Multi-Omic Analysis Of Kmt2a-Rearranged Pediatric Acute Myeloid Leukemia Reveals Novel Pathways Of Interest, Trenton Edwards, Irina Pushel, Thomas Gremminger, Lisa Lansdon, Byunggil Yoo, Michaella Rekowski, Michael Washburn, Midhat Farooqi

Research Days

Objectives/Goals

Acute Myeloid Leukemia (AML) is the second most common leukemia among pediatric populations. Approximately 15% of pediatric AML cases have KMT2A gene rearrangements (KMT2A-r), which carry a worse prognosis. Our goal is to better characterize the biologic landscape of KMT2A-r pediatric AML. We hypothesize that a multi-omic approach will reveal mechanisms underlying the aggressive nature of KMT2A-r AML.

Methods/Study Population

This study makes use of deidentified peripheral blood and/or bone marrow samples banked in the Children’s Mercy Tumor Bank Biorepository. For this study, we used samples at diagnosis and remission from four KMT2A-r pediatric AML …

The Impact Of Race-Corrected Spirometry Results On Eligibility Into An Asthma Clinical Trial, Carina H. Perdew, Bridgette L. Jones, Wumi V. Akinjole

Research Days

BACKGROUND: Spirometry is a widely used pulmonary function test that assesses lung function by examining airflow and capacity. Spirometry measurements assist in the diagnosis, severity classification, and management of asthma, and can affect one’s eligibility into various events (e.g., clinical trials, high-risk jobs, sports). Reference equations are used to establish predicted values to account for biological variables such as age, sex, and height; however past clinical guidelines recommended utilizing race-correction. The incorporation of race may negatively impact people of color due to misrepresentation of one's lung function, consequently impacting future medical management. OBJECTIVES: To characterize differences in spirometry values across …

Delaying Infant Inguinal Hernia Repair Does Not Increase Incarceration Rate, Seth Saylors, Cory Nonnemacher, Charles Snyder, Pablo Aguayo, Richard Hendrickson, Bhargava Mullapudi, Irene Lim-Beutel, Rebecca Rentea, Shawn St. Peter, David Juang, Tolulope Oyetunji

Research Days

Introduction: Inguinal hernia repair is one of the most common pediatric surgical procedures performed with an estimated incidence of 1-5% in children. Patients can present with or without symptoms, with symptomatic hernias (incarcerated or strangulated) that may require emergent or urgent operative intervention. During the Covid-19 pandemic, restrictions, and shutdowns of elective surgeries at our institution resulted in delaying elective inguinal hernia repair unless presenting with more emergent symptoms, with no apparent increase in complication. In our institution, this practice was continued even after COVID restrictions were lifted, with elective repairs delayed until patients were older before completing elective inguinal …

Research Days

Background

Social determinants of health (SDOH) create barriers to seeking care regularly, especially for patients with chronic disease. Patients with moderate-severe hemophilia A and B (factor 8 and 9 deficiencies respectively) have a life-long higher risk of bleeding and require chronic therapies. Specialized care is offered through hemophilia treatment centers (HTCs); however, these can be difficult to access for some individuals. Previous SDOH research in this patient population has been limited; therefore, it can be difficult to identify the barriers to care that exist. There is a need to examine SDOH more thoroughly to create patient-directed interventions to improve access …

Reducing Antibiotic Duration For Pneumonia And Sinusitis In The Emergency Department: A Quality Improvement Approach, Joshua Saucedo, Leslie Hueschen, Amanda Nedved, Marsha Dannenburg, Patricia Phillips, Jennifer Floyd, Alaina N. Burns, Rana El Feghaly

Research Days

Background: Our aim is to increase the percentage of children discharged home from the ED with a diagnosis of CAP or ABRS treated with an optimal antibiotic duration (3-5 days for CAP, 5-7 days for ABRS) from 13% to 70% by July 25.

Methods: Outcome metric is the percentage of patients receiving recommended antibiotic duration for CAP and ABRS. Process metrics include use of order set, "Quick Discharge” order set, and clinical pathway QR codes. Balancing metric is the number of return visits with the same diagnosis < 14 days. Plan-Do-Study-Act methodology was used. In Aug 23, our ASP disseminated a handbook that emphasized shorter durations. A new multidisciplinary team (infectious diseases, ED, and urgent care physicians, advanced practice providers, nurses, and pharmacy) formed in Dec 23. We utilized cause-and-effect analysis, driver diagram, and prioritization matrix, which helped identify other impactful interventions, including implementation of new internal CAP clinical pathway order set (April 24) and “Quick Discharge” order sets (May 24). Next, we surveyed prescriber comfort (June 24) with shorter duration identifying barriers and providing education, leading to posted evidence for lower duration treatment in practitioner workrooms and developing a new ABRS clinical pathway (Sept 24). Top prescribers providing optimal duration received email acknowledgement (Oct 24) and resident rotators received antibiotic handbook and CAP clinical pathway QR codes (Nov 24). New best treatment practices for ABRS were elucidated and disseminated through clinical pathway and internal article publishing to our hospital and associated clinics (Dec 24).

Results: We saw shifts in the outcome metric’s center line in Sept 23 …

A Case Of Heterotaxy And Common Atrioventricular Canal With Bradycardia, Mohamed Aashiq Abdul Ghayum, Jenna Schermerhorn, Hayley S. Hancock, Kelsey Brattrud, Melanie Kathol, Maria Kiaffas

Research Days

Background

Heterotaxy-polysplenia syndrome (otherwise known as left atrial isomerism) should be suspected in the presence of complete atrioventricular canal defect (CAVC) with interruption of the inferior vena cava (IVC), atrioventricular block (AVB), and viscero-cardiac heterotaxy. The prognosis remains dismal for the fetus with such entity, especially in the presence of major structural heart disease and high-grade atrioventricular block. Early diagnosis, close follow up, and appropriate delivery planning, allows for effective stabilization of the baby after birth and might improve survival.
