RESUMO

Objective: To investigate epidemiological characteristics and influencing factors on dust-exposed working years of pneumoconiosis cases in Yantai. Methods: In January 2020, By Cluster sampling way, Using descriptive statistics to analyze dust-exposed working years of the reported 3307 new cases of pneumoconiosis from 2009 to 2019 in Yantai. Analyzing the variation trends by the chi-square trend test. Analyzing single fator by chi-square test. Using multiple classification Logistic Regression analysis to analyze multiple influencing factors. Results: The dust-exposed working age of pneumoconiosis cases decreased by years (P<0.05) . The starting age of dust exposure of cases increased year by year, while positively correlated with the dust-exposed working age (r=-0.217, P<0.05) . The years of dust exposure, starting age of dust exposure, industry, type of economy and scale of enterprise were main influence factors on the dust-exposed working age of pneumoconiosis cases. Conclusion: We should strengthen the management on prevention and control condition of pneumoconiosis in metal smelting and processing industry and privately-owned, small and micro enterprises, and pay attention to workers starting exposed to dust in the age of ≥28 years old.

RESUMO

Background: Pneumoconiosis has high prevalence of chronic obstructive pulmonary disease (COPD), respiratory morbidity, and mortality. Objective: The aim of the present study was to examine patient characteristics and adherence to inhaled therapy among pneumoconiosis with COPD in a real-world clinical setting. Methods: A cohort of pneumoconiosis patients with COPD prescript with at least one type of long-acting inhaled drug was followed for adherence for 2 years. Demographic and COPD-related characteristics were collected in baseline. Results: In baseline, after adjusting for age, dust exposure duration positively correlated with number of acute exacerbation (AE) frequency in the last year. There were close associations among COPD Assessment Tool (CAT) score, modified Medical Research Council Dyspnea Scale (mMRC) grade, number of AE, and pre-FEV1 value. Of 296 participants originally recruited, 213 participants finished the 2-year follow-up for adherence. 122 (57.28%) were non-adherent to inhaled therapy. The most common reason for non-adherence was "relief of symptoms after short-term controller medication use" (53.28%). Patients who were non-adherent reported higher body mass index (BMI), less AE events in the last year, higher pre-FEV1 value, higher post-FEV1 value and low CAT, mMRC scores compared to adherent in baseline. High pre-FEV1 value (OR = 1.04, CI = 1.018-1.064) and low mMRC scores (OR = 0.406, CI = 0.214-0.771) were risk factors found associated with non-adherence. Conclusion: A majority of pneumoconiosis patients complicated with COPD have suboptimal inhaled therapy adherence. Evidence-based, adherence-enhancing interventions should be targeted on less severe subjects.

RESUMO

Objective: To analyze the application of Chronic Obstructive Pulmonary Disease (COPD) Screening Questionnaire and pulmonary function test in dust-exposed migrant workers. Methods: In May 2019, 149 cases of dust exposed migrant workers were selected as the research subjects through the free clinic in the countryside. COPD Screening Questionnaire and lung function test were carried out to analyze the high-risk groups and the influencing factors of positive pulmonary function test results. Results: Among 149 cases of dust-exposed migrant workers, 107 (71.8%) were positive for questionnaire screening, 73 (49.0%) were positive for pulmonary function test, 75 (50.3%) were diagnosed with coal worker's pneumoconiosis, and 101 (67.8%) were diagnosed with lung function injury. The positive rate of pulmonary function of migrant workers with positive questionnaire screening results was significantly higher than that of those with negative results (P<0.05) . The results of multivariate analysis showed that compared with non-pneumoconiosis, the risk of positive pulmonary function test results was higher in dust-exposed migrant workers with stage Ⅲ pneumoconiosis (OR=16.462, 95%CI: 3.390-79.946; P<0.01) . Compared with non-smoking, the risks of positive pulmonary function test results of dust-exposed migrant workers with smoking index of 11-20 package years and >20 package years were higher (OR=19.814, 95%CI: 3.854-101.883; OR=9.733, 95%CI: 2.310-41.008; P<0.01) . Conclusion: The risk of COPD in dust-exposed migrant workers is high, so we should strengthen the early examination of the high pneumoconiosis stage and smoking population. The screening questionnaire can better screen out the high-risk groups of COPD, and it can be used as a basic screening tool.

