Objective: Almost half of all patients with cancer experience dyspnea, which can have various causes. Although systemic corticosteroids are administered to relieve symptoms, their efficacy has not been established. This systematic review aims to determine the efficacy of systemic corticosteroids for dyspnea in patients with cancer. Methods: CENTRAL, MEDLINE, EMBASE, and Ichushi-Web databases were searched for articles published from their inception to September 23, 2019, on studies of systemic corticosteroid administration for dyspnea in patients with cancer. The primary outcome measure was dyspnea intensity, as assessed by patient-reported outcomes. Secondary outcome measures were quality of life, delirium, and severe adverse events. Results: Two RCTs were included in the meta-analysis. With regard to alleviating dyspnea, the systematic corticosteroid group was associated with significantly greater dyspnea relief than the placebo group (mean difference: −0.71 [95% CI: −1.4 to −0.03]). However, a meta-analysis of quality of life and delirium could not be performed due to insufficient data. Analysis of severe adverse events showed no significant difference in their incidence between the corticosteroid and control groups (relative rate: 0.96 [95% CI: 0.19-4.93]). Conclusions: Systemic corticosteroids may be effective in treating dyspnea in patients with cancer, particularly those with lung involvement. Limiting the conditions for which corticosteroids are approved is expected to promote their appropriate use and minimize their adverse effects. However, further investigation is needed to determine the appropriate dosage, and the conditions in which corticosteroids are effective.

Objective: With the Internet serving as a major source of medical information, the abundance of pharmaceutical content across media and digital platforms raises concerns about the impact of inappropriate or misleading information on public health. This study aimed to develop a comprehensive, practical evaluation indicator to assess the reliability and quality of pharmaceutical websites, targeting general consumers in Japan.Methods: We systematically reviewed existing domestic and international criteria for health information quality to develop evaluation indicators. Based on this review, a preliminary set of indicators was drafted and refined using a modified Delphi process involving six experts in pharmaceutical and medical communications. This process incorporated established frameworks, including the Health on the Net (HON) Code, JAMA Benchmarks, and the Japanese eHealth Ethics Code. A validated set of indicators was finalized after four iterative rounds of review and feedback.Results: The final tool comprises 16 evaluation items across three categories: (1) Screening Criteria (4 items), which eliminate websites with misleading content, public indecency, or political/religious affiliations; (2) Website Evaluation Criteria (5 items), assessing operational transparency, contact availability, advertisement distinction, and policy disclosure; and (3) Content Evaluation Criteria (7 items), addressing clarity, accuracy, update frequency, source citation, legal compliance, and balanced risk-benefit information. Each item was rated using a primarily binary (yes/no) scale with intermediate options, such as “partially applicable” or “not applicable.” The tool reflects expert consensus and complies with Japan’s ethical and regulatory standards.Conclusion: This tool facilitates the appropriate dissemination of pharmaceutical information and supports users in identifying trustworthy sources. By explicitly incorporating legal compliance and editorial transparency as evaluation criteria, it encourages higher standards among healthcare professionals and information providers, potentially improving the quality of pharmaceutical communication.

In the new Model Core Curriculum, the objective stated is to "understand the importance of medical research for the advancement of medicine and medical care, and support innovation in medicine through involvement in academic and research activities, developing one's scientific thinking skills." Importantly, scientific background and researcher training education, such as laboratory assignments, are clearly positioned in the Model Core Curriculum and are available to all students. The curriculum consists of five components : Developing a research mindset, Understanding established theories, Conducting Research, Publishing Research, and Research Ethics. In addition, laboratory experience and practical training in basic medicine were also added to the description. Further policy and financial support for researchers will be necessary to increase the number of basic medical researchers in the future.

Objective: To evaluate the efficacy of high-flow nasal cannula oxygen (HFNC) for dyspnea in patients with advanced disease. Methods: A literature search was conducted using MEDLINE, Cochrane Library, EMBASE, and Ichu-shi Web. Inclusion criteria were: 1) randomized controlled trials evaluating the effect of HFNC on dyspnea; 2) aged 18 years or older with advanced disease with hypoxemia; 3) control group was conventional oxygen therapy or noninvasive positive pressure ventilation. Exclusion criteria were: 1) patients in intensive care unit, 2) weaning from ventilator. Results: Six studies (4 from database searches, and 2 from hand searches) were included. In the 2 studies evaluating short-term intervention, one showed HFNC was more efficacious, and the other conventional oxygen was more efficacious. In the 2 studies evaluating long-term interventions: one showed HFNC was more efficacious, and the other showed no significant difference. In the 2 studies evaluating the intervention during exercise, one showed HFNC was more efficacious, and the other showed no significant difference. Conclusion: HFNC may be effective for dyspnea in patients with advanced disease associated with hypoxemia.

