The increasing prevalence of chronic pain and obesity has significant health and cost implications for economies in the developed and developing world. Evidence suggests that there is a positive correlation between obesity and chronic pain and the link between them is thought to be systemic inflammation. ⋯ Systemic inflammation, mechanical overload and autonomic dysfunction are associated with increased prevalence and severity of chronic pain in individuals with obesity. It has been proposed, therefore, that interventions which target systemic inflammation could help to reduce chronic pain in obese individuals. Reduction in abdominal fat has been shown to alleviate pain and reduce the systemic markers of inflammation that contribute to chronic pain. Interventions which include exercise prescription have been shown to reduce both abdominal fat and systemic inflammation. Furthermore, exercise is also known to reduce pain perception and improve mental health and quality of life which also improves pain outcomes. However, adherence to formal exercise prescription is poor and therefore exercise programmes should be tailored to the interests, needs and abilities of individuals in order to reduce attrition.

Metastatic disease is the most common malignancy of bone. Prostate, breast, lung, kidney and thyroid cancer account for 80% of skeletal metastases. Bone metastases are associated with significant skeletal morbidity including severe bone pain, pathological fractures, spinal cord or nerve roots compression, and malignant hypercalcemia. ⋯ This article aims to present these palliative treatments for the patients with bone metastases, summarize the clinical applications, and review the techniques and results. It gives an extensive overview of the possibilities of palliation in patients with metastatic cancer to bone. As such it is of interest for all physicians with no experience with these developments to make palliative procedures safer and more reliable.

The intensity of post-egg retrieval pain is underestimated, with few studies examining post-procedural pain and predictors to identify women at risk for severe pain. We evaluated the influence of pre-procedural hormonal levels, ovarian factors, as well as mechanical temporal summation (mTS) as predictors for post-egg retrieval pain in women undergoing in vitro fertilization (IVF). ⋯ Peak post-egg retrieval pain intensity was higher than anticipated. Our results suggest that post-egg retrieval pain can be predicted by baseline AMH, high peak estradiol, and OHSS. Further studies to evaluate intra- and post-procedural pain in this population are needed, as well as clinical trials to assess post-procedural analgesia in women presenting with high hormonal levels.

Opioid prescription for non-malignant pain is increasing in Europe and the US. Research and guidance have focused on the potential for dependency and medical side effects with high doses. In contrast, benzodiazepines have received little attention in the chronic pain literature, despite evidence for dependency and cognitive impairment in long term use. We aimed to examine the relationship between these classes of medication use, mood and functioning. ⋯ This study is the first to examine both opioid and benzodiazepine use together in chronic pain. We found the anticipated negative effects of opioid medication, and particularly consistent associations between benzodiazepine use and poor wellbeing. Future guidance on chronic pain prescription should focus on restricting benzodiazepine use.

To study the relationship between expected pain and future outcomes along with the moderating effects of expected pain in neuropathic pain patients. ⋯ In neuropathic pain patients whose pain does not respond to therapy, high levels of expected pain may relate to relatively lower catastrophizing scores by shifting focus away from futile attempts at "curing" pain toward focusing on achievement of more realistic personal goals.
