ABSTRACT
Background Occupational stress is an important factor affecting the health of working population, wellness is a topic that has received much attention in recent years, and sleep quality and wellness have a certain impact on occupational stress. Objective To understand the current situation of occupational stress among locomotive engineers in in the Yangtze River Delta, explore the influence of well-being and sleep quality on occupational stress, and provide a theoretical basis for occupational stress intervention among locomotive engineers. Methods Sampling was conducted from October to December 2022 using stratified random sampling. The Chinese version of the Brief Occupational Tension Questionnaire based on the Job Demand-Control Model (JDC model), the World Health Organization 5-item Well-Being Index (WHO-5), and the Pittsburgh Sleep Quality Index (PSQI) scale were used to investigate the occupational stress, well-being, and sleep quality of locomotive engineers. Logistic regression was used to analyze the effects of sleep quality and well-being on occupational stress, and additive and multiplicative interaction models were applied to evaluate the interactive effects of well-being and sleep quality on occupational stress. Results A total of 8243 questionnaires were collected from five locomotive companies, and after excluding unqualified questionnaires, a total of 7976 questionnaires were included in the analysis. The number of locomotive engineers in the Yangtze River Delta reporting positive occupational stress was 4633 (58.09%), the number of low-level well-being was 4949 (62.05%), and the number of poor sleep quality was 4129 (51.77%). The distribution of occupational stress varied by age, length of service, region, technical level, nature of vehicle, education, per capita monthly family income, marital status, smoking, drinking, number of exercise sessions per week, quality of sleep, work shifts, and length of commute (P<0.01). The results of logistic regression showed that a lower level of occupational stress was associated with >11000 yuan per capita monthly household income (OR=0.795, 95%CI: 0.656, 0.964), high level of well-being (OR=0.477, 95%CI: 0.430, 0.528), and good sleep quality (OR=0.588, 95%CI: 0.531, 0.651); a higher level of occupational stress was associated with night shifts: 1 or fewer night shifts (OR=1.707, 95%CI: 1.312, 2.221), 2 to 3 night shifts (OR=2.649, 95%CI: 2.111, 3.325), and 4 or more night shifts (OR=2.804, 95%CI: 2.202, 3.571); a higher level of occupational stress was associated with 60 min or more commuting time (OR=1.353, 95%CI: 1.111, 1.646). Regarding interaction between poor sleep quality and low well-being on occupational stress, the relative excess risk ratio (RERI), attributable risk index (API), and synergy index (SI) were 1.451 (1.059, 1.844), 0.417 (0.327, 0.507), and 2.407 (1.787, 3.241), respectively, and the result of the multiplicative interaction was an OR of 1.546 (95%CI: 1.262, 1.893). Conclusion The prevalence of occupational stress among locomotive engineers in the Yangtze River Delta region is generally at a medium level compared with other industries. Good sleep quality reduces the risk of occupational stress to a greater extent than high well-being, and poor sleep quality and low well-being can interact and further increase the risk of occupational stress.
ABSTRACT
The cross regional loose medical alliance is an important carrier in the current integrated development process of medical services in the Yangtze River Delta region. Smith policy implementation process model was used to analyze the development difficulties of cross regional loose medical alliances from idealized policies, policy implementation institutions, policy target groups, and policy implementation environment. Such medical alliances were formed under the background of integrated development in the Yangtze River Delta, with Shanghai′s tertiary public hospitals as leading units and medical institutions in Jiangsu, Zhejiang, and Anhui provinces as member units. Analysis showed that the policies for such medical alliances development had not yet clearly defined the organizational management mode, operational mechanism, and implementation path, and the corporate governance structure of medical alliance was immature; The policy implementation agencies were relatively lagging behind in the support of special funds and the formulation of related supporting policies; Participation of policy target groups was insufficient and their incentive mechanisms was imperfect; There were problems in the policy implementation environment, namely inconsistent medical and health service regulations and systems in different regions, different health financing capabilities of local governments, insufficient coordination of medical institution management concepts, and a lack of unified standards in information systems. Based on the above difficulties, this study proposed to strengthen the development planning and layout of cross regional loose medical alliances, and improve the corporate governance structure; To strengthen the government′s main responsibility and improving policy implementation capabilities; To improve the internal cooperation and operation mechanism of cross regional loose medical alliances, and enhance the sense of identity of the target group; To optimize the policy implementation environment and implement various support measures, so as to provide references for further promoting the coordinated development of high-quality medical resources in the Yangtze River Delta region.
