April 12, 2022

“This pitch competition helps to recognize and support the advancement of innovations that can specifically address the needs of pediatric patients,” says Kolaleh Eskandanian, Ph.D., M.B.A., P.M.P., vice president and chief innovation officer at Children’s National Hospital and principal investigator of NCC-PDI.

Recognizing the continued gap in the development and commercialization of medical devices for children versus adults, the National Capital Consortium for Pediatric Device Innovation (NCC-PDI), in collaboration with MedTech Innovator, is accepting applications through April 22, 2022, for its annual “Make Your Medical Device Pitch for Kids!” competition. Recognizing the wide range of unmet needs for diagnostic and therapeutic devices designed especially for children, this year’s competition is open to any innovation in medical technology that addresses a significant unmet need in pediatric medical care.

“As one of the five FDA Pediatric Device Consortia, NCC-PDI is focused on seeking out and addressing significant unmet needs in pediatric medical technology,” says Kolaleh Eskandanian, Ph.D., M.B.A., P.M.P., vice president and chief innovation officer at Children’s National Hospital and principal investigator of NCC-PDI. “While great advances are made in adult medical devices, children are often left behind because the pediatric market is small and there are not incentives to develop for pediatrics. This pitch competition helps to recognize and support the advancement of innovations that can specifically address the needs of pediatric patients.”

Using a virtual format, semi-finalists chosen from all submissions will make their first pitch on May 20, 2022. Up to six finalists selected from this first round will earn participation in a special pediatric-focused track of the MedTech Innovator accelerator program, the largest medical device accelerator in the world, beginning in June 2022. These innovators will then participate in the competition finals in the fall 2022 where judges will award up to $150,000 in FDA-sponsored grants to the devices selected as most impactful and commercially viable.

Unlike devices for adults, the development and commercialization of pediatric medical devices lags behind by approximately five to 10 years. Programs like the NCC-PDI pitch competition and MedTech Innovator accelerator program offer innovators access to expert insight and consultation to help overcome regulatory hurdles and advance the product’s development path.

NCC-PDI is one of five members in the FDA’s Pediatric Device Consortia Grant Program created to support the development and commercialization of medical devices for children. NCC-PDI is led by the Sheikh Zayed Institute for Pediatric Surgical Innovation at Children’s National and the A. James Clark School of Engineering at the University of Maryland with support from partners MedTech Innovator, BioHealth Innovation and design firm Archimedic.

Eskandanian adds that supporting the progress of pediatric innovators is a key focus of the new Children’s National Research & Innovation Campus, a one-of-its-kind ecosystem that drives discoveries that save and improve the lives of children. On a nearly 12-acre portion of the former, historic Walter Reed Army Medical Center in Northwest Washington, D.C., Children’s National has combined its strengths with those of public and private partners, including industry, universities, federal agencies, start-up companies and academic medical centers. The campus provides a rich environment of public and private partners which, like the NCC-PDI network, will help bolster pediatric innovation and commercialization.

Applications for the “Make Your Medical Device Pitch for Kids!” competition are open now through April 22 for innovations that address unmet pediatric needs.

Pediatric medical device competition takes aim at congenital heart disease

December 13, 2021

Consistent with its mission of addressing the most pressing pediatric device needs, this year’s competition focused on innovations in electrophysiology devices that monitor and treat congenital heart disease (CHD) and arrhythmias in pediatric patients.

The National Capital Consortium for Pediatric Device Innovation (NCC-PDI) announces five awardees chosen in its prestigious annual “Make Your Medical Device Pitch for Kids!” competition to share $150,000 in grant funding from the U.S. Food and Drug Administration (FDA) to support the advancement of pediatric medical devices. In an unprecedented decision, the competition judges determined that all five finalists were deserving of a grant award and recognition for the potential patient benefit and commercial viability of their innovations.

Consistent with its mission of addressing the most pressing pediatric device needs, this year’s competition, conducted by NCC-PDI partner MedTech Innovator, focused on innovations in electrophysiology devices that monitor and treat congenital heart disease (CHD) and arrhythmias in pediatric patients. The virtual pediatric pitch event was part of the 9^th Annual Symposium on Pediatric Device Innovation.

This year’s pediatric device innovation awardees are:

PeriCor – The Children’s Hospital at Montefiore – New York, NY, and Children’s National Hospital – PeriTorq, a catheter grip tool for use during pediatric cardiac interventional procedures;
Inkspace Imaging – Pleasanton, CA – a pediatric cardiac and vascular MRI coil;
Karios Technologies – Charlottesville, VA – Tissue Shield, a technology to prevent scar tissue formation (adhesions) on the heart after surgery;
Sibel – Niles, IL – ANNE One, ICU-grade wireless sensors for cardiopulmonary monitoring in neonates with congenital heart defects;
Starlight Cardiovascular – San Diego, CA – Project Lifeline, a less-invasive way to maintain sufficient circulation in newborns with ductal-dependent circulation that increases safety, procedural success and ease of use.

Congenital heart disease (CHD) affects six out of 1,000 babies born in the U.S. each year and is often complicated by arrhythmias, a condition where the heart beats too rapidly, too slowly or irregularly due to a misfiring of the body’s electrical impulses. While the last decade brought great advances in technologies that improve the care of adult arrhythmias, pediatric patients have been left behind, with only five devices approved for use in children in the same period. As a result, pediatric specialists are often using off-label or improvised devices to treat pediatric arrhythmias, including in the smallest newborns.

“Recognizing this unmet need, NCC-PDI opened the challenge earlier this year to select companies to enter MedTech Innovator’s pediatric accelerator program, made possible by NCC-PDI. The five companies have immensely benefited from the accelerator program and are well-positioned to compete for funding. They have the potential to advance pediatric health and provide a greater standard of care for children living with CHD,” says Kolaleh Eskandanian, Ph.D., M.B.A, P.M.P, vice president and chief innovation officer at Children’s National Hospital and principal investigator of NCC-PDI. “For too long, the unique needs of children have been overlooked in pediatric device development. Thanks to the support of the FDA, we are able to build our challenge competitions around the direst unmet needs, which are determined through a thorough needs assessment and market analysis conducted to inform each request for proposal. The funding incentivizes pediatric innovation and helps more companies navigate the path to commercialization.”

NCC-PDI is one of five consortia in the FDA’s Pediatric Device Consortia Grant Program created to support the development and commercialization of medical devices for children, which lags significantly behind the progress of adult medical devices. NCC-PDI 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, with support from partners MedTech Innovator, BioHealth Innovation and design firm Archimedic.

A pediatric accelerator program, powered by MedTech Innovator, is the consortium’s latest addition to a network of resources and experts that NCC-PDI provides in support of pediatric innovators. All five of this year’s competition finalists had an opportunity to participate in the year-long accelerator program.

Eskandanian adds that supporting the progress of pediatric innovators is a key focus of the new Children’s National Research & Innovation Campus, a one-of-its-kind ecosystem that drives discoveries that save and improve the lives of children. On a nearly 12-acre portion of the former, historic Walter Reed Army Medical Center in Northwest Washington, D.C., Children’s National has combined its strengths with those of public and private partners, including industry, universities, federal agencies, start-up companies and academic medical centers, the campus provides a rich environment of public and private partners which, like the NCC-PDI network, will help bolster pediatric innovation and commercialization.

