    Estudio de la flora vascular y la micobiota micorrícica en quemados truferos de Navarra (España)
    (Comunità Montana dei Monti Martani Serano e Subasio, 2010) Cavero-Remon, R.Y. (Rita Yolanda); Gonzalez-Armada, M. (MB); Miguel-Velasco, A.M. (Ana Maria) de
    In spite of the continuous advances in trufficulture there are still many questions about truffle growing, hence the big importance of studying the characteristics of the environment in which it best develops. In this study we have analysed the main ecological characteristics of the vascular flora growing in 24 holm oak brûles. This flora is special, very influenced by the alelopatic substances produced by the mycelium of the fungus, modifying the composition and the characteristics of the flora. As a result, plants grow smaller and with a lower covering. Sometimes they even present changes in their life-cycle. Therophytes typical of disturbed areas are dominant in plantations. Xerophile plants are also common. Besides, the species found in truffiers are proper of shaken, removed and generally sunny, dry and stony places, and many of them weeds. This corroborates the fact that the brûle is a very disturbed environment, both by fungus mycelium as by human intervention. On the other hand, monitoring the mycorrhizae is very important in truffle growing since it allows us to know if the plantations are properly developing or if truffle mycorrhizae have been replaced by other competing fungi. That is why we have carried out a below-ground study of the mycorrhizae appearing in the roots of the same holm-oaks, to check the presence of truffle mycorrhizae and to know if other mycorrhizal fungi are colonizing the roots.

    Actividad trufícola navarra. Cuestiones sin respuesta
    (Comunità Montana dei Monti Martani Serano e Subasio, 2010) Saez, R. (Raimundo); Miguel-Velasco, A.M. (Ana Maria) de
    In Navarra, first plantations were carried out in 1989. The ignorance about truffle and trufficulture was total. Almost everything about truffle was unknown, almost even its existence, but as a consequence of the permanent search for new crops that contribute to diversify and improve agricultural productions of the region, it was decided with great interest to carry out the first plantations, and find information, mainly in France and Italy. Twenty years have passed. Technical and scientific advances have taken place but there are still many doubts. The expectations raised at first have not been reached in many cases. In spite of that, trufficulture is a reality, that covers important areas in those zones suitable for truffle growing, both in Navarra and in Spain, and it is still increasing. In Navarra, with the experience acquired, a few points can be made: • Mycorrhized plant production has evolve positively in Spain, which guarantees one of the most important factors in the reasonable trufficulture, together with land selection, climate or cultivation techniques. • The soil: lands selected for new plantations suit truffle needs. They are bigger plots, which is favourable to the correct management of plantation. • Irrigation: in new trufficulture the irrigation studies and practice have become very necessary. The experimentation in this subject is necessary to cover crop needs. • Spreading and training: promoting trufficulture as a diversification alternative in rural areas has been the aim reached through courses, trips, conferences, festivals, commercial exhibitions, competitions…, which has culminated with the creation of the first Truffle Museum in Spain.

    Brand building: the case of collaborationbBetween Javier Carvajal and Loewe
    (Palgrave MacMillan, 2019) Cantista, I. (Isabel); Josa-Martínez, M.E. (María Eugenia); Villanueva-Fernández, M. (María)
    Through the study of the collaboration between the Architect Javier Carvajal and the Spanish luxury fashion brand Loewe, we seek to demonstrate how the relationship between architecture and fashion can become a genuine dialogue, where mutual learning and influencing occurs, which ultimately contributes to the affirmation of the values of the brand with an impact on its image and brand equity, what offers a new approach between architecture and fashion within the scope of brand management. We do that, through the analysis of the Loewe Serrano Street store, the flagship store where started the Loewe’s image renewal based on the modernisation of tradition as a luxury strategy.

    PodcastSpain: análisis de los podcasts de audio más populares en iTunes de España
    (Asociación Española de Investigación de la Comunicación (AE-IC), 2018-07) Antunes, M.J. (Maria João); Salaverría-Aliaga, R. (Ramón)
    Esta investigación analiza los podcasts de audio más populares en España, con el objetivo de identificar sus patrones y modelos de referencia. El análisis se basa en una muestra de los 200 servicios de podcast de audio más populares en iTunes en España, en dos fechas distintas de 2017. En el análisis fueron considerados los programas específicamente creados para internet y distribuidos mediante podcasting. Esta muestra fue analizada de acuerdo con varios parámetros. El análisis de los datos permite confirmar que la producción de podcasts en España presenta notable grado de madurez, traducida en una significativa variedad en la oferta. En el caso de los podcasts producidos por grupos mediáticos, como alternativa a la producción distribuida mediante emisiones hertzianas, se observa una apuesta especial por los productos de ficción y entretenimiento, que se benefician notablemente de las estructura de producción y recursos financieros de las corporaciones que los producen. Por su parte, entre los podcasts producidos o integrados en redes independientes de podcasting, destaca la popularidad alcanzada por programas dedicados a tecnología, en particular al análisis de novedades tecnológicas. Se advierte, con todo, una débil apuesta por parte de estas redes en la divulgación web y en las redes sociales de sus contenidos. Entre los podcasts creados por usuarios (User Created Content, UCC), se constata que existe una significativa producción de podcasts altruistas, sobre todo dedicados a la divulgación científica. Para mantener la continuidad de este tipo de programas es habitual recurrir a un modelo de financiación basado en el crowdfunding. Su grado de presencia en sitios web y redes sociales tiende a ser, asimismo, elevado. Se constata, por último, una diminuta participación de las mujeres en la creación de todos los tipos de podcasts analizados.

