    Introduction: Previous studies indicate that professional identity formation (PIF), the formation of a self-identity with the internalised values and norms of professionalism, may influence self-regulated learning (SRL). However, it remains unclear whether a PIF-oriented intervention can improve SRL in clinical education. The aim of this study was to explore whether a PIF-oriented mentoring platform improves SRL in a clinical clerkship. Methods: A mixed-methods study was conducted. Forty-one students in a community-based clinical clerkship (CBCC) used a PIF-oriented mentoring platform. They articulated the values and norms of professionalism in a professional identity essay, elaborated on future professional self-image, and reflected on their current compared to future selves. They made a study plan while referring to PIF-based self-reflection and completed it. The control group of 41 students completed CBCC without the PIF-oriented mentoring platform. Changes in SRL between the two groups were quantitatively compared using the Motivated Strategies for Learning Questionnaire. We explore how PIF elements in the platform affected SRL by qualitative analysis of questionnaire and interview data. Results: A moderate improvement in intrinsic goal orientation (p = 0.005, ε2 = 0.096) and a mild improvement in critical thinking (p = 0.041, ε2 = 0.051) were observed in the PIF-oriented platform group. Qualitative analysis revealed that the PIF-oriented platform fostered professional responsibility as a key to expanding learning goals. Gaining authentic knowledge professionally fostered critical thinking, and students began to elaborate knowledge in line with professional task processes. Conclusion: A PIF-oriented mentoring platform helped students improve SRL during a clinical clerkship.

    <title>Abstract</title><sec> <title>Background</title> 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. </sec><sec> <title>Methods</title> 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 (<italic>n</italic> = 56, female 18, mean age 21.5y ± 0.7) and B (<italic>n</italic> = 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. </sec><sec> <title>Results</title> Two-level regression analyses showed no improvement in questionnaire categories but moderate improvement of professional identity stages over time (<italic>R</italic>2 = 0.069), regardless of timing of intervention. </sec><sec> <title>Conclusions</title> Professional identity moderately forms during the pre-clinical year curriculum. However, neither identity nor self-regulated learning is raised significantly by limited intervention. </sec>

    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.
