Antithrombin Population Pharmacokinetics in Pediatric Ventricular Assist Device Patients.

OBJECTIVES: Describe the pharmacokinetics of antithrombin in pediatric patients undergoing ventricular assist device therapy and provide dosing recommendations for antithrombin in this population. DESIGN: A retrospective population pharmacokinetic study was designed. SETTING: Large tertiary care children\u27s hospital Subject inclusion criteria consisted of less than 19 years old. PATIENTS: Subjects less than 19 years old undergoing therapy with a HeartWare ventricular assist device (HeartWare, Framingham, MA) or Berlin EXCOR ventricular assist device (Berlin GmbH, Berlin, Germany), who received a dose of antithrombin with a postdose antithrombin activity level from January 1, 2011, to June 30, 2017. INTERVENTIONS: Population pharmacokinetic analysis and simulation using NONMEM v.7.4 (Icon, PLC, Dublin, Ireland). MEASUREMENTS AND MAIN RESULTS: A total of 41 patients met study criteria (median age, 5.8 years [interquartile range, 1.6-9.9 yr]), and 53.7% underwent therapy with the pulsatile Berlin EXCOR pediatric ventricular assist device (Berlin Heart GmbH, Berlin, Germany). All patients received unfractionated heparin continuous infusion at a mean ± SD dose of 29 ± 14 U/kg/hr. A total of 181 antithrombin doses (44.1 ± 24.6 U/kg/dose) were included, and baseline antithrombin activity levels were 77 ± 12 U/dL. Antithrombin activity levels were drawn a median 19.9 hours (interquartile range, 8.8-41.6 hr) after antithrombin dose. A one-compartment proportional error model best fit the data, with allometric scaling of fat-free mass providing a better model fit than actual body weight. Unfractionated heparin and baseline antithrombin were identified as significant covariates. A 50 U/kg dose of antithrombin had a simulated half-life 13.2 ± 6.6 hours. CONCLUSIONS: Antithrombin should be dosed on fat-free mass in pediatric ventricular assist device patients. Unfractionated heparin dose and baseline antithrombin activity level should be considered when dosing antithrombin in pediatric ventricular assist device patients

The art of face-saving and culture-changing: sculpting Chinese football’s past, present and future

In this paper, we consider the football statues of China, whose football team has dramatically underperformed relative to its population size and economic power. Although China lacks a participative grassroots football culture and has struggled to establish a credible domestic league, recent government intervention and investment has seen football’s profile rise dramatically. China’s many football statues are largely atypical in comparison to the rest of the world, including their depiction of anonymous figures rather than national or local heroes, the incorporation of tackling scenes in their designs, and their location at training camps. Through four specific examples and reference to a global database, we illustrate how these statues reflect the tensions and difficulties inherent in China’s desire to integrate itself into global football, and achieve its stated goal of hosting and winning the FIFA World Cup, whilst simultaneously upholding national, cultural and political values such as the primacy of hard work and learning, and saving face in defeat

EL LEGADO DE KOIZUMI: LA ECONOMÍA SANEADA Y UN NUEVO MODELO DE LIDERAZGO EN JAPÓN

Cinco años después de asumir como primer ministro de una economía estancada, Junichiro Koizumi se prepara para dejar como legado un país diferente. Japón, una ex estrella económica que lamentaba su decreciente influencia internacional, se ha transformado en una sorprendente historia de recuperación. Los rascacielos y centros comerciales que surgen por todos lados son testigos de ello.legado de Koizumi, economia, modelo de liderazgo, Japon

The GEOTRACES Intermediate Data Product 2017 (IDP2017) is the second publicly available data product of the international GEOTRACES programme, and contains data measured and quality controlled before the end of 2016. The IDP2017 includes data from the Atlantic, Pacific, Arctic, Southern and Indian oceans, with about twice the data volume of the previous IDP2014. For the first time, the IDP2017 contains data for a large suite of biogeochemical parameters as well as aerosol and rain data characterising atmospheric trace element and isotope (TEI) sources. The TEI data in the IDP2017 are quality controlled by careful assessment of intercalibration results and multi-laboratory data comparisons at crossover stations. The IDP2017 consists of two parts: (1) a compilation of digital data for more than 450 TEIs as well as standard hydrographic parameters, and (2) the eGEOTRACES Electronic Atlas providing an on-line atlas that includes more than 590 section plots and 130 animated 3D scenes. The digital data are provided in several formats, including ASCII, Excel spreadsheet, netCDF, and Ocean Data View collection. Users can download the full data packages or make their own custom selections with a new on-line data extraction service. In addition to the actual data values, the IDP2017 also contains data quality flags and 1-σ data error values where available. Quality flags and error values are useful for data filtering and for statistical analysis. Metadata about data originators, analytical methods and original publications related to the data are linked in an easily accessible way. The eGEOTRACES Electronic Atlas is the visual representation of the IDP2017 as section plots and rotating 3D scenes. The basin-wide 3D scenes combine data from many cruises and provide quick overviews of large-scale tracer distributions. These 3D scenes provide geographical and bathymetric context that is crucial for the interpretation and assessment of tracer plumes near ocean margins or along ridges. The IDP2017 is the result of a truly international effort involving 326 researchers from 25 countries. This publication provides the critical reference for unpublished data, as well as for studies that make use of a large cross-section of data from the IDP2017.
