Looking for ‘help’ signals in the blood of newborns with HIE

An Massaro

“This data support our hypothesis that a panel of biomarkers – not a one-time test for a single biomarker – is needed to adequately determine the risk and timing of brain injury for babies with HIE,” says An N. Massaro, M.D.

Measuring a number of biomarkers over time that are produced as the body responds to inflammation and injury may help to pinpoint newborns who are more vulnerable to suffering lasting brain injury due to disrupted oxygen delivery and blood flow, according to research presented during the Pediatric Academic Societies 2019 Annual Meeting.

Hypoxic-ischemic encephalopathy (HIE) happens when blood and oxygen flow are disrupted around the time of birth and is a serious birth complication for full-term infants. To lessen the chance of these newborns suffering permanent brain injury, affected infants undergo therapeutic cooling, which temporarily lowers their body temperatures.

“Several candidate blood biomarkers have been investigated in HIE but we still don’t have one in clinical use.  We need to understand how these markers change over time before we can use them to direct care in patients,” says An N. Massaro, M.D., co-director of the Neonatal Neurocritical Care Program at Children’s National and the study’s senior author. “The newborns’ bodies sent out different ‘help’ signals that we detected in their bloodstream, and the markers had strikingly different time courses. A panel of plasma biomarkers has the potential to help us identify infants most in need of additional interventions, and to help us understand the most optimal timing for those interventions.”

Past research has keyed in on inflammatory cytokines and Tau protein as potential biomarkers of brain injury for infants with HIE who are undergoing therapeutic cooling. The research team led by Children’s faculty wanted to gauge which time periods to measure such biomarkers circulating in newborns’ bloodstreams. They enrolled 85 infants with moderate or severe HIE and tapped unused blood specimens that had been collected as cooling began, as well as 12, 24, 72 and 96 hours later. The infants’ mean gestational age was 38.7 weeks, their mean birth weight was about 7 pounds (3.2 kilograms), and 19% had severe brain disease (encephalopathy).

Cytokines – chemicals like Interleukin (IL) 6, 8 and 10 that regulate how the body responds to infection, inflammation and trauma – peaked in the first 24 hours of cooling for most of the newborns. However, the highest measure of Tau protein for the majority of newborns was during or after the baby’s temperature was restored to normal.

“After adjusting for clinical severity of encephalopathy and five-minute Apgar scores, IL-6, IL-8 and IL-10 predicted adverse outcomes, like severe brain injury or death, as therapeutic hypothermia began. By contrast, Tau protein measurements predicted adverse outcomes during and after the infants were rewarmed,” Dr. Massaro says.

IL-6 and IL-8 proteins are pro-inflammatory cytokines while IL-10 is considered anti-inflammatory.  These chemicals are released as a part of the immune response to brain injury. Tau proteins are abundant in nerve cells and stabilize microtubules.

“This data support our hypothesis that a panel of biomarkers – not a one-time test for a single biomarker – is needed to adequately determine the risk and timing of brain injury for babies with HIE,” she adds.

Parents of older, healthier newborns with less social support less resilient

Ololade Okito

“We know that having a child hospitalized in the NICU can be a high-stress time for families,” says Ololade Okito, M.D., lead author of the cross-sectional study. “The good news is that as parental resiliency scores rise, we see a correlation with fewer symptoms of depression and anxiety.

Parents of older, healthier newborns who had less social support were less resilient during their child’s hospitalization in the neonatal intensive care unit (NICU), a finding that correlates with more symptoms of depression and anxiety, according to Children’s research presented during the Pediatric Academic Societies 2019 Annual Meeting.

Resiliency is the natural born, yet adaptable ability of people to bounce back in the face of significant adversity. Published research indicates that higher resilience is associated with reduced psychological distress, but the phenomenon had not been studied extensively in parents of children hospitalized in a NICU.

“We know that having a child hospitalized in the NICU can be a high-stress time for families,” says Ololade Okito, M.D., lead author of the cross-sectional study. “The good news is that as parental resiliency scores rise, we see a correlation with fewer symptoms of depression and anxiety. Parents who feel they have good family support also have higher resilience scores.”

The project is an offshoot of a larger study examining the impact of peer mentoring by other NICU parents who have experienced the same emotional rollercoaster ride as their tiny infants sometimes thrived and other times struggled.

The research team enrolled 35 parents whose newborns were 34 weeks gestation and younger and administered a battery of validated surveys, including:

  • The Connor-Davidson Resilience Scale
  • State-Trait Anxiety Inventory
  • Multidimensional Scale of Perceived Social Support
  • Edinburgh Postnatal Depression Scale and
  • Parent Stress Scale – NICU

Forty percent of these parents had high resilience scores; parents whose infants were a mean of 27.3 gestational weeks and who had more severe health challenges reported higher resilience. Another 40% of these parents had elevated depressive symptoms, while 31% screened positive for anxiety. Parental distress impairs the quality of parent-child interactions and long-term child development, the research team writes.

“Higher NICU-related stress correlates with greater symptoms of depression and anxiety in parents,” says Lamia Soghier, M.D., MEd, medical director of Children’s neonatal intensive care unit and the study’s senior author. “Specifically targeting interventions to these parents may help to improve their resilience, decrease the stress of parenting a child in the NICU and give these kids a healthier start to life.”

Billie Lou Short and Kurt Newman at Research and Education Week

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.”

The Rare Disease Institute staff on Rare Disease Day

Genetics 101: Rare diseases aren’t rare

The Rare Disease Institute staff on Rare Disease Day

Children’s National Health System is home to the Rare Disease Institute, the National Organization for Rare Disease’s first Center of Excellence, the largest clinical genetics program in the United States.

