| 1 | Characterization of monocarboxylate transporter activity in hepatocellular carcinoma显示文摘AIM: To assess the immunoexpression of hypoxiarelated markers in samples from cirrhosis and primary and metastatic hepatocellular carcinoma(HCC).METHODS: From a total of 5836 autopsies performed at the Pathology Department- University of Sao Paulo School of Medicine Hospital- from 2003 to 2009, 188 presented primary liver tumors. Immunohistochemical reactivity for monocarboxylate transporters(MCTs)-1, 2 and 4, CD147 and glucose transporter-1(GLUT1)was assessed in necropsies from 80 cases of HCC. Data were stored and analyzed using the IBM SPSS statistical software(version 19, IBM Company, Armonk, NY). All comparisons were examined for statistical significance using Pearson's χ2 test and Fisher's exact test(when n < 5). The threshold for significant P values was established as P < 0.05.RESULTS: Plasma membrane expression of MCT4 and overall expression of GLUT1 showed progressively higher expression from non-neoplastic to primary HCC and to metastases. In contrast, overall expression of MCT2 was progressively decreased from non-neoplastic to primary HCC and to metastases. MCT1(overall and plasma membrane expression), MCT2 and CD147 plasma membrane expression were associated with absence of cirrhosis, while plasma membrane expression of CD147 was also associated with absence of HBV infection. MCT2 overall expression was associated with lower liver weight, absence of metastasis and absence of abdominal dissemination. Additionally, MCT4 plasma membrane positivity was strongly associated with Ki-67 expression. CONCLUSION: MCT4 and GLUT1 appear to play a role in HCC progression, while MCT2 is lost during progression and associated with better prognosis. | Venncio AF Alves Céline Pinheiro Filipa Morais-Santos Aloisio Felipe-Silva Adhemar Longatto-Filho Fátima Baltazar | 2014 | World Journal of Gastroenterology2014，20，33： | 11 |
| 2 | Role of endoglin and VEGF family expression in colorectal cancer prognosis and anti-angiogenic therapies显示文摘Colorectal cancer(CRC)is one of the cancer models and most of the carcinogenic steps are presently well understood.Therefore,successful preventive measures are currently used in medical practice.However,CRC is still an important public health problem as it is the third most common cancer and the fourth most frequent cause of cancer death worldwide.Nowadays,pathologic stage is a unique and well-recognized prognostic indicator,however,more accurate indicators of the biologic behavior of CRC are expected to improve the specificity of medical treatment.Angiogenesis plays an important role in the growth and progression of cancer but its role as a prognostic factor is still controversial.Probably the most important clinical implication of tumor angiogenesis is the development of anti-angiogenic therapy.The goal of this review is to critically evaluate the role of angiogenic markers,assessed by either endoglin-related microvessel density or expression of vascular endothelial growth factor family members in the CRC setting and discuss the role of these angiogenic markers in antiangiogenic therapies. | Sandra F Martins Rui M Reis Antonio Mesquita Rodrigues Fátima Baltazar Adhemar Longatto Filho | 2011 | World Journal of Clinical Oncology2011，2，6： | 9 |
| 3 | Autoimmune hepatitis and anti-tumor necrosis factor alpha therapy:A single center report of 8 cases显示文摘This article describes cases of anti-tumor necrosis factor(TNF)-α-induced autoimmune hepatitis and evaluates the outcome of these patients in relation to their immunosuppressive strategy. A retrospective analysis of medical records was performed in our center, in order to detect cases of autoimmune hepatitis(AIH) associated with anti-TNF biologic agents. We describe and analyze eight cases of AIH following anti-TNF therapy, 7 with infliximab and 1 with adalimumab. A distinction should be made between induction of autoimmunity and clinically evident autoimmune disease. Liver biopsy is useful in detecting the role of the TNF-α antagonist in the development of AIH. The lack of relapse after discontinuing immunosuppressive therapy favors, as in this case series, an immune-mediated drug reaction as most patients with AIH have a relapse after treatment is suspended. Although AIH related to anti-TNF therapy is rare, a baseline immunological panel along with liver function tests should be performed in all patients with autoimmune disease before starting biologics. | Susana Rodrigues Susana Lopes Fernando Magro Hélder Cardoso Ana Maria Horta e Vale Margarida Marques Eva Mariz Miguel Bernardes Joanne Lopes Fátima Carneiro Guilherme Macedo | 2015 | World Journal of Gastroenterology2015，21，24： | 9 |
