Exploring The Influence Of Contextual Factors And The Caregiving Process On Burden, Quality Of Life, And Outcomes Of Heart Failure (Hf) Dyads After A Hospital Discharge Guided By The Individual And Family Self-Management Theory (Ifsmt): A Mixed Method Study, Tamara Bernard

Theses & Dissertations

ABSTRACT The purpose of this study is to explore the influence of contextual factors and caregiving process characteristics on proximal outcomes of the patient and caregiver after discharge from the hospital. The long-term goal of this research is to reduce caregiver burden and improve patient outcomes. Heart failure (HF) is an increasingly common chronic illness with unique caregiving needs and a high rate of hospital readmissions. Caregiver burden has been researched extensively in other areas of medicine such as oncology and dementia and has been reported for stable chronic HF patients in an outpatient setting. However, there is little research …

Frailty Determination And Responsiveness In Left Ventricular Assist Devices, Sarah Schroeder

Theses & Dissertations

Frailty, the state of being vulnerable with susceptibility to decreased age-related physical reserve, is found in 56-79% of adults with end-stage HF receiving durable left ventricular assist device (dLVAD) therapy. Frailty increases risk of adverse events, including increased mortality in the dLVAD population, but less is known about depression, quality of life (QOL), cognition and frailty responsiveness. Therefore, we aimed to describe and compare frailty (5-Meter Walk Test, 5MWT), depression (Patient Health Questionnaire-9, PHQ-9), quality of life (EQ5D Visual Analog Scale, EQ-5D VAS) and cognition (Trailmaking B) from pre- to 12-months post-dLVAD We also compared demographics, clinical characteristics, and post-dLVAD …

Ethical Sensitivity Of Padis Care Among Critical Care Nurses: A Mixed Methods Study, Denise Waterfield

Theses & Dissertations

Critically ill patients often experience distressful and impactful symptoms and conditions that include pain, agitation/sedation, delirium, immobility, and sleep disruption (PADIS). The presence of PADIS can affect recovery and long-term patient outcomes. An integral part of critical care nursing is PADIS prevention, assessment, and management. To better understand the complexities of PADIS care, two reviews of the literature were completed. The first is an integrative review of the use of PADIS assessment tools by critical care nurses. The second is a qualitative systematic review of the literature on the integration of care ethics and nursing workload. Ethical sensitivity of everyday …

Theses & Dissertations

African American (AA) women continue to have the lowest rates of breastfeeding. This continues to create a health disparity even though breastfeeding is extensively recognized in the scientific and health care communities as the optimal feeding choice for infants. This study examined the relationship between the external variables (social support network and community resources) and the explanatory variables (attitudes, norms, and perceived self-efficacy) and intention to breastfeed, for the AA, first time, low-income, emerging adult pregnant woman. The Integrated Behavior Model (IBM) was used as the theoretical framework to guide this study in better understanding the variables influencing breastfeeding intention. …

Factors Associated With Omani’S Schoolteachers’ Reporting Behavior Of Suspected Cases Of Child Abuse And Neglect, Zeinab N. Alazri

Theses & Dissertations

Child abuse and neglect is a global problem that can result in severe negative consequences for victims and their societies. Numerous initiatives have been launched by the United Nations Children's Fund (UNICEF) to combat this problem. Recently, Sultanate Oman, an Arab country, has mandated schoolteachers to report suspected abuse and neglect cases to comply with UNICEF's recommendations. As schoolteachers spend a great deal of their time with children, they are in a good position to recognize and report suspected abuse and neglect cases so the victims can get the needed help and treatment. There is a dearth of information about …

Examining access and utilization of healthcare services using a consumer framework incorporating both access barriers and facilitators and consumer-level dimensions that affect choice in seeking care may inform access and utilization research. The purposes of this dissertation were 1) to explore the presence of facilitators and barriers to care in ambulatory healthcare locations for non-emergent care …

Glycemic Variability In Patients With Stage Ii-Iii Colon Cancer, Natalie Mandolfo

Theses & Dissertations

Patients with cancer experience metabolic changes such as hypoglycemia, hyperglycemia, and glycemic variability; collectively termed malglycemia. Glycemic variability, defined as fluctuations in glucose, is a marker of metabolic instability. Higher glycemic variability is associated with adverse health outcomes in the general population and in those with diabetes. Little is known about glycemic variability in patients with cancer, especially those with solid tumor malignancies. Glycemic variability is associated with increased infection, shorter periods of remission, and higher mortality in patients with hematological cancer. This body of work describes the concept and measurement of glycemic variability to assess glycemic control in patients …

The Role Of Extracellular Vesicles In Cancer-Related Fatigue And Its Co-Occurring Symptoms, Dilorom M. Sass

Theses & Dissertations

Cancer survivors report many debilitating symptoms associated with cancer and its treatments. About 30% will report long-term cancer-related fatigue (CRF) which often co-occurs with depressive symptoms, sleep disturbances, cognitive fatigue, and poor overall health-related quality of life. The underlying causes of these co-occurring symptoms have been related to systemic processes such as inflammation. Extracellular vesicles (EVs) contain systemic markers such as genetic and protein materials that inform about cell-to-cell interactions that influence immune signaling and inflammatory processing. No study to date has explored the associations of EVs with cancer-related symptoms. So, the purpose of this dissertation was to investigate the …

Self-Management For Individuals Using Long-Term Urinary Catheterization, Lisa Krabbenhoft

Theses & Dissertations

Many individuals with adult neurogenic lower urinary tract disorder require long-term urinary catheterization for bladder management. The daily use of urinary catheterization increases the risk for chronic complications including catheter associated urinary tract infections. Previous studies have used self-management interventions to reduce chronic complications in the community setting. However, there are limited intervention studies focused on reducing chronic complications after discharge from a rehabilitation hospital. The purpose of this dissertation study is to examine the feasibility and impact of a self-management intervention on individuals after leaving rehabilitation hospital for home within the community.

