Infection Potential Of Rickettsia Felis Via Ingestion, Matthew M. Schexnayder

LSU Master's Theses

Rickettsia felis is the etiologic agent of flea-borne spotted fever (FBSF) in humans and a poorly described cause of fever in animals. It is transmitted by its primary arthropod vector and reservoir host, the cat flea Ctenocephalides felis. Known routes of Rickettsia felis transmission between Rickettsia felis-infected cat fleas and vertebrate hosts include cutaneous bites and contamination of cutaneous wounds with infective flea feces. The bulk of FBSF infections occur in young children in Africa, though infections of people at all ages all over the world have been confirmed. As mammals and young children frequently come into contact …

Strategies To Combat Drug-Resistant Tuberculosis: Inhalable Microparticles Formulated With Anti-Tubercular Antibiotics And Efflux Pump Inhibitors, Elliott K. Miller

Pharmaceutical Sciences ETDs

Mycobacterium tuberculosis (Mtb) is an intracellular pathogen which can remain dormant within the human body for years (latent tuberculosis), and once active requires extensive multidrug therapies for treatment. Long-term antibiotic(s) exposure have led to the emergence of multidrug-resistant (MDR) and extensively drug-resistant (XDR) strains which require novel treatment approaches to combat Mtb resistance. Mtb may also utilize efflux pumps to expel antibiotics and promote bacterial survival, potentially mediating drug tolerance, which has been hypothesized to contribute to antibiotic resistance. Efflux pump inhibitors (EPIs) such as verapamil (VER) may potentiate effects of first-line anti-tubercular drugs (ATDs) such as rifampicin …

Analysis Of Unplanned Extubations At A University Neonatal Intensive Care Unit., Elizabeth Turcotte

Doctor of Nursing Practice Papers

Unplanned extubations represent a serious adverse event that occurs within neonatal intensive care units. The current literature on unplanned extubations suggests that the incidence of these events can be reduced in the clinical setting. UEs represent the primary respiratory-related adverse event in the neonatal intensive care unit (NICU) and can result in cardiopulmonary collapse requiring emergent reintubation (Carvalho, Mezzacappa, Calil, & Machado, 2010). Staff members of the University of Louisville’s neonatal intensive care unit collected data surrounding unplanned neonatal extubations from November 2017 through December 2018. These data have been used to target modifiable risk factors temporally associated with unplanned …

A High Throughput Assay For The Detection Of Stimulator Of Interferon Genes (Sting) Agonists, Michael J. Ingling

Graduate School of Biomedical Sciences Theses and Dissertations

The innate immune system includes a menagerie of different cell types, each with a different role in the process of monitoring the body for invaders and presenting gathered debris (antigen) to the adaptive immune system. Somatic cells have intracellular receptors for the same purpose. Cancer cells, however, have avoided these methods of detection despite, in many cases, the tumor’s immunogenic traits. Immuno-oncology is a field dedicated to the immunological traits of tumors, more recently finding ways of instigating an immune response against tumors. In this regard, STING, a receptor of cyclic dinucleotides (CDN), has come to the forefront of immuno-oncology. …

Retrospective Study Demonstrating High Rates Of Sustained Virologic Response After Treatment With Direct-Acting Antivirals Among American Indian/Alaskan Natives, Jorge Mera, Kartik Joshi, Karla Thornton, Terry Box, John Scott, Miranda Sedillo, Paulina Deming, Crystal David, Whitney Essex, Richard Manch, Anita Kohli

Project ECHO Bibliography

BACKGROUND: Treatment for chronic hepatitis C virus (HCV) has rapidly evolved to simple, well-tolerated, all-oral regimens of direct-acting antivirals (DAAs). There are few data on the epidemiology of HCV in American Indians/Alaska Natives (AI/ANs), a population disproportionately affected by HCV.

METHODS: In this retrospective cohort study, all HCV-infected AI/AN patients treated with DAA therapies between January 1, 2014, and February 24, 2016, in specialty clinics or by primary care clinicians participating in Extension for Community Healthcare Outcomes (ECHO) were included. Demographic, clinical, and virologic data on all patients treated for HCV from pretreatment through sustained virologic response at 12 weeks …

Transmission Dynamics Of Toxoplasma Gondii In Arctic Foxes (Vulpes Lagopus): A Long-Term Mark-Recapture Serologic Study At Karrak Lake, Nunavut, Canada, Emilie Bouchard, Stacey A. Elmore, Ray T. Alisauskas, Gustaf Samelius, Alvin A. Gajadhar, Keaton Schmidt, Sasha Ross, Emily J. Jenkins

United States Department of Agriculture Wildlife Services: Staff Publications

Transmission dynamics of Toxoplasma gondii, a parasite of importance for wildlife and human health, are enigmatic in the Arctic tundra, where free-ranging wild and domestic felid definitive hosts are absent and rarely observed, respectively. Through a multiyear mark-recapture study (2011– 17), serosurveillance was conducted to investigate transmission of T. gondii in Arctic foxes (Vulpes lagopus) in the Karrak Lake region, Nunavut, Canada. Sera from adult foxes and fox pups were tested for antibodies to T. gondii by using serologic methods, including the indirect fluorescent antibody test, direct agglutination test, and modified agglutination test. The overall seroprevalence was 39% in adults …

