Parasitic eggs trigger upregulation in genes associated with inflammation

January 29, 2020

Of the 200 million people around the globe infected with Schistosomiasis, about 100 million of them were sickened by the parasite Schistosoma haematobium.

Of the 200 million people around the globe infected with Schistosomiasis, about 100 million of them were sickened by the parasite Schistosoma haematobium. As the body reacts to millions of eggs laid by the blood flukes, people can develop fever, cough and abdominal pain, according to the Centers for Disease Control and Prevention. Schistosomiasis triggered by S. haematobium can also include hematuria, bladder calcification and bladder cancer.

Despite the prevalence of this disease, there are few experimental models specifically designed to study it, and some tried-and-true preclinical models don’t display the full array of symptoms seen in humans. It’s also unclear how S. haematobium eggs deposited in the host bladder modulate local tissue gene expression.

To better understand the interplay between the parasite and its human host, a team led by Children’s National Hospital injected 6,000 S. haematobium eggs into the bladder wall of seven-week-old experimental models.

After four days, they isolated RNA for analysis, comparing differences in gene expression in various treatment groups, including those that had received the egg injection and experimental models whose bladders were not exposed to surgical intervention.

Using the Database for Annotation, Visualization and Integrated Discovery (DAVID) – a tool that helps researchers understand the biological meaning of a long list of genes – the team identified commonalities with other pathways, including malaria, rheumatoid arthritis and the p53 signaling pathway, the team recently presented during the American Society of Tropical Medicine and Hygiene 2019 annual meeting. Some 325 genes were differentially expressed, including 34 genes in common with previous microarray data.

“Of particular importance, we found upregulation in genes associated with inflammation and fibrosis. We also now know that the body may send it strongest response on the first day it encounters a bolus of eggs,” says Michael Hsieh, M.D., Ph.D., director of transitional urology at Children’s National, and the research project’s senior author. “Next, we need to repeat these experiments and further narrow the list of candidate genes to key genes associated with immunomodulation and bladder cancer.”

In addition to Dr. Hsieh, presentation co-authors include Lead Author Kenji Ishida, Children’s National; Evaristus Mbanefo and Nirad Banskota, National Institutes of Health; James Cody, Vigene Biosciences; Loc Le, Texas Tech University; and Neil Young, University of Melbourne.

IPSE infiltrates nuclei through clathrin-mediated endocytosis

January 29, 2020

IPSE, one of the important proteins excreted by the parasite Schistosoma mansoni, infiltrates human cellular nuclei through clathrin-coated vesicles, like this one.

IPSE, one of the important proteins excreted by the parasite Schistosoma mansoni infiltrates human cellular nuclei through clathrin-mediated endocytosis (a process by which cells absorb metabolites, hormones and proteins), a research team led by Children’s National Hospital reported during the American Society of Tropical Medicine and Hygiene 2019 annual meeting.

Because the public health toll from the disease this parasite causes, Schistosomiasis, is second only to malaria in global impact, research teams have been studying its inner workings to help create the next generation of therapies.

In susceptible host cells – like urothelial cells, which line the urinary tract – IPSE modulates gene expression, increasing cell proliferation and angiogenesis (formation of new blood vessels). On a positive note, neurons appear better able to fend off its nucleus-infiltrating ways.

“We know that IPSE contributes to the severity of symptoms in Schistosomiasis, which leads some patients to develop bladder cancer, which develops from the urothelial lining of the bladder. Our team’s carefully designed experiments reveal IPSE’s function in the urothelium and point to the potential of IPSE playing a therapeutic role outside of the bladder,” says Michael Hsieh, M.D., Ph.D., director of transitional urology at Children’s National and the research project’s senior author.

In addition to Dr. Hsieh, research co-authors include Evaristus Mbanefo, Ph.D.; Kenji Ishida, Ph.D.; Austin Hester, M.D.; Catherine Forster, M.D.; Rebecca Zee, M.D., Ph.D.; and Christina Ho, M.D., all of Children’s National; Franco Falcone, Ph.D., University of Nottingham; and Theodore Jardetzky, Ph.D., and Luke Pennington, M.D., Ph.D., candidate, both of Stanford University.

Children’s National co-hosts the 4th International Symposium on hypothalamic hamartomas

December 16, 2019

The Children’s National Hospital’s Comprehensive Pediatric Epilepsy Program co-hosted the 4th International Symposium on Hypothalamic Hamartomas held in September 2019 in Washington, D.C.

The 2019 Symposium focused on the psychiatric, neuropsychological, neurological and endocrinological comorbidities of Hypothalamic Hamartomas (HH). The participants also looked at treating the whole person – in addition to the tumor – covering the cognitive, physical, emotional and intellectual impacts of HH.

Attendees at the 4th International Symposium on Hypothalamic Hamartomas.

Presenters at the Symposium included experts from around the world, such as Children’s National’s Chief of the Divisions of Child Neurology and of Epilepsy and Neurophysiology,, William D. Gaillard, M.D., who moderated the entire event and served as the HH Symposium Chair on the Symposium Steering Committee. Dr. Gaillard also facilitated a presentation titled “Developing a New Paradigm for Assessing, Surveilling, & Treating HH Comorbidities” and another presentation titled, “Set 3 Year Research Roadmap & Top Priorities.”

