| 1 | Helicobacter pylori infection- recent developments in diagnosis显示文摘Considering the recommended indications for Helicobacter pylori(H.pylori)eradication therapy and the broad spectrum of available diagnostic methods,a reliable diagnosis is mandatory both before and after eradication therapy.Only highly accurate tests should be used in clinical practice,and the sensitivity and specificity of an adequate test should exceed 90%.The choice of tests should take into account clinical circumstances,the likelihood ratio of positive and negative tests,the cost-effectiveness of the testing strategy and the availability of the tests.This review concerns some of the most recent developments in diagnostic methods of H.pylori infection,namely the contribution of novel endoscopic evaluation methodologies for the diagnosis of H.pylori infection,such as magnifying endoscopy techniques and chromoendoscopy.In addition,the diagnostic contribution of histology and the urea breath test was explored recently in specific clinical settings and patient groups.Recent studies recommend enhancing the number of biopsy fragments for the rapid urease test.Bacterial culture from the gastric biopsy is the gold standard technique,and is recommended for antibiotic susceptibility test.Serology is used for initial screening and the stool antigen test is particularly used when the urea breath test is not available,while molecular methods have gained attention mostly for detecting antibiotic resistance. | Ana Isabel Lopes Filipa F Vale Mónica Oleastro | 2014 | World Journal of Gastroenterology2014,20,28: | 12 |
| 2 | 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 |
| 3 | Ophthalmic manifestations in patients with inflammatory bowel disease: a review显示文摘Clinical manifestations of inflammatory bowel disease(IBD) are not locally restricted to the gastrointestinal tract, and a significant portion of patients have involvement of other organs and systems. The visual system is one of the most frequently affected, mainly by inflammatory disorders such as episcleritis, uveitis and scleritis. A critical review of available literature concerning ocular involvement in IBD, as it appears in Pub Med, was performed. Episcleritis, the most common ocular extraintestinal manifestation(EIM), seems to be more associated with IBD activity when compared with other ocular EIMs. In IBD patients, anterior uveitis has an insidious onset, it is longstanding and bilateral, and not related to the intestinal disease activity. Systemic steroids or immunosuppressants may be necessary in severe ocular inflammation cases, and control of the underlying bowel disease is important to prevent recurrence. Our review revealed that ocular involvement is more prevalent in Crohn's disease than ulcerative colitis, in active IBD, mainly in the presence of other EIMs. The ophthalmic symptoms in IBD are mainly nonspecific and their relevance may not be recognized by the clinician; most ophthalmic manifestations are treatable, and resolve without sequel upon prompt treatment. A collaborative clinical care team for management of IBD that includes ophthalmologists is central for improvement of quality care for these patients, and it is also cost-effective. | Leandro Lopes Troncoso Ana Luiza Biancardi Haroldo Vieira de Moraes Jr Cyrla Zaltman | 2017 | World Journal of Gastroenterology2017,23,32: | 7 |

| 5 | 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 |
| 6 | Evaluation of biodegradable electric conductive tube-guides and mesenchymal stem cells显示文摘AIM: To study the therapeutic effect of three tubeguides with electrical conductivity associated to mesenchymal stem cells(MSCs) on neuro-muscular regeneration after neurotmesis.METHODS: Rats with 10-mm gap nerve injury were tested using polyvinyl alcohol(PVA), PVA-carbon nanotubes(CNTs) and MSCs, and PVA-polypyrrole(PPy). The regenerated nerves and tibialis anterior muscles were processed for stereological studies after 20 wk. The functional recovery was assessed serially for gait biomechanical analysis, by extensor postural thrust, sciatic functional index and static sciatic functionalindex(SSI), and by withdrawal reflex latency(WRL). In vitro studies included cytocompatibility, flow cytometry, reverse