Introduction: Currently, there is confusion about what constitutes medical professionalism in Japan.　Method: We compared the histories of the development professionalism in western countries and Japan based on the stage theory of economic development and a literature review. Using the information we gathered, we discuss the reasons why the confusion occurred.　Result: In most of western countries, medical professionalism was affected by the industrial revolution and Protestantism. As Weber noted, for Protestants, working industriously and using the gift of one’s talent to earn much money was consistent with the teachings of God. Thus, reward was an important proof of their faith. Meanwhile, the Japanese social system and professionalism were developed independently from the industrial revolution. Since Japan was less influenced by the industrial revolution, knowledge was not subdivided. This resulted in undeveloped specialist jobs and the continuation of classical education based on Buddhism and Confucianism. Japanese professionalism, which included sacrificial altruism, differed from western professionalism, particularly with regard to the concept of reward.　Discussion: Due to globalization, Japanese society now has two types of professionalism: one from western ideals and another from classical Japanese ideals. Because these two types of professionalism conflict on certain points, such as the concept of reward, there is confusion about what constitutes Japanese professionalism.

We are engaged in community medical education using Minami-Hiyama (14,000km², population 23,000, aging rate 41.6%) in southern Hokkaido as a resource. The “rural(region)” concept has become more diverse in recent years, and a highly designed physician training program for rural doctors has become necessary. Therefore, we are attempting to design a rural medical education program based on the concept of “difference.” These “differences” can occur not only between urban and rural areas but also between different cultures. We hope that by connecting Minami-Hiyama and Sapporo with a telemedicine/education system, “differences” will be created and students who experience these differences will have a deeper understanding of rural medicine.

Patients with focal hand dystonia demonstrate abnormally increased corticospinal excitability, which has been reported to be ameliorated, at least for a short term, with low frequency repetitive transcranial magnetic stimulation (rTMS). Transcranial direct current stimulation (tDCS), which is less costly and easier to apply than rTMS, is also known to modulate cortical excitability. Especially with cathodal tDCS, cortical excitability can be reduced. On the other hand, upper extremity splinting is also known to reduce dystonic symptoms by inhibiting abnormal movement. We therefore combined cathodal tDCS with finger splinting to treat focal hand dystonia in a 34-year-old man with traumatic brain injury who showed involuntary movement of his right fingers during writing and chopsticks use. After 5 days of cathodal tDCS sessions (1mA, 10min), he was encouraged to use interphalangeal joint splints for his thumb and index finger during these activities. We assessed computer-rated handwriting, reciprocal inhibition and intracortical inhibition before, 24 hours and 3 months after the 5-day tDCS sessions. Before the treatment, his flexor pollicis longus (FPL) and first dorsal interosseous (FDI) muscles showed 4Hz rhythmic hyperactivity during writing, and reciprocal inhibition at interstimulus intervals (ISI) of 20 and 100 ms were lost. Paired pulse TMS also revealed disinhibited short interval intracortical inhibition (SICI) at an ISI of 2 and 3 ms. The 5-day tDCS sessions reduced FPL and FDI EMG activities, and SICI and RI at 20 and 100 ms were also restored. Wearing the finger splints, these improvements were maintained at the 3-month follow-up. This case report is the first to demonstrate the possible long-term effects of tDCS combined with splinting for focal hand dystonia. It is supposed that splinting after tDCS plays an important role in making the tDCS aftereffects last longer.

Behcet's disease (BD) is a systemic vasculitis, while myelodysplastic syndrome (MDS) is a heterogeneous group of clonal hematologic disorders characterized by ineffective hematopoiesis. Some studies suggest a relationship between MDS and BD, especially intestinal BD, and trisomy 8 seems to play an important role in both diseases. There are several reports on patients with BD comorbid with MDS involving trisomy 8 that frequently have intestinal lesions refractory to conventional medical therapies. Tumor necrosis factor (TNF)-alpha is strongly involved in the pathophysiology of several autoimmune diseases such as rheumatoid arthritis, inflammatory bowel disease, and BD. In addition, TNF-alpha plays an important role in the pathophysiology of MDS by inhibiting normal hematopoiesis and inducing the programmed cell death of normal total bone marrow cells and normal CD34+ cells. Recent clinical reports demonstrate the favorable effect of TNF-alpha antagonists in patients with refractory intestinal BD and in those with MDS. We present the case of a patient with intestinal BD and MDS involving trisomy 8 who was successfully treated with adalimumab.

