Relationship between job stress/sleep quality and job satisfaction among programmers in a Shanghai Internet enterprise / 上海预防医学

ObjectiveTo study the relationship between occupational stress/sleep quality and job satisfaction of internet enterprise programmers， to explore the mediating effect of sleep quality between occupational stress and job satisfaction， and to provide a theoretical basis for taking effective measures to improve job satisfaction. MethodsA total of 271 programmers from an Internet company in Shanghai were investigated by job content questionnaire， Pittsburgh Sleep Index Scale and the third part of the McLean occupational stress questionnaire. The results were statistically analyzed ResultsThe positive rate of occupational stress of programmers in this enterprise was 66.7%， 34.3% of them had average sleep quality， 28.0% had poor sleep quality， and the score of job satisfaction was 47.70±6.78. Correlation analysis showed that the higher the occupational stress， the worse the sleep quality and the lower the job satisfaction. Effects of occupational stress and sleep quality on job satisfaction were both statistically significant. The total effect of occupational stress on job satisfaction was -0.35， and the mediating effect of sleep quality between occupational stress and job satisfaction was -0.04， accounting for 12.0% of the total effect. ConclusionSleep quality of internet enterprise programmers plays a partial mediating role between occupational stress and job satisfaction， and a series of measures such as improving sleep can be taken to improve programmer’s job satisfaction.

Construction of work-related stress risk management index system for medical personnel in China based on Delphi method / 环境与职业医学

Background Despite the growing occupational stress of medical personnel, there is no occupational stress risk management index system for medical personnel in China, and the related risk management work is unfounded. Objective To construct a work-related stress risk management index system for medical personnel in China based on Delphi method. Methods On the basis of literature review and expert interview, an index pool of work-related stress risk management for medical personnel was preliminarily constructed. Through two-round Delphi method, experts' opinions on the importance, operability, familiarity, and judgment basis of candidate indicators were collected, and an index system for work-related stress risk management of medical personnel was constructed. Results Fifteen expert opinions were collected in each of the two rounds, with a recovery rate of 100%. The expert authority coefficients were all >0.9. In the first round, the importance score was 9.78±0.35, the coefficient of variation was 0-0.22, and the Kendall coordination coefficient was 0.215 (P<0.01); in the second round, the importance score was 9.82±0.26, the coefficient of variation was 0-0.13, and the Kendall coordination coefficient was 0.208 (P<0.01). Finally, the index system of work-related stress risk management for medical personnel was composed of 10 first-level indexes, 28 second-level indexes, and 47 third-level indexes. The 10 first-level indexes were job demand, job control, organizational support, interpersonal relationships, role conflict, doctor-patient conflict and medical disputes, work-life conflict, professional self-identity, workplace environment, and social environment, respectively. Conclusion A preliminary refined work-related stress risk management index system for medical personnel in China has been established, but the indicators will be further modified by verification and application of the indicator system.

Predictors for the Bronchiolitis Obliterans Syndrome in Lung Transplant Patient / 中国肺癌杂志

Lung transplantation is the ultimate treatment of end-stage lung disease. After transplantation, the 1-year survival rate is 80%, while the 5-year survival rates remaines at around 50% mainly due to bronchiolitis obliterans syndrome (BOS). BOS is regarded as a fibrosing process in the small airways leading to irreversible airway obstruction. A lot of factors are involved in the development of BOS, such as Ischemia/reperfusion injury, infections, oxidative stress, and acute rejection, etc. Studies have shown that early diagnosis of BOS may improve outcome. It is valuable for the long-term survival of lung transplantation to find out several predictors for the BOS. This article reviews the current state of knowledge on predictors for BOS.
