Relevance of gastrointestinal manifestations in a large Spanish cohort of patients with systemic lupus erythematosus: what do we know?

SLE can affect any part of the gastrointestinal (GI) tract. GI symptoms are reported to occur in >50% of SLE patients. To describe the GI manifestations of SLE in the RELESSER (Registry of SLE Patients of the Spanish Society of Rheumatology) cohort and to determine whether these are associated with a more severe disease, damage accrual and a worse prognosis. METHODS: We conducted a nationwide, retrospective, multicentre, cross-sectional cohort study of 3658 SLE patients who fulfil =4 ACR-97 criteria. Data on demographics, disease characteristics, activity (SLEDAI-2K or BILAG), damage (SLICC/ACR/DI) and therapies were collected. Demographic and clinical characteristics were compared between lupus patients with and without GI damage to establish whether GI damage is associated with a more severe disease. RESULTS: From 3654 lupus patients, 3.7% developed GI damage. Patients in this group (group 1) were older, they had longer disease duration, and were more likely to have vasculitis, renal disease and serositis than patients without GI damage (group 2). Hospitalizations and mortality were significantly higher in group 1. Patients in group 1 had higher modified SDI (SLICC Damage Index). The presence of oral ulcers reduced the risk of developing damage in 33% of patients. CONCLUSION: Having GI damage is associated with a worse prognosis. Patients on a high dose of glucocorticoids are at higher risk of developing GI damage which reinforces the strategy of minimizing glucocorticoids. Oral ulcers appear to decrease the risk of GI damage. © The Author(s) 2021. Published by Oxford University Press on behalf of the British Society for Rheumatology

Encuadre bioclimático de algunas variedades de "Olea Europeae L." en el Sur de España

En el presente trabajo se relaciona la investigación bioclimática y agrícola. Se propone un modelo específico, basado en datos bioclimáticos y fitosociológicos, que incremente la producción en cuanto a calidad y cantidad con el mínimo coste ambiental. Dicho estudio bioclimático se ha realizado para diferentes variedades de olivo en el centro-sur de la Península Ibérica

Deformation style and controlling geodynamic processes at the eastern Guadalquivir foreland basin (Southern Spain)

The tectonic structure of the Guadalquivir foreland basin becomes complex eastward evolving from a single depocenter to a compartmented basin. The deformation pattern within the eastern Guadalquivir foreland basin has been characterized by combining seismic reflection profiles, boreholes, and structural field data to output a 3‐D model. High‐dipping NNE‐SSW to NE‐SW trending normal and reverse fault arrays deform the Variscan basement of the basin. These faults generally affect Tortonian sediments, which show syntectonic features sealed by the latest Miocene units. Curved and S‐shaped fault traces are abundant and caused by the linkage of nearby fault segments during lateral fault propagation. Preexisting faults were reactivated either as normal or reverse faults depending on their position within the foreland. At Tortonian time, reverse faults deformed the basin forebulge, while normal faults predominated within the backbulge. Along‐strike variation of the Betic foreland basin geometry is supported by an increasing mechanical coupling of the two plates (Alborán Domain and Variscan basement) toward the eastern part of the cordillera. Thus, subduction would have progressed in the western Betics, while it would have failed in the eastern one. There, the initially subducted Iberian paleomargin (Nevado‐Filábride Complex) was incorporated into the upper plate promoting the transmission of collision‐related compressional stresses into the foreland since the middle Miocene. Nowadays, compression is still active and produces low‐magnitude earthquakes likely linked to NNE‐SSW to NE‐SW preexiting faults reactivated with reverse oblique‐slip kinematics. Seismicity is mostly concentrated around fault tips that are frequently curved in overstepping zones.Instituto Geológico y Minero de España, EspañaDepartamento de Física, Universidad de Jaén, Españ

Estudios de los quejigares de Sierra Morena Occidental

Se estudian los bosques de quejigo en el suroeste de la Península Ibérica, poniendo de manifiesto su composición floristica, distribución biogeográfica y ecológica. Además se realiza un estudio bioclimático territorial que sirve de base para el establecimiento de estas formaciones. En este análisis sobre los quejigares de Sierra Morena Oriental se obtienen 2 asociaciones. Presentándose en estos territorios más orientales y por tanto con menor influencia atlántica, sobre sustratos silíceos, suelos profundos y ombrotipo subhúmedo e influencia continental de la meseta peninsular, bosques de Quercus broteroi, Pyro bourgaeanae-Quercetum broteroi; en estos mismos territorios pero en barrancos más húmedos y resguardados de los fríos de la meseta se encuentran bosques de Pistado terebinthi-Quercetum broteroi Rivas Goday in Rivas Goday, Borja, Esteve, Galiano, Rigual & Rivas-Martínez 1960, sintaxon descrito por sus autores para el occidente de la Península, por lo que con esta aportación ampliamos su área geográfica de distribución
