1Diagnostic and prognostic potential of tissue and circulating long non-coding RNAs in colorectal tumors显示文摘Long non-coding RNAs(lncRNAs)are members of the non-protein coding RNA family longer than 200 nucleotides.They participate in the regulation of gene and protein expression influencing apoptosis,cell proliferation and immune responses,thereby playing a critical role in the development and progression of various cancers,including colorectal cancer(CRC).As CRC is one of the most frequently diagnosed malignancies worldwide with high mortality,its screening and early detection are crucial,so the identification of disease-specific biomarkers is necessary.LncRNAs are promising candidates as they are involved in carcinogenesis,and certain lncRNAs(e.g.,CCAT1,CRNDE,CRCAL1-4)show altered expression in adenomas,making them potential early diagnostic markers.In addition to being useful as tissue-specific markers,analysis of circulating lncRNAs(e.g.,CCAT1,CCAT2,BLACAT1,CRNDE,NEAT1,UCA1)in peripheral blood offers the possibility to establish minimally invasive,liquid biopsy-based diagnostic tests.This review article aims to describe the origin,structure,and functions of lncRNAs and to discuss their contribution to CRC development.Moreover,our purpose is to summarise lncRNAs showing altered expression levels during tumor formation in both colon tissue and plasma/serum samples and to demonstrate their clinical implications as diagnostic or prognostic biomarkers for CRC.Orsolya Galamb Barbara K Barták Alexandra Kalmár Zsófia B Nagy Krisztina A Szigeti Zsolt Tulassay Peter Igaz Béla Molnár 2019World Journal of Gastroenterology2019,25,34:18

3Alcohol,nutrition and liver cancer:Role of Toll-like receptor signaling显示文摘This article reviews the evidence that ties the development of hepatocellular carcinoma (HCC) to the natural immune pro-inflammatory response to chronic liver disease, with a focus on the role of Toll-like receptor (TLR) signaling as the mechanism of liver stem cell/progenitor transformation to HCC. Two exemplary models of this phenomenon are reviewed in detail. One model applies chronic ethanol/lipopolysaccharide feeding to the activated TLR4 signaling pathway. The other applies chronic feeding of a carcinogenic drug, in which TLR2 and 4 signaling pathways are activated. In the drug-induced model, two major methyl donors, S-adenosylmethionine and betaine, prevent the upregulation of the TLR signaling pathways and abrogate the stem cell/progenitor proliferation response when fed with the carcinogenic drug. This observation supports a nutritional approach to liver cancer prevention and treatment. The observation that upregulation of the TLR signaling pathways leads to liver tumor formation gives evidence to the popular concept that the chronic pro-inflammatory response is an important mechanism of liver oncogenesis. It provides a nutritional approach, which could prevent HCC from developing in many chronic liver diseases.Samuel W French Joan Oliva Barbara A French Fawzia Bardag-Gorce 2010World Journal of Gastroenterology2010,16,11:11
4Influence of silybin on biophysical properties of phospholipid bilayers显示文摘Aim:Silybin(silibinin)is major biologically active flavonolignan extracted frommilk thistle(Sylibum marianum).Its biological activities include hepato-protection,anticancer properties,and antioxidant-and membrane-stabilizing functions.Al-though membranes are postulated to be one of the cellular targets for silybin,littleis known about its interaction with phospholipid bilayers.Methods:In the presentwork,the interactions of silybin with phosphatidylcholine bilayers were studiedin detail using fluorescence spectroscopy,microcalorimetry and electron spinresonance techniques.Results:The results showed that silybin interacted withthe surface of lipid bilayers.It affected the generalized polarization of the fluores-cent probe Prodan,while not influencing the more deeply located Laurdan.Silybinlowered the main phospholipid phase transition temperature as judged bymicrocalorimetry,and caused the immobilization of spin probe Tempo-palmitatelocated on the surface of membranes.The mobility of spin probes 5-and 16-doxylstearic acid was not affected by silybin.Silybin-induced quenching of 1,6-diphe-nyl-1,3,5-hexatriene fluorescence indicated that some flavonoid molecules parti-tioned into the hydrophobic region of membranes,which did not change signifi-cantly the biophysical properties of the deeper membrane regions.Conclusion:Such a behavior of silybin in membranes is in accordance with its postulatedbiological functions and neglectable side effects of therapies using silybin.OlgaWESO£OWSKA Barbara£ANIA-PIETRZAK MichaKU~-D~-A£ KamilaSTAN~CZAK DanielaMOSI PiotrDOBRYSZYCKI AndrzejO~-YHAR Magorzata KOMOROWSKA AndrzejBHENDRICH KrystynaMICHALAK 2007Acta Pharmacologica Sinica2007,28,2:11
