All ETDs from UAB

As the average lifespan increases, older adults are remaining independent into older ages than before. The ability to drive a vehicle is an essential part of daily living that helps older adults maintain independence. Cognitive training, specifically speed of processing training (SOPT), is an intervention that has consistently shown to benefit older adult’s driving abilities and driving behaviors. This dissertation examined the longitudinal association between cognitive training and primary driving location on crash risk across 20 years (Paper 1), investigated the effects of cognitive training and dosage on driving mobility across 10 years (Paper 2), and explored social determinants of …


Predicting Maximum Concentric And Eccentric Squat Strength From Maximum Isometric Squat Strength, Michael A. Dunn Jan 2024

Predicting Maximum Concentric And Eccentric Squat Strength From Maximum Isometric Squat Strength, Michael A. Dunn

All ETDs from UAB

Resistive squat exercise is a well-established technique to enhance the strength of muscles and bone of the back in humans. Such type of exercise could prove highly beneficial for individuals with pathological condition of the back such as osteoporosis. Notably, the rehabilitation programs aimed at strengthening the muscles and bone of the back require the knowledge of the patient’s one repetition maximum (1RM). Finding the 1RM squat value could lead to injury due to the higher weights involved. In addition, testing for 1RM could be not feasible in older populations or young population with chronic back conditions The isometric squat …

Aging With Hiv And Comorbid Chronic Obstructive Pulmonary Disease, Jun Yeong Byun

All ETDs from UAB

Older adults with human immunodeficiency virus (HIV) experience a high prevalence of chronic obstructive pulmonary disease (COPD). Considering having either HIV or COPD is related to worse health outcomes in older adults, aging with both HIV and COPD may synergistically and negatively affect the health outcomes of older people with HIV (PWH) and comorbid COPD. The purpose of this dissertation was to explore the aging of PWH with COPD. This purpose was accomplished through three articles: 1) an adaptation of a gerontological model investigating what is known about the aging of PWH and people with COPD and extrapolating that to …


Pharmacologic Proteasome Activators Ameliorate Alzheimer's-Like Pathology In Ad Fly Models, Mehar Bano Jan 2023

Pharmacologic Proteasome Activators Ameliorate Alzheimer's-Like Pathology In Ad Fly Models, Mehar Bano

All ETDs from UAB

The proteasome is a large multi-subunit protease responsible for the degradation and removal of oxidized, misfolded, and polyubiquitinated proteins. The proteasome plays a critical role in nervous system processes. This includes the maintenance of cellular homeostasis in neurons (1). It also includes synaptic efficacy and plasticity as well as protein turnover, presynaptic vesicle transport, and neuronal protesostasis. Proteasome function is impaired as a consequence of aging, which is aggravated by conditions like Alzheimer's Disease and Related-Dementias (AD, ADRD) (2). According to earlier work from our lab the proteasome is critical to how quickly AD progresses. In Drosophila, human cells, and …


Role Of Dpy30 In The Epigenetic Regulation Of Odontoblast Differentiation In Vitro, Namrata Landge Rana Jan 2023

Role Of Dpy30 In The Epigenetic Regulation Of Odontoblast Differentiation In Vitro, Namrata Landge Rana

All ETDs from UAB

Purpose: Dentin is produced from odontoblasts, derived from human Dental Pulp Cells (hDPCs), which are essential for dentin formation, remodeling, and mineral hemostasis. Epigenetic mechanisms are believed to be involved in odontoblast differentiation and function, and H3K4 methylation is associated with gene activation which is fundamental to histone-based epigenetics. The SET1/MLL complexes are mammals' major histone H3K4 methylation enzymes. DPY30 is a core subunit of SET1/MII complexes, mammalian's major histone H3K4 methyltransferases. It plays an important role in regulating fundamental processes including the determination of cell lineage, growth, and differentiation. Thus, histone-based epigenetic mechanisms are involved in odontoblast differentiation and …


Successful Aging Among Midlife Black Women: A Latent Class Analysis, Joshua Christian Julian Lewis Jan 2023

Successful Aging Among Midlife Black Women: A Latent Class Analysis, Joshua Christian Julian Lewis

