Abstract
BACKGROUND Pneumoconiosis is an important occupational disease; the association between pneumoconiosis and depression was largely unknown. This study aimed to investigate the relationship between pneumoconiosis and the risk of subsequent depression. METHODS A retrospective cohort study was conducted using Taiwan's National Health Insurance database. The study included 16,795 patients diagnosed with pneumoconiosis between 2008 and 2018 and a comparison cohort of 67,180 individuals without pneumoconiosis, propensity score matched in a 1:4 ratio based on age, sex, monthly income, residential urbanization level, and date of pneumoconiosis diagnosis. The development of depression was monitored until the end of 2019. RESULTS The incidence of depression was 1.68 times higher in the pneumoconiosis cohort than that in the comparison cohort, with an incidence rate of 10.07 versus 5.99 per 1000 person-years (adjusted hazard ratio [aHR] = 1.84, 95 % confidence interval [CI] = 1.70-1.99). The risk of depression increased with an increased mean annual number of emergency department visits for pneumoconiosis, with aHRs of 1.34 (95 % CI = 1.13-1.59) and 2.31 (95 % CI = 1.94-2.76) for 1 ≤ n < 2, and n ≥ 2 compared to n < 1, respectively. LIMITATION The database lacked detailed socioeconomic history, family history, and clinical variables. CONCLUSION This study found that patients with pneumoconiosis have a significantly higher risk of depression than those without pneumoconiosis. Furthermore, the risk of depression increases with the frequency of emergency department visits for pneumoconiosis. Healthcare professionals should pay close attention to the mental health of patients with pneumoconiosis.

Abstract
Rationale: Indigenous populations in the United States face numerous health disparities, but the health of Indigenous workers is less well understood. In a recent surveillance study of active Indigenous coal miners, 3% had coal workers' pneumoconiosis/black lung, and 9% had respiratory impairment. However, occupational lung disease prevalence among Indigenous coal miners has not been directly compared with that among other race/ethnicity groups. Coal miners who are totally disabled from black lung may qualify for U.S. Department of Labor (DOL) compensation benefits, but it is unclear how current federal spirometry criteria affect qualification for Indigenous coal miners.Objectives: To compare findings of pneumoconiosis and respiratory impairment in Indigenous and non-Indigenous coal miners in the western United States and assess federal compensation qualification for Indigenous miners using different spirometry standards.Methods: We used voluntary medical surveillance data from 2002 to 2023 to compare the adjusted odds of pneumoconiosis and respiratory impairment between Indigenous/non-Indigenous coal miners. We examined the proportion of Indigenous miners meeting DOL criteria for federal compensation using different spirometry standards.Results: We identified 691 western U.S. coal miners with at least one year of coal mining employment, 289 Indigenous and 402 non-Indigenous (96% White/Hispanic). Indigenous miners had a greater odds ratio for pneumoconiosis for each additional decade of life (2.47 [95% confidence interval (CI), 1.66-3.68]) compared with non-Indigenous coal miners (1.48 [95% CI, 1.19-1.85]). For each decade, Indigenous coal miners also had a greater adjusted odds ratio for respiratory impairment (1.67 [95% CI, 1.25-2.24]) than non-Indigenous miners (1.06 [95% CI, 0.90-1.25]). Indigenous miners had an additional decline of 71 ml (95% CI, 6-136 ml) in forced expiratory volume in 1 second for each decade of life compared with non-Indigenous coal miners. Using the DOL-mandated Knudson (1976) spirometry standard rather than an Indigenous-specific standard, 6 of 18 (33%) Indigenous miners would not qualify for federal compensation.Conclusions: Indigenous coal miners experience greater adjusted odds for pneumoconiosis and respiratory impairment per decade of life and greater decline in forced expiratory volume in 1 second despite lower smoking rates. Structural inequities exist in federal spirometry requirements for Indigenous miners seeking DOL black lung benefits. Regulatory reform is needed to address barriers to compensation for these underrepresented workers.

Abstract
Objectives To investigate the causal relationships between pneumoconiosis and rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), and gout. Methods The random-effects inverse variance weighted (IVW) approach was utilized to explore the causal effects of the instrumental variables (IVs). Sensitivity analyses using the MR-Egger and weighted median (WM) methods were did to investigate horizontal pleiotropy. A leave-one-out analysis was used to avoid the bias resulting from single-nucleotide polymorphisms (SNPs). Results There was no causal association between pneumoconiosis and SLE, RA or gout in the European population [OR = 1.01, 95% CI: 0.94-1.10, p = 0.74; OR = 1.00, 95% CI: 0.999-1.000, p = 0.50; OR = 1.00, 95% CI: 1.000-1.001, p = 0.55]. Causal relationships were also not found in pneumoconiosis due to asbestos and other mineral fibers and SLE, RA and gout [OR = 1.01, 95% CI: 0.96-1.07, p = 0.66; OR = 1.00, 95% CI: 1.00-1.00, p = 0.68; OR = 1.00, 95% CI: 1.00-1.00, p = 0.20]. Conclusion Our study suggests that pneumoconiosis may have no causal relationship with the three inflammatory immune diseases.

Abstract
BACKGROUND In industries worldwide, crystalline silica is pervasive and poses risks of pneumoconiosis and respiratory malignancies, with the latter being a knowledge gap in disease burden research that this study aims to address. By integrating both diseases, we also seek to provide an in-depth depiction of the silica-attributed disease burden. METHODS Data from the Global Burden of Disease 2019 were extracted to analyze the disease burden due to silica exposure. The trends of age-standardized mortality rate (ASMR) and age-standardized DALY rate (ASDR) from 1990 to 2019, as well as the age-specific number and rate of deaths and disability-adjusted life years (DALYs) in 1990 and 2019, were presented using GraphPad Prism software. The average annual percentage changes (AAPCs) on ASMR and ASDR were calculated using joinpoint regression models. RESULTS The global trends of disease burden due to silica exposure from 1990 to 2019 showed a significant decrease, with AAPCs on ASMR and ASDR of -1.22 (-1.38, -1.06) and - 1.18 (-1.30, -1.05), respectively. Vietnam was an exception with an unprecedented climb in ASMR and ASDR in general over the years. The age-specific deaths and DALYs mainly peaked in the age group 60-64. In comparison to 1990, the number of deaths and DALYs became higher after 45 years old in 2019, while their rates stayed consistently lower in 2019. Males experienced an elevated age-specific burden than females. China's general age-standardized burden of pneumoconiosis and tracheal, bronchus & lung (TBL) cancer ranked at the forefront, along with the highest burden of pneumoconiosis in Chilean males and South African females, as well as the prominent burden of TBL cancer in Turkish males, Thai females, and overall Vietnamese. The age-specific burden of TBL cancer surpassed that of pneumoconiosis, and a delay was presented in the pneumoconiosis pinnacle burden compared to the TBL cancer. Besides, the burden of pneumoconiosis indicated a sluggish growth trend with advancing age. CONCLUSION Our research highlights the cruciality of continuous enhancements in occupational health legislation for countries seriously suffering from industrial silica pollution and the necessity of prioritizing preventive measures for male workers and elderly retirees.

Abstract
Objective: To analyze the changing trend of incidence and prevalence of pneumoconiosis globally, and provide scientific basis for the formulation of health policy. Methods: In June 2022, through the Global Health Data exchange (GHDx) query tool (http: //ghdx.healthdata.org/gbd-results-tool) , the pneumoconiosis incidence and prevalence data was downloaded and organized. Estimated annual percentage change (EAPC) and age-standardized rate (ASR) were used to estimate the trends of pneumoconiosis from 1990 to 2019. EAPC was estimated by linear regression model based on ASR. Results: The overall ASR of the incidence and prevalence of pneumoconiosis decreased from 1990 to 2019, and their EAPCs were-0.85% (95%CI: -1.11%--0.60%) and -0.78% (95%CI: -1.08%--0.49%) . Over the past 30 years, the incidence and prevalence of pneumoconiosis in all SDI areas showed decreasing trends, especially in high SDI areas, their EAPCs were -1.46% (95%CI: -1.76%--1.15%) and -1.99% (95%CI: -2.44%--1.53%) . 110 countries/areas showed increasing trends in age standardized incidence rate (ASIR) , with Iran and Georgia showing the most pronounced upward trend, their EAPCs were 5.32% (95%CI: 4.43%-6.22%) and 4.39% (95%CI: 3.81%-4.97%) . 125 countries/areas showed anincreasing trends in prevalence ASR, with Iran had the fastest rise in prevalence (EAPC=6.40%, 95%CI: 5.33%-7.49%) . Conclusion: Although decreasing trends in the burden of pneumoconiosis are observed globally from 1990 to 2019, but the burden of pneumoconiosis in low-and middle-income countries or regions are still heavy. We need more effective strategies to prevent and reduce the burden of pneumoconiosis.

Abstract
Coal workers' pneumoconiosis (CWP) is one of the most common and severe occupational diseases worldwide. The main risk factor of CWP is exposure to respirable mine dust. Prediction theory was widely applied in the prediction of the epidemic. Here, it was used to identify the characteristics of CWP today and the incidence trends of CWP in the future. Eight thousand nine hundred twenty-eight coal workers from a state-owned coal mine were included during the observation period from 1963 to 2014. In observations, the dust concentration gradually decreased over time, and the incidence of tunnels and mine, transportation, and assistance workers showed an overall downward trend. We choose a better prediction model by comparing the prediction effect of the Auto Regression Integrate Moving Average model and Generalized Autoregressive Conditional Heteroskedasticity model. Compared with the Auto Regression Integrate Moving Average model, the Generalized Autoregressive Conditional Heteroskedasticity model has a better prediction effect. Furthermore, the status quo and future trend of coal miners' CWP are still at a high level.

