    Physical and chemical characterization of PLA nanofibres and PLA/ZrO2 mesoporous composites synthesized by air-jet spinning

    Polylactic acid with zirconium oxide solution has been deposited by air-jet spinning to obtain a PLA/ZrO2 composite.Zirconium oxide is obtained by hydrothermal technique and the results indicate that zirconia is nanostructured, mesoporousand thermally stable. The precursor solutions are formed by different amounts of PLA and zirconia. PLA/ZrO2 composite isformed by nanofibres with a random distribution, non-porous and with diameter of fibres depending of PLA and zirconiaconcentrations. It is found that the incorporation of zirconia makes the PLA fibres harder, less flexible and mesoporous.However, the thermal properties are not affected by the zirconia incorporation. The findings show that PLA/ZrO2 compositecan be utilized as biomaterial

    Introduction and objective: Major bleeding events in patients undergoing left atrial appendage closure (LAAC) range from 2.2 to 10.3 per 100 patient-years in di erent series. This study aimed to clarify the bleeding predictive factors that could influence these di erences. Methods: LAAC was performed in 598 patients from the Iberian Registry II (1093 patient-years; median, 75.4 years). We conducted a multivariate analysis to identify predictive risk factors for major bleeding events. The occurrence of thromboembolic and bleeding events was compared to rates expected from CHA2DS2-VASc (congestive heart failure, hypertension, age, diabetes, stroke history, vascular disease, sex) and HAS-BLED (hypertension, abnormal renal and liver function, stroke, bleeding, labile INR, elderly, drugs or alcohol) scores. Results: Cox regression analysis revealed that age 75 years (HR: 2.5; 95% CI: 1.3 to 4.8; p = 0.004) and a history of gastrointestinal bleeding (GIB) (HR: 2.1; 95% CI: 1.1 to 3.9; p = 0.020) were two factors independently associated with major bleeding during follow-up. Patients aged <75 or 75 years had median CHA2DS2-VASc scores of 4 (IQR: 2) and 5 (IQR: 2), respectively (p < 0.001) and HAS-BLED scores were 3 (IQR: 1) and 3 (IQR: 1) for each group (p = 0.007). Events presented as follow-up adjusted rates according to age groups were stroke (1.2% vs. 2.9%; HR: 2.4, p = 0.12) and major bleeding (3.7 vs. 9.0 per 100 patient-years; HR: 2.4, p = 0.002). Expected major bleedings according to HAS-BLED scores were 6.2% vs. 6.6%, respectively. In patients with GIB history, major bleeding events were 6.1% patient-years (HAS-BLED score was 3.8 1.1) compared to 2.7% patients-year in patients with no previous GIB history (HAS-BLED score was 3.4 1.2; p = 0.029). Conclusions: In this high-risk population, GIB history and age 75 years are the main predictors of major bleeding events after LAAC, especially during the first year. Age seems to have a greater influence on major bleeding events than on thromboembolic risk in these patient

    Curso abierto de ayuda para la elaboración del Trabajo Fin de Grado en los Grados en Química e Ingeniería Química

    Get PDF
    Este proyecto llevará a cabo el desarrollo de un curso abierto que sirva a los estudiantes como guía de ayuda a la hora de elaborar su Trabajo Fin de Grado (TFG) en los Grados de Química e Ingeniería Química. Se incluirá una descripción de herramientas que los estudiantes puedan emplear en el desarrollo de sus TFG. Éstas serán seleccionadas de acuerdo con la experiencia de los miembros del Grupo y en función de las necesidades de los estudiantes. El curso resultante se editará para libre acceso a través del portal iTunes U, de ámbito internacional, convirtiéndose en el primer curso UCM ofertado en esta plataforma (tras consulta y aprobación del Vicerrectorado de Innovación; de no ser así, se alojará en alguna otra plataforma de amplia difusión). Se aprovechará la accesibilidad ofertada a los estudiantes por iTunes U para poner a su disposición el material elaborado logrando una gran difusión, incrementándose la visibilidad internacional de la UCM. El material de ayuda elaborado para el curso se presentará tanto en español como en inglés, para facilitar su uso por alumnos visitantes de la UCM, favoreciendo la movilidad de los estudiantes en el marco del EEES. Este material también se adaptará para poder ser empleado de forma directa, totalmente o en forma de módulos, en el Campus Virtual UCM

