SYSTEMATICS OF GROUNDWATER OLIGOCHAETES (ANNELIDA, CLITELLATA) IN KARSTIC AREAS OF THE CANTABRIAN REGION/ ERREGIO KANTAURIARREKO EREMU KARSTIKOETAN DAUDEN LURPEKO OLIGOKETO (ANNELIDA, CLITELLATA) URT

This thesis deals with the oligochaete taxa (Annelida, Clitellata) from several karst units in the Cantabrian region, northern Iberian Peninsula. Groundwater oligochaetes are still poorly known fauna and the area seems to be a promising hotspot for groundwater taxa. Metodology is based on both morphological and molecular analyses. More than 7,000 specimens were collected from five karst units and >60 taxa were identified. Stygobiont oligochaete fauna in the northern Iberian Peninsula is diverse and mostly endemic (range areas <300 km). Three new stygogiont oligochaete species are described: Gianius navarroi Rodriguez & Achurra, 2010, Isochaetides gianii Rodriguez & Achurra, 2010 and Troglodrilus jugeti Achurra et al., 2012; and another four new taxa will be described in the near future. Taxonomic remarks on Lophochaeta ignota Stolc, 1886 and Troglodrilus galarzai (Giani & Rodriguez, 1988) are provided. The controversial separation of L. ignota and Heterochaeta costata Claparède, 1863 from Tubifex Lamarck, 1816 is corroborated by mitochondrial molecular data. Following the DNA barcoding method, individuals of the stygoxene species Stylodrilus heringianus Claparède, 1862 from different geographic areas are shown to represent a single metapopulation. The first phylogenetic analysis of the subfamily Tubificinae based on molecular data is attemped, which although incompletely resolved, evidences for the first time a close relationship between a stygobiont oligochaete (Troglodrilus Juget et al. 2006) and an estuarine especies (Heterochaeta costata Claparéde, 1863). A marine ancestor is hypothesised for Troglodrilus. Finally, Ereñozar karst unit (Biscay) is suggested to be a hotspot for groundwater oligochaetes (11 stygobiont taxa, of which 4 are endemic to the karst unit) and several biodiversity indices (Species richness, Rarity, Vulnerability and Complementarity) are shown to be useful tools for conservation management of groundwater habitats in that karst area.

Academic spin-offs incubation strategies: the case of the Andalusian region

[EN] The objective of this paper is to analyze the incubation strategies developed in the universities of Andalusia, a relatively low-income region of Spain, to promote the creation of university spin-offs. These strategies are also compared to the incubation models noted in the literature. The performance of the university spin-offs created and its relation to the incubation strategies developed by the university are also analysed. The analysis is based on data from a survey of nine public universities that carry out strategies for the promotion of university spin-offs. The result of the analysis shows that university spin-off incubation strategies in Andalusia present specific characteristics not covered by certain models that are well-known in the literature on innovation. Then, a new stage in the process of the university spin-off incubation is proposed. We consider it to be a pre-strategic stage to the academic spin-off incubation strategies. The analysis also finds certain environmental factors associated to those spin-offs promoted by Andalusian universities that achieve the highest level of performance. This result suggests that previous to making any decision involving investment into developing incubation strategies, universities should gauge whether they have sufficient resources and the possibilities of connecting with a Technology Park.

Uso pertinente del collarín cervical en el paciente traumático: una revisión sistemática.

Introducción y objetivo: El collarín cervical es un dispositivo que tiene como objetivo disminuir el movimiento del cuello para evitar lesiones secundarias en el manejo del paciente traumático en el ámbito prehospitalario. Mediante la realización de esta revisión sistemática se ha pretendido evaluar si la colocación del collarín cervical disminuye la movilidad del cuello en el paciente traumático, así como determinar si puede producir o evitar lesiones durante su manejo. Metodología: Revisión sistemática en base a las disposiciones PRISMA. Se elaboró un protocolo de búsqueda que se utilizó en cuatro bases de datos (Medline, Scopus, CINAHL y Web of Science) y se incluyeron ensayos clínicos y estudios observacionales publicados entre enero de 1995 y diciembre de 2014. Resultados: La revisión se realizó a partir de 10 ensayos clínicos no aleatorizados de modesta calidad metodológica: en 6 se utilizaron cadáveres con lesión cervical y en los otros 4 voluntarios sanos sin lesión cervical y un ensayo clínico aleatorizado de muestra pequeña realizado sobre cadáveres con lesión cervical. En los estudios realizados en pacientes sanos sin lesión cervical se observó que el collarín disminuía de forma significativa la movilidad del cuello frente a la no inmovilización. Por el contrario, en los estudios en los que participaban cadáveres con lesión cervical se determinó que el collarín cervical no disminuía la movilidad del cuello. Además en tres estudios se detectó un aumento de la separación intervertebral y en uno, un aumento de la presión venosa yugular. Conclusiones: Si bien la inmovilización cervical reduce la movilidad del cuello en pacientes sin lesión, este efecto no se produce en quienes presentan lesiones cervicales.

Long-Term Epidemiology of Streptococcus pneumoniae Serogroup 6 in a Region of Southern Europe with Special Reference to Serotype 6E

Streptococcus pneumoniae serotype 6E has recently been described, but its long-term epidemiology is not well known. From 1981-2013, 704 serogroup 6 clinical isolates were obtained in Gipuzkoa, Basque Country, Spain. All invasive and one in four non-invasive isolates were included. Overall, 75, 97, 51 and 45 serotypes 6A, 6B, 6C and 6E isolates, respectively, were detected. No serotype 6D isolates were identified. The prevalence of serotypes 6E and 6B, but not that of serotypes 6A and 6C, declined after the introduction of pneumococcal conjugate vaccines. Serotype 6E isolates showed the highest resistance rate. Most serotype 6E isolates were ST90.