Abstract
Objective To explore the risk factors for developing chronic pulmonary heart disease in patients with pneumoconiosis. Methods The medical records of pneumoconiosis patients admitted to an occupational disease hospital in Sichuan Province between January 2012 and November 2021 were collected. Kaplan-Meier (K-M) method, or product-limit method, was used to plot the incidence curves of pulmonary heart disease in the pneumoconiosis patients. Cox proportional hazard regression model was used to analyze the influencing factors associated with chronic pulmonary heart disease in patients with pneumoconiosis. Results A total of 885 pneumoconiosis patients were included in this study. The follow-up time was 12 to 115 months and the median follow-up time was 43 months. A total of 138 patients developed chronic pulmonary heart disease and the incidence density of pulmonary heart disease was 38.50/1000 person-years. Multivariate Cox proportional hazard regression analysis showed that the influencing factors of pneumoconiosis inpatients developing chronic pulmonary heart disease included the following, being 50 and older (hazard ratio [HR]=1.85, 95% confidence interval [CI]: 1.25-2.74), stage Ⅲ pneumoconiosis (HR=2.43, 95% CI: 1.48-4.01), resting heart rate≥100 beats/min (HR=2.62, 95% CI: 1.63-4.21), the complication of chronic obstructive pulmonary disease (COPD) (HR=4.52, 95% CI: 2.12-9.63), underweight (HR=2.40, 95% CI: 1.48-3.87), overweight and obesity (HR=0.54, 95% CI: 0.34-0.86), and triacylglycerol (TG) (HR=0.69, 95% CI: 0.49-0.99). Conclusion Old age, stage Ⅲ pneumoconiosis, high resting heart rate, low BMI, and the complication of COPD are risk factors for chronic pulmonary heart disease in pneumoconiosis patients, while overweight and obesity and TG are protective factors. Early identification of the risk factors and the adoption of the corresponding prevention measures are the key to preventing chronic pulmonary heart disease in patients with pneumoconiosis.

Abstract
Objective: Through the bibliometrics analysis and visual analysis of Chinese and English literature related to pneumoconiosis through CiteSpace, to understand the research situation, research trend and hotspots of pneumoconiosis, so as to provide reference for further research. Methods: In August 2022, CNKI (China National Knowledge Infrastructure) data baseand Web of Science core collection database were used as data sources for literature retrieval. Cite Space.5.8.R3c software was used to analyze the cooperation between authors and institutions, keyword co-occurrence analysis, keyword clustering analysis and keyword emergence analysis. Results: A total of 4726 Chinese literature and 2490 English literature related to pneumoconiosis were included; The annual publication volume of Chinese literature shows a fluctuating downward trend, while the annual publication volume of English literature shows a fluctuating upward trend. The Institute of Labor Health and Occupational Disease of the Chinese Academy of Preventive Medical Sciences and the Institute of Occupational Health and Poisoning Control of the Chinese Center for Disease Control and Prevention have the highest publication volume (55 articles) in the institutional cooperation network; The National Institute for Occupational Safety and Health (NIOSH) in the United States has the highest publication volume (153 articles) in the institutional collaboration network. The results of keyword co-occurrence, clustering, and prominence analysis show that Chinese literature focuses more on clinical research on pneumoconiosis, while English literature focuses more on experimental research related to the pathogenesis of pneumoconiosis. Conclusion: In the related field of pneumoconiosis research, the experimental research and clinical research on the pathogenesis are the main research hotspots.

Abstract
Objective: To explore theepidemiological characteristics and analyse the survival of pneumoconiosis in Chengdu from 2011 to 2021, providing scientific evidence for further prevention and control. Methods: In April 2022, the pneumoconiosis report card of Chengdu from 2012 to 2021 and survival data were collected from the China Disease Control and prevention information system and the occupational pneumoconiosis follow-up survey project.The data of the report card was reorganized and analyzed by R4.4.0 software. Chi-square test was used to compare the case composition ratio between groups. The annual trend of the number of new pneumo coniosis cases was analyzed by linear regression model Kaplan-Meier method was used for survival analysis and log-rank test was used for comparison of survival curves between groups. Results: 816 cases of pneumoconiosis were reported in Chengdu from 2011 to 2021, including 522 cases of stage Ⅰ (63.97%, 522/816), 148 cases of stage Ⅱ (18.14%, 148/816) and 146 cases of stage Ⅲ pneumoconiosis (17.89146/816) ; There were 596 cases of silicosis (73.04%, 596/816), 143 cases of coal worker's pneumoconiosis (17.52%, 143/816). New onset pneumoconiosis was mainly male (810 cases, 99.26%). The median age of diagnosis and the 25th and 75th percentile were 63 (51-71) years old, the median length of dust exposure were 12.00 (5.92-28.00) years, and the types of work were mainly rock drillers (24.63%, 201/816), tunneling workers (19.36%, 158/816) and coal miners (13.60%, 111/816). Among 816 cases of new pneumoconiosis, 35 cases were lost to follow-up (4.29%, 35/816), 605 cases survived and 176 cases died. The 5-year survival rate was 78.6% and the 10-year survival rate was 65.8%. Conclusion: The number of pneumoconiosis reported in Chengdu was relatively stable in recent years. The main type of pneumoconiosis was silicosis, which was concentrated in regions, industries and types of work. We should continue to strengthen the prevention and treatment of pneumoconiosis.

Abstract
Objective: To conduct active surveillance of pneumoconiosis in Jiangsu Province in 2019, to understand the status quo of occupational health of dust-exposed workers, timely detect occupational health damage and occupational hazard factors, and provide scientific basis for the prevention and control of pneumoconiosis in the future. Methods: From January to December 2019, counties (cities and districts) with relatively concentrated dust hazard enterprises in Jiangsu Province were selected as monitoring points to carry out active surveillance of pneumoconiosis, and occupational health examination of dust workers (3540 people) in 255 enterprises were carried out, including chest radiographs and lung function examinations. SPSS 26.0 statistical software was used for statistical analysis of the data, and Chi-square test was used to analyze the difference level of the rate between different groups such as gender, age and service. Results: Among the 255 employers, small enterprises accounted for the highest proportion (186 enterprises, 72.94%), private economy accounted for the highest proportion (225 enterprises, 88.24%), and machinery manufacturing industry accounted for the highest proportion (44 enterprises, 17.25%). Among the 3540 workers exposed to dust, 6 suspected occupational diseases (0.17%), 50 occupational contraindications (1.41%), and 1469 other diseases or abnormalities (41.50%) were detected. Among the 3540 workers exposed to dust, 399 (11.27%) had abnormal chest radiography results, and 848 (23.95%) had abnormal lung function indicators. The abnormal detection rate of chest radiographs in males (12.25%, 359/2931) was higher than that in females (6.57%, 40/609), and the abnormal detection rate of lung function in females (32.18%, 196/609) was higher than that in males (22.24%, 652/2931), with statistical significance (P<0.05). The age of the workers exposed to dust ranged from 17 to 75 (41.78±10.39) years old, and the years of service in contact with dust of the workers ranged from 0.08 to 42 (6.72±7.47) years. There were statistically significant differences in the detection rate of abnormal chest radiography and abnormal lung function among different age and seniority workers (P<0.05). The abnormal rates of forced vital capacity (FVC), forced expiratory volume in the first second (FEV(1)) and FEV(1)/FVC were 13.79% (488/3540), 15.28% (541/3540) and 1.86% (66/3540), respectively. There were significant differences in the detection rate of abnormal chest radiography and abnormal lung function among workers exposed to different dust types (P<0.05) . Conclusion: There are few suspected occupational diseases detected by active surveillance of pneumoconiosis in Jiangsu Province in 2019, and there are differences in occupational health examination results among workers with different dust types, ages, genders and dust exposure years.

Abstract
Objective: To analysis the main types and prevalences of complications among pneumoconiosis patients, and to provide scientific basis for the prevention and treatment of pneumoconiosis. Methods: In January 2023, literatures on pneumoconiosis complications published before December 31, 2022 in China National Knowledge Infrastructure (CNKI), Wanfang Database, Chinese Science & Technology Journal Database (VIP), PubMed and Web of Science were systematically searched. Literatures were selected according to inclusion and exclusion criteria, and relevant data were extracted. Quality assessment tool was used to evaluate the quality of the articles for this study. The combined prevalence of complications among pneumoconiosis patients was calculated by R 4.1.1 software. Subgroup analysis was carried out to explore the origin of heterogeneity. Results: Sixty-four eligible articles were selected from 2276 literatures related to pneumoconiosis and its complications. The combined prevalence of complications among pneumoconiosis patients was 21.1% (95% CI: 16.0%-26.3%, I(2)=99.9%). The combined prevalence of chronic obstructive pulmonary disease (COPD) was 26.4% (95%CI: 17.3%-35.6%, I(2)=97.1%), which was the highest among different types of complications among pneumoconiosis patients. Subgroup analyses revealed that the combined prevalence of tuberculosis among pneumoconiosis stage Ⅰ, Ⅱand Ⅲ were 13.8% (95%CI: 10.5%-17.2%, I(2)=99.6%), 18.4% (95% CI: 14.9%-22.0%, I(2)=99.3%) and 37.3% (95% CI: 30.7%-44.0%, I(2)=99.1%), respectively, showing a corresponding increasing tendency (P<0.05). The combined prevalence of tuberculosis among coal worker's pneumoconiosis patients was 12.9% (95% CI: 6.4%-19.3%, I(2)=97.9%), while the combined prevalence of tuberculosis among silicosis patients was 13.9% (95%CI: 10.0%-17.8%, I(2)=96.9%) . Conclusion: The prevalence of pneumoconiosis patients combined with different types of complications is high, and its prevalence increases with the severity of pneumoconiosis.

