Prejuízos nutricionais e distúrbios no padrão de sono de trabalhadores da Enfermagem / Nutritional damages and disturbances in the sleep pattern of nursing workers / Prejuicios nutricionales y alteraciones en los patrones de sueño de los trabajadores de Enfermería

Este artigo apresenta uma revisão integrativa das publicações científicas da última década, que investigaram os hábitos de sono, a ingestão alimentar e o estado nutricional de profissionais de enfermagem. Foram analisados artigos publicados em periódicos nacionais e internacionais no período de 2002 a 2014, disponibilizados na base de dados PubMed/MEDLINE (USA National Library of Medicine), Lilacs / SciELO (Scientific Eletronic Library Online) e Google Acadêmico. Trinta e um artigos preencheram os critérios estabelecidos. Na análise destes estudos foi identificada elevada prevalência de sobrepeso e obesidade, além de uma modificação negativa nos hábitos alimentares, bem como prejuízos na dinâmica do sono dos profissionais da área de enfermagem.

This article presents an integrative review of national and international scientific publications that investigate the sleep habits, the feed intake and nutritional status of nursing professionals. It was analyzed articles published in national and international journals in the period 2002 to 2014 and made available in the database PubMed / MEDLINE (USA National Library of Medicine), Lilacs / SciELO (Scientific Eletronic Library Online) and Google Scholar. Thirty one articles met the criteria. In the analysis of these studies it has been found a high prevalence of overweight and obesity, a negative change in the eating habits, as well as losses in the sleep patterns of nursing professionals.

Spectrophotometric determination of 6-aminopenicillanic and 7-aminocephalosporanic acids as the Schiff bases with para-dimethylaminobenzaldehyde in the presence of sodium dodecyl sulfate micelles.

Yields of colored Schiff base products of the reversible condensation of 6-aminopenicillanic and 7-aminocephalosporanic acids with para-dimethylaminobenzaldehyde in a weakly acid aqueous solution strongly increase in the presence of micelles of sodium dodecyl sulfate. The binding constants of reactants and products of both reactions to micelles were calculated from the concentration profiles of micellar effects on rates and equilibrium of the condensation reactions. The observed micellar-induced shifts of equilibrium are accompanied by strong acceleration of the forward and small retardation of backward processes. Some deviations from the theoretical profiles due to saturation of micelles with reactants were observed. The colored form of the reaction product was found to be the protonated Schiff base. Its stability in time is strongly enhanced in the micellar medium. The spectrophotometric determination of title compounds under optimum micellar conditions possesses ca. 300 times higher sensitivity than the standard procedure.
