Online News Portrayal During The Covid-19 Health Crisis And Journalism's Role In Misinformation In The U.S., Michou Ducilon Oct 2023

Online News Portrayal During The Covid-19 Health Crisis And Journalism's Role In Misinformation In The U.S., Michou Ducilon

USF Tampa Graduate Theses and Dissertations

The COVID-19 pandemic has brought a wealth of new information regarding the virus's origin and treatment. Regrettably, the vast amount of online information has resulted in the proliferation of misinformation, as the World Health Organization reported. To investigate whether journalists may have contributed to this problem, a qualitative analysis was conducted on 15 news articles from top-tier media outlets. Using NVivo software, the articles were analyzed to identify linguistic words and visuals that fell into coding categories based on Behrendt's (2008) contextual analysis for evaluating text. Each article was then coded again to identify common themes. During this process, new …

An Investigation Of Mitigation Measures On The Spread Of Covid-19 In A College Classroom Using Agent-Based Modeling, Saharsh Talwar, Anne E. Yust Oct 2023

An Investigation Of Mitigation Measures On The Spread Of Covid-19 In A College Classroom Using Agent-Based Modeling, Saharsh Talwar, Anne E. Yust

Spora: A Journal of Biomathematics

In this manuscript, we describe the process of using agent-based modeling in NetLogo to create a simulation of COVID-19 spread in a traditional college classroom. The model allows for an evaluation of different preventative measures implemented by the University of Pittsburgh, including the cohort classroom attendance model, mask and vaccine mandates, contact tracing, and classroom sanitation. Through the use of the model's interactive interface, the impact of adjusting specific measures by the institution could be visualized, providing a valuable tool for combating diseases that spread through droplet transmission.

Post-infectious conditions present major health burdens but remain poorly understood. In Chagas disease (CD), caused by Trypanosoma cruzi parasites, antiparasitic agents that successfully clear T. cruzi do not always improve clinical outcomes. In this study, we reveal differential small molecule trajectories between cardiac regions during chronic T. cruzi infection, matching with characteristic CD apical aneurysm sites. Incomplete, region-specific, cardiac small molecule restoration is observed in animals treated with the antiparasitic benznidazole. In contrast, superior restoration of the cardiac small molecule profile is observed for a combination treatment of reduced-dose benznidazole plus an immunotherapy, even with less parasite burden reduction. Overall, …

Identification Of Chronic Wasting Disease Prions In Decaying Tongue Tissues From Exhumed White-Tailed Deer, Paulina Soto, Francisca Bravo-Risi, Rebeca Benavente, Stuart Lichtenberg, Mitch Lockwood, J Hunter Reed, Rodrigo Morales

Faculty, Staff and Student Publications

Chronic wasting disease (CWD) prions cause fatal neuropathies in farmed and free-ranging cervids. The deposition of prions in natural and humanmade environmental components has been implicated as a major mechanism mediating CWD spread in wild and captive populations. Prions can be deposited in the environment through excreta, tissues, and carcasses from pre-clinical and clinical animals. Furthermore, burial of CWD-positive animals may reduce but not completely mitigate prion spread from carcasses into the surrounding environment. Here, we analyzed exhumed, decaying deer carcasses for the presence of CWD prions. By analyzing tongue tissues through the protein misfolding cyclic amplification (PMCA) technique, we …

Co-infection with Streptococcus mutans and Candida albicans is associated with dental caries, and their co-cultivation results in enhanced biofilm matrix production that contributes to increased virulence and caries risk. Moreover, the catalase-negative S. mutans demonstrates increased oxidative stress tolerance when co-cultivated in biofilms with C. albicans, a catalase-producing yeast. Here, we sought to obtain mechanistic insights into the increased H2O2 tolerance of S. mutans when co-cultivated with clinical isolates of Candida glabrata, Candida tropicalis, and C. albicans. Additionally, the C. albicans SC5314 laboratory strain, its catalase mutant (SC5314Δcat1), and S. mutans UA159 and its glucosyltransferase B/C …

Background

Infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) produces the coronavirus disease of 2019 (COVID-19), primarily presenting with respiratory symptoms, including cough, shortness of breath, etc. Respiratory failure can present similarly to a COVID-19 infection, and COVID-19 infection can cause respiratory failure. Thus, it is important to study respiratory failure, COVID-19, and the interaction between the two in hopes of improving patient outcomes. In this study, we compared mortality rates in patients admitted with COVID-19, respiratory failure, or both. Mortality rates in our study populations were further scrutinized based on patient age.

