Midwives' practices on perineal protection and episiotomy decision-making: A qualitative and descriptive study.

Introduction: Perineal trauma is associated with both short- and long-term morbidity which in turn relates to the degree of trauma. The objective of this study was to understand midwives' practices regarding perineal protection during the second phase of labor, emphasizing decision-making to perform an episiotomy.

Methods: A descriptive and explanatory study was conducted with an intentional sample of twenty-two midwives working in the labor ward of a tertiary hospital in a metropolitan location and in the public service, in Portugal.

Base excision repair (OGG1 and XRCC1) and metabolism (PON1) gene polymorphisms act on modulation of DNA damage and immune parameters in tobacco farmers.

Pesticides are one of the most frequently investigated chemical, due to their multiple uses in agricultural and public health areas. This study evaluates lymphocytes CBMN (cytokinesis-block micronucleus cytome assay), inflammatory markers, inorganic elements in blood samples, and the relationship of these parameters with XRCC1Arg194Trp, OGG1Ser326Cys and PON1Gln192Arg polymorphisms in a population of tobacco farmers. The study population comprised 129 agricultural workers exposed to pesticides and 91 nonexposed.
