Novel dye may improve outcomes for liver surgery

Researchers at Children’s National Hospital and the National Cancer Institute (NCI) have developed a novel, near‐infrared dye that can help surgeons identify structures and detect leakage during liver surgery, offering a promising tool that may someday improve outcomes for patients undergoing gastroenterology procedures.

The problem has vexed the medical community for some time: Despite advances in bile leak detection, only a third of bile duct injuries are found at the time of surgery, extending hospital stays and increasing the risk of liver failure, sepsis and even death.

Why we’re excited

The new dye – known as Bile Label Dye 760 (BL-760) – provided several promising advantages over existing surgical tools during non-clinical testing. When administered into the liver, BL‐760 was excreted and visible in bile ducts within minutes, without significant or prolonged impact on organ tissue. Its fluorescence against the surgical field also provided a superior view of leaks, offering an opportunity to treat the patient while still in the operating room. Details were published recently in Lasers in Surgery and Medicine.

“BL-760 is a promising option for monitoring the health of the liver during surgery, and we are excited to continue our testing and hopefully see first-in-human trials in the future,” said Richard Cha, Ph.D., principal investigator at the Sheikh Zayed Institute of Pediatric Surgical Innovation, part of the NIH-funded team that developed the dye.

The new dye – known as Bile Label Dye 760 (BL-760) – provided several promising advantages over existing surgical tools during non-clinical testing.

The big picture

The dye could significantly advance hepatobiliary and pancreatic (HPB) procedures in years to come. More than 40,000 new cases of liver cancer are diagnosed each year, causing more than 30,000 deaths in the U.S. alone. Gallbladder disease is also one of the most common conditions in the U.S., with more than 20 million people affected annually. In pediatrics, gall bladder removal, or cholecystectomy, is on the rise.

Procedures to treat these diseases have many challenges. During minimally invasive surgery, including laparoscopic cholecystectomy or robot-assisted hepatectomy, surgeons can struggle to precisely identify the bile ducts because of a narrow field of view or because they are embedded in fat or other tissues. Existing FDA-approved contrast agents that can enhance the biliary anatomy such as indocyanine green (ICG) aren’t well tailored for HPB surgeries because of the timing of their administration and their inferior ability to highlight biliary structures. In addition, while pre-operative imaging has improved outcomes, it cannot be used to predict leaks from the surgery itself.

What’s ahead

BL-760 was created at Children’s National and NCI by a team of experts in surgery and engineering, led by Anthony Sandler, M.D., senior vice president and surgeon-in-chief. They hope to continue their testing on the dye in the months ahead. The team was encouraged when Michele Saruwatari, M.D., a Joseph E. Robert Fellow in the Sheik Zayed Institute, recently won first place in the resident and fellow abstract presentation competition at the annual meeting of the Society of American Gastrointestinal and Endoscopic Surgeons.

“Having this tool in the operating room will change outcomes for our pediatric patients,” Sandler said.  “This dye has the potential to become an essential step in liver cancer surgery, cholecystectomy and treating other pediatric diseases like biliary atresia. I look forward to the day when we can get it in the hands of surgical teams.”

NCC-PDI Finalists

Pediatric medical device competition names finalists

Five finalists have been named in the prestigious annual “Make Your Medical Device Pitch for Kids!” competition presented by the National Capital Consortium for Pediatric Device Innovation (NCC-PDI). Representing innovations in pediatric technologies that aim to address unmet medical needs for children, these five finalists now have access to a pediatric accelerator program led by MedTech Innovator and will compete for a share of $150,000 in grant funding from the U.S. Food and Drug Administration (FDA) in the final virtual pitch event in October 2022. The pediatric pitch event is part of the 10th Annual Symposium on Pediatric Device Innovation, co-located with the MedTech Conference, powered by AdvaMed.

