Vection is enhanced by visual oscillation based on four-stroke apparent motion.

Illusions of self-motion (vection) can be improved by adding global visual oscillation to patterns of optic flow. Here we examined whether adding apparent visual oscillation (based on four-stroke apparent motion-4SAM) also improves vection. This apparent vertical oscillation was added to self-motion displays simulating constant velocity leftward self-motion.

Implementing recycling in the operating room: a single-center experience.

Background: Climate change poses significant challenges to global health, exacerbated by healthcare systems' carbon footprint and waste generation. Surgical activities contribute to these impacts, necessitating sustainable practices to mitigate environmental harm. This study aims to assess the feasibility and effectiveness of a recycling program in reducing waste, carbon emissions, and disposal costs in the operating rooms (ORs).

Advanced Non-linear Modeling and Explainable Artificial Intelligence Techniques for Predicting 30-Day Complications in Bariatric Surgery: A Single-Center Study.

Purpose: Metabolic bariatric surgery (MBS) became integral to managing severe obesity. Understanding surgical risks associated with MBS is crucial. Different scores, such as the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP), aid in patient selection and outcome prediction.

Lung Volume and Ventilation Distribution After Bariatric Surgery: High-Flow Nasal Cannula Versus CPAP.

Background: Patients with obesity are at increased risk of postoperative pulmonary complications. CPAP has been used successfully to prevent and treat acute respiratory failure, but in many clinical scenarios, high-flow nasal cannula (HFNC) therapy is emerging as a possible alternative. We aimed to compare HFNC and CPAP in a sequential study measuring their effects on gas exchange, lung volumes, and gas distribution within the lungs measured through electrical impedance tomography (EIT).
