| 1 | 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 |
| 2 | Imaging response predictors following drug eluting beads chemoembolization in the neoadjuvant liver transplant treatment of hepatocellular carcinoma显示文摘BACKGROUND Drug-eluting bead transarterial chemoembolization(DEB-TACE)is an endovascular treatment to release chemotherapeutic agents within a target lesion,minimizing systemic exposure and adverse effects to chemotherapeutics.Therefore,identifying which patient characteristics may predict imaging response to DEB-TACE can improve treatment results while selecting the best candidates.Predictors of the response after DEB-TACE still have not been fully elucidated.This is the first prospective study performed with standardized DEBTACE technique that aim to identify predictors of radiological response,assessing patients clinical and laboratory characteristics,diagnostic imaging and intraprocedure data of the hepatocellular carcinoma treated in the neoadjuvant context for liver transplantation.AIM To identify pre-and intraoperative clinical and imaging predictors of the radiological response of drug-eluting bead transarterial chemoembolization(DEB-TACE)for the neoadjuvant treatment of hepatocellular carcinoma(HCC).METHODS This is prospective,cohort study,performed in a single transplant center,from 2011 to 2014.Consecutive patients with HCC considered for liver transplant who underwent DEB-TACE in the first session for downstaging or bridging purposes were recruited.Pre and post-chemoembolization imaging studies were performed by computed tomography or magnetic resonance.The radiological response of each individual HCC was evaluated by objective response using mRECIST and the percentage of necrosis.RESULTS Two hundred patients with 380 HCCs were examined.Analysis of the objective response(nodule-based analysis)demonstrated that HCC with pseudocapsules had a 2.01 times greater chance of being responders than those without pseudocapsules(P=0.01),and the addition of every 1mg of chemoembolic agent increased the chance of therapeutic response in 4%(P<0.001).Analysis of the percentage of necrosis through multiple linear regression revealed that the addition of each 1mg of the chemoembolic agent caused an average increase of 0.65%(P<0.001)in necrosis in the treated lesion,whereas the hepatocellular carcinoma with pseudocapsules presented 18.27%(P<0.001)increased necrosis compared to those without pseudocapsules.CONCLUSION The presence of a pseudocapsule and the addition of the amount of chemoembolic agent increases the chance of an objective response in hepatocellular carcinoma and increases the percentage of tumor necrosis following drug-eluting bead chemoembolization in the neoadjuvant treatment,prior to liver transplantation. | Francisco Leonardo Galastri Felipe Nasser Breno Boueri Affonso Leonardo Guedes Moreira Valle Bruno Calazans Odísio Joaquim Mauricio Motta-Leal Filho Paolo Rogério Salvalaggio Rodrigo Gobbo Garcia Márcio Dias de Almeida Ronaldo Hueb Baroni Nelson Wolosker | 2020 | World Journal of Hepatology2020，12，1： | 2 |
| 3 | 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 |
