Clinical Study Of Canine Tear Lacritin As A Treatment For Dry Eye, Katherine E. Kelly

Senior Honors Projects, 2010-2019

Keratoconjunctivitis sicca (KCS), the deficiency of tears also known as dry eye, is a prevalent disease that affects both humans and canines. The current treatment for dye eye, cyclosporine (Restatis®), only provides temporary relief, is often associated with discomfort and is inconsistently effective. Lacritin is a naturally occurring tear glycoprotein secreted from the human and canine lacrimal glands. It has been shown that lacritin stimulates basal tearing in rabbits when applied topically. This study characterized the amount and form of lacritin found in the tears of dogs with healthy and dry eyes—information which may be applied to the development of …

Adolescent Grief: The Nurse's Role In Promoting Healthy Coping Mechanisms And Preventing Future Hospitalizations, Erica C. Reighard

Senior Honors Projects, 2010-2019

Age and developmental stage directly influence the grieving individual's ability to understand and process death. Adolescents are especially vulnerable to developing negative coping skills such as substance abuse, self-destructive behaviors, and eating disorders. After a loss occurs, nurses can use their role as a caregiver who is neither a parent nor a peer to provide adolescents with an opportunity to express their grief. Nurses can educate grieving adolescents on the differences between positive and negative coping skills and can therefore reduce the number of future hospitalizations related to ineffective coping mechanisms.

Establishment Of Comprehensive Training Center In Tajikistan, Umeda Sadykova

Theses & Dissertations

There is a notable increase in the number of natural and manmade disasters all over the world in the past two decades. Emergency preparedness is a field that is drawing increased attention in many countries. Tajikistan is a disaster prone country with unforgiving nature and weak preparedness infrastructure/system. Tajikistan’s weak emergency preparedness system can be attributed to two main reasons; lack of coordination between the government and international emergency organizations, and the paucity of well trained and organized network of emergency professionals. This study drafted a proposal to establish a comprehensive training center in Tajikistan. This training center will be …

Mechanisms Of Lateral-Inhibitory Feedback From Horizontal Cells To Cone Photoreceptors At The First Synapse Of The Retina, Ted J. Warren

Theses & Dissertations

Polarization of the horizontal cell (HC) membrane potential causes changes in the synaptic cleft pH that result in inhibitory feedback from HCs to cone photoreceptors (PRs). HCs average signals from many PRs and so negative feedback onto PR terminals from HCs subtracts the average luminance of the visual scene from the light responses of an individual cone. This feedback operates by changing the voltage-dependence and amplitude of the L-type Ca²⁺ current (I_Ca) that regulates synaptic release. Feedback regulation of PR Ca²⁺ channels involves protons but the mechanism by which this pH change occurs is unclear. We …

Mobility Of Individuals With Multiple Sclerosis And The Influence Of Physical Therapy, Brenda L. Davies

Theses & Dissertations

One main purpose was to explore the compensatory gait strategies of individuals with multiple sclerosis (MS). To address this purpose, we quantified the mechanical work generated by the lower extremity joints during walking. The outcomes from this investi­gation suggested that individuals with MS redistribute positive mechanical work during walking to the hip in order to compensate for a reduced ability of the ankle to generate positive mechanical work. Additionally, we also explored the motor control of the ankle as a potential contributing factor to the mobility limitations of individuals with MS. The outcomes from this investigation indicated that individuals with …

Effects Of Prenatal Gestational Diabetes Nutrition Education Class And Individual Follow-Up On Maternal And Infant Outcomes, Samantha List

Fifty-four individuals with CHF participated in a 7 day session to estimate their daily physical activity by using the RT3 accelerometer and 7-day PAR questionnaire. In addition, 15 of the 54 individuals participated in a second study in with …

Expression And Function Of Inflammation-Associated Micrornas In Traumatic Brain Injury, Emily Harrison

