  • Patent number: 11961594
    Abstract: A method for identifying two or more infections as related or non-related infections based on an estimated genetic relatedness of the two or more infections, comprising: (i) receiving, for each of two or more infected patients, infection-relevant information comprising an antibiotic resistance profile for the patient's infection, a geo-temporal record for the patient, and a caregiver history for the patient; (ii) estimating, using a trained genetic relatedness model, a genetic relatedness of at least two of the two or more infections; (iii) comparing the estimated genetic relatedness between at least two of the two or more infections to a predetermined threshold; (iv) identifying, based on the comparison, the at least two of the two or more infections as a related infection or a non-related infection.

  • Patent number: 11807895
    Abstract: A method for detecting oncogenic growth and viability, and/or degree of cellular transformation and/or identifying an agent that inhibits cellular transformation is disclosed. The method including: providing a cellular sample, such as a sample of cells obtained from a subject or a cell line; culturing the cellular sample in low attachment conditions; and detecting growth and7or cell viability of the sample, wherein increased growth relative and/or viability relative to a control or control level indicative of basal growth and/or viability indicates cellular transformation. In some embodiments, the method includes introducing a n expression vector into cells of the cellular sample, wherein the expression vector comprises a gene product expression sequence being tested for transformation ability. In some embodiments the cellular sample is contacted with a test agent and growth and/or cell viability of the sample is determined to determine if the agent inhibits transformation.

  • Patent number: 11530440
    Abstract: The present invention relates to methods of quantifying, amplifying, or preparing nucleic acid molecules, where the methods involve contacting a sample to be tested with nucleic acid molecule amplification reaction components and a label to form a reaction sample. The methods further involve partitioning the reaction sample into droplets or a gel and allowing nucleic acid molecule amplification to occur.

  • Publication number: 20200365257
    Abstract: A method and system for predicting the next location for a patient in a healthcare facility, including: defining a location-procedure co-occurrence matrix for the healthcare facility, wherein the location-procedure co-occurrence matrix define the probability that a procedure will be performed in a specific location; defining a procedure transition matrix, wherein the procedure transition matrix defines the probability of moving from a first procedure to a second procedure; defining a patient input vector based upon the patient condition and procedures performed on the patient; calculating an output vector based upon the patient input vector and the procedure transition matrix; producing a procedure vector by setting all values in the output vector to zero except for the N highest values in the output vector, where N is an integer; calculating a location prediction vector based upon the procedure vector and the location-procedure co-occurrence matrix; and transmitting information regarding the M most likely ne
