The aim of this study was to determine the influence of gender on in hospital outcome in patients with ST-segment elevation myocardial infarction (STEMI) who underwent primary angioplasty (PA). ⋯ In our study, female gender was an independent predictor of in-hospital mortality in patients with IAMEST treated with PA.

A near-miss event is defined as an event that could have resulted in an injury, fatality, or property damage if it had not been prevented. Analysis of near-miss events could be an efficient method in the study of adverse events. ⋯ However, up to now, this method has been slow to develop. We present two clinical cases that help to understand the usefulness of the near-miss reporting system.

Critically ill patients are threatened or affected by multi-organ failure (MOF). Tissue hypoxia is one of the most important co-factors of MOF. Venous oximetry allows the critical estimation of the global oxygen (O(2)) supply-demand ratio and can be gained from mixed (S(v)O(2)) and central venous blood (S(cv)O(2)). ⋯ Variation of cardiac output, optimisation of arterial O(2)-saturation and adaptation of O(2)-extraction are shown to be the relevant levels of pathophysiological adaptation as well as therapeutic intervention. We portray the functional equivalence of S(cv)O(2) and S(v)O(2) and analyse their diagnostic, therapeutic and prognostic significance, providing the basis for the efficacy of venous oximetry as an important marker of critical illness. Finally, having drawn an outline of current developments for the better understanding of the oxidative balance of individual organs, we stress the importance of a synoptic O(2)-monitoring strategy as well as the need to use its beneficial, yet unfulfilled, clinical potential.

Practice Guideline
[Treatment recommendations at the end of the life of the critical patient].
Admission of a patient in the Intensive Care Unit (ICU) is justified when the critical situation can be reverted or relieved. In spite of this, there is high mortality in the ICU in regard to other hospital departments. End-of-life treatment of critical patients and attention to the needs of their relatives is far from being adequate for several reasons: society denies or hides the death, it is very difficult to predict it accurately, treatment is frequently fragmented between different specialists and there is insufficient palliative medicine training, including communication skills. ⋯ The SEMICYUC Working Group of Bioethics elaborates these Recommendations of treatment at the end of the life of the critical patient in order to contribute to the improvement of our daily practice in such a difficult field. After analyzing the role of the agents involved in decision making (patient, familiar, professional, and health care institutions), of the ethical and legal foundations of withholding and withdrawal of treatments, guidelines regarding sedation in the end of the life and withdrawal of mechanical ventilation are recommended. The role of advance directives in intensive medicine is clarified and a written form that reflects the decisions made is proposed.

To analyze if the levels of von Willebrand factor (FvW) are higher in patients with ischemic heart disease than in healthy subjects and evaluate the relationship of these levels with clinical recurrence and coronary interventionism. ⋯ FvW levels reflect an endothelial alteration in patients with ischemic heart disease. The increase of the levels after coronary interventionism could be due to the endothelial aggression itself of the intervention. It was not possible to demonstrate higher levels of FvW in patients with symptoms in the three month follow-up.
