Patients with severe grades of life-threatening brain injury are commonly characterized as having devastating brain injury (DBI), which we have defined as: 'any neurological condition that is assessed at the time of hospital admission as an immediate threat to life or incompatible with good functional recovery AND where early limitation or withdrawal of therapy is being considered'. The outcome in patients with DBI is often death or severe disability, and as a consequence rapid withdrawal of life sustaining therapies is commonly contemplated or undertaken. However, accurate prognostication in life-threatening brain injury is difficult, particularly at an early stage. ⋯ We have made 12 practical, pragmatic recommendations to help clinicians deliver safe, effective, equitable, and justifiable care within resource constrained healthcare systems. In the situation where patient-centred outcomes are recognized to be unacceptable, regardless of the extent of neurological improvement, then early transition to palliative care is appropriate. These recommendations are intended to apply where the primary pathology is DBI, rather than where DBI has compounded a progressive and irreversible deterioration in other life-threatening comorbidities.

Management of antiplatelet therapy in patients with coronary stents undergoing noncardiac surgery: association with adverse events.
Perioperative discontinuation of antiplatelet therapy (APT) in patients with coronary stents has been associated with major adverse cardiac events. Our aim was to analyse the perioperative management of APT in such patients and its relationship to the incidence of major adverse cardiac and cerebrovascular events (MACCE) and major bleeding events (MBE) in noncardiac surgery. ⋯ NCT01171612.

Previous meta-analyses on the anaesthetic management of patients undergoing surgery for hip fracture have focused on randomized trials. Furthermore, heterogeneity in outcome reporting across the studies has made it difficult to inform best practice guidelines for patient care. ⋯ We highlight the need for agreement on outcome definitions and for a minimum core outcome set to be measured and reported in hip fracture studies. This would strengthen the evidence-based approach to delivering optimal care.

Observational Study
Prognostic value of postoperative high-sensitivity troponin T in patients with different stages of kidney disease undergoing noncardiac surgery.
Emerging evidence suggests that postoperative troponin release is a strong and independent predictor of short-term mortality. However, evaluating elevated troponins in patients with chronic kidney disease (CKD) is still controversial and is often disregarded. This study examines morbidity along with short- and long-term mortality risk associated with elevated high-sensitivity troponin T (hsTnT) in patients with different stages CKD undergoing noncardiac surgery. ⋯ Elevated postoperative hsTnT is associated with a dose-dependent increase in 30-day and long-term mortality risk in each stage of CKD with an estimated glomerular filtration rate ≥30 ml min-1 1.73 m-2.

Observational Study
Association between postoperative mean arterial blood pressure and myocardial injury after noncardiac surgery.
Myocardial injury after noncardiac surgery is common, although the exact pathophysiology is unknown. It is plausible that hypotension after surgery is relevant for the development of myocardial injury. The authors evaluated whether low mean arterial pressures (MAPs) after surgery are related to an increased incidence in postoperative cardiac-troponin elevation. ⋯ Lower postoperative blood pressure is associated with an increased incidence of postoperative cardiac hsTnT elevation, irrespective of pre- and intraoperative variables.
