Atrial fibrillation(AF)is the most common arrhythmia in the elderly and its incidence increases with aging.[1]Electrical cardioversion is used as a strategy for rhythm control in patients with supraventricular *** octagenarians,there are challenges associated with the indication for electrical cardioversion,such as the use of appropriate sedation and anticoagulant *** decisions in clinical practice for these patients derive from observational data and personal experience,since octagenarians represent a minority of patients included in randomized clinical *** evidence is available regarding the clinical context of electrical cardioversion in this vulnerable ***,we aimed to describe the clinical profile of octagenarians undergoing electrical cardioversion in a cardiology reference center from 2014 to 2018.

soil erosion and sedimentation are among the most serious global environmental *** and water conservation measures have been proven effective ways to reduce soil *** objective of this study was to evaluate the impact of three approaches of soil and water conservation measures(soil management,vegetative measures,and structural practices)on soil erosion and water balance of two paired agricultural watersheds located in southern *** and sediment monitoring was carried out from 2016 to 2019 in the two small paired agricultural watersheds;called North watershed(NW)and south watershed(sW).Modeling using soil&Water Assessment Tool(sWAT)was performed to simulate individual(nine scenarios)and combined(four scenarios)best management practices(BMPs),by including the three *** the nine individual BMP scenarios,the most effective in reducing soil erosion was crop rotation and cover crop(sediment yield,sY,reduction of 38.4 for NW,and 28.8%for sW).Among the four combined scenarios,the association of all conservation approaches was the most effective in reducing soil erosion(sY reduction of 46 for NW,and 41.5%for sW),followed by the vegetative measures scenario(sY reduction of 43.5 and 34.1%for NW and sW).All combined scenarios increased infiltration and subsurface water components,and decreased surface *** findings of this study can help farmers and policymakers choosing appropriate BMPs to reduce current soil erosion problems and promote water and soil conservation.

Ecological and hydrological impacts are expected when watersheds are under commercial *** this study we evaluated event-based hydrology and sedimentation in paired watersheds under commercial eucalyptus and grasslands ***,suspended sediment concentration,and sediment production were measured and simulated with the Limburg soil Erosion Model(LIsEM)in paired hydrographic watersheds located in southern Brazil;one occupied with 7-years old Eucalyptus saligna plantation(forest watershed-FW;0.83 km^(2))and another Pampa biome with native and exotic grasses used for beef cattle production(grassland watershed-GW;1.10 km^(2)).The effect of rainfall on hydrological and sedimentological variables was more evident in GW compared with *** shape of the hydrograph was steepest in GW,with rapid,marked increase and decrease in flow during *** parameters changed for model calibration in FW and GW were soil saturated hydraulic conductivity,initial soil moisture,and Manning roughness coefficient,whereby the statistical performance was classified as good(NsE>0.75).Fourteen events different from those used in the calibration process were validated for FW and GW,with NsE index classified as“good”and“very good”for *** study shows limitations of LIsEM in calibrating and validating the sediment yield for individual events due to the spatial variability of factors controlling soil *** validated modeling results of this study may be applied in simulating soil and crop scenarios in watersheds cultivated with commercial forest and grassland for grazing.
