Incidence Of Initial Renal Replacement Therapy Over The Course Of Kidney Disease In Children., Derek K. Ng, Matthew B. Matheson, Bradley A. Warady, Susan R. Mendley, Susan L. Furth, Alvaro Muñoz

Manuscripts, Articles, Book Chapters and Other Papers

The Chronic Kidney Disease in Children Study, a prospective cohort study with data collected from 2003 to 2018, provided the first opportunity to characterize the incidence of renal replacement therapy (RRT) initiation over the life course of pediatric kidney diseases. In the current analysis, parametric generalized gamma models were fitted and extrapolated for RRT overall and by specific treatment modality (dialysis or preemptive kidney transplant). Children were stratified by type of diagnosis: nonglomerular (mostly congenital; n = 650), glomerular-hemolytic uremic syndrome (HUS; n = 49), or glomerular-non-HUS (heterogeneous childhood onset; n = 216). Estimated durations of time to RRT after …

Anticipation, Accompaniment, And A Good Death In Perinatal Care., Bryanna S. Moore, Brian S. Carter, Bryan Beaven, Katie House, Joel House

Manuscripts, Articles, Book Chapters and Other Papers

The ethics of perinatal care, and the experiences of families who receive such care, remains a nascent area of inquiry. It can be hard to see how existing "good death" constructs apply to the experiences of fetal patients and their families. In this paper, we explore two themes raised by a case at our fetal health center: anticipation and accompaniment. In this case, a mother presented to our fetal health center; her unborn son, our fetal patient, was diagnosed with life-threatening hypoplastic left heart syndrome and endocardial fibroelastosis. The parents were told that their son's life expectancy, upon birth, was …

Transanal-Only Swenson-Like Pull-Through For Late Diagnosed Hirschsprung Disease., Rebecca M. Rentea, Devin R. Halleran, Hira Ahmad, Elias Maloof, Richard J. Wood, Marc A. Levitt

Manuscripts, Articles, Book Chapters and Other Papers

Hirschsprung disease (HD) is an obstructive colonic process usually diagnosed in the neonatal period. A small subset of cases are diagnosed late, present with severe constipation without enterocolitis and have low rectosigmoid disease. A transanal-only pull-through is a well-described approach but in the newborn period risks a situation whereby the transition zone is higher than the sigmoid. We present our experience with the unique patient population of older HD patients in whom the transition zone was reliably reachable via a single-stage transanal approach, performed in prone position. Patients between 2 and 6 years of age with a rectal or sigmoid …

Unraveling Complexity About Childhood Obesity And Nutritional Interventions: Modeling Interactions Among Psychological Factors., Keith Feldman, Gisela M B Solymos, Maria Paula De Albuquerque, Nitesh V. Chawla

Manuscripts, Articles, Book Chapters and Other Papers

As the global prevalence of childhood obesity continues to rise, researchers and clinicians have sought to develop more effective and personalized intervention techniques. In doing so, obesity interventions have expanded beyond the traditional context of nutrition to address several facets of a child's life, including their psychological state. While the consideration of psychological features has significantly advanced the view of obesity as a holistic condition, attempts to associate such features with outcomes of treatment have been inconclusive. We posit that such uncertainty may arise from the univariate manner in which features are evaluated, focusing on a particular aspect such as …

An Electronic Medical Records-Based Approach To Identify Idiosyncratic Drug-Induced Liver Injury In Children., Tracy L. Sandritter, Jennifer Goldman, Clayton J Habiger, James F. Daniel, Jennifer Lowry, Ryan T. Fischer

Manuscripts, Articles, Book Chapters and Other Papers

Drug-induced liver injury (DILI) is the leading cause of liver failure in the United States and the most common cause of drug recall. As opposed to the recognized direct toxicity of super-therapeutic acetaminophen or chemotherapeutic agents in children, limited data exists for pediatric populations on the incidence of idiosyncratic DILI (iDILI) that may develop independently of drug dose or duration of administration. To improve the detection of adverse drug reactions at our hospital, we utilized electronic medical records-based automated trigger tools to alert providers of potential iDILI. Clinical criteria concerning for iDILI were defined as serum ALT > 5x or serum …

