Review Meta Analysis
The prognostic value of serum neuron-specific enolase in traumatic brain injury: systematic review and meta-analysis.
Several studies have suggested that neuron-specific enolase (NSE) in serum may be a biomarker of traumatic brain injury. However, whether serum NSE levels correlate with outcomes remains unclear. The purpose of this review was to evaluate the prognostic value of serum NSE protein after traumatic brain injury. ⋯ Mortality and unfavorable outcome were significantly associated with greater NSE concentrations. In addition, NSE has moderate discriminatory ability to predict mortality and neurological outcome in TBI patients. The optimal discrimination cutoff values and optimal sampling time remain uncertain because of significant variations between studies.

Review Meta AnalysisValue of Repeat Head Computed Tomography after Traumatic Brain Injury: Systematic Review and Meta-Analysis.
Diagnosis and management of traumatic brain injury (TBI) is crucial to improve patient outcomes. While initial head computed tomography (CT) scan is the optimum tool for quick and accurate detection of intracranial hemorrhage, the guidelines on use of repeat CT differ among institutions. Three systematic reviews have been conducted on a similar topic; none have performed a comprehensive meta-analysis of all studies. ⋯ In a subgroup analysis of mild TBI patients (Glasgow Coma Scale score 13 to 15), five prospective and nine retrospective studies reported on change in management following repeat CT with the pooled proportion across prospective studies at 2.3% (95% CI 0.3-6.3) and across retrospective studies at 3.9% (95% CI 2.3-5.7), respectively. The evidence suggests that repeat CT in patients with TBI results in a change in management for only a minority of patients. Better designed studies are needed to address the issue of the value of repeat CT in the management of TBI.

Meta AnalysisModerate hypothermia treatment in adult patients with severe traumatic brain injury: a meta-analysis.
To evaluate the effect of moderate hypothermia treatment (MHT) in severe traumatic brain injury (sTBI) compared to normothermia management. ⋯ MHT may be effective in reducing death and unfavourable clinical neurological outcomes, but this finding is not statistically significant, except for decreasing the mortality in Asian patients.

Review Meta AnalysisTraumatic Brain Injury: Methodological Approaches to Estimate Health- and Economic Outcomes.
The effort to standardize the methodology and adherence to recommended principles for all economic evaluations has been emphasized in medical literature. The objective of this review is to examine whether economic evaluations in traumatic brain injury (TBI) research have been compliant with existing guidelines. Medline search was performed between January 1, 1995 and August 11, 2012. ⋯ On average, about six of the 10 criteria were followed in these publications, and only two articles met all 10 criteria. These findings call for an increased awareness of the methodological standards that should be followed by investigators both in performance of economic evaluation and in reviews of evaluation reports prior to publication. The results also suggest that all economic evaluations should be made by following the guidelines within a conceptual framework, in order to facilitate evidence-based practices in the field of TBI.

Review Meta Analysis
Pharmacological perioperative brain neuroprotection: a qualitative review of randomized clinical trials.
Perioperative cerebral damage may be associated with surgery and anaesthesia. Pharmacological perioperative neuroprotection is associated with conflicting results. In this qualitative review of randomized controlled clinical trials on perioperative pharmacological brain neuroprotection, we report the effects of tested therapies on new postoperative neurological deficit, postoperative cognitive decline (POCD), and mortality rate. ⋯ None of the tested drugs was associated with a reduction in mortality rate. Drugs with various mechanisms of action have been tested over time; current evidence suggests that pharmacological brain neuroprotection might reduce the incidence of new postoperative neurological deficits and POCD, while no benefits on perioperative mortality are described. Of importance from this review is the need for shared methodological approach when clinical studies on pharmacological neuroprotection are designed.
