What are the spatial and temporal scales of brainwide neuronal activity? We used swept, confocally-aligned planar excitation (SCAPE) microscopy to image all cells in a large volume of the brain of adult Drosophila with high spatiotemporal resolution while flies engaged in a variety of spontaneous behaviors. This revealed neural representations of behavior on multiple spatial and temporal scales. The activity of most neurons correlated (or anticorrelated) with running and flailing over timescales that ranged from seconds to a minute. Grooming elicited a weaker global response. Significant residual activity not directly correlated with behavior was high dimensional and reflected the activity …

Early Exposure To Added Sugars Via Infant Formula May Explain High Intakes Of Added Sugars During Complementary Feeding Beyond Maternal Modeling., Adrianne K. Griebel-Thompson, Tera L. Fazzino, Emily Cramer, Rocco A. Paluch, Katherine S. Morris, Kai Ling Kong

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Research has shown that early exposure to added sugars from table food is related to increased intake of added sugars in later childhood. The earliest window of exposure to added sugars may be in infancy via infant formula. However, beyond the well-established factors of maternal lifestyle and modeling, there is a lack of research examining how exposure to added sugars from infant formula influences infant/toddler added sugar intakes from table foods and sugar sweetened beverages (SSB).

OBJECTIVE: While accounting factors previously associated with infant/toddler added sugar intakes and maternal SSB consumption (proximal measure of maternal modeling), this study aims …

Introduction: To ensure the quality of clinical trial safety data, universal data standards are required. In 2019 the International Neonatal Consortium (INC) published a neonatal adverse event severity scale (NAESS) to standardize the reporting of adverse event (AE) severity. In this study the reliability of AE severity grading with INC NAESS was prospectively assessed in a real-world setting. Methods: Severity of AEs was assessed by two independent observers at each of four centers across the world. In each center two series of 30 neonatal adverse events were assessed by both observers: in a first phase with a generic (Common Terminology …

Xanthine Oxidase Levels And Immune Dysregulation Are Independently Associated With Anemia In Plasmodium Falciparum Malaria, Marilyn Vasquez, Margaux Sica, Ruth Namazzi, Robert Opoka, Julian Sherman, Dibyadyuti Datta, Miquel Duran Frigola, John Ssenkusu, Chandy John, Andrea Conroy

Paediatrics and Child Health, East Africa

Severe anemia is an important contributor to mortality in children with severe malaria. Anemia in malaria is a multi-factorial complication, since dyserythropoiesis, hemolysis and phagocytic clearance of uninfected red blood cells (RBCs) can contribute to this syndrome. High levels of oxidative stress and immune dysregulation have been proposed to contribute to severe malarial anemia, facilitating the clearance of uninfected RBCs. In a cohort of 552 Ugandan children with severe malaria, we measured the levels of xanthine oxidase (XO), an oxidative enzyme that is elevated in the plasma of malaria patients. The levels of XO in children with severe anemia were …

For decades, there has been increasing concern about the potential developmental neurotoxicity (DNT) associated with chemicals. Regulatory agencies have historically utilized standardized in vivo testing to evaluate DNT. Owing to considerations including higher-throughput screening for DNT, reduction in animal use, and potential cost efficiencies, the development of alternative new approach methods (NAMs) occurred; specifically, the advent of the DNT in vitro test battery (DNT IVB). SciPinion convened an expert panel to address specific questions related to the interpretation of in vitro DNT test data. The consensus of the expert panel was that the DNT IVB might be used during initial …

Renin As A Biomarker Of Acute Kidney Injury And Mortality In Children With Severe Malaria Or Sickle Cell Disease, Daniel Adan, Anthony Batte, Ruth Namazzi, Ivan Mufumba, Caroline Kazinga, Kagan Mellencamp, Caitlin Bond, Robert Opoka, Chandy John, Andrea Conroy

Paediatrics and Child Health, East Africa

Background: Globally, a very high percentage of acute kidney injury (AKI) occurs in low- and middle-income countries (LMICs) where late recognition contributes to increased mortality. There are challenges with using existing biomarkers of AKI in LMICs. Emerging evidence suggests renin may serve as a biomarker of kidney injury that can overcome limitations in creatinine-based diagnostics.

Methods: Two study populations in Uganda were assessed. Cohort #1 was a two-site, prospective cohort study enrolling 600 children with severe malaria (SM). Cohort #2 was a prospective cohort study enrolling 185 children with sickle cell disease (SCD) hospitalized with a vaso-occlusive crisis. Plasma or …

Paediatrics and Child Health, East Africa

Seizures are common in neonates, but there is substantial management variability. The Neonatal Task Force of the International League Against Epilepsy (ILAE) developed evidence-based recommendations about antiseizure medication (ASM) management in neonates in accordance with ILAE standards. Six priority questions were formulated, a systematic literature review and meta-analysis were performed, and results were reported following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) 2020 standards. Bias was evaluated using the Cochrane tool and risk of Bias in non-randomised studies - of interventions (ROBINS-I), and quality of evidence was evaluated using grading of recommendations, assessment, development and evaluation (GRADE). …

METHODS: Electronic health records for 2247 GA4K study participants were used to evaluate the distribution of individuals by demographics (race, ethnicity, and payor type) and location (residential address). Addresses were geocoded to produce point density and 3-digit zip code maps showing local and regional enrollment patterns. Health system reports and census data were used to compare participant characteristics with reference populations at different …

Parental Diabetes Distress Is A Stronger Predictor Of Child Hba1c Than Diabetes Device Use In School-Age Children With Type 1 Diabetes., Susana R. Patton, Nicole Kahhan, Jessica S. Pierce, Matthew Benson, Larry A. Fox, Mark A. Clements

Manuscripts, Articles, Book Chapters and Other Papers

INTRODUCTION: Diabetes distress (DD) describes the unrelenting emotional and behavioral challenges of living with, and caring for someone living with, type 1 diabetes (T1D). We investigated associations between parent-reported and child-reported DD, T1D device use, and child glycated hemoglobin (HbA1c) in 157 families of school-age children.

