It is insoluble in water and does not require mordant to fix the color; therefore, due to its nature it can be considered as a pigment or dye. The identification of indigo in cultural heritage is very difficult due to the complexity of its chemical formula and the changes that it can undergo in certain conservation and exposition conditions. For this reason, characterization of possible degradation, transformation, and reaction processes is essential for its identification. In this study, multispectral imaging has been used for the first time as noninvasive technique to characterize the aging state of indigo blue using samples aged in a controlled climate chamber under extreme conditions of humidity, temperature, and light. The technique has proven to be very promising for this application, together with classification techniques based on machine learning approaches.FEDER/Junta de Andalucia-Consejeria de Economia y Conocimiento A-HUM-164-UGR18Ministry of Economy and Competitiveness of Spain DPI2015-64571-RSpanish Ministry of Economy and CompetitivenessMinistry of Economy and CompetitivenessJunta de AndaluciaEuropean Commissio

Dietary exposure to parabens and body mass index in an adolescent Spanish population

This work was carried out in line with 'GP/EFSA/ENCO/380 2018/03/G04: OBEMIRISK: Knowledge platform for assessing the risk of Bisphenols on gut microbiota and its role in obesogenic phenotype: looking for biomarkers'. This research was also funded by Plan Estatal de I + D + I 2013-2016 and co-funded by FEDER-ISCIII PI17/01758, FEDER-Consejeria de Salud y Familias, Junta de Andalucia PE-0250-2019, FEDER/Junta de Andalucia-Consejeria de Transformacion Economica, Industria, Conocimiento y Universidades/Proyecto P18-RT-4247. All individuals participating in this research signed an informed consent form and the study protocol was approved by the Ethics Com-mittee of the University of Granada.Parabens are alkyl esters of p-hydroxybenzoic acid which are extensively used in cosmetics, pharmaceuticals and foodstuffs due to their antimicrobial properties. The most commonly used parabens are methyl-(MeP), ethyl- (EtP), propyl-(PrP) and butyl-(BuP) paraben. Most human exposure to parabens is achieved through the consumption of food or pharmaceutical products and the use of personal care products. However, studies on dietary parabens exposure and the associated factors are very scarce. The main aim of the present study was to explore factors associated with dietary exposure to parabens in Spanish adolescents according to gender. Dietary data and anthropometric measures were collected from 585 adolescents (53.4% boys) aged 12–16 years. Parabens exposure through diet was assessed using a food frequency questionnaire with food products providing more than 95% of energy and macronutrient intake being included in analysis. Stepwise regression was used to identify the foods that most contributed to parabens intake. Logistic regression was used to evaluate factors predicting higher dietary exposure to parabens. The main contributors to dietary MeP, EtP, PrP and BuP exposure in adolescent boys were eggs (41.9%), canned tuna (46.4%), bakery and baked goods products (57.3%) and pineapple (61.1%). In adolescent girls, the main contributors were apples and pears (35.3%), canned tuna (42.1%), bakery and baked goods products (55.1%) and olives (62.1%). Overweight/obese girls were more likely to belong to the highest tertile of overall parabens intake (odds ratio [OR]: 3.32; 95% confidence interval [95% CI]: 1.21–9.15) and MeP (OR: 3.05; 95% CI: 1.14–8.12) than those with a body mass index lower than 25 kg/m2. These findings suggest a positive association between dietary exposure to parabens and overweight/obesity in adolescent girls.Plan Estatal de I + D + I 2013-2016FEDER-ISCIII PI17/01758FEDER-Consejeria de Salud y FamiliasJunta de Andalucia PE-0250-2019FEDER/Junta de Andalucia-Consejeria de Transformacion Economica, Industria, Conocimiento y Universidades/Proyecto P18-RT-424

Cueva de los Torrejones revisited. New insights on the paleoecology of inland Iberia during the Late Pleistocene