Abstract
Background Tracheobronchial variations (TBVs) are more common than previously believed due to the increasing use of multi-detector computed tomography (MDCT). This study aimed to assess TBVs in cases of pneumoconiosis, one of the oldest occupational diseases that still poses a threat to public health. Methods This was a descriptive study that involved reviewing chest MDCT images of 34 cases of pneumoconiosis and 34 control cases retrospectively from January 2020 to April 2022. Variations in the trachea, right main bronchus, left main bronchus, lobar and segmental branches of the cases in the patient and control groups were evaluated according to Boyden's nomenclature. Results The frequency of TBV was 32.4% in pneumoconiosis cases. Although the frequency of TBV was higher in the patient group than in the control group, the difference was not statistically significant (p=0.086). Furthermore, there was no significant difference in terms of TBV classification between the patient and control groups (p=0.407). Additionally, the presence of TBV did not affect the distribution of International Labour Organization categories in pneumoconiosis cases (p=0.360). Conclusions Although our study provides initial insights into the occurrence of TBVs in pneumoconiosis cases, further research is needed to clarify the relationship between these variations and the disease.

Abstract
Objective: To understand the epidemiological characteristics of suspected occupational diseases cases, and to track the subsequent diagnosis of suspected cases in Hubei Province from 2020 to 2021, and to provide theoretical basis for the supervision of suspected occupational diseases. Methods: In April 2022, the data of suspected occupational diseases cases and occupational diseases in Hubei Province from 2020 to 2021 were collected by the Occupational Diseases and Health Risk Factors Information Surveillance System. The distribution and diagnosis of suspected occupational diseases cases were analyzed. We investigated undiagnosed suspected occupational diseases by telephone. Results: From 2020 to 2021, a total of 1872 cases of suspected occupational diseases in 6 categories and 18 species were reported in Hubei Province. The top three suspected occupational diseases were suspected occupational noise deafness (36.75%, 688/1872), suspected coal worker's pneumoconiosis (33.07%, 619/1872) and suspected silicosis (20.99%, 393/1872). The diagnosis rate of suspected occupational diseases was 33.60% (629/1872). The rate of confirmed diagnosis was 63.59% (400/629). The diagnosis rate (26.86%, 456/1698) and rate of confirmed diagnosis (55.48%, 253/456) of suspected occupational diseases detected by occupational health examination were the lowest. The diagnosis rate of suspected occupational diseases detected by comprehensive medical institutions and private medical institutions were lower than disease prevention and control institutions and occupational disease prevention center (P<0.05). The main reasons for not entering the diagnostic procedure included that workers were not informed that they were diagnosed as suspected occupational diseases (31.55%, 124/393), workers were unwilling to apply for occupational disease diagnosis (18.56%, 73/393), and some workers planned to apply for diagnosis but had not yet applied (10.69%, 42/393) . Conclusion: Occupational noise deafness, coal worker's pneumoconiosis and silicosis are the main diseases of suspected occupational diseases in Hubei Province. In order to increase the diagnosis rate and confirmed diagnosis rate of suspected occupational diseases, it is suggested to strengthen management and supervision from the aspects of case management, information warning and worker notification.

Abstract
Objective: To analyze the morbidity characteristics of new occupational diseases in Taian City from 2006 to 2021 and provide scientific evidence for local prevention and treatment of occupational diseases. Methods: In March 2022, the data of newly diagnosed occupational diseases in Taian City from 2006 to 2021 were obtained from Information Monitoring System for Occupational Diseases and Health Hazards. A descriptive analysis was performed for the distribution of onset age, working years, types of occupational diseases, region, industries, enterprise scale, enterprise economic type and the epidemic trend of occupational diseases. Results: 1362 cases of occupational diseases in 29 species of 9 categories were reported in Taian City from 2006 to 2021, including 1311 males and 51 females. The M (P(25), P(75)) of onset age and working age were 53 (47, 64) and 24.08 (16.56, 29.25) respectively. The top three categories of occupational diseases were occupational pneumoconiosis and other respiratory diseases (1128 cases, 82.82%), occupational otolaryngology and oral diseases (107 cases, 7.86%), and occupational chemical poisoning (70 cases, 5.14%) in sequence. Coal worker's pneumoconiosis, noise deafness, silicosis, poisoning of manganese and its compounds and cataract were the top five species of occupational diseases, which accounted for 69.60% (948/1362), 7.64% (104/1362), 5.58% (76/1362), 3.38% (46/1362) and 2.94% (40/1362) of the total cases of occupational diseases.There were significant differences among the composition of occupational diseases categories reported annually (P<0.001), but the number of occupational pneumoconiosis and other respiratory diseases was the highest on each year. The number of occupational diseases showed a decreasing trend with the year, and the optimal fitting curve was an growth curve. The number of newly diagnosed occupational diseases was predicted to be 172 cases from 2022 to 2026. Occupational pneumoconiosis and other respiratory diseases was the main disease in 6 counties. The occupational diseases cases were mainly distributed in Feicheng County and Xintai County, with 520 cases and 504 cases respectively, accounting for 75.18% of occupational diseases cases. The coal mining and washing industry had the largest number of occupational diseases cases, accounting for 73.05% of all occupational diseases cases. 91.85% of occupational diseases cases came from large and medium-sized enterprises. The economic type of enterprises with the most occupational diseases was state-owned enterprises, accounting for 74.52% of occupational diseases cases. Conclusion: The predominant occupational diseases in Taian City are occupational pneumoconiosis and other respiratory diseases, occupational otolaryngology and oral diseases, occupational chemical poisoning. And the prevention and control of occupational diseases should be strengthened in key industries such as coal mining and washing industry, key enterprises such as state-owned large and medium-sized enterprises.

Abstract
Exposure to dust from the mining environment has historically resulted in epidemic levels of mortality and morbidity from pneumoconiotic diseases such as silicosis, coal workers' pneumoconiosis (CWP), and asbestosis. Studies have shown that CWP remains a critical issue at collieries across the globe, with some countries facing resurgent patterns of the disease and additional pathologies from long-term exposure. Compliance measures to reduce dust exposure rely primarily on the assumption that all "fine" particles are equally toxic irrespective of source or chemical composition. For several ore types, but more specifically coal, such an assumption is not practical due to the complex and highly variable nature of the material. Additionally, several studies have identified possible mechanisms of pathogenesis from the minerals and deleterious metals in coal. The purpose of this review was to provide a reassessment of the perspectives and strategies used to evaluate the pneumoconiotic potency of coal mine dust. Emphasis is on the physicochemical characteristics of coal mine dust such as mineralogy/mineral chemistry, particle shape, size, specific surface area, and free surface area-all of which have been highlighted as contributing factors to the expression of pro-inflammatory responses in the lung. The review also highlights the potential opportunity for more holistic risk characterisation strategies for coal mine dust, which consider the mineralogical and physicochemical aspects of the dust as variables relevant to the current proposed mechanisms for CWP pathogenesis.

BACKGROUND Pneumoconiosis is a group of occupational lung diseases caused by dust and fiber exposure. This study analyzes Medicare claims to estimate the burden of pneumoconiosis among fee-for-service (FFS; Medicare Parts A and B) Medicare beneficiaries during 1999-2019 in the United States. METHODS Claim and enrollment information from 81 million continuously enrolled FFS Medicare beneficiaries were analyzed. Beneficiaries with any pneumoconiosis and cause-specific pneumoconiosis (e.g., asbestosis, silicosis) were identified using three case definitions (broad, intermediate, and narrow) with varying diagnostic criteria based on claim International Classification of Diseases, Clinical Modification (ICD-CM) diagnosis codes and Healthcare Common Procedure Coding System codes. Results are presented as ranges of values for the three case definitions. RESULTS The 21-year prevalence range for any pneumoconiosis was 345,383-677,361 (412-833 per 100,000 beneficiaries) using the three case definitions. The highest prevalence was among those ≥75 years of age, males, Whites, and North American Natives. Most claims (70.0%-72.5%) included an ICD-CM diagnosis code for asbestosis. The broad pneumoconiosis prevalence rate increased significantly (p < 0.001) during 2002-2009 by 3%-10% annually and declined significantly by 3%-5% annually starting in 2009. The average annual broad incidence rate declined significantly by 7% annually during 2009-2019. CONCLUSIONS Despite the decline in rate for any pneumoconiosis among Medicare beneficiaries, which is primarily attributed to a decline in asbestosis, pneumoconiosis is prevalent among FFS Medicare beneficiaries.

