AI Article Synopsis

  • Traditional radiofrequency ablation (TRFA) and water-cooled radiofrequency ablation (CRFA) are both effective treatments for facet joint-related pain, with CRFA offering potential advantages like larger lesion size and easier access to nerves.
  • The study analyzed 346 RFA interventions on 190 patients with chronic low-back pain and found that both treatments achieved significant pain relief, with CRFA showing slightly better results at the first follow-up.
  • At the second follow-up, CRFA maintained effectiveness, while TRFA showed improvement but less than CRFA, and pain relief in both groups declined by the third follow-up.

Article Abstract

Traditional radiofrequency ablation (TRFA) effectively treats facet joint-related pain, while water-cooled radiofrequency ablation (CRFA) may offer benefits like larger lesions and easier nerve access. Our goal is to assess the effectiveness of TRFA and CRFA for facet joint-related pain. This retrospective study included an evaluation of 346 RFA interventions performed on 190 patients suffering from long-term low-back pain. The primary outcome was defined as a decrease of ≥50% of the mean numeric rating scale. The primary outcome was achieved at the first follow-up (FU) for both TRFA and CRFA, with pain relief of 55.2 and 60.5%, respectively. At the second FU, the primary outcome was achieved only in the CRFA group (54.1%), although the TRFA group also showed a good improvement (48.6%). In both groups, pain relief was under 50% during the third FU. Our study indicates that both CRFA and TRFA modalities are effective and safe treatments.

Objective: This study aimed to evaluate and compare the clinicopathologic features of primary fallopian tubal carcinoma (PFTC) and high-grade serous ovarian cancer (HGSOC) and explore the prognostic factors of these two malignant tumors.

Methods: Fifty-seven patients diagnosed with PFTC from 2006 to 2015 and 60 patients diagnosed with HGSOC from 2014 to 2015 with complete prognostic information were identified at Women's Hospital of Zhejiang University. The clinicopathological and surgical data were collected, and the survival of the patients was followed for 5 years after surgery.

Background: The potential therapeutic role of magnesium (Mg) in type 2 diabetes mellitus (T2DM) remains insufficiently studied despite its known involvement in critical processes like lipid metabolism and insulin sensitivity. This study examines the impact of Mg-focused nutritional education on lipid profile parameters, total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C) in T2DM patients.

Methods: Thirty participants with T2DM were recruited for this within-subject experimental study.

Background: Delta large-channel endoscopy and unilateral biportal endoscopy (UBE) are prominent minimally invasive techniques for treating lumbar spinal stenosis, known for minimal tissue damage, clear visualization, and quick recovery. However, rigorous controlled research comparing these procedures is scarce, necessitating further investigation into their respective complications and long-term effectiveness. This randomized controlled trial aims to compare their perioperative outcomes, focusing on postoperative recovery and complications over time.

Background: Postoperative delirium (POD) is the most common neurological adverse event among elderly patients undergoing surgery. POD is associated with an increased risk for postoperative complications, long-term cognitive decline, an increase in morbidity and mortality as well as extended hospital stays. Delirium prevention and treatment options are currently limited.