Senior Vice President for the Center for Neuroscience & Behavioral Health, Roger Packer, M.D., also presented at the event on treatments being used in other hypothalamic hamartoma syndromes which may possibly have opportunities for success with treatment of HH.

Orthopaedic surgeon shares expertise at Baltimore Limb Deformity Course

December 5, 2019

Dr. Tabaie oversees a hands-on lab session focused on teaching orthopaedic surgeons and other allied health professionals proper assessment and placement of corrective hardware for limb deformities.

Sean Tabaie served as a lab instructor to guide hands-on applications of the latest devices for treatment of limb deformities.

Earlier this year, Children’s National orthopaedic surgeon Sean Tabaie, M.D., served as a faculty member for one of the most highly regarded courses focused on limb deformities, the 29^th Annual Baltimore Limb Deformity Course. The course is presented each year by the International Center for Limb Lengthening.

The event brings together nearly 400 orthopaedic physicians, podiatrists and allied health professionals from 36 countries and 33 states to learn from pre-eminent surgical experts in these conditions. The three-day meeting provides lecture content as well as hands-on opportunities to practice care and treatment of limb deformities in both adults and children.

Dr. Tabaie served as a lab instructor, sharing expertise and in-depth knowledge from the pediatric perspective about how to assess limb alignment and plan corrections for specific deformities. The faculty teams also outlined current best practices for correction of several specific deformities, including Blount’s deformity, using internal and external devices.

“It was an honor to be asked to serve as faculty alongside these pre-eminent leaders in the field of limb deformity,” he says. “It is workshops like these that give us the opportunity to share what we know and also learn from the experience of others. And ultimately, lending expertise to these courses helps everyone more effectively assess and treat limb deformities in children and adults around the world.”

Tailored T-cell therapies neutralize viruses that threaten kids with PID

November 18, 2019

t-cells

Tailored T-cells specially designed to combat a half dozen viruses are safe and may be effective in preventing and treating multiple viral infections, according to research led by Children’s National Hospital faculty.

Catherine Bollard, M.B.Ch.B., M.D., director of the Center for Cancer and Immunology Research at Children’s National and the study’s senior author, presented the teams’ findings Nov. 8, 2019, during a second-annual symposium jointly held by Children’s National and the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH). Children’s National and NIAID formed a research partnership in 2017 to develop and conduct collaborative clinical research studies focused on young children with allergic, immunologic, infectious and inflammatory diseases. Each year, they co-host a symposium to exchange their latest research findings.

According to the NIH, more than 200 forms of primary immune deficiency diseases impact about 500,000 people in the U.S. These rare, genetic diseases so impair the person’s immune system that they experience repeated and sometimes rare infections that can be life threatening. After a hematopoietic stem cell transplantation, brand new stem cells can rebuild the person’s missing or impaired immune system. However, during the window in which the immune system rebuilds, patients can be vulnerable to a host of viral infections.

Because viral infections can be controlled by T-cells, the body’s infection-fighting white blood cells, the Children’s National first-in-humans Phase 1 dose escalation trial aimed to determine the safety of T-cells with antiviral activity against a half dozen opportunistic viruses: adenovirus, BK virus, cytomegalovirus (CMV), Epstein-Barr virus (EBV), Human Herpesvirus 6 and human parainfluenza-3 (HPIV3).

Eight patients received the hexa-valent, virus-specific T-cells after their stem cell transplants:

Three patients were treated for active CMV, and the T-cells resolved their viremia.
Two patients treated for active BK virus had complete symptom resolution, while one had hemorrhagic cystitis resolved but had fluctuating viral loads in their blood and urine.
Of two patients treated prophylactically, one developed EBV viremia that was treated with rituximab.

Two additional patients received the T-cell treatments under expanded access for emergency treatment, one for disseminated adenoviremia and the other for HPIV3 pneumonia. While these critically ill patients had partial clinical improvement, they were being treated with steroids which may have dampened their antiviral responses.

“These preliminary results show that hexaviral-specific, virus-specific T-cells are safe and may be effective in preventing and treating multiple viral infections,” says Michael Keller, M.D., a pediatric immunologist at Children’s National and the lead study author. “Of note, enzyme-linked immune absorbent spot assays showed evidence of antiviral T-cell activity by three months post infusion in three of four patients who could be evaluated and expansion was detectable in two patients.”

In addition to Drs. Bollard and Keller, additional study authors include Katherine Harris M.D.; Patrick J. Hanley Ph.D., assistant research professor in the Center for Cancer and Immunology; Allistair Abraham, M.D., a blood and marrow transplantation specialist; Blachy J. Dávila Saldaña, M.D., Division of Blood and Marrow Transplantation; Nan Zhang Ph.D.; Gelina Sani BS; Haili Lang MS; Richard Childs M.D.; and Richard Jones M.D.

Virtual cardiology follow-ups may save families time and money

November 14, 2019

Virtual cardiology follow-ups via computer or smartphone are a feasible alternative to in-person patient follow-ups for some pediatric cardiac conditions.

A poster presentation at the AHA Scientific Sessions shows successful implementation of virtual care delivered directly to patients and families via technology.

Health provider follow-ups delivered via computer or smartphone is a feasible alternative to in-person patient follow-ups for some pediatric cardiac conditions, according to the findings of a pilot study presented at the AHA Scientific Sessions this week.

