AI Article Synopsis
Article Abstract
Actomyosin rings are transient organelles that execute cytokinesis, morphogenesis, and wound healing. In this issue of Developmental Cell, Burkel et al. (2012) call into question the assumption that such rings close via sliding filament contractility and elegantly reveal flux of Rho family GTPases within these dynamic structures.

Efficacy of wound care ointment in healing infectious wounds after anorectal surgery: A randomized controlled trial.
Medicine (Baltimore)
January 2025
Anorectal Department, People's Hospital of Leshan, Leshan, Sichuan, China.
Background: This study evaluates the efficacy of a novel bismuth subgallate-borneol compound ointment as an adjuvant therapy in promoting postoperative healing of infectious incisions after anorectal surgery.
Methods: From June 2023 to October 2023, 46 patients with perianal abscess and anal fistula treated at our institution's Anorectal Surgery Department were enrolled in this prospective randomized controlled study. Patients were randomly allocated into 2 groups: the experimental group (n = 23) received conventional wound care plus a proprietary ointment containing 4.
Construction of a prognostic signature based on T-helper 17 cells differentiation-related genes for predicting survival and tumor microenvironment in head and neck squamous cell carcinoma.
Medicine (Baltimore)
January 2025
Department of Otolaryngology, Hangzhou Red Cross Hospital (Zhejiang Hospital of Integrated Traditional Chinese and Western Medicine), Hangzhou, Zhejiang, China.
T-helper 17 (Th17) cells significantly influence the onset and advancement of malignancies. This study endeavor focused on delineating molecular classifications and developing a prognostic signature grounded in Th17 cell differentiation-related genes (TCDRGs) using machine learning algorithms in head and neck squamous cell carcinoma (HNSCC). A consensus clustering approach was applied to The Cancer Genome Atlas-HNSCC cohort based on TCDRGs, followed by an examination of differential gene expression using the limma package.

PLoS One
January 2025
Department of Anorectal Surgery, Shuguang Hospital, Shanghai University of Traditional Chinese Medicine, Shanghai, China.
Background: Anal fistula surgery often leads to postoperative pain, which can hinder recovery and negatively impact patients' quality of life. This prospective, randomised, controlled trial (RCT) aims to investigate the efficacy of acupuncture in alleviating postoperative pain and reducing the usage of analgesic medications following anal fistula surgery.
Methods: This single-centre, patient-blinded, assessor-blinded, placebo-controlled randomised controlled trial (RCT) will be conducted at a tertiary referral hospital.
A systematic in vitro study of the effect of normoglycaemic and hyperglycaemic conditions on the biochemical and cellular interactions of clinically-available wound dressings with different physicochemical properties.
PLoS One
January 2025
Centre for Regenerative Medicine and Devices, University of Brighton, Brighton, United Kingdom.
Diabetic foot, leg ulcers and decubitus ulcers affect millions of individuals worldwide leading to poor quality of life, pain and in several cases to limb amputations. Despite the global dimension of this clinical problem, limited progress has been made in developing more efficacious wound dressings, the design of which currently focusses on wound protection and control of its exudate volume. The present in vitro study systematically analysed seven types of clinically-available wound dressings made of different biomaterial composition and engineering.

JBJS Case Connect
January 2025
Department of Orthopaedics, Mass General Brigham, Boston, Massachusetts.
Case: A 51-year-old male polytrauma patient presented with bilateral calcaneus fractures after a fall. This report describes treatment of his right comminuted Sanders IV calcaneus fracture with percutaneous open reduction internal fixation (ORIF) and minimally invasive surgery (MIS) primary subtalar fusion to restore alignment and preserve soft tissue.
Conclusion: Unlike traditional open approaches, which are prone to wound complications due to larger incisions, our approach of maintaining fracture alignment during joint preparation using an MIS burr for acute posttrauma subtalar arthrodesis and percutaneous ORIF appears to have reduced these risks, resulting in successful radiological healing and functional recovery at 1-year follow-up.
