Sex-Specific Associations Between Preoperative Hemoglobin and Outcomes After Major Noncardiac Surgery: A Retrospective Cohort Study.
Preoperative anemia is an established risk factor for morbidity and mortality after surgery. Men and women have different hemoglobin concentrations and are at different risks of postoperative complications. However, sex-stratified analysis on the association between preoperative hemoglobin and outcomes after noncardiac surgery has been limited in previous studies. ⋯ Low preoperative hemoglobin was associated with a higher risk of complications or mortality after elective noncardiac surgery in both men and women. No differences in the strength of associations between sexes were found. Further studies are needed to assess whether these associations are linear or there are sex-specific thresholds of preoperative hemoglobin concentrations below which postoperative risks begin to increase.

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.

Outcomes of Gastrostomy and Tracheostomy in Infants Undergoing Truncus Arteriosus Repair: Database Study Using the Pediatric Health Information System.
We sought to determine the prevalence of and factors associated with gastrostomy tube placement and tracheostomy in infants undergoing truncus arteriosus repair, and associations between these procedures and outcome. ⋯ In infants undergoing truncus arteriosus repair, tracheostomy is associated with greater odds of mortality; while gastrostomy and tracheostomy are strongly associated with greater odds of prolonged postoperative LOS.
