A Behavioral And Neuroimmune System Model Of The Effects Of Chronic Low-Level Lead Exposure In Young Male C57bl/6j Mice, Mayra Gisel Flores-Montoya

Open Access Theses & Dissertations

Chronic low-level lead exposure reduces memory in children however the brain mechanisms mediating these effects are not known. In previous studies we showed that early lead exposure reduced olfactory memory and exploratory behavior in young mice, and reduced microglia cell density in hippocampus/dentate gyrus. The present studies aimed to identify additional behavioral tests that were sensitive to early low-level lead exposure in young mice; and to examine whether microglia upregulated factors known to promote cell migration. Seventy-two C57BL/6J male mice were exposed to 0 ppm (controls), 30 ppm (low-dose), or 430 ppm (high-dose) of lead acetate via dams' milk from …

Validating The Accuracy Of A Language Screening Instrument In Identifying Preschool Children In El Paso, Texas, Roxana Stubbemann

Open Access Theses & Dissertations

Background: Effective screeners are time and cost effective and may be an efficient indicator of whether a child needs further in-depth assessment. Surveyed Speech-Language Pathologists in the El Paso, TX region report using informal screening tools such as observational measures and checklists due to the lack of adequate standardized tools that suit the needs of bilingual children, which occupy a majority of their caseloads (Curtis, Summers, Smith, & Stubbemann, 2016). Many language-screening instruments are not psychometrically sound for culturally and linguistically diverse (CLD) populations and limited research exists on the accuracy of these tools.

Purpose: The purpose of this study …

Studies Of Air Pollutants And Their Impact On Respiratory And Cardiovascular Diseases In The El Paso Del Norte Region With Emphasis On Mobile Emissions, Juan Gustavo Arias Ugarte

Open Access Theses & Dissertations

Air pollution may cause different diseases, such as cardiovascular and lung diseases. Traffic is a major source of mobile emissions causing air pollution. Exhaust emissions from mobile sources (Emissions of Carbon Monoxide, Nitrogen Oxides and Hydrocarbons) and Non-exhaust (Brake and Tire) are complex mixtures of gases and dust, including a large number of ultrafine particles, especially in areas with high traffic density. Recent studies have shown high rates of morbidity and mortality in people exposed to these types of emissions because the fine and ultrafine particles can be transported from the respiratory airways to the organs, thus contributing to increase …

Evaluation Of Pertussis Knowledge Within The Child Daycare Staff And Management In The El Paso, Texas, Diana Jaqueline Gomez

Open Access Theses & Dissertations

BACKGROUND: Child daycare centers have an enormous influence on the children's health, which is important to maintain daycare staff and management informed on how to prevent communicable diseases, such as pertussis. Bordetella pertussis (Bp), the causative agent of whooping cough, is a small gram-negative bacterium that infects the nasopharynx of humans, which are the only reservoir. Bp is a highly contagious respiratory disease, which continues to be a severe disease in infants. The disease affects all ages and is easily transmitted from person to person, through respiratory droplets. Even though there is a vaccine available for all ages there are …

The Use Of Code-Switching In Bilingual Children With Autism Spectrum Disorder, Monica Yolanda Ponce-Lawler

Open Access Theses & Dissertations

Abstract

Background: Code-switching may be seen as a weakness in the eyes of many who do not truly

understand bilingualism. Several professionals consider code-switching to be a compensatory

strategy, however other professionals perceive code-switching as a functionally motivating behavior

(Chung, 2006). Whether is it consciously or subconsciously that a child code-switches, there is

limited research on when bilingual children with Autism Spectrum Disorder (ASD) are likely to

code-switch as well as what patterns they utilize when they code-switch.

Purpose: To grow the limited research on the use of code-switching in bilingual children with ASD.

Introduce and compare two language treatments; …

Parental Understandings Of The Meaning Of Autism Spectrum Disorder (Asd), Kylara Leyva

Open Access Theses & Dissertations

This study examines how parents understand autism, their child's behavior and development. Parents can understand their child's behavior and development through a medical model perspective, which sees the childâ??s autism as a series of deficits and deviations. However, a growing number of parents understand their child's behavior and development through a neurodiversity perspective, where a child is seen as having differences in behavior, instead of deficits. Parents' understandings of autism can influence how they see their child's behavior and development and be a driver for seeking diagnosis. In-depth interviews were conducted with parents of children with autism to probe for …

Evaluation Of A Gender-Relevant Physical Activity After-School Program, Vianay Lopez

Open Access Theses & Dissertations

Background: Physical activity rates have decreased in the past 30 years. Physical activity rates decline further among girls as they reach adolescence, yet studies suggest girls are more inclined to participate in moderate-to-vigorous physical activity (MVPA) while among peers. When in close social networks, girls who have more physically active friends report being more active themselves. Several mentor-based programs throughout the United States have increased physical activity among preadolescent girls, indicating that gender-relevant physical activity programs may reverse their declining rates of physical activity.

Purpose: To evaluate if participation in a gender-relevant physical activity after-school program influenced participants' aerobic fitness, …

Instilling Positive Beliefs About Organ Donation: An Information Processing Approach, Gerardo Jose Moreira

Open Access Theses & Dissertations

The number of those seeking a kidney donation in the United States continues to increase while the number of donors is not growing at the same rate (U.S. Department of Health and Human Services USDHHS, 2010). The lack of donations is more prevalent in low health literate communities which suffer from misinformation and ultimately negative beliefs toward organ donation. Thus, it is important to understand how marketing efforts can effectively change individuals' beliefs about organ donation.