RESUMO

Objective: To investigate the influencing factors of pneumoconiosis complicated with tuberculosis in order to provide the scientific evidence for formulating the preventive strategies. Methods: From July 2019 to January 2020, all occupational pneumoconiosis patients reported in Guangzhou from 1958 to 2018 were investigated retrospectively (n=1155) . The basic data (including gender, diagnosis time, diagnosis age, dust exposure duration, period, pneumoconiosis disease type, work type and industry) were obtained from pneumoconiosis case card and network report database. The data of pulmonary tuberculosis were collected from the occupational disease diagnosis files of Guangzhou Occupational Disease Prevention and Control Hospital, and were supplemented by telephone follow-up. The distribution of pneumoconiosis and tuberculosis in Guangzhou was analyzed. Binary logistic regression analysis model was used to analyze the influencing factors of pneumoconiosis complicated with pulmonary tuberculosis. Results: Among the 1155 new cases of pneumoconiosis, 357 cases were pneumoconiosis tuberculosis, and the complication rate of tuberculosis was 30.9%. Year of diagnosis, age of diagnosis, dust exposure duration, pneumoconiosis caused by mineral dust and construction industry were influencing factors for pneumoconiosis complicated with pulmonary tuberculosis (OR=0.948, 1.048, 0.972, 3.112, 2.815, P<0.05) . After the adjustment of gender, diagnosis year, diagnosis age, dust exposure duration and diagnosis period, the risk of pulmonary tuberculosis in rock drilling workers was 1.462 times higher than that in other types of work (P<0.05) . Conclusion: The complication rate of tuberculosis in patients with pneumoconiosis is relatively high. The main influencing factors are the year of diagnosis, age of diagnosis, dust exposure duration, the type of pneumoconiosis and the industry. The importance of occupational health examination and health education on prevention and treatment of tuberculosis should be emphasized among dust-exposed workers and pneumoconiosis patients. People with susceptibility factors are the top priority.

RESUMO

Objective: To investigate the status of infections caused by respiratory pathogens and the patterns of infections caused by pathogens in different seasons, age groups and stages of pneumoconiosis so as to explore the pathogen spectrum of respiratory tract infections in pneumoconiosis patients. Methods: The sputum samples of 376 pneumoconiosis patients admitted to an occupational disease hospital in Chengdu between January, 2017 and October, 2019 were collected. Clinical information of the patients was collected and lab tests were conducted to check for 23 kinds of common respiratory viruses, bacteria and fungi in the sputum. The relationship between seasons, ages, and different stages of pneumoconiosis and the pathogen detection rate was analyzed. Results: In the 376 sputum samples, the detection rates of pathogens, viruses, bacteria and fungi were 42.29% (159/376), 32.98% (124/376), 9.57% (36/376) and 6.12% (23/376), respectively. The six pathogens with the highest detection rates were parainfluenza virus, rhinovirus, influenza virus, Candida albicans, Klebsiella pneumoniae and Candida krousei. The severity of respiratory tract infection did not show significant difference in different seasons, age groups, and pneumoconiosis stages. Conclusion: The pathogen spectrum of respiratory tract infections in patients with pneumoconiosis is complicated and the proportion of viral infection is high. However, the severity of the infection is not associated with age, seasonal, or pneumoconiosis staging differences.

RESUMO

ABSTRACT: Pneumoconiosis refers to a spectrum of pulmonary diseases caused by inhalation of mineral dust, usually as the result of certain occupations. The main pathological features include chronic pulmonary inflammation and progressive pulmonary fibrosis, which can eventually lead to death caused by respiratory and/or heart failure. Pneumoconiosis is widespread globally, seriously threatening global public health. Its high incidence and mortality lie in improper occupational protection, and in the lack of early diagnostic methods and effective treatments. This article reviews the epidemiology, safeguard procedures, diagnosis, and treatment of pneumoconiosis, and summarizes recent research advances and future research prospects.

