This investigation comprised information from the Danish population to analyse the development of chronic non-cancer pain (CNCP) prevalence according to sex, age, physical job demand and educational level. ⋯ This study provides an overview of the development of chronic non-cancer pain in a country and analyses the trends with socioeconomic inequalities. The continuous increasing prevalence may have huge social and economic implications. This study reveals an urgent need for measures to attenuate the increasing prevalence, which should be a priority for public health policy.

Randomized Controlled Trial
A Virtual Reality System for Pain and Anxiety Management during Outpatient Hysteroscopy- A Randomized-Control Trial.
Visual and acoustic virtual reality (VR) has been increasingly explored as a non-pharmacological tool for pain relief in clinical settings. ⋯ The use of a Virtual reality system was found ineffective in reducing pain during and after an office operative hysteroscopy without anaesthesia, in a thorough examination of both continuous physiological parameters and women's self-reported measures.

In order to decide between avoiding pain or pursuing competing rewards, pain must be assigned an abstract value that can be traded against that of competing goods. To assess the relationship between subjectively perceived pain and its value, we conducted an experiment where participants had to accept or decline different intensities of painful electric shocks in exchange of monetary rewards. ⋯ This work provides a description of the pain value function indicating how much people are willing to pay to avoid different intensities of pain. We found that the function was curvilinear, suggesting that the same unit of subjective pain has more value in the high vs. low pain range. Moreover, the pain value was influenced by the experimental manipulation of the rewards distribution and of the inter-individual differences in harm avoidance and persistence. Altogether, the present study provides a detailed account of how subjectively experienced pain is assigned value.

Pain is a clinical feature of COVID-19, however, data about persistent pain after hospital discharge, especially among ICU survivors is scarce. The aim of this study was to explore the incidence and characteristics of new-onset pain and its impact on Health-Related Quality of Life (HRQoL), and to quantify the presence of mood disorders in critically ill COVID-19 survivors. ⋯ A substantial proportion of severe COVID-19 survivors may develop clinically significant persistent pain, post-intensive care syndrome and chronic ICU-related pain. Given the number of infections worldwide and the unprecedented size of the population of critical illness survivors, providing information about the incidence of new-onset pain, its characteristics, and its influence on the patients' quality of life might help establish and improve pain management strategies.

Complex regional pain syndrome (CRPS) is an orphan disease occurring as a complication after trauma. Due to its acute onset and the typical clinical presentation of the inflammatory and autonomous signs, it is an eye-catching chronic pain disease affecting also young and working people. In social media and the internet, high pain severity and the unfavourable prognosis are often empathized. ⋯ This study compares complex regional pain syndrome (CRPS) and chronic musculoskeletal pain and questions previously reported pain, disability and lifestyle factors associated with CRPS.
