Development of Kampo（traditional Japanese medicine）e-learning program: evaluation of the flipped classroom for medical students.

In May 2019, the World Health Assembly, in an unprecedented move, endorsed the inclusion of traditional medicine in the International Classification of Diseases, 11th Revision. In Japan, traditional medicine (known as Kampo) is regulated by the government and prescribed by over 90% of physicians along with modern medicine under the national health insurance system. Although Kampo education must be included in Japan's core medical curricula, there are significant challenges to implementation. In the educational context, the flipped classroom teaching method has received considerable attention in recent years. This study developed a Kampo e-learning program and verified the effectiveness of a flipped classroom using Kampo e-learning. The Kampo e-learning Committee determined three courses and assigned an administrator for each. The administrators appointed lecturers who developed Kampo e-learning lessons. Physicians, pharmacists, medical students, and pharmacy students were asked to participate in the e-learning program, and their comments and suggestions were collected after program completion. The flipped classroom was evaluated by implementing Kampo e-learning in the Kampo session with fourth-year students at Keio University School of Medicine in Japan. Seven courses were created, including four based on volunteer suggestions. The 'Systematic Kampo Curricula' featured 88 lessons developed by 54 Kampo specialists. Out of 118 fourth-year medical students who participated in the flipped classroom, 113 registered for the Kampo e-learning program, 100 attended the session, and 88 answered the post-session questionnaire. Among the students who answered the questionnaire, 86.4% were satisfied with the flipped classroom, 79.5% replied that the program made them understand Kampo and 80.7% stated that it should be adopted. The flipped classroom using Kampo e-learning program was shown to be attractive in one medical school. Further expanded study is necessary in the near future to reveal the usefulness of the flipped classroom of Kampo learning.

Changes in patient-centered attitude and confidence in communicating with patients: a longitudinal study of resident physicians.

BACKGROUND: Patient-centered care has been one of the most frequently discussed principles in medical practice. However, there is a serious concern that the patient-centered attitudes of physicians diminish over the course of their medical education. This longitudinal study examined changes in resident physicians' patient-centered attitudes and their confidence in communicating with patients, and explored the relationship between the two traits. METHODS: The study participants were resident physicians at a university hospital in Tokyo. Participants' patient-centered attitudes (as measured by the Patient-Practitioner Orientation Scale [PPOS]), and their confidence in communicating with patients (as per the Physician Confidence in the Medical Interview scale: [PCMI]) were assessed through self-reported questionnaires completed at the beginning of residency (n = 204) and again at the end of the first year (n = 95). RESULTS: PPOS scores declined significantly during the year, both in terms of attitude toward sharing information and decision-making with patients, and attitude of caring for patients' expectations and emotions. The shift in caring attitude differed significantly by gender. The increase in PCMI score was greater for those with a smaller decrease in PPOS score. CONCLUSIONS: As seen in previous studies of medical students, resident physicians' patient-centered attitudes declined during their first year of residency, while there may be a gender-based difference within the shift. The increase in physicians' confidence in communicating with patients was greater for those who showed a smaller decline in patient-centered attitude. Additional studies are needed to detail the changes in physicians' attitudes, confidence, and communication skills over the course of their medical training, and to develop systematic assessment and training programs.

The information-giving skills of resident physicians: relationships with confidence and simulated patient satisfaction.

BACKGROUND: Sharing information is crucial for discussion of problems and treatment decision making by patients and physicians. However, the focus of communication skills training in undergraduate medical education has been on building the relationship and gathering information; thus, resident physicians tend to be less confident about sharing information and planning treatment. This study evaluated the medical interviews conducted by resident physicians with a focus on information giving, and investigated its relationships with their confidence in communication and simulated patient (SP) satisfaction. METHODS: Among 137 junior resident physicians at a university hospital in Japan who participated in a survey of communication skills, 25 volunteered to conduct simulated medical interviews. The medical interviews were video-recorded and analyzed using the Roter Interaction Analysis System, together with additional coding to explore specific features of information giving. The SPs evaluated their satisfaction with the medical interview. RESULTS: Resident physicians who were more confident in their communication skills provided more information to the patients, while SP satisfaction was associated only with patient-prompted information giving. SPs were more satisfied when the physicians explained the rationales for their opinions and recommendations. CONCLUSION: Our findings underscore the importance of providing relevant information in response to the patient requests, and explaining the rationales for the opinions and recommendations. Further investigation is needed to clinically confirm our findings and develop an appropriate communication skills training program.

