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

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

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

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

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

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

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

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

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

Clinical Trial Spotlight: Is more really better? Dose escalation of multi-antigen targeted T cells to illicit a more robust response

T cell

As the promise of immunotherapy in treating patients with cancer becomes more evident, physician researchers at Children’s National are pushing the needle further along. Holly Meany, M.D., is leading a Phase 1 dose-escalation trial to determine the safety and efficacy of administering rapidly generated tumor multi-antigen associated specific cytotoxic T lymphocytes (TAA CTL) to patients who have undergone allogeneic hematopoietic stem cell transplantation (HSCT) or traditional therapy for a high-risk solid tumor due to the presence of refractory, relapsed and/or residual detectable disease.

“In the escalation portion of our trial, we found that the highest dose evaluated did not have unfavorable toxicity in these patients and is our recommended dose,” Dr. Meany said. “Our next step is an expansion of the trial in five distinct disease categories – Wilms tumor, neuroblastoma, rhabdomyosarcoma, adenocarcinoma and esophageal carcinoma – to examine efficacy on a broader level at the recommended dose.”

Dr. Meany and fellow research clinicians at Children’s National will evaluate not only what happens to the patients when given the additional dosage, but also what happens to the cells – How long will they last? Will they remain targeted against the same antigens or will they shift to target other proteins?

This novel trial is currently enrolling patients at Children’s National Health System in Washington, D.C.

Suvankar Majumdar

Spotlight on Suvankar Majumdar, M.D.

Suvankar Majumdar

As a provider with international experience, Suvankar Majumdar, M.D., joined Children’s National in August 2017 as chief of Children’s Division of Hematology within the Center for Cancer and Blood Disorders. Dr. Majumdar is excited to be at Children’s National because of the opportunities for growth, cutting-edge research and continuing education that our diverse population of patients can provide clinicians.

Born in Zambia, in southern Africa, and educated in the United Kingdom, Dr. Majumdar moved to Zimbabwe to study medicine, which he considers the turning point of his career. While in medical school, Dr. Majumdar oversaw and managed the treatment of patients with HIV and other chronic illnesses and determined that blood disorders, particularly sickle cell, was where he wanted to place his focus. Since then, he has served as the Director of the Comprehensive Pediatric Sickle Cell Program as well as Director of the Hemophilia Treatment Center at the University of Mississippi and is a recognized leader in hematology and sickle cell disease. It is this expertise, as well as his dedication to research studies, that have already made him an asset to Children’s National.

Within the Division of Hematology, Children’s providers focus on treating patients with blood disorders, bleeding and clotting disorders, red blood cell disorders (such as sickle cell) and more. Since coming to Children’s National, Dr. Majumdar has experienced a tremendous amount of dedication and enthusiasm from his colleagues. “I’m excited to build on what our faculty has accomplished so far. We’re already well poised to become a national leader in hematology,” he says. “I have no doubt that we will continue to accomplish our goals through collaboration and working toward a common life-saving cause.”

One of his immediate goals for the division is to focus on bringing improved patient care and accessibility in the surrounding Washington area. Additionally, Dr. Majumdar is currently conducting two research studies for sickle cell disease. As one of his studies enters the second phase, he’s focused on seeing the impact of an intravenous citrulline, a nitric oxide booster, on patients with sickle cell disease. Another study has begun to determine if specific genetic mutations that cause prolonged QT, or irregular heartbeats in patients, cause mortality, as sickle cell patients are predisposed to cardiac episodes.

It is Dr. Majumdar’s hope that the hematology team at Children’s National will also continue training the next generation of providers to advance research, education and clinical aspects of the field. To those looking to join the specialty, Dr. Majumdar suggests keeping an open mind when it comes to collaborating with colleagues. “My dad always said to my siblings and I that ‘to break one stick is easy, but to break three sticks is harder’ and really impressed upon us that we’re stronger together,” he says. “By working together, we’re more likely to produce the results that we’re looking for.”

Being located in the nation’s capital, providers at Children’s National are accustomed to seeing a diverse array of patients. For Dr. Majumdar, this presents a unique opportunity. “Meeting and interacting with different patients and families was really appealing when I decided to come to Children’s National. The variety of cases we see in the Division of Hematology can definitely present new challenges, but it’s also more rewarding,” he says.

Working with the pediatric population is also a passion of his. “Children are resilient and tend to bounce back quickly,” Dr. Majumdar says. “As a parent, I try to empathize with treatment concerns and always treat every child as if they were my own. I’m always going to make sure it’s the best level of care possible.”

Experimental fertility preservation provides hope for young men

germ cells in testicular tissues

Confirming the presence of germ cells in testicular tissues obtained from patients. Undifferentiated embryonic cell transcription factor 1 (UTF1) is an established marker of undifferentiated spermatogonia as well as the pan-germ cell marker DEAD-box helicase 4 (DDX4). UTF1 (green) and/or DDX4 (red) immunostaining was confirmed in 132 out of 137 patient tissues available for research, including patients who had received previous non-alkylating (B, E, H, K) or alkylating (C, F, I, L) chemotherapy treatment. © The Author(s) 2019. Published by Oxford University Press on behalf of the European Society of Human Reproduction and Embryology.

Testicular tissue samples obtained from 189 males who were facing procedures that could imperil fertility were cryopreserved at one university, proving the feasibility of centralized processing and freezing of testicular tissue obtained from academic medical centers, including Children’s National, scattered around the world.

“It’s not surprising that the University of Pittsburgh would record the highest number of samples over the eight-year period (51 patients), given its role as the central processing facility for our recruiting network of academic medical centers,” says Michael Hsieh, M.D., Ph.D., director of transitional urology at Children’s National. “Children’s National recruited the third-highest number of patients, which really speaks to the level of collaboration I have with Jeff Dome’s team and their commitment to thinking about the whole patient and longer-term issues like fertility.”

