Background: Persistent low back pain is an important disability after lumbar disc surgery. Erector spinae plane block (ESPB) is highly effective in providing post-surgical pain control, but its effectiveness in long-term persistent low back pain has not been investigated. The aim of this randomized controlled trial was to investigate the effect of ESPB on the reduction of persistent low back pain after surgery.
Methods: 162 patients who were operated for lumbar disc herniation under spinal anaesthesia were divided into two groups according to the following criteria; ESPB block group (Group A); applied before surgery and 1 month after surgery and non-ESPB block group (Group B). The preoperative and postoperative 6th month Visual Analogue Scale (VAS), Oswestry Low Back Pain Disability Questionnaire (ODI) and Japan Orthopaedic Association Back Pain Evaluation Questionnaire (JOABPEQ) scores of the patients were evaluated, and it was examined whether there was a difference.
Results: In two groups with similar patient characteristics and no significant difference in preoperative pain scores, a significant improvement was observed in pain scores in Group A compared to Group B at the end of the 6th month.
Conclusions: ESPB, which has a low risk of complications and is simple to perform, has been found useful in the treatment of persistent low back pain after disc surgery.

Effect of Esketamine on Cognitive Recovery After Propofol Sedation for Outpatient Colonoscopy: A Randomized Clinical Trial.

Purpose: While esketamine shows promise as an adjunct in procedural sedation, its impact on postoperative cognitive recovery remains incompletely characterized. This study investigated the effects of esketamine on multiple dimensions of recovery, particularly cognition, in patients undergoing colonoscopy with propofol-based sedation.
Patients And Methods: We conducted this randomized, double-blinded, placebo-controlled trial from January 6, 2023, to May 20, 2024, at two hospitals in China.

Background: Pain of a chronic nature remains the foremost concern in tertiary spine clinics, yet its elusive nature and quantification challenges persist. Despite extensive research and education on low back pain (LBP), the realm of diagnostic practices lacks a unified approach. Clinically, LBP exhibits a multifaceted character, encompassing conventional assessments of severity and disability, alongside nuanced attributes like pain characterization, duration, and patient expectations.

Dysfunction of the vagus nerve has been suggested as a contributing factor in various gastrointestinal disorders, prompting interest in vagus nerve stimulation (VNS) as a non-pharmacological therapy. We performed a systematic review to determine the efficacy of invasive and non-invasive VNS in gastrointestinal disorders, including inflammatory bowel disease (IBD), irritable bowel syndrome (IBS), functional dyspepsia (FD), functional constipation, gastroesophageal reflux disease, and gastroparesis. We applied a systematic search of the literature in the PubMed, Embase, Web of Science, and Cochrane Library databases in order to identify studies comparing VNS with an adequate control condition (sham stimulation) in patients with gastrointestinal disorders.

Purpose: To investigate whether functional radiomic features in bilateral hippocampi can identify the cognitively impaired patients from low-back-related leg pain (LBLP).
Patients And Methods: For this retrospective study, a total of 95 clinically definite LBLP patients (40 cognitively impaired patients and 45 cognitively preserved patients) were included, and all patients underwent functional MRI and clinical assessments. After calculating the amplitude of low-frequency fluctuations (ALFF), regional homogeneity (ReHo), voxel-mirrored homotopic connectivity (VMHC) and degree centrality (DC) imaging, the radiomic features (n = 819) of bilateral hippocampi were extracted from these images, respectively.