“Addressing unmet needs across pediatric populations is critical to advancing children’s health and we are delighted to once again work with pioneering companies that seek to bridge this care gap,” 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. “As an FDA-funded consortium, NCC-PDI serves as a critical device development resource, bringing together individuals and institutions that support viable pediatric innovations and create faster pathways to commercialization. We congratulate this year’s finalists and look forward to seeing the progress made in the coming months as they navigate the accelerator program.”

The following are the five pediatric device innovations that judges selected for the final competition:

  • CorInnova – Houston, TX – Minimally invasive biventricular non-blood contacting cardiac assist device to treat heart failure.
  • Innovation Lab – La Palma, CA – Mechanical elbow brace stabilizes tremors for pediatric ataxic cerebral palsy to improve the performance of Activities of Daily Living (ADLs).
  • Prapela – Biddeford, ME – Prapela’s incubator pad is the first innovation to improve the treatment of apnea of prematurity in over twenty years.
  • Tympanogen – Richmond, VA – Perf-Fix replaces surgical eardrum repair with a nonsurgical clinic procedure
  • Xpan – Concord, Ont. – Xpan’s universal trocar enables safest and most dynamic access and effortless upsizing in conventional/mini/robotic procedures.

Beginning in June 2022, the five finalists will participate in a pediatric-focused track of the MedTech Innovator accelerator, the world’s largest accelerator of medical devices.

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 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.

To date, NCC-PDI has mentored nearly 200 medical device sponsors to help advance their pediatric innovations, with 16 devices having received either their FDA market clearance or CE marking.

The accelerator program is the consortium’s latest addition to a network of resources and experts that it provides in support of pediatric innovators.

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.

Overcoming real and perceived barriers to pediatric device innovation

pediatric cardiac and vascular MRI coil

A working group of innovators, engineers and clinicians from Children’s National Hospital and other institutions came together to address the real and perceived barriers to the creation of pediatric devices, such as this pediatric cardiac and vascular MRI coil developed by Inkspace Imaging.

A working group of innovators, engineers and clinicians from Children’s National Hospital, Children’s Hospital of Orange County and other institutions came together to address the real and perceived barriers to pediatric device innovation through opportunities that may change the return-on-investment in this market and improve health outcomes.

The new report, published in the Journal of Translational Engineering in Health and Medicine, mentions barriers that impede the advancement of pediatric devices, including excessive limitations for testing and validation, lack of incentives, inadequate research models and inconsistent pediatric-related knowledge among companies, regulatory experts, ethic review panels and government reviewers.

To remove the real and perceived barriers fostering excessive limitations, the researchers suggest reducing the perceived risk by establishing guidelines that standardize the review process and ethical research models, incentivizing small companies to participate in pediatric device innovation.

To increase incentives, the researchers call for the development of pediatric versions of adult devices with or without enforcement of regulations, develop incentives for small, medium and large-size companies, extend patent protection and more.

Since science corroborates the device’s effectiveness and safety, tailored pediatric research models are needed to help advance pediatric device innovation. While randomized trials in well-defined cohorts are commonly used in the scientific quest, they do not reflect the clinical practice in the pediatric devices field.

“Overcoming this barrier will require greater opportunity for creativity in the design of clinical trials, including delayed entry, intent-to-treat analysis, personalized outcome measures, and post-hoc subgroup analysis,” said Terence et al. “Effective research for pediatric device innovation will require greater ability to rely on ‘real-world’ data from post-market use of the proposed device or similar devices.”

On the education side, stakeholders, such as device sponsors and researchers, must receive an improved education on pediatric devices, according to the authors. Pediatricians should also be added to the regulatory review panels and advisory boards, so decision-makers can receive the pediatric perspective and fold it into their considerations.

“The consensus outcome of this meeting is that there are multiple opportunities, and a flexible combination of new programs and regulatory changes can be created to benefit the multiple stakeholders in pediatric device development,” said Terence et al. “An essential component will be building a cadre of experts with the development, regulatory, and clinical expertise to support all innovators.”

