Mutilaciones en escultura. Análisis de casos

El Trabajo de Final de Grado “Mutilaciones en Escultura: Análisis de casos” versa sobre el análisis y cálculo de las distintas zonas de mutilaciones sufridas por cuatro casos distintos. En la primera parte del trabajo se expone qué es la mutilación y cómo ha sido tratada a lo largo de la historia, además del planteamiento de una metodología que sirve para el cálculo de los faltantes en relación al porcentaje total de la obra conservada en la actualidad. Además, se plantea una breve propuesta de intervención de cada una de las obras atendiendo los principales problemas que presenta la piedra que la constituye.Ferrer Ventura, M. (2014).

First approach to the intervention of the paleo-ichnological heritage on "La Virgen del Campo" site. Enciso, La Rioja (Spain)

[ES] En el presente trabajo. se analiza el estado de conservación del yacimiento paleoicnológico de La Virgen del Campo, situado en Enciso, La Rioja (España). En primer lugar, se realiza una revision bibliográfica y búsqueda de las intervenciones realizadas en el yacimiento y los materiales que se aplicaron. Por otro lado, se realize un studio del estado de conservación y las causas de deterioro y las patologías presentes en el yacimiento. Dichas patologías, se identifican y se asignan a una categoría concreta gracias al glosario del ICOMOS. Por otro lado, se realiza una propuesta de intervención. Esta propuesta de intervención se realiza gracias a la revision bibliográdica y los estudios preliminaries llevados a cabo en el laboratorio. Finalmente, se realiza un studio de los materiales de restauración, especialmente centrado en los diferentes tipos de morteros de cal, testeando la compatiblidad con la piedra del yacimiento en el laboratorio y durante la campaña de campo.[EN] In this paper, we analysed the state of conservation of the paleoichnological site of La Virgen del Campo located in Enciso, La Rioja, (Spain). First, a bibliographic review was carried out, researching about the interventions made on the site and the materials applied. We made a conservation study, in which we analysed the causes of deterioration, using different methods, and pathologies. These pathologies are identified and assigned to a defined category according to ICOMOS glossary. In addition, we carried out an intervention proposal. This has been done, thanks to the bibliographic review and the studies that we accomplished at the laboratory. Finally, we made a study of the restoration materials, specially focused on different lime mortars. We tested their suitability with the rock of the site at the laboratory and then during the field season.Ferrer Ventura, M.; Mas Barberà, X.; Torices, A.; San Juan-Palacios, R.; Navarro-Lorbés, P.

Dinosaur swim tracks from the Lower Cretaceous of La Rioja, Spain: An ichnological approach to non-common behaviours

The reconstruction of behavioural patterns performed by non-avian dinosaurs is an important task of palaeontology in order to globally understand how these animals interacted with their environment. Their relation with aquatic lifestyles has always been an intriguing question that has been extensively studied during the last decades, especially focused on some specific groups. The present work describes a new tracksite with 27 swimming tracks located in a fluvial setting from the Lower Cretaceous Urbion Group of La Rioja (Spain). They are preserved as natural casts with sizes between 8.5 and 29.2 cm and a predominant orientation. The tracks have been classified into 6 different morphotypes according to their morphology, and grouped into 5 different categories depending on the different pes-substrate interactions, following the proposal of Romilio et al. (2013). Some tracks were produced while the animal was moving in partial or complete buoyancy, and displacement was conducted by water and sediment impulsion, not just a mere paddling. Other tracks could be impressed in a bottom-walked, when the trackmaker touched the digit tips on the ground vertically or sub-vertically. This new tracksite confirms the capabilities of some groups of non-avian dinosaurs to interact with shallow water environments where they could print their pedes as they moved, either in complete buoyancy or during a displacement with some vertical component in the water column. It also contributes to the better understanding of swimming track morphologies as especially dependent on pes-sediment interaction and environment more than differences in pes configuration itself, causing the high variability of swimming footprints even when they belong to the same trackway. The classification of swimming tracks and footprints into categories dependent on the pes-substrate interaction could be a good guiding principle to avoid problematics about ichnotaxonomical definition.Depto. de Geodinámica, Estratigrafía y PaleontologíaFac. de Ciencias GeológicasTRUEUniversidad de La RiojaConsejeria de Educacion y Cultura (Gobierno de La Rioja)Instituto de Estudios RiojanosMinisterio de Ciencia, Innovación y UniversidadesEuropean Regional Development FundUniversidad del País VascoMinisterio de Ciencia e Innovaciónpu

Más allá de los dinosaurios: nuevas perspectivas para el patrimonio paleontológico de La Rioja

El patrimonio paleontológico en nuestro país ha sido objeto de discusión entre científicos y legisladores desde su controvertida consideración dentro del patrimonio histórico en la Ley 16/1985, de 25 de junio, del Patrimonio Histórico Español. Así, tanto el patrimonio inmueble (yacimientos) como el mueble (ejemplares ex situ alojados en museos, colecciones y exposiciones locales) se gestionaron durante años bajo esta norma hasta su inclusión, en el año 2007, en la nueva Ley 42/2007, de 13 de diciembre, de Patrimonio Natural y Biodiversidad.Fil: García Ortiz de Landaluce, Esperanza.

