1Diagnosis and treatment of hepatocellular carcinoma: An update显示文摘Hepatocellular carcinoma(HCC) is one of the most common malignancies leading to high mortality rates in the general population; in cirrhotic patients, it is the primary cause of death. The diagnosis is usually delayed in spite of at-risk population screening recommendations, i.e., patients infected with hepatitis B or C virus. Hepatocarcinogenesis hinges on a great number of genetic and molecular abnormalities that lead to tumor angiogenesis and foster their dissemination potential. The diagnosis is mainly based on imaging studies such as computed tomography and magnetic resonance, in which lesions present a characteristic classical pattern of early arterial enhancement followed by contrast medium 'washout' in late venous phase. On occasion, when imaging studies are not conclusive, biopsy of the lesion must be performed to establish the diagnosis. The Barcelona Clinic Liver Cancer staging method is the most frequently used worldwide and recommended by the international guidelines of HCC management. Currently available treatments include tumor resection, liver transplant, sorafenib and locoregional therapies(alcoholization, radiofrequency ablation, chemoembolization). The prognosis of hepatocarcinoma is determined according to the lesion's stage and in cirrhotic patients, on residual liver function. Curative treatments, such as liver transplant, are sought in patients diagnosed in early stages; patients in more advanced stages, were not greatly benefitted by chemotherapy in terms of survival until the advent of target molecules such as sorafenib.Javier Tejeda-Maldonado Ignacio García-Juárez Jonathan Aguirre-Valadez Adrián González-Aguirre Mario Vilatobá-Chapa Alejandra Armengol-Alonso Francisco Escobar-Penagos Aldo Torre Juan Francisco Sánchez-ávila Diego Luis Carrillo-Pérez 2015World Journal of Hepatology2015,7,3:22
2冠状动脉内影像学临床应用专家共识(第一部分):对冠状动脉介入治疗的指导与优化显示文摘欧洲心血管介入协会(EAPCI)专家组系统总结了血管内超声(IVUS)和光学相干断层成像(OCT)这两种血管内影像学检查临床应用指征的现有证据,提供了关于IVUS和OCT指导经皮冠状动脉介入治疗(PCI)的应用价值,并明确了最可能从腔内影像学指导的介入治疗中获得临床收益的患者或病变类型,同时详细论述了PCI前如何使用IVUS或OCT优化支架尺寸(支架长度和直径)和手术策略的选择。此外,专家推荐对支架失败(支架内再狭窄或支架内血栓形成)的患者应常规进行冠状动脉内影像学检查,并首选OCT。最后,重点论述了IVUS和OCT在指导PCI和评估支架失败两个方面的优势和局限性,并对未来需要深入研究的领域进行了展望。Lorenz Raber Gary S Mintz Konstantinos C Koskinas Thomas W Johnson Niels R Holm Yoshinubo Onuma Maria D Radu Michael Joner Bo Yu Haibo Jia Nicolas Meneveau Jose M.de la Torre Hemandez Javier Escaned Jonathan Hill Francesco Prati Antonio Colombo Carlo di Mario Evelyn Regar Davide Capodanno William Wijns Robert A Byme Giulio Guagliumi 2019中华心血管病杂志2019,47,1:17

4Immunohistochemical expression of SP-NK-1R-EGFR pathway and VDR in colonic inflammation and neoplasia显示文摘AIM:To determine the expression of neurokinin-1receptor(NK-1R),phosphorylated epidermal growth factor receptor(p EGFR),cyclooxygenase-2(Cox-2),and vitamin D receptor(VDR)in normal,inflammatory bowel disease(IBD),and colorectal neoplasia tissues from Puerto Ricans.METHODS:Tissues from patients with IBD,colitisassociated colorectal cancer(CAC),sporadic dysplasia,and sporadic colorectal cancer(CRC),as well as normal controls,were identified at several centers in Puerto Rico.Archival formalin-fixed,paraffin-embedded tissues were de-identified and processed by immunohistochemistry for NK-1R,p EGFR,Cox-2,and VDR.Pictures of representative areas of each tissues diagnosis were taken and scored by three observers using a4-point scale that assessed intensity of staining.Tissues with CAC were further analyzed by photographing representative areas of IBD and the different grades of dysplasia,in addition to the areas of cancer,within each tissue.Differences in the average age between the five patient groups were assessed with one-way analysis of variance and Tukey-Kramer multiple comparisons test.The mean scores for normal tissues and tissues with IBD,dysplasia,CRC,and CAC were calculatedand statistically compared using one-way analysis of variance and Dunnett’s