Examining The Association Between Smoking Frequency And Long Covid: A Brfss Study, Bhavya Patel

Capstone Experience

Objectives: To examine the relationship between self-reported smoking frequency and the presence of Long COVID among individuals who tested positive for COVID-19.

Methods: A cross-sectional study was conducted using a sample of 44,738 COVID-positive participants from the 2022 Behavioral Risk Factor Surveillance System (BRFSS) dataset. Logistic regression was utilised to compute prevalence odds ratios (pOR) and was adjusted for potential sociodemographic confounders.

Results: Individuals who smoked daily were found to have a greater likelihood of reporting Long COVID in comparison with nonsmokers (Crude pOR=1.22; CI= [1.10-1.35]). However, in the adjusted regression model, daily smoking was no longer significant (Adjusted pOR=1.04; …

Structure And Function Of Long-Covid Evaluated Using Pulmonary Imaging, Harkiran Kaur Kooner

Electronic Thesis and Dissertation Repository

The COVID-19 pandemic has resulted in millions of global respiratory infections, ranging in severity from asymptomatic to fatal. One of the many consequences of the pandemic is the emergence of long-COVID, which is an umbrella term used to describe the long-term sequelae and poor quality-of-life following recovery from acute COVID-19 infection. However, the pathophysiology and mechanisms responsible for the heterogenous manifestation of long-COVID remain poorly understood. Hyperpolarized ¹²⁹Xe magnetic resonance imaging (MRI) provides a non-invasive and radiation-free method to regionally visualize and quantify inhaled gas distribution and ventilation in vivo. A strong foundation for the use of pulmonary …

Comparison Of Covid-19 Diagnostic Testing Methodologies In The U.S., Joseph Blommel

All Dissertations

The onset of the COVID-19 pandemic brought about a world in which diagnostic testing for the virus that is responsible for COVID-19, SARS-CoV-2, became commonplace. Diagnostic testing was required for myriad reasons beyond simple diagnosis. We set out to compare SARS-CoV-2 testing methods, see if differences sensitivity correlated to increased positivity, and to evaluate self-collection methods.

In examining the Limit of Detection (LoD) of tests receiving FDA Emergency Use Authorization (EUA), our findings indicated that there were considerable differences in LoD. However, these differences in observed sensitivity were not correlated with the methodologic differences as reported in EUA documentation.

We …

Generation Of Chimeric Rhinoviruses Presenting Sars-Cov-2 Broadly Neutralizing Epitopes And Their Antigenicity Characterization, Danish Ansari

Biotechnology Theses

The global COVID pandemic is not yet fully under control as there were over 21 million new cases of SARS-CoV-2 infections and over 50,000 deaths globally as of January of 2022. A heavily mutated variant of concern, Omicron is responsible for most of these cases which demands an urgency for a new vaccine. NIH reports over 180 vaccine candidates that use various strategies currently in development. However, a recurring concern with these vaccines is that the continuous viral mutations decrease the efficacy of vaccines. Therefore, we proposed to construct a human rhinovirus (HRV) based chimeric virus containing highly conserved, broadly …

Protein S In Coagulation And Inflammation, Martha Mega Silvia Sim

Theses and Dissertations--Molecular and Cellular Biochemistry

Protein S (PS) is a key regulator, which links inflammation and coagulation and performs multiple proposed functions in both processes. PS exists in the blood as a free soluble form (~40%), bound to complement component 4b-binding protein/ C4BP (~60%), and packaged in platelet α-granules (~2.5%). Subendothelial tissue factor (TF), upon exposure to blood, initiates coagulation, a proteolytic cascade which results in the activation of thrombin, the enzyme responsible for formation of a fibrin clot. PS is a critical anticoagulant that inhibits multiple steps of this process. Only the free fraction of PS has full anticoagulant properties, as C4BP blocks this …

Chronic Hiv Infection Influences The Immune Response To Sars-Cov-2, Skye Opsteen

All ETDs from UAB

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused global morbidity and mortality since late 2019. Many infections result in self-limited disease and recovery in 1-2 weeks. However, a subset of individuals experience more severe illness, associated with hospitalization, ventilation, and potential mortality. HIV infection is a proposed risk factor for more severe illness due to people living with HIV (PLWH) experiencing chronic immune activation and inflammation despite effective antiretroviral therapy. While there is supporting evidence showing worsened clinical outcomes in PLWH experiencing acute COVID-19, the immune response driving these outcomes is less explored. We analyzed markers of immune activation …

Master of Science in Nursing Final Projects

Introduction: In March 2020, the novel coronavirus originating out of Wuhan in China and spreading rapidly worldwide, became known as the COVID-19 pandemic. Patients with pre-existing conditions, such as the elderly and pregnant women, are among those most vulnerable to severe infection due to COVID-19. Increased pulmonary expansion in the respiratory tract make pregnant women more susceptible to viral respiratory infections and exacerbation of illnesses like COVID-19. Another major concern correlated with the pandemic and pregnancy is its effect on pregnant women’s mental health. Unique physiological and psychological changes place pregnant women at an increased risk for experiencing mental health …

