RESUMEN

Background Tuberculosis is the most common complication of pneumoconiosis, which accelerates the progression of pneumoconiosis. Pneumoconiosis combined with tuberculosis is a major health risk. Objective To understand the outpatient health service utilization for patients of pneumoconiosis combined with tuberculosis and its main influencing factors. Methods A stratified random sampling combined with non-random sampling was used to select 11181 pneumoconiosis patients in 27 provincial administrative regions (excluding Shanghai, Tianjin, Hainan, Tibet Autonomous Region, Taiwan, Hongkong and Macao Special Administrative Regions) from December 2017 to June 2021. A self-constructed questionnaire, i.e. Health Seeking Behaviors of Pneumoconiosis Patients and Their Influencing Factors, was used, which included basic information, outpatient and inpatient service utilization, and influencing factors of medical treatment behaviors of pneumoconiosis patients. The effective recovery rate of the questionnaire was 90.7%. All patients of pneumoconiosis combined with tuberculosis (n=762) were included as the study subjects. The difference of outpatient utilization in the past two weeks, choosing medical institutions, and the reasons of not seeking medical treatment between urban and rural areas, and the influencing factors of outpatient service utilization were analyzed. Results The study subjects were mainly silicosis combined with tuberculosis (502 cases, 65.9%) and coal workers' pneumoconiosis combined with tuberculosis (232 cases, 30.5%), aged (58.6±12.5) years old. The main region was Western China (45.1%), followed by Eastern China (22.1%), Centeral China (20.2%), and Northeastern China (12.6%). The outpatient utilization rate in the past two weeks was 38.5% (293/762), and the main medical institutions consulted were municipal or provincial hospitals (32.0%), district or county hospitals (28.6%), and township hospitals or health service centers (17.5%). Short distance (20.7%), the availability of specialist outpatient services (16.7%), high level of medical care (14.8%), and low medical cost (12.3%) were the main reasons in choosing medical institutions. Higher proportion of patients seeking medical services due to acute exacerbation in rural areas was reported than in urban areas in the past two weeks (P<0.01). In addition to being hospitalized (113 cases, 41.4%) and self-purchasing medicine (46 cases, 16.8%), the reasons for not seeking medical treatment were self-perceived mild symptoms (15.0%) and high medical cost without reimbursement (9.5%). The multiple regression results showed that outpatient rate for patients of pneumoconiosis combined with tuberculosis in the western region was higher than that in the eastern region (OR=1.66, 95%CI: 1.03, 2.68); patients with an annual personal income of 10000-35500 yuan had a higher outpatient rate than the > 35500 yuan income group (OR=2.54, 95%CI: 1.49, 4.36); the outpatient rate of silicosis patients was higher than that of coal workers' pneumoconiosis (OR=1.83, 95%CI: 1.23, 2.72); the outpatient rate of patients with clinically diagnosed cases (no classified stage of pneumoconiosis) was higher than that of patients with stage I pneumoconiosis (OR=2.32, 95%CI: 1.24, 4.31). Exacerbation of pneumoconiosis-related symptoms in past two weeks (OR=4.26, 95%CI: 2.89, 6.28), occupational injury insurance (OR=0.49, 95%CI: 0.30, 0.80), and hospitalization in past one year (OR=2.37, 95%CI: 1.41, 3.97) were the main factors influencing the outpatient health service utilization among patients of pneumoconiosis combined with tuberculosis. Conclusion The outpatient rate of patients of pneumoconiosis combined with tuberculosis is higher than that of patients of pneumoconiosis without tuberculosis. The utilization of outpatient services is related with disease factors and socio-economic security factors.

