Estudio técnico, historiográfico y proceso de intervención en "El Anacoreta", un lienzo inédito de José Vergara Gimeno (Valencia 1726-1799)

[EN] The subject of this Bachelor Thesis is a Valencian painting from the second half of the XVIII century. It is a study of an old man’s head, whose iconography could represent “Saint Anthony Penitent or simply an anchorite Saint”. Technically and, as one of the most important features, we can highlight that the painting has never been restored, keeping all his technical and material original components. This painting is an oil on canvas. The most important developed items for the project have been: the histo- ric-artistic study of the painting, its stylistic study, the technical study and the restoration of the work. All technical studies and the restoration have been done at the Laboratorio de Conservación y Restauración de Pintura de Caballete y Retablos at Universitat Politècnica de València. Fortunately, it could be realized a whole labour of conservation and restoration in all phases.[ES] La obra objeto del presente Trabajo Final de Grado es una pintura valenciana de la segunda mitad del siglo XVIII. Se trata de un estudio de cabeza de anciano que iconográficamente podría representar un ¿San Antonio Penitente o un Santo anacoreta¿. Técnicamente y como caracterísitica más importante cabe señalar que la obra no ha sido nunca intervenida a nivel de restauración manteniendo todos los componentes técnicos y matéricos originales. Está ejecutada en óleo sobre lienzo. Los puntos fundamentales desarrollados en el trabajo han sido: el estudio histórico-artístico de la obra, estilístico y técnico así como el procedimiento llevado a cabo en la restauración de la pieza. Tanto la realización de los análisis técnicos, como el procedimiento de restauración se realizaron en el taller y laboratorio de Conservación y Restauración de Pintura de Caballete y Retablos del Instituto de Restauración del Patrimonio de la Universitat Politècnica de València. Afortunadamente se ha podido realizar un trabajo íntegro de conservación y restauración en todas las fases.García Sanz, AL. (2016).

Un San Sebastián atribuido a Juan de Juanes procedente de la antigua colección Navarro Alcácer. Análisis técnico e historiográfico

Este Trabajo Final de Máster es el resultado del análisis e identificación de una pintura al óleo sobre tabla del siglo XVI con la representación de San Sebastián, en su tradicional representación martirial anudado a una columna, desnudo y con las flechas clavadas en su cuerpo. La tabla, proveniente de la antigua colección Navarro Alcacer, ha estado poco estudiada más allá del conocimiento de su existencia gracias a la primigenia atribución de Post a los Hernandos y su círculo (1953), de nuevo puesta en conocimiento de los estudiosos por Fernando Benito en el apéndice del catálogo Joan de Joanes. Una nueva visión del artista y su obra (2000). La obra, una pintura sobre paño de pino de pequeño tamaño (78.5 x 34.4 cm). Se incrementó de formato añadiendo dos listones de madera en sus lados verticales. Su estado de conservación es delicado; con grandes repintes al óleo, barnices oxidados, suciedad generalizada y grietas en la superficie, provocadas por las tensiones entre las uniones a través de piezas metálicas internas y los movimientos naturales de la madera original y la añadida. Para la asignación de la autoría de la obra, se han estudiado aspectos técnicos y artísticos, pudiéndose comprobar los grandes paralelismos existentes con la pintura propia de Juanes, especialmente la utilizada entre 1540-50, recabándose a lo largo del proceso de investigación datos suficientemente relevantes como para asignar la autoría de la obra al pintor más importante del manierismo valenciano. También se ha realizado un estudio de fuentes gráficas de las obras conocidas del pintor y de las obras de otros artistas contemporáneos, buscando paralelismos con obras de Juanes. Además, se ha desarrollado un estudio técnico de la obra, tanto con metodología no invasiva como invasiva, analizando las muestras en los laboratorios de la Universidad Politécnica de Valencia y el Instituto de Restauración del Patrimonio de dicho campus, comparándose los resultados con análisis técnicos de otras tablas de Juanes.The present Final Master's Work is the result of the analysis and identification of an oil painting panel of the sixteenth century from the Navaro Alcacer collection representing San Sebastian, in his traditional martyr attire, tied to a column, naked and with the arrows stuck into his body. Almost no studies of this table have been published so far, due its primitive attribution to Los Hernandos and their circle (1953). It was only later that it was brought to the attention of scholars by Fernando Benito in the appendix to the Joan de Joanes catalog: A new vision of the artist and his work (2000). The analyzed work consists in a painting on a small pine panel (78.5 x 34.4 cm). It s size was later increased by adding two wooden slats on both vertical sides. Its state of conservation is fragile; with large oil repaints, rusty varnishes, generalized dirt and cracks on the surface, caused by the tensions between the joints through internal metal parts and the natural movements of the original and added wood. Several technical and artistic aspects have been considered for the assignment of the authorship of the work, which led to confirm significant parallelisms with Juanes own work, especially with his paintings performed between 1540-50. As a consequence of this research process, enough relevant data were collected as to finally assign the authorship of the work to the most important painter of the Valencian mannerism. There has also been a benchmark study of graphic sources between the known works of the painter and those of other contemporary artists, in search of similarities with Juanes. In addition, a technical study of the work has been developed, both with non-invasive and invasive methodology, analyzing the samples in the laboratories of the Polytechnic University of Valencia and the Institute of Heritage Restoration of said campus, comparing the results with technical analysis of other tables from Juanes.García Sanz, AL.

