Subdural Hematoma As A Consequence Of Epidural Anesthesia., Tracy M Bishop Do, Kareem S. Elsayed Ms, Kathleen E. Kane Md
Department of Emergency Medicine
Regional spinal and epidural anesthesia are used commonly in operative procedures. While the most frequent complication, postdural puncture headache (PDPH), is a clinically diagnosed positional headache that is usually self-limited, subdural hemorrhage (SDH) is a potentially fatal complication that cannot be missed. We report a case of an otherwise healthy female who presented with persistent positional headache and was ultimately found to have a large subdural hematoma with midline shift requiring surgical evacuation.

Drive-By Bridge Damage Inspection, Ahmed Ali Elhattab
Drive-By Bridge Damage Inspection, Ahmed Ali Elhattab
All ETDs from UAB
Bridge structures are subjected to continuous degradation due to environmental effects and increase in traffic loading. Bridge monitoring is a key element of any maintenance strategy as it can provide early signs of structural deterioration. In recent years, the demand towards sensor-based bridge monitoring in lieu of visual inspection, has increased. However, sensor-based monitoring is costly and requires significant maintenance. Recent studies on bridge damage monitoring have focused on the instrumentation of a passing vehicle instead of the bridge. This approach is referred to ‘drive-by’ bridge inspection (Kim and Kawatani, 2009). Using this approach, the bridge itself is not instrumented, …
Elliptic Equations And Systems With Nonlinear Boundary Conditions, Alzaki Mohmoud Muhammed Fadlallah
Elliptic Equations And Systems With Nonlinear Boundary Conditions, Alzaki Mohmoud Muhammed Fadlallah
All ETDs from UAB
This dissertation presents some results on the solvability of second order elliptic equations with nonlinear boundary conditions at resonance, in which the nonlinear boundary conditions perturbation is not necessarily required to satisfy Landesman- Lazer conditions or the monotonicity assumption. The nonlinearity may be unbounded. The nonlinearity interacts in some sense with the Steklov spectrum. The proofs are based on a priori estimates for possible solutions to a homotopy on suitable trace spaces and topological degree arguments. We will also study solvability of nonlinear second-order elliptic systems of partial differential equations with nonlinear boundary conditions. We study the generalized Steklov-Robin eigensystem …
Phase Transitions Under Nanoconfining Conditions, Reza Farasat
Phase Transitions Under Nanoconfining Conditions, Reza Farasat
All ETDs from UAB
The objective of this dissertation was to study the effects of nanoconfinement on the thermodynamic and kinetic parameters of phase transitions in selected compounds. The compounds were loaded into silica gel nanopores and filled them partially. A model was developed for estimating the fullness of the nanopores as well as the height of the compound layer deposited on the pore walls. A study of the phase transition in NH4Cl confined to the native silica gel nanopores revealed that the heat of transition increases with the increasing the layer height. Also the transition temperature measured on heating and cooling respectively increases …
The Effect Of Thioredoxin-Interacting Protein Induced Microrna-200 Family Members On Pancreatic Beta Cells, Stephen Filios
The Effect Of Thioredoxin-Interacting Protein Induced Microrna-200 Family Members On Pancreatic Beta Cells, Stephen Filios
All ETDs from UAB
Pancreatic beta cells secrete insulin to maintain normal blood glucose levels and allow cells of the body to use glucose. However, in diabetes, there is beta cell dysfunction and pancreatic beta cells undergo programmed cell death leading to inadequate insulin production and secretion. Thioredoxin-Interacting Protein (TXNIP) is a ubiquitously expressed protein, 46 kDa in size, which is an arrestin protein family member. Unique to this member of the arrestin family, however, is its ability to bind to, and reduce, thioredoxin. The TXNIP gene is increased in pancreatic islets more than any other gene in response to high levels of glucose. …
Exercise Adherence Among Pregnant Women: The Roles Of Socioeconomic Status, Attitudes Towards Prenatal Exercise, And Social Support, Lee Anne Flagg
Exercise Adherence Among Pregnant Women: The Roles Of Socioeconomic Status, Attitudes Towards Prenatal Exercise, And Social Support, Lee Anne Flagg
All ETDs from UAB
Drawing on the sociological theories of fundamental causes and social support, it was hypothesized that exercise during pregnancy would be positively associated with both socioeconomic status (SES) and social support for exercise and that the association between SES and exercise levels would be at least partially explained by attitudes towards exercise. It was also hypothesized that there would be a positive interaction between SES and social support for exercise in relation to exercise levels during pregnancy. Cross-sectional observational data was obtained from a survey of pregnant women, predominantly from those accessing prenatal care at Birmingham, AL area obstetric clinics. The …