Alternative synthetic compound might offer safer solution to children’s health

July 21, 2021

Not only is bisphenol A (BPA) added to medical equipment used to treat patients, it can also be found in 60% of neonatal intensive care unit (NICU) supplies, such as bandages and items for feeding, suggesting that occupational and clinical environments have a higher exposure to this synthetic compound.

Researchers at Children’s National Hospital found that a commonly used plastic, known as bisphenol S (BPS), was the least disruptive to cardiac electrophysiology and may serve as a safer chemical alternative for plastic medical devices used to treat vulnerable populations compared to other compounds, according to a new preclinical study published in Toxicological Sciences.

For decades, the medical device industry has used bisphenol chemicals known to antagonize ion channels, impair electrical conduction and trigger arrhythmias that affect the overall cardiovascular health in children. Not only is bisphenol A (BPA) added to medical equipment used to treat patients, it can also be found in 60% of neonatal intensive care unit (NICU) supplies, such as bandages and items for feeding, suggesting that occupational and clinical environments have a higher exposure to this synthetic compound.

Yet, very little is known about the downstream impact of BPA, BPS or bisphenol F (BPF) exposure on cardiac physiology.

To shed light on the safety profile of BPA and its alternatives BPS and BPF in plastic medical devices, Children’s National researchers present the first study that compares the acute effects of these three chemicals on cardiac electrophysiology in a preclinical model.

According to the researchers, children should continue receiving medical care to treat their condition.

“It is important to investigate iatrogenic plastic chemical exposures in young patients, as biomonitoring studies have reported elevated chemical exposures in NICU and pediatric intensive care unit patients,” said Devon Guerrelli, M.S., a Ph.D. candidate at Children’s National. “Our lab is actively working with cardiac surgeons to investigate patient exposure to both BPA and phthalate plasticizer chemicals. Patients and their parents can rest assured that our team’s priority is safety and advancement of the field.”

Future studies are needed to fully understand the chemicals’ safety on cardiac electrical and mechanical function due to notable biological differences between humans and preclinical models. The researchers call for the scientific community to explore the impact of these compounds on other organ systems by comprehensively assessing intracellular targets, genomic and proteomic expression profiles.

While health concerns remain, there is no consensus among the scientific community on the potential use of safer compound alternatives in pediatric plastic medical devices.

“First, a variety of preclinical models have been used by the scientific community to assess BPA toxicity. But, there is considerable variability between these different models, including differences in ion channel expression, which may produce conflicting results and limit extrapolation of the data to humans,” said Nikki Posnack, Ph.D., principal investigator at Children’s National Sheikh Zayed Institute for Pediatric Surgical Innovation and senior author. “Accordingly, in the presented study, we tested the effects of bisphenol chemicals using three different preclinical models. Second, studies assessing the safety profile of new structural analogs to BPA are limited.”

The researchers compared the cardiac safety profile of BPA, BPS and BPF by using a whole-cell voltage clamping recording on cell lines to study voltage-gated channels Nav1.5, Cav 1.2 and hERG, allowing the measurements of the cell’s electrical properties and total current through all the channels on a membrane in non-human subjects and cardiomyocytes human cell lines. Results of the study found that BPA was the most potent inhibitor of sodium, calcium and potassium channel currents compared to the alternatives BPS and BPF. BPA and BPF exposure also slowed atrioventricular conduction and increased atrioventricular nodal refractoriness.

“Based on our findings, acute exposure to high concentrations of BPA could lead to changes in cardiac electrophysiology,” said Tomas Prudencio, M.S., a research technician at Children’s National and lead author. “This includes slowing of electrical conduction from the atria to the ventricles, which would present as a prolongation of the PR interval in an electrocardiogram.”

Commercialization of novel facial analysis technology can improve diagnosis of rare disorders in pediatric patients

July 14, 2021

Children’s National Hospital has entered into a licensing agreement with MGeneRx Inc. for its patented pediatric medical device technology using objective digital biometric analysis software for the early and non-invasive screening of dysmorphic genetic diseases such as Noonan syndrome.

Children’s National Hospital has entered into a licensing agreement with life sciences technology company MGeneRx Inc. for its patented pediatric medical device technology using objective digital biometric analysis software for the early and non-invasive screening of dysmorphic genetic diseases. The technology, developed by a multidisciplinary Children’s National team led by Marius George Linguraru, D.Phil, M.A., M.Sc., of the Sheikh Zayed Institute for Pediatric Surgical Innovation and Marshall Summar, M.D., director of the Children’s National Rare Disease Institute (CNRDI), can provide a more advanced diagnostic tool for regions of the world with limited access to geneticists or genetic testing.

The application utilizes artificial intelligence (AI) and machine learning to analyze biometric data and identify facial markers that are indicative of genetic disorders. Physicians can capture biometric data points of a child’s face in real time within the platform, where it scans facial biometric features to determine the potential presence of a genetic disease, which can often be life-threatening without early intervention. Research studies conducted in conjunction with the National Human Genome Research Institute at the National Institutes of Health further enhanced the development of the application in recent years, showing the potential to detect, with a 90 percent accuracy, early diagnosis of 128 genetic diseases across pediatric subjects in 28 countries. These diseases include DiGeorge syndrome (22q11.2 deletion syndrome), Down syndrome, Noonan syndrome and Williams-Beuren syndrome.

“We are delighted to enter into this licensing agreement through Innovation Ventures, the commercialization arm of Children’s National Hospital, which seeks to move inventions and discoveries from Children’s National to the marketplace to benefit the health and well-being of children. Our mission is to add the ‘D’ in development to the ‘R’ in research to accelerate the commercialization of our intellectual property,” says Kolaleh Eskandanian, Ph.D., M.B.A., P.M.P., vice president and chief innovation officer at Children’s National and managing director of Innovation Ventures. “It is through partnerships with startups and the industry that we can achieve this goal and thus we highly value this new partnership with MGeneRx Inc. The acceleration and commercialization of this objective digital biometric analysis technology will not only help diagnose rare genetic disorders – it will also allow for earlier interventions that improve the quality of life for the children living with these conditions.”

Eskandanian adds that the social impact of this technology is especially profound in lower income nations around the world, where there is a high prevalence of rare genetic conditions but a severe lack in the specialty care required to diagnose and treat them. Additional data collected through the expanded use of the technology will help to further develop the application and expand its capabilities to identify and diagnose additional rare genetic conditions.

The licensing agreement was arranged by the Children’s National Office of Innovation Ventures, which is focused on the commercialization of impactful new pediatric medical device technologies and therapies to advance children’s health care. Created to catalyze the ongoing translational research of the Children’s National Research Institute (CNRI) as well as inventions by hospital’s clinicians, Innovation Ventures focuses on four core pillars to advance pediatric medical technologies including a Biodesign program, partnerships and alliances to augment internal capacity, seed funding to de-risk technologies and validate market and clinical relevance, and back-office operations to manage intellectual property and licensing activities. Since 2017, Children’s National intellectual property has served as the basis for over 15 licensing or option agreements with commercial partners.

