Manuscripts, Articles, Book Chapters and Other Papers

INTRODUCTION: Minimal change disease in childhood can follow a frequently relapsing or steroid-dependent course in up to 40% of cases. Second-line immunosuppressive medications that are used to manage these patients are associated with significant adverse effects. There is a need for safer alternative treatments for difficult-to-treat nephrotic syndrome. Therefore, we conducted an open-label feasibility study to assess the safety and efficacy of a gluten-free diet as treatment for pediatric patients with difficult-to-treat nephrotic syndrome. As a second aim, we sought to determine if the plasma zonulin concentration can identify those who are more likely to respond to this intervention.

Psychosocial Considerations For The Child With Rare Disease: A Review With Recommendations And Calls To Action., Leslee Belzer, Margaret Wright, Emily J. Goodwin, Mehar N. Singh, Brian S. Carter

Manuscripts, Articles, Book Chapters and Other Papers

Rare diseases (RD) affect children, adolescents, and their families infrequently, but with a significant impact. The diagnostic odyssey undertaken as part of having a child with RD is immense and carries with it practical, emotional, relational, and contextual issues that are not well understood. Children with RD often have chronic and complex medical conditions requiring a complicated milieu of care by numerous clinical caregivers. They may feel isolated and may feel stigmas in settings of education, employment, and the workplace, or a lack a social support or understanding. Some parents report facing similar loneliness amidst a veritable medicalization of their …

Pharmacometabolomics Profiling Of Preterm Infants Validates Patterns Of Metabolism Associated With Response To Dexamethasone Treatment For Bronchopulmonary Dysplasia., Bradley Stockard, Cheri Gauldin, William E. Truog, Tamorah Lewis

Manuscripts, Articles, Book Chapters and Other Papers

Bronchopulmonary dysplasia (BPD) is one of the most common health complications of premature birth. Corticosteroids are commonly used for treatment of BPD, but their use is challenging due to variability in treatment response. Previous pharmacometabolomics study has established patterns of metabolite levels with response to dexamethasone. We obtained additional patient samples for metabolomics analysis to find associations between the metabolome and dexamethasone response in a validation cohort. A total of 14 infants provided 15 plasma and 12 urine samples. The measure of treatment response was the calculated change in respiratory severity score (deltaRSS) from pre-to-post treatment. Each metabolite was assessed …

Neutralization capacity of antibodies against Omicron after a prior SARS-CoV-2 infection in children and adolescents is not well studied. Therefore, we evaluated virus-neutralizing capacity against SARS-CoV-2 Alpha, Beta, Gamma, Delta and Omicron variants by age-stratified analyses (5 years of age. As expected, convalescent pediatric COVID-19 and MIS-C cohorts demonstrate higher neutralization titers than hospitalized acute COVID-19 patients. Overall, children and adolescents show some loss of cross-neutralization against all variants, with the most pronounced loss against Omicron. In contrast to SARS-CoV-2 infection, children vaccinated twice demonstrated higher titers against Alpha, Beta, Gamma, Delta and Omicron. These findings can influence transmission, re-infection …

Burnout In Pediatric Nephrology Fellows And Faculty: Lessons From The Sustainable Pediatric Nephrology Workforce Project (Superpower)., Susan M. Halbach, Kartik Pillutla, Patricia Seo-Mayer, Alan Schwartz, Darcy K. Weidemann, John D. Mahan

Manuscripts, Articles, Book Chapters and Other Papers

Physician well-being is an important contributor to both job satisfaction and patient outcomes. Rates of burnout among physicians vary by specialty, ranging from 35 to 70%. Among pediatric residents, longitudinal data demonstrates consistent rates of burnout around 50-60%, although little is known about burnout among pediatric subspecialty fellows. Specifically, the degree of burnout among pediatric nephrologists remains unknown, as does the impact faculty burnout may have on trainee burnout. We sought to evaluate prevalence and predictors of burnout among US pediatric nephrology fellows and faculty, and assess for interactions between groups. In this multi-center pilot survey of all United States …

Decreased Physical Activity Among Youth Resulting From Covid-19 Pandemic-Related School Closures: Natural Experimental Study., Amanda Grimes, Joseph S. Lightner, Katlyn Eighmy, Chelsea Steel, Robin P. Shook, Jordan A. Carlson

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: The COVID-19 pandemic has resulted in the closure of schools and may have inadvertently resulted in decreased physical activity for youth. Emerging evidence suggests that school closures due to the COVID-19 pandemic could have hastened the inactivity of youth, possibly due to a lack of structure outside of school and increased access to sedentary activities.