All ETDs from UAB

Successful aging (SA), as outlined by Rowe and Khan, with its objective focus on disease and disability avoidance, maintaining high physical and cognitive function, and sustaining engagement in social and productive activities, was meant to be a benchmark for assessing health and aging. However, given its rigid criteria virtually no one “ages successfully” despite being in otherwise relatively good health. The assumption of unsuccessful aging in populations who experience a higher prevalence of chronic disease, illness, disability, and other health disparities, is implicit in the SA framework outlined by Rowe and Khan and would preclude many Black women from being …

Labor Union Membership Tenure And Midlife Health: A Gendered Perspective, Clifford Ross

All ETDs from UAB

The benefits of labor unions have not gone unstudied. Individuals in labor unions have better access to lower cost/more substantial health insurance plans, higher quality pension plans, and better wages leading to increased lifetime earnings. Even though many of these benefits create important pathways that could lead to better health, unions have been paid little attention in health literature. Additionally, in the modern workplace Mothers are offered lower starting salaries, are perceived as less competent, and face a penalty regarding hiring, promotion, and workplace educational opportunities. Compared to men, women with children see an income gap 20 cents wider than …


Multilevel Influences On Physical Activity Participation In Rural And Cancer Populations With Obesity, Nashira Inika Brown Jan 2022

Multilevel Influences On Physical Activity Participation In Rural And Cancer Populations With Obesity, Nashira Inika Brown

All ETDs from UAB

espite the strong evidence of physical activity benefits, the prevalence of physical inactivity and associated obesity continues to increase. Rural and cancer survivor populations with obesity, in particular, remain highly inactive and are at increased risk of comorbidities. Thus, physical activity interventions are needed to promote active lifestyles. However, before developing or adapting existing multi-level physical activity interventions, more research is needed to understand the necessary components to meet the needs and preferences of these unique populations. Therefore, this project involved identifying the gaps in literature followed by three studies to investigate the multilevel influences on physical activity in rural …


The Roles Of Racial Discrimination And Sleep In Cognitive Functioning In Diverse Youth, Queenisha Crichlow Jan 2022

The Roles Of Racial Discrimination And Sleep In Cognitive Functioning In Diverse Youth, Queenisha Crichlow

All ETDs from UAB

Cognitive functioning is an important aspect of human development that is closely related to youth academic outcomes (Caemmerer et al., 2018). Specifically, there is evidence that cognitive abilities such as memory, attention, and self-control are predictive of academic achievement in youth (Peng & Kievit, 2020). Current research suggests that chronic stress reduces cognitive functioning (Korten et al., 2014), but few studies have examined this relationship for race-related stress, specifically racial discrimination. Considering that racial discrimination is a common and reoccurring type of stress in the lives of minority youth (Hughes et al., 2016), it is possible that chronic exposure to …

Smoking And Perceived Stress: Examining The Impact Of Racial Identity And Risk For Obstructive Sleep Apnea Through A Moderated Mediation Model, Sofia Mildrum Chana

All ETDs from UAB

Background: Cigarette smoking is known to have a negative effect on individuals’ sleep quality, and symptoms of insomnia. Smoking can particularly exacerbate sleep disorders such as obstructive sleep apnea (OSA) by increasing irritation and inflammation of the upper respiratory conducts. Previous research highlights the complex positive association between cigarette smoking and perceived stress. Sleep may be an important aspect intervening in the association between smoking and perceived stress, given that individuals who report high stress also report worse sleep quality and are at greater risk for OSA. However, limited research has examined the indirect association of cigarette smoking and perceived …

Life-Space Mobility In The Older Adult, Community-Dwelling Cancer Survivor In The Deep South: A Secondary Data Analysis, Richard A. Taylor

All ETDs from UAB

By 2040, the U.S. is projected to have 26.1 million cancer survivors; 73% of these will be over 65 years old. Much is known about life-space mobility (LSM) in patients with non-cancer serious illnesses. Restricted LSM affects every aspect of an older adult’s life; their independence, autonomy, and quality of life (QOL). To date, there are no studies examining LSM in older cancer survivors. Therefore, we examined LSM, factors that affect LSM, and the relationship between LSM and QOL in older cancer survivors using existing data from the University of Alabama at Birmingham (UAB) Study of Aging (SOA) (NIA AG15062). …