With the advent of DNA databanks, informatics, new technology, pediatric consortiums and global partnerships, clinical researchers have never been in a better position to diagnose and treat rare diseases. A rare disease is categorically defined as a condition that affects less than 200,000 people. However, 25 to 30 million Americans, about one in 10, have a rare disease.

Accelerations in genetic research and diagnostic criteria remain one of the most significant accomplishments in medicine, but these breakthroughs invite new challenges: How will researchers provide ongoing care and treatment for patients navigating a rare disease? How can doctors and researchers multiply themselves to ensure everyone has the latest information and resources they need? How can researchers use existing trials to augment other fields? How can we diagnose, catalogue and treat hundreds of new rare diseases each year, while accelerating the research and care of 7,000 existing rare conditions?

If these questions intrigue you, excite you and make you want to collaborate with scientific peers, welcome to the field of genetics. A common theme researchers and families talk about is that rare diseases affect a small proportion of the population, but have a huge impact.

On April 10, 1,200 international researchers, lawmakers, scientists and drug developers from 50 countries will meet in Oxon Hill, Md., 10 miles south of Washington, for a three-day summit, the World Orphan Drug Congress USA, to discuss how to unify efforts to enhance and maximize care for rare disease patients.

Here are eight themes to keep in mind:

    1. Rare diseases are chronic diseases. The human genome project has enabled the molecular mapping of 8,000 diseases with genetic underpinnings. Of these diseases, 600 diseases have therapies. A child born with a urea cycle disorder had a 5% chance of surviving the disease 40 years ago. Now the survival rate is 95%. Helping children survive is essential, but we need to think about the best treatments and standards for long-term care.
    2. Rare diseases are expensive. In Western Australia, according to the 2010 Western Australia Population Cohort, rare diseases account for less than 5% of hospital visits but for 10% of hospital costs. Similar data from Cleveland finds one-third of pediatric hospital visits have a genetic link but account for half of hospital costs.
    3. Rare diseases share common links. We’ve diagnosed 7,000 rare diseases but there are more to unravel. For example, breast cancer has over 30 molecular subtypes – some of which turn into rare diseases. By better understanding these molecular pathways, we may be able to inform common fields of medicine.
Marshall Summar's Rare Disease 101 presentation

Dr. Marshall Summar, a medical geneticist, speaks about the future of rare disease research and treatment at a Rare Disease 101 lecture hosted by the Rare Disease Congressional Caucus on Capitol Hill on Feb. 27. To sustain discoveries, Dr. Summar mentions a digital-first, flexible mindset is essential. Standard language and scalable, universal reference structures are required.

  1. Global partnerships create research repositories. Gold-standard research models – double blind, controlled studies with numerous participants – aren’t possible if five people in the world share the same disease. To increase the number of study participants, global partnerships and longitudinal registries are essential.
  2. Standard language helps. To avoid replicating existing research and to help teams quickly reference findings, we need to adopt standardized language to quantify measurements. Researchers from Berlin and Brazil may help inform the etiology of and future treatments for PKU, but they need to manage, store, access and share their collective findings, while remaining flexible.
  3. The science is here. The FDA is approving more drugs for rare diseases than ever before including gene therapy and micro organs, or Rare Diseases-on-chip models. The challenge with treating so many rare diseases isn’t developing new research, but creating therapies and studies to accommodate this patient volume. About 250 rare disease discoveries happen each year. At the current rate, it will take 2,000 years to treat them all.
  4. Progress is here. The Orphan Drug Act fast-tracked approval for rare disease treatments and therapies, and nearly half of all drugs coming in for FDA approval are for rare diseases. However, only 5% of rare diseases have FDA-approved drugs.
  5. We need to replicate geneticists. To provide optimal care, doctors need to standardize education models and use new forms of technology, such as artificial intelligence and deep learning, to share resources faster via patient education portals, resources for families, CME courses and virtual connections with pediatricians or families.

If you would like to learn more or get involved, watch this international summit, the Rare Disease Day Policy Event, which took place at the United Nations Headquarters in New York on Feb. 21. (Some of these issues are covered in video 4.)

If you live in Washington, D.C., follow the genetics team and consider working with us as we move into a new home, the Children’s National Research and Innovation Campus, in 2020.

ACC19 attendees from Children's National

ACC.19: A focus on pediatric cardiology

ACC19 attendees from Children's National

Dr. Gerard Martin, center, accepts an award before delivering the 2019 Dan G. McNamara Keynote lecture at ACC.19.

“Innovation meets tradition,” is how many attendees and journalists described the American College of Cardiology’s 68th Scientific Sessions (ACC.19), which took place March 16-18, 2019 in New Orleans, La.

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 hypoplastic 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.”

Test tube that says IGF-1 test

A new algorithm: Using genomics and EHR to detect severe growth disorders

Test tube that says IGF-1 test

Andrew Dauber, M.D., MMSc., a pediatric endocrinologist and the chief of endocrinology at Children’s National, guided research presented at ENDO 2019, the Endocrine Society’s annual meeting, enabling clinicians and researchers to understand the genetic underpinnings of certain pediatric growth disorders, while using electronic health record (EHR) algorithms to screen for presenting symptoms in the exam room. In some cases, this prompts further genetic testing and shortens the diagnostic odyssey for pediatric growth disorders – such as Turner syndrome.

Here is a summary of the research findings, delivered as two oral abstracts and a poster session.

