| Abstract | Few studies have investigated the influence of the Coronavirus Disease 2019 (COVID-19) pandemic on emer-gency medical service (EMS) systems, especially in areas less affected or unaffected by COVID-19. In this study, we investigated changes in prehospital EMS activity and transport times during the COVID-19 pandemic. All patients transported by EMS in the city of Okayama from March–May 2019 or March–May 2020 were included. Interfacility transports were excluded. The primary outcome was the time from a patient’s first emergency call until hospital arrival (total prehospital time). Secondary outcomes included three segments of total prehospital time: the response time, on-scene time, and transportation time. Total prehospital time and the durations of each segment were compared between corresponding months in 2020 (COVID19-affected) and 2019 (control). The results showed that total prehospital times in April 2020 were significantly higher than those in 2019 (33.8 ± 11.6 vs. 32.2 ± 10.8 min, p < 0.001). Increases in total prehospital time were caused by longer response time (9.3 ± 3.8 vs. 8.7 ± 3.7 min, p < 0.001) and on-scene time (14.4 ± 7.9 vs. 13.5 ± 6.2min, p < 0.001). The COVID-19 pandemic was thus shown to affect EMS and delayed arrival/response even in a minimally affected region. A system to minimize transportation delays should be developed for emerging pandemics. |

| Abstract | The importance of centralizing treatment services for severely ill children has been well established, but such entralization remains difficult in Japan. We aimed to compare the trauma and illness severity and mortality of children admitted to two common types of ICUs for children. According to the type of management and disposition of the medical provider, we classified ICUs as pediatric ICUs [PICUs] or general ICUs, and analyzed differences in endogenous and exogenous illness settings between them. Overall, 1,333 pediatric patients were included, with 1,143 patients admitted to PICUs and 190 patients to general ICUs. The Pediatric Cerebral Performance Category score (PCPC) at discharge was significantly lower in the PICU group (adjusted OR: 0.45; 95%CI: 0.23-0.88). Death and unfavorable neurological outcomes occurred less often in the PICU group (adjusted OR: 0.29; 95%CI: 0.14-0.60). However, when limited to exogenous illness, PCPC scores (adjusted OR: 0.38; 95%CI: 0.07-1.99) or death/unfavorable outcomes (adjusted OR: 0.72; 95%CI: 0.08-6.34) did not differ between the groups. PCPC deterioration and overall sequelae/death rates were lower in PICUs for children with endogenous illnesses, although the outcomes of exogenous illness were similar between the 2 unit types. Further studies on the necessity of centralization are warranted. |

| Abstract | Worldwide, hemorrhagic shock in major trauma remains a major potentially preventable cause of death. Controlling bleeding and subsequent coagulopathy is a big challenge. Immediate assessment of unidentified bleeding sources is essential in blunt trauma patients with hemorrhagic shock. Chest/pelvic X-ray in conjunction with ultrasonography have been established classically as initial diagnostic imaging modalities to identify the major sources of internal bleeding including intra-thoracic, intra-abdominal, or retroperitoneal hemorrhage related to pelvic fracture. Massive soft tissue injury, regardless of whether isolated or associated with multiple injuries, occasionally causes extensive hemorrhage and acute traumatic coagulopathy. Specific types of injuries, including soft tissue injury or retroperitoneal hemorrhage unrelated to pelvic fracture, can potentially be overlooked or be considered “occult” causes of bleeding because classical diagnostic imaging often cannot exclude such injuries. The purpose of this narrative review article is to describe “occult” or unusual sources of bleeding associated with blunt trauma. |

| Abstract | In recent years, it has become evident that molecular hydrogen is a particularyl effective treatment for various disease models such as ischemia-reperfusion injury; as a result, research on hydrogen has progressed rapidly. Hydrogen has been shown to be effective not only through intake as a gas, but also as a liquid medication taken orally, intravenously, or locally. Hydrogenʼs effectiveness is thus multifaceted. Herein we review the recent research on hydrogen-rich water, and we examine the possibilities for its clinical application. Now that hydrogen is in the limelight as a gaseous signaling molecule due to its potential ability to inhibit oxidative stress signaling, new research developments are highly anticipated. |

| Abstract | During major flooding in June/July 2018, the Mabi Memorial Hospital in Kurashiki, Okayama, Japan was flooded and patients were stranded in the hospital. Peace Winds Japan, a non-governmental organization, collaborated with the Japanese Disaster Medical Assistance Team and Self-Defense Force Public to transport 8 critical patients from the hospital by helicopter. Ultimately, 54 patients and hospital staff members were safely evacuated. The evacuation was accomplished without any casualties, despite the severe conditions. Public and private organizations can work together and continue to seek ways to collaborate and cooperate in disaster settings. |

| Abstract | Newly published clinical practice guidelines recommend intracranial pressure (ICP) monitoring in critical care for the management of pediatric acute encephalopathy (pAE), but the utility of ICP monitoring for pAE has been poorly studied. We recently performed direct ICP monitoring for two patients. We observed that although the direct ICP monitoring had clinical benefits with less body weight gain and no vasopressor use in both cases, this monitoring technique is still invasive. Future studies should determine the utility of non-invasive ICP monitoring systems in pAE to further improve the quality of intensive-care management. |
