Abstract

This article presents a pedagogical proposal for piano training based on Guia Prático Para Piano by Heitor Villa-Lobos, grounded in the constructivist approach to education and, more specifically, in the principles of meaningful learning. From a critical and contextualised perspective, this study problematises the centrality of the Eurocentric canon in piano teaching and foregrounds the Latin American repertoire as a core axis of training. The study adopts a mixed methodological approach of a projective nature, integrating score analysis, the administration of surveys to piano teachers and students, and the conduct of semi-structured interviews with piano instructors. The analysis focuses on three pieces from Guia Prático Para Piano—"Pobre Cega”, “A pombinha voou”, and “Senhora Dona Viúva”—from which interpretative inferences are drawn and a classification by levels of difficulty within the intermediate level is proposed. The results demonstrate a positive assessment of Latin American piano repertoire and of Villa-Lobos’s work, as well as the need for systematised pedagogical guidelines for its study and implementation. It is concluded that Guia Prático Para Piano offers a pedagogically structured repertoire that fosters interpretive development from a culturally situated perspective on piano teaching.

Abstract

Atherosclerotic disease significantly impacts patients with type 2 diabetes, who often present with recalcitrant peripheral ulcers. The angiosome model of the foot presents an opportunity to perform direct angiosome-targeted endovascular interventions to maximise both wound healing and limb salvage. A systematic review was performed, with 17 studies included in the final review. Below-the-knee endovascular interventions present significant technical challenges, with technical success depending on the length of lesion being treated and the number of angiosomes that require treatment. Wound healing was significantly improved with direct angiosome-targeted angioplasty, as was limb salvage, with a significant increase in survival without major amputation. Indirect angioplasty, where the intervention is applied to collateral vessels to the angiosomes, yielded similar results to direct angiosome-targeted angioplasty. Applying the angiosome model of the foot in direct angiosome-targeted angioplasty improves outcomes for patients with recalcitrant diabetic foot ulcers in terms of primary wound healing, mean time for complete wound healing and major amputation-free survival.
