| 1 | Cytokines,cytokine gene polymorphisms and Helicobacter pylori infection:Friend or foe?显示文摘Helicobacter pylori(H.pylori)is a flagellated,spiralshaped,microaerophilic Gram-negative bacillus that colonises the gastric mucosa of more than 50%of the human population.Infection is a risk factor for gastritis,ulcer disease and stomach cancer.Immunity against H.pylori is mainly related to Th1/Th17 skewing,and the activation of regulatory T cells is the main strategy used to limit inflammatory responses,which can result in the pathogen persistence and can lead to chronic gastrointestinal diseases,including cancer.Furthermore,host genetic factors that affect cytokines may determine differences in the susceptibility to many diseases.In this review,we present the cytokine profiles and the main cytokine gene polymorphisms associated with resistance/susceptibility to H.pylori and discuss how such polymorphisms may influence infection/disease outcomes. | Camila A Figueiredo Cintia Rodrigues Marques Ryan dos Santos Costa Hugo Bernardino F da Silva Neuza M Alcantara-Neves | 2014 | World Journal of Gastroenterology2014,20,18: | 11 |
| 2 | Use of butyrate or glutamine in enema solution reduces inflammation and fibrosis in experimental diversion colitis显示文摘AIM:To investigate whether butyrate or glutamine enemas could diminish inflammation in experimental diversion colitis.METHODS:Wistar specific pathogen-free rats were submitted to a Hartmann's end colostomy and treated with enemas containing glutamine,butyrate,or saline.Enemas were administered twice a week in the excluded segment of the colon from 4 to 12 wk after the surgical procedure.Follow-up colonoscopy was performed every 4 wk for 12 wk.The effect of treatment was evaluated using video-endoscopic and histologic scores and measuring interleukin-1β,tumor necrosis factor-alpha,and transforming growth factor beta production in organ cultures by enzyme linked immunosorbent assay.RESULTS:Colonoscopies of the diverted segment showed mucosa with hyperemia,increased number of vessels,bleeding and mucus discharge.Treatment with either glutamine or butyrate induced significant reductions in both colonoscopic(P < 0.02) and histological scores(P < 0.01) and restored the densities of collagen fibers in tissue(P = 0.015;P = 0.001),the number of goblet cells(P = 0.021;P = 0.029),and the rate of apoptosis within the epithelium(P = 0.043;P = 0.011) to normal values.The high levels of cytokines in colon explants from rats with diversion colitis significantly decreased to normal values after treatment with butyrate or glutamine.CONCLUSION:The improvement of experimental diversion colitis following glutamine or butyrate enemas highlights the importance of specific luminal nutrients in the homeostasis of the colonic mucosa and supports their utilization for the treatment of human diversion colitis. | Rodrigo Goulart Pacheco Christiano Costa Esposito Lucas CM Müller Morgana TL Castelo-Branco Leonardo Pereira Quintella Vera Lucia A Chagas Heitor Siffert P de Souza Alberto Schanaider | 2012 | World Journal of Gastroenterology2012,18,32: | 9 |
| 3 | Helical tomotherapy and volumetric modulated arc therapy:New therapeutic arms in the breast cancer radiotherapy显示文摘AIM To analyse clinical and dosimetric results of helical tomotherapy(HT) and volumetric modulated arc therapy(VMAT) in complex adjuvant breast and nodes irradiation.METHODS Seventy-three patients were included(31 HT and 42 VMAT). Dose were 63.8 Gy(HT) and 63.2 Gy(VMAT) in the tumour bed, 52.2 Gy in the breast, 50.4 Gy in supraclavicular nodes(SCN) and internal mammary chain(IMC) with HT and 52.2 Gy and 49.3 Gy in IMC and SCN with VMAT in 29 fractions. Margins to particle tracking velocimetry were greater in the VMAT cohort(7 mm vs 5 mm).RESULTS For the HT cohort, the coverage of clinical target volumes was as follows: Tumour bed: 99.4% ± 2.4%; breast: 98.4% ± 4.3%; SCN: 99.5% ± 1.2%; IMC:96.5% ± 13.9%. For the VMAT cohort, the coverage was as follows: Tumour bed: 99.7% ± 0.5%, breast: 99.3% ± 0.7%; SCN: 99.6% ± 1.4%; IMC: 99.3% ± 3%. For ipsilateral lung, Dmean and V20 were 13.6 ± 1.2 Gy, 21.1% ± 5%(HT) and 13.6 ± 1.4 Gy, 20.1% ± 3.2%(VMAT). Dmean and V30 of the heart were 7.4 ± 1.4 Gy, 1% ± 1%(HT) and 10.3 ± 4.2 Gy, 2.5% ± 3.9%(VMAT). For controlateral breast Dmean was 3.6 ± 0.2 Gy(HT) and 4.6 ± 0.9 Gy(VMAT). Acute skin toxicity grade 3 was 5% in the two cohorts.CONCLUSION HT and VMAT in complex adjuvant breast irradiation allow a good coverage of target volumes with an acceptable acute tolerance. A longer follow-up is needed to assess the impact of low doses to healthy tissues. | Olivier Lauche Youlia M Kirova Pascal Fenoglietto Emilie Costa Claire Lemanski Celine Bourgier Olivier Riou David Tiberi Francois Campana Alain Fourquet David Azria | 2016 | World Journal of Radiology2016,8,8: | 7 |

