    BACKGROUND: Aspecific scoring systems are used to predict the risk of death postsurgery in patients with infective endocarditis (IE). The purpose of the present study was both to analyze the risk factors for in-hospital death, which complicates surgery for IE, and to create a mortality risk score based on the results of this analysis. METHODS AND RESULTS: Outcomes of 361 consecutive patients (mean age, 59.1\ub115.4 years) who had undergone surgery for IE in 8 European centers of cardiac surgery were recorded prospectively, and a risk factor analysis (multivariable logistic regression) for in-hospital death was performed. The discriminatory power of a new predictive scoring system was assessed with the receiver operating characteristic curve analysis. Score validation procedures were carried out. Fifty-six (15.5%) patients died postsurgery. BMI >27 kg/m2 (odds ratio [OR], 1.79; P=0.049), estimated glomerular filtration rate 55 mm Hg (OR, 1.78; P=0.032), and critical state (OR, 2.37; P=0.017) were independent predictors of in-hospital death. A scoring system was devised to predict in-hospital death postsurgery for IE (area under the receiver operating characteristic curve, 0.780; 95% CI, 0.734-0.822). The score performed better than 5 of 6 scoring systems for in-hospital death after cardiac surgery that were considered. CONCLUSIONS: A simple scoring system based on risk factors for in-hospital death was specifically created to predict mortality risk postsurgery in patients with IE

    Paul Claudel en Chine

    « C'était le temps de Taotaïs, des mandarins à plume de paon et à boutons de toutes couleurs, des pelisses de zibeline, des examens qui chaque année, à l'époque du choléra, mettaient en mouvement un peuple de pinceaux… » L'auteur de ces lignes, Paul Claudel, avait vingt-sept ans lorsqu'il fut nommé Consul de France en Chine : le jeune diplomate français débarqua à Shanghai en juillet 1895 et découvrit alors l'empire de la fin de la dynastie des Qin. Ses différentes affectations lui permirent de parcourir aussi bien le sud que le nord du pays, à Hong-Kong, Hankou et surtout Fuzhou, à Pékin et Tianjin. Paul Claudel ne rentra en Europe qu'en 1909, après quatorze années de séjour dans l'empire du Milieu. Profondément marqué par cette expérience dont il se souviendra comme du « stage du magicien au pays des génies », l'écrivain compose pendant sa mission quelques-unes de ses œuvres les plus importantes : le poète donne les proses poétiques de Connaissance de l'Est, élabore l'Art poétique comme les Cinq Grandes Odes, le dramaturge imagine l'étonnant et méconnu « drame chinois » du Repos du Septième jour et le célèbre Partage de Midi. Les études réunies dans ce volume en hommage au grand spécialiste de ce sujet que fut le professeur Gilbert Gadoffre (1911-1995), par Pierre Brunel et Yvan Daniel, portent toutes sur l'expérience chinoise de Paul Claudel et ses échos dans son œuvre littéraire. Elles montrent l'intense créativité intellectuelle et culturelle stimulée par le contact avec la Chine et son empreinte, aussi bien dans la poésie que dans le théâtre claudéliens.Pour Gilbert Gadoffre

    Vapor-liquid equilibrium and molecular simulation data for carbon dioxide (CO 2 ) + trans-1,3,3,3-tetrafluoroprop-1-ene (R-1234ze(E)) mixture at temperatures from 283.32 to 353.02 K and pressures up to 7.6 MPa

    International audienceIsothermal Vapor-Liquid Equilibrium (VLE) data for the binary mixture of CO 2 + R-1234ze(E)(trans-1,3,3,3-tetrafluoroprop-1-ene) were measured using a static-analytic method apparatus at seven temperatures between 283.32 and 353.02 K and pressures up to 7.6 MPa. For temperatures over the critical temperature of pure CO 2 , the critical compositions and pressures of binary mixtures were approximated applying power laws with asymptotic behavior at critical point. The data were well correlated using the Peng-Robinson equation of state incorporating the generalized alpha function, with the Wong-Sandler mixing rules involving NRTL activity coefficient model. The experimental and correlated phase compositions were compared with Gibbs Ensemble Monte Carlo simulation data obtained at 293.15 K and 353.02 K. Though the molecular simulation predictions at low temperature (293.15 K) properly match experimental data, a slight shift appeared at high temperature (353.02 K), and the expected convergence of phase compositions near critical point was not fully observed
