Persistent fifth aortic arch has been thought to be rare but often relevant to systemic circulation, however when it connects to the pulmonary artery (PA) in pulmonary atresia, it may be the sole arterial supply to the lung. This report describes a case of rare arch anomaly including right aortic arch (RAA), PA sling in conjunction with persistent left fifth aortic arch (PLFAA) and left subclavian artery arising from the left fourth arch. The tetralogy of Fallot, pulmonary atresia, and total anomalous of pulmonary venous connection (cardiac) were also diagnosed. A neonate was referred to our hospital for surgical treatment of cardiac and extracardiac anomalies. Persistent fifth aortic arch connecting with pulmonary artery was initially thought to be patent ductus arteriosus (PDA), so prostaglandin E 1 administration was commenced. He underwent emergency colostomy for anal atresia. Subepiglottic tracheal stenosis was diagnosed at initiation of anesthesia. At age 1-month-old, he required systemic to pulmonary shunt and reimplantation of left pulmonary artery through a median sternotomy using extracorporeal circulation. At the operation the PDA was divided and oversewn, and the wall structure was the same as that of a normal artery. The left pulmonary artery behind trachea was dissected and we then cut away and reimplanted to pulmonary trunk. Tracheostomy was performed at the age of two months. With the technical development of diagnostic imaging, the morphological features of arch anomaly were clearly demonstrated, but some understanding of embryological aspects are still required for diagnosis.

Introduction :
This article aims to explain the new Membership of Royal College of General Practitioners (nMRCGP), new postgraduate general practice training in the UK. It will also compare this with that of the Japan Primary Care Association to identify areas requiring further development in postgraduate family medicine training in Japan.
Methods :
The introduction of the nMRCGP based on the available literature, followed by discussion amongst family physicians and trainees in Japan.
Results :
Following a comparison between the postgraduate general practice training in the UK and Japan, the following three points were raised : 1) The need for a clear definition of the role that family physicians play in Japan. 2) The importance of formative assessment as part of the membership examination in the form of portfolios. 3) The need for clear competency areas to form the framework for formative assessment, and for the clear standard that trainees are judged against in each of those competency areas.
Conclusion :
The above results were highlighted and discussed as possible areas for further development in postgraduate family medicine training in Japan.

Trauma-induced coagulopathy is classified into primary and secondary coagulopathy, with the former elicited by trauma and traumatic shock itself and the latter being acquired coagulopathy induced by anemia, hypothermia, acidosis, and dilution. Primary coagulopathy consists of disseminated intravascular coagulation and acute coagulopathy of trauma shock (ACOTS). The pathophysiology of ACOTS is the suppression of thrombin generation and neutralization of plasminogen activator inhibitor-1 mediated by activated protein C that leads to hypocoagulation and hyperfibrinolysis in the circulation. This review tried to clarify the validity of activated protein C hypothesis that constitutes the main pathophysiology of the ACOTS in experimental trauma models.

In 2021, the National Institute of Infectious Diseases, Japan, undertook enhanced event-based surveillance (EBS) for infectious diseases occurring overseas that have potential for importation (excluding coronavirus disease 2019 [COVID-19]) for the Tokyo 2020 Olympic and Paralympic Summer Games (the Games). The pre-existing EBS system was enhanced using the World Health Organization Epidemic Intelligence from Open Sources system and the BlueDot Epidemic Intelligence platform. The enhanced EBS before and during the Games did not detect any major public health event that would warrant action for the Games. However, information from multiple sources helped us identify events, characterize risk and improve confidence in risk assessment. The collaboration also reduced the surveillance workload of the host country, while ensuring the quality of surveillance, even during the COVID-19 pandemic.

The establishment of enhanced surveillance systems for mass gatherings to detect infectious diseases that may be imported during an event is recommended. The World Health Organization Regional Office for the Western Pacific contributed to enhanced event-based surveillance for the Tokyo 2020 Olympic and Paralympic Games (the Games) by using Epidemic Intelligence from Open Sources (EIOS) to detect potential imported diseases and report them to the National Institute of Infectious Diseases (NIID), Japan. Daily screening of media articles on global infectious diseases was conducted using EIOS, which were systematically assessed to determine the likelihood of disease importation, spread and significant impact to Japan during the Games. Over 81 days of surveillance, 103 830 articles were screened by EIOS, of which 5441 (5.2%) met the selection criteria for initial assessment, with 587 (0.6%) assessed as signals and reported to NIID. None of the signals were considered to pose a significant risk to the Games based on three risk assessment criteria. While EIOS successfully captured media articles on infectious diseases with a likelihood of importation to and spread in Japan, a significant manual effort was required to assess the articles for duplicates and against the risk assessment criteria. Continued improvement of artificial intelligence is recommended to reduce this effort.
