A Prototype Miniaturized Metabolic Gas Analysis Sensor, Tammy Anderson, Joseph Orr

Utah Space Grant Consortium

Microgravity adversely affects several physiological systems. As space exploration moves to extended flights, understanding which mechanisms microgravity influences may contribute to the health and safety of astronauts aboard. Maximum oxygen consumption (VO₂ max) testing is used to monitor changes to cardiorespiratory function. Currently the equipment used to such testing aboard the International Space Station (ISS) is large and requires a significant amount of power. We propose the use of a modified metabolic management system, currently approved for clinical use, for exercise stress testing.

Evaluating The Effects Of Hypercapnia On Recovery Time And Nausea In The Post Anesthesia Care Unit, Cameron Jacobson, Derek Sakata

Utah Space Grant Consortium

Hypercapnia is often used to accelerate emergence from general anesthesia in the operating room, but little is known about the postoperative effects that may carry over to recovery in the post anesthesia care unit. We have designed two studies to address this topic, one of which has been completed. The first study monitored 22 patients undergoing eye surgery who received general anesthesia using desflurane. During emergence, half of the patients were hypercapnic and ventilated at twice their minute volume. After the desflurane was turned off the hypercapnic group open their eyes on command 4.1 +/- 1.4 min later, while the …

Vitamin D Deficiency In The United States: How Common Is It?, Christine N. Arnold

Undergraduate Honors Capstone Projects

Background: Vitamin D deficiency in the US is more prevalent than before estimated. Given the numerous roles vitamin D plays in the body, it is becoming apparent that the need for adequate intake is vital. It is generally accepted that adults require 1,000 IU per day.

Methods: Electronic searches were conducted using Google Scholar and Elsevier databases. Search terms included “vitamin D deficiency”, “vitamin D deficiency US”, and “vitamin D screening”. Databases were reviewed for prevalence of vitamin D deficiency in the US.

Results: Populations at high risk for deficiency include the elderly, adolescents, people with darker skin, those who …

Weight Discrimination: Why Current Perceptions Need To Change, Kelsey Rae Eller

Undergraduate Honors Capstone Projects

Discrimination based on weight has been labeled the last form of socially acceptable prejudice. Weight discrimination is becoming more and more prevalent in schools, the workplace, social settings, the media, and even in healthcare. Overweight and obese individuals are often stereotyped as lazy, addicted to food, and lacking self-discipline and initiative, and as a result may struggle with decreased employment opportunities, fear and shame in public, attempting dangerous weight loss methods, or even eating disorders.

This project seeks to identify and examine research that has been done on this subject in order to increase awareness of weight bias and to …

An Investigation Of Dietary Supplementation As A Potential Source Of Nutrition Misinformation Hindering The Development Of Healthy Eating Habits In The College Population, Mary Dimmick

Undergraduate Honors Capstone Projects

Current dietary supplement legislation allows nutrition misinformation to flourish; misleading structure‐function and health‐claims now abound on supplement labels. Meanwhile, college students tend to be open to experimentation and exploration. Hence, this study’s objective was to discover if students at USU are being influenced by such claims to unjustifiably take dietary supplements in a manner which hinders the development of healthy eating habits. During August of 2009, 1,300 USU freshmen were invited to voluntarily participate in an on‐line survey concerning dietary patterns which included a section about dietary supplementation. Five‐hundred‐and‐twelve completed the survey after providing informed written consent to participate. The …

The link between caloric intake and body fat distribution, as well as the link between calcium and vitamin D intake and bone density was also evaluated.

