Randomized Controlled Trial
Treatment Goals and Preferences of Black Veterans with Chronic Musculoskeletal Pain.
Understanding patient goals and preferences is critical in the context of complex conditions such as chronic pain. This need may be especially pronounced for Black patients, who experience significant health and healthcare disparities. The primary aim of this study was to describe the treatment goals and preferences of Black veterans with chronic musculoskeletal pain who were enrolled in the intervention arm of a randomized controlled trial testing a coaching intervention. ⋯ Most patients prioritized goals to improve physical functioning, pain severity, and participation in valued activities. Patients primarily preferred non-pharmacological treatments. This emphasizes the need for clear communication with Black patients regarding pain-related goals and non-pharmacological treatment options.

Breast cancer patients experience treatment-related pain from surgery, radiation, chemotherapy, and long-term hormonal treatment, which can lead to poorer outcomes. Patient and family caregivers' psychosocial distress exacerbates patient pain interference, but this has not been directly examined among breast cancer patients in dyadic models longitudinally. Guided by a biopsychosocial framework, the Biobehavioral Family Model, we explore how multiple reports of patient pain interference across the first year of treatment are linked to the patient (N = 55) and caregiver (N = 55) pretreatment psychosocial distress (eg, depression, anxiety, marital satisfaction, family relationship quality). ⋯ Thus, caregivers' psychosocial distress (ie, anxiety and marital satisfaction) may be a particularly important target in future dyadic behavioral intervention strategies to reduce breast cancer patient pain. PERSPECTIVE: This article presents the link between breast cancer patients and family caregiver pretreatment psychosocial distress (anxiety, depression, marital satisfaction, and family quality) on patient pain interference during 1 year of breast cancer treatment. Findings suggest that caregiver anxiety and marital satisfaction may be important targets for future dyadic behavioral pain interventions.

Previous studies have established a core outcome set for pediatric chronic pain clinical trials. The aim of this research was to establish which outcomes young people and parents considered important to measure during treatment for chronic musculoskeletal pain. To the best of our knowledge, this is the first study to explore which outcomes could be used to tailor interventions within a clinical setting. ⋯ Overall, the research highlighted the need for clinical guidance on which outcome domains to measure during the treatment course to gauge treatment effectiveness and optimally tailor interventions. PERSPECTIVE: This study established the range of outcomes that were important to young people and their parents during treatment for chronic musculoskeletal pain. The findings show how young people and parents have different outcome preferences and how their outcome focus changes during the treatment course.

The measurement of withdrawal to experimenter-delivered mechanical stimuli (von Frey test) and to heat stimuli (radiant heat paw-withdrawal or Hargreaves' test) applied to the hind paws is ubiquitous in preclinical pain research, but no normative values for the most-common applications of these tests have ever been published. We analyzed a retrospective data set of withdrawal thresholds or latencies in 8,150 mice in which these measures were taken using replicate determinations, before and after injection of inflammatory substances or experimental nerve damage producing pain hypersensitivity, totaling 97,332 measurements. All mice were tested in the same physical laboratory over a 20-year period using similar equipment and procedures. ⋯ These factors are discussed, and we believe that these normative data will serve as a useful reference for expected values in preclinical pain testing. PERSPECTIVE: This article presents a retrospective analysis of a large data set of mouse von Frey and radiant heat paw-withdrawal (Hargreaves' test) measurements collected in a single laboratory over 20 years. In addition to serving as a normative guide, sources of variability are identified including genotype, tester, and sex.

Oxaliplatin-induced peripheral neuropathy (OIPN) is a dose-limiting toxicity characterised by mechanical allodynia and thermal hyperalgesia, without any licensed medications. ART26.12 is a fatty acid-binding protein (FABP) 5 inhibitor with antinociceptive properties, characterised here for the prevention and treatment of OIPN. ART26.12 binds selectively to FABP5 compared to FABP3, FABP4, and FABP7, with minimal off-target liabilities, high oral bioavailability, and a NOAEL of 1,000 mg/kg/day in rats and dogs. ⋯ These results show promise that ART26.12 is a safe and well-tolerated candidate for the treatment and prevention of OIPN through lipid modulation. PERSPECTIVE: Inhibition of fatty acid-binding protein 5 (FABP5) is a novel target for reducing pain associated with chemotherapy. ART26.12 is a safe and well-tolerated small molecule FABP5 inhibitor effective at preventing and reducing pain induced with oxaliplatin through lipid modulation and activation of cannabinoid receptors.
