RESUMEN
AIMS: This study aimed to evaluate the long-term results of Japan Maternal Emergency Life-Saving (J-MELS) simulation training on obstetric healthcare providers, over a 12-month follow-up period. METHODS: A total of 273 trainees from 17 J-MELS Basic courses conducted between August 2021 and October 2023 were included. The trainees' responses to the pre- and post-tests, questionnaires, and self-reports on the usefulness of the J-MELS scenarios in actual clinical settings at 1, 6, and 12 months after the training were analyzed. Multivariate logistic regression analysis was also conducted to identify the factors influencing knowledge retention. RESULTS: We found an overall improvement in clinical knowledge acquisition after J-MELS training and a significant retention of this improvement at least until 12 months later. However, these scores gradually declined over. Trainees reported increased usefulness of J-MELS scenarios in actual clinical practice at 1, 6, and 12 months after training, particularly in managing obstetric emergencies such as atonic postpartum hemorrhage. Knowledge retention was influenced by several specific factors, such as years of clinical experience, affiliated institutions, qualifications, and especially pre-test scores. CONCLUSION: Our longitudinal follow-up study demonstrated, for the first time, the long-term results of J-MELS simulation training using post-tests and self-report data. Our findings provide valuable insight into the impact of J-MELS simulation training on maternal emergency care. By elucidating the factors influencing knowledge retention and practical utility, the findings offer actionable recommendations for optimizing training strategies and improving maternal outcomes in actual clinical practice.
RESUMEN
The perinatal resuscitation history in Japan is short, with the earliest efforts in the field of neonatology. In contrast, the standardization and dissemination of maternal resuscitation is lagging. With the establishment of the Maternal Death Reporting Project and the Maternal Death Case Review and Evaluation Committee in 2010, with the aim of reducing maternal deaths, the true situation of maternal deaths came to light. Subsequently, in 2015, the Japan Council for the Dissemination of Maternal Emergency Life Support Systems (J-CIMELS) was established to educate and disseminate simulations in maternal emergency care; training sessions on maternal resuscitation are now conducted in all prefectures. Since the launch of the project and council, the maternal mortality rate in Japan (especially due to obstetric critical hemorrhage) has gradually decreased. This has been probably achieved due to the tireless efforts of medical personnel involved in perinatal care, as well as the various activities conducted so far. However, there are no standardized guidelines for maternal resuscitation yet. Therefore, a committee was set up within the Japan Resuscitation Council to develop a maternal resuscitation protocol, and the Guidelines for Maternal Resuscitation 2020 was created in 2021. These guidelines are expected to make the use of high-quality resuscitation methods more widespread than ever before. This presentation will provide an overview of the Guidelines for Maternal Resuscitation 2020.

Myasthenia gravis (MG) is an autoimmune disease and represents one of the most common disorders associated with neuromuscular transmission defects. Within MG, the anti-muscle-specific kinase antibody-positive subtype (MuSK-positive MG) is rare. While it shares similarities with the common form of MG by presenting with ocular weakness, MuSK-positive MG typically presents with more atypical symptoms. Although MuSK-positive MG can lead to type 2 respiratory failure due to respiratory weakness, there have been limited reports where initial presentation involves only respiratory compromise. This study details a case of MuSK-positive MG presenting dyspnea. An 84-year-old female presented to the emergency department due to a three-day history of progressive respiratory distress, characterized by increased respiratory effort and shallow breathing, resulting in a diagnosis of type 2 respiratory failure. Despite the absence of neurological abnormalities, she tested positive for anti-muscle-specific kinase antibodies, confirming a diagnosis of MuSK-positive MG. This case highlights the significance of considering MG in the context of type 2 respiratory failure, even in the absence of typical neurological symptoms, especially in elderly patients.
RESUMEN
Hospital-at-home (HaH) care is useful for patients with COVID-19 and an alternative strategy when hospital capacity is under pressure due to patient surges. However, the efficacy and safety of HaH in elderly patients with COVID-19 remain unknown. In Kyoto city, we conducted a retrospective medical record review of HaH care focused on elderly COVID-19 patients from 4 February to 25 June 2021. Eligible patients were (1) COVID-19 patients aged ≥70 years and those who lived with them or (2) COVID-19 patients aged <70 years with special circumstances and those who lived with them. During the study period, 100 patients received HaH care. Their median age was 76 years (interquartile range 56−83), and 65% were over 70 years. Among 100 patients, 36 (36%) had hypoxia (oxygen saturation ≤ 92%), 21 (21%) received steroid medication, and 34 (34%) received intravenous fluids. Although 22 patients were admitted to the hospital and 3 patients died there, no patients died during HaH care. HaH care may be safe and effective in elderly patients with COVID-19. Our study shows that HaH provides an alternative strategy for treating COVID-19 patients and can reduce the healthcare burden at hospitals.
RESUMEN
BACKGROUND: Japan implemented a large-scale quarantine on the Diamond Princess cruise ship in an attempt to control the spread of the novel coronavirus severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in February 2020. OBJECTIVE: We aim to describe the medical activities initiated and difficulties in implementing quarantine on a cruise ship. METHODS: Reverse transcription-polymerase chain reaction (RT-PCR) tests for SARS-CoV-2 were performed for all 3711 people (2666 passengers and 1045 crew) on board. RESULTS: Of those tested, 696 (18.8%) tested positive for coronavirus disease (COVID-19), of which 410 (58.9%) were asymptomatic. We also confirmed that 54% of the asymptomatic patients with a positive RT-PCR result had lung opacities on chest computed tomography. There were many difficulties in implementing quarantine, such as creating a dividing traffic line between infectious and noninfectious passengers, finding hospitals and transportation providers willing to accept these patients, transporting individuals, language barriers, and supporting daily life. As of March 8, 2020, 31 patients (4.5% of patients with positive RT-PCR results) were hospitalized and required ventilator support or intensive care, and 7 patients (1.0% of patients with positive RT-PCR results) had died. CONCLUSIONS: There were several difficulties in implementing large-scale quarantine and obtaining medical support on the cruise ship. In the future, we need to prepare for patients' transfer and the admitting hospitals when disembarking the passengers. We recommend treating the crew the same way as the passengers to control the infection. We must also draw a plan for the future, to protect travelers and passengers from emerging infectious diseases on cruise ships.

