Randomized Controlled Trial
Ultrasound-Guided Continuous Deep Serratus Anterior Plane Block Versus Continuous Thoracic Paravertebral Block for Perioperative Analgesia in Videoscopic-Assisted Thoracic Surgery.
The deep serratus anterior plane block (SAPB) is a promising novel regional anaesthesia technique for blockade of the anterolateral chest wall. Evidence for the efficacy of SAPB versus other analgesic techniques in thoracic surgery remains inadequate. ⋯ The SAPB interfascial plane block is an efficacious alternative method of opioid-sparing analgesia in high-risk thoracic surgical patients as part of an enhanced recovery programme.

Traditional pain interventions limit fluctuations in pain sensation, which may paradoxically impair endogenous pain modulatory systems (EPMS). However, controlled exposures to clinically relevant pain (e.g. delayed onset muscle soreness [DOMS]) may build capacity in the EPMS. Emerging evidence suggests that regional signal variability (RSV) may be an important indicator of efficiency and modulatory capacity within brain regions. This study sought to determine the role of RSV in both susceptibility to and trainability of pain response following repeated DOMS inductions. ⋯ Regional signal variability may be an important indicator of endogenous pain modulatory system responsivity to training following repeated bouts of clinically relevant pain and may in fact be responsive to training itself.

Children of individuals with chronic pain have an increased vulnerability to experience pain problems, possibly through observation of pain in their parents. As pain-related fear (PRF) is a critical factor in the development and maintenance of chronic pain, the current experimental study examined the acquisition of PRF through observational learning and subsequent extinction after first-hand experience of the feared stimulus. ⋯ Children may acquire pain-related fear by observing pain in others and this learned fear can diminish after first-hand experience. Remarkably, observational learning did not depend on the children's relationship with the model, but it did depend on the intensity of pain that is perceived. A better understanding of the impact of observing (parental) pain may help clarify the intergenerational transmission of risk for pain and inform the development of preventive programs.

Chronic pain is a common issue in adolescents. Prevalence of pain and associated factors present differently in sex and age subgroups; however, the interaction of sex and age combined has not been thoroughly assessed. This study aimed to identify psychosocial and health factors associated with chronic pain in younger and older adolescent girls and boys. ⋯ We report evidence that negative psychosocial and health factors are related to a higher prevalence of chronic pain in adolescents. Furthermore, the relationships between anxiety, socioeconomic status, lower school satisfaction and lower school performance with pain may vary between adolescents of differing sexes and ages. Understanding how possible risk factors for chronic pain contribute differently to the pain experience of adolescent girls and boys is an important step towards lowering the prevalence of this common health condition.

Review Meta Analysis
Prognostic factors for pain and functional disability in children and adolescents with persisting pain: a systematic review and meta-analysis.
The aim of this study was to investigate prognostic factors for pain and functional disability in children and/or adolescents with persisting pain. ⋯ Prognostic factors from across the biopsychosocial spectrum are important to consider in paediatric pain clinical practice. However, most prognostic factors that experts have previously agreed upon have not been assessed in prospective cohort studies to date. The findings may help with prioritising data to collect during clinical assessments of children presenting with pain, in the context of pain and functional disability outcomes.
