A Correlational Pilot Study Of Fatalism And Self-Efficacy Among Appalachians With Type Ii Diabetes Mellitus., Dwyn Mounger

Undergraduate Honors Theses

Despite the vast amount of research regarding type II diabetes, little is known about the relationship between fatalistic beliefs and self-efficacy in individual self-care among adult Appalachians with type II diabetes. As a result of multiple predisposing risk factors that include high rates of obesity and poverty, as well as a lack of access to preventative care services, the prevalence of diabetes is very high in this region and has become a major health issue. In addition, a history of exploitation and lack of diverse economic development has profoundly influenced the cultural beliefs of those living within the region, which …

Does Pregnancy Intent Impact The Decision To Breastfeed?, Rachel Collins

Undergraduate Honors Theses

Current literature overwhelmingly supports the benefits of breastfeeding for mothers and infants. Numerous studies significantly correlate specific demographics and background factors of breastfeeding and non-breastfeeding mothers. However, little research has focused on the intendedness of the pregnancy and its association with breastfeeding. The goal of this study was to examine the association between pregnancy intendedness and breastfeeding plans and behavior. The first question of interest examined was whether pregnancy intent was associated with a woman’s intent to exclusively breastfeed when asked during the third trimester, after control for potentially confounding differences between the two groups. The second question of interest …

Evaluation Of Heat Stress In Migrant Farmworkers, Stephen L. Mcqueen

Electronic Theses and Dissertations

The rate of heat-related fatalities in crop production workers is almost 20 times that of other industries. Heat stress was investigated in migrant tomato workers in July, 2012, using measurements of body temperature, heart rates, body weight loss, evaluation of the thermal environment, and survey data. Using occupational safety criteria, these workers were found to work in an environment that should require protective measures to prevent heat strain. Increases in body temperature, heart rate, and physiological strain correlated with heat exposure. One third of workers had body weight percentage losses that indicated dehydration. However, working in hot environments appears to …

Expectations And Experiences Of Fathers Who Have Parented Children With And Without Intellectual Disabilities, Jane Christina Kusmik Walker

Electronic Theses and Dissertations

The parenting experience is as diverse as the children parented. Each child has diverse personality traits requiring flexibility and specificity in parenting strategy. This need for flexibility and specificity is more complex when one or more children within a family has an intellectual disability. Although research in this area is abundant, investigators have historically focused on mothers' attitudes, beliefs, and behaviors to represent the entire family (Essex, Seltzer, & Krauss, 2001; Greenberg, 2002) rather than focusing on fathers and their caregiving relationships with their children in need of malleable but consistent parenting. Using a qualitative descriptive design, this qualitative study …

Rapid Detection Of Streptococcus Mutans In Saliva, Catherine E. Holtman

Electronic Theses and Dissertations

Documentation exists that mothers can pass the cariogenic bacteria Streptococcus mutans to their infants. The newest technology to identify Streptococcus mutans is a rapid detection saliva test. Two hundred patients above the age of 18 were targeted using random selection in a Louisville, Kentucky dental office. Patients signed an informed consent form and were given a qualifying questionnaire. Patients received 2 bitewing x-rays and a charted DMFT index and were administered the saliva test. While the null hypothesis was rejected using the chi square test, the results were inconclusive due to expected values. However, other chi square results revealed that …

Il-1Β Amplification Of Nitric Oxide Production And Its Inhibitory Effects On Glucose Induced Early Growth Response-1 Expression In Ins-1 Cells, Ada Young

Electronic Theses and Dissertations

The pathophysiology of cytokines released by infiltrating white blood cells upon pancreatic beta cells is not fully understood. Early growth response gene-1 (Egr-1) expression is specifically and transiently up regulated in pancreatic beta cells in response to glucose. We hypothesized that interleukin-1 beta (IL-1▀) induction of nitric oxide alters glucose induced Egr-1 transcription levels. Egr-1 levels were assessed via western blot, nitric oxide was measured with a Griess Reagent kit and insulin levels via ELISA. Glucose induced both insulin and Egr-1 production in INS-1 cells. IL-1▀ dose dependently increased nitric oxide production over time and significantly attenuated glucose induced Egr-1 …

