Necrotizing soft tissue infections (NSTIs) represent a devastating spectrum of disease with high case mortality and resource intensive care. Treatment consists of wide surgical debridement and often prolonged periods of intensive care unit care. Major complications are common. The severity of the disease and the aggressive treatment requirements put survivors at risk for significant long-term sequelae related to the trauma of both disease and treatment. Information about the postdischarge impact of NSTIs on survivors is extremely limited. Qualitative approaches are typically used to explore new phenomena and to capture individuals' thoughts, feelings, or interpretations of meaning and process. Therefore, qualitative methods are ideally suited for hypothesis generation to guide future quantitative study and ensure measured outcomes are patient-centered. ⋯ Patient's reported quality of life was significantly affected by their disease and recovery. The results demonstrate that many outcomes of importance for patients are not easily assessed by traditional measures of outcomes. This work illustrates the multidimensional nature of recovery from critical illness, and shows that it represents a massive transition period in the lives of survivors that affects the patient, their family, and the patient's ability to interact with society. Interviews with survivors ensure that the patient voice is heard before developing tools to assess long-term outcomes.

Blood products containing leukocytes have been associated with negative immunomodulatory and infectious effects. Transfusion-related acute lung injury is partially explained by leucocyte agglutination. The Food and Drug Administration has therefore recommended leukoreduction strategies for blood product transfusion. Our institution has been using leukocyte-reduced blood via filtration for neonates on Extracorporeal Membrane Oxygenation (ECMO). We hypothesized that the use of leukocyte-reduced blood would decrease mortality and morbidity of neonatal ECMO patients. ⋯ Blood transfusion requirement has diminished in newborns undergoing ECMO at our institution. Transfusion of non leukocyte-reduced blood is associated with an increase in mortality whereas transfusion of leukocyte-reduced blood provided no benefit with a trend toward increased mortality. Further research is recommended to understand these trends.

We have shown previously that vagal nerve stimulation (VNS) protects against burn-induced acute lung injury (ALI). Although the mobilization and activation of immune cells is central to tissue injury caused by the systemic inflammatory response, the specific inflammatory cell populations that are modulated by VNS have yet to be fully defined. The purpose of this study was to assess whether VNS alters inflammatory cell recruitment to the lung after severe burn injury. ⋯ VNS is an effective method to limit pulmonary DC recruitment to the lung and prevent ALI after burn injury. Identifying strategies to limit inflammatory cell recruitment to the lung may have clinical utility in preventing ALI in severely burned patients.

Review Meta Analysis Comparative Study
Pancreaticogastrostomy versus pancreaticojejunostomy.
It has long been debated whether pancreaticogastrostomy (PG) or pancreaticojejunostomy (PJ) is the better choice for reconstruction after pancreaticoduodenectomy. The purpose of this study is to evaluate the two techniques. ⋯ The evidence from RCTs suggests that PG technique is associated with a lower rate of postoperative pancreatic fistula and intra-abdominal fluid collection than PJ.

Augmenter of Liver Regeneration (ALR), a protein synthesized in the liver is suggested to be protective against oxidative stress-induced cell death. Hepatic ischemia-reperfusion (I/R) injury is triggered by reactive oxygen species. Here, we tested the hypothesis that ALR attenuates hepatic I/R injury in vivo. ⋯ Our in vivo data show that ALR has a therapeutic potential against postischemic liver injury. As a mechanism, we suggest a direct protective effect of ALR on apoptotic and necrotic death of hepatocytes and an attenuation of inflammatory cell influx into the postischemic tissue.