| 4 | Metadoxine improves the three- and six-month survival rates in patients with severe alcoholic hepatitis显示文摘AIM:To evaluate the impact of metadoxine(MTD) on the 3- and 6-mo survival of patients with severe alcoholic hepatitis(AH).METHODS:This study was an open-label clinical trial,performed at the'Hospital General de México,Dr.Eduardo Liceaga'.We randomized 135 patients who met the criteria for severe AH into the following groups:35 patients received prednisone(PDN)40 mg/d,35patients received PDN+MTD 500 mg three times daily,33 patients received pentoxifylline(PTX)400 mg three times daily,and 32 patients received PTX+MTD 500 mg three times daily.The duration of the treatment for all of the groups was 30 d.RESULTS:In the groups treated with the MTD,thesurvival rate was higher at 3 mo(PTX+MTD 59.4%vs PTX 33.3%,P=0.04;PDN+MTD 68.6%vs PDN20%,P=0.0001)and at 6 mo(PTX+MTD 50%vs PTX18.2%,P=0.01;PDN+MTD 48.6%vs PDN 20%,P=0.003)than in the groups not treated with MTD.A relapse in alcohol intake was the primary independent factor predicting mortality at 6 mo.The patients receiving MTD maintained greater abstinence than those who did not receive it(74.5%vs 59.4%,P=0.02).CONCLUSION:MTD improves the 3-and 6-mo survival rates in patients with severe AH.Alcohol abstinence is a key factor for survival in these patients.The patients who received the combination therapy with MTD were more likely to maintain abstinence than those who received monotherapy with either PDN or PTX. | Fátima Higuera-de la Tijera Alfredo I Servín-Caamano Aurora E Serralde-Zúniga Javier Cruz-Herrera Eduardo Pérez-Torres Juan M Abdo-Francis Francisco Salas-Gordillo JoséL Pérez-Hernández | 2015 | World Journal of Gastroenterology2015，21，16： | 8 |
| 5 | SIRT3-mediated inhibition of FOS through histone H3 deacetylation prevents cardiac fibrosis and inflammation显示文摘Sirtuin 3(SIRT3)is a deacetylase that modulates proteins that control metabolism and protects against oxidative stress.Modulation of SIRT3 activity has been proposed as a promising therapeutic target for ameliorating metabolic diseases and associated cardiac disturbances.In this study,we investigated the role of SIRT3 in inflammation and fibrosis in the heart using male mice with constitutive and systemic deletion of SIRT3 and human cardiac AC16 cells.SIRT3 knockout mice showed cardiac fibrosis and inflammation that was characterized by augmented transcriptional activity of AP-1.Consistent with this,SIRT3 overexpression in human and neonatal rat cardiomyocytes partially prevented the inflammatory and profibrotic response induced by TNF-α.Notably,these effects were associated with a decrease in the mRNA and protein levels of FOS and the DNA-binding activity of AP-1.Finally,we demonstrated that SIRT3 inhibits FOS transcription through specific histone H3 lysine K27 deacetylation at its promoter.These findings highlight an important function of SIRT3 in mediating the often intricate profibrotic and proinflammatory responses of cardiac cells through the modulation of the FOS/AP-1 pathway.Since fibrosis and inflammation are crucial in the progression of cardiac hypertrophy,heart failure,and diabetic cardiomyopathy,our results point to SIRT3 as a potential target for treating these diseases. | Xavier Palomer MSilvia Román-Azcona Javier Pizarro-Delgado Ana Planavila Francesc Villarroya Brenda Valenzuela-Alcaraz Fátima Crispi Álvaro Sepúlveda-Martínez Irene Miguel-Escalada Jorge Ferrer JFrancisco Nistal Raquel García Mercy MDavidson Emma Barroso Manuel Vázquez-Carrera | 2020 | Signal Transduction and Targeted Therapy2020，5，1： | 7 |
