De la riḥla de Ibn Yubayr y de los lugares santos de Damasco

Pendant son séjour en Syrie, Ibn Jubayr a fait d'intéressantes descriptions des lieux de Damas. Sa terre a été considérée résidence de saints et de frontière. Dans son territoire une grand quantité de cavernes jouissaient d'un grand prestige biblique, spécialement celles situées dans le versant du mont Qasiyun. Les cavernes étaient un symbole de la vie érémitique que dans son temps commencent à être des monastères (khanqa ou ribāṭ). Ce fait nous parle de nouvelles formes institutionalisées d'ascétisme. C'est justement à ce moment-là qu'est née la confrérie mystique, qui va s'étendre sur toute la géographie de l'Islam. Ibn Jubayr, comme témoin d'exception, nous éclaire sur ces changements.Grâce donc à son œuvre, nous pouvons compléter un peu plus notre savoir au sujet de l'histoire de la Syrie, au Moyen Âge.During his stay in Syria, Ibn Jubayr makes a very interesting description of the lands of Damascus. The area was considered residence of saints as well as a frontier. Some of the caves found in there were believed to have biblical prestige, especially those on the slopes of the Qasiyun mount, beside Damascus. The caves were a symbol of hermitry, some of them even becoming monasteries (khanqa or ribāṭ). These facts tell us about new institutionalized forms of asceticism. It is precisely during that period when the institution of the religious brotherhood is born and then spread all over the islamic world. Ibn Jubayr is an exceptional witness to this process and, thanks to his work, we can complete our vision of the history of Syria in the middle ages

Los judíos en las fuentes andalusíes y magrebíes: los visires

RESUMEN: Después de establecer un corpus de fuentes arábigas –dando en diversos apéndices traducción de ciertos textos nunca antes vertidos a una lengua europea– y luego de examinar los trabajos más representativos existentes acerca del poder ejercido por visires judíos en al-Andalus se llega a las siguientes conclusiones: No hubo ejércitos judíos en ninguna época en al-Andalus, y ningún judío comandó ejércitos musulmanes. Cierto es que por su cultura superior algunos judíos llegaron a ser visires y secretarios de reyes, especialmente en la época de las taifas. A lo largo de esta investigación se demuestra que la posición de estos prohombres judíos, por su calidad de dimmíes, protegidos de la comunidad musulmana, fue de naturaleza inestable, cuando no provisional, y sujeta a mil asechanzas, intrigas y peligros.ABSTRACT: After selecting a quantity of texts from Arabic sources –some of them never translated before into a Western language– and after looking through the main works about the extent of the power wielded by the Jewish viziers in al-Andalus, we have arrived to the following conclusions: There was never a Jewish army in al-Andalus or any Muslim army commanded by a Jew; It is true that due to their refinement some of them obtained important posts, such as viziers and court secretaries, specially during the Taifa Period. Throughout this research it is shown that these outstanding men, protected by the Muslim community in their Dimmi status was in fact a very unstable and provisional position, subjected many times to many intrigues and dangers.</p

La peculiaridad histórica del Yemen en el contexto árabo-islámico (desde la Reina de Saba al Yemen actual)

[ES]Yemen es la tierra de la Reina de Saba y el lugar donde se desarrolló la civilización sudarábiga, tiene una extensión de 527.968 km². En árabe Yaman significa “país del Sur”, opuesto a Sham (Siria, Damasco) “país del Norte”. El Yemen es por su posición geográfica, gracias al monzón, el núcleo verde de la península de Arabia, la más grande del mundo, una península sin ríos, conformada por estepas áridas y desiertos salpicados por raros oasis.[EN]Yemen is the land of the Queen of Sheba and the place where civilization developed sudarábiga, has an area of 527 968 km ². Yaman Arabic means "country of the South", as opposed to Sham (Syria, Damascus) "North Country." Yemen is by its geographical position, thanks to the monsoon, the green heart of the Arabian Peninsula, the largest in the world, a peninsula with no river, consisting of arid steppes and deserts dotted with rare oasis

Prevalence of bleeding secondary to anticoagulation and mortality in patients with atrial fibrillation admitted with SARS-CoV-2 infection.

Atrial fibrillation (AF) is common in patients admitted with severe COVID-19. However, there is limited data about the management of chronic anticoagulation therapy in these patients. We assessed the anticoagulation and incidence of major cardiovascular events in hospitalized patients with AF and COVID-19. We retrospectively investigated all consecutive patients with AF admitted with COVID-19 between March and May 2020 in 9 Spanish hospitals. We selected a control group of non-AF patients consecutively admitted with COVID-19. We compared baseline characteristics, incidence of major bleeding, thrombotic events and mortality. We used propensity score matching (PSM) to minimize potential confounding variables, as well as a multivariate analysis to predict major bleeding and death. 305 patients admitted with AF and COVID-19 were included. After PSM, 151 AF patients were matched with 151 control group patients. During admission, low-molecular-weight heparin was the principal anticoagulant and the incidence of major bleeding and mortality were higher in the AF group [16 (10.6%) vs 3 (2%), p=0.003; 52 (34.4%) vs 35 (23.2%), p=0.03, respectively]. The multivariate analysis showed the presence of AF as independent predictor of in-hospital major bleeding and mortality in COVID-19 patients. In AF group, a secondary multivariate analysis identified high levels of D-dimer as independent predictor of in-hospital major bleeding. AF patients admitted with COVID-19 represent a population at high risk for bleeding and mortality during admission. It seems advisable to individualize anticoagulation therapy during admission, considering patient specific bleeding and thrombotic risk.S