An estimated 2,000 U.S. boys and young men each year receive treatments or have cancers or blood disorders that place them at risk for infertility. While older youths who have undergone puberty can bank their sperm prior to undergoing sterilizing doses of chemotherapy or radiation, there have been scant fertility preservation options for younger boys. However, some older adolescents and young men are too sick or stressed to bank sperm. For patients with no sperm to bank or who are too sick or stressed to bank sperm, the experimental procedure of freezing testicular tissue in anticipation that future cell- or tissue-based therapies can generate sperm is the only option.

Recent research in experimental models indicates that such testicular tissue biopsies contain stem cells, blank slate cells, hinting at the potential of generating sperm from biopsied tissue.

“This study demonstrates that undifferentiated stem and progenitor spermatogonia may be recovered from the testicular tissues of patients who are in the early stages of their treatment and have not yet received an ablative dose of therapy. The function of these spermatogonia was not tested,” writes lead author Hanna Valli-Pulaski, Ph.D., research assistant professor at the University of Pittsburgh, and colleagues in a study published online May 21, 2019, in Human Reproduction.

Right now, hematologists and oncologists discuss future treatment options with patients and families, as well as possible long-term side effects, including infertility. At Children’s National, they also mention the ongoing fertility preservation study and encourage families to speak with Dr. Hsieh. He meets with families, explains the study goals – which include determining better ways to freeze and thaw tissue and separating malignant cells from normal cells – what’s known about experimental fertility preservation and what remains unknown. Roughly half of patients decide to enroll.

“This study is unique in that there is definitely a potential direct patient benefit,” Dr. Hsieh adds. “One of the reasons the study is compelling is that it presents a message of hope to the families. It’s a message of survivorship: We’re optimistic we can help your child get through this and think about long-term issues, like having their own families.”

In this phase of the study, testicular tissue was collected from centers in the U.S. and Israel from January 2011 to November 2018 and cryopreserved. Patients designated 25% of the tissue sample to be used for the research study; 75 percent remains stored in liquid nitrogen at temperatures close to absolute zero for the patient’s future use. The fertility preservation patients ranged from 5 months old to 34 years old, with an average age of 7.9 years.

Thirty-nine percent of patients had started medical treatment prior requesting fertility preservation. Sixteen percent received non-alkylating chemotherapy while 23% received alkylating chemotherapy, which directly damages the DNA of cancer cells.

The research team found that the number of undifferentiated spermatogonia per seminiferous tubule increase steadily with age until about age 11, then rise sharply.

“We recommend that all patients be counseled and referred for fertility preservation before beginning medical treatments known to cause infertility. Because the decision to participate may be delayed, it is encouraging that we were able to recover undifferentiated spermatogonia from the testes of patients already in the early stages of chemotherapy treatments,” Dr. Hsieh says.

In addition to Dr. Hsieh, study co-authors include lead author, H. Valli-Pulaski, K.A. Peters, K. Gassei, S.R. Steimer, M. Sukhwani, B.P. Hermann, L. Dwomor, S. David, A.P. Fayomi, S.K. Munyoki, T.

Engineering TGFB receptor to enhance NK cells and fight neuroblastoma

Catherine Bollard

“In this study, we have genetically engineered cord blood derived NK cells so that they are not only resistant to the devastating effects of TGFb, but they are not able to become activated in the presence of TGFb,” said, Catherine Bollard, M.B.Ch.B., M.D.

Catherine Bollard, M.B.Ch.B., M.D., and her research team published results showing potential efficacy of a novel cell therapeutic for treatment of pediatric patients with relapsed/refractory neuroblastoma.

The research paper, entitled, “Engineering the TGFβ receptor to Enhance the Therapeutic Potential of Natural Killer Cell as an Immunotherapy for Neuroblastoma,” was published on April 29, 2019 by Clinical Cancer Research and is being recognized for the potential efficacy of the “off the shelf” treatment for patients with relapsed/refractory neuroblastoma.

The researcher’s approach allows them to manipulate Natural Killer (NK) cells, expand and reinfuse them within a patient so they can fight cancer and disease.

“In this study, we have genetically engineered cord blood derived NK cells so that they are not only resistant to the devastating effects of TGFb, but they are not able to become activated in the presence of TGFb,” said, Dr. Bollard, who is the senior corresponding author of the study and director of the Center for Cancer and Immunology Research at the Children’s Research Institute. “In other words, turning the negative effects of TGFb into positive effects enhances the persistence and anti-tumor activity of these tumor-killing NK cells in vivo.”

NK cells are highly cytolytic, and their potent antitumor effects can be rapidly triggered by a lack of human leukocyte antigen (HLA) expression on interacting target cells, as in the case for a majority of solid tumors, including neuroblastoma. With neuroblastoma being a leading cause of pediatric cancer-related deaths, it presents as an ideal candidate for NK cell therapy.

“This manuscript encompasses a significant portion of work, in which we generated genetically-modified NK cells as an enhanced form of immunotherapy for neuroblastoma,” said Rachel Burga, Ph.D., lead author and graduate of the Institute for Biomedical Sciences at George Washington and Children’s National Health System.  “We’re very excited to share our pre-clinical findings which demonstrate the efficacy of approaches to “hijack” the TGFb receptor and target TGFb in the tumor microenvironment.”

She added that the approach will allow for the NK cells to simultaneously resist the immune suppression in the microenvironment and initiate activation to increase their ability to target tumor cells.

Pre-clinical testing and research for this trial began in 2016 and ended in 2019. “The idea came from a Department of Defense award given to Dr. Bollard and Dr. Cruz and they took the idea and reduced it to practice and showed feasibility for pre-clinical trial,” said Rohan Fernandes, Ph.D., assistant professor in the Department of Medicine at George Washington University and senior author on the manuscript.

Fernandes added that the timeframe to start the clinical trial is within the next two to four years at Children’s National.

Additional authors include Rachel A. Burga, Ph.D., Eric Yvon, Rohan Fernandes, Conrad Russell Cruz, and Catherine M. Bollard, M.B.Ch.B., M.D.

