Résumé : International audience
OBJECTIVES: To better select for patients who most likely will benefit from cardiac surgery among those with infective endocarditis (IE), we aimed to identify preoperative markers associated with poor outcome after cardiac surgery for IE, and to evaluate the accuracy of European System for Cardiac Operative Risk Evaluation (EuroSCORE) II to predict mortality. METHODS: We enrolled all adult patients who underwent cardiac surgery during the acute phase of definite IE (Duke Criteria) in two referral centres for cardiac surgery. Patients were identified through intensive care unit (ICU) electronic databases, and data were collected from medical charts on standardized questionnaire. RESULTS: Between 2002 and 2013, 149 patients (117 males), with a median age of 64 years [interquartile range 52-73], fulfilled the inclusion criteria. Main complications before surgery were left ventricular dysfunction (23%), central nervous system symptomatic events (34%) and septic shock (24%). Most patients (95%) presented with valve regurgitation, and 49% had perivalvular abscess. Surgery was performed with a median delay of 12 days [5-24] after IE diagnosis, and mean EuroSCORE II was 15.8 (13.4-18.1). In-hospital mortality was 21%. Preoperative variables associated with mortality in multivariate analysis were obesity [odds ratio (OR) 3.67 [1.10-12.19], P = 0.03], vegetation extgreater15 mm (OR 6.72 [1.46-30.98], P = 0.01), septic shock (OR 4.87 [1.67-14.28], P = 0.004) and mechanical prosthetic valve IE (OR 4.99 [1.72-28.57], P = 0.007). EuroSCORE II underestimated mortality in patients with predicted mortality over 10%. CONCLUSION: Factors independently predictive of mortality after cardiac surgery for IE are obesity, septic shock, large vegetation and a mechanical prosthetic valve IE. EuroSCORE II underestimates post-cardiac surgery mortality in patients with IE

Résumé : Although Ni isotopes have been shown to be significantly fractionated in terrestrial samples, their use in continental environmental studies has not yet been evaluated. The present study focuses on an ultramafic (UM) massif (Barro Alto, Goias, Brazil) because such areas are naturally rich in Ni. We present developed lateritic weathering profiles. The goal of the study is to evaluate the potential of using Ni isotopes in environmental continental studies by combining its isotopic signature with mineralogy, in order to better understand the geochemical cycling of Ni in UM settings during weathering. As such, Ni isotope values were measured in samples from the Barro Alto UM complex in the main stages of the lateritic weathering profile of UM rocks, including bedrock, ores (saprolitic and lateritic samples) and soil. The mineralogical composition of the samples, with a focus on the different Ni-bearing minerals, was also determined to decipher the potential links between isotopic fractionation and weathering dynamics. Isotopic signatures (δ60Ni) from the natural Ni geochemical cycle include: bedrock samples (δ60Ni = 0.28 ± 0.08‰), ore samples (saprolitic and lateritic, δ60Ni from -0.60 to 0.30‰) and soil samples (δ60Ni from -0.19 to -0.02‰). An overall trend of heavier isotope depletion was observed in the solid phase during weathering (Δ60NiSoil-Bedrock = -0.47‰). The mineralogical results were consistent with the literature and showed that the mineralogy of the lateritic part and soil was dominated by Fe-oxides, whereas clay minerals were the primary Ni phase scavengers in the saprolitic part of the profile. Thus, the formation of Ni-bearing clay minerals and Fe-oxides appeared to lead to depletion in heavier isotopes, which indicates preferential export of heavy isotopes in the dissolved phase. This result is consistent with isotopic signatures measured in the exchangeable pool of the solid phase (Δ60Niexch-total up to 0.47‰), and Ni isotopes appear to be a promising tracer to better understand the biogeochemical Ni cycling on the Earth’s surface.
