Studying the Size-Dependence of Graphene Nanoplatelets (GNPs) in the Final Properties of Polyurethane Aerogels: Thermal Insulation and Mechanical Strength.

In the present work, the influence of the addition of graphene nanoplatelets presenting different dimensions on polyurethane-polyisocyanurate aerogel structure and properties has been studied. The obtained aerogels synthesized through a sol-gel method have been fully characterized in terms of density, porosity, specific surface area, mechanical stiffness, thermal conductivity, and speed of sound. Opacified aerogels showing high porosity (>92%) and low densities (78-98 kg/m) have been produced, and the effect of the size and content of graphene nanoplatelets has been studied.

Cost evaluation of acute ischemic stroke in Latin America: a multicentric study.

Background: Current literature highlights a gap in precise stroke cost data for Latin America. This study measures the real costs associated with acute ischemic stroke care in Latin America using Time-Driven Activity-Based Costing (TDABC). The findings aim to lay a solid foundation for adopting value-based healthcare (VBHC) strategies in the region.

Aberrant right subclavian artery: the importance of distinguishing between isolated and non-isolated cases in prenatal diagnosis and clinical management.

Objectives: This study aimed to evaluate the association of aberrant right subclavian artery (ARSA) with genetic abnormalities and postnatal symptomatology, by comparing isolated and non-isolated ARSA cases.

Methods: Retrospective, descriptive and comparative study involving fetuses diagnosed with ARSA during routine fetal ultrasound scans, between 19 and 40 weeks, in a tertiary referral university hospital in Barcelona from January 2007 to December 2023.

Results: Out of 154 fetuses diagnosed with ARSA, 75.

Balance and Health-Related Quality of Life After 1 Year of COVID-19 Social Restriction Measures: A Cross-Sectional Study in Two Samples from Spain.

Background: The COVID-19 pandemic significantly impacted the well-being of the general population. However, more information is needed regarding the relationship between participation-related outcomes. This study aimed to analyze the impact of the pandemic on occupational balance (OB) and health-related quality of life (HRQoL) before and after social restrictions and to explore their relationship with COVID-19 diagnosis.