Research and Education Week honors innovative science

Billie Lou Short and Kurt Newman at Research and Education Week

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

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

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

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

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

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

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

Beth Tarini

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

Beth Tarini

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Clinical Trial Spotlight: Creating a super army to target CNS tumors

Eugene Hwang in an exam room

Following the noted success of CAR-T cells in treating leukemia, Eugene Hwang, M.D., and a team of physicians at Children’s National are studying the efficacy of using these white blood cell “armies” to fight central nervous system (CNS) tumors.

Following the noted success of CAR-T cells in treating leukemia, physicians at Children’s National are studying the efficacy of using these white blood cell “armies” to fight central nervous system (CNS) tumors. Employing a strategy of “supertraining” the cells to target and attack three tumor targets as opposed to just one, Eugene Hwang, M.D., and the team at Children’s are optimistic about using this immunotherapy technique on a patient population that hasn’t previously seen much promise for treatment or cure. The therapy is built on the backbone of T cell technology championed by Catherine Bollard, M.B.Ch.B., M.D., director of the Center for Cancer and Immunology Research, which is only available at Children’s National. Hwang sees this trial as an exciting start to using T cells to recognize resistant brain cancer. “We have never before been able to pick out markers on brain cancer and use the immune system to help us attack the cancer cells. This strategy promises to help us find treatments that are better at killing cancer and lessening side effects,” he says.

This Phase 1 dose-escalation is designed to determine the safety and feasibility of rapidly generated tumor multiantigen associated specific cytotoxic T lymphocytes (TAA-T) in patients with newly diagnosed diffuse intrinsic pontine gliomas (DIPGs) or recurrent, progressive or refractory non-brainstem CNS malignancies. Pediatric and adult patients who have high-risk CNS tumors with known positivity for one or more Tumor Associated Antigens (TAA) (WT1, PRAME and/or surviving) will be enrolled in one of two groups: Group A includes patients with newly diagnosed DIPGs who will undergo irradiation as part of their upfront therapy and Group B includes patients with recurrent, progressive or refractory CNS tumors including medulloblastoma, non-brainstem high-grade glioma, and ependymoma, among others. TAA-T will be generated from a patient’s peripheral blood mononuclear cells (PBMCs) or by apheresis. This protocol is designed as a phase 1 dose-escalation study. Group A patients: TAA-T will be infused any time >2 weeks after completion of radiotherapy. Group B patients: TAA-T will be infused any time >2 after completing the most recent course of conventional (non-investigational) therapy for their disease AND after appropriate washout periods as detailed in eligibility criteria.

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

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

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

Personalized guidelines:

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

Early detection:

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

Coordinated care:

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

Innovation:

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

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

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

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

Stat Madness 2019

Vote for Children’s National in STAT Madness

Stat Madness 2019

Children’s National Health System has been selected to compete in STAT Madness for the second consecutive year. Our entry for the bracket-style competition is “Sensitive liquid biopsy platform to detect tumor-released mutated DNA using patient blood and CSF,” a new technique that will allow kids to get better treatment for an aggressive type of pediatric brain tumor.

In 2018, Children’s first-ever STAT Madness entry advanced through five brackets in the national competition and, in the championship round, finished second. That innovation, which enables more timely diagnoses of rare diseases and common genetic disorders, helping to improve kids’ health outcomes around the world, also was among four “Editor’s Pick” finalists, entries that spanned a diverse range of scientific disciplines.

“Children’s National researchers collaboratively work across divisions and departments to ensure that innovations discovered in our laboratories reach clinicians in order to improve patient care,” says Mark Batshaw, M.D., Children’s Executive Vice President, Chief Academic Officer and Physician-in-Chief. “It’s gratifying that Children’s multidisciplinary approach to improving the lives of children with brain tumors has been included in this year’s STAT Madness competition.”

Pediatric brain cancers are the leading cause of cancer-related death in children younger than 14. Children with tumors in their midline brain structures have the worst outcomes, and kids diagnosed with diffuse midline gliomas, including diffuse intrinsic pontine glioma, have a median survival of just 12 months.

“We heard from our clinician colleagues that many kids were coming in and their magnetic resonance imaging (MRI) suggested a particular type of tumor. But it was always problematic to identify the tumor’s molecular subtype,” says Javad Nazarian, Ph.D., MSC, a principal investigator in Children’s Center for Genetic Medicine Research. “Our colleagues wanted a more accurate measure than MRI to find the molecular subtype. That raised the question of whether we could actually look at their blood to determine the tumor subtype.”

Children’s liquid biopsy, which remains at the research phase, starts with a simple blood draw using the same type of needle as is used when people donate blood. When patients with brain tumors provide blood for other laboratory testing, a portion of it is used for the DNA detective work. Just as a criminal leaves behind fingerprints, tumors shed telltale clues in the blood. The Children’s team searches for the histone 3.3K27M (H3K27M), a mutation associated with worse clinical outcomes.

“With liquid biopsy, we were able to detect a few copies of tumor DNA that were hiding behind a million copies of healthy DNA,” Nazarian says. “The blood draw and liquid biopsy complement the MRI. The MRI gives the brain tumor’s ZIP code. Liquid biopsy gives you the demographics within that ZIP code.”

Working with collaborators around the nation, Children’s National continues to refine the technology to improve its accuracy. The multi-institutional team published findings online Oct. 15, 2018, in Clinical Cancer Research.

Even though this research technique is in its infancy, the rapid, cheap and sensitive technology already is being used by people around the globe.

“People around the world are sending blood to us, looking for this particular mutation, H3K27M, ” says Lindsay B. Kilburn, M.D., a Children’s neurooncologist, principal investigator at Children’s National for the Pacific Pediatric Neuro-Oncology Consortium, and study co-author. “In many countries or centers, children do not have access to teams experienced in taking a biopsy of tumors in the brainstem, they can perform a simple blood draw and have that blood processed and analyzed by us. In only a few days, we can provide important molecular information on the tumor subtype previously only available to patients that had undergone a tumor biopsy.”

“With that DNA finding, physicians can make more educated therapeutic decisions, including prescribing medications that could not have been given previously,” Nazarian adds.

The STAT Madness round of 64 brackets opened March 4, 2019, and the championship round voting concludes April 5 at 5 p.m. (EST).

