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.

Objective measures for preoperative risk assessment are needed to inform surgical risk stratification. Previous studies using preoperative imaging have shown that the psoas muscle is a significant predictor of postoperative outcomes. Because psoas measurements are not always available, additional trunk muscles should be identified as alternative measures of risk assessment. Our research assessed the relationship between paraspinous muscle area, psoas muscle area, and surgical outcomes. ⋯ Paraspinous muscle area correlates with psoas muscle area, and larger paraspinous muscle area is associated with lower mortality rates after surgery. This suggests that the paraspinous muscle may be an alternative to the psoas muscle in the context of objective measures of risk stratification.

As work hour restrictions increasingly limit some operative experiences, personalized evaluative methods are needed. We prospectively assessed the value of cumulative sum (Cusum) to measure proficiency with percutaneous endoscopic gastrostomy (PEG) among surgical trainees. ⋯ Although lacking the granular insight of expert evaluations, Cusum analysis is more sensitive to relapses of subproficient performance. Adding Cusum analysis to expert evaluations can provide longitudinal, formative feedback and promote efficient redistribution of operative experiences.

Surgical burden is a large and neglected global health problem in low- and middle-income countries. With the increasing trauma burden, the goal of this study was to evaluate the trauma capacity of hospitals in the central plateau of Haiti. ⋯ Trauma capacity in the central plateau of Haiti is limited. There is a great need for more personnel, trauma training at all staff levels, emergency care guidelines, trauma registries, and imaging equipment and training, specifically in ultrasonography. To accomplish this, coordination is needed between the Haitian government and local and international nongovernmental organizations.

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.