RESUMEN

Background At present, the practice of pulmonary rehabilitation for pneumoconiosis in China is in a primary stage. The basis for formulating an individualized comprehensive pulmonary rehabilitation plan is still insufficient, which is one of the factors limiting the development of community-level rehabilitation work. Objective To formulate an exercise prescription based on maximum heart rate measured by cardiopulmonary exercise test (CPET), conduct an individualized comprehensive pulmonary rehabilitation program with the exercise prescription for patients with stable pneumoconiosis, and evaluate its role in improving exercise endurance and quality of life, thus provide a basis for the application and promotion of pulmonary rehabilitation. Methods A total of 68 patients were recruited from the Occupational Disease Prevention Hospital of Jinneng Holding Coal Industry Group Co., Ltd. from April to August 2022 , and were divided into an intervention group and a control group by random number table method, with 34 cases in each group. All the pneumoconiosis patients participated in a baseline test. The control group was given routine drug treatment, while the intervention group received multidisciplinary comprehensive pulmonary rehabilitation treatment on the basis of routine drug treatment, including health education, breathing training, exercise training, nutrition guidance, psychological intervention, and sleep management, whose exercise intensity was determined according to the maximum heart rate provided by CPET. The rehabilitation training lasted for 24 weeks. Patients were evaluated at registration and the end of study respectively. CPET was used to measure peak oxygen uptake per kilogram (pVO2/kg), anaerobic threshold (AT), carbon dioxide equivalent of ventilation (EqCO2), maximum metabolic equivalent (METs), and maximum work (Wmax). The modified British Medical Research Council Dyspnea Questionnaire (mMRC), Self-rating Anxiety Scale (SAS), Self-rating Depression Scale (SDS), Pittsburgh Sleep Quality Index (PSQI), Chronic Obstructive Pulmonary Disease Assessment Test (CAT), and Short Form of Health Survey (SF-36) were used to evaluate the potential effect of the comprehensive pulmonary rehabilitation program. Results Among the included 68 patients, 63 patients were having complete data, then 31 cases were assigned in the control group and 32 cases in the interventional group. Before the intervention, there was no significant difference in pVO2/kg, AT, EqCO2, METs, or Wmax between the two groups (P>0.05). At the end of the trail, the indicators like pVO2/kg [(19.81±2.38) mL·(min·kg)−1], AT [(14.48±2.33) mL·(min·kg)−1], METs (5.64±0.69), and Wmax [(85.25±14) W] of patients in the intervention group were all higher than those [(13.90±2.37) mL·(min·kg)−1, (11.70±1.94) mL·(min kg)−1, (3.97±0.70), and (61.77±14.72) W, respectively] in the control group (P<0.001); there was no significant difference in EqCO2 between the two groups (P=0.083). Before the trial, there was no significant difference in mMRC, SAS, SDS, PSQI, or CAT scores between the two groups (P>0.05). At the end of the trail, the mMRC score (1.16±0.57), SAS score (27.93±2.12), SDS score (26.48±1.44), PSQI score (1.08±0.88), and CAT score (4.34±3.28) of patients in the intervention group were lower than those [(2.03±0.83), (35.87±6.91), (34.23±6.65), (5.37±3.03), and (13.87±7.53), respectively] in the control group (P<0.001). The SF-36 scores of bodily pain (94.13±10.72), general health (87.50±5.68), vitality (95.31±5.53), mental health (99.88±0.71), and health changes (74.22±4.42) in the intervention group were higher than those [(71.87±32.72), (65.81±15.55), (74.52±16.45), (86.97±16.56), and (29.84±13.50), respectively] in the control group (P<0.001), and no significant difference was found in social functioning and role emotional scores (P>0.05). Conclusion Comprehensive pulmonary rehabilitation can increase the oxygen intake and exercise endurance of pneumoconiosis patients, ameliorate dyspnea symptoms, elevate psychological state and sleep quality, and improve the quality of life.

RESUMEN

The most important revision of the Consensus of Chinese experts on pneumoconiosis treatment (2024) is to attach importance to antifibrotic treatment, and recommend tetrandrine and nintedanib for the treatment of silicosis and coal worker's pneumoconiosis, especially in patients with rapidly progressing silicosis. The second most important revision is a positive attitude towards lung transplantation which is recommended for patients with end-stage pneumoconiosis who do not respond to medically optimized conservative treatment as early as possible. In addition, new updates also include the addition of the application of metagenomic next-generation sequencing (mNGS) in pneumoconiosis with pulmonary infection, the diagnosis and treatment of pneumoconiosis with nontuberculous mycobacteriosis (NTM), and high-flow nasal cannula oxygen therapy (HFNC) in pneumoconiosis with respiratory failure therapies. The evidence and recommendations of the current version are assessed by the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system.