| 5 | Inflammatory bowel disease in an underdeveloped region of Northeastern Brazil显示文摘AIM: To evaluate the demographic characteristics and clinical phenotypes of inflammatory bowel disease(IBD) in a geographic area in Northeastern Brazil.METHODS: This retrospective study was conducted at the Hospital of the Federal University of Piauí in Northeastern Brazil. Demographic characteristics and clinical phenotypes of IBD were analyzed in relation to the time of diagnostic confirmation, which was defined as the date of disease onset. Data were collected between January 2011 and December 2012 and included all census patients 18 years of age or older during that period for whom there was diagnostic confirmation of Crohn's disease(CD), ulcerative colitis(UC), or unclassified colitis according to the Montreal criteria. We also analyzed the period of time between the onset of clinical manifestations and the diagnosis of IBD(delay in the diagnosis). Statistical analyses included means and standard deviations for numeric variables and the Pearson χ2 adherence test for nominal variables. The annual index occurrence and overall prevalence of IBD at our institution were also calculated, with P values < 0.05 indicating statistical significance. This study was approved by the Institutional Ethics and Research Committee.RESULTS: A total of 252 patients with IBD were included, including 152(60.3%) UC patients and 100(39.7%) CD patients. The clinical and demographic characteristics of all patients with IBD showed a female to male ratio of 1.3:1.0 and a mean age of35.2(SD = 14.5) years. In addition, the majority of patients were miscegenated(171, 67.9%), had received higher education(157, 62.4%), lived in urban areas(217, 86.1%), and were under the age of 40 years(97, 62.5%). For patients with CD, according to the Montreal classification, the predominant features present from the onset of disease were an age between 17 and 40 years(A2); colonic disease location(L2); and nonstricturing, nonfistulizing disease behavior(B1). However, approximately one-quarter of all CD patients demonstrated perineal involvement. We also observed considerable delay in the diagnosis of IBD throughout the entire study period(mean = 35.5 mo). In addition, the annual index occurrence rose from 0.08 to 1.53 cases/105 inhabitants/year during the study period, and the prevalence rate was 12.8 cases/105 inhabitants in 2012. Over the last two decades, there was a noted increase in the frequency of IBD in the study area.CONCLUSION: In this study, there was a predominance of patients with UC, young people under 40 years of age, individuals with racial miscegenation, and low annual incomes. | José Miguel Luz Parente Claudio Saddy Rodrigues Coy Viriato Campelo Mírian Perpétua Palha Dias Parente Leonardo Araújo Costa Renata Mendes da Silva Celso Stephan José Murilo Robilotta Zeitune | 2015 | World Journal of Gastroenterology2015,21,4: | 3 |
| 6 | Association between EGF +61A/G polymorphism and gastric cancer in Caucasians显示文摘AIM: To investigate the association between epidermal growth factor (EGF) +61A/G polymorphism and susceptibility to gastric cancer, through a cross-sectional study. METHODS: Polymerase chain reaction resctriction fragment lenght polymorphism analyses were used to genotype EGF +61 in 207 patients with gastric lesions (162 patients with gastric adenocarcinomas, 45 with atrophy or intestinal metaplasia) and 984 controls. All subjects were Caucasian. RESULTS: Genotype distribution was 23.5% for GG and 76.5% for GA/AA in the control group, 18.4% for GG and 68.6% for GA/AA in the entire group with gastric lesions and 17.9% for GG and 82.1% for GA/AA in the group with gastric adenocarcinoma. No statistically significant associations were found between EGF +61 