Comorbid symptoms in fibromyalgia (FM) syndrome, such as mood disorders and cognitive dysfunction, may lead to greater functional impairment than pain itself. This study aimed to unravel the modulating role of depression in response execution and inhibition in FM using an emotional go/no-go task. ⋯ Taken together, these results add evidence to the notion that depression is associated with higher affective dysregulation and deficit of information-processing speed in FM. Furthermore, our data suggest that pain induces a bias to pain-related information, but the absence of significant group differences in event-related potential amplitudes, calculated with analyses of covariance (ANCOVA) (with pain intensity), seem to show that pain intensity is not a predictor for cognitive dysfunctions.

A patient's personal interpretations of a health threat or "illness perceptions" (IPs) are associated with their clinical outcomes. This study explored whether IPs are associated with pain severity and ability to modulate pain in women with chronic pelvic pain syndrome (CPPS), as well as the predictive value of IPs on myofascial manual therapy (MMT) success. ⋯ Cognitive representations play a unique role in CPPS expression and MMT outcomes. The interplay between negative IPs and a pronociceptive modulation profile, mediated by enhanced facilitatory and reduced inhibitory processes, may be involved in the manifestation of CPPS.

Dexmedetomidine has been shown to have an analgesic effect. However, no consensus was reached in previous studies. ⋯ Intravenous DEX effectively relieved the pain intensity, extended the pain-free period, and decreased the consumption of opioids during postoperative recovery of adults in general anesthesia.

Both pediatric and parent pain catastrophizing and pain acceptance are key factors associated with pediatric pain outcomes; however, the interactive effects of these factors within the parent-child dyad have yet to be tested. The aims of this study were to examine: (1) the mediating role of child catastrophizing between parent catastrophizing and child outcomes (pain interference and mobility), (2) the mediating role of child acceptance between parent acceptance and child outcomes, and (3) whether child acceptance buffers the relation between parent catastrophizing and child catastrophizing, which in turn impacts child outcomes. ⋯ The findings of this study highlight the need for caregiver involvement in multidisciplinary treatments to mitigate risk and enhance resilience in youth with chronic pain.

This cross-sectional study examined the associations among optimism, psychological resilience, endogenous pain inhibition, and clinical knee pain severity. Two hypotheses were tested. First, we hypothesized that experimentally tested endogenous pain inhibition would mediate the relationship between optimism and clinical knee pain severity. Second, it was also hypothesized that optimism would moderate the relationships of psychological resilience with endogenous pain inhibition and clinical knee pain severity, particularly for individuals with high optimism. ⋯ This study suggests that an optimistic outlook may beneficially impact clinical pain severity by altering endogenous pain modulatory capacity. Furthermore, individuals with low optimism (ie, pessimists) may be more adept at engaging resources that promote psychological resilience, which in turn, enhances endogenous pain modulatory capacity. Therefore, this study supports consideration of psychological resilience factors when evaluating experimental and clinical pain outcomes.