RESUMEN

@#Pneumoconiosis is the most serious occupational disease in China, and the prevention and treatment of pneumoconiosis attracts extensive social concerns. As a pulmonary interstitial fibrotic disease, pneumoconiosis is featured by disrupted lung tissue structure and impaired lung function. With available evidence on tetrandrine and nintedanib demonstrably retarding the progression of pneumoconiosis fibrosis, antifibrotic treatment of pneumoconiosis, especially rapidly progressive silicosis, should be emphasized. Pneumoconiosis patients could maintain an average level of quality of life and capabilities in social activities through comprehensive health management, early initiation of antifibrotic treatment, active prevention and treatment of pulmonary tuberculosis and other complications and comorbidities, as well as regular rehabilitation treatment and training.

RESUMEN

Objective To understand the epidemiological characteristics of new occupational pneumoconiosis in Zigong City from 2018 to 2022, and to provide the basis for further prevention and treatment of local pneumoconiosis. Methods The information of newly diagnosed and reported cases of pneumoconiosis in Zigong City from 2018 to 2022 was collected through the occupational disease and occupational health information monitoring system, and the characteristics of the distribution of pneumoconiosis in three regions, the composition of diseases and the length of service of exposure to dust were analyzed. Results From 2018 to 2022, the top 3 newly diagnosed pneumoconiosis diseases in Zigong City were silicosis, coal workers' pneumoconiosis and asbestosis. Silicosis cases were mainly distributed in small and medium-sized employers, accounting for 81.41%. Coal workers' pneumoconiosis was mainly distributed in large and medium-sized employers, accounting for 97.24%. Asbestosis mainly distributed in large scale employers, accounting for 96.36%. There was significant difference in dust handling age of different scale employers (H=11.453, P<0.05). The median ages of silicosis, coal workers' pneumoconiosis and other pneumoconiosis were 47.0 years, 52.0 years and 48.2 years, respectively. The median age of dust handling was 3.3 years, 22.0 years and 23.2 years, respectively. The age of onset of coal workers' pneumoconiosis was higher than that of silicosis and other pneumoconiosis (H=72.547, P<0.05), and the age of dust exposure of silicosis was shorter than that of coal workers' pneumoconiosis and other pneumoconiosis (H=10.453, P<0.05). Conclusion The current situation of pneumoconiosis in Zigong City is still severe, with obvious clustering in disease types and industries. Prevention and treatment of pneumoconiosis in key industries should be further strengthened to protect the health rights and interests of workers.

RESUMEN

Background and objective: Silicosis is one of the oldest occupational lung diseases. However, there are very few studies identifying the anthropometric variables associated with silicosis. The present study aimed at studying the association between body surface area (BSA), pulmonary function indices, and 6-minute walk distance (6MWD) in patients with silicosis. Materials and methods: The study was conducted on 102 male patients of silicosis. Height and weight were measured to calculate BSA. Spirometry and 6 minute-walk tests were performed. Data were analyzed using EPI info V 7 software. Student's t-test of significance (ANOVA) was applied to test the difference between means. Results: There are no significant changes found in the 6-minute walk distance with years of exposure and BSA. Statistically significant lower values of pulmonary function indices were observed in patients with BSA <1.6 sq m. Statistically significant higher values of forced expiratory volume in the first second and forced vital capacity were observed in patients with BSA >1.9 sq m in all categories of exposure. Conclusion: In conclusion, patients of silicosis with >1.9 sq m BSA had higher values of pulmonary function indices. Large body size may be of value in protection from developing occupational lung disease.

RESUMEN

La silicosis pulmonar es una enfermedad ocupacional que continúa ocasionando morbilidad en el mundo. Debido a que el sílice es el mineral más abundante en la tierra y en las rocas, son numerosas las fuentes de exposición laboral a la inhalación del polvo de sílice en varios sectores industriales. Por su parte, la silicoproteinosis pulmonar es una forma aguda muy rara de silicosis, que puede desarrollarse con un período de latencia más corto en comparación con la silicosis, luego de la primera exposición al sílice, y se caracteriza por un rápido deterioro de la función pulmonar, sin respuesta efectiva a ningún tratamiento. Por su forma de presentación tan atípica, reportamos el caso de un hombre de 58 años, con antecedente laboral de trabajo en mina de extracción de oro en socavón


