Pain assessment and pain care are influenced by the characteristics of both the patient and the caregiver. Some studies suggest that the pain of older persons and of females may be underestimated to a greater extent than the pain of younger and male individuals. ⋯ The characteristics of the patients seem to have a greater impact on prosocial behavior and pain assessment compared to those of the observers, which bears significant implications for the treatment of pain in clinical contexts.

The longitudinal association between persistent moderate to severe pain and subsequent long-term cognitive decline remains inconclusive. ⋯ Persistent moderate to severe pain in adults age 50 and older was associated with accelerated cognitive decline over a median follow-up of 12 years. More severe pain was associated with faster cognitive decline in a dose-response pattern, and the relationship was demonstrated throughout multiple cognitive domains. While the overall effect was subtle, clinicians should be aware that older adults with persistent pain are at risk of faster cognitive decline.

Previous studies have indicated a negative correlation between GRK2 expression and pain development and transmission. Here, we investigated whether G-protein-coupled receptor kinase 2 (GRK2) was involved in regulating diabetic mechanical hyperalgesia (DMH). ⋯ GRK2 expression regulated DMH progression and is expected to play a role in the development of targeted therapy for DMH. GRK2 and Epac1 expressions play a vital role in maintaining pain in DMH rats.

Review Meta Analysis
Long-term opioid treatment and endocrine measures in chronic non-cancer pain patients: A systematic review and meta-analysis.
Long-term opioid treatment (L-TOT) of chronic non-cancer pain (CNCP) patients has been suspected to alter the endocrine system. This systematic review and meta-analysis aimed at investigating the published evidence of L-TOT effects on the endocrine system in adult CNCP patients. ⋯ This systematic review and meta-analysis suggested that long-term opioid treatment may suppress the hypothalamic-pituitary-gonadal axis, and result in lower insulin levels and alter the glucocorticoid adrenal axis in adult chronic non-cancer pain patients. This adds to the need of more research of both clinical and paraclinical outcomes and their association when initiating and maintaining long-term opioid treatment.
