| 1 | Development and internal validation of the Comprehensive ALPPS Preoperative Risk Assessment(CAPRA)score:is the patient suitable for Associating Liver Partition and Portal vein ligation for Staged hepatectomy(ALPPS)?显示文摘Background:Preoperative patient selection in Associating Liver Partition and Portal vein ligation for Staged hepatectomy(ALPPS)is not always reliable with currently available scores,particularly in patients with primary liver tumor.This study aims to(I)to determine whether comorbidities and patients characteristics are a risk factor in ALPPS and(II)to create a score predicting 90-day mortality preoperatively.Methods:Thirteen high-volume centers participated in this retrospective multicentric study.A risk analysis based on patient characteristics,underlying disease and procedure type was performed to identify risk factors and model the Comprehensive ALPPS Preoperative Risk Assessment(CAPRA)score.A nonparametric receiver operating characteristic analysis was performed to estimate the predictive ability of our score against the Charlson Comorbidity Index(CCI),the age-adjusted CCI(aCCI),the ALPPS risk score before Stage 1(ALPPS-RS1)and Stage 2(ALPPS-RS2).The model was internally validated applying bootstrapping.Results:A total of 451 patients were included.Mortality was 14.4%.The CAPRA score is calculated based on the following formula:(0.1×age)−(2×BSA)+1(in the presence of primary liver tumor)+1(in the presence of severe cardiovascular disease)+2(in the presence of moderate or severe diabetes)+2(in the presence of renal disease)+2(if classic ALPPS is planned).The predictive ability was 0.837 for the CAPRA score,0.443 for CCI,0.519 for aCCI,0.693 for ALPPS-RS1 and 0.807 for ALPPS-RS2.After 1,000 cycles of bootstrapping the C statistic was 0.793.The accuracy plot revealed a cut-off for optimal prediction of postoperative mortality of 4.70.Conclusions:Comorbidities play an important role in ALPPS and should be carefully considered when planning the procedure.By assessing the patient’s preoperative condition in relation to ALPPS,the CAPRA score has a very good ability to predict postoperative mortality. | Ivan Capobianco Karl J.Oldhafer Mohammed-Hossein Fard-Aghaie Ricardo Robles-Campos Roberto Brusadin Henrik Petrowsky Michael Linecker Arianeb Mehrabi Katrin Hoffmann Jun Li Asmus Heumann Roberto Hernandez-Alejandro Mauro Enrique Tun-Abraham Elio Jovine Matteo Serenari Bergthor Bjornsson Per Sandström Ruslan Alikhanov Mikhail Efanov Paolo Muiesan Andrea Schlegel Thomas M.van Gulik Pim B.Olthof Gregor Alexander Stavrou Lina Maria Serna-Higuita Alfred Königsrainer Silvio Nadalin | 2022 | Hepatobiliary Surgery and Nutrition2022，11，1： | 1 |
| 2 | Osteopontin targeted theranostic nanoprobes for laser-induced synergistic regression of vulnerable atherosclerotic plaques显示文摘Vulnerable atherosclerotic plaque(VASPs)is the major pathological cause of acute cardiovascular event.Early detection and precise intervention of VASP hold great clinical significance,yet remain a major challenge.Photodynamic therapy(PDT)realizes potent ablation efficacy under precise manipulation of laser irradiation.In this study,we constructed theranostic nanoprobes(NPs),which could precisely regress VASPs through a cascade of synergistic events triggered by local irradiation of lasers under the guidance of fluorescence/MR imaging.The NPs were formulated from human serum albumin(HSA)conjugated with a high affinity-peptide targeting osteopontin(OPN)and encapsulated with photosensitizer IR780 and hypoxia-activatable tirapazamine(TPZ).After intravenous injection into atherosclerotic mice,the OPN-targeted NPs demonstrated high specific accumulation in VASPs due to the overexpression of OPN in activated foamy macrophages in the carotid artery.Under the visible guidance of fluorescence and MR dual-model imaging,the precise near-infrared(NIR)laser irradiation generated massive reactive oxygen species(ROS),which resulted in efficient plaque ablation and amplified hypoxia within VASPs.In response to the elevated hypoxia,the initially inactive TPZ was successively boosted to present potent biological suppression of foamy macrophages.After therapeutic administration of the NPs for 2 weeks,the plaque area and the degree of carotid artery stenosis were markedly reduced.Furthermore,the formulated NPs displayed excellent biocompatibility.In conclusion,the developed HSA-based NPs demonstrated appreciable specific identification ability of VASPs and realized precise synergistic regression of atherosclerosis. | Mengqi Xu Cong Mao Haoting Chen Lu Liu Yabin Wang Abid Hussain Sulei Li Xu Zhang Ruslan G.Tuguntaev Xing-Jie Liang Weisheng Guo Feng Cao | 2022 | Acta Pharmaceutica Sinica B2022，12，4： | 0 |
