Self-Care Practices In Doctoral Nursing Students And Effects On Educational Experience, Megan Lutman

Dissertations

Problem: Doctoral nursing students are often faced with stressors on top of their schooling, one of which is continuing to work while pursuing their education. This in combination with normal life stressors can be challenging. The purpose of this project was to survey doctoral nursing students on what their current self-care practices.

Methods: An exploratory needs assessment project was created to gather data from Doctor of Nursing practice (DNP) and Doctor of Philosophy (PhD) nursing students in an urban, mid-sized, Midwestern, public university to identify current self-care practices, barriers to self-care, preference of self-care practices, and the impact these …

Acute Agitation Intervention Tool For Reduction Of Polypharmacy, Brooks J. Propst

Dissertations

Introduction: Patients with behavioral health diagnoses are among the highest risk for
aggression. For pediatric patients with behavioral health needs, urgent treatment is
needed for aggressive behavior, due to the potential unwanted outcomes. The purpose of this Quality Improvement (QI) pilot project was to implement an Acute Agitation Intervention Tool that uses the Broset Violence Checklist (BVC) to guide
pharmacological intervention for mild and moderate to severe agitation in pediatric
patients with behavioral health needs ages 8 to 18 to decrease the number of medications that patients are getting per agitation event over a 12-week period.

Methods: This QI included …

Hiv And Early Life Stress On Neuroimaging And Risky Behavior, Paola Garcia Egan

Dissertations

This study examined the interactive effects of early life stress (ELS) and HIV on brain morphometry, diffusion-basis-spectrum-imaging (DBSI), risky decision-making, and sex-risk behavior. 122 people with HIV (PWH) and 113 people without HIV (PWoH), free of major psychiatric illness and neurological confounds, were stratified into high (≥ 3 events) vs. low (< 3 events) ELS [PWoH/low ELS (n = 57), PWoH/high ELS (n =56), PWH/low ELS (n = 43), PWH/high ELS (n = 79)] and underwent structural magnetic resonance imaging, DBSI, neuropsychological, and risky-behavior assessment; all PWH were virologically controlled. Compared to PWoH, PWH had smaller orbitofrontal cortex (OFC), parietal lobes, insula, caudate and anterior cingulate. No ELS effects were detected in volumetric measures. Significant interactions were found between HIV serostatus and ELS on the OFC and on cellularity of the inferior fronto-occipital fasciculus after multiple comparisons adjustment. Specifically, PWH/high ELS exhibited significantly smaller OFC and PWoH/high ELS show significantly larger OFC than the other groups. PWoH/high ELS exhibited higher DBSI cellularity (neuroinflammation proxy) of the inferior-occipital-fasciculus compared to PWoH/high ELS. Regardless of HIV status, executive function moderated the relationship between the OFC and sex-risk behavior such that individuals within the sample who performed above average on a measure of executive function and had a larger OFC reported fewer sex partners in past six months than individuals with smaller volumes. No interaction was found between HIV serostatus and ELS on risky behavior measures. Clustering analyses defined ELS subgroups in PWH that were determined by demographic characteristics, duration of infection, recent CD4+ T-cell count, nadir CD4+ T-cell count and high/low ELS.Even in PWH that are virologically controlled, without major current psychiatric comorbidities, there is evidence of a synergistic impact of ELS and HIV on OFC volumes. Higher volumes in the OFC were detrimental when associated with lower executive function scores or advantageous when associated with higher executive function. Findings suggest that ELS is associated with different brain signatures among PWoH and virally suppressed PWH. However, ELS was not directly associated with risky behaviors, and subgroups in PWH were characterized by demographic variables, past substance use and HIV clinical variables.

Evaluating Sbirt In A Behavioral Health Urgent Care, Christina L. Williams

Dissertations

Background: Adolescent substance use (SU) is a major health concern. Most youth who engage in alcohol and other SU do not meet criteria for SU disorder (SUD). Nonetheless, evidence shows SU during adolescence impacts cognitive, social, and emotional development, increases risk of physical injury, and may progress to SUD in adulthood. Only half of clinicians properly screen adolescents for SU; those identified with SUD often receive no intervention. Screening, Brief Intervention, and Referral to Treatment (SBIRT) is an evidence-based intervention to address this problem. The purpose of this project was to evaluate implementation of SBIRT using CRAFFT 2.1+N, a SU …

Empowering Nurses Of Minority In The Face Of Incivility And Bullying: Through The Lens Of Phenomenology, Corrine Floyd

Dissertations

Abstract

Up to 85% of nurses have reported exposure to incivility in the workplace (Hunt & Marini, 2012). The often-subtle nature of incivility toward nurses in a minority population may partially explain why it remains a problem. Healthcare organizations realize the need for civility to counter the high turnover rate, staff shortages, and low job satisfaction reported by nurses, but lack understanding of how nurses of a minority population perceive incivility and bullying. This study aimed to answer the research question how do nurses with minority representation experience incivility and bullying versus empowerment in the workplace? A descriptive phenomenological design …

The Influence Of Stressful Life Events On The Development Of Type 2 Diabetes, Joshua Minks

Dissertations

This study examined the relationship between distress and the development of Type 2 diabetes mellitus (T2DM) in the presence of established risk factors. Distress secondary to mental health disparities, stressful life events, and work conditions has been shown to promote insulin resistance and the development of T2DM.

Subjects (N=79) diagnosed with T2DM within the previous six months were recruited from SSM Health Centers and VA Medical Centers in the greater St. Louis area. They completed the Recent Life Changes Questionnaire, ENRICHD Social Support Instrument, and a demographic survey and analyses were conducted to determine differences between the veteran …

Right Hemisphere Capacities For Word-Finding: Bilateral Modulation Of Event-Related Potentials In Healthy Adults And Adults With Aphasia, Amanda C. Alton

Dissertations

Language tasks are typically lateralized to the language dominant left hemisphere in healthy right-handed adults. Additionally, lesions in left frontotemporal areas typically result in a variety of language impairments called aphasia. Interestingly, increased activation in right cerebral regions homologous to left side lesions has been observed in patients with aphasia during word-finding tasks. The neural mechanism and the impact on word-finding remain unclear. There are two competing theories concerning compensatory right hemisphere activation. One view is that the right hemisphere plays a supportive role, taking over functions of the damaged left hemisphere. The other perspective is that rightward laterality is …