Pulmonary silicosis is an occupational disease that continues to cause morbidity in the world. Because silica is the most abundant mineral in soil and rock, sources of occupational exposure to inhalation of silica dust are numerous in various industrial sectors. Alternately, pulmonary silicoproteinosis is a very rare acute form of silicosis, which can develop with a shorter latency period compared to silicosis after the first exposure to silica, and is characterized by a rapid deterioration of lung function, without effective response to any treatment. Due to its atypical form of presentation, we report the case of a 58-year-old man, with a history of working in a gold mine

RESUMEN

Objective To analyze the survival status, distribution characteristics and social security of newly diagnosed occupational pneumoconiosis patients in Guizhou Province from 2006 to 2021. Methods The newly diagnosed pneumoconiosis cases reported in Guizhou Province from 2006 to 2021 were collected from the “Occupational Diseases and Hazards Monitoring Information System” under “National Health Insurance Disease Prevention and Control Information System”. Telephone or face-to-face surveys were conducted to investigate these patients. Results A total of 12 413 newly diagnosed pneumoconiosis patients were reported in Guizhou Province from 2006 to 2021, with 11 192 cases included in the follow-up, and 10 631 cases were followed-up successfully. According to the follow-up study, 10 565 cases (accounting for 99.4%) were survived, and 66 cases (accounting for 0.6%) died. The number of pneumoconiosis showed an increasing trend followed by a sharp decline from 2006 to 2021, reaching its peak in 2016. The main industry of the newly pneumoconiosis cases was concentrated in the mining industry (accounting for 90.6%). The top three regions with surviving cases in the follow-up were Bijie City, Zunyi City, and Qiannan Prefecture, accounting for 34.0%, 25.4% and 12.0%, respectively. The main types of pneumoconiosis were coal workers' pneumoconiosis and silicosis, accounting for 67.1% and 30.8%, respectively. Most cases were in the age group of 50 to <60 years old, accounting for 59.1%, and the majority of the workers had worked in dusty environments for 5 to <25 years, accounting for 91.5%. In terms of social security, about 89.5% of cases were in the basic medical insurance for urban and rural residents which was the most popular social security. The employer's compensation rate was 67.7%, and the work-related injury insurance participation rate was 51.5%. Conclusion Pneumoconiosis cases in Guizhou Province exhibit significant regional disparities. It has a high concentration in the industry, a younger age profile, and limited social security coverage. It is necessary to strengthen the special management of dust and industry supervision in mining industry, intensify follow-up work for pneumoconiosis cases, reinforce the construction of pneumoconiosis rehabilitation station in key regions, and improve the quality of life of pneumoconiosis cases.

RESUMEN

Objective To analyze the distribution, survival conditions, and medical support of newly diagnosed occupational pneumoconiosis (hereinafter referred to as pneumoconiosis) patients in Zhangdian District, Zibo City. Methods A total of 1 189 newly diagnosed pneumoconiosis patients in Zhangdian District from 1956 to 2019 were selected as the study subjects using retrospective method. Data of their age of onset, years of occupational exposure, category of working industry, type of pneumoconiosis, and status of medical support was collected and analyzed. Results The median and the 25th-75th percentiles [M (P25, P75)] of the age of onset were 51.8 (45.5, 56.1) years, and the mortality was 37.0%. The majority of pneumoconiosis cases were silicosis (45.2%) and coal workers' pneumoconiosis (39.8%). The highest prevalence of pneumoconiosis was in the coal mining and washing industry (42.4%), followed by manufacturing (33.4%). Pneumoconiosis patients in stage Ⅰ,Ⅱ, and Ⅲ accounted for 89.1%, 8.7%, and 2.2%, respectively. The M (P25, P75) of the length of work exposed to dust were 24.1 (16.5, 29.9) years.The higher stage of pneumoconiosis the shorter of the length of work exposed to dust among these pneumoconiosis patients(all P<0.05). The overall survival rate, the 5-year survival rate and the 10-year survival rate of these pneumoconiosis patients were 63.0%, 92.3% and 85.9%, respectively. Among the 749 surviving cases, 60.8% were aged 60.0 to <80.0 years. In terms of social security, 100.0% surviving cases enjoyed basic medical insurance, meanwhile, 96.1% and 81.8% patients were covered by major medical insurances and occupational injury insurances, respectively. The M (P25, P75) of age at death were 73.1 (64.0, 77.1) years. The main causes of death were respiratory diseases (59.3%) and malignant tumors (20.4%). Conclusion The prevalent types of pneumoconiosis in Zhangdian District, Zibo City, are coal workers' pneumoconiosis and silicosis. Medical support and assistance are relatively limited. The pneumoconiosis prevention and control focus should be on silicosis and coal workers' pneumoconiosis, particularly in the manufacturing industry.