ABSTRACT 1: Presented on Saturday, March 23, at 12:30 p.m. CST

Healthy childhood growth cohort provides insight into PAPPA2 and IGF-1 relationship, revealing a new level of complexity to the biology of growth with implications for the study and treatment of severe growth disorders

Program: Growth, puberty, and insulin action and resistance

Session OR07-5: A Cross-Sectional Study of IGF-I Bioavailability through Childhood: Associations with PAPP-A2 and Anthropometric Data

Background: Insulin-like growth factor 1 (IGF-1) is a hormone essential for human growth and is often bound to IGFBP-3, an IGF binding protein. Pregnancy Associated Plasma Protein-A2 (PAPP-A2) cleaves intact IGFBP-3, freeing IGF-1 to support normal growth functions. This is the first study, led by Dr. Andrew Dauber with collaborators from Cincinnati Children’s Hospital Medical Center, to track PAPP-A2 and intact IGFBP-3 concentrations throughout childhood. The research team studied 838 healthy children, ages 3-18, in the Cincinnati Genomic Control Cohort, to better understand patterns of growth and development by examining the relationship between PAPPA2 and IGF-1 bioavailability.

Study results: Free IGF-1 increased with age. PAPP-A2, a positive modulator of IGF-1 bioavailability, decreased with age, which surprised the researchers, and is not positively associated with absolute levels of free IGF-1. However, higher levels of PAPP-A2 cleave IGFBP-3 resulting in lower levels of intact IGFBP-3, and consequently, increasing the percentage of free to total IGF-1. This demonstrates that PAPP-A2 is a key regulator of IGF-1 bioavailability on a population-wide scale.

Impact: This research may help endocrinologists create unique, targeted treatment for children with PAPPA2 mutations and could help stratify patients with potential risk factors, such as IGF-1 resistance due to increased binding of IGF-1, associated with severe growth and height disorders. See adjoining study below.

ABSTRACT 2: Presented on Saturday, March 23, at 12:45 p.m. CST

Electronic health records can alert physicians to patients who could benefit from genetic testing to identify severe growth disorders

Program: Growth, puberty, and insulin action and resistance

Session OR07-6: Integrating Targeted Bioinformatic Searches of the Electronic Health Records and Genomic Testing Identifies a Molecular Diagnosis in Three Patients with Undiagnosed Short Stature

Background: Despite referrals to pediatric endocrinologists and extensive hormonal analysis, children with short stature due to a genetic cause, may not receive a diagnosis. Electronic health records may help identify patients – based on associated phenotypes and clinical parameters – who could benefit from genetic testing.

Study results: Researchers from three children’s hospitals – Boston Children’s Hospital, Children’s Hospital of Philadelphia and Cincinnati Children’s Hospital Medical Center – gathered data, starting small, with a known variable, or phenotype, associated with severe growth disorders: insulin-like growth factor 1 (IGF-1) resistance. A targeted bioinformatics search of electronic health records led the team to identify 39 eligible patients out of 234 candidates who met the criteria for a possible genetic-linked growth disorder. Participants were included if their height fell below two standard deviations for age and sex and if their IGF-1 levels rose above the 90th percentile. Patients who had a chronic illness, an underlying genetic condition or precocious puberty were excluded. Whole-exome sequencing (WES) was performed on DNA extracted from willing participants, including 10 patients and their immediate family members. The research team identified new genetic causes in three out of 10 patients with severe growth disorders, who were previously missed as having a genetic-linked growth disorder.

Note: Two patients had two novel IGF1R gene variants; a third had a novel CHD2 variant (p. Val540Phe). The two patients with IGF1R variants had a maternally inherited single amino acid deletion (p.Thr28del) and a novel missense variant (p. Val1013Phe).

Impact: Similar EHR algorithms can be replicated to identify pediatric patients at risk for or thought to have other genetic disorders, while expanding genetic research and improving patient care.

Electronic health record alerts could help detect Turner syndrome, shorten diagnostic odyssey for girls born with a missing or partially-deleted X chromosome

Program: Session P54. Pediatric puberty, ovarian function, transgender medicine and obesity

Poster Board #MON-249: Algorithm-Driven Electronic Health Record Notification Enhances the Detection of Turner Syndrome

Background: Turner syndrome (TS) results from a complete or partial loss of the second X chromosome and affects about one in every 2,500 female births. TS is common in females with unexplained short stature, but the diagnosis is often not made until late childhood (8-9 years), leading to delays in treatment and screening for comorbidities, such as heart conditions, chronic ear infections, vision problems and challenges with non-verbal learning. Using electronic health record (EHR) alarms can help clinicians screen for and diagnose TS patients earlier in life.

Study results: Researchers from Cincinnati Children’s Hospital Medical Center searched EHRs for female patients with idiopathic short stature who met the team’s selection criteria: Their height fell below two standard deviations from the mean for age as well as one standard deviation below the mid-parental height, had a BMI greater than 5 percent and did not have a chronic illness. The search produced 189 patients who met the diagnostic criteria, 72 of whom had not received prior genetic testing. Out of genetic samples available, 37 were compatible for a microarray analysis – which helped the team identify two cases of TS and a third chromosomal abnormality, all of which were missed by routine clinical evaluation.

Impact: DNA samples may not be available for all patients, but clinicians and researchers can identify and integrate tools into EHR’s – creating their own algorithms. An example includes setting up alerts for specific growth parameters, which helps identify and screen patients for TS.