Patient Experience in Pancreas-Kidney Transplantation-A Methodological Approach Towards Innovation in an Established Program

Simultaneous pancreas-kidney transplantation (SPKT) leads to increased survival and quality of life, and is an alternative treatment for insulin-dependent diabetes mellitus and end-stage kidney disease. Due to the particularities of this population (often with multiple comorbidities) and of the surgery (only performed in a few centers), a comprehensive analysis of patients' experience along the SPKT process is crucial to improve patient care and add value to this procedure. Therefore, we applied a systematic and iterative methodology with the participation of both patients and professional teams working together to explore and identify unmet needs and value-adding steps along the transplant patient journey at an established pancreas transplant program. Four main steps (to comprehend, to explore, to experiment and to assess) led to several interventions around three major areas: Administration and logistics, information and communication, and perceived quality of assistance. As a result, both displacements to the hospital for diagnostic purposes and the time delay involved in joining the patient waiting list for transplantation were reduced in parallel to the administrative procedures. In conclusion, the methodological implementation of key organizational changes has great impact on overall patient experience. Further quantitative analysis from the patient's perspective will consolidate our program and may add new prototype service design components

Preemptive simultaneous pancreas kidney transplantation has survival benefit to patients

Several organ allocation protocols give priority to wait-listed simultaneous kidney-pancreas (SPK) transplant recipients to mitigate the higher cardiovascular risk of patients with diabetes mellitus on dialysis. The available information regarding the impact of preemptive simultaneous kidney-pancreas transplantation on recipient and graft outcomes is nonetheless controversial. To help resolve this, we explored the influence of preemptive simultaneous kidney-pancreas transplants on patient and graft survival through a retrospective analysis of the OPTN/UNOS database, encompassing 9690 simultaneous transplant recipients between 2000 and 2017. Statistical analysis was performed applying a propensity score analysis to minimize bias. Of these patients, 1796 (19%) were transplanted preemptively. At ten years, recipient survival was significantly superior in the preemptive group when compared to the non-preemptive group (78.9% vs 71.8%). Dialysis at simultaneous kidney-pancreas transplantation was an independent significant risk for patient survival (hazard ratio 1.66 [95% confidence interval 1.32-2.09]), especially if the dialysis duration was 12 months or longer. Preemptive transplantation was also associated with significant superior kidney graft survival compared to those on dialysis (death-censored: 84.3% vs 75.4%, respectively; estimated half-life of 38.57 [38.33 -38.81] vs 22.35 [22.17 - 22.53] years, respectively). No differences were observed between both groups neither for pancreas graft survival nor for post-transplant surgical complications. Thus, our results sustain the relevance of early referral for pancreas transplantation and the importance of pancreas allocation priority in reducing patient mortality after simultaneous kidney-pancreas transplantation

COVID-19 symptoms at hospital admission vary with age and sex: results from the ISARIC prospective multinational observational study

Background: The ISARIC prospective multinational observational study is the largest cohort of hospitalized patients with COVID-19. We present relationships of age, sex, and nationality to presenting symptoms. Methods: International, prospective observational study of 60 109 hospitalized symptomatic patients with laboratory-confirmed COVID-19 recruited from 43 countries between 30 January and 3 August 2020. Logistic regression was performed to evaluate relationships of age and sex to published COVID-19 case definitions and the most commonly reported symptoms. Results: ‘Typical’ symptoms of fever (69%), cough (68%) and shortness of breath (66%) were the most commonly reported. 92% of patients experienced at least one of these. Prevalence of typical symptoms was greatest in 30- to 60-year-olds (respectively 80, 79, 69%; at least one 95%). They were reported less frequently in children (≤ 18 years: 69, 48, 23; 85%), older adults (≥ 70 years: 61, 62, 65; 90%), and women (66, 66, 64; 90%; vs. men 71, 70, 67; 93%, each P < 0.001). The most common atypical presentations under 60 years of age were nausea and vomiting and abdominal pain, and over 60 years was confusion. Regression models showed significant differences in symptoms with sex, age and country. Interpretation: This international collaboration has allowed us to report reliable symptom data from the largest cohort of patients admitted to hospital with COVID-19. Adults over 60 and children admitted to hospital with COVID-19 are less likely to present with typical symptoms. Nausea and vomiting are common atypical presentations under 30 years. Confusion is a frequent atypical presentation of COVID-19 in adults over 60 years. Women are less likely to experience typical symptoms than men