Kolaleh Eskandanian, Ph.D., M.B.A., P.M.P., vice president and chief innovation officer at Children’s National Hospital adds that supporting and expanding pediatric innovation is a key focus of the new Children’s National Research & Innovation Campus, the 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, the campus provides a rich ecosystem of public and private partners which will help bolster pediatric innovation and commercialization.

Authors from Children’s Hospital Orange County include Terence Sanger, M.D., Nadine Afari, M.S., Anthony Chang, M.D., William Feaster, M.D., Sharief Taraman, M.D., Debra Beauregard, Brent Dethlefs, Tiffani Ghere, R.D., C.S.P., Mustafa Kabeer, M.D., and George Tolomiczenko.

Nikki Gillum Posnack

Research team develops new and improved method for studying cardiac function

Nikki Gillum Posnack

While researching how plastic affects heart function in sensitive populations, such as children born with congenital heart defects, Children’s National researcher Nikki Posnack, Ph.D., led a team that developed a new and improved, replicable method of performing simultaneous dual optical mapping to examine electrical activity and calcium for the study of cardiac function.

Since arriving at the Sheikh Zayed Institute for Pediatric Surgical Innovation, researcher Nikki Gillum Posnack, Ph.D., a principal investigator with the institute and assistant professor of pediatrics at the George Washington University School of Medicine and Health Sciences, has been focused on examining how exposure to plastic affects heart function in sensitive populations, such as children born with congenital heart defects. She performs optical mapping to conduct this research, but the industry standard approaches of either using dual cameras or sequential single cameras were cost prohibitive and technically challenging while also diminishing the quality of the imaging results.

Fast forward to July 2019 when Dr. Posnack and her team published “Plasticizer Interaction With the Heart” in the journal Arrhythmia and Electrophysiology, which used imaging techniques to reveal the impact of plastic chemicals on the electrical activity of the heart. Dr. Posnack’s laboratory has since expanded this technique and revealed a new replicable method of performing simultaneous dual optical mapping to examine electrical activity and calcium handling in the heart.

Sharing a new method for studying cardiac function

This groundbreaking method is itself the focus of a new BMC Biomedical Engineering journal article titled “Lights, camera, path splitter: a new approach for truly simultaneous dual optical mapping of the heart with a single camera.”

The article compares and contrasts the current standard for dual camera simultaneous configurations and single camera sequential configurations to Dr. Posnack’s new single camera simultaneous configuration.

Simultaneous dual mapping systems use two probes and dual dyes – one for electrical voltage and the other for calcium. While dual-dye combinations like Di-4-ANEPPS with Indo-1, Di-2-ANEPEQ and calcium green have been developed to separate fluorescence signals by emission, these dye combinations can have spectral overlap, creating the need for non-ideal emission bandpass to negate spectral overlap and/or the inclusion of a calcium probe with an inferior dissociation constant. Additionally, dual-sensor systems require proper alignment to ensure that fluorescence signals are being analyzed from the same tissue region on each individual detector, which could lead to erroneous results. The dual-camera optical setup is expensive, technically challenging and requires a large physical footprint that is often not feasible for basic science and teaching laboratories conducting critical research.

As an alternative, some researchers use a single camera configuration to sequentially image the voltage and calcium probes using excitation light patterning. This approach also has limitations. These single-sensor designs use dual-dye combinations that require two or more excitation light sources, but share a single emission band. Like the dual camera system, this platform design is also technically challenging since the different excitation light wavelengths require light source triggering, camera synchronization and frame interleaving. Due to timing coordination, decreased frame rates, excitation light ramp up/down times and shutter open/close times, single system setups require shorter exposure times compared to dual sensor setups, diminishing the signal-to-noise quality without offering the same temporal fidelity. There is a cost advantage to the single camera system, however, because the additional camera is often one of the most expensive components.

