Background: The fixation of an endotracheal tube must be rapid in conditions involving numerous casualties, such as a chemical warfare (CW) situation. The tube also should be fixed and strong to prevent unplanned extubations.
Methods: We developed a technique for the evaluation of fixation methods. This technique was used to evaluate four methods. Three commercial fixators were compared with the fixation method used today in the Israeli Defense Forces (IDF) and commonly used in different out-of-hospital settings. The exercises were performed on adult intubation mannequins with and without CW protective gear. The fixations were timed, and their quality was evaluated by the participants and inspectors.
Results: The time score for the method used today in the IDF was significantly higher compared with the commercial fixation methods. The quality scores for the Thomas fixator and the IDF method were significantly higher than for the fixators by VBM and Rusch. The CW protective gear significantly prolonged the time but did not affect the quality of the fixation.
Conclusions: With this technique, a good estimation of the time and quality of fixation can be achieved.

Diagnosis of Parkinson's disease by eliciting trait-specific eye movements in multi-visual tasks.

Background: Parkinson's Disease (PD) is a neurodegenerative disorder, and eye movement abnormalities are a significant symptom of its diagnosis. In this paper, we developed a multi-task driven by eye movement in a virtual reality (VR) environment to elicit PD-specific eye movement abnormalities. The abnormal features were subsequently modeled by using the proposed deep learning algorithm to achieve an auxiliary diagnosis of PD.

Objectives: Tuberculosis of the hip joint is a common form of bone tuberculosis that can cause severe joint destruction and affect quality of life. Total hip arthroplasty (THA) is an important way to treat hip joint-related diseases. In recent years, THA has been applied to treat tuberculosis of the hip joint and has achieved certain results.

Background: Increased attention allocation to negative-valenced information and decreased attention allocation to positive-valenced information have been implicated in the etiology and maintenance of depression. The Matrix task, a free-viewing eye-tracking attention assessment task, has shown corroborating results, coupled with adequate reliability. Yet, replication efforts are still needed.

Department of Orthopedics, The First People's Hospital of Longquanyi District, Chengdu, Sichuan, China.
The aim was to study the independent risk factors of internal fixation failure in proximal femoral anti-rotation intramedullary nailing for intertrochanteric femur fracture, and to build a nomogram prediction model accordingly. Clinical data of patients with intertrochanteric femoral rotor fractures admitted to the First People's Hospital of Longquanyi District from January 2018 to January 2023 were retrospectively collected. The occurrence of spiral blade cut out, internal fixation breakage, peri-internal fixation fracture, hip internal rotation deformity, and fracture nonunion within 1 year after surgery were included in the internal fixation failure group, and the rest were included in the internal fixation success group.

Background: Paediatric upper limb fractures are commonly treated with Kirschner (K) wire fixation, which can be buried or left exposed. Although both techniques are widely used, controversy remains regarding infection risk, complications, and other clinical outcomes between buried and exposed K-wires. This systematic review and meta-analysis aimed to compare infection rates and secondary outcomes between buried and exposed K-wires in paediatric upper limb fractures located distal to and including the elbow, and proximal to the carpus.
