Home-Based Primary Care: A Return Of The House Call, Nicole M. Windjue

Theses and Dissertations

Retention and recruitment of providers is an ongoing stmggle in small and rural communities and poses a significant public health concern in meeting the needs of our aging population. This unfortunate situation will force many of our aging adults and home bound elders out of their homes and into skilled nursing facilities or assisted living environments long before they would have otherwise required skilled care. Providing primary care visits in the home is one way of addressing this issue. The medical and nursing communities have an obligation and a difficult challenge in providing our aging elders with a continuity of …

Human Sperm Dna Oxidation, Motility And Viability In The Presence Of L-Carnitine During In Vitro Incubation And Centrifugation, S. Banihani, R. Sharma, Mekki Bayachou, E. Sabanegh, A. Agarwal

Chemistry Faculty Publications

In vitro incubation and centrifugation is known to decrease human sperm quality. In the human body, besides its antioxidant effects, l-carnitine (LC) facilitates the transport of activated fatty acids from the cytosol to the mitochondrial matrix. In this study, we investigated the effect of LC on human sperm motility, viability and DNA oxidation after incubation and centrifugation, following the sperm preparation protocols of assisted reproduction. Normozoospermic semen samples (n = 55) were analysed according to the World Health Organization (WHO) guidelines. LC concentrations that are not toxic to spermatozoa as determined by sperm motility and viability were standardised after 2 …

Cattle Browsing Sagebrush Steppe During Fall: Effects On Plant Community Structure And Influence Of Experience On Cattle Foraging Behavior And Body Weights, Charles A. Petersen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Historic and repetitious spring grazing by livestock, combined with altered fire regimes, has increased the density and abundance of big sagebrush and reduced the frequency of perennial grasses and forbs on many western landscapes. Periodic disturbance is critical for maintaining and improving sagebrush ecosystems. Compared with traditional disturbances – chemical, mechanical, and fire – strategic grazing with livestock offers several benefits. They include creating locally adapted cattle that can rejuvenate sagebrush steppe, which reduces costs associated with mechanical and chemical rejuvenation treatments and feeding cattle during winter, the major cost of ranch operation.

I evaluated the practicality of strategically timed …

Using The Framingham Risk Score To Evaluate Immigrant Effect On Cardiovascular Disease Risk In Mexican Americans, Jennifer J. Salinas, Bassent Abdelbary, Jeffrey Wilson, Monir Hossain, Susan P. Fisher-Hoch, Joseph B. Mccormick

Physician Assistant Studies Faculty Publications

Background—This study uses the Framingham Risk Score (FRS) for 10-year cardiovascular disease (CVD) to evaluate differences between Mexican American immigrants and the U.S.-born population. Methods and Results—Data from the Cameron County Hispanic Cohort (N=1,559). Average total risk scores were generated by age group for each gender. Regression analysis was conducted adjusting for covariates and interaction effects. Both women and men in the CCHC sample who were long-term immigrant residents (mean FRS scores women 4.2 with p<.001 vs. men 4.0 with p<.001) or born in the U.S. (mean FRS scores women 4.6 with p<.001 vs. men 3.3 with p<.001) had significantly higher risk scores than immigrants who had only been in this country for less than 10 years. The interaction model indicates that differences between immigrant and native-born Mexican Americans are most greatly felt at lowest levels of socioeconomic status for men in the CCHC. Conclusions—This study suggests that in terms of immigrant advantage in CVD risk, on whom, where, and how the comparisons are being made have important implications for the degree of difference observed.