RESUMO

Objective: To analyze the distribution characteristics of new pneumoconiosis in different industries in Tianjin from 2009 to 2018, in order to provide a theoretical basis for the prevention and treatment of pneumoconiosis. Methods: In November 2019, the data of new pneumoconiosis cases in Tianjin from 2009 to 2018 were collected and classified according to difference industries. The epidemiological characteristics of new pneumoconiosis in different industries were analyzed based on time, type of pneumoconiosis, type of work, age, and working age. Results: A total of 4657 new cases of pneumoconiosis were reported in Tianjin from 2009 to 2018, 4640 cases (99.63%) in the first stage, 13 cases (0.28%) in the second stage, and 4 case (0.09%) in the third stage. The number of new cases increased with time and then decreased. Among them, there were 3482 males (74.77%) and 1175 females (25.23%) . The proportion of women with new pneumoconiosis in the non-metallic mineral products industry was the highest, and the differences were statistically significant (P<0.05) . There are differences in the distribution of new pneumoconiosis species in different industries (χ(2)=4920.11, P<0.05) . Silicosis is mainly distributed in non-metallic mineral products industry, metal smelting and rolling processing industry, petroleum processing coking and nuclear fuel processing industries. Foundry worker's pneumoconiosis is mainly distributed in the general equipment manufacturing industry and special equipment manufacturing industry, and cement pneumoconiosis is mainly distributed in the non-metallic mineral products industry. The types of work are mainly distributed in smelting, casting, raw materials and forming workers, and the sum of the three accounts for 36.46% (1689/4657) . The M (P(25), P(75)) of diagnosis age was 56.0 (50.0, 63.0) years, and the M (P(25), P(75)) of working age was 19.0 (16.0, 26.0) years. The working age of new pneumoconiosis patients in the petroleum processing, coking and nuclear fuel processing industries is 19.0 (16.0, 26.0) years, which is shorter than that of other industries (P<0.05) ; The diagnostic age of the general equipment manufacturing industry is 54.0 (49.0, 59.0) years, which is less than that of other industries (P<0.05) . New pneumoconiosis is mainly distributed in large and medium-sized enterprises. New cases of pneumoconiosis in non-metallic mineral products industry, metal smelting, calendar processing industry and general equipment manufacturing industry are mainly distributed in large and medium-sized enterprises. New cases of pneumoconiosis in the metal products industry, special equipment manufacturing industry and petroleum processing, coking and nuclear fuel processing industries are mainly distributed in large enterprises. Conclusion: The work of preventing and controlling pneumoconiosis in Tianjin has a long way to go. We should implement targeted measures according to the characteristics of pneumoconiosis industry, strengthen the supervision of hazard industries, and effectively control the occurrence of pneumoconiosis.

RESUMO

Occupational lung diseases are caused by workplace inhalation of chemicals, dusts, or fumes. They include asbestosis, silicosis, coal workers' pneumoconiosis (CWP), and occupational asthma. These diseases have nonspecific respiratory symptoms and are only identified if an occupational history is taken. Asbestosis typically is diagnosed 20 to 30 years after peak exposure, often when pleural plaques are noted on chest x-ray (CXR). Asbestosis is associated with an increased cancer risk, which is higher in smokers. Silicosis results from exposure to silica dust from sand, stone, and quartz. It is a fibrotic lung disease with acute, chronic, or accelerated presentations; CXR findings show interstitial fibrosis or nodular opacities. Silicosis increases risk of mycobacterial and fungal infections. In CWP, patients may present with mild symptoms and CXR findings showing small fibrous nodules; progressive massive fibrosis may develop, and there is a risk of mycobacterial and fungal infections. Occupational asthma (OA) can occur de novo from inhaling sensitizers that induce immunoglobulin E-mediated airway reactions, or from inhaling irritants such as smoke, dust, and fumes. OA also can be due to sensitizers/irritants aggravating preexisting asthma. There are no cures for these occupational lung diseases, so prevention, including elimination/control of workplace exposures, and early diagnosis are key.

