ABSTRACT
Objective:To explore the diagnostic value of Caprini score for acute pulmonary embolism(APE).Methods:Totally 2 764 patients with suspected APE admitted to Yuncheng Central Hospital were enrolled from January 2012 to January 2019, and 312 patients were diagnosed APE and assigned to APE group finally.Among the patients without APE, 312 patients(control group) were matched with the patients in APE group according to age, gender, weight, blood pressure, surgical history, etc.The general clinical data of the two groups were collected, and the Caprini score of each patient was recorded.The differences between the two groups in clinical data and Caprini score were compared.The area under curves(AUC) of receiver operating characteristic(ROC) was calculated to predict the diagnostic efficacy of Caprini scale for patients with APE.Results:The Caprini score of the APE group was significantly higher than that of the control group[(5.41±2.47)points vs.(2.16±1.28)points, t=1.180, P=0.004]. The Caprini score had a favorable diagnostic efficacy for patients with suspected APE(AUC=0.915, 95% CI: 0.878-0.995, P<0.001), and when the 3.5 cutoff value of Caprini score was determined, the specificity and sensitivity were 87.76% and 95.24%, respectively, with 7.778 of positive likelihood ratio, 0.054 of negative likelihood ratio, and 0.83 of Youden index. Conclusion:Caprini score has strong diagnostic efficacy in patients with APE.
ABSTRACT
Objective@#To evaluate the epidemiologic characteristics of hand, foot and mouth disease in Zhejiang province between 2009 and 2017, so that scientific evidence could be provided for prevention and control of hand, foot and mouth disease.@*Methods@#Spatial, temporal and population distribution of HFMD was analyzed. Real-time reverse transcription polymerase cain reaction was used to test Enterovirus A71 and Coxsackievirus A16 in samples.@*Results@#Between 2009 and 2017, 1 108 093 HFMD cases were reported in Zhejiang with the prevalence of 226.24/100000; 2010, 2012, 2014 and 2016 had a higher prevalence than other years. Prevalence of HFMD peaked in April-July and September-October. Wenzhou, Taizhou and Ningbo had a higher prevalence than other cities. In total, 69.27% cases were children who were not enrolled in nursery school, and 65.67% were 1-3 years old. Pathogen surveillance showed that EV-A71 decreased in mild cases, whereas other enterovirus increased. However EV-A71 was still predominant in severe and fatal cases (56.0%).@*Conclusions@#Temporal and spatial distribution of HFMD is characteristic in Zhejiang province. EV-A71 predominated in severe cases and fatal cases, while other enterovirus (non-EV-A71, non CV-A16) were the main pathogen for mild cases.