Sore throat is one of the most common complaints encountered in the ambulatory clinical setting. Rapid, culture-independent diagnostic techniques that do not rely on pharyngeal swabs would be highly valuable as a point-of-care strategy to guide outpatient antibiotic treatment. Despite the promise of this approach, efforts to detect volatiles during oropharyngeal infection have yet been limited. In our research study, we sought to evaluate for specific bacterial volatile organic compounds (VOC) biomarkers in isolated cultures

Law’S Sexual Infections, Kyle Kirkup Oct 2023

Law’S Sexual Infections, Kyle Kirkup

Dalhousie Law Journal

In 2019, the House of Commons Standing Committee on Justice and Human Rights published its study on the criminalization of HIV non-disclosure in Canada. The report recommended removing HIV non-disclosure from sexual assault laws in Canada. This constituted a welcome development for many HIV advocates. Yet other recommendations proved more controversial. In order to counter the exceptional targeting of HIV, the Committee proposed an offence for the non disclosure of all infectious diseases. This article uses the proposal to develop three arguments. First, the idea of creating an offence for all infectious diseases finds its origins in criminal laws dating …

School of Medicine Publications

Older people are at high risk of developing and dying from pulmonary infections like tuberculosis (TB), but there are few studies among them, particularly in Hispanics. To address these gaps, we sought to identify host factors associated with TB and adverse treatment outcomes in older Hispanics by conducting a cross-sectional study of TB surveillance data from Tamaulipas, Mexico (2006–2013; n = 8381). Multivariable logistic regressions were assessed for older adults (OA ≥65 years) when compared to young (YA, 18–39 years) and middle-aged adults (40–64 years). We found that the OA had features associated with a less complicated TB (e.g., lower …

Dynamic Analysis Of Rumor Spreading Models In Social Networks With Time Delay, Y. M. R. Marbun, T. Tulus, S. Sutarman, E. Herawati

Information Sciences Letters

The spread of rumors is essential to social interaction, significantly affecting work and daily life. In terms of transmission, rumors are similar to diseases, so a mathematical model of rumors can be constructed using the epidemic model. This study aims to develop and analyze a mathematical model for spreading rumors in the form of S, I, and R compartments. The experimental method is used by adding a delay time where the acceptance rate is constant. The analysis obtained two equilibrium points: the rumor-free equilibrium point and the rumor-endemic equilibrium point. The rumor-free equilibrium point will be asymptotically stable when R0 …

USF Tampa Graduate Theses and Dissertations

Parkinson’s disease (PD) is the second most common neurodegenerative disease after Alzheimer’s disease and the fastest-growing neurodegenerative disorder in the world. The major issue with PD is that it takes several years of biological changes until the patient starts to experience physiological symptoms that could affect their daily lives. The major hallmark of PD is the appearance of Lewy body inclusions in the neuron’s cytoplasm, which is rich in a protein called α-Synuclein (α-Syn). Several studies have shown that the levels of α-Syn in blood increase because the excess α-Syn is released from neurons into the bloodstream through extracellular vesicles. …

Kaposi sarcoma (KS), a multifocal vascular neoplasm frequently observed in HIVpositive individuals, primarily affects the skin, mucous membranes, visceral organs, and lymph nodes. KS is associated primarily with Kaposi sarcomaassociated herpesvirus (KSHV) infection. In this case report, we present a rare occurrence of co-infection and co-localization of KSHV and Epstein-Barr virus (EBV) in KS arising from the conjunctiva, which, to our knowledge, has not been reported previously. Immunohistochemistry (IHC), DNA polymerase chain reaction (PCR), and EBV-encoded RNA in situ hybridization (EBER-ISH) were utilized to demonstrate the presence of KSHV and EBV infection in the ocular KS lesion. Nearly all KSHV-positive …


