This study aimed to examine the relationship between cognitive factors (cognitive fusion and catastrophizing) and functional limitation experienced by patients with fibromyalgia across different levels of pain severity (i.e., moderation). ⋯ The results suggest that in interventions to improve functioning in people with fibromyalgia, some maladaptive forms of thought management (i.e., cognitive fusion and magnification) preferably should be challenged at milder levels of pain severity. According to our findings, cognitive fusion and magnification might have less room to impact functioning at higher levels of pain severity; therefore, rumination and helplessness, which had comparable associations with functioning irrespective of pain levels, would be preferable targets in psychological interventions in patients with fibromyalgia experiencing more severe pain levels.

Randomized Controlled Trial
A Phase 1, Randomized, Double-blind, Placebo-controlled, Crossover Study to Evaluate the Pharmacodynamic Effects of VX-150, a highly selective NaV1.8 inhibitor, in Healthy Male Adults.
To evaluate the analgesic potential, safety, tolerability, and pharmacokinetics of VX-150, a pro-drug of a highly selective NaV1.8 inhibitor, in healthy subjects. ⋯ Results of this proof-of-mechanism study are supportive of the potential of VX-150, a highly selective NaV1.8 channel inhibitor, to treat various pain indications.

Observational Study
Temporal association of pain catastrophizing and pain severity across the perioperative period: a cross-lagged panel analyses following total knee arthroplasty.
Although numerous studies show that preoperative pain catastrophizing is a risk factor for pain after total knee arthroplasty (TKA), little is known about the temporal course of the association between perioperative pain catastrophizing and pain severity. The present study investigated temporal changes and their dynamic associations between pain catastrophizing and pain severity before and after TKA. ⋯ We provide evidence that changes in pain catastrophizing from baseline to 6 weeks after TKA are associated with subsequent pain severity. Future studies are warranted to determine whether targeting pain catastrophizing during the perioperative period may improve clinical outcomes for individuals undergoing TKA.