Characteristics And Behaviors Based On Introduction To Opioids Among Adults In Buprenorphine/Naloxone Treatment, Angela R. Gallien
All ETDs from UAB
Buprenorphine/naloxone (BNT) is a pharmacological treatment for opioid use disorders and is available by prescription in an office-based setting from physicians with specialized training. The purpose of this study was to identify the characteristics and behaviors among adults on BNT with the intent to identify the linear combination of variables that account for the differences based on the origins of opioid use. Four opioid user groups were identified a priori: recreational users (RU); self-treaters (ST); medical users misusing (MUM); and medical users not misusing (MU). The dependent variables were mental health and mood, pain and medical problems, internal or external …

The Role Of The Teacher In Family Involvement: A Multiple Case Study, Terri Garrison
The Role Of The Teacher In Family Involvement: A Multiple Case Study, Terri Garrison
All ETDs from UAB
The purpose of this qualitative multiple case study was to explore the teacher's role in family involvement in preschool classrooms. Family involvement has been a relevant topic for early childhood educators for many years (Hoover-Dempsey & Sandler, 1995). When families are involved in their child's school experience, it has added a positive benefit to the child's development (Chavkin, 2005; Swick, 2004; Marcon, 1999). Regardless of this widely held belief, many families face barriers that prevent involvement from occurring (Gallimore & Goldenberg, 2001; Lamb-Parker, Piotrkowski, Baker, Kessler-Sklar, Clark, & Peay, 2001). This multiple case study was designed to answer the following …

SAFETY CULTURE AND PATIENT HARM EVENTS: A CONTINGENCY THEORY PERSPECTIVE IN THE CONTEXT OF COMPLEX ADAPTIVE SYSTEMS ALFONSO GATMAITAN ADMINISTRATION-HEALTH SERVICES ABSTRACT This study examines the correlation between a Culture of Patient Safety as measured by hospital staff surveys and actual patient harm attributed to hospital performance. It is generally accepted by health care management leaders that the presence of a strong culture of patient safety has become a critical component in reducing patient harm. However, little empirical evidence within multiple hospitals over time exists to support this belief. Healthcare managers can utilize this evidence in formulating patient safety improvement …

A Redescription Of The Cretaceous Marine Turtle Ctenochelys Acris Zangerl, 1953 And A Systematic Revision Of The 'Toxochelyid'-Grade Taxa Using Cladistic Analysis, Andrew Douglas Gentry
All ETDs from UAB
Within this thesis are two separate articles, each representing a distinct chapter. The first chapter is a redescription of the ‘toxochelyid’-grade marine turtle Ctenochelys acris Zangerl, 1953. This redescription, based on several nearly complete specimens from the early Campanian Mooreville Chalk of Alabama, reveals multiple previously undescribed autapomorphic characteristics of this species and contributes significantly to our understanding of ‘toxochelyid’ alpha taxonomy. The second chapter is comprised entirely of the results of multiple cladistic analyses of the ‘toxochelyid’-grade taxa that produce a hypothesized phylogenetic system of classification for this clade. 108 characters from the cranium, carapace, plastron, and appendicular skeleton …