variants and risk for developing gastric cancer [odds ratios (OR) = 1.41, 95% confidence intervals (CI): 0.90-2.21, P = 0.116]. However, the stratification of individuals by gender revealed that males carrying A alleles (EGF +61A/G or AA) had an increased risk for developing gastric cancer as compared to GG homozygous males (OR = 1.55, 95% CI: 1.05-2.28, P = 0.021). CONCLUSION: In summary, we found that males who were A carriers for EGF +61 had an increased risk for developing gastric cancer. This result may be explained by the suggestion that women secrete less gastric acid than men. | Ana Paula Araújo Bruno M Costa Ana L Pinto-Correia Maria Fragoso Paula Ferreira Mário Dinis-Ribeiro Sandra Costa Rui M Reis Rui Medeiros | 2011 | World Journal of Gastroenterology2011,17,4: | 3 |

| 8 | How to manage inflammatory bowel disease during the COVID-19 pandemic:A guide for the practicing clinician显示文摘Managing inflammatory bowel disease(IBD)during the coronavirus disease 2019(COVID-19)pandemic has been a challenge faced by clinicians and their patients,especially concerning whether to proceed with biologics and immunosuppressive agents in the background of a global outbreak of a highly contagious new coronavirus(severe acute respiratory syndrome coronavirus 2,SARS-CoV-2).The knowledge about the impact of this virus on patients with IBD,although it is still scarce,is rapidly evolving.In particular,concerns surrounding medications’impact for IBD on the risk of acquiring SARS-CoV-2 infection or developing COVID-19,and potentially exacerbate viral replication and the COVID-19 course,are a current thinking of both practicing clinicians and providers caring for patients with IBD.Managing patients with IBD infected with SARS-CoV-2 depends on both the clinical activity of the IBD and the occasional development and severity of COVID-19.In this review,we summarize the current data regarding gastrointestinal involvement by SARS-CoV-2 and pharmacologic and surgical management for IBD concerning this infection,and the COVID-19 impact on both the patient's psychological functioning and endoscopy services,and we concisely summarize the telemedicine roles during the COVID-19 pandemic. | Júlio Maria Fonseca Chebli Natália Sousa Freitas Queiroz Adérson Omar Mourão Cintra Damião Liliana Andrade Chebli Márcia Henriques de Magalhães Costa Rogério Serafim Parra | 2021 | World Journal of Gastroenterology2021,27,11: | 2 |
| 9 | Serum vitamin D content is associated with semen|parameters and serum testosterone levels in men显示文摘The present study aimed to evaluate the influence of serum vitamin D levels on semen quality and testosterone levels.This is a crosssectional study conducted at Androscience,Science and Innovation Center in Andrology and High-Complex Clinical and Andrology Laboratory in Sao Paulo,Brazil,with 508 male patients,aged 18-60 years,from 2007 to 2017.Seminal parameters and serum sexual hormones were correlated with serum vitamin D concentrations in 260 men selected by strict selection criteria.Patients were divided into normozoospermic group(NZG,n=124)and a group with seminal abnormalities(SAG,n=136).Evaluation included complete physical examination,past medical history,habits and lifestyle factors,two complete seminal analysis with sperm functional tests,serum levels of 25-hydroxy-vitamin D_(3)(25(OH)VD_(3)),total and free testosterone,luteinizing hormone(LH),follicle-stimulating hormone(FSH),sex hormone-binding globulin(SHBG),total cholesterol,homeostatic model assessment of insulin resistance(HOMA-IR)index,and karyotype.The mean concentration of 25(OH)VD_(3)was significantly lower in the SAG(P<0.001)and positively correlated with all baseline seminal parameters and total testosterone levels.In addition,serum vitamin D_(3)concentration was found to be positively correlated with sperm concentration(β=2.103;P<0.001),total number of spermatozoa with progressive motility(β=2.069;P=0.003),total number of motile spermatozoa(β=2.571;P=0.015),and strict morphology(β=0.056;P=0.006),regardless of other variables.This is the first comparative study to address the issue of serum vitamin D_(3)content between normozoospermic patients and those with sperm abnormalities.It clearly demonstrates a direct and positive relationship between serum vitamin D level and overall semen quality,male reproductive potential,and testosterone levels. | Inari M Ciccone Elaine MF Costa Juliana R Pariz Thiago A Teixeira Joel R Drevet Parviz Gharagozloo Robert J Aitken Jorge Hallak | 2021 | Asian Journal of Andrology2021,23,1: | 2 |