34 p.The interior of the Iberian Peninsula has orographic conditions that make this territory especially vulnerable to Quaternary climate oscillations and which actually could have made it decisive for Paleolithic human populations at critical points. For this reason, the information provided by paleontological sites is important for reconstructing climatic and environmental conditions during the Late Pleistocene and understanding how they influenced the species that inhabited them, including humans. Nevertheless, the archaeo-paleontological record is scarce in central Iberia for the Late Pleistocene. A central Iberian site that is key to addressing this issue is Cueva de los Torrejones, which was discovered and excavated during the nineties. Clues indicating the presence of Neandertal populations near the cave site were announced during prior field excavations, including Neandertal remains, Middle Paleolithic artifacts, and evidence of anthropic exploitation of faunal resources at the site. Here we report the new results from the recent excavations and research, including detailed studies on stratigraphy, micromorphology, macro and microvertebrate paleontology, physical and molecular anthropology, taphonomy and zooarchaeology, and analysis of lithic and pottery remains. Our research has led to the detection of three Prehistoric chronologies recorded at the site. The oldest episode corresponds to between MIS 5 and MIS 4 in which the cave was used by carnivores. The second episode is represented by a faunal association dated to 30.0 ka cal BP and is indicative of cooler and more arid environmental conditions and, therefore, compatible with the worsening climate detected previously for MIS 3 in this area. The last episode corresponds to the Chalcolithic, directly dated to ~5000 cal BP in which humans used the cavity for funerary purposes. The DNA analysis of the human remain was assigned to mtDNA haplogroup K, which was originated in the Near East and reached western Europe through the Neolithic expansion. Human occupation during the Paleolithic has been ruled out, including Paleolithic human remains and any kind of anthropic intervention on the Hermann’s tortoise and leopard as was previously proposed at the site.European Research CouncilJunta de Comunidades de Castilla la ManchaMinisterio de Ciencia e InnovaciónCentro Nacional de Investigación sobre la Evolución Humana (CENIEH

Optimal surgical timing after post-infarction ventricular septal rupture

Background: Ventricular septal rupture (VSR) following acute myocardial infarction (AMI) is a dan-gerous condition. Surgical VSR closure is the definitive therapy, but there is controversy regarding the surgical timing and the bridging therapy between diagnosis and intervention. The objective of this study is to analyze the ideal time of surgical repair and to establish the contribution of mechanical circulatory support (MCS) devices on the prognosis. Methods: We designed an observational, retrospective, multicenter study, selecting all consecutive patients with post-AMI VSR between January 1, 2008 and December 31, 2018, with non-exclusion criteria. The main objective of this study was to analyze the optimal timing for surgical repair of post-AMI VSR. Second- ary endpoints were to determine which factors could influence mortality in the patients of the surgical group. Results: A total of 141 patients were included. We identified lower mortality rates with an odds ratio of 0.3 (0.1 & ndash;0.9) in patients operated on from day 4 compared with the surgical mortality in the first 24 hours after VSR diagnosis. The use of MCS was more frequent in patients treated with surgery, par- ticularly for intra-aortic balloon pump (IABP; 79.6% vs. 37.8%, p < 0.001), but also for veno-arterial extracorporeal membrane oxygenation (VA-ECMO; 18.2% vs. 6.4%, p = 0.134). Total mortality was 91.5% for conservative management and 52.3% with surgical repair (p < 0.001). Conclusions: In our study, we observed that the lowest mortality rates in patients with surgical repair of post-AMI VSR were observed in patients operated on from day 4 after diagnosis of VSR, compared to earlier interventions.

Spanish home enteral nutrition registry of the year 2014 and 2015 from the NADYA-SENPE Group