On Fire Or Burnt Out? The Social Psychological Health Of United Methodist Pastors, Philip Gibson
All ETDs from UAB
This study examines the social processes and structures that shape the social psychological health of United Methodist pastors. These individuals play a central role in a religious institution that is in a state of decline in the 21st century United States. In addition, burnout, a state of compromised social psychological health related to work involving relationships, is a salient issue among clergy. Using a qualitative approach based in grounded theory methodology, 31 semi-structured interviews were conducted with current and former United Methodist pastors, including those in a supervisory role within the Church hierarchy. Using grounded theory coding practices, data from …
Kinomic Profiling And Drug Screening Of Three-Dimensional Glioblastoma Microtumors As A Potential Comparative Model To Orthotopic Xenolines, Ashley Nichole Gilbert
Kinomic Profiling And Drug Screening Of Three-Dimensional Glioblastoma Microtumors As A Potential Comparative Model To Orthotopic Xenolines, Ashley Nichole Gilbert
All ETDs from UAB
Glioblastoma multiforme (GBM), the most common form of primary malignant brain cancer in adults, is a devastating disease for which effective treatment has remained elusive for over 75 years. A likely reason for the minimal progress during this time is the lack of accurate preclinical models to represent the patient in vivo environment, causing a disconnect in drug therapy effectiveness between the laboratory and clinic. Our proposed solution to address this disconnect and the issues of traditional preclinical modeling is to use innovative HuBiogel-based MicroTumors as a three-dimensional (3D) drug screening model for GBM. Six subcutaneous patient-derived xenografts (PDXs) prepared …
Role Of Macrophages In The Cardiomyopathy Associated With Obesity And Type 2 Diabetes, Mehak Goel
Role Of Macrophages In The Cardiomyopathy Associated With Obesity And Type 2 Diabetes, Mehak Goel
All ETDs from UAB
Obesity is a state of chronic low-grade systemic inflammation that, along with type 2 diabetes (T2D), increases the risk of developing cardiovascular disease (CVD). Despite the wealth of information on the link between macrophages and cytokines in adipose tissue and peripheral insulin resistance, their role in the pathogenesis of diabetic cardiomyopathy and cardiac diastolic dysfunction is unclear. We hypothesized that activated immune cell mediators, in particular monocytes and macrophages, are fundamental drivers of diet-induced obesity and diabetic cardiomyopathy. Herein, firstly, a diet-induced model of diabetic cardiomyopathy was developed in C57BL/6 mice by feeding a high fat diet (HFD, 45% kcal …
Consequences Of Trps1 Deficiency On Dentinogenesis, Morgan Goss
Consequences Of Trps1 Deficiency On Dentinogenesis, Morgan Goss
All ETDs from UAB
Dentinogenesis is a complex process of dentin formation. It involves differentiation of odontoblasts, the cells that make dentin, and the formation of a unique extracellular matrix, known as dentin. Dentin is ultimately produced through the interaction of collagen fibers, non-collagenous proteins and hydroxyapatite (HA) crystals. Odontoblasts are cranial neural crest (CNC) ectomesenchymal derived cells. Trps1 is a novel transcription factor believed to play an important role in both tooth formation and the mineralization process. TRPS1 gene mutations are known to result in dental and skeletal abnormalities manifested in humans as tricho-rhino-phalangeal syndrome (TRPS) and Ambras syndrome. Trps1 expression varies throughout …
Unmanned Ground Vehicle Terrain/Road Mobility Foundation And Its Algorithmic Formalization For Wheel Power Management To Improve Leader And Follower Capabilities, Jeremy P. Gray
All ETDs from UAB
The implementation of the autonomy-enabled technologies to improve soldier safety and battlefield distribution for the Ground Distribution fleet, by using semi-autonomous leader and follower capabilities, has begun. The need for tactical and operational mobility and agility is a key element in this process. Their success significantly depends on mobility of the convoy vehicles in terrain and road conditions. Although, existing methods have successfully improved vehicle mobility, those methods have exhausted their potential. There is a need for a new technological paradigm that would lead to a breakthrough in vehicle and convoy mobility research and engineering. Mobility strongly depends on the …
County-Level Homicide In The United States: An Analysis From A Social Disorganization Perspective, Julien Grayer
County-Level Homicide In The United States: An Analysis From A Social Disorganization Perspective, Julien Grayer
All ETDs from UAB
The United States has the highest rates of homicide among industrialized nations. The analysis of variations in the homicide rate lends itself to interpretation through various theoretical frameworks, one of which is social disorganization. Social disorganization is commonly used as a means to discuss crime in the context of neighborhoods and communities. The argument of social disorganization is that criminal activity is curbed by collective efficacy. That collective efficacy is affected by structural variables such as poverty, residential stability, and heterogeneity. The question then became whether social disorganization could be utilized for county-level analysis. The results showed that social disorganization …