In addition to Nazarian and Dr. Kilburn, study co-authors include Eshini Panditharatna, Madhuri Kambhampati, Heather Gordish-Dressman, Ph.D., Suresh N. Magge, M.D., John S. Myseros, M.D., Eugene I. Hwang, M.D. and Roger J. Packer, M.D., all of Children’s National; Mariam S. Aboian, Nalin Gupta, Soonmee Cha, Michael Prados and Co-Senior Author Sabine Mueller, all of University of California, San Francisco; Cassie Kline, UCSF Benioff Children’s Hospital; John R. Crawford, UC San Diego; Katherine E. Warren, National Cancer Institute; Winnie S. Liang and Michael E. Berens, Translational Genomics Research Institute; and Adam C. Resnick, Children’s Hospital of Philadelphia.

Manufacturing technologies lag behind breakthroughs in CAR-T cancer treatment

tubes filled with pink liquid

Drug companies around the country are banking on the cutting-edge cancer treatments known as CAR-T, but many manufacturing processes are holding back the treatment from reaching the market. With the success of CAR-T, which essentially re-trains T Cells to identify and target the cancer-causing cells, many manufacturers still need to catch up in the development process.

Currently, there are nearly 700 CAR-T studies in the database ClinicalTrials.gov, including 152 industry-sponsored trials that are active, recruiting or enrolling by invitation. According to market research firm, Coherent Market Insights, they predict the CAR-T market will grow to $8 billion worldwide by 2028 from $168 million in 2018.

Catherine Bollard, M.B.Ch.B., M.D., director of the Center for Cancer and Immunology Research at Children’s National Health System, was featured in a recent Bloomberg Law article stating that academics, industry participants and medical product regulators are trying to catch up with the technology and determine the best standards for developing these products. Although this is an exciting and positive time in the field of oncology, it also presents a big learning curve.

Making these cells requires extracting patients T cells. They are then genetically engineered in a laboratory to produce proteins that allow them to identify cancer-causing cells. The new cells are then multiplied and then reintroduced into the body to kill off the cancer cells. The entire process can take a few weeks to complete.

“This is not a drug,” Bollard said. “This is a living biologic, and it comes from the patient and individuals. There’s so much variability.”

Along with manufacturing challenges, the outlook on creating more therapies is looking good. The FDA predicts that it will be approving 10 to 20 gene therapy products a year by 2025. Other companies are working to develop a manufacturing platform that can help reduce the complexity of the current system and ultimately make CAR-T manufacturing easier to scale.

Clinical Trial Spotlight: Treating tumors with ThermoDox® and MR-HIFU

Karun Sharma, M.D., is working with AeRang Kim, M.D., Ph.D., to evaluate the use of ThermoDox®, a heat-activated chemotherapy drug, in combination with noninvasive magnetic resonance-guided high-intensity focused ultrasound (MR-HIFU) to treat refractory or relapsed solid tumors in children and young adults.

A Phase I Study of Lyso-thermosensitive Liposomal Doxorubicin (LTLD, ThermoDox®) and Magnetic Resonance-Guided High Intensity Focused Ultrasound for Relapsed or Refractory Solid Tumors in Children, Adolescents, and Young Adults.

This study is looking to determine the maximum tolerated dose (MTD) and recommended phase 2 dose (RP2D) of lyso-thermosensitive liposomal doxorubicin (LTLD), a heat-activated formulation of liposomal doxorubicin with unique property of heat-activated release of doxorubicin, administered in combination with magnetic resonance-guided high-intensity focused ultrasound (MR-HIFU) in children with relapsed/refractory solid tumors.

MR-HIFU is an innovative device that provides precise and controlled delivery of heat inside a tumor using an external applicator. Unlike other heating systems used in local therapy, MR-HIFU is entirely non-invasive and does not use any radiation. Integration of MR imaging allows for real-time temperature monitoring for accurate and precise targeting of tumors. LTLD is a novel formulation of doxorubicin with the unique property of heat-activated release. This selective drug delivery mechanism allows for local and rapid release of doxorubicin in high concentrations in tumors when heated. This novel combination may potentiate known effective therapy to improve local control and drug delivery without increasing toxicity.

Children’s National Health System and Celsion Corp, a leading oncology drug-development company, were the first to launch a clinical study in the U.S. that evaluates the use of ThermoDox® with MR-HIFU. Learn more about the clinical trial.

AlgometRX

Breakthrough device objectively measures pain type, intensity and drug effects

AlgometRX

Pediatric anesthesiologist Julia C. Finkel, M.D., of Children’s National Health System, gazed into the eyes of a newborn patient determined to find a better way to measure the effectiveness of pain treatment on one so tiny and unable to verbalize. Then she realized the answer was staring back at her.

Armed with the knowledge that pain and analgesic drugs produce an involuntary response from the pupil, Dr. Finkel developed AlgometRx, a first-of-its-kind handheld device that measures a patient’s pupillary response and, using proprietary algorithms, provides a diagnostic measurement of pain intensity, pain type and, after treatment is administered, monitors efficacy. Her initial goal was to improve the care of premature infants. She now has a device that can be used with children of any age and adults.

“Pain is very complex and it is currently the only vital sign that is not objectively measured,” says Dr. Finkel, who has more than 25 years of experience as a pain specialist. “The systematic problem we are facing today is that healthcare providers prescribe pain medicine based on subjective self-reporting, which can often be inaccurate, rather than based on an objective measure of pain type and intensity.” To illustrate her point, Dr. Finkel continues, “A clinician would never prescribe blood pressure medicine without first taking a patient’s blood pressure.”

The current standard of care for measuring pain is the 0-to-10 pain scale, which is based on subjective, observational and self-reporting techniques. Patients indicate their level of pain, with zero being no pain and ten being highest or most severe pain. This subjective system increases the likelihood of inaccuracy, with the problem being most acute with pediatric and non-verbal patients. Moreover, Dr. Finkel points out that subjective pain scores cannot be standardized, heightening the potential for misdiagnosis, over-treatment or under-treatment.

