re-habitar El Carmen : Un proyecto sobre patrimonio contemporáneo

El proyecto _re-HABITAR suponía para el propio proceder de la institución un avance más allá del reconocimiento, registro, inventario o protección patrimonial de la arquitectura del siglo XX y del Movimiento Moderno para posicionarse en la acción preventiva y conservativa de ese legado contemporáneo. Para ello, la praxis patrimonial se aferraba a un modelo: el de la vivienda social en España en la segunda mitad del siglo XX; a un caso concreto: el de la barriada de Nuestra Señora del Carmen (Recasens Méndez-Queipo de Llano, 1958); y a un requisito fundamental: analizar un objeto vivo y en uso, aún con la presencia de quienes lo vivieron y usaron desde su origen

Distribution of critical metals in evolving pyrite from massive sulfide ores of the Iberian Pyrite Belt

With >90 known deposits containing original reserves of >2400 Mt of sulfide ore, the Iberian Pyrite Belt (IPB) is the largest volcanogenic massive sulfide (VMS) province on Earth. In these evolving mineral systems, texturally different pyrite exhibits characteristic mineralogy and trace element fingerprints. Pyrite (Py-1), which is well preserved in the polymetallic ores that crystallized at the earliest stage of VMS deposit formation, consists of kernels of pyrite framboids surrounded by concentric colloform bands and ended by faceted outlines. It is rich in some metals like Pb, Zn, Sb and As (mostly hosted as nano-to-micron-sized particles, including galena, tetrahedrite and arsenopyrite) but depleted in Cu, Co and Bi. In contrast, pyrite from the pyritic and Cu-rich ore overprinted by late fluids exhibits spongy-looking (Py-2) or homogenous (Py-3) cores surrounded by external facets with crystallographic continuity across the whole single grains due to re-crystallization. Py-2 is depleted in most trace elements with the exception of Au and Bi, which occur both in solid solutions and as nano-to-micron-sized inclusions. Py-3 has the highest Cu, Ag, Co and Ni (mainly associated to nano-to-micron-sized particles of tennantite, chalcopyrite and gersdorffite) and the lowest Au contents in the form of native gold. The progressive increase in metal contents from inner to outer parts of Py-1 matches with the onset of the economic metal endowment of VMS deposits in the IPB, whereas Py-2 and Py-3 are associated with metal shoot processes that led to both leached and high-grade ores, very likely when mafic rocks were emplaced into the footwall of the deposits

Evaluation of the impact of nursing clinics in the rheumatology services

Nursing clinics in rheumatology (NCRs) are organisational care models that provide care centred within the scope of a nurse’s abilities. To analyse the impact of NCR in the rheumatology services, national multicenter observational prospective cohort studied 1-year follow-up, comparing patients attending rheumatology services with and without NCR. NCR was defined by the presence of: (1) office itself; (2) at least one dedicated nurse; and (3) its own appointment schedule. Variables included were (baseline, 6 and 12 months): (a) test to evaluate clinical activity of the disease, research and training, infrastructure of unit and resources of NCR and (b) tests to evaluate socio-demographics, work productivity (WPAI), use of services and treatments and quality of life. A total of 393 rheumatoid arthritis and ankylosing spondylitis patients were included: 181 NCR and 212 not NCR, corresponding to 39 units, 21 with NCR and 18 without NCR (age 53 + 11.8 vs 56 + 13.5 years). Statistically significant differences were found in patients attended in sites without NCR, at some of the visits (baseline, 6 or 12 months), for the following parameters: higher CRP level (5.9 mg/l ± 8.3 vs 4.8 mg/l ± 7.8; p < 0.005), global disease evaluation by the patient (3.6 ± 2.3 vs 3.1 ± 2.4), physician (2.9 ± 2.1 vs 2.3 ± 2.1; p < 0.05), use of primary care consultations (2.7 ± 5.4 vs 1.4 ± 2.3; p < 0.001) and worse work productivity. The presence of NCR in the rheumatology services contributes to improve some clinical outcomes, a lower frequency of primary care consultations and better work productivity of patients with rheumatic diseases.Sin financiación1.824 JCR (2016) Q3, 21/30 RheumatologyUE

Consenso ASAS en nomenclatura en español para las espondiloartritis (Assessment of SpondyloArthritis International Society (ASAS) Consensus on Spanish Nomenclature for Spondyloarthritis)

