With the rise of adolescent obesity, the need for treatment of this life-threatening disease is under consideration. There are several methods for the treatment of this disease, but a newer method is on the rise. Bariatric surgery for adolescents is a new technique that has been performed on adults for years, but the effects on the younger population are still unknown. There are certain criteria and guidelines for the patients undergoing this surgery, but the results seem to be promising. Nutritional and surgical complications are of great concern, but are the chronic disease health benefits brought on by weight loss …

The Evolution Of U.S. Foreign Policy Towards Cuba, Nicholas Drew Gordon

Undergraduate Honors Capstone Projects

Cuba's location has determined the island's political, social, and economic history. No other political entity in the Western Hemisphere has been as contested as Cuba has, and no other society has passed from colonial status, to a republic, to a socialist state in less than 100 years. The largest and most western island of the Antilles archipelago, Cuba is centrally located between North and South America, and guards access to the Caribbean Sea. For hundreds of years, its strategic position and its rich soil, abundant harbors, and mineral reserves have attracted foreign powers-first Spain, then the United States, and then …

The Benefits Of Optimism In A Student-Instructor Relationship, Johnathan Kyle Nelson

Undergraduate Honors Capstone Projects

The positive psychology movement of the past decade has produced an impressive amount of psychological literature devoted to studying the best of human attributes such as resilience, commitment, and optimism. This dramatic increase in available literature on optimism highlights a heightened awareness and interest in human proficiency, when so much of psychology has been traditionally devoted to the study of human deficiency. This research has lead to an increased understanding of what characteristics of an individual lead to facilitate various activities such as problem solving, leadership ability, income, achievement, sales, and job satisfaction. This study explored the relationship between positive …

Cardiovascular Medical Nutrition Therapy Looking At The Dash Trials, Rachel Anne Naegle

Undergraduate Honors Capstone Projects

OBJECTIVE: To review the recent medical literature on the effects of the DASH diet principles of increased fruits, vegetables, low-fat dairy, and decreased total and saturated fat; focusing on the intent to implement this dietary pattern to reduce hypertension, and thus to reduce cardiovascular disease.

FINDINGS: The combination diet reduced systolic by 5.5 mm Hg, and diastolic by 3.0 mm Hg as compared to the control diet (P<0.001 for each) (5, 7, 8). When comparing the two diet variables, the combination diet reduced systolic blood pressure 2.7 mm Hg, and diastolic 1.9 mm Hg more than the fruits-and-vegetables diet, (all with a P<0.001)! The results of the DASH-sodium (DASH II), proved also to substantially lower blood pressure when used with the combination diet.

CONCLUSION: Even though the DASH-sodium diet did decrease blood pressure, there is no scientific background to recommend this to all populations, and that instead of focusing attention on reducing sodium, efforts should …

The Adverse Health Effects Of Trans Fatty Acids, And Implications For Public Policy, Jonathan D. Atkin

Undergraduate Honors Capstone Projects

Subject: Trans fatty acids (TFAs) are produced either by the process of bacterial hydrogenation in the stomachs of ruminant animals, or the commercial method called industrial hydrogenation. The latter began early in the 20^th century based on purported health benefits and lowered costs. Alarming results from scientific studies in the early 1990's began to raise questions about whether TFAs should be regulated in our food supply.

Findings/Statistics: Scientific research initially discovered that TFAs raise the LDL/HDL ratio, thereby increasing the risk of coronary heart disease (CHD). Recent large, prospective, population-based studies have indicated a 25% increased risk of ischemic …

Cardiac Protein Rgs2: Structural And Functional Determinants, Stephanie Jan Chambers

Undergraduate Honors Capstone Projects

In this study, I explored the structure-function relationships of a cardiac RGS (regulator of G-protein signaling) protein, RGS2.

Contractions of the heart are triggered by calcium ions (Ca) entering heart cells through L-type Ca channels (1a). The activity of L-type channels (and thereby Ca influx) is modulated by cell surface receptors that couple to intracellular G proteins. G proteins in turn, are regulated by a newly-discovered family of proteins called RGS. RGS proteins speed the hydrolysis of GTP by G proteins, and thereby control the strength and duration of G protein-mediated signals. Stimulation of G proteins, which are coupled to …

The Macrobiotic Diet May Have Benefits In Cancer Prevention, Brittany Lewis

Undergraduate Honors Capstone Projects

Macrobiotics is one of the most popular alternative or complementary approaches to fighting cancer. The diet is primarily plant-based, is centered on the idea of an all encompassing "yin-yang" concept in life, mind, environment and food. The dietary components of the macrobiotic diet, along with the many lifestyle implications are shown to have beneficial effects in cancer prevention and therapy. The diet has many anti-carcinogenic compounds, as well as a decrease in foods thought to promote cancer. A cause for concern is the vitamin deficiencies that may ensue in following a strict macrobiotic diet, which typically results from an all …

Investigation Of The Toxic Affect Of Manganese On Ruminal Microbial Digestion And Growth, Erin Dearing