Dr. Finkel, who serves as director of Research and Development for Pain Medicine at the Sheikh Zayed Institute for Pediatric Surgical Innovation at Children’s National, says that a key step in addressing the opioid crisis is providing physicians with objective, real-time data on a patient’s pain level and type, to safely prescribe the right drug and dosage or an alternate treatment.,

She notes that opioids are prescribed for patients who report high pain scores and are sometimes prescribed in cases where they are not appropriate. Dr. Finkel points to the example of sciatica, a neuropathic pain sensation felt in the lower back, legs and buttocks. Sciatica pain is carried by touch fibers that do not have opioid receptors, which makes opioids an inappropriate choice for treating that type of pain.

A pain biomarker could rapidly advance both clinical practice and pain research, Dr. Finkel adds. For clinicians, the power to identify the type and magnitude of a patient’s nociception (detection of pain stimuli) would provide a much-needed scientific foundation for approaching pain treatment. Nociception could be monitored through the course of treatment so that dosing is targeted and personalized to ensure patients receive adequate pain relief while reducing side effects.

“A validated measure to show whether or not an opioid is indicated for a given patient could ease the health care system’s transition from overreliance on opioids to a more comprehensive and less harmful approach to pain management,” says Dr. Finkel.

She also notes that objective pain measurement can provide much needed help in validating complementary approaches to pain management, such as acupuncture, physical therapy, virtual reality and other non-pharmacological interventions.

Dr. Finkel’s technology, called AlgometRx, has been selected by the U.S. Food and Drug Administration (FDA) to participate in its “Innovation Challenge: Devices to Prevent and Treat Opioid Use Disorder.” She is also the recipient of Small Business Innovation Research (SBIR) grant from the National Institute on Drug Abuse.

Unexpected heterogeneity in CNS-PNET patients treated as a single entity

Eugene Hwang

“We found that some patients diagnosed with standard tools underwent much more treatment than necessary or intended,” said Eugene Hwang, M.D.

Eugene I. Hwang, M.D., a neuro-oncologist in the Center for Cancer and Blood Disorders, and other researchers at Children’s National Health System, Seattle Children’s Hospital and Research Institute, the Fred Hutchinson Cancer Research Center and the Hopp-Children’s Cancer Center at the NCT Heidelberg recently published the results of a clinical trial focusing on children with histologically diagnosed supratentorial primitive neuroectodermal tumors (CNS-PNET) and pineblastomas (PBLs).

The clinical trial, published online October 17, 2018 in the Journal of Clinical Oncology, included children and adolescents aged 3-22 with these brain cancers who were randomly assigned to receive carboplatin during radiation and/or isotretinoin after the standard intensive therapy (high-dose craniospinal radiation and months of inpatient chemotherapy).  Importantly, because each patient was treated prospectively according to the clinical trial design, the conclusions related to tumor biology were felt to be less affected by varied treatment plans.

“This trial really highlighted the importance of new molecular testing methods in accurately diagnosing some of the brain cancers included in the trial. We found that some patients diagnosed with standard tools underwent much more treatment than necessary or intended.” says Dr. Hwang. “Kids who aren’t receiving the right form of cancer treatment may not get better despite months and months of intensive treatment.”

During this clinical trial, 85 participants with institutionally-diagnosed CNS-PNETs/PBLs were enrolled. Out of the 60 patients with sufficient tissue, 31 were non-pineal in location, 22 of which represented tumors that did not fit in the diagnoses intended for trial inclusion.

The researchers discovered that patient outcomes across each molecularly-diagnosed tumor type were strikingly different. Patients with molecularly-confirmed supratentorial embryonal tumors/PBLs exhibited a five-year event free survival (EFS) and an overall survival rate of 62 percent and 78.5 percent, respectively. However, patients with molecularly-classified high-grade gliomas (HGGs) had a five-year EFS of 5.6 percent and OS of 12 percent, showing no benefit even with the chemotherapy and craniospinal radiation.

Researchers determined that for patients with CNS-PNETs/PBLs, prognosis is considerably better than previously assumed when molecularly-confirmed HGG are removed. Dr. Hwang and co-authors concluded that molecular diagnosis can greatly aid standard pathological diagnostic tools, preventing unnecessary intensive therapy for some patients while enabling more rational treatment for others.

“The findings from our clinical trial have highlighted the immense challenges of histology-based diagnosis for some types of pediatric brain tumors, and the enormous importance this has for children with brain cancer,” Dr. Hwang says. “We hope that ultimately our study will pave the way for molecular profiling to become a standard component of initial diagnosis.”

The impact of surveillance imaging to detect relapse in Wilms tumor patients

Jeffrey Dome

Dr. Jeffrey Dome, M.D., Ph.D., vice president, Center for Cancer and Blood Disorders.

The Children’s Oncology Group published an article in the Journal of Clinical Oncology looking at the impact that surveillance imaging has on patients with Wilms tumor (WT), the most common kidney cancer in children.

Despite the risks and costs, the use of computed tomography (CT) for routine surveillance to detect recurrence in patients with WT has increased in recent years. The rationale for using CT scans rather than chest x-rays (CXR) and abdominal ultrasounds (US) is that CT scans are more sensitive, thereby enabling recurrences to be detected earlier.

In this study, led by Jeffrey S. Dome, M.D., Ph.D, vice president of the Center for Cancer and Blood Disorders at Children’s National Health System, researchers conducted a retrospective analysis of patients enrolled in the fifth National Wilms Tumor Study (NWTS-5) who experienced relapse to determine if relapse detection with CT scan correlates with improved overall survival compared with relapse detection by CXR or abdominal US.

A total of 281 patients with favorable-histology WT (FHWT) were included in the analysis. The key findings of the study were that:

  • Among patients with relapse after completion of therapy, outcome was improved in patients whose relapse was detected by surveillance imaging rather after signs and symptoms developed.
  • A higher disease burden at relapse, defined by the diameter of the relapsed tumor and the number of sites of relapse, was associated with inferior survival.
  • Relapses detected by CT scan were detected earlier and were smaller on average than relapses detected by CXR or US.
  • However, there was no difference in survival between patients whose relapse was detected by CT versus CXR or US.

