    Description: A global foraminiferal model was used to determine the seasonal imprint of planktonic foraminifera on the sedimentary record. The model provides monthly concentrations of five planktonic foraminiferal species used in paleoceanographic reconstructions including (sin. and dex.), , (white) and The temperature imprint in foraminiferal shells varies according to the season of calcification, and the sedimentary records retain this seasonal imprint. Proxy records for a species will therefore be weighted towards the values during the season of maximum production for that species. Our model prediction reveals that, in general, at high latitudes, close to the geographical limit of occurrence of each species, the signal is biased towards summer conditions. In contrast, at lower latitudes the signal is biased towards winter or annual mean conditions. Temperatures derived from (white) and are most suitable for estimating annual mean SST in tropical waters, between 20° N/S, while (white) when collected at mid-latitudes, near to 40° latitude, reflects mainly summer conditions. We carried out sensitivity experiments to study the response of planktonic foraminiferal seasonality to changes in temperature. We forced the model decreasing the temperature globally by 2 °C and 6 °C. In most of the regions, due to the cooling, the season of maximum production shifted to a warmer season. Thus, the annual species population recorded little change in the temperature. In tropical waters, where temperature seasonality is low, foraminiferal population recorded the entire temperature variation. These findings highlight the importance of considering changes in seasonality through time, specially for temperature reconstructions based on monospecific samples, such as those derived from planktonic foraminiferal isotopic and trace element composition.

    Description: Assessment and management of Atlantic bluefin tuna Thunnus thynnus populations is hindered by our lack of knowledge regarding trans-Atlantic movement and connectivity of eastern and western populations. Here, we evaluated migratory and homing behaviors of bluefin tuna in several regions of the North Atlantic Ocean and Mediterranean Sea using chemical tags ( delta super(13)C and delta super(18)O) in otoliths. Significant emigration of bluefin tuna from their place of origin was inferred from otolith delta super(13)C and delta super(18)O, with both eastern and western bluefin tuna commonly 'crossing the line' (45[degrees] W management boundary) in the Central North Atlantic Ocean and mixing with the other population. Several western migrants were also detected in Moroccan traps off the coast of Africa, indicating that trans-Atlantic movement occurs for members of the western population; however, the degree of mixing declined with proximity to the eastern spawning area (Mediterranean Sea). The origin of bluefin tuna collected at the entrance to the Strait of Gibraltar and from several regions within the Mediterranean Sea (Balearic Islands, Malta, and Sardinia) was essentially 100% eastern fish, demonstrating that natal homing is well developed by the eastern population, with western migrants rarely entering the Mediterranean Sea.

    Description: We used carbon and oxygen isotope ratios (δ 13 C and δ 18 O) in otoliths as a tool for identifying the nursery origin of Atlantic bluefin tuna ( Thunnus thynnus ) caught in the eastern North Atlantic Ocean (Bay of Biscay). Juvenile and adult bluefin tuna were collected over three consecutive years (2009—2011) using the regional bait boat fleet. Otolith δ 13 C and δ 18 O values of bluefin tuna were measured by mass spectrometry, and values were compared with a reference sample of yearling bluefin tuna from eastern (Mediterranean Sea) and western (Gulf of Mexico) nurseries to determine nursery origin. Maximum likelihood estimates based on otolith δ 13 C and δ 18 O values indicated that the overall contribution of western migrants to the Bay of Biscay fishery was 〈1% and varied over the years assessed. A small number of potential western migrants (2.7%) was detected in 2009, and most of these fish appear members of the abundant 2002 and 2003 year classes. In contrast, the Bay of Biscay fishery was composed exclusively (100%) of eastern origin bluefin tuna in 2010 and 2011, suggesting that this fishery is supported almost exclusively by the eastern spawning area but transatlantic western population may contribute to this fishery in a few years.

    Description: Aquest treball presenta els resultats d’un estudi en el qual s’analitzaren dos elements fonamentals en les relacions amb els iguals: la competència social i la conducta prosocial, en una mostra de 193 adolescents que cursen educació secundaria. Els resultats mostren com les sub-escales que mesuren la Conducta Prosocial exerceixen una influència significativa a les escales de Competència Social. Nivells alts de Conducta Prosocial es relacionen significativament de manera positiva amb la dimensió d’Habilitats Socials Apropiades de la Competència Social, mentre que nivells alts de Conducta Antisocial s’han relacionat positivament amb les escales d’Assertivitat Inapropiada, Orgull i Soledat. També s’ha constatat la significació positiva entre la sub-escala Conducta Antisocial i l’escala d’Assertivitat Inapropiada de la Competència Social.

