Virus-mediated gene delivery shows promise for the treatment of chronic pain. However, viral vectors have cytotoxicity. To avoid toxicities and limitations of virus-mediated gene delivery, we developed a novel nonviral hybrid vector: HIV-1 Tat peptide sequence modified with histidine and cysteine residues combined with a cationic lipid. ⋯ The effect was reversible with local naloxone administration. We quantified β-endorphin secretion from HSC-3 cells and showed that HSC-3 cells transfected with OPRM1 secreted significantly more β-endorphin than control HSC-3 cells. These findings indicate that nonviral delivery of the OPRM1 gene targeted to the cancer microenvironment has an analgesic effect in a preclinical cancer model, and nonviral gene delivery is a potential treatment for cancer pain.

Clinical TrialDigital Pills to Measure Opioid Ingestion Patterns in Emergency Department Patients With Acute Fracture Pain: A Pilot Study.
Nonadherence to prescribed regimens for opioid analgesic agents contributes to increasing opioid abuse and overdose death. Opioids are frequently prescribed on an as-needed basis, placing the responsibility to determine opioid dose and frequency with the patient. There is wide variability in physician prescribing patterns because of the lack of data describing how patients actually use as-needed opioid analgesics. Digital pill systems have a radiofrequency emitter that directly measures medication ingestion events, and they provide an opportunity to discover the dose, timing, and duration of opioid therapy. ⋯ The digital pill is a feasible method to measure real-time opioid ingestion patterns in individuals with acute pain and to develop real-time interventions if opioid abuse is detected. Deploying digital pills is possible through the ED with a short instructional course. Patients who used the digital pill accepted the technology.

The challenge of responding to prescription opioid overuse within the United States has fallen disproportionately on the primary care clinic setting. Here we describe a framework comprised of 6 Building Blocks to guide efforts within this setting to address the use of opioids for chronic pain. ⋯ In response to prescription opioid overuse and the resulting epidemic of overdose and addiction, primary care clinics are making improvements driven by a common set of best practices that address complex challenges of managing COT patients in primary care settings.

Multicenter Study
A Multicenter Evaluation of Emergency Department Pain Care Across Different Types of Fractures.
To identify differences in emergency department (ED) pain-care based on the type of fracture sustained and to examine whether fracture type may influence the more aggressive analgesic use previously demonstrated in older patients. ⋯ Long bone fractures were associated with more aggressive pain care than SBF. When fracture types were examined separately, older patients did not appear to receive more aggressive pain care. This difference should be accounted for in further research.

ReviewPharmacology and Perioperative Considerations of Pain Medications.
Pain continues to be the most common medical concern, and perioperative health care providers are encountering increasing numbers of patients with chronic pain conditions. It is important to have a clear understanding of how long-term use of pain medications impacts anesthesia during the intraoperative and postoperative periods. ⋯ Management of postoperative pain is an important concern for all perioperative health care providers. Although most pain medications should be continued in the perioperative period, it is important to preoperatively discontinue those that antagonize pain receptors to avoid significant postoperative morbidities associated with poorly managed pain.