An analysis of radiation exposure levels showed that surveillance regimes including CT scans have about seven times the radiation exposure compared to regimens including only CXR and US. Moreover, the cost to detect each recurrence reduced by 50 percent when CXR and US are used for surveillance.

“The results of this study will be practice changing,” said Dr. Dome, one of the doctors leading the clinical trial. “The extra sensitivity that CT scans provide compared to CXR and US do not translate to improved survival and are associated with the downsides of extra radiation exposure, cost and false-positive results that can lead to unnecessary stress and medical interventions,” he added. “Although counter-intuitive, the more sensitive technology is not necessarily better for patients.”

In conclusion, the doctors found that the elimination of CT scans from surveillance programs for unilateral favorable histology Wilms tumor is unlikely to compromise survival. However, it could result in substantially less radiation exposure and lower health care costs. Overall, the risk-benefit ratio associated with imaging modalities should be considered and formally studied for all pediatric cancers.

Children’s National launches Open DIPG Initiative

Javad Nazarian

Javad Nazarian, Ph.D., MSC, has played an important role in establishing the Open DIPG Initiative. He hopes that the Open DIPG Initiative will serve as a model for centralized disease-specific efforts that will bring research findings one step closer to clinical translation.

A collaborative team of doctors and researchers at Children’s National Health System today announced the launch of the Open DIPG Initiative through the Children’s Brain Tumor Tissue Consortium (CBTTC).

The primary goals for the project will be to generate DIPG Omics which will help decipher major molecular characteristics of diffuse intrinsic pontine glioma (DIPG). Specifically, these will include genomics, proteomics, transcriptomics and epigenomics for primary analyses, centralize all DIPG Omics for secondary analyses, integrate the new DIPG data and unify DIPG expertise (data scientists, researchers, new talent, etc.) to analyze the DIPG genomic data.

CBTTC Scientific Co-Chairs Javad Nazarian, Ph.D., MSC, principal investigator, and Adam Resnick, Ph.D., have played important roles in establishing the Open DIPG Initiative. They hope that the Open DIPG Initiative will serve as a model for centralized disease-specific efforts that will bring research findings one step closer to clinical translation.

Pediatric brain tumors are the leading cause of disease-related death in children. Unlike many adult cancers, the causes of pediatric brain tumors remain largely unknown, and common therapies have remained mostly unchanged over the last four decades. To address these challenges, clinicians and researchers have embraced the emergence of sequencing technologies and deep molecular characterization of tumors to define novel, targeted approaches and individualized therapies.

However, harnessing such data-driven approaches has been a challenge due to limited accessibility to datasets and shared discovery platforms that can empower large-scale integration of datasets for worldwide access and cross-disease analyses.

As a part of this initiative, the Open DIPG Initiative has collected, generated and annotated the largest cohort of DIPG genome data to date. Specifically, these datasets contain more than 1,000 genomes associated with pediatric high-grade gliomas, with over 500 DIPG cases. The Open DIPG has been a part of a larger effort known as the Pediatric Brain Tumor Atlas, which aims to uncover the molecular basis of childhood cancers.

Committed to accelerated discovery, the CBTTC is partnering with the Kids First Data Resource Center (DRC) and the newly developed Kids First Data Resource Portal, which was also launched today.

“The combination of consortia-based initiatives, partnerships with foundations and new discovery platforms being announced today, with the support of the National Institutes of Health (NIH), provides for entirely new and transformative ways of doing science on behalf of children with brain tumors,” said Adam Resnick, Ph.D., principal investigator of the Kids First DRC.

The Open DIPG initiative will be launched as a part of the Pediatric Brain Tumor Atlas and has been funded by families as well as the NIH Gabriella Miller Kids First Act fund. The fund was launched in 2015 and named after Gabriella Miller, a former patient at Children’s National who lost her life to DIPG.

Effectively expressing empathy to improve ICU care

Tessie October

“Families who feel we’re really listening and care about what they have to say are more likely to feel comfortable as they put their child’s life in our hands a second, third or fourth time,” says Tessie W. October, M.D., M.P.H.

In nearly every intensive care unit (ICU) at every pediatric hospital across the country, physicians hold numerous care conferences with patients’ family members daily. Due to the challenging nature of many these conversations – covering anything from unexpected changes to care plans for critically ill children to whether it’s time to consider withdrawing life support – these talks tend to be highly emotional.

That’s why physician empathy is especially important, says Tessie W. October, M.D., M.P.H., critical care specialist at Children’s National Health System.

Several studies have shown that when families believe that physicians hear, understand or share patients’ or their family’s emotions, patients can achieve better outcomes, Dr. October explains. When families feel like their physicians are truly empathetic, she adds, they’re more likely to share information that’s crucial to providing the best care.

“For the most part, our families do not make one-time visits. They return multiple times because their children are chronically ill,” Dr. October says. “Families who feel we’re really listening and care about what they have to say are more likely to feel comfortable as they put their child’s life in our hands a second, third or fourth time. They’re also less likely to regret decisions made in the hospital, which makes them less likely to experience long-term psychosocial outcomes like depression and anxiety.”

What’s the best way for physicians to show empathy? Dr. October and a multi-institutional research team set out to answer this question in a study published online in JAMA Network Open on July 6, 2018.

With families’ consent, the researchers recorded 68 care conferences that took place at Children’s pediatric ICU (PICU) between Jan. 3, 2013, to Jan. 5, 2017. These conversations were led by 30 physicians specializing in critical care, hematology/oncology and other areas and included 179 family members, including parents.

During these conferences, the most common decision discussed was tracheostomy placement – a surgical procedure that makes an opening in the neck to support breathing – followed by the family’s goals, other surgical procedures or medical treatment. Twenty-two percent of patients whose care was discussed during these conferences died during their hospitalization, highlighting the gravity of many of these talks.