Why do students participate in medical education?

BACKGROUND: Medical student involvement in curriculum development is important; however, little is known about why medical students become engaged in this activity. The aim of this study was to understand what motivates medical students at one university to participate in the process of curriculum development and gain a wider perspective on student engagement in medical education. METHODS: Grounded theory methodology was the foundation of this study. We conducted semi-structured interviews with seven medical students from the University of Tokyo who developed and participated in a group whose aim was to actively contribute towards improving their medical education. The data from the interviews were analysed by thematic synthesis, with triangulation. RESULTS: Three themes emerged as potential explanations for motivating student behaviour: (1) extracurricular interaction with faculty members; (2) engaging with highly motivated peers; and (3) student values for serving the public. CONCLUSIONS: Students working to improve educational processes at their medical schools had the opportunity to communicate more with faculty members, enjoyed opportunities for networking with other highly motivated peers and enhanced aspects of their developing professionalism.

Resident physicians' attitudes and confidence in communicating with patients: a pilot study at a Japanese university hospital.

OBJECTIVE: This study aimed to explore the relationships among physicians' confidence in conducting medical interviews, their attitudes toward the patient-physician relationship, and undergraduate training in communication skills among resident physicians in Japan. METHODS: Participants were 63 first-year resident physicians at a university hospital in Tokyo. The Physician Confidence in the Medical Interview scale (PCMI) was constructed based on the framework of the Calgary-Cambridge Guide. Additionally, participants' attitudes toward the patient-physician relationship (Patient-Practitioner Orientation Scale; PPOS), undergraduate experience of communication skills training, and demographic characteristics were assessed through a self-reported questionnaire. RESULTS: The internal consistency of the PCMI and PPOS scales were adequate. As expected from the undergraduate curriculum for medical interviews in Japan, residents had relatively higher confidence in their communication skills with respect to gathering information and building the relationship, whereas less confident about sharing information and planning treatment. The PCMI was associated with a more patient-centered attitude as measured by the PPOS. CONCLUSION: These scales could be useful tools to measure physicians' confidence and attitudes in communicating with patients and to explore their changes through medical education. PRACTICE IMPLICATIONS: Residency programs should consider including systematic training and assessment in communication skills related to sharing information and planning treatment.

Psychometric item analysis and validation of the Indonesian version of the Readiness for Interprofessional Learning Scale (RIPLS).

Complex health care needs in developing countries are stimulating development and implementation of interprofessional education (IPE). To better understand IPE, it is necessary to develop and evaluate an educational program that focuses on interprofessional learning (IPL) in Indonesia. However, no instrument in the Indonesian language has been developed to measure attitudes toward IPL. The aim of this study is to describe the process of a cross-cultural adaptation of the Readiness for Interprofessional Learning Scale (RIPLS) in an Indonesian version including determining its reliability and validity. The study was conducted among students enrolled in medical, nursing, pharmacy and public health courses at the State Islamic University, Jakarta, Indonesia, in 2012. The completed responses to RIPLS were collected from 755 students. The psychometric properties were analyzed by both exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). EFA on 18-items revealed three factors accounting for 59.9% of the total variance. CFA resulted in a three-factor model over 16 items with satisfactory reliability (alpha coefficients >0.7), construct validity and acceptable indices of goodness of fit. We conclude that this Indonesian version of RIPLS with a three-factor model over 16 items is a valid tool to measure students' attitudes toward IPL.

Cerebral venous thrombosis and "Dense Triangle Sign" on unenhanced head computed tomographic scan.

