Rural-Urban And Within-Rural Differences In Covid-19 Mortality Rates, Yue Sun, Kent Jason G. Cheng, Shannon M. Monnat

Journal of Rural Social Sciences

Since late-2020, COVID-19 mortality rates have been higher in rural than in urban America, but there has also been substantial within-rural heterogeneity. Using CDC data, we compare COVID-19 mortality rates across the rural-urban continuum as well as within rural counties across different types of labor markets and by metropolitan adjacency. As of October 1, 2021, the cumulative COVID-19 mortality rate was 247.0 per 100,000 population in rural counties compared to 200.7 in urban counties. Higher COVID-19 mortality rates in rural counties are explained by lower average educational attainment and lower median household income. Within rural counties, mortality rates have been …

Rates And Perceptions Of Covid-19 Vaccination From University Of Mississippi Students, Josie Parham

Honors Theses

The trials, tribulations and triumphs of the global COVID-19 pandemic are impacted by and are a product of behaviors that occur at the level of nations, states, cities and, ultimately, communities. In the wake of the development of safe and effective vaccines against SARS-CoV2, the virus responsible for the pandemic, the significance of the vaccine is closely linked to the number of individuals that receive the vaccine. To date, surveys have measured sizable variations in vaccination rates between nations, states, cities, and communities. Focusing on events that have transpired in one such local community, the present study (i) measured the …

The Effects Of Thc On Hiv Tat Protein-Mediated Neuroinflammation, Camille Martin

Honors Theses

Although antiretroviral therapies have allowed people living with human immunodeficiency virus (HIV) to achieve normal life expectancies, they cannot cure HIV nor the neurological symptoms associated with infection, termed neuroHIV. NeuroHIV describes a myriad of neurological disorders including mood disorders (depression and anxiety), cognitive impairment, neuropathic pain, and motor disinhibition. The mechanisms by which HIV promotes neurological impairment are not known, but may involve actions of its neurotoxic proteins. One such protein that has been well-characterized is the HIV trans-activator of transcription (Tat). Tat exerts neurotoxic effects via various means, one of which is to activate microglia, the macrophages of …

Effects Of Music Exposure On Autobiographical Memory In Alzheimer's Patients: A Systematic Review And Meta-Analysis, Gregory Vance

Honors Theses

The progression of Alzheimer’s disease is primarily characterized by a loss of memory concerning past events, as well as a lack in ability to create new memories. While this spans across many subsets of memory, such as recognition, recall, and autobiographical memory, there seems to be a lesser impact on musical memory in those with Alzheimer’s. Multiple studies have suggested that exposure to music and introduction of music therapy can even improve other aspects of memory in Alzheimer’s patients. This systematic review and meta-analysis sought to examine the relationship between music exposure and autobiographical memory specifically. A pool of electronic …

The Role Of Age Ligand And Rap1a In Myofibroblast Signaling Cascade In Type 2 Diabetes Mellitus-Induced Cardiomyopathic Conditions, Camilla Puglia

Honors Theses

Diabetes is one of the leading causes of death in the United States, taking more than 90,000 lives annually. Type 2 diabetes mellitus-induced cardiac fibrosis is a common condition seen in diabetic patients. The AGE/RAGE signaling cascade has been strongly associated with this supposed cardiac fibrosis along with hyperactive myofibroblasts which excessively remodel extracellular matrix tissue, leading to damaged and enlarged heart muscle tissue. In diabetic patients, Advanced Glycation End Products (AGEs) are produced in abundance and accumulate in the extracellular matrix of heart tissue. To investigate the role of of the AGE ligand on fibroblast behavior, increasing amounts of …

The Effect Of Age Concentration And Glucose Levels In Rage-Mediated Cardiac Fibroblast Migration In Type 2 Diabetes, Lorral Kanauss

Honors Theses

Diabetes is one of the largest health concerns in the United States. Its continuous increase in prevalence has led to it being one of the largest healthcare costs and consistently listed as one of the leading causes of death. That being said, diabetes also increases the risk of other health conditions, one of which is cardiovascular disease. Left ventricle hypertrophy resulting in the stiffening of the left ventricle and diastolic dysfunction is one form of cardiovascular disease associated with diabetes. Thought to be impacted by decreased fibroblast migration in the extracellular matrix, the experiments performed in this study seek to …

