Evaluating Social Support And T2d Risk Factors Among Members Of Rural-Dwelling Grandparent-Headed Households, Brittany L. Smalls, Abebola Adegboyega, Kelly Nb Palmer, Jennifer Hatcher

Journal of Appalachian Health

Purpose: This study examines the associations of social support and type 2 diabetes (T2D) risk factors among members of rural-dwelling, grandparent-headed households (GHH).

Methods: Prospective data were collected from rural-dwelling members of GHH with no known diagnosis of T2D. Data collected on family characteristics, T2D clinical risk factors, and social support were assessed.

Results: Sixty-six grandparents and 72 grandchildren participated in the study. The average age and HbA1Cs were 59.4 years and 6.2% ± 1.4 for grandparents and 11.8 years and 4.9% ± 0.6 for grandchildren. Most grandparents were found to have prediabetes or undiagnosed diabetes. The number of people …

Maximal Strength Training Increases Metabolic Energy Expenditure In Sedentary Adults Classified As Obese, Robert E. Anderson Iii

Theses and Dissertations--Nutrition and Food Systems

Background: Metabolic adaptations reduce resting and non-resting energy expenditure to account for approximately 120 kcal/day. Weight loss promotes greater skeletal muscle efficiency, reducing the energy cost of physical activity and is correlated with declines in skeletal muscle glucose oxidation. Maximal Strength Training (MST) has the potential to upregulate glucose utilization and may offset these metabolic adaptations. Objective: To determine if MST offsets markers of metabolic adaptation by increasing resting and non-resting energy expenditure in sedentary individuals classified as obese. Methods: Five (5) participants (2 females, 3 males), ages 18-35 years, with obesity (BMI 30–45 kg/m2) were enrolled in an 8-week …

An Investigation Of Hhv6'S Impact On The Cognitive Progression And Microglial Changes In An Alzheimer's Disease Cohort, Charles E. Seaks

Theses and Dissertations--Physiology

The role of herpesviruses and, more specifically, HHV6 in the development of Alzheimer’s disease (AD) and associated cognitive decline is still being investigated. High ubiquity and prevalence in the population have led to a high degree of skepticism about HHV6 as a potential contributor to cognitive decline and dementias. However, recent evidence related to another herpesvirus, herpes simplex virus 1, suggests that reactivation, not carriage, of the virus may be the key factor to explain the dissonance between the virus’ ubiquity and contributions to dementias. With that in mind, we set out to assess cases from the Sanders-Brown Center on …

The Relative Contribution Of Liver And Intestine In Reverse Cholesterol Transport, Rupinder Kaur

Theses and Dissertations--Pharmacy

Despite decades of advances in research, death due to cardiometabolic disease remains the largest contributor to mortality in the US. While present therapies oppose “forward cholesterol transport,” and atherosclerotic plaque progression, they do not remove cholesterol from established atherosclerotic plaques. Reverse cholesterol transport (RCT) is the active process of mobilizing peripheral cholesterol for excretion through the hepatobiliary (transhepatic cholesterol elimination, THCE) or intestinal (transintestinal cholesterol elimination, TICE) pathways. Currently, there are no clinically approved therapeutics that target RCT. Elucidation of the mechanisms that govern RCT and TICE, and the subsequent identification of novel targets is of importance. The present work …

Estrogen Regulation Of Daily Metabolic Rhythms In Female Mice, Oluwabukola Omotola

Theses and Dissertations--Biology

Circadian rhythms are approximately 24-hour cycles of behavior, physiology, and gene expression. In mammals, these circadian rhythms are generated by clocks located in nearly every tissue in the body. The function of circadian clocks is to synchronize physiology and behavior with environmental cycles such as the light-dark cycle. After menopause, when circulating levels of estrogens are very low, women are more susceptible to obesity comorbidities such as metabolic syndrome and cardiovascular disease, suggesting that estrogens regulate these processes. Estrogens could protect females from metabolic dysfunction by regulating circadian rhythms. Consumption of diets that are high in fat contribute to obesity. …

Increasing Staff Compliance With Routine Hcv Screening And Improving Linkage To Care Among Patients Testing Hepatitis C Positive In The Emergency Department, Carson G. Swartz

DNP Projects

Background: Hepatitis C virus (HCV) is a blood-borne pathogen that can cause severe liver disease, cancer, and death and is a significant source of morbidity and mortality in the United States. Several academic medical centers including University of Kentucky Healthcare have implemented routine HCV screening for patients presenting to the emergency department (ED) and have discovered a large viral burden amongst patients who are often symptomatic.

