| 1 | Using old liver grafts for liver transplantation: Where are the limits?显示文摘The scarcity of ideal liver grafts for orthotopic liver transplantation(OLT) has led transplant teams to investigate other sources of grafts in order to augment the donor liver pool. One way to get more liver grafts is to use marginal donors, a not well-defined group which includes mainly donors > 60 years, donors with hypernatremia or macrosteatosis > 30%, donors with hepatitis C virus or hepatitis B virus positive serologies, cold ischemia time > 12 h, non-heart-beating donors, and grafts from split-livers or living-related donations. Perhaps the most practical and frequent measure to increase the liver pool, and thus to reduce waiting list mortality, is to use older livers. In the past years the results of OLT with old livers have improved, mainly due to better selection and maintenance of donors, improvements in surgical techniques in donors and recipients, and intra- and post-OLT management. At the present time, sexagenarian livers are generally accepted, but there still exists some controversy regarding the use of septuagenarian and octogenarian liver grafts. The aim of this paper is to briefly review the aging process of the liver and reported experiences using old livers for OLT. Fundamentally, the series of septuagenarian and octogenarian livers will be addressed to see if there is a limit to using these aged grafts. | Carlos Jiménez-Romero Oscar Caso Maestro Félix Cambra Molero Iago Justo Alonso Cristina Alegre Torrado Alejandro Manrique Municio Jorge Calvo Pulido Carmelo Loinaz Segurola Enrique Moreno González | 2014 | World Journal of Gastroenterology2014，20，31： | 11 |
| 2 | Phase angle obtained by bioelectrical impedance analysis independently predicts mortality in patients with cirrhosis显示文摘AIM To evaluate the prognostic value of the phase angle(PA)obtained from bioelectrical impedance analysis(BIA) for mortality prediction in patients with cirrhosis. METHODS In total, 134 male cirrhotic patients prospectively completed clinical evaluations and nutritional assessment by BIA to obtain PAs during a 36-mo follow-up period. Mortality risk was analyzed by applying the PA cutoff point recently proposed as a malnutrition marker(PA ≤ 4.9°) in Kaplan-Meier curves and multivariate Cox regression models. RESULTS The patients were divided into two groups according to the PA cutoff value(PA > 4.9°, n = 73; PA ≤ 4.9°, n = 61). Weight, height, and body mass index were similar in both groups, but patients with PAs > 4.9° were younger and had higher mid-arm muscle circumference, albumin, and handgrip-strength values and lower severe ascites and encephalopathy incidences, interleukin(IL)-6/IL-10 ratios and C-reactive protein levels than did patients with PAs ≤ 4.9°(P ≤ 0.05). Forty-eight(35.80%) patients died due to cirrhosis, with a median of 18 mo(interquartile range, 3.3-25.6 mo) follow-up until death. Thirty-one(64.60%) of these patients were from the PA ≤ 4.9° group. PA ≤ 4.9° significantly and independently affected the mortality model adjusted for Model for End-Stage Liver Disease score and age(hazard ratio = 2.05, 95%CI: 1.11-3.77, P = 0.021). In addition, Kaplan-Meier curves showed that patients with PAs ≤ 4.9° were significantly more likely to die. CONCLUSION In male patients with cirrhosis, the PA ≤ 4.9° cutoff was associated independently with mortality and identified patients with worse metabolic, nutritional, and disease progression profiles. The PA may be a useful and reliable bedside tool to evaluate prognosis in cirrhosis. | Giliane Belarmino Maria Cristina Gonzalez Raquel S Torrinhas Priscila Sala Wellington Andraus Luiz Augusto Carneiro D'Albuquerque Rosa Maria R Pereira Valéria F Caparbo Graziela R Ravacci Lucas Damiani Steven B Heymsfield Dan L Waitzberg | 2017 | World Journal of Hepatology2017，9，7： | 11 |
| 3 | 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 |
| 4 | Quality of life, work productivity impairment and healthcare resources in inflammatory bowel diseases in Brazil显示文摘BACKGROUND Inflammatory bowel diseases(IBD)have been associated with a low quality of life(QoL)and a negative impact on work productivity compared to the general population.Information about disease control,patient-reported outcomes(PROs),treatment patterns and use of healthcare resources is relevant to optimizing IBD management.AIM To describe QoL and work productivity and activity impairment(WPAI),treatment patterns and use of healthcare resources among IBD patients in Brazil.METHODS A multicenter cross-sectional study included adult outpatients who were previously diagnosed with moderate to severe Crohn’s disease(CD)or ulcerative colitis(UC).At enrolment,active CD and UC were defined as having a Harvey Bradshaw Index≥8 or a CD Activity Index≥220 or calprotectin>200μg/g or previous colonoscopy results suggestive of inadequate control(per investigator criteria)and a 9-point partial Mayo score≥5,respectively.The PRO assessment included the QoL questionnaires SF-36 and EQ-5D-5L,the Inflammatory Bowel Disease Questionnaire(IBDQ),and the WPAI questionnaire.Information about healthcare resources and treatment during the previous 3 years was collected from medical records.Chi-square,Fisher’s exact and Student’s t-/Mann-Whitney U tests were used to compare PROs,treatment patterns and the use of healthcare resources by disease activity(α=0.05).RESULTS Of the 407 patients in this study(CD/UC:64.9%/35.1%,mean age 42.9/45.9 years,54.2%/56.6%female,38.3%/37.1%employed),44.7%/25.2%presented moderate-to-severe CD/UC activity,respectively,at baseline.Expressed in median values for CD/UC,respectively,the SF-36 physical component was 46.6/44.7 and the mental component was 45.2/44.2,the EQ-visual analog scale score was 80.0/70.0,and the IBDQ overall score was 164.0/165.0.Moderate to severe activity,female gender,being unemployed,a lower educational level and lower income were associated with lower QoL(P<0.05).Median work productivity impairment was 20%and 5%for CD and UC patients,respectively,and activity impairment was 30%,the latter being higher among patients with moderate to severe disease activity compared to patients with mild or no disease activity(75.0%vs 10.0%,P<0.001).For CD/UC patients,respectively,25.4%/2.8%had at least one surgery,38.3%/19.6%were hospitalized,and 70.7%/77.6%changed IBD treatment at least once during the last 3 years.The most common treatments at baseline were biologics(75.3%)and immunosuppressants(70.9%)for CD patients and 5-ASA compounds(77.5%)for UC patients.CONCLUSION Moderate to severe IBD activity,especially among CD patients,is associated with a substantial impact on QoL,work productivity impairment and an increased number of IBD surgeries and hospitalizations in Brazil. | Rogerio Serafim Parra Julio MF Chebli Heda MBS Amarante Cristina Flores Jose ML Parente Odery Ramos Milene Fernandes Jose JR Rocha Marley R Feitosa Omar Feres Antonio S Scotton Rodrigo B Nones Murilo M Lima Cyrla Zaltman Carolina D Goncalves Isabella M Guimaraes Genoile O Santana Ligia Y Sassaki Rogerio S Hossne Mauro Bafutto Roberto LK Junior Mikaell AG Faria Sender J Miszputen Tarcia NF Gomes Wilson R Catapani Anderson A Faria Stella CS Souza Rosana F Caratin Juliana T Senra Maria LA Ferrari | 2019 | World Journal of Gastroenterology2019，25，38： | 2 |

| 7 | 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 |
| 8 | 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 |
