kn-abstract=Background The World Health Organization first declared the coronavirus disease 2019 (COVID-19) pandemic in March 2020 and announced the end of the emergency in May 2023. Additionally, the COVID-19 pandemic significantly impacted individuals globally, including medical students. Although the COVID-19 pandemic increased online education, it restricted clinical training, extracurricular activities, and interprovincial travel. Therefore, this study aimed to examine whether the COVID-19 pandemic influenced the choice of training hospitals and career paths among 3rd- to 6th-year medical students in Japan.
Methods We developed a questionnaire comprising 21 multiple-choice and 1 open-ended questions, which was administered anonymously via online platforms. The survey targeted Japanese medical students to obtain insights into their preferences for training hospitals and career paths during the COVID-19 pandemic. Participants included 4th- to 6th-year medical students from 51 medical schools in Japan. The survey was conducted through student networks from 8 February 2022 to 20 March 2022.
Results Overall, 507 medical students participated in the survey, with representation from various academic years as follows: 102 (20.1%), 134 (26.4%), 121 (23.9%), and 150 (29.6%) students from the 3rd, 4th, 5th, and 6th year, respectively. Of these, 338 (66.6%) students reported that the COVID-19 pandemic had influenced their choice of training hospitals. The degree of the influence varied based on the university region and the student year. However, most of the students (473, 93.3%) did not change their course for clinical, basic research, or administrative pathways due to the COVID-19 pandemic. Among the clinically oriented students, 391 (77.2%) did not change their preferred speciality.
Conclusions The COVID-19 pandemic influenced medical students' choice of training hospitals. Although many students believed that the pandemic would not change their career choices, our results indicate a potential subconscious trend to avoid internal medicine, which is the speciality most directly involved in treating patients with COVID-19.

kn-title=The effectiveness of simulation-based education combined with peer-assisted learning on clinical performance of first-year medical residents: a case-control study
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background Simulation-based education and peer-assisted learning (PAL) are both known as useful educational methods. Previous research has reported that combining these two methods are effective for training medical residents in short-term evaluation. This study was aimed to evaluate the middle- to long-term effects of simulation-based education combined with PAL on the performance of medical residents during emergency department duties.
Methods This study was designed as a case-control study and conducted over three years at Okayama University Hospital in Japan. Postgraduate-year-one medical residents were assigned to three groups: a simulation group that received simulation-based education, a lecture group that received traditional lecture-based education, and a control group that received no such prior trainings. Prior training in emergency department duties using PAL was performed as an educational intervention for the simulation and lecture groups during the clinical orientation period. The residents' medical knowledge was assessed by written examinations before and after the orientation. The performance of residents during their emergency department duties was assessed by self-evaluation questionnaires and objective-assessment checklists, following up with the residents for three months after the orientation period and collecting data on their 1st, 2nd, and 3rd emergency department duties. All the datasets collected were statistically analyzed and compared by their mean values among the three groups.
Results A total of 75 residents were included in the comparative study: 27 in the simulation group, 24 in the lecture group, and 24 in the control group. The simulation and lecture groups obtained significantly higher written examination scores than the control group. From the self-evaluation questionnaires, the simulation group reported significantly higher satisfaction in their prior training than the lecture group. No significant differences were found in the emergency department performance of the residents among the three groups. However, when evaluating the improvement rate of performance over time, all three groups showed improvement in the subjective evaluation, and only the simulation and lecture groups showed improvement in the objective evaluation.ConclusionSimulation-based education combined with PAL is effective in improving the knowledge and satisfaction of medical residents, suggesting the possibility of improving work performance during their emergency department duties.

