A Systematic Review And Meta-Analysis Of Non-Suicidal Self-Injury Among Incarcerated Juveniles, Chikira H. Barker, Justin Gibson, Rose Tusa, Charlotte Pearson, Aaron Mack, Sydney Sukhdeo, Rahn K. Bailey

School of Medicine Faculty Publications

Non-suicidal self-injury (NSSI) most commonly occurs during adolescence, and it represents one of the highest risk factors for future suicidal behaviors. Understanding the prevalence, risk factors, and effective treatments in high-risk groups, such as adolescents who are criminally incarcerated, is of substantial importance. A systematic review was conducted on articles related to NSSI in incarcerated adolescents. The results of the meta-analysis found that the pooled estimated prevalence of NSSI in this population is 28% (95% CI: 0.21–0.36). Studies varied in their methods of measuring NSSI, with some relying on medical record reviews, unstandardized assessments, or standardized assessments. Several demographic, social, …

Association Of Right Ventricular Dysfunction With Risk Of Neurodevelopmental Impairment In Infants With Pulmonary Hypertension, Rossana Romero Orozco, Tazuddin Mohammed, Kerri Carter, Shaaron Brown, Stephen Miller, Roy Sabo, Meredith Campbell Joseph, Uyen Truong, Megha Nair, Victoria Anderson, Jie Xu, Judith Voynow, Karen Hendricks-Muñoz

SKMC Student Presentations and Publications

(1) Background: Pulmonary hypertension (PH) increases pulmonary vascular resistance and right ventricular (RV) afterload. Assessment of RV systolic function in PH using RV fractional area change (RV FAC) as a marker directly correlates with mortality and the need for extracorporeal membrane oxygenation (ECMO). However, few studies have assessed neurodevelopmental outcomes. We hypothesize that cardiac RV systolic dysfunction with lower RV FAC is associated with worse neurodevelopmental impairment (NI).

(2) Methods: Retrospective study of 42 subjects with PH to evaluate neurodevelopmental outcomes in the first two years of life based on (i) subjective assessment of RV systolic function and (ii) RV …

Microglia In Post-Mortem Hippocampal Brain Tissue Of Male And Female Neonates After Hie, Kassandra M. Pulido, Angela N. Viaene, Amelia J. Eisch, Danielle G. Barber

Research Colloquium

Background: Hypoxic-ischemic encephalopathy (HIE) is the second-leading cause of neonatal morbidity and mortality worldwide. There are sex differences in the pathophysiology of HIE, particularly in microglia, which are critical in the immune response. Prior work highlights microglial aggregation in the hippocampus of human infants as a marker for HIE, but it is unknown whether this differs by sex.

Aim: We compare the microglial response in post-mortem hippocampal tissue from male and female neonates diagnosed with HIE vs. Controls who expired from other causes.

Methods: Using a retrospective cohort design, we reviewed medical records of neonates with hippocampal tissue in the …

Can We Predict Dominant Compensatory Curves In Congenital Scoliosis?, Myung-Jin Cha, William Elnemer, Paul D. Sponseller

Research Colloquium

Background: A complication in the natural evolution of congenital scoliosis is the development of a compensatory curve. Congenital curves are often focal and rigid, causing patients to develop a compensatory curve cranial and/or caudal to the congenital anomaly to achieve coronal balance. Therefore, surgeons are faced with the difficult choice of waiting for the patient to reach an appropriate age for surgery or correcting the congenital curve before a compensatory curve develops.

Methods: By searching the Pediatric Spine Study Group database, we identified 307 pediatric patients (age <18) with congenital scoliosis who had preoperative radiographs taken during at least 2 years of natural growth (without bracing or surgery). Of these patients, 17 (5.5%) had a dominant compensatory curve, and 290 had no compensatory curve or one that was smaller than the congenital curve. Of those 290 patients, we randomly selected 100 to serve as a control group, referred to as the nondominant curve cohort. We extracted data on the type of congenital anomaly and its vertebral level, as well as the Cobb angles of the congenital and compensatory curves at initial and latest follow-up. We compared vertebral level and type of congenital anomaly via chi-squared test between the dominant and nondominant curve group.

Results: The congenital anomaly was located at L4 or more caudal in 18% …

Manuscripts, Articles, Book Chapters and Other Papers

OBJECTIVE: Wearable monitors are increasingly used to assess sleep. However, validity is unknown for certain monitors and populations. We tested the Garmin Vivofit 4 in a pediatric clinical sample.

