UNLV Theses, Dissertations, Professional Papers, and Capstones

One of the world’s most serious health issues today is the increasing prevalence of diabetes (Chobev, Sotirovska, Mihajilov, 2011). Indeed, the growth of this widespread and pernicious disease has been categorized as epidemic. The antidote for the diabetes epidemic lies in prevention and the use of a chronic care model that focuses on improving diabetes self-management. For both diabetes prevention and self-management, a core component pertains to knowledge—and specifically to improved public health literacy, public health education, and patient education. For example, ongoing patient education is a critical factor in helping patients to manage their diabetes and prevent the micro- …

The Presence Of Clostridium Difficile On Environmental Surfaces In Healthcare Facilities Pre- And Post-Decontamination Of Patient Rooms, Theresa Trice

UNLV Theses, Dissertations, Professional Papers, and Capstones

Healthcare-associated infections (HAIs) are infections related to receiving medical care. HAIs are responsible for an excess of morbidity and mortality among hospitalized patients. Though most HAIs rates are on the decline, Clostridium difficile infection rates are at an all-time high, primarily due to the persistence of C. difficile spores in the environment. In the United States, Clostridium difficile-related mortality rates per million have increased from 5.7 in 1999 to 23.7 in 2004, with an estimated 26,642 deaths due to Clostridium difficile infections (CDIs). Clostridium difficile is transmitted via the fecal-oral route or aerosolized endospores, but it can also be transmitted …

The Effect Of Sleep On Perceptual Learning And Memory Consolidation, Vanessa Claire Irsik

UNLV Theses, Dissertations, Professional Papers, and Capstones

An ability to segregate speech accurately is essential given that most auditory environments contain other overlapping conversations or environmental noise. While perceiving speech among background noise can be difficult in and of itself, those with hearing impairments can experience considerable difficulty. While training has been shown to benefit perceptual segregation of trained sounds, it is unclear how such training transfers to sounds not included in a training regimen. The current study aimed to address this question by training listeners on a portion of sounds during a vowel segregation task, and subsequently testing on both the trained sounds and untrained sounds. …

Four Weeks Of Minimalist Style Running Training Reduced Lumbar Paraspinal Muscle Activation During Shod Running, Stephanie Barton, David Brown, Talia Joyce

UNLV Theses, Dissertations, Professional Papers, and Capstones

Background and Purpose: Research has shown that the risk of low back dysfunctions in runners is related to the increased mileage of distance running. Repetitive shock loading of the spinal structures during running has been indicated as one of the important biomechanical mechanisms underlying such injury. Acute changes in foot strike pattern, like those seen during minimalist style running, have been shown to lead to modifications in lumbar range of motion. Minimalist style running could lead to changes in lumbar biomechanics and muscle activation, potentially reducing the loading on the musculoskeletal structures of the lower back. However, the long term …

Increasing Comfort With End-Of-Life Discussions, Theresa Catherine Berton May 2015

Increasing Comfort With End-Of-Life Discussions, Theresa Catherine Berton

UNLV Theses, Dissertations, Professional Papers, and Capstones

End-of-life discussions and advanced care planning are part of the healthcare process, and within the scope of practice for providers. Despite the evidence supporting the effectiveness of these conversations, the system falls short. Talking about death is never easy. At times, it is difficult for healthcare providers to approach the topic with patients who are living with serious life-limiting illness. Reports in the end-of-life literature reveal that healthcare professionals avoid discussions about preparations for end-of-life care due to feeling unprepared, and a lack of framework for such discussions. Purpose: The purpose of this doctoral project was to improve the quality …

Lead Hazard Control In Henderson, Nevada: Identifying Critical Areas And The Associated Costs, Khaye Gerazel Arcilla Rufin

UNLV Theses, Dissertations, Professional Papers, and Capstones

Lead poisoning is a common, yet preventable childhood health problem in the United States today. Studies show statistically significant (p < .05) associations between higher childhood lead exposure and subsequent negative developmental outcomes. Since 1993, the U.S. Department of Housing and Urban Development (HUD) Lead Hazard Control (LHC) Grant Program has devoted more than $1 billion in funding to several cities.

This study investigated a total of n=75 homes enrolled into the Henderson Lead Hazard Control and Healthy Homes Program (HLHCHHP) from December 2013 – February 2015. A logistic regression was performed to ascertain the frequency of lead-based paint (LBP) found in homes based on the year it was constructed. Of the 75 enrolled and tested for LBP, 58 homes (77.3%) were found to contain LBP and 17 homes (22.7%) did not contain LBP. The significance value of p=0.013 shows that …

Functional Capacity In Schizophrenia: Relationship Among Effort, Reinforcement Learning And Self-Beliefs, Sally J. Vogel May 2015

Functional Capacity In Schizophrenia: Relationship Among Effort, Reinforcement Learning And Self-Beliefs, Sally J. Vogel

UNLV Theses, Dissertations, Professional Papers, and Capstones

Individuals with schizophrenia exhibit a wide range of complex neurocognitive, psychiatric and behavioral impairments. Recent research suggests that this complex array of symptoms can be at least partially accounted for by dysfunction in more basic mechanisms, such as the ability to learn from positive and negative reinforcement, or the ability to exert adequate effort when completing simple tasks. Evidence also suggests that deficits in these basic mechanisms may contribute to more complex symptoms, such as functional impairment. Also, the relationship between neurocognitive deficits and functional impairment has been found to be mediated by defeatist performance beliefs. However, studies have not …
