Maintaining Nurses' Currency In Informatics, Jennifer Alaine Strawn

UNLV Theses, Dissertations, Professional Papers, and Capstones

Technology has changed how registered nurses (RNs) provide care at the bedside. As more technologies are utilized to improve quality of care, safety of care, maximize efficiencies, and decrease costs of care, one must question how well the information technologies (IT) are fully integrated and utilized by the front-line bedside nurse in his or her practice. Despite the pervasiveness of IT in healthcare, there is a paucity of literature on how Chief Nursing Officers (CNOs) assure the ongoing education and training for nurses to maintain IT competencies in the practice environment.

From this author’s lived experience as a CNO, it …

Psychometric Testing Of The Malaria Critical Thinking Test, Tally Rae Tinjum

UNLV Theses, Dissertations, Professional Papers, and Capstones

Accrediting bodies of baccalaureate nursing programs require quantified assessment of critical thinking in students. The current literature indicates two types of critical thinking assessments: (a) standardized, psychometrically sound, and non-nursing specific, and (b) nursing specific, but lacking the established psychometric properties. Therefore, a nursing-specific critical thinking test with established psychometric properties would help nurse educators understand the unique critical thinking ability of baccalaureate nursing students. With information from a quantitative critical thinking ability assessment tool, instructional methods could be revised to target student characteristics that correlate with critical thinking ability. Additionally, nurse educators could use the information from a nursing-specific …

Understanding Transitions Of Trust Across Different Business Contexts: An Exploratory Sequential Mixed Methods Study, Sungsik Yoon

UNLV Theses, Dissertations, Professional Papers, and Capstones

Airbnb’s influence has been growing rapidly in the last few years, and hotel operators are beginning to recognize the competitive threat it poses. However, consumers may perceive Airbnb differently than hoteliers. Thus, the current study attempts to explore hotel customers’ perceptions of the sharing economy business (Airbnb). It is important to pay attention to the different business settings of the channels that currently exist in the lodging industry. Moreover, investigating the relationship between trust and perceived risk in this new channel (i.e., Airbnb) is crucial due to the inherent risk of transactions on Airbnb, especially when compared with traditional Business-to-customer. …

Modeling of stress and anxiety in adult zebrafish (Danio rerio) is increasingly utilized in neuroscience research and central nervous system (CNS) drug discovery. Representing the most commonly used zebrafish anxiety models, the novel tank test (NTT) focuses on zebrafish diving in response to potentially threatening stimuli, whereas the light-dark test (LDT) is based on fish scototaxis (innate preference for dark vs. bright areas). Here, we systematically evaluate the utility of these two tests, combining meta-analyses of published literature with comparative in vivo behavioral and whole-body endocrine (cortisol) testing. Overall, the NTT and LDT behaviors demonstrate a generally good cross-test correlation …

Transcranial Direct Current Stimulation And Sports Performance, Dylan J. Edwards, Mar Cortes, Susan Wortman-Jutt, David Putrino, Marom Bikson, Gary Thickbroom, Alvaro Pascual-Leone

Research outputs 2014 to 2021

The application of transcranial direct current stimulation (tDCS) hasmoved fromthe laboratory to the wider community. This form of non-invasive brain stimulation has been shown in a number of controlled animal and human experiments, over nearly five decades, to modulate brain physiology, cognitive functions, and behavior. While its effects are variable across and within individuals, it is not unreasonable to state that tDCS harbors the potential to enhance executive and physical human performance. In a society increasingly driven to succeed with less effort, performance enhancement with an intervention that has an excellent safety record, is well tolerated, relatively inexpensive and readily …

Practicing What You Preach: The Health Behaviors Of Nurses, Catherine Anjali Prabhu

Senior Theses

This research study investigated the relationship between the health behaviors nurses commonly teach to their patients and the behaviors they practice themselves. After receiving the 194 completed surveys, a thorough analysis of variables was completed to determine which educational topics are most frequently included in patient education as well as if these variables are related to the health behaviors nurses practice themselves. It was evident that many nurses who report educating their patients on healthier lifestyles do not implement all of these practices into their own lives. Barriers to implementing such behaviors, employer-provided health programs, and methods of stress reduction …

Functional Limitation And Depressive Symptomatology: Considering Perceived Stigma And Discrimination Within A Stress And Coping Framework, Robyn Lewis Brown

Sociology Faculty Publications

This study examines whether perceived stigma and discrimination moderate the associations between functional limitation, psychosocial coping resources, and depressive symptoms among people with physical disabilities. Using two waves of data from a large community study including a representative sample of persons with physical disabilities (N = 417), an SEM-based moderated mediation analysis was performed. Mediation tests demonstrate that mastery significantly mediates the association between functional limitation and depressive symptoms over the study period. Moderated mediation tests reveal that the linkage between functional limitation and mastery varies as a function of perceived stigma and experiences of major discrimination and day-to-day discrimination, …

