Several studies evaluating simulation training in intensive care unit (ICU) physicians have demonstrated improvement in leadership and management skills. No study to date has evaluated whether such training is useful in established ICU advanced practitioners (APs). We hypothesized that human patient simulator-based training would improve surgical ICU APs' skills at managing medical crises. ⋯ Human patient simulator training in established surgical ICU APs improves leadership, teamwork, and self-confidence skills in managing medical emergencies. Such a validated curriculum may be useful as an AP continuing education resource.

Resuscitation of hemorrhagic shock with isotonic crystalloids has been shown to activate polymorphonuclear neutrophils (PMNs). Although hypertonic saline (HTS) can reduce PMN activation and interactions with endothelial cells (EC) in systemic microvascular beds, no data exist demonstrating that the same occurs in the unique blood-brain barrier microcirculation. We hypothesized that resuscitation of hemorrhagic shock with HTS would blunt brain in vivo PMN-EC interactions. ⋯ In contradistinction to studies evaluating the systemic microcirculation, HTS may activate PMN-EC crosstalk in the blood-brain microcirculation. Further studies are needed to analyze whether this effect is due to the unique nature of the blood-brain interface.

Plasma gelsolin depletion has been associated with poor outcome of critically ill patients. However, there is a paucity of data available on circulating plasma gelsolin concentration in traumatic brain injury (TBI). Thus, we sought to investigate change in plasma gelsolin level after TBI and to evaluate its relation with disease outcome. ⋯ Decreased plasma gelsolin level is associated with GCS scores and an independent prognostic marker of mortality after TBI. Reversing plasma gelsolin deficiency may be an effective treatment for TBI.

Use of cephalomedullary devices for pertrochanteric fractures has been associated with complications of cutout, fracture distal to the tip of the implant, infection, and hardware failure. The goal of recent design changes (a trapezoidal shape of the proximal device, with interdigitation of the cephalocervical screws) in cephalomedullary nails was to improve fracture fixation and stability of pertrochanteric fractures. This is a retrospective review of the first 127 surgeries using this new cephalomedullary nail to review early complications seen with this device. ⋯ In our study population, we found this newer cephalomedullary device had complications similar to those reported with devices in previous studies.