| 6 | Metabolic syndrome and colorectal neoplasms:An ominous association显示文摘AIM:To evaluate the association of metabolic syndrome(MS) and colorectal cancer and adenomas in a Western country,where the incidence of MS is over 27%.METHODS:This was a prospective study between March 2013 and March 2014.MS was diagnosed according to the National Cholesterol Education ProgramATP III.Demographic characteristics,anthropometric measurements,metabolic risk factors,and colonoscopic pathologic findings were assessed in patients with MS(group 1) who underwent routine colonoscopy at our department.This data was compared with consecutive patients without metabolic syndrome(group 2),with no differences regarding sex and age.Patients with incomplete colonoscopy,family history,or past history of colorectal neoplasm were excluded.Informed consent was obtained and the ethics committee approved this study.Statistical analysis was performed using Student's t-test and χ2 test,with a P value ≤ 0.05 being considered statistically significant.RESULTS:Of 258 patients,129 had MS;51% males;mean-age 67.1 years(50-87).Among the MS group,94% had high blood pressure,91% had increased waist circumference,60% had diabetes,55% had low high-density lipoprotein cholesterol level,50% had increased triglyceride level,and 54% were obese [body mass index(BMI) 30 kg/m2].51% presented 4 criteria of MS.MS was associated with increased prevalence of adenomas(43% vs 25%,P = 0.004) and colorectal cancer(13% vs 5%,P = 0.027),compared with patients without MS.MS was also positively associated with multiple(≥ 3) adenomas(35% vs 9%,P = 0.024) and sessile adenomas(69% vs 53%,P = 0.05).No difference existed between location(P = 0.086),grade of dysplasia(P = 0.196),or size(P= 0.841) of adenomas.In addition,no difference was found between BMI(P = 0.078),smoking(P = 0.146),alcohol consumption(P = 0.231),and the presence of adenomas.CONCLUSION:MS is positively associated with adenomas and colorectal cancer.However,there is not enough information in western European countries to justify screening in patients with MS.To our knowledge,no previous study has evaluated this association in Portuguese patients. | Daniel Trabulo Suzane Ribeiro Cláudio Martins Cristina Teixeira Cláudia Cardoso Jo?o Mangualde Ricardo Freire élia Gamito Ana L Alves Fátima Augusto Ana P Oliveira Isabelle Cremers | 2015 | World Journal of Gastroenterology2015，21，17： | 5 |
| 7 | Exercise manual for liver disease patients显示文摘AIM: To increase inspiratory muscle strength and improve the quality of life of candidates for liver transplantation.METHODS: Twenty-three candidates for liver transplantation participated in the control group and 14 made up the intervention group. The control group consisted of 18 men and 5 women, body mass index(BMI) 27.3 ± 4.5 kg/m2 and Model for End-Stage Liver Disease(MELD) 18.2 ± 6.1. The intervention group consisted of 11 men and 3 women, BMI 28.6 ± 5.4 kg/m2 and MELD 18 ± 4.5. The presence or absence of ascites was identified in the first patient evaluation and after three months. We evaluated maximal inspiratory pressure(MIP) and maximal expiratory pressure, spirometry, root mean square(RMS) of diaphragm and rectus abdominis, and the quality of life. The exercises were performed daily by patients at home for three months and were supervised at distance monthly. The manual consisted of diaphragmatic breathing exercises, diaphragmatic isometric exercise, Threshold IMT®, lifting upper limbs with a bat and strengthening the abdomen. RESULTS: There was significant difference(P = 0.01) between the first(initial) and the third month(final) MIP in the control group and in the intervention group, but there was no difference(P = 0.45) between the groups.The RMS of the diaphragm was lower(P = 0.001) and the functional capacity was higher(P = 0.006) in the intervention group compared to the control. The general health and mental health domains received higher scores after three months in the control group(P = 0.01) and the intervention group(P = 0.004), but there was no significant difference between them. The comparison between the presence of initial ascites with the presence of ascites was performed after three months in the control group(P = 0.083) and intervention group(P = 0.31). There was no significant difference, in relation to the presence of ascites after three months between groups(P = 0.21). In the intervention group, patients with ascites at the end of the time period had decreased scores on the social aspects SF-36 domain(P = 0.023) compared to those who had no ascites. CONCLUSION: The proposed exercises provide an increase in the inspiratory muscle strength and improve functional capacity, consequently bettering the quality of life of liver disease patients. | Vivian Limongi Daniele Costa Dos Santos Aurea Maria de Oliveira da Silva Ilka de Fátima Santana Ferreira Boin Raquel Silveira Bello Stucchi | 2016 | World Journal of Transplantation2016，6，2： | 3 |