Providing access to an array of experts and resources for pediatric innovators is one of the aims of the Children’s National Research & Innovation Campus, a first-of-its-kind focused on pediatric health care innovation, with the first phase currently open on the former Walter Reed Army Medical Center campus in Washington, D.C. With its proximity to federal research institutions and agencies, universities, academic research centers, as well as on-site incubator Johnson and Johnson Innovation – JLABS, the campus provides a rich ecosystem of public and private partners, which will help bolster pediatric innovation and commercialization.

Medical device pitch competition focuses on pediatric electrophysiology devices for CHD

How significant is the need for pediatric devices to address arrhythmias? In a recent survey of members conducted by the Pediatric and Congenital Electrophysiology Society (PACES), the vast majority (96%) said they believe there is a deficiency in devices available to serve the needs of pediatric patients. Conducted with the U.S.FDA, the survey also asked respondents to identify the biggest unmet need, which physicians identified as cardiovascular implantable electronic devices that are smaller, have better battery life and have pediatric-specific algorithms. Specifically, a leadless pacemaker designed for pediatric care was consistently on the most-wanted list.

FDA approves MR-HIFU system to treat osteoid osteoma

January 25, 2021

“This FDA approval encourages and further motivates our focused ultrasound program to continue to develop and expand clinical applications of MR-HIFU in the pediatric population,” said Karun Sharma, M.D., Ph.D.

After garnering successful clinical trial results at Children’s National Hospital, the United States Food and Drug Administration (FDA) recently announced the approval of Profound Medical’s Sonalleve MR-guided High Intensity Focused Ultrasound (MR-HIFU) system for the treatment of osteoid osteoma (OO) in the extremities. OO is a benign, but painful bone tumor that occurs most commonly in children and young adults. This marks the first focused ultrasound regulatory approval that will directly impact pediatric patients and it is the sixth indication to earn approval in the United States.

Nine patients were treated in a pilot trial designed to evaluate the safety and feasibility of MR-HIFU ablation treatment in patients with painful OO. The procedure was performed without any technical difficulties or serious adverse events in all nine patients, and resulted in complete pain relief with no further pain medication usage in eight out of nine patients.

“This FDA approval encourages and further motivates our focused ultrasound program to continue to develop and expand clinical applications of MR-HIFU in the pediatric population,” said Karun Sharma, M.D., Ph.D., director of Interventional Radiology and associate director of clinical translation at the Sheikh Zayed Institute for Pediatric Surgical Innovation (SZI) at Children’s National. “This completely non-invasive and radiation-free aspects of this therapy are especially relevant for growing children.”

Researchers at Children’s National have moved beyond OO are also evaluating MR-HIFU treatment for patients with relapsed and refractory bone and soft tissue tumors. “This is especially important as these patients don’t have any other good treatment options,” said Dr. Sharma. “For these tumors, we are using not only thermal ablation, but also other modes and biomechanisms of focused ultrasound such as mild hyperthermia to facilitate targeted, enhanced drug delivery and histotripsy (i.e., mechanical tissue fractionation) to enhance cancer immunotherapy. We also hope to move into MR-HIFU brain application in pediatrics.”

At Children’s National, a multidisciplinary team of physicians and scientists use MR-HIFU to focus an ultrasound beam into lesions to heat and destroy the tissue in that region, with no incisions at all. In 2015, Children’s National doctors became the first in the U.S. to use MR-HIFU to treat pediatric osteoid osteoma. The trial, led by Dr. Sharma, demonstrated early success in establishing the safety and feasibility of noninvasive MR-HIFU in children as an alternative to the current, more invasive approaches to treat these tumors. Since then, the Children’s National team has built an active clinical trials program and become a leader in translation of focused ultrasound for the treatment of relapsed pediatric solid tumors.

Top AI models unveiled in COVID-19 challenge to improve lung diagnostics

January 12, 2021

Coronavirus and lungs with world map in the background

The top 10 results have been unveiled in the first-of-its-kind COVID-19 Lung CT Lesion Segmentation Grand Challenge, a groundbreaking research competition focused on developing artificial intelligence (AI) models to help in the visualization and measurement of COVID specific lesions in the lungs of infected patients, potentially facilitating more timely and patient-specific medical interventions.

Attracting more than 1,000 global participants, the competition was presented by the Sheikh Zayed Institute for Pediatric Surgical Innovation at Children’s National Hospital in collaboration with leading AI technology company NVIDIA and the National Institutes of Health (NIH). The competition’s AI models utilized a multi-institutional, multi-national data set provided by public datasets from The Cancer Imaging Archive (National Cancer Institute), NIH and the University of Arkansas, that originated from patients of different ages, genders and with variable disease severity. NVIDIA provided GPUs to the top five winners as prizes, as well as supported the selection and judging process.

“Improving COVID-19 treatment starts with a clearer understanding of the patient’s disease state. However, a prior lack of global data collaboration limited clinicians in their ability to quickly and effectively understand disease severity across both adult and pediatric patients,” says Marius George Linguraru, D.Phil., M.A., M.Sc., principal investigator at the Sheikh Zayed Institute for Pediatric Surgical Innovation at Children’s National, who led the Grand Challenge initiative. “By harnessing the power of AI through quantitative imaging and machine learning, these discoveries are helping clinicians better understand COVID-19 disease severity and potentially stratify and triage into appropriate treatment protocols at different stages of the disease.”

The top 10 AI algorithms were identified from a highly competitive field of participants who tested the data in November and December 2020. The results were unveiled on Jan. 11, 2021, in a virtual symposium, hosted by Children’s National, that featured presentations from top teams, event organizers and clinicians.

Developers of the 10 top AI models from the COVID-19 Lung CT Lesion Segmentation Grand Challenge are:

Shishuai Hu, et al. Northwestern Polytechnical University, China. “Semi-supervised Method for COVID-19 Lung CT Lesion Segmentation”
Fabian Isensee, et al. German Cancer Research Center, Germany. “nnU-Net for Covid Segmentation”
Claire Tang, Lynbrook High School, USA. “Automated Ensemble Modeling for COVID-19 CT Lesion Segmentation”

Bruno Oliveira, et al. 2Ai – Polytechnic Institute of Cávado and Ave, Portugal. “Automatic COVID-19 Detection and Segmentation from Lung Computed Tomography (CT) Images Using 3D Cascade U-net”

Linguraru added that, in addition to an award for the top five AI models, these winning algorithms are now available to partner with clinical institutions across the globe to further evaluate how these quantitative imaging and machine learning methods may potentially impact global public health.

“Quality annotations are a limiting factor in the development of useful AI models,” said Mona Flores, M.D., global head of Medical AI, NVIDIA. “Using the NVIDIA COVID lesion segmentation model available on our NGC software hub, we were able to quickly label the NIH dataset, allowing radiologists to do precise annotations in record time.”

“I applaud the computer science, data science and image processing global academic community for rapidly teaming up to combine multi-disciplinary expertise towards development of potential automated and multi-parametric tools to better study and address the myriad of unmet clinical needs created by the pandemic,” said Bradford Wood, M.D., director, NIH Center for Interventional Oncology and chief, Interventional Radiology Section, NIH Clinical Center. “Thank you to each team for locking arms towards a common cause that unites the scientific community in these challenging times.”