kn-title=Effects of Yoga and Mindfulness Programs on Self-Compassion in Medical Professionals during the COVID-19 Pandemic: An Intervention Study
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Stress among healthcare workers (HCWs) increased during the coronavirus disease 2019 pandemic. We aimed to determine whether a yoga and mindfulness program could alleviate burnout and other psychological and physical distress in HCWs, and how this might affect their empathy for patients. A weekly one-hour yoga and mindfulness program was conducted for three months in 2021. Participants were 18 consenting HCWs and, the final analysis included 13 participants. They responded to online questionnaires before and after the program. We measured salivary cortisol levels before and after the program on the first and last days. Self-measured pulse rates (PRs) were taken before and after each session, which decreased significantly in both cases (before, after the first program: 72, 65 bpm, p < 0.05; before, after the last program: 75, 66, p < 0.05), but salivary cortisol levels did not change. No significant changes were observed in Patient Health Questionnaire-9, Maslach Burnout Inventory, Sense of Coherence, Connor-Davidson Resilience Scale, Self-compassion Scale, or Jefferson Scale of Empathy. However, common humanity, a subscale of self-compassion, increased significantly (before the first program: 5.6, after the last program: 6.5, p < 0.05), and over-identification decreased significantly (7.9, 6.7, p < 0.01). Yoga and mindfulness programs may help improve the sense of common humanity and reduce over-identification in HCWs.

kn-title=Burnout of Healthcare Workers Amid the COVID-19 Pandemic: A Follow-Up Study
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The coronavirus disease 2019 (COVID-19) pandemic has posed a significant challenge to the modern healthcare system and led to increased burnout among healthcare workers (HCWs). We previously reported that HCWs who engaged in COVID-19 patient care had a significantly higher prevalence of burnout (50.0%) than those who did not in November 2020 (period 1). We performed follow-up surveys in HCWs in a Japanese national university hospital, including basic demographics, whether a participant engaged in care of COVID-19 patients in the past 2 weeks, and the Maslach Burnout Inventory in February 2021 (period 2) and May 2021 (period 3). Periods 1 and 3 were amid the surges of COVID-19 cases, and period 2 was a post-surge period with a comparatively small number of COVID-19 patients requiring hospitalization. Response rates to the surveys were 33/130 (25.4%) in period 1, 36/130 (27.7%) in period 2, and 56/162 (34.6%) in period 3, respectively. While no consistent tendency in the prevalence of burnout based on variables was observed throughout the periods, the prevalence of burnout tends to be higher in periods 1 and 3 in those who engaged in COVID-19 patient care in the last 2 weeks (50.0%, 30.8%, 43.1% in period 1, 2, and 3, respectively). Given the prolonged pandemic causing stigmatization and hatred against HCWs leading to increased prevalence of burnout, high-level interventions and supports are warranted.

en-abstract=
kn-abstract=The coronavirus disease 2019 (COVID-19) global pandemic has drastically changed how we live and work. Amid the prolonged pandemic, burnout of the frontline healthcare professionals has become a significant concern. We conducted a cross-sectional survey study to provide data about the relationship between the COVID-19 pandemic and the prevalence of burnout in healthcare professionals in Japan. Healthcare workers in a single Japanese national university hospital participated in the survey, including basic demographics, whether a participant engaged in care of COVID-19 patients in the past 2 weeks and the Maslach Burnout Inventory. Of those, 25.4% fully answered the survey; 33.3% were doctors and 63.6% were nurses, and 36.3% engaged in care of COVID-19 patients in the past 2 weeks. Compared to those belonging to General Medicine, those in Emergency Intensive Care Unit were at higher risk of burnout (odds ratio (OR), 6.7; 95% CI, 1.1-42.1; p = 0.031). Of those who engaged in care of COVID-19 patients, 50% reported burnout while 6.1% did not (OR 8.5, 95% CI; 1.3-54.1; p = 0.014). The burnout of healthcare workers is a significant concern amid the pandemic, which needs to be addressed for sustainable healthcare delivery.

