Biodiversity and ecology of Hirudinea (Annelida) from the Natural Reserve of Isla Martín García, Río de la Plata, Argentina

The Island of Martin Garcia lies at the confluence of the Uruguay and Paraná Rivers (upper Río de la Plata). This island is an outcrop of the crystalline basement. Due to basalt exploitation the island exhibits several ponds covered by carpets of free-floating macrophytes. Seven major environmental variables were measured: water and air temperature, percentage of oxygen saturation, dissolved oxygen, electrical conductivity, total dissolved solids and pH. Eleven leech species were found, Helobdella striata, H. diploides, H. adiastola and H. hyalina were new records. UPGMA clustering of species based on their occurrence in different ecological conditions revealed three main species groups. Canonical Correspondence Analysis (CCA) explained 97.2% of the correlation between species and environmental variables. H. triserialis shows the widest range of tolerance, H. hyalina shows positive relationships to conductivity; H. diploides shows a high correlation with dissolved oxygen, H. striata, H. lineata, and S. similis are negatively correlated with water temperature, and H. simplex is positively correlated with pH. Relationships between the species richness (S) and the sampling sites were negatively correlated with water temperature and positively correlated with dissolved oxygen. Leech biodiversity from the water bodies of Martín García Island, shows a great diversity of species and a wide plasticity regarding the characteristics of the environmental factors considered

Tradução e adaptação para a língua portuguesa do In-hospital Utstein Style Traducción y adaptación al idioma portugués del instrumento In-hospital Utstein Style Translation and adaptation of the In-Hospital Utstein Style into the portuguese language

A parada cardiorrespiratória (PCR) é um evento potencialmente letal e a qualidade do atendimento prestado depende da agilidade, conhecimento e habilidade de toda a equipe envolvida. Desenvolvido em 1997, o In-hospital Utstein Style é um relatório padrão para coleta de dados significativos em PCR. O estudo objetivou realizar a tradução e adaptação à língua portuguesa do instrumento. O instrumento foi submetido ao processo de tradução e adaptação cultural. O resultado deste processo gerou um instrumento aplicado em fase de pré-teste a 20 pacientes vítimas de PCR. As variáveis de resultado não foram coletadas, pois pressupõe o acompanhamento destes pacientes ao longo do tempo. O ritmo de PCR mais comum foi atividade elétrica sem pulso (65%); o tempo médio para desfibrilar foi de 1,25 minutos. Houve itens sem resposta. Podemos concluir que o instrumento é aplicável à realidade brasileira, buscando melhor atendimento ao evento da PCR.<br>El paro cardiopulmonar (PCP) es un estado potencialmente letal, donde la calidad del servicio depende de la agilidad, conocimiento y habilidad del equipo involucrado. El In-hospital Utstein Style fue elaborado en 1997. Este instrumento que recolecta datos de importancia durante un PCP fue traducido y adaptado al portugués. De esta forma fue sometido al proceso de traducción y adaptación cultural. Se obtuvo como resultado un instrumento, el cual fue aplicado a 20 victimas de PCP a través de un pre-test. Las variables de resultado no fueron consideradas en la recolección de datos, pues suponía el seguimiento de los pacientes por un periodo prolongado. El ritmo del PCP más común fue la actividad eléctrica sin pulso (65%) y el tiempo promedio de desfibrilación fue de 1,25 minutos. Algunos ítems no fueron respondidos. Se concluye que el instrumento puede ser aplicado al contexto brasileño, en busca de una mejor atención en casos de PCP.<br>Cardiopulmonary arrest (CPA) is a potentially lethal event in which the quality of the service depends on agility, knowledge and the skills of all of the involved team. The development of the guide identifying the significant points during the procedure of an in-hospital CPA appeared in 1997, with the creation of the In-Hospital Utstein. The purpose of this study was the translation and adaptation of the procedures into the Portuguese language. Outcomes of this process resulted in a pre-test instrument administered on 20 CPA patients. The outcome variables were not collected, because it involved accompanying these patients over a lengthy period of time. The most common CPA rhythm was pulseless electrical activity (65%); the defibrillation average time was 1.25 minutes. Some information was not recorded. In conclusion, the instrument is adaptable to the Brazilian reality, therefore improving care administered during the CPA event
