Comparative Study
Fibrinogen and prothrombin complex concentrate in trauma coagulopathy.
Coagulopathy after injury contributes to hemorrhage and death. Treatment with specific coagulation factors could decrease hemorrhage and mortality. Our aim was to compare fibrinogen and prothrombin complex concentrate (PCC) in a rabbit model of hemorrhagic shock. ⋯ In a rabbit model, PCC did not have a significant effect on blood loss. Fibrinogen increased blood loss and fluid requirements.

Nuclear factor-E2-related factor 2 (Nrf2)-mediated antioxidant response is the main protective system of graft-liver against ischemia-reperfusion injury after liver transplantation. Propofol is considered to confer protective effects on different organs; thus, we explored the possibility that whether propofol could attenuate graft-liver injury in a rat autologous orthotopic liver transplantation (AOLT) model and mechanisms were associated with activation of Nrf2 pathway. ⋯ Protective effects of propofol against liver transplantation-induced graft-liver injury may be related with Keap1-Nrf2 signal pathway activation.

FTY720, a sphingosine-1-phosphate (S1P) receptor agonist, possesses potent anti-inflammation capacity. We evaluated the therapeutic potentials of FTY720 against testicular injury induced by testicular torsion and/or detorsion (T/D). ⋯ FTY720 significantly mitigated testicular injury induced by testicular T/D. The mechanisms may involve activating the S1P receptors.

Assessment of interpersonal and psychosocial competencies during end-of-life care training is essential. This study reports the relationship between simulation-based end-of-life care Objective Structured Clinical Examination ratings and communication skills, trust, and self-assessed empathy along with the perceptions of students regarding their training experiences. ⋯ We found that simulation-based OSCE training in palliative and end-of-life care can be effectively conducted during a surgery clerkship. Moreover, the standardized patient encounters combined with the formal assessment of communication skills, physician trust, and empathy provide feedback to students at an early phase of their professional life. The positive and appreciative comments of students regarding the opportunity to practice difficult patient conversations suggest that attention to these professional characteristics and skills is a valued element of clinical training and conceivably a step toward better patient outcomes and satisfaction.

Our purpose was to analyze modern major vascular injury (MVI) patterns in pediatric trauma, interventions performed, and outcomes at a level 1 trauma center. ⋯ MVI in children more commonly results from firearm-related injury. The mortality rate associated with MVI is profoundly higher than that of the overall pediatric trauma population. These findings underscore the major public health concern of firearm-related injury in children.