This new single camera, simultaneous dual optical mapping approach is the first multiparametric mapping system that simultaneously acquires calcium and voltage signals from cardiac preparations, using a commercially available optical path splitter, single camera and single excitation light. Using a large field of view sCMOS sensor that is faster and more sensitive, this configuration separates the two emission bands for voltage and calcium probes and simultaneously directs them to either sides of the single, large camera sensor. This protocol employs a commonly used dual-dye combination (RH237 and Rhod2-AM). In contrast, other protocols may require genetically-encoded indicators or fluorescent probes that are not yet commercially available.

The team validated the utility of the approach by performing high-speed simultaneous dual imaging with sufficient signal-to-noise ratio for calcium and voltage signals and specificity of emission signals with negligible cross-talk. Demonstrating the need for simultaneous electrical and calcium sensors, they found that when ventricular tachycardia is induced, there is spatially discordant calcium alternans present in different regions of the heart even when the electrical alternans remain concordant.

Having eliminated the second camera as well as the need for multiple excitation light sources, light pattering and frame interleaving, this system is more cost effective, simpler, and can be easily setup by various types of researchers, not just those with engineering backgrounds.

With a limited research budget and a background in physiology, Dr. Posnack worked collaboratively with her post-doctoral fellow Rafael Jaimes III, an engineer in the Sheikh Zayed Institute for Pediatric Surgical Innovation, to develop a cost-effective system that would enable her to truly study the effects of plastics on the heart.

Multidisciplinary approach

“We’re fortunate to have a multidisciplinary team in the Sheikh Zayed Institute so that I could work with an engineer to develop the technology and system we needed to propel our research,” said Dr. Posnack. “There are so many researchers who have the science background, but not necessarily the technical aptitude, and they get stymied in their research, so we’re proud that this paper will help other researchers replicate the system to study cardiac function.”

The research paper was funded by a grant from the National Institutes of Health as well as support from the Children’s Research Institute, Children’s National Heart Institute and the Sheikh Zayed Institute for Pediatric Surgical Innovation.

The applications for this optical mapping system are significant and Dr. Posnack has been consulted by other research teams looking to implement it in their labs. Additionally, Dr. Posnack has collaborated with several neuroscience teams at Children’s National Hospital, including one that is investigating the effects of hypoxia on brain and heart development, and another that is interested in using image modalities and data processing to analyze calcium as an indicator of neuron firing.

Dr. Posnack continues to use this new dual optical mapping system to further her research as she anticipates the publication of a new article about age-dependent changes in cardiac electrophysiology and calcium handling.

In an international study led by the National Human Genome Research Institute (NHGRI), researchers have successfully identified Williams-Beuren syndrome in diverse populations using clinical information and objective facial analysis technology developed by the Sheikh Zayed Institute for Pediatric Surgical Innovation at Children’s National.

The technology, which was featured by STAT as an ‘Editor’s Pick’ finalist in their recent competition to find the best innovation in science and medicine, enables users to compare the most relevant facial features characteristic of Williams-Beuren syndrome in diverse populations.

Williams-Beuren syndrome affects an estimated 1 in 7,500 to 10,000 people, with the most significant medical problems being cardiovascular, including high blood pressure. Though the syndrome is a genetic condition, most cases are not inherited. Signs and symptoms include intellectual disability and distinctive facial features including puffiness around the eyes, a short nose with a broad tip, full cheeks and a wide mouth with full lips.

Using the facial analysis technology, the researchers compared 286 African, Asian, Caucasian and Latin American children and adults with Williams-Beuren syndrome with 286 people of the same age, sex and ethnicity without the disease. They were able to correctly identify patients with the disease from each ethnic group with 95 percent or higher accuracy.

“Our algorithm found that the angle at the nose root is the most significant facial feature of the Williams-Beuren syndrome in all ethnic groups and also highlighted facial features that are relevant to diagnosing the syndrome in each group,” said Marius George Linguraru, D.Phil., developer of the facial analysis technology and an investigator in the study from Children’s National.