Advancing Global Tobacco Control: Exploring Worldwide Youth Attitudes And Behaviors Toward Tobacco Use And Control, Sreenivas Phanikumar Veeranki

Electronic Theses and Dissertations

Tobacco use continues to be the leading cause of preventable death in the world. The disproportionate increase in tobacco use in low- and middle-income countries needs immediate attention. Many smokers begin smoking as adolescents and are most likely to become permanent smokers. Moreover, youth are highly targeted by tobacco industry strategies. However, a gap exists in literature to understand worldwide youth tobacco use and control. The purpose of this study is to 1) identify factors that influence never-smoking youths‟ smoking susceptibility, 2) explore characteristics that influence youth exposure to environmental tobacco smoke (ETS) and 3) to delineate key determinants of …

Effects Of Burn Injury On Biological Ethanol And Ethyl Glucuronide Concentrations, Trista Haupt Wright

Electronic Theses and Dissertations

Alcohol is the most abused drug in the United States and most frequently performed assay in forensic laboratories. Alcohol is routinely present in biological specimens from fatal residential fires and forensic toxicologists must interpret if these individuals are impaired by determination of their blood alcohol concentrations on post-incineration blood collected at autopsy. There is no known data available to confirm or refute blood alcohol concentrations and impairment in fire-related deaths. Ethyl glucuronide (EtG), a non-volatile minor ethanol metabolite, may provide a better biomarker for ethanol consumption prior to burn injury. The literature does not address the possibility that ethanol or …

Predictors Of Success To Pass The National Physical Therapy Exam: Is There A Correlation Between Gre/Gpa Scores And Success Rates?, Kelsey Taylor

Undergraduate Honors Theses

The Graduate Record Exam (GRE) is an admission criterion for many different graduate programs including the Doctorate of Physical Therapy (DPT). Upon completion of a DPT program, the National Physical Therapy Exam (NPTE) must be passed with a minimum score of 600 in order to practice as a physical therapist. This study analyzes the relationship between GRE and graduate grade point average (GGPA) and NPTE scores to explore the ability of GRE and GGPA scores to predict NPTE success. Similar studies have been done in the past, but the results vary between studies. GRE, GGPA, and NPTE records were gathered …

Random Inter Stimulus Interval Increases Signal-To-Noise Ratio., Juliane Armstrong

Undergraduate Honors Theses

Incremental improvements are continuously being made to P300-Speller BCI paradigms. Accurate classification depends on a high signal-to-noise ratio (SNR) between the target and nontarget items. Fixed presentation rates produce a large flash-evoked response that persists throughout the recording epoch, which can potentially undermine the classification of P300-responses. By introducing a random interstimulus interval (ISI) to a previously improved P300-Speller paradigm (i.e., Checkerboard Paradigm; CBP) we expect to reduce the deleterious flash-evoked responses and increase the P300 classification SNR. Data were recorded from 32 EEG locations (right mastoid referenced) from 13 subjects using the CBP with two conditions. In the Random …

The Effects Of Nicotine Administration On Behavior And Markers Of Brain Plasticity In A Rodent Model Of Psychosis, Marla K. Perna

Electronic Theses and Dissertations

Schizophrenia affects about 1% of the population. A hallmark of the disorder is increased dopamine D2 receptor sensitivity in the brain. Studies have shown that schizophrenics smoke cigarettes at approximately 4 times the rate of the general population. It has been suggested that nicotine use is a form of self-medication for symptoms in schizophrenia. Smoking behaviors typically begin in adolescence. We assessed effects of nicotine on behavior and brain plasticity in an adolescent rodent model of schizophrenia with the goal of identifying targets for smoking cessation. Methods: Rats were neonatally treated with quinpirole (a D2/D3 agonist) or saline and sensitized …

A Consensus Model For Electroencephalogram Data Via The S-Transform, Andrew Coady Young

