    This study was conducted to develop a Japanese version of a decision aid (DA) for prostate cancer and to provide it in video format. We investigated overseas DAs such as those developed by AHRQ, NICE, and MCC, and collaborated with urologists to select content appropriate for the Japanese healthcare system.Next, based on the MCC version of the DA, we established a video structure including robot-assisted surgery footage under the supervision of urologists and radiation oncologists, and examined the creation process in accordance with international standards (IPDAS).Based on the above, the DA content was finalized and revised with consideration for Japan's treatment realities and expression considerations, and videos were created. After final verification and evaluation by experts, content revisions were implemented, and preparations for viewing devices and outpatient workflow were considered for clinical implementation.

    In medical research involving human subjects, ethical issues exist because medical professionals who are close to the weak become "researchers," and it is necessary to implement ethical education assuming that patients will be research subjects. This research aims to cultivate skills and attitudes toward research subjects, and the ultimate goal is to create and implement a scenario learning program in which "explanation of research in a simulated environment and consent" are given to simulated subjects who are patients.
    In terms of training simulated subjects and curriculum development, a simulated subject training trial course has been held since 2024, but it has been found that building trust and providing feedback to researchers is difficult. We plan to continue holding research on research ethics practitioner training courses in graduate school classes in the future.

    Patient safety is a global priority, and promoting patient engagement is one of the seven strategic goals of the World Health Organization's initiative to maximize the reduction of preventable harm from unsafe care on a global scale. To achieve patient engagement, it is important for patients and their families to play a role as members of the healthcare team, and an essential element is psychological safety. In this study, I focused on the psychological safety of patients and their families in the healthcare team, developed a questionnaire, tested its reliability and validity, and developed a four-factor, 22-item scale. It was found that patients themselves recognized errors and problems during their hospitalization and hospital visits 5.8% of the time and preventable errors 56.7% of the time.

  • Evaluation of physical activity using smartphones and wearable devices in healthcare: Current situation and future perspectives Reviewed

    Abstract With the growing popularity of mobile health (mHealth) devices, including smartphones and wearable devices, information and communications technology has gained high importance in healthcare settings. This study aimed to summarize the current trends in physical activity research wherein mHealth devices are used and provide perspectives for future research. Until recently, questionnaire surveys were primarily used to evaluate physical activity. While questionnaire surveys are effective for subjective evaluation, the use of mHealth devices enables large-scale, real-time, objective evaluation of physical activity. In addition, mHealth devices automatically collect and aggregate data. This allows researchers to perform retrospective analysis of a wide range of indicators of physical activity and health. Particularly, the use of smartphones is highly likely to contribute to large-scale monitoring and health interventions because of their ubiquity. Even though there are fewer users of wearable devices (wrist-worn devices) than those of smartphones, using wearable devices allows for the evaluation of 24-hour movement patterns. The use of wearable devices helps perform further precise analysis that focuses not only on the total amount of physical activity but also on the quality, including measures of intensity, duration, frequency, type, and time. Moreover, some wrist-worn devices measure physiological information such as heart rate and may also provide location information. Combining such data with information from an accelerometer associated with a device may allow for further specific and detailed evaluation of physical activity. The validity of physical activity assessment using major mHealth devices has been confirmed in several studies and is comparable to that of pedometers and accelerometers developed for research purposes. Evaluation of physical activity using mHealth devices involves issues related to the representativeness of the target population and continuity of data, as well as the need for ethical considerations based on privacy policies. While mHealth devices may be used by individuals as a health management tool, it is also expected that the evaluation of physical activity using mHealth devices will be performed in various settings such as epidemiological and clinical studies on physical activity, as well as community services wherein indicators of physical activity are used.

    Novel coronavirus (SARS-Coronavirus-2:SARS-CoV-2) which emerged in Wuhan, China, has spread to multiple countries rapidly. We report the first case of meningitis associated with SARS-CoV-2 who was brought in by ambulance due to a convulsion accompanied by unconsciousness. He had never been to any foreign countries. He felt generalized fatigue and fever (day 1). He saw doctors nearby twice (day 2 and 5) and was prescribed Laninamivir and antipyretic agents, His family visited his home and found that he was unconsciousness and lying on the floor in his vomit. He was immediately transported to this hospital by ambulance (day 9). Under emergency transport, he had transient generalized seizures that lasted about a minute. He had obvious neck stiffness. The specific SARS-CoV-2 RNA was not detected in the nasopharyngeal swab but was detected in a CSF. Anti- HSV 1 and varicella-zoster IgM antibodies were not detected in serum samples. A brain MRI showed hyperintensity along the wall of right lateral ventricle and hyperintense signal changes in the right mesial temporal lobe and hippocampus, suggesting the possibility of SARS-CoV-2 meningitis. This case warns the physicians of patients who have CNS symptoms.