The Manufacture Of Lifestyle: The Role Of Corporations In Unhealthy Living, Nicholas Freudenberg

Publications and Research

Recently, researchers have debated two views on the connection between lifestyle and health. In the first, health-related lifestyles including tobacco and alcohol use, diet, and physical activity are seen as primary influences on health. In the second, social stratification is the dominant influence with lifestyles simply markers of social status. Neither approach leads to interventions that can reverse the world's most serious health problems. This article proposes that corporate practices are a dominant influence on the lifestyles that shape patterns of health and disease. Modifying business practices that promote unhealthy lifestyles is a promising strategy for improving population health. Corporations …

Genetic Polymorphisms In The Folate Metabolizing Pathway And Breast Cancer Survival., Nandita Das

Electronic Theses and Dissertations

Genes in folate metabolizing pathway are responsible for modulating key enzymes in folate metabolisms necessary for DNA synthesis and repair and influence DNA methylation. Irregularity in DNA methylation may modify tumor phenotype response to chemotherapy and abnormal DNA synthesis, and repair may lead to carcinogenesis. This dissertation project tested the hypothesis that the key genes in the folate metabolizing pathway, namely Methylenetetrahydrofolate reductase (MTHFR) , betaine-homocysteinemethyltransferase (BHMT) , 5-methyltetrahydrofolate-homocysteine (MTR), 5-methyltetrahydrofolate-homocysteine methyltransferase reductase (MTRR) , and serine hydroxymethyltransferase (SHMT1) and folate receptor 1 (FOLR1) influences all- cause and breast cancer-specific mortality and the association between the genes in the folate …

A Study Of The Link Between Partial Sleep Deprivation And Obesity, Jennifer Pacheco

Honors College Theses

Obesity has become a major health problem with increasing prevalence and is related to multiple medical consequences, such as increased risk for diabetes, heart disease, arthritis, and cancer (Hasler et al., 2004). Due to the limited availability of effective treatment of weight problems, it is necessary to identify potential risk factors for obesity. One factor that has received increased attention is chronic partial sleep deprivation (<7 hours of sleep a night). The decrease in average sleep duration over the past three to four decades has occurred simultaneously with the increase in the prevalence of obesity. Chronic partial sleep deprivation could be a possible risk factor for obesity, but current understanding of the processes linking sleep deprivation to obesity is incomplete. The research will focus on examining the possible pathways through which partial sleep deprivation contributes to the development of obesity: alterations in metabolic pathways and waking behavior, including eating behavior and physical inactivity. The hypothesis behind the proposed study is that increasing sleep duration in obese individuals who experience partial sleep deprivation will lead to a decreased BMI. Research addressing the possible pathways and targeting the amount of sleep will benefit individuals in preventing and/or treating obesity.

Climate Change, Environmental Degradation, And Migration: A Complex Nexus, Mostafa Mahmud Naser

William & Mary Environmental Law and Policy Review

The individual or combined effects of climate change are likely to trigger mass human movement both within and across international borders. The United Nations High Commissioner for Refugees (“UNHCR”) predicts that between 50 and 200 million people may be displaced by 2050. Thus, the human impact on the environment is creating a new kind of global casualty for the twenty-first century—an emergent class of environmental migrants. The exact number of individuals cannot be predicted as scholars and international agencies provide varying statistics depending on underlying methods, scenarios, time frames, and assumptions. Many authors challenge the concept of climate change as …

Mother Knows Best: The Rhetorical Persona Of Michelle Obama And The "Let's Move" Campaign, Monika Bertaki

UNLV Theses, Dissertations, Professional Papers, and Capstones

Some first ladies are often condemned for being too involved with the presidents' power in politics while other first ladies find themselves condemned for the lack of involvement. First ladies, it seems, are damned if they do and damned if they don't. Consequently, Michelle Obama faces rhetorical problems that in some respects are similar to those of previous first ladies and in other respects are quite different. Along with the criticisms encountered by previous presidential wives, Obama faces the stereotypes African American women have endured since the inception of the nation. Michelle Obama's "Let's Move" campaign serves as a rhetorical …

You Should Know Jack: A Qualitative Study Of The Jack Lalanne Show (1951-~1965), Robert Cochrane

UNLV Theses, Dissertations, Professional Papers, and Capstones

Jack LaLanne hosted the first and longest running fitness program in United States broadcast history from 1951 through 1985. Since LaLanne's rise as a broadcasting celebrity, the health and fitness industry has grown from a small, somewhat-maligned field into a multi-billion dollar per year economy of its own. As LaLanne reached iconic status through his show, his name became synonymous with good health and nutrition, but the messages of his show went far beyond simple exercises. He used religious, patriotic, and biomedical messages to get his points across. In addition, he was a showman who sang to his audience, used …

