Randomized Controlled TrialCerebrospinal Fluid Biomarkers in Human Spinal Cord Injury from a Phase II Minocycline Trial.
Inflammatory changes after spinal cord injury (SCI) have been reported in animal models, but human studies are relatively limited. We examined cerebrospinal fluid (CSF) collected from subjects enrolled in a phase II placebo-controlled trial of minocycline for evidence of inflammatory and structural changes after acute human SCI. CSF was collected from 29 subjects every 6 h for 7 days and investigated for eight molecules. ⋯ Higher cumulative levels of IL-1β, MMP-9, and CXCL10 exhibited moderate, but significant, correlation with worse motor recovery at 12 months. Only HO-1 and NfH appeared to vary with minocycline treatment; HO-1 lacked a later peak compared to placebo-treated subjects while NfH did not manifest its early peak with treatment. These analyses of CSF biomarkers imply a pathophysiological role for particular molecules and suggest mechanistic targets for minocycline in human traumatic SCI.

Randomized Controlled Trial Multicenter StudyThe Effect of Goreisan on the Prevention of Chronic Subdural Hematoma Recurrence: Multi-Center Randomized Controlled Study.
The relatively high rate of post-operative recurrence in the treatment of chronic subdural hematoma (CSDH) is a significant problem. Goreisan is an herbal medicine that exhibits a hydragogue effect by inhibiting the expression of aquaporins, and its efficacy in preventing post-operative CSDH recurrence has been suggested by several case trials. This multi-center prospective randomized controlled trial was performed to investigate the preventative effect of goreisan on post-operative CSDH recurrence. ⋯ The recurrence rates considering patients of all ages and patients under 75 years old were relatively low in the goreisan group but without a significant difference. The hematoma volume reduction rates showed no significant difference. Based on the results of the present study, a larger-scale study including more cases is necessary in future to confirm the efficacy of goreisan.

Randomized Controlled Trial Multicenter StudyRho Inhibitor VX-210 in Acute Traumatic Subaxial Cervical Spinal Cord Injury: Design of the SPinal Cord Injury Rho INhibition InvestiGation (SPRING) Clinical Trial.
Traumatic spinal cord injury (SCI) is associated with a lifetime of disability stemming from loss of motor, sensory, and autonomic functions; these losses, along with increased comorbid sequelae, negatively impact health outcomes and quality of life. Early decompression surgery post-SCI can enhance patient outcomes, but does not directly facilitate neural repair and regeneration. Currently, there are no U. ⋯ A subset of patients with acute traumatic cervical SCI is currently being enrolled in the United States and Canada. Medical, neurological, and functional changes are evaluated at 6 weeks and at 3, 6, and 12 months after VX-210 administration. Efficacy will be assessed by the primary outcome measure, change in upper extremity motor score at 6 months post-treatment, and by secondary outcomes that include question-based and task-based evaluations of functional recovery.

Randomized Controlled Trial Multicenter StudyCause and timing of death and sub-group differential effects of erythropoietin in the EPO-TBI study.
The EPO-TBI study randomized 606 patients with moderate or severe traumatic brain injury (TBI) to be treated with weekly epoetin alfa (EPO) or placebo. Six month mortality was lower in EPO treated patients in an analysis adjusting for TBI severity. Knowledge of possible differential effects by TBI injury subtype and acute neurosurgical treatment as well as timing and cause of death (COD) will facilitate the design of future interventional TBI trials. ⋯ However, EPO appeared more effective in patients with an injury type not requiring a neurosurgical operation prior to intensive care unit (ICU) admission (odds ratio [OR] 0.29, 95% confidence interval [CI] 0.14-0.61, p = 0.001, p for interaction = 0.003) and in this subgroup, fewer patients died of cerebral causes in the EPO than in the placebo group (5% compared with 14%, p = 0.03). In conclusion, most TBI deaths were from cerebral causes that occurred during the first 2 weeks, and were related to withdrawal of care. EPO appeared to specifically reduce cerebral deaths in the important subgroup of patients with a diffuse type of injury not requiring a neurosurgical intervention prior to randomization.

Randomized Controlled Trial Multicenter StudyA Method of Managing Severe Traumatic Brain Injury in the Absence of Intracranial Pressure Monitoring: the ICE Protocol.
The imaging and clinical examination (ICE) algorithm used in the Benchmark Evidence from South American Trials: Treatment of Intracranial Pressure (BEST TRIP) randomized controlled trial is the only prospectively investigated clinical protocol for traumatic brain injury management without intracranial pressure (ICP) monitoring. As the default literature standard, it warrants careful evaluation. We present the ICE protocol in detail and analyze the demographics, outcome, treatment intensity, frequency of intervention usage, and related adverse events in the ICE-protocol cohort. ⋯ Adverse event incidence was low and comparable to the BEST TRIP monitored group. Although this protocol should produce similar/acceptable results under circumstances comparable to those in the trial, influences such as longer pre-hospital times and non-specialist transport personnel, plus an intensive care unit model of aggressive physician-intensive care by small groups of neurotrauma-focused intensivists, which differs from most high-resource models, support caution in expecting the same results in dissimilar settings. Finally, this protocol's ICP-titration approach to suspected intracranial hypertension (vs. crisis management for monitored ICP) warrants further study.
