Objectives: N-terminal pro brain natriuretic peptide (NT-proBNP) is a biomarker for myocardial stress that is used in diagnosing and prognosticating heart failure (HF). However, its interpretation is complicated by clinical factors. This study aims to clarify the prognostic value of NT-proBNP in patients with heart failure with preserved ejection fraction (HFpEF), and risk-prediction cutoffs considering various clinical factors.

This study investigated the association between the use of β-blockers and prognosis in hospitalized HF patients with and without AF in Japan. Patients hospitalized with the first episode of acute HF were identified from the National Database of Health Insurance Claims and Specific Health Checkups of Japan between April 2014 and March 2021.

Invasive examinations for CMD detection are difficult in older patients with HFpEF, and the decision criteria for noninvasive CMD measurements are unclear. We aimed to identify alternative factors in the possible involvement of CMD in the progression and prognosis of HFpEF.

Radiology reports are an essential communication method for ensuring smooth workflow in healthcare. However, many of these reports are described in free text, and findings documented by radiologists may not be adequately addressed. In this study, focusing on pulmonary nodules, we evaluated whether cases in which radiologists described follow-up as recommended were receiving appropriate treatment.

Aromatherapy may reduce these adverse events by enhancing parasympathetic nervous activity (PNA). However, the effects of aromatherapy during exercise remain relatively unknown.

With the introduction of transformer-based language models, such as bidirectional encoder representations from transformers (BERT), the performance of information extraction from free text has improved significantly in both the general and medical domains. However, it is difficult to train specific BERT models to perform well in domains for which few databases of a high quality and large size are publicly available.

The response data are sent to and stored as structured data on the server in hospital information system, and could be converted to Japanese and quoted as part of progress notes in the electronic medical record.

A radiology report is prepared for communicating clinical information about observed abnormal structures and clinically important findings with referring clinicians. However, such observations and findings are often accompanied by ambiguous expressions, which can prevent clinicians from accurately interpreting the content of reports. To systematically assess the degree of diagnostic certainty for each observation and finding in a report, we defined an ordinal scale comprising five classes: definite, likely, may represent, unlikely, and denial.

Some multicenter clinical studies require the acquisition of clinical specimens from patients, and the centralized management and analysis of clinical specimens at a research institution. In such cases, it is necessary to manage clinical specimens with anonymized patient information. In addition, clinical specimens need to be managed in connection with clinical information in clinical studies.
View Article and Find Full Text PDFBackground: Radiology reports are usually written in a free-text format, which makes it challenging to reuse the reports.
Objective: For secondary use, we developed a 2-stage deep learning system for extracting clinical information and converting it into a structured format.
Methods: Our system mainly consists of 2 deep learning modules: entity extraction and relation extraction.
Background: Documentation tasks comprise a large percentage of nurses' workloads. Nursing records were partially based on a report from the patient. However, it is not a verbatim transcription of the patient's complaints but a type of medical record.
