Little is known about the consequences of the opioid epidemic on people living with chronic noncancer pain (CNCP). This study examined this issue in people who lived in the most impacted province by opioid overdoses in Canada (British Columbia [BC]) or one of the least impacted (Quebec [QC]), and examined the factors associated with opioid use. ⋯ The opioid epidemic and associated prescribing restrictions have had harmful effects on Canadians with CNCP. The clinical community, the general public, and the media need to be aware of these negative consequences to decrease patients' stigmatization and minimize inadequate treatment of CNCP.

Acute pain is the main complication of sickle cell disease. Chronic pain (CP) and neuropathic pain (NP) may also be experienced, but have not been formally described in Jamaican patients. A cross-sectional study was conducted to determine their prevalence and characteristics, and to determine the common pain locations and modalities of management. ⋯ CP and NP should be assessed during routine care of sickle cell pain so that targeted therapies can be applied.

Perceived injustice (PI), which is one's appraisal of justice or fairness regarding the pain experience, is an emerging area of interest in pediatric pain research. No previous studies have investigated PI in youth with acute pain. To fill this gap, this study examined (1) associations among PI, pain-related function, and psychological function in treatment-seeking youth with acute musculoskeletal (MSK) pain, and (2) the impact of parent-child PI discordance on children's pain and psychosocial function. ⋯ These findings reveal that PI in youth with acute MSK pain is associated with quality of life and pain-related disability. Furthermore, results highlight the importance of discordance between youth and parent reports of PI on pain-related functioning.

Reassurance is an important part of treatment for low back pain (LBP). The Consultation-based Reassurance Questionnaire measures patients' perceived reassurance after health care consultations on 4 subdomains (ie, Data-gathering, Relationship-building, Generic reassurance, Cognitive reassurance). The objectives of this study were to investigate associations between the level of reassurance and outcomes and to investigate if the associations were moderated by patients' risk profile. ⋯ Identified associations between reassurance and outcomes were weak, however, for GPE the association might be of a clinically relevant magnitude. The causal relationship is unclear, but with communication always present in a consultation these results suggest that efforts to optimize clinician-patient communication might be worthwhile, also for people with very recent onset of LBP.

Investigation if emotional reactivity by measuring heart rate variability (HRV) and pressure pain sensitivity during a passive visualization task in participants with chronic low back pain (CLBP). ⋯ Aversive environmental stimuli, such as visual cues, may generate defensive physiological reactions. HRV can provide a measure that reflects the perceptions of threat and safety in the environment. Participants with CLBP presented changes in sympathovagal balance during passive visualization of pictures of daily activities, higher pain sensitivity, and high pain intensity when they were exposed to a passive visualization task using pictures of daily living that may arouse fears of harm.
