Abstract

Colombia is a country where SMEs make up the majority of the business fabric, generating employment and contributing significantly to GDP, although they face limitations in innovation and technological adoption that affect their productivity and profitability. In this context, variables such as research and development (R+D) and innovation are recognized as strategic elements to strengthen business performance and economic growth. However, gaps in technological capabilities, access to resources, and knowledge networks continue to limit the productive sector. Therefore, this study seeks to empirically analyze the relationship between innovation, R+D, total factor productivity (TFP) and return on assets (ROA) in the Colombian industrial sector, using data from the EAM and EDIT of DANE (2013–2022) and the Levinsohn and Petrin method to estimate these effects more accurately according to firm size. The findings will make it possible to identify differential policies that promote innovation effectively, adapted to the characteristics of each type of company.

Keywords : Innovation, Research and Development (R+D), Total Factor Productivity (TFP), Return on Assets (ROA), SMEs, Colombian industrial sector..

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.