    “¿Por qué me has tirado, Amor, / todo el metal de tu aljaba?”: El episodio de las bodas de Camacho en El amor hace milagros (1784), de Pedro Benito Gómez Labrador
    (University of California, 2012) Mata-Induráin, C. (Carlos)
    Existen, en el siglo XVIII, numerosas recreaciones dramáticas del Quijote y, de entre todas ellas, son bastantes las que toman como punto de partida el episodio de las bodas de Camacho.2 Así, tenemos Las bodas de Camacho, comedia nueva jocoseria en dos actos (de hacia 1770, conservada en la BNE, Ms. 15.918), de Antonio Valladares de Sotomayor; Las bodas de Camacho, zarzuela nueva española, de Leandro Ontala y Maqueda (1776, BNE, Ms. 14.608); Las bodas de Camacho el rico (1784), de Juan Meléndez Valdés, la más famosa de todas; Las bodas de Camacho. Comedia pastoral en cinco actos (BNE, Ms. 14.071), además de la pieza que ahora me ocupa: El amor hace milagros (también de ese mismo año 1784), de Pedro Benito Gómez Labrador. Como ha señalado la crítica, el tema del matrimonio de los jóvenes, y más concretamente el debate sobre si debían ser los padres o los propios hijos quienes habían de decidir a la hora de tomar estado, era una cuestión de enorme actualidad, un debate candente en la sociedad dieciochesca. Es ahí donde hay que buscar, sin duda, la razón de esa preferencia de los dramaturgos por este episodio concreto del Quijote a la hora de abordar recreaciones de la obra cervantina.

    Background Colon capsule endoscopy (CCE) represents a noninvasive technology that allows visualization of the colon without requiring sedation and air insufflation. A second-generation colon capsule endoscopy system (PillCam Colon 2) (CCE-2) was developed to increase sensitivity for colorectal polyp detection compared with the first-generation system. Objective To assess the feasibility, accuracy, and safety of CCE-2 in a head-to-head comparison with colonoscopy. Design and Setting Prospective, multicenter trial including 8 European sites. Patients This study involved 117 patients (mean age 60 years). Data from 109 patients were analyzed. Intervention CCE-2 was prospectively compared with conventional colonoscopy as the criterion standard for the detection of colorectal polyps that are ≥6 mm or masses in a cohort of patients at average or increased risk of colorectal neoplasia. Colonoscopy was independently performed within 10 hours after capsule ingestion or on the next day. Main Outcome Measurements CCE-2 sensitivity and specificity for detecting patients with polyps ≥6 mm and ≥10 mm were assessed. Capsule-positive but colonoscopy-negative cases were counted as false positive. Capsule excretion rate, level of bowel preparation, and rate of adverse events also were assessed. Results Per-patient CCE-2 sensitivity for polyps ≥6 mm and ≥10 mm was 84% and 88%, with specificities of 64% and 95%, respectively. All 3 invasive carcinomas were detected by CCE-2. The capsule excretion rate was 88% within 10 hours. Overall colon cleanliness for CCE-2 was adequate in 81% of patients. Limitations Not unblinding the CCE-2 results at colonoscopy; heterogenous patient population; nonconsecutive patients. Conclusion In this European, multicenter study, CCE-2 appeared to have a high sensitivity for the detection of clinically relevant polypoid lesions, and it might be considered an adequate tool for colorectal imaging.

    Split-dose sodium picosulfate–magnesium citrate colonoscopy preparation achieves lower residual gastric volume with higher cleansing effectiveness than a previous-day regimen
    (2016) Carretero, C. (Cristina); Herraiz, M. T. (María Teresa); Riva, S. (Susana) de la; Angós, R. (Ramón); Lopez-Olaondo, L. (Luis); Muñoz-Navas, M. (Miguel); Alzina, A. (Alejandra); Prieto-Frías, C. (Cesár); Betes, M.T. (María Teresa)
    Background and Aims It is known that sodium picosulfate–magnesium citrate (SPMC) bowel preparations are effective, well tolerated and safe, and that split-dosing is more effective for colon cleansing than previous-day regimens. Anesthetic guidelines consider that residual gastric fluid is independent of clear liquid fasting times. However, reluctance to use split-dosing persists. This may be due to limited data on residual gastric fluid volumes (RGFVs) and split-dosing bowel preparations, and that these may not be perceived as standard clear liquids. Furthermore, no studies are available on RGFV/residual gastric fluid pH (RGFpH) and SPMC. We aimed to evaluate the cleansing effectiveness and the RGFV/RGFpH achieved after an SPMC split-dosing regimen compared with a SPMC previous-day regimen. Methods This was a single-center observational study. A total of 328 outpatients scheduled for simultaneous EGD and colonoscopy and following a split-dosing or previous-day regimen of SPMC were included. We prospectively measured colon cleanliness by using the Ottawa Bowel Preparation Scale, RGFV, and RGFpH. Results Ottawa Bowel Preparation Scale scores for overall, right, mid-colon, and colon fluid were significantly better in the split-dosing group. In the split-dosing group, the 3- to 4-hour fasting time consistently achieved the best cleansing quality. RGFV was significantly lower in the split-dosing group (11.09 vs 18.62, P < .001). No significant differences in RGFpH were detected. Conclusions Split-dosing SPMC provides higher colon cleansing quality with lower RGFVs than previous-day SPMC regimens. SPMC in split-dosing acts exactly as a standard clear liquid acts, and thus anesthetic guidelines on this issue may be applied with no concerns.

