Randomized Controlled Trial
Eye-movement behaviours when viewing real-world pain-related images.
Pain-related cues are evolutionarily primed to capture attention, although evidence of attentional biases towards pain-related information is mixed in healthy individuals. The present study explores whether healthy individuals show significantly different eye-movement behaviours when viewing real-world pain-related scenes compared to neutral scenes. The effect of manipulating via written information the threat value of the pain-related scenes on eye-movement behaviours was also assessed. ⋯ Healthy individuals show different eye-movement behaviours when viewing pain-related scenes than neutral scenes, supporting evolutionary accounts of pain. Implications for the onset and/or maintenance of chronic pain need to be explored.

Randomized Controlled Trial
The effect of total intravenous anaesthesia with propofol on postoperative pain after third molar surgery: a double blind randomized controlled trial.
Total intravenous anaesthesia (TIVA) with propofol may reduce pain after surgery compared with inhalational anaesthetic techniques. Whether propofol provides analgesic benefit may be influenced by the surgical procedure and anaesthetic/analgesic regime. Third molar surgery is a consistent and fairly standard surgical technique that provides a good model for postoperative pain. We investigated whether propofol TIVA or sevoflurane (SEVO) inhalational anaesthesia would produce better quality pain relief after third molar surgery. ⋯ Choice of general anaesthetic technique can affect postoperative analgesia. The results of this study suggest that propofol TIVA improves postoperative pain and patient satisfaction after third molar surgery compared to inhalational anaesthesia.

Randomized Controlled Trial Comparative Study
The relative efficacy of mindfulness versus distraction: The moderating role of attentional bias.
This study investigated whether the ability to disengage quickly from pain-related stimuli moderated the relative efficacy of a mindfulness-based intervention versus distraction in response to an experimental pain task. ⋯ This study demonstrated the efficacy of a novel, exposure-based mindfulness technique for pain tolerance and showed that those who disengaged easily from pain stimuli benefited most. This brief task could be clinically useful, particularly for those who are not overly focused on their pain symptoms.

Randomized Controlled Trial
Exposure and cognitive-behavioral therapy for chronic back pain: an RCT on treatment processes.
To improve treatment outcomes, it is essential to understand the processes involved in therapeutic change. The aim of this study was to investigate the processes involved in treatment of individuals with chronic lower back pain (CLBP) and high fear-avoidance. Graded in vivo exposure (Exposure), a specific treatment, and cognitive-behavioural therapy (CBT), a general treatment, were compared. ⋯ We identified several treatment processes (e.g., reduction of fear of movement, enhancement of self-efficacy), which were associated with disability reduction during the management of chronic pain and fear-avoidance. These processes appeared to be equally important for Exposure and CBT. Practitioners should optimize these processes to improve their patients' functioning.

Randomized Controlled Trial
Intraoperative S-ketamine for the reduction of opioid consumption and pain one year after spine surgery: A randomized clinical trial of opioid dependent patients.
We aimed to explore the effect of intraoperative S-ketamine on analgesic consumption and pain one year after spine surgery in chronic opioid-dependent patients undergoing spinal fusion surgery. ⋯ This randomized clinical trial shows that intraoperative ketamine may reduce opioid use and pain and improve labour market attachment one year after spine surgery in an opioid-dependent population.
