Dissertation: Sociodemographics And Pancreatic Cancer Survival Rate, Sylvester Lewis

Walden Dissertations and Doctoral Studies

Pancreatic carcinoma or pancreatic cancer (PaCa) is an insidious disease with a prognosis of 6- to 12-month survival time for a late stage diagnosis. This problem has become crucial given that no study to date had been able to establish a definitive association between independent factors (other than a few diseases) and the survival rate of pancreatic cancer. The purpose of this quantitative, cross-sectional study was to determine whether an association exists between the independent, sociodemographic variables (marital status, age, education, income, and employment) and the outcome variable of survival rate. The social cognitive theory was the framework that provided …

Impact Of Social Support On Malaria Management By Burundian Community Health Workers, Bonaventure Bazirutwabo

Walden Dissertations and Doctoral Studies

Malaria is the main cause of mortality for children under the age of 5 in Burundi. The access to malaria diagnostics and treatment is hampered not only because of logistical issues, but also due to the lack of qualified human resources and their inequitable distribution across the country. To mitigate the lack of human resources for health, the government of Burundi, along with its partners, shifted some tasks to community health workers (CHWs) to cover unmet healthcare needs for selected diseases such as malaria, diarrhea, and pneumonia. The purpose of this study was to determine whether the social support provided …

Bleach-It-Away Clostridium Difficile, Kim Ione Hecker

Walden Dissertations and Doctoral Studies

Hospital-associated infections (HAIs) are infections patients contract as a result of being hospitalized. HAI rates decreased for almost all pathogens in the past few years, with the exception of Clostridium difficile infections (CDIs), which have been steadily climbing, placing hospital-acquired CDI at the top of the HAI list. The Center for Disease Control and Prevention reported in 2010 almost a half a million people were infected with CDIs yearly in the United States, and CDIs claimed the lives of approximately 29,000 people, representing a 4-fold increase from 1993. To address the problem in the local hospital, a quality improvement initiative …

Association Of Objective Measures Of Sleep And Inflammation Markers On Police Officers: A Cross-Sectional Analysis, Megan R. Buss

Theses and Dissertations

Police officers are a unique occupational group due to the fact that they have more health problems than many other occupations. These health problems could be a result of elevated inflammation markers caused by poor sleep. Sleep influences circadian rhythms, which thereby influences the function of the immune system. The immune system is responsible for the body’s inflammatory response using pro-inflammatory cytokines such as IL-6, CRP, Fibrinogen, and TNF-a. These cytokines can become elevated if disruption of the sleep cycle occurs. Elevated levels of inflammatory markers are associated with increased risk of cardiovascular disease. Police officers also work shifts and …

1) To assess the economic burden …

The Impact Of Mother–Father Relationship, Social Support And Neighborhood Context On Preterm Birth, Timothy O. Ihongbe

Theses and Dissertations

Background: Preterm birth is a major public health concern in the US. Previous studies have suggested that quality of the mother-father relationship, social support, and neighborhood violence may be associated with preterm birth; however, findings are equivocal.

Objectives: The main objectives of this dissertation were: 1) to determine the modifying effect of perceived residential environment on the association between quality of mother–father relationship and preterm birth in a sample of African-American women, 2) to examine whether the receipt of social support modifies the association between neighborhood violence exposure and preterm birth in a nationally representative sample of US women, and …

Spatial Modelling And Wildlife Health Surveillance: A Case Study Of White Nose Syndrome In Ontario, Lauren Yee

Theses and Dissertations (Comprehensive)

Wildlife data is often limited by survey effort, small sample sizes, and spatial biases associated with collection and missing data. These factors can create unique challenges from a surveillance perspective when trying to extract spatial patterns of habitat suitability and disease distributions for conservation and management purposes. This thesis examined data quality from a wildlife health database in the context of spatial analysis of wildlife disease. Spatial analysis of the data to predict habitat suitability of bats and white nose syndrome afflicted bats was examined by using the MaxEnt modelling method. Methods to reduce spatial bias were examined and specific …

Rare Single Gene Disorders: Estimating Baseline Prevalence And Outcomes Worldwide, Hannah Blencowe, Sowmiya Moorthie, Mary Petrou, Hanan Hamamy, Alan Bittles, Stephen Gibbons, Matthew Darlison, Bernadette Modell, Congenital Disorders Expert Group .

