Association between community medicine rotation duration and general medicine in-training examination scores among second-year resident physicians in Japan
Clinical competence and attitudes towards LGBT patients among medical residents in Japan
BACKGROUND: Sexual and gender minorities face persistent health disparities, partly due to the limited competence of healthcare providers in LGBT-inclusive care. Although education can improve these skills, little is known about LGBT-related competence in non-Western contexts such as Japan, where LGBT health content is scarcely integrated into medical curricula and visibility remains limited. METHODS: We conducted a nationwide cross-sectional stu…
Impact of scholarly activities on early postgraduate medical trainees
Nationwide survey of formal mentorship characteristics and perceptions among resident physicians in Japan
Association between resident physicians from foreign medical schools and general medicine in-training examination scores
Impact of inpatient volume on residents’ In-training examination scores and burnout in Japanese community hospitals
Association between grit and wellness outcomes among Japanese medical residents
PURPOSE: The well-being of resident physicians is a globally recognized concern, with high rates of burnout, stress, and attrition. Studies proposed grit-a personality trait defined as perseverance and passion for long-term goals-as a protective factor against poor psychological outcomes. Although studies in Western countries have linked grit with lower burnout and depression among residents, evidence from collectivist cultures, such as Japan, re…
A cross-sectional study on mental health and quality of life among LGBTQ+ individuals in Japan
Introduction: Studies from Western countries claim LGBTQ+ people face mental health burdens. It remains unclear in Japan. This study aimed to examine mental health challenges among LGBTQ+ individuals in Japan. Methods: JACSIS (Japan COVID-19 and Society Internet Survey) 2022 participants were categorized in cisgender-heterosexual, gay-identifying, lesbian-identifying, bisexual-identifying, questioning, transgender and nonbinary. Associations betw…
Variations and trends in major research topics across leading general medical journals, 1966–2022
Attention to publication diversity calls for broader topic inclusion by journals. Although general medical journals have distinct editorial policies, cross-journal differences remain underexplored. To compare trends of major research topics of clinical trials among leading general medical journals indexed in PubMed. A meta-research study was conducted for clinical trials in Lancet, NEJM, JAMA and BMJ from 1966 to 2022. Clinical trial numbers and …
Differences in the resident encounter of disruptive behavior by gender
This study aimed to investigate the prevalence of gender-based differences in disruptive behaviors (DBs) among trainee physicians to shed light on the extent and nature of the problem. Using a national cross-sectional design, data were collected through a web-based, self-administered questionnaire administered to post-graduate first-year (PGY1) and second-year (PGY2) residents participating in the General Medicine Intermittent Examination (GM-ITE…
Impact of the resident duty hours on in-training examination score
Purpose The relationship between duty hours (DH) and the performance of postgraduate residents is needed to establish appropriate DH limits. This study explores their relationship using the General Medicine In-training Examination (GM-ITE).Materials and methods In this cross-sectional study, GM-ITE examinees of 2019 had participated. We analyzed data from the examination and questionnaire, including DH per week (eight categories). We examined the…
Cognitive Bias and Diagnostic Errors among Physicians in Japan
This cross-sectional study aimed to clarify how cognitive biases and situational factors related to diagnostic errors among physicians. A self-reflection questionnaire survey on physicians' most memorable diagnostic error cases was conducted at seven conferences: one each in Okayama, Hiroshima, Matsue, Izumo City, and Osaka, and two in Tokyo. Among the 147 recruited participants, 130 completed and returned the questionnaires. We recruited primary…
Effects of Electrocardiographic Monitoring Education on Nurses’ Confidence and Psychological Stress
We aimed to investigate the association between nurses' electrocardiographic (ECG) monitoring education and their confidence and psychological stress regarding ECG monitoring. In 2019, a web-based cross-sectional study was conducted among Japanese nurses. A multivariable logistic regression analysis was performed to evaluate the effects of education on nurses' confidence and psychological stress regarding ECG monitoring. In total, 1652 nurses wer…
The Utility of Virtual Patient Simulations for Clinical Reasoning Education
Virtual Patient Simulations (VPSs) have been cited as a novel learning strategy, but there is little evidence that VPSs yield improvements in clinical reasoning skills and medical knowledge. This study aimed to clarify the effectiveness of VPSs for improving clinical reasoning skills among medical students, and to compare improvements in knowledge or clinical reasoning skills relevant to specific clinical scenarios. We enrolled 210 fourth-year me…

Constructing a New U.S. Military Base
Okinawa, a group of small islands between Japan and Taiwan and a formerly independent kingdom, has been the site of wars conducted by foreign armies for hundreds of years. Since World War II, the mainland of Okinawa has been the principal focus of the American military presence in Japan. The people of Okinawa experience a number of adverse health and environmental effects from U.S. military bases. Environmental effects include aircraft noise, asb…
Sex differences in the change in health-related quality of life associated with low back pain
Influence of Income on Health Status and Healthcare Utilization in Working Adults
Little is known about health of the growing subpopulation of the working poor in Japan. We aimed to evaluate health status and healthcare utilization in relation to income among Japanese working adults. We conducted a one-month prospective cohort study using a health diary in working adults from a nationally representative random sample in Japan. Based on the government criterion, the working poor group was defined as earning an equivalent annual…