Digitalización de documentos para generar recursos educativos virtuales

Las nuevas tecnologías y los medios digitales nos ofrecen nuevas posibilidades educativas: e-learning, entorno BYOD (Bring Your Own Device), etc. Los cursos abiertos (MOOCs) y los entornos de formación virtual (VLE) permiten el intercambio de contenido e información a través de diversos canales. Pero estos medios, por sí solos, no garantizan conseguir resultados de aprendizaje si no se cuentan con contenidos educativos adecuados. Estos modelos educativos no deben contar sólo con recursos “ex profeso” sino que deben apoyarse en materiales existentes de calidad, como libros de texto, artículos de revistas especializadas y fondos gráficos de los museos de la facultad. Sin embargo estos recursos no se encuentran en formato digital en nuestras bibliotecas aunque son muy demandados. La imposibilidad de hacer bases de datos de los documentos escaneados en la biblioteca, obliga al escaneo continuo de los ejemplares y por lo tanto sufren una manipulación por reutilización que puede afectar a su conservación. Así pues, la digitalización por escáner “cenital” es una solución útil para obtener contenidos digitales de documentos delicados o antiguos

Is Energy Expenditure or Physical Activity Considered When Energy Intake Is Measured? A Scoping Review 1975-2015

Support from the Spanish Nutrition Society (SEN) is highly acknowledged.The following are available online at https://www.mdpi.com/article/10 .3390/nu13093262/s1, Excel data review results.The health-transitions humans have delivered during the 20th Century associated with the nutrition is that from undernutrition to obesity, which perseveres in the current years of the 21st Century. Energy intake (EI) is a contributing factor and therefore a fascination in nutritional sciences. However, energy expenditure (EE) has not been usually considered as a conjoint factor. Thus, this study aimed to review if studies on adults consider data on dietary intake, specifically EI, and included data on EE and physical activity (PA). A search of MEDLINE from 1975 to December 2015 was managed. Our scoping review consisted of keywords related to EI, dietary allowances, and nutritional requirements. From 2229 acknowledged articles, 698 articles were finally taken fulfilling inclusion and quality criteria. A total of 2,081,824 adults (53.7% females) were involved, and most studies had been conducted in EEUU (241), Canada (42), Australia (30), Japan (32), and Brazil (14). In Europe, apart from UK (64), the Netherlands (31) and France (26) led the classification, followed by Sweden (18), Denmark (17), and France (26). Mediterranean countries are represented with 27 studies. A total of 76.4% did not include EE and 93.1% did not include PA. Only 23.6% of the studies contained both EI and EE. A large methodological diversity was perceived, with more than 14 different methods regarding EI, and more than 10 for EE. PA was only analyzed in scarce articles, and scarcely considered for interpretation of data and conclusions. Moreover, PA was often measured by subjective questionnaires. Dietary surveys show a large diversity regarding methodology, which makes comparability of studies difficult. EE and PA are missing in around 80% of studies or are not included in the interpretation of results. Conclusions regarding EI or diet adequacy in adults should not be taken without analyzing EE and PA.Spanish Nutrition Society (SEN

