Temporality Of Risk Factors And The Gender Differential Related To Autism Spectrum Disorder Diagnosis, Donna L. Sullivan

Walden Dissertations and Doctoral Studies

Autism spectrum disorders (ASD) constitute life-long neurodevelopmental conditions. Globally, ASD risk for males remains 2 to 4 times greater than for females. Critical exposure mechanisms, their timing on ASD risk, and associations with the ASD gender differential remain elusive. The purpose of this study was to describe the relationship between preconception, pregnancy, recalled lactation practice, and infant traits, on ASD risk and the gender differential of ASD. A recently published temporal framework was adapted to study effects of maternal smoking and vitamin use, and recalled lactation practice on offspring ASD diagnosis with adjustment for preconception health and infant breathing traits. …

A Cross-Sectional Study: Dietary Micronutrient Levels In Allied Health And Nursing Students, Grisseel A. Cruz-Espaillat

Walden Dissertations and Doctoral Studies

The adequate intake of micronutrients is important to maintain optimal health and prevent nutritional disorders and chronic disease. Studies have shown that medical students often reduce self-care behaviors and lack adequate dietary intake, leading to nutritional deficiencies. In this quantitative cross-sectional study, measurements of micronutrient levels in a sample of allied health and nursing students were compared to Recommended Daily Allowance (RDA) values. NutritionQuest Data-on-Demand System was used to analyze nutrients and food group intake. The postpositivist paradigm was used to examine how the independent and dependent variables relate to each other. Using a one-sample t test, a comparison of …

Implementing Relationship Based Care In An Emergency Department, Ruthie Waters Rogers

Walden Dissertations and Doctoral Studies

When patients and families come to the emergency department seeking medical attention, they come in with many mixed emotions and thoughts. The fast paced, rapid turnover of patients and the chaotic atmosphere may leave patients who visit the emergency department with the perception that staff is uncaring. The purpose of this project was to implement a patient care delivery model, relationship-based care, in the emergency department. The model is comprised of several caring theories including Jean Watson's model of human care and Kristen Swanson's middle range theory of caring. The main goals of the project were to help staff enhance …

The Impact Of Caring For Seniors On The Caregiver's Stress Level, Georgina Ugochi Njoku

Walden Dissertations and Doctoral Studies

The number of Canadian seniors with 2 or more chronic health conditions living into their late 90s or older has never been greater. As such, concerns have been raised that the Canadian healthcare system will be unable to meet the growing healthcare needs of the aging population. In this project, an Advanced Practice Nursing needs assessment was used to identify the impact that caring for a senior has on caregivers' stress levels, and what resources caregivers need to in order to cope with their role. Guided by Neuman's system model theory and Rogers' diffusion of innovation model, a convenience sampling …

Self-Efficacy, Cultural Competence, And Perception Of Learning Environment In Traditional And Interprofessional Education Physical Therapy Curricula, Laura Smith

Walden Dissertations and Doctoral Studies

Interprofessional education (IPE), a concept that brings students from different health care professions together in the learning process, has been adopted by some physical therapy (PT) schools as an alternative to traditional PT-only curricula. Both approaches have the goal of improving patient outcomes for an increasingly diverse population. There was a void in the research comparing IPE and traditional curricula in PT education. Grounded in the theoretical frameworks of adult and social learning theory, the purpose of this study was to examine differences in students' self-efficacy, cultural competence, and perceptions of the learning environment based on curricular type and prior …

Mental Health Disorders As Predictors Of Relapse In Previously Detoxified Individuals, Toni Lee Simonson

Walden Dissertations and Doctoral Studies

Researchers have shown a relationship between mental health disorders and alcohol dependence. However, only 5-10% of individuals with substance use problems co-occurring with mental health problems are correctly identified. The purpose of this research was to identify predictors of relapse using three different instruments of varying complexity: the Patient Health Questionnaire-9 (PHQ-9), the Modified Mini Screen (MMS), and the Millon Clinical Multiaxial Inventory-III (MCMI-III). Researchers have found that using alcohol produces relief, similar to a pharmacological intervention, from troublesome mental health symptoms that individuals experience. Considering this association, the self-medication hypothesis was the conceptual lens used for the study as …

Midcareer Women Leaving Information Technology: An Examination Of The Phenomenon, Susan F. Way

