Clinical Trial
SCN9A Variants may be Implicated in Neuropathic Pain Associated with Diabetic Peripheral Neuropathy and Pain Severity.
Previous studies have established the role of SCN9A in various pain conditions, including idiopathic small fiber neuropathy. In the present study, we interrogate the relationship between common and rare variants in SCN9A gene and chronic neuropathic pain associated with diabetic peripheral neuropathy. ⋯ The association of SCN9A variants with neuropathic pain and pain severity suggests a role of SCN9A in the disease etiology of neuropathic pain.

Previous research indicates that reducing fear of movement-related pain is hampered by engaging in safety-seeking behavior. We tested the hypothesis that fear reduction is only disrupted by behavior that serves a pain-avoidance goal (safety-seeking), but not when it is serving an achievement goal. ⋯ These results highlight the importance of motivational context in understanding the role of safety-seeking behavior in exposure-based therapies.

Randomized Controlled Trial Multicenter Study
Efficacy and Safety of Pregabalin in the Treatment of Patients With Painful Diabetic Peripheral Neuropathy and Pain on Walking.
This randomized, double-blind, placebo-controlled, multicenter, 2-period crossover study (two 6-week treatment periods separated by a 2-week washout period) evaluated the efficacy and safety of pregabalin (150 to 300 mg/d) for treatment of pain and pain on walking in patients with painful diabetic peripheral neuropathy (DPN) who experienced pain while walking. ⋯ Failure to meet the co-primary objectives may be related to carryover effect from period 1 to period 2, lower pregabalin dose (150 to 300 mg/d), and/or placebo response in painful DPN.

Randomized Controlled Trial
Relationships among Adverse Events, Disease Characteristics, and Demographics in Treatment of Postherpetic Neuralgia with Gastroretentive Gabapentin.
To characterize risk factors for occurrence of adverse events (AEs) and treatment discontinuations due to AEs for improving safety and tolerability of treatment of postherpetic neuralgia (PHN). ⋯ The tolerability of G-GR was not affected by patient age, but was affected by AE severity. Although being female was predictive of reporting AEs, it did not influence treatment discontinuation. Given that PHN is a disease for which the risk and duration of PHN increases with age and with being female, G-GR appears to be a well-suited treatment option for PHN.

Randomized Controlled Trial
Efficacy and Cost-effectiveness of Acceptance and Commitment Therapy and Applied Relaxation for Longstanding Pain: A Randomized Controlled Trial.
To date, few studies have compared Acceptance and Commitment Therapy (ACT) for longstanding pain with established treatments. Only 1 study has evaluated the cost-effectiveness of ACT. The aim of the current study was to evaluate the efficacy and cost-effectiveness of ACT and applied relaxation (AR) for adults with unspecific, longstanding pain. ⋯ More studies investigating moderators and mediators of change are needed. The present study is one of few that have evaluated the cost-effectiveness of ACT and AR and compared ACT with an established behavioral intervention, and the results provide additional support for behavioral interventions for longstanding pain.
