1欧洲儿童急性胃肠炎处理循证指南(2014年版)显示文摘1991年世界卫生组织(WHO)制订了第一版儿童急性腹泻病指南,2005年WHO和联合国儿童基金会(UNICEF)制订了第二版,我国专家在参照WHO指南的基础上,结合我国国情分别于1993年、2009年制订了中国儿童急性腹泻病的专家共识;WH0指南和我国共识对中国儿童急性腹泻病的规范诊治发挥了重要的作用,收到了良好的效果。时至今日,欧洲儿科胃肠病学、肝病学和营养协会及欧洲儿科感染病协会对2008年儿童急性胃肠炎循证指南进行更新,即“2014年版”。指南中腹泻病原、低渗口服补液盐溶液使用、营养管理和常规对症治疗与我国现行共识基本一致。另首次对儿童脱水评估和疾病严重程度评分进行量化并提出通过鼻胃管补液,这是我们可以借鉴的。重度脱水休克的治疗强调了可重复3次20ml/kg0.9%氯化钠溶液,与我国危重专业观点相一致。静脉补充液体成分与我国现行共识存在差异,与指南执笔者之一意大利学者AndreaLoVecehio进行交流,其认同我国现用液体组成。细菌感染所致腹泻使用抗生素的指征与我国现行共识相同,但在抗生素选择上存在差异,建议根据我国药典和药敏结果选择合适抗生素。由于我国社会经济、文化和医学发展等与欧洲存在差异,因此指南中的观点、方法等应结合中国特点进行应用。Alfredo Guarino Shai Ashkenazi Dominique Gendrel Andrea Lo Vecchio Raanan Shamir Hania Szajewska 方铁夫 耿岚岚 龚四堂 2015中华儿科杂志2015,53,7:30
2high-entropy silicide:(Mo_(0.2)Nb_(0.2)Ta_(0.2)Ti_(0.2)W_(0.2))Si_(2)显示文摘A high-entropy metal disilicide,(Mo_(0.2)Nb_(0.2)Ta_(0.2)Ti_(0.2)W_(0.2))Si_(2),has been successfully synthesized.X-ray diffraction(XRD),energy dispersive X-ray spectroscopy(EDX),and electron backscatter diffraction(EBSD)collectively show the formation of a single high-entropy silicide phase.This high-entropy(Mo_(0.2)Nb_(0.2)Ta_(0.2)Ti_(0.2)W_(0.2))Si_(2) possesses a hexagonal C40 crystal structure with ABC stacking sequence and a space group of P6222.This discovery expands the known families of high-entropy materials from metals,oxides,borides,carbides,and nitrides to a silicide,for the first time to our knowledge,as well as demonstrating that a new,non-cubic,crystal structure(with lower symmetry)can be made into highentropy phase.This(Mo_(0.2)Nb_(0.2)Ta_(0.2)Ti_(0.2)W_(0.2))Si_(2) exhibits high nanohardness of 16.7±1.9 GPa and Vickers hardness of 11.6±0.5 GPa.Moreover,it has a low thermal conductivity of 6.9±1.1Wm^(-1) K^(-1),which is approximately one order of magnitude lower than that of the widely-used tetragonal MoSi_(2) and ~1/3 of those reported values for the hexagonal NbSi_(2) and TaSi_(2) with the same crystal structure.Joshua Gild Jeffrey Braun Kevin Kaufmann Eduardo Marin Tyler Harrington Patrick Hopkins Kenneth Vecchio Jian Luo 2019Journal of Materiomics2019,5,3:27
3Coronary thrombus in patients undergoing primary PCI for STEMI:Prognostic significance and management显示文摘Acute ST-elevation myocardial infarction(STEMI) usually results from coronary atherosclerotic plaque disruption with superimposed thrombus formation. Detection of coronary thrombi is a poor prognostic indicator,which is mostly proportional to their size and composition. Particularly,intracoronary thrombi impair both epicardial blood flow and myocardial perfusion,by occluding major coronary arteries and causing distal embolization,respectively. Thus,although primary percutaneous coronary intervention is the preferred treatement strategy in STEMI setting,the associated use of adjunctive antithrombotic drugs and/or percutaneous thrombectomy is crucial to optimize therapy of STEMI patients,by improving either angiographical and clinical outcomes. This review article will focus on the prognostic significance of intracoronary thrombi and on current antithrombotic pharmacological and interventional strategies used inthe setting of STEMI to manage thrombotic lesions.Sabine Vecchio Elisabetta Varani Tania Chechi Marco Balducelli Giuseppe Vecchi Matteo Aquilina Giulia Ricci Lucchi Alessro Dal Monte Massimo Margheri 2014World Journal of Cardiology2014,6,6:18
4Developmental pathways associated with cancer metastasis:Notch,Wnt,and Hedgehog显示文摘Master developmental pathways, such as Notch, Wnt, and Hedgehog, are signaling systems that control proliferation, cell death,motility, migration, and stemness. These systems are not only commonly activated in many solid tumors, where they drive or contribute to cancer initiation, but also in primary and metastatic tumor development. The reactivation of developmental pathways in cancer stroma favors the development of cancer stem cells and allows their maintenance, indicating these signaling pathways as particularly attractive targets for efficient anticancer therapies, especially in advanced primary tumors and metastatic cancers. Metastasis is the worst feature of cancer development. This feature results from a cascade of events emerging from the hijacking of epithelial-mesenchymal transition, angiogenesis, migration, and invasion by transforming cells and is associated with poor survival, drug resistance, and tumor relapse. In the present review, we summarize and discuss experimental data suggesting pivotal roles for developmental pathways in cancer development and metastasis, considering the therapeutic potential. Emerging targeted antimetastatic therapies based on Notch, Wnt, and Hedgehog pathways are also discussed.Armel Herve Nwabo Kamdje Paul Takam Kamga Richard Tagne Simo Lorella Vecchio Paul Faustin Seke Etet Jean Marc Muller Giulio Bassi Erique Lukong Raghuveera Kumar Goel Jeremie Mbo Amvene Mauro Krampera 2017Cancer Biology & Medicine2017,14,2:10