Abstract
Objective: To analyze the influencing factors of lung function in pneumoconiosis patients, and to provide reference for clinical treatment. Methods: From July 2020 to December 2020, a questionnaire survey was conducted on pneumoconiosis patients in the jurisdiction by using the "Guangdong Province Occupational Disease Prevention and Control Institute" questionnaire, and the relevant items of patients were examined. The rate of counting data is expressed, and the measurement data is expressed by mean and standard deviation. Chi-square test was used for comparison between groups, trend chi-square test was used for trend analysis of ordered classified data. Multivariate analysis was carried out with binary logistic regression model. Results: A total of 1409 pneumoconiosis patients were enrolled. The abnormal rate of lung function in pneumoconiosis patients was 68.77%. The results of trend Chi-square test showed that the abnormal rate of lung function increased with the age of exposure to dust in different age groups (Chi Sqnare Trend=64.12、8.49、24.20, P<0.05) . In univariate analysis, there were statistical significance in different dust exposure age, working age, pneumoconiosis stage, complications and occupational pneumoconiosis diseases (P<0.05) . Multiple logistic regression results showed that age of exposure to dust, years of service, stage of pneumoconiosis and complications were the main influencing factors of lung function in pneumoconiosis patients (P<0.05) . Compared with patients aged 0-30 years, patients aged 50-70 years and older had a higher rate of abnormal lung function (OR=2.16, 95%CI: 1.12~4.16; OR=4.82, 95%CI: 2.05~11.35, all P<0.05) ; Compared with patients with 0~20 years of service, patients with 20~30 years of service and more than 30 years of service had a higher rate of abnormal lung function (OR=1.58, 95%CI: 1.10~2.25; OR=1.63, 95%CI: 1.28~2.40, P<0.05) ; Compared with stage Ⅰ patients, Stage Ⅱ and Stage Ⅲ patients had a higher rate of abnormal lung function (OR=1.62, 95%CI: 1.20~2.17; OR=2.23, 95%CI: 1.40~3.55, all P<0.05) ; Compared with patients without comorbidities, patients with comorbidities had a higher rate of abnormal lung function (OR=1.68, 95%CI: 1.20~2.38, P<0.05) . Conclusion: The factors such as age of exposure to dust, working age, stage of pneumoconiosis and complications may be the influencing factors of lung function in pneumoconiosis patients.

Abstract
Background Pneumoconiosis is the most dangerous occupational disease in China. According to unofficial records, nearly million migrant workers were affected by pneumoconiosis in 2011, with the number increasing annually. Among them, a large number of migrant workers suffering from pneumoconiosis were not medically diagnosed. Therefore, fundamental questions remain unanswered: what is the background of workers who receive a diagnosis of pneumoconiosis, and how does pneumoconiosis affect their future and well-being? Methods In this study, we identified and surveyed 1,134 workers with pneumoconiosis in seven selected regions in China with substantially high incidences of pneumoconiosis by using a combination of cluster sampling, convenience sampling, and snowball sampling. We used demographic, medical, and rehabilitation conditions and welfare questionnaires to collect the data. Results The findings highlighted the socioeconomic status of patients with pneumoconiosis. The majority of workers with pneumoconiosis were adult men who had received no higher education, who lived in rural households, and who were employed in mining or manufacturing industries. Among these workers, 52.8% had been exposed to dust at work for more than 10 years, and 53.1% received a diagnosis of stage II or III pneumoconiosis. More than half of the workers (569 workers, 50.2%) did not receive comprehensive, routine treatment; 33.4% (379 workers) visited a doctor when they experienced physical discomfort, and 6.6% (75 workers) never received treatment. Only 156 workers (13.8%) received rehabilitation services, whereas 978 workers (86.2%) never did. The study results also revealed the severe financial difficulties faced by patients with pneumoconiosis. Only 208 workers (18.3%) had access to work-related injury insurance, with the cost of pneumoconiosis treatment being a substantial burden for 668 workers (60.6%). Conclusion In this study, we explored the existing health and welfare problems faced by workers with pneumoconiosis in China and identified the social injustice and health disparities that these workers experience. We also clarified the primary challenges in implementing safety, health, and welfare policies for these workers and those who are exposed to high-risk environments, such as those working in mining.

Abstract
OBJECTIVES It was aimed to determine the factors affecting the development of chronic obstructive pulmonary disease (COPD) in pneumoconiosis cases. METHODS Pneumoconiosis cases were divided into two groups as those with only pneumoconiosis and those with coexistence of pneumoconiosis and COPD. Demographic data, smoking habits, pulmonary function test, radiological findings, and occupational risk factors of the cases were compared. RESULTS Chronic obstructive pulmonary disease was detected in 134 of 465 pneumoconiosis cases (28.8%) included in the study. It was determined that patients who developed COPD were statistically significantly older, had longer exposure duration, had lower forced expiratory volume in 1 second, forced vital capacity, and forced expiratory volume in 1 second/forced vital capacity values, and had more pulmonary symptoms. Chronic obstructive pulmonary disease development was more common in sandblasting workers, dental technicians, and miners than in other occupations. CONCLUSION It has been shown that the risk of developing COPD is high in cases of pneumoconiosis, independent of smoking, especially in certain occupational groups.

Abstract
BACKGROUND A mesothelioma cluster in Biancavilla (Sicily, Italy), drew attention to fluoro-edenite, a fibre classified by International Agency for Research on Cancer as carcinogenic to humans. Significant excesses in mortality and morbidity were observed for respiratory diseases and a significant excess of pneumoconiosis hospitalizations was reported. OBJECTIVE Aim of this study is to assess the characters of the lung damage in Biancavilla residents hospitalized with pneumoconiosis or asbestosis diagnoses. METHODOLOGY Medical records, available radiographs and computed tomography scans were collected. The obtained imaging was reviewed by a panel of three specialists and focused on pleural and parenchymal abnormalities. Cases with an ILO-BIT or ICOERD score equal or greater than 2 were considered positive for a pneumoconiosis-like damage, cases with a score lower than 2 or insufficient quality of imaging were considered inconclusive. If no pneumoconiotic aspects were present the cases were classified as negative. RESULTS Out of 38 cases, diagnostic imaging for 25 cases were found. Ten cases out of 25 showed asbestosis-like features, nine subjects were considered negative. In six patients' results were inconclusive. CONCLUSIONS Asbestosis-like features were substantiated in Biancavilla residents without known occupational exposure to asbestos. Further studies to estimate population respiratory health are required. Experimental studies on the fibrogenic potential of fluoro-edenite are needed.

Abstract
BACKGROUND Mandatory examination requirements for US coal miners newly entering the workforce have been in place since the 1969 Coal Act mandated chest radiographs and were updated to include spirometry with promulgation of the 2014 Mine Safety and Health Administration Dust Rule. Compliance with the mandatory respiratory screening series is described using data from the National Institute for Occupational Safety and Health Coal Workers' Health Surveillance Program (CWHSP). METHODS Among all radiographic and spirometry submissions to the CWHSP during 30 June 1971-15 March 2022, new underground coal miners who began work in the industry after 30 June 1971, and new underground, surface miners and contractors who began work after new regulations were implemented 1 August 2014, were identified and included in analysis. RESULTS Of the 115 093 unique miners who participated in the CWHSP and whose estimated entry into mining occurred during 30 June 1971-15 March 2019, 50 487 (43.9%) received their initial mandatory radiograph, and 15 452 (13.4%) submitted their initial and 3-year mandatory radiographs. Since new regulations were implemented, compliance with initial radiographs appeared to improve (80%) but compliance with 3-year radiographs remained low (11.6%). Compliance with spirometry testing was also low for initial (17.1%) and follow-up screenings (2.7%). CONCLUSIONS The majority of new coal miners eligible for health surveillance did not receive a baseline radiograph or spirometry test through the CWHSP even though coal mine operators are required by law to provide these. Ensuring coal miners' regular participation in health surveillance from early in their careers is an important way to monitor and protect their respiratory health.

Abstract
BACKGROUND Patients with pneumoconiosis have an elevated risk of contracting pulmonary tuberculosis (PTB) and need particular attention. However, extensive population-based studies on the prevalence of PTB in patients with pneumoconiosis have not been reported in China since 1992. This study aimed to investigate the epidemiological characteristics of PTB in patients with pneumoconiosis based on its social determinants and risk factors in China. METHODS Based on the Commission on Social Determinants of Health (CSDH) framework, data were obtained from a questionnaire survey of patients with pneumoconiosis from China's 27 provinces (autonomous regions, municipalities) from December 2017 to June 2021. By chi-square and multivariate logistic regression analyses, the epidemiological characteristics of PTB in the patients were identified based on its prevalence and odds ratio (OR) and associated social determinants and risk factors. The population attributable fractions (PAFs) of significant risk factors were also calculated. RESULTS The prevalence of PTB in patients with pneumoconiosis ( n = 10,137) was 7.5% (95% confidence interval [CI]: 7.0-8.0%). Multivariate logistic regression analysis showed that risk factors included in-hospital exposure to patients with PTB (OR = 3.30, 95% CI: 2.77-3.93), clinically diagnosed cases (OR = 3.25, 95% CI: 2.42-4.34), and northeastern regions (OR = 2.41, 95% CI: 1.76-3.31). In addition, lack of work-related injury insurance (WRII), being born in a rural area, being unemployed, living in western regions, household exposure to patients with PTB, smoking, being underweight, complications of pulmonary bullae or pneumothorax, hospitalization history, and former drinkers among the rural patients were also statistically significant risk factors. Being born in a rural area, lack of WRII and in-hospital exposure to patients with PTB had higher PAFs, which were 13.2% (95% CI: 7.9-18.5%), 12.5% (95% CI: 8.3-16.7%), and 11.6% (95% CI: 8.8-14.3%), respectively. CONCLUSION The prevalence of PTB in pneumoconiosis remains high in China; it is basically in line with the CSDH models and has its characteristics.

