Randomized Controlled Trial Multicenter Study
Yoga, Eurythmy Therapy and Standard Physiotherapy (YES-Trial) for Patients with Chronic Non-specific Low Back Pain: a Three-Armed Randomized Controlled Trial.
We aimed to evaluate the effects of yoga and eurythmy therapy compared to conventional physiotherapy exercises in patients with chronic low back pain. In a three-armed, multicentre, randomized controlled trial, patients with chronic low back pain were treated for 8 weeks in group sessions (75 minutes once per week). Primary outcome was patients' physical disability (measured by RMDQ) from baseline to week 8. ⋯ Clinical Trials Register: DRKS-ID: DRKS00004651 Perspective: This article presents the results of a multicentre three-armed randomized controlled trial on the clinical effects of three 8-week programs in patients with chronic low back pain. Compared to the 'gold standard' of conventional physiotherapeutic exercises, eurythmy therapy and yoga therapy lead to comparable symptomatic improvements in patients with chronic low back pain. However, the within-group effect sizes were small to moderate and did not reach clinical meaningfulness on patients' physical disability (RMDQ).

Observational Study
PREDICTORS OF SICKNESS ABSENCE IN A CLINICAL POPULATION WITH CHRONIC PAIN.
Chronic pain-related sickness absence is an enormous socioeconomic burden globally. Optimized interventions are reliant on a lucid understanding of the distribution of social insurance benefits and their predictors. This register-based observational study analyzed data for a 7-year period from a population-representative sample of 44,241 chronic pain patients eligible for interdisciplinary treatment (IDT) at specialist clinics. ⋯ Information on these features could guide personalized intervention in the specialized healthcare. PERSPECTIVE: This study describes sickness absence in patients who visited a Swedish pain specialist interdisciplinary treatment clinic during the period 2005 to 2016. Predictors of future sickness absence are also identified that should be considered when adapting IDT programs to the patient's needs.

High molecular weight hyaluronan (HMWH), a prominent component of the extracellular matrix binds to and signals via multiple receptors, including cluster of differentiation 44 (CD44) and toll-like receptor 4 (TLR4). We tested the hypothesis that, in the setting of inflammation, HMWH acts at TLR4 to attenuate hyperalgesia. We found that the attenuation of prostaglandin E2 (PGE2)-induced hyperalgesia by HMWH was attenuated by a TLR4 antagonist (NBP2-26245), but only in male and ovariectomized female rats. ⋯ This treatment completely reversed HMWH-induced anti-hyperalgesia in male rats. Our results demonstrate a sex hormone-dependent, sexually dimorphic involvement of TLR4 in HMWH-induced anti-hyperalgesia, that is MyD88 dependent. PERSPECTIVE: The role of TLR4 in anti-hyperalgesia induced by HMWH is a sexually dimorphic, TLR4 dependent inhibition of inflammatory hyperalgesia that provides a novel molecular target for the treatment of inflammatory pain.

Review Meta Analysis
Prevalence and interference of chronic pain among people with haemophilia: A systematic review and meta-analysis.
Chronic pain is a common condition among people with hemophilia (PWH), associated with joint deterioration due to repeated joint bleeds. This systematic review and meta-analysis aimed to determine the prevalence of chronic pain due to haemophilia and to analyze its interference in the lives of patients. A systematic search was performed in May and June 2019 and updated in February 2021, using PubMed, EMBASE, Web of Science and SciElo. ⋯ Research in the hemophilia field should clearly distinguish between acute and chronic pain and provide complete characterization of study samples. PERSPECTIVE: Pain is a central issue in the lives of people with hemophilia, posing a significant challenge for healthcare providers. A clear picture of chronic pain due to hemophilia is precluded by high heterogeneity among studies and various definitions used to investigate its prevalence.

The failure of past practices and policies related to opioid prescribing for chronic pain has led federal agencies and professional organizations to recommend multimodal approaches that prioritize evidence-based nonpharmacological pain treatments (NPTs). These multimodal approaches, which include both traditional and complementary/integrative approaches, hold great promise for reducing the burden of chronic pain and reducing opioid use. ⋯ Despite these dual crises of chronic pain and opioid use in the U. S., there has never been a concerted effort to broadly educate the American public about these issues and NPT pain management options.