“We’ve used telemedicine in pediatric cardiology for physician-to-physician communications for years at Children’s National, thanks to cardiologists like Dr. Craig Sable,” says Ashraf Harahsheh, M.D., cardiologist at Children’s National Hospital and senior author of the study. “But this is the first time we’ve really had the appropriate technology to speak directly to patients and their families in their homes instead of requiring an in-person visit.”

“We developed it [telemedicine] into a primary every day component of reading echocardiograms around the region and the globe,” says Craig Sable, M.D., associate chief of cardiology at Children’s National. “Telemedicine has enabled doctors at Children’s National to extend our reach to improve the care of children and avoid unnecessary transport, family travel and lost time from work.”

Participants in the virtual visit pilot study were previously established patients with hyperlipidemia, hypercholesterolemia, syncope, or who needed to discuss cardiac testing results. The retrospective sample included 18 families who met the criteria and were open to the virtual visit/telehealth follow up option between 2016 and 2019. Six months after their virtual visit, none of the participants had presented urgently with a cardiology issue. While many (39%) had additional visits with cardiology scheduled as in person, none of those subsequent in-person visits were a result of a deficiency related to the virtual visit.

“There are many more questions to be answered about how best to appropriately use technology advances that allow us to see and hear our patients without requiring them to travel a great distance,” adds Dr. Harahsheh. “But my team and I were encouraged by the results of our small study, and by the anecdotal positive reviews from families who participated. We’re looking forward to determining how we can successfully and cost-effectively implement these approaches as additional options for our families to get the care they need.”

The project was supported by the Research, Education, Advocacy, and Child Health Care (REACH) program within the Children’s National Hospital Pediatric Residency Program.

BPA analogues may be less likely to disrupt heart rhythm

November 14, 2019

Some chemical alternatives to plastic bisphenol-a (BPA), which is still commonly used in medical settings such as operating rooms and intensive care units, may be less disruptive to heart electrical function than BPA.

A poster at the AHA Scientific Sessions suggests bisphenol-s (BPS) and bisphenol-f (BPF) may have less impact on heart function than bisphenol-a (BPA).

Some chemical alternatives to plastic bisphenol-a (BPA), which is still commonly used in medical settings such as operating rooms and intensive care units, may be less disruptive to heart electrical function than BPA, according to a pre-clinical study that explored how the structural analogues bisphenol-s (BPS) and bisphenol-f (BPF) interact with the chemical and electrical functions of heart cells.

The findings suggest that in terms of toxicity for heart function, these chemicals that are similar in structure to BPA may actually be safer for medically fragile heart cells, such as those in children with congenital heart disease. Previous research has found a high likelihood that BPA exposure may impact the heart’s electrical conductivity and disrupt heart rhythm, and patients are often exposed to the plastic via clinical equipment found in intensive care and in the operating room.

“There are still many questions that need to be answered about the safety and efficacy of using chemicals that look and act like BPA in medical settings, especially in terms of their potential contribution to endocrine disruption,” says Nikki Gillum Posnack, Ph.D., the poster’s senior author and a principal investigator in the Sheikh Zayed Institute for Pediatric Surgical Innovation at Children’s National Hospital. “What we can say is that, in this initial pre-clinical investigation, it appears that these structural analogues have less of an impact on the electrical activity within the heart and therefore, may be less likely to contribute to dysrhythmias.”

Future studies will seek to quantify the risk that these alternative chemicals pose in vulnerable populations, including pediatric cardiology and cardiac surgery patients. Since pediatric patients’ hearts are still growing and developing, the interactions may be different than what was seen in this pilot study.

Can cells collected from bone marrow stimulate generation of new neurons in babies with CHD?

November 13, 2019

The goal of the study will be to optimize brain development in babies with congenital heart disease (CHD) who sometimes demonstrate delay in the development of cognitive and motor skills.

An upcoming clinical trial at Children’s National Hospital will harness cardiopulmonary bypass as a delivery mechanism for a novel intervention designed to stimulate brain growth and repair in children who undergo cardiac surgery for congenital heart disease (CHD).

The NIH has awarded Children’s National $2.5 million to test the hypothesis that mesenchymal stromal cells (MSCs), which have been shown to possess regenerative properties and the ability to modulate immune responses in a variety of diseases, collected from allogeneic bone marrow, may promote regeneration of damaged neuronal and glial cells in the early postnatal brain. If successful, the trial will determine the safety of the proposed treatment in humans and set the stage for a Phase 2 efficacy trial of what could potentially be the first treatment for delays in brain development that happen before birth as a consequence of congenital heart disease. The study is a single-center collaboration between three Children’s National physician-researchers: Richard Jonas, M.D., Catherine Bollard, M.B.Ch.B., M.D. and Nobuyuki Ishibashi, M.D.

Dr. Jonas, chief of cardiac surgery at Children’s National, will outline the trial and its aims on Monday, November 18, 2019, at the American Heart Association’s Scientific Sessions 2019. Dr. Jonas was recently recognized by the Cardiac Neurodevelopmental Outcome Collaborative for his lifelong research of how cardiac surgery impacts brain growth and development in children with CHD.

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

November 8, 2019

“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.

Biliary complication rates similar for kids and adults after weight-loss surgery

November 5, 2019

“We definitely need more research, across a more diverse population, to understand the mechanisms behind this higher likelihood of acute pancreatitis in pediatric patients,” says Evan Nadler, M.D., “More importantly, this study provides a proof point that weight-loss surgery doesn’t pose any higher risk of biliary complications for kids than it does for adults.”