Objetivo: Desarrollar un documento de consenso para estandarizar los términos, abreviaturas y acrónimos en español empleados en el campo de las espondiloartritis (EspA). Métodos: Se creó un grupo de trabajo internacional compuesto por todos los miembros de Assessment of SpondyloArthritis International Society (ASAS) nativos de habla española, miembros del comité ejecutivo del Grupo para el estudio de la Espondiloartritis de la Sociedad Española de Reumatología (GRESSER), 2 metodólogos, 2 lingüistas de la Real Academia Nacional de Medicina de España (RANM) y 2 pacientes de la Coordinadora Española de Asociaciones de Espondilitis (CEADE). Se realizó una revisión de la literatura de los últimos 15 años (publicaciones, el CIE y CIF, guías, consensos y recomendaciones) para identificar los términos, abreviaturas y acrónimos discrepantes. Mediante un Delphi de 3 rondas y una reunión presencial, se discutieron, seleccionaron y acordaron los términos, abreviaturas y acrónimos a utilizar. Durante todo este proceso se siguieron las recomendaciones de la RANM basadas en el Diccionario panhispánico de términos médicos. Resultados: Se consensuaron 46 términos, abreviaturas y acrónimos. Se aceptó la traducción al español para 6 términos y 6 abreviaturas empleados para nombrar o clasificar la enfermedad y para 6 términos y 4 abreviaturas relacionados con las EspA. Se acordó no traducir 15 acrónimos por estar ya establecidos, pero al mencionarlos, se recomendó seguir esta estructura: tipo de acrónimo en español y acrónimo y forma extensa en inglés. Con respecto a 7 términos o abreviaturas asociados a acrónimos, se acordó traducir solo la forma extensa y se consensuó una traducción. Conclusiones: Con esta estandarización del lenguaje de las EspA se pretende establecer un uso común de la nomenclatura en español para las EspA. Su implementación será muy beneficiosa, evitando malentendidos y consumo de recursos. (Objective: To develop a consensus to standardize the use of Spanish terms, abbreviations and acronyms in the field of spondyloarthritis (SpA). Methods: An international task force comprising all native Spanish-speaking Assessment of SpondyloArthritis International Society (ASAS) members, the executive committee of Grupo para el estudio de la Espondiloartritis de la Sociedad Española de Reumatología (GRESSER), two methodologists, two linguists from the Real Academia Nacional de Medicina de España (RANM) and two patients from the Spanish Coordinator of Spondylitis Associations (CEADE) was established. A literature review was performed to identify the conflicting terms/abbreviations/acronyms in SpA. This review examined written sources in Spanish including manuscripts, ICF and ICD, guidelines, recommendations and consensuses. This was followed by a nominal group meeting and a three-round Delphi. The recommendations from the RANM based on the Panhispanic dictionary were followed throughout the process. Results: Consensus was reached for 46 terms, abbreviations or acronyms related to the field of SpA. A Spanish translation was accepted for 6 terms and 6 abbreviations to name or classify the disease, and for 6 terms and 4 abbreviations related to SpA. It was agreed not to translate 15 acronyms into Spanish. However, when mentioning them, it was recommended to follow this structure: type of acronym in Spanish and acronym and expanded form in English. With regard to 7 terms or abbreviations attached to acronyms, it was agreed to translate only the expanded form and a translation was also selected for each of them. Conclusions: Through this standardization, it is expected to establish a common use of the Spanish nomenclature for SpA. The implementation of this consensus across the community will be of substantial benefit, avoiding misunderstandings and time-consuming processes.

Comparative Study of Infliximab Versus Adalimumab in Refractory Uveitis due to Behçet's Disease: National Multicenter Study of 177 Cases.

To compare the efficacy of infliximab (IFX) versus adalimumab (ADA) as a first-line biologic drug over 1 year of treatment in a large series of patients with refractory uveitis due to Behçet's disease (BD). We conducted an open-label multicenter study of IFX versus ADA for BD-related uveitis refractory to conventional nonbiologic treatment. IFX or ADA was chosen as the first-line biologic agent based on physician and patient agreement. Patients received 3-5 mg/kg intravenous IFX at 0, 2, and 6 weeks and every 4-8 weeks thereafter, or 40 mg subcutaneous ADA every other week without a loading dose. Ocular parameters were compared between the 2 groups. The study included 177 patients (316 affected eyes), of whom 103 received IFX and 74 received ADA. There were no significant baseline differences between treatment groups in main demographic features, previous therapy, or ocular sign severity. After 1 year of therapy, we observed an improvement in all ocular parameters in both groups. However, patients receiving ADA had significantly better outcomes in some parameters, including improvement in anterior chamber inflammation (92.31% versus 78.18% for IFX; P = 0.06), improvement in vitritis (93.33% versus 78.95% for IFX; P = 0.04), and best-corrected visual acuity (mean ± SD 0.81 ± 0.26 versus 0.67 ± 0.34 for IFX; P = 0.001). A nonsignificant difference was seen for macular thickness (mean ± SD 250.62 ± 36.85 for ADA versus 264.89 ± 59.74 for IFX; P = 0.15), and improvement in retinal vasculitis was similar between the 2 groups (95% for ADA versus 97% for IFX; P = 0.28). The drug retention rate was higher in the ADA group (95.24% versus 84.95% for IFX; P = 0.042). Although both IFX and ADA are efficacious in refractory BD-related uveitis, ADA appears to be associated with better outcomes than IFX after 1 year of follow-up
