This study highlights the vital role of high-resolution (HR), open-source land cover maps for food security, land use planning, and environmental protection. The scarcity of freely available HR datasets underscores the importance of multi-spectral HR aerial images. We used unmanned aerial vehicle (UAV) to capture images for a centimeter-level orthomosaics, facilitating advanced remote sensing and spatial analysis.

Methods: We used a longitudinal sample of 1,103 seventh-grade students from 15 Brazilian public schools. We explored if attitudes toward drug use, decision-making, communication, and alcohol resistance skills at baseline predicted alcohol outcomes nine months later.

Background: In SARS-CoV-2 infection, cytokines and laboratory biomarkers play a key role in disease progression and their long-term levels have been associated with the outcome of long COVID-19.
Objectives: I) study the levels of cytokines, hematological and biochemical biomarkers in the acute and post-acute phases of COVID-19 disease; and II) assess the impact of COVID-19 vaccine doses on fatigue symptoms.
Methods: This study is an exploratory cohort nested within a clinical and laboratory follow-up of surviving participants after pre-vaccine acute COVID-19 infection with severe clinical manifestations.
Background: The widely implemented prevention program in Brazil, PROERD (a translated version of the DARE-kiR program), showed no evidence of effect in preventing drug use in a recent trial. The lack of cultural adaptation and instructors' deviations from the curriculum were identified as potential reasons for its ineffectiveness. This study aims to identify points of inadequacy of the PROERD program for the Brazilian culture, suggesting strategies for revising the curriculum to improve implementation.

Our aim was to compare respiratory sounds recorded by a smartphone and a digital stethoscope by assessing the proportion of quality recordings and adventitious sounds detected by each device.
Methods: A comparative early feasibility study with children from a public school in Northern Portugal was conducted.
