Abstract
Arsenic contamination in agricultural crops poses a significant risk to human health and the environment. In this study, we analyzed the environmental impact of arsenic on corn grains from the Quevedo canton in Ecuador. Rice, as a global staple food, is a potential source of exposure to arsenic, a toxic metalloid that affects both health and agriculture. The lack of updated data in the region motivated this research. Rice samples were collected from the main distributors in the canton, as well as a control sample from crops. Using graphite furnace atomic absorption spectrometry, arsenic concentrations were determined to range from 0.12 ± 0.02 mg/kg to 0.21 ± 0.06 mg/kg, with an average of 0.17 mg/kg. Although these values comply with European Union regulations (0.25 mg/kg), one sample exceeded the national limit (0.2 mg/kg), posing a risk to food safety. Statistical analysis (ANOVA and Tukey) revealed that there are no significant differences between distributors. The analysis of the environmental impacts associated with the presence of arsenic reveals that, on average, the values obtained are negative, indicating that they do not represent severe environmental damage.

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.