| 8 | Malnutrition negatively impacts the quality of life of patients with cirrhosis: An observational study显示文摘AIM To verify how malnutrition is related to health-related quality of life(HRQL) impairment in patients with cirrhosis.METHODS Data was retrospectively abstracted from medical records and obtained by direct interview. We included patients with cirrhosis from any etiology, evaluated at the Liver Clinic from Gastroenterology Department in a tertiary healthcare center, from June 2014 to June 2016. Child-Pugh score, data about complications, and demographic, clinical and anthropometric characteristics of patients were obtained. Nutritional status was evaluated by the Subjective Global Assessment(SGA). HRQL was evaluated through the Chronic Liver Disease Questionnaire. Patients were requested to assess their global HRQL with the following code: 0 = impairment of HRQL, when it was compared with other healthy subjects; 1 = good HRQL, if it was similar to the quality of life of other healthy subjects. To compare the primary outcome between malnourished and well-nourished groups, the χ~2 test, Fisher's exact test or Student's t-test were used, based on the variable type. Associations between predictor variables and deterioration of HRQL were determined by calculating the hazard ratio and 95% confidence interval using Cox proportional hazards regression. RESULTS A total of 127 patients with cirrhosis were included, and the mean age was 54.1 ± 12.3 years-old. According to Child-Pugh scoring, 25(19.7%) were classified as A(compensated), 76(59.8%) as B, and 26(20.5%) as C(B/C = decompensated). According to SGA, 58(45.7%) patients were classified as well-nourished. Sixty-nine patients identified HRQL as good, and 76 patients(59.8%) perceived impairment of their HRQL. Multivariate analysis to determine associations between predictor variables and self-perception of an impairment of HRQL found strong association with malnutrition(P < 0.0001). The most important impaired characteristics in malnourished patients were: Presence of body pain, dyspnea on exertion with daily activities, decreased appetite, generalized weakness, trouble lifting or carrying heavy objects, and decreased level of energy(P < 0.0001).CONCLUSION Malnutrition is a key factor related to impairment of HRQL in patients with cirrhosis. | Gabriela Rojas-Loureiro Alfredo Servín-Caamano Elizabeth Pérez-Reyes Luis Servín-Abad Fátima Higuerade la Tijera | 2017 | World Journal of Hepatology2017，9，5： | 3 |
| 9 | Systematic review of noninvasive treatments to arrest dentin non-cavitated caries lesions显示文摘AIM: To systematically review the literature on the efficacy of noninvasive methods of arresting the progression of non-cavitated occlusal carious lesions in dentin.METHODS: The Medline/Pub Med,LILACS,Sci ELO and Scopus databases were searched to identify relevant publications through to November 2013.Only clinical trials evaluating the ability of noninvasive methods to arrest the progression of occlusal non-cavitated carious lesions in dentin were included.Screening,data extraction and quality assessment were conducted independently and in duplicate.RESULTS: Of 167 citations identified,nine full text articles were screened and five were included in the analysis.All papers reported on occlusal fissure sealing using a self-curing glass ionomer(n = 1) or resin-based(n = 4) sealant.Only the use of resin-based sealant to obliterate occlusal fissures arrested the progression of non-cavitated occlusal carious lesions in dentin.CONCLUSION: Occlusal fissure sealing with a resin-based sealant may arrest the progression of non-cavitated occlusal dentinal caries.Further clinical trials with longer follow-up times should be performed to increase scientific evidence. | Isauremi Vieira de Assun??o Giovanna de Fátima Alves da Costa Boniek Castillo Dutra Borges | 2014 | World Journal of Clinical Cases2014，2，5： | 3 |