Children’s National pain expert and innovator shares global summit spotlight

December 14, 2020

As a Johnson & Johnson Innovation Quickfire Children’s Challenge awardee, Dr. Finkel and AlgometRx will be among the first group of startups taking up residence at the new JLABS @ Washington, DC, located on the Children’s National Research & Innovation Campus, when it opens in 2021 at the historic former Walter Reed Army Medical Center site.

Medical technology innovator Julia Finkel, M.D., principal investigator for the Pain Medicine Initiative of the Sheikh Zayed Institute for Pediatric Surgical Innovation at Children’s National Hospital, recently participated in Galen Growth’s 2020 Global Healthtech Summit on a virtual panel featuring resident companies from Johnson & Johnson Innovation – JLABS who are utilizing artificial intelligence (AI) with the aim to create advanced solutions for diagnostics, treatment and clinical trials. The summit, hosted in Singapore, brought the innovators together to discuss their views on their progress, the challenges and opportunities for bringing medtech innovations to market in the current climate, as well as the tools needed to succeed.

Dr. Finkel’s innovation, AlgometRx, is a real-time pain measurement technology that captures a digital image of a patient’s pupillary response to a non-invasive stimulus and applies proprietary algorithms to measure pain type and intensity. AlgometRx, a spin-off of Children’s National, recently received a JLABS @Washington DC Quickfire Children’s Challenge award.

Joining Dr. Finkel on the panel were JLABS resident company leaders Don Crawford, CEO, Analytics 4 Life; Jim Havelka, CEO, Inform AI; and Kim Walpole, CEO, Trials.ai, which leverages AI to help research teams design more effective clinical trials. The 50-minute program, moderated by Kara Bortone, senior director, Portfolio and Sourcing Management, Johnson & Johnson Innovation – JLABS, focused on topics such as how these startups approached the market and regulatory processes as well as the up-and-coming trends in health technology.

A pediatric anesthesiologist, Dr. Finkel explained the significance of achieving real-time, objective pain measurement. “Pain is one word that represents a myriad of conditions,” she says. “Pain from acute post-operative conditions is very different from peripheral neuropathic pain and different from the type of inflammatory pain seen in lupus and rheumatoid arthritis. Being able to discern the drivers of pain, the etiology, is essential to treating it well and to developing better therapeutics in the future.”

Dr. Finkel points out that AlgometRx measures nociception, which is pain fiber activation, and that is also what medications are addressing. “We’re not discounting a patient’s perception of pain, as we recognize that one’s experience of pain is very complex,” she says. “What we aim to measure is the activity being transmitted by the pain nerve and the type of nerve fiber that is doing the transmitting.”

Aiming to identify pain phenotypes is an important part of current AlgometRx development work, says Dr. Finkel, as it could significantly aid clinical decision-making in treating and monitoring patients’ pain. The company’s current regulatory focus is to seek FDA clearance related to its potential use for patients with peripheral neuropathy, which is pain and numbness resulting from damage to the nerves outside of the brain and spinal cord. The company has also identified fibromyalgia cases as a place where the technology could potentially benefit a large number of patients as it considers regulatory clearance targets.

As the COVID-19 pandemic presented many unique challenges to healthcare startups this year, panel participants were asked to discuss the hurdles they faced and how it impacted device development.

Dr. Finkel notes that the pandemic slowed patient enrollment in AlgometRx clinical studies, but also presented some upside. “At first, that had a negative impact, but it wound up being a good thing,” she says. “It gave us a moment to pause, regroup and examine the data we’d already generated. That break gave us improved information and a new, more powerful approach. It changed our trajectory by altering our regulatory path in terms of the order of things in our pipeline, so we’ve been enormously productive.”

As a Johnson & Johnson Innovation Quickfire Children’s Challenge awardee, Dr. Finkel and AlgometRx will be among the first group of startups taking up residence at the new JLABS @ Washington, DC, located on the Children’s National Research & Innovation Campus, when it opens in 2021 at the historic former Walter Reed Army Medical Center site. Along with a one-year residency at the new JLABS @ Washington DC facility,* AlgometRx will receive mentorship from experts at the Johnson & Johnson Family of Companies and grant funding to help support its continued advancement to commercialization.

*Residency at JLABS @ Washington subject to acceptance and execution of a License Agreement with Children’s National.

NIH grant funds development of pediatric feeding tube placement device

December 9, 2020

A new grant will help to finalize development of the Pediatric PUMA-G System, the world’s first and only ultrasound-based procedure for placing feeding tubes into the stomach.

Researchers at Children’s National Hospital have received grant funding from the National Institute of Diabetes and Digestive and Kidney Diseases, within the National Institutes of Health (NIH), to finalize development of the Pediatric PUMA-G System, the world’s first and only ultrasound-based procedure for placing feeding tubes into the stomach. The funding will also support the first clinical trial of this technology in pediatric patients.

“Children’s National was chosen because we have a strong record of innovating pediatric devices and surgical procedures through the Sheikh Zayed Institute and we have a busy clinical interventional radiology service,” says Karun Sharma, M.D., Ph.D., director of Interventional Radiology and associate director of clinical translation at the Sheikh Zayed Institute for Pediatric Surgical Innovation (SZI) at Children’s National. “We are proud to be a part of this collaboration that will potentially help improve care of pediatric patients who cannot tolerate feeding by mouth.”

The feeding tubes are vital for children who cannot eat or swallow and require liquid nutrition (known as enteral feeding). Common feeding tube placement procedures for children may expose them to risks from invasive surgical tools or from ionizing radiation, which may lead to cancer in young patients at elevated rates. The PUMA-G System is less invasive and uses ultrasound to help physicians image the body during the procedure.

The grant, totaling $1.6M, will clinically evaluate the Pediatric PUMA-G System in collaboration with CoapTech, a biotechnology medical device company and two other premier pediatric medical centers — New York-Presbyterian Morgan Stanley Children’s Hospital and Children’s Hospital of Philadelphia.

COVID-19: First comprehensive review of pediatric lung imaging features

October 19, 2020

A systematic review and meta-analysis by Children’s National Hospital researchers, published in Pediatric Pulmonology, provides the first comprehensive review of the findings of published studies describing COVID-19 lung imaging data in children.

The number COVID-19 studies focused on children have been small and with limited data. This has prevented the identification of specific pediatric lung disease patterns in COVID-19. Although children make up around 9.5% of COVID-19 infections, less than 2% of the literature on the virus, its symptoms and effects, have focused on kids.

A systematic review and meta-analysis by Children’s National Hospital researchers, published in Pediatric Pulmonology, provides the first comprehensive review of the findings of published studies describing COVID-19 lung imaging data in children. The analysis concludes that chest CT manifestations in children with COVID‐19 could potentially prompt intervention in the pediatric population.

Marius George Linguraru, D.Phil., M.A., M.Sc., principal investigator in the Sheikh Zayed Institute for Pediatric Surgical Innovation at Children’s National, discusses the importance of this work.

