Genes Predictive Of Aggressive Infant Acute Lymphoblastic Leukemia, Meghana Bhumireddy

Research Days

Background: Acute Lymphoblastic Leukemia (ALL) is a rapidly progressive cancer in which the bone marrow makes too many immature leukocytes that divide uncontrollably. KMT2A, or MLL, is a methyltransferase found in many types of leukemia, whose rearrangement (KMT2A-r) is present in approximately 2/3 of infants with ALL. KMT2A-r is associated with a very poor prognosis: roughly ⅔ of patients relapse within 1 year of diagnosis, and the relapsed KMT2A-r ALL is resistant to treatment (having nearly 100% morality). We explored gene expression in patient samples from three groups at diagnosis: KMT2A-r patients who relapsed, KMT2A-r patients who did not relapse, …

Drug Metabolizing Enzymes And Transporters May Help Determineeffective Budesonide Dosing In Eoe, Laurie Mccann, Lisa Harvey, Norah Almahbub, Wendy Y. Wang, Erin C. Boone, Janelle R. Noel-Macdonnell Phd, Rachel Chevalier

Research Days

Background: Eosinophilic esophagitis (EoE) is a chronic inflammatory disorder diagnosed in children with painful or difficult swallowing, vomiting, or poor weight gain. Current treatment models adopt a trial-and-error approach in regard EoE treatment, including restrictive elimination diets, proton pump inhibitors, and topical budesonide. This approach can delay effective treatment which increases risk of disease progression and increases medical costs to families for frequent clinic visits and endoscopy.

Objectives/Goal: The objective of this study is to determine the CYP3A5 genotype and expression of patients with eosinophilic esophagitis to discover which patients will respond to standard dosing of topical budesonide treatment (1, …

Rentea, Pablo Aguayo, David Juang, Jason D. Fraser, Charles L. Snyder, Richard J. Hendrickson, Tolulope A. Oyetunji, Shawn D. St.Peter

Research Days

Background: Primary spontaneous pneumothorax (PSP) affects 3.4 per 100,000 children in the United States. Regardless of the initial management, additional procedures, and prolonged hospital length of stay (LOS) may occur. There is currently no consensus in the pediatric surgical community on the optimal management of these patients, which has resulted in marked variability in management. The Midwest Pediatric Surgery Consortium (MWPSC), of which our site is a participant, suggested a management algorithm to include simple aspiration upon presentation, and if this fails, VATS should be considered.

Objectives/Goal: The purpose of this study was to evaluate the outcomes of instituting a …

Research Days

Background: The Arizona-Texas-Oklahoma-Memphis-Arkansas Consortium (ATOMAC) practice management guideline (PMG) was created to standardize management of blunt liver or spleen injury (BLSI) across pediatric trauma centers. Evaluations of institutional outcomes after its adoption remain scarce. We describe our outcomes since PMG adoption at our institution.

Objectives/Goal: The purpose of this study was to assess patient outcomes and resource utilization after implementation of this protocol. We hypothesized there is no difference in length of stay (LOS) or complications regardless of grade of isolated injuries to the liver or spleen. In addition, there is limited guidance on the management of concurrent injuries to …

A Novel Approach For Laparoscopic Direct Inguinal Hernia Repair In Children, Shai Stewart Md, Charlene Dekonenko, Nelimar Cruz-Centeno, Derek Marlor, Jason D. Fraser

Research Days

Background: Inguinal hernia repair is one of the most common operations performed by pediatric surgeons, and the frequency of laparoscopy for repair is increasing. The vast majority of these are indirect hernias and therefore how to best repair a direct defect when seen during laparoscopy is still unknown. Simple high ligation of the hernia sac (as is done in an indirect hernia) does not repair the inguinal floor weakness/defect seen in a direct hernia.

