Dark Matter Phenomenology: Sterile Neutrino Portal and Gravitational Portal in Extra-Dimensions

2021

El Modelo Estándar de las Interacciones Fundamentales (SM) representa una de las teorías más precisas de la física. Entre las predicciones del SM encontramos, por ejemplo, el momento magnético anómalo del electrón a_e = 0,001159652181643 (764). Esta predicción coincide con los resultados experimentales en más de diez dígitos significativos, la predicción más precisa en la historia de la física. Sin embargo, hoy en día tenemos varias evidencias de que el SM solo explica el 5% del contenido de materia del Universo. El otro 95% está compuesto por las denominadas Energía Oscura y Materia Oscura. Como sugieren sus nombres, la naturaleza de estos dos componentes del contenido de energía / materia…

International trade and migrant networks: Is It really about qualifications?

2014

Personal characteristics of migrants could help to strengthen the impact of migrant networks on bilateral trade. While most of the attention has been focused on immigrants' educational attainment, this paper focuses on the relevance of the tasks carried out by migrants. Our empirical results confirm that the existence of a large number of foreign-born workers with managerial duties is critical to explain the reduction of transaction costs caused by migrant networks.

Epidemiology and patterns of tracheostomy practice in patients with acute respiratory distress syndrome in ICUs across 50 countries

2018

Background: To better understand the epidemiology and patterns of tracheostomy practice for patients with acute respiratory distress syndrome (ARDS), we investigated the current usage of tracheostomy in patients with ARDS recruited into the Large Observational Study to Understand the Global Impact of Severe Acute Respiratory Failure (LUNG-SAFE) study. Methods: This is a secondary analysis of LUNG-SAFE, an international, multicenter, prospective cohort study of patients receiving invasive or noninvasive ventilation in 50 countries spanning 5 continents. The study was carried out over 4 weeks consecutively in the winter of 2014, and 459 ICUs participated. We evaluated the clinical characteris…

Immunocompromised patients with acute respiratory distress syndrome: Secondary analysis of the LUNG SAFE database

2018

Background: The aim of this study was to describe data on epidemiology, ventilatory management, and outcome of acute respiratory distress syndrome (ARDS) in immunocompromised patients. Methods: We performed a post hoc analysis on the cohort of immunocompromised patients enrolled in the Large Observational Study to Understand the Global Impact of Severe Acute Respiratory Failure (LUNG SAFE) study. The LUNG SAFE study was an international, prospective study including hypoxemic patients in 459 ICUs from 50 countries across 5 continents. Results: Of 2813 patients with ARDS, 584 (20.8%) were immunocompromised, 38.9% of whom had an unspecified cause. Pneumonia, nonpulmonary sepsis, and noncardiog…

Economic evaluation of a guided and unguided internet-based CBT intervention for major depression: Results from a multicenter, three-armed randomized…

2017

Depression is one of the most common mental disorders and will become one of the leading causes of disability in the world. Internet-based CBT programs for depression have been classified as well established following the American Psychological Association criteria for empirically supported treatments. The aim of this study is to analyze the cost effectiveness at 12-month follow-up of the Internet-based CBT program Smiling is fun with (LITG) and without psychotherapist support (TSG) compared to usual care. The perspective used in our analysis is societal. A sample of 296 depressed patients (mean age of 43.04 years; 76% female; BDI-II mean score = 22.37) from primary care services in four Sp…

Aplicabilidad de un Score de TCAR para determinar la gravedad y el pronóstico en el momento del diagnóstico de la fibrosis pulmonar idiopática.

2016

Introducción: La TCAR es una exploración de primer orden en el diagnóstico y seguimiento de la fibrosis pulmonar idiopática (FPI), sin embargo no se utiliza para ponderar la gravedad. Bajo la hipótesis de que cuantificar la extensión de FPI en TCAR sería muy útil para establecer la gravedad al diagnóstico y monitorizar su evolución, nos propusimos evaluar la utilidad de un score semicuantitativo de FPI en TCAR en relación con parámetros funcionales habitualmente empleados para establecer la gravedad y monitorizar la evolución del proceso fibrótico. Pacientes y Método: Estudio prospectivo incluyendo 48 pacientes consecutivos diagnosticados de FPI. Mediante un score semicuantitativo se puntuó…

Alteraciones hepáticas en la infección por covid-19 y sus implicaciones clínicas y pronósticas: estudio retrospectivo

2022

INTRODUCCIÓN: La alteración de la bioquímica hepática (ABH) en pacientes con afectación clínica respiratoria por COVID-19 es frecuente y se ha relacionado con la aparición de eventos clínicos desfavorables. Nuestro objetivo principal es determinar si ABH es un factor pronóstico negativo independiente en estos pacientes. PACIENTES Y MÉTODOS: Determinamos la capacidad pronóstica de ABH mediante tres cohortes retrospectivas de adultos con COVID-19. Las dos primeras fueron pacientes de los primeros 12 meses de pandemia (antes de la vacunación masiva): una unicéntrica de pacientes sin hepatopatía y otra multicéntrica con hepatopatía previa. La tercera fue unicéntrica con pacientes vacunados para…

La unidad de la verdad y la pluralidad de las culturas en Simone Weil

2016

A mi modo de ver, la tesis de Weil de la existencia de una verdad universal en una pluralidad de culturas resulta ser una aportación al problema del diálogo intercultural e interreligioso, que merece ser considerada en tanto supone una postura que difícilmente encuentra parangón. Una convivencia auténtica de los seres humanos y sus sociedades pasa irremisiblemente, a ojos de esta pensadora, por el esfuerzo siempre renovado de hacer lo imposible por realizar la verdad en la vida individual y colectiva de los pueblos. Sólo desde ese afán compartido, desde esa construcción espiritual de los hombres y sus sociedades, puede reconocerse aquella esfera común que los seres humanos, por el hecho de …
