Performance Improvement of a Natural Language Processing Tool for Extracting Patient Narratives Related to Medical States From Japanese Pharmaceutical Care Records by Increasing the Amount of Training Data: Natural Language Processing Analysis and Validation Study

Performance Improvement of a Natural Language Processing Tool for Extracting Patient Narratives Related to Medical States From Japanese Pharmaceutical Care Records by Increasing the Amount of Training Data: Natural Language Processing Analysis and Validation Study

Unlike structured databases, such as the Japanese Adverse Drug Reaction Report Database, text data, such as patient narratives, comprising natural language, are often unstructured and ambiguous in meaning. To enable computers to handle and analyze natural languages, appropriate natural language processing (NLP) technology is necessary.

Breast Cancer Screening Participation and Internet Search Activity in a Japanese Population: Decade-Long Time-Series Study

Breast Cancer Screening Participation and Internet Search Activity in a Japanese Population: Decade-Long Time-Series Study

The search term was “nyuugan-kenshin,” which means “breast cancer screening” in Japanese. Monthly RSV data from the Google Trends platform were retrieved on September 17, 2023. Since the Japanese term “nyuugan-kenshin” is written as one continuous word without any spaces, we did not enclose it in quotes when using it in Google Trends. Because Google Trends does not provide a “Topic” option for the Japanese term “nyuugan-kenshin,” we used the “Search Term” option instead.

Changes in Physical Activity Across Cancer Diagnosis and Treatment Based on Smartphone Step Count Data Linked to a Japanese Claims Database: Retrospective Cohort Study

This was a retrospective cohort study analyzing a database provided by De SC Healthcare Inc, in which daily step count data are linked to a Japanese claims database [13,14]. Briefly, members of affiliated health insurance associations can access the Kencom smartphone app, developed by De SC Healthcare Inc, free of charge. Daily step counts were measured using the Kencom app, synchronized with smartphone pedometers [13,14].

Evaluating and Enhancing Japanese Large Language Models for Genetic Counseling Support: Comparative Study of Domain Adaptation and the Development of an Expert-Evaluated Dataset

Evaluating and Enhancing Japanese Large Language Models for Genetic Counseling Support: Comparative Study of Domain Adaptation and the Development of an Expert-Evaluated Dataset

In addition, Sukeda et al [11,12] conducted domain adaptation for the medical fields on several Japanese LLMs. However, there are no studies specifically examining Japanese LLMs’ medical proficiency in genetic counseling. It is crucial not only to measure the general medical capabilities of LLMs through medical examinations but also to have experts evaluate LLMs in specialized tasks within the medical field.

Is Boundary Annotation Necessary? Evaluating Boundary-Free Approaches to Improve Clinical Named Entity Annotation Efficiency: Case Study

This data set comprises 148 open-access case reports in Japanese. Textbox 1 presents an example document from the data set. A case report is a detailed description of a patient’s medical condition, containing, among other information, the temporal progression of the disease and its treatment. Its format is similar to a discharge summary and is frequently used in medical NLP, such as in MIMIC-III [26] or n2c2 shared tasks [27].

Illicit Trade of Prescription Medications Through X (Formerly Twitter) in Japan: Cross-Sectional Study

Illicit Trade of Prescription Medications Through X (Formerly Twitter) in Japan: Cross-Sectional Study

“Okusuri” refers to medications, and “Mogu Mogu” is used as an onomatopoeia for eating or biting in Japanese. This specific term is local in Japan and is unique enough to be distinguished by other transaction keywords in that most of the traded medications are psychiatric prescription medications. Indeed, to assess the unique attributes of illicit trading using this specific term, the Japanese government has recently funded domestic investigative research [27].