(Federica); Pérez-Cuadrado-Robles, E. (Enrique); López-Higueras, A. (Antonio)
    METHODS This is a multi-centre, observational, analytical, retrospective study. A total of 163 patients with suspicion of celiac disease (CD) (mean age = 46.4 ± 17.3 years, 68.1% women) who underwent CE from 2003 to 2015 were included. Patients were divided into four groups: seronegative CD with atrophy (Group-I, n = 19), seropositive CD without atrophy (Group-II, n = 39), contraindication to gastroscopy (Group-III, n = 6), seronegative CD without atrophy, but with a compatible context (Group-IV, n = 99). DY, TI and the safety of CE were analysed. RESULTS The overall DY was 54% and the final diagnosis was villous atrophy (n = 65, 39.9%), complicated CD (n = 12, 7.4%) and other enteropathies (n = 11, 6.8%; 8 Crohn’s). DY for groups I to IV was 73.7%, 69.2%, 50% and 44.4%, respectively. Atrophy was located in duodenum in 24 cases (36.9%), diffuse in 19 (29.2%), jejunal in 11 (16.9%), and patchy in 10 cases (15.4%). Factors associated with a greater DY were positive serology (68.3% vs 49.2%, P = 0.034) and older age (P = 0.008). On the other hand, neither sex nor clinical presentation, family background, positive histology or HLA status were associated with DY. CE results changed the therapeutic approach in 71.8% of the cases. Atrophy was associated with a greater TI (92.3% vs 45.3%, P < 0.001) and 81.9% of the patients responded to diet. There was one case of capsule retention (0.6%). Agreement between CE findings and subsequent histology was 100% for diagnosing normal/other conditions, 70% for suspected CD and 50% for complicated CD. CONCLUSION CE has a high DY in cases of suspicion of CD and it leads to changes in the clinical course of the disease. CE is safe procedure with a high degree of concordance with histology and it helps in the differential diagnosis of CD.

    EchoBrush may be superior to standard EUS-guided FNA in the evaluation of cystic lesions of the pancreas
    (2011) Lozano, M.D. (María Dolores); Álvarez-Cienfuegos, J. (Javier); Subtil, J.C. (José Carlos); Echeveste, J.I. (José I.); Labiano, T. (Tania); Idoate, M.A. (Miguel Ángel); Prieto-Frías, C. (Cesár); Betes, M.T. (María Teresa)
    BACKGROUND: Cystic lesions of the pancreas are being detected with increasing frequency. Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) is one of the most precise methods of diagnosis but still has limited accuracy. A new, through-the-needle cytologic brush system (EchoBrush; Cook Medical, Bloomington, Ind) has been approved for use during EUS evaluation of cystic pancreatic lesions. METHODS: Data from 127 EUS-FNAs of pancreatic cystic lesions were analyzed to compare the cytologic yield of EchoBrush with conventional EUS-FNA. An attending cytopathologist was present on site to assess specimen adequacy in all the cases. Diagnostic yields of both procedures, as well as related adverse events, were recorded. Statistical analysis was performed with the SPSS 15.0 version software (SPSS, Chicago, Ill). RESULTS: A total of 127 cystic lesions of the pancreas from 120 patients (42 men and 78 women, mean age of 62.17 ± 12.17 years) were included in the study. Mean size of lesions was 23.58 ± 21.69 mm. Adequacy of the samples and diagnostic yield were higher using EchoBrush. In 80 (63 %) cases, conventional EUS-FNA was performed, whereas in 47 (37%), we used EchoBrush. Diagnostic material was obtained in 85.1% (40 of 47) of cases using EchoBrush and in 66.3% (53 of 80) with conventional EUS-FNA. (P < .05). There were very few clinically relevant complications related to EUS-FNA and EUS-EchoBrush techniques. CONCLUSIONS: This study suggests that cytological specimens from pancreatic cystic lesions obtained using EchoBrush at the time of EUS are superior to conventional EUS-FNA mainly because of the higher yield of epithelial cells. Larger studies are needed to compare both methods. Cancer (Cancer Cytopathol) 2011. © 2011 American Cancer Society.
