Neuropathic pain (NeP) medications have several side effects that affect NeP patients' quality of life. Betanin, the most common betacyanin pigment, has been shown to have potent antioxidant and anti-inflammatory properties in vivo; thus, it has potential as a healthcare treatment. In this study, we focused on betanin (red beetroot extract) as a potential therapy for NeP. ⋯ This article supports findings of the effect of betanin on NeP and provides a potential therapeutic candidate for NeP. Furthermore, elucidating the underlying mechanism of the effect of betanin on microglial activation could assist the development of new treatments for chronic pain.

Observational Study
Seven-year follow up of Persistent Postsurgical Pain in cardiac surgery patients: a prospective observational study of prevalence and risk factors.
Our aim was to describe the long-term prevalence, risk factors and impact on quality of life of persistent postsurgical pain (PPP) following cardiac surgery. ⋯ Seven years after cardiac surgery, almost 10% of patients in this cohort described persistent pain in and around the incision. While higher than previous reports in the literature (limited to up to five post-operative years), this assessment was made following three maximal coughs and therefore is movement or function evoked. High incident of persistent postsurgical pain may adversely affect long-term quality of life which is measured using a validated tool.

Self-selected music is consistently found to be the strongest predictor for successful music listening interventions in pain management contexts, but the specific cognitive mechanisms that mediate these effects are currently unknown. ⋯ This study identifies that the act of selecting music contributes to increases in pain tolerance in parallel with the independent factor of enjoyment. This provides support for the role of cognitive agency in mediating the analgesic effects of music interventions, which suggests that people should be given as much control as possible in music interventions. Additionally, this study identifies specific individual attributes related to emotional engagement and empathy that amplify the effect of cognitive agency.

Neck and shoulder pain in adolescents seldom occur alone: results from the Norwegian Ungdata Survey.
No previous studies have investigated the prevalence of co-occurring neck/shoulder pain, other musculoskeletal pain, headache and depressive symptoms in adolescents. This study aimed to describe the prevalence of isolated neck/shoulder pain and the co-occurrence of neck/shoulder pain with other musculoskeletal pain, headache and depressive symptoms in Norwegian adolescents. ⋯ One in five adolescents reported neck/shoulder pain in this large population-based study of Norwegian adolescents. A majority of adolescents reported neck/shoulder pain in co-occurrence with other musculoskeletal pain, headache and depression. Researchers and clinicians should assess these comorbidities when assessing adolescents with neck/shoulder pain.

The use of paracetamol or nefopam for postoperative pain control is limited by the need of high doses associated with unwanted effects. Previous works suggest positive interactions between both compounds that may be exploited to obtain potentiation of antinociception. ⋯ Early postoperative pain is currently undertreated and has been recognized as a relevant source of chronic postsurgical pain. Oral efficient treatments could facilitate fast-track surgeries and patient recovery at home. Here, we identify in a mouse model of postoperative pain a potent synergistic oral combination consisting of low paracetamol and nefopam doses that provides relief of postsurgical hypersensitivity to mechanical and thermal stimuli. Oral multimodal paracetamol-nefopam mixtures represent a potential clinically available pharmacological strategy for the relief of incisional sensitivity and the promotion of patient recovery.
