Patients with colorectal cancer and peritoneal carcinomatosis (CRC/PC) may benefit from cytoreductive surgery and heated intraperitoneal chemotherapy (CRS/HIPEC). Nutritional support is frequently required for patients after CRS/HIPEC. It remains unclear if placement of feeding access is of benefit in regard to improving postoperative nutrition in this patient population. ⋯ Significant nutritional loss is common after CRS/HIPEC for patients with CRC/PC. Feeding tube placement does not prevent this and appears to be related to higher readmission rates and longer length of stay.

Sepsis is a life-threatening acute inflammatory condition associated with metabolic complications. Accumulation of free fatty acids (FFAs) induces inflammation and causes lipotoxic effects in the liver. Because fatty acid metabolism plays a role in the inflammatory response, we hypothesized that the administration of C75, a fatty acid synthase inhibitor, could alleviate the injury caused by sepsis. ⋯ C75 effectively lowered FFA accumulation in the liver, which was associated with inhibition of inflammation and organ injury as well as improvement in survival rate after CLP. Thus, inhibition of FFA by C75 could ameliorate the hepatic dysfunction seen in sepsis.

Comparative Study
Liquid plasma use during "super" massive transfusion protocol.
A massive transfusion protocol (MTP) presents a logistical challenge for most blood banks and trauma centers. We compare the ratio of packed red blood cells (PRBC) and plasma transfused over serial time points in those requiring MTP (10-30 U PRBC/24 h) to those requiring "super" MTP (S-MTP; >30 U PRBC/24 h) and test the hypothesis that changes in allocation of blood products with use of readily transfusable liquid plasma (LP) improves the ratio of PRBC and plasma during S-MTP. ⋯ Within the first hour of transfusion, units of PRBC transfused positively correlated with PRBC:plasma, and patients receiving S-MTP had higher PRBC:plasma than those receiving MTP. Changes in our institution's MTP protocol to include LP improved the early PRBC:plasma transfused in patients requiring S-MTP.

Pediatric patients who undergo liver transplantation are at higher risk of developing vascular complications when compared to adult liver transplant recipients. The consequences of hepatic artery thrombosis (HAT) or portal vein thrombosis (PVT) can cause significant morbidity and mortality. We examined pediatric liver transplant recipients who developed vascular thrombosis and the presence of thrombophilia. ⋯ All pediatric liver transplant recipients who developed any vascular thrombosis were also found to have thrombophilia. Recipients who were smaller in size were at significantly higher risk of developing vascular thrombosis. Lower weight recipients with thrombophilia may benefit from arterial reconstruction with a conduit to decrease the risk of vascular thrombosis.

Lipopolysaccharide/d-galactosamine (LPS/GalN)-induced hepatic injury is an experimental model of fulminant hepatic failure in which tumor necrosis factor alpha (TNF-α) plays a pivotal role. Moreover, it was reported from our laboratory that interleukin (IL) 17A enhanced production of TNF-α by the Kupffer cell. ⋯ IL-17A is a key regulator in hepatic injury caused by neutrophil-induced inflammatory responses after LPS/GalN injection.