Pneumothorax: What’S A Pediatric Pulmonologist To Do?, Terrence W. Carver

Manuscripts, Articles, Book Chapters and Other Papers

A pneumothorax is a collection of air in the pleural space commonly associated with respiratory symptoms. Patients may be relatively asymptomatic but may present with life-threatening distress. Confirmation of a clinically suspected pneumothorax is most often by chest x-ray when patients have been stabilized. Pneumothoraces are first categorized as primary, secondary, or iatrogenic and informs the evaluation and treatment plan. However, despite management guidelines in the literature, their applicability for pediatric patients is limited. Understanding of the historical risk factors including the acute clinical course and how radiographs, both chest X-ray and CT chest illuminate which patients are at highest …

MSTO1 encodes a cytosolic mitochondrial fusion protein, misato homolog 1 or MSTO1. While the full genotype-phenotype spectrum remains to be explored, pathogenic variants in MSTO1 have recently been reported in a small number of patients presenting with a phenotype of cerebellar ataxia, congenital muscle involvement with histologic findings ranging from myopathic to dystrophic and pigmentary retinopathy. The proposed underlying pathogenic mechanism of MSTO1-related disease is suggestive of impaired mitochondrial fusion secondary to a loss of function of MSTO1. Disorders of mitochondrial fusion and fission have been shown to also lead to mitochondrial DNA (mtDNA) depletion, linking them to the mtDNA …

The Early "Unnatural" History Following Surgical Repair Of Ventricular Septal Defects., Sathish M. Chikkabyrappa, Justin T. Tretter, Arpan R. Doshi, Sujatha Buddhe, Puneet Bhatla, Achi Ludomirsky

Manuscripts, Articles, Book Chapters and Other Papers

Introduction: Surgical outcomes for simple ventricular septal defects (VSD) have been excellent in the past three decades. For this project, the timing of resolution of left-sided dilation and mitral regurgitation (MR) following VSD repair was assessed.

Methods: Echocardiographic data surrounding surgery of 42 consecutive children who underwent surgical patch repair of a VSD were reviewed. The echocardiograms were reviewed up to a mean of 12 months post-operatively (range 9 - 14 months). Quantitative data indexed to body surface area including left atrial (LA) volume, mitral valve annulus diameter, and left ventricular end-diastolic dimension (LVEDD) was analyzed.

Results: The majority of …

Elevated Glucose Acts Directly On Osteocytes To Increase Sclerostin Expression In Diabetes, Donna M. Pacicca, Tammy Brown, Dara Watkins, Karen Kover, Yun Yan, Matthew Prideaux, Lynda Bonewald

Manuscripts, Articles, Book Chapters and Other Papers

© 2019, The Author(s).

Bone quality in diabetic patients is compromised, leading to weaker bones and increased fracture risk. However, the mechanism by which this occurs in diabetic bone remains to be fully elucidated. We hypothesized that elevated glucose and glucose variation would affect the function of osteocytes, essential regulators of bone homeostasis and quality. To first test this hypothesis, we used the IDG-SW3 osteocyte-like cell line to examine the effects of glucose levels on osteocyte function and viability in vitro. We confirmed our in vitro findings using the in vivo streptozotocin-induced (STZ) diabetic rat model and ex-vivo cultured osteocytes …

Manuscripts, Articles, Book Chapters and Other Papers

Here, we report 17 nearly complete genome sequences of enterovirus D68 (EV-D68) isolated from Kansas City, MO, in 2018. Phylogenetic analysis suggests that these strains belong to subclade B3, similar to the ones that caused the 2016 epidemics in the United States but different from the 2014 outbreak B1 strains.

Pain, Functional Disability, And Their Association In Juvenile Fibromyalgia Compared To Other Pediatric Rheumatic Diseases., Mark Connelly, Jennifer E Weiss, Carra Registry Investigators

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Severe pain and impairments in functioning are commonly reported for youth with juvenile fibromyalgia. The prevalence and impact of pain in other diseases commonly managed in pediatric rheumatology comparatively have been rarely systematically studied. The objective of the current study was to determine the extent to which high levels of pain and functional limitations, and the strength of their association, are unique to youth with juvenile primary fibromyalgia syndrome/JPFS) relative to other pediatric rheumatic diseases.

