Plasma Resuscitation Attenuates Intestinal Barrier Disturbance Following Hemorrhagic Shock., Jessica E. Schucht
Plasma Resuscitation Attenuates Intestinal Barrier Disturbance Following Hemorrhagic Shock., Jessica E. Schucht
Electronic Theses and Dissertations
Background: Intestinal ischemia-reperfusion injury (IIRI) following resuscitated hemorrhagic shock (HS/RES) leads to endothelial damage, microcirculatory dysfunction and intestinal barrier breakdown, increasing intestinal permeability. This pathologic process contributes pathophysiology of multiple organ dysfunction syndrome (MODS) in some trauma patients. Although vascular smooth muscle machinery remains intact, microvascular vasoconstriction occurs secondary to endothelial cell damage, resulting in further ischemia and organ injury. Used separately, resuscitation with Fresh Frozen Plasma (FFP) or Direct Peritoneal Resuscitation (DPR) improves the intestinal microcirculation and alleviates organ injury. Further examination of these effects individually or combined could aid in the resuscitation of hemorrhagic shock. Methods: Sprague Dawley …

Healthcare Barriers For Congolese Refugee Children In Louisville, Ky: Parental Perception And Narratives Through Focus Group Discussions, Zheyi Teoh, Brit Anderson, Annie Rominger
Journal of Refugee & Global Health
Background: There are up to 3500 refugees who resettle in Kentucky annually with 66% of refugee children originating from the Democratic Republic of the Congo. Little is known about the barriers to healthcare perceived by Congolese parents. This information can direct interventions to improve the care of these children.
Methods: Focus group discussions (FGD) were used to allow families to share personal anecdotes, compare experiences, and encourage discussion between group members. Between August 2018 to May 2020, three FGDs were conducted with Congolese parents who have at least one child ≤18 years old. An interpreter was utilized for each session …
Gender Identity And Pronoun Usage In Standardized Patient Encounters, Martha M. Popescu, Emily J. Noonan, Laura A. Weingartner
Gender Identity And Pronoun Usage In Standardized Patient Encounters, Martha M. Popescu, Emily J. Noonan, Laura A. Weingartner
Undergraduate Research Events
The standardized documentation clinicians use to record evaluations of a patient are called Subjective, Objective, Assessment, and Plan (SOAP) notes. Consistent pronoun documentation and usage in these notes is especially important for affirming transgender and gender non-conforming patients as this population experiences significant health disparities linked to medical mistrust. A sample of SOAP notes (n=286) was taken from standardized patient encounters at the University of Louisville School of Medicine in 2017 (n=137) and 2018 (n=149). There were five case iterations of the standardized patient based on gender identity. The notes were coded using the software Dedoose for the following themes: …
Promoting Resident Emotional Health Meaningful Connections: An Evaluation Of A Wellness Game, Bruce St. Amour, William B. Dehart
Promoting Resident Emotional Health Meaningful Connections: An Evaluation Of A Wellness Game, Bruce St. Amour, William B. Dehart
Journal of Wellness
Introduction
Physician wellness is a topic of significant national interest. Physician burnout is at its highest point during residency and is linked to many negative outcomes. The Core Emotional Needs are a useful framework to guide thinking toward wellness in residents: connection and acceptance, healthy autonomy and performance, reasonable limits, and healthy responsibility and standards. We examined the efficacy of a game (“Well, For Me…”) designed to improve social connection and acceptance among residents to reduce social isolation. We hypothesized that this activity would be viewed positively by the residents as an intervention to improve resident wellness.

