Inhibition of Neogenin Dampens Hepatic Ischemia-Reperfusion Injury.
Liver ischemia and reperfusion injury is a common source of significant morbidity and mortality following liver transplantation, hemorrhagic shock, or major hepatic surgery. Based on studies showing a critical role for the neuronal guidance receptor neogenin (Neo1) outside the nervous system in mediating tissue adaption during acute inflammation, we hypothesized that Neo1 enhances hepatic ischemia and reperfusion injury. ⋯ These data provide a unique role for Neo1 in the development of hepatic ischemia and reperfusion injury and identified Neo1 as a potential target to prevent liver dysfunction in the future.

Randomized Controlled Trial Multicenter Study
Effects of dexamethasone on cognitive decline after cardiac surgery: a randomized clinical trial.
Cardiac surgery can be complicated by postoperative cognitive decline (POCD), which is characterized by impaired memory function and intellectual ability. The systemic inflammatory response that is induced by major surgery and cardiopulmonary bypass may play an important role in the etiology of POCD. Prophylactic corticosteroids to attenuate the inflammatory response may therefore reduce the risk of POCD. The authors investigated the effect of intraoperative high-dose dexamethasone on the incidence of POCD at 1 month and 12 months after cardiac surgery. ⋯ Intraoperative high-dose dexamethasone did not reduce the risk of POCD after cardiac surgery.

Cognitive Outcome after Spinal Anesthesia and Surgery During Infancy.
Observational studies on pediatric anesthesia neurotoxicity have been unable to distinguish long-term effects of general anesthesia (GA) from factors associated with the need for surgery. A recent study on elementary school children who had received a single GA during the first year of life demonstrated an association in otherwise healthy children between the duration of anesthesia and diminished test scores and also revealed a subgroup of children with "very poor academic achievement" (VPAA), scoring below the fifth percentile on standardized testing. Analysis of postoperative cognitive function in a similar cohort of children anesthetized with an alternative to GA may help to begin to separate the effects of anesthesia from other confounders. ⋯ We found no link between duration of surgery with infant SA and scores on academic achievement testing in elementary school. We also found no relationship between infant SA and surgery with VPAA on elementary school testing, although the CIs were wide.

Randomized Controlled Trial
Erythropoietin and Protection of Renal Function in Cardiac Surgery (the EPRICS Trial).
To date, there are no known methods for preventing acute kidney injury after cardiac surgery. Increasing evidence suggests that erythropoietin has renal antiapoptotic and tissue protective effects. However, recent human studies have shown conflicting results. The authors aimed to study the effect of a single high-dose erythropoietin preoperatively on renal function after coronary artery bypass grafting in patients with preoperative impaired renal function. ⋯ Intravenous administration of a single high-dose (400 IU/kg) erythropoietin did not have a renal protective effect on patients with reduced kidney function undergoing coronary artery bypass surgery.
