MOESM1 of Respiratory changes of the inferior vena cava diameter predict fluid responsiveness in spontaneously breathing patients with cardiac arrhythmias
Additional file 1: Figure S1. A, Receiver operating characteristics (ROC) curve of the collapsibility index (cIVC-st) and the inspiratory diameter (iIVC-st) of the inferior vena cava during a standardized inspiratory maneuver before volume expansion (VE) to discriminate responders from nonresponders to VE in the overall population. B, ROC curve of the collapsibility index (cIVC-sp) and the inspiratory diameter (iIVC-sp) of the inferior vena cava during unstandardized spontaneous breathing before VE to discriminate responders from nonresponders to VE in the overall population. Figure S2. A, Linear correlation between the collapsibility index of the inferior vena cava under standardized breathing (cIVC-st) before volume expansion (VE) and VE-induced change in the velocity time integral of aortic blood flow (VTIao). B, Linear correlation between the inspiratory diameter of the inferior vena cava under standardized breathing (iIVC-st) before VE and VE-induced change in VTIao. Figure S3. Scatterplot of individual values before volume expansion (VE) for the collapsibility index (cIVC-sp), minimum-inspiratory diameter (iIVC-sp), and the end-expiratory diameter of the inferior vena cava (eIVC-sp) under unstandardized spontaneous breathing in responders and nonresponders to VE

Schematic representation of key responses to MERS-CoV related to outcome.
<p>Left panel: Coronavirus are recognized by the immune system through the activation of cytosolic and membranous pattern recognition receptors (MDA-5 and RIG-1). This activation triggers IRF 3 which leads to the production of IFNα. IFN activates anti viral effectors like T CD8+ cells allowing viral clearance. Right panel: In the absence of recognition, the decrease in IRF 3 is associated to a decreased production of IL 12 and IFNγ. IL 10 production further represses IFNγ secretion leading to a decreased CD8 T lymphocytes proliferation and an increased viral replication.</p

Additional file 2: of Comparison of fluid balance and hemodynamic and metabolic effects of sodium lactate versus sodium bicarbonate versus 0.9% NaCl in porcine endotoxic shock: a randomized, open-label, controlled study
Study design. During preparation period, all animals received 25 mL/kg 0.9% NaCl to prevent hypovolemia. When all preparations were completed, a 30-min period was allowed to stabilize the measured variables. Measurements were taken over a 5-h period. All animals were administered 5 μg/kg/min Escherichia coli lipopolysaccharide (LPS) (serotype 055:B5; Sigma Chemical Co., St. Louis, MO, USA). If MAP fell below 65 mmHg, 2.5 mL/kg infusion of NaCl 0.9% was given as rescue therapy every 15 min. We studied three groups receiving 450 mL (from T30 to T300) of different fluids as follows: 11.2% hypertonic sodium lactate AP-HP® (AGEPS, Paris, France) (SL group), 0.9% NaCl (NC group), and 8.4% hypertonic sodium bicarbonate (SB group). In order to inject an equivalent energy supply, 5% glucose solution (Baxter SAS, Guyancourt, France) was perfused in the NC and SB groups. Finally, in order to maintain the same fluid intake in the three groups, the SL group received 780 mL sterile water for injection (Baxter SAS, Guyancourt, France) in place of 5% glucose solution from T30 to T300. SL, Sodium lactate group; SB, sodium bicarbonate group; NC, NaCl 0.9% group; MAP, mean arterial pressure; HR, heart rate; BP, blood pressure; PBP, pulmonary blood pressure; PCWP, pulmonary capillary wedge pressure; RAP, right atrial pressure; SvO2, mixed venous oxygen saturation; CI, cardiac index; SDF, sidestream dark field; NIRS, near-infrared spectroscopy; A-VBG, arterial and venous blood gas.