    Description: El lupus eritematoso sistémico (LES) es una enfermedad de naturaleza autoinmune que afecta fundamentalmente a mujeres jóvenes y cuya mortalidad está aumentada para estos grupos de edad. Mediante el registro de altas hospitalarias en España y el análisis del conjunto mínimo básico de datos (CMBD) facilitado por el Ministerio de Sanidad se han analizado las altas hospitalarias en cuyos diagnósticos se incluyera el de LES. Estudio transversal descriptivo de todos los episodios codificados, según la CIE-9-MC, como LES de los pacientes hospitalizados durante 2005-2008 en todo el territorio español. Se identificaron un total de 5.464 episodios, de los cuales 1.855 (33%) tenían lupus como diagnóstico principal y 3.609 (66%) como secundario. Los pacientes del grupo LES principal son más jóvenes (41,56 ± 17,55 vs. 56,07 ± 19,01 años; p 〈 0,001), tienen un menor porcentaje de ingresos urgentes (62,5 vs. 84,8%; p 〈 0,001) y una comorbilidad menor, medida por el índice de Charlson (Charlson 〉 2; 18 vs. 35%; p 〈 0,001), así como una menor mortalidad (1,1 vs. 5,4%; p 〈 0,001). Los pacientes con LES que ingresan en los servicios de Medicina Interna en España suponen el 0,3% del total. Se identifican 2 grupos de pacientes, aquellos más jóvenes, con menor comorbilidad en proceso de diagnóstico y tratamiento inicial de la enfermedad y una segunda población de pacientes de más edad, con mayor comorbilidad y cuyos motivos de ingreso están relacionados con las infecciones y las complicaciones cardiovasculares. La mortalidad en este grupo es superior. Systemic lupus erythematosus (SLE) is an autoimmune disease that mainly affects young women and whose mortality is increasing for this age group. We used the national registry of Hospital discharges in Spain based on the study of the Minimum Basic Data Set (MBDS) to analyze hospital discharges of patients whose diagnosis included that of LES. A cross-sectional, descriptive study was performed of all episodes coded as having LES using ICD-9-MC coding system of the patients hospitalized within the period 2005-2008. A total of 5,464 episodes were identified, 1,855 (33%) as main diagnosis and 3,609 (66%) as secondary diagnosis. Patients having LES the main diagnosis were younger (41.56±17.55 vs 56.07±19.01 years; 〈.001), had fewer elective admittances (62.5 vs 84.8%; 〈.001), lower comorbidity as measured by the Charlson's index (Charlson 〉2; 18 vs 35%; 〈.001) and lower mortality (1.1 vs 5.4%; 〈.001). Patients admitted to internal medicine departments in Spain with a diagnosis of LES accounts for 0.3% of the total. Two different groups of patients are identified. The first group was younger, had lower comorbidity and were in the early phases of diagnosis and/or treatment. The second group was more numerous, older, with a higher comorbidity, with admittances frequently related to infections or cardiovascular complications and higher mortality rate.

    Description: Planktonic foraminifera preserved in marine sediments archive the physical and chemical conditions under which they built their shells. To interpret the paleoceanographic information contained in fossil foraminifera, the recorded proxy signals have to be attributed to the habitat and life cycle characteristics of individual species. Much of our knowledge on habitat depth is based on indirect methods, which reconstruct the depth at which the largest portion of the shell has been calcified. However, habitat depth can be best studied by direct observations in stratified plankton nets. Here we present a synthesis of living planktonic foraminifera abundance data in vertically resolved plankton net hauls taken in the eastern North Atlantic during 12 oceanographic campaigns between 1995 and 2012. Live (cytoplasm-bearing) specimens were counted for each depth interval and the vertical habitat at each station was expressed as average living depth (ALD). This allows us to differentiate species showing an ALD consistently in the upper 100 m (e.g., Globigerinoides ruber white and pink), indicating a shallow habitat; species occurring from the surface to the subsurface (e.g., Globigerina bulloides, Globorotalia inflata, Globorotalia truncatulinoides); and species inhabiting the subsurface (e.g., Globorotalia scitula and Globorotalia hirsuta). For 17 species with variable ALD, we assessed whether their depth habitat at a given station could be predicted by mixed layer (ML) depth, temperature in the ML and chlorophyll a concentration in the ML. The influence of seasonal and lunar cycle on the depth habitat was also tested using periodic regression. In 11 out of the 17 tested species, ALD variation appears to have a predictable component. All of the tested parameters were significant in at least one case, with both seasonal and lunar cyclicity as well as the environmental parameters explaining up to 〉 50 % of the variance. Thus, G. truncatulinoides, G. hirsuta and G. scitula appear to descend in the water column towards the summer, whereas populations of Trilobatus sacculifer appear to descend in the water column towards the new moon. In all other species, properties of the mixed layer explained more of the observed variance than the periodic models. Chlorophyll a concentration seems least important for ALD, whilst shoaling of the habitat with deepening of the ML is observed most frequently. We observe both shoaling and deepening of species habitat with increasing temperature. Further, we observe that temperature and seawater density at the depth of the ALD were not equally variable among the studied species, and their variability showed no consistent relationship with depth habitat. According to our results, depth habitat of individual species changes in response to different environmental and ontogenetic factors and consequently planktonic foraminifera exhibit not only species-specific mean habitat depths but also species-specific changes in habitat depth.

