Cao and colleagues present a follow-up analysis of a previous RCT among >1200 older adults (mean age 72 yr) undergoing cancer surgery, originally designed to evaluate the effect of propofol or sevoflurane general anaesthesia on delirium, here to evaluate the effect of anaesthetic technique on overall survival and recurrence-free survival. Neither anaesthetic technique conferred an advantage on oncological outcomes. We suggest that although it is entirely plausible that the observed results are truly robust neutral findings, the present study could be limited, like most published studies in the field, by its heterogeneity and understandable absence of underlying individual patient-specific tumour genomic data. We argue for a precision oncology approach to onco-anaesthesiology research that recognises that cancer is not one but rather many diseases and that tumour genomics (and multi-omics) is a fundamental determinant relating drugs to longer-term outcomes.

Randomized Controlled Trial
Palonosetron as prophylaxis for post-discharge nausea and vomiting: a prospective, randomised, double-blind, placebo-controlled trial in ambulatory surgery.
Approximately 25% of ambulatory surgery patients experience post-discharge nausea and vomiting (PDNV). We aimed to investigate whether palonosetron, a long-acting anti-emetic, decreases the incidence of PDNV in high-risk patients. ⋯ EudraCT 2015-003956-32.

The prevalence of diabetes is increasing, and patients with diabetes mellitus have both an increased likelihood of requiring surgery and of developing postoperative complications when they do. We summarise available evidence underpinning current guidelines on preoperative assessment and optimisation, perioperative management of prescribed insulin and oral hypoglycaemic medication, intraoperative glycaemic control, and postoperative patient care.

Randomized Controlled Trial
Perioperative changes in neurocognitive and Alzheimer's disease-related cerebrospinal fluid biomarker in older patients randomised to isoflurane or propofol for anaesthetic maintenance.
Animal studies have shown that isoflurane and propofol have differential effects on Alzheimer's disease (AD) pathology and memory, although it is unclear whether this occurs in humans. ⋯ NCT01993836.

There is a lack of consistent, evidence-based guidelines for the management of patients with fever after brain injury. The aim was to update previously published consensus recommendations on targeted temperature management after intracerebral haemorrhage, aneurysmal subarachnoid haemorrhage, and acute ischaemic stroke in patients who require admission to critical care. ⋯ Based on a modified Delphi expert consensus process, these guidelines aim to improve the quality of targeted temperature management for patients after intracerebral haemorrhage, aneurysmal subarachnoid haemorrhage, and acute ischaemic stroke in critical care, highlighting the need for further research to improve clinical guidelines in this setting.
