Protection of working mothers: operational guide document. The aim of this operational guide document is to protect the health of working mothers and their babies during pregnancy, puerperium and breastfeeding. The project was developed by a technical working group which included professionals in the pertinent fields from the Workplace Prevention and Safety Services of the local Vasta-2 Area of the Marche Regional Health Service:physicians, health assistants, and nurses. It is considered to be a useful tool for risk assessment at the workplace aimed at professionals who are involved, with various duties and responsibilities, in the health care of the working mother. This paper consists of two functionally related sections, "Table of risks" and "Technical specifications". In the "Table of Risks" section, the occupational hazards for women during pregnancy or postpartum were analyzed with the highest possible degree of care. To this end the technical group provided, for each occupational hazard, its own operational suggestions, in relation to legislation, current scientific knowledge and Guidelines of other Italian Regions. The Marche Regional Section of the Italian Society of Occupational Health and Industrial Hygiene (SIMLII) participated in the final draft of the entire document. The second section, "Technical Specifications", illustrates the main tasks and any risks involved in the 34 manufacturing sectors most prevalent in this area. This operational guide document is intended to be the beginning of a common strategy in public health to achieve a wider field of action in promotion and information aimed at protecting the reproductive health of working mothers.

Direct and Oxidative DNA Damage in a Group of Painters Exposed to VOCs: Dose - Response Relationship.

Volatile organic compounds (VOCs) are present in several working activities. This work is aimed at comparing oxidative stress and DNA damage biomarkers to specific VOCs in the occupational exposure of painters. Dose-response relationships between biomarkers of oxidative stress and of dose were studied. Unmetabolized VOCs and their urinary metabolites were analyzed. Urinary Methylhyppuric acids (MHIPPs, xylenes metabolite), Phenylglyoxylic and Mandelic acid (PGA, MA ethylbenzene metabolites), S-Benzylmercapturic acid (SBMA, toluene metabolite), and S-Phenylmercapturic acid (SPMA, benzene metabolite) were quantified at the end of work-shift. Oxidative stress was determined by: urinary excretion of 8-oxodGuo, 8-oxoGua and 8-oxoGuo and direct/oxidative DNA damage in blood by Fpg-Comet assay. Multivariate linear regression models were used to assess statistical significance of the association between dose and effect biomarkers. The regressions were studied with and without the effect of hOGG1 and XRCC1 gene polymorphisms. Statistically significant associations were found between MHIPPs and both 8-oxoGuo and oxidative DNA damage effect biomarkers measured with the Comet assay. Oxidative DNA damage results significantly associated with airborne xylenes and toluene, whilst 8-oxodGuo was significantly related to urinary xylenes and toluene. Direct DNA damage was significantly associated to SBMA. XRCC1 wild-type gene polymorphism was significantly associated with lower oxidative and total DNA damage with respect to heterozygous and mutant genotypes. The interpretation of the results requires some caution, as the different VOCs are all simultaneously present in the mixture and correlated among them.
