To conduct a meta-analysis to determine whether progesterone, compared with placebo or no treatment, influences mortality and neurologic outcome in traumatic brain injury (TBI). ⋯ This study is the largest meta-analysis conducted to date to determine whether progesterone is effective in the treatment of TBI. The findings indicate that progesterone treatment does not decrease mortality or improve neurologic outcome in patients with TBI.

ReviewRelationship between trauma-induced coagulopathy and progressive hemorrhagic injury in patients with traumatic brain injury.
Progressive hemorrhagic injury (PHI) can be divided into coagulopathy-related PHI and normal coagu- lation PHI. Coagulation disorders after traumatic brain injuries can be included in trauma-induced coagulopathy (TIC). ⋯ The main mechanism in the relation of TIC to PHI is hypocoagulability. We also reviewed some coagulopathy parameters and proposed some possible risk factors, predictors and therapies.

Longitudinal Diffusion Tensor Imaging Detects Recovery of Fractional Anisotropy Within Traumatic Axonal Injury Lesions.
Traumatic axonal injury (TAI) may be reversible, yet there are currently no clinical imaging tools to detect axonal recovery in patients with traumatic brain injury (TBI). We used diffusion tensor imaging (DTI) to characterize serial changes in fractional anisotropy (FA) within TAI lesions of the corpus callosum (CC). We hypothesized that recovery of FA within a TAI lesion correlates with better functional outcome. ⋯ In this retrospective longitudinal study, we provide initial evidence that FA can recover within TAI lesions. However, FA recovery did not correlate with improved functional outcomes. Prospective histopathological and clinical studies are needed to further elucidate whether lesional FA recovery indicates axonal healing and has prognostic significance.

Randomized Controlled Trial Comparative Study
Intracranial Pressure During Pressure Control and Pressure-Regulated Volume Control Ventilation in Patients with Traumatic Brain Injury: A Randomized Crossover trial.
Mechanical ventilation with control of partial arterial CO2 pressures (PaCO2) is used to treat or stabilize intracranial pressure (ICP) in patients with traumatic brain injury (TBI). Pressure-regulated volume control (PRVC) is a ventilator mode where inspiratory pressures are automatically adjusted to deliver the patient a pre-set stable tidal volume (TV). This may result in a more stable PaCO2 and thus a more stable ICP compared with conventional pressure control (PC) ventilation. The aim of this study was to compare PC and PRVC ventilation in TBI patients with respect to ICP and PaCO2. ⋯ Mean ICP and PaCO2 were similar for PC and PRVC ventilation in TBI patients, but PRVC ventilation resulted in less fluctuation in both ICP and PaCO2. We cannot exclude that the two ventilatory modes would have impact on ICP in patients with higher ICP values; however, the similar PaCO2 observations argue against this.

Whether anemia complicating traumatic brain injury (TBI) has an impact on patient outcomes is controversial; therefore, recommendations for blood transfusions for such patients are inconsistent. We hypothesized that patient outcome after TBI would be worse in patients with lower hemoglobin levels. ⋯ Patient outcome after TBI is worse in patients with lower hemoglobin. Initial hemoglobin and lowest hemoglobin after admission are independently associated with poor outcome. Our data support consideration of blood transfusion when hemoglobin is ≤8 g/dl.