    A new group of Palaeolithic painted hands from the southern Iberian Peninsula. Las Estrellas cave (Castellar de la Frontera, Cádiz)

    Get PDF
    This work presents a review of the rock art conserved at a site located in the autonomous community of Andalusia, known in the preceding literature as the Las Estrellas cave (Castellar de la Frontera, Cádiz). This is a large open-air rocky shelter, in which various schematic style pictographs were found, in the early years of this century. During a recent visit to the site, the existence of an important Palaeolithic figurative set was also noted, which includes representations of fauna and a small series of outlines of hands. This article deals with the generic analysis of the art catalogued in the cave up to the present moment, paying special attention to the set of the aforementioned Palaeolithic handprints, which have been documented using digital 3d technology. Similarly, its contextualization in Andalusian Palaeolithic art will be taken into account and a first chronological approximation of this interesting and varied figurative system will be made.Presentamos en este trabajo la revisión de las manifestaciones de arte rupestre conservadas en una estación localizada en la comunidad autónoma de Andalucía, conocida en la literatura precedente como cueva de Las Estrellas (Castellar de la Frontera, Cádiz). Se trata de un abrigo rocoso de grandes dimensiones, abierto al aire libre, en el que ya se había constatado, en los primeros años del presente siglo, la presencia de diversas pictografías de estilo esquemático. Durante una visita reciente al enclave se ha advertido, además, la existencia de un importante conjunto figurativo de cronología paleolítica que incluye representaciones de fauna y una pequeña serie de improntas de manos en negativo. Este artículo aborda el análisis genérico de las grafías catalogadas hasta el momento en la cavidad, atendiendo con especial detalle al conjunto de las citadas huellas de manos paleolíticas, que han sido documentadas usando tecnología digital 3d. De igual modo, se tendrán en cuenta su contextualización en el arte paleolítico andaluz y una primera aproximación cronológica a este interesante y variado complejo figurativo

    Incidence, Clinical Characteristics and Management of Inflammatory Bowel Disease in Spain : Large-Scale Epidemiological Study

    Get PDF
    (1) Aims: To assess the incidence of inflammatory bowel disease (IBD) in Spain, to describe the main epidemiological and clinical characteristics at diagnosis and the evolution of the disease, and to explore the use of drug treatments. (2) Methods: Prospective, population-based nationwide registry. Adult patients diagnosed with IBD-Crohn's disease (CD), ulcerative colitis (UC) or IBD unclassified (IBD-U)-during 2017 in Spain were included and were followed-up for 1 year. (3) Results: We identified 3611 incident cases of IBD diagnosed during 2017 in 108 hospitals covering over 22 million inhabitants. The overall incidence (cases/100,000 person-years) was 16 for IBD, 7.5 for CD, 8 for UC, and 0.5 for IBD-U; 53% of patients were male and median age was 43 years (interquartile range = 31-56 years). During a median 12-month follow-up, 34% of patients were treated with systemic steroids, 25% with immunomodulators, 15% with biologics and 5.6% underwent surgery. The percentage of patients under these treatments was significantly higher in CD than UC and IBD-U. Use of systemic steroids and biologics was significantly higher in hospitals with high resources. In total, 28% of patients were hospitalized (35% CD and 22% UC patients, p < 0.01). (4) Conclusion: The incidence of IBD in Spain is rather high and similar to that reported in Northern Europe. IBD patients require substantial therapeutic resources, which are greater in CD and in hospitals with high resources, and much higher than previously reported. One third of patients are hospitalized in the first year after diagnosis and a relevant proportion undergo surgery
