The Potential Role Of Atn-161 As An Integrin Α5Β1 Inhibitor In Preventing Commonviral Infections, Peter Issa, H Wang, Ko Mcdonald, Be Ouvrier, Gj Bix

Medical Research Day

Integrins are transmembrane proteins which mediate many cellular signaling processes such as immunological function, extracellular matrix composition, apoptosis, and cell adhesion. In addition to these features, integrins have been implicated in viral infection. Integrin alpha5beta1, which has an arginine-glycine-aspartic acid (RGD) binding motif, has been shown to play a role in the pathogenesis of many viruses including porcine hemagglutinating encephalomyelitis virus (PHEV), human immunodeficiency virus (HIV-1), and severe acute respiratory syndrome- coronavirus 2 (SARS-CoV-2). However, a concise review of the role of integrin alpha5beta1 with regards to viruses and its potential as an antiviral therapeutic, especially with regards to SARS- …

Tropism Of Novel Aav Capsid Variants In The Inner Ear, Leigh C. Hickham, David Odenheimer, Grant Rauterkus, Sanford L. Boye, Shannon E. Boye, Jennifer J. Lentz

Medical Research Day

Background: Usher syndrome (Usher) is the leading genetic cause of combined deaf-blindness. Of the three clinical types, type 1 (USH1) is the most severe with congenital sensorineural hearing impairment and vestibular dysfunction, and adolescent onset of retinitis pigmentosa. While the genetics of Usher is well understood, the treatment options for these patients are limited. To fill this gap, we created a mouse model of Type 1C Usher (USH1C) that contains the splice site mutation (USH1C c.216G>A) responsible for USH1C in patients. USH1C mice have hearing, balance, and visual dysfunction similar to patients. Additionally, the expression of harmonin protein, encoded …

The Antibiotic-Resistant Bacteria Crisis: Overcoming Methicillin-Resistant Staphylococcus Aureus (Mrsa) By Myxobacterial Predation, Basirat Olorunlambe

Symposium of Student Scholars

With the growing threat of antibiotic-resistant bacteria, the need for finding new antibiotics is at an all-time high. According to the Center for Disease Control and Prevention (CDC), there were over 2.8 million cases of antibiotic-resistant infections in the United States in 2019 and over 35,000 individuals have died from them. Methicillin-Resistant Staphylococcus Aureus (MRSA) accounts for 323,700 of these cases, with 10,600 deaths. MRSA is a common cause of nosocomial infections. Although antibiotics are available to treat MRSA, such as Vancomycin, the possibility remains that these strains are likely to develop a resistance to these compounds as it has …

Anti-Vaxxers: Parents Fighting Science, Katie West

Symposium of Student Scholars

Immunizing children helps protect the health of our community, especially those people who cannot be immunized. Yet, since 1996 after a study was released that linked autism to vaccinations, there has been a trend of parents refusing to vaccinate their children. What are the demographics of the parents who believe their children are better off without vaccines? By knowing where these parents live and what decisions they make for their children’s education, counties and medical professionals can provide education and address their concerns.

My research involves data on 116,141 kindergarten classes from 2000-2015 in California. The two vaccine exemption options …

Cervical Cancer: Are There Ways To Reduce The Risks?, Madelyn Dorn

Symposium of Student Scholars

History has shown us that when caught early, cervical cancer is curable. Past research has found that the sexually transmitted diseases (STDs), herpes and human papillomavirus (HPV), have been associated with cervical cancer. In contrast, my dataset on 859 women has many more STDs and lifestyle choices compiled on 36 variables. The diagnoses in the dataset are many: cervical condylomatosis, vaginal condylomatosis, vulvo-perineral condylomatosis, syphilis, pelvic inflammatory disease, genital herpes, molluscum contagiosum, acquired immune deficiency syndrome (AIDS), human immunodeficiency virus (HIV), hepatitis B, HPV, and cervical cancer. In addition to the demographic variable on age, there are many lifestyle choice …

Oral Minimal Model For Gestational Diabetes, Sarah Peters

Symposium of Student Scholars

Gestational diabetes is one of the most common issues that a pregnant woman encounters that could result in harm to both the woman and child. Due to this issue, the woman’s glucose and insulin levels should be carefully monitored throughout her pregnancy to assess the need for prescribed diabetic medication to help regulate those levels. In this research, the objectives is to develop a MATLAB computer program of the Oral Minimal Model, which is a model that can be used to estimate a person’s insulin sensitivity from an oral glucose tolerance test (OGTT) where plasma glucose and insulin levels are …

