Validity And Test-Retest Reliability Of A Digital Dynamic Visual Acuity Test Of Vestibular Function, Lydia F. Grunstra, Courtney D. Hall, Kara D. Stressman

Undergraduate Honors Theses

The vestibular system senses head motion and facilitates gaze stabilization, allowing for clear vision during movement. The vestibulo-ocular reflex (VOR) causes the eyes to move opposite head motion, thus maintaining focus on a target. Consequently, uncompensated loss of vestibular function leads to reduced VOR function resulting in dizziness, nausea, and visual disturbance. Different testing methods have been developed to measure VOR loss. These tests generally require bulky, expensive equipment, and must be performed by a trained examiner. A newly developed digital form of the dynamic visual acuity (DVA) test requires less equipment, is cost-effective, and may be performed at home …

Nonmedical Stimulant Use In An Undergraduate College Student Sample: Demographics, Academics, Stress, And Other Substance Use, Ashley Skye Vanover, Meredith K. Ginley, Shelby Whalan

Undergraduate Honors Theses

Nonmedical use of prescription stimuluants (NMUS) can cause adverse outcomes for college students including academic impediments, such as a lowered GPA, and polyuse of illicit substances (Garcia et al., 2021; Holt & McCarthy, 2019; Norman & Ford, 2018). The current study investigated the demographics, academics, stress, and polysubstance use between students who endorsed NMUS and those who did not in an undergraduate college population sample at a large public university in the Southeast. The sample consisted of 429 undergraduate students who completed online measures of demographics, perceived stress, stressful life events, and substance use. Overall, 3.4% of the sample reported …

Nicotinamide Riboside And Beta-Hydroxybutyrate Activate Parallel Pathways For C. Elegans Lifespan Extension, Mckenzie Peters

Undergraduate Honors Theses

Supplementation with nicotinamide riboside (NR), a form of vitamin B3 and a precursor of nicotinamide adenine dinucleotide (NAD⁺) extends lifespan in the nematode C. elegans and delays aging-related pathologies in mammals. During aging, levels of NAD⁺ decline causing metabolic dysfunction and oxidative damage. Studies in C. elegans found that when NR was administered during larval development it induced the mitochondrial unfolded protein response (UPR^mt), which is frequently associated with lifespan extension. Both calorie restriction (CR) and ketogenic diets (KD) have been shown to extend lifespan, in part through increasing NAD⁺ and through increasing levels …

Sexual Dimorphism Of Glomerular Capillary Morphology In Rats, Zackarias Coker

Undergraduate Honors Theses

Chronic kidney disease (CKD) progresses faster in males than females; however, the underlying mechanisms remain poorly understood. Sex differences in glomerular capillary morphology has been hypothesized to contribute, in part, to the increased susceptibility to hypertension-induced renal injury and CKD progression in males, but this has not been investigated. The goal of the present study was to assess glomerular capillary morphology in male vs. female rats with intact kidneys and after uninephrectomy (UNX). We hypothesized that glomerular capillary radii (R_CAP) and length (L_CAP) would be greater in male rats.

Male (n=4) and female (n=4) with intact …

Type 1 Diabetes In The Classroom, Ursula Herrell

Undergraduate Honors Theses

Type 1 diabetes [T1D] is an autoimmune disease that presents in a pathophysiological disorder as insulin deficiency. Managing this illness during childhood is a constant challenge of maintaining blood glucose levels within a healthy range, resulting in increased stress for children and caregivers. School attendance is one factor that may result in increased stress. Studies have highlighted the fact that teachers of students with T1D may receive little education regarding management of the disease and may be required to make accommodations which can result in confusion, miscommunication, and increased psychosocial stress. The goal of this research was to learn about …

Determining The Effects Of Maternal Adiposity On Preterm Neonatal Microbiome And Short Chain Fatty Acid Profiles, Dalton James, William A. Clark Phd, Kristy L. Thomas

Undergraduate Honors Theses

The gut microbiota and its metabolites have vast impacts on the human digestive system, immune system, and health outcomes. Short chain volatile fatty acids (SCVFAs) present in feces can be representative of the interactions of the microbiota present in the gut. Low microbiota diversity in the human gut is highly associated with obesity and adverse health outcomes. Furthermore, the maternal microbiome has a direct impact on neonatal microbiota through various pathways such as environment, skin flora, breast milk composition, and vaginal secretions. This study is aimed to further understand the associations between various factors (maternal adiposity, gestational time, length of …

Nutrition Needs Assessment For Women Of Childbearing Age With Polycystic Ovarian Syndrome, Callie Coleman, Whitney Bignell

Undergraduate Honors Theses

Polycystic Ovarian Syndrome (PCOS) is an endocrine disorder that affects women’s menstrual cycles, androgen (male hormones) levels, and cysts on the ovaries. This endocrine disorder has various symptoms, with insulin resistance as a hallmark symptom. Approximately 65-70% of women with PCOS have insulin resistance and hyperinsulinemia, whether or not they are overweight, obese, or lean (Marshall & Dunaif, 2012). Many women with PCOS struggle to lose weight because their excess weight is related to nutrition, lifestyle factors, and imbalanced hormones. Understanding PCOS as a metabolic disorder with nutritional implications led to investigating the potential benefit of having registered dietitian nutritionists …

An Examination Of The Impact Of Covid-19 On The Job Satisfaction And Emotional Well-Being Of Icu Nurses, Laura Ruth Daffron

Undergraduate Honors Theses

Healthcare systems have been demonstrably altered because of the COVID-19 pandemic. Resources were stretched and patient conditions deteriorated on a scale previously unseen, leaving nurses at the forefront to face the adversities brought about by the pandemic. In this study, a questionnaire was utilized to better understand how COVID-19 has impacted the stress level, resilience/well-being, moral distress, job satisfaction/enjoyment, practice environment, and intent to remain in the nursing profession of nursing alums from East Tennessee State University. This study focused on a subset of nurses working in critical care, to consider the impact that the pandemic had on ICU nurses’ …

Justification And Compliance: Public Health Ethics In A Post-Covid America, Nathan Alan Turner

Undergraduate Honors Theses

The severity of the COVID-19 pandemic and the high-profile nature of the public health response make it a natural context for exploring the current state of public health ethics. This paper explores this topic from two perspectives: justification and compliance. Libertarianism and utilitarianism are two frameworks that dominate the question of how public health interventions are justified. Consequently, this paper analyzes the events of the pandemic to determine how these frameworks fared in terms of offering reliable means of justifying the interventions needed to curb the spread of COVID-19. Consideration of these events suggests that a framework centered around actionable …

A Tri-Culture Model For Examining Polymicrobial Interactions, Mason Stanley

Undergraduate Honors Theses

Candida albicans is a fungal microbe that is often present inside of humans in the mouth and gastrointestinal tract. It shares a mostly commensal relationship with its hosts but can develop into an opportunistic pathogenic infection under conditions of immune suppression. Oral thrush or candidiasis is an uncomfortable condition resulting from excessive growth of Candida albicans in the oral cavity. Candidiasis is prone to progressing into more threatening symptoms without proper treatment. There are few effective antifungal medicines used for treatment and the problem of antimicrobial resistance is growing. Alcaligenes faecalis is a bacterial microbe that does not pose a …