Linguraru and his team are working to create a simple tool that will enable doctors in clinics without state-of-the-art genetic facilities to take photos of their patients on a smartphone and receive instant results.

The technology was also highly accurate in identifying Noonan syndrome according to a study published in Sept. 2017, DiGeorge syndrome (22q11.2 deletion syndrome) in April 2017 and Down syndrome in Dec. 2016. The next study in the series will focus on Cornelia de Lange syndrome.

According to an international study led by the National Human Genome Research Institute (NHGRI), researchers have successfully used facial analysis software, developed by the Sheikh Zayed Institute for Pediatric Surgical Innovation at Children’s National, to identify Noonan syndrome in diverse populations.

Noonan syndrome is relatively common, affecting between 1 in 1,000 to 1 in 2,500 children, however few studies have been conducted in non-Europeans. For this study, the researchers evaluated children (average age of eight) with Noonan syndrome from 20 countries. Using the facial analysis software and clinical criteria, the researchers compared 161 white, African, Asian and Latin American children with Noonan syndrome with 161 people of the same age and gender without the disease. Using the software to analyze facial features, they were able to correctly diagnose patients with the disease from each ethnic group with 94 percent or higher accuracy.

“Our algorithm found widely spaced eyes as a significant facial feature in all ethnic groups and also highlighted facial features that are relevant to diagnosing the syndrome in each group,” said

Marius George Linguraru, D.Phil., developer of the facial analysis technology and an investigator in the study from Children’s National.

STAR robot is finalist in NASA iTech challenge

STAR Team

Children’s National Health System’s proprietary robotic surgical technology Smart Tissue Autonomous Robot (STAR) has been named one of the top ten finalists in the 2017 NASA iTech call for ideas challenge.

The Sheikh Zayed Institute for Pediatric Surgical Innovation’s intelligent Smart Tissue Autonomous Robot (STAR) has been named one of the top ten finalists in the 2017 NASA iTech challenge.

The team will present the project at the NASA iTech Forum on July 12-13, 2017 at the National Institute of Aerospace in Hampton, VA, where leaders from NASA and prospective stakeholders will evaluate the 10 finalists and select three top solutions.

“We’re honored to be selected as a finalist in this prestigious challenge,” said Peter C. Kim, M.D., vice president and associate surgeon in chief at Sheikh Zayed Institute at Children’s National. “Our technology is capable of many solutions that would be useful as part of NASAs deep space exploration, including intelligent pods capable of common intelligent autonomous surgical procedures.”

A cutting-edge system, STAR was the first to perform a successful autonomous robotic soft tissue surgery on a live subject in May 2016 and is licensed to Omniboros.

Facial analysis technology helps diagnose rare genetic disease

Facial Analysis Technology

A new study uses facial analysis technology developed at Children’s National to diagnose 22q1.2 deletion syndrome, also known as DiGeorge syndrome.

According to a new study led by the National Human Genome Research Institute (NHGRI), facial analysis technology can assist clinicians in making accurate diagnosis of 22q1.2 deletion syndrome, also known as DiGeorge syndrome. Using objective facial analysis software, developed by researchers from the Sheikh Zayed Institute for Pediatric Surgical Innovation at Children’s National, the study compared the most relevant facial features characteristic of DiGeorge syndrome in diverse populations. Based on a selection of 126 individual facial features, the researchers were able to correctly diagnose patients with the disease from different ethnic groups with 96.6 percent or higher accuracy.

“The results of the study demonstrated that the identification of rare diseases benefits from adapting to ethnic and geographic populations,” said Marius George Linguraru, D.Phil., developer of the facial analysis technology and an investigator in the study from Children’s National.

Linguraru and his team are also working on a simple tool that will enable doctors in clinics without state-of-the-art genetic facilities to take photos of their patients on a smartphone and receive instant results.