RESUMEN

Objective To understand the health-related quality of life (HRQOL) of migrant workers with pneumoconiosis who received basic medical treatment in Hunan Province. Methods A total of 613 migrant workers with pneumoconiosis who received basic medical treatment and assistance in Hunan Province was selected as the study subjects using stratified random sampling method. The European Quality of Life-5 Dimensions (EQ-5D) questionnaire was used to assess their HRQOL. Results The abnormality of the five dimensions of the EQ-5D health description system, from high to low, were as follows: daily activities, mobility, pain/discomfort, anxiety/depression, and self-care, with the abnormal rates of 50.9%, 46.8%, 41.1%, 21.0%, and 14.5%, respectively. The visual analogue scale (VAS) score of EQ-5D was (63.5±18.6) points. Patients with stage Ⅲ pneumoconiosis had high abnormality in mobility, daily activities, and pain/discomfort compared with those with stage Ⅰ and Ⅱ disease (all P<0.02). Patients in stage Ⅱ and Ⅲ of pneumoconiosis had higher incidence of anxiety/depression compared with those with stage I disease (all P<0.02). Patients with complications in addition to pneumoconiosis had higher abnormality in mobility, self-care, and pain/discomfort compared to those with simple pneumoconiosis or those eligible for lung lavage treatment (all P<0.02). Patients with simple pneumoconiosis had a higher incidence of anxiety/depression compared with those eligible for lung lavage treatment (P<0.02). Patients with stage Ⅲ pneumoconiosis had lower average VAS scores compared with stage Ⅰ and Ⅱ patients (all P<0.02). Patients with simple pneumoconiosis or those with complications had lower average VAS scores compared with those eligible for lung lavage treatment (all P<0.05). Conclusion The HRQOL of pneumoconiosis patients among migrant workers needs improvement, especially for patients with stage Ⅲ disease and those with complications. This study indicates the need of optimizing policies, raising the hospitalization expense limit for critically ill patients with stage Ⅲ pneumoconiosis or with complications, and improving their HRQOL.

RESUMEN

Objective: To investigate the epidemiological characteristics of pneumoconiosis deaths in Putuo District of Shanghai, and to provide evidence for prevention and management of pneumoconiosis in the future. Methods: In June 2021, the data of 263 patients with pneumoconiosis who died from January 1961 to December 2020 in Putuo District of Shanghai were retrospectively analyzed. Trend χ(2) test, analysis of variance and Spearman rank correlation methods were used to analyze the basic information, age of exposure to dust, promotion period, course of disease and direct cause of death of patients with pneumoconiosis. Results: Among the 263 cases of pneumoconiosis patients who died in Putuo District of Shanghai from 1961 to 2020, 260 cases (98.86%) were male. The main types of pneumoconiosis were foundry worker pneumoconiosis (53.23%, 140/263) and silicosis (43.73%, 115/263). The main types of pneumoconiosis were sand cleaner (36.50%, 96/263). The age of onset was (53.42±10.13) years old, the age of death was (76.14±9.12) years old, and the age of exposure to dust was (20.91±8.99) years. The duration of dust exposure was negatively correlated with the duration of disease (r(s)=-0.24, P<0.001). With the increase of pneumoconiosis stage, the mortality of silicosis and foundry worker pneumoconiosis also showed an increasing trend (χ(2)(trend)=4.22, 3.87, P=0.040, 0.049). 31.94% (84/263) of pneumoconiosis patients died directly from pneumoconiosis, ranking first among the direct causes of death. Conclusion: The death cases of pneumoconiosis in Putuo District of Shanghai are mainly foundry worker pneumoconiosis and silicosis, and pneumoconiosis is the main cause of death.