The abstracts Dr. Dauber and his team discuss at ENDO 2019 support ongoing research, including a partnership among four leading children’s hospitals – Children’s National Health System, Boston Children’s Hospital, Children’s Hospital of Philadelphia and Cincinnati Children’s Medical Center – funded by an R01 grant to study how electronic health records can detect and identify novel markers of severe growth disorders.

The researchers hope their findings will also identify and help screen for comorbidities associated with atypical growth patterns, supporting multidisciplinary treatment throughout a child’s life. The study started in August 2018 and includes three sets of unique diagnostic criteria and will analyze WES from dozens of patients over five years.

Prescription for a healthy heart: pediatric-driven partnerships

Dr. Martin and a patient share a smile after a visit at Children’s National Health System.

For pediatric cardiologists, February, National Heart Month, is a special time. We share health tips in the hospital and talk about heart health with those looking for advice, especially with patients and families impacted by congenital heart disease (CHD). It’s also a time to look back at what’s worked well in the field, while accelerating advancements for CHD treatment.

To start, congenital heart disease, a structural abnormality of the heart or of the blood vessels surrounding it, is the most common birth defect and occurs in about one in every 100 live births, affecting 40,000 babies born in the U.S. each year. One million children and 1.4 million adults in the U.S. have CHD. Over the past 15 years, pediatric cardiologists have cut mortality rates for CHD in half. Gratefully, now instead of saving children’s lives, the emphasis is on improving them. The catalyst for this paradigm shift isn’t simply due to a medical breakthrough, but is also the result of collaboration and advocacy.

Pediatric cardiologists worked together with other stakeholders – nurses, neonatologists, parents, state and federal agencies – to implement newborn screening methods in hospitals, with the introduction pulse oximetry screenings for critical congenital heart defects (CCHD). The screening, which measures blood oxygen levels in newborns, focuses on screening babies for CCHD before they leave the hospital. The concept and a national protocol for screening began with a small project in 2002, was endorsed by medical associations by 2012 and required by all states in 2018. The impact of CCHD screening of newborns is remarkable. Data published in JAMA showed a 33 percent reduction in CCHD infant deaths associated with states that required CCHD screening.

The pulse oximetry screening’s impact on the number of lives saved goes beyond identifying newborns with CCHD. Worldwide, though the detection of secondary conditions, such as hypothermia, pneumonia, and sepsis, the pulse oximetry screening is estimated to save roughly 772,000 lives by 2030.

In addition to newborn screening recommendations for CCHD, a group of cardiologists, including myself, worked for the Joint Council on Congenital Heart Disease (JCCHD) to form and support the National Pediatric Cardiology Quality Improvement Collaborative (NPC-QIC). We developed measures to see how we could improve survival rates between surgeries for infants born with hypoplastic left heart syndrome (HLHS), one of the most common and severe forms of CCHD.

Babies born with HLHS require two heart surgeries within the baby’s first six months. Babies that survived the first operation had a significant mortality rate (15 percent) and frequent growth failure, while waiting for the second operation. Our focused aims were to both decrease the death rate and improve growth in these children. We analyzed data from medical centers, utilized quality improvement principals from the Institute for Health Care Improvement, talked with doctors and families, and invited teams from across the U.S. to partner with us to put quality and safety measures into place.

We emphasized the following points:

  1. Clear communication. Parents leaving the hospital received consistent messages about CHD, the type of surgery their baby had, next steps and how to care for their child at home.
  2. Improved nutrient intake. Parents received clear guidelines about how many calories babies needed to consume, were asked to weigh their baby each day, and taught how to augment feeding.
  3. Warning signs.Parents received a list of typical infant behaviors and HLHS red flags to watch out for, such as if a baby isn’t gaining a certain amount of weight. They received monitors to measure oxygen saturation levels at home. If oxygen saturation dropped significantly or if parents noticed a problem, they called their doctor immediately.

The implementation of these procedures reduced interstage mortality rates and the number of growth failures for HLHS patients. In 2008, six centers participated in the NPC-QIC pilot. By 2018, 65 medical centers in the U.S. and Canada used these methods. Similar to the pulse oximetry screening guidelines, this new method wasn’t the result of a medical breakthrough, but the result of shared learning and shared infrastructure.

Now, we’re referring more adult congenital heart patients to board-certified adult congenital heart disease (ACHD) specialists, a better fit than internists or pediatric cardiologists. Adults with congenital heart defects should have their heart examined at least once by a specialist and those with complex needs should meet with a specialist at least every two years. More than 300 board-certified ACHD specialists practice in the U.S. and the field is growing. The third ACHD board exam takes place this year.

Over the next few decades, I hope we’ll make even more progress with understanding, diagnosing and treating CHD.

Emerging research examines genetic clues for congenital heart defects, which were once thought to account for 8 percent of cases and may now account for 30 percent of conditions. We’re working with neurologists to examine the timing and pathway of potential oxygen inefficiencies that occur as the brain develops in utero, infancy, and after neonatal surgery. We’ve come a long way, but we continue looking at new frontiers and for innovative solutions.

Fortunately, as cardiologists, we’re good at fixing problems. We work with surgeons and medical teams to repair holes in hearts, or replace them, and reroute blood from an underdeveloped left ventricle to improve circulation. For almost every heart defect, we have evidence-based solutions. However, to continue to help children worldwide, it’s imperative that we don’t forget about what works well: good science, tracking data, sharing best practices, active listening, transparency and constant collaboration.

Maureen E. Lyon receives American Cancer Society grant

Maureen E Lyon

Children’s Clinical Health Psychologist Maureen E. Lyon, Ph.D., has received the “Judy White Memorial Clinical Research Pilot Exploratory Projects in Palliative Care of Cancer Patients and their Families” grant from the American Cancer Society (ACS).