Walden Dissertations and Doctoral Studies

Midcareer women are leaving the information technology (IT) career field at a much higher rate than are men. This attrition has contributed to a decreasing percentage of women in the IT field, hindering the creativity, innovation, and productivity that can result from a diverse workforce. This phenomenological study addressed a gap in the current research by examining the lived experience of women who have left the IT field. The conceptual frameworks of the study included Rhodes and Doering's integrated career change model based on traditional turnover theory, a model of gender and power in careers by Ragins and Sundstrom, and …

The Association Of Lead With Cataracts And Vision-Related Problems In Perimenopausal Women, Imogene Drakes

Walden Dissertations and Doctoral Studies

Around the world, women are subject to an earlier incidence of cataracts, have a higher risk for cataracts, and also have a higher risk for other vision-related problems than men. Previous research has indicated an association between endogenous lead stored in long bones and cataracts in men over 60 years of age; however, a similar study in women did not reveal an association. This case control study was conducted to investigate whether perimenopausal mobilization of endogenous lead serves as a possible causative factor for women's generalized vision issues and cataract incidence in particular. Secondary data were gathered from 1,416 women …

Global Response To Local Problems:The Global Health Community Response To The Ebola Outbreak Of 2014, Nicole Thelen

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Health crises are often met with much support from the global health aid communities, who strive to contain the current health crisis and improve the conditions of the affected society. The recent Ebola outbreak of 2014 is no exception. Driven by public panic and media coverage, the global health community responded in force, dispatching aid organizations, monetary help, and military assistance to both assist those affected with the disease and prevent it from spreading. The World Health Organization, along with Doctors without Borders and many other global organizations, swept in to provide aid to the affected areas. This project examines …

Obesity Surveillance In Childhood, Jessica Garcia

Walden Dissertations and Doctoral Studies

Current practice behaviors for obesity management have remained refractory. Research has shown that lack of time and poor training/skills by primary care providers has led to poor or absent obesity counseling in practice. The purpose of this intervention was to facilitate obesity counseling in a pediatric office by using an evidence-based model called the 5As model of behavioral change. Lewin's change theory was the framework for this project to help clinicians transition their practice to include the 5As model in practice. The project consisted of a 30-minute power point presentation that included 2 case samples demonstrating how the 5As would …

Liver Perilipin 5 Expression Worsens Hepatosteatosis But Not Insulin Resistance In High Fat-Fed Mice, Michelle B. Trevino, David Mazur-Hart, Yui Machida, Timothy King, Joseph Nadler, Elena V. Galkina, Arjun Poddar, Sucharita Dutta, Yumi Imai

Mathematics & Statistics Faculty Publications

Perilipin 5 (PLIN5) is a lipid droplet (LD) protein highly expressed in oxidative tissues, including the fasted liver. However, its expression also increases in nonalcoholic fatty liver. To determine whether PLIN5 regulates metabolic phenotypes of hepatosteatosis under nutritional excess, liver targeted overexpression of PLIN5 was achieved using adenoviral vector (Ad-PLIN5) in male C57BL/6J mice fed high-fat diet. Mice treated with adenovirus expressing green fluorescent protein (GFP) (Ad-GFP) served as control. Ad-PLIN5 livers increased LD in the liver section, and liquid chromatography with tandem mass spectrometry revealed increases in lipid classes associated with LD, including triacylglycerol, cholesterol ester, and phospholipid classes, …

Inhibition Of Toxic Iapp Amyloid By Extracts Of Common Fruits, David A. Moffet, Pei-Yu Kao, Evangeline Green, Catalina Pereirab, Shauna Ekimura, Dennis Juarez, Travis Whyte, Taylor Arhar, Bianca Malaspina, Luiza A. Nogaj

Chemistry and Biochemistry Faculty Works

The aggregation of the 37-amino acid polypeptide islet amyloid polypeptide (IAPP, amylin), as either insoluble amyloid or as small oligomers, appears to play a direct role in the death of pancreatic β-islet cells in type 2 diabetes. It is believed that inhibiting the aggregation of IAPP may slow down, if not prevent entirely, the progression of this disease. Extracts of thirteen different common fruits were analyzed for their ability to prevent the aggregation of amyloidogenic IAPP. Thioflavin T binding, immuno-detection and circular dichroism assays were performed to test the in vitro inhibitory potential of each extract. Atomic force microscopy was …

Moderate Altitude Affects High Intensity Running Performance In A Collegiate Women's Soccer Game, William Mccormack

