Enhanced Antibiotic Release and Mechanical Strength in UHMWPE Antibiotic Blends: The Role of Submicron Gentamicin Sulfate Particles.
J Bone Joint Surg Am
January 2025
Harris Orthopaedics Laboratory, Massachusetts General Hospital, Boston, Massachusetts.
Background: Periprosthetic joint infections (PJIs) are a major complication of total joint replacement surgeries. This study investigated the enhancement of mechanical properties and antibiotic release in ultra-high molecular weight polyethylene (UHMWPE) through the encapsulation of submicron gentamicin sulfate (GS) particles, addressing the critical need for improved implant materials in orthopaedic surgery, particularly in managing PJIs.
Methods: The present study involved embedding submicron GS particles into UHMWPE flakes at concentrations of 2% to 10% by weight.
Risk of Lymph Node Metastasis in T2 Colon Cancer: A Nationwide Population-Based Cohort Study.
Ann Surg Oncol
January 2025
Department of Gastroenterology and Hepatology, Isala, Zwolle, The Netherlands.
Background: Similar to T1 colon cancer (CC), risk stratification may guide T2 CC treatment and reduce unnecessary major surgery. In this study, prediction models were developed that could identify T2 CC patients with a lower risk of lymph node metastasis (LNM) for whom (intensive) follow-up after local treatment could be considered.
Methods: A nationwide cohort study was performed involving pT2 CC patients who underwent surgery between 2012 and 2020, using data from the Dutch ColoRectal Audit, which were linked to the Nationwide Pathology Databank.
A Review of Leveraging Artificial Intelligence to Predict Persistent Postoperative Opioid Use and Opioid Use Disorder and its Ethical Considerations.
Curr Pain Headache Rep
January 2025
Division of Perioperative Informatics, Department of Anesthesiology, University of California, San Diego, La Jolla, CA, USA.
Purpose Of Review: Artificial intelligence (AI) offers a new frontier for aiding in the management of both acute and chronic pain, which may potentially transform opioid prescribing practices and addiction prevention strategies. In this review paper, not only do we discuss some of the current literature around predicting various opioid-related outcomes, but we also briefly point out the next steps to improve trustworthiness of these AI models prior to real-time use in clinical workflow.
Recent Findings: Machine learning-based predictive models for identifying risk for persistent postoperative opioid use have been reported for spine surgery, knee arthroplasty, hip arthroplasty, arthroscopic joint surgery, outpatient surgery, and mixed surgical populations.
Lateral pelvic lymph node dissection (LPLND) in the treatment of rectal cancer: current practice and evolving approaches in India.
Tech Coloproctol
January 2025
Colorectal Division, Department of Surgical Oncology, Tata Memorial Hospital, Mumbai, India.
Background: The introduction of total mesorectal excision improved locoregional control for rectal adenocarcinoma significantly. Standardisation of the technique of LPLND is lacking in literature.
Methods: We describe the current practices of case selection and technical details of lateral lymph node dissection in rectal cancer.
Improving postsurgical paresis in brain tumor patients by transcranial magnetic stimulation.
J Neurooncol
January 2025
Department of Neurosurgery, School of Medicine, Technical University of Munich, Klinikum rechts der Isar, Munich, Germany.
Background And Objectives: Recently, reduction of transcallosal inhibition by contralateral navigated repetitive transcranial magnetic stimulation (nrTMS) improved neurorehabilitation of glioma patients with new postoperative paresis. This multicentric study examines the effect of postoperative nrTMS in brain tumor patients to treat surgery-related upper extremity paresis.
Methods: This is a secondary analysis of two randomized and three one-arm studies in brain tumor patients with new/progressive postoperative paresis.