RESUMO

Objective: The epidemiological characteristics of occupational pneumoconiosis in Gansu Province from 2010 to 2018 were analyzed to provide a theoretical basis for the development of prevention and control strategies for pneumoconiosis in Gansu Province. Methods: In March 2019, the data of newly diagnosed occupational pneumoconiosis in 2010-2018 and the data of occupational pneumoconiosis as of December 31, 2018 in Gansu Province were collected by the Occupational Disease and Occupational Health Information Monitoring System. The stage, type of disease, time, enterprise information of newly diagnosed pneumoconiosis and the region, type of disease, enterprise information of existed pneumoconiosis were analyzed. Results: From 2010 to 2018, a total of 1269 new cases of occupational pneumoconiosis were reported in Gansu Province, including 818 cases (64.46%) of stage I pneumoconiosis, 284 cases (22.38%) of stage II pneumoconiosis, 167 cases (13.16%) of stage III pneumoconiosis. Silicosis, coal worker's pneumoconiosis and cement pneumoconiosis ranks the top 3, accounting for 55.71% (707/1269) , 37.67% (478/1269) and 3.78% (48/1269) of the total number, respectively. The new cases of stage III pneumoconiosis were mainly distributed in private economy (58.09%, 79/136) and small-sized (59.88%, 97/162) enterprises. As of December 31, 2018, Gansu Province had reported a total of 12211 cases of occupational pneumoconiosis, of which 58.16% (7102/12211) were coal worker's pneumoconiosis and 28.15% (3438/12211) were silicosis. Mainly distributed in Baiyin city (21.63%, 2641/12211) , Lanzhou city (17.79%, 2172/12211) and Wuwei city (13.73%, 1676/12211) . The existed cases of pneumoconiosis are mainly distributed in state-owned economy (76.95%, 9396/12211) and large-sized (54.23%, 6622/12211) enterprises. Conclusion: Silicosis and coal worker's pneumoconiosis are the main type of pneumoconiosis in Gansu Province. And the number of silicosis reported is on the rise, which should be taken seriously. Pneumoconiosis in Gansu Province is mainly distributed in state-owned economy and large-sized enterprises. However, pneumoconiosis patients in private economy and small-sized enterprise is generally serious, so it should be the focus of supervision.

RESUMO

Objective: To analyze the situation of hospitalized migrant workers with pneumoconiosis in Hunan Province, and to provide reference for the prevention and treatment of pneumoconiosis. Methods: In July 2019, the data of pneumoconiosis migrant workers hospitalized in Hunan Prevention and Treatment Institute for Occupational Diseases from February 2017 to February 2019 were retrospectively analyzed, and the general situation, region distribution, diagnosis and complications were analyzed. Results: From February 2017 to February 2019, a total of 6344 migrant workers with pneumoconiosis were treated, mainly distributed in Zhuzhou city (1283 cases, 20.22%) , Yiyang city (1048 cases, 16.52%) and Loudi city (783 cases, 12.34%) . Coal worker's pneumoconiosis (4242 cases, 66.87%) and silicosis (2089 cases, 32.93%) were the main types of pneumoconiosis. Among them, 1433 cases (22.59%) were in stage I, 1318 cases (20.77%) were in stage II, and 3593 cases (56.64%) were in stage III. The age of the patients was mainly between 41-60 years old (4584 cases, 72.26%) . 3869 patients (60.99%) had complications and chronic obstructive pulmonary disease (3046 cases, 48.01%) and pulmonary infection (1703 cases, 26.84%) were the most common complications. There were 1510 patients (23.80%) who had two or more complications. There were significant differences in the number of complications among patients with different diagnosis stages and age stages (χ(2)=764.43, 90.24, P<0.01) . Conclusion: Coal worker's pneumoconiosis and silicosis are the main types of pneumoconiosis among hospitalized migrant workers in Hunan Province, and most patients were in stage III. Older patients with higher pneumoconiosis stage have more complications, early diagnosis and treatment should be taken.

RESUMO

Objective: To investigate and understand the general situation and quality of life of migrant workers with pneumoconiosis, and analyze the influencing factors, so as to provide scientific basis for effective countermeasures to improve the quality of life of migrant workers with pneumoconiosis. Methods: In June 2019, 79 cases of migrant workers' pneumoconiosis diagnosed by Shandong Occupational Disease Hospital from March 2017 to August 2018 were selected as the study object by cluster random sampling method. Questionnaires and on-site visits were used to investigate the quality of life and its influencing factors. The questionnaire was administered by self-designed questionnaire and WHO quality of life questionnaire. Results: The farmer's pneumoconiosis patients are generally lower in culture. High school or above is only 6.33% (5/79) . Their economic income is low. The monthly income of less than 1000 RMB is 49.37% (39/79) . The disease was heavy and pneumoconiosis was 58.23% (46/79) . Pneumoconiosis patients without systematic treatment accounted for 69.62% (55/79) . Only 11.39% of rural workers with pneumoconiosis can timely increase or decrease clothing and wear masks to avoid respiratory irritation. Pneumoconiosis patients who smoked accounted for 77.22% (61/79) . The quality of life of the pneumoconiosis patients in the physiological, psychological, social and environmental fields were (10.40±2.31) , (11.40±2.82) , (11.46±3.03) and (8.38±3.37) respectively. The influencing factors of quality of life were pneumoconiosis stage, education level, economic income and smoking (P< 0.05) . Conclusion: The quality of life of migrant workers with pneumoconiosis is generally low. The main factors that affect the quality of life of patients are disease severity (pneumoconiosis stage) , education level, economic income and smoking.

