Mortality From Aspiration Pneumonia: Incidence, Trends, And Risk Factors, Trisha Gupte, John D. Cramer M.D., Arthur Knack Phd, Ccc-Slp

Medical Student Research Symposium

Aspiration pneumonia is a potentially preventable, aggressive type of pneumonia. Little is understood on the burden in mortality from aspiration pneumonia. Our objectives were to first examine the burden of mortality from aspiration pneumonia in the United States and second investigate comorbidities associated with aspiration pneumonia to understand risk factors. We conducted a case-control study of individuals who died of aspiration pneumonia matched to those who died of other causes. We analyzed all deaths in the United States using the Multiple Cause of Death Dataset from 1999-2017. Cases were matched with controls based on age, sex, and race. We calculated …

Meta-Analysis Of 175 Patients With Covid-19 And Seizures, Status Epilepticus, Or Cortical Myoclonus: An Individual Patient Data Analysis, Aditi Kappagantu Bs, Helena A. Brantz Ms, Amman Bhasin Ba, Cristina Jageka Bs, Rooqash Ali Md, Izzy Saef Md, Brittany M. Stopa Mph, Ayaz Khawaja Md

Medical Student Research Symposium

Objective

To characterize management and outcomes of seizures, status epilepticus, and cortical myoclonus in COVID-19, with individual patient data analysis of published literature.

Methods

Systematic literature review was conducted in accordance with PRISMA guidelines. Criteria included new-onset seizures, status epilepticus, and/or cortical myoclonus with concomitant COVID-19. COVID-19 severity was dichotomized into mild and severe cases. Good outcome was defined as discharge without severe deficits, and/or return to baseline.

Results

A total of 105 studies reporting 176 patients (male 56.3%;mean age 47.8,SD 25.6) were included. Status epilepticus occurred in 47 patients (26.7%) and myoclonus in 41 (23.3%). Severe COVID-19 occurred in …

Lysosomal Zn 2+ Release Triggers Rapid, Mitochondria-Mediated, Non-Apoptotic Cell Death In Metastatic Melanoma, Wanlu Du, Mingxue Gu, Meiqin Hu, Timothy Nold, Prateeksunder Pinchi, Wei Chen, Michael Ryan, Ahmed Bannaga, Haoxing Xu

Medical Student Research Symposium

During tumor progression, lysosome function is often maladaptively upregulated to match the high energy demand required for cancer cell hyper-proliferation and invasion. Here, we report that mucolipin TRP channel 1 (TRPML1), a lysosomal Ca2+ and Zn2+ release channel that regulates multiple aspects of lysosome function, is dramatically upregulated in metastatic melanoma cells compared with normal cells. TRPML-specific synthetic agonists (ML-SAs) are sufficient to induce rapid (within hours) lysosomal Zn2+-dependent necrotic cell death in metastatic melanoma cells while completely sparing normal cells. ML-SA-caused mitochondria swelling and dysfunction lead to cellular ATP depletion. While pharmacological inhibition or genetic silencing of TRPML1 in …

Attitudes And Barriers Toward Covid-19 Vaccination Among People Experiencing Homelessness In Detroit, Mi, Sanjna Ghanshani, Sophie Wittenberg, Richard Bryce

Medical Student Research Symposium

Introduction: People experiencing homelessness (PEH) have a high risk of exposure to communicable diseases and limited access to health care services and treatment in their communities. Despite the availability of highly effective vaccines against COVID-19, the infection prevention practices and level of COVID-19 vaccine hesitancy among PEH in Detroit have not been well studied.

Methods: Medical students administered an electronic Qualtrics survey to consented participants during outreach visits to local homeless shelters and encampments organized by Street Medicine Detroit. The questionnaire comprised six topics, including hygiene and masking practices, experience with COVID-19 testing and vaccination, and attitudes toward …

Identifying Predictors For Inflammation-Induced Preterm Birth: A Murine Study, Tzu Ning Liu Bs, Jose Galaz Md, Nardhy Gomez-Lopez Phd

Medical Student Research Symposium

Introduction: Preterm birth is the leading cause of neonatal morbidity and mortality worldwide. A large proportion of preterm deliveries is affected by intra-amniotic inflammation, which can occur in the presence (intra-amniotic infection) or absence (sterile intra-amniotic inflammation) of microbes. Studies have shown an association between intra-amniotic inflammation, cervical shortening, and changes in the cervicovaginal microbiome. However, their causal relationships are unknown. This study aims to determine the causality of intra-amniotic inflammation, cervical shortening, and cervicovaginal microbiome alterations.

Methods: Pregnant C57BL/6 dams received an ultrasound-guided intra-amniotic injection of an endotoxin lipopolysaccharide (LPS) or the alarmin interleukin-1 alpha (IL-1 alpha) on 16.5 …

Complications Of Pediatric Cochlear Implant Surgery, Andrew Stefan, Sabrina Bernardo, William Azkoul Ii, Bianca Siegel

Medical Student Research Symposium

Background:

Cochlear implantation (CI) surgery is the standard of care treatment for pediatric patients diagnosed with severe to profound sensorineural hearing loss. While considered a relatively safe operation, any invasive procedure involving the cranium has risks. However, there are few recent studies in the United States that have analyzed complication rates among children who have received CI. Furthermore, existing studies fail to discuss specific risk factors that led to post-operative complications, nor offer solutions to reduce their incidence. This study aims to 1) determine the incidence of specific complications in pediatric CI patients and 2) identify evidence-based risk factors for …

Thromboelastography Profiles Of Hemophilia A Patients On Emicizumab, Daniel J. Vanzweden, Meera Chitlur, Charity J. Stadler

Medical Student Research Symposium

Emicizumab is a new monoclonal antibody developed to dtreat people with Hemophilia A, especially those with antibodies. However, breakthrough bleeding can still occur in patients taking Emicizumab. TEG is a global coagulation assay which measures coagulability through viscosity. This study describes the use of tissue factor activated TEG in measuring bleeding profiles in patients taking Emicizumab. The goal of this prospective study is to determine if TEG can be used, which variables of TEG might be useful, and how much more useful it is than the current standard, aPtt. Findings include a 25% increased R time and 24% increased K …

Corticosteroid Injection Exhibits Symptomatic Improvement In Cts Patients With Negative Emgs, Brooke G. Garnica, Aaron R. Prater, Elizabeth A. Washnock-Schmid, Alaa Hazime, Dr. Charles S. Day

Medical Student Research Symposium

Introduction

While corticosteroid injections for carpal tunnel syndrome (CTS) are effective in patients with mild EMGs, no literature has examined the effectiveness of injections in patients with negative EMGs. We hypothesized that patients with negative EMGs will have minimal symptomatic and functional improvement.

Methods

The Boston Carpal Tunnel Questionnaire (BCTQ) was administered to patients clinically diagnosed with CTS and a negative or mild EMG prior to corticosteroid injection. The BCTQ comprises functional (FSS) and symptom status (SSS) questions. The patient was re-evaluated at 2-weeks, 1-, 3-, and 6-months post-injection. Data were analyzed via one-way ANOVA tests. A post-hoc Benjamini-Hochberg FDR …
