DOI: https://doi.org/10.26694/2238-7234.7456-60 Objetivo: identificar o papel do enfermeiro na assistência às pessoas estomizadas intestinais. Metodologia: revisão integrativa da literatura, realizada nas bases de dados SciELO, PubMed, BDENF e LILACS, no período de fevereiro a maio de 2017, com recorte temporal de 2012 a 2016, utilizando os descritores: Estomia (Ostomy); Papel do enfermeiro (Role of the Nurse); Cuidados de Enfermagem (Nursing Care), totalizando 22 artigos. A questão norteadora foi: “Quais evidências estão produzidas na literatura científica sobre o papel do enfermeiro na assistência às pessoas estomizadas intestinais?”. Resultados: a atuação do enfermeiro ocorre desde a admissão do paciente ao pós-operatório tardio, perpassando todo o processo reabilitatório com ações de educação em saúde, estímulo ao autocuidado e apoio emocional. Nessa perspectiva, o enfermeiro tem atribuições que perpassam os cuidados laborais (técnicos) e assume a conduta relacional com o paciente, de forma holística. Conclusão: assim, o profissional desenvolve estratégias que intervém na autoaceitação e reinserção social, considerando as peculiaridades de cada sujeito e direcionando-o a ter uma vida com autonomia.

Antioxidants are synthetic or natural compounds capable of preventing or delaying oxidative damage caused by chemical species that can oxidize cell biomolecules, such as proteins, membranes, and DNA, leading to the development of various pathologies, such as cancer, atherosclerosis, Parkinson, Alzheimer, and other diseases serious. In this study, an amperometric biosensor was used to determine the antioxidant activity of teas and effervescent products based on vitamin C, available on the market. A sensor composed of three electrodes was used. The performance of the following electrochemical mediators was evaluated: meldola blue combined with Reineck salt (MBRS), Prussian blue (PB), and cobalt phthalocyanine (CoPC), as well as the time of polymerization in the enzymatic immobilization process and the agitation process during chronoamperometric measurements. Prussian blue proved to be more efficient as a mediator for the desired purposes. After optimizing the construction stages of the biosensor, as well as the operational parameters, it presented stability for a period of 7 months. The results clearly indicate that the biosensor can be successfully used to detect fraud in products called "antioxidants" or even in drugs containing less ascorbic acid than indicated on the labels. The detection limit was set at 4.93 µmol·L−1. [ABSTRACT FROM AUTHOR]