| 10 | Resveratrol attenuates metabolic,sperm,and testicular changes in adult Wistar rats fed a diet rich in lipids and simple carbohydrates显示文摘High-fat diets affect male reproduction and sexual function.Therefore,we evaluated the effects of prolonged resveratrol administration on the metabolic,sperm,and testicular parameters of rats fed a cafeteria diet.Male Wistar rats were divided at weaning into control(Cv n=20)and cafeteria(CAF,n=16)groups.At 3 months,half of them were given daily supplementations of resveratrol(C-R,n=10;CAF-R,n=8)at a dosage of 30 mg kg-1 body mass for 2 months.Animals were killed at 5 months of age,and blood,spermatozoa,and testes were collected for further analysis.Data were analyzed by one-way ANOVA,and P<0.05 was considered statistically significant.The CAF diet promoted hyperglycemia(P<0.0001),and treatment with resveratrol reversed this condition(P<0.0001).The CAF diet reduced sperm viability and motility,while resveratrol improved these parameters(F<0.05).Regarding testicular morphology,the height of the seminiferous epithelium was reduced in the CAF group compared with that of the C group(P=0.0007).Spermatogenic cell proliferation was also reduced in the CAF group compared with that of the C group.However,the CAF-R showed an increase in cell proliferation rate compared with that of the untreated CAF group(P=0.0024).Although it did not modify body mass,the consumption of a CAF diet promoted hyperglycemia,adverse testicular morphology remodeling,and abnormal sperm,which were attenuated by treatment with resveratrol,thus suggesting a protective effect of this antioxidant on spermatogenesis. | Fabiana A de Oliveira Waldemar S Costa Francisco J B Sampaio Bianca M Gregorio | 2019 | Asian Journal of Andrology2019,21,2: | 2 |
| 11 | Development of hepatorenal syndrome in bile duct ligated rats显示文摘AIM: To evaluate in bile duct ligated rats whether there were progressive alterations of renal function without changes in histopathology. METHODS: Male Wistar rats were submitted to sham-surgery or bile duct ligation (BDL) and divided according to the post-procedure time (2, 4 and 6-wk). To determine renal function parameters, rats wereplaced in metabolic cages and, at the end of the experiment, blood and urine samples were obtained. Histology and hydroxyproline content were analyzed in liver and renal tissue. RESULTS: Rats with 2 wk of BDL increased free water clearance (P = 0.02), reduced urinary osmolality (P = 0.03) and serum creatinine (P = 0.01) in comparison to the sham group. In contrast, rats at 6 wk of BDL showed features of HRS, including signif icant increase in serum creatinine and reductions in creatinine clearance, water excretion and urinary sodium concentration. Rats with 4 wk of BDL exhibited an intermediate stage of renal dysfunction. Progressive hepatic f ibrosis according to post-procedure time was confirmed by histology. The increased levels of liver hydroxyproline contrasted with the absence of structural changes in the kidney, as assessed by histology and unchanged hydroxyproline content in renal tissue. CONCLUSION: Our data show that BDL produced progressive renal dysfunction without structural changes in the kidney, characterizing HRS. The present model will be useful to understand the pathophysiology of HRS. | Regina M Pereira Robson AS dos Santos Eduardo A Oliveira Virgínia HR Leite Filipi LC Dias Alysson S Rezende Lincoln P Costa Lucíola S Barcelos Mauro M Teixeira Ana Cristina Sim■es e Silva | 2008 | World Journal of Gastroenterology2008,14,28: | 2 |
