Review Meta Analysis
Relative contributions of the nervous system, spinal tissue and psychosocial health to non-specific low back pain: Multivariate meta-analysis.
Nervous system, psychosocial and spinal tissue biomarkers are associated with non-specific low back pain (nsLBP), though relative contributions are unclear. ⋯ Spinal structural lesions (e.g. intervertebral disc degeneration), psychosocial (e.g. depression) and nervous system factors (detected by e.g. quantitative sensory tests, structural and functional measures) contribute to non-specific low back pain. However, psychosocial factors may be more compromised than nervous system and spinal imaging biomarkers. This relationship depends on if the pain is acute or chronic. These findings underscore that the 'non-specific' label in back pain should be reconsidered, and more specific multidimensional categories evaluated to guide patient management.

This study was designed to evaluate the efficacy of analgesia and incidence of postoperative nausea and vomiting (PONV) of several widely used clinical treatments for postoperative analgesia following abdominal surgery through network meta-analysis (NMA) based on published randomized controlled trials (RCTs). ⋯ The findings from our work provide evidence that preoperative paravertebral block was superior to continuous or postoperative wound infiltration to provide postoperative analgesia, nausea and vomiting after abdominal surgery.

This investigation comprised information from the Danish population to analyse the development of chronic non-cancer pain (CNCP) prevalence according to sex, age, physical job demand and educational level. ⋯ This study provides an overview of the development of chronic non-cancer pain in a country and analyses the trends with socioeconomic inequalities. The continuous increasing prevalence may have huge social and economic implications. This study reveals an urgent need for measures to attenuate the increasing prevalence, which should be a priority for public health policy.
