1Endoscopic ultrasound elastography for evaluation of lymph nodes and pancreatic masses:A multicenter study显示文摘AIM:To evaluate the ability of endoscopic ultrasound(EUS) elastography to distinguish benign from malignant pancreatic masses and lymph nodes.METHODS:A multicenter study was conducted and included 222 patients who underwent EUS examination with assessment of a pancreatic mass(n=121) or lymph node(n=101).The classification as benign or malignant,based on the real time elastography pattern,was compared with the classif ication based on the B-mode EUS images and with the fi nal diagnosis obtained by EUS-guided fi ne needle aspiration(EUS-FNA) and/or by surgical pathology.An interobserver study was performed.RESULTS:The sensitivity and specificity of EUS elastography to differentiate benign from malignant pancreatic lesions are 92.3% and 80.0%,respectively,compared to 92.3% and 68.9%,respectively,for the conventional B-mode images.The sensitivity and specificity of EUS elastography to differentiate benign from malignant lymph nodes was 91.8% and 82.5%,respectively,compared to 78.6% and 50.0%,respectively,for the B-mode images.The kappa coefficient was 0.785 for the pancreatic masses and 0.657 for the lymph nodes.CONCLUSION:EUS elastography is superior compared to conventional B-mode imaging and appears to be able to distinguish benign from malignant pancreatic masses and lymph nodes with a high sensitivity,specificity and accuracy.It might be reserved as a second line examination to help characterise pancreatic masses after negative EUS-FNA and might increase the yield of EUS-FNA for lymph nodes.Marc Giovannini Botelberge Thomas Bories Erwan Pesenti Christian Caillol Fabrice Esterni Benjamin Monges Geneviève Arcidiacono Paolo Deprez Pierre Yeung Robert Schimdt Walter Schrader Hanz Szymanski Carl Dietrich Christoph Eisendrath Pierre Van Laethem Jean-Luc Devière Jacques Vilmann Peter Saftoiu Andrian 2009World Journal of Gastroenterology2009,15,13:48
2Endoscopic ultrasonography guided biliary drainage: Summary of consortium meeting, May 7^(th) , 2011, Chicago显示文摘Endoscopic retrograde cholangiopancreatography (ERCP) has become the preferred procedure for biliary or pancreatic drainage in various pancreatico-biliary disorders. With a success rate of more than 90%, ERCP may not achieve biliary or pancreatic drainage in cases with altered anatomy or with tumors obstructing access to the duodenum. In the past those failures were typically managed exclusively by percutaneous approaches by interventional radiologists or surgical intervention. The morbidity associated was significant especially in those patients with advanced malignancy, seeking minimally invasive interventions and improved quality of life. With the advent of biliary drainage via endoscopic ultrasound (EUS) guidance, EUS guided biliary drainage has been used more frequently within the last decade in different countries. As with any novel advanced endoscopic procedure that encompasses various approaches, advanced endoscopists all over the world have innovated and adopted diverse EUS guided biliary and pancreatic drainage techniques. This diversity has resulted in variations and improvements in EUS Guided biliary and pancreatic drainage; and over the years has led to an extensive nomenclature. The diversity of techniques, nomenclature and recent progress in our intrumentation has led to a dedicated meeting on May 7 th , 2011 during Digestive Disease Week 2011. More than 40 advanced endoscopists from United States, Brazil, Mexico, Venezuela, Colombia, Italy, France, Austria, Germany, Spain, Japan, China, South Korea and India attended this pivotal meeting. The meeting covered improved EUS guided biliary access and drainage procedures, terminology, nomenclature, training and credentialing; as well as emerging devices for EUS guided biliary drainage. This paper summarizes the meeting's agenda and the conclusions generated by the creation of this consortium group.Michel Kahaleh Everson LA Artifon Manuel Perez-Miranda Kapil Gupta Takao Itoi Kenneth F Binmoeller California Pacific Medical Center San Francisco CA 94115 United States Marc Giovannini 2013World Journal of Gastroenterology2013,19,9:15
3Endoscopic resection of superficial gastrointestinal tumors显示文摘Therapeutic endoscopy plays a major role in the management of gastrointestinal (GI) neoplasia. Its indications can be generalized into four broad categories; to remove or obliterate neoplastic lesion, to palliate malignant obstruction, or to treat bleeding. Only endoscopic resection allows complete histological staging of the cancer, which is critical as it allows stratification and refinement for further treatment. Although other endoscopic techniques, such as ablation therapy, may also cure early GI cancer, they can not provide a definitive pathological specimen. Early stage lesions reveal low frequency of lymph node metastasis which allows for less invasive treatments and thereby improving the quality of life when compared to surgery. Endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD) are now accepted worldwide as treatment modalities for early cancers of the GI tract.Giovannini Marc Cesar Vivian Lopes 2008World Journal of Gastroenterology2008,14,29:12