Objectives/Goal: We therefore present a case of laparoscopic bilateral indirect and direct inguinal hernia repair, commonly known as pantaloon hernia, repaired without mesh and utilizing the …

Antibiotic Monotherapy Vs Dual-Drug Therapy In Perforated Appendicitis: Single Center Retrospective Review, Shai Stewart Md, Nelimar Cruz-Centeno, Derek Marlor, Dae H. Kim, Shawn D. St Peter, Tolulope A. Oyetunji Md Mph

Research Days

Background: The optimal antibiotic regimen in perforated appendicitis to reduce intraabdominal abscess (IAA) formation has not yet been agreed upon in the pediatric surgery community. We aimed to evaluate the outcomes of patients with perforated appendicitis when intravenous antibiotic monotherapy with Piperacillin-Tazobactam (PT) versus dual-drug therapy with Ceftriaxone and Metronidazole (CM) are administered. We hypothesized there is no difference in the rate of IAA formation with antibiotic monotherapy, as opposed to our once-daily dosed, institutional standard dual-drug therapy.

Objectives/Goal: The goal was to determine if our current management protocols for acute appendicitis were delivering the best possible results for our …

A Comparison Of Large Tbsa Scald Versus Flame Burns In Young Children, Ashley Daniel

Research Days

Background: It is generally accepted that of children with the same total body surface area of burns, those with flame burns seem to have longer lengths of stay and more complications than those with scald burns. Anecdotally we have seen the opposite to be true. Among a consortium of five US pediatric burn centers participating in the Pediatric Injury Quality Improvement Collaborative (PIQIC), young children with scald burns seem to experience disproportionately more frequent and severe complications compared to their older counterparts and compared to patients of a similar age with flame burns.

Objectives/Goal: In this multi-institutional study, we compared …

Relationship Between Rurality And Access To Care For Families Of Hospitalized Children, Zoetta L. Mcloughlin Md

Research Days

Background: At Children’s Mercy Hospital, greater than 1 in 5 hospitalized children are from rural areas. Rural families often travel long distances for hospitalization at free-standing children’s hospitals, a median of 70 miles according to recent work. Rural families are more likely than non-rural families to experience financial insecurity, and these baseline hardships may be intensified during hospitalization due to out-of-pocket costs, lost work, inability to meet family needs, and removal from social support. However, little is known about the differences in healthcare access and resulting burdens between rural and non-rural families.

Objectives/Goal: To describe differences in demographics, health care …

Rural And Urban Caregiver Experiences Of Financial Strain And Food Insecurity During Pediatric Hospitalizations, Rachel E. Granberg

Research Days

Background: Stress is common among caregivers of hospitalized children. In addition to stress related to their child’s illness, caregivers experience stress related to financial strain and food insecurity during their child’s hospitalization. The burden of financial strain and food insecurity related to pediatric hospitalizations may vary between rural and urban populations.

Objectives/Goal: To identify financial strain and food insecurity experienced by caregivers of hospitalized children and to describe differences between rural and urban populations.

Methods/Design: A prospective cross-sectional survey enrolled a random sample of caregivers of hospitalized children between 8/31/2021 and 12/2/2022 at a single children’s hospital. Demographic information was …

Female Authorship Concordance In Academic Pediatrics, Roxana Guggenmous, Jessica L. Bettenhausen, Jessica L. Markham

Research Days

Background: Gender disparities are well described in medicine and academia. Despite a catalyzed movement towards gender equity, female physician-scientists remain at risk for experiencing biases in hiring practices, compensation, promotion, appointment to leadership positions, and achievement of extramural funding through the National Institutes of Health. In pediatrics, the female workforce has grown consistently over time, with female physicians comprising 72.3% of the workforce as of 2021, yet prior work suggests that this growth is not fully reflected in academic publications. Achieving gender parity in academic publication may help reduce gender-based disparities impacting career advancement. Therefore, we sought to describe the …

