Here, we report the case of a 64-year-old male miller with RPP. CASE SUMMARY The patient had a persistent cough for one month and had been clinically diagnosed with pulmonary tuberculosis in 2011. He worked in a stone processing factory from the ages of 20 through 37 and has owned his own mill for the past 25 years. His chest radiograph showed significant increases in the size and number of lung nodules since his last follow-up in 2013. By percutaneous needle lung biopsy, the nodular lesions showed diffuse infiltration of phagocytic macrophages and birefringent crystals by polarizing microscopy. He was finally diagnosed with RPP of mixed dust pneumoconiosis combined with silicosis. CONCLUSION In this case, mixed dust pneumoconiosis with silicosis might be accelerated by persistent exposure to graindust from working in a mill environment.展开更多

These data were compared withthose in 84 healthy workers (group C). Data from groupA, B exhibited mixed or obstructed ventilation dysfunction.The means of RV%, FRC% in group A were 31.2～35.6%and 56.7～59.3% respectively. These values were not onlysignificantly higher than those of the group C, but alsohigher than those of group B. The individual abnormaldetecting rates of RV% in group A, B were 26.5% and52.0% respectively, remarkably higher than 9.5% in thegroup C. It seems that RV% can be used as an individualscreening test in clinical practice. In physiologic terms,It has been recognized that FRC might more objectively.reflect the changes in quasi-static mechanics in community.The impact factors of RV might be related to quasi-staticmechanics other than to those of strength of respiratorymuscles, resistance of airway and collapsibility of bron-chial walls.展开更多

Methods: A total of 52 clinical isolated strains of M. tuberculosis L-forms were collected. rpoB gene polymorphism was analyzed by polymerase chain reaction and single-strand conformation polymorphism (PCR-SSCP) and conventional antimicrobial susceptibility test (AST). Their results were compared. Results: AST results showed that 38 of 52 clinical isolated strains were drug resistance (73.08％),while PCR-SSCP indicated 65.38％ (32/52) rpoB gene polymorphism. There was no statistic significance(χ2= 2.4914) between the 2 methods. Conclusion:Combined the application of PCR-SSCP with AST in detecting rpoB drug resistant gene polymorphism of M. tuberculosis L-form from pneumoconiosis patients with tuberculosis may have advantages at earlier diagnosis and guidance of clinical medications.展开更多

In addition to its harmful effects on the respiratory system, PNC can increase vulnerability to coronary heart disease (CHD)—the leading cause of death in the United States and in the world. Currently, two types of cardiovascular intervention procedures for CHD treatment are percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG). The objective of this study was to investigate comparative effectiveness of the two major cardiovascular intervention procedures—PCI and CABG—in PNC patients with CHD. Data from 1094 hospitalizations of adult patients with PNC and CHD (CHD-PNC patients) and 534,120 hospi-talizations of CHD patients without PNC (CHD-nonPNC) were investigated. Adjusted odds ratios for in-hospital death in relation to the type of procedure, adjusted for patient socio-demographic and clinical characteristics and hospital characteristics, were calculated using multivariable logistic regression. Men constituted 97.8% of CHD-PNC patients and 68.6% of CHD-nonPNC patients. Within the CHD-PNC group, crude (unadjusted) in-hospital mortality after CABG and PCI did not differ significantly (1.35% vs. 2.00%, p = 0.425) and remained insignificant in the multivariable analysis, adjusted for patient and hospital characteristics (adjusted OR = 0.714, 95% CI 0.220 - 2.323, p = 0.576). But in the CHD-nonPNC group, in-hospital mortality after CABG was significantly higher than after PCI both in crude analysis (2.83% vs. 1.28%,展开更多

文摘Pneumoconiosis is a restrictive lung disease mostly caused by occupational exposure to dust,including silica dust,asbestos,and other fibers.Inhalable particles smaller than 10μm can enter the bronchioles,injure lung cells,and induce lung fibrosis.This hard-to-cure disease places a substantial burden on patients and society[1].
文摘BACKGROUND Rapidly progressive pneumoconiosis(RPP) occasionally occurs in coal workers, particularly those with high exposure to silica. Here, we report the case of a 64-year-old male miller with RPP. CASE SUMMARY The patient had a persistent cough for one month and had been clinically diagnosed with pulmonary tuberculosis in 2011. He worked in a stone processing factory from the ages of 20 through 37 and has owned his own mill for the past 25 years. His chest radiograph showed significant increases in the size and number of lung nodules since his last follow-up in 2013. By percutaneous needle lung biopsy, the nodular lesions showed diffuse infiltration of phagocytic macrophages and birefringent crystals by polarizing microscopy. He was finally diagnosed with RPP of mixed dust pneumoconiosis combined with silicosis. CONCLUSION In this case, mixed dust pneumoconiosis with silicosis might be accelerated by persistent exposure to graindust from working in a mill environment.

