| 1 | 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 |
| 2 | 低渗核黄素在圆锥角膜患者角膜交联术中的应用(英文)显示文摘目的:比较圆锥角膜患者角膜交联(CXL)、等渗(IR)和低渗核黄素(HR)的结果。方法:回顾性研究,包括29例29眼圆锥角膜患者行角膜交联术,IR组15眼,HR组14眼。参数分析包括(随访1a):最佳矫正视力(BCVA),球体和柱体,中央和较薄处角膜厚度,平均和最大角膜曲率(分别为Km和Kmax),并发症及进展。结果:观察到两组的BCVA提高:治疗前IR组为0.26±0.57,HR组为0.47±0.72。术后1a,IR组为0.13±0.79,HR组为0.29±1.52,IR组BCVA更高(P=0.018)。术后1mo,两组中央角膜厚度(μm)均减少,但在接下来的数月中增加:术前IR组为497±28μm,HR组为432±14μm;术后1a,IR组为480±31μm,HR组为424±15μm。较薄处角膜厚度也是如此,术前IR组为487±29μm,HR组为410±20μm;术后1a,IR组为468±33μm,HR组为413±13μm。两组中Km和Kmax均降低。每组6眼呈现短暂的混浊,无持续性混浊。结论:在中央角膜厚度<400μm的患者中,HR的使用似乎是一个有效的替代执行传统CXL的技术。 | Ana Sofia Lopes Diana Silva Susana Henriques Peter Pego Cristina Vendrell Isabel Prieto | 2020 | 国际眼科杂志2020，20，2： | 2 |

| 5 | Fecal marker levels as predictors of need for endoscopic balloon dilation in Crohn's disease patients with anastomotic strictures显示文摘AIM To evaluate the accuracy and best cut-off value of fecal calprotectin(FC) and fecal lactoferrin(FL) to predict disease recurrence in asymptomatic patients presenting with anastomotic strictures. METHODS This was a longitudinal single tertiary center study based on prospectively collected data(recorded in a clinical database created for this purpose) performed between March 2010 and November 2014. Crohn's disease(CD) patients with anastomotic stricture who submitted to postoperative endoscopic evaluation were included. Stools were collected on the day before bowel cleaning for FC and FL. Endoscopic balloon dilation(EBD) was performed if the patient presented an anastomotic stricture not traversed by the colonoscope, regardless of patients' symptoms. Successful dilation was defined as passage of the colonoscope through the dilated stricture into the neotermimal ileum.Postoperative recurrence was defined as a modified Rutgeerts score of ≥ i2 b. RESULTS In a total of 178 patients who underwent colonoscopy, 58 presented an anastomotic stricture, 86% were asymptomatic, and 48(54% male; median age of 46.5 years) were successfully dilated. Immediate success rate was 92% and no complications were recorded. FC and FL levels correlated significantly with endoscopic recurrence(P < 0.001) with an optimal cut-off value of 90.85 μg/g(sensitivity of 95.5%, specificity of 69.2%, positive predictive value(PPV) of 72.4%, negative predictive value(NPV) of 94.7% and accuracy of 81%] for FC and of 5.6 μg/g(sensitivity of 77.3%, specificity of 69.2%, PPV of 68%, NPV of 78.4% and accuracy of 72.9%) for FL.CONCLUSION Fecal markers are good predictors of CD endoscopic recurrence in patients with asymptomatic anastomotic stricture. FC and FL may guide the need for EBD in this context. | Susana Lopes Patrícia Andrade Eduardo Rodrigues-Pinto Joana Afonso Guilherme Macedo Fernando Magro | 2017 | World Journal of Gastroenterology2017，23，35： | 1 |

| 8 | Capsule enteroscopy is useful for the therapeutic management of Crohn's disease显示文摘AIM: To analyze therapeutic changes in Crohn's disease(CD) patients following video capsule endoscopy(VCE) and to assess the usefulness of Lewis score and the Patency Capsule.METHODS: Patency Capsule was performed in every patient that had indication for VCE, and those with negative patency did not undergo VCE. Patients with established CD that underwent VCE between January 2011 and February 2014 were selected for this study; those with suspected CD were excluded, independent of VCE results, since our purpose was to address differences in therapeutic regimen in CD patients before and after VCE. Patients with inconclusive VCE were also excluded. Patients had to be free of non-steroidal anti-inflammatories for at least 1 mo. Those patients who met these criteria were allocated into one of three groups: Staging group(asymptomatic CD patients that underwent VCE for staging of CD), Flare group(patients with active CD), or Post-op group(CD patients evaluated for post-operative recurrence). Lewis score was calculated for every VCE procedure. Statisticalanalysis was performed to address the