Objectives: to analyze changes in knowledge and practices regarding silicosis in groups of workers at high risk of silicosis before - after an intervention. Methods: The study was conducted from 2018 to 2019 based on structured questions related to knowledge and practices of silicosis of workers directly exposed to silica dust in a Northern province of Vietnam. The mobile app-based intervention was applied to steel workers, then compared with ironworkers in improvements in silicosis knowledge and practices. Results: Significant changes in the intervention group related to workers' knowledge about the signs suggestive of silicosis, disease consequences, measures to reduce the risk of silicosis, and participation in annual occupational disease examinations were reported. Conclusion: Mobile applicationbased interventions could improve silicosis knowledge and practice among workers at high risk of exposure to silica dust.

Wśród form krystalicznej krzemionki (minerałów zbudowanych z ditlenku krzemu), które najpowszechniej występują w środowisku naturalnym i w środowisku pracy, są kwarc i krystobalit. Są one wykorzystywane w różnych gałęziach przemysłu, m.in. w branży ceramicznej, szklarskiej czy budowlanej, i stanowią poważne zagrożenie dla zdrowia pracowników. Frakcja respirabilna krzemionki krystalicznej (FRKK), która przedostaje się do obszaru wymiany gazowej płuc, wywołuje przewlekłe reakcje zapalne, następnie zmiany zwłóknieniowe tkanki płucnej i w efekcie pylicę krzemową, często prowadzącą do raka płuc. Zarówno pracodawcy, jak i osoby zarządzające bhp, mają duże trudności z interpretacją oraz stosowaniem przepisów prawnych dotyczących pomiarów stężeń FRKK (w celu oceny narażenia zawodowego) i klasyfikacji prac w narażeniu na respirabilny pył powstający w trakcie procesów technologicznych. Informacje przedstawione w artykule powinny pomóc w rozwiązywaniu tych problemów.

Among the forms of crystalline silica (silicon dioxide minerals) that are most common in the natural and work environments are quartz and cristobalite. They are used in various industries, including in the ceramics, glass and construction industries and pose a serious health risk to workers. The respirable of crystalline silica (RCS), which penetrates into the gas exchange area of the lungs causes chronic inflammatory reactions, followed by fibrotic changes in the lung tissue and, as a result, silicosis pneumoconiosis, often leading to lung cancer. Both employers and health and safety managers have great difficulties with the interpretation and application of legal provisions concerning the measurement of RCS concentrations (for the purpose of occupational exposure assessment) and the classification of work involving exposure to respirable dust generated during technological processes. The information in this article should help you resolve these issues.

The studFigy aims to determine the TNF-α single-nucleotide polymorphism TNF-α (-308) and assess the association of TNF-a(-308) SNP with the risk of silicosis among workers directly exposed to silica dust in Vietnam. A study was undertaken among 78 cases with silicosis and 103 controls without silicosis in Vietnam. Blood samples were collected for genomic DNA extraction from each subject. The phenotyping of TNF-α(-308) was performed using polymerase chain reaction‐based restriction fragment length polymorphism (PCR‐RFLP) and dye termination sequencing. Results: The average exposure time of the case group was slightly higher than that of the control group (12.46 ± 6.732 years vs. 12.09 ± 7.854 years). The majority of genotypes in both silicosis and non-silicosis was GG. When analyzing the concentration of TNF-α in the study participants' blood, it is shown that the average concentration of TNFα in the case group was higher than that in the control group. The genotype AG in the case group was 1.368 times higher than that in the control group. The percentage of all A alleles in the case group with silicosis was 1.342 times higher than the control group without the disease, similar to previous studies. Conclusion: The majority of genotypes in both groups was GG. The average concentration of TNF-α in blood, genotype AG, and the percentage of all A alleles in the case group was higher than that in the control group.
