Oral Microbial Burden Of Periodontal Pathogens Among Orthodontic Patients, David Jolley

UNLV Theses, Dissertations, Professional Papers, and Capstones

Objectives

Many research studies involving orthodontic patients have a natural inclination to focus on changes in levels of cariogenic pathogens after bracket placement, and very few studies examine the role of changes of periodontal pathogens – particularly among adult patients. Interestingly, recent evidence suggests that increased levels of a specific periodontal pathogen, Fusobacterium nucleatum, may elevate risk for development of colon cancer in adults through direct pathways. Based upon this new evidence, the objective of the current study was to screen saliva samples taken from orthodontic patients to determine the prevalence of periodontal pathogens, including F. Nucleatum, T. denticola, and …

A Case Study: Students' Mathematics-Related Beliefs From Integrated Stem Model-Eliciting Activities, Cathrine Maiorca

UNLV Theses, Dissertations, Professional Papers, and Capstones

This case study examines the mathematics-related beliefs of fourth and fifth grade students who participated in an after-school integrated science, technology, engineering and mathematics (STEM) program where participants completed four Model-Eliciting Activities. The research questions addressed by this study are, What is the nature of the change in mathematics-related beliefs of students who participate in an after-school MEA program? In particular, what is the difference, if any, of the nature of the change in beliefs across varying ability levels? The framework used to describe these beliefs was developed by Kloosterman and includes beliefs about the nature of mathematics and mathematics …

Eight Steps To Weight Loss: Development Of An Evidence-Based Collaborative Provider-Patient Workbook For Overweight Or Obese Adults, Katherine Ann Wagner

UNLV Theses, Dissertations, Professional Papers, and Capstones

Despite decades of effort on the part of health care providers and policy makers to reduce the prevalence of obesity, the prevalence of obesity in the United States remains high (CDC, 2015). In the adult population ages 20 years of age and older, 35.7% are considered obese. The annual medical costs for people who are obese are $1,429 higher than people of a healthy weight (CDC, 2013). Obesity increases the risk for chronic health conditions such as hypertension, type 2 diabetes, hypercholesterolemia, coronary heart disease, stroke, asthma, arthritis, and cancer (Hammond & Levine, 2010). Over-weight and obesity are the main …
