“…Pneumoconiosis, an occupational disease (OD) mainly with diffuse pulmonary fibrosis, is caused by long‐term inhalation and deposition of mineral dust into the lungs . China is one of those countries with severe situation on pneumoconiosis around the world . In recent years, more than 80% of the new‐reported OD cases were pneumoconiosis, and an annual increase was observed as well.…”

Objectives The purposes of this study were to clarify (i) the prevalence of pneumoconiosis among young adults and (ii) the factors associated with pneumoconiosis among young adults to explore targeted solution for control of pneumoconiosis among young adults (aged 24‐44 years). Methods The new cases diagnosed from 2001 to 2015 (extracted from the National Occupational Disease and Occupational Health Information Monitoring System) were involved in this research, including information of employer, patient's name, date of birth, gender, date of diagnosis, first year of dust exposure, duration of exposure, aggregation etc Results A total of 1519 pneumoconiosis cases were diagnosed among young adults (21.6% of overall cases). Silicosis was the most common type with acute process of disease. Compared with overall cases, the young patients had shorter duration of exposure, more stage II/III cases and higher aggravation rate; and were even more concentrated in small and medium enterprises where more migrant workers were employed and insufficient protective measures were used. Without further regulation, the prevalence of pneumoconiosis among young adults would bring not only disease suffering for 3000 individuals and their families, but also an annual economic loss up to 180 million yuan for Hebei province till 2025. Conclusions As a typical heavily industrialized province of China, Hebei has severe situation on pneumoconiosis among young adults. Special attention and effort on silica‐contacting industries, small and medium enterprises, and migrant workers should be focused in future occupational supervision and regulation among young adults.

“…The latency period is usually more than 10 years, although it has been reported for miners working as few as 6 years in Vietnam . The recent trend of a longer latency in China may relate in part to more effective dust control protocols . A large number of CWP patients are diagnosed after a miner ceases employment .…”

Coal mine dust lung disease in the modern era

et al. 2017

View full text Add to dashboard Cite

Coal workers' pneumoconiosis (CWP), as part of the spectrum of coal mine dust lung disease (CMDLD), is a preventable but incurable lung disease that can be complicated by respiratory failure and death. Recent increases in coal production from the financial incentive of economic growth lead to higher respirable coal and quartz dust levels, often associated with mechanization of longwall coal mining. In Australia, the observed increase in the number of new CWP diagnoses since the year 2000 has necessitated a review of recommended respirable dust exposure limits, where exposure limits and monitoring protocols should ideally be standardized. Evidence that considers the regulation of engineering dust controls in the mines is lacking even in high-income countries, despite this being the primary preventative measure. Also, it is a global public health priority for at-risk miners to be systemically screened to detect early changes of CWP and to include confirmed patients within a central registry; a task limited by financial constraints in less developed countries. Characteristic X-ray changes are usually categorized using the International Labour Office classification, although future evaluation by low-dose HRCT) chest scanning may allow for CWP detection and thus avoidance of further exposure, at an earlier stage. Preclinical animal and human organoid-based models are required to explore potential re-purposing of anti-fibrotic and related agents with potential efficacy. Epidemiological patterns and the assessment of molecular and genetic biomarkers may further enhance our capacity to identify susceptible individuals to the inhalation of coal dust in the modern era.

“…Chinese is one of populations exposed to dust most widely with the highest prevalence of pneumoconiosis every year (3,4). According to the reports of 2014 National Occupational Disease published by National Health and Family Planning Commission (NHFPC) of the People's Republic of China, there were 29,972 new cases of occupational lung diseases diagnosed in 2014, 90% of which was pneumoconiosis, namely 26,873 cases.…”

Background: Pneumoconiosis is one of the most common occupational diseases, which shows the progressive and irreversible pathological changes. It ultimately can induce pulmonary failure and lead to death. To date, these patients have no curative treatment option under the current standard of care, so it is especially important to delay the onset of the disease and slow down its progression. Therefore, understanding of clinical features of pneumoconiosis is particularly critical for medical intervention. Methods:We collected the clinical data from 118 pneumoconiosis cases of miners admitted in hospital and processed the statistics analysis by using the Chi-square test and the risk assessment.Results: Compared to other types of miners, gold miners are liable to cause Broncho-pulmonary coinfection with Chi-square value 18.748 and the P value <0.001. However, unexpectedly, the smoking miners displayed a better Activities of Daily Living (ADLs) compared to non-smokers, which showed 19.318 of Chi-square score and less than 0.001 of P value. And this connection was associated with the dust exposure time (P<0.05), showing the increasing risk of non-smoking miners occurred as the increasing time exposed to dust. In addition, our analysis indicated that the probability of smoking miners suffered from Bronchopulmonary co-infection was less than non-smoking miners with Chi-square value 8.044 and P<0.01, which was also associated with the dust exposure time tendentiously, though P>0.05. Moreover, smoking history exhibited a deteriorating effect to the overall survival (OS) with 9.546 of Chi-square value and P<0.05, in accordance with smoking reducing life time. Interestingly, pneumoconiosis drugs could extend the smokers' OS, but not non-smokers'.Conclusions: Our studies suggest that the history of smoking and exposure time of dust play important roles in the development of pneumoconiosis and smoking could be a factor that determines the treatment options depending on patients' smoking history.