METHODS: Participants (n = 25) wore the monitor on their nondominant wrist during an overnight polysomnogram. Garmin and polysomnography were compared using 95% equivalence testing, mean absolute error, and Bland-Altman analysis.

RESULTS: On average (mean ± SD), the Garmin predicted later sleep onset (by 0.84 ± 1.60 hours) and earlier sleep offset (by 0.34 ± 0.70 hours) than polysomnography. The resulting difference for total sleep time was -0.55 ± 1.21 hours. …

World Allergy Organization (Wao) Diagnosis And Rationale For Action Against Cow's Milk Allergy (Dracma) Guideline Update – Xi – Milk Supplement/Replacement Formulas For Infants And Toddlers With Cma – Systematic Review, Antonio Bognanni, Ramon Firmino, Stefania Arasi, Derek Chu, Alexandro Chu, Siw Waffenschmidt, Arnav Agarwal, Piotr Dziechciarz, Andrea Horvath, Rose Kamenwa

Paediatrics and Child Health, East Africa

Background: Cow's milk allergy (CMA) is the most complex and common food allergy in infants. Elimination of cow's milk from the diet and replacement with a specialized formula for infants with cow's milk allergy who cannot be breastfed is an established approach to minimize the risk of severe allergic reactions while avoiding nutritional deficiencies. Given the availability of multiple options, such as extensively hydrolyzed cow's milk-based formula (eHF-CM), aminoacid formula (AAF), hydrolyzed rice formula (HRF), and soy formula (SF), there is some uncertainty regarding which formula might represent the most suitable choice with respect to health outcomes. The addition of …

Medical Education Faculty Publications

Objectives: Proper emergency department (ED) utilization is a hallmark of population health. Emergency department overcrowding due to nonurgent visits causes increased stress to healthcare staff, higher costs, and longer wait times for more urgent cases. This study sought to better understand post pandemic reasons caregivers have when bringing in their children for nonurgent visits and devise effective interventions to improve caregiver choice for non-ED care for nonurgent conditions.

Methods: Surveys were conducted at an urban pediatric hospital for Emergency Severity Index (ESI) level 3 to 5 visits. A total of 602 surveys were completed with 8 being excluded from analysis. …

Competency-Based Medical Education And The Education Continuum: Establishing A Framework For Lifelong Learning, Ann E. Burke, Daniel J. Sklansky, Hilary M. Haftel, Andrew Mitchell, Keith J. Mann

Pediatrics Faculty Publications

Competency Based Medical Education (CBME) is built on the concept that the competencies of learners, both graduates and practicing physicians, should ensure they are ready to meet the ever-changing healthcare needs of patients.1, 2, 3 Education outcomes in a CBME system are defined based on the needs of patients, and in healthy CBME systems, there is a paradigm shift from a focus on process and teachers to outcomes and learners.2,4 CBME should occur across the continuum of one's career, from undergraduate medical education through retirement. Furthermore, learners must be accustomed to driving their own educational processes.4,5 This learner-centered perspective requires …

Minimally Invasive Repair Of Pectus Excavatum Without Stabilizers Does Not Result In Increased Bar Displacement Or Other Post-Operative Complications, Meredith Elman, Seth Saylors, Ismael Elhalaby, Pablo Aguayo

Presentations

Introduction/Purpose Since the Nuss procedure was first performed in the 1990s, surgeons have adopted various modifications and techniques that vary by practice to optimize patient outcomes and minimize complications following pectus excavatum repair. Bar dislocation is a particularly dreaded complication, and as such, many Nuss bars are secured using unilateral or bilateral stabilizers. However, additional foreign body use can be associated with increased morbidity such as infection at stabilizer sites (~3% incidence), and pain attributed to stabilizer presence. Beginning in 2020, individuals in our practice did not place stabilizers in patients undergoing minimally invasive repair of pectus excavatum (MIRPE), and …

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) occurs in 70% of cases and 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). This KMT2A-r generates a driver fusion oncogene which leads to epigenetic dysregulation of target gene transcription. Infant ALL’s cell of origin is thought to be a very early hematopoietic precursor, with transcriptomic studies of iALL blasts showing similarities to …