impact of VCE findings on the therapeutic management of CD patients and to evaluate the utility of the Lewis score.RESULTS: From a total of 542 VCEs, 135 were performed in patients with CD. Patency capsule excluded nearly 25% of the patients who were supposed to undergo VCE. No videocapsule retention during VCE was reported. From these 135 patients, 29 were excluded because CD diagnosis was not established at the time of VCE. Therefore, a total of 106 patients were included in the final analysis. From these, the majority were in the Staging group(n = 73, 69%), and the remaining were in the Flare(n = 23, 22%) or Post-op(n = 10, 9%) group. Median time between diagnosis and VCE was 5.5 years. Overall, VCE determined changes in the treatment of 40% of patients: only 21% remained free of immunosuppressors after VCE compared to 44% before VCE(P < 0.001). The differences in therapy before and after VCE achieved statistical significance in the Staging and Flare groups. In addition, patients were significantly different when stratified regarding time since diagnosis to the date of VCE. A higher Lewis score was associated with therapeutic modifications(P < 0.0001); where a score higher than 1354 was related to 90% probability of changing therapy [area under the receiver operative characteristic(AUROC) 0.80(95%CI: 0.69-0.88)]. CONCLUSION: VCE significantly changed the therapeutic management of CD patients, even in those with long-term disease. Systematic use of Patency capsule allowed for no videocapsule retention. | Joao Santos-Antunes Hélder Cardoso Susana Lopes Margarida Marques Amadeu CR Nunes Guilherme Macedo | 2015 | World Journal of Gastroenterology2015，21，44： | 1 |

| 10 | Burden and factors associated with schistosomiasis and soil-transmitted helminth infections among school-age children in Huambo,Uige and Zaire provinces,Angola显示文摘Background:Schistosomiasis and soil-transmitted helminths(STHs)contribute high disease burdens amongst the neglected tropical diseases(NTDs)and are public health problems in Angola.This study reports the prevalence,intensity and risk factors for schistosomiasis and STH infection in Huambo,Uige and Zaire provinces,Angola,to inform a school-based preventive chemotherapy program.Methods:A two-stage cluster design was used to select schools and schoolchildren to participate in parasitological and water,sanitation and hygiene(WASH)surveys across Huambo,Uige,and Zaire provinces.Point-of-care circulating cathodic antigen and urinalysis rapid diagnostic tests(RDTs)were used to determine the prevalence of Schistosoma mansoni and S.haematobium,respectively.Kato-Katz was used to identify and quantify STH species and quantify and compare with RDTs for S.mansoni.Urine filtration was used to quantify and compare with RDTs for S.haematobium.Descriptive statistics were used for prevalence and infection intensity of schistosomiasis and STH infection.Performance of RDTs was assessed through specificity and Cohen’s Kappa agreement with microscopy.A multivariate regression analysis was used to determine demographic and WASH factors associated with schistosomiasis and STH infection.Results:A total 575 schools and 17,093 schoolchildren participated in the schistosomiasis survey,of which 121 schools and 3649 schoolchildren participated in the STH survey.Overall prevalence of S.mansoni was 21.2%(municipality range 0.9–74.8%)and S.haematobium 13.6%(range 0–31.2%),with an overall prevalence of schistosomiasis of 31.4%(range 5.9–77.3%).Overall prevalence of Ascaris lumbricoides was 25.1%(range 0–89.7%),hookworm 5.2%(range 0–42.6%),and Trichuris trichiura 3.6%(range 0–24.2%),with an overall prevalence of STH infection of 29.5%(range 0.8–89.7%).Ecological zone and ethnicity were factors associated with schistosomiasis and STH infection,with older age and female sex additional risk factors for S.haematobium.Conclusions:Most municipalities met World Health Organization defined prevalence thresholds for a schistosomiasis preventive chemotherapy