5Efficacy and safety of tenofovir in chronic hepatitis B: Australian real world experience显示文摘AIM To evaluate the long-term treatment outcomes of tenofovir therapy in patients in a real world Australian tertiary care setting.METHODS We performed a retrospective analysis of treatment outcomes among treatment-na?ve and treatment-experienced patients receiving a minimum 3 mo tenofovir therapy through St Vincent's Hospital Melbourne, Australia. We included patients receiving tenofovir [tenofovir disoproxil fumarate(TDF)] monotherapy, as well as patients treated with TDF in combination with a second antiviral agent. Patients were excluded if they demonstrated human immune-deficiency virus/hepatitis C virus/hepatitis delta virus coinfection or were less than 18 years of age. We considered virological and biochemicalresponse, as well as safety outcomes. Virological response was determined by measurement of hepatitis B virus(HBV) DNA using sensitive assays; biochemical response was determined via serum liver function tests; histological response was determined from liver biopsy and fibroscan; safety analysis focused on glomerular renal function and bone mineral density. The primary efficacy endpoint was complete virological suppression over time, defined by HBV DNA < 20 IU/m L. Secondary efficacy endpoints included rates of biochemical response, and HB e antigen(HBe Ag)/HB surface antigen loss and seroconversion over time.RESULTS Ninety-two patients were identified who fulfilled the enrolment criteria. Median follow-up was 26 mo(range 3-114). Mean age was 46(24-78) years, 64(70%) were male and 77(84%) were of Asian origin. 55(60%) patients were treatment-na?ve and 62 patients(67%) were HBe Ag-negative. Complete virological suppression was achieved by 45/65(71%) patients at 12 mo, 37/46(80%) at 24 mo and 25/28(89%) at 36 mo. Partial virological response(HBV DNA 20-2000 IU/m L) was achieved by 89/92(96.7%) of patients. Multivariate analysis showed a significant relationship between virological suppression at end of follow-up and baseline HBV DNA level(OR = 0.897, 95%CI: 0.833-0.967, P = 0.0046) and HBe Ag positive status(OR = 0.373, 95%CI: 0.183-0.762, P = 0.0069). There was no difference in response comparing treatment-na?ve and treatment-experienced patients. Three episodes of virological breakthrough occurred in the setting of noncompliance. Tenofovir therapy was well tolerated.CONCLUSION Tenofovir is an efficacious, safe and well-tolerated treatment in an Australian real-world tertiary care setting. Our data are similar to the reported experience from registration trials.Grace C Lovett Tin Nguyen David M Iser Jacinta A Holmes Robert Chen Barbara Demediuk Gideon Shaw Sally J Bell Paul V Desmond Alexander J Thompson 2017World Journal of Hepatology2017,9,1:7
6Burden of Clostridium difficile infection between 2010 and 2013:Trends and outcomes from an academic center in Eastern Europe显示文摘AIM:To analyze the incidence and possible risk factors in hospitalized patients treated with Clostridium difficile infection(CDI).METHODS:A total of 11751 patients were admitted to our clinic between 1 January 2010 and 1 May2013.Two hundred and forty-seven inpatients were prospectively diagnosed with CDI.For the risk analysis a 1:3 matching was used.Data of 732 patients matched for age,sex,and inpatient care period and unit were compared to those of the CDI population.Inpatient records were collected from an electronic hospital database and comprehensively reviewed.RESULTS:Incidence of CDI was 21.0/1000 admissions(2.1%of all-cause hospitalizations and 4.45%of total inpatient days).The incidence of severe CDI was 12.6%(2.63/1000 of all-cause hospitalizations).Distribution of CDI cases was different according to the unit type,with highest incidence rates in hematology,gastroenterology and nephrology units(32.9,25 and24.6/1000 admissions,respectively) and lowest rates in 1.4%(33/2312) in endocrinology and general internal medicine(14.2 and 16.9/1000 admissions)units.Recurrence of