UNLV Theses, Dissertations, Professional Papers, and Capstones

Purpose: Barefoot running (BF) is popular in the running community. Biomechanical changes occur with BF, especially when initial contact changes from rearfoot strike (RFS) to forefoot strike (FFS). In addition, changes in lumbar spine range of motion (ROM), particularly involving lumbar lordosis, have been associated with increased low back pain (LBP). However it is not known how changing from RFS to FFS affects lumbar lordosis or LBP. Thus, the purpose of this study was to determine if a change from RFS to FFS would change lumbar lordosis, and/or decrease shock attenuation, and/or change comfort levels in healthy recreational/experienced runners.

Therapeutic Neuroscience Education For Patients With Chronic Low Back Pain And Its Effect On Activity Level, Pain Perception, And Function, Stephen Burton, Amber Domingo, Ryan Spencer

UNLV Theses, Dissertations, Professional Papers, and Capstones

Background: Chronic low back pain (CLBP) is a significant cause of disability and inactivity in the United States. Patients with chronic pain are often symptomatic even in the absence of tissue damage. This is a major reason patients need to be educated about their pain. Cognitions such as fear, anxiety and faulty beliefs may impact the pain experiences and changing cognitions are important in changing pain behavior. If patients understand that the pain they are experiencing may not be a true indication of the health of their tissues, they may experience less fear of their pain, and may be able …

The Effects Of Chronic Calcium Dysregulation On Behavioral And Pathological Features Of Alzheimer's Disease, Jonathan Sabbagh

UNLV Theses, Dissertations, Professional Papers, and Capstones

Alzheimer's disease (AD) is a progressive neurodegenerative disorder whose etiology is unknown. Recent studies have implicated alterations in calcium homeostasis as a pathogenic contributor to AD. Calcium dysregulation has been observed in aged and AD brains, an event which could potentially facilitate the development of multiple pathologies observed in AD. Specifically, disrupting intracellular calcium levels in vitro has been demonstrated to increase amyloid-beta (Aβ) production, tau phosphorylation, and neuronal loss. However, there is a paucity of data on the behavioral and biochemical consequences of chronic in vivo perturbation of calcium homeostasis. In a series of experiments designed to evaluate the …

Few studies have examined school nurse recognition and attitudes regarding school refusal behavior. The purpose of this study was to assess school nurses' recognition of school refusal behavior, their attitudes regarding the nursing care of children with school refusal behavior, and …

Oxidative Stress For An Acute Bout Of Bikram Yoga In Healthy, Trained Adults, Kimberly Anne Trocio

UNLV Theses, Dissertations, Professional Papers, and Capstones

BACKGROUND:Generation of free radicals resulting in oxidative damage has been linked to cellular damage, aging, and human disease. Many studies have reported that physical exercise can contribute to oxidative stress. Further, exercise in a hyperthermic environment can promote additional oxidative stress. It is important to consider that practices in yoga may be beneficial in reducing oxidative stress according to some studies. The compound effects of exercise and hyperthermic exposure are experienced in the practice of Bikram yoga, the original "hot" yoga. Because Bikram yoga and other hot exercise classes are an increasingly growing fitness trend, it is necessary to investigate …

Sickle Cell Disease: A Quality Improvement Initiative For Emergency Department Providers, Pretrescia Marie Walker

UNLV Theses, Dissertations, Professional Papers, and Capstones

Sickle Cell Disease (SCD) is an incurable, chronic condition that results in a constellation of disorders, frequent emergency department (ED) visits, and repeated hospital admissions. Those affected often suffer from pain crisis, infection, acute chest syndrome, stroke, and multi-organ impairment and frequently do not receive adequate pain management during acute pain episodes because ED providers view them as drug seeking. The majority of patients with SCD are African-American and may be low income, uninsured, or on Medicaid. As a result, these demographics make ED under-treatment of pain in patients with SCD a health equity issue. This was a pre-experimental one …

Evaluating Shared Governance For Nursing Excellence, Evette Michelle Wilson

UNLV Theses, Dissertations, Professional Papers, and Capstones

The national challenges of nursing shortages, decreased staffing levels, and increased patient acuities have contributed to nurse's increased workload and job dissatisfaction. Nurses have become frustrated with the professional practice environment. The inability to make decisions about issues that affect their nursing practice and the care provided to their patients results in nurses leaving the work environment in search of higher job satisfaction. Employers are becoming more creative in their strategies to improve the work environment and retain nurses within their organizations. Healthcare leaders have implemented management strategies such as shared governance models. These models focus on providing a satisfying …

The Presence Of Methicillin Resistant Staphylococcus Aureus (Mrsa) On Environmental Surfaces In Healthcare Facilities Pre- And Post-Cleaning, Aaron Thomas Hunt

UNLV Theses, Dissertations, Professional Papers, and Capstones

The emergence of antibiotic resistant bacteria is a serious public health issue affecting millions of people. Methicillin-resistant Staphylococcus aureus(MRSA) is a leading cause of healthcare acquired infections today. Research has shown that patients infected or colonized with MRSA shed the bacteria into the environment, where the bacteria can survive for long periods of time and become potential sources of infection. Currently, infection prevention efforts focus on active surveillance, hand hygiene, personal protective equipment use and antimicrobial stewardship, with less attention given to environmental cleaning. Nevertheless, environmental cleaning is essential to remove infectious agents from environmental surfaces and prevent transmission. The …