Adolescents and teens experience biliary side effects after weight-loss surgery at about the same rate as adults. However, in younger patients, the symptoms are more likely to manifest as pancreatic inflammation, or acute pancreatitis, according to a new study published in the November issue of the journal Obesity.

“Biliary issues after laparoscopic sleeve gastrectomy occur with about the same frequency in pediatric patients as they do in adults,” says Evan Nadler, M.D., senior author on the study and director of the Bariatric Surgery Program at Children’s National Hospital. “We were surprised, however, to find that the small number of pediatric patients who do experience these complications seem to be more likely to have acute pancreatitis as a result. In adults, it’s more commonly the gall bladder that acts up as opposed to the pancreas.”

The study included 309 patients without previous or concurrent history of biliary disease or gallstones who had undergone laparoscopic sleeve gastrectomy at Children’s National. Twenty-one patients, or 6.7% of the cohort, were diagnosed with biliary disease after surgery. Sixty-two percent of the pediatric patients with biliary disease also showed signs of acute pancreatitis, while only one-third of those with post-operative biliary disease presented with a gallstone blockage, or biliary colic. In adults, biliary colic is a primary symptom after surgery and far fewer adults experience acute pancreatitis.

“We definitely need more research, across a more diverse population, to understand the mechanisms behind this higher likelihood of acute pancreatitis in pediatric patients. More importantly, this study provides a proof point that weight-loss surgery doesn’t pose any higher risk of biliary complications for kids than it does for adults.”

Obesity’s editorial team selected the study as one of the Top 5 most innovative scientific research studies to prevent and treat obesity in 2019. It appears in a special section of the November 2019 print edition. Dr. Nadler will present his findings during the Obesity Journal Symposium on Nov. 5, 2019, as part of ObesityWeek®, the annual meeting of The Obesity Society.

“We’ve got one of the largest, if not the largest, weight-loss surgery programs dedicated solely to caring for children and adolescents,” adds Dr. Nadler. “That gives us a unique ability to collect and analyze a statistically significant sample of pediatric-specific patient data and really contribute a better understanding of how bariatric surgery specifically impacts younger patients.”

In late October 2019, the American Academy of Pediatrics issued guidance with the aim of providing severely obese teens easier access to bariatric surgery.

“Our study is just the latest contribution to a significant body of evidence that weight-loss surgery should be considered a viable treatment approach for children and teenagers with severe obesity, an idea that is now endorsed by the nation’s largest organization of pediatricians,” he points out.

The Obesity Journal Symposium occurs on Tuesday, Nov. 5, 2019, from 3:30 – 5:00 p.m. at the Mandalay Bay South Convention Center in Las Vegas, Nev. ObesityWeek® is a partnership of The Obesity Society and the American Society for Metabolic and Bariatric Surgery.

The five easy pieces of literature appraisal for busy front-line providers

November 5, 2019

To help practitioners appraise medical literature, Bernhard Wiedermann, M.D., MA, suggests determining where it fits on this pyramid.

Practitioners often read journal articles to help inform them about best clinical practices and policies, but some may not feel comfortable changing their clinical practice in the absence of published practice guidelines.

During this year’s American Academy of Pediatrics National Conference and Exhibition, Bernhard Wiedermann, M.D., MA, an infectious disease specialist at Children’s National Hospital, spoke to a room full of pediatric providers about how to stay current with medical literature, quickly analyze the material and decide whether to apply it to their practice. “This interactive session served to help primary care pediatric providers understand how to critically appraise what they are reading in medical literature,” says Dr. Wiedermann. “Practitioners need to be able to critically read journal articles to better decide when to apply new studies or recommendations to their clinical practice.”

Dr. Wiedermann’s presentation, entitled “Should that new article change your practice? The five easy pieces of literature appraisal for busy front-line providers,” covered:

Techniques that providers should use when searching and browsing for literature
How to review abstracts for relevant content
How to determine the type of study (Where does it fit on the pyramid?)
Whether or not your patient fits the study population
How to explain findings to parents and patients

At the session, attendees gained the ability to develop a streamlined plan to keep current with the medical literature, apply simple strategies to select and appraise potentially worthwhile articles and discuss new management options with patients and families.

2019 National Maternal & Infant Health Summit

November 5, 2019

Children’s National Hospital participated in the second annual National Maternal & Infant Health Summit which highlights the District’s approaches to ensure the health of women, babies and families. From L to R are: Sahira Long, M.D., Jessica Nash, M.D., Hope Rhodes, M.D., and Kofi Essel, M.D.

Children’s National Hospital participated in the second annual National Maternal & Infant Health Summit hosted by Mayor Muriel Bowser. The summit was built upon highlighting the District’s approaches to ensure the health of women, babies and families, while also seeking to increase public awareness and interest on these topics.

“I enjoyed the summit as a mother, parent, physician and presenter,” said Jessica Nash, M.D., a pediatrician at Children’s National. “I am excited about the future conversations about infant and maternal mortality and the strides needed in the District.”