The Relationship Between Self-Efficacy And Fluid,And Dietary Compliance In Hemodialysis Patients, Ansy Paul John

UNLV Theses, Dissertations, Professional Papers, and Capstones

Patients with end-stage renal disease (ESRD) who receive hemodialysis often fail to follow a prescribed diet and fluid regimen, which undermines the effectiveness of care and leads to unpredictable disease progression and greater likelihood of complications. Non-adherence to dietary and fluid limitations compromises the outcomes of patients receiving hemodialysis. Noncompliance can lead to detrimental long-term outcomes including deterioration of the cardiovascular system, heart failure, hypertension, and pulmonary edema as well as short-term problems such as edema, itching, bone pain, and breathlessness.

Many studies have demonstrated that self-efficacy strategies are associated with improved dietary and fluid compliance among individuals receiving hemodialysis. …

Nutritional Management Of The Extremely Low Birth Weight Infant: An Evidence Based Clinical Practice Guideline, Dana J. Lunde

UNLV Theses, Dissertations, Professional Papers, and Capstones

Premature birth has risen steadily over the last decade resulting in an increased number of infants needing neonatal intensive care. The demand for neonatal intensive care has lead to many improvements in the delivery of such care with an increase in the survival of the smallest and most premature infants. However, most of these infants are being discharged from neonatal intensive care units (NICU) with severe extrauterine growth restriction (EUGR).

Extremely low birth weight (ELBW) infants born at 23-27 weeks gestation and who have a weight of less than 1,000 grams are at the highest risk for EUGR because of …

Spawning, Veliger Growth And Desiccation Of Dreissena Bugensis, Lynn Schwaebe

UNLV Theses, Dissertations, Professional Papers, and Capstones

Quagga (Dreissena bugensis) mussel veliger growth was compared under two dietary conditions: 1) only seston present in Lake Mead water; and 2) Lake Mead seston plus algae (Isochrysis galbana). Shell length, width, and area were compared as a function of time for the two treatments. It was expected that mussels would exhibit faster growth when supplemented with I. galbana than with Lake Mead water alone. However, no significant difference was observed between the control and I. galbana treatments. This result was unexpected and may have been caused by water quality, the nutritional content of Lake Mead seston, and/or over feeding. …

The Acute Effect Of Endurance Exercise On Lipoproteins Measured By Nuclear Magnetic Resonance (Nmr) In Healthy Men, Hanaa Adnan Shaheen

UNLV Theses, Dissertations, Professional Papers, and Capstones

Background: Cardiovascular disease (CVD) represents a major cause of death in the United States, with abnormal levels of blood lipids and physical inactivity considered as major modifiable risk factors. The conventional lipid profile has been used to assess for CVD risk by directly measuring the concentrations of blood lipids. However, lipoprotein particle size and number obtained from a novel method, Nuclear Magnetic Resonance (NMR) may also asses for CVD risk with greater sensitivity. Exercise and increased physical activity has been shown to produce favorable effects on blood lipids and consequently reduce CVD risk. To understand this effect, it is important …

Use Of Continuous Glucose Monitors In Type-1 Diabetes: An Analysis Of Wave Form Versus Glycemic Values In The Improvement Of Glucose Control And Fear Of Hypoglycemia, Tomas Charles Walker

UNLV Theses, Dissertations, Professional Papers, and Capstones

Type-1 diabetes is a disease of subtle complexities. Patients struggle to understand glucose patterns and their responses to insulin or food intake while maintaining hectic lifestyles. Minor misjudgments in treatments can result in disastrous consequences with significant hypo- or hyperglycemic excursions.

Despite improvements in technologies available for diabetes management, including home monitoring of blood glucose, more predictable insulin therapies, and improved insulin delivery via insulin pump, the average HbA1c has remained relatively unchanged. Poor diabetes control is recognized as contributing to long-term diabetes comorbidities including neuropathy, nephropathy, retinopathy, and micro- and macrovascular disease.