Motor vehicle accidents (MVAs) are one of the major public health burdens worldwide. In particular, MVAs by elderly drivers have been significantly increasing in recent years in industrialized countries. This study aimed to assess the MVA characteristics and outcomes caused by elderly drivers in Japan.Japan Trauma Data Bank (JTDB) is a prospective, nationwide, hospital-based registry for trauma patients from 256 institutions in Japan. This study enrolled all MVA drivers older than the legal age for driving between 2004 and 2015. The included patients were divided into the following 3 groups: adults (aged ≤64 years), young-old (aged 65-74 years), and old-old (aged ≥75 years). The primary outcome was in-hospital mortality. The trend in the proportion of MVAs caused by the young-old or the old-old group was evaluated using the Cochran-Armitage trend test. To assess the association of the old-old group with in-hospital mortality, compared with the adult group, we used multivariable logistic regression analysis.During the study period, a total of 236,698 trauma patients were registered, and 39,691 patients (16.8%) were eligible for our analysis. The proportion of MVAs caused by elderly drivers aged ≥65 years significantly increased from 11.7% in 2004 to 23.8% in 2015 (Pâ<â.001). As for the primary outcome, unadjusted in-hospital mortality increased with age, but decreased year-by-year irrespective of the age group. In multivariable logistic regression analysis, in-hospital mortality was significantly higher in the old-old group than in the adult group [17.3% (584/3372) vs 8.0% (2556/31,985); adjusted odds ratio 4.80; 95% confidence interval 4.06-5.67].In the super-aging society of Japan, the proportion of MVAs by elderly drivers increased year-by-year, and the mortality rate was highest in those aged above 75 years.

BACKGROUND: In 2017, the Japanese government published an evidence-based manual describing the appropriate use of antibiotics in outpatient settings to tackle the problem of antimicrobial resistance. To fill the evidence-practice gap, we developed a clinician-targeted course aimed at improving clinician skills in the daily clinical practice of treating acute respiratory tract infections (RTIs) based on the manual. The aim of this study was to evaluate the efficacy of the course. METHODS: This course consisted of lectures using illness scripts and checklists, as well as interactive communication skills training using role-playing. We performed a vignette-based evaluation of the changes in the knowledge and attitudes of the course participants toward prescribing antibiotics for nonpneumonia RTIs, using pre- and postcourse questionnaires. The questionnaires also included course feedback via the use of a 5-point Likert scale. RESULTS: Thirty-eight clinicians were included in the analyses, and 90% of these participants had graduated ≥20 years ago. We found statistically significant reductions in the intention to prescribe antibiotics for four of the six nonpneumonia RTI vignettes: acute bronchitis (-47.2%; 95% confidence interval [CI] -66.3 to -28.1%), common cold (-16.2%; 95% CI -30.8 to -1.6%), acute pharyngitis (-27.0%; 95% CI -49.0 to -5.0%), and acute rhinosinusitis (-33.3%; 95% CI -53.3 to -13.3%). The course seemed to be satisfactory for experienced doctors who were the relevant target population of such a workshop. CONCLUSIONS: The refresher course was helpful for reducing the participants' intensions to prescribe antibiotics for nonpneumonia RTIs.
