Maternal outcomes and risk factors for COVID-19 severity among pregnant women.
Pregnant women may be at higher risk of severe complications associated with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which may lead to obstetrical complications. We performed a case control study comparing pregnant women with severe coronavirus disease 19 (cases) to pregnant women with a milder form (controls) enrolled in the COVI-Preg international registry cohort between March 24 and July 26, 2020. Risk factors for severity, obstetrical and immediate neonatal outcomes were assessed. A total of 926 pregnant women with a positive test for SARS-CoV-2 were included, among which 92 (9.9%) presented with severe COVID-19 disease. Risk factors for severe maternal outcomes were pulmonary comorbidities [aOR 4.3, 95% CI 1.9-9.5], hypertensive disorders [aOR 2.7, 95% CI 1.0-7.0] and diabetes [aOR2.2, 95% CI 1.1-4.5]. Pregnant women with severe maternal outcomes were at higher risk of caesarean section [70.7% (nâ=â53/75)], preterm delivery [62.7% (nâ=â32/51)] and newborns requiring admission to the neonatal intensive care unit [41.3% (nâ=â31/75)]. In this study, several risk factors for developing severe complications of SARS-CoV-2 infection among pregnant women were identified including pulmonary comorbidities, hypertensive disorders and diabetes. Obstetrical and neonatal outcomes appear to be influenced by the severity of maternal disease
The handbook for standardized field and laboratory measurements in terrestrial climate change experiments and observational studies (ClimEx)
1. Climate change is a worldâwide threat to biodiversity and ecosystem structure, functioning and services. To understand the underlying drivers and mechanisms, and to predict the consequences for nature and people, we urgently need better understanding of the direction and magnitude of climate change impacts across the soilâplantâatmosphere continuum. An increasing number of climate change studies are creating new opportunities for meaningful and highâquality generalizations and improved process understanding. However, significant challenges exist related to data availability and/or compatibility across studies, compromising opportunities for data reâuse, synthesis and upscaling. Many of these challenges relate to a lack of an established âbest practiceâ for measuring key impacts and responses. This restrains our current understanding of complex processes and mechanisms in terrestrial ecosystems related to climate change.
2. To overcome these challenges, we collected bestâpractice methods emerging from major ecological research networks and experiments, as synthesized by 115 experts from across a wide range of scientific disciplines. Our handbook contains guidance on the selection of response variables for different purposes, protocols for standardized measurements of 66 such response variables and advice on data management. Specifically, we recommend a minimum subset of variables that should be collected in all climate change studies to allow data reâuse and synthesis, and give guidance on additional variables critical for different types of synthesis and upscaling. The goal of this community effort is to facilitate awareness of the importance and broader application of standardized methods to promote data reâuse, availability, compatibility and transparency. We envision improved research practices that will increase returns on investments in individual research projects, facilitate secondâorder research outputs and create opportunities for collaboration across scientific communities. Ultimately, this should significantly improve the quality and impact of the science, which is required to fulfil society's needs in a changing world
AnĂĄlise da produção cientĂfica dos bibliotecĂĄrios da Universidade Federal do Rio Grande do Sul
Este estudo analisa a produção cientĂfica dos servidores tĂ©cnicos administrativos de nĂvel superior lotados na UFRGS, mais especificamente os servidores que atuam no cargo de bibliotecĂĄrio. Se a perspectiva de galgar novos patamares na vida acadĂȘmica se consolida como uma ação caracterĂstica do habitus do pesquisador, Ă© necessĂĄrio considerar que nas universidades esses outros agentes sociais nĂŁo estĂŁo imunes Ă dinĂąmica mencionada. Cabe considerar as influĂȘncias oriundas das instituiçÔes, pois o sujeito da ciĂȘncia nĂŁo Ă© o cientista singular, mas o campo cientĂfico, como universo das relaçÔes objectivas de comunicação e de concorrĂȘncia. [. . .] Em suma a ciĂȘncia Ă© um imenso aparato de construção colectiva utilizado colectivamente. (Bourdieu, 2008, p. 99)
