Objective: Malignant wounds due to breast cancer can present with recurrent episodes of bleeding in the tumour tissue. This study will compare the efficacy of a calcium alginate dressing (Biatain, Coloplast A/S, Denmark) and a regenerated oxidised cellulose dressing (Surgicel, Ethicon, LLC, Puerto Rico).
Protocol: A total of 24 patients with breast cancer and bleeding, malignant wounds will be enrolled in the randomised, controlled, open study, conducted at a hospital specialising in breast cancer treatment and at another hospital specialising in palliative care.
Purpose: To evaluate the most frequent surgical techniques of high-risk colorectal anastomoses in rats.
Methods: Wistar rats were enrolled in three different models comprising inflammatory (TNBS enema), vascular (portal vein occlusion) or obstructive (a non-ischemic constricting ring) mechanisms associated with colonic anastomosis that had accomplished after these former lesions. Histological analyses (Hematoxylin and eosin and Picrosirius red) were performed.
Background: Nutritional imbalance is a serious problem in developing countries, especially for the older population, which makes simple and rapid instruments for nutritional evaluation very necessary in order to have a detailed picture of the undernutrition epidemiology in those places.
Objective: This work aimed to evaluate the nutritional status of elderly institutionalized patients by use of the Mini-Nutritional Assessment (MNA) test and compare the MNA scores with some hematological variables.
Methods: We performed a cross-sectional study in elderly institutionalized patients (153) of all nursing homes in the Brazilian city of Uberlândia, using the MNA questionnaire and quantitative analysis of erythrocytes, hematocrit, hemoglobin, serum iron and transferrin.
