The vegetal biomembrane in the healing of chronic venous ulcers

BACKGROUND: The vegetal biomembrane has been used to treat cutaneous ulcers. OBJECTIVES: To assess the role of the vegetal biomembrane on the chronic venous ulcers treatment compared to treatment with collagenase cream. METHODS: Fourteen patients were selected to be treated with vegetal biomembrane and 7 with Fibrase®(CONTROL), followed clinically and photographically by the Wound Healing Index by ImageJ during 120 days and biopsied on the 1st and 30th days for histological examination. RESULTS: The vegetal biomembrane was better in promoting healing of the ulcers, especially on the inflammatory phase, confirmed by abundant exudation and wound debridement than the CONTROL group, on the 30th day. There was a greater tendency to angiogenesis followed by re-epithelialization with highest wound healing index on the 90th and 120th days. CONCLUSION: A combined analysis of clinical and histopathological findings suggests that the vegetal biomembrane acted as a factor inducing wound healing, especially on the inflammatory phase, confirmed by abundant exudation of the lesions promoting the transformation of the microenvironment of the chronic venous ulcers, and also stimulating angiogenesis and subsequent re-epithelialization.

Prevalence of overweight and obesity in elderly people from Vitória-ES, Brazil

The scope of this study was to estimate the prevalence of overweight and obesity and its association with socio-economic status in a sample of non-institutionalized elderly people from Vitória-ES, Brazil. This was a cross-sectional survey with a sample of 882 elderly people aged 60 and over. Obesity and overweight were assessed using the body mass index (BMI) and waist circumference (WC). All subjects answered a personal and socio-demographic questionnaire in relation to age, gender, marital status, physical activity, number of children, chronic diseases and smoking. Associations between categorical variables were tested using chi-square analysis with a 5% significance level. The prevalence of overweight and obesity was high (41.8% and 23.4%, respectively) and 50.7% of the elderly had a substantially increased waist circumference. About 4.3% of the individuals had diabetes, 50.4% had hypertension and 14.9% were found to have both diseases. It was observed that both the BMI and WC were significant associated (p<0.05) with sex, marital status, the presence of diseases and with cigarette smoking.

El hecho diferencial canario: ultraperiferificidad e insularidad

[ES] En este estudio su autor analiza la situación pasada y presente de Canarias, temporalmente acotada desde su entrada en la Unión Europea, hasta la obtención del Estatuto Permanente que reconoce la situación de ultraperificidad. El objetivo es analizar los cambios que está experimentando el marco institucional en el que se desenvuelve la economía y sociedad canaria. Estos cambios se refieren, fundamentalmente, a las cuestiones que tienen que ver con la reforma del Régimen Económico y Fiscal (REF) de Canarias, con el desarrollo e impacto que está teniendo el Régimen Específico de Abastecimiento (REA) sobre la economía canaria, así como al recientemente aprobado Estatuto Permanente de Canarias en la Unión Europea.
