Background: Situation, background, assessment, and recommendation (SBAR) has been extensively used in clinical and nursing education. A structured communication program increases effective communication, positivity, and education satisfaction during inter-professional collaboration among nursing students. This systematic review aimed to identify and synthesize evidence on the effectiveness of SBAR-based simulation training for nursing students. Methods: A research protocol was developed according to the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols guidelines. The protocol for this study was registered in PROSPERO (CRD42021234068). Eight bibliographical databases were searched for studies published between 2001 and 2021, using relevant search terms. Searches were conducted in PubMed, Embase, Cumulative Index to Nursing and Allied Health, and Cochrane Central Register of Controlled Trials for literature in English, and DBpia, Research Information Sharing Service, Korean Studies Information Service System, and Korea Institute of Science and Technology Information for literature in Korean. After screening titles, abstracts, and full-text papers, pertinent data were extracted, and critical appraisals of the retrieved studies were performed. Data were analyzed using the framework approach, and the findings were presented in a narrative summary. The Effective Public Health Practice Project “Quality Assessment Tool for Quantitative Studies” was used to assess the quality of the included studies. Results: Twelve studies were included: 3 randomized controlled trials and 9 quasi-experimental studies. Two overarching themes were noted, namely communication clarity and critical thinking. The results of six out of 12 studies produced significant results in favor of SBAR-based simulation in terms of communication clarity. Divergent results were obtained regarding communication ability, critical thinking, confidence, learning self-efficacy, and attitude toward patient safety. The results of these studies highlight that communication clarity ultimately leads to positive results in terms of nursing students’ behaviors related to patient safety. Conclusions: This review provides a comprehensive update of the literature on the effectiveness of SBAR-based nursing simulation programs for nursing students. These programs were found to have positive learning outcomes because of clear and concise communication. Further studies on the effectiveness of various learning outcomes derived from SBAR-based programs are required.

Purpose: Silent information regulator 1 (SIRT1) in the brain is essential for maintaining cellular homeostasis and plays a neuroprotective role in cerebral ischemia and neurodegenerative disorders. The effect of preischemic treadmill exercise on chronic cerebral hypoperfusion (CCH)-induced spatial learning memory impairment, microvascular injury, and blood-brain barrier (BBB) disruption in relation with SIRT1 expression was evaluated.Methods: Prior to bilateral common carotid artery occlusion (BCCAO) surgery, the rats in the exercise groups performed low-intensity treadmill running for 30 minutes once daily during 8 weeks. BCCAO surgery was performed on male Wistar rats at 12 weeks of age. Spatial learning memory was measured using the Morris water maze test. Neuronal nuclear antigen, SIRT1, and rat endothelial cells antigen 1 were determined by immunohistochemistry and platelet-derived growth factor receptor beta was determined by immunofluorescence.Results: Preischemic treadmill exercise ameliorated spatial learning memory impairment and enhanced SIRT1 expression in the BCCAO rats. Preischemic treadmill exercise ameliorated BCCAO-induced damage to microvasculature and pericytes that make up the BBB. The effect of preischemic treadmill exercise was lost with sirtinol treatment.Conclusions: These results can apply treadmill exercise prior to cerebral ischemia as a rational preventive and therapeutic intervention strategy to improve cognitive dysfunction in CCH patients.

Epigenetic age acceleration has been studied as a promising biomarker of age-related conditions, including cognitive aging. This pilot study aims to explore potential cognitive aging-related biomarkers by investigating the relationship of epigenetic age acceleration and cognitive function and by examining the epigenetic age acceleration differences between successful cognitive aging (SCA) and normal cognitive aging (NCA) among Korean community-dwelling older adults (CDOAs). We used data and blood samples of Korean CDOAs from the Korean Frailty and Aging Cohort Study. The participants were classified into two groups, SCA (above the 50th percentile in all domains of cognitive function) and NCA. The genome-wide DNA methylation profiling array using Illumina Infinium MethylationEPIC BeadChip was used to calculate the following: the DNA methylation age, universal epigenetic age acceleration, intrinsic epigenetic age acceleration (IEAA), and extrinsic epigenetic age acceleration (EEAA). We also used Pearson correlation analysis and independent t-tests to analyze the data. Universal age acceleration correlated with the Frontal Assessment Battery test results (r = −0.42, p = 0.025); the EEAA correlated with the Word List Recognition test results (r = −0.41, p = 0.027). There was a significant difference between SCA and NCA groups in IEAA (p = 0.041, Cohen’s d = 0.82) and EEAA (p = 0.042, Cohen’s d = 0.78). Epigenetic age acceleration can be used as a biomarker for early detection of cognitive decline in Korean community-dwelling older adults. Large longitudinal studies are warranted.