Electronic Theses and Dissertations

A consensus model combines statistical methods with signal processing to create a better picture of the family of related signals. In this thesis, we will consider 32 signals produced by a single electroencephalogram (EEG) recording session. The consensus model will be produced by using the S-Transform of the individual signals and then normalized to unit energy. A bootstrapping process is used to produce a consensus spectrum. This leads to the consensus model via the inverse S-Transform of the consensus spectrum. The method will be applied to both a control and experimental EEG to show how the results can be used …

Clinical Simulation Laboratories: Bridging The Gap Between Academia And The Private Care Hospital Setting., Caitlin Carney

Undergraduate Honors Theses

Many academic medical programs present students with the chance to experience scenario based learning. This is often achieved through the use of clinical simulation laboratories which utilize computer-based scenarios that realistically imitate the human body and how it responds to various situations. This interactive style of learning has proven to be successful at integrating theories taught in textbooks and practice gained through clinical experience without posing any harm to human patients. Literature has shown documentation of the effectiveness of using clinical simulation laboratories in both the academic and clinical setting; however, some clinical facilities have been slow to adapt the …

Exploring The Unique Characteristics Of Cancer In Adolescents And Young Adults In Tennessee, Megan Quinn

Electronic Theses and Dissertations

Adolescents and Young Adults (AYAs) ages 15-39 years with cancer have received little attention in the medical and health fields, resulting in a lack of progress for this age group. Little is known about the unique biologic, epidemiologic, and psychosocial issues that play an integral role in the AYA cancer journey. The purposes of this study were to use the Tennessee Cancer Registry for all new cancer cases from 2004-2008 to determine 1) the main types of cancer that affect AYAs in TN, 2) the predictors of late-stage diagnosis of melanoma, and 3) the factors that predict a total thyroidectomy …

A Measurement Of Readiness For Tennessee Hospitals To Implement “Meaningful Use” Criteria Resulting From The American Recovery And Reinvestment Act, 2009, Kathryn Wallin Wilhoit

Electronic Theses and Dissertations

In 2009, the American Recovery and Reinvestment Act was signed into law. This legislation provided for monetary rewards for those acute-care hospitals that meet "meaningful use" computerization and reporting criteria.

The study used a descriptive, nonexperimental design to answer three research questions (1) What is the level of readiness to meet "meaningful use" criteria in the Tennessee Hospital Association (THA) member hospitals; (2) What is the level of readiness to meet "meaningful use" criteria in the rural THA member hospitals; and (3) Is there a difference in the readiness to meet "meaningful use" criteria between rural and urban THA member …

Prelamin A Influences A Program Of Gene Expression In Regulation Of Cell Cycle Control, Christina N. Bridges

Electronic Theses and Dissertations

The A-type lamins are intermediate filament proteins that constitute a major part of the eukaryotic nuclear lamina—a tough, polymerized, mesh lining of the inner nuclear membrane, providing shape and structural integrity to the nucleus. Lamin A (LA) filaments also permeate the nucleoplasm, providing additional structural support, but also scaffolding numerous tethered molecules to stabilize, organize, and facilitate molecular interactions to accomplish critical functions of cellular metabolism. Over the past 2 decades, much attention has been focused on roles of LA in maintenance of nuclear structural integrity. Only since the late 1990s have scientists discovered the devastating effects of LA gene …

Stabilization Of The Cardiac Nervous System During Cardiac Stress Induces Cardioprotection, David D. Gibbons

Electronic Theses and Dissertations

The cardiac nervous system consists of nested reflex feedback loops that interact to regulate regional heart function. Cardiac disease affects multiple components of the cardiac nervous system and the myocytes themselves. This study aims to determine: 1) how select components of the cardiac nervous system respond to acute cardiac stress, including myocardial ischemia (MI) and induced neural imbalance leading to cardiac electrical instability, and 2) how neuromodulation can affect neural-myocyte interactions to induce cardioprotection. Thoracic spinal cord stimulation (SCS) is recognized for its anti-anginal effects and ability to reduce apoptosis in response to acute MI, primarily via modulation of adrenergic …
