies of chromosome 15 from one parent and none from another.

The research paper, entitled “Adrenal Insufficiency, Sex Reversal and Angelman Syndrome due to Uniparental Disomy Unmasking a Mutation in CYP11A1,” was published on March 22, 2018, and recognized as the best novel insight paper published by Hormone Research in Paediatrics in 2018, announced at the Pediatric Endocrine Society’s Annual Meeting in Baltimore on Saturday, April 27, 2019.

By using a variety of genetic tools, including whole-exome sequencing, microarray analyses and in-vitro modeling for gene splicing, the researchers were able to confirm this patient had uniparental disomy, a recessive genetic condition. They learned that after she received two impaired copies of chromosome 15 from her father, this woman developed a hormonal problem that led to adrenal insufficiency and sex reversal. This explained why she physically presented as a female, despite having testes and a Y-chromosome. It also explained other symptoms, including developmental delays and seizures.

“It’s a unique conglomeration of symptoms, manifested by the combination of these two very rare disorders,” says Andrew Dauber, M.D., MMSc., the division chief of endocrinology at Children’s National Health System and a guiding research author of this study. “The advent of different technologies and techniques over the years allowed pieces of her diagnosis to be made – and then brought together, commencing a 20-year diagnostic odyssey.”

For example, each of the conditions this patient has is known and rare: Angelman syndrome affects about one in 10 to 20,000 people in the U.S. Typical symptoms include those observed in this patient: delayed development, intellectual disability, speech impairment and seizures. Side-chain cleavage disorder, which leads to adrenal disorders and sex reversal, is also very rare. In 2005 the chances of survival with a P450scc defect were slim, but since then more than 28 infants have been diagnosed with this gene deficiency, which is required to convert cholesterol to pregnenolone, a hormone in the adrenal gland.

Dr. Dauber notes the chances of this occurring again are highly unlikely. The odds here are one in a gazillion. In this case, one disorder unmasked another, leaving researchers with new insights into the methodology for unraveling ultra-rare genetic disorders or for more common rare conditions.

“Knowing about the gene that caused the adrenal insufficiency and understanding this etiology won’t change medical care for this patient, but it will change the way researchers think about genetic detective work and about combining different technologies,” says Dr. Dauber. “We know that genetic disorders can be complex presentations of different disorders combined. This patient didn’t have one disorder, but three.”

When asked about the significance of the award, Dr. Dauber notes that, “It’s not that other people haven’t recognized this concept before, but this case is a striking example of it. Different technologies will unveil different types of genetic changes, which is why you have to use the right technology or the right technologies in the right combination to piece together the whole picture.”

Ahlee Kim, M.D., the lead study author and a clinical research fellow at Cincinnati Children’s Hospital Medical Center, will receive the award and the honorarium.

Additional study authors include Masanobu Fujimoto, Ph.D., Vivian Hwa, Ph.D., and Philippe Backeljauw, M.D., from Cincinnati Children’s Hospital.

The research was supported by grant K23HD07335, awarded to Dr. Dauber, from the Eunice Kennedy Shriver National Institute of Child Health and Human Development of the National Institutes of Health (NIH). Additional funding included grant 1UL1TR001425 from the NIH’s National Center for Advancing Translational Sciences.

Billie Lou Short, M.D., received the Ninth Annual Mentorship Award in Clinical Science.

People joke that Billie Lou Short, M.D., chief of Children’s Division of Neonatology, invented extracorporeal membrane oxygenation, known as ECMO for short. While Dr. Short did not invent ECMO, under her leadership Children’s National was the first pediatric hospital to use it. And over decades Children’s staff have perfected its use to save the lives of tiny, vulnerable newborns by temporarily taking over for their struggling hearts and lungs. For two consecutive years, Children’s neonatal intensive care unit has been named the nation’s No. 1 for newborns by U.S. News & World Report. “Despite all of these accomplishments, Dr. Short’s best legacy is what she has done as a mentor to countless trainees, nurses and faculty she’s touched during their careers. She touches every type of clinical staff member who has come through our neonatal intensive care unit,” says An Massaro, M.D., director of residency research.

For these achievements, Dr. Short received the Ninth Annual Mentorship Award in Clinical Science.

Anna Penn, M.D., Ph.D., has provided new insights into the central role that the placental hormone allopregnanolone plays in orderly fetal brain development, and her research team has created novel experimental models that mimic some of the brain injuries often seen in very preterm babies – an essential step that informs future neuroprotective strategies. Dr. Penn, a clinical neonatologist and developmental neuroscientist, “has been a primary adviser for 40 mentees throughout their careers and embodies Children’s core values of Compassion, Commitment and Connection,” says Claire-Marie Vacher, Ph.D.

For these achievements, Dr. Penn was selected to receive the Ninth Annual Mentorship Award in Basic and Translational Science.

The mentorship awards for Drs. Short and Penn were among dozens of honors given in conjunction with “Frontiers in Innovation,” the Ninth Annual Research and Education Week (REW) at Children’s National. In addition to seven keynote lectures, more than 350 posters were submitted from researchers – from high-school students to full-time faculty – about basic and translational science, clinical research, community-based research, education, training and quality improvement; five poster presenters were showcased via Facebook Live events hosted by Children’s Hospital Foundation.

