Long-term clinical clerkship improves medical students' attitudes toward team collaboration.

Objectives: To examine the related factors associated with medical students' attitudes toward team collaboration. Methods: This cross-sectional study targeted medical students, residents, and doctors. A survey was conducted from 2016 to 2017 using the Japanese version of the Jefferson Scale of Attitudes Toward Interprofessional Collaboration (JeffSATIC-J), which evaluated "working relationship" and "accountability." We analyzed 2409 questionnaire responses with JeffSATIC-J items and the gender item. Analysis of variance was used for factors associated with the JeffSATIC-J score and Spearman's rank correlation coefficient for the relationship between educational intervention and the JeffSATIC-J score. Results: First-year students' scores were the highest (F(2, 2045) = 13.42 to 18.87, p < .001), and female students' scores were significantly higher than those of male students (F(1, 2045) = 21.16 to 31.10, p < .001). For residents' scores, the institution was not a significant variable. Female "accountability" scores were significantly higher than those of males (F (1,108) = 4.95, p = .03). Gender was not a significant variable for doctors' scores. Sixth-year students' scores were significantly correlated with the length of clinical clerkship (r(5)=.78 to .96, p<.05), with the exception of females' "working relationship" scores. The medical school with the highest JeffSATIC-J scores had the longest clinical clerkship in the community. Conclusions: These results indicate that long-term clinical clerkship in the community at higher grades is important in improving medical students' attitudes toward team collaboration. A qualitative study is required to confirm our findings.

Education policies to increase rural physicians in Japan: a nationwide cohort study.

BACKGROUND: Japan has established comprehensive education-scholarship programs to supply physicians in rural areas. Their entrants now comprise 16% of all medical students, and graduates must work in rural areas for a designated number of years. These programs are now being adopted outside Japan, but their medium-term outcomes and inter-program differences are unknown. METHODS: A nationwide prospective cohort study of newly licensed physicians 2014-2018 (n = 2454) of the four major types of the programs-Jichi Medical University (Jichi); regional quota with scholarship; non-quota with scholarship (scholarship alone); and quota without scholarship (quota alone)-and all Japanese physicians in the same postgraduate year (n = 40,293) was conducted with follow-up workplace information from the Physician Census 2018, Ministry of Health, Labour and Welfare. In addition, annual cross-sectional survey for prefectural governments and medical schools 2014-2019 was conducted to obtain information on the results of National Physician License Examination and retention status for contractual workforce. RESULTS: Passing rate of the National Physician License Examination was highest in Jichi, followed in descending order by quota with scholarship, the other two programs, and all medical graduates. The retention rate for contractual rural service of Jichi graduates 5 years after graduation (n = 683; 98%) was higher than that of quota with scholarship (2868; 90%; P < 0.001) and scholarship alone (2220; 81% < 0.001). Relative risks of working in municipalities with the least population density quintile in Jichi, quota with scholarship, scholarship alone, and quota alone in postgraduate year 5 were 4.0 (95% CI 3.7-4.4; P < 0.001), 3.1 (2.6-3.7; < 0.001), 2.5 (2.1-3.0; < 0.001), and 2.5 (1.9-3.3; < 0.001) as compared with all Japanese physicians. There was no significant difference between each program and all physicians in the proportion of those who specialized in internal medicine or general practice in postgraduate years 3 to 5 CONCLUSIONS: Japan's education policies to produce rural physicians are effective but the degree of effectiveness varies among the programs. Policymakers and medical educators should plan their future rural workforce policies with reference to the effectiveness and variations of these programs.

Limited effects from professional identity formation-oriented intervention on self-regulated learning in a preclinical setting: a randomized-controlled study in Japan.

BACKGROUND: Developing self-regulated learning in preclinical settings is important for future lifelong learning. Previous studies indicate professional identity formation, i.e., formation of self-identity with internalized values and norms of professionalism, might promote self-regulated learning. We designed a professional identity formation-oriented reflection and learning plan format, then tested effectiveness on raising self-regulated learning in a preclinical year curriculum. METHODS: A randomized controlled crossover trial was conducted using 112 students at Jichi Medical University. In six one-day problem-based learning sessions in a 7-month pre-clinical year curriculum, Groups A (n = 56, female 18, mean age 21.5y ± 0.7) and B (n = 56, female 11, mean age 21.7y ± 1.0) experienced professional identity formation-oriented format: Group A had three sessions with the intervention format in the first half, B in the second half. Between-group identity stages and self-regulated learning levels were compared using professional identity essays and the Motivated Strategies for Learning Questionnaire. RESULTS: Two-level regression analyses showed no improvement in questionnaire categories but moderate improvement of professional identity stages over time (R2 = 0.069), regardless of timing of intervention. CONCLUSIONS: Professional identity moderately forms during the pre-clinical year curriculum. However, neither identity nor self-regulated learning is raised significantly by limited intervention.

