2到用结构化的问询表的口头的抗病毒的肝炎 B 治疗的坚持的评估显示文摘 AIM:To assess adherence rates to nucleos(t)ide analogues(NUCs) therapy in patients with chronic hepatitis B virus infection and determine factors associated with adherence.METHODS:The questionnaire study was conducted in the liver clinics at Concord Repatriation General Hospital.All patients who were currently taking one or more NUCs were asked to complete a structured,selfadministered 32-item questionnaire.Adherence was measured using visual analogue scales.The patient’s treating clinician was also asked to assess their patient’s adherence via a structured questionnaire.RESULTS:A total of 80 patients completed the questionnaire.Sixty six percent of the patients(n = 49) reported optimal adherence whilst 25(33.8%) graded their adherence to NUCs as suboptimal.Thirty four(43%) patients reported to have omitted taking their NUCs sometime in the past.Recent non-adherence was uncommon.Amongst the patients who reported skipping medications,the most common reason cited was 'forgetfulness'(n = 27,56.25%).Other common reasons included:ran out of medications(n = 5,10.42%),being too busy(n = 4,8.33%) and due to a change in daily routine(n = 5,10.42%).Patients who reported low adherence to other prescription pills were also more likely to miss taking NUCs(P = 0.04).Patients who were under the care of a language-discordant clinician were also more likely to report suboptimal adherence to NUCs(P = 0.04).CONCLUSION:Adherence rates were much less than that expected by the physician and has potential adverse affect on long term outcome.Communication and education appear central and strategies need to be implemented to improve ongoing adherence.Leesa Giang Christian P Selinger Alice Unah Lee 2012World Journal of Hepatology2012,4,2:16
3Identification of squamous cell carcinoma associated proteins by proteomics and loss of beta tropomyosin expression in esophageal cancer显示文摘AIM: To assess the proteome of normal versus tumor tissue in squamous cell carcinoma of the esophagus (SCCE) in Iranian patients and compare our results with former reports by using proteomics. METHODS: Protein was extracted from normal and tumor tissues. Two dimensional electrophoresis was carried out and spots with differential expression were identified with mass spectrometry. RNA extraction and RT-PCR along with immunodetection were performed. RESULTS: Fourteen proteins were found whose expression levels differed in tumor compared to normal tissues. Mass spectrometric analysis resulted in the identification of β-tropomyosin (TMβ), myosin light chain 2 (and its isoform), myosin regulatory light chain 2, peroxyredoxin 2, annexinⅠand an unknown polypeptide as the down regulated polypeptides in tumor tissue. Heat shock protein 70 (HSP70), TPM4-ALK fusion oncoprotein 2, myosin light polypeptide 6, keratinⅠ, GH16431p and calreticulin were the up-regulated polypeptides found in tumor tissue. Several of these proteins, such as TMβ,HSP70, annexinⅠ, calreticulin, TPM4-ALK and isoforms of myosins, have been well recognized in tumorigenesis of esophageal or other types of cancers. CONCLUSION: Our study not only supports the involve- ment of some of the formerly reported proteins in SCCE but also introduces additional proteins found to be lost in SCCE, including TMβ.Ferdous Rastgar Jazii Zahra Najafi Reza Malekzadeh Thomas P Conrads Abed Ali Ziaee Christian Abnet Mansour Yazdznbod Ali Asghar Karkhane Ghasem H Salekdeh 2006World Journal of Gastroenterology2006,12,44:14
4Spontaneous bacterial peritonitis: The clinical challenge of a leaky gut and a cirrhotic liver显示文摘Spontaneous bacterial peritonitis(SBP) is a frequent, life-threatening bacterial infection in patients with liver cirrhosis and ascites. Portal hypertension leads to increased bacterial translocation from the intestine. Failure to eliminate invading pathogens due to immune defects associated with advanced liver disease on the background of genetic predisposition may result in SBP. The efficacy of antibiotic treatment and prophylaxis has declined due to the spread of multi-resistant bacteria. Patients with nosocomial SBP and with prior antibiotictreatment are at a particularly high risk for infection with resistant bacteria. Therefore, it is important to adapt empirical treatment to these risk factors and to the local resistance profile. Rifaximin, an oral, nonabsorbable antibiotic, has been proposed to prevent SBP, but may be useful only in a subset of patients. Since novel antibiotic classes are lacking, we have to develop prophylactic strategies which do not induce bacterial resistance. Farnesoid X receptor agonists may be a candidate, but so far, clinical studies are not available. New diagnostic tests which can be carried out quickly at the patient's site and provide additional prognostic information would be helpful. Furthermore, we need tools to predict antibiotic resistance in order to tailor first-line antibiotic treatment of spontaneous bacterial peritonitis to the individual patient and to reduce mortality.Philipp Lutz Hans Dieter Nischalke Christian P Strassburg Ulrich Spengler 2015World Journal of Hepatology2015,7,3:12