Nash led a panel titled “Maternal and Infant Mental Health Landscape: Taking Steps to Improve Practice and Policy,” with Hope Rhodes, MD, MPH, Dominique Charlot-Swilley, Ph.D., Leandra Godoy, Ph.D. and Sarah Barclay Hoffman. The discussion identified infant and early childhood mental health resources available in the District, the current state of infant and early childhood mental health, future potential policy changes and the collaborative model that places HealthySteps DC within a child’s primary care medical home.

Children’s National Hospital’s Saharia Long, M.D., discusses the local efforts to improve healthy food access for families.

The day-long summit covered many topics including The Role of Food Policy, Access, and Nutrition in Supporting Positive Outcomes for Families, which focused on national and local efforts to improve healthy food access for families, breastfeeding and babies’ first foods. The discussion was a direct response to feedback on the absence of information about breastfeeding and nutrition during last year’s summit. Sahira Long, M.D., and Kofi Essel, M.D. served as panelists.

“According to the Centers for Disease Control and Prevention (CDC), low rates of breastfeeding add $3 billion a year to medical costs for mothers and children in the U.S.” said Dr. Long. “Breastfeeding is more than an infant feeding choice, it’s a public health decision due to its impact on maternal and infant health.”

The Maternal and Infant Health Summit brings together residents of the District, elected officials, health and education officials and community-based partners to collaborate and explore strategies that will improve perinatal health and address racial disparities in birth outcomes.

All in the family: How to run an effective family meeting

November 4, 2019

Tessie October, M.D., M.P.H., led a qualitative study that discovered an increase in important information shared from families to the physician when physicians had openly responded with empathy and made time for families to share.

When critically ill children are in the intensive care unit (ICU), physicians must often lead difficult discussions with their families about the direction of care. These family conferences can be challenging for both the doctors leading them and for the families, who are unsure of their options, are under emotional strain and who may feel pressured to make decisions.

“We have patients with serious illnesses discussing major decisions and we don’t do a great job thinking about how to structure those meetings,” says Tessie October, M.D., M.P.H., a critical care specialist at Children’s National Hospital.

Dr. October seeks to help doctors better bridge the gap between themselves and families with her presentation entitled “All in the family: How to run an effective family meeting,” which she presented during the American Academy of Pediatrics (AAP) National Conference and Exhibition in New Orleans on October 28^th.

During her session, Dr. October role-played a family conference scenario and allowed the audience to experience key skills needed to successfully facilitate them. “Many people think family conferences are about being nice and assume that physicians know how to do this well,” says October. “There is a skill to navigating the conversation where you ensure that the family hears what you’re saying and you respond to the emotions that follow.”

Dr. October led a qualitative study that discovered an increase in important information shared from families to the physician when physicians had openly responded with empathy and made time for families to share. “Families experience increased satisfaction, physicians become more confident in leading these family conferences and the time needed to make medical decisions is shortened because the family heard the information clearly enough for them to make the decision,” says Dr. October.

Within her study, the 68 recorded conferences that took place at Children’s National pediatric ICU (PICU) showed that physicians missed opportunities to respond to the emotions expressed by a patient’s family in 26% of their interactions. “Families want a doctor to be professional caregiver, to be honest with them, and to present clear information that allows the family to make an informed decision.”

Dr. October and her colleagues intend to help physicians learn to communicate better, starting at Children’s National. “My goal is to expand the program hospital-wide, starting with hematology, neonatology, emergency medicine and cardiology fellows, all of whom will most likely have these difficult treatment and end-of-life discussions with families at some point.”

Empowering pediatricians to reduce preventable firearm injuries and deaths

October 25, 2019

Lenore Jarvis, M.D., MEd, FAAP, will participate in a symposium of surgeons, neurosurgeons and emergency medicine doctors during the American Academy of Pediatrics National Conference and Exhibition – the first time these groups have come together to help reduce the number of kids hurt or killed by firearms.

Lenore Jarvis, M.D., MEd, FAAP, remembers feeling fatigue and frustration when, despite her team’s herculean efforts, a 5-year-old died from accidental gunshot wounds. The preschooler had been feeling playful: He surprised a family member who mistook him for an intruder and fired, fatally wounding the child.

As an Emergency Medicine and Trauma Services specialist at Children’s National Hospital, Dr. Jarvis has cared for kids with a range of firearm-related injuries from accidental shootings, intentional acts of violence or suicide attempts. Even when children survive such traumatic injuries, their lives are indelibly altered.

“We’re trained to save lives, but we also want to prevent childhood injuries, if possible. As I considered this young child’s life ending so prematurely and so tragically, I thought I should do more. I could do more,” recalls Dr. Jarvis, the division’s director of advocacy and health policy.

To that end, in addition to advocacy at the regional and national level, on Oct. 26, 2019, Dr. Jarvis will participate in a four-hour symposium of surgeons, neurosurgeons and emergency medicine doctors during the American Academy of Pediatrics (AAP) National Conference and Exhibition – the first time these groups have come together to explore ways they can help to reduce the number of kids hurt or killed by firearms.

Dr. Jarvis will set the stage for the day’s collective call to action when she counsels pediatricians about how they can advocate within the clinic by simple actions such as:

Asking families if there are firearms in the home
Making time for such conversations during routine care, including well-child visits
Paying special attention to warning signs of suicide and depression
Having frank conversations with parents about curious toddlers

“The safest home is a home without a firearm. If that’s not possible, the firearm should be stored in a locked cabinet with the ammunition stored separately,” she says. “Toddlers are especially curious and they actively explore their environment. An unsecured firearm can be a tragic accident waiting to happen with curious young children in the home. And if teenagers happen upon the weapon, it could be used in a homicide or suicide.”

