Background: Previous research has yielded inconsistent findings on the relationship between personality characteristics and chronic pain. The present study examines measures of alexithymia, somatosensory amplification, attachment, counterdependency, and emotional distress in 140 consecutive general medical outpatients seen in psychiatric consultation.
Methods: Forty-five subjects having no chronic pain (NP) were compared to 49 subjects with chronic pain restricted to their back and/or extremities (BE) and with 46 subjects having pain involving other regions of the body (OP).
Results: Findings demonstrated marked counterdependency traits in the BE group relative to the other two groups. By contrast, traits of alexithymia and somatosensory amplification, insecure attachment, and a high level of emotional distress characterized the OP group. A multiple logistic regression model combining counterdependency and secure attachment was 86% accurate in predicting BE (c = 0.86).
Conclusions: The study's findings suggest that personality traits vary according to chronic pain location, although the nature of the relationship still needs to be determined.

Introduction: Chronic post-thoracotomy pain (CPTP) is a persistent and disabling condition affecting a significant proportion of patients after thoracotomy and posing a challenge for clinicians, despite advances in surgical and pain management strategies. Esketamine, the S-enantiomer of ketamine, has emerged as a promising therapeutic agent for various pain conditions, with evidence for its effectiveness in alleviating acute and chronic pain. This systematic review and meta-analysis will be conducted to assess the efficacy of esketamine in treating CPTP, and evaluate its effectiveness in reducing pain intensity, improving functional outcomes, and reducing opioid consumption, as well as its adverse effects.

Introduction: Sciatica is a debilitating condition that often becomes chronic, and for which there are few effective treatment options. Treatments such as the anti-depressant duloxetine have shown promise, but the evidence is inconclusive. We are describing a high quality, definitive trial to investigate the efficacy, safety and cost-effectiveness of duloxetine in chronic sciatica.

Objectives: The objective of this study is to investigate lipopolysaccharid-binding protein (LBP), zonulin and calprotectin as markers of bacterial translocation, disturbed gut barrier and intestinal inflammation in patients with radiographic axial spondyloarthritis (r-axSpA) during tumour necrosis factor inhibitor (TNFi) therapy and to analyze the association between disease activity, response to treatment and biomarker levels.
Methods: Patients with active r-axSpA of the German Spondyloarthritis Inception Cohort starting TNFi were compared with controls with chronic back pain. Serum levels of LBP, zonulin and calprotectin were measured at baseline and after 1 year of TNFi therapy.

Background: Duloxetine, a serotonin and norepinephrine reuptake inhibitor (SNRI), is used to treat various health conditions, including major depressive disorder, generalized anxiety disorder, fibromyalgia, and off-label for chemotherapy-induced pain. We conducted this systematic review and meta-analysis aiming to test the current evidence regarding effectiveness and safety of duloxetine for postspine surgeries pain.
Methods: We searched the Cochrane Central Register of Controlled Trials, PubMed, Scopus and Web of science databases for relevant articles up to March 2024.
