Solar-based technologies for removing potentially toxic metals from water sources: a review.

Technological advances have led to a proportional increase in the deposition of contaminants across various environmental compartments, including water sources. Heavy metals, also known as potentially toxic metals, are of particular concern due to their significant harmful impacts on environmental and human health. Among the available methods for mitigating the threat of these metals in water, solar radiation-based technologies stand out for their cleanliness, cost-effectiveness, and efficiency in removing or reducing the toxicity of heavy metals.

Bullying in adolescents across three years in the context of the COVID-19 pandemic: a repeated cross-sectional and prospective analysis.

Background: Bullying has been identified as a risk factor for many issues among adolescents. Although it was already considered a public health issue in Brazil before the COVID-19 pandemic, little is known about how the pandemic and associated public health measures have affected bullying behavior.

Objective: To explore changes in bullying victimization and perpetration among Brazilian high school students from 2019 to 2022.

Effects of instructional therapeutic play in the behavior of children during the first attempt at intravenous catheterization.

Objective: To verify the effects of instructional therapeutic play on the behavior of children during the first attempt at peripheral intravenous catheterization.

Method: This is a quasi-experimental post hoc analysis with a non-equivalent control group, secondary to a randomized clinical trial. The convenience sample comprised 193 children, allocated for convenience into an intervention group (preparation for catheterization with a therapeutic play; n=101 children) and a control group (preparation with structured conversation supported by the use of a booklet; n=92 children).

Spatial, temporal, and space-time analysis of leptospirosis cases in Acre, 2001-2022.

Objective: To identify clusters of high and low risk for the occurrence of leptospirosis in space and space-time in Acre, between 2001 and 2022, as well as to characterize temporal trends and epidemiological profiles of the disease in the state.

Methods: An ecological study of cases mandatorily reported by health services in Brazil. For the analysis of clusters in space and space-time, the SaTScan software was used, which calculated the relative risks (RR).
