Acceptance and Commitment Therapy and the psychological flexibility model on which it is based are growing interests for those researching and treating chronic pain. One part of this model is a therapeutic process called cognitive defusion. Cognitive defusion is a process of experiencing a distinction between thoughts and the events or people they describe. This process is intended to reduce the dominating psychological influence of thoughts without necessarily changing the content or frequency of the thoughts. There are recently developed measures of this process but little study of it in people with chronic pain. ⋯ The CFQ may be a useful measure for further research and treatment development.

Quantitative sensory testing (QST) has been used to elucidate the peripheral and central mechanisms that underlie changes in pain sensitivity associated with low back pain (LBP). However, it remains unclear to what degree peripheral and central changes contribute to the generation and maintenance of LBP. The aim of this study was to compare thermal pain sensitivity, measured using QST, in participants with acute LBP, chronic LBP, and pain-free controls. ⋯ We found evidence for localized and generalized cold hyperalgesia in chronic, but not acute LBP. We might speculate that hyperalgesia develops as a consequence of long-lasting LBP, but prospective studies are needed to confirm this assumption.

Multicenter Study Comparative Study Observational Study
Effectiveness of Duloxetine Compared to Pregabalin and Gabapentin in Diabetic Peripheral Neuropathic Pain: Results From A German Observational Study.
This study aimed to compare the effectiveness of duloxetine (DLX) and the anticonvulsants pregabalin (PGB) and gabapentin (GBP) for the treatment of diabetic peripheral neuropathic pain (DPNP) in routine clinical care. ⋯ When compared with DLX, the low doses of PGB and GBP used in this noninterventional study might have contributed to the lower effectiveness found for both anticonvulsants in the treatment of patients with DPNP.

Randomized Controlled Trial Multicenter Study
A Phase 2 Study of Lower-dose, Indomethacin Submicron Particle Capsules Demonstrates Early Onset of Acute Pain Relief.
Nonsteroidal anti-inflammatory drugs are efficacious for the treatment of acute and chronic pain; however, they have the potential for serious adverse events (AEs). The objective of this study was to evaluate the efficacy and safety of investigational, lower-dose, indomethacin submicron particle capsules compared with placebo in a study of patients with postsurgical pain. ⋯ Lower-dose, indomethacin submicron particle capsules provide good overall pain relief in patients with postsurgical pain and are generally well tolerated. Indomethacin submicron particle capsules are a potentially promising option for treatment of acute pain and warrant further study.

Previous studies have suggested that many inflammatory cytokines, including interleukin (IL)-1α, may be associated with lumbar radicular pain after disk herniation. In the present study, we examined how variability of the IL-1α gene affects pain intensity and the pressure pain threshold (PPT) in patients with symptomatic disk herniation. ⋯ The present data show that the IL-1α CT/TT genotype rs1800587 may be associated with increased pain intensity and corresponding reduced PPT during the first year after disk herniation.
