Recently, several randomized controlled trials (RCT) investigating the effectiveness of decompressive craniectomy in the context of neurocritical illnesses have been completed. Thus, a meta-analysis to update the current evidence regarding the effects of decompressive craniectomy is necessary. We searched PUBMED, EMBASE and the Cochrane Central Register of Controlled Trials. ⋯ Decompressive craniectomy significantly reduced the risk of death for patients suffering malignant MCAI (risk ratio [RR] 0.46, 95% confidence interval [CI]: 0.36-0.59, P<0.00001) in comparison with no reduction in the risk of death for patients with severe TBI (RR: 0.83, 95% CI: 0.48-1.42, P=0.49). However, there was no significant difference in the composite risk of death or dependence at the final follow-up between the decompressive craniectomy group and the conservative treatment group for either malignant MCAI or severe TBI. The present meta-analysis indicates that decompressive craniectomy can significantly reduce the risk of death for patients with malignant MCAI, although no evidence demonstrates that decompressive craniectomy is associated with a reduced risk of death or dependence for TBI patients.

There is a paucity of accurate and reliable biomarkers to detect traumatic brain injury, grade its severity, and model post-traumatic brain injury (TBI) recovery. This gap could be addressed via advances in brain mapping which define injury signatures and enable tracking of post-injury trajectories at the individual level. ⋯ Inferences from mapping represent unique endophenotypes which have the potential to transform classification and treatment of patients with TBI. Limitations of these methods, as well as future research directions, are highlighted.

ReviewSocial dysfunction after pediatric traumatic brain injury: A translational perspective.
Social dysfunction is common after traumatic brain injury (TBI), contributing to reduced quality of life for survivors. Factors which influence the development or persistence of social deficits after injury remain poorly understood, particularly in the context of ongoing brain maturation during childhood and adolescence. Aberrant social interactions have recently been modeled in adult and juvenile rodents after experimental TBI, providing an opportunity to gain new insights into the underlying neurobiology of these behaviors. ⋯ Modulators of social outcomes are discussed, including injury-related and environmental risk and resilience factors. Disruption of social brain network connectivity and aberrant neuroendocrine function are identified as potential mechanisms of social impairments after pediatric TBI. Throughout, we highlight the overlap and disparities between outcome measures and findings from clinical and experimental approaches, and explore the translational potential of future research to prevent or ameliorate social dysfunction after childhood TBI.

Optimal anticoagulation therapy (AT) in patients with traumatic brain injury (TBI) is a challenging task and proper management is strongly correlated with clinical outcomes. Only limited data are available on AT after TBI and practical decision making is based on the opinion of experts. This review sought to critically assess different therapeutic options using AT and antiplatelet agents in the perioperative period after TBI. ⋯ Patients with preinjury AT with TBI require emergent neurosurgical treatment and they are also at high risk of developing thromboembolic complications or hematoma expansion. New oral anticoagulants offer a lower incidence of intracranial hemorrhage compared with warfarin. The rate of intracranial hemorrhage during new oral anticoagulants or heparin therapy is significantly lower than that with vitamin K antagonists.