RESUMO

Objective: To analysis the distribution characteristics of coal worker's pneumoconiosis in Hubei Province during 2006-2010 (the 11th Five-Year Plan period) and 2011-2015 (the 12th Five-Year Plan period) , and its correlation with the gross domestic product (GDP) of Hubei Province from 1986 to 2015. Methods: In September 2019, the data of newly diagnosed coal worker's pneumoconiosis reported in Occupational Disease and Occupational Health Information Monitoring System from 2006 to 2015 and the GDP data from 1986 to 2015 in Hubei Province were collected. The distribution characteristics of time, region, enterprise size, industry and economic type of coal-worker's pneumoconiosis and its correlation with GDP were analyzed. Results: In 2006-2015, 3807 new cases of coal worker's pneumoconiosis were reported in Hubei Province. The time distribution generally ascended as a wave trend. The number of new cases reached its peak in 2013 (722 cases) . GDP growth continued between 1986-1995, 1996-2005 and 2006-2015, especially in 2006-2015. New cases of coal worker's pneumoconiosis were mainly distributed in Huangshi city, Yichang city and Enshi prefecture, accounting for 82.40% (3137/3807) of the total cases. The proportion of new cases in Huangshi city was higher than that in Yichang city and Enshi prefecture (χ(2)=272.66, 243.19, P<0.05) . New cases were mainly distributed in coal mining industry (3103 cases, 81.51%) , small-sized and medium (1675 cases, 44.00%) , and private enterprises (1621 cases, 42.58%) . The rank correlation (r(s)) of coal worker's pneumoconiosis in 2006-2015 with GDP in1986-1995, 1996-2005 and 2006-2015 were 0.157, 0.144, 0.200, respectively, and there were no significant differences (P>0.05) . Conclusion: The coalworker's pneumoconiosis in Hubei Province are mostly distributed in small and medium-sized private enterprises, and the regional distribution is concentrated in Huangshi city, Yichang city and Enshi prefecture. The concentration of cases is closely related to the number and energy production of local coal mines. There is no correlation between the growth of GDP and the distribution of cases.

RESUMO

Objective: To study the epidemiological characteristics of occupational diseases in Shenzhen City, China in 2006-2017, and to provide a scientific basis for prevention and control of occupational diseases. Methods: Cases of occupational diseases in 2006-2017 were collected from the Information System of Occupational Diseases and Occupational Health. A statistical analysis was performed to identify the characteristics of the disease distribution in terms of spectrum of disease, year, area, industry, type of economy and enterprise scale. Results: A total of 1673 cases of occupational disease (64 types, 8 classes) were diagnosed and reported in 2006-2017, chemical poisoning (31.50%) , ear, nose and throat diseases (28.21%) , and pneumoconiosis and other respiratory diseases (21.34%) were the most three commonest occupational diseases. The constituent of ratio of ear, nose and throat diseases and occupational diseases caused by physical factors increased in turn, the constituent of chemical poisoning, pneumoconiosis and other respiratory diseases, and skin disease reduced in turn, which all showed the difference was statistically significant (P<0.01) . Occupational diseases were often seen in districts of Baoan, Longgang, Longhua and Pingshan, as well as in private economy and small enterprise, mainly occurred in manufacturing industry. Conclusion: The incidence of occupational diseases increased steadily in 2006-2017, and we need to strengthen common occupational diseases, especially occupational noise-induced hearing loss, pay attention to districts of Baoan, Longgang, Longhua and Pingshan, as well as private economy and small enterprise.

