  • Publication number: 20210241178
    Abstract: Embodiments discussed herein facilitate determination of risk of relapse of AML post-transplant. One example embodiment is a method, comprising: accessing a digital whole slide image (WSI) comprising a post-transplant bone marrow aspirate from a patient that has acute myeloid leukemia (AML); segmenting one or more myeloblasts on the digital WSI; extracting one or more features from the segmented one or more myeloblasts; providing the one or more features extracted from the segmented one or more myeloblasts to a trained machine learning model; and receiving, from the trained machine learning model, an indication of a risk of relapse of the AML.

  • Patent number: 10234462
    Abstract: The disclosure relates to assessing heart failure in vitro by measuring the concentration of the marker mimecan in a sample, and optionally measuring in the sample the concentration of one or more other marker(s) of heart failure, and of assessing heart failure by comparing the concentration of mimecan and the one or more other marker(s) to reference concentrations of this (or these) marker(s) as established in a reference population. The one or more markers may be selected from the group comprising a natriuretic peptide marker, a cardiac troponin marker, and a marker of inflammation. Also disclosed are the use of mimecan as a marker protein in the assessment of heart failure, a marker combination comprising mimecan, and a kit for measuring mimecan.

  • Publication number: 20160146836
    Abstract: The invention relates to a method for assessing heart failure in vitro comprising the steps of measuring in a sample the concentration of the marker CRYAB, of optionally measuring in the sample the concentration of one or more other marker(s) of heart failure selected from the group consisting of a natriuretic peptide marker, a cardiac troponin marker, and a marker of inflammation, and of assessing heart failure by comparing the concentration determined in for CRYAB and the concentration(s) determined for the optionally one or more other marker to the concentration of this marker or these markers as established in a reference population. Also disclosed are the use of CRYAB as a marker protein in the assessment of heart failure, a marker combination comprising CRYAB and a kit for measuring CRYAB.

  • Publication number: 20140193845
    Abstract: Disclosed is a method for assessing heart failure in vitro including the steps of measuring in a sample the concentration of the marker SFRP-3, of optionally measuring in the sample the concentration of one or more other marker(s) of heart failure, and of assessing heart failure by comparing the concentration determined in for SFRP-3 and the concentration(s) determined for the optionally one or more other marker to the concentration of this marker or these markers as established in a reference population. Also disclosed are the use of SFRP-3 as a marker protein in the assessment of heart failure, a marker combination comprising SFRP-3 and a kit for measuring SFRP-3.
