The Effect of Mentoring Novice Clinical Educators on the Perception of Nursing Students from the Clinical Learning Environment

Introduction: Creating a supportive clinical learning environment (CLE) is one of the characteristics of an effective clinical instructor in nursing. Perhaps empowering novice clinical educators using mentorship method can reduce or resolve this problem. The aim of this study was to determine the impact of the mentorship program for novice clinical educators on the nursing students’ actual and preferred understanding of CLE.Methods: This quasi-experimental study on three groups was conducted as post-intervention with the participation of 139 undergraduate nursing students of Mashhad University of Medical Sciences. Sampling was done via stratified and multistage method. Students were placed in three groups: expert clinical educator (n=47), novice clinical educator (n=51), and mentorship (n=41). In the novice and expert clinical educator groups, training was conducted through the conventional method. In the mentorship group, a novice clinical educator (mentee) and an expert clinical educator (mentor) had a mentoring relationship for two weeks. The Chan (2001) CLE inventory was completed at the end of the first and second weeks of externship. Data were analyzed through SPSS v. 16 software using one-way ANOVAand paired t-tests.Results: The students of the three groups were homogeneous in terms of gender (P=0.101) and level of interest in the field (P=0.278). According to the result of the paired t-test, the difference in the mean score of the actual and preferred CLE at the end of the first week was statistically significant in the novice clinical educators (P=0.008) and the mentorship group (P=0.04); however, after the implementation of mentorship program (at the end of the second week), the difference was significant only in the novice educators group (P=0.001).Conclusion: The implementation of the mentorship program for novice clinical educators (as with the expert educators group) could lead to a reduction in the mismatch between the actual and preferred views of students about the CLE. Thus, it is recommended that this method should be used under conditions of shortage of expert educators to create a supportive CLE

Pre- and post-treatment of α-Tocopherol on cognitive, synaptic plasticity, and mitochondrial disorders of the hippocampus in icv-streptozotocin-induced sporadic Alzheimer’s-like disease in male Wistar rat

ObjectiveMost dementia cases in the elderly are caused by Alzheimer’s disease (AD), a complex, progressive neurological disease. Intracerebroventricular (ICV) administration of streptozotocin (STZ) in rat’s results in aberrant brain insulin signaling, oxidative stress, and mitochondrial dysfunction that impair cognition change neural plasticity, and eventually lead to neuronal death. The current study aims to define the neuroprotective action of alpha-tocopherol in enhancing mitochondrial function and the function of synapses in memory-impaired rats brought on by icv-STZ.MethodsMale Wistar rats were pre-treated with (α-Tocopherol 150 mg/kg) orally once daily for 7 days before and 14 days after being bilaterally injected with icv-STZ (3 mg/kg), while sham group rats received the same volume of STZ solvent. After 2 weeks of icv-STZ infusion, rats were tested for cognitive performance using a behaviors test and then were prepared electrophysiology recordings or sacrificed for biochemical and histopathological assays.ResultsThe cognitive impairment was significantly minimized in the behavioral paradigms for those who had taken α-Tocopherol. In the hippocampus of icv-STZ rat brains, α-Tocopherol ocopherol effectively prevented the loss of glutathione levels and superoxide dismutase enzyme activity, lowered mitochondrial ROS and mitochondrial membrane potential, and also brought about a decrease in Aβ aggregation and neuronal death.ConclusionOur findings demonstrated that by lowering neurobehavioral impairments caused by icv-STZ, oxidative stress, and mitochondrial dysfunction, α-Tocopherol enhanced intracellular calcium homeostasis and corrected neurodegenerative defects in the brain. These findings examine the available approach for delaying AD connected to mitochondrial malfunction and plasticity issues

Nursing student abilities concerning their performance in nursing disaster

Introduction: Capability of the rescue team in all aspects can reduce mortality and morbidity rate. Nurses therefore should be well educated and fully trained to be able to perform efficiently in disaster as a main part of the rescue team. Objective: The current survey was done in 2005, aiming to determine nursing student’s abilities of performing in disaster. Method: This descriptive survey was done on 50 students chosen with proportional sampling method. The students were at first and last grade of B.S nursing course. Data were collected self reporting, using researchers made tools of demographics data, awareness determination and ability investigation forms. Data were analyzed using t-test and chi square methods. Results: Awareness of students of their role in 3 stages of disaster were different among the first and last year students (t=0.5, p<0.0001) but self reported professional abilities were not statistically significant (t=2.84, p=0.68) Conclusion: The current survey shows that while the students' awareness has improved, their abilities have not significantly changed. The findings suggested that disaster nursing curriculum should be emphasizing practical aspects. Keywords: Knowledge, Performance, Nursing Students, Disaster, Nurses Rol