CDI was 11.3%within 12 wk after discharge.Duration of hospital stay was longer in patients with CDI compared to controls(17.6 ± 10.8d vs 12.4 ± 7.71 d).CDI accounted for 6.3%of allinpatient deaths,and 30-d mortality rate was 21.9%(54/247 cases).Risk factors for CDI were antibiotic therapy[including third-generation cephalosporins or fluoroquinolones,odds ratio(OR) = 4.559;P < 0.001],use of proton pump inhibitors(OR = 2.082,P< 0.001),previous hospitaiization within 12 mo(OR = 3.167,P < 0.001),previous CDI(OR = 15.32;P < 0.001),while presence of diabetes mellitus was associated with a decreased risk for CDI(OR = 0.484;P< 0.001).Treatment of recurrent cases was significantly different from primary infections with more frequent use of vancomycin alone or in combination(P < 0.001),and antibiotic therapy duration was longer(P < 0.02).Severity,mortality and outcome of primary infections and relapsing cases did not significantly differ.CONCLUSION:CDI was accounted for significant burden with longer hospitaiization and adverse outcomes.Antibiotic,PPI therapy and previous hospitaiization or CDI were risk factors for CDI.Zsuzsanna Kurti Barbara D Lovasz Michael D Mandel Zoltan Csima Petra A Golovics Bence D Csako Anna Mohas Lorant Gnczi Krisztina B Gecse Lajos S Kiss Miklos Szathmari Peter L Lakatos 2015World Journal of Gastroenterology2015,21,21:6

8Solid phase microextraction chemical biopsy tool for monitoring of doxorubicin residue during in vivo lung chemo-perfusion显示文摘Development of a novel in vivo lung perfusion(IVLP)procedure allows localized delivery of high-dose doxorubicin(DOX)for targeting residual micrometastatic disease in the lungs.However,DOX delivery via IVLP requires careful monitoring of drug level to ensure tissue concentrations of this agent remain in the therapeutic window.A small dimension nitinol wire coated with a sorbent of biocompatible morphology(Bio-SPME)has been clinically evaluated for in vivo lung tissue extraction and determination of DOX and its key metabolites.The in vivo Bio-SPME-IVLP experiments were performed on pig model over various(150 and 225 mg/m^(2))drug doses,and during human clinical trial.Two patients with metastatic osteosarcoma were treated with a single 5 and 7 μg/mL(respectively)dose of DOX during a 3-h IVLP.In both pig and human cases,DOX tissue levels presented similar trends during IVLP.Human lung tissue concentrations of drug ranged between 15 and 293 μg/g over the course of the IVLP procedure.In addition to DOX levels,Bio-SPME followed by liquid chromatography-mass spectrometry analysis generated 64 metabolic features during endogenous metabolite screening,providing information about lung status during drug administration.Real-time monitoring of DOX levels in the lungs can be performed effectively throughout the IVLP procedure by in vivo Bio-SPME chemical biopsy approach.Bio-SPME also extracted various endogenous molecules,thus providing a real-time snapshot of the physiology of the cells,which might assist in the tailoring of personalized treatment strategy.Barbara Bojko Nikita Looby Mariola Olkowicz Anna Roszkowska Bogumiła Kupcewicz Pedro Reck dos Santos Khaled Ramadan Shaf Keshavjee Thomas K.Waddell German Goomez-Rios Marcos Tascon Krzysztof Gorynski Marcelo Cypel Janusz Pawliszyn 2021Journal of Pharmaceutical Analysis2021,11,1:3
9Thiopurine-methyltransferase variants in inflammatory bowel disease:Prevalence and toxicity in Brazilian patients显示文摘AIM:To analyze the prevalence of thiopurine-methyltransferase(TPMT)genotypes and their associationwith drug toxicity in inflammatory bowel disease(IBD)patients from southeastern Brazil.METHODS:A total of 219 consecutive patients with IBD,of which 146 had Crohn’s disease and 73 had ulcerative colitis,regularly seen at the outpatient unit of the Division of Gastroenterology at the University Hospital Pedro Ernesto of the State University of Rio de Janeiro,a tertiary referral center,were enrolled in this study from February 2009 to January 2011.We analyzed the presence of major TPMT genetic variants(TPMT*2,*3A,*3C)in IBD patients by means of a specific allele and RFLP-PCR.Genomic DNA was isolated from peripheral blood leukocytes by proteinase-K/Sodium Dodecyl Sulfate digestion and phenol-chloroform extraction.TPMT*2(C238G),TPMT*3A(G460A/A719G),and TPMT*3C(A719G)genotypes were detected by real-time polymerase chain reaction followed by direct sequencing with specific