Essential Competencies For Occupational Therapy In End-Of-Life Care, Karmella Bognot

UNLV Theses, Dissertations, Professional Papers, and Capstones

Occupational therapists carry an abundance of expertise in helping patients and caregivers navigate the end-of-life journey. The lack of knowledge of OT’s role impacts occupational therapy utilization and service provision in hospice. It reduces opportunities for this population to increase their understanding on how to maintain quality-of-life. The more a patient is able to do lessens the burdens shouldered by the caregiver. Education on pain management and promoting comfort are typical priorities addressed; however, not enough training is focused on maximizing independence or engagement in occupations. Competencies encompass a unique set of skills, knowledge, and abilities necessary for successful performance …

Implementation Of A Protocol In The Freestanding Emergency Department To Screen For And Identify Possible Victims Of Human Trafficking, Joe Alvarado

UNLV Theses, Dissertations, Professional Papers, and Capstones

Human trafficking (HT) victims often seek medical care in the emergency room setting. In a recent study among HT survivors, 88% attested to receiving medical care while in captivity, with 63% treated in the emergency care setting. Freestanding emergency departments typically have lower acuity and lower patient volumes than hospital-based emergency departments. This setting creates shorter wait times and minimizes the length of stay at every point during the emergency room experience. For traffickers, this is an ideal situation if their victim needs medical attention, and they want to get in and get out of the emergency room with less …

Mapping Nevada's Dental Workforce, Kelvin Chen

UNLV Theses, Dissertations, Professional Papers, and Capstones

Access to care is a concern at the forefront of public health. Due to socioeconomic and geopolitical pressures, the distribution of healthcare providers across a population often does not coincide with the demand for healthcare in a specific geographic area. Rural areas typically do not have enough providers and urban areas typically have too many. This stark reality underscores an inherent inefficiency in the allocation of healthcare resources and is a discrepancy that must be addressed by state-sponsored institutions and programs. From a public health perspective, the problem of insufficient or lack of access to care is the greater of …

The Influence Of Resistance Training On Post Surgical Outcomes In Individuals With Anterior Cruciate Ligament Injury, Kevin H. Choe

UNLV Theses, Dissertations, Professional Papers, and Capstones

The anterior cruciate ligament (ACL) is commonly injured, especially in individuals under the age of 25. ACL reconstruction (ACLR) is the most common treatment after ACL injury, followed by physical therapy. However, successful surgery and completion of rehabilitation, individuals still demonstrate quadriceps weakness and asymmetries during locomotion. To improve these deficits, an intervention that improves quadriceps strength and lower extremity biomechanics during locomotion is required. First, we aimed to complete a systematic review of the literature to determine the efficacy of resistance training in improving outcomes after ACLR.

The Role Of Nutrition And Hormone Signaling In Extended Larval Development And Obesity In Starvation-Selected Drosophila Melanogaster, Jennifer M. Clark

UNLV Theses, Dissertations, Professional Papers, and Capstones

Brief periods of starvation are a common stressor that most animals encounter in the wild and must be able to survive in order to maximize their fitness. Starvation resistance of the adult fruit fly, Drosophila melanogaster, is thought to be primarily conferred by adult fat stores, body size, metabolic rate, behavior, and activity levels. Additionally, flies selected for starvation resistance also often show delayed pupariation, which is usually indicative of altered hormone signaling. How starvation selection extends development and if it contributes to adult starvation resistance remains incompletely studied. Identifying the targets of starvation selection that cause extended development and …

Petrogenesis Of Hawaiian Lavas: Investigations Using Radiogenic And Non-Traditional Stable Isotopes, Christopher Defelice

UNLV Theses, Dissertations, Professional Papers, and Capstones

Earth’s mantle is the most voluminous part of the planet and is inaccessible to direct investigations. It is only possible to study it through indirect methods, such as the chemical makeup of erupted lavas. The Hawaiian Islands are thought to be the product of the mantle plume hypothesis, sometimes called a hot spot. Material from the Earth’s mantle is brought to the surface and erupted as magnesium rich lavas and form basalts. Hawaii is the longest lived active hot spot on Earth and makes it an ideal candidate for understanding the evolution of the Earth’s mantle and how lavas cool …