Q: What findings stand out to you?

A: We found that more than a third of children with COVID-19 had normal imaging. The lung imaging findings in these children were overall less frequent and less severe than in adult patients, but they were also more heterogeneous than in adults. Importantly, children with COVID-19 were three times more likely to have a normal exam than adults.

Several common lung imaging findings reported in adults were extremely rare or not found in the pediatric studies. These discoveries, and other recent reports in this space, support the fact that children’s symptoms may be less obvious than adults or even absent, but they still carry the virus and may be at risk for serious and life-threatening illness.

Q: How will the findings of this study benefit pediatric care?

A: In our study, we showed how the health of the lungs of these children is impacted. Our results from data from 1,026 children (from newborns to 18 year old) with COVID-19 present chest manifestations that could potentially prompt informed intervention and better recovery.

Another conclusion of our study is that the abnormalities reported on the chest scans of children infected with COVID-19 are distinct from the typical lung images seen during other viral respiratory infections in the pediatric population. This is important for preparing for the cold and flu season.

Q: Why was this review important to our understanding of how COVID-19 impacts children?

A: This is the first systematic review and meta-analysis focused on the manifestation of the COVID-19 infection in the lungs of children. Our study, and others from colleagues at Children’s National, helps lead the efforts on elucidating how the pandemic affects the health of children.

Though children were initially thought to be less susceptible to infection, the data has made it clear that many children are at high risk for hospitalization and severe health complications. Although there are similarities between how children and adults are affected by the pandemic, there are also critical differences.

Given the limited knowledge in the manifestation of COVID-19 in children, with children susceptible to infection and hospitalization, and with children returning to school, continued efforts to understand the impact of COVID-19 on young patients is critically important. Understanding how children fare through the pandemic is the foundation of discovering better ways to take care of young patients and their health.

Children’s National designated Center of Excellence by Focused Ultrasound Foundation

September 28, 2020

“This designation provides a high level of recognition and legitimacy to the work our Children’s National team has done with MR-HIFU over many years,” says Karun Sharma, M.D., PhD, director of Interventional Radiology and associate director of clinical translation at the Sheikh Zayed Institute for Pediatric Surgical Innovation.

More precise, less invasive and less painful surgery with lower risk of complications and no radiation exposure – these are some of the benefits of treating pediatric tumors with Magnetic Resonance Guided High Intensity Focused Ultrasound (MR-HIFU). And now the Focused Ultrasound Foundation has designated Children’s National Hospital as the first global pediatric Center of Excellence (COE) for using this technology to help patients with specific types of childhood tumors.

“This designation provides a high level of recognition and legitimacy to the work our Children’s National team has done with MR-HIFU over many years,” says Karun Sharma, M.D., PhD, director of Interventional Radiology and associate director of clinical translation at the Sheikh Zayed Institute for Pediatric Surgical Innovation (SZI) at Children’s National. “This will allow our focused ultrasound program to expand to other areas of interest and become more cohesive while continuing to uncover additional clinical indications for pediatric patients.”

At Children’s National, radiologists use MR-HIFU to focus an ultrasound beam into lesions, usually tumors of the bone and soft tissues, to heat and destroy the tissue in that region. There are no incisions at all. In 2015, Children’s National doctors became the first in the U.S. to use MR-HIFU to treat pediatric osteoid osteoma, a painful, but benign, bone tumor that commonly occurs in children and young adults. The trial, led by Dr. Sharma, demonstrated early success in establishing the safety and feasibility of noninvasive MR-HIFU in children as an alternative to the current, more invasive approaches to treat these tumors. The team also conducted another clinical trial, led by AeRang Kim, M.D., Ph.D., a pediatric oncologist, to treat relapsed soft tissue tumors such as sarcomas.

Since then, the Children’s National team has built an active clinical trials program and become a leader in translation of focused ultrasound for the treatment of pediatric solid tumors. The center is currently investigating the treatment of malignant solid tumors with focused ultrasound alone and combined with chemotherapy.

“Focused ultrasound offers a number of important benefits over traditional therapies, which are especially paramount for the pediatric population,” said Focused Ultrasound Foundation Chairman Neal F. Kassell, M.D. “The team at Children’s National has an exemplary track record in using this technology to pioneer new treatment options for their patients, and we look forward to collaborating and supporting their future research.”

As a designated COE, Children’s National has the necessary infrastructure to support the ongoing use of this technology, especially for carrying out future pediatric clinical trials. This infrastructure includes an ethics committee familiar with focused ultrasound, a robust clinical trials research support team, a data review committee for ongoing safety monitoring and annual safety reviews, and a scientific review committee for protocol evaluation.

The program also features a multidisciplinary team of clinicians and investigators from SZI, radiology, oncology, surgery and orthopedics. With the new designation and continued expansion, we will expand MR-HIFU to other areas such as neuro-oncology, neurosurgery, and urology. Ongoing and future work will investigate a rational combination of MR-HIFU with local tumor drug delivery, immunotherapy and cellular therapy.

“This recognition sets us apart as a premier pediatric institution, and will allow us to pave the way to make pediatric surgery more precise and less invasive,” says Dr. Sharma.

$1M grant funds research on quantitative imaging for tumors

July 21, 2020

“For children who are at risk of losing their vision, this project will bring a window of opportunity for physicians to start treatment earlier and save their vision,” says Marius George Linguraru, DPhil, MA, MSc.

A team from Children’s National Hospital is part of a project receiving a two-year grant of nearly $1,000,000 from the National Institutes of Health (NIH) for the first pediatric project in the Quantitative Imaging Network (QIN) of the National Cancer Institute (NCI). Marius George Linguraru, DPhil, MA, MSc, principal investigator from the Sheikh Zayed Institute for Pediatric Surgical Innovation at Children’s National Hospital in Washington, D.C., is one of two principal investigators on the project, which focuses on developing quantitative imaging (QI) tools to improve pediatric tumor measurement, risk predictions and treatment response. Roger Packer, M.D., Senior Vice President of the Center for Neuroscience & Behavioral Health, Director of the Gilbert Neurofibromatosis Institute and Director of the Brain Tumor Institute, is co-investigator.

The project, in collaboration with Children’s Hospital of Philadelphia and Children’s Hospital Colorado, centers on the most common type of brain tumor in children, called a low-grade glioma. This project focuses on a clinically challenging group of children with neurofibromatosis type 1 (NF1), the most common inherited tumor predisposition syndrome. Nearly 20% of children with NF1 will develop a low-grade glioma called optic pathway glioma (OPG). In children with this type of brain tumor, the growth occurs around the optic nerve, chiasm and tracts, also called the optic pathway, which connects the eye to the brain. OPGs can cause vision loss and even blindness. Permanent vision loss usually occurs between one and eight years of age with doctors closely monitoring the tumor with magnetic resonance imaging (MRI) to assess the disease progression.

“Our traditional two-dimensional measures of tumor size are not appropriate to assess the changes in these amorphous tumors over time or how the tumor responds to treatment,” says Linguraru. “This means physicians have difficulty determining the size of the tumor as well as when treatment is working. Research such as this can lead to innovative medical technologies that can improve and possibly change the fate of children’s lives.”

