ABSTRACT
Acute kidney injury (AKI), defined as an abrupt increase in serum creatinine, a reduced urinary output, or both, is experiencing considerable evolution in terms of our understanding of the pathophysiological mechanisms and its impact on other organs. Oxidative stress and reactive oxygen species (ROS) are main contributors to organ dysfunction in AKI, but they are not alone. The precise mechanisms behind multi-organ dysfunction are not yet fully accounted for. The building up of uremic toxins specific to AKI might be a plausible explanation for these disturbances. However, controversies have arisen around their effects in organs other than the kidney, because animal models usually depict AKI as a kidney-specific injury. Meanwhile, humans present AKI frequently in association with multi-organ failure (MOF). Until now, medium-molecular-weight molecules, such as inflammatory cytokines, have been proven to play a role in endothelial and epithelial injury, leading to increased permeability and capillary leakage, mainly in pulmonary and intestinal tissues.

Resumen Actualmente, en la formación médica la enseñanza de la interpretación electrocardiográfica ha adquirido un papel secundario, y algunos médicos consideran que solo el especialista puede ser competente en esta área. Se muestra un abordaje sistemático para guiar a los estudiantes en la obtención, interpretación y aplicación de esta herramienta diagnóstica.
Abstract Currently, among the medical curricula, electrocardiogram interpretation has undergone a fallback, and some physicians consider that only the specialists can be competent in this area. A systematic approach is shown in order to aid students to obtain, interpret and execute a clinical application of this diagnostic test.
