Randomized Controlled Trial
Cognitive exposure versus avoidance in patients with chronic pain: Adherence matters.
Behavioural exposure methods can reduce pain-avoidance behaviours, but outcomes vary. One possible explanation is that patients employ cognitive (experiential) avoidance during behavioural exposure. If so, reducing cognitive avoidance during behavioural exposure should help. One option is interoceptive exposure (IE), which involves sustained exposure (via attention) to pain sensations. In order to test if IE could improve outcomes from behavioural exposure, this study with mixed chronic pain patients compared outcomes from a cognitive behavioural therapy (CBT) pain management programme incorporating either IE or distraction from pain. ⋯ The addition of IE to behavioural exposure did not improve outcomes. However, higher adherence to either attentional strategy was associated with larger effect sizes on all measures, suggesting factors shared by the two treatments could have contributed to the outcomes. Taken as a whole, the results suggest that increasing adherence to treatment strategies, possibly by motivational measures, would improve the overall outcomes of these interventions.

The use of strong opioids is affected by various influences such as increasing emphasis on adequate pain control and increasing measures to counteract opioid abuse. This study will examine trends of analgesic strong opioid use in an older population. ⋯ Rate of analgesic strong opioid use, particularly oxycodone and buprenorphine, in this older age group increased annually. The pattern of increasing opioid use is consistent with an increased focus on pain control but may also be influenced by altered reimbursement policies and the new convenient pharmaceutical formulations.

The aim of the study was to test the hypothesis that associations with specific stress systems [hypothalamic-pituitary-adrenal (HPA) and growth hormone (GH) axes] would increase as the number of unexplained disorders increased while accounting for the possible confounding effects of psychosocial factors. ⋯ Although previous studies have shown that stress axis function acts to moderate the risk of onset of some of these disorders, the present study shows that the degree of dysfunction is not correlated with a corresponding increasing load of disorders. The uncertainty surrounding the role of these biomarkers in the aetiology of unexplained disorders needs further investigation.
