Variation In Thiopurine Metabolism In Hispanic Children, Kayeleigh Higgerson Do

Research Days

Background: Acute lymphoblastic leukemia (ALL) is the most common childhood cancer. Overall survival rate is > 90% in the United States. However, ethnic and racial disparities remain. Hispanic patients have an inferior overall survival compared to non-Hispanics. The reasons for these differences remain unclear. Mercaptopurine (6MP) is a crucial drug in ALL treatment. Variations in the TMPT and NUDT15 genes lead to altered 6MP metabolism and accumulation of toxic metabolites (6TGN or 6MMPN). Each metabolite is associated with specific dose-limiting toxicities. The accumulation of 6TGN causes myelosuppression, and increased 6MMPN causes GI toxicity. While variants in these genes have been identified …

Methods/Design: Case Report

Results: The patient is an 11-year-old female diagnosed with Wilms …

Wilms Tumor Presenting With Spontaneous Necrosis And Clostridium Perfringens Co-Infection, Ronald Palmen, Abbey Elsbernd, Kristin Palmen

Research Days

Background: Wilm’s Tumor (WT) is the most common renal malignancy of childhood. The initial presentation of WT may mimic infection or other malignancies with nonspecific symptoms including fever, abdominal/flank pain, or hematuria. This poses a diagnostic challenge for providers, particularly when both infection and malignancy are observed. We describe a case of WT with spontaneous necrosis initially obscured by overlying Clostridium perfringens infection, making diagnosis of the cancer difficult.

Case Description: A previously healthy 5-year-old girl presented to the emergency department with a two-day history of left flank pain and fevers. In the emergency department, she was tachycardic (130 bpm), …

Investigating Active Learning Through The Lens Of Student Engagement, Nicole Naibert

Dissertations and Theses

Incorporating active learning into a course has been generally found to lead to improved student learning outcomes; however, not all students benefit from these environments to the same extent. Although active learning environments provide the opportunity for students to interact and engage with the material, whether a student decides to do so is completely up to them. Therefore, the goal of this dissertation was to begin exploring active learning environments through the lens of student engagement and relevant associated variables (i.e., self-efficacy and student perceptions). This was completed through three separate but related projects.

Project I focused on investigating flipped …

Factors Leading To Reduced Unscheduled Pediatric Asthma Visits During Covid-19, Sean Stout

Research Days

Background: Emergency Department (ED) and inpatient (IP) asthma visits were reduced during 2020 at a tertiary pediatric hospital. This was likely due to measures used to avoid exposure to the SARS-CoV2 virus which led to fewer viral upper respiratory infections (URIs). Other known asthma triggers include allergens, air pollution, and weather changes.

Objectives/Goal: To determine whether other factors could explain this reduction, we looked for changes in other asthma triggers such as pollen, air pollution, and weather.

Methods/Design: Monthly ED and IP asthma visits from 2010 to 2019 were compared to 2020 by time series analysis (TSA), controlling for total …

An Analysis Of Non-Comparison Based Sorting Algorithms, Jacob M. Gomez, Edgar Aponte, Brad Isaacson

Publications and Research

Sorting algorithms put elements of a list into an order (e.g., numerical, alphabetical). Sorting is an important problem because a nontrivial percentage of all computing resources are devoted to sorting all kinds of lists. For our project, we implemented two non-comparison based sorting algorithms from pseudocode and compared them to various comparison based sorting algorithms. The two algorithms have their advantages and disadvantages as well as their unique features. We found that Radix Sort (which is a modified version of Counting Sort) was the most efficient of them all.

Increased Prevalence Of Parenteral Nutrition-Associated Liver Disease In Neonates With Congenital Heart Disease, Yasasvhinie Santharam

Research Days

Background: A life-sustaining therapy, use of total parenteral nutrition (TPN) allows for meeting nutritional needs of low birth weight, premature, or otherwise complex infants with conditions that prevent feeding through the GI tract. However, 40-60% of infants on long-term TPN have been shown to develop parenteral nutrition-associated liver disease (PNALD)1 , a serious condition characterized by cholestatic jaundice, steatosis, and hepatic fibrosis. Given these risks, providers must account for risk of hepatic injury when prescribing TPN, including attributes of gestational age, infection, surgical and diagnosis history2-6 . Yet with a multifactorial pathogenesis, significant heterogeneity in PNALD incidence still occurs. Looking …

The Effects Of Necrotizing Enterocolitis And Short Chain Fatty Acids On The Developing Brain In Mice, Maribel Martinez, Venkatesh Sampath, Paula Nichols, Wei Yu, Suban Burale, Tianhua Lei

Research Days

Background: Necrotizing enterocolitis (NEC) is a devastating disease in premature infants characterized by acute intestinal inflammation and necrosis with a mortality of 15%-30%. Approximately 50% of infants that survive NEC will develop neurodevelopmental defects[1]. Studies on the effects of NEC on the neonatal brain are limited, however it’s postulated that neurodevelopmental damage is induced via cytokine activation of toll-like-receptor 4 (TLR4) by high mobility group box protein 1 (HMGB1) on the microglia Accumulation of reactive oxygen and demyelination contribute to neuronal damage. Therapies that limit the development of NEC can potentially also limit the neuroinflammatory changes seen in NEC[2]. We …

Repeat Tracheal Aspirates In Pediatric Intensive Care Patients: Understanding Clinical Application, Edward Lyon

Research Days

Background: Tracheal aspirate cultures (TA) are regularly obtained in the pediatric intensive care unit (PICU) when clinical changes in intubated or tracheostomy dependent children occur. Positive TA results are often unable to distinguish infection from colonization. There is no data describing the frequency and impact of repeated TAs on patients in the PICU.

Goal: Our objectives were to describe the frequency of repeated TAs in PICU children and emergence of multidrug resistant organisms (MDRO), identify bacterial profile of TAs, and examine antibiotic prescribing patterns related to these cultures.

Methods: A retrospective chart review occurred on 15 patients in the PICU …
