Introduction: Commercial off-the-shelf (COTS) intravenous fluid (IVF) containers contain residual air, introducing the risk of venous air embolism (VAE). Venous air embolism occurs when air displaces blood flow in vasculature. The danger from residual air is often negligible in terrestrial settings, where gravitational forces generate buoyancy, pushing residual air to the top of the IVF container.

Our study evaluates the effectiveness of emergency vaccination using a dynamic disease transmission model for a potential large-scale outbreak in Rome, Italy.
Methods: The model incorporates a susceptible-exposed-infected-recovered (SEIR) framework for human and mosquito populations, taking into account temperature-dependent mosquito lifecycle dynamics, human-mosquito interactions, and various vaccination scenarios.
Modified atmosphere packaging (MAP) is widely used to preserve fresh fruits. In the case of exporting products in bulk formats (2-5 kg), perforated MAP can help extend shelf life if appropriately configured to reach suitable gas levels. This study evaluated the configuration of a perforated MAP system for purple passion (Passiflora edulis Sims) fruits based on modeling and simulation of changes in gas levels within the package headspace and experimental data on the respiration and transpiration of the fruits.