Over two years, Lyon will be allotted $144,000 to translate Children’s evidence-based Family-Centered (FACE) pediatric advance care planning (ACP) protocol into Spanish through a process of community-based participatory research for teens with cancer.

Lyon’s research focuses on enabling families to understand their adolescents’ treatment preferences and describing patient-reported palliative care needs for teens with cancer. Ultimately, the research will help identify the wants, values, goals and beliefs of teens with cancer.

Along with the ACS research grant, Lyon and Jessica Thompkins, BSN, R.N., CPN, research nurse coordinator at Children’s National, will present at the Annual Assembly of Hospice & Palliative Medicine conference, March 13-16, 2019 in Orlando, Fla. on data from the current multi-site, five-year randomized clinical trial funded by National Institute of Health/ National Institute of Nursing Research for English-speaking teens with cancer.

During the presentation, they will speak about the effect of FACE ACP on families’ appraisals of caregiving for their teens with cancer and describing advance care planning communication approaches.

Lyon and other researchers at Children’s National look forward to making significant contributions to the science of advance care planning aimed to minimize suffering and enhancing quality of life for young adults. Their contributions give teens a voice in their future medical care and help families “break the ice,” by providing an extra level of support to treating clinicians.

Newborns with suspected food allergies breastfed significantly longer

toddler nursing

Mothers whose newborns had suspected food allergies reported breastfeeding them significantly longer than women whose infants had no adverse reactions after food exposure, according to preliminary research led by Karen A. Robbins, M.D., and presented during the American Academy of Allergy, Asthma & Immunology 2019 Annual Meeting.

According to the Centers for Disease Control and Prevention (CDC), food allergies affect 4 to 6 percent of U.S. children, making such allergies a growing public health concern. Researchers are attempting to learn more about the interplay between food allergies and what, when and how children eat to inform allergy-prevention efforts. Little is known about the association between perceived food allergies, intolerance or hypersensitivity among babies eating their first bites of solid food and how long they’re breastfed.

Dr. Robbins and colleagues analyzed data gathered through a longitudinal study led by the Food and Drug Administration (FDA) and the CDC from 2005 to 2007. The Infant Feeding Practices Study II tracked diet and feeding practices of about 2,000 women late in their pregnancies and followed their babies’ diets through the first year of life.

Some 2,586 breastfeeding mothers in the study completed surveys when their infants were 4, 9 and 12 months old. The women were asked whether there were problems caused by food, such as an allergic reaction, sensitivity or intolerance. The majority of these infants (84.6 percent) had no suspected allergic reaction to either food they ate on their own or to food they were exposed to via breastmilk. The mothers reported that nearly 11 percent of infants reacted to something they ate; 2.4 percent reacted to food products they were exposed to via breastmilk; and 2.4 percent reacted to both food they consumed directly or were exposed to via breastfeeding. They also found:

  • Infants with suspected food allergies after exposure to food their mothers ate were breastfed a mean of 45.8 weeks.
  • Infants with food intolerance after both exposure to food their mother consumed and food they ate themselves were breastfed a mean of 40.2 weeks.

That contrasts with infants with no concern for food reactions, who were breastfed a mean of 32 weeks.

“Breastfeeding a newborn for the first few months of life helps their developing immune system become more robust, may affect the microbiome, and could influence or prevent development of allergy later in life,” says Dr. Robbins, an allergist at Children’s National Health System and lead author of the research. “However, mothers’ perceptions of their newborns’ adverse reactions to food appears to factor into how long they breastfeed.”

One potential concern is that extended breastfeeding can impact solid food introduction practices.

“Gradually transitioning to solid food gives infants an opportunity to sample an array of foods, nibble by nibble, including food allergens like peanut and eggs. We know from previously published research that introducing high-risk babies to a food allergen like peanuts early in life appropriately primes their immune system and dramatically decreases how often these children actually develop peanut allergies,” Dr. Robbins adds. “The relationship between breastfeeding and allergy development is complex, so understanding mothers’ practices is important. We also do not know how often these early reactions result in true food allergy, compared with transient food intolerance.”

Exclusive breastfeeding lowers odds of some schoolchildren having eczema

Breastfeeding Mom

Children exclusively breastfed for the first three months of life had significantly lower odds of having eczema at age 6 compared with peers who were not breastfed or were breastfed for less time, according to preliminary research presented during the American Academy of Allergy, Asthma & Immunology 2019 Annual Meeting.

Eczema is a chronic condition characterized by extremely itchy skin that, when scratched, becomes inflamed and covered with blisters that crack easily. While genes and the environment are implicated in this inflammatory disease, many questions remain unanswered, such as how best to prevent it. According to the Centers for Disease Control and Prevention (CDC), breastfed infants have reduced risks for developing many chronic conditions, including asthma and obesity.

“The evidence that being exclusively breastfed protects children from developing eczema later in life remains mixed,” says Katherine M. Balas, BS, BA, a clinical research assistant at Children’s National and the study’s lead author. “Our research team is trying to help fill that data gap.”

Balas and colleagues tapped data collected in Infant Feeding Practices Study II, a longitudinal study co-led by the CDC and the Food and Drug Administration (FDA) from 2005 to 2007, as well as the agencies’ 2012 follow-up examination of that study cohort. This study first tracked the diets of about 2,000 pregnant women from their third trimester and examined feeding practices through their babies’ first year of life. Their follow-up inquiry looked at the health, development and dietary patterns for 1,520 of these children at 6 years of age.