Content Analysis Of Vitiligo Portrayal On Social Media, Mary Miller

Honors Theses

Given that vitiligo affects a small percentage of the world population, and its affects are not widely known, there is an increasing need to learn of its effects on those with vitiligo, both physical and psychological. Social media has become an influential platform to spread awareness and build confidence in those with vitiligo. This study aims to find how vitiligo is portrayed through social media using content analysis procedures. This is a cross-sectional content analysis that utilized a codebook to analyze Instagram posts. The results were analyzed by interrater reliability and frequency for each coder. The findings of this content …

The Role Of Mitochondrial Dysfunction In Causing Hypertension During Pregnancy As Observed In The Rupp Model Of Preeclampsia, Michael Franks

Honors Theses

Preeclampsia (PE) is a disease characterized by new-onset hypertension in the third trimester of pregnancy, endothelial dysfunction, and placental ischemia. Contributory to these characteristics are circulating factors such as agonistic autoantibodies to the angiotensin I type II receptor (AT1-AA), CD4+ T cells, natural killer cells (NK), and oxidative stress, which I will show to contribute to renal and placental mitochondrial dysfunction during pregnancy. The adoptive transfer of CD4+ T cells from the Reduced Uterine Perfusion Pressure (RUPP) rat model of PE to a healthy normal pregnant rat has been shown to result in many of these characteristics, including AT1-AA production. …

Efficacy Of Δ-9-Tetrahydrocannabinol For Hiv-Related Neuropathic Pain, Kaia Horne

Honors Theses

Despite the availability and success of antiretroviral therapeutics, ~30% of patients living with HIV experience neuropathic pain that is often intractable. The mechanisms are not known, but there is evidence to support a role for the HIV virotoxins, Tat and/or gp120, which can damage or degenerate neurons and peripheral nerves. One mechanism by which Tat and gp120 promote nerve damage involves the stimulation of proinflammatory cytokine production from immune cells which can damage or kill bystander cells. Notably, compounds found in Cannabis exert anti-inflammatory effects and many studies report HIV patients to consume more marijuana than seronegative individuals. When people …

(Under the direction of Dr. Xin Dang)

By tracking and analyzing fifty-three weeks of COVID-19 data, this thesis analyzes the efficacy of the COVID-19 vaccine within the State of Mississippi. Over the course of these fifty-three weeks, I have also been able to calculate the confidence intervals for vaccination efficacy and the risk reduction due to vaccination by using data regarding the correlations between deaths and vaccination status, provided to me by the Mississippi Office of Epidemiology. My analysis demonstrates that the COVID-19 vaccine is effective not only in Mississippi but also …

Characterizing The Roles Of Cannabinoid Receptor 1 & 2 In Zebrafish Behavior, Metabolism, And Seizure-Induced Activity, Kayci Kimmons

Honors Theses

Epileptic disorders like Dravet Syndrome require novel studies to determine the most ideal treatment. New research linking the endocannabinoid system (ECS) to epileptic disorders is arising, but there is still much to be discovered about the function and regulatory impact of the endocannabinoid system and its receptors in epilepsies like Dravet. In this study, knockout models of larval and adult zebrafish (Danio rerio) were used to investigate the roles of cannabinoid receptors 1 & 2 in behavior, brain mitochondrial metabolism, and seizure-induced activity following exposure to THC and CBD. Larval zebrafish which lacked cannabinoid receptor 1 exhibited increased …

Ameliorative Effects Of Minor Cannabinoids Over Hiv-1 Tat-Mediated Visceral Pain, Charlie Worth

Honors Theses

As the total number of people living with HIV continues to rise across the world, an effective HIV treatment is still sought after. While modern-day advanced therapies exist for mitigating much of the negative effects of HIV, the virus remains evasive and problematic in the central nervous system. Thus, even with treatment, many people living with HIV continue to suffer from a plethora of symptoms. However, a large proportion of HIV-positive patients claim to feel a reduction in those persevering symptoms after cannabis usage. This anecdotal evidence has sparked interest in the efficacy of cannabis constituents for HIV therapy. This …

Occupational Fine Particulate Matter Exposure And Its Associated Effects On The Cardiovascular System: A Systematic Review, Jordan Rickwa

Honors Theses

Fine particulate matter (PM2.5), the solid and liquid portion of air pollution under 2.5 microns in diameter, has been shown to cause numerous negative effects on the body. These inhalable particles are often researched for their effects on the respiratory system in outdoor settings, however systemic health impacts have been observed following inhalation of PM2.5 . Additionally, exposures to PM2.5 can occur in occupational settings but are less frequently studied compared to outdoors. This literature review seeks to identify studies that determined associations between inhaled PM2.5 and the resulting cardiovascular effects in occupational settings. We conducted a search of literature …
