Impact of reduced k-space acquisition on pathologic detectability for volumetric MR spectroscopic imaging.
To assess the impact of accelerated acquisitions on the spectral quality of volumetric magnetic resonance spectroscopic imaging (MRSI) and to evaluate their ability in detecting metabolic changes with mild injury. ⋯ Although the reduced encoding method is associated with lower signal-to-noise ratio (SNR) that impacts the quality of spectral analysis, the use of the parallel imaging method can lead to the same diagnostic outcomes as the fully sampled data when using the sensitivity-limited volumetric MRSI.

Astragaloside (AST) is traditionally prescribed for the prevention and treatment of cerebrovascular diseases. We directly tested the therapeutic effects of AST in a rat model of traumatic brain injury (TBI). ⋯ TBI-induced microglial activation evidenced by the morphological transformation of microglia (or ameboid microglia) and the microglial overexpression of tumor necrosis factor-alpha was reduced by AST. Our results indicate that AST may protect against brain contusion and neuronal apoptosis after TBI by attenuating microglia activation in male rats.

Randomized Controlled Trial Multicenter Study Comparative StudyMood disorders after traumatic brain injury in adolescents and young adults: a nationwide population-based cohort study.
To delineate the relationship between traumatic brain injury (TBI) and mood disorders from population-based data in Taiwan. ⋯ Our findings show a higher likelihood of manifesting mood disorders in adolescents and young adults who sustained a prior TBI. Health professionals should carefully monitor both the physical and psychological impacts of head trauma.

ReviewGlucose and the injured brain-monitored in the neurointensive care unit.
Brain has a continuous demand for energy that is met by oxidative metabolism of oxygen and glucose. This demand is compromised in the injured brain and if the inadequate supply persists it will lead to permanent tissue damage. Zero values of cerebral glucose have been associated with infarction and poor neurological outcome. ⋯ Available data suggest that low cerebral glucose in patients with TBI and SAH provides valuable information on development of secondary ischemia and has been correlated with worse outcome. There is also indication that the location of the catheter is important for correlation between plasma and brain glucose. In conclusion considering catheter location, monitoring of brain glucose in the neurointensive care not only provides information on imminent secondary ischemia it also reveals the effect of peripheral treatment on the injured brain.

Elevated serum ubiquitin C-terminal hydrolase-L1 levels in patients with carbon monoxide poisoning.
Ubiquitin C-terminal hydrolase-L1 (UCH-L1) has been established as a reliable and potential biomarker of neuronal damage after acute neurologic insults, such as ischemic stroke, subarachnoid hemorrhage, and traumatic brain injury. However, the effect of serum UCH-L1 levels has not been investigated in carbon monoxide (CO)-poisoned patients. The aim of the present study was to evaluate whether serum UCH-L1 levels are a reliable marker of brain damage and the association of UCH-L1 with outcome. ⋯ Serum levels of UCH-L1 appear to have potential clinical utility in providing valuable information about poisoning severity and outcome after CO poisoning.