Does changing from a teacher-centered to a learner-centered context promote self-regulated learning: a qualitative study in a Japanese undergraduate setting.

BACKGROUND: Previous studies indicate that a teacher-centered context could hinder undergraduates from self-regulated learning (SRL), whereas a learner-centered context could promote SRL. However, SRL development between a teacher-centered and a learner-centered context has not directly compared in undergraduate settings. Also, it is still unclear how a contextual change toward learner-centered learning could influence SRL in students, who are strongly accustomed to teacher-centered learning. METHODS: We conducted three focus groups that examined 13 Japanese medical students who left a traditional curriculum composed of didactic lectures and frequent summative tests and entered a seven-month elective course (Free Course Student Doctor or FCSD). The FCSD emphasizes student-designed individualized learning with support and formative feedback from mentors chosen by students' preference. We also conducted two focus groups that examined 7 students who remained in the teacher-centered curriculum during the same period. Students were asked to discuss their 1) motivation, 2) learning strategies, and 3) self-reflection on self-study before and during the period. Data were analyzed using thematic analysis and code comparison between the two cohorts. RESULTS: The non-FCSD participants described their motivational status as being one among a crowd set by the teacher's yardstick. Their reflection focused on minimizing the gap between themselves and the teacher-set yardstick with strategies considered monotonous and homogeneous (e.g. memorization). FCSD participants described losing the teacher-set yardstick and constructing their future self-image as an alternative yardstick. They compared gaps between their present status and future self-image by self-reflection. To fill these gaps, they actively employed learning strategies used by doctors or mentors, leading to diversification of their learning strategies. CONCLUSIONS: A contextual change toward learner-centered learning could promote SRL even in students strongly accustomed to teacher-centered learning. In the learner-centered context, students began to construct their self-image, conduct self-reflection, and seek diverse learning strategies by referring to future 'self' models.

Liver dysfunction in anti-melanoma differentiation-associated gene 5 antibody-positive patients with dermatomyositis.

The objective was to investigate the clinical and histological features of liver dysfunction in patients with polymyositis (PM) or dermatomyositis (DM).A total of 115 patients (38 with PM and 77 with DM), who were admitted to our hospital between 2001 and 2012, were retrospectively reviewed. Liver dysfunction was defined as an alanine transaminase (ALT) level ≥ 60 U/l and a disproportionate ALT elevation relative to the creatine kinase level. The histological findings from liver biopsies were also assessed.The frequencies of liver dysfunction were 3% and 17% in the patients with PM and DM, respectively. Liver dysfunction was not observed in the patients who had malignancies. Among the patients with DM with no malignancies (n = 50), 20% had liver dysfunction, and all of the patients with liver dysfunction were positive for the anti-melanoma differentiation-associated gene 5 (MDA5) antibody. Compared with those in the patients who did not have liver dysfunction, the ALT, alkaline phosphatase, γ-glutamyl transferase, and KL-6 levels were significantly elevated in the patients who had liver dysfunction. Six patients, comprising four with DM and two with PM, underwent liver biopsies, and the common histological findings associated with DM were steatosis, hepatocyte ballooning, increases in the pigmented macrophage numbers, and glycogenated nuclei. Hemophagocytosis was detected in two of three patients with DM who underwent liver biopsies and bone marrow aspirations. In conclusion, Liver dysfunction might be an extramuscular manifestation in patients with DM who are anti-MDA5 antibody-positive. Steatosis and hepatocyte ballooning could be common histological features.

Contextual attributes promote or hinder self-regulated learning: A qualitative study contrasting rural physicians with undergraduate learners in Japan.

