Hiv Disclosure, Retention In Hiv Care, And Viral Load Suppression : A Study Among New To Hiv Care Patients, Riddhi Modi
Hiv Disclosure, Retention In Hiv Care, And Viral Load Suppression : A Study Among New To Hiv Care Patients, Riddhi Modi
All ETDs from UAB
HIV remains a major ongoing public health problem globally and in the United States (US). Despite the advances in the antiretroviral therapy (ART), new HIV cases continue to occur. Hence, understanding the factors that influence patient’s decision to HIV treatment and prevention is of paramount. HIV disclosure, an important modifiable behavior, is a barrier to linkage and engagement in HIV care. Thus far, studies examining HIV disclosure and its impact on HIV related outcomes, retention in care (RIC) and viral load (VL) suppression among HIV patients newly initiating care are scant. While these studies provide insights on risk factors of …
Psychological Well-Being And Smoking Cessation, Christopher Thorne
Psychological Well-Being And Smoking Cessation, Christopher Thorne
All ETDs from UAB
Introduction: The substantial death toll from smoking combined with the low success rates of current treatment approaches warrants further investigation into mechanisms that promote cessation. While the role of negative affect has been studied extensively in relationship to smoking cessation, the role of psychological well-being (PWB; e.g., life satisfaction, optimism, positive affect, purpose in life, resilience) has received little attention. Treatment outcomes might improve with a better understanding of PWB’s role in smoking cessation. Methods: Relationships between smoking and PWB were examined in three studies. First, using panel data from the biennial, longitudinal Health and Retirement Study, I developed separate …

Pharmacogenetics aims to improve individualized medicine by combining genetic information with clinical data when assigning drug treatments. Different diseases are often associated with different factors, each with its own distributional characteristics. For rare or complex diseases, these characteristics may not be well understood and standard analysis methods may not be appropriate. In psychiatric disorders, for example, multiple drug treatments need to be compared across small sample sizes with heterogeneous patient populations, making implementation of standard methods difficult. Simulating data that mirrors clinical data is important because it allows investigators to determine which method is best suited for data from their …

Elevated Blood Lead Levels, Cancer Incidence, And All-Cause Mortality In Adults, Sherri L. Davidson
All ETDs from UAB
Epidemiologic studies have indicated an association between lead exposure and cancer. Although lead exposure has declined in recent decades, from removal of lead in gasoline and paint, lead exposure remains a health concern from environmental and occupational sources including aging water systems. In a retrospective cohort study, Adult Blood Lead Epidemiology and Surveillance (ABLES) records in Alabama were linked to cancer incidence data in the Alabama Statewide Cancer Registry and mortality data from the Alabama Center for Health Statistics, using a probabilistic linkage program. Blood lead level (BLL) measurements were used to categorize exposure levels. Odds ratios approximated relative risks. …
Heart Failure In A Contemporary Biracial Cohort, Matthew Mefford
Heart Failure In A Contemporary Biracial Cohort, Matthew Mefford
All ETDs from UAB
Heart failure (HF) is the inability of the heart to meet the perfusion needs of the body. HF is a leading contributor to the burden of cardiovascular disease (CVD) and remains a public health concern. Hypertension is a major modifiable risk factor for the prevention and management of HF. Hypertension develops earlier, is less controlled, and has a stronger association with some CVD and renal outcomes among blacks versus whites. These disparities may extend to HF. In addition, adults with HF often have complex treatment regimens due to multimorbidity, making medication adherence an issue. The goal of this dissertation was …

Exploring The Relationship Between Social Support, Pharmacy Access And Medication Adherence, Favel Leah Mondesir
All ETDs from UAB
Barriers of medication adherence exist among people with coronary heart disease (CHD) and CHD risk factors, including, poor social support, poor pharmacy access and other patient, social/economic, therapy, condition, and health-care system/health-care team-related factors. However, there are few data on influence of these factors on medication adherence among people with CHD risk factors other than diabetes. Therefore, this dissertation aimed to investigate associations of medication adherence with social support (n=17,113) and pharmacy access (n=8,250) quantitatively using data from the REasons for Geographic and Racial Differences in Stroke (REGARDS) study (black and white adults with CHD or CHD risk factors ≥45 …

Visual, Attentional, And Cognitive Risk Factors For Motor Vehicle Collision Involvement Among Older Adults, Carrie Huisingh
All ETDs from UAB
Motor vehicle collisions are a major public health problem for older adults in the United States. In 2013, there were 5,671 older adults killed and an estimated 222,000 injured in motor vehicle crashes. After adjusting for miles driven, the risk of crashing increases rapidly after age 70, nearly equal to that of younger drivers whose crash rate is the highest among all age groups. Driving is a highly complex task that relies on a variety of visual and cognitive functions. A large body of work has demonstrated that drivers with visual sensory impairments and/or higher-order visual-cognitive processing deficits, those who …

