A Force-Sensor-Less Approach for Rapid Young's Modulus Identification of Heterogeneous Soft Tissue.
J Biomech Eng
January 2025
State Key Laboratory of Fluid Power and Mechatronic Systems, Department of Mechanical Engineering, Zhejiang University, Hangzhou, 315000, China.
Due to individual differences, accurate identification of tissue elastic parameters is essential for biomechanical modeling in surgical guidance for hepatic venous injections. This paper aims to acquire the absolute Young's modulus of heterogeneous soft tissues during endoscopic surgery with 2D ultrasound images. First, we introduced a force-sensor-less approach that utilizes a pre-calibrated soft patch with a known Young's modulus and its ultrasound images to calculate the external forces exerted by the probe on the tissue.

Indian J Nephrol
July 2024
Department of Medicine, INHS Asvini, Mumbai, India.
Background: External jugular vein (EJV) is used to insert tunneled dialysis catheter (TDC) in patients with no AVF and exhausted right internal jugular veins (IJV). There is scarce data on TDC insertion in EJV by nephrologists with fluoroscopy guidance.
Materials And Methods: This was a prospective observational study that included hemodialysis patients with exhausted right IJV access who underwent EJV TDC insertion, and excluded occluded ipsilateral brachiocephalic vein or superior vena cava, EJV < 5 mm diameter, or patients with existing EJV TDC.
Safe distances for transforaminal posterior lumbar interbody fusion under one-hole split endoscopy: three-dimensional reconstruction measurement of 1-degree degenerative lumbar spondylolisthesis at the L segment.
J Orthop Surg Res
January 2025
Department of Spine Surgery, Binzhou Medical University Hospital, No. 661, Huanghe Er Road, Binzhou, 256603, Shandong, China.
Background: One-hole split endoscopy (OSE) is a novel endoscopic technique that offers some advantages in spinal surgery. However, without a clear understanding of the safe zone for OSE, surgeons risk injuring nerve roots during the procedure. This study aimed to measure the safe distances among critical bone markers, the intervertebral space and nerve roots between 1-degree degenerative lumbar spondylolisthesis (DLS) and non-DLS at the L segment in patients via three-dimensional reconstruction and to compare the differences in relevant safety distances between the two groups.

Lipids Health Dis
January 2025
Department of Endocrinology, The Second Affiliated Hospital of Anhui Medical University, Hefei Anhui, 230601, China.
Background: The triglyceride-glucose (TyG) index has been identified as an alternative biomarker for insulin resistance (IR), while residual cholesterol (RC) is a simple, cost-effective, and easily detectable lipid metabolite. However, the associations of these two markers with carotid plaque presence remain unclear. Thus, this study aimed to explore their associations with carotid plaque presence.

Acta Orthop Belg
December 2024
Percutaneous intra-meniscal platelet-rich plasma (PRP) is a promising tool for managing low-grade meniscal injuries in non-athletic patients. The study evaluates the clinical and radiological outcomes of PRP intra-meniscal injection in meniscal tears. Forty-eight patients were injected with 3 injections of PRP at an interval of one week with a standardised technique under sonographic guidance.