About 300 of the children had been diagnosed with eczema at some point in their lives, and 58.5 percent of the 6-year-olds had eczema at the time of the CDC/FDA Year Six Follow-Up. Children with higher socioeconomic status or a family history of food allergies had higher odds of being diagnosed with eczema.

“Children who were exclusively breastfed for three months or longer were significantly less likely (adjusted odds ratio: 0.477) to have continued eczema at age 6, compared with peers who were never breastfed or who were breastfed for less than three months,” Balas adds. “While exclusive breastfeeding may not prevent kids from getting eczema, it may protect them from experiencing extended flare-ups.”

Food allergies: a research update

Assorted foods

Promising new therapies for food allergies are on the horizon, including an experimental immunotherapy awaiting federal approval that enables people who are very allergic to eat peanut protein without suffering serious side effects.

Good news, right?

As it turns out, the idea of a child who is highly allergic to a specific food eating that same food item makes kids with lifelong food allergies and their parents a bit queasy.

“It’s a very big paradigm shift. From diagnosis, children are told to avoid their food triggers at all cost. But now they may be counseled to approach the very thing that scares them, put it in their body and see what happens,” says Linda Herbert, Ph.D., an assistant professor in Children’s Division of Psychology and Behavioral Health.

“On the flip side, these new protections could reduce long-term anxieties, replacing daily anxiety about accidental exposure with a newfound sense of empowerment. Either way, a lot of families will need support as they try these new treatments that enable them to ingest a food allergen daily or wear a patch that administers a controlled dose of that food allergen,” Herbert says.

She will discuss food allergy treatments in the pipeline and families’ psychosocial concerns related to daily life as she presents a research update during the American Academy of Allergy, Asthma & Immunology (AAAAI) 2019 Annual Meeting. A select group, including Herbert, has been recognized with an AAAAI Foundation Heritage Lectureship, which honors distinguished AAAAI members with a special lecture and plaque.

Herbert’s symposium targets allied health professionals at the annual meeting, including psychologists, dietitians and nurse practitioners who attend to a host of psychosocial concerns felt by families affected by allergies to foods like eggs, nuts and cow’s milk.

“When patients arrive for outpatient therapy, they feel anxious about being safe when they’re out in public. They have anxieties about their children feeling safe at school as well as managing restaurant meals. They explain difficulties being included in social events like birthday parties, field trips and shared vacations,” Herbert says. “Some families restrict social activities due to stress and anxiety.”

Children’s National Health System takes a multidisciplinary approach for complex conditions like food allergies, she says, combining the expertise of psychologists, medical providers, research nurses, clinical nurses, registered dietitians and other allied health professionals.

“When we all communicate, we can see the complete picture. It strengthens the care that the child receives, and it’s especially powerful that it can happen all at once – rather than going to multiple appointments,” she adds.

During such group huddles, the team agrees on a plan together that is communicated to the family. One ongoing challenge is that one-third of school children with food allergies are bullied or teased.

“A lot of parents don’t necessarily know to ask or how to ask. I frequently suggest that clinicians discuss peer concerns more in clinic.”

Neurodevelopmental disorders: Developing medical treatments

Vittorio Gallo

Vittorio Gallo, Ph.D., Chief Research Officer, participates in the world’s largest general scientific gathering, leading panelists in a timely conversation about progress made so far with neurodevelopmental disorders and challenges that lie ahead.

The human brain is the body’s operating system. Imagine if rogue code worked its way into its hardware and software, delaying some processes, disrupting others, wreaking general havoc.

Neurodevelopmental disorders are like that errant code. They can occur early in life and impact brain development for the rest of the person’s life. Not only can fundamental brain development go awry, processes that refine the brain also can become abnormal, creating a double neural hit.  Adding to those complications, children with neurodevelopmental disorders like autism spectrum disorder (ASD) and Fragile X syndrome often contend with multiple, overlapping cognitive impairments and learning disabilities.

The multiple layers of complexities for these disorders can make developing effective medical treatments particularly challenging, says Vittorio Gallo, Ph.D., Chief Research Officer at Children’s National Health System and recipient of a coveted Senator Jacob Javits Award in the Neurosciences.

During the Feb. 16, 2019, “Neurodevelopmental Disorders: Developing Medical Treatments” symposium, Gallo will guide esteemed panelists in a timely conversation about progress made so far and challenges that lie ahead during the AAAS Annual Meeting in Washington, the world’s largest general scientific gathering.

“This is a very important symposium; we’re going to put all of the open questions on the table,” says Gallo. “We’re going to present a snapshot of where the field is right now: We’ve made incredible advances in developmental neuroscience, neonatology, neurology, diagnostic imaging and other related fields. The essential building blocks are in place. Where are we now in developing therapeutics for these complex disorders?”

For select disorders, many genes have been identified, and each new gene has the potential to become a target for improved therapies. However, for other neurodevelopmental disorders, like ASD, an array of new genes continue to be discovered, leaving an unfinished picture of which genetic networks are of most importance.

Gallo says the assembled experts also plan to explore major research questions that remain unanswered as well as how to learn from past experiences to make future studies more powerful and insightful.

“One topic up for discussion will be new preclinical models that have the potential to help in identifying specific mechanisms that cause these disorders. A combination of genetic, biological, psychosocial and environmental risk factors are being combined in these preclinical models,” Gallo says.

“Our studies of the future need to move beyond describing and observing in order to transform into studies that establish causality between the aberrant developmental processes and these constellations of neurodevelopmental disorders.”