RESUMO

Objective: To analyze the epidemiological characteristics of pneumoconiosis in Hunan Province. Methods: In November 2018, we collected the type of work, pneumoconiosis type, pneumoconiosis stage, length of service, age of onset and complications of pneumoconiosis cases diagnosed by Hunan occupational disease prevention and control hospital from January 2017 to October 2018. A total of 3 325 cases of pneumoconiosis were collected, including 651 cases (19.58%) of occupational pneumoconiosis and 2674 cases (80.42%) of clinically diagnosed pneumoconiosis. The measurement data were expressed by x±s. The comparison between groups was performed by independent sample t test and one-way ANOVA. Results: The age of 651 patients with occupational pneumoconiosis was 35.59-85.15 years old, the average age of onset was (54.27±8.29) years, and the average exposure to dust was (14.74±8.60) years. 2 674 cases of clinically diagnosed pneumoconiosis were 26.85~87.02 years old. The average age of onset was (55.26±7.38) years, and the average exposure time was (18.83±9.35) years. Compared with silicosis patients, coal workers' pneumoconiosis patients had longer exposure time, the difference was statistically significant (P<0.05) , and the difference was statistically significant (F=3.678, P<0.05) . There were no complications in 651 cases of occupational pneumoconiosis. Among 2 674 cases of clinically diagnosed pneumoconiosis, 710 cases (26.55%) had complications.

RESUMO

OBJECTIVES: Occupational dust exposure may induce various lung diseases, including pneumoconiosis and chronic obstructive pulmonary disease (COPD). The features of combined COPD and pneumoconiosis have not been well described, and this may hamper the management. This study aimed to describe the prevalence and characteristics as well as the risk factors of the combined diseases. DESIGN: A cross-sectional study. SETTING AND PARTICIPANTS: 758 patients with pneumoconiosis were recruited at a single-medical centre. Of these, 675 patients with pneumoconiosis, including asbestosis, silicosis, coal workers' pneumoconiosis and other pneumoconiosis, was eligible for analysis. PRIMARY OUTCOME MEASURES: COPD was diagnosed based on clinical features and/or history of exposure to risk factors and post bronchodilator forced expiratory volume in 1 s (FEV1)/forced vital capacity (FVC) ratio <0.7. Clinical data were collected from predesigned medical reports. The patients underwent both chest radiograph and high-resolution CT scans. Risk factors for combined COPD and pneumoconiosis were analysed using regression analysis. RESULTS: COPD prevalence overall was 32.7% (221/675) and was the highest in silicosis (84/221) and coal workers' pneumoconiosis (100/221). COPD prevalence increased with smoking pack-years, dust exposure duration and pneumoconiosis stage. Patients with combined diseases had lower body mass index, higher smoking index and worse pulmonary function. Risk factors for combined diseases included heavy smoking, silica or coal exposure and advanced pneumoconiosis. The interaction between dust exposure and smoking in COPD was also identified. The risk of combined COPD significantly increased with heavy smoking and silica or coal exposure (OR 5.49, 95% CI 3.04 to 9.93, p<0.001). CONCLUSIONS: COPD is highly prevalent in patients with pneumoconiosis, especially patients with silicosis and coal workers' pneumoconiosis. Occupational dust exposure as well as heavy smoking is associated with an increased risk of combined COPD and pneumoconiosis, which demands an effective preventive intervention.

RESUMO

Objective: To investigate the distribution feature of newly diagnosed pneumoconiosis in Guangyuan City from 2007 to 2017 and provide scientific evidence for the prevention and control of pneumoconiosis. Methods: In May 2019, the data of newly diagnosed pneumoconiosis in Guangyuan City during January 2007 to December 2017 were collected from Chinese Information System for Disease Control and Prevention-Occupation Disease and Occupation Health Information Monitoring System. The database was built by Excel 2010. The distribution of period, disease type, region, sex, age, working age, work type and industry were analyzed by SPSS 17.0 software. Results: Totally 3920 new cases of pneumoconiosis were reported in Guangyuan City from 2007 to 2017, 2850 cases (72.70%) were in stage Ⅰ, 724 cases (18.47%) were in stage Ⅱ, and 346 cases (8.83%) were in stage Ⅲ. The main type of pneumoconiosis was coal worker's pneumoconiosis (2544 cases, 64.90%, ) , second was silicosis (1313 cases, 33.49%) . The newly diagnosed pneumoconiosis were mainly distributed in Lizhou area (1855 cases, 47.32%) , Wangcang county (1392 cases, 35.51%) and Cangxi county (509 cases, 12.98%) . The patients were mainly males (3910 cases, 99.74%) , the ratio of males to females was 391∶1. The average diagnostic age was (57.56±17.58) years, the average working age was (13.68±10.81) years. The main types of work were coal miner (1748 cases, 44.59%) , roadheader (1354 cases, 34.54%) and drill man (487 cases, 12.42%) . The industry distribution was mainly mining (2930 cases, 74.74%) . The distribution of enterprise sizes were mainly small and medium-sized (1341 cases, 34.21%) and micro-sized (999 cases, 25.48%) enterprises. Conclusion: The situation of prevention and control of pneumoconiosis in Guangyuan City is still severe and the newly diagnosed cases are dominated by coal worker's pneumoconiosis, mainly concentrated in mining. There are more cases in Lizhou area and Wangcang county. Strengthening the prevention and control of dust hazards in high-risk areas and high-risk groups is the focus of occupational health prevention and control in Guangyuan City.