Objetivo: exponer los resultados del registro de nutrición enteral domiciliaria (NED) del año 2014 y 2015 del Grupo NADYA-SENPE. Métodos: se recopilaron los pacientes introducidos en el registro desde el 1 de enero al 31 de diciembre de 2014 y la mismas fechas de 2015, y se procedió al análisis descriptivo y analítico de los datos. Resultados: en el año 2014, se registraron 3.749 pacientes y en 2015, 4.202; la prevalencia fue de 80,58 pacientes/millón de habitantes en el año 2014 y de 90,51 en 2015. Por sexos, hubo un 49,9% de mujeres en 2014 y un 50,3% en 2015. La edad media fue de 73 años (IIQ 59-83) en ambos años. Finalizaron 684 episodios de NED en 2014 y 631 en 2015, la causa principal fue el fallecimiento en el 54,9% y 50,4% de los casos, respectivamente. Los portadores de sonda nasogástrica presentan una edad media superior a los pacientes con cualquier otra vía (p < 0,001). Se registraron 67 pacientes pediátricos en 2014 (56,7% niñas) y 77 en 2015 (55,8% niñas). La vía principal de administración fue la gastrostomía en el 52,0% de los casos de 2014 y sonda nasogástrica en el 50,8% de los casos de 2015. La causa principal de fi nalización de la nutrición fue el fallecimiento (57,1% en 2014 y 38,5% en 2015). Se observó que los niños más pequeños eran los que se alimentaban preferentemente por SNG (p 0,004 vs. 0,002).Tanto en pacientes pediátricos como en adultos el diagnóstico principal que motivó la necesidad de NED fue la enfermedad neurológica que cursa con afagia o disfagia severa. Conclusiones: se ha incrementado el número de pacientes del registro, así como el número de centros participantes y el número medio de pacientes comunicados por cada centro respecto a años anteriores, sin que se hayan modificado sustancialmente las características de los pacientes, salvo mayor duración de los episodiosObjective: To present the results of the Spanish home enteral nutrition (HEN) registry of the NADYA-SENPE group for the years 2014 and 2015. Methods: From January 1st 2014 to December 31st 2015 the HEN registry was recorded and afterwards a further descriptive and analytical analysis was done. Results: In 2014, 3749 patients were recorded, and 4202 in 2015; prevalence was 80.58 patients/one million inhabitants in Spain in 2014 and 90.51 in 2015. There were 49.9% females in 2014 and 50.3% in 2015. Median age was 73 years (IQI 59-83) in 2014 as well as in 2015. 684 episodes fi nished in 2014 and 631 in 2015, with death as the main cause, in 54.9% and 50.4%, respectively. The ones who were fed through nasogastric tube had a mean age higher than the ones fed by any other route (p-value < 0.001). Sisty-seven paediatric patients were recorded in 2014 (56.7% females) and 77 in 2015 (55.8% females). Median age at the beginning of HEN among children was 5 months in 2014 and 5 months in 2015. The main route of administration was gastrostomy, in 52.5% in 2014 and nasogastric tube in 50.8% in 2015. 7 episodes fi nished in 2014 and 13 in 2015, having death as the main cause (57.1% in 2014 and 38.5% in 2015). It was found that were younger children the ones who were mainly fed by nasogastric tubes (p-value 0.004 vs. 0.002). Among paediatric patients as well as adults, the main diagnosis leading to HEN was neurological disease which gives aphagia or severe dysphagia. Conclusions: There has been an increase in the number of patients in the registry as well as the participating centers and the number of patients per center, without any signifi cant change in the characteristics of the patients other than longer duration of the episode

Randomized Controlled Trial Assessing the Impact of Tacrolimus Versus Cyclosporine on the Incidence of Posttransplant Diabetes Mellitus

Despite the high incidence of posttransplant diabetes mellitus (PTDM) among high-risk recipients, no studies have investigated its prevention by immunosuppression optimization. We conducted an open-label, multicenter, randomized trial testing whether a tacrolimus-based immunosuppression and rapid steroid withdrawal (SW) within 1 week (Tac-SW) or cyclosporine A (CsA) with steroid minimization (SM) (CsA-SM), decreased the incidence of PTDM compared with tacrolimus with SM (Tac-SM). All arms received basiliximab and mycophenolate mofetil. High risk was defined by age >60 or >45 years plus metabolic criteria based on body mass index, triglycerides, and high-density lipoprotein-cholesterol levels. The primary endpoint was the incidence of PTDM after 12 months. The study comprised 128 de novo renal transplant recipients without pretransplant diabetes (Tac-SW: 44, Tac-SM: 42, CsA-SM: 42). The 1-year incidence of PTDM in each arm was 37.8% for Tac-SW, 25.7% for Tac-SM, and 9.7% for CsA-SM (relative risk [RR] Tac-SW vs. CsA-SM 3.9 [1.2-12.4; P = 0.01]; RR Tac-SM vs. CsA-SM 2.7 [0.8-8.9; P = 0.1]). Antidiabetic therapy was required less commonly in the CsA-SM arm (P = 0.06); however, acute rejection rate was higher in CsA-SM arm (Tac-SW 11.4%, Tac-SM 4.8%, and CsA-SM 21.4% of patients; cumulative incidence P = 0.04). Graft and patient survival, and graft function were similar among arms. In high-risk patients, tacrolimus-based immunosuppression with SM provides the best balance between PTDM and acute rejection incidence