| 10 | Liver fat deposition and mitochondrial dysfunction in morbid obesity:An approach combining metabolomics with liver imaging and histology显示文摘AIM: To explore the usefulness of magnetic resonance imaging(MRI) and spectroscopy(MRS) for assessment of non-alcoholic fat liver disease(NAFLD) as compared with liver histological and metabolomics findings. METHODS: Patients undergoing bariatric surgery following procedures involved in laparoscopic sleeve gastrectomy were recruited as a model of obesityinduced NAFLD in an observational, prospective, singlesite, cross-sectional study with a pre-set duration of 1 year. Relevant data were obtained prospectively and surrogates for inflammation, oxidative stress and lipid and glucose metabolism were obtained through standard laboratory measurements. To provide reliable data from MRI and MRS, novel procedures were designed to limit sampling variability and other sources of error using a 1.5T Signa HDx scanner and protocols acquired from the 3D or 2D Fat SAT FIESTA prescription manager. We used our previously described 1H NMRbased metabolomics assays. Data were obtained immediately before surgery and after a 12-mo period including histology of the liver and measurement of metabolites. Values from 1H NMR spectra obtained after surgery were omitted due to technical limitations.RESULTS: MRI data showed excellent correlation with the concentration of liver triglycerides, other hepatic lipid components and the histological assessment, w h i c h e xc l u d e d t h e p r e s e n c e o f n o n-a l c o h o l i c steatohepatitis(NASH). MRI was sufficient to follow up NAFLD in obese patients undergoing bariatric surgery and data suggest usefulness in other clinical situations. The information provided by MRS replicated that obtained by MRI using the-CH3 peak(0.9 ppm), the-CH2- peak(1.3 ppm, mostly triglyceride) and the-CH=CH- peak(2.2 ppm). No patient depicted NASH. After surgery all patients significantly decreased their body weight and steatosis was virtually absent even in patients with previous severe disease. Improvement was also observed in the serum concentrations of selected variables. The most relevant findings using metabolomics indicate increased levels of triglyceride and monounsaturated fatty acids in severe steatosis but those results were accompanied by a significant depletion of diglycerides, polyunsaturated fatty acids, glucose-6-phosphate and the ATP/AMP ratio. Combined data indicated the coordinated action on mitochondrial fat oxidation and glucose transport activity and may support the consideration of NAFLD as a likely mitochondrial disease. This concept may helpto explain the dissociation between excess lipid storage in adipose tissue and NAFLD and may direct the search for plasma biomarkers and novel therapeutic strategies. A limitation of our study is that data were obtained in a relatively low number of patients.CONCLUSION: MRI is sufficient to stage NAFLD in obese patients and to assess the improvement after bariatric surgery. Other data were superfluous for this purpose. | Nahum Calvo Raúl Beltrán-Debón Esther Rodríguez-Gallego Anna Hernández-Aguilera Maria Guirro Roger Mariné-Casadó Lidón Millá Josep M Alegret Fàtima Sabench Daniel del Castillo María Vinaixa Miguelàngel Rodríguez Xavier Correig Roberto García-álvarez Javier A Menendez Jordi Camps Jorge Joven | 2015 | World Journal of Gastroenterology2015，21，24： | 2 |
| 11 | Adenocarcinoma of the third and fourth portions of the duodenum: The capsule endoscopy value显示文摘Primary adenocarcinoma of the small intestine occurs in over 50% of cases in the duodenum. However,its location in the third and fourth duodenal portions occurs rarely and is a diagnostic challenge. The aim of this work is to report an adenocarcinoma of the third and fourth duodenal portions,emphasizing its diagnostic difficulty and the value of video capsule endoscopy. A man,40 years old,with no medical history,with abdominal discomfort and progressive fatigue,presented four months ago with one episode o f m o d e ra t e m e l e n a. T h e p hy s i c a l e x a m i n a t i o n was normal,except for mucosal pallor. Blood tests were consistent with microcytic,hypochromic iron deficiency anemia with 7.8 g/d L hemoglobin. The upper and lower endoscopy were normal. Additional work-up with video capsule endoscopy showed a polypoid lesion involving the third and fourth portions o f t h e d u o d e n u m. B i o p s y s h o w e d a m o d e ra t e l y differentiated adenocarcinoma. Abdominal computed tomography showed a wall thickening from the third duodenal portion to the proximal jejunum,without distant metastasis. The patient underwent segmental resection(distal duodenum and proximal jejunum) with duodenojejunostomy. The surgical specimen histology confirmed the biopsy diagnosis,with transmural infiltration,without nodal involvement. Conclusion: Adenocarcinoma of the third and fourth portions of the duodenum is difficult to diagnose and capsule endoscopy is of great value. | Feliciano Chanana Paquissi Ana Henriqueta Filipe Bunga Pimentel Lima Maria de Fátima do Nascimento Vieira Lopes Francisco Viamontes Diaz | 2015 | World Journal of Gastroenterology2015，21，31： | 2 |