program.A STH preventive chemotherapy program is indicated for nearly all municipalities in Uige and select municipalities in Huambo and Zaire.The association between ecological zone and ethnicity with schistosomiasis and STH infection necessitates further evaluation of home and school environmental,sociodemographic and behavioural factors to inform targeted control strategies to complement preventive chemotherapy programs. | Adam W.Bartlett Jose C.Sousa-Figueiredo Roelofje Cvan Goor Paul Monaghan Warren Lancaster Rukaaka Mugizi Elsa P.Mendes Susana Vaz Nery Sergio Lopes | 2022 | Infectious Diseases of Poverty2022，11，3： | 0 |
| 11 | Exosomal glypican-1 is elevated in pancreatic cancer precursors and can signal genetic predisposition in the absence of endoscopic ultrasound abnormalities显示文摘BACKGROUND Individuals within specific risk groups for pancreatic ductal adenocarcinoma(PDAC)[mucinous cystic lesions(MCLs),hereditary risk(HR),and new-late onset diabetes mellitus(NLOD)]represent an opportunity for early cancer detection.Endoscopic ultrasound(EUS)is a premium image modality for PDAC screening and precursor lesion characterization.While no specific biomarker is currently clinically available for this purpose,glypican-1(GPC1)is overexpressed in the circulating exosomes(crExos)of patients with PDAC compared with healthy subjects or those harboring benign pancreatic diseases.AIM To evaluate the capacity of GPC1+crExos to identify individuals at higher risk within these specific groups,all characterized by EUS.METHODS This cross-sectional study with a prospective unicentric cohort included 88 subjects:40 patients with MCL,20 individuals with HR,and 20 patients with NLOD.A control group(CG)was submitted to EUS for other reasons than pancreatic pathology,with normal pancreas and absence of hereditary risk factors(n=8).The inclusion period was between October 2016 and January 2019,and the study was approved by the Ethics Committee of Centro Hospitalar Universitário de São João,Porto,Portugal.All patients provided written informed consent.EUS and blood tests for quantification of GPC1+crExos by flow cytometry and carbohydrate antigen 19-9(CA 19-9)levels by ELISA were performed in all subjects.EUS-guided tissue acquisition was done whenever necessary.For statistical analysis,SPSS®27.0(IBM Corp.,Armonk,NY,United States)version was used.All graphs were created using GraphPad Prism 7.00(GraphPad Software,San Diego,CA,United States).RESULTS Half of MCLs harbored worrisome features(WF)or high-risk stigmata(HRS).Pancreatic abnormalities were detected by EUS in 10.0%and 35.0%in HR and NLOD individuals,respectively,all considered non-malignant and“harmless.”Median levels of GPC1+crExos were statistically different:MCL[99.4%,interquartile range(IQR):94.9%-99.8%],HR(82.0%,IQR:28.9%-98.2%),NLOD(12.6%,IQR:5.2%-63.4%),and CG(16.2%,IQR:6.6%-20.1%)(P<0.0001).Median levels of CA 19-9 were within the normal range in all groups(standard clinical cut-off of 37 U/mL).Within HR,individuals with a positive history of cancer had higher median levels of GPC1+crExos(97.9%;IQR:61.7%-99.5%),compared to those without(59.7%;IQR:26.3%-96.4%),despite no statistical significance(P=0.21).Pancreatic cysts with WF/HRS were statistically associated with higher median levels of GPC1+crExos(99.6%;IQR:97.6%-99.8%)compared to those without(96.5%;IQR:81.3%-99.5%)(P=0.011),presenting an area under the receiver operating characteristic curve value of 0.723(sensitivity 75.0%and specificity 67.7%,using a cutoff of 98.5%;P=0.012).CONCLUSION GPC1+crExos may act as biomarker to support the diagnosis and stratification of PDAC precursor lesions,and in signaling individuals with genetic predisposition in the absence of EUS abnormalities. | Pedro Moutinho-Ribeiro Ines A Batista Sofia T Quintas Bárbara Adem Marco Silva Rui Morais Armando Peixoto Rosa Coelho Pedro Costa-Moreira Renato Medas Susana Lopes Filipe Vilas-Boas Manuela Baptista Diogo Dias-Silva Ana L Esteves Filipa Martins Joanne Lopes Helena Barroca Fátima Carneiro Guilherme Macedo Sonia A Melo | 2022 | World Journal of Gastroenterology2022，28，31： | 0 |

