BACKGROUND: physicians' awareness regarding evidence-based medicine (EBM), clinical practice guidelines, and clinical information resources were rarely examined in Japan. We need to know them prior to the initiation of the Medical Information Network Distribution Service (Minds) by the Japan Council for Quality Health Care (JCQHC) .
METHODS: A total of 10, 000 directors/owners of private clinics (CDs: clinic physicians) affiliated with the Japan Medical Association (JMA) and 8682 physicians working for hospitals certified by the JCQHC (HDs: hospital physicians) were randomly selected and surveyed by a mailed questionnaire.
RESULTS: The response rate to the questionnaire was 18.7% (n=1865) among CDs and 67.8% (n=5885) among HDs. The percentage of respondents who uses internet was 39.9% among CDs and 69.3% among HDs. The information resource most commonly used by all respondents was medical journals, followed by textbooks. The percentage of respondents who used medical literature database was 10.8% among CDs and 49.7% among HDs, respectively. Approximately 80% of all respondents approved implementing EBM in daily practice. Fifty percent of all respondents indicated to have used clinical practice guidelines, and 90% of all the guideline users replied that clinical practice guidelines are useful tools for clinical decision-making. Over half of HDs required to access to the abstracts of the literature cited in the guidelines.
CONCLUSIONS: Many physicians who responded to the survey acknowledged that EBM will contribute to improving the quality of medical services. They are positive in using clinical practice guidelines that include a series of recommendations proposed by specialists in the relevant field (s) in accordance to the reviewed evidence.

BACKGROUND: The purpose of our study was to compare the characteristics of medical practitioners who prefer using the Internet as their information resource and those who prefer using printed materials.
METHODS: From December 2002 to January 2003, a non-anonymous questionnaire was sent out by post to members of the Japanese Medical Association (JMA) and physicians working in hospitals. Contributing factors were examined by using logistic regression analysis.
RESULTS: The response rates for the questionnaires were 18.7% (n=1868) for JMA physicians and 68.0% (n=5901) for hospital physicians. Factors associated with the preference for using the Internet were: ‘younger age’; ‘use of the Internet to solve clinical problems and uncertainties’; ‘use of personal computers at work’; and, ‘use of personal computers at home’.
CONCLUSION: The results of this study show that, although some younger physicians prefer printed materials, providing medical information via the Internet is better suited for younger physicians who are making full use of computers. In contrast, older physicians prefer printed materials because they tend to be less familiar with using computers and may have limited accessibility to the Internet. Therefore, using both the Internet and printed materials to provide medical information is necessary to meet the needs of the larger physician population.

Objective: To examine the effect of pharmacists’ visits to homebound patients on the elimination of unused drugs.
Method: We conducted a survey with pharmacies throughout Japan that provided home-visit service, asking them questions regarding their work with up to five patients (the survey period was from January 15 through the end of February, 2013). Main survey questions were: (1) whether they managed unused drugs since the start of their home-visit, and (2) how they managed the unused drugs. For (2), we conducted case studies by asking the pharmacists to choose the case that impressed them most and describe the unused drugs involved, actions taken, and the results.
Results: Data on 5,447 patients were collected from 1,890 pharmacies throughout Japan (collection rate: 56.9%). Pharmacists managed unused drugs from 2,484 patients (45.6%). 1,746 patients (3,590 cases) were qualified for analysis. In 2,332 cases (65.0%), pharmacist intervention eliminated the incidences of unused drugs. In 782 cases (21.8%), unused drugs were discarded, while the number of drug administration days was adjusted in 2,623 cases (73.1%). In 21 cases (0.6%), drugs were both discarded and had the number of days adjusted. There were others for 164 cases (4.5%). The total price of the eliminated unused drugs was approximately 6,920,000 yen (4,000 yen/person). Illnesses that benefited most from the elimination of unused drugs were chronic respiratory failure (16,306 yen/person), and Parkinson’s disease (4,803 yen/person).
Conclusion: We confirmed the economic effect of eliminating unused drugs by pharmacists’ home visits.