Randi Streisand, Ph.D., chief of Psychology and Behavioral Health at Children’s National Health System, will be honored with the Michael C. Roberts Award for Outstanding Mentorship by the  Society of Pediatric Psychology (SPP), a Division of the American Psychological Association. This award honors pediatric psychology faculty who go above and beyond to mentor students and provide professional advice and guidance through students’ various training phases.

The Society of Pediatric Psychology will present the award at their Annual Conference held on Apr. 4-6, 2019 in New Orleans, La.

Streisand was selected for the award based on her exceptional mentorship in the areas of research, clinical work and overall career development through graduate school, postdoctoral fellowships and early career stages.

“I’m very honored to be selected for this distinguished award,” says Streisand. “Working with students, fellows and junior faculty members has been the highlight of my career. I really enjoy helping guide people on their own career paths. I have been fortunate to mentor many truly talented individuals, several of whom I now get to work with as valued colleagues.”

Streisand has served as a primary mentor on funded career development awards, research fellowships and dissertations. Her impressive track record of mentoring behavioral researchers has benefited six faculty members by moving Children’s fellows into tenure-track and clinical faculty positions. Furthermore, her research assistants have been accepted into leading graduate programs in psychology and health including the University of Florida, Loyola University Chicago, Georgia State University and UT Southwestern Medical Center.

“Dr. Streisand’s approach to mentorship is comprehensive, and she goes the extra mile for each intern, colleague and researcher she works with,” says Roger J. Packer, M.D., senior vice president at Children’s Center of Neuroscience and Behavioral Medicine. “She has already made a major impact on the field of pediatric psychology through her superb mentorship and will continue to do so for the years to come.”

mitochondria

Treating nephrotic-range proteinuria with tacrolimus in MTP

mitochondria

Mitochondria are the cell’s powerplants and inside them the MTP enzymatic complex catalyzes three steps in beta-oxidation of long-chain fatty acids.

In one family, genetic lightning struck twice. Two sisters were diagnosed with mitochondrial trifunctional protein (MTP) deficiency. This is a rare condition that stops the body from converting fats to energy, which can lead to lactic acidosis, recurrent breakdown of muscle tissue and release into the bloodstream (rhabdomyolysis), enlarged heart (cardiomyopathy) and liver failure.

Mitochondria are the cell’s powerplants and inside them the MTP enzymatic complex catalyzes three steps in beta-oxidation of long-chain fatty acids. MTP deficiency is so rare that fewer than 100 cases have been reported in the literature says Hostensia Beng, M.D., who presented an MTP case study during the American Society of Nephrology’s Kidney Week.

The 7-month-old girl with known MTP deficiency arrived at Children’s National lethargic with poor appetite. Her laboratory results showed a low corrected serum calcium level, elevated CK level and protein in the urine (proteinuria) at a nephrotic range. The infant was treated for primary hypoparathyroidism and rhabdomyolysis.

Even though the rhabdomyolysis got better, the excess protein in the girl’s urine remained at worrisome levels. A renal biopsy showed minimal change disease and foot process fusion. And electron microscopy revealed shrunken, dense mitochondria in visceral epithelial cells and endothelium.

“We gave her tacrolimus, a calcineurin inhibitor that we are well familiar with because we use it after transplants to ensure patient’s bodies don’t reject the donated organ. By eight months after treatment, the girl’s urine protein-to-creatinine (uPCR) ratio was back to normal. At 35 months, that key uPCR measure rose again when tacrolimus was discontinued. When treatment began again, uPCR was restored to normal levels one month later,” Dr. Beng says.

The girl’s older sister also shares the heterozygous deletion in the HADHB gene, which provides instructions for making MTP. That missing section of the genetic how-to guide was predicted to cause truncation and loss of long-chain-3-hydroxyacl CoA dehydrogenase function leading to MTP deficiency.

The older sister was diagnosed with nephrotic syndrome and having scar tissue in the kidney’s filtering unit (focal segmental glomerulosclerosis) when she was 18 months old. By contrast, she developed renal failure and progressed to end stage renal disease at 20 months of age.

“Renal involvement has been reported in only one patient with MTP deficiency to date, the older sister of our patient,” Dr. Beng adds.

Podocytes are specialized cells in the kidneys that provide a barrier, preventing plasma proteins from leaking into the urine. Podocytes, however, need energy to function and are rich in mitochondria.

“The proteinuria in these two sisters may be related to their mitochondrial dysfunction. Calcineurin inhibitors like tacrolimus have been reported to reduce proteinuria by stabilizing the podocyte actin cytoskeleton. Tacrolimus was an effective treatment for our patient, who has maintained normal renal function, unlike her sister,” Dr. Beng says.

Getting micro-preemie growth trends on track

Preemie Baby

According to Children’s research presented during the Institute for Healthcare Improvement 2018 Scientific Symposium, standardizing feeding practices – including the timing for fortifying breast milk and formula with essential elements like zinc and protein – improves growth trends for the tiniest preterm infants.

About 1 in 10 infants is born before 37 weeks gestation. These premature babies have a variety of increased health risks, including deadly infections and poor lung function.

Emerging research suggests that getting their length and weight back on track could help. According to Children’s research presented during the Institute for Healthcare Improvement 2018 Scientific Symposium, standardizing feeding practices – including the timing for fortifying breast milk and formula with essential elements like zinc and protein – improves growth trends for the tiniest preterm infants.

The quality-improvement project at Children’s National Health System targeted very low birth weight infants, who weigh less than 3.3 pounds (1,500 grams) at birth. These fragile infants are born well before their internal organs, lungs, brain or their digestive systems have fully developed and are at high risk for ongoing nutritional challenges, health conditions like necrotizing enterocolitis (NEC) and overall poor development.