Theses & Dissertations

MicroRNAs (miRNAs) are important regulators of gene expression. Many neurological diseases, including traumatic brain injury alter expression of miRNAs in the brain. However, the function of these molecules in the context of TBI is largely unknown. Here we report multiple potential roles for miRNAs in TBI, some of which extend beyond the traditional model of post-transcriptional regulation, highlighting that these RNA molecules may have broader implications for the neurobiology of disease. We found that miR-155 plays an essential role in interferon expression after CCI and that miR-155 contributes to TBI induced anxiety, potentially through regulation of interferons. Expression of miR-155 …

Modifiable Barriers To Optimal Outcomes In Gout Management, Brian W. Coburn

Theses & Dissertations

Improving patient outcomes in chronic disease is of critical importance to the future of health care. Gout, affecting 4% of the US population, is a highly treatable chronic disease from which patients experience unnecessarily suboptimal outcomes. In this dissertation, I demonstrate how interrelated patient and provider factors affect patient outcomes in gout. First, I describe how only 14% of gout patients know their serum urate (SU) goal for urate lowering therapy (ULT) despite otherwise being knowledgeable about gout and its treatment. I then demonstrate the importance of multiple patient and provider factors in achieving SU goal. Specifically, I demonstrate that …

Proportion Of Heart Failure Patients Who Meet Criteria For Malnutrition Upon Hospital Admission Based On Aspen Guidelines, Sarah L. Johnson

Theses & Dissertations

Background: Current research estimates that approximately 50 percent of heart failure patients are categorized as malnourished. Heart failure patients are at increased risk of malnourishment due to increased catabolic processes that increase resting energy expenditure, decrease appetite, impair nutrient absorption, and lead to unintentional weight loss. The goal of standardized diagnostic criteria is to identify malnutrition early for more effective treatment. Current studies suggest the association of early diagnosis and nutrition intervention with increased positive patient outcomes and improved quality of life for heart failure (HF) patients. However, the proportion of patients with HF who meet criteria for malnutrition at …

Rural Nebraska Women's Explanatory Models Of Postpartum Depressive Symptomatology, Elizabeth Mollard

Theses & Dissertations

The purpose of this study was to construct the explanatory models of postpartum depressive symptomatology (PPDS) from the perspective of rural Nebraska women and to compare these models with the medical model of PPDS. A sample of 20 rural Nebraska women were interviewed in a one-on-one qualitative descriptive telephone interview using questions based on Kleinman’s (1980) explanatory model of illness. This study used feminist pragmatism as a guiding philosophical paradigm.

Factors And Outcomes Associated With Potentially Inappropriate Medication Use In Rural Community-Dwelling Older Adults, Marcia Y. Shade

Theses & Dissertations

Potentially inappropriate medications (PIMs) use in older adults is a significant public health concern. The use of PIMs to avoid may lead to negative outcomes such as adverse drug events. Prior conceptual analysis of PIMs use and observation of health-related factors in rural adults led to the design of this dissertation study. A sample was recruited from a population of rural community-dwelling older adults to examine the following specific aims: 1) Describe the use of PIMs to avoid, 2) Explore individual demographic characteristics (age, gender, income, education, and rural home location), health experience (comorbidity, number of medications and health providers), …

The Role Of Cbl Family Of E3 Ubiquitin Ligases In Intestinal Epithelial Homeostasis, Neha Zutshi

Theses & Dissertations

All adult organs are endowed with a small pool of resident stem cells that must be maintained throughout life to provide for cell turnover during homeostasis and tissue repair following any injury. The unique ability to self-renew as well as to differentiate into functional cells of organs in which they reside makes stem cells essential for the maintenance of organ systems. It is now becoming increasingly evident that aberrant activity of stem cells contributes to diseases such as cancer or tissue/organ atrophy. Thus, it is critical to better understand the mechanisms that regulate adult stem cells. Ligand-activated receptor tyrosine kinases …
