Chronic pain is more prevalent in women than in men, with increasing differences between sexes in advanced age. This could be caused by differences in sex hormone levels. We therefore studied the relationship between sex hormones and the prevalence and incidence of chronic pain. ⋯ Lower sex hormone levels are associated with chronic musculoskeletal pain, independent from lifestyle and health-related factors, in community-dwelling elderly women. These results suggest that sex hormones play a role in chronic pain and should be taken into account when a patient presents with chronic pain. Therefore, sex hormones may be a potential treatment target for these patients.

Trends in long-term opioid prescribing in primary care patients with musculoskeletal conditions: an observational database study.
Long-term opioids may benefit patients with chronic pain but have also been linked to harmful outcomes. In the United Kingdom, the predominant source of opioids is primary care prescription. The objective was to examine changes in the incidence, length, and opioid potency of long-term prescribing episodes for musculoskeletal conditions in UK primary care (2002-2013). ⋯ This study has uniquely shown an increase in prescribing long-term opioids to 2009, gradually decreasing from 2011 in the United Kingdom. The trend was towards increased prescribing of controlled long-acting opioids and earlier use. Further research into the risks and benefits of opioids is required.

The impact of chronic musculoskeletal complaints (CMSC) and chronic widespread chronic musculoskeletal complaints (CWMSC) on mortality is controversial. The aim of this study was to investigate the relationship between these conditions and mortality. In this prospective population-based cohort study from Norway, baseline data from the second Nord-Trøndelag Health Survey (HUNT2, performed 1995-1997) were linked to the comprehensive National Cause of Death Registry in Norway with follow-up through the year 2011. ⋯ In the multivariate-adjusted analyses, there was no difference in all-cause mortality between individuals with or without CMSC (HR 1.01, confidence interval, 0.97-1.05) and CWMSC (HR 1.01, confidence interval, 0.96-1.05). Similarly, there was no association between CMSC or CWMSC and cardiovascular mortality, mortality from cancer, or mortality from all other causes. Therefore, from this study, we conclude that there is no evidence for a higher mortality rate among individuals with CMSC or CWMSC.

Mapping Thalamocortical Functional Connectivity in Chronic and Early Stages of Psychotic Disorders.
There is considerable evidence that the thalamus is abnormal in psychotic disorders. Resting-state functional magnetic resonance imaging has revealed an intriguing pattern of thalamic dysconnectivity in psychosis characterized by reduced prefrontal cortex (PFC) connectivity and increased somatomotor-thalamic connectivity. However, critical knowledge gaps remain with respect to the onset, anatomical specificity, and clinical correlates of thalamic dysconnectivity in psychosis. ⋯ Thalamocortical dysconnectivity is present in both chronic and early stages of psychosis, includes reduced thalamic connectivity with the executive control network, and is related to cognitive impairment.
