Introduction and objectives: The results of the Radcong-21 Registry of the Spanish Society of Pediatric Cardiology and Congenital Heart Disease Working Group on Hemodynamics are described to analyze data, establish updated reference parameters, and compare them to other registries. Methods: Retrospective, cross-sectional, observational, multicenter registry of patients with congenital heart disease undergoing cardiac catheterization in 2021. Each cath lab sent the last 100 cases performed prior to January 2022. A descriptive analysis was conducted of anthropomorphic variables, procedural (grouped by type and radiation exposure categories [REC]) and technical characteristics, and dosimetric parameters with additional review of all values outside the 95%CI of the median. Results: A total of 1090 procedures performed in 11 cath lab of 10 hospital centers were analyzed. Age distribution: 22.8% < 1 year, 60.7% between 1-18 years, and 16.4% > 18 years. In dose area product (DAP)/Kg and DAP/Kg/fluoroscopy, the distribution was very similar regardless of the type of cath lab as is the case with most pediatric patients in terms of age, weight, and REC group. The DAP/Kg was higher in the REC I and III groups compared to other countries with registries and improvement programs in this area (78% and 8,3%, respectively). Conclusions: Representative data of dosimetric parameters by age and procedures in congenital cardiac catheterizations were obtained in Spain back in 2021. DAP/Kg is the parameter with the lowest dispersion in the sample. There is room for improvement compared to other countries with optimization programs in this area., Introducción y objetivos: Se describen los resultados del Registro Radcong-21 del Grupo de Trabajo de Hemodinámica de la Sociedad Española de Cardiología Pediátrica y Cardiopatías Congénitas con el objetivo de analizar los datos, establecer parámetros de referencia actualizados y compararlos con otros registros. Métodos: Registro multicéntrico, observacional, transversal y retrospectivo de pacientes con cardiopatías congénitas tratados con cateterismo cardiaco en 2021. Cada sala de hemodinámica remite los últimos 100 casos realizados hasta enero de 2022. Análisis descriptivo de variables antropomórficas, procedimientos (agrupados por tipo y riesgo estimado de radiación [RER]), características técnicas y parámetros dosimétricos. Revisión adicional de todos los valores fuera del intervalo de confianza del 95% de la mediana. Resultados: Se analizaron 1.090 procedimientos en 11 salas de hemodinámica de 10 centros hospitalarios. De los pacientes, el 22,8% fueron < 1 año, el 60,7% entre 1 y 18 años, y el 16,4% > 18 años. Los valores del producto dosis-área (PDA)/kg y del PDA/kg/fluoroscopia fueron muy similares independientemente del tipo de sala, al igual que ocurre con la edad, el peso y el grupo RER en la mayor parte de las salas pediátricas. El PDA/kg fue superior en los grupos RER I y III comparado con otros países con registros y programas de mejora activos en este campo (un 78 y un 8,3%, respectivamente). Conclusiones: Se obtienen datos representativos de los parámetros dosimétricos por edad y procedimientos en los cateterismos cardiacos congénitos en España en el año 2021. El PDA/kg es el que tiene menor dispersión en la muestra total. Existen áreas de mejora en comparación con otros países con programas de optimización.

Introduction and objectives: This is the 2021 annual activity report from the Interventional Cardiology Association of the Spanish Society of Cardiology (ACI-SEC), and the Interventional Working Group of the Spanish Society of Pediatric Cardiology (GTH-SECPCC). Methods: All Spanish centers with cath lab capabilities and interventional activity in congenital heart diseases were invited to participate. Data were collected online, analyzed by an external company, and ACI-SEC and GTH-SECPCC members. Results: A total of 16 centers participated—15 public and 1 private—including 34 cath labs with experience in congenital heart diseases, 7 of them (20.5%) exclusively dedicated to pediatric patients. A total of 1094 diagnostic studies (4.5% more than 2020) and 1553 interventional catheterizations (5.8% more than 2020) were registered. The most common procedures were atrial septal defect closure (336 cases), pulmonary branch artery angioplasty (231 cases), and percutaneous closure of the patent ductus arteriosus (228 cases). Interventional procedures were considered successful in 95% of the cases with rates of major procedural complication and in-hospital mortality of 2.7% and 0.2%, respectively. Conclusions: This is the second Spanish Cardiac Catheterization in Congenital Heart Diseases Registry report. A significant increase of diagnostic and interventional procedures was reported with a special increase of percutaneous valve implantation, ductus arteriosus closure, and aortic angioplasty. Most interventional techniques continue to demonstrate excellent safety and efficacy outcomes., Introducción y objetivos: La Asociación de Cardiología Intervencionista de la Sociedad Española de Cardiología (ACI-SEC) y el Grupo de Trabajo de Hemodinámica de la Sociedad Española de Cardiología Pediátrica y Cardiopatías Congénitas (GTH-SECPCC) presentan su informe anual de actividad hemodinámica en cardiopatías congénitas correspondiente al año 2021. Métodos: Se invitó a participar a los centros españoles con laboratorio de hemodinámica y actividad intervencionista en cardiopatías congénitas. La recogida de datos fue telemática y su análisis lo efectuó una empresa externa junto con miembros de la ACI-SEC y el GTH-SECPCC. Resultados: Participaron 16 centros (15 públicos y 1 privado) que acumulan 34 salas de hemodinámica con actividad en cardiopatías congénitas, 7 (20,5%) de ellas con dedicación exclusiva a pacientes pediátricos. Se registraron 1.094 estudios diagnósticos (5,1% más que en 2020) y 1.553 cateterismos intervencionistas (6,4% más que en 2020). Las técnicas más frecuentes fueron el cierre de comunicación interauricular (336 casos), la angioplastia de ramas pulmonares (231 casos) y el cierre de ductus (228 casos). Respecto al año anterior se incrementaron significativamente las técnicas de implantación de válvulas percutáneas (29,3%), cierre de ductus (20,6%) y angioplastia aórtica (12,8%). La tasa de éxito en los procedimientos intervencionistas fue del 95%, con una tasa de complicaciones mayores del 2,7% y una mortalidad intrahospitalaria del 0,2%. Conclusiones: Este trabajo es la segunda publicación del Registro Español de Intervencionismo en Cardiopatías Congénitas. Se ha constatado un aumento significativo de los procedimientos diagnósticos y terapéuticos, destacando el incremento en la implantación de válvulas percutáneas, el cierre de ductus y la angioplastia aórtica. La mayoría de las técnicas intervencionistas siguen demostrando excelentes datos de seguridad y eficacia.

