Comparative Study
Efficacy and Safety Outcomes in Systematic Reviews of Interventions for Postoperative Pain in Children: Comparison Against the Recommended Core Outcome Set.
To investigate the range of efficacy and safety outcomes used in systematic reviews (SRs) of randomized controlled trials (RCTs) of interventions for postoperative pain in children and compare them with outcome domains recommended in the Pediatric Initiative on Methods, Measurement, and Pain Assessment in Clinical Trials (PedIMMPACT). ⋯ Systematic reviews in the field of pediatric pain do not use the recommended COS. Nor do they consistently include pain as an outcome. This makes comparisons of efficacy and safety across interventions very difficult. Future studies should explore whether the authors are aware of the COS and whether the recommended COS is appropriate.

Mindfulness is a nonpharmacologic mind-body therapy that has been shown to be effective in older adults with chronic low back pain (cLBP). There are few first-person accounts in the literature that describe the older adult experience and perspective while learning mindfulness and meditation to treat pain. The objective of this study was to investigate dominant themes present in the experiences of older adults applying mindfulness and meditation to cope with cLBP. ⋯ The themes identify several ways mindfulness impacts older adults with cLBP, including decreased negative emotions related to chronic pain such as fear of pain, a different perspective or change in awareness about pain, and reducing the significance of pain.

Many studies have provided evidence of altered brain structure in chronic pain conditions, as well as further adaptations following treatment that are coincident with changes in pain. Less is known regarding how these structural brain adaptations relate to assessments of nociceptive processing. The current study aimed to investigate brain structure in people with knee osteoarthritis (OA) before and after total knee arthroplasty (TKA) and to investigate the relationships between these findings and quantitative sensory testing (QST) of the nociceptive system. ⋯ In people with end-stage knee OA, region-specific gray matter atrophy was detected, with further changes in gray matter volume and improvements in white matter integrity observed after joint replacement. Despite coincident alterations in nociceptive inhibition and facilitation processes, there did not appear to be any association between these functional assessments of the nociceptive system and changes in brain structure.
