Hospital Charge And Ricing Transparency, Kunal N. Patel Jan 2020

Hospital Charge And Ricing Transparency, Kunal N. Patel

All ETDs from UAB

Hospital pricing is not uniformly disclosed to patients up-front before the delivery of healthcare. Moreover, pricing is not commonly understood by consumers and researchers, because the information was largely unavailable due to the lack of a federal policy mandate to make the information publicly available up until recently. The federal government instituted a series of regulations that initially began to take effect in 2019 in order to increase hospital pricing transparency with the aim of bending the healthcare cost curve. In this dissertation, hospital response, hospital standard charge variation, and healthcare management and policy expert opinion surrounding the implementation of …


Challenges And Promising Strategies For Maximizing Pregnant Women's Adherence And Retention In Niv Care In The Context Of Option B+ In Kenya, Anna Helova Jan 2020

Challenges And Promising Strategies For Maximizing Pregnant Women's Adherence And Retention In Niv Care In The Context Of Option B+ In Kenya, Anna Helova

All ETDs from UAB

Under the current Kenyan guidelines, pregnant/postpartum women who test HIV-positive are immediately put on the lifelong antiretroviral (ART) therapy (Option B+) and are initiated into the prevention of mother-to-child (PMTCT) protocol. Gaps at each step of the PMTCT continuum undermine the positive impact of lifelong ART. Challenges at the individual, interpersonal, community, and health facility-levels contribute to these gaps. A community-based mentor mother (cMM) program tested under the Mother-Infant Visit Adherence and Treatment Engagement(MOTIVATE!) Trial (NICHD R01 R01HD080477; ClinicalTrials.gov#14-0331) is a potential approach to address these challenges. The three manuscripts comprising this dissertation used qualitative and quantitative methods with the …


Impact Of Registered Nurse Staffing Ratio On Nursing Home Operating Margins And Quality Measure Star Ratings, Douglas R. Whitman Jan 2020

Impact Of Registered Nurse Staffing Ratio On Nursing Home Operating Margins And Quality Measure Star Ratings, Douglas R. Whitman

All ETDs from UAB

Today’s nursing homes are under immense pressure from government regulators to improve quality while the government simultaneously tightens reimbursement rates. These two forces squeeze operating margins. The question facing nursing home operators is how to improve quality without breaking the bank. This study looks at the association of more registered nurses (RN) with quality and margins in U.S. nursing homes. This research project fills literature gaps which previously found improved nursing home quality correlates with more RNs. However, prior studies used self-reported data and typically considered only two or three quality measures. This study uses recently released electronic payroll data …

All ETDs from UAB

Antimicrobial stewardship programs are becoming more widespread to combat antibiotic resistance. This study aimed to evaluate the influence of patient-level characteristics on fluoroquinolone susceptibly among five gram-negative isolates to help better their implementation. We performed a retrospective analysis of patients over the age of 18 for five gram-negative isolates (Acinetobacter species, Enterobacter cloacae, Escherichia coli, Klebsiella pneumoniae, and Pseudomonas aeruginosa). We utilized Cox proportional hazards to determine the risk of patient-level characteristics, for both hospital and community-acquired infections, on fluoroquinolone resistance between 2016 and 2019. The population sample consisted of 8,285 patients receiving fluoroquinolones for at least one of the …


Locus Coeruleus Degeneration In Alzheimer’S Disease And Its Effect On Beta-Adrenergic Signaling In The Hippocampus, Bethany Langner Jan 2020

Locus Coeruleus Degeneration In Alzheimer’S Disease And Its Effect On Beta-Adrenergic Signaling In The Hippocampus, Bethany Langner