BACKGROUND AND OBJECTIVES: Previous studies support the notion that East Asian medical students do not possess sufficient self-regulation for postgraduate clinical training. However, some East Asian physicians who are employed in geographically isolated and educationally underserved rural settings can self-regulate their study during the early phase of their postgraduate career. To explore the contextual attributes that contribute to self-regulated learning (SRL), we examined the differences in self-regulation between learning as an undergraduate and in a rural context in East Asia. METHODS: We conducted interviews and diary data collection among rural physicians (n = 10) and undergraduates (n = 11) in Japan who undertook self-study of unfamiliar diseases. We analyzed three domains of Zimmerman's definition of SRL: learning behaviors, motivation, and metacognition using constructivist grounded theory. RESULTS: Rural physicians recognized their identity as unique, and as professionals with a central role of handling diseases in the local community by conducting self-study. They simultaneously found themselves being at risk of providing inappropriate aid if their self-study was insufficient. They developed strategic learning strategies to cope with this high-stakes task. Undergraduates had a fear of being left behind and preferred to remain as one of the crowd with students in the same school year. Accordingly, they copied the methods of other students for self-study and used monotonous and homogeneous strategies. CONCLUSIONS: Different learning contexts do not keep East Asian learners from being self-regulated. Awareness of their unique identity leads them to view learning tasks as high-stakes, and to initiate learning strategies in a self-regulated manner. Teacher-centered education systems cause students to identify themselves as one of the crowd, and tasks as low-stakes, and to accordingly employ non-self-regulated strategies.

A first report of East Asian students' perception of progress testing: a focus group study.

BACKGROUND: Progress testing (PT) is used in Western countries to evaluate students' level of functional knowledge, and to enhance meaning-oriented and self-directed learning. However, the use of PT has not been investigated in East Asia, where reproduction-oriented and teacher-centered learning styles prevail. Here, we explored the applicability of PT by focusing on student perceptions. METHODS: Twenty-four students from Years 2, 3, and 5 at Jichi Medical University in Japan attended a pilot PT session preceded by a brief introduction of its concept and procedures. Variations in obtained test scores were analyzed by year, and student perceptions of PT were explored using focus groups. RESULTS: Formula scores (mean ± standard deviation) in Years 2, 3, and 5 were 12.63 ± 3.53, 35.88 ± 14.53, and 71.00 ± 18.31, respectively. Qualitative descriptive analysis of focus group data showed that students disfavored testing of medical knowledge without tangible goals, but instead favored repetitive assessment of knowledge that had been learned and was tested on a unit basis in the past in order to achieve deep learning. Further, students of all school years considered that post-test explanatory lectures by teachers were necessary. CONCLUSIONS: East Asian students' perceptions indicated that, in addition to their intensive memorization within narrow test domains compartmentalized by end-of-unit tests, the concept of PT was suitable for repetitive memorization, as it helped them to integrate their knowledge and to increase their understanding. Post-test explanatory lectures might lessen their dislike of the intangible goals of PT, but at the expense of delaying the development of self-directed learning. Key issues for the optimization of PT in East Asia may include administration of PT after completed end-of-unit tests and a gradual change in feedback methodology over school years from test-oriented post-test lectures to the provision of literature references only, as a means of enhancing test self-review and self-directed learning.

Sustained elevation of interleukin-33 in sera and synovial fluids from patients with rheumatoid arthritis non-responsive to anti-tumor necrosis factor: possible association with persistent IL-1ß signaling and a poor clinical response.

Although TNF inhibitors have dramatically improved the outcome of patients with rheumatoid arthritis, 30-40% of patients do not respond well to them and treatment needs to be changed. In an effort to discriminate good and poor responders, we focused on the change in serum and synovial fluid levels of interleukin (IL-) 33 before and after treatment with TNF inhibitors. They were also measured in synovial fluids from 17 TNF inhibitor-naïve patients, and fibroblast-like synoviocytes (FLS) in-culture from 6 patients and correlated with various pro-inflammatory cytokines. Serum levels of IL-33 at 6 months after treatment decreased significantly in responders, while they did not change in non-responders. Synovial fluid levels of IL-33 in 6 patients under treatment with TNF inhibitors stayed high in 3 who were refractory and slightly elevated in 2 moderate responders, while they were undetectable in one patient under remission. Among inflammatory cytokines measured in 17 synovial fluids from TNF inhibitor-naïve patients, levels of IL-33 showed a significant positive correlation only to those of IL-1ß. IL-1ß increased IL-33 expression markedly in FLS in vitro, compared to TNF-α. IL-1ß might be inducing RA inflammation through producing pro-inflammatory IL-33 in TNF inhibitor-hypo-responders. Sustained elevation of serum and/or synovial levels of IL-33 may account for a poor response to TNF inhibitors, although how TNF inhibitors affect the level of IL-33 remains to be elucidated.

