Osteoarthritis (OA) represents a significant pain challenge globally, as current treatments are limited and come with substantial and adverse side effects. Voltage-gated calcium channels have proved to be pharmacologically effective targets, with multiple Food and Drug Administration-approved CaV2.2 modulators available for the treatment of pain. Although effective, drugs targeting CaV2.2 are complicated by the same obstacles facing other pain therapeutics-invasive routes of administration, narrow therapeutic windows, side effects, and addiction potential. ⋯ Together, these studies suggest that CBD3063 is an effective analgesic for OA pain. PERSPECTIVE: Despite the high prevalence of OA pain worldwide, current treatment options remain limited. We demonstrate that CBD3063-mediated disruption of the CaV2.2-collapsin response mediator protein 2 interaction alleviates pain in a preclinical joint pain model, providing a promising basis for the development of new OA pain treatments.

Previous studies have investigated the association of gender roles with pain outcomes in healthy individuals. However, little is known about this association in those with musculoskeletal (MSK) disorders. Therefore, this mixed-methods systematic review aimed to investigate the association of sociocultural gender roles on pain outcomes in adults with MSK disorders. ⋯ There is a need for pain management to evolve to acknowledge the individual pain experience through exploration of an individual's gender identity and roles. PERSPECTIVE: This article demonstrates that gender roles have a multidimensional influence on the pain experience in those with MSK disorders. These findings support the development of gender-sensitive, patient-centered approaches to pain management, acknowledging each individual's important roles and identities.

Chronic pain is prevalent among individuals with higher body weight and associated with greater impairment. As a result, weight loss is a common recommendation for pain management among those with higher body weight. Body weight is an appealing target because it is modifiable and evidence-based treatments to produce weight loss are well-established. ⋯ PERSPECTIVE: This focus article critically considers the role of weight loss in management of chronic pain among individuals of higher body. Using knee osteoarthritis as an exemplar, the evidence and clinical uptake of weight loss for pain management is reviewed. Limitations are considered to guide future research and clinical care.

Randomized Controlled Trial
Comparable conditioned pain modulation and painful-exercise-induced hypoalgesia in healthy young adults: A randomised crossover trial.
Conditioned pain modulation and exercise-induced hypoalgesia reflect inhibitory pain controls emanating from the brain. The aim of this study was to compare the extent of pain inhibition from exercise-induced hypoalgesia (isometric wall squat), conditioned pain modulation (cold-water immersion), and their combination (wall squat followed by cold water in fixed order) in healthy pain-free adults. Sixty-one participants (median age 21 years) completed 3 sessions (wall-squat, cold-water, and combined) in random order. ⋯ Pressure pain in body regions remote from the exercised or conditioned sites may be weakly modulated. PERSPECTIVE: The current findings suggest that pain-inhibitory effects induced by painful wall squat and by cold-water immersion may overlap. The magnitude of pain inhibition in the forehead remote from the exercised thigh or the conditioned foot appears smaller, which could be examined further in future research.

Both pain and mental health conditions are common among young people. They often co-occur, but we wanted to investigate further whether it is pain (abdominal pain, headache, musculoskeletal pain, menstrual pain) that precedes mental health conditions (depression, anxiety, stress, phobia) or whether it is the other way around, mental health conditions that precede pain. Using electronic health records-the Skåne Healthcare Register-we identified and followed young people aged 7 to 18 over a 13-year period and tracked all their registered diagnoses. ⋯ Compared to boys, girls had consistently higher estimates, and the same was found for the younger individuals compared to the older ones. Individuals with pain have a 3-fold increased risk of developing mental health conditions, while the risk of developing pain after mental health conditions was lower although still elevated compared to young people seeking care regardless of cause. PERSPECTIVE: Young people with pain have a 3-fold increased risk of developing mental health conditions, while the reverse risk is lower but still elevated compared to young people without these conditions. Health care professionals must recognize the interplay between pain and mental health in young patients when diagnosing and planning treatment.