multiple comparisons test.Correlations between protein expression patterns were analyzed with the Pearson’s product-moment correlation coefficient.Data are presented as mean±SE.RESULTS:On average,patients with IBD were younger(34.60±5.81)than normal(63.20±6.13,P<0.01),sporadic dysplasia(68.80±4.42,P<0.01),sporadic cancer(74.80±4.91,P<0.001),and CAC(57.50±5.11,P<0.05)patients.NK-1R in cancer tissue(sporadic CRC,1.73±0.34;CAC,1.57±0.53)and sporadic dysplasia(2.00±0.45)were higher than in normal tissues(0.73±0.19).p EGFR was significantly increased in sporadic CRC(1.53±0.43)and CAC(2.25±0.47)when compared to normal tissue(0.07±0.25,P<0.05,P<0.001,respectively).Cox-2 was significantly increased in sporadic colorectal cancer(2.20±0.23 vs 0.80±0.37 for normal tissues,P<0.05).In comparison to normal(2.80±0.13)and CAC(2.50±0.33)tissues,VDR was significantly decreased in sporadic dysplasia(0.00±0.00,P<0.001 vs normal,P<0.001 vs CAC)and sporadic CRC(0.47±0.23,P<0.001 vs normal,P<0.001 vs CAC).VDR levels negatively correlated with NK-1R(r=-0.48)and p EGFR(r=-0.56)in normal,IBD,sporadic dysplasia and sporadic CRC tissue,but not in CAC.CONCLUSION:Immunohistochemical NK-1R and p EGFR positivity with VDR negativity can be used to identify areas of sporadic colorectal neoplasia.VDR immunoreactivity can distinguish CAC from sporadic cancer.Raymond A Isidro Myrella L Cruz Angel A Isidro Axel Baez Axel Arroyo William A González-Marqués Carmen González-Keelan Esther A Torres Caroline B Appleyard 2015World Journal of Gastroenterology2015,21,6:7
5Differential colorectal carcinogenesis:Molecular basis and clinical relevance显示文摘Colorectal cancer(CCR) is one of the most frequent cancers in developed countries.It poses a major public health problem and there is renewed interest in understanding the basic principles of the molecular biology of colorectal cancer.It has been established that sporadic CCRs can arise from at least two different carcinogenic pathways.The traditional pathway,also called the suppressor or chromosomal instability pathway,follows the Fearon and Vogelstein model and shows mutation in classical oncogenes and tumour suppressor genes,such as K-ras,adenomatous polyposis coli,deleted in colorectal cancer,or p53.Alterations in the Wnt pathway are also very common in this type of tumour.The second main colorectal carcinogenesis pathway is the mutator pathway.This pathway is present in nearly 15% of all cases of sporadic colorectal cancer.It is characterized by the presence of mutations in the microsatellite sequences caused by a defect in the DNA mismatch repair genes,mostly in hMLH1 or hMSH2.These two pathways have clear molecular differences,which will be reviewed in this article,but they also present distinct histopathological features.More strikingly,their clinical behaviours are completely different,having the 'mutator' tumours a better outcome than the 'suppressor' tumours.Alberto Morán Paloma Ortega Carmen de Juan Tamara Fernández-Marcelo Cristina Frías Andrés Sánchez-Pernaute Antonio José Torres Eduardo Díaz-Rubio Pilar Iniesta Manuel Benito 2010World Journal of Gastrointestinal Oncology2010,2,3:5
6Clinical scenarios for the use of S100β as a marker of hepatic encephalopathy显示文摘AIM: To evaluate the association between serum concentrations of S100β in patients with cirrhosis and the presence of low grade hepatic encephalopathy(HE).METHODS: This was a cross-sectional study. The population was categorized into four groups healthy subjects, cirrhosis without HE, cirrhosis with covert hepatic encephalopathy(CHE) and cirrhosis with overt HE. Kruskal-Wallis, Mann Whitney's U with Bonferroni adjustment Spearman correlations and area under the ROC were used as appropriate.RESULTS: A total of 61 subjects were included, 46 cirrhotic patients and 15 healthy volunteers. S100β values were different among all groups, and differences remained significant between groups 1 and 2(P < 0.001), and also between groups 2 and 3(P = 0.016), but