In addition to empowering clinicians to have these conversations routinely, symposium speakers will emphasize empowering parents to ask other families: “Is there an unlocked gun in your house?”

“It’s no different than a parent of a child with a life-threatening sensitivity to peanuts asking if there are peanuts in any home that child may visit,” she adds. “As one of the leading causes of death among children and youth, unsecured firearms are even more dangerous than peanuts. And families should feel comfortable making informed decisions about whether their children will be safe as they play and socialize with friends.”

Decision support tool reduces unneeded referrals of low-risk patients with chest pain

October 25, 2019

A simple evidence-based change to standard practice could avert needless referrals of low-risk patients to cardiac specialists, potentially saving nearly $4 million in annual health care spending while also easing worried parents’ minds.

Few events strike more fear in parents than hearing their child’s heart “hurts.”

When primary care pediatricians – who are on the frontline of triaging such distressing doctor visits – access a digital helping hand tucked into the patient’s electronic health record to help them make assessments, they are more likely to refer only the patients whose chest pain is rooted in a cardiac problem to a specialist.

That simple evidence-based change to standard practice could avert needless referrals of low-risk patients to cardiac specialists according to a quality-improvement project presented during the American Academy of Pediatrics (AAP) National Conference and Exhibition. This has the potential to save nearly $4 million in annual health care spending while also easing worried parents’ minds.

“Our decision support tool incorporates the know-how of providers and helps them to accurately capture the type of red flags that point to a cardiac origin for chest pain,” says Ashraf Harahsheh, M.D., FACC, FAAP, pediatric and preventive cardiologist and director of Resident Education in Cardiology at Children’s National Hospital. Those red flags include:

Abnormal personal medical history
- Chest pain with exertion
- Exertional syncope
- Chest pain that radiates to the back, jaw, left arm or left shoulder
- Chest pain that increases with supine position
- Chest pain temporarily associated with a fever (>38.4°C)
A worrisome family history, including sudden unexplained death and cardiomyopathy.

“We know that evidence-based tools can be very effective in guiding physician behavior and reducing unnecessary testing and referrals which saves both the health care system in dollars and families in time and anxiety,” Dr. Harahsheh adds.

The abstract builds on a multi-institutional study published in Clinical Pediatrics in 2017 for which Dr. Harahsheh was lead author. More than 620,000 office-based visits (1.3%) to pediatricians in 2012 were for chest pain, he and co-authors wrote at the time. While children often complain of having chest pain, most of the time it is not due to an actual heart problem.

Over recent years, momentum has built for creating an evidence-based approach for determining which children with chest pain to refer to cardiac specialists. In response, the team’s quality-improvement tool, first introduced at two local primary pediatric offices, was expanded to the entire Children’s Pediatricians & Associates network of providers who offer pediatric primary care in Washington, D.C., and Maryland.

One daunting challenge: How to ensure that busy clinicians actually use the tool. To improve adoption, the project team embedded the decision support tool within the patient’s electronic medical record. Now, they seek to make sure the tool gets used by more pediatricians around the country.

“If the chest pain decision support tool/medical red-flags criteria were adopted nationwide, we expect to save a minimum of $3.8 million in health care charges each year,” Dr. Harahsheh says. “That figure is very likely an underestimate of the true potential savings, because we did not calculate the value of lost productivity and other direct costs to families who shuttle from one appointment to the next.”

To ensure the changes stick, the team plans to train fledgling physicians poised to embrace the quality-improvement approach as they first launch their careers, and also look for evangelists within outpatient cardiology and pediatric clinics who can catalyze change.

“These types of quality-improvement projects require a change to the status quo. In order to be successful, we need members of the care team – including frontline clinicians and nurse practitioners – to champion change at the clinic level. With their help, we can continue to refine this tool and move toward nationwide implementation,” he explains.

Autism spectrum disorder risk linked to insufficient placental steroid

October 23, 2019

A study led by Children’s National Hospital and presented during Neuroscience 2019 finds that loss of allopregnanolone, a key hormone supplied by the placenta, leads to long-term structural alterations of the cerebellum – a brain region essential for smooth motor coordination, balance and social cognition – and increases the risk of developing autism.

An experimental model study suggests that allopregnanolone, one of many hormones produced by the placenta during pregnancy, is so essential to normal fetal brain development that when provision of that hormone decreases – as occurs with premature birth – offspring are more likely to develop autism-like behaviors, a Children’s National Hospital research team reports at the Neuroscience 2019 annual meeting.

“To our knowledge, no other research team has studied how placental allopregnanolone (ALLO) contributes to brain development and long-term behaviors,” says Claire-Marie Vacher, Ph.D., lead author. “Our study finds that targeted loss of ALLO in the womb leads to long-term structural alterations of the cerebellum – a brain region that is essential for motor coordination, balance and social cognition – and increases the risk of developing autism,” Vacher says.

According to the Centers for Disease Control and Prevention, about 1 in 10 infants is born preterm, before 37 weeks gestation; and 1 in 59 children has autism spectrum disorder.

