The extensive use of major hepatectomy for liver malignancies with cirrhosis increases the risk of posthepatectomy liver failure (PHLF), which is associated with a high frequency of postoperative complications, mortality, and an increased length of hospital stay. Remnant liver volume-to-body weight ratio (RLV-BWR) is more specific than the ratio of RLV-to-total liver volume (RLV-TLV) in predicting postoperative course after major hepatectomy in normal liver. Patients having normal liver with an anticipated RLV-BWR ≤0.5% are at considerable risk for hepatic dysfunction and postoperative mortality. In the present study, the critical value of RLV-BWR after liver resection in cirrhotic liver was investigated. ⋯ RLV-BWR was more specific than RLV-TLV in predicting PHLF after major hepatectomy of cirrhotic liver. Patients with an anticipated RLV-BWR <1.4% are at considerable risk for PHLF.

Septic shock is still related to unacceptably high morbidity and mortality. Microcirculatory alteration has been demonstrated to be one important reason associated with this evolution. Vasoactive drugs are often used to restore adequate arterial pressure and tissue perfusion in septic shock. To define the roles of different drugs, the effects of terlipressin (TP) on the microcirculation of small bowel mesentery in rats with endotoxic shock were evaluated and compared with those of norepinephrine (NE). ⋯ Both TP and NE improved hemodynamic and microcirculatory alterations in rats with endotoxic shock. Compared with NE, TP was more effective in promoting MFI and improving the heterogeneity of small bowel mesentery in rats.

Remote ischemic conditioning enhanced the early recovery of renal function in recipients after kidney transplantation: a randomized controlled trial.
To investigate whether remote ischemic conditioning (RIC) can attenuate ischemic reperfusion injury (IRI) in recipients after kidney transplantation using donation after cardiac death. ⋯ RIC enhanced the early recovery of renal function in recipients after kidney transplantation. Our results provide a novel potential approach to attenuate transplantation-associated IRI.

We recently reported a grading system for surgical complications. This system proved to have a high sensitivity for recording minor but meaningful complications prolonging hospital stay in patients after colorectal surgery. We aimed to prospectively validate the complication grading system in a general surgery department over 1 year. ⋯ This system of grading surgical complications permits standardized reporting of surgical morbidity according to the severity of impact. Prospective validation of this system supports its use in a general surgery setting as a tool for surgical outcome assessment and quality assurance.

Although the relationship between psychoactive substance use and injury is known, evidence remains conflicting on the impact of substance use on clinical outcomes after injury. We hypothesized that preinjury substance use would negatively impact clinical outcomes. ⋯ Females and those aged >45 y are less likely to receive BASs and UDSs. Differential screening that is biased may place patients at risk for receiving inadequate care.