Undergraduate Honors Capstone Projects

This research investigated the toxic effect of manganese, in a reduced chemical state, on rumen microbial metabolism and growth. The reduced form of manganese is the soluble state found in subsurface waters and has a high red-ox potential. In the study, we investigated the effects of reduced manganese at varying concentrations, on rumen microbial ability to replicate and metabolize carbohydrates. The hypotheses that we tested were as follows: (1) reduced manganese decreases the rate of pH drop associated with rumen culture fermentation of a com based diet and (2) reduced manganese decreases the bacterial growth in rumen culture, as measured …

The Composition And Comparison Of Essential Oils And Their Nutritional Benefits To Enhance And Decrease Risk For Chronic Disease, Heather Wollschleger

Undergraduate Honors Capstone Projects

This paper reviews the current status of our knowledge of essential oils and their nutritional contribution to our diet. The effects of dietary fats on our health differ markedly from the type and form of the fat. Special emphasis is placed on omega-3 and omega-6 fatty acids, and their dietary involvement. Specific oils increase our levels of vital vitamin E and the essential omega-3 and omega-6 fats humans need for mental and physical health. Chronic diseases remain a major cause of death and disability, and risk factors include diets high in saturated fatty acids and trans fatty acids. This risk …

Alternative Futures For The Bear River Watershed, Richard E. Toth

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The Bear River Watershed (BRW) is located in northeastern Utah, southeastern Idaho, and southwestern Wyoming. Over the three states the watershed encompasses an area of 7,500 square miles (4,800,000 acres). The Bear River 's headwaters begin at close to 13,000 feet in the High Uintas Wilderness Area of northeastern Utah. The course of the river follows a horseshoe pattern flowing north through Wyoming, Utah, and Idaho before bending south at Soda Springs. The river then meanders through the Gem and Cache Valleys before reaching its delta at the Great Salt Lake at an elevation of 4,211 feet.

Occupational And Biopsychosocial Risk Factors For Carpal Tunnel Syndrome: A Case-Control Study, Jason Talley Goodson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The present study was designed to assess the risk factors associated with carpal tunnel syndrome (CTS). Toward this end, a wide range of putative occupational, biological, and psychosocial correlates of CTS was investigated using a case-control methodology. Cases were 87 patients from an orthopedic clinic with clinical symptoms and electrodiagnostic testing results suggestive of CTS. Controls were 74 gender-matched patients from the same orthopedic clinic, without clinical symptoms of CTS and normal electrodiagnostic testing results. Participants completed a self-report questionnaire that included eight potential occupational correlates (i.e., repetition, force, vibration, typing, lifting heavy loads, and standing on feet), 10 potential …

Weight Maintenance: Determinants Of Success, Cynthia Mitchell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This literature review was a selective examination of current obesity and physical activity research and opinions. Its purpose was more to evoke thought and discussion regarding the United States' obesity epidemic, rather than serve as an exhaustive account of prospective causes and solutions. Obesity and physical inactivity are major preventable health problems in the United States, but despite overwhelming evidence regarding the benefits of a healthy weight and regular physical activity, adult, childhood and adolescent obesity rates continue to escalate, creating significant health, medical and economic consequences.

While obesity rates soar, a small population percentage has proven successful in long-term …

Development And Evaluation Of An Electronic Food Frequency Questionnaire For Estimating Calcium Intake Among Multiethnic Youth, Siew Sun Wong

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Youth consuming inadequate amounts of calcium are at risk of developing osteoporosis later in life. To better assess dietary calcium intakes and the efficacy of dietary intervention strategies to improve bone health among youth, it is important to develop calcium intake assessment tools that are reliable, accurate, and interactively engaging for a new generation of youth who have a higher computer literacy and are more technologically knowledgeable than preceding generations. The goal of this dissertation was to develop and evaluate an electronic food frequency questionnaire (eFFQ) that measures calcium intake among 11-to 18-year-old Asian, Hispanic, and White youth. Enhancing this …

Catabolism Of Amino Acids To Volatile Fatty Acids By Lactococcus Lactis, Balasubramanian Ganesan

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Lactic acid bacteria are essential as flavor producers of cheese and fermented products. They are capable of catabolizing aromatic, branched chain, and sulfur amino acids to flavor compounds. During cheese ripening the numbers of lactococcal colonies decrease, but lactococci survive without replication in culture. This prompted an investigation into possible mechanisms of catabolism of branched chain amino acids into branched chain fatty acids and the physiological relevance of amino acid catabolism to the bacteria. We hypothesized that lactococci catabolize branched chain amino acids to branched chain fatty acids during nonculturability.

Lactococci, lactobacilli, and brevibacteria catabolized both branched chain amino acids …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

To determine the effects of a targeted curriculum and dual program involvement on childhood overweight status among low-income preschool children, a nutrition curriculum was developed. Three Special Supplemental Food Program for Women Infants and Children (WIC) clinics participated in the study: the control clinic, a clinic which received the targeted curriculum, and a third clinic which received the targeted curriculum and referred participant families to the Expanded Food and Nutrition lll Education Program (EFNEP). Participants were followed for six months. Data collected included anthropometrics, dietary intake, and parental behaviors.