The Effects Of Estrogen In The Glucoregulatory Response To Exercise In Type 1 Diabetes, Mitchell James Sammut

Undergraduate Student Research Internships Conference

Regular exercise has shown to benefit the health of individuals with type 1 diabetes mellitus (T1DM). However, a barrier to regular exercise for this population is the fear of low blood glucose (BG) levels, also known as hypoglycemia. Hypoglycemia can result in short and long-term side-effects, such as recurring loss of consciousness or in severe cases death.

In non-diabetics, sex-related differences in fuel selection during exercise are well established. Women shift towards using fats as fuel whereas men rely mostly on sugars (i.e., carbohydrates) for energy production. Exercise during the luteal phase of the female menstrual cycle, where estrogen levels …

Characterizing The Heterogeneity Of Adult-Onset Leukoencephalopathy With Axonal Spheroids: A Digital Spatial Profiling Study, Peter Liu

Undergraduate Student Research Internships Conference

Adult-onset leukoencephalopathy with axonal spheroids (ALAS) is a group of hereditary, progressive, neurodegenerative disorders involving primarily the central nervous system white matter (WM). ALAS is characterized by patchy, asymmetrical myelin loss and axonal destruction in the WM, predominantly involving the frontoparietal regions. However, the asymmetrical and heterogenous involvement of different brain regions remains poorly characterized.

In this study, digital spatial profiling was performed to investigate the region-specific expressions of 60 proteins. Conventional immunohistochemistry methods was used validate intrepretation of probes. Using a high-plex and high-throughput method, we provide evidence of regional heterogeneity in ALAS, particularly involving key markers of microglia …

Generating Cisplatin Resistant Hpv-Positive Hnscc Cell Lines, Temitope Akintola

Undergraduate Student Research Internships Conference

Acquired or innate resistance to chemotherapy poses a significant challenge in the treatment of head and neck squamous cell carcinomas (HNSCC). HNSCCs are often treated with a combination of surgery, radiation and chemotherapy, with cisplatin being a standard-of-care chemotherapy drug. Human Papillomavirus (HPV) associated HNSCCs have better treatment outcomes and prognosis when compared to HPV- HNSCCs. However, a subset (15-20%) of HPV+ patients develop treatment resistant diseases. The purpose of this study is to generate in-vitro models of cisplatin resistance in five HNSCC cell lines. We aim to characterize the generated cells in order to identify target genes that may …

Use Of Artificial Intelligence To Identify Predictors Of Functional Outcomes In Patients With Facioscapulohumeral Muscular Dystrophy, Natalie K. Katz

Research Days

Background: Facioscapulohumeral muscular dystrophy (FSHD) is one of the most common forms of muscular dystrophy characterized by slowly progressive muscle weakness. Symptoms initially involve the facial and shoulder girdle muscles, with later involvement of the distal lower extremities, pelvic girdle and proximal lower extremities. FSHD type 1 (FHSD1) is the most common form (~95% of individuals) and is caused by deletion of microsatellite repeats in the D4Z4 region on chromosome 4 (4q35). Normal individuals have >10 repeats whereas individuals with FSHD1 have 1-10 repeats. There is significant variability in regards to disease severity, rates of progression and functional outcomes, but …

Financial Outcomes Of High Flow Nasal Cannula Use For Bronchiolitis On The General Pediatric Floor Across Children's Hospitals, Jonathan Hartley

Research Days

Background: Bronchiolitis is a leading cause of hospitalization for infants and results in over 1.7 billion dollars in yearly hospital charges (Hasegawa). The use of high flow nasal cannula (HFNC) on a general pediatrics floor may reduce hospital costs and length of stay (LOS, Kalburgi). However, the financial impact of HFNC use is not welldescribed.

