Robot-Assisted Positioning for Percutaneous Endoscopic Interlaminar Discectomy.
Orthop Surg
January 2025
Orthopaedic Department, Peking University Third Hospital, Beijing, China.
Objective: During percutaneous endoscopic interlaminar discectomy (PEID), a range of technologies including medical robotics, visual navigation, and spatial registration have been proposed to expand the application scope and success rate of minimally invasive surgery. The use of robotic technology in surgery is conducive to improving accuracy and reducing risk. This study aims to introduce a precise and efficient targeting method tailored for robot-assisted positioning under C-arm fluoroscopy inPEID.

Vertical jump height from a countermovement jump is a widespread metric to assess the lower limb functionality. Motion capture systems and force platforms are considered gold standards to estimate vertical jump height; however, their use in ecological settings is limited. This study aimed to evaluate the feasibility of low-sampling-rate inertial measurement units as an alternative to the gold standard systems.

: The assessment of left ventricular (LV) filling pressure in heart failure (HF) poses a diagnostic challenge, as HF patients may have normal LV filling pressures at rest but often display elevated LV filling pressures during exercise. Rapid preload increase during passive leg lift (PLL) may unmask HF in such challenging scenarios. We explored the dynamic interplay between simultaneous left atrial (LA) function and volume using LA strain/volume loops during rest and PLL and compared its diagnostic performance with conventional echocardiographic surrogates to detect elevated LV filling pressure.

Silver chalcogenides exhibit exceptional transport properties but face structural instability at high temperatures, limiting their practical applications. Using AgTe as a model, it is confirm that silver whisker growth above the phase transition renders AgTe unsuitable for thermoelectric applications. Here, the whisker growth mechanism is investigated and propose an inhibition strategy, overcoming a major obstacle in using silver chalcogenides.

However, it is associated with a higher risk of venous thrombosis, which can jeopardize the survival of the pancreaticoduodenal graft. This case report describes a patient with type 2 diabetes, hypertension, and ESRD who developed acute, occlusive deep vein thrombosis (DVT) involving the right common femoral, profunda femoral, and greater saphenous veins on postoperative day 1 (POD1) following a deceased donor SPK transplant, despite systemic prophylactic anticoagulation.