METHODS: Using data from 7753 patients enrolled in the multinational Childhood Arthritis and Rheumatology Research Alliance (CARRA) Legacy Registry, we compared the levels and …

Background Risk-adjusted adverse event (AE) rates have been used to measure the quality of pediatric and congenital cardiac catheterization laboratories. In other settings, failure to rescue (FTR) has demonstrated utility as a quality metric. Methods and Results A multicenter retrospective cohort study was performed using data from the IMPACT (Improving Adult and Congenital Treatment) Registry between January 2010 and December 2016. A modified FTR metric was developed for pediatric and congenital cardiac catheterization laboratories and then compared with pooled AEs. The associations between patient- and hospital-level factors and outcomes were evaluated using hierarchical logistic regression models. Hospital risk standardized ratios …

Pharmacometabolomics Of Respiratory Phenotypic Response To Dexamethasone In Preterm Infants At Risk For Bronchopulmonary Dysplasia., Tamorah R. Lewis Md Phd, Prabhakar Chalise, Cheri Gauldin, William E. Truog

Manuscripts, Articles, Book Chapters and Other Papers

A prospective cohort study was performed in preterm infants less than 32 weeks gestation at birth who were treated with dexamethasone for developing or established bronchopulmonary dysplasia (BPD). Respiratory phenotype (Respiratory Severity Score (RSS)), serum, and urine metabolomics were assessed before and after treatment. Ten infants provided nine matched serum and nine matched urine samples. There was a significant decrease in RSS with steroid treatment. Serum gluconic acid had the largest median fold change (140 times decreased, P = 0.008). In metabolite set enrichment analysis, in both serum and urine, the urea cycle, ammonia recycling, and malate-aspartate shuttle pathways were …

Germline mutations in SAMD9 and SAMD9L genes cause MIRAGE (myelodysplasia, infection, restriction of growth, adrenal hypoplasia, genital phenotypes, and enteropathy) (OMIM: *610456) and ataxia-pancytopenia (OMIM: *611170) syndromes, respectively, and are associated with chromosome 7 deletions, myelodysplastic syndrome (MDS), and bone marrow failure. In this retrospective series, we report outcomes of allogeneic hematopoietic cell transplantation (HCT) in patients with hematologic disorders associated with SAMD9/SAMD9L mutations. Twelve patients underwent allogeneic HCT for MDS (n = 10), congenital amegakaryocytic thrombocytopenia (n = 1), and dyskeratosis congenita (n = 1). Exome sequencing revealed heterozygous mutations in SAMD9 (n = 6) or SAMD9L (n = …

Sirna Targeting And Treatment Of Gastrointestinal Diseases., Rachel Chevalier

Manuscripts, Articles, Book Chapters and Other Papers

RNA interference via small interfering RNA (siRNA) offers opportunities to precisely target genes that contribute to gastrointestinal (GI) pathologies, such as inflammatory bowel disease, celiac, and esophageal scarring. Delivering the siRNA to the GI tract proves challenging as the harsh environment of the intestines degrades the siRNA before it can reach its target or blocks its entry into its site of action in the cytoplasm. Additionally, the GI tract is large and disease is often localized to a specific site. This review discusses polymer and lipid-based delivery systems for protection and targeting of siRNA therapies to the GI tract to …

Current Practice Patterns In The Diagnosis And Management Of Sleep-Disordered Breathing In Infants., Rachana Kombathula, David G. Ingram Md, Zarmina Ehsan Md

Manuscripts, Articles, Book Chapters and Other Papers

STUDY OBJECTIVES: Currently, there are no universally accepted guidelines for diagnosis and management of sleep-disordered breathing (SDB) in infants. The purpose of this study was to survey pediatric sleep medicine providers regarding their current practice patterns for diagnosis and management of SDB in infants.

METHODS: An anonymous, web-based survey with 71 questions was distributed via the PEDSLEEP and Ped-Lung listserv, which serve as a hub of communication for pediatric sleep and pulmonary medicine providers worldwide.

