Background: Palmitoylethanolamide (PEA) belong to endocannabinoid family, a group of fatty acid amides. PEA has been proven to have analgesic and anti-inflammatory activity and has been used in several controlled studies focused on the management of chronic pain among adult patients with different underlying clinical conditions.
Methods/design: A literature search will be performed using PubMed, EMBASE, and the Cochrane Central Register of Controlled Trials (CENTRAL). The population will be patients who have chronic pain, the intervention will be the administration of PEA alone or in combination with other drugs for the pain management; the comparison will be the standard therapy in accordance with the current guidelines for the treatment of pain. The Outcomes will be the reduction of pain not restricted to specific scales laying out the pain outcome data described in the included studies.
Discussion: This scoping review aims to describe the clinical applications of the PEA in chronic pain management and its outcome.

Rapid declines in opioid analgesics dispensed in American communities since 2011 raise concerns about inadequate access to effective pain management among patients for whom opioid therapies are appropriate, especially for those living in racial/ethnic minority and socioeconomically deprived communities. Using 2011 to 2021 national data from the Automated Reports and Consolidated Ordering System and generalized linear models, this study examined quarterly per capita distribution of oxycodone, hydrocodone, and morphine (in oral morphine milligram equivalents [MMEs]) by communities' racial/ethnic and socioeconomic profiles. Communities (defined by 3-digit-zip codes areas) were classified as "majority White" (≥50% self-reported non-Hispanic White population) vs "majority non-White.

Unlabelled: The association of the pathogenesis of neurodegenerative diseases, depression, anxiety, and cognitive disorders with neurotrophin-3 deficiency determines the prospect of creating drugs with a similar mechanism of action. Since the use of full-length NT-3 is limited by unsatisfactory pharmacokinetic properties, the creation of low-molecular mimetics of neurotrophin-3 that are active when administered systemically is relevant. The Federal Research Center for Innovator and Emerging Biomedical and Pharmaceutical Technologies has created a dimeric dipeptide mimetic of the 4th loop of NT-3, hexamethylenediamide bis-(N-γ-oxybutyryl-L-glutamyl-L-asparagine) with the laboratory code GTS-302, which activates TrkC and TrkB receptors.

Background: Total knee arthroplasty (TKA) is associated with moderate to severe postoperative pain. Pain control is crucial for rapid mobilisation and reduces side effects as well as the length of hospital stay. In this context, a variety of multimodal pain control regimes show good pain relief, including several nerve blocks, iPACK and local infiltration analgesia (LIA).

Purpose Of Review: Chronic pain is highly prevalent and involves a complex interaction of sensory, emotional, and cognitive processes, significantly influenced by ambient temperature. Despite advances in pain management, many patients continue to experience inadequate pain relief. This review aims to consolidate and critically evaluate the current evidence on the impact of ambient temperature on chronic pain conditions such as fibromyalgia (FM), multiple sclerosis (MS), complex regional pain syndrome (CRPS), and osteoarthritis (OA).

Purpose Of Review: Artificial intelligence (AI) offers a new frontier for aiding in the management of both acute and chronic pain, which may potentially transform opioid prescribing practices and addiction prevention strategies. In this review paper, not only do we discuss some of the current literature around predicting various opioid-related outcomes, but we also briefly point out the next steps to improve trustworthiness of these AI models prior to real-time use in clinical workflow.
Recent Findings: Machine learning-based predictive models for identifying risk for persistent postoperative opioid use have been reported for spine surgery, knee arthroplasty, hip arthroplasty, arthroscopic joint surgery, outpatient surgery, and mixed surgical populations.