Efficacy of naloxegol on symptoms and quality of life related to opioid-induced constipation in patients with cancer: a 3-month follow-up analysis

Objectives: Opioid-induced constipation (OIC) can affect up to 63% of all patients with cancer. The objectives of this study were to assess quality of life as well as efficacy and safety of naloxegol, in patients with cancer with OIC. Methods: An observational study was made of a cohort of patients with cancer and with OIC exhibiting an inadequate response to laxatives and treated with naloxegol. The sample consisted of adult outpatients with a Karnofsky performance status score ≥50. The Patient Assessment of Constipation Quality of Life Questionnaire (PAC-QOL) and the Patient Assessment of Constipation Symptoms (PAC-SYM) were applied for 3 months. Results: A total of 126 patients (58.2% males) with a mean age of 61.3 years (range 34-89) were included. Clinically relevant improvements (>0.5 points) were recorded in the PAC-QOL and PAC-SYM questionnaires (p<0.0001) from 15 days of treatment. The number of days a week with complete spontaneous bowel movements increased significantly (p<0.0001) from 2.4 to 4.6 on day 15, 4.7 after 1 month and 5 after 3 months. Pain control significantly improved (p<0.0001) during follow-up. A total of 13.5% of the patients (17/126) presented some gastrointestinal adverse reaction, mostly of mild (62.5%) or moderate intensity (25%). Conclusions: Clinically relevant improvements in OIC-related quality of life, number of bowel movements and constipation-related symptoms were recorded as early as after 15 days of treatment with naloxegol in patients with cancer and OIC, with a good safety profile

Management of acute diverticulitis with pericolic free gas (ADIFAS). an international multicenter observational study

Background: There are no specific recommendations regarding the optimal management of this group of patients. The World Society of Emergency Surgery suggested a nonoperative strategy with antibiotic therapy, but this was a weak recommendation. This study aims to identify the optimal management of patients with acute diverticulitis (AD) presenting with pericolic free air with or without pericolic fluid. Methods: A multicenter, prospective, international study of patients diagnosed with AD and pericolic-free air with or without pericolic free fluid at a computed tomography (CT) scan between May 2020 and June 2021 was included. Patients were excluded if they had intra-abdominal distant free air, an abscess, generalized peritonitis, or less than a 1-year follow-up. The primary outcome was the rate of failure of nonoperative management within the index admission. Secondary outcomes included the rate of failure of nonoperative management within the first year and risk factors for failure. Results: A total of 810 patients were recruited across 69 European and South American centers; 744 patients (92%) were treated nonoperatively, and 66 (8%) underwent immediate surgery. Baseline characteristics were similar between groups. Hinchey II-IV on diagnostic imaging was the only independent risk factor for surgical intervention during index admission (odds ratios: 12.5, 95% CI: 2.4-64, P =0.003). Among patients treated nonoperatively, at index admission, 697 (94%) patients were discharged without any complications, 35 (4.7%) required emergency surgery, and 12 (1.6%) percutaneous drainage. Free pericolic fluid on CT scan was associated with a higher risk of failure of nonoperative management (odds ratios: 4.9, 95% CI: 1.2-19.9, P =0.023), with 88% of success compared to 96% without free fluid ( P &lt;0.001). The rate of treatment failure with nonoperative management during the first year of follow-up was 16.5%. Conclusion: Patients with AD presenting with pericolic free gas can be successfully managed nonoperatively in the vast majority of cases. Patients with both free pericolic gas and free pericolic fluid on a CT scan are at a higher risk of failing nonoperative management and require closer observation