文摘In the United States,an unexpected and severe increase in coal miners’lung diseases in the late 1990s prompted researchers to investigate the causes of the disease resurgence.This study aims to scrutinize the effects of various mining parameters,including coal rank,mine size,mine operation type,coal seam height,and geographical location on the prevalence of coal worker’s pneumoconiosis(CWP)in surface and underground coal mines.A comprehensive dataset was created using the U.S.Mine Safety and Health Administration(MSHA)Employment and Accident/Injury databases.The information was merged based on the mine ID by utilizing SQL data management software.A total number of 123,589 mine-year observations were included in the statistical analysis.Generalized Estimating Equation(GEE)model was used to conduct a statistical analysis on a total of 29,707,and 32,643 mine-year observations for underground and surface coal mines,respectively.The results of the econometrics approach revealed that coal workers in underground coal mines are at a greater risk of CWP comparing to those of surface coal operations.Furthermore,underground coal mines in the Appalachia and Interior regions are at a higher risk of CWP prevalence than the Western region.Surface coal mines in the Appalachian coal region are more likely to CWP development than miners in the Western region.The analysis also indicated that coal workers working in smaller mines are more vulnerable to CWP than those in large mine sizes.Furthermore,coal workers in thin-seam underground mine operations are more likely to develop CWP.
文摘The Residual Volume (RV) and Functional ResidualCapacity (FRC) were measured in 49 male workers exposedto cement dust (group A) and 50 male patients with pneu-moconiosis (group B). These data were compared withthose in 84 healthy workers (group C). Data from groupA, B exhibited mixed or obstructed ventilation dysfunction.The means of RV%, FRC% in group A were 31.2～35.6%and 56.7～59.3% respectively. These values were not onlysignificantly higher than those of the group C, but alsohigher than those of group B. The individual abnormaldetecting rates of RV% in group A, B were 26.5% and52.0% respectively, remarkably higher than 9.5% in thegroup C. It seems that RV% can be used as an individualscreening test in clinical practice. In physiologic terms,It has been recognized that FRC might more objectively.reflect the changes in quasi-static mechanics in community.The impact factors of RV might be related to quasi-staticmechanics other than to those of strength of respiratorymuscles, resistance of airway and collapsibility of bron-chial walls.
文摘Objective: To study the relationship between the polymorphism of drug resistant gene rpoB and drug resistance against rifampicin(RFP) of M. tuberculosis L-forms, and to evaluate its clinical application. Methods: A total of 52 clinical isolated strains of M. tuberculosis L-forms were collected. rpoB gene polymorphism was analyzed by polymerase chain reaction and single-strand conformation polymorphism (PCR-SSCP) and conventional antimicrobial susceptibility test (AST). Their results were compared. Results: AST results showed that 38 of 52 clinical isolated strains were drug resistance (73.08％),while PCR-SSCP indicated 65.38％ (32/52) rpoB gene polymorphism. There was no statistic significance(χ2= 2.4914) between the 2 methods. Conclusion:Combined the application of PCR-SSCP with AST in detecting rpoB drug resistant gene polymorphism of M. tuberculosis L-form from pneumoconiosis patients with tuberculosis may have advantages at earlier diagnosis and guidance of clinical medications.