Dr. October and colleagues analyzed each conversation, counting how often the physicians noticed opportunities for empathy and how they made empathetic statements. The researchers were particularly interested in whether empathetic statements were “buried,” which means they were:

  • Followed immediately by medical jargon
  • Followed by a statement beginning with the word “but” that included more factual information or
  • Followed by a second physician interrupting with more medical data.

That compares with “unburied” empathy, which was followed only by a pause that provided the family an opportunity to respond. The research team examined what happened after each type of empathetic comment.

The researchers found that physicians recognized families’ emotional cues 74 percent of the time and made 364 empathetic statements. About 39 percent of these statements were buried. In most of these instances, says Dr. October, the study’s lead author, the buried empathy either stopped the conversation or led to family members responding with a lack of emotion themselves.

After the nearly 62 percent of empathetic statements that were unburied, families tended to answer in ways that revealed their hopes and dreams for the patient, expressed gratitude, agreed with care advice or expressed mourning—information that deepened the conversation and often offered critical information for making shared decisions about a patient’s care.

Physicians missed about 26 percent of opportunities for empathy. This and striving to make more unburied empathetic statements are areas ripe for improvement, Dr. October says.

That’s why she and colleagues are leading efforts to help physicians learn to communicate better at Children’s National. To express empathy more effectively, Dr. October recommends:

  • Slow down and be in the moment. Pay close attention to what patients are saying so you don’t miss their emotional cues and opportunities for empathy.
  • Remember the “NURSE” mnemonic. Empathetic statements should Name the emotion, show Understanding, show Respect, give Support or Explore emotions.
  • Avoid using the word “but” as a transition. When you follow an empathetic statement with “but,” Dr. October says, it cancels out what you said earlier.
  • Don’t be afraid to invite strong emotions. Although it seems counterintuitive, Dr. October says helping patients express strong feelings can help process emotions that are important for decision-making.

In addition to Dr. October, study co-authors include Zoelle B. Dizon, BA, Children’s National; Robert M. Arnold, M.D., University of Pittsburgh Medical Center; and Senior Author, Abby R. Rosenberg, M.D., MS, University of Washington School of Medicine.

Bladder cancer’s unique bacterial “fingerprint”

Michael H. Hsieh, M.D., Ph.D.

Michael H. Hsieh, M.D., Ph.D.

Decades ago, researchers thought that the native bacteria scattered throughout the human body—such as in the gut, the oral cavity and the skin—served little useful purpose. This microbiota, whose numbers at least match those of the cells in the body they live on and in, were considered mostly harmless hitchhikers.

More recently, research has revealed that these natural flora play key roles in maintaining and promoting health. In addition, studies have shown that understanding what a “typical” microbiome looks like and how it might change over time can provide an early warning system for some health conditions, including cancer.

Now, a small, multi-institutional study conducted in experimental models suggests that as bladder cancer progresses, it appears to be associated with a unique bacterial fingerprint within the bladder—a place thought to be bacteria-free except in the case of infection until just a few years ago. The finding opens the possibility of a new way to spot the disease earlier.

Bladder cancer is the fourth-most common malignancy among U.S. men but, despite its prevalence, mortality rates have remained stubbornly high. Patients often are diagnosed late, after bladder cancer has advanced. And, it remains difficult to discern which patients with non-invasive bladder cancer will go on to develop muscle-invasive disease.

Already, researchers know that patients with grade 4 oral squamous cell carcinoma, women with increasingly severe grades of cervical cancer and patients with cirrhosis who develop liver cancer have altered oral, vaginal and gut microbiomes, respectively.

New technological advances have led to identification of a diverse community of bacteria within the bladder, the urinary microbiome. Leveraging these tools, a research team that includes Children’s National Health System investigators studied whether an experimental model’s urinary bacterial community changed as bladder cancer progressed, evolving from a microbiome into a urinary “oncobiome.”

To test the hypothesis, the research team led by Michael H. Hsieh, M.D., Ph.D., a Children’s urologist, exposed an experimental model of bladder cancer to a bladder-specific cancer-causing agent, n-butyl-n-(4-hydroxybutyl) nitrosamine (BBN). Bladder cancers induced by BBN closely resemble human cancers in tissue structure at the microscopic level and by gene expression analyses. Ten of the preclinical models received a .05 percent concentration of BBN in their drinking water over five months and were housed together. Ten other experimental models received regular tap water and shared a separate, adjacent cage.

Researchers collected urine samples ranging from 10 to 100 microliters at the beginning of the longitudinal study, one week after it began, then once monthly. They isolated microbial DNA from the urine and quantified it to determine how much DNA was microbial. All of the bladders from experimental models exposed to BBN and two bladders from the control group were analyzed by a pathologist trained in bladder biology.

According to the study published online July 5, 2018, by the biology preprint server Biorxiv, they found a range of pathologies:

  • Five of the experimental models that received BBN did not develop cancer but had histology consistent with inflammation. Three had precancer on histology: urothelial dysplasia, hyperplasia or carcinoma in situ. Two developed cancer: invasive urothelial carcinomas, one of which had features of a squamous cell carcinoma.
  • The experimental model that developed invasive carcinoma had markedly different urinary bacteria at baseline, with Rubellimicrobium, a gram negative organism found in soil that has not been associated with disease previously, Escherichia and Kaistobacter, also found in soil, as the most prominent bacteria. By contrast, in the other experimental models the most common urinary bacteria were Escherichia, Prevotella, Veillonella, Streptococcus, Staphyloccoccus and Neisseria.
  • By month four, the majority of experimental models exposed to BBN had significantly higher proportion of Gardnerella and Bifidobacterium compared with their control group counterparts.

“Closely analyzing the urinary bacterial community among experimental models exposed to BBN, we saw distinct differences in microbial profiles by month four that were not present in earlier months,” Dr. Hsieh says. “While Gardnerella is associated with the development of cancer, Bifidobacterium has been shown to exert antitumor immunity, and its increasing abundance points to the need for additional research to understand its precise role in oncogenesis.”

