An opioid task force within an urban public health district sought to increase access to, and utilization of, non-opioid, nonpharmacologic alternatives for pain management. ⋯ Participants with chronic pain were open and willing to try a novel way to access nonpharmacologic consultations to address unmet pain needs. Virtual consultations with pain management experts may increase access to, and utilization of, complementary and integrative treatment modalities.

Background: For many cancer survivors post-cure, chronic pain is a devastating complication of cancer treatment. The prevalence of chronic pain among cancer survivors is double that of the general population. However, little is known about the pain experience of cancer survivors who may have a different perspective than people with advanced cancer or people with noncancer pain. ⋯ Conclusion and Implications: The results highlight an opportunity for pain self-management, education, and psychosocial interventions to optimize pain in cancer. Participants' experiences identify several opportunities to improve chronic cancer-related pain. Future efforts should prioritize access to multimodal pain treatments, high-quality communication, and expand clinicians' knowledge and skills to manage chronic pain.

To describe utilization patterns, negative clinical outcomes and economic burden of patients diagnosed with osteoarthritis (OA) of the hip and/or knee who received a prescription for tramadol or non-tramadol opioids vs. non-opioid drugs. ⋯ Most patients with OA of the hip and/or knee either initiate on or switch to opioids for long-term management of OA-related pain despite known risks. This highlights the need for new treatments that delay or prevent use of opioids.

Induced pluripotent stem cells (iPSCs) have enabled the generation of various difficult-to-access cell types such as human nociceptors. A key challenge associated with human iPSC-derived nociceptors (hiPSCdNs) is their prolonged functional maturation. While numerous studies have addressed the expression of classic neuronal markers and ion channels in hiPSCdNs, the temporal development of key signaling cascades regulating nociceptor activity has remained largely unexplored. ⋯ However, effective inhibition of forskolin-induced PKA-II activation by opioid receptor agonists required 70 days of in vitro differentiation. Our results identify a pronounced time difference between early expression of functionally important ion channels and emergence of regulatory metabotropic sensitizing and desensitizing signaling only at advanced stages of in vitro cultivation, suggesting an independent regulation of ionotropic and metabotropic signaling. These data are relevant for devising future studies into the development and regulation of human nociceptor function and for defining time windows suitable for hiPSCdN-based drug discovery.

ReviewRational Multimodal Analgesia for Perioperative Pain Management.
A multimodal analgesic approach improves postoperative pain relief and reduces opioid use; however, it is not universally implemented. This review presents the evidence assessing multimodal analgesic regimens and recommends optimal analgesic combinations. ⋯ The evidence for best combinations of individual patients undergoing specific procedures is lacking. Nevertheless, an optimal multimodal regimen may be determined based on identifying efficacious, safe, and inexpensive analgesics interventions. Key components of an optimal multimodal analgesic regimen include the preoperative identification of patients at high risk for postoperative pain in addition to patient and caregiver education. Unless contraindicated, all patients should receive a combination of acetaminophen, non-steroidal anti-inflammatory drug or cycoxygenase-2-specific inhibitor, dexamethasone, and procedure-specific regional analgesic technique and/or surgical site local anesthetic infiltration. Opioids should be administered as rescue adjuncts. Non-pharmacological interventions are important components of an optimal multimodal analgesic technique. It is imperative to integrate multimodal analgesia regimens within a multidisciplinary enhanced recovery pathway.