Dr. Linguraru is leading the technical trials on this project, which take place in the first two years, or phase one, starting in June 2020. Phase one focuses on improving the often inaccurate human measurements of tumor size by developing QI tools to make precise and automated measures of tumor volume and shape using machine learning. In this phase, the project will use and homogenize MRI data from multiple centers to develop predictive models of the treatment response based on the tumor volume that are agnostic to the differences in imaging protocols. By doing this, it will allow physicians to make more informed decisions about the treatment’s success and whether the child will recover their vision.

When phase one is complete, Linguraru and the project’s other principal investigator Robert A. Avery, DO, MSCE, neuro-ophthalmologist in the Division of Ophthalmology at Children’s Hospital of Philadelphia, will initiate the second phase, which includes validating the QI application on data from the first ever phase III clinical trial comparing two treatments for NF1-OPGs. Phase two is scheduled to start in the Summer 2022 and continue through Summer 2025.

“For children who are at risk of losing their vision, this project will bring a window of opportunity for physicians to start treatment earlier and save their vision,” says Linguraru. “For those children who won’t benefit from chemotherapy because the tumor poses no threat to their sight, this project will save them from having to go through that difficult treatment unnecessarily. It will be life-changing for the children and their families, which is what excites me about this QI application.”

This project is a collaboration between Children’s Hospital of Philadelphia and Children’s National Hospital in Washington, D.C., in partnership with Children’s Hospital of Colorado and University of Pennsylvania. Upon project completion, the QI application will provide a precision-medicine approach for NF1-OPGs and improve clinical outcomes for pediatric tumors.

NCC-PDI launches special pediatric medical device competition focused on covid-19 innovations

June 17, 2020

“Innovation in children’s medical devices consistently lags behind that of adults and we need to change that if we are to confront the challenge to children’s health of COVID-19 and future pandemics,” said Kolaleh Eskandanian, Ph.D., MBA, PMP, vice president and chief innovation officer at Children’s National Hospital and principal investigator of NCC-PDI.

As medical data increasingly highlights the serious impact of COVID-19 on children’s health, the National Capital Consortium for Pediatric Device Innovation (NCC-PDI) announces a special pitch competition focused on COVID-19-related pediatric medical devices that support home health monitoring and telehealth, and improve sustainability, resiliency and readiness in diagnosing and treating children during a pandemic.

The “Make Your Medical Device Pitch for Kids!” COVID19 edition is led by NCC-PDI co-founders 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 and powered by nonprofit accelerator and NCC-PDI member, MedTech Innovator. The finals in the virtual pitch event will be held on July 20, 2020. Winners will each receive a grant award of up to $50,000.

“Despite early reports that COVID-19 posed less of a threat to children, a recent study published by Children’s National shows that considerable numbers of pediatric patients are hospitalized and become critically ill from the disease,” said Kolaleh Eskandanian, Ph.D., MBA, PMP, vice president and chief innovation officer at Children’s National Hospital and principal investigator of NCC-PDI. “Innovation in children’s medical devices consistently lags behind that of adults and we need to change that if we are to confront the challenge to children’s health of COVID-19 and future pandemics.”

Funding for the competition is made possible by a grant from the Food and Drug Administration (FDA) and a philanthropic gift from Mei Xu, founder of e-commerce platform Yes She May, a site dedicated to women-owned brands.

Along with grant funding, one company from the competition will be selected by Johnson & Johnson Innovation – JLABS to receive a one-year residency at JLABS @ Washington, DC, which will be located on the new Children’s National Research & Innovation Campus currently under construction. In addition to the 2021 JLABS residency, the awardee will have access to the JLABS community and expert mentoring by the Johnson & Johnson family of companies.

Submissions for the competition are being accepted now through Monday, July 6, 2020z at the NCC-PDI website, Innovate4Kids.org, where complete details can be found.

NCC-PDI is one of five members in the FDA’s Pediatric Device Consortia Grant Program created to support the development and commercialization of medical devices for children, which lags significantly behind the progress of adult medical devices.

Up to 10 finalists chosen from that event will compete for up to $250,000 in grant awards in Toronto, Canada on October 4. Finalists also receive a spot in the MedTech Innovator 2020 Accelerator – Pediatric Track, which provides a customized curriculum and in-depth mentorship. Finalists will be announced in May, 2020.

This is the ninth competition in seven years hosted by NCC-PDI, one of five FDA Pediatric Device Consortia Grant Program members supporting the development and commercialization of pediatric medical devices. NCC-PDI 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. Additional consortium members include accelerators Medtech Innovator, BioHealth Innovation and design firm partner Archimedic.

“This year’s competition focuses on three medical device areas of critical need for pediatric patients, so we want to give innovators as much time as possible to prepare their submissions,” said Kolaleh Eskandanian, Ph.D., MBA, PMP, vice president and chief innovation officer at Children’s National Hospital and principal investigator of NCC-PDI . “Our goal is to support devices that will improve care for children by helping them advance on the pathway to commercialization. We have seen how this competition can provide significant momentum for pediatric innovations, so we want to encourage as much participation as possible.”

To date, NCC-PDI has mentored over 100 medical device sponsors to help advance their pediatric innovations, notes Eskandanian, with six devices having received either their FDA market clearance or CE marking. Along with the positive exposure of presenting at this competition, she notes that the success of NCC-PDI’s portfolio companies is attributed to funding, mentorship, support from partners and facilitated interactions between device innovators and potential investors.

Eskandanian notes that enhancing access to resources for pediatric innovators is one aim of the Children’s National Research & Innovation Campus, a first-of-its-kind campus focused on pediatric healthcare innovation, currently under development on the former Walter Reed Army Medical Center campus in Washington, D.C. With its proximity to federal research institutions and agencies, universities, academic research centers, as well as on site accelerator Johnson & Johnson Innovation – JLABS, the campus will create a rich ecosystem of public and private partners which, like the NCC-PDI network, will help bolster pediatric innovation and commercialization. Opening is scheduled for December 2020.

Premier annual pediatric medical device competition now accepting submissions

January 21, 2020

Pediatric innovators pitch for grant awards and participation in a special accelerator program.

The official call for submissions is underway for the premiere annual pediatric medical device competition, sponsored by National Capital Consortium for Pediatric Device Innovation (NCC-PDI). The competition is led by Sheikh Zayed Institute for Pediatric Surgical Innovation at Children’s National Hospital, the A. James Clark School of Engineering at the University of Maryland and non-profit accelerator MedTech Innovator. The three organizations are all an integral part of the FDA-funded NCC-PDI, which aims to facilitate the development, production and distribution of pediatric medical devices. Additional NCC-PDI members include accelerator BioHealth Innovation and design firm Archimedic.

The competition focuses on pediatric devices in three areas of critical need: cardiovascular, orthopedic and spine, and neonatal intensive care (NICU) and is now accepting applications. Contestants will pitch for a share of up to $250K in grant awards and the opportunity to participate in the MedTech Innovator 2020 Accelerator – Pediatric Track.

