Catastrophic health expenditures incurred by families in 2003, 2009 and 2018 in the Federal District, Brazil: evolution and composition.

Objective: To investigate the evolution of prevalence of catastrophic health expenditure in the Brazilian Federal District at three different times (2003, 2009 and 2018), as well, to identify the composition of outof- pocket expenditure in the respective years.

Method: Time series study, using descriptive data from the Family Budget Survey. Prevalence was stratified by consumption quintiles.

RGB sensor integrated into unmanned aerial vehicle for monitoring cyanobacterial density in reservoirs.

The proliferation of cyanobacteria has become a significant water management challenge due to the increasing eutrophication of water supply reservoirs. Cyanobacterial blooms thrive on elevated nutrient concentrations and form extensive green mats, disrupting the local ecosystem. Furthermore, many cyanobacterial species can produce toxins that are lethal to vertebrates called cyanotoxins.

Expression of Plasma Levels of miRNA-181b and miRNA-21 in Patients With Abdominal Aortic Aneurysms and Their Effect on Clinical Outcome After Endovascular Treatment.

Introduction: Abdominal aortic aneurysms (AAA) are major causes of morbidity and mortality in the elderly population. Endovascular aneurysm repair (EVAR) is associated with lower complications rates than conventional treatment; however, rigorous follow-up with contrast imaging is required to confirm aneurysmal sac exclusion. The main objective of this study was to quantify and evaluate miRNA expression response to EVAR based on serum dosages at the 6-month follow-up.

Aqueous extracts of and as promising sources of antibiofilm compounds against mucoid and small colony variants of and .

Bacterial biofilms formed by and pose significant challenges in treating cystic fibrosis (CF) airway infections due to their resistance to antibiotics. New therapeutic approaches are urgently needed to treat these chronic infections. This study aimed to investigate the antibiofilm potential of various plant extracts, specifically targeting mucoid and small colony variants of and and strains.

Prevalence of SARS-CoV-2 infections and socio-occupational profile of delivery riders during the COVID-19 pandemic.

Introduction: We assessed the prevalence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and associated socio-occupational factors among delivery riders from a Brazilian city at two time points during the pandemic.

Methodology: Surveys for antibody and viral RNA testing were conducted from November 2020 to January 2021, and from March to May 2021 in a group of 117 delivery riders. A questionnaire on socio-occupational characteristics and coronavirus disease 2019 (COVID-19) preventive measures was completed.
