[Acute respiratory distress syndrome: a review of the Berlin definition].
Acute Respiratory Distress Syndrome (ARDS) is due to many causes. The absence of a universal definition up until now has led to a series of practical problems for a definitive diagnosis. ⋯ However, 18 years later, in 2011, the European Intensive Medicine Society, requested a team of international experts to meet in Berlin to review the ARDS definition. The purpose of the Berlin definition is not to use it as a prognostic tool, but to improve coherence between research and clinical practice.

[Hyperlactatemia in surgical ablation of atrial fibrillation and cardiac surgery. Is it a predictive factor of postoperative morbidity?].
Increased serum lactate in postoperative cardiac surgery is very common and its pathogenesis is due to multiple factors. The elevation of serum lactate is associated with tissue hypoxia (hyperlactatemia type A) and non-hypoxic (hyperlactatemia type B) metabolic disorders. The aim of the study was to assess the evolution of postoperative lactate in surgical atrial fibrillation ablation during cardiac surgery, and to determine whether lactate levels could be predictors of morbimortality. ⋯ The atrial fibrillation surgical ablation may be a not-yet-described cause of type B hyperlactatemia, with serum peak values being reached between 4-24h after cardiac surgery. The predictive value of this elevation, its correlation with morbimortality, its sensitivity and specificity to discriminate the significant thresholds needs to be defined.