5Impairment of ghrelin synthesis in Helicobacter pyloricolonized stomach:New clues for the pathogenesis of H.pylori-related gastric inflammation显示文摘Ghrelin,the ligand of growth hormone secretagogue receptor 1a,takes part in several functions of the digestive system,including regulation of appetite,energy homeostasis,gastric acid secretion and motility.Ghrelin has also immunoregulatory properties and is supposed to inhibit some inflammatory pathways that can mediate gastric damage.Interestingly,ghrelin synthesis is reduced in the gastric mucosa of patients with Helicobacter pylori(H.pylori)infection,a worldwide condition inducing a T helper(Th)1/Th17 cell responsedriven gastritis,which may evolve towards gastric atrophy and cancer.In this article,we review the available data on the expression of ghrelin in H.pylori infection and discuss how the defective ghrelin synthesis may contribute to sustain the ongoing inflammatory response in this disease.Omero Alessandro Paoluzi Giovanna Del Vecchio Blanco Roberta Caruso Ivan Monteleone Giovanni Monteleone Francesco Pallone 2014World Journal of Gastroenterology2014,20,3:8
6Treatment of peri-anal fistula in Crohn's disease显示文摘Anal fistulas are a common manifestation of Crohn's disease(CD). The first manifestation of the disease is often in the peri-anal region, which can occur years before a diagnosis, particularly in CD affecting the colon and rectum. The treatment of peri-anal fistulas is difficult and always multidisciplinary. The European guidelines recommend combined surgical and medical treatment with biologic drugs to achieve best results. Several different surgical techniques are currently em-ployed. However, at the moment, none of these tech-niques appear superior to the others in terms of healing rate. Surgery is always indicated to treat symptomatic, simple, low intersphincteric fistulas refractory to medi-cal therapy and those causing disabling symptoms. Ut-most attention should be paid to correcting the balance between eradication of the fistula and the preservationof fecal continence.Giuseppe S Sica Sara Di Carlo Giorgia Tema Fabrizio Montagnese Giovanna Del Vecchio Blanco Valeria Fiaschetti Giulia Maggi Livia Biancone 2014World Journal of Gastroenterology2014,20,37:8
7Malignant gastric outlet obstruction:Which is the best therapeutic option?显示文摘Malignant gastric outlet obstruction(MGOO)is a clinical condition characterized by the mechanical obstruction of the pylorus or the duodenum due to tumor compression/infiltration,with consequent reduction or impossibility of an adequate oral intake.MGOO is mainly secondary to advanced pancreatic or gastric cancers,and significantly impacts on patients’survival and quality of life.Patients suffering from this condition often present with intractable vomiting and severe malnutrition,which further compromise therapeutic chances.Currently,palliative strategies are based primarily on surgical gastrojejunostomy and endoscopic enteral stenting with self-expanding metal stents.Several studies have shown that surgical approach has the advantage of a more durable relief of symptoms and the need of fewer re-interventions,at the cost of higher procedure-related risks and longer hospital stay.On the other hand,enteral stenting provides rapid clinical improvement,but have the limit of higher stent dysfunction rate due to tumor ingrowth and a subsequent need of frequent reinterventions.Recently,a third way has come from interventional endoscopic ultrasound,through the development of endoscopic ultrasound-guided gastroenterostomy technique with lumen-apposing metal stent.This new technique may ideally encompass the minimal invasiveness of an endoscopic procedure and the long-lasting effect of the surgical gastrojejunostomy,and brought encouraging results so far,even if prospective comparative trial are still lacking.In this Review,we described technical aspects and clinical outcomes of the above-cited therapeutic approaches,and discussed the open questions about the current management of MGOO.Edoardo Troncone Alessandro Fugazza Annalisa Cappello Giovanna Del Vecchio Blanco Giovanni Monteleone Alessandro Repici Anthony Yuen Bun Teoh Andrea Anderloni 2020World Journal of Gastroenterology2020,26,16:7
