Randomized Controlled Trial
A Randomized, Double-Blind, Double-Dummy Study to Evaluate the Intranasal Human Abuse Potential and Pharmacokinetics of a Novel Extended-Release Abuse-Deterrent Formulation of Oxycodone.
Evaluate the human abuse potential (HAP) of an experimental, microsphere-in-capsule formulation of extended-release oxycodone (oxycodone DETERx®) (herein "DETERx"). ⋯ Pharmacokinetic and pharmacodynamic outcomes suggest that DETERx IN has relatively low HAP; continued research in larger populations is suggested.

Clinical Trial
Evaluating Sativex® in Neuropathic Pain Management: A Clinical and Neurophysiological Assessment in Multiple Sclerosis.
The aim of our study was to better investigate the role of Sativex(®) in improving pain in multiple sclerosis (MS) patients by means of either clinical or neurophysiological assessment. ⋯ Our data suggest that Sativex may be effective in improving MS-related neuropathic pain, maybe through its action on specific cortical pathways.

The Pain Medication Attitude Questionnaire (PMAQ) was designed to assess concerns about pain medication among patients with chronic nonmalignant pain. The instrument has been demonstrated to be a reliable measure with good psychometric properties, yet its validity among Chinese has not been evaluated. This study aimed to translate the English-language version of the PMAQ into Chinese (ChPMAQ) and to evaluate its reliability and concurrent validity. ⋯ Despite the current preliminary findings for the reliability and concurrent validity of the ChPMAQ, more research is needed to substantiate the reliability, validity and other psychometric properties of the instrument.

Review Meta Analysis
Analgesic Efficacy and Safety of Curcuminoids in Clinical Practice: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.
Curcuminoids are natural products with potent anti-inflammatory and antioxidant properties. There have been a number of reports on the analgesic effects of curcuminoids in clinical trials, yet data have not been fully conclusive. ⋯ Curcuminoids supplements may be a safe and effective strategy to improve pain severity, by warranting further rigorously conducted studies to define the long-term efficacy and safety.

Little is known about the burgeoning Mexican American (MA) population's pain experience. ⋯ Results suggest that: 1) MAs are less likely to develop chronic pain than NHWs, 2) MAs with chronic pain report greater headache and abdominal pain than NHWs, and 3) MAs with chronic pain are less likely to use analgesic medications and other substances compared to NHWs. These results suggest that providers should consider taking extra time to discuss analgesic medications with MAs. Future investigations should examine reasons underlying these racial/ethnic differences in chronic pain, as well as differences in the use of other substances, such as marijuana.
