1Increased liver stiffness in alcoholic liver disease:Differentiating fibrosis from steatohepatitis显示文摘AIM:To test if inflammation also interferes with liver stiffness (LS) assessment in alcoholic liver disease (ALD) and to provide a clinical algorithm for reliable fibrosis assessment in ALD by FibroScan (FS).METHODS:We first performed sequential LS analysis before and after normalization of serum transaminases in a learning cohort of 50 patients with ALD admitted for alcohol detoxification. LS decreased in almost all patients within a mean observation interval of 5.3 d. Six patients (12%) would have been misdiagnosed with F3and F4 fibrosis but LS decreased below critical cut-off values of 8 and 12.5 kPa after normalization of trans-aminases. RESULTS:Of the serum transaminases,the decrease in LS correlated best with the decrease in glutamic oxaloacetic transaminase (GOT). No significant chang-es in LS were observed below GOT levels of 100 U/L. After establishing the association between LS and GOT levels,we applied the rule of GOT < 100 U/L for reliable LS assessment in a second validation cohort of 101 patients with histologically confi rmed ALD. By ex-cluding those patients with GOT > 100 U/L at the time of LS assessment from this cohort,the area under the receiver operating characteristic (AUROC) for cirrhosis detection by FS improved from 0.921 to 0.945 while specificity increased from 80% to 90% at a sensitivity of 96%. A similar AUROC could be obtained for lower F3 fibrosis stage if LS measurements were restricted to patients with GOT < 50 U/L. Histological grading of inflammation did not further improve the diagnostic accuracy of LS.CONCLUSION:Coexisting steatohepatitis markedly increases LS in patients with ALD independent of fibrosis stage. Postponing cirrhosis assessment by FS during alcohol withdrawal until GOT decreases to < 100 U/mL signif icantly improves the diagnostic accuracy.Sebastian Mueller Gunda Millonig Lucie Sarovska Stefanie Friedrich Frank M Reimann Maria Pritsch Silke Eisele Felix Stickel Thomas Longerich Peter Schirmacher Helmut Karl Seitz 2010World Journal of Gastroenterology2010,16,8:10
2Treatment of early gastric cancer in the Western World显示文摘The incidence rate of gastric cancer is much higher in Asia than in the Western industrial nations.According to the different screening programs in Japan and Korea about fifty percent of treated patients had an early tumor stage.In contrast,European and American patients with gastric cancer had an advanced tumor stage.Therefore,the experience for the various therapeutic options for gastric cancer may be different between these regions.In this review we tried to point out the treatment modalities in Western industrial countries for early gastric cancer.Elfriede Bollschweiler Felix Berlth Christoph Baltin Stefan Mnig Arnulf H Hlscher 2014World Journal of Gastroenterology2014,20,19:8

4Prevalence of metabolic syndrome, obesity and diabetes type 2 in cryptogenic cirrhosis显示文摘AIM: To evaluate the prevalence of metabolic syndrome (MS), obesity and type 2 diabetes mellitus (T2DM) in a group of Mexican Mestizo patients with cryptogenic cirrhosis (CC) and to compare this group with patients with cirrhosis secondary to other causes (disease controls). METHODS: Patients with CC, diagnosed between January, 1990 and April, 2005, were included in a retrospective study. Patients with cirrhosis caused by chronic hepatitis C, alcohol abuse or autoimmune hepatitis (AIH) served as disease controls. RESULTS: A total of 134 patients with CC were analyzed. Disease controls consisted of 81 patients with chronic hepatitis C, 33 with alcohol abuse and 20 