    Description: This paper describes the operational protocol established in the southeastern Bay of Biscay (study area) for the sighting and tracking of Portuguese man-of-war. This action protocol combines sightings of Portuguese man-of-war at sea with hourly surface currents and winds obtained with the Regional Ocean Modeling System (ROMS) and the Weather Research and Forecasting model (WRF), respectively. These data are used in the Sediment, Oil spill and Fish Tracking model (SOFT) to estimate the drift of Portuguese man-of-war. Here we provide information on sightings of Portuguese man-of-war in the study area and show the most relevant results of the SOFT calibration obtained using trajectories from eight satellite pop-up tags for fish tracking. These tags have similar characteristics (such as weight and density) to the Portuguese man-of-war that reach the study area. In 2012 and 2013, there were a total of 48 sightings of Portuguese man-of-war, most of them located in the Zarautz beach area (Basque Country coast). The SOFT calibration shows that the tag drift is mainly controlled by the wind. With winds from the southern and western sectors (third quadrant), SOFT is able to reproduce the tag drift using surface current velocities estimated as ~1.8% of the WRF wind velocities. The SOFT simulations carried out using the ROMS current velocities (with or without the WRF wind velocities) do not improve the results.

    Description: El patrón de uso de fármacos antiepilépticos (FAE) durante el embarazo difiere entre países y está cambiando. Se desconoce en qué medida ello afecta a la población española. La eficacia de los nuevos fármacos en el control de las crisis es motivo de preocupación y puede haber cambiado a lo largo de los años debido a un mejor conocimiento de su uso durante el embarazo. Con el objetivo de analizar estos 2 aspectos reportamos los resultados del registro EURAP España durante un periodo de 12 años. Tras el consentimiento informado, las pacientes son incluidas en el registro y evaluadas al inicio del embarazo, al final del segundo y tercer trimestres, después del parto y al año del nacimiento. Para los objetivos de este estudio hemos analizado: FAE, tipo de epilepsia, frecuencia de crisis por trimestres y a lo largo del embarazo, porcentaje de pacientes libres de crisis, y frecuencia de malformaciones congénitas mayores. Hemos comparado estas variables en 2 periodos (junio de 2001-octubre de 2007) y (enero de 2008-mayo de 2015). Un total de 304 monoterapias del periodo antiguo se comparan con 127 del periodo nuevo. Observamos un ascenso del uso de levetiracetam (LEV) y un descenso del uso de carbamacepina (CBZ), fenitoína y fenobarbital; un leve descenso del uso de valproato (VPA), y un leve aumento de lamotrigina (LTG) y oxacarbamacepina (OXC). El tipo de epilepsia se mantiene estable para CBZ y VPA, pero cambia para LTG, con menos epilepsias generalizadas tratadas con este fármaco en el periodo nuevo. Ello no se asocia con un cambio significativo de la frecuencia de crisis, pero sí con un mejor control de las crisis en el tercer trimestre. LEV se asocia a niveles de control de crisis similares a los de CBZ y VPA y mejor que con LTG. De las pacientes tratadas con LEV, un 64% tenían una epilepsia generalizada. El patrón de uso de los diferentes FAE durante el embarazo está cambiando en España, con menos uso de CBZ, fenitoína y fenobarbital y un aumento del uso de LEV. El tipo de epilepsia también cambia, con un porcentaje inferior de pacientes tratadas con LTG para epilepsias generalizadas. LEV controla las crisis de manera similar a los fármacos clásicos y mejor que la LTG. The prescription pattern of antiepileptic drugs (AEDs) during pregnancy is changing but to what extent this is occurring in Spain remains unknown. The efficacy of newer drugs for controlling seizures is a key issue and may have changed over the years as doctors gained familiarity with these drugs during pregnancy. To assess these 2 topics, we report the results from the Spanish EURAP register gathered over a 12-year period. After signing informed consent forms, patients were included in the register and evaluated at onset of pregnancy, at the end of the second and third trimesters, after delivery, and one year after delivery. For the purposes of this study, we analysed AEDs, type of epilepsy, seizure frequency per trimester and throughout pregnancy, percentage of seizure-free pregnancies, and frequency of congenital malformations. We then compared data from 2 periods (June 2001-October 2007) and (January 2008-May 2015) We compared 304 monotherapies from the older period to 127 from the more recent one. There was a clear increase in the use of levetiracetam (LEV) with declining use of carbamazepine (CBZ), phenytoin, and phenobarbital; a slight decline in use of valproate (VPA), and a slight increase in the use of lamotrigine (LTG) and oxcarbazepine (OXC). Epilepsy types treated with CBZ and VPA remained unchanged, whereas fewer cases of generalised epilepsy were treated with LTG in the new period. This trend was not associated with significant changes in seizure frequency, but rather linked to better control over de novo seizures in the third trimester. LEV was similar to CBZ and VPA with regard to levels of seizure control, and more effective than LTG. Generalised epilepsy accounted for 64% of the cases treated with LEV. The prescription pattern of AEDs during pregnancy has changed in Spain, with diminishing use of CBZ, phenytoin, and phenobarbital. Changes also reflect the type of epilepsy, since there is less use of LTG for generalised epilepsy. LEV provides similar seizure control to that of the older AEDs, and it is more effective and better than LTG.