RESULTS: Fifty-four providers from eight countries completed the survey. Ninety-six percent of providers reported performing sleep studies in infants with 53% performing more than 30 …

Acetaminophen Protein Adducts In Hospitalized Children Receiving Multiple Doses Of Acetaminophen., Sibo Jiang, Valvanera Vozmediano, Susan M. Abdel-Rahman, Stephan Schmidt, Laura P. James

Manuscripts, Articles, Book Chapters and Other Papers

Previous reports have questioned the safety of multiple doses of acetaminophen administered to ill children. Acetaminophen protein adducts (adducts) are a biomarker of acetaminophen-induced liver injury and reflect the oxidative metabolism of acetaminophen, a known mechanism in acetaminophen toxicity. In this prospective observational study, we analyzed adduct concentrations in 1034 blood samples obtained from 181 hospitalized children (1 to 18 years inclusive) who received 2 or more doses of acetaminophen. Linear regression analysis showed that serum adduct concentrations increased as a function of the cumulative acetaminophen dose, which could be attributed, in part, to a long half-life of adducts (2.17 …

Comparison Of Echocardiographic Measurements To Invasive Measurements Of Diastolic Function In Infants With Single Ventricle Physiology: A Report From The Pediatric Heart Network Infant Single Ventricle Trial., Suma P. Goudar, Victor Zak, Andrew M. Atz, Karen Altmann, Steven D. Colan, Christine B. Falkensammer, Mark K. Friedberg, Michele Frommelt, Kevin D. Hill, Daphne T. Hsu, Jami C. Levine, Renee Margossian, Christopher R. Mart, Joshua Sticka, Peter Shrader, Girish S. Shirali, Pediatric Heart Network Investigators

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: While echocardiographic parameters are used to quantify ventricular function in infants with single ventricle physiology, there are few data comparing these to invasive measurements. This study correlates echocardiographic measures of diastolic function with ventricular end-diastolic pressure in infants with single ventricle physiology prior to superior cavopulmonary anastomosis.

METHODS: Data from 173 patients enrolled in the Pediatric Heart Network Infant Single Ventricle enalapril trial were analysed. Those with mixed ventricular types (n = 17) and one outlier (end-diastolic pressure = 32 mmHg) were excluded from the analysis, leaving a total sample size of 155 patients. Echocardiographic measurements were correlated to …

Given that colon cancer is the third most common cancer in incidence and cause of death in the United States, and current treatment modalities are insufficient, there is a need to develop novel agents. Towards this, here we focus on γ-Mangostin, a bioactive compound present in the Mangosteen (Garcinia mangostana) fruit. γ-Mangostin suppressed proliferation and colony formation, and induced cell cycle arrest and apoptosis of colon cancer cell lines. Further, γ-Mangostin inhibited colonosphere formation. Molecular docking and CETSA (Cellular thermal shift assay) binding assays demonstrated that γ-Mangostin interacts with transcription factor TCF4 (T-Cell Factor 4) at the β-catenin …

Introduction: The 2012 Kidney Disease: Improving Global Outcomes (KDIGO) Clinical Practice Guidelines for Glomerulonephritis recommend that patients with membranous nephropathy (MN) at risk for progression receive immunosuppressive therapy (IST), usually after 6 months of observation. A cyclophosphamide (CYC) or calcineurin inhibitor (CNI)-based regimen is recommended as first-line IST. However, the extent to which KDIGO recommendations are adopted in practice remains largely unknown.

Methods: We evaluated prescribing practice among patients with primary MN (diagnosed 2010-2018) enrolled in the Cure Glomerulonephropathy Network (CureGN) cohort study. We also evaluated the availability of testing for phospholipase A2 receptor (PLA2R) in the contemporary era.

Manuscripts, Articles, Book Chapters and Other Papers

PURPOSE: Poor adherence to dietary/behaviour modifications as interventions for hypercholesterolemia in paediatric patients often necessitates the initiation of statin therapy. The aim of this study was to develop a joint population pharmacokinetic model for simvastatin and four metabolites in children and adolescents to investigate sources of variability in simvastatin acid exposure in this patient population, in addition to SLCO1B1 genotype status.

METHODS: Plasma concentrations of simvastatin and its four metabolites, demographic and polymorphism data for OATP1B1 and CYP3A5 were analysed utilising a population pharmacokinetic modelling approach from an existing single oral dose (10 mg < 17 years and 20 mg ≥ 18 years) pharmacokinetic dataset of 32 children and adolescents.