Abstract
Long-term inhalation of welding fume at high exposure can cause welder's pneumoconiosis, and metals in welding dust are associated with respiratory dysfunction. This cross-sectional study, which contains 384 Chinese male workers who were or had been working in a container factory, aimed to assess the potential risk of haemal and urinary metal content in welder's pneumoconiosis. Further, we investigated their effects on lung function parameters. Metal content and lung function were measured using inductively coupled plasma-mass spectrometry (ICP-MS) and spirometer, respectively. The concentration and metal content of respirable dust as well as total dust were collected at this container factory. Lung function of cases with welder's pneumoconiosis was significantly worse, as indicated by lower values of FVC, FVC% predicted, FEV1, FEV1% predicted, MEF25% predicted, and MMEF% predicted (p < 0.05). Results of logistic regression models showed that haemal Cr and Zn were risk factors of welder's pneumoconiosis (OR = 4.98, 95%CI: 1.73-21.20, p = 0.009 for Cr; OR = 5.23, 95%CI: 1.56-41.08, p = 0.033 for Zn) after adjusted with age, BMI, working years, welding dust exposure years, and smoking status. Multiple linear regression models showed that several metals (haemal Cd and Pb; urinary Cd and Fe) were significantly associated with different lung function indices in the welder's pneumoconiosis group. Compared to non-welders, welders were exposed to considerably higher levels of respirable dust, total dust, and six kinds of metals (p < 0.05). In conclusion, haemal Cr and Zn are positively related to welder's pneumoconiosis. Meanwhile, Cd and Pb might worsen lung function in welder's pneumoconiosis.

Abstract
BACKGROUND The prevalence of pneumoconiosis among working United States underground coal miners has been increasing for the past two decades, with the highest rates of disease observed among miners in the central Appalachian states of Kentucky, Virginia, and West Virginia. Surveillance for this disease in the United States focuses on working coal miners, who continue to be occupationally exposed to dust. This study examines the radiographic evidence for postexposure progression of pneumoconiosis in a population of former coal miners no longer occupationally exposed to coal mine dust who were seen at a community radiology clinic in eastern Kentucky. METHODS Data were obtained and analyzed from clinical records of former coal miners who had a clinic encounter during January 1, 2017-August 1, 2019, a recorded final year of employment, and ≥2 postemployment digital chest radiographs. Radiographs were classified according to the International Labour Office guidelines by at least two B Readers. A final summary pneumoconiosis severity score (range, 0-13), accounting for both small and large opacities, was assigned to each chest radiograph. Progression was defined as an increase in severity score between a miner's radiographs over time. RESULTS Data for 130 former coal miners were analyzed. All miners were male and most (n = 114, 88%) had worked primarily in Kentucky. Information on race/ethnicity was not available. The most common job types were roof bolters (n = 51, 39%) and continuous miner operators (n = 46, 35%). Forty-one (31.5%) miners had evidence of radiographic disease progression after leaving the workforce, with a median of 3.6 years between first and latest postretirement radiograph. A total of 80 (62%) miners had evidence of pneumoconiosis on their latest radiograph, and two-thirds (n = 53) of these were classified as progressive massive fibrosis (PMF), the most severe form of the disease. CONCLUSIONS Postexposure progression can occur in former coal miners, emphasizing the potential benefits of continued radiographic follow-up postemployment. In addition to participating in disease screening throughout their careers to detect pneumoconiosis early and facilitate intervention, radiographic follow-up of former coal miners can identify new or progressive radiographic findings even after workplace exposure to respirable coal mine dust ends. Identification of progressive pneumoconiosis in former miners has potential implications for clinical management and eligibility for disability compensation.

Abstract
This review provides an overview of literature addressing progressive massive fibrosis (PMF) from September 2009 to the present. Advances are described in understanding its pathophysiology, epidemiology of the occurrence of PMF and related conditions, the impact of PMF on pulmonary function, advances in imaging of PMF, and factors affecting progression of pneumoconiosis in dust-exposed workers to PMF. Basic advances in understanding the etiology of PMF are impeded by the lack of a well-accepted animal model for human PMF. Recent studies evaluating lung tissue samples and epidemiologic investigations support an important role for the silica component of coal mine dust in causing coal workers' pneumoconiosis and PMF in contemporary coal miners in the United States and for silica in causing silicosis and PMF in artificial stone workers throughout the world. Development of PMF is associated with substantial decline in pulmonary function relative to no disease or small opacity pneumoconiosis. In recent reports, computed tomography has had greater sensitivity for detecting PMF than chest x-ray. Magnetic resonance imaging shows promise in differentiating between PMF and lung cancer. Although PMF develops in dust-exposed workers without previously identified small opacity pneumoconiosis, the presence of small opacity pneumoconiosis increases the risk for progression to PMF, as does heavier dust exposure. Recent literature does not document any effective new treatments for PMF and new therapies to prevent and treat PMF are an important need.

Abstract
OBJECTIVE This study aims to summarize the characteristics of diagnosed pneumoconiosis and pneumoconiosis death in the Hubei Province of China, between the years 1949 and 2019, and provide clues for the scientific prevention of pneumoconiosis. METHODS We recruited 23,069 pneumoconiosis cases in Hubei Province, China, from 1949 to 2019. Basic information and occupational surveillance information were obtained from the Hubei Occupational Diseases and Health Risk Factors Information Surveillance System. RESULTS The annually diagnosed pneumoconiosis cases showed an overall increasing trend from 1949 to 2019 in Hubei Province. The major types of pneumoconiosis were coal workers' pneumoconiosis (CWP, 49.91%) and silicosis (43.39%). Pneumoconiosis cases were mainly engaged in mining (75.32%) and manufacturing (12.72%), and were distributed in Huangshi (35.48%), Yichang (16.16%), and Jingzhou (7.97%). CWP (47.50%) and silicosis (44.65%) accounted for most of the deaths. CONCLUSIONS The number of pneumoconiosis cases and deaths in Hubei increased in the period of 1949 to 2019. Silicosis and CWP contributed to the predominant types of pneumoconiosis. Prevention and control measures should continue to be taken to reduce the morbidity and mortality of pneumoconiosis.

Abstract
OBJECTIVES To better understand the characteristics of migrant workers with pneumoconiosis in China, and the factors that contribute to their morbidity. DESIGN A cross-sectional study. SETTING This study was conducted in Shanghai, Nanning and Shenzhen, China, between December 2020 and December 2021. PARTICIPANTS There were 601 questionnaires that were analysed involving 198 migrant workers with pneumoconiosis, 205 workers with pneumoconiosis in state-owned enterprises (SOEs) and 198 other migrant workers with non-pulmonary occupational diseases. OUTCOME MEASURES Epidemiological characteristics of pneumoconiosis among migrant workers were determined. Using logistic regression, we examined the factors related to the morbidity of pneumoconiosis in migrant workers. RESULTS The response rate was 93.27%. In comparison with pneumoconiosis among SOE workers, the number of migrant workers with pneumoconiosis who first encountered dust exposure between the ages of 30 and 44 years and had an accumulated dust exposure of 1-10 years was proportionately greater. Migrant workers who developed pneumoconiosis between 18 and 32 years and those who had stage III pneumoconiosis were proportionately greater (p<0.05). Compared with migrant workers with non-pulmonary occupational diseases, six factors were associated with the morbidity of pneumoconiosis in migrant workers. Risk factors were dust exposure (OR=499.25, 95% CI: 68.33 to 3647.59) and someone smoking in the workplace (OR=5.67, 95% CI: 2.18 to 14.78). Protective factors were regular sleeping hours per night, (OR=0.23, 95% CI: 0.09 to 0.60), excellent ventilation (OR=0.09, 95% CI: 0.01 to 0.65), rules and regulations (OR=0.22, 95% CI: 0.07 to 0.66) and post-departure medical examinations (OR=0.24, 95% CI: 0.09 to 0.63). CONCLUSIONS Compared with SOE workers with pneumoconiosis, migrant workers are exposed to dust at an earlier age, but for shorter duration, display morbidity at an earlier age and have a higher proportion of tertiary pneumoconiosis. They are predominantly male and have inadequate employment stability and medical insurance. Occupational health check-ups and management systems are inadequate.

Abstract
Occupational pneumoconiosis is the most serious work-related disease in China. In this paper, pneumoconiosis stages distribution was obtained to study the stages severity of occupational pneumoconiosis patients in China. A meta-analysis was conducted among screening the published literature on the pneumoconiosis epidemiology in China by Stata 15.0. Moreover, a field survey was conducted on 510 migrant workers suffering from pneumoconiosis in four provinces of China, and the results were analyzed by simple linear analysis and ordinal logistic regression analysis. The stage I, II and III pneumoconiosis accounted for 0.71, 0.21, 0.08, respectively, by the results of meta-analysis. The publication bias of these articles is not obvious based on the Egger's test and funnel plots. There was no significant linear correlation between the distribution of pneumoconiosis stages and the economic status and medical conditions in this study. Migrant workers pneumoconiosis stage I, II and III accounted for 0.14, 0.2, 0.66 respectively, which was significantly correlated with length of work and provinces. In China, migrant workers lack effective occupational health protection so that they have higher occupational health risks than urban workers. Therefore, occupational health protection for migrant workers in the occupational health management system needs to be strengthened.