Research Days

Background: Adverse childhood experiences (ACEs) impact a majority of individuals, with approximately two-thirds of adults having experienced 1 or more ACE.1 The health consequences of ACEs are significant, including cardiovascular disease, cancer, autoimmune diseases, and mental illnesses.1 These health impacts can even start as early as childhood, leading to an increased risk of learning and behavioral concerns.2,3 Recent evidence has also identified the impact that parental ACEs may have on parenting and child development,4,5,6 which in turn may lead to an intergenerational transmission of ACEs.4,7 As a nurturing caregiver relationship is key for buffering adversity,2,8 it is imperative to address …

The Effect Of Scenario-Based Learning On 8th Grade Students’ Perceptions Of Scientists, Fatma Şaşmaz Ören, Ayşegül Karapinar, Kübranur Sari, Tuğba Demi̇rer

Journal of Educational Research and Practice

The aim of our study was to investigate the effect of scenario-based learning on eighth-grade students’ perceptions of scientists. We used a semiexperimental design to conduct our research with 36 students from the eighth grade, who were divided into experimental and control groups. We collected the data through a “Draw-a-Scientist Test,” an opinion form, and semistructured interviews. According to the findings we obtained from the drawing test, students have stereotypical perceptions of the scientists’ working environment (indoor/laboratory). But the results showed that scenario-based teaching affects eighth-grade students’ perceptions of scientists and moves them forward on two points: (1) the physical …

Increasing Utilization Of Gestational Age Based Table For Initial Intubation In A Level Iv Neonatal Intensive Care Unit, Maribel Martinez, Dianne Lee, Christopher R. Nitkin

Research Days

Problem Statement/Question: Most providers in our unit are not using the NRP recommended method to determine the initial ETT insertion depth in neonates.

Background/Project Intent (Aim Statement): Endotracheal tube (ETT) depth in neonates is of critical importance due to significant adverse events when malpositioned. While randomized trials comparing different methods have not shown superiority of any particular method, the weight-based method (weight (kg) +6) has been found to be highly inaccurate in extremely low birth weight neonates. Furthermore, the Neonatal Resuscitation Program (NRP) recommends using gestational age (GA)-based table (Kempley ST, et al, Resuscitation 2008) or nasal-tragal length for initial …

Improving Frequency Of Peer Review Of Abnormal Genital Exam Findings In Patients Undergoing Sexual Abuse Evaluation, Lyndsey Hultman, Julia G. Harris, Terra N. Frazier, Jennifer B. Hansen

Research Days

Problem Statement/Question: Child Advocacy Centers (CACs) coordinate child abuse MDTs, and 2023 CAC accreditation standards require that “all medical professionals providing services to CAC clients must demonstrate that 100% of all findings deemed abnormal or “diagnostic” of trauma from sexual abuse have undergone expert review by an advanced medical consultant.” Scheduled Case Review occurs among Children’s Mercy child abuse pediatricians (CAPs), but current practice is to review cases only upon CAP request.

Background/Project Intent (Aim Statement): Appropriate interpretation of sexual abuse exam findings is crucial for accurate diagnosis and provision of medical information to multidisciplinary child protection teams (MDTs). Medical …

Learning To Teach Prospective Elementary Teachers: A Narrative Inquiry Of A Newer Mathematics Content Instructor, Kelsey Quaisley

Department of Teaching, Learning, and Teacher Education: Theses and Other Student Research

Learning to teach mathematics content courses designed for prospective elementary teachers (PTs) is challenging. Mathematics content instructors must be prepared to not only teach mathematics content, but engage PTs in understanding children’s mathematical thinking strategies, learning trajectories, and misconceptions (Carpenter et al., 1996; Carpenter & Moser, 1982; I et al., 2020). When considering how instructors might best be prepared and supported, however, one must recognize that there is significant variation in the backgrounds and expertise of mathematics content instructors (Masingila et al., 2012; Yow et al., 2016) and little is known about the preparation, knowledge, and experiences of mathematics content …