with AIH. The median age of patients with CC was 57 years (range, 16-87); 83 (61.9%) patients were female; 53 (39.6%) were Child A, 65 (48.5%) Child B, and 16 (11.9%) were Child C cirrhosis. The prevalence of MS (29.1% vs 6%; P < 0.001), obesity (16.4% vs 8.2%; P = 0.04) and T2DM (40% vs 22.4%; P = 0.013) was higher in CC patients than in disease controls. There were no differences in sex, age or liver function tests between the two groups. CONCLUSION: The prevalence of MS, obesityand T2DM were higher in patients with CC than in patients with cirrhosis secondary to others causes. Our findings support the hypothesis that non-alcoholic steatohepatitis (NASH) plays an under-recognized role in CC.Felix I Tellez-Avila Francisco Sanchez-Avila Mauricio García-Saenz-de-Sicilia Norberto C Chavez-Tapia Ada M Franco-Guzman Gustavo Lopez-Arce Eduardo Cerda-Contreras Misael Uribe 2008World Journal of Gastroenterology2008,14,30:6
5Adult-to-adult right lobe living donor liver transplantation:Comparison of endoscopic retrograde cholangiography with standard T2-weighted magnetic resonance cholangiography for evaluation of donor biliary anatomy显示文摘AIM: To compare the value of endoscopic retrograde cholangiography (ERC) and standard T2-weighted magnetic resonance cholangiography (MRC) in the evaluation process as adult-to-adult right lobe living donor liver transplantation (LDLTx) demands a successful outcome, and exact knowledge of the biliary tree is implicated to avoid biliary complications, postoperatively.METHODS: After starting the LDLTx program, 18 liver transplant candidates were selected for LDLTx by a stepwise evaluation process. ERC and standard T2-weighted MRC were performed to evaluate the biliary system of the donor liver. The anatomical findings of ERC and MRC mapping were compared using the Ohkubo classification. RESULTS: ERC allowed mapping of the whole biliary system in 15/15 (100%) cases, including 14/15 (93.3%) with biliary variants while routine MRC was only accurate in 2/13 (15.4%) cases. MRC was limited in depicting the biliary system proximal of the hepatic bifurcation. Postoperative biliary complications occurred in 2 donors and 8 recipients. Biliary complications were associated with Ohkubo type C, E or G in 6/8 recipients, and 2/3 recipients with biliary leak received a graft with multiple (≥2) bile ducts. CONCLUSION: Pretransplant ERC is safe and superior over standard MRC for detection of biliary variations that occur with a high frequency. However, precise knowledge of biliary variants did not reduce the incidence of postoperative biliary complications.Perdita Wietzke-Braun Felix Braun Dieter Müller Thomas Lorf Burckhardt Ringe Giuliano Ramadori 2006World Journal of Gastroenterology2006,12,36:5
6Arachidyl amido cholanoic acid improves liver glucose and lipid homeostasis in nonalcoholic steatohepatitis via AMPK and mTOR regulation显示文摘BACKGROUND Arachidyl amido cholanoic acid(Aramchol)is a potent downregulator of hepatic stearoyl-CoA desaturase 1(SCD1)protein expression that reduces liver triglycerides and fibrosis in animal models of steatohepatitis.In a phase IIb clinical trial in patients with nonalcoholic steatohepatitis(NASH),52 wk of treatment with Aramchol reduced blood levels of glycated hemoglobin A1c,an indicator of glycemic control.AIM To assess lipid and glucose metabolism in mouse hepatocytes and in a NASH mouse model[induced with a 0.1%methionine and choline deficient diet(0.1MCD)]after treatment with Aramchol.METHODS Isolated primary mouse hepatocytes were incubated with 20μmol/L Aramchol or vehicle for 48 h.Subsequently,analyses were performed including Western blot,proteomics