Abstract
The article explores virtual educational ethnography as a methodological approach to analyze social and educational interactions in digital environments, highlighting its relevance in social sciences. The global emergency caused by COVID-19 accelerated the adoption of Information and Communication Technologies (ICTs) in education, which imposed new challenges in teaching-learning in different areas of knowledge. From a qualitative and interpretative approach, supported by virtual ethnography, the strategies, perceptions and adaptations of accounting teachers belonging to tourism programs in Colombia, who migrated to virtuality as a result of confinement, are analyzed. It is concluded that it is necessary to adapt pedagogical practices to new technological dynamics, which, although they impose challenges such as affective disconnection and limited student participation, can also constitute valuable tools to guarantee meaningful learning in students and redefine the role of teachers as experience designers and emotional mediators.

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.