not between groups 3 and 4. In cirrhotic patients with HE S100β was higher than in patients without HE [0.18(0.14-0.28) ng/m L vs 0.11(0.06-0.14) ng/m L, P < 0.001]. There was a close correlation between serum concentrations of S100β and psychometric hepatic encephalopathy score in patients with cirrhosis without HE compared to the patients with cirrhosis with CHE(r =-0.413, P = 0.019). ROC curve analysis yielded > 0.13 ng/m L as the best cutoff value of S100β for the diagnosis of HE(sensitivity 83.3%, specificity 63.6%).CONCLUSION: Serum concentrations of S100β are higher in patients with cirrhosis than in healthy volunteers, and are further increased in the presence of hepatic encephalopathy. The results suggest that serum biomarkers such as S100β could help in the correct characterization of incipient stages of HE.Andrés Duarte-Rojo Astrid Ruiz-Margáin Ricardo U Macias-Rodriguez Francisco Javier Cubero José Estradas-Trujillo Rosa Ma Munoz-Fuentes Aldo Torre 2016World Journal of Gastroenterology2016,22,17:4
7Factors that influence outcome in non-invasive and invasive treatment in polycystic liver disease patients显示文摘AIM: To evaluate the factors that influence outcome of both non-invasive and invasive treatment of polycystic liver disease. METHODS: Analysis of clinical files of patients with complete follow-up from July 1986 to June 2006. RESULTS: Forty-one patients (male, 7; female, 34), 47.8 ± 11.9 years age, and 5.7 ± 6.7 years follow-up, were studied. Alkaline phosphatase (AP) elevation (15% of patients) was associated with the requirement of invasive treatment (IT, P = 0.005). IT rate was higher in symptomatic than non-symptomatic patients (65.4% vs 14.3%, P = 0.002), and in women taking hormonal replacement therapy (HRT) (P = 0.001). Cysts complications (CC) were more frequent (22%) in the symptomatic patients group (P = 0.023). Patients with body mass index (BMI) > 25 (59%) had a trend to complications after IT (P = 0.075). Abdominal pain was the most common symptom (56%) and indication for IT (78%). Nineteen patients (46%) required a first IT: 12 open fenestration (OF), 4 laparoscopic fenestration (LF) and 3 fenestration with hepatic resection (FHR). Three required a second IT, and one required a third procedure. Complications due to first IT were found in 32% (OF 16.7%, LF 25%, FHR 66.7%), and in thesecond IT in 66.7% (OF 100%). Follow-up mortality rate was 0. CONCLUSION: Presence of symptoms, elevated AP, and CC are associated with IT requirement. HRT is associated with presence of symptoms and IT requirement. Patients with BMI > 25 have a trend be susceptible to IT complications. The proportions of complications are higher in FHR and second IT groups. RS is more frequent after OF.Josué Barahona-Garrido Jesús Camacho-Escobedo Eduardo Cerda-Contreras Jorge Hernández-Calleros Jesús K Yamamoto-Furusho Aldo Torre Misael Uribe 2008World Journal of Gastroenterology2008,14,20:4
8Low phase angle is associated with the development of hepatic encephalopathy in patients with cirrhosis显示文摘AIM Evaluate the association between phase angle and the development of hepatic encephalopathy in the longterm follow-up of cirrhotic patients.METHODS This was a prospective cohort study. Clinical, nutritional and biochemical evaluations were performed. MannWhitney's U and χ2 tests were used as appropriate. Kaplan-Meier curves and Cox proportional Hazards analysis were used to evaluate the prediction and incidence of hepatic encephalopathy.RESULTS Two hundred and twenty were included; the most frequent etiology of cirrhosis was hepatitis C infection, 52% of the patients developed hepatic encephalopathy(18.6% covert and 33.3% overt); the main precipitating factors were infections and variceal bleeding. KaplanMeier curves showed a higher proportion of HE in the group with low phase angle(39%) compared to the normal phase angle group(13%)(P = 0.012). Furthermore, creatinine and phase angle remained independently associated to hepatic encephalopathy