Outcomes of Patient Education in Nurse-led Clinics: A Systematic Review

Introduction: Patient education is an independent role of nurses performed in nurse-led clinics (NLCs). The measurement of patient education outcomes validates whether nursing educational interventions have a positive effect on patients, which helps determine whether changes in care are needed. Standardized nursing terminologies facilitate the evaluation of educational outcomes. We aimed to explore the outcomes of patient education in NLCs based on the Nursing Outcome Classification (NOC) system. Methods: The review was conducted according to PRISMA guidelines. We searched "Medline", "Embase", "Web of Science", and "Scopus" databases for articles published between 2000 and 2022. Based on the search strategy, 1157 articles were retrieved from PubMed, Scopus, Web of Science, and Embase databases. After excluding the duplicates, 978 articles were appraised. 133 articles remained after reading the titles and abstracts of the articles. In the next step, the articles were evaluated regarding methodology, research population, and exclusion criteria, after which 112 articles were omitted, and finally, 21 articles were included in the full-text review. We assessed all included studies using the Quality Assessment of Controlled Intervention Studies checklist. Results: A total of 21 randomized controlled trials met the inclusion criteria. "Physiologic health", "functional health", "psychosocial health", "health knowledge and behavior", and "perceived health" were the domains of nursing outcomes investigated as Patient Education Outcomes in NLCs. Conclusion: Most of the outcomes were linked to lifestyle-related chronic diseases and, further studies are needed to determine the effects of patient education provided in NLCs in terms of family/society health outcomes

Background: To make the best use of written information in education pamphlets, suitability criteria developed for instructional materials. Moreover, client satisfaction with the quality of written materials provided in hospitals for patients needs to be taken into account. Aim: Therefore, the present study aimed to assess the suitability of patient education pamphlets and patient satisfaction among teaching hospitals in Mashhad, Iran. Method: A total number of 542 patient education pamphlets developed in 11 teaching hospitals in Mashhad was collected via a census method and their suitability was investigated using Suitability Assessment of Materials (SAM) instrument. Subsequently, satisfaction with education pamphlets among 2820 hospitalized patients was evaluated using a questionnaire designed based on SAM instrument. The association between the suitability of the given pamphlets and patient satisfaction was also determined. Descriptive statistics and the Chi-square test were used to analyze the findings. Results: The results revealed that 33.3% and 66.7% of the given pamphlets fell into the superior and adequate categories in terms of suitability, respectively. With regard to the satisfaction level, 0.7%, 26.4%, and 72.9 % of the patients were poorly, fairly, and completely satisfied with the pamphlets, respectively. Moreover, the pamphlets rated the higher suitability by patients obtained the higher satisfaction scores. Implications for Practice: The results of this study indicated a need for reconsiderations in some suitability factors for the pamphlets. In this respect, the factors of cultural appropriateness as well as layout and typography rated as acceptable

Effects of a School-Based Interventional Program on Smoking Refusal Self-efficacy in Adolescent Females

smoking. Self-efficacy can be assumed as the best predictor of smoking behavior in adolescents. Aim: The present study aimed to investigate the effects of a school-based interventional program on smoking refusal self-efficacy in adolescent females. Method: This randomized controlled trial was conducted on 53 adolescent females in 2017. The participants were randomly divided into two groups of intervention (n=27) and control (n=26). The intervention group was provided with a smoking prevention program implemented five sessions a week in their school classrooms. On the other hand, the control group received the routine interventions. A researcher-made Smoking Refusal Self-Efficacy Questionnaire was completed before and one month after the intervention. Statistical analysis was performed in SPSS software (version 20.0) using Fisher’s exact test, t-test, and Mann-Whitney U test. Results: According to the results, 9 (34.6%) and 7 (25.9%) individuals in the control and intervention groups had smoking fathers, respectively. The two study groups were homogeneous in terms of smoking refusal self-efficacy before the intervention. Following the intervention, the mean self-efficacy scores in the intervention and control groups were estimated as 111.55±13.1 and 93.53±25.02, respectively. There was a significant difference between the two groups regarding this variable after the intervention (P=0.02). Implications for Practice: The school-based interventional program for smoking prevention in accordance with social skills training could effectively increase the level of smoking refusal self-efficacy in adolescent females
