Randomized Controlled Trial
Fibrocaps for surgical hemostasis: two randomized, controlled phase II trials.
Fibrocaps, a ready-to-use, dry-powder fibrin sealant containing human plasma-derived thrombin and fibrinogen, is being developed as an adjunct for surgical hemostasis. ⋯ Fibrocaps had good safety and efficacy profiles, supporting continuing clinical development as a novel fibrin sealant.

There is an accelerated effort to reduce hospital readmissions despite minimal data detailing risk factors associated with this outcome. ⋯ Postoperative complications demonstrated stronger association with readmission than patient factors. Focused analysis of higher risk procedures may provide insight into strategies for risk reduction.

Brain Trauma Foundation (BTF) guidelines recommend intracranial pressure (ICP) monitoring for traumatic brain injury (TBI) patients with a Glasgow Coma Scale score of 8 or less with an abnormal head computed tomography, or a normal head computed tomography scan with systolic blood pressure ≤90 mm Hg, posturing, or in patients of age ≥40. The benefits of these guidelines on outcome remain unproven. We hypothesized that adherence to BTF guidelines for ICP monitoring does not improve outcomes in patients with TBI. ⋯ Our data suggest that there is a subset of patients meeting BTF criteria for ICP monitoring that do well without ICP monitoring. This finding should provoke reevaluation of the indication and utility of ICP monitoring in TBI patients.

Lipopolysaccharide (LPS) has a deleterious effect on several organs, including the liver, and eventually leads to endotoxic shock and death. LPS-induced hepatotoxicity is characterized by disturbed intracellular redox balance and excessive reactive oxygen species (ROS) accumulation, leading to liver injury. We have shown that treatment with suberoylanilide hydroxamic acid (SAHA), a histone deacetylase inhibitor, improves survival in a murine model of LPS-induced shock, but the protective effect of SAHA against liver damage remains unknown. The goal of this study was to investigate the mechanism underlying SAHA action in murine livers. ⋯ Our data indicate, for the first time, that SAHA is capable of alleviating LPS-induced hepatotoxicity and suggest that a blockade of the upstream events required for apoptosis signal-regulating kinase-1 action may serve as a new therapeutic option in the treatment of LPS-induced inflammatory conditions.

Systemic inflammation and oxidative stress are crucial in mediating blood-brain barrier (BBB) integrity loss during sepsis. Simvastatin possess potent anti-inflammation and antioxidation capacity. We sought to elucidate whether an acute bolus of simvastatin could mitigate BBB integrity loss in a rodent model of polymicrobial sepsis. ⋯ Simvastatin mitigates BBB integrity loss in a rodent model of polymicrobial sepsis.