RESUMEN

Objective: To analyze the clinical diagnostic characteristics of pneumoconiosis patients of migrant workers in Hunan Province, and to provide scientific basis for the prevention and treatment of pneumoconiosis. Methods: In February 2022, through the Hunan Provincial Medical Treatment and Assistance Information Platform for Pneumoconiosis Migrant Workers, the cases of irresponsible subjects with pneumoconiosis that were first diagnosed clinically in Hunan Province from January 2017 to December 2021 were collected, and analyzed their gender, age, length of service, types of pneumoconiosis, stages of pneumoconiosis, and comorbidities. Results: From January 2017 to December 2021, there were a total of 26131 cases of irresponsible pneumoconiosis patients diagnosed clinically in Hunan Province, with males accounting for 99.8% (26072 cases) and an average age of (60.66±8.04) years old. Among the 26131 patients, coal workers' pneumoconiosis and silicosis were the main causes, with 16816 and 9078 cases respectively, accounting for 99.1% of the diagnosed cases. There were 8640 cases (33.1%) of stageⅠpneumoconiosis, 6601 cases (25.2%) of stage Ⅱ pneumoconiosis, and 10890 cases (41.7%) of stage Ⅲ pneumoconiosis. 2051 patients experienced complications. The average age of exposure to dust of 26131 patients was (17.81±9.69) years, and the age of exposure to dust in silicosis patients was (14.60±9.62) years. The working age of coal worker's pneumoconiosis was (19.60±9.26) years. Compared with coal workers' pneumoconiosis patients, silicosis patients had a shorter working time exposed to dust, and the difference was statistically significant (P<0.05) . Conclusion: Coal workers' pneumoconiosis and silicosis are mainly diagnosed for the first time in migrant workers' pneumoconiosis patients in Hunan Province. Pneumoconiosis patients should be diagnosed in time, which is conducive to treatment and rehabilitation.

Objective: To investigate and understand the medical security and quality of life of migrant workers with pneumoconiosis, so as to provide scientific basis for the prevention and control countermeasures of migrant workers with pneumoconiosis and targeted poverty alleviation. Methods: Using a stratified random sampling method, 200 migrant workers diagnosed with pneumoconiosis at the Shandong Academy of Occupational Health and Occupational Medicine from January 2016 to December 2021 were selected as the observation group, while 200 non migrant workers diagnosed with pneumoconiosis were selected as the control group. St. George's Respiratory Questionnaire (SGRQ) and Pneumoconiosis Questionnaire were used to collect and compare information on the age, working age of dust exposure, economic sources, employment status, income, medical security and quality of life of two groups of patients. Results: The age of migrant worker pneumoconiosis patients in the observation group was (58.1±8.1) years old, and the working age of dust exposure was (19.3±10.1) years. The main source of income was children support (85.5%, 171/200), employment status was mainly wait for employment or unemployed (69.0%, 138/200), personal monthly income was mainly non income (90.0%, 180/200), and family annual income was mainly less than 10000 yuan (48.0%, 96/200). The average personal annual medical expenditure of 5000-<10000 yuan accounted for 42.0% (84/200). The age of pneumoconiosis patients in the control group was (59.2±8.9) years old, and the working age of dust exposure was (20.2±10.5) years. The main source of income was retirement pension or salary (99.0%, 198/200), with retirement as the main employment status (66.0%, 132/200), the main personal monthly income was 2000-<4000 yuan (61.5%, 123/200), the main family annual income was 20000-<40000 yuan (44.0%, 88/200), and the average personal annual medical expenditure was mostly non-expenditure (92.0%, 184/200). There were statistically significant differences in the distribution of economic sources, employment status, personal monthly income, family annual income and average personal annual medical expenditure between the two groups (P<0.001). The main type of insurance for the observation group was rural cooperative medical care (68.5%, 137/200), and 87.0% (174/200) had no medical reimbursement and a proportion less than 50%. There were statistically significant differences in insurance type and medical reimbursement proportion between the two groups (P<0.001). The respiratory symptoms, activity ability, daily life influence and total quality of life scores of pneumoconiosis patients in the observation group were significantly higher than those in the control group, the differences were statistically significant (P<0.001) . Conclusion: Migrant workers with pneumoconiosis have low income, high medical expenditure, low medical reimbursement proportion and poor quality of life. Therefore, it is necessary to draw high attention from relevant departments and provide timely attention and assistance to improve the quality of life of migrant workers with pneumoconiosis.