All ETDs from UAB

Locus coeruleus (LC) degeneration in Alzheimer’s Disease (AD) and loss of noradrenergic (NA) innervation in hippocampus contributes to learning and memory deficits. Recently, a novel rat model (TgF344-AD) has been created that allows for a more thorough investigation into these mechanisms due to its similarity to human AD pathology. The McMahon lab has recently demonstrated heightened long-term potentiation (LTP) and a ‘supersensitivity’ of -adrenergic receptors (-ARs) at excitatory synapses in the dentate gyrus (DG) in TgF344-AD rats. These mechanisms could be responsible for maintaining learning and memory during buildup of AD pathology. The first goal of this Master’s thesis was …

The Relationship Between Asthma And Electronic Cigarette Use Among Youth And Young Adults: Mediation And Moderation Approaches, Abdullah M M Alanazi

All ETDs from UAB

Asthma is associated with a higher likelihood of electronic cigarette (e-cigarette) use, which may increase the risk of pulmonary complications. Therefore, we sought to identify factors that influence e-cigarette use that may inform future behavior interventions targeting e-cigarette use prevention. In this dissertation, we used mediation and moderation to model the relationship of health beliefs, psychosocial and behavioral factors that may affect the relationship between e-cigarette use and asthma. We used national samples from public datasets, and a clinical sample recruited from healthcare facilities in Alabama. The results of this study are reported in three different papers. In the first …

The majority of HCoVs are emerging human pathogens with 7 known types causing human disease and 5 being identified in the last 2 decades. Methods: We performed a retrospective review of all encounters with known HCoV at a tertiary pediatric hospital from January 2015 until January 2018. Electronic medical records (EMRs) were reviewed for demographic data, HCoV type, viral copathogens, time to testing, admission, need for increased intensity of care (HLC), requirement for supplemental oxygen, radiographic findings suggestive lower respiratory tract disease (LRT) when available …


Marginalized Models With Heterogeneous Random Effects For Zero-Inflated Longitudinal Count Data, Steve Boateng Ampah Jan 2020

Marginalized Models With Heterogeneous Random Effects For Zero-Inflated Longitudinal Count Data, Steve Boateng Ampah

All ETDs from UAB

Longitudinal count data sometimes called panel data come up most often in publichealth and biomedical research, where investigators are interested in assessing the association between an identified exposure and the correlated count outcomes. It is worth mentioning most of these correlated count data exhibit over-dispersion, excess zeros and heterogeneous properties which when ignored during analysis can lead to biased estimates of covariate effects. The traditional zero-inflated count models with random effects have been developed to analyze such correlated count data, however the two sets of regression coefficients from this model, directly allow subgroup interpretations with the first set of coefficients …


The Role Of Neutrophils In Chronic Heart Failure, Sergey Antipenko Jan 2020

The Role Of Neutrophils In Chronic Heart Failure, Sergey Antipenko

All ETDs from UAB

Acute myocardial infarction (MI) produces massive, sudden cardiomyocyte death, triggering an inflammatory and healing response that initially leads to scar formation and ultimately may induce progressive ischemic cardiomyopathy and heart failure (HF). Scar formation and left ventricular (LV) hypertrophy occur in response to MI to stabilize injury compensating for lost myocardial function. Over time, heart function can become decompensated due to neuroendocrine dysfunction and adverse LV remodeling, ultimately leading to HF. Adverse remodeling is characterized by continued dysregulated collagen deposition, cardiomyocyte hypertrophy, and increased inflammation. Studies have documented a resurgence in inflammatory cytokines and infiltrating leukocytes after resolution of the …


Molecular Regulation Of Glioblastoma Spatial Heterogeneity And Therapeutic Resistance, Soniya Bastola Jan 2020

Molecular Regulation Of Glioblastoma Spatial Heterogeneity And Therapeutic Resistance, Soniya Bastola

All ETDs from UAB

Glioblastoma multiforme (GBM) is a highly invasive, highly vascularized, and heterogeneous malignant tumor of the brain. Due to the highly infiltrative phenotype of GBM, surgery often leaves behind residual tumor cells. In many cases, recurrence occurs close to the surgical margin suggesting the role of these remaining cells in promoting tumor aggressiveness. Rapidly growing tumor creates subsequent hypoxic, and hypovascular core due to limited nutrients, whereas tumor cells in the leading edge have access to nutrients from vasculature enriched microenvironment. Studies have identified the cellular and molecular heterogeneity between the tumors in core and edge. Still, their mechanisms of intercellular …


