Objective: Analyze county level socioeconomic factors and their association with Covid-19 excess mortality in Alabama.Methods: Linear regression analyses were used to evaluate the association between potential risk factors assessed using the American Community survey (n = 40 counties and county clusters) and excess mortality in 2020 per 100,000 population. Excess mortality came from a previously published paper by Ackley et al. Results: Median household income (per 1,000 dollars); an average county median household income that 1,000 dollars higher was associated with 6 per 100,000 lower excess mortality (β= -5.953 p-value


Telehealth High-Intensity Interval Exercise And Cardiometabolic Health In Spinal Cord Injury, Jacob Adams Jan 2022

Telehealth High-Intensity Interval Exercise And Cardiometabolic Health In Spinal Cord Injury, Jacob Adams

All ETDs from UAB

BACKGROUND: Recent studies have shown that high intensity interval training (HIIT) can improve cardiometabolic health in individuals with spinal cord injury (SCI). Individuals with SCI experience a wide array of barriers to participate in exercise such as lack of time, accessible equipment, and transportation. It is imperative to identify modes of exercise that provide effective health benefits and are accessible while requiring low time commitment. Studies have demonstrated that HIIT has similar positive improvements in cardiometabolic health with 20% of total time commitment compared to moderate intensity exercise (MIT) in short term studies. OBJECTIVES: The purpose of this study is …

A Gastrointestinal-Specific Antibiotic As An Experimental Treatment For Anxio-Depressive Disorders, Yuang-Tai Huang

All ETDs from UAB

Chronic stress is a predisposing factor for various disease states, including neuropsychiatric disorders, such as depression and anxiety [1]. Stress-related disorders have complicated multifactorial etiologies [2]. Advances in psychotherapeutic and psychotropic treatments have occurred, but anxiety and depressive disorders are still prevalent and remain a burden to our societies [3]. More than 30% of major depressive disorder patients fail to remission despite an FDAapproved medication [4]. Meanwhile, the contribution of microbiota-gut-brain axis signaling in both etiologies and treatment of stress-related disorders is increasingly being recognized [5]. More evidence has shown that the gut microbiota has the potential to alter the …

"The Cloak Of Social Feeling": Alfred Adler's Gemeinschaftsgefuhl In Practice And Memory, Esteban T. Arnold Jan 2022

"The Cloak Of Social Feeling": Alfred Adler's Gemeinschaftsgefuhl In Practice And Memory, Esteban T. Arnold

All ETDs from UAB

This thesis provides a comprehensive overview of the evolution of Alfred Adler’s concept of Gemeinschaftsgefühl (community feeling), a simple yet potent idea that started in a Viennese café and expanded far beyond it. Ideas have lives beyond that of their authors, and this thesis argues that Alfred Adler’s idea of Gemeinschaftsgefühl was pressed into the service of various social and political agendas. Adler was privately a socialist, but he never wished to see Gemeinschaftsgefühl become a tool for this or any other movement. With an idealistic worldview, Adler sought to challenge and transform the pervading medical and psychotherapeutic conceptions of …


Adverse Childhood Experiences: Connecting The Dots Between Early Life Stress And Asthma Aming Children And Adolescents With Sickle Cell Disease, Brandi Mcclain Pernell Jan 2022

Adverse Childhood Experiences: Connecting The Dots Between Early Life Stress And Asthma Aming Children And Adolescents With Sickle Cell Disease, Brandi Mcclain Pernell

All ETDs from UAB

Sickle cell disease (SCD) is an inherited red blood cell disorder plagued by increased morbidity and premature mortality. Asthma disproportionally affects individuals with SCD and is strongly associated with an increased incidence of pain, acute lung complications and death among this high-risk population. Psychological stress is a well-established contributor and trigger for asthma development and exacerbations. Adverse Childhood Experiences (ACEs) are defined as traumatic experiences occurring before 18 years of age. ACEs occur at the individual, familial (Original-ACEs) and community level (Expanded-ACEs) and can accumulate with time. Chronic exposure to ACEs leads to toxic stress, widespread inflammation and risk for …

All ETDs from UAB

Transplant physicians review clinical data ranging from laboratory values to substance use history and use prediction models combining these factors, along with previous recipient outcomes, to evaluate deceased organ donors for organ suitability. Factors such as social determinants of health (SDOH) are not currently included in prediction models, despite evidence of relationships between SDOH and health outcomes in the general population. Occupational status is a SDOH routinely collected at the time of donation and stored in DonorNet, but not yet characterized in the deceased donor population. Despite well-documented relationships between occupational status and health outcomes in the general population, these …


Adolescent Alcohol, Tobacco, And Marijuana Use And Dma Methylation In Young Adulthood, Kristina Brooke Mcmahan Jan 2022

Adolescent Alcohol, Tobacco, And Marijuana Use And Dma Methylation In Young Adulthood, Kristina Brooke Mcmahan