5Kounis syndrome:a clinical entity penetrating from pediatrics to geriatrics显示文摘1 Introduction Kounis syndrome constitutes a coronary hypersensitivity disorder defined by the association of an anaphylactoid,anaphylactic,allergic or hypersensitivity reaction with an acute coronary syndrome,in a physiopathological context involving various interrelated and interacting inflammatory cells,such as mast-cells,eosinophils and platelets.[1,2]Similar entities to Kounis syndrome might involve cerebral and mesenteric arteries.Mattia Giovannini Ioanna Koniari Francesca Mori Silvia Ricci Luciano De Simone Silvia Favilli Sandra Trapani Giuseppe Indolfi Nicholas George Kounis Elio Novembre 2020Journal of Geriatric Cardiology2020,17,5:7
6Endoscopic ultrasonography:Transition towards the futureof gastro-intestinal diseases显示文摘Endoscopic ultrasonography(EUS) is a technique with an established role in the diagnosis and staging of gastro-intestinal tumors. In recent years, the spread of new devices dedicated to tissue sampling has improved the diagnostic accuracy of EUS fine-needle aspiration. The development of EUS-guided drainage of the biliopancreatic region and abdominal fluid collections has allowed EUS to evolve into an interventional tool that can replace more invasive procedures. Emerging techniques applying EUS in pancreatic cancer treatment and in celiac neurolysis have been described. Recently, confocal laser endomicroscopy has been applied to EUS as a promising technique for the in vivo histological diagnosis of gastro-intestinal, bilio-pancreatic and lymph node lesions. In this state-of-the-art review, we report the most recent data from the literature regarding EUS devices, interventional EUS, EUS-guided confocal laser endomicroscopy and EUS pancreatic cancer treatment, and we also provide an overview of their principles, clinical applications and limitations.Stefania De Lisi Marc Giovannini 2016World Journal of Gastroenterology2016,22,5:7
7Endoscopic ultrasonography guided drainage:Summary of consortium meeting,May 21,2012,San Diego,California显示文摘Endoscopic retrograde cholangiopancreatography(ERCP) is the preferred procedure for biliary and pancreatic drainage.While ERCP is successful in about 95% of cases,a small subset of cases are unsuccessful due to altered anatomy,peri-ampullary pathology,or malignant obstruction.Endoscopic ultrasound-guided drainage is a promising technique for biliary,pancreatic and recently gallbladder decompression,which provides multiple advantages over percutaneous or surgical biliary drainage.Multiple retrospective and some prospective studies have shown endoscopic ultrasoundguided drainage to be safe and effective.Based on the currently reported literature,regardless of the approach,the cumulative success rate is 84%-93% with an overall complication rate of 16%-35%.endoscopic ultrasoundguided drainage seems a viable therapeutic modality for failed conventional drainage when performed by highly skilled advanced endoscopists at tertiary centers with expertise in both echo-endoscopy and therapeuticMichel Kahaleh Everson LA Artifon Manuel Perez-Miranda Monica Gaidhane Carlos Rondon Takao Itoi Marc Giovannini 2015World Journal of Gastroenterology2015,21,3:6
8Prediction of genetic value for sweet cherry fruit maturity among environments using a 6K SNP array显示文摘The timing of fruit maturity is an important trait in sweet cherry production and breeding.Phenotypic variation for phenology of fruit maturity in sweet cherry appears to be under strong genetic control,but that control might be complicated by phenotypic instability across environments.Although such genotype-by-environment interaction(G×E)is a common phenomenon in crop plants,knowledge about it is lacking for fruit maturity timing and other sweet cherry traits.In this study,1673 genome-wide SNP markers were used to estimate genomic relationships among 597 weakly pedigree-connected individuals evaluated over two seasons at three locations in Europe and one location in the USA,thus sampling eight‘environments’.The combined dataset enabled a single meta-analysis to investigate the environmental stability of genomic predictions.Linkage disequilibrium among marker loci declined rapidly with physical distance,and ordination of the relationship matrix suggested no strong structure among germplasm.The most parsimonious G×E model allowed heterogeneous genetic variance and pairwise covariances among environments.Narrow-sense genomic heritability was very high(0.60–0.83),as was accuracy of predicted breeding values(>0.62).Average correlation of additive effects among environments was high(0.96)and breeding values were highly correlated across locations.Results indicated that genomic models can be used in cherry to accurately predict date of fruit maturity for untested individuals in new environments.Limited G×E for this trait indicated that phenotypes of individuals will be stable across similar environments.Equivalent analyses for other sweet cherry traits,for which multiple years of data are commonly available among breeders and cultivar testers,would be informative for predicting performance of elite selections and cultivars in new environments.Craig M.Hardner Ben J.Hayes Satish Kumar Stijn Vanderzande Lichun Cai Julia Piaskowski JoséQuero-Garcia JoséAntonio Campoy Teresa Barreneche Daniela Giovannini Alessandro Liverani Gérard Charlot Miguel Villamil-Castro Nnadozie Oraguzie Cameron P.Peace 2019Horticulture Research2019,6,1:5

