Randomized Controlled Trial
The Effect of Scheduled Intravenous Acetaminophen in an Enhanced Recovery Protocol Pathway in Patients Undergoing Major Abdominal Procedures: A Prospective, Randomized, and Placebo-Controlled Clinical Trial.
Enhanced recovery protocols (ERPs) utilize multi-modal analgesia regimens. Individual regimen components should be evaluated for their analgesic efficacy. We evaluated the effect of scheduled intravenous (IV) acetaminophen within an ERP on analgesia and recovery after a major abdominal surgery. ⋯ Scheduled administration of IV acetaminophen did not improve postoperative analgesia or characteristics of postoperative recovery in patients undergoing major abdominal surgery within an ERP pathway.

Randomized Controlled Trial
Efficacy of anodal suboccipital direct current stimulation for endogenous pain modulation and tonic thermal pain control in healthy participants: a randomised controlled clinical trial.
The aim of this study was to assess whether anodal DCS applied to the suboccipital (SO) target area could potentiate antinociception assessed primarily with conditioned pain modulation of tonic thermal test stimuli. ⋯ Although heterotopic CPM was not facilitated with either SO-DCS or M1-DCS, a general significant inhibition of tonic cold pain intensity was demonstrated following both interventions. The general effects of active DCS compared to sham on tonic cold pain-irrespective of the M1 or SO target-need to be confirmed using standard quantitative sensory testing.

Randomized Controlled Trial
Opioid use as a predictor of pain outcomes in Iraq and Afghanistan Veterans with chronic pain: Analysis of a randomized controlled trial.
Our objectives were to: 1) assess the relationship between self-reported opioid use and baseline demographics, clinical characteristics and pain outcomes; and 2) examine whether baseline opioid use moderated the intervention effect on outcomes at 9 months. ⋯ In a stepped-care trial for pain, patients reporting baseline opioid use had greater improvement in pain disability at 9 months compared to patients not reporting opioid use.

Randomized Controlled Trial
Effect of pregabalin on the EC50 of intravenous alfentanil in capsaicin induced pain.
To apply the sequential up-down method to a human experimental pain model in order to examine the opioid-sparing effect of oral pregabalin on intravenous alfentanil. ⋯ When the intradermal capsaicin-induced pain model was used in healthy volunteers, oral pregabalin had no opioid-sparing effects on intravenous alfentanil. This experimental model may be useful in studying analgesic interactions.

Randomized Controlled Trial
Associations of Coexisting Pain and Fatigue Severity with Physical Performance and Quality of Life among Middle-Aged and Older Individuals with Chronic Knee Pain: A randomized controlled trial.
To examine associations of combined pain and fatigue severity with physical performance and quality of life in people with chronic knee pain. ⋯ Coexisting moderate pain and moderate fatigue were related to worse physical performance and QOL. Fatigue contributed to lower levels of mental QOL. Clinical assessment of fatigue in addition to pain should be included as a standard examination for chronic knee pain.