All ETDs from UAB

Substance use, including the use of tobacco, alcohol, marijuana, and other drugs, is most likely to begin during adolescence or emerging adulthood. Substance use during these developmental periods has been linked with a number of negative physical, mental, and cognitive health outcomes. Some of these long-term negative effects of substance use during adolescence and emerging adulthood may be explained by epigenetic changes through a process called DNA methylation. However, much of the research on substance use and DNA methylation has focused on prenatal drug exposure and its relationship to differential methylation profiles during childhood and young adulthood. By contrast, little …

The Effects Of Near Field Magnetic Induction Monitoring Of Health Care Workers' Hand Hygiene Compliance, Thomas H. Ozburn

All ETDs from UAB

Hospital Acquired Infections (HAIs) are among the top five leading causes of death in the United States (Scott, 2009). Estimates of the annual direct medical costs of HAIs to U.S. hospitals have ranged from $28,400,000,000 to $33,800,000,000 (Scott, 2009). Many leading health care organizations have agreed that there is a link between infection prevention and the spread of HAIs (Allegranzi, 2009). This study explored health care workers’ hand hygiene compliance and whether automated compliance reporting improved compliance. A new system powered by technology called Near Field Magnetic Induction (NFMI) found a significant increase in compliance upon introduction of an automated …

The Effects Of Charity Hospital Privitization And Medicaid Expansion On Medicaid Patient Emergency Department Utilization In Louisiana, Sean M. Prados

All ETDs from UAB

Two significant events transpired in Louisiana that had sweeping changes for the healthcare system between 2013 and 2016: (1) the privatization of the nation's only stateowned Charity Hospital System via cooperative endeavor agreements with local, private hospitals known as public-private-partnerships (PPP), and (2) the implementation of Medicaid expansion, referred to as implementation of the Affordable Care Act (ACA). Either event independently could have had significant utilization and financial implications for hospitals. This retrospective, quasi-experimental research implemented a generalized estimating equation (GEE) analysis to examine the effects of PPP and ACA on Medicaid patient emergency department utilization by PPP hospital designation, …


Grainyhead-Like 2 (Grhl2) Has Anti-Oncogenic Potential In Glioblastoma, Rachel M. Carnes Jan 2022

Grainyhead-Like 2 (Grhl2) Has Anti-Oncogenic Potential In Glioblastoma, Rachel M. Carnes

All ETDs from UAB

Grainyhead-like 2 (GRHL2) is a complex transcription factor associated with roles in both development and cancer. In development, GRHL2 suppresses a series of genes associated with the mesenchymal phenotype, while actively promoting the expression of genes associated with the epithelial phenotype. Due to this GRHL2 is considered a main gatekeeper of the epithelial to mesenchymal transition (EMT), playing a crucial role in epithelial morphogenesis and neural tube closure. These basic traits for GRHL2 have also been found to be similar in cancer. GRHL2 has multi-faceted functions in cancer, in which it can be considered either an oncogene or a tumor …

The Role Of Dock3 In Normal Skeletal Muscle Function And Metabolism, Adrienne Samani

All ETDs from UAB

DOCK (dedicator of cytokinesis) are proteins of an 11-member family of typical guanine exchange factors (GEFs) expressed almost exclusively in the brain and spinal cord. Human pathogenic DOCK3 variants have been identified to cause debilitating neuromuscular phenotypes such as muscle hypotonia, ataxia, and intellectual disability. Our lab identified DOCK3 as being strongly upregulated in Duchene muscular dystrophy (DMD), specifically in the skeletal muscles of DMD patient and mouse skeletal muscles. Global Dock3 KO mice on the dystrophin-deficient background exacerbated skeletal muscle and cardiac phenotypes. Similarly, DOCK3 KO mice appeared to have poor muscle architecture, locomotive activity, reduced myogenic fusion, impaired …

The Role Between Transactive Memory Systems In The Relationship Between Psychological Safety & Quality In Interprofessional Healthcare Teams, Tera L. Webb

All ETDs from UAB

During uncertainty, the optimum solution for work-related problems or patient care cases require the scopes of practice and competencies beyond a single profession. For this reason, the collaborative efforts of interprofessional teams are a widely used approach to patient care and medical decision making. The interdependency between healthcare professionals with varied expertise and input often lead to desired outcomes. Beyond the structure of the team, there are numerous cognitive processes at play that impact knowledge transfer in highly skilled teams that impact outcomes. Therefore, this dissertation will review relevant literature on two cognitive constructs – psychological safety and transactive memory …

m

Connective tissue disease-related interstitial lung disease (CTD-ILD) results in an unrelenting symptom burden and may progress to death. The morbidity and mortality associated with CTD-ILD likely has a profound impact on individuals’ quality of life (QOL). Quality of life is a phenomenon that has yet to be sufficiently described in the literature on CTD-ILD. The factors associated with QOL in other chronic lung diseases have been described, but because of the different clinical and demographic characteristics of CTD-ILD, it is unknown if these same factors are associated with QOL in CTD-ILD. The purpose of this study was to examine …


The Role Of Alternative Payment Models In Pharmaceutical Services And Outcomes, Matthew G. Parker Jan 2022