OBJECTIVE: The purpose of this study was to assess changes in physical activity from pre-school closure (before the pandemic) to post-school closure (during the pandemic) among youth in spring 2020.

METHODS: This study used a natural experimental design; youth were enrolled in a physical …

Access to paediatric neurology care is complex, resulting in significant wait times and negative patient outcomes. The goal of the American Academy of Pediatrics National Coordinating Center for Epilepsy's project, Access Improvement and Management of Epilepsy with Telehealth (AIM-ET), was to identify access and management challenges in the deployment of telehealth technology. AIM-ET organised four paediatric neurology teams to partner with primary-care providers (PCP) and their multidisciplinary teams. Telehealth visits were conducted for paediatric epilepsy patients. A post-visit survey assessed access and satisfaction with the telehealth visit compared to an in-person visit. Pre/post surveys completed by PCPs and neurologists captured …

Objective: To examine the associations between early and late CUS findings and infant neurobehavior at NICU discharge.

Design, Setting, and Participants: This prospective cohort study included infants enrolled in the Neonatal Neurobehavior and Outcomes in Very Preterm Infants Study between April 2014 and June 2016. Infants born before 30 weeks' gestational …

Pediatric Growth Patterns In Youth-Onset Type 2 Diabetes Mellitus: Implications For Physiologically-Based Pharmacokinetic Models., Chelsea M. Hosey, Kelsee Halpin, Valentina Shakhnovich, Chengpeng Bi, Brooke Sweeney, Yun Yan, J Steven Leeder

Manuscripts, Articles, Book Chapters and Other Papers

An accurate understanding of the changes in height and weight of children with age is critical to the development of models predicting drug concentrations in children (i.e., physiologically-based pharmacokinetic models). However, curves describing the growth of a typical population of children may not accurately characterize growth of children with various conditions, such as obesity. Therefore, to develop height and weight versus age growth curves for youth who were diagnosed with type 2 diabetes, we extracted data from electronic medical records. Robust nonlinear models were parameterized to the equations describing height and weight versus age as defined by the Centers for …

Obstructive Sleep Apnea In Neonates., Indira Chandrasekar, Mary Anne Tablizo, Manisha Witmans, Jose Cruz, Marcus Cummins, Wendy Estrellado-Cruz

Manuscripts, Articles, Book Chapters and Other Papers

Neonates have distinctive anatomic and physiologic features that predispose them to obstructive sleep apnea (OSA). The overall prevalence of neonatal OSA is unknown, although an increase in prevalence has been reported in neonates with craniofacial malformations, neurological disorders, and airway malformations. If remained unrecognized and untreated, neonatal OSA can lead to impaired growth and development, cardiovascular morbidity, and can even be life threatening. Polysomnography and direct visualization of the airway are essential diagnostic modalities in neonatal OSA. Treatment of neonatal OSA is based on the severity of OSA and associated co-morbidities. This may include medical and surgical interventions individualized for …

Down Syndrome-Associated Arthritis (Da): Diagnostic And Management Challenges., Jordan T. Jones, Jacqueline Kitchen, Nasreen Talib

Manuscripts, Articles, Book Chapters and Other Papers

Down syndrome (DS) is one of the most common birth defects in the United States, the most common genomic disorder of intellectual disability, and results from trisomy 21. This chromosome disorder causes an extensive, heterogenous phenotype that results in a broad presentation of symptoms that includes atlantoaxial instability, congenital heart defects, muscle hypotonia, hypothyroidism, hematologic disorders, recurrent infections, and autoimmune diseases. The autoimmune diseases are caused by immune system dysregulation that results in increased pro-inflammatory cytokines, along with other innate and adaptive immune system dysregulation. This is the likely cause of the increased risk of inflammatory arthritis or Down syndrome-associated …