Objective: The primary objective are the financial outcomes of HFNC utilization on the general pediatric floor. The secondary objective included financial outcomes stratified by All Patients Refined Diagnosis Related Groups (APRDRG) severity of illness (SOI) and payor type. We hypothesize that costs outweigh reimbursement for …

Impact Of High Flow Nasal Cannula On Resource Utilization In Bronchiolitis, Scott Biggerstaff

Research Days

Background: Bronchiolitis is one of the most common diseases requiring hospitalization in children 1-24 months of age, but presently treatment is primarily supportive. High flow nasal cannula is a newer method of oxygen delivery pediatric hospitals have been rapidly adopting to treat respiratory insufficiency caused by viral bronchiolitis.

Objectives/Goal: We sought to compare resource utilization, including cost, length of stay (LOS), and readmission among children who were treated with HFNC versus those who were not.

Methods/Design: In this cross-sectional, multicenter study, we obtained clinical and resource utilization data from the Pediatric Health Information System (PHIS) database for otherwise healthy children …

A Case Series Of Hyperglycemic Hyperosmolar State During The Global Covid-19 Pandemic, Benjamin Hoag

Research Days

Background: Hyperglycemic hyperosmolar state (HHS) is rare in pediatrics, particularly in patients with antibody positive diabetes mellitus (DM). Recent literature has implicated COVID-19 in the reported increase in new onset DM cases, as well as mixed diabetic ketoacidosis (DKA) and HHS cases; however, a rise in HHS cases alone has not been well reported [1,2]. We noted an anecdotal increase in the frequency of HHS cases in our pediatric tertiary care center following the onset of the global COVID-19 pandemic.

Objectives/Goal: To investigate further, a retrospective chart review evaluating all patients with DM admitted in the first 6 months of …

Antibiotic Durations For Skin And Soft Tissue Infections In Pediatric Urgent Care Clinics, Megan Hamner

Research Days

Background: Skin and soft tissue infections (SSTIs) are the second most common diagnosis leading to pediatric antibiotic prescriptions in the outpatient setting after respiratory diagnoses. However, most antibiotic stewardship programs have mainly focused on the latter. Children seen in the ambulatory setting for SSTIs often receive >7 days of antibiotics, although current society guidelines recommend 5-7 days for most diagnoses.

Objectives/Goal: To determine the baseline percentage of patients receiving antibiotic prescriptions for >7 days for SSTIs in Children’s Mercy urgent care clinics (UCC)s and to evaluate factors that influence providers towards longer durations.

Methods/Design: We built a report that extracted …

A Study Examining The Safety And Efficacy Of Ferric Carboxymaltose In A Large Pediatric Cohort, Chandni Dargan Md, David Simon Do

Research Days

Background: Iron deficiency anemia (IDA) is common in the pediatric population with varying high-risk factors. Intravenous (IV) iron supplementation has become more desirable in patients with moderate to severe anemia and in patients who are either unresponsive to or have adverse side-effects secondary to oral iron. Iron sucrose and Iron dextran have been traditionally used in pediatrics while ferric carboxymaltose (FCM) has only been FDA approved in adults. One of the major advantages of FCM is the ease of dosing and efficacy. Though FCM was approved for adults in 2013 and there have been no safety concerns, it is not …

Bleeding Disorder Referrals To Hematology Clinic: A Single Institution Experience, Zuri Hudson

Research Days

Background: Our center receives hundreds of referrals yearly for bleeding disorder evaluation both due to bleeding symptoms and secondary to routine preoperative laboratory testing. The evaluation for a bleeding disorder can be challenging due to the wide variability of symptoms as well as the need for accurately interpreting lab results. Bhasin et al showed that 4% of patients referred to hematology based on a preoperative coagulation evaluation had a clinically relevant bleeding disorder. Currently there is little published about the referral patterns to pediatric hematology and the outcomes of these referrals.

Objectives/Goal: To characterize our hematology referrals for bleeding disorder …

Outcomes Of Infants With Severe Rop At Risk Of Treatment With Avastin Compared To Laser Surgery, Stephen Doxey

Research Days

Background: Retinopathy of prematurity (ROP) is a well-known complication occurring in the most premature infants leading to visual impairment and in the most severe cases associated with retinal detachment and childhood blindness. Factors contributing the development of ROP include chronic hypoxia and disordered vascular genesis primarily through the vascular endothelial growth factor (VEGF) signaling pathway. Infants at risk of developing ROP are screened with serial eye exam and treated with either laser surgery or intraocular injects of bevacizumab (Avastin) to prevent progression of ROP and preserve vision. Bevacizumab, an inhibitor of VEGF signaling, may have positive effects on preventing ROP …

Low Dose Doxorubicin Inhibits Immune Checkpoint Upregulation In Acute Leukemias, Bradley C. Stockard

Research Days

Background: Evasion of drug and immune response in therapy-resistant leukemic stem cells (LSCs) is a major cause of relapse. A previous study has identified an alternative mechanism of action for low-dose doxorubicin (DXR) that inhibits upregulation of immune checkpoints (IC) in LSCs.

