A worldwide assessment of the mechanical ventilation in patients with acute exacerbations of chronic obstructive pulmonary disease. Analysis of the VENTILAGROUP over time. A retrospective, multicenter study.

Background: The trend over time and across different geographical areas of outcomes and management with noninvasive ventilation or invasive mechanical ventilation in patients admitted for acute exacerbations of chronic obstructive pulmonary disease and treated with ventilatory support is unknown. The purpose of this study was to describe outcomes and identify variables associated with survival for patients admitted to an intensive care unit (ICU) with acute exacerbation of chronic obstructive pulmonary disease [aeCOPD] who received noninvasive or invasive mechanical ventilation worldwide.

Methods: Retrospective, multi-national, and multicenter studies, including four observational cohort studies, were carried out in 1998, 2004, 2010, and 2016 for the VENTILAGROUP following the same methodology.

[Cardiovascular risk factors of medical specialists in Argentina].

Introduction: The objective was to analyze the prevalence of classic CVRFs in specialist doctors and establish if there are differences by sex, age and specialty.

Materials And Methods: Observational, cross-sectional study carried out through an anonymous selfadministered survey of specialist doctors throughout the country. Sociodemographic and CVRF data were collected by self-report.

Integrated surveillance for Oropouche Virus: Molecular evidence of potential urban vectors during an outbreak in the Brazilian Amazon.

The Oropouche Virus (OROV) has Culicoides paraensis as its main vector in the urban cycle. Diagnoses of acute febrile cases and entomological collections were performed between January and April 2024 in the urban setting of Porto Velho, a city located in the western Brazilian Amazon. A total of 904 human samples were evaluated using RT-qPCR, of which 328 were positive for OROV.

Joint aerobic biodegradation of synthetic and natural textile microfibers and laundry surfactants.

Microfibers (MFs) represent one of the most prominent sources of microplastics in aquatic environments, primarily released during textile washing alongside surfactants found in laundry detergents. This study aimed to investigate the biodegradability of natural (cotton) and synthetic (polyester) MFs individually and in combination with two surfactants: sodium lauryl sulfate (SLS, anionic) and polyoxyethylene glycerol ester (PGE-OE6, nonionic). Using the OECD 301 F test, the research assessed biodegradation patterns and environmental interactions.

Effect of BMI on Caries Assessed by Structural Equation Modelling in an Adult Brazilian Population.

Objectives: Compare different behavioural, environmental and socioeconomic factors for caries with transversal data to decompose the direct and indirect effects of body mass index (BMI) in relation to coronal and root caries.

Methods: This cross-sectional study used a representative sample of 1002 individuals aged ≥ 35 years living in Porto Alegre. Questionnaires recorded age, sex, educational level, tooth brushing frequency and access to dental services.
