Personality portraits, resilience, and professional identity among nursing students: a cross-sectional study.

BACKGROUND: The lack of professional identity can impede the transition from nursing students to qualified nurses and exacerbate the shortage of health care professionals. Personality is important to resilience-building and professional identity development in nursing students. However, the associations among personality, resilience, and professional identity are less explored. The study aims to identify latent subtypes of personality, to evaluate the mediating role of resilience between personality and professional identity in nursing students, and to provide practical guidance for educators' subsequent interventions with nursing students' professional identity. METHODS: 1397 nursing students were recruited from Be Resilient to Nursing Career (BRNC) between October 2020 and April 2022 by cluster sampling from 4 universities in China. NEO Five-Factor Inventory, 10-item Connor-Davidson Resilience Scale, and Professional Identity Questionnaire for Undergraduate Students were administered. Analyses of latent profiles and mediations were performed. RESULTS: Three latent personality types were identified: Over-sensitivity (35.4%), Ordinary (53.8%), and Flexibility (10.8%). Nursing role model was found to be a significant indicator of personality (Ordinary as ref, Over-sensitivity: OR = 0.73, 95% CI: 0.57-0.93, P = 0.010; Flexibility: OR = 1.85, 95% CI: 1.29-2.65, P = 0.001). The association between personality portraits and professional identity were significantly mediated by resilience (P < 0.05). CONCLUSIONS: There exists heterogeneity in nursing students' personality. Resilience plays a significant role in mediating the relationship between personality and professional identity.

Association between circadian rhythm and sleep quality among nursing interns: A latent profile and moderation analysis.

Background: Disturbances in circadian rhythms are common among night-shift workers and result in poor sleep quality. Nevertheless, the heterogeneity of circadian rhythms and their relationship with sleep quality is less explored in nursing interns. Therefore, we aimed to identify the latent subtypes of circadian rhythm, explore their relationship with sleep quality, and evaluate their moderating role between perceived stress and sleep quality in nursing interns. Materials and methods: In all, 452 nursing interns were recruited between October 2020 and January 2021 from Be Resilient to Nursing Career (BRNC), which is a multicenter, prospective cohort of a career growth program for nursing students. They were assessed using the 10-item Chinese Perceived Stress Scale, Circadian Type Inventory, and Pittsburgh Sleep Quality Index. Latent profile analysis and moderation analysis were performed. Results: Overall, 72.3% of the nursing interns reported poor sleep quality. We identified three latent subtypes of circadian rhythms, namely, Vigorousness (40.1%), Inadaptability (18.6%), and Flexibility (41.1%). Females (OR = 1.97, 95% Cl: 1.01-3.83, P = 0.047) with normal body mass index (OR = 1.62, 95% CI: 0.95-2.76, P = 0.078) were prone to Flexibility. Circadian rhythm types significantly moderated the association between perceived stress and sleep quality (P < 0.05). Conclusion: Nursing interns suffer from poor sleep. There exists heterogeneity of circadian rhythm subtypes in nursing interns, and attention should be paid to those with Inadaptability type. The association between perceived stress and sleep quality is significantly moderated by circadian rhythm subtypes.

Stress/Resource Complex, Sense of Coherence and Professional Identity Among Nursing Students: A Latent Profile and Mediation Analysis.

Purpose: Sense of coherence is significant to mental health and professional development in nursing students. However, the association among stress/resource complex, sense of coherence, and professional identity is less explored in nursing students. This study was designed to identify latent subtypes of stress/resource complex and to evaluate the mediating role of sense of coherence between stress/resource complex types and professional identity in nursing students. Participants and Methods: A total of 595 nursing students were recruited from Be Resilient to Nursing Career (BRNC) between October and December 2021 and administered with 10-item Connor-Davidson Resilience Scale, General Self-efficacy Scale, 10-item Chinese Perceived Stress Scale, 13-item Sense of Coherence Scale, and Professional Identity Questionnaire for Undergraduate Students. Latent profile analysis and mediation analysis were performed. Results: Three latent subtypes of stress/resource complex were identified: Flexibility (14.8%), Ordinary (44.2%), and Maladjustment (41.0%). Nursing students with role model were prone to Ordinary (OR = 1.48, 95% CI 1.03-2.13, p = 0.035) and Flexibility (OR = 1.92, 95% CI 1.17-3.16, p = 0.011). The association between stress/resource complex types and professional identity was mediated by sense of coherence (P < 0.05). Conclusion: There exists heterogeneity in nursing students' stress/resource complex. The association between stress/resource complex subtypes and professional identity was mediated by sense of coherence.

