Language biases and implicit attitudes among university students in Galicia (Spain)
This study aims to contribute to the ongoing debate on the role of language attitudes in Galicia (Spain). By means of a mixed methodological approach, we investigate the interrelation between 168 university students’ Implicit Association Test (IAT) results towards Galician Spanish (GS) and Traditional Galician (TG), and their sociolinguistic
background. The study found complex interrelations of various factors. Family language and everyday language appeared to play a prominent role in determining the implicit language attitudes towards both languages. Proficiency in Galician was the only other factor that significantly contributed to the development of positive
attitudes towards TG, while having Spanish as the L-1 was identified asa key factor in the formation of positive attitudes towards GS. Unlike previous research on explicit attitudes, place of living (rural vs urban) is not associated with (implicit) language attitude formation. Notably, political orientation arises as a relevant factor that should be addressed in future research

Ocean Circulation over Formigas and Ormonde Seamounts
Seamounts constitute an obstacle to the free ocean flow, modifying the patter of circulation. As a result of these alterations, a variety of hydrodynamical processes and phenomena may take place in seamounts, among others, Taylor columns/caps. These oceanographic effects may turn seamounts into very productive ecosystems with high biodiversity. Under these conditions seamounts provide a particularly good environment for the settle of some organisms, acting as stepping stones and contributing to its dispersal. In this study, we verify if these oceanographic effects explain the presence of cold-water corals of Mediterranean origin in the Atlantic. To achieve this, three seamounts in the path of the Mediterranean Outflow Water (MOW) through the Eastern North Atlantic were selected: the Gazul mud volcano, and the Ormonde and Formigas seamounts. In order to determine the hydrographic and dynamical conditions in each one of the three locations, CTD, LADPC and biochemical observations were carried out. Taylor columns were not observed in any of the three sampled areas. Although we found suggestions of upwelling/downwelling systems, their effect was barely noticed in the circulation pattern. The oceanographic processes in those areas are more influenced by the vertical distribution of water masses, which determine the stability of the water column. Moreover, the high values of the Brunt-Väisälä frequency around the MOW halocline can lead to the formation of internal waves. These perturbations in the water column can enhance the vertical mixing, producing suspension, which, in turn, could affect the vertical distribution of cold-water corals

Ocean circulation pattern over North Atlantic seamounts: Ormonde and Formigas
Seamounts constitute an obstacle to the free ocean flow giving rise to a variety
of hydrodynamical processes and phenomena such as, among others, Taylor columns/caps.
As a consequence of that, seamounts may turn into very productive ecosystems with high
biodiversity, which provide a particularly good environment for the settle of some
organisms, acting as stepping stones and contributing to its dispersal. In this study, we
verify if these oceanographic effects explain the presence of cold-water corals of
Mediterranean origin in the Atlantic. To achieve this, CTD, LADPC and biochemical
measurements were carried out in three seamounts in the path of the Mediterranean
Outflow Water (MOW): the Gazul mud volcano, and the Ormonde and Formigas
seamounts. Taylor columns were not observed in any of the three sampled areas. In fact,
the oceanographic processes in those areas are more influenced by the vertical distribution
of water masses, which determine the stability of the water column. Moreover, the high
values of the Brunt-Väisälä frequency around the MOW halocline can lead to the
formation of internal waves. These perturbations in the water column can enhance the
vertical mixing, producing suspension, which, in turn, could affect the vertical distribution
of cold-water corals
The evolution of the ventilatory ratio is a prognostic factor in mechanically ventilated COVID-19 ARDS patients
Background: Mortality due to COVID-19 is high, especially in patients requiring mechanical ventilation. The purpose of the study is to investigate associations between mortality and variables measured during the first three days of mechanical ventilation in patients with COVID-19 intubated at ICU admission. Methods: Multicenter, observational, cohort study includes consecutive patients with COVID-19 admitted to 44 Spanish ICUs between February 25 and July 31, 2020, who required intubation at ICU admission and mechanical ventilation for more than three days. We collected demographic and clinical data prior to admission; information about clinical evolution at days 1 and 3 of mechanical ventilation; and outcomes. Results: Of the 2,095 patients with COVID-19 admitted to the ICU, 1,118 (53.3%) were intubated at day 1 and remained under mechanical ventilation at day three. From days 1 to 3, PaO2/FiO2 increased from 115.6 [80.0-171.2] to 180.0 [135.4-227.9] mmHg and the ventilatory ratio from 1.73 [1.33-2.25] to 1.96 [1.61-2.40]. In-hospital mortality was 38.7%. A higher increase between ICU admission and day 3 in the ventilatory ratio (OR 1.04 [CI 1.01-1.07], p = 0.030) and creatinine levels (OR 1.05 [CI 1.01-1.09], p = 0.005) and a lower increase in platelet counts (OR 0.96 [CI 0.93-1.00], p = 0.037) were independently associated with a higher risk of death. No association between mortality and the PaO2/FiO2 variation was observed (OR 0.99 [CI 0.95 to 1.02], p = 0.47). Conclusions: Higher ventilatory ratio and its increase at day 3 is associated with mortality in patients with COVID-19 receiving mechanical ventilation at ICU admission. No association was found in the PaO2/FiO2 variation
