Wnc Healthy Teens: A Multi-Level Teen Pregnancy Prevention Initiative, Katharine Macmillan

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

WNC Healthy Teens is a multi-component, community-based teen pregnancy prevention initiative. The program will be targeted in rural areas of Buncombe and Henderson Counties that have aggregate rates showing that over half the population of women aged 15-19 years are giving birth. Sexual education is necessary, but not sufficient to preventing risky sexual behaviors1. Tying multiple levels of evidence-based school interventions together with standardization of adolescent sexual health care will provide a well-rounded approach to address teenage pregnancy. Starting the initiative at age 14, it is anticipated the majority of teens will have yet to initiate sexual activity. Reducing the …

Colorectal Cancer Prevention In The North Slope Borough Of Alaska Utilizing The Flu-Fit Intervention, Jennifer Jenkins

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

The intention of the Flu-FIT intervention is to increase colorectal cancer screening rates by combing two annual activities into one visit that doesn’t necessitate a doctors visit. The original study increased colorectal cancer screening rates by 14 percentage points and this program should be able to show similar results in the North Slope Borough of Alaska. The North Slope Borough has the highest incidence rate of colorectal cancer in the United States, and this proposed intervention could lead to a reduction in that rate by increasing screening and knowledge about colorectal cancer in the community.

Investigating Cholera Using An Sir Model With Age-Class Structure And Optimal Control, K. Renee Fister, Holly Gaff, Elsa Schaefer, Glenna Buford, Bryce C. Norris

Biological Sciences Faculty Publications

The use of systems of differential equations in mathematical modeling in conjunction with epidemiology continues to be an area of focused research. This paper briefly acquaints readers with epidemiology, cholera, and the need for effective control strategies; discusses cholera dynamics through a variation on the SIR epidemiological model in which two separate age classes exist in a population; finds the numeric value for R₀ to be approximately 1.54 using estimated parameters for Bangladesh; and employs an optimal control resulting in a suggestion that a protection control be implemented at the end of the monsoon season.

Outcomes Assessment Within Prostate Cancer Interventions For Couples: A Narrative Review, Andrea M. Siguenza

Honors Undergraduate Theses

Current cancer research is beginning to address the psychosocial implications of a prostate cancer (PCa) diagnosis from not just the perspective of quality of life of the patient, but of his partner as well. Such inquiries have created novel intervention programs aiming to alleviate the adverse side effects that a PCa diagnosis may inflict on the couple.
Assessing efficacy of couple-based interventions, however, has been a difficult task due to the lack of homogeneity between studies regarding the operationalization process of primary outcome variables, as well as the instruments being used to measure them. This thesis, in response, aims to …

Comprehensive Sexuality Education In Kentucky, Luciana D. Hockersmith

Theses and Dissertations--Community & Leadership Development

Discussions of sex education of any kind can be controversial in a given setting. Traditional approaches to sex education prompt debate regarding effectiveness. Key indicators central to the effectiveness of sex education continue to be rates of teen pregnancy and transmission of sexually transmitted diseases (STDs). With discontentment surrounding the effectiveness of “traditional approaches,” a more wide-ranging method is worthy of being explored. The curriculum approach of Comprehensive Sexuality Education (CSE) includes six key concepts, and subsequent sub-concepts, intended to provide a broad and even all-inclusive range of topics for a similarly broad and even all-inclusive range of ages of …

Cellmapper: Rapid And Accurate Inference Of Gene Expression In Difficult-To-Isolate Cell Types, Bradlee D. Nelms, Levi Waldron, Luis A. Barrera, Andrew W. Weflen, Jeremy A. Goettel, Guoji Guo, Robert K. Montgomery, Marian R. Neutra, David T. Breault, Scott B. Snapper, Stuart H. Orkin, Martha L. Bulyk, Curtis Huttenhower, Wayne I. Lencer

Publications and Research

We present a sensitive approach to predict genes expressed selectively in specific cell types, by searching publicly available expression data for genes with a similar expression profile to known cell-specific markers. Our method, CellMapper, strongly outperforms previous computational algorithms to predict cell type-specific expression, especially for rare and difficult-to-isolate cell types. Furthermore, CellMapper makes accurate predictions for human brain cell types that have never been isolated, and can be rapidly applied to diverse cell types from many tissues. We demonstrate a clinically relevant application to prioritize candidate genes in disease susceptibility loci identified by GWAS.

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 …

An Exploration Of A State Mandated Health Education Program, Patricia Lyons

Walden Dissertations and Doctoral Studies

Shaken baby syndrome (SBS) is one of the most violent forms of physical child abuse. In 2007, the State of Ohio enacted a health education mandate known as Claire's law. Claire's law requires all birthing hospitals to provide SBS education to mothers prior to their discharge. This law is the result of public demand and advocacy initiatives; however, it was not clear how the mandate was developed or whether or not the mandate and subsequent educational programs have had an impact on efforts to prevent SBS. The purpose of this qualitative case study was to explore the state of Ohio's …
