Objectives : We analyzed the mortality and morbidity of congenital heart surgery in Japan by using Japan Cardiovascular Surgery Database (JCVSD). Methods : The congenital heart surgery performed between January 2017 to December 2018 were obtained from JCVSD. From the data obtained, the most frequent twenty procedures were selected, and the mortalities and major morbidities were analyzed. In addition, all the procedures were classified into STAT Mortality Categories and mortalities in each category were also analyzed. Results : The mortality of ASD repair and VSD repair were 0% and 0.2% respectively. The mortality of TOF repair, complete AVSD repair, Rastelli operation, CoA complex repair, bidirectional Glenn, TCPC were 2-3%. The mortality of systemic to pulmonary shunt was 4.9%, and the mortality of TAPVC repair and Norwood procedure were 11.1% and 15.7% respectively and not different from the results of 2015-2016. The mortalities according to the STAT categories 1-5 were 0.3%, 2.7%, 2.9%, 5.9% and 15.5% respectively and comparable to those of STS database (2013-2016). Conclusion : The analysis of the JCVSD-congenital data revealed the mortality rate of major surgical procedures for congenital heart disease performed in Japan in 2017-2018, the frequency of complications, and the mortality rate by STAT Mortality Categories. We believe that these statistics will play an important role as a basis for trends in Japan and for comparison of results with other countries.

Methods : We collated the nationwide data on congenital heart operations performed between January 2015 and December 2016 from the Japan Cardiovascular Surgery Database (JCVSD). The mortality and morbidity data for the 20 most-frequently performed procedures were analyzed. We also classified the surgical centers into three groups, according to the number of cardiopulmonary cases over a year and estimated the institution-wise distribution of major operations. Results : The mortality rate of the ASD and VSD repair procedures was <1%, while the mortality rate of procedures including TOF repair, complete AVSD repair, Rastelli operation, CoA complex repair, bidirectional Glenn and TCPC was found to be between 2-3%. The mortality rate of surgeries such as the Norwood procedure and TAPVC repair was comparably higher (>10%). These complicated procedures were mainly performed at the surgical institutes handling a large volume of cases. Conclusion : Using the JCVSD, the nationwide data of congenital heart surgery, including postoperative complications, were analyzed.

Objective: Caffeine may cause dependence and sleep disturbance, and interact with psychotropic drugs. Therefore, the caffeine intake of patients with mental disorders should be monitored. However, in Japan, there is no report on the effects of caffeine in mental disease patients or on their caffeine intake. Therefore, we conducted a questionnaire survey to clarify the perception of caffeine for psychiatric outpatients.Methods: We conducted an anonymous survey on caffeine recognition for outpatients at 8 medical institutions that advocate psychiatry.Results: We collected questionnaires from 180 people. The knowledge of foods containing caffeine tended to be high in those who had a positive attitude toward caffeine. More than 90% of those surveyed knew that coffee contains caffeine, but cocoa and jasmine tea were recognized by less than 25%. Of those surveyed, 39.4% consumed caffeine‐containing beverages at night. In addition, the rate of consumption of caffeine‐containing beverages tended to be higher at night because they had a positive attitude toward caffeine.Conclusion: The knowledge and intake situation of caffeine by patients with mental disorders differed depending on their interests and way of thinking about caffeine. As caffeine intake may influence psychiatric treatment, correct knowledge regarding caffeine is important.

OBJECTIVE: Palonosetron is effective for the management of acute and delayed chemotherapy-induced nausea and vomiting (CINV). While emetogenic carboplatin-based chemotherapy is widely used to treat gynecologic cancers, few studies have evaluated the antiemetic effectiveness of palonosetron in this setting. METHODS: A multicenter, single-arm, open-label phase II trial was conducted to evaluate the safety and effectiveness of palonosetron in controlling CINV in patients with gynecologic cancer. Chemotherapy-naïve patients received intravenous palonosetron (0.75 mg/body) and dexamethasone before the infusion of carboplatin-based chemotherapy on day 1. Dexamethasone was administered (orally or intravenously) on days 2–3. The incidence and severity of CINV were evaluated using the patient-completed Multinational Association of Supportive Care in Cancer Antiemesis Tool and treatment diaries. The primary endpoint was the proportion of patients experiencing complete control (CC) of vomiting, with “no rescue antiemetic medication” and “no clinically significant nausea” or “only mild nausea” in the delayed phase (24–120 hours post-chemotherapy). Secondary endpoints were the proportion of patients with a complete response (CR: “no vomiting” and “no rescue antiemetic medication”) in the acute (0–24 hours), delayed (24–120 hours), and overall (0–120 hours) phases, and CC in the acute and overall phases. RESULTS: Efficacy was assessable in 77 of 80 patients recruited. In the acute and delayed phases, the CR rates the primary endpoint, were 71.4% and 59.7% and the CC rates, the secondary endpoint, were 97.4% and 96.1%, respectively. CONCLUSION: While palonosetron effectively controls acute CINV, additional antiemetic management is warranted in the delayed phase after carboplatin-based chemotherapy in gynecologic cancer patients (Trial registry at UMIN Clinical Trials Registry, UMIN000012806).

