The impact of vaccination on the length of stay of hospitalized COVID-19 patients in Brazil.

Background: The length of hospital stays for severe COVID-19 cases significantly impacts the overall burden on the health system. Current COVID-19 vaccines have proven effective at reducing severe cases. However, the influence of vaccination status on the progression of COVID-19 after hospitalization is not well understood.

Effect of Sand Addition on Laterite Soil Stabilization.

Lateritic soils, particularly abundant in tropical regions, have been successfully used in the construction of unbound layers of flexible pavements in Brazil since the 1970s. Despite their potential, these soils are often discarded or only recommended after stabilization processes, based on traditional parameters such as gradation requirements and Atterberg limits. This study investigates the mechanical characteristics of a lateritic soil from Roraima, focusing on its resilient modulus and permanent deformation properties, assessed through repeated load triaxial tests.

Mucosal-adapted bacteriophages as a preventive strategy for a lethal Pseudomonas aeruginosa challenge in mice.

Pseudomonas aeruginosa is an emergent threat due to the antimicrobial resistance crisis. Bacteriophages (phages) are promising agents for phage therapy approaches against P. aeruginosa.

Association of Current and Long-Term Estradiol Use with Carotid Intima Media Thickness Among Transgender Women: A Cross-Sectional Study.

Purpose: Epidemiologic studies suggest that the transgender population has a higher burden of cardiovascular (CV) disease. We aimed to assess CV risk and investigate the relationship between estradiol (E2) or ethinylestradiol (EE) use and carotid intima media thickness (cIMT) in transgender women.

Methods: This is a cross-sectional analysis nested into a transgender-specific cohort in Rio de Janeiro, Brazil, from August 2015 to February 2018.

Chemical characterization, assessment of acute oral toxicity, and antinociceptive potential of the methanolic extract of (Arruda) Schott leaves from Brazil.

Background: (Arruda) Schott is popularly known as "aninga," "aningaçu," "aningaíba," and "aninga-do-igapó." Compresses and plasters made from the leaves of this medicinal plant are used to treat abscesses, tumors, and pain caused by stingray stings.

Aim Of The Study: This study aimed to chemically characterize the methanolic extract of leaves (MEMLL), as well as to verify their acute oral toxicity and antinociceptive potential.