Dr. Hsieh adds that although the study is small, its findings are of significance to children who are prone to developing urinary tract infections (UTIs), including children with spina bifida, due to the association between UTIs and bladder cancer. “This work is important because it not only suggests that the urinary microbiome could be used to diagnose bladder cancer, but that it could also perhaps predict cancer outcomes. If the urinary microbiome contributes to bladder carcinogenesis, it may be possible to favorably change the microbiome through antibiotics and/or probiotics in order to treat bladder cancer.”

In addition to Dr. Hsieh, co-authors include Catherine S. Forster, M.D., M.S., and Crystal Stroud, of Children’s National; James J. Cody, Nirad Banskota, Yi-Ju Hsieh and Olivia Lamanna, of the Biomedical Research Institute; Dannah Farah and Ljubica Caldovic, of The George Washington University; and Olfat Hammam, of Theodor Bilharz Research Institute.

The brain tumor field moves forward with new findings and a research grant

Yuan Zhu

Yuan Zhu, Ph.D., and other experts completed new research findings evaluating the effects of manipulating the growth-promoting signaling pathways in brain tumors associated with adults and children.

This month, experts at Children’s National Health System made great strides in brain tumor research, specifically in gliomas, glioblastomas and medulloblastomas. Led by Yuan Zhu, Ph.D., the scientific director and Gilbert Endowed Professor of the Gilbert Family Neurofibromatosis Institute and Center for Cancer and Immunology Research at Children’s National, the team completed new research findings evaluating the effects of manipulating the growth-promoting signaling pathways in brain tumors associated with adults and children. Dr. Zhu’s research was recently published in Cell Reports and he was also awarded a U.S. Department of Defense (DoD) grant to gain a better understanding of how low-grade gliomas form. Together, this work moves the needle on developing more effective treatments for these debilitating and life-threatening tumors.

The study

In his recently published paper, Dr. Zhu and his colleagues, including Drs. Seckin Akgul and Yinghua Li, studied glioblastomas, the most common brain tumor in adults, and medulloblastomas, the most common brain tumor found in children, in genetically engineered experimental models. Dr. Zhu found that when they removed the p53 gene (the most commonly mutated tumor suppressor gene in human cancers) in the experimental model’s brain, most developed malignant gliomas and glioblastomas, while Sonic Hedgehog (SHH)-subtype (SHH) medulloblastomas were also observed. They further suppressed the Rictor/mTorc2 molecular pathway that is known in the regulation of tumor growth. This action greatly reduced the incidence of malignant gliomas and extended the survival of the models, validating the concept that Rictor/mTorc2 could be a viable drug target for this lethal brain cancer in adults.

The study also found that the same Rictor/mTorc2 molecular pathway serves the opposite function in SHH medulloblastoma formation, acting as a tumor suppressor. Findings suggest that if the same drug treatment is used for treating SHH medulloblastoma in children, it could potentially have an adverse effect and promote growth of the tumors.

Ultimately, the study demonstrates that Rictor/mTORC2 has opposing functions in glioblastomas in adults and SHH medulloblastomas in children. While drug therapies targeting Rictor/mTORC2 may be successful in adults, the findings reveal the risks of treating children with pediatric brain tumors when using the same therapies.

The grant

Continuing the study of brain tumors, Dr. Zhu recently received a $575,000 grant from DoD to research benign gliomas, with the hope of gaining a greater understanding of how the tumors form. Low-grade gliomas, or benign brain tumors, are the most common brain tumors in children. While not lethal like their high-grade counterpart, these tumors can lead to significant neurological defects, permanently impacting a child’s quality of life. Most commonly, the tumor can impair vision, often leading to blindness.

Since the tumors only occur in children under the age of eight, Dr. Zhu believes they are linked to neural stem or progenitor cells that exist in the optic nerve only during development, or when children are under eight-years-old. To test if his hypothesis is correct, Dr. Zhu will develop a preclinical model that mimics human brain tumors to study the development of the optic nerve. If his theory proves correct, Dr. Zhu’s long-term goal is to develop a strategy that prevents the tumor formation from ever occurring, ultimately preventing vision loss in children. The grant begins in July and will run for three years.

Improving the understanding of medulloblastoma

Brian Rood

Brian Rood, M.D., employed quantitative proteomics to tumor samples that led to novel therapeutic targets for Medulloblastoma and other tumors.

In a recently published study, Brian Rood, M.D., a neuro-oncologist at Children’s National Health System, employed quantitative proteomics to tumor samples, a technique that could lead to novel therapeutic targets for medulloblastoma and other tumors in the future.

Currently, many experts use genomic characterization to understand the genetic makeup of cancer cells, which has deepened the field’s collective knowledge of tumor biology. However, it has remained challenging to infer specific information about how the tumors will respond and consequently develop more effective therapies. Medulloblastoma is the most common pediatric, malignant brain tumor. Through Dr. Rood’s research using proteomic analysis, he was able to identify and measure the protein makeup of medulloblastoma, which led to a potential pathway for clinical intervention to treat this life-threatening cancer. The findings were published online June 7, 2018, in Acta Neuropathologica Communications.

“The goal of this research was to find out how these tumor cells function at the protein level, which may ultimately help the field identify drug therapies to stop them,” says Dr. Rood. “The genes of a cancer cell are like a blueprint for a building, but the blueprints aren’t always followed in a cancer cell: Not every active gene will produce its corresponding protein. Proteins do the work of the cell, and understanding them will provide a better overall understanding of a cancer cell’s biology.”

Dr. Rood compared proteomic and genomic data to confirm that genetics do not accurately predict the quantity of proteins. By directly quantitating the proteins and comparing them between different subgroups of the disease, they were able to identify protein-based pathways driving tumor biology. With this information, Dr. Rood was able to demonstrate that medulloblastoma depends on a crucial pathway, the eukaryotic initiation factor 4F protein synthesis pathway, resulting in the identification of a potential target for new treatments in medulloblastoma.

Ultimately, Dr. Rood found that proteomic analysis complements genomic characterization and the two can be used together to create a more complete understanding of tumor biology. Going forward, he hopes proteomic analysis will become common practice for studying all tumors, allowing tumors to be categorized and grouped together by protein makeup to help the field identify more effective therapies for all tumors.
