  • Publication number: 20240079092
    Abstract: Systems and methods for subject clinical condition evaluation using a plurality of modules are provided. Modules comprise features whose corresponding feature values associate with an absence, presence or stage of phenotypes associated with the clinical condition. A first dataset is obtained having feature values, acquired through a first technical background from respective subjects in transcriptomic, proteomic, or metabolomic form, for at least a first of the plurality of modules. A second training dataset is obtained having feature values, acquired through a technical background other than the first technical background, from training subjects of the second dataset, in the same form as for the first dataset, of at least the first module. Inter-dataset batch effects are removed by co-normalizing feature values across the training datasets, thereby calculating co-normalized feature values used to train a classifier for clinical condition evaluation of the test subject.

  • Publication number: 20230323485
    Abstract: This disclosure provides a gene expression-based method for determining a virally-infected subject's risk of developing severe symptoms. In some embodiments, the method may comprise measuring the amount of RNA transcripts encoded by at least two genes in a sample of RNA obtained from the subject, to obtain gene expression data; and based on the gene expression data, providing a report indicating the subject's risk of developing severe symptoms. Kits and methods of treatment are also provided.

  • Patent number: 11768208
    Abstract: Aspects of the present invention include methods for determining a transplant category of a subject having a transplant. Common mechanisms of rejection injury are uncovered across different tissue transplants, and provide a means to understand rational drug design. Various sources of tissues are examined form the patient for understanding AR mechanism (graft biopsy), as well as monitoring by minimal invasive means (blood) or non-invasive means (urine for the kidney allograft). For biomarker discovery different categories of markers are examined such as genes, proteins, peptides and antibodies. These biomarkers can help determine the subject's transplant category (e.g., acute allograft rejection (AR), stable allograft (STA), BK viremia, BK nephritis, drug toxicity or chronic allograft injury (CAI), and the like). Also provided are compositions, systems, kits and computer program products that find use in practicing the subject methods. The methods and compositions find use in a variety of applications.

  • Publication number: 20230227911
    Abstract: Methods for diagnosis of sepsis are disclosed. In particular, the invention relates to the use of bio -markers for aiding diagnosis, prognosis, and treatment of sepsis, and to a panel of biomarkers that can be used to distinguish sepsis from noninfectious sources of inflammation, such as caused by traumatic injury, surgery, autoimmune disease, thrombosis, or systemic inflammatory response syndrome (SIRS).

  • Publication number: 20230160014
    Abstract: This disclosure provides a gene expression-based method for determining whether a subject having sepsis has an Inflammopathic phenotype, an Adaptive phenotype or a Coagulopathic phenotype. A kit for performing the method is also provided.

  • Patent number: 11413280
    Abstract: The present invention provides methods for treatment or prevention of pulmonary hypertension and emphysema using agents that increase activity of FHIT, such as Enzastaurin. Included are methods for using levels of FHIT and/or BMPR2, and checking for mutations in FHIT and/or BMPR2, to select patients for treatment or to monitor effectiveness of treatment. The invention is based on evidence that Enzastaurin prevents and reverses pulmonary hypertension induced in animal model systems, and that it acts by up-regulation of FHIT and/or BMPR2.
