Meta AnalysisA systematic review and meta-analysis of hypothermia in experimental traumatic brain injury: why have promising animal studies not been replicated in pragmatic clinical trials?
Therapeutic hypothermia was a mainstay of severe traumatic brain injury (TBI) management for half a century. Recent trials have suggested that its effect on long-term functional outcome is neutral or negative, despite apparently promising pre-clinical data. Systematic review and meta-analysis is a useful tool to collate experimental data and investigate the basis of its conclusions. ⋯ Therapeutic hypothermia appears to be an efficacious treatment in experimental TBI, which differs from the clinical evidence. The pre-clinical literature showed limitations in quality and design and these both appeared to affect neurobehavioral experiment outcome. These should be acknowledged when designing and interpreting pre-clinical TBI studies in the future.

Meta AnalysisPharmacological and Non-pharmacological Interventions for Depression after Moderate to Severe Traumatic Brain Injury: a Systematic Review and Meta-analysis.
The objective of this study was to systematically review the literature and perform a meta-analysis of randomized controlled trials (RCTs) on the effectiveness of pharmacological and non-pharmacological interventions for depression in patients with moderate-to-severe traumatic brain injury. Databases searched were: Embase, PubMed, PsycInfo, Cochrane Central, Web of Science, and Google Scholar. Depression score on a self-report questionnaire was the outcome measure. ⋯ The SMD of low-quality studies did not differ significantly from moderate- and high-quality studies (ΔSMD: 0.321, p = 0.050). Although RCTs targeting interventions for depression after TBI are scarce, both pharmacological and non-pharmacological interventions appear to be effective in treating depressive symptoms/depression after moderate-to-severe TBI. There is a need for high-quality RCTs in which the add-on effects of pharmacological and non-pharmacological interventions are investigated.

Meta AnalysisPrevalence of Anterior Pituitary Dysfunction 12 months or more following Traumatic Brain Injury in Adults - A Systematic review and Meta-analysis.
The objective of this study is to systematically review clinical studies that have reported on the prevalence of chronic post-traumatic brain injury anterior pituitary dysfunction (PTPD) 12 months or more following traumatic brain injury (TBI). We searched Medline, Embase, and PubMed up to April 2017 and consulted bibliographies of narrative reviews. We included cohort, case-control, and cross-sectional studies enrolling at least five adults with primary TBI in whom at least one anterior pituitary axis was assessed at least 12 months following TBI. ⋯ Studies with a higher proportion of participants with mild TBI had a lower prevalence of PTPD. Our results show that approximately one-third of TBI sufferers have persistent anterior pituitary dysfunction 12 months or more following trauma. Future research on PTPD should differentiate between mild and moderate/severe TBI.

Meta AnalysisPosttraumatic stress disorder after civilian traumatic brain injury: a systematic review and meta-analysis of prevalence rates.
Post-traumatic stress disorder (PTSD) is a commonly diagnosed psychiatric disorder following traumatic brain injury (TBI). Much research on PTSD and TBI has focused on military conflict settings. Less is known about PTSD in civilian TBI. ⋯ Although most studies that compared participants with TBI with trauma patients and healthy controls found no difference in prevalence rates of PTSD, a meta-analysis across studies revealed a higher prevalence of PTSD in patients with TBI (odds ratio [OR]: 1.73, 95% CI: 1.21-2.47). This review highlights variability between studies and emphasizes the need for higher-quality studies. Further research is warranted to determine risk factors for the development of PTSD after TBI.

Meta AnalysisImpact of Early (<24 h) Surgical Decompression on Neurological Recovery in Thoracic Spinal Cord Injury: A Meta-Analysis.
The impact of surgical timing in neurological recovery in thoracic and thoracolumbar traumatic spinal cord injury (tSCI) is still a subject of discussion. While in cervical tSCI one may expect a beneficial effect of early intervention within 24 h, especially in complete cases, this has not yet been demonstrated clearly for thoracic tSCI. This study addresses neurological improvement after early and late surgery for thoracic and thoracolumbar tSCI. ⋯ In the qualitative analysis, six of seven studies, which investigated the effect of surgical timing, observed a significant effect of early surgery on at least one ASIA grade improvement. Quantitative analysis in 948 patients with thoracic and thoracolumbar tSCI data, however, did not reveal a significant increase in odds of ≥1 ASIA grade recovery in early surgery (66.8% [95% confidence interval (CI): 45.0-87.8%] compared with late surgery (48.9% [95% CI: 25.1-70.7%; odds ratio (OR) 2.2 (95% CI: 0.6-14.0]). This study did not observe a significant beneficial effect of surgical decompression within 24 h in patients with thoracic and thoracolumbar tSCI.
