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).

It is clear that implicit motor imagery (IMI) is impaired by chronic pain in peripheral regions (hand, feet), but unclear in axial regions (neck, shoulder, back). Previous IMI tasks displayed small-amplitude movements of axial regions, which limits person-centered IMI processes mobilization. This study aimed to assess the impact of chronic low back pain (CLBP) on IMI processes with a new task displaying large-amplitude whole-body movements mobilizing the lumbar spine. ⋯ The laterality judgment task proposed here confirmed that CLBP impacts IMI processes, and that the nature of pain (neuropathic or mechanical) needs to be considered because it seems to modulate IMI processes. PERSPECTIVE: A laterality judgment task with large-amplitude lumbar movements is key to show that CLBP alters processing speed of sensorimotor information originating from the painful region. This task could become an objective tool, transferable in clinical settings, for assessing the impact and the progression of CLBP on motor control processes.

To examine whether complementary and integrative health approaches mitigate opioid prescriptions for pain and whether the relationship differs by post-dramatic stress disorder (PTSD) diagnosis, we followed 1,993,455 Veterans with musculoskeletal disorders during 2005-2017 using Veterans Healthcare Administration electronic health records. Complementary and integrative health (CIH) approaches were defined as ≥ 1 primary care visits for meditation, Yoga, and acupuncture etc using natural language processing. Opioid prescriptions were ascertained from pharmacy dispensing records. ⋯ The impact of the timing of receiving such approaches warrants further investigation. PERSPECTIVE: This article presents a quasi-experimental investigation into potential benefit of complementary and integrative health approaches (CIH) on de-prescribing opioids. The findings may potentially help clinicians who are seeking non-pharmacological alternative options to manage patient pain and opioid dependence".

It is known that smoking is associated with greater chronic pain. However, little is known about the magnitude of this relationship and its association with prescription opioid use. We examine the association between smoking status and three sets of outcomes: (1) starting and discontinuing opioids, (2) intensity of opioid use, and (3) opioid use and pain outcomes after quitting smoking. ⋯ Integrating smoking cessation into pain management programs could be highly beneficial to adults with chronic pain. PERSPECTIVE: Rarely are smoking cessation and pain management programs integrated together. We show that such integration would be highly beneficial by estimating a strong association between smoking cessation and reduced chronic pain, work limitations, and prescription opioid use.

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.
