ABSTRACT
Objective To analyze the research status and trend of scarlet fever literature in China, and to provide reference for subsequent research. Methods Three major Chinese databases, CNKI, Wanfang, and VIP, as well as Web of Science English database, were used to search for literature related to scarlet fever from 2000 to 2023. Citespace6.2.R2 software was used to statistically analyze the number of publications, authors, institutions and journals, co-cited literature, keyword clustering, and other literature characteristics of the literature. Results From 2000 to 2023, a total of 1 011 Chinese literature were included in the three major Chinese databases. Since 2011, the number of publications had gradually increased, but in recent years, the number of publications had decreased. The organization with the most publications was the Shenyang Center for Disease Control and Prevention. The cluster analysis of key words mainly formed 9 cluster tags, and the high-frequency keywords mainly included epidemic characteristics, epidemiology, incidence rate, etc. A total of 84 English literature were included in the WOS database, with an overall upward trend in publication volume. The institution with the most publications was the China Center for Disease Control and Prevention, and the most frequently cited journal was “LANCET INFECT DIS”.《Resurgence of scarlet fever in China: a 13-year population-based surveillance study》 was the most cited journal. After keyword cluster analysis, 9 cluster labels were mainly formed, and the keywords were mainly outbreak，Hong Kong, and Group A streptococcus. Conclusion Compared with the English literature, which mainly focuses on spatiotemporal aggregation, etiology and strain resistance, Chinese literature focuses more on epidemic surveillance, clinical features and quality nursing.
ABSTRACT
Objective To explore the effect of different hyperbaric oxygen treatment (HBOT) on delayed neuropsychiatric sequelae followed carbon monoxide (CO) poisoning (DNS).Methods Patients diagnosed acute carbon monoxide poisoning (ACOP) or DNS due to CO poisoning in the hospital from October 2015 to October 2016 were included.Patients who died of ACOP or in persisting unconsciousness condition were excluded.Information of the patients were retrospectively collected including personal data,clinical features and treatment course of hyperbaric oxygen (HBO).All subjects were divided into two groups,consisting of cases who developed into DNS and who fully recovered,according toclinical symptoms.The differences of personal data,clinical features and treatment course of HBO were compared between the two groups.After adjusting the confounding factors,hyperbaric oxygen treatment program of the two groups were analyzed.Results DNS occurred in 39 patients with acute CO poisoning,while 130 patients were fully recovery.The ratio of patients over 55 years old or with smoking history in the DNS group were higher than that in the good outcome group (82.1％ vs.60.8％,23.1％ vs.10.8％).Patients who awoke from unconsciousness but left cognitive impairment were more likely to develop into DNS (P=0.017).Patients who treated with HBO within the first 24 hours,risk of developing into DNS were decreased(OR=0.14,P＜0.01).At the same time,2 times per day and within the first 24 hours worked also as well.(OR=0.29,P=0.011).Even if patients who were given 2 times a day of HBO but not in the first 24 hours after poisoning,could not reduce the risk of evolving to DNS(OR=0.06,P＞0.05);The proportion of patients in the good outcome group accepted HBO for more than six days after poisoning was higher than that in the DNS group (68.5％ vs.48.7％).After adjusting confounding factors,patients who treated with HBO within the first 24 hours (OR=0.22,95％CI:0.09-0.52),2 times per day(OR=0.30,95％CI:0.10-0.87)and lasted for more than 6 days(OR=0.30,95％CI:0.10-0.87)were in a lower risk of involving to DNS.Conclusions For patients diagnosed ACOP,HBOT began in the first 24 hours,1 or 2 times per day or early sustaining to give HBO for more than 6 days could reduce the risk of DNS.