Abstract
Objective: To analyze the level and trend of occupational pneumoconiosis disease burden in Tianjin from 2010 to 2019, and to provide scientific basis for making prevention and control countermeasures and suggestions. Methods: In June 2021, the data of occupational pneumoconiosis cases in Tianjin from 2010 to 2019 were selected from Follow-up survey of occupational pneumoconiosis patients in Tianjin and occupational "Health Hazardous Surveillance Information System", the subsystem of China Disease Control and Prevention Information System. Disability-adjusted life year (DALY) , years of life lost (YLL) and years lost due to disability (YLD) were used to comprehensively measure the disease burden of occupational pneumoconiosis by region, year, disease type, industry, sex and age; Kruskal-wallis H test was used for univariate analysis of DALY loss in pneumdo-niosis occupational. Results: A total of 43089 person-years of DALY due to pneumoconiosis in Tianjin from 2010 to 2019, of which the YLD accounted for about 2/3 (28277 person-years) , the YLL accounted for about 1/3 (14812 person-years) , and the average DALY was 7.34 person-years. The industrial distribution of pneumoconiosis burden in Tianjin was mainly concentrated in the manufacturing industry accounting for 90.6% of the whole industry. The disease types were mainly concentrated in silicosis, foundry pneumoconiosis, asbestosis and cement pneumoconiosis accounting for 34.4%, 16.9%, 13.3% and 10.5%, and the age distribution was mainly concentrated in the 50~<85 years old age group, accouling for 83.6%. The median DALY of occupational pneumoconiosis patients with different pneumoconiosis stages, disability grades and years of service exposed to dust were statistically significant (P<0.05) . Conclusion: The disease burden of occupational pneumoconiosis in Tianjin was still serious. It is necessary to take targeted intervention measures for key industries and population.

Abstract
Objective: To analyze the change trend of underground dust concentration, the incidence and survival status of pneumoconiosis patients, and provide reference for improving the working environment of dust-exposed workers and the prevention and treatment of pneumoconiosis patients in the future. Methods: In February 2020, a retrospective investigation was conducted on the dust data of underground mining operations in a steel enterprise in Jiangsu Province from 1991 to 2019, and the case data of patients diagnosed with pneumoconiosis from 1956 to 2019 were collected. The time trends of the number of pneumoconiosis patients and dust concentration, the stage of pneumoconiosis and survival status of patients were analyzed. Results: From 1956 to 2019, a total of 241 patients with pneumoconiosis were diagnosed in the steel enterprise. From 1991 to 2019, the annual average dust concentration in the mine showed a downward trend as a whole. Compared with the transportation platform (14.28%, 1447/10132) , the average dust concentration exceeding rate of the mining platform (43.68%, 8415/19263) was significantly higher (χ(2)=2674.84, P<0.01) . The average age of pneumoconiosis patients was (73.54±10.42) years old, and the average working age of dust exposure was (21.41±8.68) years, of which 85 cases (35.27%) survived and 156 cases (64.73%) died. The main type of pneumoconiosis was silicosis (90.46%, 218/241) , and the main stage of pneumoconiosis was the stage I (96.68%, 233/241) ; The higher the stage of pneumoconiosis, the younger the diagnosis age (P<0.01) . The average survival time of patients was (27.264±1.982) years, and the median survival time was 28 years. The cumulative survival rates of patients with pneumoconiosis in different diagnosis time periods were significantly different (χ(2)=35.57, P<0.01) . Conclusion: The improved dust-proof measures have a significant effect on reducing the concentration of underground dust. We need to focus on the dust control of underground mining platforms and the treatment of patients with stage Ⅲ pneumoconiosis.

Abstract
OBJECTIVES The aim of the study was to investigate and assess the incidence of silicosis cases acknowledged as occupational diseases in Poland in 2000-2019. MATERIAL AND METHODS The cases of all medically recognized pneumoconioses, including silicoses, certified as occupational diseases were studied. The records were extracted from the Central Register of Occupational Diseases, the only official Polish central electronic data base of occupational diseases. RESULTS During the period 2000-2019, 2066 confirmed cases of silicoses and 10 665 cases of other pneumoconioses including asbestosis and coal workers' pneumoconiosis were reported to the Central Register of Occupational Diseases. Silicoses accounted for 12.8-21.2% of all pneumoconioses. The number of confirmed silicoses cases was growing along with the length of latency period and was the highest for the period of ≥40 years (513 cases). Over 70% of silicoses cases occurred after occupational exposure >20 years. The most workers who evolved silicosis were employed in manufacturing, predominantly casting of iron, mining and quarrying and construction. CONCLUSIONS The number of confirmed cases of silicosis in Poland decreased in 2000-2019 but the disease still remains an important health problem. Prevention is crucial to reduce further disease incidence. The medical monitoring standards of exposed workers should be improved. Developing new diagnosing guidelines with the use of other imaging examinations, like high-resolution computed tomography, has to be considered. The analysis should contribute into the implementation of silicosis preventative programmes, both at the enterprise and national level. Int J Occup Med Environ Health. 2022;35(5):561-70.

Abstract
OBJECTIVE This study aims to determine the occupational health status of workers exposed to dust and the risk factors of lung function decline, to provide a basis for formulating corresponding occupational disease-prevention strategies. METHODS Data on 2045 workers exposed to dust, including their age, gender, exposure time, chest X-ray test results, and pulmonary function test results, were obtained from a key occupational disease monitoring project in Chongqing, China, in 2021. Chi-square tests and multifactorial logistic regression, and other methods, were used for statistical analysis. RESULTS The prevalence of pneumoconiosis-like changes was 0.83% (17/2045), and the prevalence of abnormal forced expiratory volume in one second (FEV1), forced vital capacity (FVC), and FEV1/FVC was 4.25% (87/2045), 12.81% (262/2045), and 1.47% (30/2045), respectively. With increasing worker's age, the prevalence of abnormal pneumoconiosis-like changes (p = 0.0065), FEV1 (p = 0.0002), FVC (p < 0.0001), and FEV1/FVC (p = 0.0055) all increased. Factors such as age, exposure duration, enterprise size, and dust exposure concentration were associated with abnormal lung function. CONCLUSIONS Workers exposed to occupational dust have a high rate of abnormal lung function. The government, enterprises, and individuals should pay attention to occupational dust exposure, and various effective measures should be actively taken to protect the life and health of workers.

Abstract
Pneumoconiosis is an occupational lung disease with the highest incidence in China. There is no effective treatment drug at present. Animal and cell models are the basis for exploring its pathogenesis and developing effective drugs. In this paper, we sort out the methods of animal models of pneumoconiosis and the different cell models induced by dust in recent years, by analyzing and summarizing the advantages and disadvantages, modeling time, pathology and changes in important indicators of different preparation methods of animal models, as well as different cell models induced by the dust to simulate different pathological models and pathological stages, to provide basis for the application and improvement of pneumoconiosis model.

Abstract
The Institute of Occupational Medicine (IOM) was founded in 1969 by the then UK National Coal Board to complete its nation-wide epidemiological study of lung disease in coal miners, the Pneumoconiosis Field Research. The results quantified risks in the industry and were influential across the world in setting preventive standards. The research, based on epidemiology, was multidisciplinary from the start, and the IOM's broad scientific expertise was applied across many other industries with an increasing focus on environmental measurement and ergonomics. In 1990, as the coal industry declined, IOM became a self-funding research charity with a strong commercial arm. It has expanded its research, often with European collaborators and funding from governments, and has achieved wide recognition. This has most recently been applied during the pandemic in areas of hospital ventilation, personal protection, and viral exposure research, illustrating IOM's ability to respond to new environmental or occupational challenges.

Abstract
Objective: The epidemiological characteristics and trend of occupational pneumoconiosis in Hubei Province from 2011 to 2020 were analyzed to provide a theoretical basis for the development of prevention and control strategies for occupational pneumoconiosis. Methods: In March 2021, the data of newly occupational pneumoconiosis in Hubei Province from 2011 to 2020 were collected by the Occupational Diseases and Health Risk Factors Information Surveillance System. Descriptive statistics were adopted to analyze basic situation, region, industry, type of disease, year of diagnosis, age of onset and dust exposureduration of the cases. Results: From 2011 to 2020, a total of 7203 new cases of occupational pneumoconiosis were reported in Hubei Province, including 7125 (98.92%) men and 78 (1.08%) women. The average age of onset was (54.03±10.12) years old. The average duration of dust exposure was (13.80±9.56) years. The mainly types of pneumoconiosis were coal worker's pneumoconiosis (3593 cases, 49.88%) and silicosis (3301 cases, 45.83%). The cases included 4814 cases (66.83%) of stage Ⅰ pneumoconiosis, 1270 cases (17.63%) of stage Ⅱ and 1119 cases (15.54%) of stage Ⅲ. New cases mainly distributed in Yichang City (1586 cases, 22.02%), Shiyan City (1257 cases, 17.45%), Enshi Tujia and Miao Autonomous Prefecture (1050 cases, 14.58%) and Huangshi City (1009 cases, 14.01%), and occurred most frequently in coal mining and washing industry (3743 cases, 51.96%) and nonmetallic mining industry (582 cases, 8.08%). Pneumoconiosis patients of stage Ⅲ were mainly distributed in small enterprises (401 cases, 50.25%) and domestic enterprises (796 cases, 99.75%) . Conclusion: Coal worker's pneumoconiosis and silicosis accounted for the vast majority pneumoconiosis in Hubei Province. The new cases show obvious regions, industries and type of disease distribution. We should strengthen occupational health supervision in small and domestic enterprises.