ABSTRACT
Objective:To compare and analyze the pricing units and prices of traditional Chinese medicine (TCM) medical services in 4 provinces of the Yangtze River Delta, for reference for the integrated development of TCM medical service project setting and price coordination in the Yangtze River Delta region.Methods:The medical service price project specifications published on the official websites of relevant departments in 4 provinces of the Yangtze River Delta (updated to March 2022) were obtained to extract data such as project names and pricing units. The pricing units and prices of TCM medical service projects in each province were compared and analyzed; The Jevons index method was used to analyze comparable project prices.Results:The numbers of TCM medical service projects in Shanghai, Jiangsu, Zhejiang, and Anhui were 113, 146, 117, and 198, respectively. The types of pricing units were 15, 24, 13, and 12, respectively. There were differences in the setting of pricing units, especially in acupuncture and moxibustion, which had more decomposition projects. The average price of overall medical services in the Yangtze River Delta was 9.81 times that of TCM medical services. There were differences in the prices of comparable TCM medical service projects among the four provinces. Based on Anhui province, the inter provincial Jevons index of other categories of TCM medical service projects except for TCM massage were all less than 1.00.Conclusions:There were significant differences in the pricing units and prices of TCM medical service projects in the four provinces of the Yangtze River Delta, with Anhui province having the most significant difference compared to the other three provinces; The overall price of TCM medical service projects was relatively low.
ABSTRACT
Background In recent years, ozone (O3) has gradually become a key air pollutant affecting public health. Studies have been conducted to evaluate O3 pollution-associated disease burden for general population, but there is a lack of research on O3 pollution-associated disease burden of gestational complications. Objective To assess the disease burden of O3 pollution on pregnancy complications in the Yangtze River Delta region and the changes in the disease burden resulting from the improvement of O3 pollution levels. Methods Through Chinese databases such as China National Knowledge Infrastructure (CNKI) and Wanfang, as well as English databases including PubMed and Web of Science, a systematic search was conducted to retrieve epidemiological studies investigating the association between O3 exposure and pregnancy complications from January 1, 2010 to February 28, 2023. Using predetermined inclusion and exclusion criteria, retrieved studies were screened and assessed for heterogeneity using the Higgins I2 statistic. The exposure increment was standardized to 10 µg·m−3, and a meta-analysis was conducted to evaluate the exposure-response relationship. Spatial analysis and environmental health risk assessment were then employed, using O3 monitoring data at national air monitoring stations, population data, and related disease burden parameters in the Yangtze River Delta region, to evaluate changes in the disease burden of pregnancy complications associated with improvements in O3 pollution levels. Results The meta-analysis revealed a significant association between maternal O3 exposure and increased risks of gestational diabetes mellitus (GDM) and hypertensive disorders of pregnancy (HDP), particularly in early pregnancy, and the related odds ratios (OR) and 95% confidence intervals (CI) were 1.028 (1.002, 1.055) and 1.031 (1.023, 1.040), respectively. The cities with higher attribution fractions (AF) of GDM and HDP related to O3 exposure in 2017 and 2020 in the Yangtze River Delta region were Xuzhou, Huaibei, Suzhou (Anhui Province), Changzhou, and Wuxi, with most cities showing a significant decrease in AF in 2020. Except for Hefei, the cases of GDM and HDP attributable to O3 exposure in the remaining cities of the Yangtze River Delta region decreased by 16.31% to 57.41% in 2020 compared to 2017. In addition, except for Hefei, Suqian, Anqing, and Wuxi, the direct medical costs attributed to O3 exposure in the remaining cities decreased by 1.12% to 45.36% in 2020 compared to 2017. Conclusion Exposure to O3 during pregnancy is associated with increased risks of GDM and HDP. There are differences in the disease burden of GDM and HDP related to O3 pollution among cities in the Yangtze River Delta region in 2017 and 2020. In 2020, compared to 2017, the disease burden in most cities is decreased.