by mass spectrometry,and fluxomic analysis with 13C-uniformly labeled glucose.For the in vivo part of the study,male C57BL/6J mice were randomly fed a control or 0.1MCD for 4 wk and received 1 or 5 mg/kg/d Aramchol or vehicle by intragastric gavage for the last 2 wk.Liver metabolomics were assessed using ultra-high-performance liquid chromatography-time of flight-MS for the determination of glucose metabolism-related metabolites.RESULTS Combination of proteomics and Western blot analyses showed increased AMPK activity while the activity of nutrient sensor mTORC1 was decreased by Aramchol in hepatocytes.This translated into changes in the content of their downstream targets including proteins involved in fatty acid(FA)synthesis and oxidation[PACCα/β(S79),SCD1,CPT1A/B,HADHA,and HADHB],oxidative phosphorylation(NDUFA9,NDUFB11,NDUFS1,NDUFV1,ETFDH,and UQCRC2),tricarboxylic acid(TCA)cycle(MDH2,SUCLA2,and SUCLG2),and ribosome(P-p70S6K[T389]and P-S6[S235/S236]).Flux experiments with 13Cuniformely labeled glucose showed that TCA cycle cataplerosis was reduced by Aramchol in hepatocytes,as indicated by the increase in the number of rounds that malate remained in the TCA cycle.Finally,liver metabolomic analysis showed that glucose homeostasis was improved by Aramchol in 0.1MCD fed mice in a dose-dependent manner,showing normalization of glucose,G6P,F6P,UDP-glucose,and Rbl5P/Xyl5P.CONCLUSION Aramchol exerts its effect on glucose and lipid metabolism in NASH through activation of AMPK and inhibition of mTORC1,which in turn activate FAβ-oxidation and oxidative phosphorylation.David Fernández-Ramos Fernando Lopitz-Otsoa Laura Delacruz-Villar Jon Bilbao Martina Pagano Laura Mosca Maider Bizkarguenaga Marina Serrano-Macia Mikel Azkargorta Marta Iruarrizaga-Lejarreta Jesús Sot Darya Tsvirkun Sebastiaan Martijn van Liempd Felix M Goni Cristina Alonso María Luz Martínez-Chantar Felix Elortza Liat Hayardeny Shelly C Lu JoséM Mato 2020World Journal of Gastroenterology2020,26,34:5
7Sedated vs unsedated colonoscopy:A prospective study显示文摘AIM:To compare sedated to unsedated colonoscopy in terms of duration,pain and the patient’s willingness to repeat the procedure.METHODS:Consecutive patients who underwent colonoscopies over a 2-year period were invited to participate.All patients who were to undergo our endoscopy unit were offered sedation with standard intravenous sedatives and analgesics,or an unsedated colonoscopy was attempted.Demographic details were recorded.The patient anxiety level prior to the procedure,time to reach the cecum,total discharge time,patient and endoscopist pain assessments,satisfaction after the examination and the patient’s willingness to return for the same procedure in the future were recorded.RESULTS:Among the 403 observed patients,more males were observed in the unsedated group(66.2%vs 55.2%,P=0.04).Additionally,the unsedated group patients were less anxious prior to the procedure(5.1vs 6.0,P<0.01).The colonoscopy completion rates were comparable between the 2 groups(85.9%vs84.2%,P=0.66).The time to reach the cecum was also comparable(12.2 min vs 11.8 min);however,the total discharge times were shorter in the unsedated group(20.7 min vs 83.0 min,P<0.01).Moreover,the average patient pain score(3.4 vs 5.7,P<0.01)was lower in the sedated group,while the satisfaction score(8.8 vs 7.8,P<0.01)was significantly higher.There was no significant difference,however,between the groups in terms of willingness to repeat the procedure if another was required in the future(83.3%vs 77.3%,P=0.17).CONCLUSION:Unsedated colonoscopy is feasible in willing patients.The option saves the endoscopy units up to one hour per patient and does not affect the patient willingness to return to the same physician again for additional colonoscopies if a repeated procedure is needed.Abdulrahman M Aljebreen Majid A Almadi Felix W Leung 2014World Journal of Gastroenterology2014,20,17:3

