Preschool teachers’ ideas about practices to promote peer relations: Using Q methodology to determine viewpoints

An internationally accepted definition of early childhood inclusion includes the right to achieve a sense of belonging and membership, positive social relationships, and friendships. Although Portuguese preschool curriculum guidelines value childchild interactions as an outcome by itself and as means to achieving other development and learning outcomes it does not explicitly mention social participation indicators. Additionally, information is lacking on Portuguese preschool teachers’ beliefs, priorities, and practices specifically related to the support of peer relations. This study was developed in the scope of the project Enhancing peer relationships: Preschool teachers' ideas and practices. One of its goals is to understand Portuguese preschool teacher’s ideas about what is important in supporting peer interactions, relationships, and group membership, for children with and without disabilities. To pursue this goal Q methodology was applied. We developed a Q sample consisting of 74 items that reflect a range of possible interventions targeted at enhancing social inclusion and peer interactions and relationships. The P sample was composed by 43 preschool teachers and their individual Q sorts were subjected to principal components analyses (PCA) followed by varimax rotation. A seven-component solution, explaining 55.5% of the variance, was considered the starting point for the decision-making process on the number of components to be considered as the best solution. Both statistical and conceptual criteria are being used to determine the final number of viewpoints. This presentation describes this decision-making process and the results will be discussed according to their implications for the global project.info:eu-repo/semantics/publishedVersio

An exploratory study for the implementation of the oxidative potential assessment of particulate matter in Portugal

Particulate matter (PM) is a harmful air pollutant that damages human health by inducing oxidative stress through the excessive generation of reactive oxygen species (ROS). Oxidative Potential (OP) is a proposed metric to measure PM's capacity to generate ROS (Almetwally et al., 2020; Jiang et al., 2019). This study aims to implement the OPDTT assessment methodology at C2TN (Portugal). A set of PM2.5 samples was evaluated using a widely used protocol (Chirizzi et al., 2017), and the results were compared to the values previously obtained at DISTEBA, where the protocol is well established. Moreover, the use of the reference material SRM 1648 (Urban Particulate) as a standard for determining OPDTT was also evaluated. Analyzing a 10 mg.L-1 solution of the reference material, it was possible to conclude that the standard solution presented an average DTT activity (normalized to the mass) value of 27.60 ± 3.79 pmol.min-1.μg-1.info:eu-repo/semantics/publishedVersio

Positive Fluid Balance Was Associated with Mortality in Patients with Acute-on-Chronic Liver Failure: a Cohort Study

Purpose: We aimed to study the effect of FB in the outcomes of critically-ill patients with cirrhosis. Materials: Retrospective analysis of all adult consecutive admissions of patients with cirrhosis and organ failures to the Intensive Care Unit (ICU) at Curry Cabral Hospital (Lisbon, Portugal) and University of Alberta Hospital (Edmonton, Canada) on 08/2013-08/2017. Primary exposure was FB at 3 and 7 days post ICU admission. Primary endpoint was hospital mortality. Results: Amongst 333 patients, median age was 56 years and 67.6% were men. Median MELD, APACHEII, CLIF-SOFA, and CLIF-C-ACLF scores on ICU admission were 27, 28, 14, and 54, respectively. ICU and hospital mortality rates were 33.0% and 49.2%, respectively. While median FB at 3 days post ICU admission (+5.46 l vs. +6.62 l; P = 0.74) was not associated with hospital mortality, higher median FB at 7 days post ICU admission (+13.50 l vs. +6.90 l; P = 0.036) was associated with higher hospital mortality. This association remained significant (OR 95%CI = 1.04 [1.01;1.07] per each l) after adjustment for confounders (age, ascites, infection, lactate, and number of organ failures). Conclusions: FB may be a therapeutic target that helps to improve the outcomes of patients with acute-on-chronic liver failure. This data may inform future clinical trials.info:eu-repo/semantics/publishedVersio