Results showed a decrease in body-mass index percentile, slight improvements in …

Effect Of Non-Metabolized Sweeteners On Health Parameters In Humans, Matthew Alan Leonhardt

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The demand for functional foods is on the rise. These are food products that, besides providing energy and nutrients for life, provide additional health benefits. Xylitol, a five-carbon sugar alcohol, is a possible functional food, as well as a sugar replacement. The cost of xylitol has led manufacturers to add inulin, a nondigestible oligosaccharide, as an extender. Both xylitol and inulin have been suggested to provide added health benefits beyond being a reduced calorie replacement for sugar. We tested their impact on several human health parameters (fecal weight, fecal pH, fecal % moisture, blood lipids, blood glucose, and fecal micro …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Studies have reported mixed results for people with or without diabetes with cognitive decline or Alzheimer's disease (AD). Cognitive decline and AD among people with diabetes will be the focus of much discussion since results have been controversial.

The study examined whether diabetes is associated with cognitive decline and whether it is an independent risk factor for the development of AD among elderly residents of Cache County, Utah.

Results revealed an association between diabetes and a lower average Modified Mini Mental State Examination (3MS) score of nearly a point lower at baseline. Results also showed an association between diabetes and …

Identification Of Factors Affecting Susceptibility To Depression And Influencing Quality Of Life In Adult Cystic Fibrosis Patients Based On Age-At-Diagnosis, Marlene Israelsen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Approximately 10% of cystic fibrosis (CF) cases remain undiagnosed until age 18 or later and medical professionals are still unclear about the needs of these individuals. Adults with CF must either adapt to life with a chronic disease or transition into adulthood with CF. The purpose of this study was to address the impact of age-at-diagnosis on quality of life in a CF adult population.

The psychological functioning of 21 adult CF patients (seven adult-diagnosed (AD) and 14 pediatric-diagnosed (PD)) was assessed using the Beck Depression Index (BDI)-II. A descriptive review of demographic and clinical data, which included an assessment …

Nutrition Education For Parents Of Children With Cystic Fibrosis : Assessment Of Needs And Strategies For Improved Knowledge And Confidence In Self Care, Catherine M. Mcdonald

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Suboptimal growth and nutritional status are problematic for children with cystic fibrosis (CF). Optimal nutrition predicts better lung function and longevity. Daily nutrition therapy for children with CF requires adequate food resources, knowledge of appropriate nutrition and behavior management skills, and confidence in one's ability to correctly apply the necessary skills. The Mountain West Cystic Fibrosis Consortium Questionnaire (MWCFC-Q) was designed as an educational needs assessment for parents of children with CF. The goal was to identify areas of concern that could be targeted for educational intervention to ultimately improve children's growth and nutritional status.

Data analyzed from 305 returned …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study examined the relationship of three types of martial commitment and religiosity factors in a random sample of I ,316 Utah adults. Participants were surveyed to assess attitudes of marriage, divorce, and marriage education. A lack of commitment was cited by 83% of divorced adults as a major factor for their divorce. The level of commitment to spouse, commitment to marriage, and constraint commitment was determined by extrapolating items from the 2003 Utah Marriage Movement Statewide Baseline Survey. Religiosity included measures of the frequency of church attendance, church affiliation, and religious values. Regression analyses that included socio-demographics showed the …

Identifying Temporal Trends In Treated Sagebrush Communities Using Remotely Sensed Imagery, Eric D. Sant

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The sagebrush shrub steppe ecosystem is of great concern to researchers, conservationists, and the general public because of the documented declines associated with it. Monitoring in the past has generally been point-based and lacking in long-term data. To overcome these deficiencies, an automated method of monitoring was developed using GIS and remote sensing.

Geospatial layers of vegetation, soils, fire history, roads, streams, and springs were acquired and processed to characterize selected monitoring locations. A temporal set of Landsat satellite imagery for the past 30 years was normalized to reduce the effects of sun angle, haze, and sensor change. After normalization, …

Wildlife-Vehicle Collisions In Utah: An Analysis Of Wildlife Road Mortality Hotspots, Economic Impacts And Implications For Mitigation And Management, Christine A. Kassar

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In the US, the roaded landscape has had serious ecological effects. We studied wildlife-vehicle collisions occurring on the 248 state routes in Utah from 1992 to 2002. We tracked trends and patterns in deer-vehicle collisions, evaluated all routes for frequency of deer kills, and identified "hotspots" (segments of road with high concentrations of collisions per mile). We found pronounced patterns: e.g., 61.15% of all collisions occurred on only 10 routes. We studied the effects of posted speed limit and annual average daily traffic flow and found that no relationship existed between traffic volume and/or posted speed limit and the number …
