Knowledge and behavior towards COVID-19 in the northern region of the state of Rio de Janeiro - Brazil.

Introduction: Despite efforts by health organizations to share evidence-based information, fake news hindered the promotion of social distancing and vaccination during the coronavirus disease 2019 (COVID-19) pandemic. This study analyzed COVID-19 knowledge and practices in a vulnerable area in northern Rio de Janeiro, acknowledging the influence of the complex social and economic landscape on public health perceptions.

Methodology: This cross-sectional study was conducted in Novo Eldorado - a low-income, conflict-affected neighborhood in Campos dos Goytacazes - using a structured questionnaire, following the peak of COVID-19 deaths in Brazil (July-December 2021).

Air Passengers' Risk of SARS-CoV-2 Infection with a 14-day Quarantine and Accuracy Assessment of a Symptom-based Screening System at an Airport.

Objectives: This study aimed to validate the risk of SARS-CoV-2 infection, identify infection risk factors among air passengers subject to a 14-day mandatory quarantine, and evaluate the accuracy of mass symptom-based screening criteria at an airport.

Methods: This retrospective cohort study analyzed data from 116,004 air passengers who entered Thailand through Suvarnabhumi Airport in Bangkok from April to September 2020. The incidence of SARS-CoV-2 infection, risk characteristics, and accuracy indices of symptom-based screening were calculated.

Photodynamic therapy reduces viability, enhances itraconazole activity, and impairs mitochondrial physiology of Sporothrix brasiliensis.

Sporothrix brasiliensis is the main agent of sporotrichosis in Brazil, with few therapeutic options. This study aimed to investigate the in vitro efficacy of photodynamic therapy using a diode laser (InGaAIP) in combination with the photosensitizer methylene blue against S. brasiliensis yeasts.

The biofilm produced by Cryptococcus neoformans protects the fungus from the antifungal and anti-melanin effects of cyclosporine.

Understanding Cryptococcus neoformans pathogenesis requires a detailed analysis of the various virulence factors that contribute to its ability to cause disease. Cyclosporine, calcineurin inhibitor, impairs C. neoformans production of a polysaccharide capsule and secretion of urease, which are critical for cryptococcal pathogenesis.
