Background Prehospital emergency medical personnel (PEMP) are exposed to long-term high-pressure work, which can exacerbate psychological distress and impair job satisfaction and sleep quality. However, in-depth research on the interactions among these factors is lacking. Objective To assess the status of psychological distress, job satisfaction, and sleep quality of PEMP in Guangzhou and to explore the mediating role of sleep quality in the relationship between psychological distress and job satisfaction. Methods From February to May 2025, 1085 PEMP from "120" emergency network hospitals in Guangzhou were selected using convenience sampling. Data were collected via the General Information Questionnaire, Kessler Psychological Distress Scale, Minnesota Satisfaction Questionnaire, and Pittsburgh Sleep Quality Index. Statistical analyses were performed using SPSS 25.0, and The mediation model of sleep quality in linking psychological distress and job satisfaction was constructed using AMOS 28.0. The bias-corrected Bootstrap method was employed to assessed the significance of the mediating effect. Results A total of 1063 valid responses were received (97.97% valid response rate). The mean scores were: psychological distress (27.99±10.75), job satisfaction (69.45±15.84), and sleep quality (9.82±4.47). Significant differences in the three scores were found across gender, age, monthly night shift frequency, and hospital grade (P<0.05). Higher job satisfaction was linked to lower psychological distress and better sleep quality and its dimensions, while psychological distress directly correlated with poorer sleep quality (P<0.01). Sleep quality partially mediated the relationship between psychological distress and job satisfaction, with a mediating effect of −0.195, accounting for 43.62% of the total effect. Conclusion The participants report moderate psychological distress, moderate-to-high job satisfaction, and poor sleep quality. Psychological distress directly affects job satisfaction and indirectly through its impact on sleep quality. Interventions aimed at improving sleep health and mental health are essential to improve personnel well-being and work efficiency.

In the context of the prevention and control for coronavirus disease (COVID), public health emergency governance has been incorporated into an important part of the national governance system, and the "combination of peacetime and wartime" has become an important principle of public health emergency governance. Based on the experience of public health emergency management in large cities and the theory of collaborative governance, this study analyzed the problems and obstacles of general hospitals in coping with emerging respiratory infectious diseases. It is proposed to select general hospitals above tertiary level in the region to build peacetime and wartime combined emergency hospital, establish standardized conversion procedures and strengthen the construction of key elements of integrated emergency hospitals, so as to provide new ideas for the construction of emergency medical system "combination of peacetime and wartime" mechanism and improve the "combination of civilian and combat" public health emergency governance system.

Objective:To explore the predictive value of pre-biopsy serum inflammatory markers on positive prostate biopsy results, establish a nomogram model based on pre-biopsy inflammatory markers combined with other parameters, and evaluate its predictive ability for prostate biopsy results.Methods:The clinical data of 601 patients undergoing transperineal prostate biopsy who were admitted to the Second Hospital of Tianjin Medical University from August 2019 to August 2021 were retrospectively analyzed. The median age was 68(35, 89)years, and the median tPSA was 9.56(4.01, 19.95)ng/ml. The median fPSA was 1.36(0.88, 2.02)ng/ml, the median PSAD was 0.16(0.11, 0.26)ng/ml 2, and the median platelet-to-lymphocyte ratio(PLR)was 129.90(98.95, 169.89). PI-RADS v2.1 score<3 points in 189 cases(31.45%), 3 points in 174 cases(28.95%), 4 points in 190 cases(31.61%), and 5 points in 48 cases(7.99%). A simple randomization method was used to obtain 421 cases(70.00%)in the modeling group and 180 cases(30%)in the validation group.There was no significant difference in the clinical data between the two groups ( P>0.05). Univariate and multivariate logistic regression analysis were performed in the modeling group to screen independent influencing factors for the prediction of positive prostate biopsy results. A nomogram model was established and internal verification was conducted. External validation of the model was performed in the validation group. Receiver operating characteristic(ROC)curve was used to verify model discrimination, Hosmer-Lemeshow goodness-of-fit test was used to verify model calibration, and decision curve analysis (DCA) was used to evaluate the net benefit and clinical utility of the predictive model. Results:The results of univariate analysis showed that the age( OR=1.060, P<0.01), histological inflammation( OR=0.312, P<0.01), the number of biopsy needles( OR=0.949, P=0.009), f/tPSA( OR=0.954, P=0.003), PV( OR=0.973, P<0.01), PSAD( OR=29.260, P<0.01), PI-RADS v2.1 score(3-point OR=3.766, P=0.001; 4-point OR=11.800, P<0.01; 5-point OR=57.033, P<0.01), lymphocyte count( OR=1.535, P=0.013), NLR( OR=0.848, P=0.044), PLR( OR=0.994, P=0.005)and SII( OR=0.999, P=0.009)were statistically different between the prostate patients and non-prostate cancer patients in the modeling group; Multivariate analysis showed that age( OR=1.094, P<0.001), fPSA( OR=0.605, P=0.002), histological inflammation ( OR=0.241, P<0.001), PSAD ( OR=7.57, P=0.013), PLR ( OR=0.994, P=0.005) and PI-RADS v2.1 Score(3-point OR=2.737, P=0.016; 4-point OR=8.621, P<0.001; 5-point OR=47.65, P<0.001) was an independent influencing factor for prostate cancer at initial biopsy; a nomogram model based on age, fPSA, PSAD, PLR and PI-RADS v2.1 scores was established. The AUC of the modeling group was 0.849(95% CI 0.810-0.888), and the sensitivity was 80.9%, and the specificity was 76.1%; the AUC of the validation group was 0.862(95% CI 0.809-0.915), and the sensitivity was 91.9%, and the specificity was 67.8%, suggesting that the diagnostic prediction model had a good discrimination. The calibration curve showed that the prediction model was well calibrated ( χ2=6.137, P=0.632). The decision curve analysis (DCA) of the modeling and validation groups indicated a larger net benefit of the predictive model. Conclusions:The nomogram model established in this study based on age, fPSA, PSAD, PLR and PI-RADS v2.1 score showed good predictive efficacy for prostate biopsy in patients with PSA between 4-20 ng/ml.
