Randomized Controlled Trial
Psychological and neurological predictors of acupuncture effect in chronic pain patients: a randomized controlled neuroimaging trial.
Chronic pain has been one of the leading causes of disability. Acupuncture is globally used in chronic pain management. However, the efficacy of acupuncture treatment varies across patients. ⋯ Furthermore, support vector machine models applied to the questionnaire and brain features could jointly predict acupuncture improvement with an accuracy of 81.48%. Besides, the correlations and models were not significant in the sham-acupuncture group. These results demonstrate the specific psychological, brain functional, and structural predictors of acupuncture improvement and may offer opportunities to aid clinical practices.

Meta Analysis
Pain Management Interventions for the Treatment of Chronic Low Back Pain: A Systematic Review and Meta-Analysis.
Determine the relative effectiveness and safety profiles of percutaneous and minimally invasive interventions for chronic low back pain. ⋯ BVN ablation, biological therapy, and multifidus stimulation all provide significant, durable improvements in both pain and disability compared with other interventions, which provided only short-term pain relief. Studies on BVN ablation reported no SAEs, a significantly better result than for studies of biological therapy and multifidus stimulation.

Many questions regarding the clinical management of people experiencing pain and related health policy decision-making may best be answered by pragmatic controlled trials. To generate clinically relevant and widely applicable findings, such trials aim to reproduce elements of routine clinical care or are embedded within clinical workflows. In contrast with traditional efficacy trials, pragmatic trials are intended to address a broader set of external validity questions critical for stakeholders (clinicians, healthcare leaders, policymakers, insurers, and patients) in considering the adoption and use of evidence-based treatments in daily clinical care. ⋯ The meeting was organized by the Analgesic, Anesthetic, and Addiction Clinical Trial Translations, Innovations, Opportunities, and Networks (ACTTION) public-private partnership. The consensus process was informed by expert presentations, panel and consensus discussions, and a preparatory systematic review. In the context of pragmatic trials of pain treatments, we present fundamental considerations for the planning phase of pragmatic trials, including the specification of trial objectives, the selection of adequate designs, and methods to enhance internal validity while maintaining the ability to answer pragmatic research questions.

Long-term Evaluation of Spinal Cord Stimulation in Patients With Painful Diabetic Polyneuropathy: An Eight-to-Ten-Year Prospective Cohort Study.
This study aimed to evaluate the long-term effects of spinal cord stimulation (SCS) in patients with painful diabetic polyneuropathy (PDPN). ⋯ This eight-to-ten-year follow-up study indicates that SCS can remain an effective treatment in the long term to reduce pain intensity in a subcohort of patients with PDPN who still had an SCS device implanted after eight years.

Green Light-Based Analgesia - Novel Nonpharmacological Approach to Fibromyalgia Pain: A Pilot Study.
There continues to be significant reliance on pharmacological modalities for the management of chronic pain, with a particular focus on opioid analgesics as a singular option for pain management. Fibromyalgia is a prototypical central pain disorder, which is often used as a model to study chronic pain disorders. It has an estimated prevalence of approximately 1.1% to 5.4% in the general population. The widespread use of opioids in patients with fibromyalgia has been well demonstrated in several health claims database studies, with rates of use ranging from 11.3% to 69%. Minimizing opioid exposures reduces misuse risk, but requires adequate opioid-sparing multimodal analgesic strategies, particularly nonopioid analgesic adjuncts, to ensure effective treatment of pain, particularly high-impact pain. We chose fibromyalgia as our study population. Given that it is a disordered sensory processing condition, it may be particularly amenable to the beneficial effects of green-light therapy. ⋯ Our study demonstrated the feasibility of this treatment approach and study design and supports a future study to determine the efficacy of green light-based analgesia on opioid use, pain, and anxiety. While the reduction of opioid use was not of statistical significance, we believe it to be of clinical significance as there was no increase of patient-reported pain. This warrants further investigation in a large-scale trial of the use of green-light filtration of ambient light to mitigate opioid use and possible mediation of psychological impacts of pain with the use of green-lensed eyeglasses.
