Persistent breast cancer treatment-related pain affects up to 40% of patients, decreasing their quality of life (QoL). While current research typically utilizes correlation and regression analysis to identify biopsychosocial phenotypes contributing to this pain, this study employs cluster analysis to identify qualitatively different phenotypes based on somatosensory and psychosocial characteristics both before and one week post-breast cancer surgery. Further, it investigates how these phenotypes are related to pain intensity one year post-surgery and examines the evolution of phenotype membership from pre- to post-surgery. ⋯ PERSPECTIVE: This secondary analysis, utilizing cluster analysis, reveals five distinct phenotype based on somatosensory and psychosocial characteristics both before and post-breast cancer surgery. Higher psychosocial distress and lower quality of life correlated with elevated pain intensity one year post-surgery, emphasizing the need to address patients' mental health perioperatively. TRIAL REGISTRATION: clinicaltrials.gov (NCT03351075).

Artificial intelligence (AI) represents an exciting and evolving technology that is increasingly being utilized across pain medicine. Large language models (LLMs) are one type of AI that has become particularly popular. Currently, there is a paucity of literature analyzing the impact that AI may have on trainee education. As such, we sought to assess the benefits and pitfalls that AI may have on pain medicine trainee education. Given the rapidly increasing popularity of LLMs, we particularly assessed how these LLMs may promote and hinder trainee education through a pilot quality improvement project. ⋯ AI represents a continually evolving and promising modality to assist trainees pursuing a career in pain medicine. Still, limitations currently exist that may hinder their independent use in this setting. Future research exploring how AI may overcome these challenges is thus required. Until then, AI should be utilized as supplementary tool within pain medicine trainee education and with caution.

Pain is a very common complaint among patients with hypermobile Ehlers-Danlos Syndrome (hEDS) and Hypermobility Spectrum Disorders (HSDs). Often challenging to treat, insights into the underpinnings of pain in this population have been fleeting. Central sensitization (CS) has been postulated as a potential etiological factor. ⋯ A large percentage of patients with pain and a diagnosis of hEDS/HSDs demonstrated evidence of central sensitization as measured using the CSI. The CSI is simple to administer. The CSI may provide clinical insights that are key to successfully managing patients with hEDS/HSDs. Further research is needed to explore the ability to classify pain phenotypes in this patient population and the impact on precision medicine.

Does cytochrome 2D6 genotype affect the analgesic efficacy of codeine after ambulatory surgery? Prospective trial in 987 adults.
Paracetamol-codeine combination tablet is widely used in pain management after day surgery. For safety reasons, its use has decreased in recent years. Codeine is a prodrug metabolised in the liver by the cytochrome P450 2D6 (CYP2D6) enzyme to morphine that produces the analgesic effect of codeine. CYP2D6 is highly polymorphic, and based on genotypes, individuals can be divided into four categories: poor-, intermediate-, normal- and ultrarapid metabolisers. Differences in morphine and its metabolite concentrations have been described between different CYP2D6 genotypes following codeine administration. The aim of the study was to investigate the possible effect of CYP2D6 genotype on codeine efficacy and adverse effects in a large cohort of adult patients undergoing ambulatory surgery. ⋯ CYP2D6 genotype appears to be of minor importance for the analgesic efficacy of oral paracetamol-codeine combination therapy after ambulatory surgery in adult patients undergoing similar types of surgery as in the present study but it may affect the risk of constipation.

Kratom (Mitragyna speciosa) is increasingly used in the US for self-management of pain, despite limited research on its efficacy and safety. To better understand how and why people use kratom for pain self-management, we analyzed baseline survey data (N = 395) and 15-day ecological momentary assessment (EMA) data (N = 357) from kratom consumers across the US. Although we recruited participants based on their kratom use, not on whether they used it for pain management, nearly half (49.1 %) met criteria for chronic pain, with many reporting substantial pain relief and high effectiveness of kratom in managing pain. ⋯ These findings underscore the urgent need for systematic, rigorous research on long-term implications, efficacy, and safety of kratom in pain management to guide informed clinical practices and regulatory policies. PERSPECTIVE: This study reveals that chronic pain is common among kratom consumers, who frequently use it for pain self-management and report significant relief, as shown by ecological momentary assessment. There is an urgent need for research into kratom's safety, efficacy, and mechanisms to guide clinical practice and inform policies.