In addition to presenting the abstract, on Monday, Oct. 21, Anna Penn, M.D., Ph.D., the abstract’s senior author, will discuss the research with reporters during a Neuroscience 2019 news conference. This Children’s National abstract is among 14,000 abstracts submitted for the meeting, the world’s largest source of emerging news about brain science and health.

ALLO production by the placenta rises in the second trimester of pregnancy, and levels of the neurosteroid peak as fetuses approach full term.

To investigate what happens when ALLO supplies are disrupted, a research team led by Children’s National created a novel transgenic preclinical model in which they deleted a gene essential in ALLO synthesis. When production of ALLO in the placentas of these experimental models declines, offspring had permanent neurodevelopmental changes in a sex- and region-specific manner.

“From a structural perspective, the most pronounced cerebellar abnormalities appeared in the cerebellum’s white matter,” Vacher adds. “We found increased thickness of the myelin, a lipid-rich insulating layer that protects nerve fibers. From a behavioral perspective, male offspring whose ALLO supply was abruptly reduced exhibited increased repetitive behavior and sociability deficits – two hallmarks in humans of autism spectrum disorder.”

On a positive note, providing a single ALLO injection during pregnancy was enough to avert both the cerebellar abnormalities and the aberrant social behaviors.

The research team is now launching a new area of research focus they call “neuroplacentology” to better understand the role of placenta function on fetal and newborn brain development.

“Our team’s data provide exciting new evidence that underscores the importance of placental hormones on shaping and programming the developing fetal brain,” Vacher notes.

7th Annual Pediatric Device Innovation Symposium

October 11, 2019

The event featured an onstage discussion by Melinda Richter, global head of Johnson & Johnson Innovation – JLABS and Dr. Kurt Newman, M.D., president and CEO of Children’s National Hospital, about the power of collaboration to spur innovation.

The 7^th Annual Pediatric Device Innovation Symposium, presented by Children’s National Hospital, recently brought together stakeholders from across the clinical, investor, business and regulatory sectors of pediatric device development for a day-long program focused on closing the wide gap that exists between the number of medical devices developed for adults and the significantly smaller number developed for children.

Co-located with AdvaMed’s The MedTech Conference for the third consecutive year, the symposium featured an opening keynote address by Melinda Richter, global head of Johnson & Johnson Innovation – JLABS, who was later joined Kurt Newman, M.D., president and CEO of Children’s National Hospital, for an on-stage discussion about the power of collaboration to spur innovation.

That collaboration was on display as Dr. Newman and Richter shared details of the recently announced JLABS @ Washington, DC, a 32,000 square-foot facility to be located at the new Children’s National Research & Innovation Campus on the former Walter Reed Army Medical Center campus in the nation’s capital.

“We had this idea at Children’s National to develop the first pediatric research and innovation campus in the world to create a sustainable pipeline and ecosystem of everything needed to bring medical devices from concept to market for children. Seeing what Johnson & Johnson has accomplished with JLABS across the world, we knew they were the right partner,” said Dr. Newman.

Richter highlighted the need to take action, “We have made modest progress in pediatric device innovation, but we need to do better. We need to advance solutions that take into account the unique characteristics of our youngest and most vulnerable of patients. Only then will we achieve real progress for children and their families.” Of all the medical devices approved each year, only 25% are approved for children and most of those are approved for patients over the age of 18. Richter encouraged symposium attendees to leverage collaborations and convenings to move pediatric device development forward and lauded innovators focused on babies and children, calling them “super heroes.”

$150K medical device pitch competition

Six innovations that address the significant unmet needs of neonatal intensive care unit (NICU) patients were awarded a total of $150K during the medical device pitch competition at the 7th Annual Pediatric Device Innovation Symposium hosted by Children’s National Hospital at Boston Convention & Exhibition Center. From L to R are: Anthony Sandler, M.D., Children’s National Hospital; Neil Ray, Raydiant Oximetry; Julia Finkel, M.D., AlgometRx, Inc.; Eric Chehab, Ph.D., Novonate; Xina Quan, Ph.D., PyrAmes, Inc.; Mark Lehmkuhle, Epitel, Inc.; Adam Zysk, Ph.D., Rhaeos, Inc.; and Kolaleh Eskandanian, Ph.D., Children’s National Hospital.

Six winners were announced in the symposium’s $150,000 “Make Your Medical Device Pitch for Kids!” competition, sponsored by the National Capital Consortium for Pediatric Device Innovation (NCC-PDI) and focused on NICU devices, which the FDA identifies as an area of significant need for innovation. Ten finalists presented their innovations for a panel of 25 expert judges. Each winner receives a $25,000 award and an opportunity to participate in a first-of-its-kind pediatric accelerator program led by MedTech Innovator.

The winning pediatric devices and companies are:

AlgometRx, Inc., Washington, D.C. – The AlgometRx Rapid Drug Test is used to detect and monitor neonatal abstinence syndrome, allowing for earlier assessment and intervention of opioid withdrawal to reduce physiological stress.
Epitel, Salt Lake City, Utah – Epilog is an inexpensive, discrete and disposable EEG machine that provides real-time monitoring to revolutionize the way neonates suspected of hypoxic-ischemic encephalopathy are managed at community hospitals.
Novonate, South San Francisco, Calif. – LifeBubble secures and protects the umbilical catheter insertion site for neonates in intensive care, preventing infection from caregivers and parents.
PyrAmes Inc., Cupertino, Calif. – Noninvasive and wireless, the Boppli Band allows for risk- and pain-free continuous blood pressure monitoring for neonates.
Raydiant Oximetry, Mountain View, Calif. – Raydiant Oximetry Sensing Systems is a novel, non-invasive technology that more accurately detects fetal distress during labor and delivery, reducing medically unnecessary cesarean deliveries and the occurrence of newborns suffering the consequences of metabolic acidosis.
Rhaeos, Inc., Evanston, Ill. – FlowSense is a wearable device that enables noninvasive monitoring of ventricular shunt function in patients who have hydrocephalus, obviating the need for imaging and unnecessary hospital visits and admissions.