Ion Gresser 1928-2019, Jan Vilcek, Howard A. Young

United States Public Health Resources

Ion Gresser, a virologist who transformed understanding of the roles of interferons, may be best remembered for showing that in mice, interferon-α (IFN-α) can produce acute and chronic disease. At the time Gresser began these studies, interferon was considered to be a selective antiviral substance, harmless to uninfected cells and organisms, and there was no indication that cytokines would play a role in pathogenesis. That belief was shattered with the 1975 Nature publication with the simple title “Lethality of interferon preparations for newborn mice.” Gresser subsequently demonstrated that antibodies to IFN-α can protect young mice from death caused by infection …

Engaging Crisis: Immersive, Interdisciplinary Learning In Mathematics And Rhetoric, Meredith Greer, Stephanie Kelley-Romano

All Faculty Scholarship

This paper describes an interdisciplinary activity that crosses over between Mathematics and Rhetoric. The professors who created this activity both sought active-learning opportunities for their students, a sense of realism--even urgency--in what can otherwise be perceived as abstract material, and a meaningful liberal arts experience. Evidence of the power of this experience is seen in the media coverage, both from our college and from the Portland Press Herald newspaper. Both courses described in this paper are at the elective level, taken by majors or minors in their respective disciplines. Students have moderate to extensive backgrounds in their subject areas. However, …

When An Infected Meniscus Portends A Perforated Viscus, Michelle Hannon, Stephen Zachariah, Neha Bansal Etherington, Anusha Govind, Devin Weber, Bryan Hess

Division of Infectious Diseases and Environmental Medicine Faculty Papers

A 59-year-old woman with a status of post–renal transplant 7 years prior for autosomal dominant polycystic kidney disease on tacrolimus and mycophenolate mofetil presented with subacute left knee and right wrist pain. She received local steroid injections to both areas as an outpatient without improvement in her symptoms. She had recently traveled to India, her home country, to visit relatives. Aspiration of the knee revealed 4+ acid fast bacilli on smear, and she was taken for surgical debridement. She was started on empiric antibiotics for presumed infection with rapidly growing mycobacteria. Her course was complicated by acute onset abdominal pain …

Clinical Emergency Care Research In Low-Income And Middle-Income Countries: Opportunities And Challenges, Adam R. Aluisio, Shahan Waheed, Peter Cameron, Jermey Hess, Shevin Jacob, Niranjan Kissoon, Adam C. Levine, Asad Mian, Shammi Ramlakhan, Hendry R. Sawe, Junaid Razzak

Department of Emergency Medicine

Disease processes that frequently require emergency care constitute approximately 50% of the total disease burden in low-income and middle-income countries (LMICs). Many LMICs continue to deal with emergencies caused by communicable disease states such as pneumonia, diarrhoea, malaria and meningitis, while also experiencing a marked increase in non-communicable diseases, such as cardiovascular diseases, diabetes mellitus and trauma. For many of these states, emergency care interventions have been developed through research in high-income countries (HICs) and advances in care have been achieved. However, in LMICs, clinical research, especially interventional trials, in emergency care are rare. Furthermore, there exists minimal research on …

Development Of A Prolyl Endopeptidase Expression System In Lactobacillus Reuteri To Reduce The Clinical Manifestation Of Celiac Disease, Kara Lynn Jew

Master's Theses

Celiac Disease (CD) is an autoimmune disorder that emerges due to the ingestion of gluten, a protein found in a variety of common grains such as wheat, rye, and barley. Approximately 1 in 100 individuals in the US suffer from CD, making it the most commonly diagnosed gastrointestinal disorder (Ciclitira et. al., 2005). These proline-rich gluten peptides are resistant to proteolysis and accumulate in the duodenum of the small intestine. Once in the duodenum, these peptides illicit an autoimmune response resulting in villous atrophy. Current treatment for CD requires a rigorous adherence to a gluten-free diet. Nevertheless, gluten-containing grains are …

Maternal Childhood And Lifetime Traumatic Life Events And Infant Bronchiolitis, Margaret A. Adgent, Omar Elsayed-Ali, Tebeb Gebretsadik, Frances A. Tylavsky, Mehmet Kocak, Stephania A. Cormier, Rosalind J. Wright, Kecia N. Carroll

Faculty Publications

© 2019 John Wiley & Sons Ltd Background: Viral bronchiolitis is a common respiratory infection that often affects term, otherwise healthy infants. A small literature suggests maternal stress during pregnancy is associated with bronchiolitis. However, the association between maternal exposure to lifetime traumatic stress, including traumatic events occurring in childhood or throughout the life course, and bronchiolitis has not been studied previously. Objectives: To investigate the association between maternal exposure to total lifetime and childhood traumatic stress events and infant bronchiolitis. Methods: We studied mother-infant dyads enrolled in a prospective prenatal cohort, recruited 2006-2011, and Tennessee Medicaid. During pregnancy, we …

Comparison Of The Sequential Organ Failure Assessment (Sofa) And Quick Sofa Scores In Predicting In-Hospital Mortality Among Adult Critical Care Patients With Suspected Infection, Mohammed A. Said, Wangari Siika, Vitalis Mung’Ayi, Reena Shah

Internal Medicine, East Africa

Introduction: Sepsis is global health priority and the leading cause of death in critical care. The SEPSIS 3 criteria introduced in 2016 is the latest tool in diagnosing sepsis. It uses SOFA and qSOFA scores in place of the SIRS criteria for better ability to predict mortality in patients with suspected infections. The performance of these scores in critical care units outside high-income countries remains largely unknown.

