An HPLC analytical method combining methanol-deionised water (80:20, v/v) extraction, methanol-acetonitrile (50:50, v/v) extraction and fluorescence detection was implanted to analyse ochratoxin A and aflatoxins B1, B2, G1 and G2 of air samples collected during the usual production process in a number of workplaces of a coffee factory to assess the occupational exposure of the engaged workers. The average levels of airborne ochratoxin A and aflatoxins were less than 1.2 and 0.

Background: This study has researched the cost-effectiveness of Early Diagnosis of Breast Cancer in Catalonian women in the 50-64 age group.
Methods: The cost-effectiveness ratio was obtained by comparing the costs of a program for 100,000 women with results achieved. The program consisted of a twice yearly mammography on all of the women over a 10 year period.
Background: The cost-effectiveness of the following methods of cessation of smoking were calculated in this study: 1) medical advice, 2) medical advice and nicotine chiclets, and 3) medical advice and nicotine patches.
Methods: The costs and effectiveness of the methods of cessation of smoking compared in terms of cost per year of life gained, deducing the costs and benefits at 5%.
Results: The cost per year of life gained was found to be 260,000 to 434,000 pesetas in males and 441,000 to 637,000 in women for medical advice, 287,000 to 479,000 in males and 486,000 to 703,000 in females for advice and nicotine chiclets and 329,000 to 549,000 in males and 557,000 to 805,000 in females for advice and nicotine patches.