The research team measured progress by tracking the micro-preemies’ mean delta weight Z-score for weight gain, which measures nutritional status.

“In this cohort, mean delta weight Z-scores improved by 43 percent, rising from -1.8 to the goal of -1.0, when we employed an array of interventions. We saw the greatest improvement, 64 percent, among preterm infants who had been born between 26 to 28 weeks gestation,” says Michelande Ridoré, MS, Children’s NICU quality-improvement program lead who presented the group’s preliminary findings. “It’s very encouraging to see improved growth trends just six months after introducing these targeted interventions and to maintain these improvements for 16 months.”

Within Children’s neonatal intensive care unit (NICU), micro-preemies live in an environment that mimics the womb, with dimmed lighting and warmed incubators covered by blankets to muffle extraneous noise. The multidisciplinary team relied on a number of interventions to improve micro-preemies’ long-term nutritional outcomes, including:

  • Reducing variations in how individual NICU health care providers approach feeding practices
  • Fortifying breast milk (and formula when breast milk was not available), which helps these extra lean newborns add muscle and strengthen bones
  • Early initiation of nutrition that passes through the intestine (enteral feeds)
  • Re-educating all members of the infants’ care teams about the importance of standardized feeding and
  • Providing a decision aid about feeding intolerance.

Dietitians were included in the daily rounds, during which the multidisciplinary team discusses each infant’s care plan at their room, and used traffic light colors to describe how micro-preemies were progressing with their nutritional goals. It’s common for these newborns to lose weight in the first few days of life.

  • Infants in the “green” zone had regained their birth weight by day 14 of life and possible interventions included adjusting how many calories and protein they consumed daily to reflect their new weight.
  • Infants in the “yellow” zone between day 15 to 18 of life remained lighter than what they weighed at birth and were trending toward lower delta Z-scores. In addition to assessing the infant’s risk factors, the team could increase calories consumed per day and add fortification, among other possible interventions.
  • Infants in the “red” zone remained below their birth weight after day 19 of life and recorded depressed delta Z-scores. These infants saw the most intensive interventions, which could include conversations with the neonatologist and R.N. to discuss strategies to reverse the infant’s failure to grow.

Future research will explore how the nutritional interventions impact newborns with NEC, a condition characterized by death of tissue in the intestine. These infants face significant challenges gaining length and weight.

Megan Young, M.D., has been named a 2019 Limb Lengthening and Reconstruction Society (LLRS) Traveling Fellow.

The fellowship provides leading education in limb lengthening and reconstruction, trains future leaders of LLRS and establishes mentor relationships between current society members and new surgeons.

“We are beyond proud that Dr. Young was selected for this highly competitive opportunity,” says Matthew Oetgen, M.D., chief of Orthopaedics and Sports Medicine. “This is only the latest recognition Dr. Young has received for her growing expertise in limb lengthening and complex lower extremity reconstructions.”

During her fellowship in August 2019, Dr. Young will travel to multiple limb lengthening and reconstruction surgical centers to share ideas and exchange best practices with orthopaedic surgeons at every career stage – from trainees to seasoned veterans. She will present her key takeaways from the experience at the society’s 2020 annual meeting.

Dr. Young has a special interest in caring for children with lower extremity deformity and limb length discrepancies and has developed a Limb Lengthening program at Children’s, which offers patients and their families comprehensive treatment options for these complex conditions using leading edge technology.

Lactobacillis-Bacteria

Does ZIP code factor into genitourinary system health?

Lactobacillis-Bacteria

Clinicians suspect that taking probiotics, such as lactobacillus supplements, and making changes to diet may prevent urinary diseases that occur commonly among pediatric patients. A research team led by Children’s faculty is exploring whether changes in the built environment also affect the urinary microbiome.

Emerging evidence suggests that the variety and volume of bacteria that reside in the bladder – the urinary microbiome – significantly impact whether people’s genitourinary systems remain healthy or become susceptible to disease.

Already, clinicians suspect that taking probiotics and making changes to diet may prevent urinary diseases that occur commonly among pediatric patients. A research team led by Children’s faculty is exploring whether changes in the built environment also affect the urinary microbiome.

Using experimental models, they looked at how stable the urinary microbiome was over time. Then, they measured the potential effect of changing the built environment on the urinary microbiome of preclinical models.

They did this by following six C57BL/6 experimental models for five months, starting from when they were nine weeks old. They collected urine specimens when the study began and repeated sample collections each month. The multidisciplinary team isolated microbial DNA from these specimens to determine the makeup of the bacterial community present in their urinary tracts.

All of the experimental models shared a single cage, drank the same water and ate the exact same chow. At four months, however, they moved the preclinical models to a different facility within the same county. Their chow and bedding remained unchanged, but the water source changed since they received tap water at both locations.

“There were no changes in the proportion of specific bacteria in the urinary microbiomes from month zero through month five, which means the urinary microbiomes of healthy experimental models remain stable over time,” says Michael Hsieh, M.D., Ph.D., a urologist at Children’s National Health System and senior author of the work presented during the Pediatric Urology Fall Conference. “However, the convergence of the Shannon Diversity Index, the clustering seen on Principal coordinate analyses and changes in functional analyses taken as a whole suggest that an overall shift of the urinary microbiome occurred due to a change in the physical environment.”

This work suggests that where patients live could influence which bacteria grow in the urinary tracts, including during urinary tract infections.