Rab27 And 14-3-3 Mediated Regulation Of Alpha-Synuclein Pathology, Rachel Nicole Underwood Jan 2020

Rab27 And 14-3-3 Mediated Regulation Of Alpha-Synuclein Pathology, Rachel Nicole Underwood

All ETDs from UAB

Alpha-synuclein (αsyn) is the key component of proteinaceous aggregates termed Lewy Bodies (LBs) that pathologically define a group of disorders known as synucleinopathies, including Parkinson’s Disease (PD) and Dementia with Lewy Bodies (DLB). αSyn is thought to misfold and spread throughout the brain in a prion-like fashion. Transmission of αsyn necessitates the release of misfolded αsyn from one cell and the uptake of that αsyn by another, in which it templates the misfolding of endogenous αsyn. Identifying regulators of this process is essential to understanding how αsyn propagates and furthers disease progression. In this study, we investigated Rab27 and 14-3-3θ …


Tau-Dependent Regulation Of Network Hyperexcitability By Alzheimer’S Disease Risk Gene Bin1, Yuliya Voskobiynyk Jan 2020

Tau-Dependent Regulation Of Network Hyperexcitability By Alzheimer’S Disease Risk Gene Bin1, Yuliya Voskobiynyk

All ETDs from UAB

Alzheimer’s disease (AD) is the leading neurodegenerative disorder that affects an astonishing 5.8 million Americans, a number projected to reach 14 million by the year 2050. While only about 1% of all AD cases are caused by mutations in APP, PSEN1, and PSEN2, the cause of sporadic AD remains unknown. Variations in several risk genes have been proposed to contribute to the development of sporadic AD cases. Since, currently, there are no disease-modifying therapies for families affected by AD and multiple anti-amyloid-beta therapies failed in clinical trials, determining how these risk genes contribute to the development of AD is crucial …


The Mir-23a Cluster Controls An Epigenetic Axis In Osteoblast Development During Bone Formation, Benjamin J. Wildman Jan 2020

The Mir-23a Cluster Controls An Epigenetic Axis In Osteoblast Development During Bone Formation, Benjamin J. Wildman

All ETDs from UAB

Differentiation of pre-osteoblasts is critical to controlling in-vivo development and growth of bone. Recent studies highlight the importance of epigenetic regulation in directing osteoblast commitment and function. Here we show that the microRNA-23a cluster (miR-23a, 27a, and 24-2) controls bone mass in-vivo through a previously unknown epigenetic mechanism. MiR-23a cluster knockdown increased the intensity of Alkaline Phosphatase staining in MC3T3-E1 cells. Additionally, it upregulated mRNA expression of osteogenic marker genes such as Runx2 and Osteocalcin. Micro-CT analysis of 2-month and 6-month femurs showed that trabecular bone volume and trabecular number significantly increased in miR-23aClZIP mice as compared to controls. Histological …

All ETDs from UAB

GENE–ENVIRONMENT INTERACTION IN PARKINSON DISEASE: THE GUT MICROBIOME ZACHARY D. WALLEN GENETICS, GENOMICS, AND BIOINFORMATICS ABSTRACTParkinson disease (PD) is a progressive neurodegenerative disease with no cure. Majority of cases are idiopathic, and the cause is unknown. Studies have been conducted in human and animals to identify PD risk factors, resulting in a list of genetic and environmental factors that modestly increases risk of PD. Still, no individual risk factor fully explains the cause of PD, and neither has the combination of these factors. Additional avenues of research are being investigated to find potential triggers of PD, and factors that might …