primers.Clinical data were systematically recorded,and correlated with the genotype results.RESULTS:The distribution of the selected TPMT gene polymorphism TPMT*2(C238G),TPMT*3A(G460A/A719G),and TPMT*3C(A719G)genotypes was 3.6%,5.4%,and 7.7%of the patients,respectively.Among the side effects recorded from patients taking azathioprine,14 patients presented with pancreatitis and/or an elevation of pancreatic enzymes,while 6 patients had liver toxicity,and 2 patients exhibited myelosuppression/neutropenia.TPMT polymorphisms were detected in 37/219 patients(8 heterozygous for*2,11 heterozygous for*3A,and 18 heterozygous for*3C).No homozygotic polymorphisms were found.Despite the prevalence of the TPMT*3C genotype,no differences among the genotype frequencies were significant.Although no association was detected regarding myelotoxicity or hepatotoxicity,a trend towards the elevation of pancreatic enzymes was observed for TPMT*2 and TPMT*3C genotypes.CONCLUSION:The prevalence of TPMT genotypes was high among Brazilian patients.Variants genes*2and*3C may be associated with azathioprine pancreatic toxicity in a IBD southeastern Brazilian population.Ana Teresa P Carvalho Barbara C Esberard Renata S B Fróes Davy C M Rapozo Ana B Grinman Tatiana A Simo Juliana C V C Santos Antonio José V Carneiro Luis Felipe Ribeiro-Pinto Heitor S P de Souza 2014World Journal of Gastroenterology2014,20,12:3
10Repeat endoscopic retrograde cholangiopancreaticography after failed initial precut sphincterotomy for biliary cannulation显示文摘AIM: To investigate the outcome of repeating endoscopic retrograde cholangiopancreaticography(ERCP) after initially failed precut sphincterotomy to achieve biliary cannulation.METHODS: In this retrospective study, consecutive ERCPs performed between January 2009 and September 2012 were included. Data from our endoscopy and radiology reporting databases were analysed for use of precut sphincterotomy, biliary access rate, repeat ERCP rate and complications. Patients with initially failed precut sphincterotomy were identified.RESULTS: From 1839 consecutive ERCPs, 187(10%) patients underwent a precut sphincterotomy during the initial ERCP in attempts to cannulate a native papilla. The initial precut was successful in 79/187(42%). ERCP was repeated in 89/108(82%) of patients with failed initial precut sphincterotomy after a median interval of 4 d, leading to successful biliary cannulation in 69/89(78%). In 5 patients a third ERCP was attempted(successful in 4 cases). Overall, repeat ERCP after failed precut at the index ERCP was successful in 73/89 patients(82%). Complications after precut-sphincterotomy were observed in 32/187(17%) patients including pancreatitis(13%), retroperitoneal perforations(1%), biliary sepsis(0.5%) and haemorrhage(3%).CONCLUSION: The high success rate of biliary cannulation in a second attempt ERCP justifies repeating ERCP within 2-7 d after unsuccessful precut sphincterotomy before more invasive approaches should be considered.Michael Pavlides Ashley Barnabas Nilesh Fernandopulle Adam A Bailey Jane Collier Jane Phillips-Hughes Anthony Ellis Roger Chapman Barbara Braden 2014World Journal of Gastroenterology2014,20,36:3
11扁桃体鳞癌中HPV感染与EGFR、VEGF表达的相关性研究显示文摘目的:研究扁桃体鳞癌(squamous cell carcinomas of the tonsil tonsillar,SCCs)中人乳头瘤病毒(human papillomavirus,HPV)感染与血管内皮生长因子(vascular endothelial growth factor,VEGF)和表皮生长因子受体(epidermal growth factor,EGFR)表达的关系,探讨HPV与EGFR和VEGF在扁桃体鳞癌发生中的交互效应。方法:采用多重实时荧光定量聚合酶链反应(multiplex real-time polymerase chain reaction,MT-PCR)检测85例扁桃体鳞癌HPV DNA及型别,通过HPV DNA分析进行HPV感染状况的测定;同时采用半定量免疫组化检测HPV(+)组和HPV(-)组中VEGF、EGFR蛋白表达情况。结果:扁桃体鳞癌中HPV感染率为49.4%(42/85),HPV-16型占所有感染者的比例为90.5%(38/42),明显高于其他型别;HPV(+)组EGFR蛋白表达明显低于HPV(-)组(P值均<0.01);HPV(+)组与HPV(-)组VEGF蛋白表达无明显差异;此外,VEGF表达与EGFR、患者的年龄、性别、TNM分期、组织学分级均无明显相关性。结论:HPV感染与扁桃体鳞癌的发生存在相关性,HPV相关的扁桃体鳞癌中,HPV基因可能通过改变EGFR表达致癌,为HPV致癌机理进一步研究提供一个新的视角,具有重要的理论意义。费继敏 Timothy A Dobbins Deanna Jones C Soon Lee Christine Loo Jonathan Clark Barbara Rose 2015现代肿瘤医学2015,23,4:3