Methods: Participants were 8 female collegiate athletes from the USU track team. A 3-day diet history was obtained from each participant and body fat test were performed using both the BODPOD and the DEXA scans within a four month period due …

Perspectives On The Interpreting Program At Logan Regional Hospital And Access To Health Care Throughout The Spanish-Speaking Community Of Cache Valley, Danielle Babbel

Undergraduate Honors Capstone Projects

Language barriers can greatly affect patient-physician interactions, and thus have implications for individual health outcomes. This study uses surveys distributed to Spanish speakers throughout Cache Valley to solicit their views on the interpreting program at Logan Regional Hospital. The surveys reveal whether or not language related issues prevent individuals from seeking medical attention as a part of a routine check up as well as for illness care. Survey results indicate how well known the existence of the interpreting program is throughout the target community, and if the availability of a qualified interpreter increases the likelihood that individuals will seek medical …

Acyl Homoserine Lactone Signaling In Pseudomonas Chlororaphis 06, Anna Hegsted

Undergraduate Honors Capstone Projects

Pseudomonas chlororaphis (PcO6), a rhizosphere bacterium, is important to agriculture because of its use as a biological control against fungus and other pests. This biological control correlates with production of phenazines; a process regulated by acyl homoserine lactones (AHSLs). Long chain AHSLs might also have an affect on the production of phenazines. My research showed that PcO6 produced long chain AHSLs and that production is affected by nutrition with more long chain AHSLs produced in rich medium than minimal medium. The nutritional studies and findings with different mutants of PcO6 altered in phenazine production suggest that control of these antifungal …

Significant Interactions With The Most Commonly Used Herbal And Nonherbal Supplements Impact Warfarin Safety And Efficacy, Brittany Jean Sagers

Undergraduate Honors Capstone Projects

Background: Nearly 20% of adult Americans used herbal therapies in 2007, but greater than two-thirds failed to report such use to their medical provider. Significant patient harm may occur when herbal supplements are taken in conjunction with warfarin; however, patients and medical providers may not be aware of these interactions and this may place patients at risk for life-threatening bleeds or thrombotic complications.

Methods: The authors determined the top 25 herbal and 25 nonherbal supplements used by Americans using sales data from 2008, and each product was reviewed for its potential to interact with warfarin. Electronic searches were conducted using …

To What Extent Do Local Farmers' Markets, Community Supported Agriculture Programs, And Community Gardens Help Low-Income Families Improve Access To Fresh, Local Produce?, Christy Gene Somsen

Undergraduate Honors Capstone Projects

Farmers’ Markets, Community Supported Agriculture (CSA) Programs, and Community Gardens have been developed to help farmers. Many times, they also aim to help low-income families improve access to fresh produce. Often, these programs may end up helping a larger amount of middle class families instead of lower class families. There have been many programs developed to try to better help low-income families such as the Women Infant and Children (WIC) Farmers’ Market Nutrition Program (FMNP) and allowing farmers to accept WIC Cash Value Vouchers (CVV), which allows WIC participants to buy fresh produce. Farm to School Programs have also been …

Genetic And Biochemical Studies Of Plasmid Pir52-1 In Lactobacillus Helveticus, Cody Alexander Tramp

Undergraduate Honors Capstone Projects

Lactobacillus helveticus is a species of lactic acid bacteria. These bacteria, which produce lactic acid as a major product of carbohydrate metabolism, are used industrially to produce cheese and other fermented dairy products (Ebringer et al., 2008). Many species of lactic acid bacteria also possess probiotic characteristics and when ingested potentially confer increased immune function, regulate gut microbiota, and improve digestion in the host (Reid, 2008). Genetic studies of these probiotic effects and other characteristics of L. helveticus and related species have been hindered by the lack of stably replicating plasmid vectors. Plasmid vectors for several Lactobacillus species have been …

Invisible Abuse: Utah's Response To Emotional Child Abuse, Janae Sirrine

Undergraduate Honors Capstone Projects

The very nature of emotional child abuse makes it difficult to detect and report. Nevertheless, scholars and professionals in the field of child welfare have identified emotional abuse as being equally detrimental to children as physical abuse and neglect. Many states, including Utah, have unclear definitions of emotional child abuse. The purpose of this study is to interpret how Utah has used its statute on emotional abuse in the court system and whether the current definition of emotional child abuse has given Utah’s courts enough information and direction to prosecute those who emotionally abuse children. Data was collected by researching …

The Effects Of Pediatric Acute Lymphoblastic Leukemia On Social Competence: An Investigation Into The First Three Months Of Treatment, Rachel L. Duchoslav

