Preoperative risk stratification for hepatectomy patients can aid clinical decision making. The objective of this retrospective cohort study was to determine postoperative mortality risk factors and develop a score-based risk calculator using a limited number of preoperative predictors to estimate mortality risk in patients undergoing hepatectomy. ⋯ Development of risk calculators may potentially allow surgical and anesthesia providers to provide a more transparent plan to support patients planned for hepatectomy.

Hyperoxia Increases Kidney Injury During Renal Ischemia and Reperfusion in Mice.
Renal ischemia and reperfusion (IR) contribute to perioperative acute kidney injury, and oxygen is a key regulator of this process. We hypothesized that oxygen administration during surgery and renal IR would impact postoperative kidney function and injury in mice. ⋯ In this controlled preclinical study of oxygen treatment during renal IR surgery, hyperoxia and hypoxia impaired renal function, increased renal injury, and impacted expression of genes that affect mitochondrial biogenesis and antioxidant response. These results might have implications for patients during surgery when high concentrations of oxygen are frequently administered, especially in cases involving renal IR.

Observational StudyTranslating Policy to Practice: An Association Between Medicare Access and Children's Health Insurance Program Reauthorization Act Implementation and Palliative Care Consultations and Perioperative Mortality in Critical Care.
To evaluate the 30-day postoperative mortality and palliative care consultations in patients that underwent surgical procedures in the United States before and after Medicare Access and Children's Health Insurance Program Reauthorization Act (MACRA) implementation. ⋯ We did not observe an increase in postoperative mortality after POD 30 before or after MACRA implementation. However, palliative care use markedly increased after POD 30. These findings should be considered hypothesis-generating because of several confounders.

Peri-operative complications are common and associated with high morbidity and mortality. Optimising the use of statins might be of important benefit in peri-operative care and reduce morbidity and mortality. ⋯ Adherence to guideline-recommended statin therapy was suboptimal, particularly in women. Statin use was associated with an increased risk of PMI due to T1MI and lT2MI but reduced risk of cardiovascular death and spontaneous MI within 120 days.