transcriptase polymerase chain reaction and karyotype analysis of the MSCs. Histopathology of lung, liver, kidneys, and regional lymph nodes ensured the biomaterials biocompatibility. RESULTS: SSI remained negative throughout and independently from treatment. Differences between treted groups in the severity of changes in WRL existed, showing a faster regeneration for PVA-CNTs-MSCs(P < 0.05). At toe-off, less acute ankle joint angles were seen for PVA-CNTs-MSCs group(P = 0.051) suggesting improved ankle muscles function during the push off phase of the gait cycle. In PVA-PPy and PVA-CNTs groups, there was a 25% and 42% increase of average fiber area and a 13% and 21% increase of the 'minimal Feret's diameter' respectively. Stereological analysis disclosed a significantly(P < 0.05) increased myelin thickness(M), ratio myelin thickness/axon diameter(M/d) and ratio axon diameter/fiber diameter(d/D; g-ratio) in PVA-CNT-MSCs group(P < 0.05). CONCLUSION: Results revealed that treatment with MSCs and PVA-CNTs tube-guides induced better nerve fiber regeneration. Functional and kinematics analysis revealed positive synergistic effects brought by MSCs and PVA-CNTs. The PVA-CNTs and PVA-PPy are promising scaffolds with electric conductive properties, bio- and cytocompatible that might prevent the secondary neurogenic muscular atrophy by improving the reestablishment of the neuro-muscular junction. | Jorge Ribeiro Tiago Pereira Ana Rita Caseiro Paulo Armada-da-Silva Isabel Pires Justina Prada Irina Amorim Sandra Amado Miguel Franca Carolina Goncalves Maria Ascensao Lopes Jose Domingos Santos Dina Morais Silva Stefano Geuna Ana Lúcia Luís Ana Colette Maurício | 2015 | World Journal of Stem Cells2015,7,6: | 2 |
| 7 | Multi-target prediction of wheat flour quality parameters with near infrared spectroscopy显示文摘Near Infrared(NIR)spectroscopy is an analytical technology widely used for the nondestructive characterisation of organic samples,considering both qualitative and quantitative attributes.In the present study,the combination of Multi-target(MT)prediction approaches and Machine Learning algorithms has been evaluated as an effective strategy to improve prediction performances of NIR data from wheat flour samples.Three different Multi-target approaches have been tested:Multi-target Regressor Stacking(MTRS),Ensemble of Regressor Chains(ERC)and Deep Structure for Tracking Asynchronous Regressor Stack(DSTARS).Each one of these techniques has been tested with different regression methods:Support Vector Machine(SVM),Random Forest(RF)and Linear Regression(LR),on a dataset composed of NIR spectra of bread wheat flours for the prediction of qualityrelated parameters.By combining all MT techniques and predictors,we obtained an improvement up to 7%in predictive performance,compared with the corresponding Single-target(ST)approaches.The results support the potential advantage of MT techniques over ST techniques for analysing NIR spectra. | Sylvio Barbon Junior Saulo Martielo Mastelini Ana Paula ACBarbon Douglas Fernandes Barbin Rosalba Calvini Jessica Fernandes Lopes Alessandro Ulrici | 2020 | Information Processing in Agriculture2020,7,2: | 2 |
| 8 | 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 |

| 12 | 经皮的内视镜的 gastrostomy 的稀罕复杂并发症: 食道的癌的 Ostomy 转移显示文摘 The authors present the case of a 55-year-old male with a stage Ⅲ(T4N1M0) squamous-cell esophageal carcinoma, who underwent percutaneous endoscopic gastrostomy(PEG). The pull method of tube placement was used. Five months after the procedure, the patient was referred to the hospital with a hard palpable tumour at the ostomy site. The hystologic exam revealed an abdominal wall metastasis of the esophageal cancer. The authors present this case because of the rarity of metastasis in ostomy after placement of PEG in patients with tumours located in the head and neck. In this particular context and judging by the rarity of situation, the clinical impact of this phenomenom is limited. Nevertheless, metastasis in ostomy site could be prevented by the push method, laparoscopy or laparotomy. | Ana Lúcia Sousa Diamantino Sousa Francisco Velasco Francisco Aucena Ana Lopes Horácio Guerreiro | 2013 | World Journal of Gastrointestinal Oncology2013,5,11: | 1 |