Moving The Needle Toward Fair Compensation In Pediatric Nephrology., Darcy K. Weidemann, I A Ashoor, D E Soranno, R Sheth, C Carter, P D Brophy

Manuscripts, Articles, Book Chapters and Other Papers

Remuneration issues are a substantial threat to the long-term stability of the pediatric nephrology workforce. It is uncertain whether the pediatric nephrology workforce will meet the growing needs of children with kidney disease without a substantial overhaul of the current reimbursement policies. In contrast to adult nephrology, the majority of pediatric nephrologists practice in an academic setting affiliated with a university and/or children's hospital. The pediatric nephrology service line is crucial to maintaining the financial health and wellness of a comprehensive children's hospital. However, in the current fee-for-service system, the clinical care for children with kidney disease is neither sufficiently …

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Three-dimensional (3D) speckle tracking echocardiography (STE) can overcome some of the inherent limitations of two-dimensional (2D) STE; however, clinical experience is lacking. We aimed to assess and compare the feasibility, agreement, and reproducibility of left ventricular (LV) global longitudinal (GLS), and regional strain by 3D vs 2D STE in normal children.

METHODS: Healthy pediatric subjects (n = 105, age mean = 11.2 ± 5.5 years) were prospectively enrolled. Three-dimensional and 2D LV GLS, as well as regional strain in 16 myocardial segments were quantified. Bland Altman analysis, intra- class correlation coefficients (ICC), percent error and linear regression were used …

Blood Count Recovery Following Induction Therapy For Acute Myeloid Leukemia In Children Does Not Predict Survival, Lauren Pommert, Todd M. Cooper, Robert B. Gerbing, Lisa Brodersen, Michael Loken, Alan S. Gamis, Richard Aplenc, Todd A. Alonzo, Edwards Anders Kolb

Manuscripts, Articles, Book Chapters and Other Papers

International Working Group (IWG) and European LeukemiaNet (ELN) response definitions are utilized to evaluate the efficacy of new agents for childhood acute myeloid leukemia (AML) for regulatory purposes. However, these criteria are not consistent with definitions used in pediatric AML trials or with standard pediatric practice to proceed with subsequent therapy cycles prior to IWG/ELN-defined count recovery. We retrospectively analyzed data from the two most recent Phase 3 pediatric AML clinical trials conducted by the Children’s Oncology Group (COG) to assess the incidence, timing, and prognostic significance of count recovery following induction chemotherapy. Of the patients with fewer than 5% …

Surgical Management Of Atrial-Esophageal Fistula As A Complication Of Atrial Fibrillation Ablation., Amber Duda, Kevin Beers, Mohi Mitiek

Manuscripts, Articles, Book Chapters and Other Papers

Atrial-esophageal fistula (AEF) is a rare, but life-threatening complication of ablative treatments for atrial fibrillation. Although the incidence of this complication is low, the mortality is very high. There are many surgical approaches to this disease but we offer a novel technique to reduce the number of incisions used and provides central cannulation. It also allows for repair of both the esophagus and atrium and buttresses these repairs, which have both been shown to decrease morbidity and mortality. The technique has been successful in our three patients and can be considered as an approach to surgical management of AEF.

Ventilation-Induced Lung Injury (Vili) In Neonates: Evidence-Based Concepts And Lung-Protective Strategies., Renjithkumar Kalikkot Thekkeveedu, Ahmed El-Saie, Varsha Prakash, Lakshmi Katakam, Binoy Shivanna

Manuscripts, Articles, Book Chapters and Other Papers

Supportive care with mechanical ventilation continues to be an essential strategy for managing severe neonatal respiratory failure; however, it is well known to cause and accentuate neonatal lung injury. The pathogenesis of ventilator-induced lung injury (VILI) is multifactorial and complex, resulting predominantly from interactions between ventilator-related factors and patient-related factors. Importantly, VILI is a significant risk factor for developing bronchopulmonary dysplasia (BPD), the most common chronic respiratory morbidity of preterm infants that lacks specific therapies, causes life-long morbidities, and imposes psychosocial and economic burdens. Studies of older children and adults suggest that understanding how and why VILI occurs is essential …