Successful treatment of a patient with rheumatoid arthritis and IgA-κ multiple myeloma with tocilizumab.

A 63-year-old woman receiving tumor necrosis factor (TNF) inhibitors for rheumatoid arthritis (RA) was found to have smoldering IgA-kappa type multiple myeloma (MM). Retrospective examination of stored serum samples revealed a steady increase of serum IgA levels after the start of TNF inhibitor therapy. The patient's articular symptoms showed marked exacerbation when TNF inhibitors were discontinued because of fear of worsening the MM. Tocilizumab improved RA symptoms dramatically and stabilized serum IgA levels for 13 months after a transient steep rise. This case suggests that tocilizumab can be used safely in patients with inflammatory disorders with coexisting MM.

Increased levels of interleukin 33 in sera and synovial fluid from patients with active rheumatoid arthritis.

OBJECTIVE: To determine levels of interleukin 33 (IL-33) in serum and synovial fluid (SF) and their clinical associations in patients with rheumatoid arthritis (RA). To evaluate the ability of activated peripheral blood mononuclear cells (PBMC) and fibroblast-like synoviocytes (FLS) from RA patients to release IL-33. METHODS: Sera were obtained from 59 patients with RA, 10 patients with infectious diseases, and 42 healthy volunteers. SF samples were obtained from 15 patients with RA and 13 with osteoarthritis. IL-33 levels were measured using a sandwich ELISA after removal of rheumatoid factor with protein A-Sepharose beads. FLS were stimulated with IL-1beta and tumor necrosis factor, and treated with or without chemical damage. PBMC were stimulated with anti-CD3/CD28 antibodies. The levels of IL-33 were measured in the culture supernatants and cell lysates by ELISA or immunoblotting. RESULTS: Serum IL-33 levels were significantly higher in RA patients, especially in the high disease activity group compared to the moderate or low activity group. IL-33 levels in SF were elevated in all 15 RA patients measured. IL-33 levels were higher in SF samples than in sera in 7 RA patients measured simultaneously. The 30-kDa IL-33 precursor was detected in the culture supernatants of damaged FLS but was not detected in those of activated PBMC and non-damaged FLS. CONCLUSION: IL-33 levels were elevated in sera and SF samples from patients with RA, and correlated with disease activity. IL-33 was produced mainly in inflamed joints; IL-33/ST2L signaling might play an important role in joint inflammation of human RA.

Mature interleukin-33 is produced by calpain-mediated cleavage in vivo.

Interleukin (IL)-33 is a novel member of the IL-1 family. IL-33 is primarily synthesized as a 30-kDa precursor (pro-IL-33). Pro-IL-33 is cleaved by caspase-1 into an 18-kDa mature form (mature IL-33) in vitro. Recombinant mature IL-33 has been known to induce T-helper type-2 (Th2)-associated cytokines and inflammatory cytokines via its receptor, ST2L. However, processing of pro-IL-33 in vivo has not been clarified yet. Here, we report that calpain mediates pro-IL-33 processing in vivo. Pro-IL-33 was expressed by stimulating human epithelial cells with phorbol 12-myristate 13-acetate. Calcium ionophore induced pro-IL-33 cleavage and mature IL-33 production. This cleavage was inhibited by treatment with a calcium chelator and calpain inhibitors. Moreover, short interfering RNA-mediated knockdown of calpains suppressed pro-IL-33 cleavage. These results indicate that calpains play a critical role in pro-IL-33 processing in vivo.

Incidence of antisperm antibodies in males with systemic autoimmune diseases.

