1Impaired T-cell differentiation in diabetic foot ulceration显示文摘Foot ulceration is one of the most debilitating complications associated with diabetes,but its cause remains poorly understood.Several studies have been undertaken to understand healing kinetics or find possible therapies to enhance healing.However,few studies have been directed at understanding the immunological alterations that could influence wound healing in diabetes.In this study,we analysed the T-cell receptor(TCR)repertoire diversity in TCR-αβ^(+)T cells.We also analysed the distribution and phenotype of T cells obtained from the peripheral blood of healthy controls and diabetic individuals with or without foot ulcers.Our results showed that diabetic individuals,especially those with foot ulcers,have a significantly lower naive T-cell number and a poorer TCR-Vβrepertoire diversity.We also showed that the reduced TCR-Vβrepertoire diversity in diabetic individuals was mainly owing to the accumulation of effector T cells,the major source of tumour necrosis factor-αproduction,which was even more pronounced in patients with acute foot ulceration.Moreover,the expression of several inflammatory chemokine receptors was significantly reduced in diabetic patients.In conclusion,effector T-cell accumulation and TCR repertoire diversity reduction appear to precede the development of foot ulcers.This finding may open new immunological therapeutic possibilities and provide a new prognostic tool in diabetic wound care.João Moura João Rodrigues Marta Gonçalves Cláudia Amaral Margarida Lima Eugénia Carvalho 2017Cellular & Molecular Immunology2017,14,9:6
2Metabolic 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 2015World Journal of Gastroenterology2015,21,17:5
3Chronic myeloid leukemia-from the Philadelphia chromosome to specific target drugs:A literature review显示文摘Chronic myeloid leukemia(CML)is a myeloproliferative neoplasm and was the first neoplastic disease associated with a well-defined genotypic anomaly―the presence of the Philadelphia chromosome.The advances in cytogenetic and molecular assays are of great importance to the diagnosis,prognosis,treatment,and monitoring of CML.The discovery of the breakpoint cluster region(BCR)-Abelson murine leukemia(ABL)1 fusion oncogene has revolutionized the treatment of CML patients by allowing the development of targeted drugs that inhibit the tyrosine kinase activity of the BCR-ABL oncoprotein.Tyrosine kinase inhibitors(known as TKIs)are the standard therapy for CML and greatly increase the survival rates,despite adverse effects and the odds of residual disease after discontinuation of treatment.As therapeutic alternatives,the subsequent TKIs lead to faster and deeper molecular remissions;however,with the emergence of resistance to these drugs,immunotherapy appears as an alternative,which may have a cure potential in these patients.Against this background,this article aims at providing an overview on CML clinical management and a summary on the main targeted drugs available in that context.Mariana Miranda Sampaio Maria Luísa Cordeiro Santos Hanna Santos Marques Vinícius Lima de Souza Gonçalves Glauber Rocha Lima Araújo Luana Weber Lopes Jonathan Santos Apolonio Camilo Santana Silva Luana Kauany de SáSantos Beatriz Rocha Cuzzuol Quézia Estéfani Silva Guimarães Mariana Novaes Santos Breno Bittencourt de Brito Filipe Antônio França da Silva Márcio Vasconcelos Oliveira Cláudio Lima Souza Fabrício Freire de Melo 2021World Journal of Clinical Oncology2021,12,2:3
4Dietary approach in the treatment of nonalcoholic fatty liver disease显示文摘Nonalcoholic fatty liver disease(NAFLD) has been identified as one of the most prevalent chronic liver disease in adults and children populations. NAFLD is usually associated with the metabolic syndrome(MS), which is chiefly related to insulin resistance and its consequences. Insulin resistance has a crucial role in the pathogenesis of hepatic steatosis and potentially nonalcoholic steatohepatitis(NASH). Because of the contemporary epidemics of MS and obesity, the burden of NAFLD is also expected to rise. Unhealthy diets, such as the so-called western diet, are enriched in fructose, trans-fatty acids and saturated fat and seem to be associated with the development of NAFLD. In human studies, certain dietary