en-abstract=
kn-abstract=To clarify the relevance of prolactin (PRL) to clinical parameters in patients who visited our general medicine department, medical records of 353 patients in whom serum PRL levels were measured during the period from 2016 to 2018 were retrospectively reviewed. Data for 140 patients (M/F: 42/98) were analyzed after excluding patients lacking detailed records and patients taking dopaminergic agents. Median serum PRL levels were significantly lower in males than females: 6.5 ng/ml (IQR: 4.2-10.3) versus 8.1 ng/ml (5.9-12.9), respectively. Pain and general fatigue were the major symptoms at the first visit, and past histories of hypertension and dyslipidemia were frequent. Male patients with relatively high PRL levels (? 10 ng/ml) had significantly lower levels of serum albumin and significantly higher levels of serum LDH than those with low PRL (< 10 ng/ml). There were significant correlations of male PRL level with the erythrocyte sedimentation rate (R=0.62), serum LDH level (R=0.39) and serum albumin level (R=?0.52), while the level of serum CRP (R=0.33) showed an insignificant but weak positive correlation with PRL level. Collectively, these results show that PRL levels had gender-specific relevance to various clinical factors, with PRL levels in males being significantly related to inflammatory status.

kn-title=Antibiotic literacy among Japanese medical students
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Antimicrobial resistance (AMR) is an urgent global issue. After the AMR action plan was introduced in 2016, a study on antibiotic literacy (i.e., awareness, knowledge, and attitude relating to antimicrobial use) among clinicians and lay people was conducted in Japan. However, no studies have hitherto targeted medical students who are expected to have a high level of antibiotic literacy. The present study was conducted between September 2019 and February 2020, enrolling undergraduate students at Okayama University Medical School. We collected data using a paper-based questionnaire form with 11 questions about antibiotic literacy. The response rate was 93.8% (661/705 students). Overall, 92.6% of the students knew that antibiotics inhibit the growth of bacteria. Student reporting that antibiotics could treat the common cold accounted for 77.0% (Year 1), 50.9% (Year 2), 48.2% (Year 3), 49.1% (Year 4), 23.8% (Year 5), and 26.2% (Year 6). Only 43 (6.5%) had heard about the AMR action plan. The study data suggested that medical students' level of literacy on antimicrobial use should be further enhanced to address AMR and promote antimicrobial stewardship.

kn-title=Effects on postgraduate-year-I residents of simulation-based learning compared to traditional lecture-style education led by postgraduate-year-II residents: a pilot study
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=BACKGROUND:
Simulation-based learning plays an important role in contemporary medical education, although there are problems providing tutors. Peer-assisted learning has begun being formally adopted in medical education. Although it is considered useful for simulation-based learning, its effectiveness remains unclear. This study was designed to compare the effect of simulation-based learning with that of traditional lectures conducted by postgraduate-year (PGY)-II residents on PGY-I residents.
METHODS:
This study was conducted at Okayama University Hospital over three years, for one week each year, before residents entered clinical practice. The study enrolled 76 PGY-I residents, who were randomized into two groups: simulation and lecture groups. PGY-II residents volunteered to conduct simulations and lectures. Knowledge evaluation was performed using pre- and post-tests, and self-evaluation of competence and behaviour-change and program evaluations were conducted using questionnaires.
RESULTS:
In both groups, knowledge test scores were found to improve significantly, and the score difference between pre- and post-tests in both the groups was not significant. Self-evaluation of competence and behaviour-change was found to be higher in the simulation group than the lecture group. The trainees in the simulation group valued the program and the PGY-II residents as teaching staff more than those in the lecture group.
CONCLUSIONS:
The combination of simulation-based learning and peer-assisted learning led by PGY-II residents is potentially more effective in improving the postgraduate education of PGY-I residents than the combination of lecture and peer-assisted learning.