RESEARCH DESIGN AND METHODS: Parents completed the Parent Problem Areas in Diabetes-Child (PPAID-C) and children completed the Problem Areas in Diabetes-Child (PAID-C) to assess for DD levels. Parents also completed a demographic form where they reported current insulin pump or continuous glucose monitor (CGM) use (ie, user/non-user). We measured child HbA1c using a valid …

Exploring Bidirectionality In Us Pediatric Global Health Programs, Anik Patel, Pauline Kamau, Ashley Combs, Megan Mchenry

Posters

Introduction: Over the last two decades, GH programs have offered experiences at partner sites through established global health partnerships (GHPs). Historically, GHPs have been one-directional, favoring partners from resource-rich settings. These partnerships are now being reevaluated through the lens of equity and decolonization. We seek to understand how US pediatric GH faculty define the concept of “bidirectionality”, assess perspectives on their institution’s practice of bidirectional activities, and explore perceived benefits and challenges to prioritizing bidirectionality within their own GHPs. Methods: This is a cross-sectional qualitative survey study on bidirectionality of 206 AAMC-accredited US pediatric residency programs. 24 survey responses from …

Acute lymphoblastic leukemia in infants (iALL) is a high-risk subtype of childhood leukemia, with poor survival outcomes despite intensive therapies. Rearrangement of KMT2A (KMT2A-r) on chromosome 11q23 is the most frequent cytogenetic abnormality in iALL, occurring in 70% of cases. KMT2A-r is associated with chemotherapy resistance, early relapse, and rapid leukemic progression, all of which contribute to poor survival outcomes. The most common KMT2A-r in iALL is KMT2A::AFF1 (MLL::AF4), derived from t(4;11)(q21;23) and arises in utero as shown in multiple clinical studies. Infant ALL’s cell of origin is thought to be a very early hematopoietic precursor, with transcriptomic studies of …

Background Bovine Pericardium (BP), with numerous and improving preparation techniques, has been used extensively for over 50 years in repair of simple and complex congenital heart defects. It has several advantages over other surgical materials. However, there is a paucity of data in the pediatric population regarding complications associated with BP. Herein, we report two rare complications noted with BP use. Case Description Case 1. A 14-month-old male, with trisomy 21 and complete Atrioventricular canal defect, repaired using BP. A routine surveillance echocardiogram showed a mass attached to the atrial septum and atrial aspect of the left atrioventricular valve (Figure …

“It's So Expensive And Isn’T Any Better! Or Is It?” A Comparative Analysis Of Price Per Ecmo Hour, Intracranial Hemorrhage, And Survival Rates In Neonates On Bivalirudin Vs. Heparin, Johanna I. Orrick, Jessie Charbonneau, Kari L. Davidson, Alexandra Oschman, John M. Daniel Iv

Posters

Background: Heparin has been the anticoagulant of choice for Neonatal ECMO for the past thirty years. It has the benefit of being well studied and having a low production cost. As bivalirudin is a newer anticoagulant, it has not been as widely studied and has a higher production cost, many centers are concerned about changing to a newer, more expensive agent. Bivalirudin has been studied from both an efficacy and cost perspective in adult patients (Sun et al 2021) and pediatric VAD populations (Burnstein et al 2023). While some safety and efficacy data exist for neonates, there are few if …

Screening Utility And Acceptability Of The Kiswahili-Pgals (Paediatric Gait, Arms, Legs, Spine) At A Tertiary Referral Hospital In Kenya-A Diagnostic Accuracy Study, Jacqueline Kawishe, Anthony Ngugi, Stanley Luchters, Helen Foster, Angela Migowa

Paediatrics and Child Health, East Africa

Background:Paediatric rheumatic diseases cause considerable disease burden to children and their families (Moorthy LN, Peterson MGE, Hassett AL, et al, Pediatric Rheumatology 8:20, 2010). Delayed diagnosis is a signifcant determinant of severity and mortality attributed to these conditions (Foster HE, Eltringham MS, Kay LJ, et al, Arthritis Care Res 57(6):921-7, 2007). pGALS is a simple clinical tool used to assess joints and identify musculoskeletal (MSK) conditions in school-going children to enable early referral to paediatric rheumatologists.

Objectives: This study aimed to translate and determine the diagnostic accuracy and acceptability of a Kiswahili version of the pGALS screening tool among …

Rare Case Of Pediatric Post-Transplant Lymphoproliferative Disorder Presenting With Pleural Masses Complicated By Pleural Effusions, Erini Nessim Kostandy, David Wan, Essam Imseis

Faculty, Staff and Student Publications

Post-transplant lymphoproliferative disorder is a complication in organ transplant recipients characterized by uncontrolled proliferation of B-lymphocytes, occurring in 6% of pediatric patients, with risk factors including primary Epstein-Barr virus infection, intensity of immunosuppression, and cytomegalovirus infection. The clinical symptoms are often nonspecific, and it is associated with a high mortality rate if left untreated. We describe a rare case of post-transplant lymphoproliferative disorder who presented with pleural-based masses resulting in pleural effusions.