Regulation Of Mhc Ii Trafficking And Expression By Host And Viral Factors, Alex Lac

Electronic Thesis and Dissertation Repository

Antigen presentation by major histocompatibility complex class II (MHC II) to the adaptive immune system is crucial for mounting sterilizing immune responses. This central role has made antigen presentation a target for antagonism by many pathogens. Notably, infections with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) decrease MHC II expression in several immune cells. The mechanisms responsible for this suppression are unknown but involves either redirecting MHC II molecules away from the cell surface or inhibiting MHC II expression. To understand how pathogens manipulate intracellular MHC II trafficking, we first investigated the role of the Golgi trafficking regulator, ERC1, in …

In December 2019, the World Health Organization (WHO) was informed of an outbreak of an unknown cause of pneumonia-like symptoms in residents concentrated in Wuhan, China; this marked the start of China’s epidemic, which transformed into a pandemic affecting all continents of the world. The cause of the pneumonia-like symptoms was found to be due to the growth and development of the virus severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) which spreads through an infected person’s respiratory droplets through activities such as talking, coughing, and sneezing. With COVID-19 vaccine manufacturers available worldwide, even the economically and technologically forward countries …

Reducing Central Line-Associated Bloodstream Infections At A Rural Midwestern Hospital Through An Evidence-Based Nurse-Led Practice Change Intervention, Crystal B. Lavalley

DNP Scholarly Projects

Central line-associated bloodstream infections (CLABSIs) are responsible for increased patient morbidity, mortality, and healthcare costs, despite being a preventable harm (Barnes et al., 2015; Furuya et al., 2016). Evidence-based (EB) research suggests that the use of central line bundles is the most effective way to reduce CLABSIs in hospitals (Barnes et al., 2015; Furuya et al., 2016). Researchers have also found a statistically significant correlation between nurse compliance with bundle components and CLABSI rates (Aloush & Alsaraireh, 2018; Furuya et al., 2016). The purpose of this study was to determine if a nurse-led collaborative that focused on CLABSI reduction using …

Wastewater Surveillance Of Sars-Cov-2 On American University Campuses: A Comparison Of Responses To The Covid-19 Pandemic, Emily Gosnell

Senior Theses

Wastewater surveillance has been used for a variety of purposes but, in recent years, has most notably been utilized during the COVID-19 pandemic. Many universities in the United States used it as a means of monitoring levels of the SARS-CoV-2 virus on their campuses. The University of South Carolina, University of Arizona, and University of North Carolina- Charlotte were three such schools. An analysis of data published by these three schools has been used to synthesize a proposed list of best methods to be used by other universities during the reemergence of SARS-CoV-2 or during the outbreak of a new …

Characteristics Of Covid-19 Vaccine-Hesitant Ucf College Students And Potential Avenues For Increasing Vaccination Rates, Justin A. Barthel

Honors Undergraduate Theses

The COVID-19 pandemic has been an ongoing disaster that has devasted millions of lives. With the development of COVID-19 vaccines in late 2020, there was a potential for populations to gain artificial active immunity in order to prevent future outbreaks. However, despite successful clinical trials, millions of citizens have been hesitant to receive the COVID-19 vaccines (Khubchandani et al., 2021). Demographics of the most prominent US vaccine-hesitant populations consist of ethnic/racial minorities and Republicans groups (Khubchandani et al., 2021). Little information is known about COVID-19 vaccine hesitancy in colleges and universities. Colleges provide an elevated risk for infection through their …

Evaluation Of Interactions Of Covid Nonstructural Proteins 3, 5, And 6 With Human Proteins And Potentially Therapeutic Molecules, Jessica Huitsing

Honors Undergraduate Theses

The COVID-19 pandemic, caused by Severe Acute Respiratory Syndrome Coronavirus 2, or SARS-CoV-2, has been ongoing for over two years. The virus spreads easily and is more unpredictable than well-known viruses like the flu, making it important to have reliable combative measures before we fully drop non-vaccine preventive actions, like mask-wearing.Therefore, we used computational protein modeling to investigate the interactions of three nonstructural proteins (abbreviated Nsp) encoded in the viral RNA genome– Nsp3, Nsp5, and Nsp6 – which are involved in the viral life cycle, with human P-type polyamine transporting ATPases ATP13A2 and ATP13A3, whose disease symptoms when mutated mimic …

Utilizing The K18-Hace2 Mouse Model To Develop Protective Covid-19 Vaccines, Ting Y. Wong

Graduate Theses, Dissertations, and Problem Reports

The ongoing Coronavirus Disease 2019 (COVID-19) pandemic is caused by the respiratory virus Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). Similar to other respiratory viruses, SARS-CoV-2 is transmitted through inhalation of respiratory droplets and aerosols from infected individuals. Once inhaled, SARS-CoV-2 utilizes the receptor binding domain (RBD) on the spike protein to bind to human Angiotensin Converting Enzyme 2 (hACE2) receptor to gain entrance into host cells to begin viral replication. SARS-CoV-2 infection can result in mild to severe cases of COVID-19 ranging from asymptomatic infections, cold or flu like symptoms to respiratory failure. The onset of the pandemic in …