This case report describes a 21-year-old man with headache who was ultimately diagnosed as having cerebral venous thrombosis(CVT), a rare cause of headache in the emergency department that is sometimes lethal. However, correct diagnosis of CVT is often quite difficult because of a lack of findings in imaging studies. Unenhanced head computed tomography was completely normal in up to 39% of patients diagnosed as having CVT, but a subtle sign known as 'Dense Triangle Sign' was found in this case. This finding disappeared after anticoagulation therapy. Emergency physicians must know about this finding to diagnose this rare condition correctly.

A national survey of international electives for medical students in Japan: 2009-2010.

BACKGROUND AND OBJECTIVES: International electives can provide experiences for medical students to learn about health systems and foster critical self-reflection. So far, little is known about the status of Japanese students' engagement in international electives. We sought to provide information about the internationalization of Japanese medical education by clarifying the current situations of international electives. METHOD: We undertook a cross-sectional national 17-item questionnaire survey of program officers in all medical schools in Japan in February 2010. RESULTS: Sixty-five (81.3%) of 80 Japanese medical schools responded to the questionnaire. 462 Japanese medical students (3% of all students in their clinical years) travelled to North America (45.5%), Asia (25.0%), or Western Europe (24.4%) to study abroad. The number of students who participated in international electives was significantly increased when academic credit was available (median 6 vs. 1, p < 0.001) and institutional affiliations were present (median 7 vs. 2 students, p < 0.001). Most students were evaluated by means of written assignment on return. DISCUSSION AND CONCLUSION: About 3% of Japanese medical students participate in international clinical exchanges. Academic credit and institutional affiliations appear to promote greater utilization of international exchange opportunities.

Enhanced neointimal hyperplasia and carotid artery remodelling in sequestosome 1 deficient mice.

Deficiency in the signal adaptor protein sequestosome 1 (SQSTM1/A170/p62) in mice is associated with mature-onset obesity, accompanied by insulin and leptin resistance. We previously established that redox sensitive transcription factor Nrf2 up-regulates SQSTM1 expression in response to atherogenic stimuli or laminar shear stress in vascular cells, and here examine the role of SQSTM1 in neointimal hyperplasia and vascular remodelling in vivo following carotid artery ligation. Neointimal hyperplasia was markedly enhanced at ligation sites after 3 weeks in SQSTM1(-/-) compared with wild-type (WT) mice. The intimal area and stenotic ratio were, respectively, 2.1- and 1.7-fold higher in SQSTM1(-/-) mice, indicating enhanced proliferation of vascular smooth muscle cells (SMCs). When aortic SMCs were isolated from WT and SQSTM1(-/-) mice and cultured in vitro, we found that SQSTM1(-/-) SMCs proliferated more rapidly in response to foetal calf serum (FCS) and attained 2-3-fold higher cell densities compared to WT SMCs. Moreover, migration of SQSTM1(-/-) SMCs was enhanced compared to WT SMCs. Early and late phases of p38(MAPK) activation in response to FCS stimulation were also more enhanced in SQSTM1(-/-) SMCs, and inhibitors of p38 and ERK1/2 signalling pathways significantly attenuated SMC proliferation. In summary, SQSTM1(-/-) mice exhibit enhanced neointimal hyperplasia and vascular remodelling following arterial ligation in vivo. The enhanced proliferation of SQSTM1(-/-) aortic SMCs in vitro highlights a novel role for SQSTM1 in suppressing smooth muscle proliferation following vascular injury.

Internal exposure to (210)Po and (40)K from ingestion of cooked daily foodstuffs for adults in Japanese cities.

