Life in the spray zone - overlooked diversity in West African torrent-frogs (Anura, Odontobatrachidae, Odontobatrachus)
West African torrent-frogs of the genus Odontobatrachus currently belong to a single species: Odontobatrachus natator (Boulenger, 1905). Recently, molecular results and biogeographic separation led to the recognition of five Operational Taxonomic Units (OTUs) thus identifying a species-complex. Based on these insights, morphological analyses on more than 150 adult specimens, covering the entire distribution of the family and all OTUs, were carried out. Despite strong morphological congruence, combinations of morphological characters made the differentiation of OTUs successful and allowed the recognition of five distinct species: Odontobatrachus natator, and four species new to science: Odontobatrachus arndti sp. n., O. fouta sp. n., O. smithi sp. n. and O. ziama sp. n. All species occur in parapatry: Odontobatrachus natator is known from western Guinea to eastern Liberia, O. ziama sp. n. from eastern Guinea, O. smithi sp. n. and O. fouta sp. n. from western Guinea, O. arndti sp. n. from the border triangle Guinea-Liberia-Cote d'Ivoire. In addition, for the first time the advertisement call of a West African torrent-frog (O. arndti sp. n.) is described

Guía Clínica Española del Acceso Vascular para Hemodiálisis
El acceso vascular para hemodiálisis es esencial para el enfermo renal tanto por su
morbimortalidad asociada como por su repercusión en la calidad de vida. El proceso que
va desde la creación y mantenimiento del acceso vascular hasta el tratamiento de sus
complicaciones constituye un reto para la toma de decisiones debido a la complejidad de la
patología existente y a la diversidad de especialidades involucradas. Con el fin de conseguir
un abordaje consensuado, el Grupo Español Multidisciplinar del Acceso Vascular (GEMAV),
que incluye expertos de las cinco sociedades científicas implicadas (nefrología [S.E.N.], cirugía
vascular [SEACV], radiología vascular e intervencionista [SERAM-SERVEI], enfermedades
infecciosas [SEIMC] y enfermería nefrológica [SEDEN]), con el soporte metodológico del Centro
Cochrane Iberoamericano, ha realizado una actualización de la Guía del Acceso Vascular
para Hemodiálisis publicada en 2005. Esta guía mantiene una estructura similar, revisando
la evidencia sin renunciar a la vertiente docente, pero se aportan como novedades, por un
lado, la metodología en su elaboración, siguiendo las directrices del sistema GRADE con
el objetivo de traducir esta revisión sistemática de la evidencia en recomendaciones que
faciliten la toma de decisiones en la práctica clínica habitual y, por otro, el establecimiento
de indicadores de calidad que permitan monitorizar la calidad asistencial.Vascular access for haemodialysis is key in renal patients both due to its associated morbidity
and mortality and due to its impact on quality of life. The process, from the creation and
maintenance of vascular access to the treatment of its complications, represents a challenge
when it comes to decision-making, due to the complexity of the existing disease and the
diversity of the specialities involved. With a view to finding a common approach, the Spanish
Multidisciplinary Group on Vascular Access (GEMAV), which includes experts from the five
scientific societies involved (nephrology [S.E.N.], vascular surgery [SEACV], vascular and
interventional radiology [SERAM-SERVEI], infectious diseases [SEIMC] and nephrology nursing
[SEDEN]), along with the methodological support of the Cochrane Center, has updated the
Guidelines on Vascular Access for Haemodialysis, published in 2005. These guidelines maintain
a similar structure, in that they review the evidence without compromising the educational
aspects. However, on one hand, they provide an update to methodology development following
the guidelines of the GRADE system in order to translate this systematic review of evidence
into recommendations that facilitate decision-making in routine clinical practice, and, on
the other hand, the guidelines establish quality indicators which make it possible to monitor
the quality of healthcare