Abstract
Objective: To understand the survival status and its influencing factors of occupational pneumoconiosis patients in Shizuishan City, and to analyze the disease burden of occupational pneumoconiosis and its trend, so as to provide scientific basis for formulating comprehensive prevention and treatment measures of occupational pneumoconiosis. Methods: A retrospective survey was conducted during July to December 2020 to explore the survival status of occupational pneumoconiosis patients who had been reported from 1963 to 2020 in Shizuishan City. The Kaplan-Meier method and Life-table method were used for survival analysis, and Cox proportional hazards regression model was used to analyze the influencing factors of survival time. The disability adjusted life years (DALY) was applied to analyze the disease burden of occupational pneumoconiosis and its temporal trend. Results: From 1963 to 2020, a total of 3263 cases of occupational pneumoconiosis were reported in Shizuishan City, of which 1467 died, so that the fatality rate was 44.96%. The median survival time was 26.71 years, average age of death was (70.55±10.92) years old. There were significant differences in the survival rates of occupational pneumoconiosis patients among different types, diagnosis age, exposure time, industry, initial diagnosis stage and whether upgraded (P<0.05) . As the survival time increased, the survival rate of patients decreased gradually. When the survival time was ≥50 years, the cumulative survival rate of patients was 4.20%. Cox regression analysis suggested that the type of pneumoconiosis, industry, diagnosis age, exposure time, initial diagnosis stage and whether upgraded were the influencing factors for the survival time of patients with occupational pneumoconiosis (P<0.05) . The total DALY attributable to occupational pneumoconiosis from 1963 to 2020 in Shizuishan City was 48026.65 person years, of which the years of life lost (YLL) was 15155.39 person years, and the average YLL was 10.33 years/person, and the years lost due to disability (YLD) was 32871.26 person years, and the average YLD was 10.07 years/person. The DALY attributed to coal worker's pneumoconiosis and silicosis were 39408.51 person years and 6565.02 person years, respectively, and they accounted for 82.06% and 13.67% of the total disease burden in Shizuishan City, respectively. The DALY caused by occupational pneumoconiosis in the age group of 40-49 years old and the first diagnosis of stage I occupational pneumoconiosis were higher, which were 20899.71 and 36231.97 person years, respectively. The average YLL and average YLD showed a volatility downtrend over time. Conclusion: The disease burden of occupational pneumoconiosis cannot be ignored in Shizuishan City, and timely targeted measures should be taken for key populations and key industries. It is recommended that life-cycle health management and hierarchical medical should be taken to improve the life quality of patients and prolong their lifes.

Abstract
Objective: To understand the incidence of pneumoconiosis in the non-coal mining industry in Jiangsu Province, and provide reference for the prevention and control of pneumoconiosis in the non-coal mining industry. Methods: The data of 7019 newly diagnosed pneumoconiosis patients in non-coal mining industry in Jiangsu Province from January 1956 to December 2019 were collected through the Jiangsu Province Pneumoconiosis Follow-up Network Report System, including the gender of the pneumoconiosis patients, the name of the employer and the location, the industry classification of the employer, the duration of dust exposure in dust exposure, the name of occupational pneumoconiosis disease, the date of diagnosis of pneumoconiosis, etc. The collected case data of patients with pneumoconiosis were entered into the statistical software, and the characteristics of the patients' diagnosis time, region and industry were analyzed. Results: The number of confirmed pneumoconiosis patients in the non-coal mining industry in Jiangsu Province was mostly in 2007 (395 cases) , concentrated in Wuxi City (40.96%, 2875/7019) and Suzhou City (27.72%, 1946/7019) . The industries to which the patients belonged were mainly non-metallic mining and dressing (60.95%, 4278/7019) , and the most common type of pneumoconiosis was silicosis (96.40%, 6766/7019) . The patients were mainly stageⅠpneumoconiosis (61.33%, 4305/7019) . There were statistically significant differences in the mean age of diagnosis and the average duration of dust exposure among patients with different pneumoconiosis stages (P<0.01) . The differences in the average diagnosis age and the average duration of dust exposure of patients with different types of pneumoconiosis were statistically significant (P<0.05) , the mean age of diagnosis and the average duration of dust exposure of electric welders were the smallest, which were (44.92±7.74) years old and (17.38±10.15) years, respectively. Conclusion: The regional and industry distribution characteristics of new pneumoconiosis patients in the non-coal mining industry in Jiangsu Province are obvious, and attention should be paid to the treatment of pneumoconiosis patients with young diagnosed age and short duration of dust exposure, as well as the personal protection and health protection of front-line workers such as electric welders who are exposed to productive dust in a short period of time.

Abstract
Objective To explore the surgical safety of patients with comorbid non-small cell lung cancer (NSCLC) and pneumoconiosis. Methods In this study, the clinical data of 165 NSCLC patients treated at West China Fourth Hospital, Sichuan University from August 2019 to May 2021 were collected. Among them, 21 patients with comorbid pneumoconiosis were included in the pneumoconiosis group, and the remaining 144 patients were included in the general group. Radical resection for lung cancer was performed in both groups. The perioperative clinical data, including preoperative, intraoperative and postoperative indicators, of the two groups were compared and analyzed. Results There was no perioperative death in either group. The proportions of male patients and patients with smoking history in the pneumoconiosis group were significantly higher than those in the general group ( P<0.05). The body mass index (BMI), pulmonary ventilation function and diffusion function in the pneumoconiosis group were significantly lower than those in the general group ( P<0.05). There was no significant difference in the median operative time and the median volume of intraoperative blood loss between the pneumoconiosis group and the general group. In the pneumoconiosis group, the proportion of advanced tumors (stage Ⅱ/Ⅲ), incidence of postoperative complications, median duration of postoperative intubation, and postoperative length of hospital stay were higher/longer than those of the normal group ( P<0.05). Compared with the general group, the incidences of lymph node calcification, dense pleural adhesion and surgical method alteration (switching from thoracoscopic surgery to open surgery or video-assisted thoracoscopy) were also significantly higher in the pneumoconiosis group ( P<0.05). Univariate analysis showed that age, smoking history, pneumoconiosis, pulmonary ventilation dysfunction, lymph node calcification, dense pleural adhesion and the volume of intraoperative blood loss were the risk factors for postoperative complications. Further multivariate regression analysis demonstrated that smoking history ( OR=1.37, P<0.05), lymph node calcification ( OR=2.36, P<0.05) and pulmonary ventilation dysfunction ( OR=5.21, P<0.05) were independent risk factors for postoperative complications. Conclusion NSCLC patients with comorbid pneumoconiosis face relatively greater risks during the perioperative period when they undergo radical resection for lung cancer. Therefore, the close attention of surgeons and the nursing staff should be raised accordingly.

Methods: In January 2021, based on the data of occupational diseases in Guangzhou reported in the Information Monitoring System of Occupational Diseases and Occupational Health, descriptive epidemiological method was used to analyze the types and characteristics of occupational diseases in Guangzhou from 2010 to 2020. Results: A total of 1341 cases of 38 kinds of occupational diseases in 9 categories were reported in the past 11 years. The incidence of occupational pneumoconiosis, occupational otolaryngology and oral diseases and occupational chemical poisoning ranked the top three, accounting for 38.1% (511/1341) , 30.5% (409/1341) and 16.2% (217/1341) of the total cases respectively. The cases of pneumoconiosis in welders and silicosis accounted for 47.7% (244/511) and 34.4% (176/511) of the cases of occupational pneumoconiosis respectively. The cases of noise deafness accounted for 99.8% (408/409) of occupational otorhinolaryngology oral diseases. Acute occupational chemical poisoning cases accounted for 26.7% (58/217) of the occupational chemical poisoning cases, in which dichloroethane poisoning cases ranked the first, accounting for 79.3% (46/58) . Chronic occupational chemical poisoning cases accounted for 73.3% (159/217) of the occupational poisoning cases, in which benzene and lead poisoning cases ranked the top two, accounting for 79.2% (126/159) and 17.6% (28/159) respectively. Conclusion: Pneumoconiosis, silicosis, noise deafness, benzene poisoning, lead poisoning, dichloroethane poisoning should be supervised and managed as key occupational diseases in Guangzhou.

Abstract
Objective: To analyze the epidemiological characteristics of pneumoconiosis in Qinghai Province from 2011 to 2020, and to provide a basis for the formulation of prevention and control strategy. Methods: In April 2021 , the cases of pneumoconiosis were monitored by the Occupational Disease and Health Hazard Factors Monitoring Information System in Qinghai Province from 2011 to 2020. The distribution of pneumoconiosis, the composition of diseases and the working years exposed to dust were analyzed. Results: All 1026 cases of pneumoconiosis were newly diagnosed in Qinghai Province from 2011 to 2020, silicosis and coal worker pneumoconiosis were the main diseases (78.36% ,804/1026). Stage Ⅰ pneumoconiosis were 484 (47.17%,484/1026) cases. 359 (34.99%,359/1026) cases, 315 (30.70%,315/1026) cases and 252 (24.56%, 252/1026) cases had been diagnosed respectively in Xining City, Haidong City and Haixi Prefecture; 628 (61.21%,628/1026) cases and 418 (40.74%, 418/1026) cases engaged in mining industry and large-sized enterprise, respectively. The working years exposed to dust in silicosis cases were shorter than that in coal worker pneumoconiosis and other pneumoconiosis (P <0.05). Conclusion: The pneumoconiosis area and industry focus in Qinghai Province is obvious. The supervision and adninistration of small and micro scale employers should be strengthened to protect the health rights and interests of workers, especially for the key area and industry.