BACKGROUND/OBJECTIVES: The level of serum albumin is an index of nourishment care and management. However, the distribution and correlates of serum albumin levels among individuals with motor disorders have not been reported until now. Therefore, we examined the distribution and correlates of serum albumin levels among individuals with motor disorders. SUBJECTS/METHODS: A cross-sectional study on 249 individuals with motor disabilities (144 men, mean age: 51.4 years; 105 women, mean age: 51.4 years) was conducted at five institutions in Ibaraki Prefecture, Japan in 2008. The results were compared with data from the National Health and Nutrition Survey. RESULTS: The mean serum albumin levels were 4.0 ± 0.4 g/dL for men and 3.8 ± 0.5 g/dL for women. Overall, 17 (11.8%) men and 25 (23.8%) women had hypoalbuminemia (serum albumin level ≤ 3.5 g/dL); these proportions were greater than those among healthy Japanese adults (≤ 1%). Low serum albumin level was related with female sex, older age, low calf circumference, low relative daily energy intake, low hemoglobin (Hb), low blood platelet count, low high-density lipoprotein cholesterol (HDL-C), low HbA1c, and high C-reactive protein (CRP) levels. The strongest correlates, based on standardized betas, were Hb (0.321), CRP (-0.279), and HDL-C (0.279) levels. CONCLUSIONS: These results indicate that the prevalence of hypoalbuminemia is higher in individuals with motor disabilities than in healthy individuals and that inflammation is a strong negative correlate of serum albumin levels. Therefore, inflammation should be examined for the assessment of hypoalbuminemia among institutionalized individuals with motor disabilities.

Introduction: No formal curriculum has been formulated for teaching behavioral science to undergraduate medical students in Japan.
Method: We conducted a survey using the Delphi method to investigate the required competency in behavioral science for graduates in medicine. Then, we developed an outcome-oriented curriculum for teaching behavioral science.
Results: We propose an educational module of behavioral science consisting of 15 sessions of 90-minute lectures, small group discussions, and practice.
Discussion: We recommend including not only lectures but also practices according to problem-based learning as well as team-based learning in the curriculum to achieve the target outcome.

In enabling consumers to make thetr own judgments regarding the risks of drugs, it is essntial to share information regarding the risks of drugs among stakeholders (governmental agencies, pharmaceutical companies, healthcare professionals and consumers or patients) and to have communication (risk communication).In particular, the communication between governmental agencies and consumers or patients is given a high priority. Hence, its provisions and strategies should be considered thoroughly.
FDA's risk communication efforts are part of a larger drug safety initiative that began in November 2004. In fact, FDA is engaged in verification and strategies aiming at strengthening drug safety. As a part of these efforts, FDA has published the "Guidance Drug Safety Information-FDA's Communication to the Public" and "FDA Strategic Plan for Risk Communication".
In this article, we present the "FDA Strategic Plan for Risk Communication" translated into Japanese and explain the situation of risk communication for drugs from the FDA perspective. We also examine the future of risk communication in Japan.

EBM is the integration of best research evidence with clinical expertise and patient values. EBM has been extending to “evidence-based healthcare/practice” with wider perspectives. When considering healthcare-related evidence, it is useful to distinguish three aspects. Namely, they are “create”, “communicate”and “utilize”. At first, “clinical questions” are generated in real clinical settings. To create clinical evidence, “clinical questions” need to be refined as “research questions”. Concerning the aspect of communication, there are lots of proposals and statements to improve the reporting of research findings. The Uniform Requirements for Manuscripts Submitted to Biomedical Journals proposed by the International Committee of Medical Journal Editors has been evolved since 1979 and has become the global standard for scientific authors and editors. Concerning the aspect of “utilize”, there are two problems, that is, overuse and underuse of evidence. The former is related with the problem of evidence-practice gap. Appropriate use of clinical practice guidelines are expected to reduce these gaps. The latter is linked with the confusion that evidence equals EBM. Evidence is merely evidence even if the level is high in scientific and general meaning. When clinicians make individual decisions, they are required to do them comprehensively balancing the three factors such as evidence, value and resource.

The promotion of clinical research in Japan requires the establishment of a formal and systematic education and training program for clinicians to ensure they become effective clinician investigators. The first of its kind in Japan, a formal 1-year masters-degree-level training program (MCR course) was started at Kyoto University School of Medicine and Public Health. The first 28 students graduated in 2008, with most returning to their original clinical institutions.
1) As follow-up, we conducted a self-administered questionnaire survey of all 28 graduates (response rate, 86%) concerning the current status of clinical research and problems encountered at their institutions.
2) Almost 40% of respondents (n=24) reported "no time" or "no research collaborators" for clinical research.
3) Twenty respondents (83%) have attempted to promote clinical research at their hospital or workplace, but only 1 has received institutional support.
4) Over half of the respondents (54%) would like to be working in both clinical research and clinical practice at their hospital in the future (10-year timescale). Forty-two percent of respondents had a concrete image of the clinical researcher's career path.
5) Although open to improvement, the MCR program presents a concrete model for the education of clinical researchers. These findings suggest that promoting the conduct of clinical research requires the implementation of a support system and adjustment of personal and physical infrastructure.
