Research paper thumbnail of Prediction of fluid responsiveness with the LiDCO system

Critical Care, 2011

IntroductionVariation in stroke volume (SV) or related parameters induced by passive leg raising ... more IntroductionVariation in stroke volume (SV) or related parameters induced by passive leg raising (PLR) measured by several non-invasive methods has been demonstrated to reliably predict fluid responsiveness [1]. The aim of this study was to assess whether variation in SV measured by LiDCO can predict fluid responsiveness in shock states.MethodsICU patients with signs of shock were enrolled. History, clinical information and echocardiogram were obtained. After calibration, hemodynamic evaluation was performed by LiDCO in four subsequent steps: T1 in semi-recumbent position; T2 during PLR; T3 in baseline position; T4 after infusion of 500 ml NaCl 0.9% in 15 minutes. On each step, the heart rate (HR), mean arterial pressure (MAP), absolute and indexed cardiac output and stroke volume (CO/CI, SV/SVI) were measured by LiDCO and the aortic velocity time integral (VTI) by transthoracic echocardiography. Patients whose SVI increased at least 10% after volume load were classified as responders. ...

Research paper thumbnail of A histological investigation of the occurrence of non-reproductive female bluefin tuna Thunnus thynnus in the Mediterranean Sea

Three hundred and twenty-six ovary samples were collected from adults captured at different locations in the Mediterranean Sea during the reproductive seasons between 1998 and 2008. Only three specimens were considered to be in a non-reproductive state: two of them were in a reabsorbing state showing ovaries with early vitellogenic oocytes and extensive α and β atresia of vitellogenic follicles; the third showed gonads with perinucleolar oocytes and was considered to be in a resting state. The low occurrence of non-reproductive individuals found in this study makes it unlikely that non-reproductive individuals aggregate with reproductive ones during their migration towards spawning grounds. Further research is suggested in order to investigate the potential presence of non-reproductive individuals on non-spawning grounds during the reproductive season.

Our objective was to assess SHS exposure among US children and adolescents by using serum cotinine measures to compare those who were exposed to SHS in the home and those without home exposure. We analyzed serum cotinine data from the 2003-2006 National Health and Nutrition Examination Survey for 5518 children (3-11 years) and nonsmoking adolescents (12-19 years). We calculated geometric mean serum cotinine levels by sociodemographic and household characteristics according to self-reported home SHS exposure. Multiple regression analysis was conducted to evaluate independent predictors of serum cotinine levels. Geometric mean serum cotinine levels were 1.05 ng/mL among those with home SHS exposure and 0.05 ng/mL among those without home exposure. Among children who were exposed to SHS at home, serum cotinine levels were inversely associated with age and were similar for non-Hispanic black and non-Hispanic white children. Conversely, among children without SHS exposure at home, serum cotinine levels were higher among non-Hispanic black compared with non-Hispanic white children, and there was no relationship with age. Mexican American children had the lowest level of SHS exposure. Serum cotinine levels were an order of magnitude higher among children with reported SHS exposure at home compared with those with no exposure in the home.

Research paper thumbnail of Analysis of demersal species assemblages from trawl surveys in the South Adriatic sea

A total list of 168 demersal species (fishes, cephalopods and crustaceans) was obtained during the surveys; species abundance data (individuals/trawling hour) were processed according to multivariate techniques in order to describe the composition and the distribution of the main species assemblages within the investigated area (10-800-m bathymetric range). Multivariate analysis of MEDITS survey catch data showed a strong relationship between fish assemblages and depth, while the influence of depth was lower with respect to cephalopod and especially crustacean assemblage distribution. © Ifremer/Cnrs/Inra/Ird/Cemagref/Elsevier, Paris

Trawls were conducted at a bathymetric range of 10-800 m, by the same vessel and same sampling gear in the framework of the E. U. Project, MEDITS. Fifty-two benthic-epibenthic, and nektonic species (three stomatopods, 49 decapods) were caught. Species density data (individuals per km 2 ) were processed according to multivariate techniques to describe the composition and distribution of main species assemblages. The assemblages were consistent throughout the surveyed area with some differences between the western and eastern zones, mostly those found on shelf bottoms. The influence of oceanographic features, other than depth, is discussed.
