Objective: The goal of this study was to examine the associations among posttraumatic stress disorder (PTSD), traumatic brain injury (TBI), sleep quality, pain interference, and quality of life in combat veterans.
Method: Veterans ( = 289, 86.51% male) completed the Mid-Atlantic MIRECC Assessment of Traumatic Brain Injury, the Clinician-Administered PTSD Scale for , and measures of sleep quality, pain interference, and quality of life.
Results: Hierarchical linear regressions evaluated associations between PTSD severity, deployment TBI severity, sleep quality, and the outcomes of pain interference and quality of life after adjusting for demographic variables and the number of nondeployment TBIs. PTSD severity, = 0.15, 0.04, deployment TBI severity, = 3.98, = 1.01, and sleep quality, = 0.74, = 0.13, were significantly associated with pain interference, < .001. PTSD severity, = -0.57, = 0.07, and pain interference, = -0.45 = 0.11, were significantly, independently associated with quality of life < .001. However, pain interference, B = -0.24, SE B = 0.11, was no longer significantly associated with quality of life when sleep quality, = -1.56, = 0.25, was included in the model. There was no significant association between deployment TBI severity and quality of life. Interactions among the studied variables were not significant for either of the outcome variables.
Conclusions: PTSD symptom severity, deployment TBI history, and sleep quality may be important to consider in treatment planning for veterans experiencing pain-related functional interference. For veterans with numerous conditions comorbid with pain, treatment plans may include interventions targeting sleep and PTSD to maximize quality of life improvements.

Purpose: Pain is inherently salient and so draws our attention in addition to impacting performance on attention-demanding tasks. Individual variability in pain-attention interactions can be assessed by two kinds of behavioral phenotypes that quantify how individuals prioritize pain versus attentional needs. The intrinsic attention to pain (IAP) measure quantifies the degree to which a person attends to pain (high-IAP) or mind-wanders away from pain (low-IAP).

Introduction: This study aimed to determine the relative efficacy of mindfulness-based stress reduction (MBSR) or cognitive behaviour therapy (CBT) in comparison to a waitlist control (WLC) for people with rheumatoid arthritis (RA). Participants completed assessments before and after treatment and at 6-month follow-up.
Methods: Two hundred and sixty-nine participants with RA were recruited and randomised in a 2:2:1 ratio to MBSR:CBT:WLC.

There is an ongoing need to identify novel pharmacological agents for the effective treatment of depression. One emerging candidate, which has demonstrated rapid-acting antidepressant effects in treatment-resistant groups, is nitrous oxide (NO)-a gas commonly used for sedation and pain management in clinical settings and with a range of pharmacological effects, including antagonism of NMDA glutamate receptors. A growing body of evidence suggests that subanaesthetic doses of NO (50%) can interfere with the reconsolidation of maladaptive memories in healthy participants and across a range of disorders.