8Low efficacy of levofloxacin-doxycycline-based third-line triple therapy for Helicobacter pylori eradication in Italy显示文摘AIM:To evaluate a levofloxacin-doxycycline-based triple therapy with or without a susceptibility culture test in non-responders to Helicobacter pylori(H.pylori) eradication.METHODS:A total of 142(99 women,43 men; mean 53.0 ± 12.7 years) non-responders to more than two H.pylori eradication therapies underwent susceptibility culture tests or were treated with a seven-day triple therapy consisting of esomeprazole,20 mg b.i.d.,levofloxacin,500 mg b.i.d.,and doxycycline,100 mg b.i.d.,randomly associated with(n = 71) or without(n = 71) Lactobacillus casei DG.H.pylori status was checked in all patients at enrollment and at least 8 wk after the end of therapy.Compliance and tolerability of regimens were also assessed.RESULTS:H.pylori eradication was achieved in < 50% of patients [per prototol(PP) = 49%; intention to treat(ITT) = 46%].Eradication rate was higher in patients administered probiotics than in those without(PP = 55% vs 43%; ITT = 54% vs 40%).Estimated primary resistance to levofloxacin was 18% and multiple resistance was 31%.Therapy was well tolerated,and side effects were generally mild,with only one patient experiencing severe effects.CONCLUSION:Third-line levofloxacin-doxycycline triple therapy had a low H.pylori eradication efficacy,though the success and tolerability of this treatment may be enhanced with probiotics.Omero Alessandro Paoluzi Giovanna Del Vecchio Blanco Emanuela Visconti Manuela Coppola Carla Fontana Marco Favaro Francesco Pallone 2015World Journal of Gastroenterology2015,21,21:5
9Mesenchymal stromal cells' role in tumor microenvironment:involvement of signaling pathways显示文摘Mesenchymal stromal cells(MSCs) are adult multipotent stem cells residing as pericytes in various tissues and organs where they can differentiate into specialized cells to replace dying cells and damaged tissues. These cells are commonly found at injury sites and in tumors that are known to behave like 'wounds that do not heal.' In this article, we discuss the mechanisms of MSCs in migrating, homing, and repairing injured tissues. We also review a number of reports showing that tumor microenvironment triggers plasticity mechanisms in MSCs to induce malignant neoplastic tissue formation, maintenance, and chemoresistance, as well as tumor growth. The antitumor properties and therapeutic potential of MSCs are also discussed.Armel Herve Nwabo Kamdje Paul Takam Kamga Richard Tagne Simo Lorella Vecchio Paul Faustin Seke Etet Jean Marc Muller Giulio Bassi Erique Lukong Raghuveera Kumar Goel Jeremie Mbo Amvene Mauro Krampera 2017Cancer Biology & Medicine2017,14,2:4
10Investigation of compensatory postures with videofluoromanometry in dysphagia patients显示文摘AIM: To investigate the effectiveness of head compensatory postures to ensure safe oropharyngeal transit. METHODS: A total of 321 dysphagia patients were enrolled and assessed with videofluoromanometry (VFM). The dysphagia patients were classified as follows: safe transit; penetration without aspiration; aspiration before, during or after swallowing; multiple aspirations and no transit. The patients with aspiration or no transit were tested with VFM to determine whether compensatory postures could correct their swallowing disorder. RESULTS: VFM revealed penetration without aspiration in 71 patients (22.1%); aspiration before swallowing in 17 patients (5.3%); aspiration during swallowing in 32 patients (10%); aspiration after swallowing in 21 patients (6.5%); multiple aspirations in six patients (1.9%); no transit in five patients (1.6%); and safe transit in 169 patients (52.6%). Compensatory postures guaranteed a safe transit in 66/75 (88%) patients with aspiration or no transit. A chin-down posture achieved a safe swallow in 42/75 (56%) patients, a head-turned posture in 19/75 (25.3%) and a hyperextended head posture in 5/75 (6.7%). The compensatory postures were not effective in 9/75 (12%) cases. CONCLUSION: VFM allows the speech-language therapist to choose the most effective compensatory posture without a trial-and-error process and check the effectiveness of the posture.Antonio Solazzo Luigi Monaco Lucia Del Vecchio Stefania Tamburrini Francesca Iacobellis Daniela Berritto Nunzia Luisa Pizza Alfonso Reginelli Natale Di Martino Roberto Grassi 2012World Journal of Gastroenterology2012,18,23:3
