Abstract: In accordance with some embodiments of the disclosed subject matter, mechanisms for efficient real-time embedded processing of physiological signals using S transforms are provided. In some embodiments, a system comprises: a sensor configured to monitor at least one condition of the subject and generate physiological feedback data; a processor configured to receive the physiological feedback data from the sensor and programmed to: implement a ECG Leads filter bank with a predetermined number of coefficients and taps selected to perform a Stockwell transform on the physiological feedback data and provide a frequency domain data of the physiological feedback data; analyze the frequency domain data using a physiological monitoring criteria; generate a report about the physiological condition of the subject based on the analysis of the frequency domain data using the physiological monitoring criteria; a display configured to display the report about the physiological condition of the subject.

Abstract: In accordance with some embodiments, systems, methods, and media for estimating compensatory reserve and predicting hemodynamic decompensation using physiological data are provided. In some embodiments, a system for estimating compensatory reserve is provided, the system comprising: a processor programmed to: receive a blood pressure waveform of a subject; generate a first sample of the blood pressure waveform with a first duration; provide the sample as input to a trained CNN that was trained using samples of the first duration from blood pressure waveforms recorded from subjects while decreasing the subject's central blood volume, each sample being associated with a compensatory reserve metric; receive, from the trained CNN, a first compensatory reserve metric based on the first sample; and cause information indicative of remaining compensatory reserve to be presented.

Abstract: Systems and methods that provide magnetically-enhanced delivery of therapeutic agents to selected tissue are disclosed. The systems and methods involve the use of carrier devices and release devices and two different magnetic fields to move magnetic particles into selected tissue. Movement of the magnetic particles (and any associated therapeutic agent) into the tissue may be assisted by both magnetic attractive forces as well as magnetic repulsive forces.

Abstract: This document relates to molecularly imprinted polymers for use in mammals. For example, methods and materials for capturing a molecule in the body of a mammal using a molecularly imprinted polymer are provided. In some cases methods for delivering a molecule using a molecularly imprinted polymer into the body of a mammal are provided. The methods provided can be used to target any molecule in the body of a mammal.

Abstract: A system for tracking and evaluating a colonoscopy procedure performed using an endoscope includes a tracking subsystem, a processing subsystem and a display subsystem. The tracking subsystem provides information representative of the location of the endoscope within a patient's colon during the procedure. The processing subsystem generates visualization metrics from images produced by the endoscope during the procedure. The display subsystem is coupled to the tracking and processing subsystems to generate a visual display of the patient's colon with information representative of the visualization metrics at associated colon locations.

Abstract: This document provides methods and materials related to minimally invasive techniques for reducing the volume of and/or occluding left atrial appendages.

Abstract: A system provides for remote monitoring using asynchronous code division multiple access (CDMA) communication techniques between a base station and one or more transponders. Each transponder is attached or otherwise associated with an object or an environment to be monitored. Upon receipt of an interrogation signal, a transponder generates and transmits a coded transponder signal containing the monitored data. The coded transponder signal is generated using a spreading code. Each transponder is associated with a unique, mutually exclusive set of spreading codes. Each spreading code is based on a unique transponder address and the monitored data to be sent. A detector asynchronously monitors received signals for any of the available spreading codes. Once the detector detects a particular spreading code, the base station can identify the source transponder and extract the monitored data.

Abstract: This document provides methods and materials that can be used to reduce or prevent contrast agent-induced toxicity. For example, devices for capturing contrast agents from blood are provided.