Drawing on the Self-Determination Theory and Schema Theory, I proposed that the effectiveness of health education programs, which is to motivate individuals to be …

Healthcare Utilization Awareness And Labor Monitoring Methodology: A Theoretical I.M.S.E. Approach To Risk Minimization And Human Metrics Capturing In The Nursing Workforce, Luis Reyes

Open Access Theses & Dissertations

The healthcare industry is so complex and dynamic that the development of any tool designed to promote positive patient outcomes nearly requires the developer to be an actual healthcare practitioner. Many healthcare tools exists that initially give the perception that there will be no future requirements that may hinder the tools' integrity, but more often than not, the unexpected occurs. The future is one unpredictable element of life that most engineers wish they could capture with optimal precision. I.M.S.E. (Industrial, Manufacturing and Systems Engineering) applications do not assist with fortune telling, but they do assist with creating robust tools designed …

Language Of Intervention In A Bilingual Child With Autism, Amelie Muzza

Open Access Theses & Dissertations

This study was conducted to address language of intervention for the rapidly-growing bilingual population of children with Autism Spectrum Disorder (ASD) in the United States. The purpose of this study was to determine whether a monolingual English or bilingual Spanish/English condition would yield a greater number of request types in a 3-year-old bilingual participant with autism. A single-subject, rapid alternating treatments design with baseline and a final maintenance phase was used to alternate between monolingual English and bilingual Spanish/English interventions. Results did not meet the criteria set for continuation of treatment in either condition; therefore, both monolingual and bilingual interventions …

Evaluation Of A Nutrition Education Program Targeting Home-Based Child Care Centers, Cassandra Nicole Urrutia

Open Access Theses & Dissertations

Background: The development of a highly obesogenic culture promoting sedentary behavior and the consumption of calorie-dense foods has led to increased levels of overweight and obesity globally. While children and adults are both at increased risk of developing obesity, the risk is even higher in minority and low socioeconomic populations. Changes in familial structure and an increase in mothers of younger children (below the age of 6) entering the workforce have created a new demand for child care services. Although some studies have researched the effectiveness of nutrition programs to increase healthy eating within the child care setting, few have …

Monitoring And Blunting Coping Style Effects On College Student Processing Of Health Information Via Social Media, Katherine Marie Aguirre

Open Access Theses & Dissertations

The dissemination of public health messages via social media is a growing phenomenon that is changing the health communication landscape (Chou, Hunt, Beckjord, Mojer, & Hesse, 2009). Few studies have investigated how individuals process health-threatening information. This study addressed this gap in knowledge. Specifically, the current study investigated the impact of coping style on an individual's attention to health-threatening and health-promoting words on an attention task. The current study also investigated the impact of coping style on the recall of health-threatening, health-promoting, and neutral words contained in a diabetes health message. In addition, the current study investigated if coping style …

Background: Mosquito borne diseases are the cause of many different disease syndromes and deaths in animals, both wild and domesticated, and humans of all ages and ethnicities. Though El Paso, TX is located in an arid region, mosquito populations are still rapidly growing in urban and agricultural communities and so are the mosquito borne illnesses. The most common vectors associated with mosquito borne illnesses in El Paso County are Culex quinquefasciatus, Culex tarsalis, and Aedes aegypti. Vector management is often the primary option to prevent and control outbreaks of mosquito borne illnesses and very often utilize fogging as the primary …

Evaluating The Impact Of A High School Garden In El Paso, Texas For Fruit And Vegetable Intake Using A Valid Biomarker, Patrick Vaughn Hopkins

Open Access Theses & Dissertations

Background: School gardens are an educational tool used to increase children's exposure to, and intake of, fruits and vegetables (F/V). Diets rich in F/V reduce the risk of heart disease, stroke, some cancers, and type 2 diabetes, and can aid in weight management as a strategy to reduce obesity prevalence. Objective data of the impact of school gardens on F/V intake are lacking, as most studies have relied on dietary self-reporting to validate F/V intake. Self-reporting of dietary intake is inherently an unreliable method for assessing F/V intake. Carotenoids, a family of phytochemicals, are a reliable biomarker of dietary intake …

Optimization Of Collagen Microneedle Using Taguchi Method, Abhilash Aditya

Open Access Theses & Dissertations

Research is conducted to create dissolving collagen microneedles and to optimize the parameters for close to perfect dimension microneedles. A collagen microneedle patch has been developed with a micro-manufacturing process (micro-molding process). The collagen microneedles, varying in length from 300 to 600-μm may reach different targeted layers of the skin depending on the application. As the microneedles penetrate the skin they dissolve, delivering collagen through the epidermis. Such addition of collagen directly to the dermis layers allows it to be absorbed, increasing skin's strength and resilience, since it is one of the natural components of the younger looking skin. This …

Open Access Theses & Dissertations

Multiple studies have found yoga practice to be effective in improving glucose control and other health markers of adults with type 2 diabetes mellitus (T2DM). However, current findings cannot reach a consensus given multiple methodological inconsistencies. The primary purpose of this Dissertation work was to investigate the impact of yoga practice on the glucose control of participants with T2DM through two different approaches in two separate exploratory studies. The first study, a quasi-experimental design, examined the effect of eight weeks of yoga practice on glucose control taking into account previous limitations in the literature. The second study, a single-subject design, …

An Environmental Scan Of Diagnostic Practices For Children With Disabilities In El Paso, Alezandra Martinez

Open Access Theses & Dissertations

With the prevalence of developmental disabilities in the rise in the United States, it is important that these children are identified and diagnosed as soon as possible so that they may receive appropriate medical treatment and intervention. However, research suggests that there are several factors that influence screening, referral, and diagnostic practices. This study aimed to analyze key themes that arose when parents of children with disabilities and pediatric healthcare providers discussed screening, referral, and diagnostic practices for children in El Paso, a medically underserved community. Researchers conducted a 2- phase study that employed both quantitative and qualitative methodology. Results …