This study applies Rasch analysis to validate two scales in the Parenting for the First-time project: Beck Depression Inventory (BDI-II) and Parenting Stress Index (PSI). The main purpose of this study is to evaluate quality of the two scales by using Rasch analysis to examine the unidimensionality, reliability, fit statistics, group and time invariance, and optimal response categories. Meanwhile, this study also compares the results of Rasch model and Classical Test Theory (CTT) to assess the advantages of Rasch analysis. Result: Both Rach analysis and CTT show the evidence of unidimensionality of BDI-II in the three administrative periods: Prenatal, 6 …
Immunosuppression And Risk Prediction Of Sepsis Following Solid Organ Transplantation, John Patrick Donnelly
Immunosuppression And Risk Prediction Of Sepsis Following Solid Organ Transplantation, John Patrick Donnelly
All ETDs from UAB
Solid organ transplant (SOT) recipients typically need immunosuppressive therapy (IST) to protect graft function and regimens may include an induction agent (e.g., anti-thymocyte globulin [ATG] or alemtuzumab) with maintenance medications (e.g., tacrolimus, mycophenolate mofetil [MMF], mycophenolic acid [MPA], or azathioprine [AZA]). Sepsis, or organ dysfunction resulting from a dysregulated host response to infection, is a common complication among SOT recipients. Using national data from the United States Renal Data System (USRDS), we sought to determine the associations of IST regimens and maintenance medication exposure with sepsis risks and outcomes among kidney transplant recipients (KTRs). Using USRDS and single center data, …

Psychosocial Job Stress And Oxidative Stress In Emergency Department Nurses, Rupkatha Bardhan
All ETDs from UAB
Job stress often causes work-related physical injuries and chronic exposure to such environment may lead to poor health outcomes. Job stress in recent years has grown significantly within the workforce due to performance pressure, long work hours and poor pay structures. Nurses work in the forefront to save patients’ lives. High job demand in this noble profession often leads to progressive decline in physical and mental health. There are existing reports that nurses in the United States (US) suffer from “burnout” syndrome which may also negatively affect patient care. There are very few studies that measured work-related stress in nurses …

All ETDs from UAB
ASSESSING THE COMPARATIVE EFFECT OF TOCILIZUMAB ON RISK OF CARDIOVASCULAR DISEASE AMONG RHEUMATOID ARTHRITIS PATIENTS USING CLAIMS DATA: A DIRECT COMPARISON AMONG BIOLOGIC DISEASEMODIFYING ANTIRHEUMATIC DRUGS FENGLONG XIE PhD-EPID ABSTRACT Tocilizumab is a humanized monoclonal anti-body against the interleukin-6 receptor and is effective in the treatment of rheumatoid arthritis (RA) [1]. Multiple studies have observed unfavorable changes in the lipid profile of tocilizumab-treated RA patients. Few studies have compared the cardiovascular disease (CVD) risk associated with tocilizumab to other biologic disease-modifying antirheumatic drugs (bDMARDS). Due to limitations in existing studies, the real-world association of tocilizumab with CVD risk remains uncertain. …
Assessment Of A Peer Mentoring Program At Lawson State Community College, Teneasha Washington
Assessment Of A Peer Mentoring Program At Lawson State Community College, Teneasha Washington
All ETDs from UAB
ABSTRACT Colleges and universities have begun implementing mentoring programs to offset rising attrition rates; however, the literature on the benefits of these programs is limited particularly among community colleges with peer mentoring programs serving minority students. Further limiting our understanding of post-secondary peer mentoring programs is the lack of research on mentor’s as well as mentee’s perspectives on the mentoring experience. As mentors and mentees serve in a variety of capacities within the mentoring program, it is often difficult to identify outcomes that can be assessed within the mentoring program. Although the success of peer mentoring programs is directly affected …
Assessing Barriers And Facilitators To Appropriate Care For Chronic Pain And Prescription Opioid Abuse, Allyson Varley
Assessing Barriers And Facilitators To Appropriate Care For Chronic Pain And Prescription Opioid Abuse, Allyson Varley
All ETDs from UAB
The objective of this study was to understand and assess barriers and facilitators to the uptake of appropriate care for co-occurring chronic noncancer pain (CNCP) and opioid use disorder. Rates of CNCP and opioid overdose have doubled in the past decade. When a patient transitions from appropriate use to misuse, significant changes must be made to their treatment plan. Considering most CNCP is treated with opioids in the primary care setting, primary care providers (PCPs) are potential change agents to remediate the epidemic of opioid abuse. Although studies have explored opioid stewardship, we still lack an understanding of the factors …
