Healthcare Provider's Preferences on Open Versus Restricted Visiting Hours in Surgical Intensive Care Unit.

Background: The increasing consideration of open visiting hours in intensive care units (ICUs) has presented implementation challenges. Recognizing the invaluable insights of healthcare providers, this study aimed to assess their perspectives on the potential impact of altering ICU visiting policies on patient care.

Materials And Methods:  In a single-institution, cross-sectional study, a five-point Likert survey was administered to healthcare providers working in a surgical ICU to assess their perceptions of open and restricted visiting hours.

Impacts of cattle management and agricultural practices on water quality through different approaches: physicochemical and ecotoxicological parameters.

The intensification of livestock farming can pose risks to the environment due to the increased use of veterinary products and the generation of waste in confined areas. The quality of water bodies near livestock establishments (Areco River (A) and Doblado stream (D), San Antonio de Areco, Buenos Aires, Argentina) was studied by physicochemical parameters, metals, pesticides, emerging contaminants, and lethal and sublethal toxicity (neurotoxicity and oxidative stress) in larvae of the native amphibian Rhinella arenarum. Six sites were selected: upstream (S1A and S1D), at the level (S2A and S2D), and downstream (S3A and S3D) from the establishments.

Assessing the transformation products and fate of Oxytetracycline by simulated aerobic degradation tests.

Oxytetracycline (OTC) is a widely used broad-spectrum antibiotic, whose presence in water and sediments was reported in various regions of the world. The effects of OTC and other tetracyclines on the environment have been intensively studied although many of their transformation products (TPs) formed in the environment and their impact have not been yet fully characterized. Abiotic and biotic degradation tests under aerobic conditions at two pH values were carried out using OTC in artificial water/sediment systems to assess the effect of these variables on the environmental fate of the pollutant.

Metals, pesticides, and emerging contaminants on water bodies from agricultural areas and the effects on a native amphibian.

In the Paraná River lower basin, an important agro-productive area of Argentina, crop fields and cattle breeding activities are common and may affect water quality. So, the aim of this study was to analyze the impacts of cattle breeding and agricultural activities on a stream from Buenos Aires, through physicochemical parameters (metals, pesticides, and emerging contaminants) and ecotoxicological parameters with Rhinella arenarum larvae, a native amphibian species. Three sites were selected on an ordinary plain stream that goes through agricultural fields and a cattle breeding establishment (upstream -S1-, near -S2- and downstream -S3- the establishment).