Recent studies have shown that coastal and shelf cephalopod populations have increased globally over the last six decades. Although cephalopod landings are dominated by the squid fishery, which represents nearly 80% of the worldwide cephalopod catches, octopuses and cuttlefishes represent ∼10% each. Total reported global production of octopuses over the past three decades indicates a relatively steady increase in catch, almost doubling from 179,042 t in 1980 to 355,239 t in 2014. Octopus fisheries are likely to continue to grow in importance and magnitude as many finfish stocks are either fully or over-exploited. More than twenty described octopus species are harvested from some 90 countries worldwide. The current review describes the major octopus fisheries around the globe, providing an overview of species targeted, ecological and biological features of exploited stocks, catches and the key aspects of management

The jumbo, or Humboldt, squid Dosidicus gigas currently accounts for about one third of total world squid landings ( Arkhipkin et al., 2015). It is the largest and most abundant ommastrephid squid in the eastern Pacific, where it is endemic. It is an important predator throughout its geographical range ( Markaida, 2006, Field et al., 2013 and Alegre et al., 2014) and is prey for large marine mammals, particularly sperm whales in the southeastern Pacific, for which it is the single most important food species ( Clarke et al., 1988 and Nigmatullin et al., 2001). The large-scale fishery for D. gigas began in the 1980s in the Mexican northeast Pacific ( Ehrhardt et al., 1983) and this was followed in the 1990s in Peruvians waters of the southeast Pacific (Yamashiro et al., 1998). Annual catches increased from 19,000 t in the 1980s to 847,000 t in 2013 (ftp://ftp.fao.org/FI/STAT/summary/inicio.htm). It became one of the largest marine invertebrate fisheries in the world, and the first Peruvian fishery to be fully monitored by observers at sea in the Peruvian EEZ and at ports where landings are made (Guevara-Carrasco et al., 2015). During this period D. gigas has shown significant changes in abundance, distribution and population structure in both the northeast and southeast Pacific. These have been associated with (1) direct effects of environmental variability, (2) changes in the availability of prey, especially during the early ontogenetic stages, (3) changes in predation, disease and parasitism, and (4) possible reduction of natural mortality through the exploitation of their predators as suggested by Rodhouse (2008). The development of an artisanal fishery in Peruvian waters (2350 artisanal boats with an average capacity of 9.8 tons) and in Chilean waters, as well as an industrial fishery outside the Peruvian and Chilean EEZs (Chen et al., 2008) have taken place against the background of these changes

Some 290 species of squids comprise the order Teuthida that belongs to the molluscan Class Cephalopoda. Of these, about 30–40 squid species have substantial commercial importance around the world. Squid fisheries make a rather small contribution to world landings from capture fisheries relative to that of fish, but the proportion has increased steadily over the last decade, with some signs of recent leveling off. The present overview describes all substantial squid fisheries around the globe. The main ecological and biological features of exploited stocks, and key aspects of fisheries management are presented for each commercial species of squid worldwide. The history and fishing methods used in squid fisheries are also described. Special attention has been paid to interactions between squid fisheries and marine ecosystems including the effects of fishing gear, the role of squid in ecosystem change induced by overfishing on groundfish, and ecosystem-based fishery management.
