[Analysis of the burden of coal worker's pneumoconiosis disease in a mining group].

Objective: To provide scientific basis for the prevention and control of pneumoconiosis and the formulation of relevant policies, this paper discusses the loss of health life and economic loss caused by coal worker's pneumoconiosis in a mining group. Methods: From March to October 2017, 1262 cases of coal worker's pneumoconiosis were diagnosed in a mining group from 1972 to 2013. The direct and indirect economic losses are calculated by the step-by-step model method. Direct economic losses include medical expenses, one-time disability allowance, disability allowance, funeral allowance, one-time work death allowance, living and nursing expenses, food allowance, pension for supporting relatives and transportation expenses, etc. Indirect economic losses includes loss of social productivity, additional training fee for new employees, transportation fee for accompanying family members, loss of social productivity of accompanying family members, loss of production suspension and production reduction, etc. Life table method was used to calculate the loss of social productivity caused by coal worker's pneumoconiosis. Results: All 1262 coal worker's pneumoconiosis patients were male. In the stage of pneumoconiosis, 95.40% (1204/1262) of the first stage of pneumoconiosis and 42.62% (538/1262) of the seventh stage of disability. The age of diagnosis (22.02-71.33) was 47.38 years on average. 1262 coal worker's pneumoconiosis patients caused a total of 9068.54 years of health life loss, of which YLD accounted for 93.56% (8484.69/9068.54) . The loss of YLD (0.06-33.30) years in 1262 coal worker's pneumoconiosis patients was 6.70 years per capita. The total economic loss of 1262 coal workers with pneumoconiosis was 2842185447.70 yuan, with a per capita of 2252127.93 yuan. The direct economic loss accounted for 81.59% (2318990168.46/2842185447.70) , which was 4.42 times of the indirect economic loss. Among the direct economic loss per capita, medical expenses accounted for a large proportion of 50.04% (919510.84/1837551.64) . The per capita indirect economic loss is 414576.29 yuan. The loss of social productivity accounted for 56.18% (232908.95/414576.29) . Conclusion: Coal worker's pneumoconiosis causes heavy economic burden and serious loss of social productivity.

[Consensus of experts on standard items of the cohort construction and quality control of temporomandibular joint diseases (2024)].

Temporomandibular joint (TMJ) diseases are common clinical conditions. The number of patients with TMJ diseases is large, and the etiology, epidemiology, disease spectrum, and treatment of the disease remain controversial and unknown. To understand and master the current situation of the occurrence, development and prevention of TMJ diseases, as well as to identify the patterns in etiology, incidence, drug sensitivity, and prognosis is crucial for alleviating patients'suffering.This will facilitate in-depth medical research, effective disease prevention measures, and the formulation of corresponding health policies. Cohort construction and research has an irreplaceable role in precise disease prevention and significant improvement in diagnosis and treatment levels. Large-scale cohort studies are needed to explore the relationship between potential risk factors and outcomes of TMJ diseases, and to observe disease prognoses through long-term follw-ups. The consensus aimsto establish a standard conceptual frame work for a cohort study on patients with TMJ disease while providing ideas for cohort data standards to this condition. Temporomandibular joint disease cohort data consists of both common data standards applicable to all specific disease cohorts as well as disease-specific data standards. Common data were available for each specific disease cohort. By integrating different cohort research resources, standard problems or study variables can be unified. Long-term follow-up can be performed using consistent definitions and criteria across different projects for better core data collection. It is hoped that this consensus will be facilitate the development cohort studies of TMJ diseases.