RESUMEN

Objective: To analyze the disease burden of pneumoconiosis globally and in China from 1990 to 2019 using Global Burden of Disease (GBD) 2019 data, and to provide a theoretical basis for prevention and control of pneumoconiosis. Methods: In September 2022, the data of incidence, prevalence, morality and disability-adjusted life years (DALY) of pneumoconiosis and its subtypes globally and in China from 1990 to 2019 were collected from GBD 2019, including absolute number and age-standardized rate (ASR). Joinpoint linear regression model was used to calculate average annual percent change (AAPC) and analyze the change trends of incidence, prevalence, mortality and DALY of pneumoconiosis and its subtypes. Results: From 1990 to 2019, the incident cases, prevalent cases and DALY value of pneumoconiosis showed upward trends, while the number of death cases showed downward trends. And the ASR of incidence (ASIR), the ASR of prevalence (ASPR), the ASR of mortality (ASMR) and the ASR of DALY (ASDR) showed downward trends globally and in China. China accounted for a large proportion of the global disease burden of penumoconiosis, accounting for more than 67% of the incident cases, more than 80% of the prevalent cases, more than 43% of the deaths cases and more than 60% of the absolute number of DALY in the world every year. Male were the main population of pneumoconiosis disease burden globally and in China, and the age of onset was earlier than that of female. The peak age periods of incidence, prevalence, mortality and DALY of pneumoconiosis globally and in China from 1990 to 2019 have increased. Silicosis was still the type with the highest disease burden of pneumoconiosis globally and in China. The disease burden of coal workers' pneumoconiosis had an overall improvement trend, but asbestosis had an increasing disease burden worldwide. Conclusion: The disease burden of pneumoconiosis is heavy globally and in China, which is necessary to strengthen the supervision and prevention measures according to gender, age and etiological types.

RESUMEN

Pneumoconiosis is characterized by chronic lung inflammation and fibrosis, and inflammation can promote pulmonary fibrosis, which in turn leads to pneumoconiosis. When a large shadow with a long diameter of not less than 2 cm and a short diameter of not less than 1 cm appears in the lung, it can be classified as stage Ⅲ pneumoconiosis. This paper reports a case of stage Ⅲ pneumoconiosis with a large shadow in the upper right lung accompanied by burr-like changes misdiagnosed as lung cancer by CT examination.When the large shadow lesions in patients with pneumoconiosis and lung cancer are difficult to distinguish on CT, an additional MRI examination, particularly T(2)W imaging sequence is useful sequence for identifying the two.

RESUMEN

Objective: Through comparative analysis of the disease burden of occupational pneumoconiosis in Gansu Province from 2010 to 2020, the main influencing factors are screened, and scientific basis is provided for rational allocation of limited health resources, precise management and policy implementation. Methods: In August 2021, survey and collect information on surviving occupational pneumoconiosis patients and dead occupational pneumoconiosis patients diagnosed in Gansu Province from 2010 to 2020, and analyze and calculate indicators such as morbidity, mortality, and disability adjusted of life years (DALY). Analyzing the influencing factors of disease burden usirrg multiple linear regression. Results: From 2010 to 2020, the average annual incidence of occupational pneumoconiosis in Gansu Province was 0.9992/100000, the average annual mortality was 0.897/100000, the cumulative case fatality rate was 25.75%, and the cumulative DALY was 28932.96 person-years. The first stage of occupational pneumoconiosis was the highest among DALY loss (19920.14 person-years), and the DALY loss was positively correlated with the stage of occupational pneumoconiosis. Among occupational pneumoconiosis in Gansu Province, silicosis (13753.66 person-years) and coal worker's pneumoconiosis (13414.73 person-years) caused the highest disease burden, followed by cement pneumoconiosis and asbestos lung. Period, length of service, type of disease, and region are all influencing factors of DALY loss (P<0.05). Conclusion: From 2010 to 2020, the DALY losses caused by occupational pneumoconiosis in Gansu Province showed a fluctuating decrease, with the composition of DALY mainly changing from the loss of life years due to premature death to the loss of years due to injury and disability.

