Inhibition of Neogenin Dampens Hepatic Ischemia-Reperfusion Injury.
Liver ischemia and reperfusion injury is a common source of significant morbidity and mortality following liver transplantation, hemorrhagic shock, or major hepatic surgery. Based on studies showing a critical role for the neuronal guidance receptor neogenin (Neo1) outside the nervous system in mediating tissue adaption during acute inflammation, we hypothesized that Neo1 enhances hepatic ischemia and reperfusion injury. ⋯ These data provide a unique role for Neo1 in the development of hepatic ischemia and reperfusion injury and identified Neo1 as a potential target to prevent liver dysfunction in the future.

Sepsis-induced myopathy and critical illness myopathy (CIM) are possible causes of muscle weakness in intensive care patients. They have been attributed to muscle membrane dysfunction. The aim of this study was to investigate membrane properties in the early stage of experimental sepsis by evaluating muscle excitability. ⋯ Muscle membrane abnormalities consistent with membrane depolarization and/or sodium channel inactivation occurred within 6 hours of peritonitis induction. This indicates that changes that have been described in established sepsis-induced myopathy and/or CIM start early in the course of sepsis. Muscle excitability testing facilitates evaluation of the time course of these changes.

ReviewALTERATION IN SYNAPTIC JUNCTION PROTEINS FOLLOWING TRAUMATIC BRAIN INJURY.
Extensive research and scientific efforts have been focused on the elucidation of the pathobiology of cellular and axonal damage following traumatic brain injury (TBI). Conversely, few studies have specifically addressed the issue of synaptic dysfunction. ⋯ A Synapse Protein Database on synapse ontology identified 109 domains implicated in synaptic activities and over 5000 proteins, but few of these demonstrated to play a role in the synaptic dysfunction after TBI. These proteins are involved in neuroplasticity and neuromodulation and, most importantly, may be used as novel neuronal markers of TBI for specific intervention.

Although the incidence of acute pancreatitis among children is less than that in adults, the physical and psychosocial impact on children and their families can be overwhelming. Pancreatitis is manifested as pain accompanied by a host of other complex issues. ⋯ Management after discharge from the hospital is often an ongoing stress for these patients and families, and multiple admissions to the intensive care unit may be necessary for feeding and pain complications. Presented in the context of an actual clinical case at a 500-bed tertiary care pediatric hospital, this patient's scenario illustrates the importance of ensuring adequate nutrition, maintaining hydration, providing appropriate pain management, and preventing infection and thromboembolic events.