T Cells In Synucleinopathies, Gregory Paul Williams Jan 2020

T Cells In Synucleinopathies, Gregory Paul Williams

All ETDs from UAB

Synucleinopathies, which include Parkinson disease (PD), dementia with Lewy Bodies (DLB), and multiple system atrophy (MSA), are a collection of neurodegenerative diseases that are in major part defined by the presence of alpha-synuclein (α-syn) rich protein aggregates in the brain. Increasing evidence has highlighted a neuroinflammatory phenotype also associated with these synucleinopathies. This neuroinflammatory phenotype includes the activation of central nervous system (CNS) microglia, increased pro-inflammatory cytokines, and the infiltration of peripheral T cells into the CNS. We sought to further explore the T cell responses associated with PD and MSA. Using two preclinical mouse models of PD and MSA, …


Race, Type Ii Diabetes Mellitus And Vertebral Fragility Fractures: A Cross-Sectional Analysis From Nhanes, Yuchen At Xiao Jan 2020

Race, Type Ii Diabetes Mellitus And Vertebral Fragility Fractures: A Cross-Sectional Analysis From Nhanes, Yuchen At Xiao

All ETDs from UAB

IntroductionThis study examined the association between race and bone health, and if T2DM modifies this association in a diverse sample of adults. Methods We conducted a cross-sectional study using the 2013-2014 National Health and Nutrition Examine Survey (NHANES) data. Bone health outcomes included lumbar spine BMD (lowered BMD based on T-scores <-1), and vertebral deformities, assessed via vertebral fracture assessment (VFA), including presence, number of deformities, and severity ratio of deformities. T2DM status and other demographic, lifestyle, and health characteristics were self-reported via questionnaire data. To assess if T2DM modifies the association between race and bone health outcomes, we conducted stratified analyses using logistic regression for dichotomous outcomes, Poison regression for count outcomes, and linear regression for continuous outcomes. Results Non-Hispanic (NH) Blacks have significantly less odds of being lowered BMD and osteoporosis comparing to NH-Whites in the crude model and significantly less odds of having vertebral deformities comparing to NH-White in both crude and adjusted model for non-diabetic participants. Such differences are not observed in diabetic groups. Participants in Other race group have significantly more odds of being lowered BMD comparing to NH-Whites in the adjusted model for both diabetic and non-diabetic groups. And have significantly more odds of having vertebral deformities in the diabetic group, crude and adjusted, yet the differences are not significant in non-diabetic groups. Similar results were seen in the number of deformities and total bone loss ratio. The potential modification effect of T2DM was not significant in these models. Conclusions In our national evaluation, bone health differs not only by race and ethnic group but also by T2DM status. The protective vertebral fragility effects observed among NH-Blacks was no longer present among those with diabetes. Likewise, among participants in other racial and ethnic groups, T2DM seemed to magnify the association of worse vertebral fragility. Such trends indicate a potential modifying effect of participants’ T2DM status and should be noted clinically, yet more studies are required for more precise results.

Human cytomegalovirus (HCMV) is a ubiquitous pathogen that infects over 50% of the world’s population. HCMV infection is asymptomatic in healthy individuals, however can cause severe morbidity and mortality in individuals with compromised innate or adaptive immunity. As a complex virus that has been known for about 70 years, we are still in search of vaccines or effective treatments against it. HCMV genome encodes over 175 open reading frames with the function of majority proteins remains to be defined. A unique feature of HCMV among herpesvirus is the reorganization of cellular secretory pathway and membranes to form assembly compartment (AC). …


Co-Factors In Fgf Signaling, Christopher Yanucil Jan 2020

Co-Factors In Fgf Signaling, Christopher Yanucil

All ETDs from UAB

The fibroblast growth factor (FGF) family consists of a group of proteins whose diverse biological functions are mediated by receptor tyrosine kinases, termed FGF receptors (FGFR) 1-4. While paracrine FGFs require heparin sulfate as a co-factor for FGFR bind-ing and signaling, it has been assumed that endocrine FGFs, such as FGF23, do not bind heparin but instead require klotho, a family of transmembrane proteins, as a co-receptor on specific target cells. FGF23 acts as bone-derived hormone that targets tubular epitheli-al cells in the kidney via FGFR1 and α-klotho to reduce renal phosphate uptake. In chron-ic kidney disease (CKD), the kidney …

