Medical Research: What is the background for this study? What are the main findings?

In 2007, we evaluated 145 former male denim sandblasters who had an exposure history to at least 1 month with a latency period at least ten months; 77 (53%) were diagnosed as silicosis according to the profusion category of opacities of 1/0 or greater. In this study, we reported 4-year follow-up results of this cohort. Out of 83 sandblasters who were evaluated in this follow-up study, nine died and of the remaining 74, 96% had radiographic evidence of silicosis based on the same criteria and 66% had pulmonary function loss, which was defined as at least 12% or more decrease on FVC, predicted.