Objectives : We analyzed the mortality and morbidity of congenital heart surgery in Japan by using the Japan Cardiovascular Surgery Database (JCVSD). Methods : Data regarding congenital heart surgery performed between January 2013 and December 2014 were obtained from JCVSD. The 20 most frequent procedures were selected and the mortality rates and major morbidities were analyzed. Results : The mortality rates of atrial septal defect (ASD) repair and ventricular septal defect (VSD) repair were less than 1%, and the mortality rates of tetralogy of Fallot (TOF) repair, complete atrioventricular septal defect (AVSD) repair, bidirectional Glenn, and total cavopulmonary connection (TCPC) were less than 2%. The mortality rates of the Norwood procedure and total anomalous pulmonary venous connection (TAPVC) repair were more than 10%. The rates of unplanned reoperation, pacemaker implantation, chylothorax, deep sternal infection, phrenic nerve injury, and neurological deficit were shown for each procedure. Conclusion : Using JCVSD, the national data for congenital heart surgery, including postoperative complications, were analyzed. Further improvements of the database and feedback for clinical practice are required.

The JCVSD (Japan Cardiovascular Surgery Database) was organized in 2000 to improve the quality of cardiovascular surgery in Japan. Web-based data harvesting on adult cardiac surgery was started (Japan Adult Cardiovascular Surgery Database, JACVSD) in 2001, and on congenital heart surgery (Japan Congenital Cardiovascular Surgery Database, JCCVSD) in 2008. Both databases grew to become national databases by the end of 2013. This was influenced by the success of the Society for Thoracic Surgeons' National Database, which contains comparable input items. In 2011, the Japanese Board of Cardiovascular Surgery announced that the JACVSD and JCCVSD data are to be used for board certification, which improved the quality of the first paperless and web-based board certification review undertaken in 2013. These changes led to a further step. In 2011, the National Clinical Database (NCD) was organized to investigate the feasibility of clinical databases in other medical fields, especially surgery. In the NCD, the board certification system of the Japan Surgical Society, the basic association of surgery was set as the first level in the hierarchy of specialties, and nine associations and six board certification systems were set at the second level as subspecialties. The NCD grew rapidly, and now covers 95% of total surgical procedures. The participating associations will release or have released risk models, and studies that use 'big data' from these databases have been published. The national databases have contributed to evidence-based medicine, to the accountability of medical professionals, and to quality assessment and quality improvement of surgery in Japan.

1) We found that students of the Graduate Entry Program (GEP) had the will to realize the aim of the recruitment but did not think highly of the GEP and were not highly motivated to contribute to medicine, the school, or the region. These findings reflect their low self-evaluation and their lack of real activities.
2) The GEP students had various proposals about the recruitment and examination methods of the GEP. Most proposals request clarification of how the program fits into the university's future goals.
3) Many GEP students foresaw that 5 to 10 years would be needed to distinguish themselves to from non-GEP students. At that time, more extensive research on GEP should be conducted.

This review is partly composed of the presentation "Cytokine alteration and speculated immunological pathophysiology in silicosis and asbestos-related diseases" delivered during the symposium "Biological effects of fibrous and particulate substances and related areas" organized by the Study Group of Fibrous and Particulate Studies of the Japanese Society of Hygiene and held at the 78th Annual Meeting in Kumamoto, Japan. In this review, we briefly introduce the results of recent immunological analysis using the plasma of silica and asbestos-exposed patients diagnosed with silicosis, pleural plaque, or malignant mesothelioma. Thereafter, experimental background and speculation concerning the immunological pathophysiology of silica and asbestos-exposed patients are discussed.

It is common knowledge that exposure to asbestos causes asbestos-related diseases, such as asbestosis, lung cancer and malignant mesothelioma, not only in people who have had long-term contact with asbestos in their work environment but also in residents living near factories that handle asbestos. Since the summer of 2005, these revelations turned into a large medical problem and caused and social unrest. We have focused on the immunological effects of both asbestos and silica on the human immune system. In this brief review, we introduce immunological alterations found in patients with malignant mesothelioma and describe the experimental background in which these were found. Analyzing the immunological effects of asbestos may improve our understanding of the biological effects of asbestos.

Silica and silicates may disturb immune functions such as autoimmunity and tumor immunity, because people who are exposed to the materials sometimes develop autoimmune and malignant diseases, respectively. Although silica-induced disorders of autoimmunity have been explained as adjuvant-type effects of silica, more precise analyses are needed and should reflect the recent progress in immunomolecular findings. A brief summary of our investigations related to the immunological effects of silica/asbestos is presented. Recent advances in immunomolecular studies led to detailed analyses of the immunological effects of asbestos and silica. Both affect immuno-competent cells and these effects may be associated with the pathophysiological development of complications in silicosis and asbestos-exposed patients such as the occurrence of autoimmune disorders and malignant tumors, respectively. In addition, immunological analyses may lead to the development of new clinical tools for the modification of the pathophysiological aspects of diseases such as the regulation of autoimmunity or tumor immunity using cell-mediated therapies, various cytokines, and molecule-targeting therapies. In particular, as the incidence of asbestos-related malignancies is increasing and such malignancies have been a medical and social problem since the summer in 2005 in Japan, efforts should be focused on developing a cure for these diseases to eliminate the nation wide anxiety about these malignancies.
