Shared decision-making is advocated because of its potential to improve the quality of the decision-making process for patients and ultimately, patient outcomes. However, current evidence suggests that shared decision-making has not yet been widely adopted by health professionals. Therefore, a systematic review was performed on the barriers and facilitators to implementing shared decision-making in clinical practice as perceived by health professionals. ⋯ This systematic review reveals that interventions to foster implementation of shared decision-making in clinical practice will need to address a broad range of factors. It also reveals that on this subject there is very little known about any health professionals others than physicians. Future studies about implementation of shared decision-making should target a more diverse group of health professionals.

Quantitative acid-base physiology using the Stewart model. Does it improve our understanding of what is really wrong?
Traditional theories of acid-base balance are based on the Henderson-Hasselbalch equation to calculate proton concentration. The recent revival of quantitative acid-base physiology using the Stewart model has increased our understanding of complicated acid-base disorders, but has also led to several new controversies. With the help of three patient histories, we show that the Henderson-Hasselbalch equation should be regarded as a simplified version of the more general Stewart model and not as something completely different. Therefore, both models may be useful at the bedside.

Perceptions of patients on the utility or futility of end-of-life treatment.
Definitions of medical futility, offered by healthcare professionals, bioethicists and other experts, have been rigorously debated by many investigators, but the perceptions of patients of futility have been explored only by a few. Patients were allowed to discuss their concerns about end-of-life care, so that their ideas about treatment futility or utility could be extrapolated by us. ⋯ Although the terms "utility" or "futility" were not generally used by the participants, segments of speech indicating their perceptions of these terms were identified. Treatment was not always discussed in the same way by patients and providers, but seemed to reflect the same four concerns. Therefore, it may be fruitful for providers to focus on these concerns when discussing end-of-life treatment options with their patients.

Takayasu's arteritis (TA) is a chronic large vessel vasculitis. The physiopathology of TA has not been completely elucidated, but it appears to be multifactorial and to mainly involve cellular immunity. The pathologic sequence could implicate stimulation from an antigen that triggers heat shock protein (HSP)-65 expression in aortic tissue which, in turn, induces MHC class I-related chain A (MICA). ⋯ The use of corticosteroids and of other immunosuppressive agents can bring TA into remission in most patients. A better understanding of the immunological mechanisms responsible for the vascular injury has led to trials of anti-TNF-alpha agents with encouraging results. In the near future, new drugs specifically designed to target some of the mechanisms described above may be able to expand the physician's therapeutic arsenal in TA.

Impact of the use of aminoglycosides in combination antibiotic therapy on septic shock and mortality due to Staphylococcus aureus bacteremia.
The purpose of this study was to evaluate the possible impact of antimicrobial combination regimens containing an aminoglycoside (AG) on morbidity and mortality associated with S. aureus bacteremia. ⋯ Although there was no decrease in mortality due to S. aureus infection in patients treated with AG therapy, we found a significant benefit of AG in preventing septic shock. This data argues for the early use of AG in patients with S. aureus bacteremia.
