The mGPS, PNI, and NLR were effective predictive indicators of postoperative complications. The PLR was the most useful prognostic indicator for pancreatic cancer patients after pancreaticoduodenectomy.
This study aimed to evaluate disease and injury trends among wintering members of the Japanese Antarctic Research Expedition. Obtained information is indispensable to the advancement of medical system and research. Summation was performed based on medical records of reports prepared by each expedition over the period 1956–2016. The clinical department’s classification methods of the names of injuries and diseases varied among expeditions, but the names were integrated following the same classification. Of 1734 members (29 women), 6837 disease or injury cases (4 cases/person) were recorded. The rates of cases were as follows: surgical-orthopaedic (45.3%), internal medical (21.7%), dental (11.6%), dermatological (8.4%), ophthalmological (5.8%), otorhinolaryngological (5.3%), psychiatric (1.6%), and urological (0.1%) cases. There was no major change in rates by type of medical case in each expedition. This analysis made it possible to prepare medical facilities, content of physical examinations to select members, training of physicians before departure, preventive hygiene at sites, and medical research themes.
The occurrence of Asian dust events is a frequent problem, with associated health issues throughout Northeast Asia. However, the effects of Asian dust on human health are not well known in Japan. The authors evaluated the association between daily symptoms and dust events in Yonago, Japan. The subjects were 54 healthy individuals who were distributed survey sheets on nasopharyngeal, ocular, respiratory, and skin symptoms, which were quantified in February 2009. The authors investigated the symptoms of the subjects on Asian dust days and control days, and compared the symptom scores with measures of suspended particulate matter (SPM), which is the indicator of Asian dust. The scores for symptoms were significantly higher on Asian dust days than on control days (p=.020). The skin symptom scores were positively correlated with the SPM level (p<.001). These results provide preliminary evidence that Asian dust influence the symptoms of healthy subjects, although the symptoms are not severe.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
