Professional identity, job satisfaction, and turnover intention among Chinese novice nurses: A cross-sectional study.

The world is faced with challenges due to a growing aging population and the increasing burden of chronic disease. The acute shortage of nurses and high turnover rates, particularly among novice nurses, are of great concern in many countries. Several studies have shown that turnover intention among nurses is influenced by professional identity and job satisfaction. However, to the best of our knowledge, no studies have examined this issue in the context of novice nurses. Thus, the present study aimed to explore the relationship between professional identity, job satisfaction, and turnover intention among novice nurses in China. From March 18 to April 23, 2022, a cross-sectional survey was carried out involving 532 novice nurses recruited from four public hospitals in Sichuan Province, China. Among the sample, 526 questionnaires were retrieved, with an effective response rate of 98.87%. The mean scores for turnover intention, professional identity, and job satisfaction were 13.02 ±â€…3.94, 36.17 ±â€…7.98, and 111.02 ±â€…21.46, respectively. High turnover intention was observed among novice nurses, of whom 54.37% (286/526) had high or very high turnover intention. Professional identity and job satisfaction among novice nurses were moderate. In terms of demographic characteristics, "Whether living with relatives" and "Monthly income" had a statistically significant impact on the turnover intention of novice nurses (P < .05). Both professional identity (r = -0.459) and job satisfaction (r = -0.517) were significantly and moderately negatively correlated with turnover intention (P < .01). The results of the multivariate linear regression analysis revealed that variables including "Whether living with relatives," "Professional identity," "Control and responsibility for work," and "Benefits" jointly accounted for 29.9% of the variance related to turnover intention among novice nurses. "Whether living with relatives," "Professional identity," "Control and responsibility for work," and "Benefits" were highly predictive of turnover intention levels among novice nurses. Hence, potential predictors of turnover intention should be considered, and intervention research should be conducted to reduce the level of turnover intention among novice nurses.

Mechanisms of motor symptom improvement by long-term Tai Chi training in Parkinson's disease patients.

BACKGROUND: Tai Chi has been shown to improve motor symptoms in Parkinson's disease (PD), but its long-term effects and the related mechanisms remain to be elucidated. In this study, we investigated the effects of long-term Tai Chi training on motor symptoms in PD and the underlying mechanisms. METHODS: Ninety-five early-stage PD patients were enrolled and randomly divided into Tai Chi (n = 32), brisk walking (n = 31) and no-exercise (n = 32) groups. At baseline, 6 months and 12 months during one-year intervention, all participants underwent motor symptom evaluation by Berg balance scale (BBS), Unified PD rating-scale (UPDRS), Timed Up and Go test (TUG) and 3D gait analysis, functional magnetic resonance imaging (fMRI), plasma cytokine and metabolomics analysis, and blood Huntingtin interaction protein 2 (HIP2) mRNA level analysis. Longitudinal self-changes were calculated using repeated measures ANOVA. GEE (generalized estimating equations) was used to assess factors associated with the longitudinal data of rating scales. Switch rates were used for fMRI analysis. False discovery rate correction was used for multiple correction. RESULTS: Participants in the Tai Chi group had better performance in BBS, UPDRS, TUG and step width. Besides, Tai Chi was advantageous over brisk walking in improving BBS and step width. The improved BBS was correlated with enhanced visual network function and downregulation of interleukin-1ß. The improvements in UPDRS were associated with enhanced default mode network function, decreased L-malic acid and 3-phosphoglyceric acid, and increased adenosine and HIP2 mRNA levels. In addition, arginine biosynthesis, urea cycle, tricarboxylic acid cycle and beta oxidation of very-long-chain fatty acids were also improved by Tai Chi training. CONCLUSIONS: Long-term Tai Chi training improves motor function, especially gait and balance, in PD. The underlying mechanisms may include enhanced brain network function, reduced inflammation, improved amino acid metabolism, energy metabolism and neurotransmitter metabolism, and decreased vulnerability to dopaminergic degeneration.