kn-abstract=Recent studies have suggested possible adverse effects of thiazolidinediones on bone metabolism. However, the detailed mechanism by which the activity of PPAR affects bone formation has not been elucidated. Impaired osteoblastic function due to cytokines is critical for the progression of inflammatory bone diseases. In the present study, we investigated the cellular mechanism by which PPAR actions interact with osteoblast differentiation regulated by BMP and TNF-alpha using mouse myoblastic C2C12 cells. BMP-2 and -4 potently induced the expression of various bone differentiation markers including Runx2, osteocalcin, type-1 collagen and alkaline phosphatase (ALP) in C2C12 cells. When administered in combination with a PPAR alpha agonist (fenofibric acid) but not with a PPAR gamma agonist (pioglitazone), BMP-4 enhanced osteoblast differentiation through the activity of PPAR alpha. The osteoblastic changes induced by BMP-4 were readily suppressed by treatment with TNF-alpha. Interestingly, the activities of PPAR alpha and PPAR gamma agonists reversed the suppression by TNF-alpha of osteoblast differentiation induced by BMP-4. Furthermore, TNF-alpha-induced phosphorylation of MAPKs, NF kappa B, I kappa B and Stat pathways was inhibited in the presence of PPAR alpha and PPAR gamma agonists with reducing TNF-alpha receptor expression. In view of the finding that inhibition of SAPK/JNK. Stat and NF kappa B pathways reversed the TNF-alpha suppression of osteoblast differentiation, we conclude that these cascades are functionally involved in the actions of PPARs that antagonize TNF-alpha-induced suppression of osteoblast differentiation. It was further discovered that the PPAR alpha agonist enhanced BMP-4-induced Smad1/5/8 signaling through downregulation of inhibitory Smad6/7 expression, whereas the PPAR gamma agonist impaired this activity by suppressing BMPRII expression. On the other hand, BMPs increased the expression levels of PPAR alpha and PPAR gamma in the process of osteoblast differentiation. Thus, PPAR alpha actions promote BMP-induced osteoblast differentiation, while both activities of PPAR alpha and PPAR gamma suppress TNF-alpha actions. Collectively, our present data establishes that PPAR activities are functionally involved in modulating the interaction between the BMP system and TNF-alpha receptor signaling that is crucial for bone metabolism.

kn-title=Activities of bone morphogenetic proteins in prolactin regulation by somatostatin analogs in rat pituitary GH3 cells
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Involvement of the pituitary BMP system in the modulation of prolactin (PRL) secretion regulated by somatostatin analogs, including octreotide (OCT) and pasireotide (SOM230), and a dopamine agonist, bromocriptine (BRC), was examined in GH3 cells. GH3 cells are rat pituitary somato-lactotrope tumor cells that express somatostatin receptors (SSTRs) and BMP system molecules including BMP-4 and -6. Treatment with BMP-4 and -6 increased PRL and cAMP secretion by GH3 cells. The BMP-4 effects were neutralized by adding a BMP-binding protein Noggin. These findings suggest the activity of endogenous BMPs in augmenting PRL secretion by GH3 cells. BRC and SOM230 reduced PRL secretion, but OCT failed to reduce the PRL level. In GH3 cells activated by forskolin, BRC suppressed forskolin-induced PRL secretion with reduction in cAMP levels. OCT did not affect forskolin-induced PRL level, while SOM230 reduced PRL secretion and PRL mRNA expression induced by forskolin. BMP-4 treatment enhanced the reducing effect of SOM230 on forskolin-induced PRL level while BMP-4 did not affect the effects of OCT or BRC. Noggin treatment had no significant effect on the BRC actions reducing PRL levels by GH3 cells. However, in the presence of Noggin, OCT elicited an inhibitory effect on forskolin-induced PRL secretion and PRL mRNA expression, whereas the SOM230 effect on PRL reduction was in turn impaired. It was further found that BMP-4 and -6 suppressed SSTR-2 but increased SSTR-5 mRNA expression of GH3 cells. These findings indicate that Noggin rescues SSTR-2 but downregulates SSTR-5 by neutralizing endogenous BMP actions, leading to an increase in OCT sensitivity and a decrease in SOM230 sensitivity of GH3 cells. In addition, BMP signaling was facilitated in GH3 cells treated with forskolin. Collectively, these findings suggest that BMPs elicit differential actions in the regulation of PRL release dependent on cellular cAMP-PKA activity. BMPs may play a key role in the modulation of SSTR sensitivity of somato-lactotrope cells in an autocrine/paracrine manner.