RESUMEN

Objective: To explore the composition of bacteria in lower respiratory tract of patients with pneumoconiosis and dust exposure, and to compare and analyze the difference and correlation between them. Methods: From May 2020 to January 2021, a prospective multicenter cross-sectional study was conducted to select patients with pneumoconiosis who underwent bronchoalveolar lavage treatment at the Respiratory and Critical Care Medical Department of the 920th Hospital of the Joint Support Force and the Respiratory Department of Tongren Hospital in Kunming, as well as the population of dust recipients. A total of 24 patients with pneumoconiosis (pneumoconiosis group) were included, and 16 dust exposed individuals (dust exposed group) were used as controls. Two groups of patients' alveolar lavage fluid were collected. The 16SrRNA gene V3-V4 sequencing technology and bioinformatics analysis platform were used to measure and analyze the differences in microbial structure composition and associations between bacterial communities. Results: Compared with the dust exposed group, the top 5 bacterial phyla in the alveolar lavage fluid level of patients with pneumoconiosis were the same, followed by Proteobacteria, Firmicutes, Bacteroidetes, Fusobacteria, and Actinobacteria. Compared with the dust exposure group, the pneumoconiosis group patients belong to the top 5 genera of horizontal flora abundance, which are different. The dust exposure group is respectively: Pseudomonas, Proctor, Streptococcus, Achromobacter, and Neisseria. The pneumoconiosis group is respectively: Pseudomonas, Achromobacter, Streptococcus, Ralstonia, and Proctor. The Alpha diversity analysis results showed that compared with the dust exposed group, the level of bacterial diversity in the pneumoconiosis group was difference (P<0.05), and there was no statistically significant difference in bacterial evenness (P>0.05) ; Beta diversity showed differences in microbial community structure between the two groups (P<0.05 ). Single factor microbial association network analysis showed that there was a high correlation between Firmicutes and Bacteroidetes in the pneumoconiosis and dust exposed groups and other species, showing a positive correlation; The correlation between Proteobacteria and other species is high, showing a negative correlation. Conclusion: The structure and relative abundance of bacteria in lower respiratory tract were different between patients with pneumoconiosis and dust exposure, and the diversity of bacteria in lower respiratory tract increased in patients with pneumoconiosis, which may be related to disease status.

RESUMEN

Objective: To understand the social security situation of current cases of pneumoconiosis in non-coal mine industries in Jiangsu Province, and to provide reference for the treatment and security work of pneumoconiosis patients. Methods: From January to October 2020, a follow-up survey was conducted on 4038 cases of pneumoconiosis in non-coal mine industries of the province from October 1949 to December 2019. The age, type of pneumoconiosis, industry type, and social security status of the patients were collected. Namely, work-related injury insurance, employer compensation, basic medical insurance for urban and rural residents, major illness insurance, etc. SPSS 19.0 was used for statistical description and analysis. Results: The cases of pneumoconiosis in non-coal mine industries in Jiangsu Province ranged in age from 36 to 105 (70.78±8.43) years old, and had been exposed to dust for 1 to 55 (19.27±9.29) years. Silicosis was the main form (3875 cases, 95.96%), and non-metallic mining and dressing industry was the main form (2618 cases, 64.83%). A total of 3991 cases (98.84%) of pneumoconiosis patients enjoyed social security, most of them were urban and rural residents with basic medical insurance (3624 cases, 89.75%), but there were still 47 patients without any social security. 15 cases (0.37%) enjoyed the subsistence allowance, with the monthly allowance amount ranging from 104 to 3960 yuan, with the average amount of 954.87 yuan/month. Conclusion: In Jiangsu Province, the proportion of pneumoconiosis patients in non-coal mine industries enjoying social security is relatively high, but there are still patients who do not enjoy any social security, and the difference in the amount of subsistence allowance is slightly larger. It is necessary to further improve the medical security of pneumoconiosis patients and improve their quality of life.
