Comparative StudyAssessment of Health-Related Quality of Life after TBI: Comparison of a Disease-Specific (QOLIBRI) with a Generic (SF-36) Instrument.
Psychosocial, emotional, and physical problems can emerge after traumatic brain injury (TBI), potentially impacting health-related quality of life (HRQoL). Until now, however, neither the discriminatory power of disease-specific (QOLIBRI) and generic (SF-36) HRQoL nor their correlates have been compared in detail. These aspects as well as some psychometric item characteristics were studied in a sample of 795 TBI survivors. ⋯ Notably, the SF-36 "Role Physical," "Role Emotional," and "Social Functioning" subscales showed less satisfactory discriminatory power than all other dimensions or the sum scores of both instruments. The absolute informativity of disease-specific as well as generic HRQoL instruments concerning the different groups defined by different correlates differed significantly. When the focus is on how a certain subscale or sum score differentiates between individuals in one specific dimension/health state, the QOLIBRI can be recommended as the preferable instrument.

Chronic pain conditions are highly prevalent in patients with mild traumatic brain injury. Supraspinal diffuse axonal injury is known to dissociate brain functional connectivity in these patients. The effect of this dissociated state on supraspinal pain network is largely unknown. A functional magnetic resonance imaging study was conducted to compare the supraspinal pain network in patients with mild traumatic brain injury to the gender and age-matched healthy controls with the hypothesis that the functional connectivities of the medial prefrontal cortices, a supraspinal pain modulatory region to other pain-related sensory discriminatory and affective regions in the mild traumatic brain injury subjects are significantly reduced in comparison to healthy controls. ⋯ In short, the current study demonstrates that patients with mild traumatic brain injury and headaches appear to have an altered state of supraspinal modulatory and affective functions related to pain perception.

Case ReportsDegeneration of an injured spinothalamic tract in a patient with mild traumatic brain injury.
This study reports on a patient who developed degeneration of an injured spinothalamic tract (STT) detected on diffusion tensor tractography (DTT) following mild traumatic brain injury (TBI). ⋯ This study recommends further studies conducted on the prognosis (regeneration or degeneration) of injured STTs and on the effect of change of an injured STT on central pain.

This study aimed to compare pressure regulated volume control (PRVC) and synchronized intermittent mechanical ventilation (SIMV) modes of ventilation according to respiratory and hemodynamic stability in patients with traumatic brain injury (TBI) admitted to Intensive Care Unit (ICU). ⋯ Using PRVC mode might be more desirable than using SIMV mode in patients with TBI due to better stability of ventilation and oxygenating. To ensure for more advantages of PRVC mode, further studies with longer follow-up and more detailed measurements are recommended.

Early CT frontal abnormalities predict long term neurobehavioral problems but not affective problems after moderate to severe TBI.
Behavioral problems are serious consequences of moderate to severe traumatic brain injury (TBI) and have a negative impact on outcome. There may be two types: neurobehavioral problems, manifesting as inadequate social behavior resulting from prefrontal system damage, and affective behavioral problems, resulting from emotional distress as a reaction to the brain injury. In the present study we investigated whether these two types of behavioral problems, as indicated by proxies, could be distinguished in a group of chronic TBI patients and whether early indicators of prefrontal damage on imaging could predict long-term neurobehavioral problems. ⋯ Long-term neurobehavioral problems were significantly correlated to one-year outcome and return to work in the long term. We conclude that in patients with moderate to severe TBI neurobehavioral and affective problems can be distinguished. Early CT frontal abnormalities predict long-term neurobehavioral problems, but not affective problems.