| 12 | Non-pharmacological management of pediatric functional abdominal pain disorders:Current evidence and future perspectives显示文摘Functional abdominal pain disorders(FAPDs) are an important and prevalent cause of functional gastrointestinal disorders among children, encompassing the diagnoses of functional dyspepsia, irritable bowel syndrome, abdominal migraine, and the one not previously present in Rome Ⅲ, functional abdominal pain not otherwise specified. In the absence of sufficiently effective and safe pharmacological treatments for this public problem, non-pharmacological therapies emerge as a viable means of treating these patients, avoiding not only possible side effects, but also unnecessary prescription, since many of the pharmacological treatments prescribed do not have good efficacy when compared to placebo. Thus, the present study provides a review of current and relevant evidence on non-pharmacological management of FAPDs, covering the most commonly indicated treatments, from cognitive behavioral therapy to meditation, acupuncture, yoga, massage, spinal manipulation, moxibustion, and physical activities. In addition, this article also analyzes the quality of publications in the area, assessing whether it is possible to state if non-pharmacological therapies are viable, safe, and sufficiently well-based for an appropriate and effective prescription of these treatments. Finally, it is possible to observe an increase not only in the number of publications on the non-pharmacological treatments for FAPDs in recent years, but also an increase in the quality of these publications. Finally, the sample selection of satisfactory age groups in these studies enables the formulation of specific guidelines for this age group, thus avoiding the need for adaptation of prescriptions initially made for adults, but for children use. | Maria Luísa Cordeiro Santos Ronaldo Teixeira da Silva Júnior Breno Bittencourt de Brito Filipe Antônio França da Silva Hanna Santos Marques Vinícius Lima de SouzaGonçalves Talita Costa dos Santos Carolina Ladeia Cirne Natália Oliveira e Silva Márcio Vasconcelos Oliveira Fabrício Freire de Melo | 2022 | World Journal of Clinical Pediatrics2022,11,2: | 2 |

| 15 | Energetic-protein supplementation in the last 60 days of gestation improves performance of beef cows grazing tropical pastures显示文摘Background: Nutrition is one of the most important factors that affect animal performance, and it therefore also impacts on financial results in beef systems. In this way, finding the best strategy for feeding supplements is of paramount importance. Aiming to evaluate the effect of supplement feeding strategies for beef cows in the last third of gestation, two experiments were conducted. In Experiment 1, 35 pregnant Nellore cows were assigned to a completely randomized design with four treatments: control, which received no supplement; supplementation for the last 30 d of gestation(30-d; 3.0 kg/d); supplementation for the last 60 d of gestation(60-d; 1.5 kg/d); or supplementation for the last 90 d of gestation(90-d; 1.0 kg/d). All supplemented treatments received the same total amount of supplement throughout the experiment: 90 kg(20% of crude protein). A second experiment(Experiment 2) was delineated to evaluate the effects of the amounts offered in Experiment 1 on intake and metabolism. Four multiparous pregnant Nellore cows were assigned to a 4 × 4 Latin square design, with periods of15 d each.Results: There was a linear effect of the number of days of supplementation on calving body weight(BW; P < 0.05)and a quadratic effect on BW change from parturition to d 31 post-calving(P < 0.05), with cows on the 60-d strategy losing less BW post-calving. No difference was found in offspring birth BW(P > 0.10). A significant linear effect on interval from parturition to conception(P < 0.05) was observed, with the highest calving to conception interval being observed in the 90-d strategy. The level of supplementation did not affect forage intake or neutral detergent fiber digestibility(P > 0.10). Nitrogen excreted through urine tended to increase linearly with the level of supplementation(P < 0.10).Conclusion: Providing 1.5 kg of supplement during the last 60 d of gestation improves cow performance after calving, reducing the magnitude of BW lost, and reduces the number of days from calving to re-conception in the following breeding season compared to the usually recommended period of supplementation of 90 d pre-partum. | Aline Gomes da Silva Mário Fonseca Paulino Edenio Detmann Henrique Jorge Fernandes Lincoln da Silva Amorim Román Enrique Maza Ortega Victor Valério de Carvalho Josilaine Aparecida da Costa Lima Felipe Henrique de Moura Mariana Benevides Monteiro Jéssika Almeida Bitencourt | 2018 | Journal of Animal Science and Biotechnology2018,9,1: | 2 |