Circulating aldosterone concentrations occasionally increase after initial suppression with angiotensin II (Ang II) converting enzyme inhibitors or Ang II type 1 receptor blockers (ARBs), a phenomenon referred to as aldosterone breakthrough. However, the underlying mechanism causing the aldosterone breakthrough remains unknown. Here we investigated whether aldosterone breakthrough occurs in human adrenocortical H295R cells in vitro. We recently reported that bone morphogenetic protein (BMP)-6, which is expressed in adrenocortical cells, enhances Ang II-but not potassium-induced aldosterone production in human adrenocortical cells. Accordingly, we examined the roles of BMP-6 in aldosterone breakthrough induced by long-term treatment with ARB. Ang II stimulated aldosterone production by adrenocortical cells. This Ang II stimulation was blocked by an ARB, candesartan. Interestingly, the candesartan effects on Ang II-induced aldosterone synthesis and CYP11B2 expression were attenuated in a course of candesartan treatment for 15 d. The impairment of candesartan effects on Ang II-induced aldosterone production was also observed in Ang II- or candesartanpretreated cells. Levels of Ang II type 1 receptor mRNA were not changed by chronic candesartan treatment. However, BMP-6 enhancement of Ang II- induced ERK1/2 signaling was resistant to candesartan. The BMP-6-induced Smad1, -5, and -8 phosphorylation, and BRE-Luc activity was augmented in the presence of Ang II and candesartan in the chronic phase. Chronic Ang II exposure decreased cellular expression levels of BMP-6 and its receptors activin receptor-like kinase-2 and activin type II receptor mRNAs. Cotreatment with candesartan reversed the inhibitory effects of Ang II on the expression levels of these mRNAs. The breakthrough phenomenon was attenuated by neutralization of endogenous BMP-6 and activin receptor-like kinase-2. Collectively, these data suggest that changes in BMP-6 availability and response may be involved in the occurrence of cellular escape from aldosterone suppression under chronic treatment with ARB.

