ReviewUse of regional analgesia to prevent the conversion from acute to chronic pain.
Chronic post-surgical pain (CPSP) prevalence has not changed over the past decades what questions the efficacy of preventive strategies. Regional analgesia is used to control acute pain, but preventive effect on CPSP remains debated. Failures and future application of regional analgesia to prevent transition from acute to chronic pain will be discussed. ⋯ Regional analgesia failure to prevent CPSP development should prompt us to reconsider its perioperative utilization. Patients' stratification, for example high-pain responders, might help to target those who will most benefit of regional analgesia. The impact of regional analgesia on secondary pain-related outcomes such as intensity and neuropathic character despite no difference on CPSP incidence requires more studies. Finally, the preventive effect of regional analgesia targeted interventions on CPSP in patients suffering from severe subacute pain deserves to be assessed.

This study examined the efficacy of internet-delivered cognitive and behavioural interventions for adults with chronic pain AND explored the role of clinical and study characteristics as moderators of treatment effects. PubMed, Embase, PsycINFO, CENTRAL and CINAHL were searched to identify randomized controlled trials published up to October 2021. A meta-analysis of 36 studies (5778 participants) was conducted, which found small effect sizes for interference/disability (Hedges' g = 0.28; 95% confidence interval [CI] 0.21-0.35), depression ( g = 0.43; 95% CI 0.33-0.54), anxiety ( g = 0.32; 95% CI 0.24-0.40), pain intensity ( g = 0.27; 95% CI 0.21-0.33), self-efficacy ( g = 0.39; 95% CI 0.27-0.52) and pain catastrophizing ( g = 0.31; 95% CI 0.22-0.39). ⋯ No differences were found between treatments based on traditional cognitive behaviour therapy vs acceptance and commitment therapy. Sample size, study year, and overall risk of bias (Cochrane rating) did not consistently moderate treatment effects. Overall, the results support the use of internet-delivered cognitive and behavioural interventions as efficacious and suggest guided interventions are associated with greater clinical gains for several key pain management outcomes.

Meta AnalysisA systematic review and meta-analysis of three risk factors for chronic postsurgical pain: age, sex and preoperative pain.
Chronic postsurgical pain (CPSP) is a common and disabling postoperative complication. Several risk factors for CPSP have been established, but it is unclear whether they are significant for any type of surgery. This systematic review aimed to assess the risk of CPSP related to three known preoperative risk factors "age, sex and preoperative pain" in the adult population after any type of elective non-obstetrical surgery. ⋯ This systematic review confirms that younger age, female sex, and preoperative pain are associated with higher risk of developing CPSP in any type of elective non-obstetrical surgery. However, effect sizes are small and quality of evidence low-moderate only, limiting comparisons of different types of surgery.

Review Meta Analysis
A Meta-analysis of the Associations of Elements of the Fear-Avoidance Model of Chronic Pain with Negative Affect, Depression, Anxiety, Pain-related Disability and Pain Intensity.
Biopsychosocial conceptualizations of clinical pain conditions recognize the multi-faceted nature of pain experience and its intersection with mental health. A primary cognitive-behavioural framework is the Fear-Avoidance Model, which posits that pain catastrophizing and fear of pain (including avoidance, cognitions and physiological reactivity) are key antecedents to, and drivers of, pain intensity and disability, in addition to pain-related psychological distress. This study aimed to provide a comprehensive analysis of the magnitude of the cross-sectional association between the primary components of the Fear-Avoidance Model (pain catastrophizing, fear of pain, pain vigilance) with negative affect, anxiety, depression, pain intensity and disabilities in studies of clinical pain. ⋯ This meta-analysis reveals that, among individuals with various pain conditions, pain catastrophizing, fear of pain, and pain vigilance have medium to large associations with pain- related negative affect, anxiety, and depression, pain intensity and disability. Differences in the strength of the associations depend on the type of self-report tool used to assess fear of pain.

Meta Analysis
Cognitive biases among those with frequent or chronic headaches or migraines: a systematic review and meta-analysis.
The aim of this systematic review and meta-analysis was to determine the pattern of cognitive processing biases (ie, attentional, interpretation, and memory bias) towards headache and pain information observed in individuals with frequent or chronic headaches or migraines, compared with individuals without. We identified 11 studies (total N = 841). Most studies (10 of 11) assessed attentional bias. ⋯ Overall, the findings confirm an attentional bias for headache-related stimuli among people with headache, with some evidence for interpretation bias but equivocal evidence for a memory bias. For attentional biases, eye-tracking studies found evidence for biases in initial orienting. We provide suggestions for how to extend the current research to better understand cognitive biases in chronic headache.