| 12 | Colorectal cancer diagnosis: Pitfalls and opportunities显示文摘Colorectal cancer(CRC) is a major health problem in the Western world. The diagnostic process is a challenge in all health systems for many reasons: There are often no specific symptoms; lower abdominal symptoms are very common and mostly related to nonneoplastic diseases, not CRC; diagnosis of CRC is mainlybased on colonoscopy, an invasive procedure; and the resource for diagnosis is usually scarce. Furthermore, the available predictive models for CRC are based on the evaluation of symptoms, and their diagnostic accuracy is limited. Moreover, diagnosis is a complex process involving a sequence of events related to the patient, the initial consulting physician and the health system. Understanding this process is the first step in identifying avoidable factors and reducing the effects of diagnostic delay on the prognosis of CRC. In this article, we describe the predictive value of symptoms for CRC detection. We summarize the available evidence concerning the diagnostic process, as well as the factors implicated in its delay and the methods proposed to reduce it. We describe the different prioritization criteria and predictive models for CRC detection, specifically addressing the two-week wait referral guideline from the National Institute of Clinical Excellence in terms of efficacy, efficiency and diagnostic accuracy. Finally, we collected information on the usefulness of biomarkers, specifically the faecal immunochemical test, as non-invasive diagnostic tests for CRC detection in symptomatic patients. | Pablo Vega Fátima Valentín Joaquín Cubiella | 2015 | World Journal of Gastrointestinal Oncology2015，7，12： | 2 |
| 13 | Association of nonalcoholic fatty liver disease and liver cancer显示文摘AIM:To investigate the association between nonalcoholic fatty liver disease(NAFLD) and liver cancer,and NAFLD prevalence in different liver tumors.METHODS:This is a retrospective study of the clinical,laboratory and histological data of 120 patients diagnosed with primary or secondary hepatic neoplasms and treated at a tertiary center where they underwent hepatic resection and/or liver transplantation,with subsequent evaluation of the explant or liver biopsy.The following criteria were used to exclude patients from the study:a history of alcohol abuse,hepatitis B or C infection,no tumor detected in the liver tissue examined by histological analysis,and the presence of chronic autoimmune hepatitis,hemochromatosis,Wilson's disease,or hepatoblastoma.The occurrence of NAFLD and the association with its known risk factors were studied.The risk factors considered were diabetes mellitus,impaired glucose tolerance,impaired fasting glucose,body mass index,dyslipidemia,and arterial hypertension.Presence of reticulin fibers in the hepatic neoplasms was assessed by histological analysis using slide-mounted specimens stained with either hematoxylin and eosin or Masson's trichrome and silver impregnation.Analysis of tumor-free liver parenchyma was carried out to determine the association between NAFLD and its histological grade.RESULTS:No difference was found in the association of NAFLD with the general population(34.2% and 30.0% respectively,95%CI:25.8-43.4).Evaluation by cancer type showed that NAFLD was more prevalent in patients with liver metastasis of colorectal cancer than in patients with hepatocellular carcinoma and intrahepatic cholangiocarcinoma(OR = 3.99,95%CI:1.78-8.94,P < 0.001 vs OR = 0.60,95%CI:0.18-2.01,P = 0.406 and OR = 0.70,95%CI:0.18-2.80,P = 0.613,respectively).There was a higher prevalence of liver fibrosis in patients with hepatocellular carcinoma(OR = 3.50,95%CI:1.06-11.57,P = 0.032).Evaluation of the relationship between the presence of NAFLD,nonalcoholic steatohepatitis,and liver fibrosis,and their risk factors,showed no significant statistical association for any of the tumors studied.CONCLUSION:NAFLD is more common in patients with liver metastases caused by colorectal cancer. | Perla Oliveira Schulz Fabio Goncalves Ferreira Maria de Fátima Araújo Nascimento Andrea Vieira Mauricio Alves Ribeiro André Ibrahim David Luiz Arnaldo Szutan | 2015 | World Journal of Gastroenterology2015，21，3： | 2 |