Network-Based Analytics For Discovering Gene Modules And Biomarkers In Complex Diseases, Zongliang Yue

All ETDs from UAB

With rapidly increasing novel discoveries of associations between genomic data and complex disease phenotypes, the translation of those associations into knowledge and the identification of critical molecular mechanisms are essential to guild clinical decisions such as the diagnosis of symptomatic individuals, the prediction of disease risk, reproductive genetic counseling, and determining pharmacogenetic profiles for treatment. To decipher the genome of complex diseases, gene-centric analyses focus on detecting molecular mechanisms lead by driver genetics variants, abnormally expressed genes and high-abundance proteins through gene module construction. Additionally, the gene module construction approaches implement systems biology analysis to reveal the causative co-expressed gene …


Exploring The Mechanism Of Cleavage And Secretion Of The Major Sperm Protein (Msp) Domain Of The Vapb/Vpr-1 Protein, Hala Zein-Sabatto Jan 2020

Exploring The Mechanism Of Cleavage And Secretion Of The Major Sperm Protein (Msp) Domain Of The Vapb/Vpr-1 Protein, Hala Zein-Sabatto

All ETDs from UAB

VAPB is one of three mammalian VAP proteins. It is a type-II ER transmembrane protein whose N-terminal major sperm protein domain (MSPd) is cleaved and secreted. Since the MSPd faces the cytosol, rather than the ER lumen, how it is cleaved and secreted is not yet known. In humans, P56S is a substitution mutation within the VAPB protein that segregates with cases of familial Amyotrophic Lateral Sclerosis (ALS) and prevents the secretion of VAPB MSPd. The work described in this thesis uses C. elegans to study how the N-terminal MSPd of VAPB is proteolytically processed, secreted, and regulated. C. elegans …


Circadian Control Of Blood Pressure And Renal Electrolyte Excretion, Dingguo Zhang Jan 2020

Circadian Control Of Blood Pressure And Renal Electrolyte Excretion, Dingguo Zhang

All ETDs from UAB

Many physiological processes, including blood pressure (BP) regulation, follow specific rhythms tied to a 24-h cycle. This is largely because circadian genes operate in virtually every cell type in the body. In healthy individuals, BP during nighttime is 10-20% lower compared to daytime, a phenomenon known as “nocturnal dipping”. It is acknowledged that the dipping of BP is essential in maintaining normal cardiovascular and renal function. However, it remains unclear as to what factors contribute to nocturnal dipping. The purpose of this dissertation is to elucidate mechanisms underlying the circadian rhythm of BP. Bmal1 is one of the core circadian …

Toward The Mechanism Underlying Latanoprost- And Benzalkonium Chloride-Induced Meibomian Gland Dysfunction In Patients Treated For Glaucoma, Jillian Ziemanski

All ETDs from UAB

Once thought to be no more than a vexing eye condition, ocular surface disease (OSD) is now being viewed as a differentiating factor between sight and no sight. In the setting of glaucoma, OSD can interfere with treatment success, potentially allowing the visually devastating pathology of glaucoma to plow onward with little restraint. Compounding the clinical challenge is the growing awareness that glaucoma-associated OSD appears to be iatrogenically induced by topical ophthalmic medications. Daily, topical instillation of preserved prostaglandin analogs (PGAs), the most common first-line treatment for glaucoma, has been linked to a variety of OSD subtypes, including meibomian gland …

Lim Transcriptional Complexes That Impact Endocrine Pancreas Development And Function, Maigen Bethea

