| 1 | Evaluation of Doppler-ultrasonography in the diagnosis of transjugular intrahepatic portosystemic shunt dysfunction: A prospective study显示文摘AIM To prospectively evaluate the performance of Dopplerultrasonography(US) for the detection of transjugular intrahepatic portosystemic shunt(TIPS) dysfunction within a multicenter cohort of cirrhotic patients.METHODS This study was conducted in 10 french teaching hospitals. After TIPS insertion, angiography and liver Doppler-US were carried out every six months to detect dysfunction(defined by a portosystemic gradient ≥ 12 mm Hg and/or a stent stenosis ≥ 50%). The association between ultrasonographic signs and dysfunction was studied by logistic random-effects models, and the diagnostic performance of each Doppler criterion was estimated by the bootstrap method. This study was approved by the ethics committee of Tours.RESULTS Two hundred and eighteen pairs of examinations performed on 87 cirrhotic patients were analyzed. Variables significantly associated with dysfunction were: The speed of flow in the portal vein(P = 0.008), the reversal of flow in the right(P = 0.038) and left(P = 0.049) portal branch, the loss of modulation of portal flow by the right atrium(P = 0.0005), ascites(P = 0.001) and the overall impression of the operator(P = 0.0001). The diagnostic performances of these variables were low; sensitivity was < 58% and negative predictive value was < 73%. Therefore, dysfunction cannot be ruled out from Doppler-US. CONCLUSION The performance of Doppler-US for the detection of TIPS dysfunction is poor compared to angiography. New tools are needed to improve diagnosis of TIPS dysfunction. | Charlotte Nicolas Amelie Le Gouge Louis d’Alteroche Jean Ayoub Monica Georgescu Vincent Vidal Denis Castaing Jean-Pierre Cercueil Patrick Chevallier Jerome Roumy Herve Trillaud Louis Boyer Vincent Le Pennec Christophe Perret Bruno Giraudeau Jean-Marc Perarnau STIC-TIPS group | 2017 | World Journal of Hepatology2017，9，27： | 6 |
| 2 | 全科医学科研的范畴、研究需求和适用方法——《欧洲全科医学/家庭医学和基本医疗保健科研纲要》中文摘译显示文摘本文对《欧洲全科医学/家庭医学和基本医疗保健科研纲要》的中文译稿进行了重点摘登。该文件由欧洲全科医学科研网络制订,包括7部分内容:序言、导言、方法、结果、独立章节,讨论和启示。作为在欧洲发展全科医学科研的核心指南,该文件对欧洲的全科医学学科和科研发展产生了深远的影响。欧洲的全科医学体系和以此为基础而构建的学科理论共识与我国全科医学当前的实际情况可能更为接近。因篇幅所限,本文刊登了其中最重要,对中国研究者也最实用的5部分内容,包括:(1)导言——全科医学的核心能力/特征以及全科医学科研的意义;(2)结果——全科医学的6个核心领域(基本保健管理、'以人为本'的照护、解决具体问题的技能、综合的方法、以社区为导向、整体的方法)的科研范畴,研究需求和适用方法;(3)独立章节——如何发展基本的科研能力和避免常见的科研失误;(4)讨论——未来的全科医学科研重点;(5)启示——科学协会、研究机构、患者参与、科研工作、期刊、科研政策在发展学科方面应注重的问题。因欧洲的全科医学体制和我国较为相似,且存在一定的科研发展代差,该文件在当前阶段也可为我国全科医学研究者所用,基于全科医学学科的视角,从概念、分类学、范围和科研方法等方面,为我国全科医学科研的发展提供参照。 | Eva Hummers-Pradier Martin Beyer Patrick Chevallier Sophia Eilat-Tsanani Christos Lionis Lieve Peremans Davorina Petek Imre Rurik Jean Karl Soler Henri E.J.H.Stoffers Pinar Topsever Mehmet Ungan Paul van Royen Hanny Prick 无 | 2022 | 中国全科医学2022，25，9： | 4 |

| 8 | Expected outcomes and patients’selection before chemoembolization—“Six-and-Twelve or Pre-TACE-Predict”scores may help clinicians:Real-life French cohorts results显示文摘BACKGROUND Careful selection of hepatocellular carcinoma(HCC)patients prior to chemoembolization treatment is a daily reality,and is even more necessary with new available therapeutic options in HCC.To propose two new models to better stratify patients and maximize clinical benefit:“6 and 12”and“pre/post-TACE-predict”(TACE,transarterial chemoembolization).METHODS We evaluated and compared their performance in predicting overall survival with other systems{Barcelona Clinic Liver Cancer(BCLC),Albumin-Bilirubin(ALBI)and NIACE[Number of tumor(s),Infiltrative HCC,alpha-fetoprotein,Child-Pugh(CP),and performance status]}in two HCC French cohorts of different stages enrolled between 2010 and 2018.RESULTS The cohorts included 324 patients classified as BCLC stages A/B(cohort 1)and 137 patients classified as BCLC stages B/C(cohort 2).The majority of the patients had cirrhosis with preserved liver function.“Pre-TACE-predict”and“6 and 12”models identified three distinct categories of patients exhibiting different prognosis in cohort 1.However,their prognostic value was no better than the BCLC system or NIACE score.Liver function based on CP and ALBI grades significantly impacted patient survival.Conversely,the“post-TACE-predict”model had a higher predictive value than other models.The stratification ability as well as predictive performance of these new models in an intermediate/advanced stage population was less efficient(cohort 2).CONCLUSION The newly proposed“Pre-TACE-predict”and“6 and 12”models offer an interesting stratification into three categories in a recommended TACE population,as they identify poor candidates,those with partial control and durable response.The models'contribution was reduced in a population with advanced stage HCCs. | Xavier Adhoute Edouard Larrey Rodolphe Anty Patrick Chevallier Guillaume Penaranda Albert Tran Jean-Pierre Bronowicki Jean-Luc Raoul Paul Castellani HervéPerrier Olivier Bayle Olivier Monnet Bernard Pol Marc Bourliere | 2021 | World Journal of Clinical Cases2021，9，18： | 0 |