12Cardiovascular disease risk factor profiles in children with celiac disease on gluten-free diets显示文摘AIM:To describe the cardiovascular disease(CVD)risk factors in a population of children with celiac disease(CD)on a gluten-free diet(GFD).METHODS:This cross-sectional multicenter study was performed at Schneider Children’s Medical Center of Israel(Petach Tiqva,Israel),and San Paolo Hospital(Milan,Italy).We enrolled 114 CD children in serologic remission,who were on a GFD for at least one year.At enrollment,anthropometric measurements,blood lipids and glucose were assessed,and compared to values at diagnosis.The homeostasis model assessment-estimated insulin resistance was calculated as a measure of insulin resistance.RESULTS:Three or more concomitant CVD risk factors[body mass index,waist circumference,low density lipoprotein(LDL)cholesterol,triglycerides,blood pressure and insulin resistance]were identified in 14%of CD subjects on a GFD.The most common CVD risk factors were high fasting triglycerides(34.8%),elevated blood pressure(29.4%),and high concentrations of calculated LDL cholesterol(24.1%).On a GFD,four children(3.5%)had insulin resistance.Fasting insulin and HOMA-IR were significantly higher in the Italian cohort compared to the Israeli cohort(P<0.001).Children on a GFD had an increased prevalence of borderline LDL cholesterol(24%)when compared to values(10%)at diagnosis(P=0.090).Trends towards increases in overweight(from 8.8%to 11.5%)and obesity(from 5.3%to 8.8%)were seen on a GFD.CONCLUSION:This report of insulin resistance and CVD risk factors in celiac children highlights the importance of CVD screening,and the need for dietary counseling targeting CVD prevention.Lorenzo Norsa Raanan Shamir Noam Zevit Elvira Verduci Corina Hartman Diana Ghisleni Enrica Riva Marcello Giovannini 2013World Journal of Gastroenterology2013,19,34:3
13AMPA受体及其拮抗剂在癫痫持续状态中的作用显示文摘癫痫持续状态(Status epilepticus,SE)通常定义为长时间持续的癫痫发作或反复发作且发作间期未完全恢复。SE是一种急症,通常与严重的残疾、较高的发病率和死亡率相关。尽管受临床的影响,但从自限性癫痫发作过渡到持续的、难治性的癫痫发作的潜在机制仍尚不完全明确。在SE中,约40%的患者对抗癫痫药物(AEDs)(一线治疗)无效;因此,需要更有效的药物。在这篇综述中,我们着重于目前对于α-氨基-3-羟基-5-羟基-5-甲基-4-异恶唑丙酸(alpha-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid,AMPA)受体在SE中作用的了解,以及其拮抗剂的临床前功效和当前发表的涉及具有这种作用机制的药物的临床研究。我们对关于AMPA受体、AMPA受体拮抗剂和SE的实验性和临床研究文章进行了全面的文献检索。近年来,AMPA受体在SE发作期间和发作后的作用变得逐渐清晰,现在已被广泛接受的是其早期变化发生在初始阶段,这可能有导致SE的维持及其对治疗的抵抗性。AMPA受体拮抗剂已在几种SE动物模型中被证实可终止发作,这些研究支持着抑制AMPA受体的治疗潜力。迄今为止,人体研究的相关数据很有限,但前景广阔,它们支持在SE患者中使用AMPA受体拮抗剂。当二线药物首次尝试失败后,AMPA受体拮抗剂可能成为确定的SE患者的新治疗选择,特别是在苯二氮卓作为二线治疗失败后,甚至效果可能更好。Antonio Leo Giada Giovannini Emilio Russo 张乐(译) 熊维希(审) 慕洁(审) 2020癫痫杂志2020,6,2:3
14Combined Experimental and Numerical Investigations on the Roughness Effects on the Aerodynamic Performances of LPT Blades显示文摘The aerodynamic performance of a high-load low-pressure turbine blade cascade has been analyzed for three different distributed surface roughness levels(Ra) for steady and unsteady inflows. Results from CFD simulations and experiments are presented for two different Reynolds numbers(300000 and 70000 representative of take-off and cruise conditions, respectively) in order to evaluate the roughness effects for two typical operating conditions. Computational fluid dynamics has been used to support and interpret experimental results, analyzing in detail the flow field on the blade surface and evaluating the non-dimensional local roughness parameters, further contributing to understand how and where roughness have some influence on the aerodynamic performance of the blade. The total pressure distributions in the wake region have been measured by means of a five-hole miniaturized pressure probe for the different flow conditions, allowing the evaluation of profile losses and of their dependence on the surface finish, as well as a direct comparison with the simulations. Results reported in the paper clearly highlight that only at the highest Reynolds number tested(Re=300000) surface roughness have some influence on the blade performance, both for steady and unsteady incoming flows. In this flow condition profile losses grow as the surface roughness increases, while no appreciable variations have been found at the lowest Reynolds number. The boundary layer evolution and the wake structure have shown that this trend is due to a thickening of the suction side boundary layer associated to an anticipation of transition process. On the other side, no effects have been observed on the pressure side boundary layer.Marco Berrino Fabio Bigoni Daniele Simoni Matteo Giovannini Michele Marconcini Roberto Pacciani Francesco Bertini 2016Journal of Thermal Science2016,25,1:3
