Sivelestat sodium hydrate is a specific neutrophil elastase inhibitor effective in acute lung injury (ALI) associated with systemic inflammatory response syndrome. Bowel ischemia reperfusion injury (IRI) induced by supravisceral aortic clamping is associated with an excessive systemic inflammatory response, resulting in remote organ damage, including ALI. In this study, we investigated whether sivelestat can attenuate neutrophil sequestration in the lung, alleviate ALI, and improve survival in a rat bowel IRI model. ⋯ In a rat model, administration of sivelestat attenuated the effects of bowel IRI induced by supravisceral aortic clamping, and improved the survival rate.

Clinical trials evaluating the use of steroids in septic shock have shown variable outcomes. Our previous studies have implicated human glucocorticoid receptor (hGR) polymorphisms as a possible cause of altered steroid response. To further evaluate this variability, we hypothesized that hGR polymorphisms along with type of steroid influence the functional response. ⋯ SNPs, type of steroid, and concentration range impact the functional response of the hGR. A greater understanding of hGR polymorphisms and steroid response may further elucidate mechanisms explaining the variable response seen with patient treatment.

Hypothermic machine perfusion (HMP) of kidneys is intended to mitigate the deleterious effects of cold storage on organ quality, particularly when the cold ischemic time is prolonged or the donor is otherwise marginal. The use of HMP has remained controversial; however, a number of randomized controlled trials (RCTs) have recently been conducted to clarify its benefits. ⋯ There are few RCT comparing HMP and cold storage of kidneys in deceased donor kidney transplantation. Although these studies are small and heterogeneous in design, HMP appeared to be associated with a reduced incidence of DGF. No difference in the incidence of PNF, graft loss, or patient death at 1 y could be demonstrated.

Operating room time is highly resource intensive, and delays can be a source of lost revenue and surgeon frustration. Methods to decrease these delays are important not only for patient care, but to maximize operating room resource utilization. The purpose of this study was to determine the root cause of operating room delays in a standardized manner to help improve overall operating room efficiency. ⋯ A standardized postoperative debrief tracking system is highly beneficial in identifying and reducing overall operative delays and improving operating room utilization.

Hepatic ischemia-reperfusion (I/R) injury is a serious clinical complication that may compromise liver function because of extensive hepatocyte loss. Therefore, the development of novel and effective therapies for hepatic I/R is critical for the improvement of patient outcome. It has been previously shown that administration of milk fat globule-EGF factor VIII (MFG-E8), a membrane-associated secretory glycoprotein, exerts significant beneficial effects under acute inflammatory conditions through multiple physiological processes associated with tissue remodeling. ⋯ MFG-E8-mediated multiple physiological events may represent an effective therapeutic option in tissue injury following an episode of hepatic I/R.
