BACKGROUND:This study aimed to evaluate the discriminatory performance of 11 vital sign-based early warning scores(EWSs)and three shock indices in early sepsis prediction in the emergency department(ED).METHODS:We performed a retrospective study on consecutive adult patients with an infection over 3 months in a public ED in Hong *** primary outcome was sepsis(Sepsis-3 definition)within 48 h of ED *** c-statistics and the DeLong test,we compared 11 EWSs,including the National Early Warning Score 2(NEWS2),Modified Early Warning Score,and Worthing Physiological Scoring System(WPS),etc.,and three shock indices(the shock index[SI],modified shock index[MSI],and diastolic shock index[DSI]),with Systemic Inflammatory Response Syndrome(SIRS)and quick Sequential Organ Failure Assessment(qSOFA)in predicting the primary outcome,intensive care unit admission,and mortality at different time ***:We analyzed 601 patients,of whom 166(27.6%)developed ***2 had the highest point estimate(area under the receiver operating characteristic curve[AUROC]0.75,95%CI 0.70-0.79)and was significantly better than SIRS,qSOFA,other EWSs and shock indices,except WPS,at predicting the primary ***,the pooled sensitivity and specificity of NEWS2≥5 for the prediction of sepsis were 0.45(95%CI 0.37-0.52)and 0.88(95%CI 0.85-0.91),*** discriminatory performance of all EWSs and shock indices declined when used to predict mortality at a more remote time ***:NEWS2 compared favorably with other EWSs and shock indices in early sepsis prediction but its low sensitivity at the usual cut-off point requires further modification for sepsis screening.

To the Editor : Barcelona Clinic Liver Cancer(BCLC) Stage C hepatocellular carcinoma(HCC) with vascular invasion has been considered unresectable. However, the curative rate from systemic treatment is rather dismal. Even with the use of immunotherapy, complete remission is less than 10% [ 1 ]. On the contrary, recent advances in transplant oncology, especially in the application of liver transplant-related surgical techniques in complex liver resections, make the operation possible for patients with locally advanced HCC who were previously considered to be unresectable [ 2 ]. We hereby present the surgical management of a patient with giant HCC in right liver lobe with inferior vena cava(IVC) invasion.