9Sedation-risk-free colonoscopy for minimizing the burden of colorectal cancer screening显示文摘Unsedated colonoscopy is available worldwide,but is not a routine option in the United States(US).We conducted a literature review supplemented by our experience and expert commentaries to provide data to support the use of unsedated colonoscopy for colorectal cancer screening.Medline data from 1966 to 2009 were searched to identify relevant articles on the subject.Data were summarized and co-authors provided critiques as well as accounts of unsedated colonoscopy for screening and surveillance.Diagnostic colonoscopy was initially dev eloped as an unsedated procedure.Procedure-re lated discomfort led to wide adoption of sedation in the US,although unsedated colonoscopy remains the usual practice elsewhere.The increased use of colonoscopy for colorectal cancer screening in healthy,asymptomatic individuals suggests a reass-essment of the burden of sedation in colonoscopy for screening is appropriate in the US for lowering costs and minimizing complications for patients.A water method developed to minimize discomfort has shown promise to enhance outcomes of unsedated colonoscopy.The use of scheduled,unsedated colono scopy in the US appears to be feasible for colorectal cancer screening.Studies to assess its applicability in diverse practice settings deserve to be conducted and supported.Felix W Leung Abdulrahman M Aljebreen Emilio Brocchi Eugene B Chang Wei-Chih Liao Takeshi Mizukami Melvin Schapiro Konstantinos Triantafyllou 2010World Journal of Gastrointestinal Endoscopy2010,2,3:3

12Serotonin type 3 receptor subunit gene polymorphisms associated with psychosomatic symptoms in irritable bowel syndrome:A multicenter retrospective study显示文摘BACKGROUND Single-nucleotide polymorphisms(SNPs)of the serotonin type 3 receptor subunit(HTR3)genes have been associated with psychosomatic symptoms,but it is not clear whether these associations exist in irritable bowel syndrome(IBS).AIM To assess the association of HTR3 polymorphisms with depressive,anxiety,and somatization symptoms in individuals with IBS.METHODS In this retrospective study,623 participants with IBS were recruited from five specialty centers in Germany,Sweden,the United States,the United Kingdom,and Ireland.Depressive,anxiety,and somatization symptoms and sociodemographic characteristics were collected.Four functional SNPs—HTR3A c.-42C>T,HTR3B c.386A>C,HTR3C c.489C>A,and HTR3E c.*76G>A—were genotyped and analyzed using the dominant and recessive models.We also performed separate analyses for sex and IBS subtypes.SNP scores were calculated as the number of minor alleles of the SNPs above.The impact of HTR3C c.489C>A was tested by radioligand-binding and calcium influx assays.RESULTS Depressive and anxiety symptoms significantly worsened with increasing numbers of minor HTR3C c.489C>A alleles in the dominant model(F_(depressive)=7.475,P_(depressive)=0.006;F_(anxiety)=6.535,P_(anxiety)=0.011).A higher SNP score(range 0-6)was linked to a worsened depressive symptoms score(F=7.710,P-linear trend=0.006)in IBS.The potential relevance of the HTR3C SNP was corroborated,showing changes in the expression level of 5-HT3AC variant receptors.CONCLUSION We have provided the first evidence that HTR3C c.489C>A is involved in depressive and anxiety symptoms in individuals with IBS.The SNP score indicated that an