Erratum to “New palynological data from the Late Pleistocene glacial refugium of South-West Iberia: The case of Doñana” [Review of Palaeobotany and Palynology (2021) PALBO 104431]
Review of Palaeobotany and Palynology, Volume 296, January 2022, Pages 104566The Doñana area in southern Iberia is one of the most renowned protected areas of Europe, mostly due to the diversity and value of its wetland ecosystems. The large biogeographical significance of this territory and the outstanding availability of sedimentary archives have made this region a hotspot of paleobotanical research in the Iberian Peninsula. Specifically, the organic deposits on El Asperillo Cliff have been studied during the past few decades from the geomorphological and paleobotanical (pollen, macrofossils) points of view. However, large uncertainties remain concerning the chronology of certain sections of the exposed profile and the paleobotanical potential of this site has not been fully exploited yet. In this study, we revisited El Asperillo with the aims of completing the paleobotanical record and refining the chronology of this site. The age of the studied deposits ranges from ca. 22,000 to 30,900 cal. yr BP according to the radiocarbon dates obtained, thus embracing the particularly cold and dry Heinrich Event 2 and the Last Glacial Maximum. Our palynological results allow inferring the presence of a coastal marshland system. Additionally, the new pollen records highlight the relevance and diversity of pines (Pinus nigra-sylvestris type, P. pinaster, P. halepensis-pinea type) in the Late Pleistocene landscape of Doñana, reinforcing the native status of pines. Last but not least, the results stress the persistence of a highly diverse woody flora in Doñana during the harshest periods of the last glacial cycle, highlighting the importance of this enclave in postglacial vegetation recolonization of the Iberian Peninsula.The development of this work was supported by Projects FEDER/Ministry of Science and Innovation, Agencia Estatal de Investigación CGL-BOS2015-68604-P and PID2019-1049449GB-I00), 261-2011 Organismo Autónomo de Parques Nacionales and Fundación Séneca grant 20788/PI/18Peer reviewe

Casuística de códigos ictus atendidos por 061 Aragón en el período 2010-2016. Factores que influyen en los tiempos de respuesta y de acceso a la fibrinólisis.
Objetivo. Estudiar los tiempos de respuesta en la atención al código ictus por unidades asistenciales del 061 ARAGÓN, analizando los factores implicados y su relación con el acceso al tratamiento fibrinolítico en la fase hiperaguda.
Pacientes y métodos. Estudio descriptivo transversal sobre la asistencia extrahospitalaria a partir del registro de casos atendidos por unidades asistenciales del 061 ARAGÓN a pacientes con código ictus durante el período 2010-2016.
Resultados. Se recogieron 1.743 pacientes con código ictus (54,6%, varones), con una edad media de 72,83 ± 13,1 años. El número de ictus atendidos en 2015 y 2016 (372 y 366, respectivamente) fue mayor que la media de 201 ictus anuales en el resto de los años. El 27,2% de los pacientes fueron atendidos entre las 08:00 y las 11:59 h, intervalo horario con mayor frecuentación. Respecto al tiempo que se tardó en atender al paciente, la media fue de 71,93 ± 33,64 minutos, con mayor tiempo de respuesta en Teruel. Cuando se analizó la influencia del intervalo horario sobre el porcentaje de casos tratados con fibrinólisis, se observó una mayor tasa de fibrinólisis cuando se activó entre las 12:00 y las 15:59 h (28,1%).
Conclusión. En el 55,3% de los pacientes, el tiempo de respuesta del 061 fue mayor de 60 minutos, pero este tiempo no se vio condicionado por la hora de activación. Sin embargo, sí había diferencias en el porcentaje de casos de fibrinólisis en los diferentes intervalos horarios, lo que sugiere que factores distintos al tiempo de respuesta del 061 influyen en la indicación del tratamiento fibrinolítico