Background: The impact of COVID-19 infection on workers' work function persists even after the acute phase of the infection. We studied this phenomenon in Japanese workers. Methods: We conducted a one-year prospective cohort study online, starting with a baseline survey in December 2020. We tracked workers without baseline work functioning impairment and incorporated data from 14,421 eligible individuals into the analysis. We estimated the incidence rate ratio for new onset of work functioning impairment due to COVID-19 infection during follow-up, using mixed-effects Poisson regression analysis with robust variance. Results: Participants reporting infection between January and December 2021 showed a significantly higher incidence of new work functioning impairment (adjusted incidence rate ratio: 2.18, 95% confidence interval: 1.75–2.71, p < 0.001). The formality of the recuperation environment correlated with a higher risk of work functioning deterioration in infected individuals (p for trend <0.001). Conclusion COVID-19-infected workers may continue to experience work difficulties due to persistent, post-acute infection symptoms. Companies and society must urgently provide rehabilitation and social support for people with persistent symptoms, recognizing that COVID-19 is not just a transient acute infection.

BACKGROUND: It is important to achieve herd immunity by vaccinating as many people as possible to end the COVID-19 pandemic. We investigated the relationship between willingness to receive vaccination and sources of health information among those who did not want to be vaccinated against COVID-19. METHODS: This prospective cohort study collected data using a self-administered questionnaire survey. The baseline survey was conducted during December 22-25, 2020, and the follow-up survey during February 18-19, 2021. Participants were aged 20-65 years and worked at the time of the baseline survey (N = 33,087). After excluding 6,051 invalid responses, we included responses from 27,036 participants at baseline. In total, 19,941 people responded to the follow-up survey (74% follow-up rate). We excluded 7,415 participants who answered "yes" to the question "If a COVID-19 vaccine becomes available, would you like to get it?" in the baseline survey. We finally analyzed 12,526 participants. RESULTS: The odds ratio for change in willingness to be vaccinated from "no" to "yes" differed by source of health information. Compared with workers that used TV as a source of information, significantly fewer people who reported getting information from the Internet and friends/colleagues were willing to get the vaccine. CONCLUSIONS: It is important to approach workers who do not watch TV when implementing workplace vaccination programs. It is likely that willingness to be vaccinated can be increased through an active company policy whereby the top management recommend vaccination, coupled with an individual approach by occupational health professionals.

BACKGROUND: To combat coronavirus disease 2019 (COVID-19), many countries have used contact tracing apps, including Japan's voluntary-use contact-confirming application (COCOA). The current study aimed to identify industry and workplace characteristics associated with the downloading of this COVID-19 contact tracing app. METHODS: This cross-sectional study of full-time workers used an online survey. Multiple logistic regression analysis was used to evaluate the associations of industry and workplace characteristics with contact tracing app use. RESULTS: Of the 27,036 participants, 25.1% had downloaded the COCOA. Workers in the public service (adjusted odds ratio [aOR] = 1.29, 95% confidence interval [CI] 1.14-1.45) and information technology (aOR = 1.38, 95% CI 1.20-1.58) industries were more likely to use the app than were those in the manufacturing industry. In contrast, app usage was less common among workers in the retail and wholesale (aOR = 0.87, 95% CI 0.76-0.99) and food/beverage (aOR = 0.81, 95% CI 0.70-0.94) industries, but further adjustment for company size attenuated these associations. Workers at larger companies were more likely to use the app. Compared with permanent employees, the odds of using the app were higher for managers and civil servants but lower for those who were self-employed. CONCLUSIONS Downloading of COCOA among Japanese workers was insufficient; thus, the mitigating effect of COCOA on the COVID-19 pandemic is considered to be limited. One possible reason for the under-implementation of the contact tracing app in the retail and wholesale and food/beverage industries is small company size, as suggested by the fully adjusted model results. An awareness campaign should be conducted to promote the widespread use of the contact tracing app in these industries.
