The nursing practice environment and hospital sociotechnical complexity: a mixed-methods study.

Objectives: to analyze the relationship between the nursing practice environment and hospital sociotechnical complexity as perceived by nurses.

Methods: a sequential explanatory mixed-methods study was conducted in a hospital in southern Brazil. The Brazilian version of the Practice Environment Scale-Nursing Work Index and the Complexity Characterization Questionnaire were administered to 132 nurses.

Implementation of bedside medication preparation in intensive care: post-improvement cycle.

Objective: To assess the implementation of the bedside medication preparation process in an Intensive Care Unit, following a quality improvement cycle.

Method: A quasi-experimental study with non-paired samples, pre- and post-implementation, conducted in an Intensive Care Unit of a public hospital in southern Brazil, from September 2022 to April 2023, following the guidelines of the Standards for Quality Improvement Reporting Excellence 2.0.

Moderate and severe adverse events in pediatrics: characteristics of incidents reported during the COVID-19 pandemic.

Objective: To verify the characteristics of safety incident reports resulting in moderate and severe harm to pediatric patients in two hospitals during the COVID-19 pandemic.

Method: Cross-sectional study conducted in two hospitals in southern Brazil. The sample consisted of 137 notifications from March 2020 to August 2021.

Pre- and postsynaptic nanostructures increase in size and complexity after induction of long-term potentiation.

Synapses, specialized contact sites between neurons, are the fundamental elements of neuronal information transfer. Synaptic plasticity involves changes in synaptic morphology and the number of neurotransmitter receptors, and is thought to underlie learning and memory. However, it is not clear how these structural and functional changes are connected.

Testing of Different Digestion Solutions on Tissue Samples and the Effects of Used Potassium Hydroxide Solution on Polystyrene Microspheres.

Microplastic particles are ubiquitous in our environment, having entered the air, the water, the soil, and ultimately our food chain. Owing to their small size, these particles can potentially enter the bloodstream and accumulate in the organs. To detect microplastics using existing methods, they must first be isolated.
