Here we aim to verify this model in a large cohort of patients.METHODS: A total of 2727 patients undergoing LT with endstage liver cirrhosis from January 2003 to December 2010 were included in this retrospective study. Data were collected from the China Liver Transplant Registry(CLTR). PMPM score was calculated at 24-h and 7-d following LT. According to the PMPM score at 24-h, all patients were divided into the low-risk group(PMPM score ≤-1.4, n=2509) and the high-risk group(PMPM score 〉-1.4, n=218). The area under receiver operator characteristic curve(AUROC) was calculated for evaluating the prognostic accuracy.RESULTS: The 1-, 3-, and 5-year patient survival rates in the low-risk group were significantly higher than those in the high-risk group(90.23%, 88.01%, and 86.03% vs 63.16%, 59.62%, and 56.43%, respectively, P〈0.001). In the high-risk group, 131 patients had a decreased PMPM score(≤-1.4) at 7-d, and their cumulative survival rate was significantly higher than the other 87 patients with sustained high PMPM score(〉-1.4)(P〈0.001). For predicting 3-month mortality, PMPM score showed a much higher AUROC than post-transplant MELD score(P〈0.05).CONCLUSION: PMPM score is a simple and effective tool to predict short-term mortality after liver transplantation in patients with benign liver diseases, and an indicator for prompt salvaging treatment as well.展开更多

文摘Background Monocyte to high density lipoprotein ratio(MHR) has been considered as a novel parameter related with adverse renal and cardiovascular outcomes.In this study we investigated the association of MHR with major adverse clinical events(MACEs) in patients with type 2 diabetes mellitus(T2DM) undergoing elective percutaneous coronary intervention(PCI).Methods Consecutive T2 DM patients treated with elective PCI were prospectively recruited between July 2008-January 2016 in Department of Cardiology of Panyu Central Hospital.Subjects were categorized into two groups:as patients who developed MACEs(MACEs+) and patients who did not develop MACEs(MACEs-) during hospitalization.MACEs were defined as the composite end points,including all-cause mortality,or acute heart failure,or target vessel revascularization,or stroke or recurrent angina.Results A total of 418 patients were included in the study.64 patients developed MACEs(15.3%).In the MACEs(+) patients,monocytes were higher(1.12 [0.78-1.42] vs.0.72 [0.68-0.92] 109/L,P 〈 0.01) and HDL cholesterol levels were lower(0.87 [0.72-1.21] vs.0.96 [0.81-1.11] mmol/L,P 〈 0.01).In addition,MHR was significantly higher in the MACEs(+) group(1.12 [0.91-2.09] vs.0.73[0.54-0.93] 109 mmol/L,P 〈 0.01).The cutoff value of MHR for predicting MACEs was 22,with a sensitivity of 81% and a specificity of 75.1%(area under the curve0.79,P 〈 0.001).In multivariate logistic regression analysis,MHR remained an independent factor correlated with MACEs(OR = 3.97,95%CI = 1.38-11.5,P 〈 0.01).Conclusion Higher MHR levels may predict MACEsdevelopment after elective PCI in T2 DM patients.
