  • Publication number: 20200258639
    Abstract: A computer-implemented method of generating a generalized model for adaptively predicting occurrence or progression of a first adverse health condition for a first subpopulation arbitrarily selected from a total population, includes extracting information about characterizing features of a plurality of second subpopulations, about occurrences and/or severity of the first adverse health condition found therein and/or about corresponding prognostic results, from a plurality of publications. One or more of the characterizing features are associated with corresponding first factors indicating a relation with an adverse or beneficial contribution of the characterizing feature to the occurrence or progression of the first adverse health condition, and with corresponding second factors indicating the relative frequency of occurrence in the respective second subpopulation considered in the respective publication.

  • Patent number: 10172994
    Abstract: The invention relates to a device for hemodiafiltration with an extracorporeal circulation (10) for receiving blood to be purified and having a hemodialyzer and/or hemofilter (20) which is connected to the blood circulation (10), such that the blood circulation (10) has at least one inlet line (12, 14) for the supply of a replacement fluid upstream and downstream from the hemodialyzer and/or hemofilter (20), characterized in that the apparatus also comprises measurement apparatuses for recording the transmembrane pressure and/or hematocrit (HKT) and/or blood density, such that the measurement apparatuses are connected to a control unit (100) for controlling one or more of the transmembrane pressure and/or the hematocrit (HKT) and/or the blood density, the control unit (100) being constructed so that the control is implemented with the help of at least one of the infusion rates (Qspre, Qspost) of the replacement fluid (13, 15), and the blood to be purified is exposed to a high-frequency electromagnetic field a

  • Patent number: 9682181
    Abstract: A dialysis device including a dialysis circuit, a blood circuit; and a dialyzer. The dialysis device includes a device for generating a high-frequency electromagnetic field and a device for generating an electrostatic direct current field. Both devices are designed and arranged in such a way that blood to be treated can be exposed to the high-frequency electromagnetic field and the electrostatic direct current field when passing through the dialyzer.