Looking Beyond A Rare Presentation Of Betel Nut Use In A North American Patient- An Opportunity For Lessons And Intervention In Global Health And Gender Equity, Muhammad O. Zaman, Thomas M. Park, Vikas Patel, Riley G. Jones
Looking Beyond A Rare Presentation Of Betel Nut Use In A North American Patient- An Opportunity For Lessons And Intervention In Global Health And Gender Equity, Muhammad O. Zaman, Thomas M. Park, Vikas Patel, Riley G. Jones
Journal of Refugee & Global Health
Betel nut is estimated to be the fourth most common psychoactive substance used globally behind caffeine, alcohol, and nicotine with 600 million global users. Betel nut use has a strong association with oral cancer and many other systemic effects including oral submucosal fibrosis. Although North American use is rare, its enduring effects may surface long after use posing a diagnostic challenge to practitioners caring for an increasingly global diaspora. Herein, we present a patient with severe trismus due to advanced oral submucosal fibrosis who was unexpectedly found to be importing and using Betel nut for over thirty years after immigrating. …

Gaining A “Foothold” On The Diagnosis Of Leishmaniasis, Brent M. Troy, Rebecca Hart, Navjyot Vidwan, Bethany Hodge
Journal of Refugee & Global Health
Pediatric refugees and immigrants may present with unusual diagnoses due to their extensive migration and potential harsh conditions in travel. Trauma and family separation add to the difficulty of obtaining a history of exposures. We report a case of one of the more commonly neglected tropical diseases, Leishmaniasis. A 15-year-old male refugee patient presented to the hospital with ulcerative lesions to his legs. His migration history was extensive, starting in Central Africa with travel to South America, followed by migration through Central America to Texas. The patient developed ulcerative lesions on his legs, and he was brought to the children’s …
Factor Structure And Measurement Invariance Of The Maslach Burnout Inventory In Emergency Medicine Residents, Tim P. Moran, Nicole Battaglioli, Simiao Li-Sauerwine
Factor Structure And Measurement Invariance Of The Maslach Burnout Inventory In Emergency Medicine Residents, Tim P. Moran, Nicole Battaglioli, Simiao Li-Sauerwine
Journal of Wellness
Introduction: Emergency medicine residents suffer from high rates of occupational burnout. Recent research has focused on identifying risk and protective factors for burnout as well as targets for intervention. This research has primarily employed the Maslach Burnout Inventory to evaluate burnout in this population. Factor analytic work has identified three underlying factors measured by the Maslach Burnout Inventory: Emotional Exhaustion, Depersonalization, and Personal Accomplishment. However, this three-factor structure has not been evaluated in emergency medicine residents. Furthermore, its structural equivalence has not been demonstrated across commonly-studied risk factors, such as gender and year of post-graduate training. In the present study, …
Plasmodium Impairs Antibacterial Innate Immunity To Systemic Infections In Part Through Hemozoin-Bound Bioactive Molecules., Christopher Lynn Harding
Plasmodium Impairs Antibacterial Innate Immunity To Systemic Infections In Part Through Hemozoin-Bound Bioactive Molecules., Christopher Lynn Harding
Electronic Theses and Dissertations
Despite efforts to decrease the global health burden of malaria, infections with Plasmodium species continue to cause over 200 million episodes of malaria each year which resulted in 405,000 deaths in 2018 [1]. One complication of malaria is increased susceptibility to invasive bacterial infections. Plasmodium infections impair host immunity to non-Typhoid Salmonella (NTS) through activities of heme oxygenase I (HO-I) )-induced release of immature granulocytes and myeloid cell-derived IL-10. Yet, it is not known if these mechanisms are specific to NTS. We show here, that Plasmodium yoelii 17XNL (Py) infected mice had impaired clearance of systemic Listeria monocytogenes (Lm) during …

The University of Louisville Journal of Respiratory Infections
Introduction: The large volume of diagnostic tests required by the response to the COVID-19 pandemic resulted in a shortage of commercial nasopharyngeal swabs. In an effort to alleviate the shortage, swabs created by 3D printing may be a solution.
Methods: We designed and produced 3D printed swabs and sought to compare their ability to detect SARS-CoV-2 in patients admitted for COVID-19 or who were suspected of having COVID-19.
Results: A total of 30 patients were swabbed with a commercial and a 3D printed swab. Results matched in 27 of 30 patients (90%). Two patients were discordant with a positive commercial …