| 13 | Endoscopic balloon dilation of crohn's disease stricturessafety,efficacy and clinical impact显示文摘AIM To evaluate the incidence of anastomotic strictures after intestinal resection in Crohn's disease(CD), demonstrate long-term efficacy and safety of endoscopic balloon dilation(EBD) in CD strictures and its impact on the diagnosis of subclinical postoperative endoscopic recurrence. METHODS Retrospective single tertiary center study based on prospectively collected data between 2010 and 2015including anastomotic and non-anastomotic strictures. RESULTS29% of 162 CD patients included developed an anastomotic stricture. 43 patients with anastomotic strictures and 37 with non-anastomotic strictures underwent EBD; technical success was 97.7% and 100%, respectively, however, 63% and 41% needed repeat dilation during the 4.4-year follow-up. Longer periods between surgery and index colonoscopy and higher lactoferrin levels were associated with the presence of stricture after surgery. Calprotectin levels > 83.35 μg/g and current or past history of smoking were associated with a shorter time until need for dilation(HR = 3.877, 95%CI: 1.480-10.152 and HR = 3.041, 95%CI: 1.213-7.627). Anastomotic strictures had a greater need for repeat dilation(63% vs 41%, P = 0.047). No differences were found between asymptomatic and symptomatic cohorts. Disease recurrence diagnosis was only possible after EBD in a third of patients. CONCLUSION EBD is an effective and safe alternative to surgery, with a good short and long-term outcome, postponing or even avoiding further surgery. EBD may allow to diagnose disease recurrence in patients with no clinical signs/biomarkers of disease activity. | Susana Lopes Eduardo Rodrigues-Pinto Patrícia Andrade Joana Afonso Todd H Baron Fernando Magro Guilherme Macedo | 2017 | World Journal of Gastroenterology2017，23，41： | 0 |
| 14 | Effects of exercise-based cardiac rehabilitation on inflammatory biomarkers in patients with cardiovascular disease:a systematic review with meta-analysis显示文摘Background:Evidence supports the anti-inflammatory effect of exercise-based cardiac rehabilitation(CR)in patients with cardiovascular disease(CVD).Nonetheless,the influence of training variables on the effects of exercise training is debateable.Therefore,this systematic review with meta-analysis aims to i)estimate the effects of exercise-based CR on the circulating levels of inflammatory biomarkers in patients with CVD based on the type of exercise,and ii)analyse the influence of other potential moderator variables.Methods:Electronic searches were performed in PubMed,Scopus,and Web of Science databases up to October 2022.A random-effects models of standardised mean difference(SMD)were used.Subgroup analyses and meta-regressions were used to carry out heterogeneity analyses.Results:Aerobic exercise diminished the levels of C-reactive protein compared with the control group in patients with CVD(SMD+=-0.33[95%CI=-0.47,-0.20),as well as the levels of tumor necrosis factor-alfa exclusively in patients with chronic heart failure(SMD+=-0.38[95%CI=-0.59,-0.17]).Moreover,heterogeneity analyses showed that the effect of aerobic exercise on vascular cell adhesion molecule-1 is higher in studies that carried out a CR programme based exclusively on exercise,as well as in studies that performed a shorter intervention period or carried out a lower number of exercise sessions(P≤0.05).Conclusion:Our findings support the anti-inflammatory effect of aerobic exercise in patients with CVD.The low number of studies testing interventions using resistance or combined exercise precludes a definitive answer about their anti-inflammatory effects in this patient population. | Agustin Manresa-Rocamora Susana Lopes Ana Fernandez Joana Martins Vicente Climent-Paya Jose Manuel Sarabia Fernando Ribeiro | 2022 | TMR Non-Drug Therapy2022，5，4： | 0 |