The first stage of competition will be held on March 23 at the University of Maryland and will include up to 30 companies selected from all submissions received. Up to 10 finalists selected from that event will move on to the “Make Your Medical Device Pitch for Kids!” finals on October 4, 2020 in Toronto, Canada. Finalists from the March qualifying round will be notified in May, 2020.

“While there is a great need for pediatric devices in many specialty areas, the development and commercialization process is very challenging because of the small market size and dynamic characteristics of the patient population,” says Kolaleh Eskandanian, Ph.D., MBA, PMP, vice president and chief innovation officer at Children’s National Hospital and principal investigator of NCC-PDI. “To provide pediatric innovators with greater support in meeting these unique challenges, we must go beyond grant funding, which is why we are collaborating with MedTech Innovator to offer an accelerator program with a pediatric track.”

To date, NCC-PDI has mentored over 100 medical device sponsors to help advance their pediatric innovations, notes Eskandanian, with six devices having received either their FDA market clearance or CE marking. She says the success of NCC-PDI’s portfolio companies is attributed to funding, mentorship, support from partners, facilitated interactions between device innovators and potential investors, and being discovered during their presentations at the signature “Make Your Medical Device Pitch for Kids!” competitions.

While advancements have been made in some pediatric specialties, there is still a critical need for novel devices in cardiovascular, orthopedic and spine, and NICU areas. On average over the past decade, only 24 percent of life-saving medical devices approved by FDA – those that go through PMA and HDE regulatory pathways – have an indication for pediatric use. Of those, most are designated for children age 12 or older. “Devices designed specifically for the younger pediatric population are vitally needed and, at this early stage of the intervention, can significantly improve developmental outcomes for a child,” Eskandanian said.

Enhancing access to resources for pediatric innovators is also one of the aims of the Children’s National Research and Innovation Campus, a first-of-its-kind focused on pediatric healthcare innovation, currently under development on the former Walter Reed Army Medical Center campus in Washington, D.C. and opening in December, 2020. With its proximity to federal research institutions and agencies, universities, academic research centers, as well as on site accelerator Johnson and Johnson Innovation – JLABS, the campus will create a rich ecosystem of public and private partners which, like the NCC-PDI network, will help bolster pediatric innovation and commercialization.

NOTE: The deadline for submissions has been extended to February 22 at midnight EST.

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.

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.

Plasticizer interaction with the heart

July 24, 2019

Calling an ambulance during an emergency, emailing a journal article before a 5 p.m. deadline and maintaining conditions during the fifth week of a 6-week lab study, without altering the light or temperature, requires electricity and translates into time, money and lives saved. During critical moments, we appreciate the tiny particles and ions in electric currents that power our phones, computers or laboratory equipment. We seldom think about the speed of these connections or potential disruptors when conditions are stable. The same applies to the electric currents, or electrophysiology, of our heart.

Arrhythmias affect millions of Americans but can be controlled with routine screenings and preventive care. In an intensive care setting, helping a patient maintain a steady heart rate, especially if they are at risk for cardiac complications, may support a faster recovery, shorter hospital stay, reduced health care costs and improved health outcomes, such as avoiding complications from heart failure or stroke.

A preclinical study, entitled “Plasticizer Interaction With the Heart,” appears in the July issue of Circulation: Arrhythmia and Electrophysiology and examines the role plastic exposure, akin to exposure in a medical setting, has on heart rhythm disruptions and arrhythmias.

New preclinical research finds acute exposure to MEHP, a common plasticizer used in medical equipment, increases risk for alternans and arrhythmias, disruptions in heart rhythm. The images above show changes in heart rhythm, measured by slowed epicardial conduction velocity, enhanced action potential prolongation and impaired sinus node activity.

The research team, led by researchers at Children’s National Health System, discovered increased risks for irregular heart rhythms after exposing intact, in vitro heart models to 30 minutes of mono-2-ethylhexyl phthalate (MEHP), a metabolite from Di-2-ethylhexyl phthalate (DEHP). DEHP is a chemical commonly used to make plastics pliable in FDA-approved medical devices. This phthalate accounts for 40% of the weight of blood storage bags and up to 80% of the weight of tubes used in an intensive care setting, such as for assisted feeding or breathing, and for catheters used in diagnostics or to conduct minimally invasive cardiac procedures.

The team chose to study the heart’s reaction to 60 µM of MEHP, a level comparable to stored blood levels of MEHP observed in pediatric patients and in neonatal exchange transfusion procedures. They found 30-minute exposure to MEHP slowed atrioventricular conduction and increased the atrioventricular node effective refractory period. MEHP prolonged action potential duration time, enhanced action potential triangulation, increased the ventricular effective refractory period and slowed epicardial conduction velocity, which may be due to the inhibition of Nav 1.5, or sodium current.

“We chose to study the impact of MEHP exposure on cardiac electrophysiology at concentrations that are observed in an intensive care setting, since plastic medical products are known to leach these chemicals into a patient’s bloodstream,” says Nikki Gillum Posnack, Ph.D., a principal investigator with the Sheikh Zayed Institute for Pediatric Surgical Innovation at Children’s National and an assistant professor of pediatrics at the George Washington University School of Medicine and Health Sciences. “In critical conditions, a patient may have a blood transfusion, require extracorporeal membrane oxygenation, undergo cardiopulmonary bypass or require dialysis or intravenous fluid administration. All of these scenarios can lead to plastic chemical exposure. Our research team wants to investigate how these plastic chemicals can impact cardiac health.”

In this review, Dr. Posnack’s team mentions one reason for the observed changes in the preclinical heart models may be due to the structure of phthalates, which resemble hormones and can interfere with a variety of biological processes. Due to their low molecular weight, these chemicals can interact directly with ion channels, nuclear receptors and other cellular targets.

Existing epidemiological research shows associations between exposure to phthalates and adverse health outcomes, including metabolic disturbances, reproductive disorders, inflammatory conditions, neurological disorders and cardiovascular disease. This is the first study to examine the link between cardiac electrophysiology in intact hearts and exposure to MEHP, comparable to levels observed in an ICU.

Dr. Posnack’s team previously found DEHP reduced cellular electrical coupling in cardiomyocyte cell models, which slowed conduction velocity and produced an arrhythmogenic phenotype. A microarray analysis found heart cells treated with DEHP led to mRNA changes in genes responsible for contracting and calcium handling. Another preclinical study showed DEHP altered nervous system regulation of the cardiovascular system. Future studies to expand on this research may include the use of larger preclinical models or human assessments. For the latter, stem cell-derived cardiomyocytes can be used to compare the safety profile of plastic chemicals with potential alternatives.

An accompanying editorial, entitled “Shocking Aspects of Nonconductive Plastics,” authored by cardiology researchers at the University of Wisconsin-Madison, puts this novel research into perspective. Like Dr. Posnack, the team notes that while the clinical impact plasticizers have on heart health still needs to be determined, the work contributes to compelling data among multiple researchers and shows DEHP and MEHP are not inert substances.

“Toxic plasticizers in children’s toys and baby products hit public headlines 20 years ago, but exposure to these compounds is up to 25x higher in patients undergoing complex medical procedures,” write the University of Wisconsin-Madison researchers. “We readily (and unknowingly) administer these compounds, and at times in high quantity, to some of our most vulnerable patients. This work highlights the need for further investigation into short and long-term plasticizer exposure on cardiac electrophysiology.”