Analysis of the Need for Postoperative Drainage Application for Hip Arthroplasty: A Systematic Review and Meta-Analysis.

OBJECTIVE: To synthesize the evidence regarding the effect and safety of drainage after the hip arthroplasty in randomized control trials. BACKGROUND: Although the standard of hip replacement has matured in recent years, the need for postoperative drainage is still controversial which also is a clinical problem that needs to be addressed. DESIGN: A systematic review and meta-analysis based on the Cochrane methods and Prisma guideline. Data Resources. A systematic search of the Cochrane Library, PubMed, EMBASE, CINAHL, Ovid, Wan Fang database, CNKI, and CBM database was carried out from January 1, 2000, to December, 2021. Review Methods. The quality of included randomized controlled trials was assessed individually by two reviewers independently using criteria recommended in the Cochrane Handbook for Systematic Reviews of Interventions 5.1.0. RESULTS: Nineteen randomized control trials involving 3354 participants were included in this analysis. From the above analysis, we can know that compared with nondrainage, there was a statistically significant difference in VAS score on the postoperative first day (SD = -0.6; 95% CI: -0.79, -0.41) and second day (SD = -0.38, 95% CI: -0.58, -0.18), hematocrit reduction (MD =2.89; 95% CI: 1.3, 4.48), blood transfusion rate (OR =1.47; 95% CI: 1.12, 1.92), change of thigh circumstance (SMD = -0.48; 95% CI: -0.66, -0.31), and hospital stay (MD = 1.06; 95% CI: 0.73, 1.39) in drainage. However, there were no statistically significant differences in hemoglobin and hematocrit level, hip function, total blood loss, transfusion volume, dressing use, and complications between them. CONCLUSION: Drainage after hip arthroplasty can reduce swelling in the thigh and relieve pain while no drainage can bring down hematocrit reduction, decrease dressing uses, and shorten the hospital stay which promotes rapid recovery. This review provides a detailed theoretical reference for the proper clinical application of drains and improves the efficient use of resources.

Threshold Effect of Foreign Direct Investment and Carbon Emissions Performance From the Perspective of Marketization Level: Implications for the Green Economy.

Exploring the path and mechanism of marketization level in the effect of foreign direct investment (FDI) on carbon emission performance will help to maximize the stimulation effect of foreign investment on green and low-carbon development. This study used the panel data of 11 provinces and cities in the Yangtze River Economic Belt from 2008 to 2016. A panel threshold model is constructed to explore the non-linear relationship between FDI and carbon emissions performance from the perspective of marketization level. The main conclusions are as follows: First, from the perspective of marketization level, a significant double threshold effect exists between foreign participation and carbon emission intensity, with threshold values of 4.4701 and 9.2516 respectively. Second, as the marketization level increases, the technology spillover effect of FDI increases, and the stimulation effect of foreign participation on carbon intensity decreases significantly, but it does not inhibit carbon intensity, indicating that the overall benefits brought by FDI technology spillovers are still insufficient to offset pollution caused by foreign investment. Third, the eastern region of the Yangtze River Economic Belt has crossed the second threshold. In the central and western regions, the marketization process is relatively slow except for Chongqing, and the regions are still firmly stuck between the first and second thresholds. In response to the conclusions of the empirical research, relevant policy suggestions are put forward from three dimensions, namely, the strategy of introducing foreign investment, construction of the marketization system, and environmental regulation, to achieve low-carbon and green development in the Yangtze River Economic Belt.
