Executive Functions and Theory of Mind as Predictors of Social Adjustment in Childhood Traumatic Brain Injury.
This study examined whether executive function and theory of mind mediate the effects of pediatric traumatic brain injury (TBI) on social adjustment, relative to children with orthopedic injury (OI). Participants included 19 children with severe TBI, 41 children with complicated mild/moderate TBI, and 57 children with OI. They completed measures of executive function, as well as cognitive, affective, and conative theory of mind. ⋯ Theory of mind was a significant independent mediator when predicting social skills, but executive function was not. TBI in children, particularly severe injury, is associated with poor social adjustment. The impact of TBI on children's social adjustment is likely mediated by its effects on executive function and theory of mind.

Nociceptive sensitization and BDNF up-regulation in a rat model of traumatic brain injury.
Chronic pain after traumatic brain injury (TBI) is very common, but the mechanisms linking TBI to pain experienced in the periphery have not been described. In this set of studies we examined nociceptive sensitization and changes in spinal cord gene expression using the rat lateral fluid percussion model of mild TBI. ⋯ We also found that spinal cord levels of brain derived neurotrophic factor (BDNF) but not several other pain-related genes were up-regulated one week after injury. Our findings suggest that TBI-induced up-regulation of spinal BDNF levels might contribute to chronic TBI-related pain, and that the lateral fluid percussion model might be useful for exploring this relationship.

Comparative Study
Long-term comparison of GOS-E scores in patients treated with phenytoin or levetiracetam for posttraumatic seizure prophylaxis after traumatic brain injury.
Much debate exists on the optimal medication for posttraumatic seizure prophylaxis after traumatic brain injury (TBI). There is some evidence that levetiracetam (LEV) could be neuroprotective and provide long-term benefits in this patient population. ⋯ Long-term functional outcome in patients who experienced a TBI was not affected by treatment with PHT or LEV; however, patients treated with PHT had a higher incidence of fever during hospitalization.

To study blast-induced traumatic brain injury (bTBI) characteristics in confined space. ⋯ Blast-induced traumatic brain injury can be induced by a complex blast wave with a pressure and duration of 45/71 kPa and 2.7/2.367 milliseconds. Its severity is related to the features and waveforms of the blast.

Premature mortality is a public health concern that can be quantified as years of potential life lost (YPLL). Studying premature mortality can help guide hospital initiatives and resource allocation. We investigated the categories of neurologic and neurosurgical conditions associated with in-hospital deaths that account for the highest YPLL and their trends over time. ⋯ The in-hospital mortality rate has been stable or decreasing for all of these diagnoses except TBI, which rose from 5.1% in 1988 to 7.8% in 2011. Using YPLL, we provide a framework to compare the burden of premature in-hospital mortality on patients with neurologic disorders, which may prove useful for informing decisions related to allocation of health resources or research funding. Considering premature mortality alone, increased efforts should be focused on TBI, particularly in and related to the hospital setting.
