Prescription For Change: Tackling Inappropriate Antibiotic Use In Urgent Care Settings, Lachundra Mosley

Doctoral Projects

A pressing global health issue that significantly contributes to antibiotic resistance is the inappropriate antibiotic prescribing for Upper Respiratory Infections (URI’s) in urgent care settings (World Health Organization [WHO], 2022). The purpose of this doctoral project was to reduce inappropriate antibiotic prescriptions for URI at an urgent care in D’Iberville, Mississippi through the implementation of an educational pamphlet.

A pre-post intervention project was conducted, collecting data on antibiotic prescribing practices via retrospective chart reviews before and after the educational intervention. Data was collected using a researcher developed screening tool based on Evidence based guidelines to distinguish viral vs bacterial infections. …

The Mongolian Remodeling And The Structure Of Anoplocephalid Cestode Diversity, Mackenzie Grover

All NMU Master's Theses

Ecological disruption plays an important role in structuring diversity of flora, fauna, and their parasites. At the end of the Eocene, climatic change across Asia resulted in a faunal turnover (the Mongolian Remodeling) as rodents diversified and larger mammals declined. Throughout the Oligocene, the landscape in Asia was characterized by episodic climatic and landscape changes resulting in pulses of rodent diversification. The role of historical ecological disruption in Central Asia in structuring the diversity of parasites of small rodents has not been thoroughly investigated. The hyper-diverse Paranoplocephala species complex (family: Anoplocephalidae) infect rodents throughout the Holarctic and present an opportunity …

Estimating Medium-Term Regional Monthly Economic Activity Reductions During The Covid-19 Pandemic Using Nighttime Light Data, Ma Flordeliza P. Del Castillo, Toshio Fujimi, Hirokazu Tatano

SOSE Affiliate: Manila Observatory

Economic impact estimates of the initial lockdowns due to the COVID-19 pandemic showed a significant reduction in economic activities globally. However, the succeeding impacts and their spatiotemporal distribution within countries remain unknown. Studies showed that nighttime light data (NTL) has effectively revealed the spatiotemporal dimensions of the economic effects of COVID-19. Thus, this study used NTL data to determine the medium-term regional monthly economic impacts of the pandemic in the Philippines in terms of the Economic Activity Reduction (EAR) index. We generated a spatial error model, regressing pre-pandemic NTL on mean temperature, maximum rainfall, and built-up area. This model explained …

Dissecting Metabolic Landscape Of Alveolar Macrophage, Sunayana Malla

Department of Chemical and Biomolecular Engineering: Dissertations, Theses, and Student Research

The highly plastic nature of alveolar macrophage (AM) plays a crucial role in the defense against inhaled particulates and pathogens in the lungs. Depending on the signal, AM acquires either the classically activated M1 phenotype or the alternatively activated M2 phenotype. In this study, we investigate the metabolic shift in the activated phases of AM (M1 and M2 phases) by reconstructing context specific genome-scale metabolic (GSM) models. Metabolic pathways such as pyruvate metabolism, arachidonic acid metabolism, chondroitin/heparan sulfate biosynthesis, and heparan sulfate degradation are found to be important driving forces in the development of the M1/M2 phenotypes. Additionally, we formulated …

Proteolytic Manipulation Of Neutrophil Responses And The Efferocytic Synapse By Porphyromonas Gingivalis., Kelley N. Cooper

Electronic Theses and Dissertations

Porphyromonas gingivalis (Pg) is etiologically associated with chronic periodontitis, a highly prevalent chronic inflammatory disease characterized by the destruction of hard and soft tissues of the periodontium. Pg is adapted to live in the human oral subgingival niche, a hostile environment dominated by excessive numbers of activated neutrophils and antimicrobial mediators. Its survival is contingent upon prompt and effective inactivation of neutrophil effector functions. In this dissertation, I uncover a novel pathogenic mechanism employed by Pg that disarms the antimicrobial capacity of live neutrophils and simultaneously sequesters them within macrophages. Mechanistically, RgpB, a cysteine protease produced by Pg …

Differential Responses Of Human Neutrophils To Legionella Species., Hannah E. Hanford

Electronic Theses and Dissertations

Legionella species are Gram-negative facultative intracellular bacterial pathogens commonly found in freshwater or soil environments where they survive and replicate within their natural protozoan hosts. Humans serve as an accidental host for Legionella species after inhalation of contaminated aerosolized water droplets or soil particles enabling the bacteria to enter the lungs, infect alveolar macrophages, and result in severe pneumonia. Evasion of degradation and proliferation within alveolar macrophages by Legionella species and manifestation of “Legionnaires’ disease” is dependent on the Dot/Icm type IV secretion system (T4SS). The T4SS apparatus is a needle-like channel for translocation of over ~350 effector proteins, depending …

