Assessment Of Her2-Neu In Breast Cancer Lines Upon Differential Exposures To Xenoestrogens, Abha Aggarwal
Assessment Of Her2-Neu In Breast Cancer Lines Upon Differential Exposures To Xenoestrogens, Abha Aggarwal
Walden Dissertations and Doctoral Studies
Synthetic xenoestrogens have differential estrogenic properties. Research has shown that exposures to xenoestrogens could promote breast cancer by disrupting normal function of the human epidermal growth factor receptor 2 (Her2) gene. Although animal models demonstrated a connection between xenoestrogen exposure and Her2 activity, no study using human cells has systematically examined their carcinogenic potential influencing the Her2 gene expression. Furthermore, breast cancer cells are phenotypically disparate (ER+, Her2+), with some phenotypes (Her2+), leading to more aggressive disease. This study aimed to dosimetrically assess the carcinogenic potential of commonly used xenoestrogens influencing Her2 gene expression, and delineate cellular phenotypes at greater …

Methylmercury Exposure Via Canned Tuna Fish Consumption And Breast Cancer, Jennifer Bodenrader
Methylmercury Exposure Via Canned Tuna Fish Consumption And Breast Cancer, Jennifer Bodenrader
Walden Dissertations and Doctoral Studies
Widespread consumption of canned tuna fish since the 1950s may explain some of the increase in breast cancer prevalence in the United States and Europe. Although canned tuna is the primary source of human exposure to methylmercury, its role as an estrogen activating metalloestrogen has been overlooked in the etiology and incidence of breast cancer. Carcinogenic theory asserts that increased exposure to estrogen elevates the risk of breast cancer. The purpose of this population-based, case control study was to examine the association between canned tuna consumption, total blood mercury, and breast cancer in the NHANES 2003-2006 surveys. A multivariable logistic …

Walden Dissertations and Doctoral Studies
Dengue fever is a debilitating, viral, mosquito-borne disease occurring in tropical and subtropical areas in the world. The majority of dengue cases in the United States were acquired in endemic areas by travelers or immigrants. However, in recent years, autochthonous (locally acquired) dengue cases have been diagnosed in Florida. The purpose of this study was to find an association between potential risk factors and the expansion of dengue fever in the United States. Guided by the eco-bio-social framework, which offers a broad assessment of risk factors for the illness, a retrospective design was used with archival data to correlate changes …
The Distribution Of Type 1 Diabetes Onset In The United States By Demographic Factors, Margaret Beckstrand
The Distribution Of Type 1 Diabetes Onset In The United States By Demographic Factors, Margaret Beckstrand
Walden Dissertations and Doctoral Studies
Type 1 diabetes (T1D) is a chronic and lifelong condition, often diagnosed in childhood. Patients with T1D are at elevated risks of associated health complications, comorbidities, and mortality. Occurrence, clinical presentation, and complications related to T1D differ by age of onset, ethnicity, and gender. The last reported population-based estimates regarding the burden of T1D in children using the National Health and Nutrition Examination Survey (NHANES) were published in 2008, and these estimates were not well stratified by age of onset, ethnicity, and gender. The purpose of this study was to examine these demographics within the conceptual framework of the hygiene …

Refining Computerized Physician Order Entry Initiatives In An Adult Intensive Care Unit, Chevita Fuller
Refining Computerized Physician Order Entry Initiatives In An Adult Intensive Care Unit, Chevita Fuller
Walden Dissertations and Doctoral Studies
Computerized physician order entry (CPOE) is used in healthcare organizations to improve workflow processes and transcription, as well as to prevent prescribing errors. Previous research has indicated challenges associated with CPOE for end-users that predispose patients to unsafe practices. Unsafe CPOE practices can be detrimental within the intensive care unit (ICU) setting due to the complexity of nursing care. Consequently, end-user satisfaction and understanding of CPOE and electronic health record (EHR) functionality are vital to avoid error omissions. CPOE initiatives should be refined post system implementation to improve clinical workflow, medication processes, and end-user satisfaction. The purpose of this quality …

The Use Of Human Patient Simulators To Enhance The Clinical Decision Making Of Nursing Students, Sharon Kay Powell-Laney
Walden Dissertations and Doctoral Studies
One of the newest teaching modalities in nursing education is the use of human patient simulators (HPS). An HPS simulation scenario creates a software program vignette in which students interact with a manikin to practice caring for critical patients in a risk-free environment. Although used extensively in schools of nursing, there is little research that examines if these expensive simulators improve the clinical decision-making ability of nursing students. The purpose of this experimental differentiated treatment study was to assess if HPS technology leads to increased clinical decision-making ability and clinical performance more than the teaching modality of a paper and …