in the Cox regression multivariate analysis [hazard ratio = 1.80(1.07-3.03)]. CONCLUSION In our cohort of patients low phase angle was associated with an increased incidence of hepatic encephalopathy. Phase angle is a useful nutritional marker that evaluates cachexia and could be used as a part of the integral assessment in patients with cirrhosis.Astrid Ruiz-Margáin Ricardo Ulises Macías-Rodríguez Javier Ampuero Francisco Javier Cubero Luis Chi-Cervera Silvia L Ríos-Torres Andrés Duarte-Rojo Ángeles Espinosa-Cuevas Manuel Romero-Gómez Aldo Torre 2016World Journal of Gastroenterology2016,22,45:4
9Management of Helicobacter pylori infection in Latin America: A Delphi technique-based consensus显示文摘AIM: To optimize diagnosis and treatment guidelines for this geographic region, a panel of gastroenterologists, epidemiologists, and basic scientists carried out a structured evaluation of available literature.METHODS: Relevant questions were distributed among the experts, who generated draft statements for consideration by the entire panel. A modified three-round Delphi technique method was used to reach consensus. Critical input was also obtained from representatives of the concerned medical community. The quality of the evidence and level of recommendation supporting each statement was graded according to United States Preventive Services Task Force criteria.RESULTS: A group of ten experts was established. The survey included 15 open-ended questions that were distributed among the experts, who assessed the articles associated with each question. The levels of agreement achieved by the panel were 50% in the first round, 73.3% in the second round and 100% in the third round. Main consensus recommendations included:(1) when available, urea breath and stool antigen test(HpSA) should be used for non-invasive diagnosis;(2) detect and eradicate Helicobacter pylori(H. pylori) in all gastroscopy patients to decrease risk of peptic ulcer disease, prevent o retard progression in patients with preneoplastic lesions, and to prevent recurrence in patients treated for gastric cancer;(3) further investigate implementation issues and health outcomes of H. pylorieradication for primary prevention of gastric cancer in high-risk populations;(4) prescribe standard 14-d triple therapy or sequential therapy for first-line treatment;(5) routinely assess eradication success post-treatment in clinical settings; and(6) select second- and third-line therapies according to antibiotic susceptibility testing.CONCLUSION: These achievable steps toward better region-specific management can be expected to improve clinical health outcomes.Antonio Rollan Juan Pablo Arab M Constanza Camargo Roberto Candia Paul Harris Catterina Ferreccio Charles S Rabkin Juan Cristóbal Gana Pablo Cortés Rolando Herrero Luisa Durán Apolinaria García Claudio Toledo Alberto Espino Nicole Lustig Alberto Sarfatis Catalina Figueroa Javier Torres Arnoldo Riquelme 2014World Journal of Gastroenterology2014,20,31:2
10Conservative management of perforated duodenal diverticulum: A case report and review of the literature显示文摘Duodenal diverticula are a relatively common condition. They are asymptomatic, unless they become complicated, with perforation being the rarest but most severe complication. Surgical treatment is the most frequently performed approach. We report the case of a patient with a perforated duodenal diverticulum, which was diagnosed early and treated conservatively with antibiotics and percutaneous drainage of secondary retroperitoneal abscesses. We suggest this method could be an acceptable option for the management of similar cases, provided that the patient is in good general condition and without septic signs.David Martínez-Cecilia Alvaro Arjona Sánchez Manuel Gómez álvarez Eva Torres Tordera Antonio Luque Molina Victor Valentí Azcárate Javier Briceo Delgado Francisco Javier Padillo Pedro López-Cillero Sebastián Rufián Pea 2008World Journal of Gastroenterology2008,14,12:2