Objectives/Goal: The objective of this study is to establish the DXR dose range that will achieve the inhibition of immune checkpoint expression in leukemic cell lines.

Methods/Design: Cells were analyzed for expression of CTLA-4, LAG-3, PD-1, TIGIT, and TIM-3 via flow cytometry. Analysis was performed on days 3, 5, and 8 of treatment at concentrations identified as low, …

Atrial Standstill In A Pediatric Patient With Scn5a Mutation Following Procainamide Challenge, Anmol Goyal

Research Days

Background: Atrial standstill (AS) is a rare arrhythmia characterized by absence of electrical and mechanical atrial activity associated with SCN5A channelopathy.

Case: An 18 year old male with structurally normal heart, frequent sinus pauses, nonsustained atrial tachycardia and high-grade block was found to have SCN5A mutation c.3823G>A (p.Asp1275Asn). An electrophysiology study (EPS) with high density voltage mapping of the right atrium was done (Fig 1a). Nonsustained multifocal atrial tachycardia was induced without ablative targets (Fib 1b). Procainamide challenge was negative for Brugada, however induced AS (Fig 1c-d). No atrial capture could be achieved at maximal output. Empiric atrial lead …

A Pediatric Case Of Treatment-Related Myelodysplastic Syndrome While On Therapy For Pre-B All, Sara Mcelroy

Research Days

Background: Treatment-related myelodysplastic syndrome (t-MDS) is a known, but rare, late effect of cancer therapy, specifically radiation, alkylating agents or topoisomerase II inhibitors. When secondary to treatment with alkylating agents, t-MDS typically occurs 4 to 7 years after therapy, and common cytogenetics include chromosomes 5 and 7 abnormalities. Treatment in children with t-MDS is typically allogeneic stem cell transplant, but the prognosis remains poor.

Objectives/Goal: To describe a rare case of a pediatric patient who developed t-MDS while receiving treatment for Pre-B Cell Acute Lymphoblastic Leukemia (pre-B ALL) and to outline the treatment regimen that he received.

Methods/Design: Case Report …

Reconsidering Perioperative Antibiotic Use In Elective Laparoscopic Cholecystectomy, Kayla B. Briggs

Research Days

Background: As rates of antimicrobial resistance increase, the use of prophylactic perioperative antibiotics (PPA) has been questioned in cases with a low risk of surgical site infection (SSI). In laparoscopic cholecystectomy performed for biliary dyskinesia, hyperkinetic gallbladder, and gallbladder polyps, the use of PPA varies with no widely accepted practice pattern.

Objectives/Goal: We examined institutional PPA usage and SSI rates for elective laparoscopic cholecystectomy to determine if PPAs are indicated.

Methods/Design: Following IRB approval, children/2010 and 8/2020 for symptomatic cholelithiasis, biliary dyskinesia, hyperkinetic gallbladder, and/or gallbladder polyps were included. Several surgeons changed practice to selective PPA use in 2016, decreasing …

The Role Of Fractionated Exhaled Nitric Oxide (Feno) In Eosinophilic Esophagitis And The Relationship With Downstream Eosinophils, Panamdeep Kaur

Research Days

Background: Eosinophilic Esophagitis (EoE) is a chronic immune mediated disease of the esophagus characterized by symptoms of esophageal dysfunction and eosinophilic-predominant inflammation of the esophagus. It can lead to feeding difficulties, failure to thrive, and esophageal stricturing. Currently, the gold standard for diagnosis and assessing response to therapy is upper endoscopy and histopathological analysis of biopsies. A noninvasive, cost-effective, and low risk alternative that can aid in the management of EoE is not currently available. Previous studies assessing correlation of fractionated exhaled nitric oxide (FeNO) with degree of esophageal eosinophilic inflammation were low powered but noted a trend for association. …