The Agency for Toxic Substances and Disease Registry (ATSDR), part of the Centers for Disease Control and Prevention (CDC), released a public health statement about DEHP in 2002, noting more research in humans is needed to issue formal warnings against this phthalate.

ATSDR states there is no conclusive evidence about the adverse health effects of children exposed to DEHP in a medical setting, such as procedures that require the use of flexible tubing to administer intravenous fluids or medication. However, the CDC statement includes limits of DEHP exposure, based on preclinical models, used to guide upper DEHP limits in consumer products, including food packaging, drinking water, and air quality in the workplace.

“It’s important to note that this was a preliminary study performed on an ex vivo model that is largely resilient to arrhythmias”, says Rafael Jaimes III, Ph.D., the first author of the study and a senior scientist at Children’s National. “Due to the nature of the design, it was somewhat alarming that we found such significant effects. I predict that electrophysiological disturbances will be more pronounced in models that more closely resemble humans. These types of models should absolutely be studied.”

“And, importantly, our results may incentivize the development and use of new products that are manufactured without phthalates,” Dr. Posnack adds.

These questions are powering Dr. Posnack and her team through a decade-long, multi-institution research investigation to understand how plastic chemicals and medical device biomaterials can impact cardiac health.

Marius George Linguraru, D.Phil., M.A., M.Sc., awarded Department of Defense grant for Neurofibromatosis application development

July 22, 2019

Marius George Linguraru, D.Phil., M.A., M.Sc., is a principal investigator in the Sheikh Zayed Institute for Pediatric Surgical Innovation at Children’s National, where he founded and directs the Precision Medical Imaging Laboratory. He’s an expert in quantitative imaging and artificial intelligence.

Marius George Linguraru, D.Phil., M.A., M.Sc., a principal investigator in the Sheikh Zayed Institute for Pediatric Surgical Innovation at Children’s National has been awarded a Congressionally Directed Medical Research Program (CDMRP) grant through the Department of Defense. This grant allows Dr. Linguraru to develop a novel quantitative MRI application that can inform treatment decisions by accurately identifying which children with Neurofibromatosis type 1 (NF1) and optic pathway glioma (OPG) are at risk of losing their vision.

This grant is part of the Neurofibromatosis Research Program of the CDMRP, which fills research gaps by funding high impact, high risk and high gain projects. Dr. Linguraru, who directs the Precision Medical Imaging Laboratory in the Sheikh Zayed Institute, is collaborating with the Gilbert Family Neurofibromatosis Institute and the Children’s Hospital of Philadelphia on this project.

An expert in quantitative imaging and artificial intelligence, Dr. Linguraru has published several peer-reviewed studies on NF1 and OPG, a tumor that develops in 20 percent of children with NF1. The OPG tumor can cause irreversible vision loss, leading to permanent disability in about 50 percent of children with the tumor. This project, titled “MRI Volumetrics for Risk Stratification of Vision Loss in Optic Pathway Gliomas Secondary to NF1” will provide doctors certainty when identifying which children with NF1-OPG will lose vision and when the vision loss will occur.

Dr. Linguraru and his team will validate the quantitative MRI application that they’re developing by studying children at 25 NF1 clinics from around the world. Doctors using the application, which will perform comprehensive measurements of the OPG tumor’s volume, shape and texture, will upload their patient’s MRI into Dr. Linguraru’s application. Using recent advances in quantitative image analysis and machine learning, the application will then definitively determine whether the child’s NF1-OPG is going to cause vision loss and therefore requires treatment.

This diagnosis can occur before visual acuity starts to decline, which provides an opportunity for early treatment in children at risk for vision loss. Dr. Linguraru believes that early diagnosis and treatment can help to avoid lifelong visual impairment for these patients while preventing unnecessary MRIs and aggressive chemotherapy in pediatric patients who are not at risk of vision loss.

Occurring in one in 3,000 to 4,000 live births, NF1 is a genetic condition that manifests in early childhood and is characterized by changes in skin coloring and the growth of tumors along nerves in the skin, brain and other parts of the body. It is unknown why the OPG tumor caused by NF1 only results in vision loss for 50 percent of children. Some children will sustain lifelong disability from their vision loss, despite receiving treatment for their tumor, likely because treatment was started late. In other instances, doctors are unknowingly treating NF1-OPGs that would never cause vision loss.

Dr. Linguraru and his team have already proven that their computer-based, quantitative imaging measures are more objective and reliable than the current clinical measures, enabling doctors to make earlier and more accurate diagnoses and develop optimal treatment plans.

Understanding low cardiac output after surgery

July 5, 2019

Rafael Jaimes, Ph.D., created an algorithm that is being tested in a pre-clinical model to characterize the light absorbance spectrum from different heart regions using a spectrometer.

After intense cardiac surgery, sometimes a patient’s heart is unable to effectively deliver oxygenated blood and nutrients throughout the recovering body. Known as inadequate or low cardiac output, the condition occurs in about a quarter of patients following surgery with cardiopulmonary bypass, including young children who require complex procedures to correct congenital heart defects at Children’s National Health System.

Researchers at the Sheikh Zayed Institute for Pediatric Surgical Innovation are exploring several facets of this challenge, with the goal of better understanding post-operative recovery trajectories in pediatric patients. Rafael Jaimes, Ph.D., a staff scientist at the institute, leads this work to identify when and how low cardiac output occurs, pinpoint the physical hallmarks of this condition and use that information to prevent long term damage and complications after surgery, including cardiac arrest.

“More research needs to be done to understand the cause of this overarching and multi-faceted syndrome,” says Dr. Jaimes. “I’m interested in understanding how metabolic insufficiency contributes to this condition, and also exploring how we can use current imaging and diagnostic tools to measure, track and treat the insufficiencies that contribute to low cardiac output.”

Tracking inadequate oxygen and nutrient delivery to the parts of the heart that have been repaired is one avenue under exploration. Currently, a cardiac-specific real-time device to measure the oxygen state of the heart, while a patient is in post-operative critical care, is under development.

The heart’s complexity has made using current oxygen measurement devices, such as spectrometers, very difficult. To date no tool exists that effectively screens out artifacts and noise to allow clear visualization. However, during his post-doctoral work, Dr. Jaimes has created a new algorithm that may be the first of its kind to accomplish this feat.

This work on low cardiac output recently received a Congenital Heart Defect Research Award, which is a collaborative program of the Children’s Heart Foundation and the American Heart Association that supports innovative research, seeking to understand and treat congenital heart defects.

A new research study will build on his previous studies by using the algorithm to characterize the absorbance spectrum from different heart regions in a pre-clinical model. The data collected will serve as the baseline for development of a prototype spectrometer software, capable of tracking changes in heart oxygenation before, during and after surgery.

The end goal is to more effectively identify when parts of the heart are deprived of oxygen and nutrients and prevent resulting impacts on cardiac metabolism and output. Doing so will decrease short term mortality and morbidity and may also improve circulation systemically, potentially reducing long term health impacts of reduced oxygenation, such as neurodevelopmental disorders.
