Salt Gauging And Stage-Discharge Curve, Avançon De Nant, Outlet Vallon De Nant Catchment

This data set contains the salt gaugings completed over the period 2016 - 2017 to establish a stage-discharge curve at the outlet of the Vallon de Nant catchment. The data set contains also the latest version of the estimated stage-discharge curve, compared to the theoretical curve estimated from the geometric properties of the weir. The salt gaugings have been obtained independently by two different research groups from Institute of Earth Surface Dynamics (IDYST), Faculty of Geosciences and Environement (FGSE), University of Lausanne (UNIL), Stream Biofilm and Ecosystem Research Laboratory (SBER), School of Architecture, Environmental and Civil Engineering (ENAC), Ecole Polytechnique Fédérale de Lausanne (EPFL), Switzerland, The stream gauging station itself was constructed thanks to a joint funding by the Swiss Federal Institute for Forest, Snow and Landscape (WSL), University of Lausanne (chair of Prof. S. Lane) and ETH Zürich (chair of Prof. J. Kirchner). The gauging station is maintained by the Mountain Hydrology and Mass Movements research unit of the Swiss Federal Institute for Forest, Snow and Landscape (WSL) and by the Institute of Earth Surface Dynamics of University of Lausanne

Ultrasound of Subtalar Joint Synovitis in Patients with Rheumatoid Arthritis:Results of an OMERACT Reliability Exercise Using Consensual Definitions

OBJECTIVE: To evaluate the intraobserver and interobserver reliability of the ultrasonographic (US) assessment of subtalar joint (STJ) synovitis in patients with rheumatoid arthritis (RA). METHODS: Following a Delphi process, 12 sonographers conducted an US reliability exercise on 10 RA patients with hindfoot pain. The anteromedial, posteromedial, and posterolateral STJ was assessed using B-mode and power Doppler (PD) techniques according to an agreed US protocol and using a 4-grade semiquantitative grading score for synovitis [synovial hypertrophy (SH) and signal] and a dichotomous score for the presence of joint effusion (JE). Intraobserver and interobserver reliability were computed by Cohen's and Light's κ. Weighted κ coefficients with absolute weighting were computed for B-mode and PD signal. RESULTS: Mean weighted Cohen's κ for SH, PD, and JE were 0.80 (95% CI 0.62-0.98), 0.61 (95% CI 0.48-0.73), and 0.52 (95% CI 0.36-0.67), respectively. Weighted Cohen's κ for SH, PD, and JE in the anteromedial, posteromedial, and posterolateral STJ were -0.04 to 0.79, 0.42-0.95, and 0.28-0.77; 0.31-1, -0.05 to 0.65, and -0.2 to 0.69; 0.66-1, 0.52-1, and 0.42-0.88, respectively. Weighted Light's κ for SH was 0.67 (95% CI 0.58-0.74), 0.46 (95% CI 0.35-0.59) for PD, and 0.16 (95% CI 0.08-0.27) for JE. Weighted Light's κ for SH, PD, and JE were 0.63 (95% CI 0.45-0.82), 0.33 (95% CI 0.19-0.42), and 0.09 (95% CI -0.01 to 0.19), for the anteromedial; 0.49 (95% CI 0.27-0.64), 0.35 (95% CI 0.27-0.4), and 0.04 (95% CI -0.06 to 0.1) for posteromedial; and 0.82 (95% CI 0.75-0.89), 0.66 (95% CI 0.56-0.8), and 0.18 (95% CI 0.04-0.34) for posterolateral STJ, respectively. CONCLUSION: Using a multisite assessment, US appears to be a reliable tool for assessing synovitis of STJ in RA