The Role Of Alternative Payment Models In Pharmaceutical Services And Outcomes, Matthew G. Parker

All ETDs from UAB

A persistent challenge within the healthcare sector is balancing cost containment for health services and the quality of care associated with these services. This challenge has reinvigorated interest in alternative payment models (i.e., risk-sharing, shared savings, capitation), arrangements between payers and healthcare providers that structure reimbursement for services based on health outcomes. Although much research has assessed the association between these payment models and financial outcomes for medical services, there is a paucity of research that has likewise assessed pharmaceutical outcomes (i.e., electronic prescribing, evidence-based prescribing, medication adherence). The papers comprising this dissertation contribute to this limited body of research …

Superhero Media And Risk-Taking: Is Superhero Play A Risk Factor For Unintentional Injury In Preschool-Aged Children?, Casie H. Morgan Jan 2022

Superhero Media And Risk-Taking: Is Superhero Play A Risk Factor For Unintentional Injury In Preschool-Aged Children?, Casie H. Morgan

All ETDs from UAB

The preschool years represent a time of rapid human development, hallmarked by exploring one’s environment through gross and fine motor movement, touching and tasting physical objects, and imaginative pretend play. This exploration is developmentally appropriate, but also presents risks. Unintentional injury is the leading cause of death for preschool-aged children, and common injuries reflect exploration and risk-taking exhibited during play. Pretend play may be particularly risky if children imitate risky models like superheroes. Superhero media is extremely popular among young children, leading many children to identify closely with superheroes. Frequent exposure and subsequent identification with superheroes is concerning because media …

Synergy Between Stenotrophomonas Maltophilia And Pseudomonas Aeruginosa During Polymicrobial Airway Infections, Melissa Skye Mcdaniel Jan 2022

Synergy Between Stenotrophomonas Maltophilia And Pseudomonas Aeruginosa During Polymicrobial Airway Infections, Melissa Skye Mcdaniel

All ETDs from UAB

Stenotrophomonas maltophilia is a Gram-negative bacillus that can act as an opportunistic pathogen in patients with respiratory diseases, including cystic fibrosis (CF) and ventilator-associated pneumonia. Infection with S. maltophilia is associated with worse lung function, but it remains unclear if this organism contributes directly to lung function decline. Lung infections are often polymicrobial, and S. maltophilia can be isolated from the lung with the key pulmonary pathogen Pseudomonas aeruginosa. In the first half of this work, we investigated the pathogenicity of S. maltophilia alone and during polymicrobial infection with P. aeruginosa. We used respiratory infections in mice to assess persistence …

Evaluation Of A Living Shoreline Technique On A Southeastern United States Reservoir, Eric V. Muth Jan 2022

Evaluation Of A Living Shoreline Technique On A Southeastern United States Reservoir, Eric V. Muth

All ETDs from UAB

The impoundment of rivers in the southeastern United States has led to the creation of reservoirs that have seen the riparian zone become heavily developed with residential real estate. As the hybrid river/lake systems started forming new shorelines, property owners reacted by attempting to reduce their losses. This has been done in a variety of ways, with the majority falling into the bulkhead category. The use of vertical hard armament has resulted in a loss of ecological function and an increase in erosion of the lakebed at the toe or escarpment. In response to this, the idea was proposed by …


Molecular Imaging Of Cancer For Detection And Monitoring Of Response To Combination Therapy, Tiara S. Napier Jan 2022

Molecular Imaging Of Cancer For Detection And Monitoring Of Response To Combination Therapy, Tiara S. Napier

All ETDs from UAB

Imaging is a primary component of cancer care and aids in diagnosing, response assessment, and monitoring. Molecular imaging techniques provide visualization of unique tumor biology that can be used to personalize treatment. Key features of an effective biomarker are sensitivity, specificity, and ability to provide clinical value beyond that of other types of information already available at the time of diagnosis. For particularly heterogeneous cancer subtypes, such as glioblastoma (GBM) and triple negative breast cancer (TNBC), reliable biomarkers can be challenging to identify and there are few tar-getable receptors for therapy. Our findings demonstrate that quantifying tumor EGFR (panitumumab-IRDye800CW), granzyme …


Restoring The Sphingolipid Balance In Glioblastoma, Cyntanna C. Hawkins Jan 2022

Restoring The Sphingolipid Balance In Glioblastoma, Cyntanna C. Hawkins

All ETDs from UAB

Glioblastoma (GBM) is a highly aggressive brain tumor with a median survival of 15 months even with standard of care—surgical resection, radiotherapy, and chemotherapy. Two of the key characteristics contributing to this malignancy are its highly invasive phenotype and resistance to the chemotherapy, temozolomide (TMZ). We, and others, have identified the sphingolipid balance as a driver of these phenotypes with dysregulated sphingolipid metabolism seen in GBM patient samples. The ceramidases, specifically acid ceramidase (ASAH1), mediate the balance between ceramides and sphingosine-1-phosphate (S1P). ASAH1 breaks down ceramides ultimately forming S1P. While ceramides induce cell death, S1P promotes migration and cell survival. …