The Relationship Between Nurse And Therapy Staffing Levels And The Medicare Patient-Driven Payment Model Reimbursement During The Covid-19 Pandemic, Roland T. Shapley

All ETDs from UAB

The Patient Driven Payment Model (PDPM) brought about a paradigm shift in the way skilled nursing facilities are reimbursed, by linking complexity of care to beneficiary need, expanding case-mix adjusted components by including a non-therapy ancillary and speech language pathology component, and limiting the volume of therapy services provided. The COVID-19 pandemic wreaked havoc upon the nursing home industry that gave rise to high patient and staff infections and fatalities, declining occupancy rates, and nursing shortages, compelling the Department of Health and Human Services to provide $4.9 billion in CARES Funding to skilled nursing facilities (SNFs). Using Payroll Based Journal, …

Characterization Of The Metabolic And Cognitive Features Of A Novel Alzheimer’S Disease Rat Model Along With Investigation Of Its Gut Microbiota Change Over Time, Akash Nagarajan

All ETDs from UAB

Alzheimer’s disease (AD) is currently the fifth highest cause of death in the United States and affects primarily individuals of very old age (>80 yrs.). Aging is known to be the biggest risk factor of AD. Recent studies have shown that AD patients have an altered gut microbiota composition. To investigate whether the Alzheimer’s disease pathology in the brain could drive gut microbiota changes during the adult and late life stage of the rat, we performed 16S ribosomal RNA sequencing on the fecal samples of the animals at 14 months and 20 months of age. We found a distinctive …


Self-Awareness Of Functional Deficits In Older Adults With Mild Cognitive Impairment, Kayla Ann Steward Jan 2020

Self-Awareness Of Functional Deficits In Older Adults With Mild Cognitive Impairment, Kayla Ann Steward

All ETDs from UAB

Performance of instrumental activities of daily living (IADLs) can become compromised in older adults with mild cognitive impairment (MCI). Poor self-awareness of deficits, also known as anosognosia, occurs in a substantial minority of those with MCI and varies in extent depending on the domain examined. This dissertation attempts to explain the inter- and intra-patient variability in anosognosia by examining (1) differences in objective IADL performance and self-awareness of functional difficulties between those with amnestic single- (-ASD) and multi-domain (-AMD) MCI, and by examining (2) the neuropsychological and (3) neuroanatomical correlates of anosognosia for IADLs in older adults across a broad …


Mitochondrial Priming Of Tumor Initiating Cells Involves Repression Of Mitochondrial Fission Activity Towards Redox Regulation Of The Cell Cycle Regulator Cyclin E, Brian Spurlock Jan 2020

Mitochondrial Priming Of Tumor Initiating Cells Involves Repression Of Mitochondrial Fission Activity Towards Redox Regulation Of The Cell Cycle Regulator Cyclin E, Brian Spurlock

All ETDs from UAB

Mitochondrial dynamics primarily refers to the opposing fission or fusion events between individual mitochondria, which maintains steady-state mitochondrial morphology in cells. Fission and fusion activities maintain the energetics of normal and neoplastic stem cells. We developed the novel approach mito-SinCe2 to study the bidirectional relationship between mitochondrial dynamics and energetics. Application of this method led to the hypothesis that mitochondria-dependent ovarian tumor initiating cells interconvert between 3 states with distinct mitochondrial energetics/dynamics relationships. Cells in one state, characterized by high mitochondrial ROS and low fission activity, appear to be primed for self-renewal by mitochondria. We call these cells mitochondria-primed stem …

Social Support And Self-Care Efficacy As Mediators Of Racial Disparities In Diabetes Health In Older Adults, Wesley Browning

All ETDs from UAB

Diabetes is a health problem that affects millions of Americans annually, and Black Americans have a higher prevalence with more complications than White Americans. A disparity exists between Black and White older adults living with diabetes in distress related to symptoms, treatment, and complications associated with the disease. Additionally, there are differences in levels of performing diabetes self-care behaviors between Blacks and Whites. One series of factors that may predict better diabetes self-care and diabetes distress in older adults are self-care efficacy and components of social support. This study used linear regression models to predict racial differences between Blacks and …
