Background: The continuous infusion of ropivacaine is effective in controlling pain for a wide variety of surgical procedures and reducing opioid adverse effects and dependency. The present study assessed the efficacy of ropivacaine infusion using the I-Flow dual Soaker Catheter system at the surgical site for bariatric surgery recovery at the Dallas Veterans Affairs Medical Center Hospital (Dallas, TX). We hypothesized that patients receiving ropivacaine would report lower levels of morphine requirement and pain, would have shorter hospital stays, and would return to ambulating faster than patients in the control group.
Methods: A total of 45 patients undergoing Roux-en-Y gastric bypass surgery were randomized to 1 of 2 treatment groups, with a target study population of 50 patients, receiving either .2% ropivacaine (n = 24) or saline solution (n = 21). Before incision closure, the surgeon infiltrated the surrounding tissues with 30 mL of ropivacaine (.5%) or saline solution. The catheter was then placed in both the subfascial space and subcutaneously. Next, the infusion pump was connected to the Soaker Catheters to complete the system design and deliver solution to the surgical site.
Results: No significant differences were found in the pain scores, morphine requirement, or length of stay between the 2 groups. The ropivacaine group interval to sitting up was one half day shorter than that of patients receiving saline (P = .038).
Conclusions: Patients receiving ropivacaine were found to ambulate much more quickly than did the control group patients. This could be very beneficial in reducing the complications from blood clots and improving patient recovery and overall well-being after surgery by assisting with a quicker return to activities of daily living and reducing the dependence on the nursing staff.

IgG4-related disease (IgG4-RD) is an immune-mediated disorder characterized by organ enlargement and dysfunction. The formation of tertiary lymphoid tissues (TLTs) in affected organs is crucial for understanding IgG4-RD, as T follicular helper (Tfh) 2 cells within TLTs drive IgG4+B cell differentiation, contributing to mass formation. Key cytokines IL-4 and IL-10, produced by Tfh2 cells, are essential for this process.

Background And Objectives: Radical prostatectomy is a standard treatment for prostate cancer, yet about 30% of patients experience rising biochemical markers within a decade post-surgery. Pelvic lymph node sampling during prostatectomy assesses potential lymph node metastases, but standard histological assessments, which typically examine only 2-3 tissue sections, often miss occult metastases. This study assesses the effectiveness of qPCR in detecting PSA coding KLK3 mRNA for identifying lymph node metastases post-prostatectomy and explores the correlation between PSA-mRNA and biochemical recurrence.

Methods: To determine whether combination nonopioid analgesics are at least as good as opioid analgesics, a multisite, double-blind, randomized, stratified, noninferiority comparative effectiveness trial was conducted, which examined patient-centered outcomes after impacted mandibular third-molar extraction surgery.

Objectives: Past studies have shown the efficacy of spinal targeted drug delivery (TDD) in pain relief, reduction in opioid use, and cost-effectiveness in long-term management of complex chronic pain. We conducted a survey to determine treatment variables associated with patient satisfaction.
Materials And Methods: Patients in a single pain clinic who were implanted with Medtronic pain pumps to relieve intractable pain were identified from our electronic health record.
