Case ReportsFentanyl Overdose Caused by Malfunction of SynchroMed II Intrathecal Pump: Two Case Reports.
Intrathecal drug delivery systems (intrathecal pumps) are used to treat patients with chronic refractory pain syndromes and spasticity. The objective of our case report was to demonstrate that intrathecal pump malfunction can lead to intrathecal overdosing of drugs. ⋯ We present 2 cases of intrathecal pump malfunction, which most likely led to overinfusion of fentanyl intrathecally. To reduce the risk of this complication, particular attention should be paid to drug reservoir volume discrepancies and overdose symptoms reported by patients.

ReviewWhen Cardiac Failure, Kidney Dysfunction, and Kidney Injury Intersect in Acute Conditions: The Case of Cardiorenal Syndrome.
To review and describe diagnostic and prognostic value of biomarkers of renal function and renal injury in the cardiorenal syndrome complicating acutely decompensated heart failure. ⋯ Biomarkers reflecting renal function and injury are likely to better phenotype subgroups of patients with cardiorenal syndrome and to provide unique prognostic information. Future studies are needed relative to strategies using such biomarkers to guide care of affected patients.

Observational Study
Assessing the bowel function of critically ill children: a pilot study.
To describe the bowel function of critically ill children. ⋯ Critically unwell children needing more than 24 hours of intensive care have a state of non-defecation for most of the time, with formed stools being rare. Further observational studies will better define bowel function in critically unwell children.

Caveolae are a nexus for protective signaling. Trafficking of caveolin to mitochondria is essential for adaptation to cellular stress though the trafficking mechanisms remain unknown. The authors hypothesized that G protein-coupled receptor/inhibitory G protein (Gi) activation leads to caveolin trafficking to mitochondria. ⋯ Gi proteins are involved in trafficking caveolin to mitochondria to enhance stress resistance. Agents that target Gi activation and caveolin trafficking may be viable cardioprotective agents.

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.