Interdependency Of Egf And Glp-2 Signaling In Attenuating Mucosal Atrophy In A Mouse Model Of Parenteral Nutrition, Yongjia Feng, Farok R. Demehri, Weidong Xiao, Yu-Hwai Tsai, Jennifer C. Jones, Constance D. Brindley, David W. Threadgill, Jens J. Holst, Bolette Hartmann, Terrence A. Barrett, Daniel H. Teitelbaum, Peter J. Dempsey

Internal Medicine Faculty Publications

BACKGROUND & AIMS: Total parenteral nutrition (TPN), a crucial treatment for patients who cannot receive enteral nutrition, is associated with mucosal atrophy, barrier dysfunction, and infectious complications. Glucagon-like peptide-2 (GLP-2) and epidermal growth factor (EGF) improve intestinal epithelial cell (IEC) responses and attenuate mucosal atrophy in several TPN models. However, it remains unclear whether these 2 factors use distinct or overlapping signaling pathways to improve IEC responses. We investigated the interaction of GLP-2 and EGF signaling in a mouse TPN model and in patients deprived of enteral nutrition.

METHODS: Adult C57BL/6J, IEC-Egfr^{knock out (KO)} and IEC-pik3r1^KO mice receiving …

We analyzed NCDB 1998–2011 data on medulloblastoma for children ages 0–19 years using logistic and poisson regression, Kaplan–Meier survival estimates, and Cox proportional hazards models. 3647 cases of medulloblastoma in those aged 0–19 years were identified. Chemotherapy was received by 79 and 74% received radiation, with 65% receiving both therapies. Those who received radiation were more likely to be older than four, while those who received chemotherapy were more likely to be age four …

Facilitating Pre-Service Teachers To Learn The Mathematical Practices And Engage English Language Learners, Jim Ewing

Journal of Multicultural Affairs

A methods course attempted to help pre-service teachers facilitate the engagement of English language learners (ELLs) in Mathematical Practices from the Common Core State Standards. When 22 elementary pre-service teachers were taught a mathematics lesson in Spanish, most were unable to make sense of the lesson. This made them more aware of challenges ELLs may face when they attempt to engage in Mathematical Practices. The pre-service teachers developed their own strategies to facilitate ELLs. The findings suggest that pre-service teachers not only better empathized with ELLs after being taught in another language, they also learned Mathematical Practices more deeply.

Schizophrenia And Its Effects On An American Family: A Call To Action For The 21st Century, Cynthia Newton Captain

Senior Theses

Our country’s healthcare system is at a moral crossroads. The way we treat those whom we call “the homeless” is deplorable. The majority of the homeless are mentally ill and need treatment. Our country needs to treat those with the severe brain diseases of schizophrenia, schizo-affective disorder, and bi-polar disorder just as we would Alzheimer’s disease and Parkinson’s disease. Those with severe mental illness, who have no insight into their illness, should not be allowed to dictate their own treatment. If a homeless person is brought to San Francisco General Hospital and is found to be a schizophrenic in psychiatric …

Discussed in the paper are the various methods of communication including PECS, the QWERTY keyboard, and mobile applications. These can be used on an iPad, iPhone, smartphone etc. The nutritional benefit of some foods for children with autism is also a contributing factor of how they act. Eating foods such …

The Experience Of Generalized Anxiety Disorder Through The Lens Of Abraham Lincoln: The Effects Of Mental Health Stigma, Daryl Claude Medina

Senior Theses

Living with generalized anxiety disorder, also known as GAD, in the United States of America is difficult not only for the individual, but also for the people around him or her. Lifestyle changes have to be made, family dynamics need to be adjusted, and last but not least, all relationships must become flexible. In fact, these major life changes are never fixed and must continually adapt to the needs of the individual with generalized anxiety disorder since it is a lifelong medical condition. As with any other mental illness, dealing with generalized anxiety disorder takes great sacrifice in terms of …

The Relationship Between Promoting Self-Efficacy And Informed Decision-Making In Pregnant Nulliparous Women And Method Of Delivery, Crystal Hunter

Senior Theses

This presentation will cover the relationship between the concepts of decreased self-efficacy in pregnant women’s abilities to deliver their babies vaginally, fear of the pain and duration of labor process, and the acceptance of medical intervention without sufficient intrapartum education surrounding delivery methods. These interrelated variables impede the concept of informed choice. The current state of the problem surrounds women with low self-efficacy who are predicted to have negative childbirth experiences such as, consenting to an astronomically high rate of cesarean sections. The focus for nursing is that low-risk, healthy women who elect cesarean sections without the knowledge that permanent …

Dying For A Diagnosis: The Impact Of Racial Discrimination In Healthcare, Danielle Owusu

Senior Theses

Previous studies have found that healthcare providers are affected by unconscious racial bias, reducing the quality of care and outcomes for African American patients (Yearby, 2010). This undergraduate study hypothesized when healthcare providers show more empathy, they provide higher quality care to their patients. Since African Americans face more discrimination on average, their chances for quality care is lower. Results reveal a positive correlation between empathy from healthcare providers and care administered to patients; furthermore, they reveal no significance found in discrimination of African American patients compared to other races. The study consisted of 93% female participants, which affects the …

The Effects Of Chronic Alcohol Consumption On Ovarian Function/ Morphology, Destiny Roberts

