Perception And Use Of Communication Care Plans By Certified Nursing Assistants In Nursing Homes: The Role Of Professional Support, Christen G. Page

Theses and Dissertations--Rehabilitation Sciences

The majority of individuals in nursing homes have cognitive-communication impairments which impact quality of care because direct care providers, certified nursing assistants, (CNAs) are unsure how to respond to resident’s communication behaviors. One intervention that facilitates staff-resident communication in nursing homes is communication plans; however, the research to date about communication plans has not specifically involved CNAs.

The purpose of this study, using a grounded theory qualitative approach, was to describe development, implementation and evaluation of communication care plans (CCPs) for residents with cognitive-communication impairments in nursing homes by CNAs who did and did not receive professional support. Communication care …

Coffee: A Selected Overview Of Beneficial Or Harmful Effects On The Cardiovascular System?, Thomas F. Whayne Jr.

Internal Medicine Faculty Publications

With a history that began in 800 A.D., coffee is the most popular drink known and as a result, the issues regarding its physiologic effects deserve attention. Maintaining alertness is a well-known benefit and in addition, the cardiovascular (CV) effects of the active compounds, which include polyphenols and caffeine, must be considered. Genetics are relevant and where slow caffeine metabolism is inherent, the risk of nonfatal myocardial (MI) has been shown to be increased. Overall risk for coronary heart disease (CHD) is not supported and unless there is excessive intake, congestive heart failure (CHF) is not adversely affected; in moderation, …

Effective Youth Suicide Prevention: Evidence From Kentucky, Dessi Slavova, Hatim A. Omar

Pediatrics Faculty Publications

In 2013, Suicide was the second leading cause of death among U.S. young adolescents (15-19 years of age), accounting for 18.4% of all deaths in this age group. According to a nationally representative study on the lifetime prevalence of adolescent suicidal behaviors, 12.1% of U.S. adolescents experience suicidal ideation, 4.0% develop a plan, and 4.1% attempt suicide. The same study estimated that approximately 60% of young people with a suicide plan will attempt suicide, and most of the adolescents who subsequently make an attempt do so within the first year after the onset of ideation.

These findings support the importance …

Cross-Talk Between The Tumor Suppressors Par-4 And P53, Tripti Shrestha Bhattarai

Theses and Dissertations--Toxicology and Cancer Biology

This work describes the fascinating interplay between two tumor suppressors Prostate apoptosis response-4 (Par-4) and p53. The guardian of the genome, p53, is frequently mutated in human cancers, and may contribute to therapeutic resistance. However, p53 is intact and functional in normal tissues, and we observed that specific activation of p53 in normal fibroblasts could induce apoptosis selectively in p53-deficient cancer cells. This paracrine apoptotic effect was executed by Par-4 secreted in response to p53 activation. Accordingly, activation of p53 in wild-type mice, but not in p53^-/- or Par-4^-/- mice, caused systemic elevation of Par-4 that induced apoptosis …

Impact Of Kentucky Vaccination Exemption Laws On Pertussis Incidence, Katherine Blain

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

Purpose: According to CDC statistics, prior to pertussis vaccine development in the 1940’s, about 200,000 children contracted pertussis annually. Today, although this number has decreased drastically, pertussis cases began trending upward again in the 1980’s. There are several proposed contributory factors, including vaccination exemption. In Kentucky, there are both medical and religious exemptions to mandatory school vaccines. The purpose of this study was to examine possible correlations between reported school vaccination exemptions and pertussis incidence in Kentucky counties between the years 2004-2012.

