RESULTS CLN-EBV concentrations ≥ 787.5 copies/ml were regarded as positive according to receiver-operating characteristic curve analysis. The AUC of the EBV (0.925) concentration in CLN metastasis was significantly larger than the AUC of MRI (0.714) (P  0.05) and 84.62% (P  less then  0.01) for EBV DNA in CLN metastasis, respectively. The sensitivity and specificity of EBV in plasma were 77.2% and 71.8%, respectively. The diagnostic specificity and AUC of EBV in CLNs were higher than those of MRI and plasma EBV (P  less then  0.005). CONCLUSIONS Ultrasound-guided CLN FNA to obtain EBV concentrations may provide a new method to diagnose CLN metastasis with high sensitivity and specificity.BACKGROUND An early diagnosis of acute coronary syndrome (ACS) is crucial for treatment and prognosis. The aim of this study was to evaluate the Manchester triage system (MTS) for patients with ACS, e.g. ST-segment elevation myocardial infarction (STEMI), non-ST elevation myocardial infarction (N-STEMI) and unstable angina pectoris (UAP). METHODS Retrospective analysis of patients diagnosed with ACS (STEMI, N‑STEMI and UAP) who were triaged in the emergency department (ED) with the MTS. RESULTS In this study 282 patients with ACS (STEMI 34.0%, N‑STEMI 61.7%, UAP 4.3%) were triaged as MTS level 1 (immediate assessment) 0.4%, MTS level 2 (very urgent) 51.4%, MTS level 3 (urgent) 41.5%, MTS level 4 (standard) 6.7%, MTS level 5 (non-urgent) 0%. We observed significantly lower mean MTS levels in males (male 2.48 ± 0.59, female 2.68 ± 0.68, p = 0.02) and in patients younger than 80 years (age less then 80 years 2.50 ± 0.61, age ≥80 years 2.70 ± 0.67, p = 0.03). We did not find a significant difference of mean MTS levels in different types of ACS (STEMI 2.46 ± 0.6, N‑STEMI 2.59 ± 0.64, STEMI vs N‑STEMI p = 0.11, UAP 2.67 ± 0.65, STEMI vs UAP p = 0.26) and with respect to d