Health and Human Sciences Faculty Works

The effect of altitude on soccer game activity profiles was retrospectively examined in six NCAA Division I female soccer players. Comparisons were made between two matches played at sea level (SL) and one match played at a moderate altitude (1839 m). A 10-Hz global positioning system device was used to measure distance and velocity. The rate of total distance capacity (TDC) and high intensity running (HIR) as well as percent of time at HIR were evaluated. Significant differences were seen in the distance rate (120.55 ± 8.26 m·min-1 versus 105.77 ± 10.19 m·min-1) and the HIR rate (27.65 ± 9.25 …

Compassion Development In Higher Education, Roxanne Rashedi, Thomas G. Plante, Erin S. Callister

Psychology

Many schools of psychology and religious studies intend to promote the cultivation of compassion. Compassion is currently an integral area of study in psychology, religious studies, and higher education, specifically in faith-based higher education. While secular universities in the United States strive to generate disciplinary-based knowledge through scholarship, their ability to promote students' use of the information they are learning to create positive social change has typically lagged. Conscious of the magnitude of today's global issues and dissatisfied with the current disparity between the world's reality and university curricula, scholars have begun to re-imagine the role of higher education in …

Background and Objective. Advances in technology are providing new forms of human–computer interaction. The current study examined one form of human–computer interaction, augmented reality (AR), whereby subjects train in the real-world workspace with virtual objects projected by the computer. Motor performances were compared with those obtained while subjects used a traditional human–computer interaction, that is, a personal computer (PC) with a mouse. Methods. Patients used goal-directed arm movements to play AR and PC versions of the Fruit Ninja video game. The 2 versions required the same arm movements to control the game but had different cognitive demands. With …

The Psychological Resilience Of Spousal Caregivers Of Multiple Sclerosis Family, Marisa Diane Diaz

Walden Dissertations and Doctoral Studies

The purpose of this quantitative study was to examine an under-researched topic: the relationship between psychological resilience and personal growth with spousal caregivers of patients diagnosed with Multiple Sclerosis (MS). Chronic illnesses contribute to potentially stressful changes (i.e., lifestyle, quality of life, financial wellbeing, and interpersonal relationships) for the caregiver. The theoretical foundation for this study was Walsh's family resilience theory, which contends that resilience is vital for coping with stressful life experiences and leading a more successful life. Three separate analyses were conducted to examine the relationship between the total scores of the RS and the PGIS, the SWLS, …

Low Level Lead Exposure And Inflammatory Markers In The Brains Of C57bl/6j Mice, Miguel A. Cervantes

Open Access Theses & Dissertations

Background and Significance: Prior studies have indicated that early chronic low-level lead exposure may be associated with adverse effects on motor and cognitive functions. The mechanisms by which low-level lead affects brain function are unknown. Objectives: The current study aimed to (1) determine whether early chronic low-level lead exposure altered the expression of pro- or ant-inflammatory cytokines and markers of oxidative stress in mouse brain studied at two ages, pre-adolescence (PND 28) and early adulthood (PND 40); and (2) in the same pre-adolescent and early adulthood mice, compare and contrast the levels of pro- or ant-inflammatory markers in three brain …

The Association Between Dietary Sodium, Salt, And Elevated Blood Pressure Among Hispanic Adults In El Paso, Texas, Cynthia Chacon

Open Access Theses & Dissertations

Introduction: High blood pressure (hypertension) is the leading cause of cardiovascular disease (CVD) which represents a worldwide public health concern, and continues to be the number one cause of death among both men and women affecting 1 out of 3 adults in the United States. Furthermore, there is evidence suggesting that high levels of dietary sodium and salt consumption intake can not only increase an individual's blood pressure level, but also their risk for CVD, heart attack, or stroke. Objective: To conduct a secondary data analysis to assess the association between sodium and salt intake and blood pressure among Hispanic …

Serine Palmitoyltransferase And Giardial Encystation, Monica Delgado

Open Access Theses & Dissertations

Giardia lamblia is a flagellated protozoan parasite responsible for chronic diarrheal disease in humans and animals. Giardia has minimal lipid synThesis machinery and the majority of its lipids are obtained from the small intestine of humans where the trophozoites colonize. Recent results from our laboratory indicate that sphingolipids (SLs) are also important for Giardia and they regulate encystation and cyst production. Only five SL genes are present in this parasite and they are differentially regulated during encystation. In my studies, I found that giardial serine palmitoyltransferase (gSPT) activity is upregulated in encysting cells, suggesting it might play an important role …
