  • Patent number: 9968283
    Abstract: A method and related system to, among other things, automatically infer answers to all of the ADL questions and the first four questions of the IADL in the home. The inference methods detect the relevant activities unobtrusively, continuously, accurately, objectively, quantifiably and without relying on the patient's own memory (which may be fading due to aging or an existing health condition, such as Traumatic Brain Injury (TBI)) or on a caregiver's subjective report. The methods rely on the judicious placement of a number of sensors in the subject's place of residence, including motion detection sensors in every room, the decomposition of each relevant activity into the sub-tasks involved, identification of additional sensors required to detect the relevant sub-tasks and spatial-temporal conditions between the signals of sensors to formulate the rules that will detect the occurrence of the specific activities of interest.

  • Patent number: 9708664
    Abstract: It was determined whether SNPs in SLC4A5 are associated with salt sensitivity of blood pressure (BP). Subjects consumed an isocaloric constant diet with a randomized order of 7 days low Na+ (10 mmol/d) and 7 days high Na+ (300 mmol/d) intake. Salt sensitivity was defined as a ?7 mm Hg increase in mean arterial pressure (MAP). 35 polymorphisms in 17 candidate genes were assayed. Association analyses with salt sensitivity revealed three variants that associated with salt sensitivity, two in SLC4A5 (rs7571842, rs10177833; P<0.001), and one in GRK4 (rs1801058; P=0.020). Paradoxical changes in blood pressure in response to changes in salt intake were also found associated with a SNP for DRD2 (rs6276). In conclusion, SLC4A5 variants are strongly associated with salt sensitivity of BP in Caucasian and a DRD2 SNP is a marker for paradoxical response to salt intake.

  • Publication number: 20150005290
    Abstract: To characterize the urinary exosome miRNome, microarrays were used to identify the miRNA spectrum present within urinary exosomes from ten individuals that were previously classified for their salt sensitivity status. The present application discloses distinct patterns of selected exosomal miRNA expression that were different between salt-sensitive (SS), salt-resistant (SR), and inverse salt-sensitive (ISS) individuals. These miRNAs can be useful as biomarkers either individually or as panels comprising multiple miRNAs. The present invention provides compositions and methods for identifying, diagnosing, monitoring, and treating subjects with salt sensitivity of blood pressure. The applications discloses panels of miRNAs useful for comparing profiles, and in some cases one or more of the miRNAs in a panel can be used. The miRNAs useful for distinguishing SS and SR or ISS and SR subjects. One or more of the 45 miRNAs can be used. Some of the miRNAs have not been previously reported to be circulating.

  • Patent number: 8551026
    Abstract: The gait monitor system and method provides various basic gait parameters including step count, cadence, and step duration, in addition to its ability to distinguish between normal, limping and shuffling gait modes, as well as determine falls. Moreover, this gait monitor may be provided with additional sensors, e.g. beam break at the beginning and end of a corridor to estimate average walking velocity (with the distance between the beams known or determined); this enables the calculation of additional gait characteristics such as average step length and average stride length. These parameters can additionally be used to detect various gait anomalies and other diagnostic information.

  • Publication number: 20110087113
    Abstract: A system and method for detecting, monitoring and analyzing physiological characteristics. Signals from a subject are acquired from a suite of sensors, such as temperature, carbon dioxide, humidity, light, movement, electromagnetic and vibration sensors, in a passive, non-invasive manner. The signals are processed and physiological characteristics are isolated for analysis. The system and method are to analyze sleep patterns, as well as to prevent bed sores or detect conditions such as illness, restless leg syndrome, periodic leg movement, sleep walking, or sleep apnea. However, numerous other applications of the invention are also disclosed.
