ABSTRACT
Although the risks faced by passengers in near-side lateral collisions are understood, and despite the presence of side airbags for injury prevention, passengers involved in far-side lateral collisions also suffer serious and fatal injuries. The objective of this study was to determine the independent predictive factors of fatality of motor vehicle passengers involved in far-side lateral collisions. Using 2010 records from the National Automotive Sampling System/Crashworthiness Data System (NASS/CDS), we selected 86 fatal and 325 non-fatal passengers with an Abbreviated Injury Scale (AIS) score of 2 or more. The background and injury severity of the passengers and collision characteristics were compared between the two groups. In a multivariable logistic regression analysis, variables independently associated with fatalities were female sex (Ref, male) (odds ratio [OR], 0.396), age (OR, 1.029), body mass index (OR, 1.057), total delta-V (OR, 1.031), head AIS score (OR, 1.679), chest AIS score (OR, 1.330), and abdomen AIS score (OR, 1.294). This is the first report to determine factors affecting fatality in passengers involved in far-side lateral collisions. Improving the safety of the vehicle interior, such as by including additional seatbelt systems or a side airbag that deploys between seats, might help to avoid fatalities, and reduce injury severity.
ABSTRACT
The Model Project for Child Death Review (CDR) was initiated in Japan, but parental consent is required for detailed investigations. We proposed an alternative method to review child deaths using death certificates and forensic autopsy results when parental consent is not provided. We extracted and reviewed death certificates for the deceased younger than 18 years from among all certificates submitted in Shiga Prefecture between 2015 and 2017. In addition, we analyzed autopsy records in cases that underwent forensic autopsy. The prevalence of each cause of death was compared among age groups. The situation and circumstances of unnatural deaths were analyzed in detail. Of 131 certificates, unnatural deaths accounted for 29.7 %. The prevalence of each cause of death significantly differed among age groups. Malignant disease and suicide were most common in school-aged children and congenital disease was most common in infants. Suicide was the leading cause of unnatural death, followed by suffocation, which was most common in infants. Situations where suffocation was reported included co-sleeping with the mother and breastfeeding. Despite parental consent not being obtained, the trends of regional child deaths and the circumstances of accidental deaths were clarified by the present method. However, the results of detailed investigation were lacking. This study provided basic information for implementing detailed methods and procedures for CDR at the governmental level. To perform optimal CDR, legislation for collecting detailed information without parental consent is required.

BACKGROUND: The Immediate Stroke Life Support (ISLS) course run in Wakayama (Wakayama-ISLS course) is an off-the-job training course for understanding the initial treatment of acute stroke. A total of 22 Wakayama-ISLS courses have been held in Wakayama Prefecture since 2008. To begin with, the case presentation was performed using human-like, mechanical manikins for simulation training. However, as the course progressed, we found the students paying great attention to the display monitor, and less to the patients' neurological status. METHODS: From the fourth Wakayama-ISLS course onward, we conducted the group work with the facilitators pretending to be patients, i.e., without medical training manikins. RESULTS: When the facilitators acted as patients, the students gained a more realistic and expressive perception of neurological symptoms. As a result, they expressed a high level of satisfaction with the course in the questionnaire sent immediately afterwards, regardless of their profession or prior experience. Moreover, as we did not need to transfer medical training simulators, we were able to carry out three ISLS courses at locations some distance from Wakayama city on a low-cost basis. This also enabled the regional medical staff in rural hospitals to participate in the courses easily. CONCLUSION: The Wakayama-ISLS course without medical training manikins is an entirely feasible off-the-job training course, which provides training on fast and excellent treatment of acute stroke problems based on clinical practice. The course has the potential to spread not only across Japan but throughout the world, including to developing countries, given the cost perspective.
