With estimated global postoperative mortality rates at 1% to 4% leading to approximately 3 million to 12 million deaths per year, an urgent need exists for reliable measures of perioperative risk. Existing approaches suffer from poor performance, place a high burden on clinicians to gather data, or do not incorporate intraoperative data. Previous work demonstrated that intraoperative anesthetics induce prefrontal electroencephalogram (EEG) oscillations in the alpha band (8 to 12 Hz) that correlate with postoperative cognitive outcomes. ⋯ Intraoperative EEG alpha power is independently associated with postoperative mortality and adverse outcomes, suggesting it could represent a broad measure of postoperative physical resilience and provide clinicians with a low-burden, personalized measure of postoperative risk.

Multicenter Study Observational Study
Postoperative lymphopaenia as a risk factor for postoperative infections in cancer surgery: A prospective multicentre cohort study (the EVALYMPH study).
Stress due to surgical trauma decreases postoperative lymphocyte counts (LCs), potentially favouring the occurrence of postoperative infections (PIs). ⋯ POD1 lymphopaenia was associated with PIs in patients undergoing thoracic or gastrointestinal cancer surgery. To individualise care, patient characteristics and surgery duration should be taken into account.

The incidence of hepatocellular carcinoma (HCC) is on the rise worldwide, due to the increasing prevalence of liver diseases associated with metabolic dysfunction and better management of cirrhosis and its complications. The diversification of HCC treatments has recently increased, with the choice of strategy based on HCC characteristics, liver function and comorbidities. The combination of new therapies has transformed the prognosis, with up to 70% survival at 5 years. ⋯ The importance of preanaesthetic evaluation will depend largely on the procedure proposed, associated co-morbidities and the stage of liver disease. This assessment should verify stabilisation of all comorbidities, and evaluate the degree of portal hypertension, cirrhosis severity and sarcopenia. Liver resection and liver transplantation for HCC present specific surgical challenges, and minimally invasive techniques improve recovery. Nonsurgical procedures considered as therapeutic (ablation) or standby (regional embolisation) are diverse, and all expose patients to specific intra-anaesthetic complications, sometimes requiring intensive care management. Peri-operative anaesthetic strategies deployed in the management of liver resection or nonsurgical procedures involve specific management of fluids, coagulation, narcosis and analgesia, which can impact on patients' overall, and cancer prognosis. Lastly, new down-staging strategies combining several types of procedure and possibly immunotherapy, also call for collegial reflection on posthepatic transplant immunosuppression, which must remain tailored to each individual patient.