increasing number of minor alleles is linked to the worsening of depressive symptoms in IBS.Sabrina Berens Yuanjun Dong Nikola Fritz Jutta Walstab Mauro D'Amato Tenghao Zheng Verena Wahl Felix Boekstegers Justo Lorenzo Bermejo Cristina Martinez Stefanie Schmitteckert Egbert Clevers Felicitas Engel Annika Gauss Wolfgang Herzog Robin Spiller Miriam Goebel-Stengel Hubert Mönnikes Viola Andresen Frieling Thomas Jutta Keller Christian Pehl Christoph Stein-Thöringer Gerard Clarke Timothy G Dinan Eamonn M Quigley Gregory Sayuk Magnus Simrén Jonas Tesarz Gudrun Rappold Lukas van Oudenhove Rainer Schaefert Beate Niesler 2022World Journal of Gastroenterology2022,28,21:2
13拉科酰胺在癫痫持续状态中的应用--针对现有证据的系统评价显示文摘拉科酰胺(Lacosamide,LCM)的静脉制剂具有良好的耐受性和安全性,促使其在癫痫持续状态(Status Epilepticus,SE)中得到应用。本项系统评价的目的是确定和评估LCM在SE中的使用情况。在电子数据库中用联合检索方式对2008年—2016年10月的文献进行了系统检索,并使用标准化的评估表格从各项研究中将有关研究设计、方法框架、数据源、有效性和LCM引起的不良反应的信息进行提取并系统地报告。研究共评估了522次SE发作,其中包括486例成人和36例儿童及青少年发作,女性占51.7%。LCM的总体效力为57%。LCM对非惊厥性(57%,82/145)和全面痉挛性(61%,30/49,P=0.68)SE的效力相似,但对局灶运动性SE的总体有效率更高(92%,34/39,P<0.001)。而LCM在用药次序靠后时其疗效从100%下降到20%。治疗期间的主要不良反应是眩晕,视力异常,复视和共济失调。总体而言,LCM具有良好的耐受性,并且没有具临床意义的药物相互作用。现有数据表明LCM在SE中的使用是有前景的,有效率为57%。LCM的优势在于没有潜在的药物相互作用,并且在紧急情况需迅速增加剂量时可静脉使用。Adam Strzelczyk Johann Philipp Zollner Laurent M Willems 肖英凤 童馨 慕洁 Julie Jost Esther Paule Susanne Schubert-Bast Felix Rosenow Sebastian Bauer 2018癫痫杂志2018,4,5:2
14Significance of an additional unenhanced scan in computed tomography angiography of patients with suspected acute aortic syndrome显示文摘AIM To assess potential benefits of an additional unenhanced acquisition in computed tomography angiography(CTA) in patients with suspected acute aortic syndrome(AAS).METHODS A total of 103 aortic CTA(non-electrocardiography-gated, 128 slices) performed due to suspected AAS were retrospectively evaluated for acute aortic dissection(AAD), intramural hematoma(IMH), or penetrating aortic ulcer(PAU). Spiral CTA protocol consisted of an unenhanced acquisition and an arterial phase. If AAS was detected, a venous phase(delay, 90 s) was added. Images were evaluated for the presence and extent of AAD, IMH, PAU, and related complications. The diagnostic benefit of the unenhanced acquisition was evaluated concerning detection of IMH.RESULTS Fifty-six(30% women; mean age, 67 years; median, 68 years) of the screened individuals had AAD or IMH. A triphasic CT scan was conducted in 76.8%(n =43). 56% of the detected AAD were classified as Stanford type A, 44% as Stanford type B. 53.8% of the detected IMH were classified as Stanford type A, 46.2% as Stanford type B. There was no significant difference in the involvement of the ascending aorta between AAD and IMH(P = 1.0) or in the average age between AAD and IMH(P = 0.548), between Stanford type A and Stanford type B in general(P = 0.650) and between Stanford type A and Stanford type B within the entities of AAD and IMH(AAD: P = 0.785; IMH: P = 0.146). Only the unenhanced acquisitions showed a significant density difference between the adjacent lumen and the IMH(P = 0.035). Subadventitial hematoma involving the pulmonary trunk was present in 5 patients(16%) with Stanford A AAD. The difference between the median radiation exposure of a triphasic(2737 mGy*cm) compared to a biphasic CT scan(2135 mGy*cm) was not significant(P = 0.135).CONCLUSION IMH is a common and difficult to detect entity of AAS. An additional unenhanced acquisition within an aortic CTA protocol facilitates the detection of IMH.Nikolaos Panagiotopoulos Felix Drüschler Martin Simon Florian M Vogt Sebastian Wolfrum Steffen Desch Doreen Richardt Jorg Barkhausen Peter Hunold 2018World Journal of Radiology2018,10,11:2