RESULTS: The population PK model included …

Improving Recognition And Reporting Of Adverse Drug Reactions In The Nicu: A Quality Improvement Project., Betsy Cammack, Alexandra Oschman, Tamorah R. Lewis Md Phd

Manuscripts, Articles, Book Chapters and Other Papers

Adverse drug reactions (ADRs) are under-recognized and under-reported in the Neonatal Intensive Care Unit (NICU) population, with up to 95% of all ADRs not reported. Compared with non-elderly adults, pediatric patients are 3 times more likely to experience an ADR, with varying rates from 0.6% to 16.8%. The Children's Mercy NICU has an ADR rate of 0.29% (2015). This high rate presents an opportunity to increase recognition and reporting, and improve characterization of ADRs in the NICU.

Methods: The primary aim of this quality improvement project was for 70% of patients who received specified medications (indomethacin, dexmedetomidine, fentanyl, lorazepam, dexamethasone, …

Burden Of Disease In Pediatric Patients With Hypophosphatasia: Results From The Hpp Impact Patient Survey And The Hpp Outcomes Study Telephone Interview., Eric T. Rush, Scott Moseley, Anna Petryk

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Hypophosphatasia (HPP) is a rare, inherited, metabolic bone disease caused by deficient tissue-non-specific isoenzyme of alkaline phosphatase activity that manifests as a broad range of signs/symptoms, including bone mineralization defects and systemic complications. The burden of disease is poorly characterized, particularly in children. This study aimed to characterize the patient-reported burden of disease among children with HPP using two survey instruments: the HPP Impact Patient Survey (HIPS) and the HPP Outcomes Study Telephone interview (HOST).

METHODS: Between September 2009 and June 2011, pediatric patients (aged younger than 18 years) with HPP were recruited to participate in the study via …

Electromechanical Dyssynchrony And Clinically Silent Ventricular Dysfunction In Young Subjects With Ventricular Pacing For Congenital And Early Acquired Av Block, Daniel Forsha, David G. Gamboa, Niels Risum, Andrea Kropf, Christoph P. Hornik, Piers Barker, Joseph Kisslo, Ronald J. Kanter

Manuscripts, Articles, Book Chapters and Other Papers

Purpose: Single site ventricular pacing can result in electromechanical dyssynchrony and LV dysfunction. A classic pattern by strain echocardiography pattern analysis has been defined that specifically identifies electromechanical dyssynchrony that leads to LV dysfunction in other populations. Our purpose is to evaluate for the presence of the classic pattern and an association with LV dysfunction in asymptomatic young subjects with chronic pacing.

Methods: Inclusion criteria of non-surgical 2nd or 3rd degree AV block, normal cardiac anatomy, chronic ventricular pacing (> 95% of beats) and a quality 4-chamber apical image were met by 24 retrospective and 10 prospectively enrolled subjects. Global …

Manuscripts, Articles, Book Chapters and Other Papers

Introduction: There is limited information on effective disease monitoring for prompt interventions in childhood nephrotic syndrome. We examined the feasibility and effectiveness of a novel text messaging system (SMS) for disease monitoring in a multicenter, prospective study.

Methods: A total of 127 patientsresults, symptoms, and medication adherence were sent to a designated caregiver (n = 116) or adolescent patient (n = 3). Participants responded by texting. Feasibility of SMS was assessed by SMS adoption, retention, and engagement, and concordance between participant-reported results and laboratory/clinician assessments. The number of disease relapses and time-to-remission data captured by SMS were compared …

Comparison Of The Use Of Wireless Capsule Endoscopy With Magnetic Resonance Enterography In Children With Inflammatory Bowel Disease., Nadia Mazen Hijaz, Thomas M. Attard, Jennifer Colombo, Neil J. Mardis, Craig A. Friesen

Manuscripts, Articles, Book Chapters and Other Papers

Background: Magnetic resonance enterography (MRE) and wireless capsule endoscopy (WCE) are equally accepted modalities for noninvasive screening of small bowel involvement (SBI) in children with Crohn's disease (CD) and indeterminate colitis (IC) albeit there is a paucity of data comparing the two and thereby guiding the clinician in selecting the ideal diagnostic approach. Therefore, the goal of this study is to provide additional evidence for capsule endoscopy role in the evaluation of established Crohn's disease exacerbation compared to MRE in relation to Pediatric Crohn's Disease Activity Index (PCDAI), and histological indices.

Aim: To prospectively compare the findings of MRE and …
