Medidas de autocuidado para prevenção da recidiva de úlceras venosas: protocolo de revisão de escopo / Self-care measures to prevent venous ulcer recurrence: a scoping review protocol

OBJETIVO: Mapear as medidas de autocuidado para prevenção de recidiva de úlceras venosas nos diversos cenários de atenção à saúde. MÉTODO: Protocolo de revisão de escopo, tendo como pergunta de pesquisa: quais as medidas de autocuidado para prevenção de recidiva de úlceras venosas nos diversos cenários de atenção à saúde? Serão utilizados como bases de dados: Banco de Dados em Enfermagem (BDENF), CINAHL, LILACS, MEDLINE (via PUBMED), SCIELO, SCOPUS, Cochrane Library, EMBASE e Web of Science, além da literatura cinzenta. O processo de busca, a avaliação, seleção e extração de dados serão realizados por pares cegados e, em caso de divergência, um terceiro revisor será consultado. Os resultados serão apresentados na íntegra, em formato de narrativa e diagramas de fluxo, de forma a se alinhar à questão de pesquisa proposta. Protocolo registrado na Open Science Framework (OSF): osf.io/y7ckp.

OBJECTIVE: To map self-care measures to prevent venous ulcer recurrence in different healthcare settings. METHOD: Scoping review protocol, with the following research question: What are the self-care measures to prevent the recurrence of venous ulcers in different healthcare settings? The following databases will be used: Nursing Database (BDENF), CINAHL, LILACS, MEDLINE (via PUBMED), SCIELO, SCOPUS, Cochrane Library, EMBASE, and Web of Science, in addition to the grey literature. Blinded peers will carry out the search process, evaluation, selection, and data extraction, and in case of disagreement, a third reviewer will be consulted. The results will be presented in narrative format and using flow diagrams aligned with the proposed research question. The protocol was registered in the Open Science Framework (OSF): osf.io/y7ckp.

Cardiomyocyte volume-weighted nuclear volume and spironolactone therapy in spontaneously hypertensive rats.

OBJECTIVE: To evaluate the blood pressure (BP) and cardiomyocyte nuclei hypertrophy of spontaneously hypertensive rats (SHR) treated with spironolactone and with spironolactone and an angiotensin-converting enzyme inhibitor and calcium channel blocker. STUDY DESIGN: Six groups with 5 SHR each were treated for 13 weeks: control group, spironolactone groups (5, 10 and 30 mg/kg/d, or low, moderate and high doses, respectively), and spironolactone and enlapril or/and verapamil. Blood pressure (BP) and cardiomyocyte volume-weighted nuclear volume (VWNV) were studied. RESULTS: The usual evolution of BP in young adult SHR was greatly altered by spironolactone treatment, with either attenuation or reversion of the BP tendency to increase. The treatments efficiently reduced the cardiomyocyte VWNV > 45%, confirming efficient action of both spironolactone monotherapy at moderate and high dose and spironolactone combined with enalapril or verapamil. However, the high dose of spironolactone, and spironolactone plus enalapril or verapamil showed no significant differences in cardiomyocyte VWNV. Correlation between VWNV and BP (13th week) suggested that BP degree influences cardiomyocyte VWNV. CONCLUSION: The effect of spironolactone monotherapy seems to be dose dependent, and the combination with enalapril or verapamil improves spironolactone efficiency in BP reduction but not in prevention/attenuation of cardiac myocyte nuclear hypertrophy.