RESUMO

Objective: To investigate the dose-response relationship between the cumulative dust exposures to anthracite, bituminous coal, and lignite and the cumulative prevalence rates of pneumoconiosis due to the exposures, respectively and provide a basis for scientific development of occupational health standards. Methods: Investigation on the exposure to coal dust and pneumoconiosis prevalence was conducted in 9 state-owned coal mines. The cumulative anthracite, bituminous coal, and lignite dust exposure specific cumulative prevalence rates of pneumoconiosis were calculated by life table method, respectively. The linear regression equations were used to control the unilateral interval to obtain the exposure concentration limits of the respirable coal dust, respectively. Results: A total of 21 000 coal miners in the 9 coal mines were included in the study. The detection rates of pneumoconiosis in coal miners in anthracite, bituminous coal and lignite mines were 11.27%, 21.32%, and 6.00%. The average lengths of exposure to coal dust at pneumoconiosis onset were 20.12 years, 22.88 years, and 25.21 years, respectively and the dose-response relationships between the cumulative respirable coal dust exposure and the cumulative prevalence rates were all linear regression equations, which are y=5.788x-16.043 (R(2)=0.949), y=5.679x-16.837 (R(2)=0.904), and y=6.465x-19.573 (R(2)=0.944), respectively. Supposing that the safety coefficient is 1.2, when the cumulative prevalence rate of pneumoconiosis after 30 years of exposure to dust is not higher than 1%, the exposure concentration limits of the three types of respirable coal dust are 1.7, 2.3, and 3.9 mg/m(3), respectively. Conclusions: The results of this study shows that the detection rate of pneumoconiosis, the average length of exposure to coal dust at pneumoconiosis onset, and the exposure concentration limits of the respirable coal dust varied with coal types. In the case of the same cumulative level of coal dust exposure, the lower the coal volatiles is (i.e. the higher the carbon content is), the higher the cumulative prevalence rate of pneumoconiosis is (anthracite>bituminous coal>lignite). It is suggested to develop national occupational health standards of coal dust exposure according to the grades of coal.

RESUMO

OBJECTIVES: Work-related lung diseases (WRLDs) are entirely preventable. To assess the impact of WRLDs on the US transplant system, we identified adult lung transplant recipients with a WRLD diagnosis specified at the time of transplant to describe demographic, payer and clinical characteristics of these patients and to assess post-transplant survival. METHODS: Using US registry data from 1991 to 2018, we identified lung transplant recipients with WRLDs including coal workers' pneumoconiosis, silicosis, asbestosis, metal pneumoconiosis and berylliosis. RESULTS: The frequency of WRLD-associated transplants has increased over time. Among 230 lung transplants for WRLD, a majority were performed since 2009; 79 were for coal workers' pneumoconiosis and 78 were for silicosis. Patients with coal workers' pneumoconiosis were predominantly from West Virginia (n=31), Kentucky (n=23) or Virginia (n=10). States with the highest number of patients with silicosis transplant were Pennsylvania (n=12) and West Virginia (n=8). Patients with metal pneumoconiosis and asbestosis had the lowest and highest mean age at transplant (48.8 and 62.1 years). Median post-transplant survival was 8.2 years for patients with asbestosis, 6.6 years for coal workers' pneumoconiosis and 7.8 years for silicosis. Risk of death among patients with silicosis, coal workers' pneumoconiosis and asbestosis did not differ when compared with patients with idiopathic pulmonary fibrosis. CONCLUSIONS: Lung transplants for WRLDs are increasingly common, indicating a need for primary prevention and surveillance in high-risk occupations. Collection of patient occupational history by the registry could enhance case identification and inform prevention strategies.