The isotope (210)Po was suspected of being involved in the death of a former Russian intelligence agent in 2006 in the UK. Although human exposure to this natural radionuclide in foods is estimated to be high, few studies are available. UNSCEAR Report 2000 does not contain data on (210)Po concentrations of foodstuffs in Japan. We analyzed samples of the everyday Japanese diet cooked with foodstuffs purchased at supermarkets in 7 major domestic cities in 2007-2008. (210)Po was quantified by alpha spectrometry and natural radionuclides such as (40)K by gamma spectrometry. The daily intake and committed effective dose of (210)Po, (40)K, and other natural radionuclides for Japanese adults were calculated. Daily intake was 0.34-1.84 (mean +/- sigma : 0.66 +/- 0.53) and 68.5-94.2 (81.5 +/- 8.5) Bq/d and the committed effective dose was 0.15-0.81 (0.29 +/- 0.24) and 0.16-0.21 (0.18 +/- 0.02) mSv for (210)Po and (40)K, respectively, comprising a high percentage of the total exposure. The total of the mean committed effective dose for the two nuclides (0.47 mSv) was higher than the annual effective dose from ingestion of foods reported by UNSCEAR 2000 (0.29 mSv). The mean committed effective dose of (40)K in the 7 major Japanese cities was comparable to the global average (0.17 mSv). The dietary exposure of Japanese adults can be characterized by a higher (210)Po contribution than in other countries. Of the total daily dietary (210)Po exposure (13 food categories excluding water) for adults in Yokohama, about 70% was from fish/shellfish and 20% from vegetables/mushrooms/seaweeds, reflecting preferences of Japanese to eat a considerable amount of fish/shellfish containing high (210)Po concentrations.

Long-term results of a multicenter randomized, comparative trial of modified CHOP versus THP-COP versus THP-COPE regimens in elderly patients with non-Hodgkin's lymphoma.

In treating elderly non-Hodgkin's lymphoma (NHL) patients, it is particularly important to use drugs that have a low incidence of adverse events and high efficacy. In this multicenter study, THP (pirarubicin)-COP (cyclophosphamide, vincristine, and prednisolone) was compared to two thirds dosage of full CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisolone) regimen with regard to both adverse events and efficacy. For a third group, etoposide (E) was added to the THP-COP regimen (THP-COPE) in order to achieve high dose-intensity. Subjects were 486 previously untreated patients, aged 65 or older (range, 65-92 years; median, 74 years), with NHL. Subjects were randomly assigned to receive THP-COP, two thirds CHOP, or THP-COPE. Four hundred and forty-three patients were assessed for response and followed for 8 years after the last subject registered. The complete remission rates for the THP-COP, CHOP, and THP-COPE groups were 42.5%, 41.4%, and 48.0%, respectively. There was no difference in overall survival or progression-free survival among these 3 groups. In aggressive lymphoma, there was also no difference in complete response (CR) rate (45.3% in THP-COP, 44.9% in CHOP, 48.0% in THP-COPE), overall survival, and progression-free survival among these groups. The 5- and 8-year survival rates for all patients were 29.4% and 18.7%, respectively. The 5- and 8-year survival rates for patients with aggressive lymphoma were 27.4% and 17.4%, respectively. Although long-term survival for patients with aggressive lymphoma on our regimens was not worse compared to previous reports, the CR rate was lower. Because severe adverse events were not observed, higher dose chemotherapy may be directed to achieve better CR rates. In patients with T-cell-type lymphoma, the CR rate was greater after treatment with THP-COP (51.4%) or THP-COPE (57.7%) compared to treatment with CHOP (19.4%). Pirarubicin may be more useful for T-cell lymphoma than doxorubicin. Because adverse cardiac events were reported only in CHOP, adverse cardiac events might be low in the THP group.

[Hypercalcemia complicated with status nervosus in an elderly patient on hemodialysis during parental nutrition].

An 89-year-old male patient on hemodialysis presented clouding of consciousness caused by hypoglycemia during taking an anti-diabetic agent. His somnolent state continued in spite of glucose dispensation, and parental nutrition was started by a nasogastric tube because he couldn't have peroral ingestion. Though his blood glucose level recovered normal, his consciousness disorder was suspended, and he showed remarkable hypercalcemia. He was dosed with elcatonin, and the parental nutrient was changed to the other one that contained less vitamin D and calcium, and so his serum calcium level diminished slowly but he showed drowsiness about a month long. After resumption of peroral ingestion, his consciousness restored to the former condition rapidly. This case suggests that careful observation is needed in less active dialysis patients with parental nutrition because nutrient-contained vitamin D and calcium, which doesn't harm patients without renal insufficiency, may cause hypercalcemia.
