Pilot of a novel intervention for postconcussive symptoms in active duty, veterans, and civilians.

Purpose/objective: The authors present a study aimed at pilot testing a novel delivery method, namely a computer intervention, for postconcussive symptom reduction in active duty, veteran, and civilian patients with acute and chronic complaints. Following a concussion/mild traumatic brain injury (MTBI), most individuals recover completely, but a significant proportion report postconcussive symptoms months to years following the injury. Psychoeducational intervention has shown to be effective in reducing postconcussive symptoms in studies done with acute civilian samples, but the efficacy of psychoeducational interventions with individuals who served in combat or have chronic complaints remains unclear.

Impaired executive function is associated with delirium after coronary artery bypass graft surgery.

Objectives: To determine the extent to which preoperative performance on tests of executive function and memory was associated with delirium after coronary artery bypass graft (CABG) surgery.

Design: Prospective observational cohort study.

Setting: Two academic medical centers and one Department of Veterans Affairs medical center in Massachusetts.
