Publications<\/h1>\n

Quality assurance and methodological improvement, alongside analytical work for diagnostics, are among Silag\u2019s activities, as is the evaluation of existing data. In recent years, a number of publications have been released by and with members of Silag.<\/p>\n

Linkage with the Swiss National Cohort<\/h2>\n

The study successfully linked data from the Swiss Laboratory for Particle Analysis (Silag) with data from the Swiss National Cohort (SNC), enabling 94% of the n = 838<\/em> cases to be linked and providing new insights into occupational groups and regional distributions of mesotheliomas. The results revealed a significant number of managers among those affected, as well as a regional cluster in the canton of Glarus.<\/p>\n

Quality control in sample preparation and analysis<\/h2>\n

In recent years, questions have arisen regarding the quality and comparability of results obtained from different available samples and preparation methods. For this reason, different sample preparation methods were performed in parallel on archived lung tissue. A comparison of results from formalin\u2011fixed wet tissue and paraffin blocks shows slightly lower levels of FB and asbestos fibers in paraffin blocks.<\/p>\n

Reference groups<\/h2>\n

The availability of reference groups is an important prerequisite for interpreting results from lung dust analyses is. This also includes an unexposed general population. In a literature review, values from around the world were compiled and compared, revealing considerable differences. In addition, asbestos levels in the general population appear to be declining over time, as observed in exposed groups. Therefore, it is important for each laboratory to establish its own reference groups and to update them over time.<\/p>\n
