Nurse turnover is one of the reasons for the global nurse shortage. Although previous studies have examined the determinants of turnover intention in detail, there is limited knowledge on the effect of subjective social status on nurse turnover intention. Therefore, in this study, we examined this relationship, including job satisfaction as a mediator, among Chinese nurses. This cross-sectional study employed questionnaires to assess subjective social status, job satisfaction, and turnover intention in 581 nurses who were randomly recruited from 10 hospitals in Jinan, China. The results partially supported our model. Although subjective social status exerted no significant direct effect on turnover intention, it exerted a significant indirect effect through job satisfaction. These results provide a new insight into why nurses leave their jobs, and possible new solutions to the nurse turnover problem. Efforts should be made to improve nurses' subjective social status.

Antimicrobial activities of nisin, tea polyphenols (TPs), and chitosan, and their combinations were evaluated against both Gram-positive bacteria (GPB) and Gram-negative bacteria (GNB) by the agar dilution method. Results showed that the MIC of nisin was 2.44 to 1250 mg/L for GPB and reached 5000 mg/L for GNB. The MICs of TPs and chitosan were 313 to 625 mg/L and 469 mg/L for GNB, and 156 to 5000 mg/L and 234 to 938 mg/L for GPB, respectively. These results indicated that TPs and chitosan exhibited inhibitory effects against both GPB and GNB, whereas nisin inhibited the growth of GPB only. Based on the orthogonal test of their MICs, and evaluation of preservative effect and sensory attributes in chilled mutton, the optimum combination was chosen as 0.625, 0.313, and 3.752 g/L for nisin, TPs, and chitosan, respectively. By using the optimum treatment, the shelf life of chilled mutton was extended from 6 to 18 d at 4 °C in the preservative film packages. These results indicate that the combination of nisin, TPs, and chitosan could be used as preservatives to efficiently inhibit the growth of spoilage microorganisms and pathogens in meat, thus improving the safety and shelf life of chilled mutton.

Background/Aims: While systolic blood pressure variability (SBPV) is an independent risk factor for mortality in the general population, its association with outcomes in hemodialysis patients has been less well-investigated. Methods: In this retrospective study, we enrolled 99 eligible HD patients from 2006 to 2016. Predialysis blood pressure measurements obtained over 1-year period were used to determine each patient’s BPV. The standard deviation (SD), the coefficient of variation (CV) and the variation independent of the mean (VIM) were used as metrics of BPV. Results: During a median follow-up period of 68 months, 52 patients died, and cardiovascular disease (31.3%) was the primary cause of death in these patients. After adjusting for covariates, the hazard ratios (HRs) for all-cause and cardiovascular mortality were 1.80 (95% confidence interval (CI) 1.11-2.92) and 1.71 (95% CI 1.01-2.90), respectively, for a one percent increase in CV. Variability in the volume removed per session and predialysis serum albumin and calcium levels were identified as factors associated with BPV. Conclusion: In this study, we demonstrate that greater variability in predialysis SBP is associated with long-term mortality in hemodialysis patients. Controlling volume variation, avoiding hypoalbuminemia and reducing blood calcium levels might reduce SBP variability and thereby improve prognoses in these patients.

SMS obtained short-term success in improving salt restriction, regular performance of HBPM and medication adherence, which led to better BP control.
