Intracranial neurosurgical disorders are important causes of mortality and disability worldwide. Low tri-iodothyronine (T3) syndrome is a common complication in critically ill patients and is associated with a poor prognosis. ⋯ Low T3 syndrome is a common complication in patients suffering from intracranial neurosurgical disorders and is associated with greater disease severity, complicated clinical course, and greater mortality and handicap rates. However, it remains unclear if low T3 syndrome can impact the findings of currently available clinical prognostic models and if management of low T3 syndrome can improve outcomes in neurosurgical patients.

Brain tissue oxygen tension and its response to physiological manipulations: influence of distance from injury site in a swine model of traumatic brain injury.
OBJECTIVE The optimal site for placement of tissue oxygen probes following traumatic brain injury (TBI) remains unresolved. The authors used a previously described swine model of focal TBI and studied brain tissue oxygen tension (PbtO2) at the sites of contusion, proximal and distal to contusion, and in the contralateral hemisphere to determine the effect of probe location on PbtO2 and to assess the effects of physiological interventions on PbtO2 at these different sites. METHODS A controlled cortical impact device was used to generate a focal lesion in the right frontal lobe in 12 anesthetized swine. ⋯ Physiological alterations, including hyperoxia, hyperventilation, and hypoventilation substantially affect PbtO2 values distal to the site of injury but have little effect in and around the site of contusion. Clinical interpretations of brain tissue oxygen measurements should take into account the spatial relation of probe position to the site of injury. The decision of where to place a brain tissue oxygen probe in TBI patients should also take these factors into consideration.

Predictors of the On-Road Driving Assessment After Traumatic Brain Injury: Comparing Cognitive Tests, Injury Factors, and Demographics.
(1) To examine the relations between performance on cognitive tests and on-road driving assessment in a sample of persons with traumatic brain injury (TBI). (2) To compare cognitive predictors of the on-road assessment with demographic and injury-related predictors. ⋯ Cognitive tests are not reliable predictors of the on-road driving assessment outcome. Traumatic brain injury severity may be a better predictor of on-road driving; however, further research is needed to identify the best predictors of driving behavior after TBI.

Recovery of episodic memory subprocesses in mild and complicated mild traumatic brain injury at 1 and 12 months post injury.
Episodic memory complaints are commonly reported after traumatic brain injury (TBI). The contributions of specific memory subprocesses (encoding, consolidation, and retrieval), however, are not well understood in mild TBI (mTBI). In the present study, we evaluated subprocesses of episodic memory in patients with mTBI using the item-specific deficit approach (ISDA), which analyzes responses on list learning tasks at an item level. We also conducted exploratory analyses to evaluate the effects of complicated mTBI (comp-mTBI) on memory. ⋯ These findings indicate that, while the NC-mTBI and HC groups' performances were comparable by 12 months, a primary, long-term deficit in encoding of auditory verbal information remained problematic in the comp-mTBI group.

Injuries Associated With Strollers and Carriers Among Children in the United States, 1990 to 2010.
To describe the incidence, rate, and characteristics of injuries associated with strollers and carriers among young children in the United States. ⋯ Stroller- and carrier-related injuries, specifically those resulting from falls from the product or tip-overs, are important sources of injury for children 5 years of age and younger. Although injuries over the 21-year study period decreased overall, the considerable number of injuries annually shows the need to further reduce the potential for injury associated with these ubiquitous products.