PROBLEM: To investigate if systemic autoimmune diseases could be one of the risk factors for developing antisperm antibodies (ASA) in males. METHOD OF STUDY: Antisperm antibodies in the sera of 70 males with systemic autoimmune diseases and 80 healthy controls were examined, by using the indirect-immunobead test (I-IBT). The sperm immobilization test (SIT) was also performed to detect sperm immobilizing antibodies to the patients who were positive in I-IBT. RESULTS: Among 70 males with systemic autoimmune diseases, five were I-IBT positives, with incidence of 7.1%. However, no positives existed in 80 healthy males. Compared with the healthy controls, the incidence of ASA in males with systemic autoimmune diseases was significantly higher (P = 0.020). None of these five ASA-positive patients had sperm immobilizing antibodies. CONCLUSION: The incidence of ASA in males with systemic autoimmune diseases was significantly higher than in the healthy controls. Systemic autoimmune diseases may be one of the risk factors for developing ASA in men.

Glucocorticoid and cyclosporine refractory adult onset Still's disease successfully treated with tocilizumab.

We report a 29-year-old Japanese woman with disseminated intravascular coagulation (DIC) and adult onset Still's disease (AOSD). Her disease was refractory to high-dose glucocorticoids, two courses of steroid pulse therapy, and addition of cyclosporine (3.5 mg/kg/day). The serum interleukin-6 level was markedly elevated. Therefore, we administered an anti-interleukin-6 receptor antibody (tocilizumab, 8 mg/kg fortnightly), which dramatically improved her symptoms and the levels of acute-phase proteins. In addition, rapid tapering of the glucocorticoid dose was possible. Four months later, she was maintained on tocilizumab infusion once a month with low-dose steroid therapy. Cyclosporine is one of the first-line immunosuppressants for AOSD, especially when associated with DIC, hepatic failure, or hemophagocytic syndrome. In patients with cyclosporine-resistant AOSD, tocilizumab may be another useful option.

Prognostic indicators related to death in patients with Pneumocystis pneumonia associated with collagen vascular diseases.

The objective of this study is to investigate the clinical markers of life-threatening Pneumocystis pneumonia (PCP) in patients with collagen vascular diseases (CVD). The patients who contracted Pneumocystis jeroveccii were retrospectively selected from our medical charts and conditions related to the patients' death were reviewed. The findings indicated that lower levels of serum albumin and cholinesterase, increased alveolar-arterial oxygen gradient, intratracheal intubation, and necessity to treat in the intensive care unit were significantly related to deaths associated with PCP in CVD. A special attention should be paid to decreased serum albumin and cholinesterase as ominous predictors in PCP occurred in patients with CVD.

Protein-losing gastroenteropathy associated with primary Sjögren's syndrome: a characteristic oriental variant.

Protein-losing gastroenteropathy (PLGE) is a rare manifestation of primary Sjögren's syndrome (SS). We report a case of a 41-year-old Japanese man, who is the first male patient, with PLGE associated with primary SS. Although serum anti-SSA and SSB antibodies were detected, he had no subjective sicca symptoms. He had multiple annular erythema: a characteristic skin manifestation of Asian SS patients. A diagnosis of PLGE was made from results of (99m)Tc-labelled albumin scintigraphy and a faecal alpha-1-antitrypsin clearance test. Intravenous administration of high-dose glucocorticoid was not effective, but pulse methylprednisolone therapy alleviated disease manifestations. As all cases of PLGE associated with primary SS have been reported from East Asia, this complication could be essentially limited to Asian patients.

Steroid-refractory severe hepatic failure in adult onset Still's disease responding to cyclosporine.

We report two Japanese women with severe hepatic dysfunction and adult onset Still's disease. A 51-year-old woman had been diagnosed with adult onset Still's disease 3 years earlier. She relapsed while on maintenance therapy with prednisolone and methotrexate. After induction of remission with methylprednisolone pulse therapy, indomethacin, and methotrexate, severe hepatic failure occurred. This patient lacked the typical symptoms of adult onset Still's disease. The second patient was a 32-year-old woman with typical adult onset Still's disease. Remission was induced by high-dose prednisolone and methylprednisolone pulse therapy plus cyclosporine. After she stopped cyclosporine, severe liver dysfunction occurred. In both patients, liver dysfunction occurred during high-dose steroid therapy, and oral cyclosporine (3 mg/kg per day) dramatically improved their liver function. When steroid-resistant severe hepatic failure occurs in patients with adult onset Still's disease, cyclosporine may be the immunosuppressant of choice.