Plasma Resuscitation Attenuates Hemorrhage-Induced Glomerular Barrier Damage And Dysfunction., William Byron Risinger

Electronic Theses and Dissertations

Introduction: Acute renal dysfunction following traumatic injury and hemorrhagic shock carries significant morbidity and mortality. Despite an extensive understanding of renal tubule damage after injury, less is known regarding early alterations to the glomerular filtration barrier following hemorrhagic shock and resuscitation. Previously, our lab and others have demonstrated improved hepatic and intestinal microcirculatory parameters when resuscitation strategies incorporate fresh frozen plasma. In addition to improving end-organ perfusion, plasma reconstitutes the endothelial glycocalyx, an essential regulator of vascular permeability and microcirculatory function. However, the impact of plasma resuscitation on the glomerular glycocalyx and barrier following hemorrhage remains unknown. We hypothesized …

Citation Bias, Diversity, And Ethics, Keisha S Ray, Perry Zurn, Jordan D Dworkin, Dani S Bassett, David B Resnik

Faculty and Staff Publications

How often a researcher is cited usually plays a decisive role in that person's career advancement, because academic institutions often use citation metrics, either explicitly or implicitly, to estimate research impact and productivity. Research has shown, however, that citation patterns and practices are affected by various biases, including the prestige of the authors being cited and their gender, race, and nationality, whether self-attested or perceived. Some commentators have proposed that researchers can address biases related to social identity or position by including a Citation Diversity Statement in a manuscript submitted for publication. A Citation Diversity Statement is a paragraph placed …

Synthesis Of Novel Chromenone Esters For Biochemical Assays, Andrew Dean Helmerich

Undergraduate Honors Thesis Collection

This project details the synthesis of a variety of novel chromenone esters to be used as enzymatic probes. A robust, initial library of 22 chromenone esters was successfully synthesized with differences in chain length, branching, and the incorporation of cyclic and heteroatomic moieties. These new chromenones were fully characterized by 1HNMR, 13CNMR, DEPT HRMS, 19FNMR, and HSQC. The utility of these compounds comes from the fact that they will fluoresce upon cleavage of the ester; thus, this property makes them ideal candidates to be used in the monitoring of enzymatic activity of esterases. Elucidating the enzyme-substrate structure activity relationship (SAR) …

Institute for Human Development, East Africa

The complex dynamics of protein expression in plasma during hyperacute HIV-1 infection and its relation to acute retroviral syndrome, viral control, and disease progression are largely unknown. Here, we quantify 1293 blood plasma proteins from 157 longitudinally linked plasma samples collected before, during, and after hyperacute HIV-1 infection of 54 participants from four sub-Saharan African countries. Six distinct longitudinal expression profiles are identified, of which four demonstrate a consistent decrease in protein levels following HIV-1 infection. Proteins involved in inflammatory responses, immune regulation, and cell motility are significantly altered during the transition from pre-infection to one month post-infection. Specifically, decreased …

Stepping Back: Evaluating Antipseudomonal Antibiotic Use In Diabetic Foot Infection., Hannah Davis Pharmd, Michele Walters Pharmd, Bcps, Aq-Id, Sarah Ferrell Pharmd, Bcpps, Jui Patel Pharmd, Bcps, Tiffany O'Keefe Pharmd, Bcgp

Pharmacy Residency

Presented at the ASHP Midyear Clinical Meeting. New Orleans, LA

This study found that anti-pseudomonal (PsA) coverage is overutilized in diabetic foot infection (DFI), even when broad qualifying criteria are applied. The proposed criteria were poor predictors of PsA growth, which was present in a small number of cases. Patients who did grow PsA were somewhat more likely to have severe DFI, history of DFI, and 90-day history of admission or anti-PsA antibiotic use, but many patients without PsA growth also met these criteria.

Use Of Equine H3n8 Hemagglutinin As A Broadly Protective Influenza Vaccine Immunogen, David Verhoeven, Brett A. Sponseller, James E. Crowe, Sandhya Bangaru, Richard J. Webby, Brian M. Lee

Chemistry

Development of an efficacious universal influenza vaccines remains a long-sought goal. Current vaccines have shortfalls such as mid/low efficacy and needing yearly strain revisions to account for viral drift/shift. Horses undergo bi-annual vaccines for the H3N8 equine influenza virus, and surveillance of sera from vaccinees demonstrated very broad reactivity and neutralization to many influenza strains. Subsequently, vaccinating mice using the equine A/Kentucky/1/1991 strain or recombinant hemagglutinin (HA) induced similar broadly reactive and neutralizing antibodies to seasonal and high pathogenicity avian influenza strains. Challenge of vaccinated mice protected from lethal virus challenges across H1N1 and H3N2 strains. This protection correlated with …
