Our objective was to investigate the effectiveness of booster sessions after self-management interventions as a means of maintaining self-management behaviours in the treatment of chronic musculoskeletal pain. We searched MEDLINE, EMBASE, Science Citation Index, Cochrane Central Register of Controlled Trials, and PsychINFO. Two authors independently identified eligible trials and collected data. ⋯ There is currently little evidence that booster sessions are an effective way to prolong positive treatment effects or improve symptoms of long-term musculoskeletal conditions after self-management interventions. However, the studies were few with high heterogeneity, high risk of bias, and overall low quality of evidence. Our review argues against including booster sessions routinely to self-management interventions for the purpose of behaviour maintenance.

Millions of patients with cancer pain are treated with prescription opioids each year. However, efforts to mitigate the ongoing opioid crisis result in unintended consequences with opioid pain management, including opioid stigma. Emerging research indicates that opioid stigma is problematic in patients with cancer, but few studies have examined contributors to and impacts of opioid stigma in this population. ⋯ Development of the OSF was guided by a literature review of stigma in health-related conditions, adaptation of the existing Health Stigma and Discrimination Framework, a topical review of challenges related to opioid cancer pain management, and author expertise in cancer, pain, and opioid prescribing. The proposed OSF highlights 5 domains: (1) contributors to opioid stigma, or factors that increase the likelihood that a patient will experience opioid stigma; (2) intersecting stigmas, or the convergence of multiple stigmatized identities within a patient; (3) stigma manifestations, or the ways opioid stigma is manifested in patients, clinicians, and the community; (4) proximal outcomes, or the immediate consequences of opioid stigma in patients; and (5) long-term impacts in patients. The OSF provides 2 main avenues to facilitate future research: (1) providing a framework to explore the mechanisms that underlie opioid stigma and its impact on cancer pain management and (2) supporting the development of targeted, tailored interventions to eliminate opioid stigma.

Chronic pain in childhood is an international public health problem. We conducted a systematic review and meta-analysis to provide a summary of the published evidence of pharmacological, physical, and psychological therapies for children with chronic pain conditions. We searched CENTRAL, MEDLINE, EMBASE, and PsycINFO from inception to April 2020; clinical trial registries; and other sources for randomised controlled trials or comparative observational trials. ⋯ The largest evidence base for the management of chronic pain in children supports the use of psychological therapies, followed by pharmacological and physical therapies. However, we rated most outcomes as low or very low certainty, meaning further evidence is likely to change our confidence in the estimates of effects. This protocol was registered on PROSPERO (CRD42020172451).

Meta Analysis
Risk factors for persistent pain after breast and thoracic surgeries: a systematic literature review and meta-analysis.
Persistent postsurgical pain (PPSP) is common after breast and thoracic surgeries. Understanding which risk factors consistently contribute to PPSP will allow clinicians to apply preventive strategies, as they emerge, to high-risk patients. The objective of this work was to systematically review and meta-analyze the literature on risk factors of PPSP after breast and thoracic surgeries. ⋯ In thoracic surgery, younger age, female sex, hypertension, preoperative pain, moderate to severe acute postoperative pain, surgical approach, major procedure, and wound complications were associated with PPSP. This systematic review demonstrated certain consistent risk factors of PPSP after breast and thoracic surgeries, as well as identified research gaps. Understanding the factors that increase susceptibility to PPSP can help selectively allocate resources to optimize perioperative care in high-risk patients and help develop targeted, risk-stratified interventions for PPSP prevention.

Exercise and pain neuroscience education (PNE) have both been used as standalone treatments for chronic musculoskeletal pain. The evidence supporting PNE as an adjunct to exercise therapy is growing but remains unclear. The aim of this systematic review and meta-analysis was to evaluate the effect of combining PNE and exercise for patients with chronic musculoskeletal pain, when compared with exercise alone. ⋯ Long-term outcomes (>12 weeks) were only available for 2 studies and therefore were not suitable for meta-analysis. Meta-analysis revealed a significant difference in pain (weighted mean differences, -2.09/10; 95% confidence interval [CI], -3.38 to -0.80; low certainty), disability (standardized mean difference, -0.68; 95% CI, -1.17 to -0.20; low certainty), kinesiophobia (standardized mean difference, -1.20; CI, -1.84 to -0.57; moderate certainty), and pain catastrophizing (weighted mean differences, -7.72; 95% CI, -12.26 to -3.18; very low certainty) that favoured the combination of PNE and exercise. These findings suggest that combining PNE and exercise in the management of chronic musculoskeletal pain results in greater short-term improvements in pain, disability, kinesiophobia, and pain catastrophizing relative to exercise alone.
