The Automatic External Cardioverter-Defibrillator

In-hospital cardiac arrest remains a major problem but new technologies allowing fully automatic external defibrillation are available. These technologies allow the concept of “external therapeutic monitoring” of lethal arrhythmias. Since early defibrillation improves outcome by decreasing morbidity and mortality, the use of this device should improve the outcome of in-hospital cardiac arrest victims. Furthermore, the use of these devices could allow safe monitoring and treatment of patients at risk of cardiac arrest who not necessarily must be in conventional monitoring units (Intensive or Coronary Care Units) saving costs with a more meaningful use of resources. The capability to provide early defibrillation within any patient-care areas should be considered as an obligation (“standard of care”) of the modern hospital

Physiological Benefits of Dietary Lysophospholipid Supplementation in a Marine Fish Model: Deep Analyses of Modes of Action

Given the hydrophilic structure of lysophospholipids (LPLs), their dietary inclusion translates into a better emulsifying capacity of the dietary components. The present study aimed to understand the mechanisms underlying the growth-promoting effect of LPL supplementation by undertaking deep analyses of the proximal intestine and liver interactomes. The Atlantic salmon (Salmo salar) was selected as the main aquaculture species model. The animals were divided into two groups: one was fed a control diet (C-diet) and the other a feed (LPL-diet) supplemented with an LPL-based digestive enhancer (0.1% AQUALYSO®, Adisseo). The LPL-diet had a positive effect on the fish by increasing the final weight by 5% and reducing total serum lipids, mainly due to a decrease in the plasma phospholipid (p < 0.05). In the intestine, the upregulated interactome suggests a more robust digestive capacity, improving vesicle-trafficking-related proteins, complex sugar hydrolysis, and lipid metabolism. In the liver, the LPL-diet promotes better nutrients, increasing several metabolic pathways. The downregulation of the responses to stress and stimuli could be related to a reduced proinflammatory state. This study on the benefits and modes of action of dietary LPLs opens a new window into fish nutrition and could be extended to other productive species.info:eu-repo/semantics/publishedVersio

Coronavirus Disease 2019 and Cardiac Arrhythmias

The emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a very contagious virus, has led to the coronavirus disease 2019 (COVID-19) pandemic. The clinical manifestations of this virus in humans vary widely, from asymptomatic to severe, with diverse symptomatology and even death. The substantial transmission from asymptomatic people has facilitated the widespread transmission of SARS-CoV-2, hampering public health initiatives to identify and isolate infected people during the pre-symptomatic contagious period. COVID-19 is associated with cardiac complications that can progress from mild to life-threatening. The aim of this article is to analyse the present knowledge of COVID-19 and cardiac involvement, the development of arrhythmia risk and its treatment

La Cova de l'Avi (Vallirana, Barcelona) y el inicio del Neolítico final en el Nordeste de la Península Ibérica. Inhumaciones colectivas y nuevas redes de intercambio

[spa] Entre el Neolítico medio y el Neolítico final en el Nordeste de la Península Ibérica se producen cambios destacados en las pautas funerarias y en la cultura material de los grupos humanos, especialmente en los ajuares y lugares de enterramiento. Durante el Neolítico medio-reciente son típicas las inhumaciones primarias individuales en fosas con ajuares de cuentas de variscita, sílex melado, vasos cerámicos y puntualmente obsidiana. Por el contrario, durante el Neolítico final se generalizan las inhumaciones colectivas y sucesivas en cuevas y abrigos con ajuares que se caracterizan por la gran disminución de la variscita, sustituida por una gran variedad de colgantes y cuentas en piedra, concha y hueso. Ahora también aparecen las grandes láminas y los puñales de sílex, en ocasiones de procedencia extrapeninsular. La Cova de l'Avi representa en la actualidad el yacimiento cronológicamente más antiguo (c. 4700 BP) en el que se documentan estos nuevos comportamientos funerarios. [eng]The Middle to Late Neolithic transition in NE of Iberian Peninsula is characterized by changes on the mortuary behaviour and archaeological artifacts recorded in the luxury items in grave goods and inhumations cemeteries. Single or double primary burials associated with grave goods of variscite beads, honey flint and obsidian blades during Late Middle Neolithic are replaced for collective inhumations in cave and rock-shelters with grave goods composed mainly by shell, bone and stone beads and pendants, large flint blades and flint daggers coming outside de Iberian Peninsula. Cova de l'Avi represents the earlier site (c. 4700 BP) where these cultural changes and mortuary practices have been documented in NE of Iberi

Compartir ideas, la universidad va al instituto. Análisis de la primera edición de un proyecto de aprendizaje servicio transversal a la Universidad de Barcelona

Esta comunicación presenta las principales claves de análisis y evaluación de la 1a edición del proyecto Compartir Ideas. La Universidad va al instituto. Este es un proyecto de aprendizaje servicio transversal que consiste en un ciclo de conferencias-taller impartidas por estudiantes de la UB sobre temes de interés general relacionados con sus estudios. El objetivo es compartir conocimientos y conversar sobre un tema que la universidad trabaja y que será relevante para la formación del alumnado de secundaria.El proyecto cuenta con el apoyo del Vicerectorado de Política Docente y Lingüística de la Universitat de Barcelona

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
