Randomized Controlled Trial
Phase I randomized clinical trial of N-acetylcysteine in combination with an adjuvant probenecid for treatment of severe traumatic brain injury in children.
There are no therapies shown to improve outcome after severe traumatic brain injury (TBI) in humans, a leading cause of morbidity and mortality. We sought to verify brain exposure of the systemically administered antioxidant N-acetylcysteine (NAC) and the synergistic adjuvant probenecid, and identify adverse effects of this drug combination after severe TBI in children. ⋯ Treatment resulted in detectable concentrations of NAC and probenecid in CSF and was not associated with undesirable effects after TBI in children.

Randomized Controlled Trial Multicenter StudyComputerized working memory training for children with moderate to severe traumatic brain injury: a double-blind, randomized, placebo-controlled trial.
Pediatric traumatic brain injury (TBI) places children at risk for deficits in working memory (WM; comprising a central executive [CE], and two storage systems: phonological loop [PL] and visuospatial sketchpad [VSSP]), which is strongly related to attention and academic skills in childhood. This study aimed to examine whether different components of WM can be improved following adaptive WM training (Cogmed) and whether improvements in WM generalize to other cognitive (attention) and academic skills (reading and mathematics) in children with TBI. Twenty-seven children with moderate to severe TBI were randomized to adaptive (Cogmed; n = 13) or non-adaptive training (active placebo; n = 14) and evaluated at baseline, post-training, and 3-months follow-up. ⋯ No gains were found on tests of attention. Adaptive training resulted in significantly greater gains on select academic skills (reading, but not mathematics): reading comprehension pre-post-training (ITT analyses) and reading accuracy pre-follow-up (CC and ITT analyses). This first, to our knowledge, study to examine the efficacy of adaptive WM training for children with TBI provides preliminary evidence of near and far transfer of training to WM and academic skills, respectively.

Early Enteral Combined with Parenteral Nutrition Treatment for Severe Traumatic Brain Injury: Effects on Immune Function, Nutritional Status and Outcomes.
Objective To compare the conjoint effect of enteral nutrition (EN) and parenteral nutrition (PN) with single EN or PN on immune function, nutritional status, complications and clinical outcomes of patients with severe traumatic brain injury (STBI). Methods A prospective randomized control trial was carried out from January 2009 to May 2012 in Neurological Intensive Care Unit (NICU). Patients of STBI who met the enrolment criteria (Glasgow Coma Scale score 6~8; Nutritional Risk Screening ≥3) were randomly divided into 3 groups and were admi- nistrated EN, PN or EN+PN treatments respectively. ⋯ Compared to the EN group, the complication occurrence rates of EN+PN group were significantly lower in aspirated pneumonia (27.5% vs. 50.0%; χ2= 6.39, P<0.05), hypoproteinemia (17.5% vs. 55.0%; χ2= 18.26, P<0.01) and diarrhea (20.0% vs. 60.0%; χ2= 20.00, P<0.01). The EN+PN group also had significant less length of stay in NICU (t=2.51, 4.82; P<0.05, P<0.01), number of patients receiving assisted mechanical ventilation (χ2= 6.08, 12.88; P<0.05, P<0.01) and its durations (t=3.41, 9.08; P<0.05, P<0.01), and the death rate (χ2=7.50, 16.37; P<0.05, P<0.01) than those of EN or PN group. Conclusion Early EN+PN treatment could promote the recovery of the immune function, enhance nutritional status, decrease complications and improve the clinical outcomes in patients with severe traumatic brain injury.

Randomized Controlled TrialProgressive hemorrhagic injury after severe traumatic brain injury: effect of hemoglobin transfusion thresholds.
OBJECT There is limited literature available to guide transfusion practices for patients with severe traumatic brain injury (TBI). Recent studies have shown that maintaining a higher hemoglobin threshold after severe TBI offers no clinical benefit. The present study aimed to determine if a higher transfusion threshold was independently associated with an increased risk of progressive hemorrhagic injury (PHI), thereby contributing to higher rates of morbidity and mortality. ⋯ PHI was associated with a longer median length of stay in the intensive care unit (18.3 vs 14.4 days, respectively; p = 0.04) and poorer Glasgow Outcome Scale scores (42.9% vs 25.5%, respectively; p = 0.02) at 6 months. CONCLUSIONS A higher transfusion threshold of 10 g/dl after severe TBI increased the risk of severe PHI events. These results indicate the potential adverse effect of using a higher hemoglobin transfusion threshold after severe TBI.

Randomized Controlled TrialMyocardial function at the early phase of traumatic brain injury: a prospective controlled study.
The concept of brain-heart interaction has been described in several brain injuries. Traumatic brain injury (TBI) may also lead to cardiac dysfunction but evidences are mainly based upon experimental and clinical retrospective studies. ⋯ STE revealed a correct adaptation of the left systolic function, while the diastolic function slightly impaired.