Research outputs 2014 to 2021

As child mortality rates overall are decreasing, non-communicable conditions, such as genetic disorders, constitute an increasing proportion of child mortality, morbidity and disability. To date, policy and public health programmes have focused on common genetic disorders. Rare single gene disorders are an important source of morbidity and premature mortality for affected families. When considered collectively, they account for an important public health burden, which is frequently under-recognised. To document the collective frequency and health burden of rare single gene disorders, it is necessary to aggregate them into large manageable groupings and take account of their family implications, effective interventions and …

ETSU Faculty Works

Diabetes is a highly prevalent chronic disease among US adults, and its prevalence among US veterans is even higher. This study aimed to examine the prevalence of and trends in diabetes in US veterans by using data from the US National Health and Nutrition Examination Survey from 2005 through 2014. The overall prevalence of diabetes and undiagnosed diabetes was 20.5% and 3.4%, respectively, and increased from 15.5% in 2005–2006 to 20.5% in 2013–2014 (P = .04). Effective prevention and intervention approaches are needed to lower diabetes prevalence among US veterans and ultimately improve their health status.

Antibiotic Resistance In Escherichia Coli Iron Transport Mutants, Madeline Brandt

Honors Projects

Studies previously completed on Escherichia coli mutants suggested the possibility of iron uptake as an influence on the antibiotic resistance seen in different strains. The research focused on the TonB energy transduction system and its contributions to efflux-mediated antibiotic resistance. To test the hypothesis that iron uptake has an influence on antibiotic resistance in Escherichia coli, the sensitivity to a variety of antibiotics was evaluated in strains of E. coli lacking genes that relate to the uptake of iron or the efflux system that is necessary for the uptake of iron. To test the efflux systems TolC and TonB …

Effect Of Total Body Iron On Metabolic Dysfunction Among U.S. Females In The Nhanes 2003-2010, Aged 12-49., Joseph Michael Carhart

Electronic Theses and Dissertations

Experimental and epidemiological studies have reported positive associations between iron parameters and metabolic dysfunction including: Type 2 diabetes mellitus (T2DM) (1-6), metabolic syndrome (7-15), non-alcoholic fatty liver disease (NAFLD) (16-22) and insulin resistance (23,24) with a number of studies showing that reductions in total body iron via dietary modification (e.g., reducing red meat intake) or phlebotomy lead to increases in insulin sensitivity (25), decreases in insulin resistance (26), and reductions in the prevalence of complications associated with T2DM (5, 27), metabolic syndrome (28) and NAFLD (22, 29). Moreover, the risk associated with these outcomes and total body iron differ between …

Moving Mountains : A Study Examining Long-Term Impacts Of Mountaintop Removal Coal Mining On Mortality In The Appalachian Region Using Geographic Information Sciences Techniques., James Howard Kent Pugh

Electronic Theses and Dissertations

Over the last hundred years, the Appalachian region has been dominated by the coal industry. It has also been and currently is one of the unhealthiest regions in the United States. Recent scholarship has examined the relationship between coal mining and health and mortality rates in the Appalachian region. The first study incorporates air quality and pollution data to examine if coal mining counties have higher levels of pollution and if this pollution contributes to mortality disadvantage. In the second study, I construct a population-based coal-exposure measure to better evaluate the relationship between coal mining and health I find that …

Quality Of Life: Socio-Demographic And Genetic Determinants As Well As Links With Cancer Outcomes, Jeanne Pierzynski

Dissertations and Theses (Open Access)

Quality of life (QOL) is an independent prognostic factor for cancer. Lung cancer is the leading cause of cancer death. Breast cancer is the most diagnosed. Bladder cancer is the most expensive cancer to treat because of its high recurrence rate. We set to perform comprehensive analyses of predictors of QOL in these cancer sites with the future goal of improving QOL and outcomes.

In 6,456 newly diagnosed lung cancer patients, we investigated the relationship between baseline patient characteristics and QOL to identify determinants of QOL. A QOL questionnaire (SF-12v1) measured patients’ physical component summary (PCS) and mental component summary …