A Serological Analysis Of Sars-Cov-2 Infection In The Obstetric Population, Sophia Rose

CMC Senior Theses

In December 2019, the surfacing and spread of a novel coronavirus, SARS-CoV-2, resulted in the global COVID-19 pandemic. As a viral antigen, SARS-CoV-2 poses a particular threat to the obstetric population due to physiological and immunological changes that women face during pregnancy. While recent studies have found that SARS-CoV-2 may have better clinical outcomes as compared to other betacoronaviruses, adverse pregnancy events such as ICU admission, preeclampsia, and/or preterm birth have been associated with COVID-19. Progress has been made in better understanding the pathophysiology of SARS-CoV-2 in pregnancy, but there is still much to be known about the interaction …

Determining The Impact Of Immune Dysregulation On Cd4 T Cell Responses To Hiv-1 And Sars-Cov-2, Jacob K. Files

All ETDs from UAB

CD4+ T cells, often referred to as helper T cells, play a crucial role in the formation of antiviral immune responses following infection and vaccination. However, this can be disrupted by various forms of immune dysregulation. Many groups have described how HIV-1 adaptation and immune escape can lead to dysregulated HIV-specific immune responses. Our lab has previously shown that predicted HLA-II associated HIV-1 adaptation leads to dysregulated, poorly immunogenic CD4+ T cell responses in HIV-1 infection. Here, we focus on the impact of this HLA-II associated viral adaptation in the setting of HIV-1 vaccination. We show that HLA-II associated, vaccine-matched …

The Efficacy Of Tocilizumab As A Therapeutic Treatment For Sars-Cov-2 Infections: An Integrative Literature Review, Amanda Vancene Peterson

Nursing Masters Papers

The novel coronavirus SARS-CoV-2 and resulting COVID-19 infection has spread from a cluster of unidentified pneumonia cases in Wuhan, China, into an ongoing global health crisis. The strain on the healthcare systems and loss of human life has made finding ways to treat severe COVID-19 infections of the utmost importance. Mortality from COVID-19 has been shown to result from an overwhelming inflammatory response similar to the cytokine release syndrome seen in certain autoimmune reactions (Tleyjeh et al., 2020). It also can be seen after chimeric antigen receptor T-cell (CAR-T) therapy for certain cancers. It is hypothesized that treatments targeting the …

Advancing Rna Virus Discovery And Biology With Whole Genome Sequencing, Mariah Katherine Taylor

Theses and Dissertations (ETD)

Two RNA virus families that pose a threat to human and animal health are Hantaviridae and Coronaviridae. These RNA viruses which originate in wildlife continue and will continue to cause disease, and hence, it is critical that scientific research define the mechanisms as to how these viruses spillover and adapt to new hosts to become endemic. One gap in our ability to define these mechanisms is the lack of whole genome sequences for many of these viruses. To address this specific gap, I developed a versatile amplicon-based whole-genome sequencing (WGS) approach to identify viral genomes of hantaviruses and severe acute …

Theses and Dissertations

The pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in 2020 has impacted daily life globally for over a year. While multiple vaccines have been authorized for emergency use and one oral medication has entered clinical trials, we are still seeking antiviral drugs for a long-term treatment for SARS-CoV-2 as well as other coronaviruses. Computational drug screenings of two SARS-CoV-2 protein target candidates are presented in this thesis: the nidoviral RNA uridylate-specific endoribonuclease (Nsp15) and the main protease (Mpro) of SARS-CoV-2. Nonstructural proteins of coronaviruses were selected as targets as they are more conserved across coronavirus strains than …

Cardiovascular Disease Risk In Young Adults Following Covid-19, Andrew Heckel

Theses - ALL

Introduction: SARS-CoV-2, the virus responsible for COVID-19, may cause a dysregulated systemic inflammatory response that could lead to cardiovascular damage and cause individuals recovering from COVID-19 to be at an increased risk for future cardiovascular disease (CVD). Physical activity (PA) is inversely associated with systemic inflammation and CVD risk, which may make it a useful cardioprotective lifestyle factor for individuals recovering from COVID-19. Purpose: 1) Compare arterial stiffness and systemic inflammatory levels between individuals recovering from COVID-19 and uninfected controls, 2) explore systemic inflammation as a predictor of arterial stiffness, and 3) explore PA as a mediator for the relationship …

Roles Of A Bradykinin Storm And A Cytokine Storm In Covid-19 Cases, Nouha H. Odeh

Honors College Theses

In the light of recent events, it is imperative to understand the key inflammatory response elements that appear to be the source of more severe ailments resulting from a SARS-CoV-2 viral infection known as Covid-19 The more severe cases of Covid-19 are characterized by a severe inflammatory response resulting in tissue damage. My research proposal aims to investigate the two possible culprits of this response: a bradykinin (BK) storm and an interleukin-6 (IL-6) mediated cytokine storm. In both systems respectively, the excess release of these signals subsequently signals the production of even more of the same response element, resulting in …