Abstract
BACKGROUND In 2014, a federal rule reduced occupational exposure limits to coal mine dust and expanded medical surveillance eligibility beyond underground miners to surface and contract coal miners. This expansion may have provided an opportunity for more American Indian and Alaska Native (AI/AN) coal miners to participate in screening, since many surface coal mines are located near AI/AN communities and may employ AI/AN miners. Therefore we sought to better understand the respiratory health of AI/AN coal miners by characterizing prevalence of coal workers' pneumoconiosis (CWP), progressive massive fibrosis (PMF), and abnormal lung function in this population. METHODS Descriptive analysis of 1405 chest radiographs and 627 spirometry test results for AI/AN miners who participated in the Coal Workers' Health Surveillance Program (CWHSP) during 2014-2019 was conducted. RESULTS Most AI/AN miners (0-25+ years of tenure) were western United States residents (82.3%) and active surface miners (76.9%) with no underground tenure. Among miners with at least 10 years of tenure, prevalence of CWP was 3.0%, and of PMF was 0.3%. Lung function abnormalities were seen in 9.0% with primarily restrictive patterns. CONCLUSIONS The prevalence of CWP, PMF, and lung function abnormality among active and former AI/AN coal miners was higher than seen in a larger CWHSP study of active western miners working primarily underground with 10+ years of tenure. Interventions that eliminate or control coal mine dust exposure, identify miners with CWP early, and limit respiratory disease progression and complications remain vital for eliminating the preventable adverse health effects of coal mining. Comprehensive demographic data on the coal mining workforce are needed to improve CWHSP participation assessment.

Abstract
Objective: To detect of gene expression and genotype of the ataxia telangiectasia mutated (ATM) from coal workers' pneumoconiosis (CWP) , It is explored whether CWP is related to ATM gene. Methods: In October 2020, the relevant information of 264 subjects who received physical examination or medical treatment in the Department of occupational diseases of Guiyang public health treatment center from January 2019 to September 2020 was collected. Through the occupational health examination, 67 healthy people with no history of exposure to occupational hazards were selected as the healthy control group; The coal miners with more than 10 years of coal dust exposure history and small shadow in the lung but not up to the diagnostic criteria were the dust exposure control group, a total of 66 people; The patients with the same history of coal dust exposure and confirmed stage I were coal worker's pneumoconiosis stage I group, a total of 131 people. The expression of ATM was detected by QRT PCR. ATM rs189037 and rs1801516 were genotyped by massarray. Results: There was significant difference in the expression of ATM among the groups (P<0.05) ; Compared with the healthy control group, the expression of ATM in the dust exposed control group was significantly increased (P<0.05) . With the occurrence and development of CWP, the GG of rs189037 wild type decreased, the GA of mutant heterozygote and AA of homozygote increased, but the difference was not statistically significant (P>0.05) ; Rs1801516 wild type GG and mutant heterozygote GA had no significant changes (P>0.05) . There were significant differences in age, neutrophils and basophils among rs189037 groups (all P<0.05) . There were no significant differences in blood pressure, eosinophils, lymphocytes, monocytes, smoking and drinking history among rs189037 groups (all P>0.05) . Compared with wild-type GG, the or of mutant heterozygotes and homozygotes increased, but the differences were not statistically significant (P>0.05) . Conclusion: ATM gene may be one of the early activation genes of CWP and rs189037 may be the functional loci which affects gene expression. ATM gene is related to inflammatory response, Neutrophils and basophils have an impact on the development of CWP.

Abstract
Objective: To understand the diagnosis of suspected occupational diseases reported in Guangzhou from 2014 to 2019, so as to provide theoretical basis and technical support for the supervision of suspected occupational disease reports. Methods: By cluster sampling, the suspected occupational disease report card, occupational disease report card and pneumoconiosis report card reported by Guangzhou from January 1, 2014 to December 31, 2019 in the occupational disease and occupational health information monitoring system were collected for matching analysis to understand the diagnosis of suspected occupational disease patients. Results: From 2014 to 2019, a total of 1426 suspected occupational cases in 7 categories and 32 species were reported in Guangzhou. The average number of reported cases per year was about 240. The main diseases of suspected occupational diseases were suspected occupational noise deafness (68.44%, 976/1426) , suspected occupational chronic benzene poisoning (16.48%, 235/1426) , suspected occupational other pneumoconiosis (4.84%, 69/1426) , suspected occupational silicosis (3.23%, 46/1426) and suspected occupational welder pneumoconiosis (1.82%, 26/1426) . The diagnostic rate required to enter the occupational disease diagnostic program is 36.61% (522/1426) , and the diagnostic rate is 59.20% (309/522) . In 2019, the diagnosis rate of suspected occupational diseases was the lowest (23.92%, 61/255) , Huadu District was the lowest (8.33%, 9/108) , suspected occupational pneumoconiosis was the lowest (28.03%, 44/157) , the diagnosis rate of suspected occupational diseases reported by the Centers for Disease control and prevention was the lowest (17.43%, 19/109) , and the diagnosis rate of suspected occupational diseases reported by outpatient treatment was the lowest (22.22%, 2/9) . The suspected occupational diseases reported by institutions outside Guangzhou did not enter the occupational disease diagnosis procedure. Suspected occupational skin diseases, suspected occupational diseases caused by physical factors and suspected occupational tumors were diagnosed, and the diagnosis rate of occupational disease prevention and control institutions was the highest (94.87%, 37/39) . Conclusion: The main types of suspected occupational diseases reported during these six years are noise deafness, chronic benzene poisoning and pneumoconiosis. The overall diagnosis rate and diagnosis rate of suspected occupational diseases are not high. It is suggested to improve the network direct reporting system of suspected occupational diseases and strengthen the follow-up management and supervision of suspected occupational diseases.

Abstract
Objective: In order to find out the prevalence and death of pneumoconiosis in Qingyuan City, to explore the regularity of pneumoconiosis and lay a foundation for the prevention and management of pneumoconiosis. Methods: In August to December 2019, the basic data of pneumoconiosis from 1949 to 2018 were obtained through the monitoring of death causes of residents, occupational disease management system, Guangdong population information system and other means. The reported cases of pneumoconiosis were followed up, and retrospective investigation was conducted to analyze the basic conditions, the length of service exposed to dust, the time of diagnosis, the type of disease, the stage and the combined status of tuberculosis of pneumoconiosis cases. Results: From 1949 to 2018, a total of 466 cases of new pneumoconiosis were reported in Qingyuan City, including 325 cases of death (69.74%) , 114 cases of survival (24.46%) and 27 cases of loss of follow-up (5.80%) . The cases were mainly concentrated in the age group of 40-89 years (80.04%, 373/466) . There were 411 male cases (88.20%) and 7 female cases (1.50%) . The median length of service exposed to dust was 10.7 (6.0, 16.0) years. The diagnosis time of pneumoconiosis cases was mainly from 1949 to 1986 (68.67%, 320/466) , and the death cases were mainly from 1949 to 1986 (82.77%, 269/325) . Silicosis was the main type of pneumoconiosis (398 cases, 85.41%) . 200 cases (42.92%) were diagnosed as stage I pneumoconiosis, 185 cases (39.69%) were stage II pneumoconiosis, 81 cases (17.38%) were stage III pneumoconiosis at the first diagnosis. 102 cases (21.89%) were pneumoconiosis with tuberculosis. The proportion of death and lost follow-up cases diagnosed as stage I pneumoconiosis for the first time was significantly lower than that of survival cases, and the proportion diagnosed as stage II pneumoconiosis and the complication rate of tuberculosis were significantly higher than those of survival cases (χ(2)=15.48, 11.29, 32.73, P<0.001) . Conclusion: Pneumoconiosis in Qingyuan City is mainly silicosis. The number of new cases has been increasing in the past decade, and the prevention and control situation is still severe. The comprehensive prevention and treatment of silica dust should be included in the focus of supervision of government functional departments.

Abstract
Objective: To analyze the security situation of patients with occupational pneumoconiosis in Gansu Province to lay the foundation for strengthening the security measures for patients with pneumoconiosis. Methods: In August 2020, a follow-up survey was conducted on the current patients with occupational pneumoconiosis diagnosed and surviving in Gansu Province from 1949 to 2019, to obtain the information of industrial injury insurance, employer compensation, medical insurance, subsistence allowance and so on, and analyze their distribution characteristics. The proportion of patients enjoying various security, medical insurance reimbursement and subsistence allowances was tested by chi square. Results: Among the current patients with occupational pneumoconiosis in Gansu Province, 72.0% (5335/7410) enjoyed the benefits of work-related injury insurance, 8.2% (609/7410) enjoyed the compensation paid by the employer, 91.5% (6780/7410) had medical insurance, and 2.8% (204/7410) had no guarantee. Among the patients with occupational pneumoconiosis, 374 enjoyed the minimum living allowance, accounting for 5.05% (374/7410) ; the first diagnosis period with a high proportion of minimum living allowance was phase Ⅲ, accounting for 15.14% (43/284) . Conclusion: The proportion of medical insurance outpatient and inpatient reimbursement of occupational pneumoconiosis patients in Gansu Province is still at a low level. It is suggested that relevant departments should introduce relevant security policies for workers without fixed employers to reduce the economic burden of patients.

Abstract
OBJECTIVE We aimed to identify a relation between the level of silica exposure and the associated increase in the risk of radiologic usual interstitial pneumonia (UIP) pattern. METHODS We selected data of 796 individuals with pneumoconiosis who had undergone a chest computed tomography (CT). We estimated the silica exposure by comparing their occupational history with the data silica dust exposure. RESULTS Individuals employed as stonemasons demonstrated a 2.30-fold increase in the risk of developing UIP than coal mine workers (odds ratio [OR], 2.30; 95% confidence interval [CI], 1.04 to 5.07). The high silica exposure group was associated with a 2.23-fold increase in the risk of developing UIP than the low silica exposure group (OR, 2.23; 95% CI, 1.07 to 4.69). CONCLUSIONS This study suggests that silica exposure is associated with an increased risk of developing UIP pattern, highlighting a dose-response relationship.