The Effect Of Applied Stress On Knowledge Retention In A Multiwall Virtual Environment, David Wayne Brown
All ETDs from UAB
While the science of medicine continues to grow as new discoveries in the treatment of disease are made, the education of existing procedures has not evolved with the growth of new technology. The training of doctors and nurses is still, primarily, one of classrooms and presentations. In addition, this training is predominately focused on treating the patient once they have reached the hospital, with limited thought given to out of hospital emergencies. Simulation labs are present at most schools, but these are limited in their ability to deliver identical scenarios across the entire student population due to variances in personnel …

Lab-On-A-Brane: A Novel Physiologically Relevant Planar Arterial Model To Study Transendothelial Transport, Karim I. Budhwani
All ETDs from UAB
The tremendous quality of life impact notwithstanding, cardiovascular diseases and Cancer add up to over US$ 700bn each year in financial costs alone. Aging and population growth are expected to further expand the problem space while drug research and development remain expensive. However, preclinical costs can be substantially mitigated by substituting animal models with in vitro devices that accurately model human cardiovascular transport. Here we present a novel physiologically relevant lab-on-a-brane that simulates in vivo pressure, flow, strain, and shear waveforms associated with normal and pathological conditions in large and small blood vessels for studying molecular transport across the endothelial …

The Adaptive Significance Of Phenotypic Plasticity In The Wild: An Experimental Test Using The Brown Anole Lizard (Anolis Sagrei), Corey Dale Cates
The Adaptive Significance Of Phenotypic Plasticity In The Wild: An Experimental Test Using The Brown Anole Lizard (Anolis Sagrei), Corey Dale Cates
All ETDs from UAB
The conditions that embryos experience during development have substantial effects on offspring phenotypes and fitness. Although plastic responses to developmental environments are widespread, whether they are adaptive is unknown in most cases. Developmental plasticity is often thought to be adaptive in heterogeneous environments, but it can also enhance fitness when environments experienced by embryos provide cues for the conditions they will eventually experience later in life. Under the latter scenario, early embryonic conditions could program an individual’s physiology to appropriately deal with predictable future conditions. This hypothesis has received support in the ecological and medical literature on diverse organisms. However, …

The Impact Of Student Loans On Homeownership, Matthew Eric Click
The Impact Of Student Loans On Homeownership, Matthew Eric Click
All ETDs from UAB
This thesis examines the relationship between student loan debt and homeownership. I hypothesize that a negative relationship exists, and control for a respondent’s age, household income, household size, race, gender, marital status, and level of education. Using a binary logistic regression model to examine data from the 2012 National Financial Capability Study (NFCS) and the 2014 Survey of Household Economic Decisions (SHED), I model the odds-ratios and predicted probabilities of homeownership for respondents with and without student loans. I find a decrease in the predicted probability of homeownership by 8.4% and 9.3% in the NFCS and SHED datasets, respectively. While …

On The Simplest Lamination Of A Given Identity Return Triangle, Brandon Lee Barry
All ETDs from UAB
Laminations are models for locally connected Julia sets of complex polynomials. This paper is concerned with laminations associated with degree 3 polynomials. We introduce and discuss simplest laminations and prove that subject to certain conditions a finite collection C of periodic polygons is associated with a simplest lamination L_C. This lamination is unique with respect to some collection of pullback schemes. We apply this result to the case where the collection C consists of the orbit of a periodic chord. We then introduce and characterize simple Fatou gaps by their boundary leaves and discuss the relationship between simple Fatou gaps …