sugars, particularly fructose, are used as a substrate for lipogenesis leading to hepatic fatty infiltration, inflammation, and possibly fibrosis. Other investigations have shown that fat consumption especially cholesterol and trans/saturated fatty acids are also steatogenic and seem to increase visceral adiposity. The identification of specific dietary components that favor the development of NASH could be important for the management of this disorder. This review focuses on the effects of different dietary approaches to prevent and treat NAFLD emphasizing the macronutrients and energy composition.Silvia Marinho Ferolla Luciana Costa Silva Maria de Lourdes Abreu Ferrari Aloísio Sales da Cunha Flaviano dos Santos Martins Cláudia Alves Couto Teresa Cristina Abreu Ferrari 2015World Journal of Hepatology2015,7,24:2
5Identification of patients at-risk for Lynch syndrome in a hospital-based colorectal surgery clinic显示文摘AIM:To determine the prevalence of a family history suggestive of Lynch syndrome (LS) among patients with colorectal cancer (CRC) followed in a coloproctology outpatient clinic in Southern Brazil.METHODS:A consecutive sample of patients with CRC were interviewed regarding personal and family histories of cancer.Clinical data and pathology features of the tumor were obtained from chart review.RESULTS:Of the 212 CRC patients recruited,61 (29%) reported a family history of CRC,45 (21.2%) were diagnosed under age 50 years and 11 (5.2%) had more than one primary CRC.Family histories consistent with Amsterdam and revised Bethesda criteria for LS were identified in 22 (10.4%) and 100 (47.2%) patients,respectively.Twenty percent of the colorectal tumors had features of the high microsatellite instability phenotype,which was associated with younger age at CRC diagnosis and with Bethesda criteria (P < 0.001).Only 5.3% of the patients above age 50 years had been previously submitted for CRC screening and only 4% of patients with suspected LS were referred for genetic risk assessment.CONCLUSION:A significant proportion of patients with CRC were at high risk for LS.Education and training of health care professionals are essential to ensure proper management.Patrícia Koehler-Santos Patricia Izetti Jamile Abud Carlos Eduardo Pitroski Silvia Liliana Cossio Suzi Alves Camey Cláudio Tarta Daniel C Damin Paulo Carvalho Contu Mario Antonello Rosito Patricia Ashton-Prolla Joāo Carlos Prolla 2011World Journal of Gastroenterology2011,17,6:2
6Diabetic neuropathy: An evaluation of the use of quercetin in the cecum of rats显示文摘AIM:To investigate the effect of quercetin supplementation on the myenteric neurons and glia in the cecum of diabetic rats.METHODS:Total preparations of the muscular tunic were prepared from the ceca of twenty-four rats divided into the following groups:control(C),control supplemented with quercetin(200 mg/kg quercetin body weight)(CQ),diabetic(D)and diabetic supplemented with quercetin(DQ).Immunohistochemical double staining technique was performed with HuC/D(general population)/nitric oxide synthase(nNOS),HuC-D/S-100and VIP.Density analysis of the general neuronal population HuC/D-IR,the nNOS-IR(nitrergic subpopulation)and the enteric glial cells(S-100)was performed,and the morphometry and the reduction in varicosity population(VIP-IR)in these populations were analyzed.RESULTS:Diabetes promoted a significant reduction(25%)in the neuronal density of the HuC/D-IR(general population)and the nNOS-IR(nitrergic subpopulation)compared with the C group.Diabetes also significantly increased the areas of neurons,glial cells and VIP-IR varicosities.Supplementation with quercetin in the DQ group prevented neuronal loss in the general population and increased its area(P<0.001)and the area of nitrergic subpopulation(P<0.001),when compared to C group.Quercetin induced a VIP-IR and glial cells areas(P<0.001)in DQ group when compared to C,CQ and D groups.CONCLUSION:In diabetes,quercetin exhibited a neuroprotective effect by maintaining the density of the general neuronal population but did not affect the density of the nNOS subpopulation.Paulo Emilio Botura Ferreira Cláudia Regina Pinheiro Lopes Angela Maria Pereira Alves der Paulo Belato Alves David Robert Linden Jacqueline Nelisis Zanoni Nilza Cristina Buttow 2013World Journal of Gastroenterology2013,19,38:2