“Improved neonatal monitoring devices, such as those among our award winners, can make a critical difference in detecting interventions that could positively impact the long-term developmental trajectory of many children, said Kolaleh Eskandanian, Ph.D., M.B.A., P.M.P., vice president and chief innovation officer at Children’s National and principal investigator of NCC-PDI. “We welcome these winning companies into the NCC-PDI network of device startups and entrepreneurs and look forward to helping them accelerate commercialization so that these innovations can benefit children everywhere as soon as possible.”

Children’s National anesthesiologist and innovator Julia Finkel, M.D., delivers a winning pitch for her AlgometRx device for detecting and monitoring neonatal abstinence syndrome.

Award-winner AlgometRx is a spinout company from Children’s National Hospital that was founded by anesthesiologist and pain medicine research chief Julia Finkel, M.D. A non-invasive, handheld and portable device, AlgometRx captures a digital image of a patient’s pupillary light response and applies a series of propriety algorithms to measure pain type, intensity and drug effects in real time. Designed for use in virtually any clinical setting, Dr. Finkel originally developed this objective pain measurement technology to aid in diagnosing and monitoring non-verbal pediatric patients such as neonates. AlgometRx was also selected earlier this year to join the JLABS location in Philadelphia.

This is the ninth pediatric medical device competition sponsored by NCC-PDI, one of five FDA-funded programs focused on addressing unmet needs for pediatric medical devices. The consortium is led by the Sheikh Zayed Institute for Pediatric Surgical Innovation at Children’s National Hospital and the A. James Clark School of Engineering at the University of Maryland. NCC-PDI recently added new accelerators BioHealth Innovation and MedTech Innovator and design firm partner, Archimedic.

The symposium also featured four multidisciplinary panel discussions that followed the theme “Pediatric Device Clinical Trials: Forging a Better Path.” Solutions uncovered during these panels will be highlighted in an upcoming whitepaper that will be used to suggest FDA guidance on pediatric device trial conduct and best practices to safely validate medical devices for children more efficiently and effectively.

Vasum Peiris, M.D., chief medical officer, Pediatrics and Special Populations, Center for Devices and Radiological Health, FDA, gave the closing address, which outlined FDA initiatives focused on pediatric device development. David L. Wessel, M.D., senior vice president for the Center for Hospital-Based Specialties at Children’s National, provided an insightful overview of why NICU device development is so important and shared some of the NICU innovations currently in development at Children’s National, which ranks #1 nationally in NICU care.

Cardiac surgery chief recognized for studies of surgery’s impacts on neurodevelopment

October 9, 2019

Dr. Jonas and research collaborator Nobuyuki Ishibashi in the laboratory.

Richard Jonas, M.D., is this year’s recipient of the Newburger-Bellinger Cardiac Neurodevelopmental Award in recognition of his lifelong research into understanding the impact of cardiac surgery on the growth and development of the brain. The award was established in 2013 by the Cardiac Neurodevelopmental Outcome Collaborative (CNOC) to honor Jane Newburger and David Bellinger, pioneers in research designed to understand and improve neurodevelopmental outcomes for children with heart disease.

At Children’s National, Dr. Jonas’ laboratory studies of neuroprotection have been conducted in conjunction with Dr. Vittorio Gallo, director of neuroscience research at Children’s National, and Dr. Nobuyuki Ishibashi, director of the cardiac surgery research laboratory. Their NIH-supported studies have investigated the impact of congenital heart disease and cardiopulmonary bypass on the development of the brain, with particular focus on impacts to white matter, in people with congenital heart disease.

Dr. Jonas’s focus on neurodevelopment after cardiac surgery has spanned his entire career in medicine, starting with early studies in the Harvard psychology department where he developed models of ischemic brain injury. He subsequently undertook a series of highly productive pre-clinical cardiopulmonary bypass studies at the National Magnet Laboratory at MIT. These studies suggested that some of the bypass techniques used at the time were suboptimal. The findings helped spur a series of retrospective clinical studies and subsequently several prospective randomized clinical trials at Boston Children’s Hospital examining the neurodevelopmental consequences of various bypass techniques. These studies were conducted by Dr. Jonas and others, in collaboration with Dr. Jane Newburger and Dr. David Bellinger, for whom this award is named.

Dr. Jonas has been the chief of cardiac surgery and co-director of the Children’s National Heart Institute since 2004. He previously spent 20 years on staff at Children’s Hospital Boston including 10 years as department chief and as the William E. Ladd Chair of Surgery at Harvard Medical School.

As the recipient of the 2019 award, Dr. Jonas will deliver a keynote address at the 8^th Annual Scientific Sessions of the Cardiac Neurodevelopmental Outcome Collaborative in Toronto, Ontario, October 11-13, 2019.