Purpose: The purpose of this doctoral project is to increase staff compliance, confidence, and education regarding the HCV screening process in an urban, Level I emergency department, as well as to evaluate whether an …

Interleukin-1 Receptor 1 Signaling In Mild Tbi: Do Endothelial Cells Play A Major Role?, Colleen N. Bodnar

Theses and Dissertations--Neuroscience

Across the world, over 69 million people sustain a traumatic brain injury (TBI) per year making TBI a major health concern worldwide. Of all the TBIs that occur each year, it is suggested that up to 90 percent are mild in nature. Even a mild TBI causes both physical damages to the cells of the brain and activation of a variety of biochemical cascades. Inflammation is an extremely common pathology seen in the brains of TBI survivors of all severities. Chronic inflammation can cause detrimental effects within the brain including neurodegeneration. A major pro-inflammatory cytokine, interleukin-1 (IL-1), is upregulated within …

An Ecological Study Of Glyphosate Use And Non-Hodgkin’S Lymphoma, Dexter Corlett, Steven R. Browning

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

Glyphosate is currently the most widely used herbicide in the world. Initially thought to be non-carcinogenic in humans, in 2015 glyphosate was classified as a “probable carcinogen” by the International Agency for Research on Cancer due to several small epidemiological studies indicating a link between the pesticide and hematologic cancers, especially non-Hodgkin’s lymphoma (NHL). The current work is an ecological study using counties in Kentucky, Arkansas, and Iowa to compare glyphosate usage to NHL incidence using a multivariate Poisson regression. We found no significant correlation between glyphosate use and NHL incidence, though caution should be taken to draw significance from …

Mammalian Target Of Rapamycin Cell Signaling Pathway In Phosphatase And Tensin Homolog Induced Kinase 1 Knockout Rat Model Of Familial Parkinson's Disease, Martha Helena Mortell

Theses and Dissertations--Medical Sciences

More than 10 million people are living with Parkinson’s disease (PD), one million of which are people in the United States. PD is the second most common age-related neurodegenerative disorder, after Alzheimer’s disease, and is characterized by the accumulation of a-synuclein aggregates and the degeneration of dopaminergic neurons. The loss of endogenous dopamine in PD brain accounts for the motor decline presented clinically in PD patients. Etiological factors of PD include oxidative damage and inflammation, although the detailed mechanisms remain unknown. Risk factors for PD include gender, age, environmental factors, and gene mutations.

The current thesis research employed phosphatase and …

Apoe Genotype And Sex Modulate Ketogenic Diet Enhancements To Metabolism And Gut Microbiome In Young Mice, Andrew T. Yackzan

Theses and Dissertations--Medical Sciences

The apolipoprotein ε (APOE) allele in humans has been associated with risk for development of Alzheimer’s disease (AD). There are predominately three variations of the allele – ε2 (E2), ε3 (E3), and ε4 (E4) – with E4 contributing the greatest risk of AD development. Recent research has unveiled evidence of neurometabolic and neurovascular deficits in E4 carriers present decades before the onset of dementia; it is believed these chronic defects play a major role in the development of AD, thus making them a potential target for preventative intervention. The purpose of this study was to examine the effect of a …

Modeling The Effects Of Adverse Childhood Experiences Using A Mouse Model Of Neglect: Mechanisms Of Adiposity Expansion In Females, Jacqueline Leachman

Theses and Dissertations--Pharmacology and Nutritional Sciences

Adverse childhood experiences (ACEs) are an independent risk factor for chronic disease, including obesity and metabolic syndrome. We have previously shown that a mouse model of early life stress, maternal separation and early weaning (MSEW), exacerbates high-fat diet (HF)-induced obesity only in adult female mice. In agreement, the analysis of several cohorts of participants exposed to ACEs have shown that women are more susceptible to develop obesity than men. Therefore, the aim of this study was to investigate the link between early life stress and obesity in pre-clinical and clinical settings. Male and female MSEW mice fed 1 week a …

Progressive Endoscopic Approach To Balloon Dilation For Benign Esophageal Strictures, Chad J. Cooper

Theses and Dissertations--Clinical and Translational Science

Benign esophageal strictures are a frequently encountered problem in clinical practice. The management of benign esophageal strictures have slowly evolved over the decades based on “expert opinion.” Despite vast amounts of data about the efficacy and safety of dilation, unfortunately there is no consensus on a systematic and safe approach that is efficient, limits complications and provides long lasting improvement of dysphagia. Our group designed a progressive approach to endoscopic balloon dilation based on tailoring certain technical aspects of the dilation process.

Most studies in the literature concluded that endoscopic dilation is safe and effective in relieving dysphagia caused by …

Antibiotic Permeation In Gram-Negative Bacteria And Contribution Of Inflammasome Activation And Pyroptosis In Pathogenesis Of Salmonella Systemic Infection, Ankit Pandeya

Theses and Dissertations--Chemistry

Antibiotic resistance is one of the major global issues in the field of public health and medicine. Good antibiotic candidates need to be selectively toxic, inhibit cellular target, and effectively penetrate and accumulate in bacterial cells. The last factor is a formidable barrier in the development of antimicrobials effective in Gram-negative bacteria, due to the presence of two layers of cell envelope. The first half of my thesis focuses on understanding the permeation of small molecules through this formidable cell envelope, distribution inside the cell of Gram-negative bacteria, and design of novel methods to make small molecules effectively cross the …

Nicotine And Cotinine: Microbial Modulators Of The Immune Response, Jourdan Lakes

Theses and Dissertations--Chemistry

The consumption of tobacco products is a known contributor to a variety of health conditions and disease pathologies including cardiovascular and lung diseases. In addition to these well-known pathological effects of tobacco use, it has been established recently that tobacco consumption as well as nicotine consumption alone results in distinct, dysbiotic perturbations to the enteric microflora of the gastrointestinal tract. Previous research into the intestinal microbiome has demonstrated that these microbes are active contributors to the maintenance of a homeostatic and tolerogenic environment within the host. In fact, the presence of our enteric microflora is necessary for the proper development …