Histologically, infiltrations of IgG4-positive plasma cells and lymphocytes occur in the lacrimal gland, salivary gland , retroperitoneum , pancreas , and biliary tract. IgG4-related disease is a systematic disease presenting symptoms such as Mikulicz's disease, retroperitoneal fibrosis, autoimmune pancreatitis, diabetes and sclerotic cholangitis, and oral steroid therapy is effective. In this paper, we propose diagnostic criteria for IgG4-related disease that have not been established yet. If two (or more) of three following features are fulfilled, IgG4-related disease is diagnosed ; elevated levels of serum IgG4, involvement of organs which is characteristic in IgG4-related disease (salivary gland, lacrimal gland, pancreas and retroperitonium) ,histological findings with IgG4-positive plasma cells and lymphocytes. kn-abstract=IgG4関連疾患は21世紀になって提唱された新しい疾患である。組織学的にはIgG4陽性形質細胞やリンパ球浸潤が涙腺, 唾液腺, 後腹膜, 膵臓, 胆管などで起こり, 臨床的にはMikulicz病, 後腹膜線維症, 自己免疫膵炎, 糖尿病, 原発性硬化性胆管炎類似の胆管病変などを呈する全身性疾患であり, ステロイド治療に対する良好な反応性を認める。その診断基準は確立されておらず, われわれは, @血清IgG4の高値, A本疾患に特徴的な臓器の障害(唾液腺,涙腺, 膵臓, 後腹膜), B組織学的にIgG4陽性形質細胞とリンパ球の浸潤の確認, の3項目のうち2項目以上認めれば, IgG4関連疾患とするという診断基準を提言する。 en-copyright= kn-copyright= en-aut-name=HiramatsuKazuhisa en-aut-sei=Hiramatsu en-aut-mei=Kazuhisa kn-aut-name=平松万尚 kn-aut-sei=平松 kn-aut-mei=万尚 aut-affil-num=1 ORCID= en-aut-name=AsanoMotoi en-aut-sei=Asano en-aut-mei=Motoi kn-aut-name=浅野基 kn-aut-sei=浅野 kn-aut-mei=基 aut-affil-num=2 ORCID= en-aut-name=MatsushitaKoki en-aut-sei=Matsushita en-aut-mei=Koki kn-aut-name=松下公紀 kn-aut-sei=松下 kn-aut-mei=公紀 aut-affil-num=3 ORCID= en-aut-name=MiyoshiTomoko en-aut-sei=Miyoshi en-aut-mei=Tomoko kn-aut-name=三好智子 kn-aut-sei=三好 kn-aut-mei=智子 aut-affil-num=4 ORCID= en-aut-name=NakamuraSukio en-aut-sei=Nakamura en-aut-mei=Sukio kn-aut-name=中村好男 kn-aut-sei=中村 kn-aut-mei=好男 aut-affil-num=5 ORCID= en-aut-name=MizushimaTakaaki en-aut-sei=Mizushima en-aut-mei=Takaaki kn-aut-name=水島孝明 kn-aut-sei=水島 kn-aut-mei=孝明 aut-affil-num=6 ORCID= en-aut-name=KoideNorio en-aut-sei=Koide en-aut-mei=Norio kn-aut-name=小出典男 kn-aut-sei=小出 kn-aut-mei=典男 aut-affil-num=7 ORCID= en-aut-name=KataokaHitomi en-aut-sei=Kataoka en-aut-mei=Hitomi kn-aut-name=片岡仁美 kn-aut-sei=片岡 kn-aut-mei=仁美 aut-affil-num=8 ORCID= en-aut-name=OchiKoji en-aut-sei=Ochi en-aut-mei=Koji kn-aut-name=越智浩二 kn-aut-sei=越智 kn-aut-mei=浩二 aut-affil-num=9 ORCID= en-aut-name=MitsunobuFumihiro en-aut-sei=Mitsunobu en-aut-mei=Fumihiro kn-aut-name=光延文裕 kn-aut-sei=光延 kn-aut-mei=文裕 aut-affil-num=10 ORCID= affil-num=1 en-affil= kn-affil=岡山大学病院総合診療内科 affil-num=2 en-affil= kn-affil=岡山大学病院総合診療内科 affil-num=3 en-affil= kn-affil=岡山大学病院総合診療内科 affil-num=4 en-affil= kn-affil=岡山大学病院総合診療内科 affil-num=5 en-affil= kn-affil=岡山大学病院総合診療内科 affil-num=6 en-affil= kn-affil=岡山大学病院総合診療内科 affil-num=7 en-affil= kn-affil=岡山大学病院総合診療内科 affil-num=8 en-affil= kn-affil=岡山大学医療教育統合開発センター affil-num=9 en-affil= kn-affil=岡山大学医療教育統合開発センター affil-num=10 en-affil= kn-affil=岡山大学病院三朝医療センター en-keyword=IgG4関連疾患 (IgG4-related disease) kn-keyword=IgG4関連疾患 (IgG4-related disease) en-keyword=自己免疫膵炎 (autoimmune pancreatitis) kn-keyword=自己免疫膵炎 (autoimmune pancreatitis) en-keyword=Mikulicz病 (Mikulicz's disease) kn-keyword=Mikulicz病 (Mikulicz's disease) en-keyword=後腹膜線維症 (retroperitoneal fibrosis) kn-keyword=後腹膜線維症 (retroperitoneal fibrosis) END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2006 dt-pub=20060930 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=FSHシグナルによる卵巣BMPシステムへの新しい調節機構 :ヒト卵巣顆粒膜細胞を用いた検討 kn-title=Mutual Regulation of Follicle-Stimulating Hormone Signaling and Bone Morphogenetic Protein System in Human Granulosa Cells en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=MiyoshiTomoko en-aut-sei=Miyoshi en-aut-mei=Tomoko kn-aut-name=三好智子 kn-aut-sei=三好 kn-aut-mei=智子 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 END