Background: This pilot study aimed to investigate the effects of developing scenario learning (DSL) on team efficacy, systems thinking, and proactivity in problem-solving in a fundamental nursing course. Methods: A total of 53 second-year nursing students were enrolled in the study; the DSL nursing education program was implemented for 15 weeks from March 4 to June 17, 2021. Data on team efficacy, systems thinking, and proactivity in problem-solving were measured before and after the DSL-based nursing education program. The collected data were analyzed using the IBM SPSS Statistics version 22.0. Results: The results demonstrated that nursing students’ team efficacy (t = − 8.228, p < .001, Cohen’s d = 1.079), systems thinking (t = − 9.757, p < .001, Cohen’s d = .731), and proactivity in problem-solving (t = − 8.635, p < .001, Cohen’s d = .992) significantly increased after the program. Conclusions: The findings of this study can contribute to the development of nursing competency in nursing students without experience in nursing practicum. The authors recommend incorporating DSL in the nursing curriculum to promote early adaptation in clinical settings.

Older adults suffer from multiple symptoms, which negatively affects their health-related quality of life. The single-symptom management approach has been less than effective. The data of 2362 Korean community-dwelling older adults aged 70 and above were analyzed in the Korean Frailty and Aging Cohort Study (KFACS) study. A cluster analysis, correlation analysis, and logistic regression were used to analyze the data. We found three symptom clusters: high symptom burden (HSB, n = 1032); pain and fatigue group (PAF, n = 566); and the sleep deprivation group (SDP, n = 764). Participants in the HSB group are more likely to be of old age (OR = 1.1), be female (OR = 2.4), live in a rural area (OR = 1.4), have low physical activity (OR = 0.9), and have multiple chronic conditions (OR = 1.5). The clinical blood markers analysis showed a negative relationship among the physical health, free T4 (r = −0.083, p < 0.01) and insulin (r = −0.084, p < 0.01). The sex-specific blood markers analysis showed differences among three clusters. While free testosterone (male: r = 0.124, female: r = 0.110, p < 0.05) and dehydroepiandrosterone (DHEA) (male: r = 0.352 and female: r = 0.134, p < 0.05) were associated with physical health in the HSB group, only free testosterone was associated with mental health (male: r = −0.093, and female: r = −0.116, p < 0.05) in the SDP group. These findings suggest the potential role of the patient’s sex and sex hormones in symptoms of Korean community-dwelling older adults. Understanding the symptom profiles and impact of biopsychosocial factors may enhance precision symptom management.

Background/Objectives: This study evaluates the effects of a personalized exercise program on symptoms (pain, fatigue, sleep, cognitive function, physical function), resilience, and health-related quality of life (HRQOL) and compares the effectiveness of in-person versus telehealth delivery. Methods: A secondary data analysis was conducted on two 12-week randomized control pilot studies for solid tumor cancer survivors. One study involved in-person home visits with telephone follow-ups. The second utilized weekly exercise recommendations via a smartphone app. Both studies had control participants who received the standard care. Symptoms, resilience, and HRQOL were measured at baseline and after 12 weeks. Paired t-tests were conducted for intervention effects and ANCOVA for group differences, adjusting for age and education. Results: The analysis included 75 program completers: 15 in-person (iHBE), 38 telehealth (TEHE), and 22 who received standard care. Those receiving exercise interventions reported improvements in physical (t = 3.0, p < 0.01) and mental fatigability (t = 3.1, p < 0.01) at program completion compared to baseline. Comparing the mean changes between participants receiving exercise interventions in-person and via telehealth, there were no significant differences between the two delivery methods except perceived visuo-perceptual cognitive difficulty (F = 3.55, p = 0.027), where telehealth showed a slight advantage. Conclusions: The study provides initial evidence of the effectiveness of a telehealth personalized exercise on fatigability and cognitive difficulty, suggesting it is a potential viable alternative to in-person intervention. Further research with a larger cohort is essential to ascertain the effects of these interventional modalities on cancer-related health outcomes.