This dissertation comprises two studies, the first …

Examining Depressive Symptoms Over Time In Women With Coronary Heart Disease, Sydney A. Buckland

Theses & Dissertations

Coronary heart disease (CHD) is the number one killer of women in the US. Women also experience roughly twice as much depression as men, and depression in CHD is associated with increased morbidity and mortality. Despite these facts, women continue to be under-represented in CHD research, and results by gender are not routinely reported.

Screening for depression in this population is problematic due to inconsistent inclusion of somatic symptoms on screening instruments and disagreement about appropriate cutoff scores.

This body of work clarifies the concept of depression in women with CHD, presents a systematic review of the longitudinal literature on …

Maternal Life Course Adversity: The Intersection Of Psychosocial And Biobehavioral Adaptive Response In Pregnancy, Crystal Modde Epstein

Theses & Dissertations

The link between life course adversity and adverse health outcomes is well established, particularly early life adversity (ELA). There is also evidence that the physiologic adaptations associated with stress, depression and ELA can be transmitted intergenerationally via long-term set-point changes within the maternal hypothalamic-pituitary-adrenal axis (HPA). It is unknown how the type and timing of maternal stress and adversity influences HPA regulation during pregnancy and whether maternal coping attenuates this relationship. Manuscript 1 was an integrative review of studies examining the association between maternal ELA and HPA regulation during pregnancy. In manuscripts 2 and 3 the findings of the dissertation …

Self-Efficacy For Symptom Management In Adult Hematopoietic Stem Cell Transplant Patients, Lynn White

Theses & Dissertations

Hematopoietic stem cell transplant (HSCT) is a treatment for hematologic cancers and other hematologic conditions that causes severe treatment-related symptoms. The first 30 days after HSCT, or the acute phase, is when symptoms are most intense. During this time, the ability of patients to manage their symptoms, in collaboration with their health care providers, is crucial to reduce the distress caused by the symptoms. Self-efficacy is the person’s confidence in their ability to perform a behavior, such as symptom management. This body of work describes the concept of self-efficacy for symptom management (SESM), presents an integrated literature review on self-efficacy …

Peer Intervention To Increase Physical Activity Among Working Women, Sheri A. Rowland

Theses & Dissertations

Most Americans do not engage in enough healthy physical activity (PA), with working women particularly at-risk for inactivity. Workplace PA interventions have been effective, however studies using peers as the central theoretical strategy, have not been found. Social cognitive theory and social comparison theory were used to develop a peer-modeling workplace PA intervention. The aims of this experimental, two-group, preliminary study were: 1) assess intervention feasibility, 2) determine the intervention effect on cardiorespiratory fitness (primary outcome), and PA behavior, cardiovascular risk, self-efficacy, motivation, and social comparison, and 3) describe participant perceptions of the intervention using qualitative focus-group data.

Genetic Influence On Resilience To Potentially Traumatic Events, Kosuke Niitsu

Theses & Dissertations

Most individuals experience at least one potentially traumatic event (PTE), such as a natural disaster. When exposed to PTEs, some individuals are more vulnerable to develop psychopathology, such as Post-Traumatic Stress Disorder (PTSD). In contrast, others are less adversely affected by PTEs, who are often described as “resilient”. A concept analysis of resilience (Manuscript #1) revealed: the antecedent is PTE; the defining attributes are ego-resiliency, emotion regulation, heredity, and social support; and the consequences are none to mild psychopathological symptoms and positive adaptation. Based on a systematic review of genetic influence on resilience (Manuscript #2), the following 10 polymorphisms were …

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), …

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.

Objective: Examine the relationship between SES and body mass index (BMI) among people with schizophrenia and bipolar disorder.

Design: A secondary analysis of the Collaborative Psychiatric Epidemiology Surveys dataset. The psychiatric group (N=480) included individuals with symptoms of schizophrenia or bipolar disorder. Those reporting no symptoms were controls (N=5,161). Childhood SES variables included mother and father education and profession, …

Psychiatric Comorbidities And Bmi: An Exploratory Analysis, Nicholas Guenzel

Theses & Dissertations

Background: Individuals with most forms of mental illness have higher rates of obesity than members of the general public putting them at an increased risk for many physical health problems that reduce both quality of life and life expectancy. The presence of multiple comorbid psychiatric disorders has been associated with poorer clinical outcomes in other mental health measures such as disability and sobriety and is proposed as a risk factor for elevated BMI (body mass index) in this study.

Objective: Determine if multiple psychiatric comorbidities are associated with elevated BMI and, if so, which combinations are linked with the greatest …
