Abstract: This application provide a satellite message transmission method, a system, and a terminal device, so that an identifier of a satellite message may be indicated in the satellite message, and occupation of space may be reduced. The identifier of the satellite message may facilitate association of relationships among a plurality of messages. In the method, a first terminal device generates an identifier of a satellite message based on timestamp information in response to an operation indicating to send the satellite message, and then sends the identifier of the satellite message together with message content of the satellite message. Compared with generating the identifier of the satellite message by using a general technology, generating the identifier of the satellite message based on the timestamp information may occupy less space.

Abstract: 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.