OBJECTIVE: Since there have been few large series studies to date, we investigated the relationship between Trousseau's syndrome associated with cerebral infarction and its clinical associations with ovarian cancer. METHODS: In this study, we investigated the association between cerebral infarction onset and ovarian cancer. Eight-hundred twenty-seven consecutive ovarian cancer patients from 4 affiliated academic institutions were included in the study over a 12 years period. All patients were histopathologically diagnosed as epithelial ovarian cancer and were analyzed retrospectively. RESULTS: The 27 patients (3.2%) presented with cerebral infarction during the study period, 14 patients onset prior to treatment (1.7%), and 13 patients onset after start of initial treatment (1.5%). Univariate analysis and multivariate analysis was performed for onset of Trousseau's syndrome and various clinical and pathological parameters. There was no statistical significance between the occurrence of Trousseau's syndrome with age or International Federation of Gynecology and Obstetrics (FIGO) stage; however, univariate analysis and multivariate analysis demonstrated a statistically significant association between clear cell carcinoma (CCC) and non-CCC histology. CONCLUSION: Thus, our results demonstrate that Trousseau's syndrome with cerebral infarction occurred with greater incidence among CCC cases compared to non-CCC cases.

BACKGROUND/OBJECTIVES: Alzheimer's disease is a neurodegenerative disease that induces symptoms such as a decrease in motor function and cognitive impairment. Increases in the aggregation and deposition of amyloid beta protein (Aβ) in the brain may be closely correlated with the development of Alzheimer's disease. In this study, the effects of an adzuki bean extract on the aggregation of Aβ were examined; moreover, the anti-Alzheimer's activity of the adzuki extract was examined. MATERIALS/METHODS: First, we undertook thioflavin T (ThT) fluorescence analysis and transmission electron microscopy (TEM) to evaluate the effect of an adzuki bean extract on Aβ42 aggregation. To evaluate the effects of the adzuki extract on the symptoms of Alzheimer's disease in vivo, Aβ42-overexpressing Drosophila were used. In these flies, overexpression of Aβ42 induced the formation of Aβ42 aggregates in the brain, decreased motor function, and resulted in cognitive impairment. RESULTS: Based on the results obtained by ThT fluorescence assays and TEM, the adzuki bean extract inhibited the formation of Aβ42 aggregates in a concentration-dependent manner. When Aβ42-overexpressing flies were fed regular medium containing adzuki extract, the Aβ42 level in the brain was significantly lower than that in the group fed regular medium only. Furthermore, suppression of the decrease in motor function, suppression of cognitive impairment, and improvement in lifespan were observed in Aβ42-overexpressing flies fed regular medium with adzuki extract. CONCLUSIONS: The results reveal the delaying effects of an adzuki bean extract on the progression of Alzheimer's disease and provide useful information for identifying novel prevention treatments for Alzheimer's disease.

There has been significant progress in the understanding of the pathology and molecular biology of rare ovarian cancers, which has helped both diagnosis and treatment. This paper provides an update on recent advances in the knowledge and treatment of rare ovarian cancers and identifies gaps that need to be addressed by further clinical research. The topics covered include: low-grade serous, mucinous, and clear cell carcinomas of the ovary. Given the molecular heterogeneity and the histopathological rarity of these ovarian cancers, the importance of designing adequately powered trials or finding statistically innovative ways to approach the treatment of these rare tumors has been emphasized. This paper is based on the Rare Ovarian Tumors Conference for Young Investigators which was presented in Tokyo 2015 prior to the 5th Ovarian Cancer Consensus Conference of the Gynecologic Cancer InterGroup (GCIG).

Introduction: Number of palliative care team increase every year, but the quality of team might differ from each other. We developed “Self-Check Program for Palliative Care Team” to assess and improve the quality of palliative care team. We report the result of the multi-center study to assess the feasibility of this program. Methods: We underwent the “Self-Check Program” as a trial at seven hospitals in Japan in February 2016. We took a questionnaire survey to team leaders and participants to assess the feasibility of this program. Results: Fifty-two medical staffs in six hospitals accomplished this program. Time scheduling and the integration of opinions from each team members were the difficulties came up from questionnaire survey. All team leaders and 87.8% of the participants answered that this program was effective to extract and improve the problem of the team. Also 83.3% of the team leaders were satisfied with the process of planning. Conclusion: Despite some difficulties, majority of the participants considering useful, this program is considered feasible.
