Systems and methods are provided for non-invasive measurement of endogenous S-nitrosothiols and related measurements thereof. One or more sensors non-invasively measures a set of one or more biometric parameters within a region of interest of a subject to provide a time series of measurements for each of the set of biometric parameters. A medium stores machine-readable instructions that are executable by an associated processor to perform processing comprising receiving the time series of measurements of the biometric parameter, generating, using a predictive model, a value representing an endogenous S-nitrosothiol content of tissue within the region of interest from the time series of measurements of the biometric parameter, and providing, by a user interface, the value representing the endogenous S-nitrosothiol content of tissue within the region of interest to a user.

Methods and apparatuses for monitoring either or both the performance of an orthodontic appliance for repositioning a patient's teeth and/or the user compliance in wearing the appliance using a biosensor. The apparatuses described herein may include one or more sensors, including biosensors, electrical sensors, or both, configured to generate sensor data related to user compliance and/or repositioning of the patient's teeth by an orthodontic appliance.

A vaporization device includes a first portion and a second portion. The first portion includes a first body defining a first interior volume, a first half of a split-pod, a second half of a split-pod, an opening, a first heating apparatus, and a second heating apparatus. The first half of the split-pod is configured to hold a nicotine-containing liquid. The second half of the split-pod is configured to hold a non-nicotine-containing liquid. The opening separates the first half from the second half of the split-pod. The first heating apparatus is dedicated to the first half. The second heating apparatus is dedicated to the second half. The second portion includes a second body defining a second interior volume and a computing system. The computing system is disposed within the second interior volume. The computing system is configured to vary an amount of current supplied to the first and second heating apparatuses.

Disclosed herein are systems and methods for locating and identifying nerves innervating the wall of arteries such as the renal artery. The present invention identifies areas on vessel walls that are innervated with nerves; provides indication on whether energy is delivered accurately to a targeted nerve; and provides immediate post-procedural assessment of the effect of energy delivered to the nerve. The methods includes evaluating a change in physiological parameters after energy is delivered to an arterial wall; and determining the type of nerve that the energy was directed to (sympathetic or parasympathetic or none) based on the evaluated results. The system includes at least a device for delivering energy to the wall of blood vessel; sensors for detecting physiological signals from a subject; and indicators to display results obtained using said method. Also provided are catheters for performing the mapping and ablating functions.

Systems and methods for assessing compliance with position therapy. In an embodiment, position therapy is provided to a user while the user is wearing a position therapy device. The position therapy comprises, by the device, collecting positional data, determining positions of the user over a time period based on the positional data, and, when it is determined that the user is in a target position, providing feedback to the user to influence the user to change to a non-target position. In addition, the device stores a duration of use in its memory. The duration of use indicates a duration that the user has used the wearable position therapy device in each of one or more positions. An assessment of the user's compliance with the position therapy is then provided based, at least in part, on the duration of use.

A method for generating a flow profile of an inhalation device is described. The method comprises the step of measuring acoustic emissions induced by inhalation flow through the inhalation device. The method further comprises the step of detecting peak frequencies in the measured acoustic emissions and generating a flow profile based on the detected peak frequencies. A corresponding device is also described.

A patient health management platform accesses a metabolic profile for a patient and biosignals recorded for the patient during a current time period comprising sensor data and/or lab test data collected for the patient. The platform receives patient data recorded during the current time period comprising food items consumed, medications taken, and symptoms experienced by the patient. The platform implements a machine-learned metabolic model to determine a metabolic state of the patient at a conclusion of the current time period by comparing a true representation of the metabolic state and a prediction of the metabolic state. The true representation and the prediction are determined based on the recorded biosignals and the recorded patient data, respectively. The platform generates a patient-specific treatment recommendation outlining instructions for the patient to improve their metabolic state and provides the patient-specific treatment recommendation to the patient device for display to the patient.

A system and method includes (i) providing patient data stored in a data repository, (ii) applying a first patient identification algorithm to the patient data to identify an initial group of individuals associated with select physical and health characteristics, (iii) applying a second patient identification algorithm to the patient data associated with the initial group of individuals to identify a narrower subgroup associated with select behavioral characteristics, and (iv) generating patient identifiable information from the patient data to allow for notification. The identification of the initial group is based on a determined likelihood of obstructive sleep apnea (OSA) for individuals meeting or exceeding a first threshold criteria. The identification of the narrower group is based on a determined likelihood of long-term adherence to OSA treatment for individuals meeting or exceeding a second threshold criteria. The notification is of designated entities that one or more of the individuals in the narrower subgroup are preferred individuals for OSA.

A method for direct measurement of gradients of patient compliance with a medication regimen by employing a stable non-radioactive isotope taggant compound as part of, bound to, or applied to an endogenous molecule. An assay to determine patient compliance with medication regimens for HIV pre-exposure prophylaxis employing administering a taggant to a pharmacologically active compound, obtaining and collecting a patient tissue or fluid sample analyzing the collected tissue or fluid sample for the taggant concentration and interpreting data from the taggant concentration analysis as an indicator of gradients of patient compliance.

A system and method for patient-adaptive hemodynamic management is described. One embodiment includes a system for hemodynamic management including transfusion, volume resuscitation with intravenous fluids, and medications, utilizing monitored hemodynamic parameters including the described dynamic predictors of fluid responsiveness, and including an intelligent algorithm capable of adaptation of the function of the device to specific patients.
