Abstract: An information processing device used in a system that predicts a prognosis of a patient by machine learning, the information processing device including: an input unit that receives an input of a plurality of sets of time-series data corresponding to a plurality of patients, the time-series data including a plurality of first parameters related to at least one of a condition and a treatment of each of the patients; and a processing unit that calculates an acquisition rate and an acquisition frequency of each of the first parameters included in the plurality of sets of time-series data, and selects a second parameter to be used for training data from the plurality of first parameters by using at least one of the calculated acquisition rate and the calculated acquisition frequency.

Abstract: A medical information processing method that is executed by a processor, and includes: acquiring event information registered in a medical information system and including a patient identifier (ID), the patient ID including identification information on a patient, identification information on an event, and first temporal information indicating occurrence time of the event; acquiring, by using the patient ID and the first temporal information, first medical care information including second temporal information with a temporal resolution higher than that of the first temporal information related to the patient; and estimating, based on the first medical care information, the occurrence time of the event with the temporal resolution higher than that of the first temporal information.

Abstract: A guide wire capable of exhibiting improved penetrability for penetrating a stenosis without degradation of passing performance of the guide wire. A guide wire includes a wire main body formed into a linear shape, a distal end portion of the wire main body is formed into a curved shape by a top portion that forms an extreme distal portion and a surrounding portion that makes the top portion continuous with a peripheral surface of the wire main body, a plurality of recesses are formed in the distal end portion, and the recesses are formed in the top portion and the surrounding portion, respectively.

Abstract: A guide wire has an elongated core portion, a resin coating layer including a resin material and covering a distal portion of the core portion, and a metallic tubular member that has a lumen into which the core portion is inserted, and that is disposed so as to be in contact with at least a portion of a proximal end of the resin coating layer. The tubular member is formed in a state where the lumen is reduced in diameter by cold forging, and at least a portion of an inner surface forming the lumen has a compressive bonding surface which is compressively bonded to an outer surface of the core portion.