文摘Pneumoconiosis (PNC) is a major occupational disease that develops as a result of occupational exposure to dust via inhalation. In addition to its harmful effects on the respiratory system, PNC can increase vulnerability to coronary heart disease (CHD)—the leading cause of death in the United States and in the world. Currently, two types of cardiovascular intervention procedures for CHD treatment are percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG). The objective of this study was to investigate comparative effectiveness of the two major cardiovascular intervention procedures—PCI and CABG—in PNC patients with CHD. Data from 1094 hospitalizations of adult patients with PNC and CHD (CHD-PNC patients) and 534,120 hospi-talizations of CHD patients without PNC (CHD-nonPNC) were investigated. Adjusted odds ratios for in-hospital death in relation to the type of procedure, adjusted for patient socio-demographic and clinical characteristics and hospital characteristics, were calculated using multivariable logistic regression. Men constituted 97.8% of CHD-PNC patients and 68.6% of CHD-nonPNC patients. Within the CHD-PNC group, crude (unadjusted) in-hospital mortality after CABG and PCI did not differ significantly (1.35% vs. 2.00%, p = 0.425) and remained insignificant in the multivariable analysis, adjusted for patient and hospital characteristics (adjusted OR = 0.714, 95% CI 0.220 - 2.323, p = 0.576). But in the CHD-nonPNC group, in-hospital mortality after CABG was significantly higher than after PCI both in crude analysis (2.83% vs. 1.28%,

文摘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.

文摘Cumulative inhalation of respirable coal mine dust(RCMD)can lead to severe lung diseases,including coal worker's pneu-moconiosis(CWP),silicosis,mixed dust pneumoconiosis,dust-related diffuse fibrosis(DDF),and progressive massive fibrosis(PMF).Statistics from the number of reported cases showed a significant decrease in the progression of respiratory diseases in the 1990s.However,an unexpected increase in the number of CWP cases was reported in the late 1990s.To date,there has been no comprehensive systematic review to assess all contributing factors to the resurgence of CWP cases.This study aims to investigate the effects of various mining parameters on the prevalence of CWP in coal mines.A systematic review using the preferred reporting items for systematic reviews and meta-analysis(PRISMA)method was conducted to investigate the health effects of RCMD exposure and identify the factors that may contribute to the recent resurgence of CWP cases.The systematic review yielded a total of 401 papers,which were added to the database.The total number of 148 and 208 papers were excluded from the database in the process of screening and eligibility,respectively.Then,18 papers were considered for data selection and full-text assessment.The review revealed that factors including geographic location,mine size,mining operation type,coal-seam thickness,coal rank,changes in mining practices,technology advancement,and engi-neering dust control practices are contributing to the recent resurgence of CWP among coal workers.However,the evidence for root causes is limited owing to the methodological constraints of the studies;therefore,further detailed studies are needed.

文摘Background:Pneumoconiosis is the most widely distributed occupational disease worldwide.China is currently the largest coal producer and consumer and the country with the most coal miners and cases of coal workers’pneumoconiosis(CWP).Despite more than 70 years of effort,the problem of CWP and silicosis remains serious.There is a lack of analysis of direct data on coal miners’pneumoconiosis from all over the country.This study aimed to describe the epidemiology of coal miners’pneumoconiosis and reveal some important clues regarding its social determinants.Methods:The annual incidence rate,20-year prevalence rate,and incidence rate of coal miners’pneumoconiosis per million tons in China from 1949 to 2021 were calculated by using the data of annual number of coal miners’pneumoconiosis diagnosed and reported from the coal mining and dressing industry,the number of coal miners,and the raw coal production,and the relationship between the incident cases of coal miners’pneumoconiosis and the death toll from coal mine safety accidents was analyzed using Pearson correlation analysis,with the aim of exploring the relationship between the incident cases of coal miners’pneumoconiosis and its social determinants with an ecological study.Results:From 1949 to 2021,there have been more than 462,000 patients with coal miners’pneumoconio-sis in China,showing double U-shaped distributions with an increasing trend,accounting for about 50.5%(462,000/915,000)of all diagnosed pneumoconiosis in China,while the incidencet rate of coal miners’pneu-moconiosis presents a large W shaped distribution with three peaks over a time span of more than 50 years.From 1949 to 1986,there was a strong correlation between the incident cases of coal miners’pneumoconiosis and raw coal production,the number of coal miners,and the number of deaths from coal mine accidents(r=0.849,P<0.001;r=0.817,P<0.001;r=0.697,P<0.001,respectively),but there was no such correlation found from 1987 to 2006.It was estimated that the annual incidence rate of coal miners’pneumoconiosis in China from 2016 to 2020 was 3.4‰(95%CI:2.6-4.3‰),and the prevalence rate across the recent 20-year observation period was 4.8%(95%CI:4.6-4.9%),both measured at the peak or around the peak over the 70 years.In particular,1963,1986,2006,and 2009 were the four important turning points in time.Conclusion:There was a sustained high level of incident cases of coal miners’pneumoconiosis with double U-shaped curve in China,which may be affected by a variety of social determinants and risk factors.