ABSTRACT
Health service is an important part of the integrated development of the Yangtze River Delta. Taking the cooperation practice between Shanghai Tenth People′s Hospital and Suzhou Yinshanhu Hospital as an example, this article introduced the multi-agent cooperation mode of the loose medical alliance including the government, urban hospitals and cross provincial grassroots medical institutions. Among them, the local government provided policy, fund guarantee and guidance, the urban hospital exported management ideas, medicine talents and technologies, and the primary hospital conducted dual training by inviting in and going out to achieve double growth. Through the high gap cooperation between tertiary hospital and primary hospital, Yinshanhu hospital had been comprehensively developed. The loose medical alliance with multi subject coordination and cross region could give full play to the advantages of the loose healthcare alliance mode, achieve multi-win, and have reference significance for promoting the regional integration of medical and health services in the Yangtze River Delta.

ABSTRACT
Objective To investigate the current distribution of ticks and predict the suitable habitats of ticks in the Yangtze River Delta urban agglomeration in 2017, so as to provide insights into tick control and management of tick-borne diseases in these areas. Methods All publications pertaining to tick and pathogen distribution in the Yangtze River Delta urban agglomeration were retrieved, and the geographical location of tick distribution was extracted. The effects of 19 climatic factors on the distribution of ticks were examined using the jackknife method, including the mean temperature of the wettest quarter, precipitation of the coldest quarter, mean temperature of the driest quarter, maximum temperature of the warmest month, precipitation of the driest month, minimal temperature of the coldest month, annual precipitation, mean daily temperature range, precipitation seasonality, annual temperature range, temperature seasonality, annual mean temperature, mean temperature of the warmest quarter, precipitation of the wettest quarter, isothermality, mean temperature of the coldest quarter, precipitation of the wettest month, precipitation of the driest quarter and precipitation of the warmest quarter. The distribution of ticks was analyzed in 2020 using the maximum entropy (MaxEnt) model, and the potential suitable habitats of ticks were predicted in 2070 using the MaxEnt model based on climatic data. Results A total of 380 Chinese and English literatures were retrieved, and 148 tick distribution sites were extracted, with 135 sites included in the subsequent analysis. There were 7 genera (Haemaphysalis, Rhipicephalus, Ixodes, Dermacentor, Boophilus, Hyalomma and Amblyomma) and 27 species of ticks detected in the Yangtze River Delta urban agglomeration. The climatic factors affecting the distribution of ticks in the Yangtze River Delta urban agglomeration mainly included the mean temperature of the wettest quarter and the precipitation of the coldest quarter, with 26.1% and 23.6% contributions to tick distributions. The high-, medium- and low-suitable habitats of ticks were 20 337.08, 40 017.38 km2 and 74 931.43 km2 in the Yangtze River Delta urban agglomeration in 2020, respectively. The climate changes led to south expansion of the suitable habitats of ticks in the Yangtze River Delta urban agglomeration in 2070, and the total areas of suitable habitats of ticks was predicted to increase by 18 100 km2. In addition, the high-, medium- and low-suitable habitats of ticks were predicted to increase to 24 317.84, 45 283.02 km2 and 83 766.38 km2 in the Yangtze River Delta urban agglomeration in 2070, respectively. Conclusions Multiple tick species are widespread in the Yangtze River Delta urban agglomeration, and the future climate changes may lead to expansion of tick distribution in these areas.