| 14 | Progress and challenges in the comprehensive management of chronic viral hepatitis: Key ways to achieve the elimination显示文摘Chronic viral hepatitis is a significant health problem throughout the world,which already represents high annual mortality.By 2040,chronic viral hepatitis due to virus B and virus C and their complications cirrhosis and hepatocellular carcinoma will be more deadly than malaria,vitellogenesis-inhibiting hormone,and tuberculosis altogether.In this review,we analyze the global impact of chronic viral hepatitis with a focus on the most vulnerable groups,the goals set by the World Health Organization for the year 2030,and the key points to achieve them,such as timely access to antiviral treatment of direct-acting antiviral,which represents the key to achieving hepatitis C virus elimination.Likewise,we review the strategies to prevent transmission and achieve control of hepatitis B virus.Finally,we address the impact that the coronavirus disease 2019 pandemic has had on implementing elimination strategies and the advantages of implementing telemedicine programs. | Fátima Higuera-de la Tijera Alfredo Servín-Caamaño Luis Servín-Abad | 2021 | World Journal of Gastroenterology2021，27，26： | 2 |
| 15 | Appropriateness of outpatient gastrointestinal endoscopy in a non-academic hospital显示文摘AIM:To assess the appropriate use and the diagnostic yield of upper gastrointestinal endoscopy and colonoscopy in this subgroup of patients.METHODS:In total,789 consecutive outpatients referred for gastrointestinal(GI) endoscopy [381 for esophagogastroduodenoscopy(EGD) and 408 for colonoscopy] were prospectively enrolled in the study.The American Society for Gastrointestinal Endoscopy(ASGE) guidelines were used to assess the relationship between appropriateness and the presence of relevant endoscopic f indings.RESULTS:The overall inappropriate rate was 13.3%.The indications for EGD and colonoscopy were,respectively,appropriate in 82.7% and 82.6% of the exams,uncertain in 5.8% and 2.4% and inappropriate in 11.5% and 15%.The diagnostic yield was signif icant higher forEGDs and colonoscopies judged appropriate and uncertain when compared with those considered inappropriate(EGD:36.6% vs 36.4% vs 11.4%,P = 0.004;Colonoscopy:24.3% vs 20.0% vs 3.3%,P = 0.001).Of the 25 malignant lesions detected,all but one was detected in exams judged appropriate or uncertain.CONCLUSION:This study shows a good adherence to ASGE guidelines by the referring physicians and a significant increase of the diagnostic yield in appropriate examinations,namely in detecting neoplastic lesions.It underscores the importance that the appropriateness of the indication assumes in assuring high-quality GI endoscopic procedures. | Joo Mangualde Marie I Cremers Ana M Vieira Ricardo Freire lia Gamito Cristina Lobato Ana L Alves Fátima Augusto Ana P Oliveira | 2011 | World Journal of Gastrointestinal Endoscopy2011，3，10： | 2 |
| 16 | Dendritic cell deficiencies persist seven months after SARS-CoV-2 infection显示文摘Severe Acute Respiratory Syndrome Coronavirus(SARS-CoV)-2 infection induces an exacerbated inflammation driven by innate immunity components.Dendritic cells(DCs)play a key role in the defense against viral infections,for instance plasmacytoid DCs(pDCs),have the capacity to produce vast amounts of interferon-alpha(IFN-α).In COVID-19 there is a deficit in DC numbers and IFN-αproduction,which has been associated with disease severity.In this work,we described that in addition to the DC deficiency,several DC activation and homing markers were altered in acute COVID-19 patients,which were associated with multiple inflammatory markers.Remarkably,previously hospitalized and nonhospitalized patients remained with decreased numbers of CD1c+myeloid DCs and pDCs seven months after SARS-CoV-2 infection.Moreover,the expression of DC markers such as CD86 and CD4 were only restored in previously nonhospitalized patients,while no restoration of integrinβ7 and indoleamine 