Exploring the kynurenine pathway in mild traumatic brain injury: A longitudinal study.

A potential source of novel biomarkers for mTBI is the kynurenine pathway (KP), a metabolic pathway of tryptophan (Trp), that is up-regulated by neuroinflammation and stress. Considering that metabolites of the KP (kynurenines) are implicated in various neuropsychiatric diseases, exploration of this pathway could potentially bridge the gap between physiological and psychological factors in the recovery process after mTBI. This study, therefore, set out to characterize the KP after mTBI and to examine associations with long-term outcome.

Good Health-Related Quality of Life in Older Patients One Year after mTBI despite Incomplete Recovery: An Indication of the Disability Paradox?

Objectives: To determine the prevalence and potential risk factors of acute and chronic post-traumatic headache (PTH) in patients with mild to moderate traumatic brain injury (TBI) in a prospective longitudinal observational multicentre study. Acute PTH (aPTH) is defined by new or worsening of pre-existing headache occurring within 7 days after trauma, whereas chronic PTH (cPTH) is defined as persisting aPTH >3 months after trauma. An additional goal was to study the impact of aPTH and cPTH in terms of return to work (RTW), anxiety and depression.

Early predictors of outcome after mild traumatic brain injury (UPFRONT): an observational cohort study.

Background: Mild traumatic brain injury (mTBI) accounts for most cases of TBI, and many patients show incomplete long-term functional recovery. We aimed to create a prognostic model for functional outcome by combining demographics, injury severity, and psychological factors to identify patients at risk for incomplete recovery at 6 months. In particular, we investigated additional indicators of emotional distress and coping style at 2 weeks above early predictors measured at the emergency department.

Stability of coping and the role of self-efficacy in the first year following mild traumatic brain injury.

Background And Aims: Coping, the psychological adaptation to stressors and serious life events, has been found to have a great influence on the development and persistence of posttraumatic complaints. Coping has received much attention for having been found to be modifiable in treatment following mild traumatic brain injury (mTBI) and for its potential to identify the Patients who are at risk of suffering from long-term complaints. Currently, coping styles are assumed to be stable over time.

Cognitive Behavioral Intervention Compared to Telephone Counseling Early after Mild Traumatic Brain Injury: A Randomized Trial.

Many patients do not return to work (RTW) after mild traumatic brain injury (mTBI) because of persistent complaints that are often resistant to therapy in the chronic phase. Recent studies suggest that psychological interventions should be implemented early post-injury to prevent patients from developing chronic complaints. This study is a randomized, controlled trial that examines the effectiveness of a newly developed cognitive behavioral therapy (CBT) intervention (CBTi) compared to telephonic counseling (TC) in at-risk mTBI patients (patients with high reports of early complaints).
