The comparative study between thromboelastography and conventional coagulation tests in ischemic cerebral vascular disease / 中华急诊医学杂志

Objective@#To explore the correlation and consistency between thromboelastography (TEG) and traditional coagulation tests (CCTs) in ischemic cerebral vascular disease (ICVD).@*Methods@#Totally 108 ICVD patients admitted to Nanyang Central Hospital from May 1 to October 31 2018 were enrolled. Patients’ TEG parameters (R value, K value, Angle value, MA value, CI value and G value) and CCTs parameters (PT, APTT, TT, and FIB) were collected and analyzed retrospectively. The Spearman correlation coefficient was used to explore the correlation between TEG and CCTs parameters, and Kappa (κ) to explore the consistency in determining the coagulation status of the patients. The ROC curve was used to analyze the predictive value of TEG parameters for abnormal results of CCTs, and the results of TEG and CCTs were comprehensively analyzed to evaluate the ability to predict the coagulation status of patients.@*Results@#(1) PLT was positively correlated with MA value and G value; PT and APTT were positively correlated with K value; TT was positively correlated with R value and K value; FIB was positively correlated with Angle value, MA value and G value. TT was negatively correlated with Angle value and CI value; FIB was negatively correlated with K value. (2) PT and MA values, PT and G values, FIB and MA values, FIB and G values were accordant in valuing the hypoxic state of ICVD patients. (3) PLT and Angle values, PLT and MA values, PLT and CI values, PLT and G values were accordant in assessing hypercoagulable status of ICVD patients; FIB and Angle values, FIB and MA values, FIB and CI value, and FIB and G value were consistent in evaluating the hypercoagulable state of ICVD patients. (4) For detecting TT>20 s, the AUC of K value and Angle value were 0.648, 0.651, respectively; For detecting FIB>4 g/L, the AUC of Angle value and MA value were 0.717 and 0.747, respectively; For detecting PLT>300×109/L, the AUC of MA value was 0.808 (all P<0.05).@*Conclusions@#There is weak correlation and consistency between TEG and CCTs parameters in ICVD patients. The TEG parameters have good predictive value in evaluating the abnormal results of CCTs, but cannot replace the CCTs. Combination of these two methods can better reflect the coagulation status of patients, so as to afford assistance.

Riqueza y composición de la fauna de anuros en la región oriental de la Reserva Natural Provincial Esteros del Iberá, Corrientes, Argentina / Anuran richness and composition in the Eastern region of Iberá Wetlands Provincial Nature Reserve, Corrientes, Argentina

Anuran richness and composition in the Eastern region of Iberá Wetlands Provincial Nature Reserve, Corrientes, Argentina. In recent decades, the concern for biodiversity conservation has increased in importance, especially due to the loss of highly biodiverse natural areas such as wetlands. Despite the high fauna diversity inhabiting the Iberá, the information about its composition, structure and dynamics is scarce, and amphibians are typical and conspicuous representatives of these Neotropical areas. To generate new information about this group, the amphibian composition from two villages (Paraje Galarza and Colonia Carlos Pellegrini),belonging to two different fitogeographic regions in the Eastern edge of the Iberá, were described and compared. Samples were taken, from a respective area of 100km² that included five landscape units (wetlands, streams and swamps, grasslands, forest and apermanent/temporal pond) each, during the four seasons between January 2007 and March 2008. The techniques applied were the Complete Species Inventories (Unrestricted direct search) and Visual Encounter Surveys (VES). A total of 28 species were found, and represented the 70% of the previously registered taxa for the whole wetland. Scinax similis and Rhinella azarai were recorded for the first time in the Iberá Wetlands. No significant differences were found in the anuran specific richness between the surveyed villages, since the 95% of confidence intervals for the species accumulation curves were superimposed. In both villages, the wetlands, streams and swamps, and the permanent pond landscapes, showed the higher species richness when compared to the others. According to the Chao2, Jacknife1 and ICE estimators, the inventory completeness of species, oscillated among 88% and 98% for the whole area. The dendrogram analysis based on the Jaccard similarity index, showed that wetlands, streams and swamps were grouped and well separated from grasslands. To guarantee ...

Los anfibios son representantes típicos y conspicuos de los ecosistemas de humedales neotropicales, tales como los Esteros del Iberá, su preservación está en íntima relación con la conservación de la biodiversidad. A pesar de la alta diversidad faunística presente en los Esteros del Iberá, poco se conoce de la composición y estructura de su fauna, lo que hace necesario incrementar y actualizar el conocimiento sobre estos aspectos. En el presente trabajo se describe y se compara la composición de la fauna de anuros de dos localidades (Paraje Galarza y Colonia Carlos Pellegrini) situadas en el borde oriental del Iberá. Entre enero 2007 y marzo 2008, en ambas localidades seleccionadas, se realizaron muestreos mediante las técnicas: Inventario Completo de especies y Relevamiento por Encuentro Visual (VES). De los 40 táxones de anfibios citados para los Esteros del Iberá, se hallaron 28 especies, lo que representó el 70% de las especies registradas para toda la Reserva. Scinax similis y Rhinella azarai constituyeron los primeros registros para los Esteros del Iberá. La completitud del inventario osciló entre el 88% y el 98%. La similitud en la composición específica de anuros fue relativamente alta entre las localidades estudiadas (Ij =0.64).
