Knowledge, Beliefs, And Perceptions About Tuberculosis Among Haitian Immigrants And Haitian Americans Living In Miami-Dade County, Florida, Leslie Barbour

Walden Dissertations and Doctoral Studies

Tuberculosis (TB) kills 1.7 million people each year, and 1/3rd of the world's population is estimated to have latent TB. It was once the deadliest disease in the United States but is now relatively rare and, if treated properly, it is curable. Migrants from TB-endemic countries, such as Haiti, are one source of TB transmission to the US, and the prevalence of TB remains high and is increasing in Little Haiti, Florida. Data on the knowledge and perceptions of Haitian immigrants and Haitian Americans about TB is inadequate. The purpose of this qualitative research was to study the TB-related knowledge, …

Challenges Of Aging With The Hiv Virus And Comorbidities, Rommie Navylia Abele

Walden Dissertations and Doctoral Studies

Since the introduction of antiretroviral therapy, the survival rate of infected HIV patients has been on the rise with a predicted increase by 2030. The longer a person lives with the virus, the more prone to HIV-associated chronic diseases he or she becomes, but it is not clear whether these diseases are solely from aging with the virus or from long-term use of antiretroviral therapy. Scientists demonstrated that the introduction of antiretroviral therapy led to an increased life expectancy yet early onset of comorbidities; however, they failed to address the challenges that people 50 years old or older face, as …

Racial/Ethnic Differences In The Treatment Of Elderly Non-Small Cell Lung Cancer Patients, Cheryl Mokrzecky

Furthermore, multiple causes of death (MCOD) data offer important information that could not possibly be gathered from other mortality data. This study aimed to describe the interrelationships between various causes of death in the United States in order to improve the understanding of the coexistence of MCOD and thereby improve public health and enhance longevity. The social support theory was used as a framework, and multivariate linear regression analyses were conducted to …

Association Between Androgen Deprivation Therapy For Prostate Cancer And Alzheimer's Disease, Gina Giannantoni-Ibelli

Walden Dissertations and Doctoral Studies

Alzheimer's disease (AD) is the most common progressive, neurodegenerative disease and form of dementia. The hallmarks of AD are extracellular accumulation of amyloid beta protein, resulting in neuritic, senile plaques and intracellular accumulation of tau protein. AD mainly arises from imbalance of amyloid beta protein production and its clearance in the brain. Testosterone modulates production of amyloid beta protein by decreasing its accumulation. Prostate cancer remains a substantial public health challenge in the United States. While androgen deprivation therapy (ADT) is an effective treatment for prostate cancer, it may be associated with cognitive impairment due to decreased levels of testosterone. …

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 Between Genetic Ancestry And Body Mass Index Among A Cohort Of Hispanic American Children, Sahel Hazrati

Walden Dissertations and Doctoral Studies

Childhood obesity is disproportionately higher among children from Hispanic backgrounds. Ethnicity is a social and cultural construct and does not capture true ancestral heterogeneity. Hispanic Americans have a wide variety of genetic admixture proportions of European (EUR), Native American (AMR), and African (AFR) ancestry. The objective of this cross-sectional study was to assess the contribution of ancestral genetic composition to body mass index (BMI), and to evaluate the relationship of obesity risk factors to BMI among 154 2-year-old Hispanic American children. The theory of Evolutionary Developmental Biology was utilized to investigate the relationship between children's growth process and ancestral background. …

Latent Tuberculosis Infection Treatment Completion And Predictors Of Noncompletion Among Visa Holders In The Rural Setting, Scott Hutton

Walden Dissertations and Doctoral Studies

Latent tuberculosis infection (LTBI), a product of exposure to Mycobacterium tuberculosis (Mtb), can lead to tuberculosis (TB) and further cause death if untreated. Fortunately, TB can be prevented with LTBI treatment. Targeting newly arrived visa holders for LTBI screening and treatment is an effective strategy for decreasing future TB burden. However, LTBI treatment completion rates are low, and researches had primarily focused on the nonrural U.S. setting. This study, using a retrospective cohort design under the epidemiological disease triangle framework evaluated (a) the treatment completion rates for 2 cohorts of visa holders (i.e., immigrants, N = 31 and refugees, N …