All ETDs from UAB

The Ldb1:Isl1 LIM transcriptional complex is critical for endocrine pancreas development as well as b-cell terminal differentiation. These complexes have been shown to interact with various proteins to elicit transcriptional regulation in other tissues, yet few interactors have been identified in b-cells. Therefore, the objective of this dissertation was to identify interactors of Ldb1 and Isl1 and assess their contributions to endocrine pancreas development and function. Using a reversible crosslink immunoprecipitation (ReCLIP) and mass spectrometry (MS) strategy to isolate endogenous Ldb1 and/or Isl1 interacting protiens, SSBP3, Rnf20, and Rnf40 (E3 ubiquitin ligases) coregulators were identified. SSBP3 was found to interact …


Transcriptional, Translational, And Enzymatic Metabolic Regulation By L-2 Hyroxyglutarate, Garrett Brinkley Jan 2020

Transcriptional, Translational, And Enzymatic Metabolic Regulation By L-2 Hyroxyglutarate, Garrett Brinkley

All ETDs from UAB

Recent studies have identified elevated levels of a small metabolite, L-2 Hydroxyglutare (L-2HG), which curiously has no known metabolic roles. Renal tumors, hypoxia as well as larval development, specifically in Drosophila, all have been identified to have high levels of L-2HG. These broad categories suggest L-2HG has a physiological role. This work uncovers the impact of elevated levels of L-2HG in altering normal kidney and renal tumors. With structural similarity to α-Ketoglutarate (αKG), L-2HG acts as a competitive inhibitor to enzymes that utilize αKG as substrates or co-factors. L-2HG is known to be metabolized by L-2HG dehydrogenase (L2HGDH). Loss of …

Epigenetic Regulation In Cancer And Development, Theodore Busby

All ETDs from UAB

Feedback loops between cellular cues and changes in gene expression mediate the interactions between a multitude of regulatory events that promote development and cancer. Vesicular trafficking is an important process in carrying out signaling events by transporting receptors and ligands to and from the cell surface. GBF1 and BIG1 are large guanine-exchange factors (GEFs) that activate GTPase mediated shuttling of cargo through the Golgi apparatus. This dissertation demonstrates that GBF1 localizes to the cytoplasmic membrane in glioblastoma multiform cells to maintain cell shape and promote migration. Reports have shown that BIG1translocates to the nucleus is hepatocyte carcinoma cell lines in …


Restless Legs Syndrome And Multiple Sclerosis: The Possible Role Of Physical Activity For Managing Symptoms, Katie Cederberg Jan 2020

Restless Legs Syndrome And Multiple Sclerosis: The Possible Role Of Physical Activity For Managing Symptoms, Katie Cederberg

All ETDs from UAB

Restless legs syndrome (RLS) is an idiopathic neurological disorder characterized by unpleasant sensations in the legs that affects 26% of persons with multiple sclerosis (MS). The current pharmacological treatments for RLS are associated with a number of side effects, including the worsening of symptoms (i.e., augmentation). Physical activity represents a promising, behavioral approach for managing symptoms of RLS in MS. To date, physical activity has demonstrated tremendous benefits for managing many consequences of MS, but there is no evidence on its efficacy for managing RLS in MS. This dissertation described the current literature regarding physical activity and RLS in adults …


Abnormalities In The Akt-Mtor Signaling Pathway In The Dorsolateral Prefrontal Cortex In Schizophrenia, Radhika Chadha Jan 2020

Abnormalities In The Akt-Mtor Signaling Pathway In The Dorsolateral Prefrontal Cortex In Schizophrenia, Radhika Chadha

All ETDs from UAB

Schizophrenia (SZ) is a complex and heterogeneous mental illness in which myriad changes across multiple neurotransmitter systems (dopamine, serotonin, GABA, glutamate, and others) have been reported. Numerous regulatory mechanisms have been explored in SZ research and rather than being a disorder of one specific neurotransmitter pathway, SZ may instead be a disturbance of intracellular signaling processes that underlie the regulation of these systems. The AKT-mTOR signaling cascade plays an important role in core cellular processes of cell growth, metabolism and survival and is one such potential candidate. Abnormalities in AKT expression and activity have been consistently implicated in SZ pathophysiology …
