The purpose of this article is to develop a virtual reality (VR) instructional environment that allows users to visually experience scattered radiation intensity distribution during computed tomography (CT) is presented. Scattered radiation generated during a CT scan of the head was measured with an air dosimeter to create a dose profile. A color map showing the spread and intensity of scattered radiation was created from the dose profile and used to generate VR content. Scattered radiation was visually recognized using the developed VR educational environment. From the results obtained, it is clear that with the developed immersive teaching material, it is possible to visually recognize the characteristics of scattered radiation in head CT examinations. Users can look back on their own radiation protection methods through virtual experiences with the developed immersive teaching materials.

Objective: Illness-related information can be significant for cancer patients after gastrointestinal (GI) surgery in terms of their performing adaptive tasks. This study longitudinally investigated the health outcomes of Japanese patients who read a booklet about cancer patients' problems and adaption tasks and evaluated the association between the responses to the booklet and the patients' health outcomes. Methods: A questionnaire survey about quality of life (QOL), fatigue, anxiety, cognitive plight, and resilience was administered to postoperative patients with GI cancer 1 week after their discharge from hospital and 6 months after surgery. The questionnaires were returned by email. Results: The mean age of the 32 patients at 1 week was 60.9 years; nearly 68.8% of them were men. As a whole, only two variables, QOL and anxiety, were significantly improved at 6 months over those at 1 week. Three statements were taken to gauge the responses to the booklet. In the two-way ANOVA that took QOL and responses to the booklet as independent variables, the post hoc test found that QOL was significantly improved in patients who agreed with the statement “I vaguely understood the content” or “I will deal with my tasks as described in the scenarios” but not in patients who agreed with the statement “The scenarios reflect my situation.” The anxiety in patients who agreed with the statement “The scenarios reflect my situation” was high at both survey points. Conclusions: This study suggests that associations between the responses to the informational booklet and patients' health outcomes partially indicate the directional property of how to support their information usage.

Objective: Postoperative patients with gastrointestinal (GI) cancer have multiple adaptation tasks and care needs to improve their quality of life (QOL). Whether their supportive care needs differ according to their physical and psychosocial conditions is unclear. This study investigated patients' (1) physical and psychosocial conditions (QOL, fatigue, anxiety, cognitive plight, and resilience) and (2) responses to an informational booklet describing cancer patients' problems and adaptation tasks, and examined the association between the two factors. Methods: A questionnaire survey was conducted to postoperative patients with GI cancer. Results: The mean age of the 69 respondents was 63 years; 59.4% of the respondents were men. Nine patients who did not read the booklet showed high fatigue and cognitive plight and low QOL. The patients (36.2%) who chose “I vaguely understood the content” showed low scores for resilience and cognitive plight while those (8.5%) who chose “I will deal with my tasks as described in the scenarios” showed high scores for both of these variables. Conclusions: The condition of some patients continued to be highly affected by their cancer. In terms of understanding the contents of the booklet, resilience was significant, and cognitive plight did not necessarily have a negative impact. The provision of information by means of a booklet might not be suitable for patients who are highly affected by their cancer. Patients may need additional support to be able to make good use of the information provided in such a booklet.

Objective The aim of the present study was to collect data on the characteristics, degree, and natural course of urinary complications, as well as self-care for such complications, in patients during and after prostate intensity-modulated radiation therapy (IMRT). Methods Quality of life data were collected retrospectively for all eligible patients who underwent IMRT. In all eligible patients, urinary symptoms were evaluated using questionnaires and face-to-face interview. Participants were asked to respond to a self-administered questionnaire concerning the core lower urinary tract symptom score during the course of IMRT and up to 12 months after the completion of IMRT. Results In all, 29 eligible patients were included in the study. The frequency of urinary symptoms increased over of the course of IMRT, decreased at ≥3 months after completion of IMRT, and disappeared 6 months after IMRT. Responses to the questionnaire revealed a variety of approaches to self-care and adaptations by patients to manage urinary symptoms. Conclusions During and after IMRT for localized prostate cancer, patients often developed more frequent urination and urgency than at the start of IMRT, and recovered 3-6 months after the completion of IMRT. Based on the present study, clinicians and nurses could help convey this information to patients and thus offer better support.