Methods: This study retrospectively analyzed data from 120 Kentucky counties between 2004-2012. The Commonwealth of Kentucky School Annual …

The Effect Of Β-Hydroxy-Β-Methylbutyrate (Hmb) Supplementation On Neuromuscular Performance Following Fatiguing Exercise In Healthy Subjects, Jordon W. Macht

Theses and Dissertations--Kinesiology and Health Promotion

Supporters of a nutritional supplement, β-Hydroxy-β-Methylbutyrate (HMB) supplementation, claim that it will increase the muscular strength gains and lean muscle mass gains seen during a resistance training program. It has been suggested that HMB supplementation does this by preventing muscle damage or by regenerating damaged muscle cell membranes. However, no research has evaluated the effect of HMB supplementation on low frequency fatigue. Therefore, the purpose of this study was to determine if three weeks of HMB supplementation could attenuate the effects of low frequency fatigue caused by eccentric muscle contractions of the tibialis anterior muscle. A total of 33 healthy …

The Effects Of Spinal Manipulative Therapy On Isokinetic Strength And Postactivation Potentiation, Grant D. Sanders

Spinal manipulative therapy (SMT) is a therapeutic procedure employed by various healthcare practitioners for alleviating acute and chronic musculoskeletal complaints. This form of treatment is also delivered to enhance the performance and augment the rehabilitation of athletes. However, despite research findings alleging the strength-modulating effects of SMT alongside numerous professional athletes’ positive anecdotal claims concerning its results, the physiological processes to explain its effects remain largely unexplained. Therefore, the purpose of this work was to investigate the effects of SMT in a college-aged sample population with two experiments.

The first study examined the effect of SMT targeting the lumbosacral region …

Parent Involvement And Science Achievement During Students’ Transition Years From Elementary School To Middle School: A Cross-Lagged Panel Analysis Using Ecls-K, Letao Sun

Theses and Dissertations--Educational Policy Studies and Evaluation

Transitioning from elementary school to middle school can be a difficult time for many adolescents. It is a period often correlated with a decline in students’ academic achievement, perceptions of performance, potential, and value in schooling. Research has shown evidence that parents’ involvement in their children’s education significantly influences children’s academic achievement. However, there are many conflicting findings regarding this relationship.

The primary purpose of this study is to extend existing research on academic achievement by examining the causal relationship between parent involvement and science achievement during the transition years, using data from the Early Childhood Longitudinal Study, Kindergarten Class …

The Effect Of Cholesterol On The Osteoblast Responsiveness To Hydrodynamic Pressure Stimulation, Kristen Lough

Theses and Dissertations--Biomedical Engineering

Hypercholesterolemia is a risk factor for osteoporosis but the underlying mechanism is unknown. Previous evidence suggests that osteoporosis results from an impaired regulation of osteoblasts by fluid pressure fluctuations in the bone matrix. Recently, our laboratory showed that enhanced cholesterol in the cell membrane, due to hypercholesterolemia, alters leukocyte mechanosensitivity. We predict a similar link between osteoblasts and hypercholesterolemia leading to osteoporosis. Specifically, we hypothesize that extracellular cholesterol modifies the osteoblast sensitivity to pressure. MC3T3-E1 cells were exposed to hydrodynamic pressures regimes (mean=40mmHg, amplitude=0-20mmHg, frequency=1Hz) for 1-12 hours. To assess the impact of membrane cholesterol enrichment, cells were pre-treated with …

Critical-Reflective Thinking: A Phenomenology, Margot D. Wielgus

Theses and Dissertations--Philosophy

This dissertation formulates and describes a type of thinking called critical-reflective thinking. Examples of critical-reflective thinking appear in the works of many major Western philosophical figures, including the main thinkers considered here, Plato, Martin Heidegger, Hannah Arendt, and Henry David Thoreau. Although this list of thinkers is eclectic, these philosophers come together in describing a common phenomenon, although they do not thematically designate or explain it. Their works illustrate a type of thinking in which people are invited by prompting events to consider their presuppositions—notions they have taken as true without prior consideration. I have deemed this phenomenon “critical-reflective thinking” …

Insights Into Perspectives On Environmental Sustainability, Amber R. Shobe

Theses and Dissertations--Community & Leadership Development

As scientists become more aware of the imposing threats associated with climate change, university leaders are encouraged to become familiar with the principles of sustainability. Abundant research already supports the relevance of environmental sustainability in higher education; however, there exists a gap in the literature which investigates an understanding of environmental sustainability and the implementation of its practices. By examining colleges at the University of Kentucky, this study identifies organizational barriers to recognizing a thorough understanding of environmental sustainability at the departmental level. The results indicate that out of the eight colleges selected, two have no existing environmental sustainability programs …