12National Forest Inventories capture the multifunctionality of managed forests in Germany显示文摘Background:Forests perform various important ecosystem functions that contribute to ecosystem services.In many parts of the world,forest management has shifted from a focus on timber production to multi-purpose forestry,combining timber production with the supply of other forest ecosystem services.However,it is unclear which forest types provide which ecosystem services and to what extent forests primarily managed for timber already supply multiple ecosystem services.Based on a comprehensive dataset collected across 150 forest plots in three regions differing in management intensity and species composition,we develop models to predict the potential supply of 13 ecosystem services.We use those models to assess the level of multifunctionality of managed forests at the national level using national forest inventory data.Results:Looking at the potential supply of ecosystem services,we found trade-offs(e.g.between both bark beetle control or dung decomposition and both productivity or soil carbon stocks)as well as synergies(e.g.for temperature regulation,carbon storage and culturally interesting plants)across the 53 most dominant forest types in Germany.No single forest type provided all ecosystem services equally.Some ecosystem services showed comparable levels across forest types(e.g.decomposition or richness of saprotrophs),while others varied strongly,depending on forest structural attributes(e.g.phosphorous availability or cover of edible plants)or tree species composition(e.g.potential nitrification activity).Variability in potential supply of ecosystem services was only to a lesser extent driven by environmental conditions.However,the geographic variation in ecosystem function supply across Germany was closely linked with the distribution of main tree species.Conclusions:Our results show that forest multifunctionality is limited to subsets of ecosystem services.The importance of tree species composition highlights that a lack of multifunctionality at the stand level can be compensated by managing forests at the landscape level,when stands of complementary forest types are combined.These results imply that multi-purpose forestry should be based on a variety of forest types requiring coordinated planning across larger spatial scales.Nadja K.Simons María R.Felipe-Lucia Peter Schall Christian Ammer Jürgen Bauhus Nico Blüthgen Steffen Boch François Buscot Markus Fischer Kezia Goldmann Martin M.Gossner Falk Hänsel Kirsten Jung Peter Manning Thomas Nauss Yvonne Oelmann Rodica Pena Andrea Polle Swen C.Renner Michael Schloter Ingo Schöning Ernst-Detlef Schulze Emily F.Solly Elisabeth Sorkau Barbara Stempfhuber Tesfaye Wubet Jörg Müller Sebastian Seibold Wolfgang W.Weisser 2021Forest Ecosystems2021,8,1:2
13Transposon mouse models to elucidate the genetic mechanisms of hepatitis B viral induced hepatocellular carcinoma显示文摘The major type of human liver cancer is hepatocellular carcinoma(HCC), and there are currently many risk factors that contribute to this deadly disease. The majority of HCC occurrences are associated with chronic hepatitis viral infection, and hepatitis B viral(HBV) infection is currently a major health problem in Eastern Asia. Elucidating the genetic mechanisms associated with HBV-induced HCC has been difficult due to the heterogeneity and genetic complexity associated with this disease. A repertoire of animal models has been broadly used to study the pathophysiology and to develop potential treatment regimens for HBVassociated HCC. The use of these animal models has provided valuable genetic information and has been an important contributor to uncovering the factors involved in liver malignant transformation, invasion and metastasis. Recently, transposon-based mouse models are becoming more widely used in liver cancer research to interrogate the genome by forward genetics and also used to validate genes rapidly in a reverse genetic manner. Importantly, these transposon-based rapid reverse genetic mouse models could become crucial in testing potential therapeutic agents before proceeding to clinical trials in human. Therefore, this review will cover the use of transposon-based mouse models toaddress the problems of liver cancer, especially HBVassociated HCC occurrences in Asia.Amy P Chiu Barbara R Tschida Lilian H Lo Branden S Moriarity Dewi K Rowlands David A Largaespada Vincent W Keng 2015World Journal of Gastroenterology2015,21,42:2