Posters

Background: There are approximately 11.4 million undocumented immigrants (UI) in the United States. Immigration status (IS) is a unique social determinant of health that directly and indirectly impacts health and healthcare access. There are gaps in our understanding about how IS impacts health, particularly because it is not frequently discussed in the healthcare setting. This study expands our understanding of immigrant caregiver perceptions about discussing IS in the healthcare setting and provides insight into specific needs that we may not be currently addressing. Methods: Setting: ED or Spanish-speaking majority pediatric clinic at Children's Mercy Inclusion criteria: Caregivers who are 18+, …

Episodes Of Acute Methotrexate-Related Neurotoxicity Linked To Compromised Long-Term Neurocognitive Function, Rachel D Harris, Olga A Taylor, Kimberly P Raghubar, Mariana Matheus Gonzalez, Mark Zobeck, M Monica Gramatges, Karen R Rabin, Michael E Scheurer, Austin L Brown

Faculty, Staff and Students Publications

Methotrexate is a critical component of curative chemotherapy for pediatric acute lymphoblastic leukemia (ALL), but is associated with neurotoxicity. Information on long-term outcomes following an acute neurotoxic event is limited. Therefore, this report compares neurocognitive performance more than 12 months post diagnosis (mean = 4 years) between ALL patients with (n = 25) and without (n = 146) a history of acute neurotoxicity. Compared to children with no documented on-treatment neurotoxic event, children who experienced a neurotoxic event during treatment exhibited poorer performance on measures of fine motor function (p = .02) and attention (p = .02). Children with ALL …

BACKGROUND: Dupilumab is a monoclonal antibody that targets the interleukin (IL)-4 receptor alpha subunit, thus blocking the effects of IL-4 and IL-13, and has shown efficacy in treating various conditions including asthma, atopic dermatitis, eosinophilic esophagitis, and others. Because of its immune modulatory effects, clinical trials that studied dupilumab did not allow patients to receive live vaccines during the clinical trials because of an abundance of caution, and thus package inserts recommend that patients who are being treated with dupilumab should avoid live vaccines. Because dupilumab is now approved for use in patients from 6 months of age for the …

Tuberculosis Prevention: Current Strategies And Future Directions, Anca Vasiliu, Leonardo Martinez, Rishi K Gupta, Yohhei Hamada, Tara Ness, Alexander Kay, Maryline Bonnet, Martina Sester, Stefan H E Kaufmann, Christoph Lange, Anna M Mandalakas

Faculty, Staff and Students Publications

BACKGROUND: An estimated one fourth of the world's population is infected with Mycobacterium tuberculosis, and 5-10% of those infected develop tuberculosis in their lifetime. Preventing tuberculosis is one of the most underutilized but essential components of curtailing the tuberculosis epidemic. Moreover, current evidence illustrates that tuberculosis manifestations occur along a dynamic spectrum from infection to disease rather than a binary state as historically conceptualized. Elucidating determinants of transition between these states is crucial to decreasing the tuberculosis burden and reaching the END-TB Strategy goals as defined by the WHO. Vaccination, detection of infection, and provision of preventive treatment are key …

Distinct Basal Forebrain-Originated Neural Circuits Promote Homoeostatic Feeding And Suppress Hedonic Feeding In Male Mice, Hailan Liu, Jonathan C Bean, Yongxiang Li, Meng Yu, Olivia Z Ginnard, Kristine M Conde, Mengjie Wang, Xing Fang, Hesong Liu, Longlong Tu, Na Yin, Junying Han, Yongjie Yang, Qingchun Tong, Benjamin R Arenkiel, Chunmei Wang, Yang He, Yong Xu

Faculty, Staff and Students Publications

Feeding behaviour is influenced by two primary factors: homoeostatic needs driven by hunger and hedonic desires for pleasure even in the absence of hunger. While efficient homoeostatic feeding is vital for survival, excessive hedonic feeding can lead to adverse consequences such as obesity and metabolic dysregulations. However, the neurobiological mechanisms that orchestrate homoeostatic versus hedonic food consumption remain largely unknown. Here we show that GABAergic proenkephalin (Penk) neurons in the diagonal band of Broca (DBB) of male mice respond to food presentation. We further demonstrate that a subset of DBBPenk neurons that project to the paraventricular nucleus of the hypothalamus …
