Randomized Controlled Trial
Evaluation of the Efficacy of Prolonged Pregabalin Administration before and after Surgery in Patients Undergoing Arthroscopic Anterior Cruciate Ligament Repair: A Prospective, Randomized, Double-Blind Study.
Reconstruction of the knee ligament causes postoperative pain and delayed rehabilitation. ⋯ A prolonged preoperative and postoperative pregabalin prescription for anterior cruciate ligament repair decreased the need for supplementary analgesics during the first 24 postoperative hours but increased dizziness.

Observational Study
Psychological Predictors of Perceived Age and Chronic Pain Impact in Individuals with and without Knee Osteoarthritis.
Chronological age is a risk factor in chronic pain; however, aging research supports the premise that physical and psychological health may better predict perceived age. Given the lack of evidence on perceived age in the context of chronic pain, the current study presents novel findings about the relationship between perceived age, chronic pain impact, and psychological function in adults with and without knee osteoarthritis. ⋯ These findings highlight the importance of a biopsychosocial approach in understanding the intersection between psychological and physical factors associated with chronic pain. Addressing negative self-perceptions of aging, while simultaneously augmenting positive affect, through psychological therapies may mitigate pain and disability.

The opioid epidemic is a significant public health problem that is associated with overdose and death. The increase in opioid-related problems can largely be attributed to increases in opioid prescriptions for the treatment of chronic pain. Unfortunately, there is not a consensus on a definition of opioid misuse in the context of chronic pain, making measurement a challenge. One commonly used measure to assess opioid misuse in the context of chronic pain is the Current Opioid Misuse Measure (COMM). The COMM was designed to assess opioid misuse generally, as captured by psychiatric symptoms and aberrant drug use behaviors. Although studies have examined cross-validation using correlations, little psychometric work has been conducted, and therefore it is currently unknown what domains the measure is assessing. ⋯ Given the importance and relevance for opioid misuse in the context of chronic pain, it is important for researchers to continue assessing and providing psychometric evidence for the COMM.

The objective of this study was to summarize the current status of knowledge about the longitudinal association between vulnerability or protective psychological factors and the onset and/or persistence of musculoskeletal (MSK) pain. ⋯ The large number of methodological flaws found across reviews gives rise to a call to action to develop high-quality systematic reviews in this field.

Recent years have seen an increase in the adoption of cannabinoid medicines, which have demonstrated effectiveness for the treatment of chronic pain. However, the extent to which frequent cannabis use (CU) influences sensitivity to acute pain has not been systematically examined. Such a determination is clinically relevant in light of hypersensitivity to pain associated with prolonged use of other analgesics such as opioids, and reports of increased pain sensitivity to experimentally induced pain during acute cannabis intoxication. This study explored differences in measures of pain intensity and tolerance. The authors hypothesized that individuals who report frequent CU would demonstrate greater experimental pain sensitivity. ⋯ Frequent cannabis users did not demonstrate hyperalgesia. This finding should help to inform evaluations of the relative harms and benefits of cannabis analgesic therapies.
