Response by Lima et al to Letter Regarding Article, “Field Assessment Stroke Triage for Emergency Destination: A Simple and Accurate Prehospital Scale to Detect Large Vessel Occlusion Strokes”
Stroke, 2016Co-Authors: Fabricio O Lima, Gisele Sampaio Silva, Raul G NogueiraAbstract:We would like to thank Heldner et al1 for taking an interest on our work and applying the Field Assessment Stroke Triage for Emergency Destination scale (FAST-ED) to their large patient cohort. Triage for stroke centers will undergo major changes given the recently proven benefit of endovascular approaches in the treatment of large vessel occlusion strokes (LVOS). The FAST-ED scale was designed to aid in the decision to triage patients to primary stroke center versus comprehensive stroke centers in the prehospital setting. In STOPStroke (n=727; 33% LVOS), FAST-ED had comparable accuracy to predict LVOS to the National Institutes of Health Stroke Scale score (NIHSS) and higher accuracy than Rapid Arterial Occlusion Evaluation scale (RACE) and Cincinnati Prehospital Stroke Severity Scale (CPSSS) (area under the curve: FAST-ED=0.81 as reference; NIHSS score of =0.80, P =0.28; RACE score of =0.77, P =0.02; and CPSSS score of=0.75, P =0.002).2 Heldner et al1 independently corroborated …

Field Assessment stroke triage for emergency destination a simple and accurate prehospital scale to detect large vessel occlusion strokes
Stroke, 2016Co-Authors: Fabricio O Lima, Gisele Sampaio Silva, Karen L Furie, Michael Frankel, Erica C S Camargo, Diogo C Haussen, Aneesh B Singhal, Walter J Koroshetz, Wade S Smith, Raul G NogueiraAbstract:Background and Purpose—Patients with large vessel occlusion strokes (LVOS) may be better served by direct transfer to endovascular capable centers avoiding hazardous delays between primary and comprehensive stroke centers. However, accurate stroke Field triage remains challenging. We aimed to develop a simple Field scale to identify LVOS. Methods—The Field Assessment Stroke Triage for Emergency Destination (FAST-ED) scale was based on items of the National Institutes of Health Stroke Scale (NIHSS) with higher predictive value for LVOS and tested in the Screening Technology and Outcomes Project in Stroke (STOPStroke) cohort, in which patients underwent computed tomographic angiography within the first 24 hours of stroke onset. LVOS were defined by total occlusions involving the intracranial internal carotid artery, middle cerebral artery-M1, middle cerebral artery-2, or basilar arteries. Patients with partial, bihemispheric, and anterior+posterior circulation occlusions were excluded. Receiver operating ch...

visual Field Assessment of soil structural quality in tropical soils
Soil & Tillage Research, 2014Co-Authors: Mansonia Alejandra Pulido Moncada, Donald Gabriels, Deyanira Lobo, Wim CornelisAbstract:A B S T R A C T Visual Field Assessments have already been tested for ‘temperate’ soils, but there is scant information about their applicability to ‘tropical’ soils. This survey contributes to the validation of the visual Field Assessments by comparing the performance of three of such methods on ‘tropical’ soils. This study was conducted across six different soils with contrasting soil type and land use, in the central-northern part of Venezuela between November 2011 and January 2012. Scores provided by the soil quality scoring procedure (SQSP), the visual evaluation of soil structure (VESS), and the visual soil Assessment (VSA), as well as soil physical properties were measured to assess the soil’s structural quality. All methods showed that soil structural quality was unfavourable on a loamy soil (Alfisol) with continuous cereal growth, conventional tillage and low soil organic carbon (SOC), as well as on a silty clay soil (Alfisol) under natural vegetation and cattle production. Where SQSP scores ranged between 1 (extremely firm) and 2 (firm), VESS scores ranged from 4 (compact) to 5 (very compact), and VSA scores were between 0 (poor) and 0.5 (moderately poor). The sandy clay loam (Ultisol) and clay loam (Mollisol) soils under no-tillage and with high SOC had the best soil quality. In our ‘tropical’ Venezuelan soils there was also high correlation (P < 0.01) between the visual Assessment scores and soil physical properties such as bulk density (BD), porosity, SOC, and saturated hydraulic conductivity (Ksat), as has been reported for ‘temperate’ soils. A visual poor condition of soil structure corresponded to BD values higher than 1.4 Mg m � 3 , porosity lower than 0.5 m 3 m � 3 , SOC below 25 g kg � 1 , and Ksat (log) values under 0.5 cm h � 1 . In those cases where the rooting system could not be evaluated because of fallow, VSA and VESS appeared to be the most appropriate methods for assessing the soil structure. The rating of the indicator ‘number of earthworms’ should be adjusted for ‘tropical’ soils; this shall improve the accuracy of the VSA method. These methods were capable of distinguishing the different soil structural quality, and are therefore suitable for assessing soil structural quality of ‘tropical’ soils with contrasting soil type and land use.