11Lumen-apposing metal stents for malignant biliary obstruction: Is this the ultimate horizon of our experience?显示文摘In the last years, endoscopic ultrasonography (EUS) has evolved from a purely diagnostic technique to a more and more complex interventional procedure, with the possibility to perform several type of therapeutic interventions. Among these, EUS-guided biliary drainage (BD) is gaining popularity as a therapeutic approach after failed endoscopic retrograde cholangiopancreatography in distal malignant biliary obstruction (MBO), due to the avoidance of external drainage, a lower rate of adverse events and re-interventions, and lower costs compared to percutaneous trans-hepatic BD. Initially, devices created for luminal procedures (e.g., luminal biliary stents) have been adapted to the new trans-luminal EUSguided interventions, with predictable shortcomings in technical success, outcome and adverse events. More recently, new metal stents specifically designed for transluminal drainage, namely lumen-apposing metal stents (LAMS), have been made available for EUS-guided procedures. An electrocautery enhanced delivery system (EC-LAMS), which allows direct access of the delivery system to the target lumen, has subsequently simplified the classic multi-step procedure of EUS-guided drainages. EUS-BD using LAMS and ECLAMS has been demonstrated effective and safe, and currently seems one of the most performing techniques for EUS-BD. In this Review, we summarize the evolution of the EUS-BD in distal MBO, focusing on the novelty of LAMS and analyzing the unresolved questions about the possible role of EUS as the first therapeutic option to achieve BD in this setting of patients.Andrea Anderloni Edoardo Troncone Alessandro Fugazza Annalisa Cappello Giovanna Del Vecchio Blanco Giovanni Monteleone Alessandro Repici 2019World Journal of Gastroenterology2019,25,29:3
12Familial colorectal cancer screening: When and what to do?显示文摘Colorectal cancer(CRC) is the third leading cause of death worldwide and represents a clinical challenge.Family members of patients affected by CRC have an increased risk of CRC development.In these individuals,screening is strongly recommended and should be started earlier than in the population with average risk,in order to detect neoplastic precursors,such as adenoma,advanced adenoma,and nonpolypoid adenomatous lesions of the colon.Fecal occult blood test(FOBT) is a non invasive,widespread screening method that can reduce CRC-related mortality.Sigmoidoscopy,alone or in addition to FOBT,represents another screening strategy that reduces CRC mortality.Colonoscopy is the best choice for screening highrisk populations,as it allows simultaneous detection and removal of preneoplastic lesions.The choice of test depends on local health policy and varies among countries.Giovanna Del Vecchio Blanco Omero Alessandro Paoluzi Pierpaolo Sileri Piero Rossi Giuseppe Sica Francesco Pallone 2015World Journal of Gastroenterology2015,21,26:3

17Hypolipidemic and anti-atherosclerogenic effects of aqueous extract of Ipomoea batatas leaves in diet-induced hypercholesterolemic rats显示文摘Objective:Ipomoea batatas(L.)Lam.is a food plant used in African traditional medicine to treat cardiovascular diseases and related conditions.We assessed the hypolipidemic and anti-atherosclerogenic properties of the aqueous extract of I.batatas leaves in a rat model of diet-induced hypercholesterolemia.Methods:Hypercholesterolemia was induced in male Wistar rats by exclusive feeding with a cholesterolenriched(1%)standard diet for four weeks.Then,rats were treated once daily(per os)with I.batatas extract at doses of 400,500 and 600 mg/kg or with atorvastatin(2 mg/kg),for four weeks.Following treatment,animals were observed for another four weeks and then sacrificed.Aortas were excised and processed for histopathological studies,and blood glucose level and lipid profile were measured.Results:Hypercholesterolemic animals experienced a 21.5%faster increase in body weight,significant increases in blood glucose and blood lipids(148.94%triglycerides,196.97%high-density lipoprotein cholesterol,773.04%low-density lipoprotein cholesterol,148.93%very low-density lipoprotein cholesterol and 210.42%total cholesterol),and increases in aorta thickness and atherosclerotic plaque sizes compared to rats fed standard diet.Treatment of hypercholesterolemic rats with the extract mitigated these alterations and restored blood glucose and blood lipid levels to normocholesterolemic values.Conclusion:Our findings suggest that I.batatas leaves have hypolipidemic and anti-atherosclerogenic properties and justify their use in traditional medicine.Fidele Ntchapda Fernand C.Tchatchouang David Miaffo Barthelemy Maidadi Lorella Vecchio Rodrigue E.Talla Christian Bonabe Paul F.Seke Etet Theophile Dimo 2021Journal of Integrative Medicine2021,19,3:2
