Research has shown that pain is associated with disability and that depressed mood mediates the relationship between pain and disability. The question of whether duration of pain moderates these effects was addressed in this cross-sectional study with 356 chronic pain patients. ⋯ Pain duration did not moderate the direct effect of pain on disability. Implications of these findings for the treatment of chronic pain might be that targeting depressed mood is especially relevant in chronic pain patients with longer pain duration to reduce the effect of pain on disability.

Comparative StudyUpregulation of the Purinergic Receptor Subtype P2X3 in the Trigeminal Ganglion Is Involved in Orofacial Pain Induced by Occlusal Interference in Rats.
To evaluate whether the purinergic receptor subtype P2X3 (P2X3R) in trigeminal ganglion (TG) neurons is involved in hyperalgesia of the temporomandibular joints (TMJs) and masseter muscles associated with placement of an occlusal interference. ⋯ Upregulated P2X3R expression in the TG may contribute to orofacial pain development induced by an occlusal interference. P2X3R may be a therapeutic target for chronic TMJ or masseter muscle pain.

Two-thirds of older people suffer from chronic pain and finding valid treatment options is essential. In this 1-yearlong investigation, we evaluated the efficacy and safety of prolonged-release oxycodone-naloxone (OXN-PR) in patients aged ≥70 (mean 81.7) years. ⋯ This study of the long-term treatment of chronic pain in a geriatric population with OXN-PR shows satisfying analgesic effects achieved with a stable low daily dose, coupled with a good safety profile and, in particular, with a reduction of constipation, often present during opioid therapy. Our findings support the indications of the American Geriatrics Society, suggesting the use of opioids to treat pain in older people not responsive to acetaminophen or nonsteroidal anti-inflammatory drugs.

Background. Anxiety sensitivity (AS) and experiential avoidance (EA) have been shown to have an interactive effect on the response an individual has to chronic pain (CP) potentially resulting in long term negative outcomes. Objective. ⋯ Significant improvement in disability (p < 0.05) was only seen among those with lower levels of EA and AS. Conclusions. This cluster analysis demonstrated that EA had a greater influence on mood impairment, while both EA and AS levels affected disability outcomes among individuals with CP.

Pain and emotional exhaustion are prevalent conditions with consequences for sickness absence. Although they often co-occur, their combined associations with sickness absence are poorly understood. This study aimed to examine the separate and combined associations of pain and emotional exhaustion with subsequent sickness absence. ⋯ A synergistic interaction effect was found for co-occurring pain and emotional exhaustion on medically certified sickness absence. The results for men were mainly similar, but less stable. In order to tackle sickness absence, special attention should be paid to the prevention and treatment of employees with co-occurring pain and emotional exhaustion.