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Childhood cancer is the leading cause of death by disease for children under 15 years of age. Despite a growing survival rate for childhood cancer, psychological research of this population has lagged behind medical advances in treatment. The research that does exist in the psycho-oncology literature is plagued with inconsistency in conclusions and methodological limitations. Focus has been given to measuring maladaptive symptoms with few firm conclusions. Conclusions in the area of social competence of children with cancer have been considerably more reliable than in other domains. Previous research suggests that children with cancer exhibit significant difficulties in the areas …

Latter-Day Saint Religiosity And Attitudes Towards Sexual Minorities, Cory John Myler

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Existing research has revealed a robust relationship between high religiosity and negative attitudes towards sexual minorities. To date, however, there have been few studies investigating this relationship within the membership of The Church of Jesus Christ of Latter-day Saints (the LDS Church). The unique history, doctrine, and organization of this religion, along with its large size, rapid growth, and sizable influence, indicate that a study of homophobia among church members will provide additional information about the relationship between religiosity and negative attitudes. These data will shed additional light on the make-up and nature of homophobia, offer insight into the relationship …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study was conducted in order to compare and evaluate a variety of ammonia (NH₃) measurement techniques for determination of ambient gas phase concentration and evaluation of system fluxes. This was accomplished by measuring NH3 emitted from area sources within two dairies, one located in south-central Idaho and another in central California. The measurement techniques utilized included: an array of passive diffusion samplers, a single annular denuder system, a single or paired Fourier transform infrared spectrometer(s) (FTIR), a paired (upwind and downwind) set of differential optical absorption spectrometers (DOAS), and a portable wind tunnel in conjunction with a …

The Effect Of Static Stretching And Order Of Warm-Up On The Isokinetic Peak Torque Of The Knee Extensors, Eric J. Sobolewski

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purposes of these studies were to determine if an acute static stretch influenced isokinetic peak torque (IPT), and to examine if the order in which the warm up routine was performed affected peak knee extension torque. Twenty trained college male students performed maximal isokinetic knee extensions under four conditions: a control consisting of no stretching, a stretch only trial, jog then stretch, and stretch then jog conditions. Each stretch was held for a total volume of 360 s. Measurements were taken on a Biodex System 3 isokinetic dynamometer at speeds of 60º s^-1 and 300º s^-1. …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study was designed to observe the effects of selenium from plant material in sheep after a single, oral dose. Purified sodium selenite and selenomethionine were given as positive controls. The plant Symphyotrichum spathulatum (Western Mountain Aster) was collected, analyzed for selenium content, and administered orally to sheep at varying doses according to body weight. Clinical signs were observed for 7 days during which time whole blood, serum, and expired air were collected. Following euthanasia, tissues were collected for histopathological analysis and mineral analysis.

Clinical signs were less apparent than expected and included depression and mild dyspnea in sheep receiving …

Finding, Nurturing, And Instilling Hope In Family Therapy, Joseph Daniel Tschudy

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The development of a personal theory of therapy and change is an integral part of the training and educational philosophies of the Marriage and Family Therapy Program at Utah State University. This personal theory attempts to identify and explain each student's beliefs regarding the specific mechanisms by which change occurs, thus providing a therapeutic backbone from which one may integrate various interventions, ideas, concepts, and approaches to therapy. As one engages in the process of integration, it becomes critical for students to evaluate their performances. A thorough self-evaluation that includes the utilization of scientific methods leads to the development of …

Relationship Between Cognitive Reserve And Rate Of Decline In Alzheimer’S Disease: A Population Study, Katherine Treiber

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

According to the theory of cognitive reserve, cognitively enriching aspects of life experience (e.g., education, occupation, and leisure activity) foster the development of more efficient neural networks and cognitive strategies, enabling individuals to cope more effectively with the pathology of dementia. Using extant data from a population-based study, we examined: (1) the effect of reserve accrued through middle life on course of neuropsychological decline; and (2) the role of ongoing engagement in mentally stimulating leisure activities in rate of general cognitive and functional deterioration.

In linear mixed models, level of occupational attainment did not affect rate of cognitive or functional …
