Desenvolvimento e validação de material educacional para pacientes com insuficiência cardíaca / Development and validation of educational material for patients with heart failure / Desarrollo y validación de material educativo para pacientes con insuficiencia cardíaca

Objetivo: Desenvolver e validar um folder educativo para uso em pessoas com Insuficiência Cardíaca. Métodos: Estudo metodológico para elaboração de folder educativo e validação por especialistas. Os juízes técnicos foram enfermeiros especialistas em cardiologia, que validaram conteúdo e aparência, e designers gráfico validaram a aparência, estética e a comunicação visual. O Índice de Validade de Conteúdo (IVC) foi calculado, as respostas foram consistentes quando Alfa de Cronbach> 0,60 e o índice de concordância entre avaliadores (IRA) foi calculado. Resultados: Alta concordância entre enfermeiros (IRA = 1), consistência interna quase perfeita (Alfa de Cronbach = 0,84), IVC total e isolado acima de 0,8. A cartilha foi considerada válida. Para os designers gráficos, o IVC geral obteve um valor que garantiu a validade de aparência. Conclusão: A cartilha educativa foi validada pelos juízes e apresenta-se como instrumento para auxiliar no preparo para alta e acompanhamento em longo prazo de pacientes com IC. (AU)

Objective: To develop and validate an educational folder for use in people with Heart Failure. Methods: Study with a methodological approach for the elaboration of an educational folder and validation by experts. Technical specialists were nurses, cardiology specialists, who validated content and appearance; Specialist designers validated appearance, aesthetics and visual communication. The content validity index (IVC) was calculated; responses were consistent when Cronbach's alpha > 0.60 and the inter-rater agreement index (IRA) was calculated. Results: High agreement among nurses (ARI = 1), almost perfect internal consistency (Cronbach's alpha = 0.84), total and isolated CVI above 0.8. The booklet was considered valid. For graphic designers, the overall IVC achieved a value that guaranteed appearance validity. Conclusion: The educational booklet was validated by the judges and is presented as an instrument to assist in the preparation for discharge and long-term follow-up of patients with HF. (AU)

Effects of Qualea grandiflora Extract on the Expression of MMP-14 and HIF-1α in Cultured Fibroblasts and Preosteoblasts

Abstract Background: Qualea grandiflora (QG) (Vochysiaceae), also known as "pau-ferro", "pau-terra" or "pau-de-tucano", is a very common deciduous tree in the Brazilian Cerrado used in traditional medicine to treat inflammations, ulcers, diarrhea, and infections. There are reports in the scientific literature that demonstrate the medicinal effects of the bark and leaf of the QG. However, studies involving this plant are rather imited. Aim of the study: To perform the phytochemical analysis of the QG hydroalcoholic extract (HAE) of leaves, and to investigate it effects on fibroblast and preosteoblasts. Methods: Phytochemical analysis was done by HPLC-DAD. Murine NIH/3T3 fibroblasts and MC3T3-E1 preosteoblasts cell lines (ATCC) were used for the experiments. Cell viability was assessed by the MTT colorimetric assay and the expression of MMP-14 and HIF-1α by immunofluorescence. Results and conclusion: The following compounds were identified by HPLC-DAD, such as quinic acid, ethyl galate, ellagic acid derivatives as O-methylellagic acid O-galloyl, O-methylellagic acid O-deoxyhexoside, galloyl derivatives, flavonol glycoside as kaempferol-O-deoxyhexoside, quercetin-O-deoxyhexoside, myricetin-O-deoxyhexoside and the pentacyclic triterpene arjunglucoside. Cell viability results demonstrated no cytotoxic effects in the studied concentrations. We found in QG HAE some compounds with therapeutic properties that can increase the expression of MMP-14 and HIF-1α, in fibroblasts and preosteoblasts. These data suggest that QG HAE has an action on these two molecules widely involved in physiological conditions, such as collagen remodeling, bone development and growth and pathological processes as HIF signaling in cancer metastasis.