2,3-dyoxigenase(IDO)levels were observed.These findings contribute to a better understanding of the immunological sequelae of COVID-19. | Alberto Pérez-Gómez Joana Vitallé Carmen Gasca-Capote Alicia Gutierrez-Valencia María Trujillo-Rodriguez Ana Serna-Gallego Esperanza Muñoz-Muela María de los Reyes Jiménez-Leon Mohamed Rafii-El-Idrissi Benhnia Inmaculada Rivas-Jeremias Cesar Sotomayor Cristina Roca-Oporto Nuria Espinosa Carmen Infante-Domínguez Juan Carlos Crespo-Rivas Alberto Fernández-Villar Alexandre Pérez-González Luis Fernando López-Cortés Eva Poveda Ezequiel Ruiz-Mateos JoséMiguel Cisneros Sonsoles Salto-Alejandre Judith Berastegui-Cabrera Pedro Camacho-Martínez Carmen Infante-Domínguez Marta Carretero-Ledesma Juan Carlos Crespo-Rivas Eduardo Márquez JoséManuel Lomas Claudio Bueno Rosario Amaya JoséAntonio Lepe Jerónimo Pachón Elisa Cordero Javier Sánchez-Céspedes Manuela Aguilar-Guisado Almudena Aguilera Clara Aguilera Teresa Aldabo-Pallas Verónica Alfaro-Lara Cristina Amodeo Javier Ampuero María Dolores Avilés Maribel Asensio Bosco Barón-Franco Lydia Barrera-Pulido Rafael Bellido-Alba Máximo Bernabeu-Wittel Candela Caballero-Eraso Macarena Cabrera Enrique Calderón Jesús Carbajal-Guerrero Manuela Cid-Cumplido Yael Corcia-Palomo Juan Delgado Antonio Domínguez-Petit Alejandro Deniz Reginal Dusseck-Brutus Ana Escoresca-Ortega Fátima Espinosa Nuria Espinosa Michelle Espinoza Carmen Ferrándiz-Millón Marta Ferrer Teresa Ferrer Ignacio Gallego-Texeira Rosa Gámez-Mancera Emilio García Horacio García-Delgado Manuel García-Gutiérrez María Luisa Gascón-Castillo Aurora González-Estrada Demetrio González Carmen Gómez-González Rocío González-León Carmen Grande-Cabrerizo Sonia Gutiérrez Carlos Hernández-Quiles Inmaculada Concepción Herrera-Melero Marta Herrero-Romero Luis Jara Carlos Jiménez-Juan Silvia Jiménez-Jorge Mercedes Jiménez-Sánchez Julia Lanseros-Tenllado Carmina López Isabel López Álvaro López-Barrios Luis F.López-Cortés Rafael Luque-Márquez Daniel Macías-García Guillermo Martín-Gutiérrez Luis Martín-Villén JoséMolina Aurora Morillo María Dolores Navarro-Amuedo Dolores Nieto-Martín Francisco Ortega María Paniagua-García Amelia Peña-Rodríguez Esther Pérez Manuel Poyato Julia Praena-Segovia Rafaela Ríos Cristina Roca-Oporto Jesús F.Rodríguez María Jesús Rodríguez-Hernández Santiago Rodríguez-Suárez Ángel Rodríguez-Villodres Nieves Romero-Rodríguez Ricardo Ruiz Zida Ruiz de Azua Celia Salamanca Sonia Sánchez Víctor Manuel Sánchez-Montagut César Sotomayor Alejandro Suárez Benjumea Javier Toral | 2021 | Cellular & Molecular Immunology2021，18，9： | 2 |
| 17 | Current trends of liver cirrhosis in Mexico: Similitudes and differences with other world regions显示文摘AIM To investigate the main current etiologies of cirrhosis in Mexico.METHODS We performed a cross-sectional retrospective multicenter study that included eight hospitals in different areas of Mexico. These hospitals provide health care to people of diverse social classes. The inclusion criteria were a histological, clinical, biochemical, endoscopic, or imaging diagnosis of liver cirrhosis. Data were obtained during a 5-year period(January 2012-December 2017). RESULTS A total of 1210 patients were included. The mean age was 62.5 years(SD = 12.1), and the percentages of men and women were similar(52.0% vs 48.0%). The most frequent causes of liver cirrhosis were hepatitis C virus(HCV)(36.2%), alcoholic liver disease(ALD)(31.2%), and nonalcoholic steatohepatitis(23.2%), and the least frequent were hepatitis B virus(1.1%), autoimmune disorders(7.3%), and other conditions(1.0%).CONCLUSION HCV and ALD are the most frequent causes of cirrhosis in Mexico. However, we note that non-alcoholic fatty liver disease(NAFLD) as an etiology of cirrhosis increased by 100% compared with the rate noted previously. We conclude that NAFLD will soon become one of the most frequent etiologies of liver cirrhosis in Mexico. | Nahum Méndez-Sánchez Felipe Zamarripa-Dorsey Arturo Panduro Emma Purón-González Edgar Ulises Coronado-Alejandro Carlos Alejandro Cortez-Hernández Fátima Higuera de la Tijera José Luis Pérez-Hernández Eira Cerda-Reyes Heriberto Rodríguez-Hernández Vania César Cruz-Ramón Oscar Lenin Ramírez-Pérez Nancy Edith Aguilar-Olivos Olga Fabiola Rodríguez-Martínez Samantha Cabrera-Palma Guillermo Cabrera-álvarez | 2018 | World Journal of Clinical Cases2018，6，15： | 2 |