Real-time continuous glucose monitors, such as the …

The Nation Before Taste: The Challenges Of American Culinary History, Andrew P. Haley

Faculty Publications

Food is material and familiar, and because it is, we are often overconfident about our ability to understand the culinary past. It is easy to believe that if we can discover the recipe for some forgotten dish, the history of the dish becomes intelligible. When it does not, it tempts those who consume culinary history to impose modern sensibilities on our predecessors. The Nation before Taste" argues that historians and museum curators must be especially vigilant when presenting the history of food. Reviewing a series of historical challenges that stemmed from studying the United States in the late nineteenth and …

Formation Of Embryoid Bodies From Human Embryonic Stem Cells In Defined Medium, Ashley Kiene

Biological and Agricultural Engineering Undergraduate Honors Theses

Embryonic stem cells have the characteristic of self-renewal and the ability to differentiate into tissues from all three germ layers. Many times, the first step in using human embryonic stem cells for regenerative medicine is often initiated by embryoid body (EB) formation. EBs are three-dimensional multicellular aggregates that resemble early post implantation embryos that still maintain the potential to form the three germ layers. Currently, generating EBs from human embryonic stem cells (hESC) that are adapted to feeder-independent medium is difficult, much more so than feeder cultured hESC. Using a chemically defined medium would not only help the application of …

Biomass Assisted Synthesis Of Antibacterial Gold Nanoparticles And Commentary On Its Future Potential And Applications In Medicine, Chad Willis

Mahurin Honors College Capstone Experience/Thesis Projects

Xylose is a natural monosaccharide found in biomass such as straw, pecan shells, cottonseed hulls, and corncobs. Using this monosaccharide, we report the green synthesis and characterization of biocompatible, biodegradable xylose encapsulated gold nanoparticles (Xyl-GNPs) with potential antibacterial activity. GNPs were synthesized using the bioreduction property of xylose on the chloroaurate anions in an aqueous solution at room temperature and at atmospheric pressure. The characterization of synthesized GNPs was examined by UV-vis spectroscopy; transmission electron microscopy (TEM), energy-dispersive x-ray spectroscopy (EDS) and fourier transform infrared spectroscopy (FTIR).

Florentine Palaces, Costly Signaling, And Lineage Survival, Michael K. Church

Anthropology ETDs

My dissertation evaluated whether the palaces built in Florence, Italy during the Renaissance are a form of costly signaling. Costly signaling theory was developed to explain why organisms have attributes and behaviors that appear to defy basic Darwinian logic by having costs that are not offset by obvious benefits. The theory proposes that such attributes and behaviors persist because they are reliable signals of information about the signalers. Signal audiences use the information content of signals to rank signalers and to modify their interactions with signalers in ways that benefit signalers. These interactions can involve mate choice, predation avoidance, status …

Obstacles To Dieting Behavior, Shahram Heshmat

Journal of Food Law & Policy

Despite documented short term success, dieting has a very low success rates, most dieters regain their weight back within 3-5 years. The question is why do people fail to stick to their goal for eating a healthy diet in order to lose weight? One possible answer is that people have self-control problems in the form of a present-biased preference. From a prior perspective, they want to behave relatively patiently, but as the moment of action approaches, they want to behave relatively impatiently. The essay presents some insights from behavioral economics to explain why people fail to maintain healthy behavior.

The Costs And Impacts Of Rising Food Prices Among Low-Income Households, Elaine Waxman

Journal of Food Law & Policy

The pressure of rising food prices on low-income households is often assumed to be primarily an issue for developing economies, where fluctuations in food staple prices can have dramatic consequences for food security and social and political stability. Observers often note that Americans benefit from relatively low food prices and spend far less to feed their families than their counterparts in many other parts of the world. Indeed, the average American household spent 7.6% of their household expenditures on food purchases at home in 2009, while the comparable percentage exceeded 40% of household expenditures in diverse countries such as Mexico, …