14Inflammatory bowel disease course in Crohn's disease:Is the natural history changing?显示文摘Crohn’s disease(CD)is a multifactorial potentially debilitating disease.It has a variable disease course,but the majority of patients eventually develop penetrating or stricturing complications leading to repeated surgeries and disability.Studies on the natural history of CD provide invaluable data on its course and clinical predictors,and may help to identify patient subsets based on clinical phenotype.Most data are available from referral centers,however these outcomes may be different from those in population-based cohorts.New data suggest the possibility of a change in the natural history in Crohn’s disease,with an increasing percentage of patients diagnosed with inflammatory disease behavior.Hospitalization rates remain high,while surgery rates seem to have decreased in the last decade.In addition,mortality rates still exceed that of the general population.The impact of changes in treatment strategy,including increased,earlier use of immunosuppressives,biological therapy,and patient monitoring on the natural history of the disease are still conflictive.In this review article,the authors summarize the available evidence on the natural history,current trends,and predictive factors for evaluating the disease course of CD.Petra A Golovics Michael D Mandel Barbara D Lovasz Peter L Lakatos 2014World Journal of Gastroenterology2014,20,12:2

19Gastric hyperplastic polyps causing upper gastrointestinal hemorrhage in a young adult显示文摘Here, we report a case of a young man who presented with a significant upper gastrointestinal bleed treated by endoscopic removal of multiple hyperplastic polyps. Gastric hyperplastic polyps are a relatively uncommon cause of overt gastrointestinal bleeding. While most hyperplastic gastric polyps are asymptomatic, they may present with abdominal pain, iron def iciency anemia or gastric outlet obstruction. These polyps are associated with conditions such as Helicobacter pylori gastritis and atrophic autoimmune gastritis, which predispose the epithelium to chronic inf lammation and epithelial repair.The patient presented to Northwestern Memorial Hospital in July 2011. The polyps were resected by clip-assisted snare polypectomy. Histopathologic assessment of the resected polyps demonstrated multiple, nonulcerative hyperplastic polyps measuring 1.3-1.8 cm in size, without evidence of dysplasia or malignancy. This case describes a young adult patient with multiple, large gastric polyps causing overt gastrointestinal bleeding. This is a rare presentation in a young individual, as these polyps are typically identifi ed in patients older than 60 years of age and less commonly, pediatric populations.Brian J Secemsky Kenika R Robinson Kumar Krishnan Kristina A Matkowskyj Barbara H Jung 2013World Journal of Clinical Cases2013,1,1:2
20Prevalence and predictors of hospitalization in Crohn's disease in a prospective population-based inception cohort from 2000-2012显示文摘AIM: To analyze the prevalence, length and predictors of hospitalization in the biological era in the populationbased inception cohort from Veszprem province.METHODS: Data of 331 incident Crohn's disease(CD) patients diagnosed between January 1, 2000 and December 31, 2010 were analyzed(median age at diagnosis: 28; IQR: 21-40 years). Both in- and outpatient records were collected and comprehensively reviewed.RESULTS: Probabilities of first CD-related hospitalization and re-hospitalization were 32.3%, 45.5%,53.7% and 13.6%, 23.9%, 29.8%, respectively after one, three and five years of follow-up in Kaplan-Meier analysis. First-year hospitalizations were related to diagnostic procedures(37%), surgery or disease activity(27% and 21%). Non-inflammatory disease behavior at diagnosis(HR = 1.32, P = 0.001) and perianal disease(HR = 1.47, P = 0.04) were associated with time to first CD-related hospitalization, while disease behavior change(HR = 2.38, P = 0.002) and need for steroids(HR = 3.14, P = 0.003) were associated with time to first re-hospitalization in multivariate analyses.Early CD-related hospitalization(within the year of diagnosis) was independently associated with need for immunosuppressives(OR = 2.08, P = 0.001) and need for surgeries(OR = 7.25, P < 0.001) during the disease course.CONCLUSION: Hospitalization and re-hospitalization rates are still high in this cohort, especially during the first-year after the diagnosis. Non-inflammatory disease behavior at diagnosis was identified as the pivotal predictive factor of both hospitalization and rehospitalization.Petra A Golovics Laszlo Lakatos Michael D Mandel Barbara D Lovasz Zsuzsanna Vegh Zsuzsanna Kurti Istvan Szita Lajos S Kiss Tunde Pandur Peter L Lakatos 2015World Journal of Gastroenterology2015,21,23:2