Methods: We compared the performance of SOFA and qSOFA in predicting the in-hospital mortality of an adult critical care unit in Kenya. We conducted a retrospective review of all patients admitted …

Kirplani, Laila Tul Qadar, Rohan Kumar Ochani, Zahid Ali Memon, Syeda Anjala Tahir, Khalid Imran, Naresh Kumar Seetlani, Amanullah Abbasi, Mahaish Kumar, Piyar Ali

Section of Internal Medicine

Introduction Spontaneous bacterial peritonitis (SBP) is the most common life-threatening infection in patients with ascites due to liver cirrhosis. The infection is most commonly caused by the bacterium Escherichia coli, commonly referred to as E. coli. Over the past few years, the incidence of antimicrobial resistance against E. coli has risen drastically, leading to increased morbidity and mortality. Methods This cross-sectional study was conducted to determine the pattern of resistance using variations of antibiotics against E. coli, to prevent its empirical usage and initiate an appropriate target antibiotic therapy. The data were collected from May 2017 to October 2017 and …

Bioaerosols Associated With Evaporative Cooler Use In Low-Income Homes In Semi-Arid Climates, Ashlin Elaine Cowger

Theses and Dissertations

Asthma is the leading chronic illness in children in the United States. Since children in the U.S. spend a majority of their time indoors there is an increased need to understand key sources of daily asthma triggers in the home. Bacterial endotoxin, dust mite allergens and β-D-glucan have been shown to be potent inducers of asthma attacks, and high levels of these allergens in homes can trigger attacks in those with asthma. We aim to better understand the risks to those with asthma that might be associated with evaporative cooler (EC) use in low-income homes. ECs are often promoted because …

Quantitative Systems Pharmacology Model Of Chimeric Antigen Receptor T-Cell Therapy, Deni Hardiansyah, Chee Meng Ng

Pharmaceutical Sciences Faculty Publications

Chimeric antigen receptor T‐cell (CART) therapy is a new and promising cancer therapy. However, severe toxicity due to cytokine release syndrome (CRS) in CART‐treated patients highlighted the possible danger of this new therapy. Disease burden and CART doses are the potential factors associated with CRS but the detail relationships between these factors and the severity of the CRS remain largely unknown. In this study, the quantitative systems pharmacology (QSP) approach is used to quantify the complex relationships among CART doses, disease burden, and pro inflammatory cytokines in human subjects and to gain relevant insights into the determinant of clinical toxicity/efficacy …

Background

TLR9 agonists are being developed as immunotherapy against malignancies and infections. TLR9 is primarily expressed in B cells and plasmacytoid dendritic cells (pDCs). TLR9 signalling may be critically important for B cell activity in lymph nodes but little is known about the in vivo impact of TLR9 agonism on human lymph node B cells. As a pre-defined sub-study within our clinical trial investigating TLR9 agonist MGN1703 (lefitolimod) treatment in the context of developing HIV cure strategies (NCT02443935), we assessed TLR9 agonist-mediated effects in lymph nodes.

Methods

Participants received MGN1703 for 24 weeks concurrent with antiretroviral therapy. Seven …

Patterns Of Polysubstance Use Among Those With Tranquilizer Or Sedative Misuse: Predictors And Functional Consequences, Victoria R. Votaw

Psychology ETDs

The misuse of tranquilizer and sedative medications (i.e., use without a prescription or at higher doses/longer periods of time than prescribed) is associated with myriad negative sequalae, such as suicidal behaviors and increased risk of overdose. Yet, prescription tranquilizer and sedative misuse has been largely overlooked by the scientific community, clinicians, and policymakers. We addressed this gap in the literature by characterizing subgroups of individuals with tranquilizer or sedative misuse, based on their patterns of polysubstance use. The present study analyzed data from two samples of individuals with past-month tranquilizer or sedative misuse: respondents of a nationally-representative household survey (general …

Evidence-Based Cardiac Monitoring: A Practice Change, Joseph Paul Urbanski

Doctoral Projects

Background: Overuse of cardiac monitoring (CM) in acute care settings contributes to increased healthcare spending and cost of services for patients. Additionally, inappropriate use of CM can contribute to wastefulness of healthcare resources, increases in hospital staff workloads, and can be improved with best evidence-based practice recommendations. A Midwest acute care hospital lacked an evidence-based, systematic method to define care for patients requiring CM.

Objective: The purpose of the project was to pilot an evidence-based CM change initiative, determine feasibility for sustainment, and propose next steps for adoption of the change initiative across non-emergency department, non-intensive care inpatient CM units …
