There is limited knowledge on the association between lifestyle behaviour in adolescence and musculoskeletal pain in young adulthood. This study aimed to investigate whether an accumulation of adverse lifestyle behaviours in adolescents with and without musculoskeletal pain at baseline, was associated with persistent musculoskeletal pain (pain duration ≥3 consecutive months the last year) 11 years later. ⋯ An accumulation of four or more adverse lifestyle behaviours in adolescents with musculoskeletal pain was associated with persistent musculoskeletal pain in young adulthood. In future health care of adolescents with musculoskeletal pain, lifestyle behaviours should be assessed, with emphasis on accumulation of multiple adverse lifestyle behaviours. Focusing on an accumulation of multiple adverse lifestyle behaviours, rather than each individual behaviour, might provide a potential area for future research and interventions targeting musculoskeletal pain in youth.

Few studies have investigated the underlying mechanisms for unilateral subacromial pain syndrome (SAPS). Therefore, this study examined (1) if 8-weeks of exercise could modulate clinical pain or temporal summation of pain (TSP), conditioned pain modulation (CPM), and exercise-induced hypoalgesia (EIH) and (2) if any of these parameters could predict the effect of 8-weeks of exercise in patients with unilateral SAPS. ⋯ This explorative study suggested reduction in pain, improved sleep quality and increased CPM after 8-weeks of exercise. Furthermore, the results suggests that low pain intensity and high TSP scores (indicative for pain sensitisation) may predict a lack of pain improvement after exercise.

Cannabigerol (CBG) is a non-psychoactive phytocannabinoid produced by the plant Cannabis sativa with affinity to various receptors involved in nociception. As a result, CBG is marketed as an over-the-counter treatment for many forms of pain. However, there is very little research-based evidence for the efficacy of CBG as an anti-nociceptive agent. ⋯ There are few effective treatments for neuropathic pain and neuropathic pain is projected to increase with the aging population. We demonstrate that CBG (cannabigerol) and CBG:CBD oil attenuate neuropathy-induced mechanical hypersensitivity mice. Second, we identify receptor targets that mediate CBG-induced reduction in mechanical hypersensitivity in neuropathic mice. Third, we demonstrate that an acute injection of CBG is anti-nociceptive specifically for neuropathic pain rather than other forms of pain, including persistent pain and thermal pain.

Endometriosis is associated with pain and impaired health-related quality of life (HRQoL). Psychosocial factors have been associated with pain and HRQoL in other conditions, suggesting their potential relevance in Endometriosis. However, the role of psychosocial factors in this population has not been systematically explored yet. This systematic review aims to explore the association of psychosocial factors with pain intensity/severity and HRQoL in women with Endometriosis. ⋯ This systematic review explored the role of psychosocial factors in Endometriosis, suggesting that these are associated with pain and health-related quality of life (HRQoL). Among the psychosocial factors included, anxiety, depression and catastrophising were the factors most often associated with pain and HRQoL in Endometriosis. These findings highlight the need to target psychological factors in the treatment of women with Endometriosis.

'Everyday' pain experiences are potentially critical in shaping our beliefs and behaviours around injury and pain. Influenced by social, cultural and environmental contexts, they form the foundation of one's understanding of pain and injury that is taken into adulthood. How to best communicate to young children about their everyday pain experiences, in order to foster adaptive beliefs and behaviours, is unknown. ⋯ Parents and caregivers likely play a critical role in the development of children's fundamental beliefs and behaviours surrounding pain and injury that are carried into adulthood. Everyday pain experiences provide key opportunities to promote positive pain-related beliefs and behaviours. This Delphi survey identified key messages and strategies that caregivers can consider to optimize learning, encourage the development of adaptive pain behaviours and build resilience for future pain experiences.