Two faculty members won twice: Vicki Freedenberg, Ph.D., APRN, for research about mindfulness-based stress reduction and Adeline (Wei Li) Koay, MBBS, MSc, for research related to HIV. So many women at every stage of their research careers took to the stage to accept honors that Naomi L.C. Luban, M.D., Vice Chair of Academic Affairs, quipped that “this day is power to women.”

Getting to know SPR’s future President, Beth Tarini, M.D., MS

Beth Tarini

Quick. Name four pillar pediatric organizations on the vanguard of advancing pediatric research.

Most researchers and clinicians can rattle off the names of the Academic Pediatric Association, the American Academy of Pediatrics and the American Pediatric Society. But that fourth one, the Society for Pediatric Research (SPR), is a little trickier. While many know SPR, a lot of research-clinicians simply do not.

Over the next few years, Beth A. Tarini, M.D., MS, will make it her personal mission to ensure that more pediatric researchers get to know SPR and are so excited about the organization that they become active members. In May 2019 Dr. Tarini becomes Vice President of the society that aims to stitch together an international network of interdisciplinary researchers to improve kids’ health. Four-year SPR leadership terms begin with Vice President before transitioning to President-Elect, President and Past-President, each for one year.

Dr. Tarini says she looks forward to working with other SPR leaders to find ways to build more productive, collaborative professional networks among faculty, especially emerging junior faculty. “Facilitating ways to network for research and professional reasons across pediatric research is vital – albeit easier said than done. I have been told I’m a connector, so I hope to leverage that skill in this new role,” says Dr. Tarini, associate director for Children’s Center for Translational Research.

“I’m delighted that Dr. Tarini was elected to this leadership position, and I am impressed by her vision of improving SPR’s outreach efforts,” says Mark Batshaw, M.D., Executive Vice President, Chief Academic Officer and Physician-in-Chief at Children’s National. “Her goal of engaging potential members in networking through a variety of ways – face-to-face as well as leveraging digital platforms like Twitter, Facebook and LinkedIn – and her focus on engaging junior faculty will help strengthen SPR membership in the near term and long term.”

Dr. Tarini adds: “Success to me would be leaving after four years with more faculty – especially junior faculty – approaching membership in SPR with the knowledge and enthusiasm that they bring to membership in other pediatric societies.”

SPR requires that its members not simply conduct research, but move the needle in their chosen discipline. In her research, Dr. Tarini has focused on ensuring that population-based newborn screening programs function efficiently and effectively with fewer hiccups at any place along the process.

Thanks to a heel stick to draw blood, an oxygen measurement, and a hearing test, U.S. babies are screened for select inherited health conditions, expediting treatment for infants and reducing the chances they’ll experience long-term health consequences.

“The complexity of this program that is able to test nearly all 4 million babies in the U.S. each year is nothing short of astounding. You have to know the child is born – anywhere in the state – and then between 24 and 48 hours of birth you have to do testing onsite, obtain a specific type of blood sample, send the blood sample to an off-site lab quickly, test the sample, find the child if the test is out of range, get the child evaluated and tested for the condition, then send them for treatment. Given the time pressures as well as the coordination of numerous people and organizations, the fact that this happens routinely is amazing. And like any complex process, there is always room for improvement,” she says.

Dr. Tarini’s research efforts have focused on those process improvements.

As just one example, the Advisory Committee on Heritable Disorders in Newborns and Children, a federal advisory committee on which she serves, was discussing how to eliminate delays in specimen processing to provide speedier results to families. One possible solution floated was to open labs all seven days, rather than just five days a week. Dr. Tarini advocated for partnering with health care engineers who could help model ways to make the specimen transport process more efficient, just like airlines and mail delivery services. A more efficient and effective solution was to match the specimen pick-up and delivery times more closely with the lab’s operational times – which maximizes lab resources and shortens wait times for parents.

Conceptual modeling comes so easily for her that she often leaps out of her seat mid-sentence, underscoring a point by jotting thoughts on a white board, doing it so often that her pens have run dry.

“It’s like a bus schedule: You want to find a bus that not only takes you to your destination but gets you there on time,” she says.

Dr. Tarini’s current observational study looks for opportunities to improve how parents in Minnesota and Iowa are given out-of-range newborn screening test results – especially false positives – and how that experience might shake their confidence in their child’s health as well as heighten their own stress level.

“After a false positive test result, are there parents who walk away from newborn screening with lingering stress about their child’s health? Can we predict who those parents might be and help them?” she asks.

Among the challenges is the newborn screening occurs so quickly after delivery that some emotionally and physically exhausted parents may not remember it was done. Then they get a call from the state with ominous results. Another challenge is standardizing communication approaches across dozens of birthing centers and hospitals.

“We know parents are concerned after receiving a false positive result, and some worry their infant remains vulnerable,” she says. “Can we change how we communicate – not just what we say, but how we say it – to alleviate those concerns?”
