RESUMOAs transformações experimentadas pela sociedade contemporânea trouxeram novo ritmo e modo de vida. Porém, nelas estão associados problemas como alimentação incorreta, sedentarismo e estresse, elementos desencadeadores de doenças crônico-degenerativas, como as cardiopatias, o diabetes melito e a síndrome metabólica. Uma das alternativas buscadas pelas ciências médicas, em associação com outras áreas do conhecimento, são as pesquisas acerca de nutrientes que tragam contributos a saúde. O presente trabalho apresenta uma revisão de estudos recentes sobre o papel dos fatores nutrológicos na prevenção e combate às morbidades associadas à síndrome metabólica (SM) e traz apontamento para novos estudos que avaliem o papel da nutroterapia na SM, em especial a inserção de alimentos com propriedades antioxidantes nos tratamentos preventivos.
ABSTRACTThe changes experienced by contemporary society brought new rhythm and way of life. However, problems are associated with them: incorrect diet, sedentary lifestyle and stress trigger of many chronic degenerative diseases, like heart disease, diabetes and metabolic syndrome (MS). One of the alternatives sought by the medical sciences, in association with other areas of knowledge, is the research regarding nutrients that might contribute to health. This review presents recent work on the role of dietary factors in preventing and combating the morbidity associated with MS, in particular the inclusion of foods with antioxidant properties for preventive treatments.
Breast cancer is a sad reality all over the world, the second most frequent type among women, therefore a serious public health concern. For it diagnosis, mammography is performed and interpreted by qualified medical radiologists. However, several factors have limited the correct interpretation of mammographic images, as visual fatigue, stress and professional distraction, which may result in failed or delayed diagnosis. It's possible to minimize the error rate performing the analysis by means of double reading or by the support of computational schemes (CAD) in order to act as a second opinion. The aim of this study was evaluate the impact of CAD on the interpretation of mammographic images performed by experienced radiologists, aiming to detect nodules and clusters of calcifications (CADe) and as classifier nodules tool (CADx). The results showed that CAD has positively influenced the diagnostic accuracy when used as a classifier, increasing the sensitivity and specificity of radiologists with the advantage of not significantly increasing the rate of false positives. This shows that the CAD really improved the diagnosis, being a useful tool in the analysis of mammographic images.. Additional tests including more samples and analyzers should be performed according to this approach. Future studies could specifically explore the performance of CADx schemes when applied exclusively to the analysis of dense breasts, where the radiological signs are not so obvious, which is a serious difficulty for the medical examination.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
