Preliminary data on cold-water corals and large sponges by-catch from Spanish/EU bottom trawl groundfish surveys in NAFO Regulatory Area (Divs. 3LMNO) and Canadian EEZ (Div. 3L): 2005-2007 period

Since 2005, by-catch of vulnerable invertebrates, such as cold-water corals and large sponges, has been studied with special attention in the Spanish/EU bottom trawl groundfish surveys in Northwest Atlantic (NAFO Divs. 3LMNO). Based on this research, twenty-nine different taxa of cold-water corals have been preliminarily identified in the study area: five alcyonaceans, ten gorgonaceans, ten pennatulaceans, three solitary scleractinians and one antipatharian. No colonial scleractinians were recorded during these surveys and reef structures are unlikely to occur in the study area. The main large sponges found belong to the family Geodiidae. The volume of cold-water corals and large sponges in the by-catches was generally low in the regularly-used fishing grounds studied. Most of the by-catches were recorded in hauls carried out in areas outside of regular fishing grounds for the bottom trawlers. By-catches of large gorgonians were recorded in three small areas located in Divs. 3LM (two in Div. 3L and one in Div. 3M), indicating that Vulnerable Marine Ecosystems (VMEs) could occur there. Pennatulaceans, solitary scleractinians, alcyonaceans and antipatharians were also observed as part of bycatch in some hauls carried out in Divs. 3LMO, but it is not clear if these by-catches indicate presence of VMEs in the area sampled. Highest diversity of coral species was found in Div. 3M. Large sponges occurred in deep waters, in a narrow band along Northern slope of the Grand Banks (Div. 3N) and Southern Flemish Pass (Div. 3L) as well as in several patches located in North-eastern and Eastern Flemish Cap. The preliminary information presented here, derived solely from bottom trawl survey by-catch records, it is not enough for identification of VMEs accurately, but it is very valuable to give a general view of where VMEs like to occur or not occur. Previous experience from other North Atlantic high-seas fishing grounds (e.g. NEAFC Regulatory Area) suggests that additional geohabitat mapping and information on fishery footprint will be needed for the accurate delineation of VMEs and for the subsequent adoption of suitable habitat conservation measures such as Marine Protected Areas (MPAs) to preserve cold-water corals and large sponges in NAFO Area

Necrosis aséptica de astrágalo: presentación de un caso en la infancia

Se presenta un caso de necrosis aséptica de astrágalo en la infancia de origen idiopático que, hasta donde sabemos, resulta único en la literatura mundial. Se trata de una niña con un síndrome de Klippel-Trenaunay que debuta a la edad de 8 años con un cuadro de dolor e inflamación intermitente en tobillo derecho. Se realiza estudio mediante radiografías simples, RNM y gammagrafía con "Tc, llegando al diagnóstico de necrosis avascular de astrágalo. Se trata mediante descarga del miembro durante 3 meses, realizando la paciente vida normal con mínimas molestias a los 3 años del diagnósticoWe present one case of idiopathic avascular necrosis of the talus in a child.To our knowledge, this is the first case reported in the literature. The patient is a girl diagnosed of Klippel-Trenaunay syndrome of the ipsilateral limb. When she was 8 years old began with pain and swelling in the right ankle. Simple X-ray, isotopic bone scan and MRI were done, and she was diagnosed of avascular necrosis of the talar dome. The treatment was no weight bearing for three months. She has no sympthoms three years after diagnosis

An analysis of existing production frameworks for statistical and geographic information: Synergies, gaps and integration

The production of official statistical and geospatial data is often in the hands of highly specialized public agencies that have traditionally followed their own paths and established their own production frameworks. In this article, we present the main frameworks of these two areas and focus on the possibility and need to achieve a better integration between them through the interoperability of systems, processes, and data. The statistical area is well led and has well-defined frameworks. The geospatial area does not have clear leadership and the large number of standards establish a framework that is not always obvious. On the other hand, the lack of a general and common legal framework is also highlighted. Additionally, three examples are offered: the first is the application of the spatial data quality model to the case of statistical data, the second of the application of the statistical process model to the geospatial case, and the third is the use of linked geospatial and statistical data. These examples demonstrate the possibility of transferring experiences/advances from one area to another. In this way, we emphasize the conceptual proximity of these two areas, highlighting synergies, gaps, and potential integration. © 2021 by the authors. Licensee MDPI, Basel, Switzerland

CO19 168. Impacto de la hipertensión pulmonar en la evolución de los ancianos sometidos a sustitución valvular aórtica

ObjetivoEstudiar la influencia de la hipertensión pulmonar (HTP) en la evolución de los ancianos sometidos a sustitución valvular aórtica (SVA).Material y métodosDesde octubre de 1999 hasta noviembre de 2009, 517 ancianos (rango 70-87 años) fueron sometidos a SVA. Trescientos cincuenta y cinco (68,7%) enfermos (grupo I) tenían hipertensión pulmonar (ligera 157; moderada 149; grave 49) frente a 162 (31,3%) (grupo II) con presiones pulmonares normales. El seguimiento medio fue de 4,3 años.ResultadosLa edad media fue de 76,4±3,9 años. La fibrilación auricular (29,5 vs 5,6%; p=0,001) y la insuficiencia mitral moderada preoperatorias (13,7 vs 5,1%; p=0,003) fueron más frecuentes en el grupo I. La mortalidad hospitalaria fue 4,3%, siendo significativamente superior en los pacientes con HTP (I: 5,7% vs II: 0,8%; p=0,027). Los pacientes con HTP moderada (7,3%) o grave (13,9%) tuvieron una mortalidad significativamente superior a la de los pacientes con HTP ligera (1,7%) (p=0,016). La supervivencia actuarial a los 5 años, de los pacientes dados de alta, aunque superior en los pacientes sin HTP (I: 80,9% vs II: 90,6%; p=0,162), no alcanzó significación. La HTP moderada-grave se asoció de manera independiente a la mortalidad hospitalaria (odds ratio [OR]: 2,07; p=0,015), pero no a una menor supervivencia en el seguimiento.ConclusionesLa HTP moderada-grave es un factor de riesgo independiente de mortalidad hospitalaria en los ancianos sometidos a SVA. Su influencia en la supervivencia a medio plazo es menos clara