The University of Louisville Journal of Respiratory Infections
The novelty and uncertainty associated with COVID-19 has created challenges for politicians, citizens, and healthcare providers, leaving no one unaffected. As members of the front line of defense, providers in Emergency Departments (EDs) face the momentous challenge of effectively identifying and treating patients with COVID-19, working with experts in Infectious Disease, Internal Medicine, Critical Care, Public Health, and other disciplines. We must coordinate these efforts while also protecting staff, implementing strategies to reduce transmission, and managing ED patients with conditions unrelated to COVID-19. Striving to maintain a grasp of the rapidly accumulating publications in medical journals and the media, we …

Introduction: Liver disease and cirrhosis are common causes of mortality worldwide. Community-acquired pneumonia is recognized as a significant cause of morbidity and mortality in this population of adults. There is a lack of data regarding outcomes or prognosis in patients with liver dysfunction who develop CAP. The objective of this study was to evaluate the clinical characteristics, incidence, and outcomes of hospitalized patients with CAP and liver disease.
Methods: This was a secondary analysis of the University of Louisville Pneumonia Study, which was a prospective population-based cohort study of adults hospitalized with community-acquired pneumonia. All patients were divided into three …
The Role Of Slc7a11 In Controlling Extracellular And Intracellular Redox Environments Of Lung Fibroblasts - Potential Targets For Intervention In Aging And Idiopathic Pulmonary Fibrosis., Yuxuan Zheng
Electronic Theses and Dissertations
Idiopathic pulmonary fibrosis (IPF) is a fatal lung disease characterized by extracellular matrix deposition by fibroblasts. Aging and oxidative stress increase the susceptibility to IPF. Redox couples, cysteine/cystine (Cys/CySS) and glutathione/glutathione disulfide (GSH/GSSG), and their redox potentials (Eh) quantify oxidative stress. Fibroblasts from old mice maintain more oxidized extracellular Eh(Cys/CySS) than young mice. Microarray shows down-regulation of Slc7a11 potentially mediates this age-related oxidation. Slc7a11 is the key component of system Xc-, an antiporter that imports CySS and exports glutamate. The first aim of this dissertation is to investigate the mechanistic link between Slc7a11 …
Novel Inference Methods For Generalized Linear Models Using Shrinkage Priors And Data Augmentation., Arinjita Bhattacharyya
Novel Inference Methods For Generalized Linear Models Using Shrinkage Priors And Data Augmentation., Arinjita Bhattacharyya
Electronic Theses and Dissertations
Generalized linear models have broad applications in biostatistics and sociology. In a regression setup, the main target is to find a relevant set of predictors out of a large collection of covariates. Sparsity is the assumption that only a few of these covariates in a regression setup have a meaningful correlation with an outcome variate of interest. Sparsity is incorporated by regularizing the irrelevant slopes towards zero without changing the relevant predictors and keeping the resulting inferences intact. Frequentist variable selection and sparsity are addressed by popular techniques like Lasso, Elastic Net. Bayesian penalized regression can tackle the curse of …

Background
HIV-positive patients on anti-retroviral therapy (ART) are at higher risk of developing many non-AIDS related chronic diseases, including chronic obstructive pulmonary disease (COPD), compared to HIV-negative individuals. While the mechanisms are not clear, a persistent pro-inflammatory state appears to be a key contributing factor. The aims of this study were to investigate whether HIV-positive patients without COPD present evidence of potentially predisposing abnormal pulmonary cytokine/chemokine environment and to explore the relationship between pulmonary and systemic cytokine levels.
Methods
This study included 39 HIV-seropositive and 34 HIV-seronegative subjects without COPD. All were subjected to outpatient bronchoscopy with bronchoalveolar lavage fluid …