Undergraduate Honors Theses

Chronic alcohol (ethanol) consumption has been known to affect the major organs of the body and particularly the liver. However, the effects of chronic ethanol consumption on the female reproductive system remain relatively unstudied. A convenient way to study these effects is by analyzing laboratory mice that have been fed an ethanol diet for an extended period of time and comparing them to control mice. In this study, female mice were separated into control and ethanol fed groups. The mice were placed on their specified diets and observed over the course of six weeks. The mice were fed and weighed …

Curriculum Development Of California Correctional Institution (Cci) Nursing Staff Performance During Simulation Training Related To Cardiac Emergency Response, Dina Wang

Doctoral Projects

The Cycle 4 OIG medical reports published in January 2016 for California Correctional Institution (CCI) noted emergency medical response (EMR) inadequacies. Nursing was specifically called out for EMR care deficits. Chest pain and respiratory distress were amongst the top signs and symptoms identified as having substandard nursing care issues within the report. The cycle 4 OIG medical inspection report gives specific incidences of patient care inadequacies.

As a result of the EMR portion results of the cycle 4 OIG reports, there was a need for improvement planned interventions. The Doctor in Nurse Practice (DNP) project is a quantitative quasi-experimental study …

End Of Life Care Practices For Patients Who Die In Intensive Care Units (Icu), Jila Ghabeljoo

Doctoral Projects

Today, one in five hospital deaths happens in the intensive care unit with the expectation of twice as many by 2030. Increasing, mortality has triggered a growing attention to end-of-life (EOL) care in the ICU. However, the lack of coveted EOL and palliative care skills creates a challenge for ICU nurses. The aim of this study was to assess the current practices of EOL care in the ICU. In this quantitative research, a retrospective chart review method was employed to analyze the collected data from a population 60 EOL patients who died in the ICU of a Southern California hospital. …

Implementing Evidence Based Practices For Preventing Cardiac Implantable Electronic Device (Cied) Infection And The Role Of Post-Operative Oral Antibiotics, Ingrid Mitchell

Doctoral Projects

Cardiac pacemakers and implantable cardioverter defibrillators (ICD) are standard therapy for patients with a bradyarrhythmia, tachyarrhythmia or heart failure (HF) with a left bundle branch block (LBBB) (Wilkoff, et al., 2008). Millions of cardiac implantable electronic devices (CIED) have been implanted worldwide and this clinical practice has improved the quality of life for millions (Epstein, DiMarco, & Ellenbogen, 2008). With the increase of implants there has been an increase in the infection rates (Klug et al., 2007). Research studies have evaluated pre-procedure, during procedure and after procedure risk and protocols. Studies have also evaluated operative factors, procedural related factors, intravenous …

Antimicrobial Stewardship: Incentives And Barriers To Implementation In Skilled Nursing Facilities, Gloria M. Escalona

Doctoral Projects

This study was part of a quality improvement effort of a Skilled Nursing Facility (SNF) to develop and establish an antimicrobial stewardship program to comply with recently enacted California State Senate Bill 361 (SB 361), which went into effect January l, 2017 (Skilled nursing facilities, 2015). The division of the facility into two sections, one staffed largely by Licensed Vocational Nurses (L VNs) and another staffed largely by Registered Nurses (RNs) provided an study opportunity that easily differentiated the licensed nurses. This study used three methods: 1) an educational intervention to licensed nurses, 2) a post-educational intervention survey of licensed …

Molecular Subtyping Of Staphylococcus Aureus Isolates From The U.P. Community For The Presence Of Toxin-Encoding Genes, Carol I. Kessel

All NMU Master's Theses

Staphylococcus aureus is the most common cause of human bacterial infections; however, humans can also be asymptomatically colonized with S. aureus. Asymptomatic carriers can potentially spread S. aureus infection to others. These infections can range from mild to severe. The pathology of a S. aureus infection is often dependent on which toxins are expressed and the virulence factors with which they are associated. One goal of this study was to isolate S. aureus from healthy, consenting adult volunteers who submitted nasal swabs for culture and qRT-PCR analysis to determine which strains are present in the community. This knowledge could …

Role Of Biomechanical Forces In Hyperfiltration-Mediated Glomerular Injury In Congenital Anomalies Of The Kidney And Urinary Tract., Tarak Srivastava, Ganesh Thiagarajan, Uri S. Alon, Ram Sharma, Ashraf El-Meanawy, Ellen T. Mccarthy, Virginia J. Savin, Mukut Sharma

Manuscripts, Articles, Book Chapters and Other Papers

Congenital anomalies of the kidney and urinary tract (CAKUT) including solitary kidney constitute the main cause of progressive chronic kidney disease (CKD) in children. Children born with CAKUT develop signs of CKD only during adolescence and do not respond to renin-angiotensin-aldosterone system blockers. Early cellular changes underlying CKD progression to end-stage renal disease by early adulthood are not well understood. The mechanism of maladaptive hyperfiltration that occurs from loss of functional nephrons, including solitary kidney, is not clear. We re-examine the phenomenon of hyperfiltration in the context of biomechanical forces with special reference to glomerular podocytes. Capillary stretch exerts tensile …