Clinically Applied Anthropology: A Syndemic Intervention., Jason W. Wilson Oct 2023

Clinically Applied Anthropology: A Syndemic Intervention., Jason W. Wilson

USF Tampa Graduate Theses and Dissertations

This dissertation demonstrates that a critical, clinically applied anthropology is possible by testing a hypothesis that a syndemic intervention, and use of a structural vulnerability assessment tool, can achieve improved healthcare outcomes. A critical, clinically applied anthropology integrates social scientists into healthcare delivery, alongside biomedical providers, through the co-creation of new diagnostic and patient care pathways that utilize anthropological methods (ethnographically informed care, syndemics, thematic/mixed methods data analysis) and advance anthropological theory (biomedicine and culture, structural violence, structural competency/vulnerability, ontology, assemblage theory, and entanglements) to decrease healthcare inequities.

Medical anthropology has previously engaged biomedicine and other attempts at a clinical …

Antiviral Treatment Of Maternal And Congenital Cytomegalovirus (Cmv) Infections, Swetha Pinninti, Suresh Boppana

APC Fund

Human Cytomegalovirus (HCMV) is a ubiquitous member of the Herpesviridae family, responsible for the most common congenital viral infection—congenital Cytomegalovirus (cCMV) infection. While a majority of HCMV infections in children and adults are asymptomatic, HCMV is well known to cause severe infections in the immunocompromised individual and maternal infections with variable long-term sequelae after maternal–fetal transmission with primary or nonprimary infections. HCMV seroprevalence and cCMV incidence vary by geographic area and demographic characteristics like race and socioeconomic status. While cCMV birth prevalence ranges from 0.2% to 6% in different parts of the world, it is influenced by regional HCMV seroprevalence …

The recent success of mRNA therapeutics against pathogenic infections has increased interest in their use for other human diseases including cancer. However, the precise delivery of the genetic cargo to cells and tissues of interest remains challenging. Here, we show an adaptive strategy that enables the docking of different targeting ligands onto the surface of mRNA-loaded small extracellular vesicles (sEVs). This is achieved by using a microfluidic electroporation approach in which a combination of nano- and milli-second pulses produces large amounts of IFN-γ mRNA-loaded sEVs with CD64 overexpressed on their surface. The CD64 molecule serves as an adaptor to dock …

Mycobacterium tuberculosis drug resistance is emerging and new drug targets are needed. Tryptophan biosynthesis is necessary for M. tuberculosis replication and virulence. Indole-3-glycerol phosphate synthase (IGPS) catalyzes a step in M. tuberculosis tryptophan biosynthesis and has been suggested as a potential anti-infective target, but our understanding of this enzyme is limited. To aid in inhibitor design and gain a greater mechanistic picture of this enzyme, there is a need to understand the roles of active site amino acids in ligand binding and catalysis. In this work, we explored the roles of conserved active site amino acids Glu57, Lys59, Lys119, Glu168, …

A Fairness Assessment Of Mobility-Based Covid-19 Case Prediction Models, Abdolmajid Erfani, Vanessa Frias-Martinez Oct 2023

A Fairness Assessment Of Mobility-Based Covid-19 Case Prediction Models, Abdolmajid Erfani, Vanessa Frias-Martinez

Michigan Tech Publications

In light of the outbreak of COVID-19, analyzing and measuring human mobility has become increasingly important. A wide range of studies have explored spatiotemporal trends over time, examined associations with other variables, evaluated non-pharmacologic interventions (NPIs), and predicted or simulated COVID-19 spread using mobility data. Despite the benefits of publicly available mobility data, a key question remains unanswered: are models using mobility data performing equitably across demographic groups? We hypothesize that bias in the mobility data used to train the predictive models might lead to unfairly less accurate predictions for certain demographic groups. To test our hypothesis, we applied two …