5Intentional ingestions of foreign objects among prisoners: A review显示文摘The intentional ingestion of foreign objects(IIFO) is described more commonly in prison populations than in the general population, with an estimated annual incidence of 1 in 1900 inmates in our state correctional facilities. Incidents often involve ingestion of small metal objects(e.g., paperclips, razor blades) or other commonly available items like pens or eating utensils. Despite ingestion of relatively sharp objects, most episodes can be clinically managed with either observation or endoscopy. Surgery should be reserved for those with signs or symptoms of gastrointestinal perforation or obstruction. For those with a history of IIFO, efforts should focus on prevention of recurrenceas subsequent episodes are associated with higher morbidity, significant healthcare and security costs. The pattern of IIFO is often repetitive, with escalation both in frequency of ingestions and in number of items ingested. Little is known about successful prevention strategies, but efforts to monitor patients and provide psychiatric care are potential best-practice strategies. This article aims to provide state-of-the art review on the topic, followed by a set of basic recommendations.David C Evans Thomas R Wojda Christian D Jones Andrew J Otey Stanislaw P Stawicki 2015World Journal of Gastrointestinal Endoscopy2015,7,3:10
6Vitamin D deficiency and hepatitis viruses-associated liver diseases:a literature review显示文摘The secosteroid hormone vitamin D has, in addition to its effects in bone metabolism also functions in the modulation of immune responses against infectious agents and in inhibiting tumorigenesis. Thus, deficiency of vitamin D is associated with several malignancies, but also with a plethora of infectious diseases. Among other communicable diseases, vitamin D deficiency is involved in the pathogenesis of chronic liver diseases caused by hepatitis B and C viruses(HBV, HCV) and high prevalence of vitamin D deficiency with serum levels below 20 mg/mL in patients with HBV and HCV infection are found worldwide. Several studies have assessed the effects of vitamin D supplementation on the sustained virological response(SVR) to interferon(IFN) plus ribavirin(RBV) therapy in HBV and HCV infection. In these studies, inconsistent results were reported. This review addresses general aspects of vitamin D deficiency and, in particular, the significance of vitamin D hypovitaminosis in the outcome of HBVand HCV-related chronic liver diseases. Furthermore,current literature was reviewed in order to understand the effects of vitamin D supplementation in combination with IFN-based therapy on the virological response in HBV and HCV infected patients.Nghiem Xuan Hoan Hoang Van Tong Le Huu Song Christian G Meyer Thirumalaisamy P Velavan 2018World Journal of Gastroenterology2018,24,4:9
7Genetic variants of interferon regulatory factor 5 associated with chronic hepatitis B infection显示文摘AIM To investigate possible effects of IRF5 polymorphisms in the 3' UTR region of the IFR5 locus on susceptibilityto hepatitis B virus(HBV) infection and progression of liver diseases among clinically classified Vietnamese patients.METHODS Four IFR5 SNPs(rs13242262 A/T, rs77416878 C/T, rs10488630 A/G, and rs2280714 T/C) were genotyped in clinically classified HBV patients [chronic hepatitis B(CHB). n = 99; liver cirrhosis(LC), n = 131; hepatocellular carcinoma(HCC), n = 149] and in 242 healthy controls by direct sequencing and Taq Man realtime PCR assays. RESULTS Comparing patients and controls, no significant association was observed for the four IFR5 variants. However, the alleles rs13242262 T and rs10488630 G contributed to an increased risk of liver cirrhosis(LC vs CHB: OR = 1.5, 95%CI: 1.1-2.3, adjusted P = 0.04; LC vs CHB: OR = 1.7, 95%CI: 1.1-2.6, adjusted P = 0.019). Haplotype IRF5*TCGT constructed from 4 SNPs was observed frequently in LC compared to CHB patients(OR = 2.1, 95%CI: 1.2-3.3, adjusted P = 0.008). Haplotype IRF5*TCAT occurred rather among CHB patients than in the other HBV patient groups(LC vs CHB: OR = 0.4, 95%CI: 0.2-0.8, adjusted P = 0.03; HCC vs CHB: OR = 0.3, 95%CI: 0.15-0.7, adjusted P = 0.003). The IRF5*TCAT haplotype was also associated with increased levels of ALT, AST and bilirubin. CONCLUSION Our study shows that IFR5 variants may contribute as a host factor in determining the pathogenesis in chronic HBV infections.Bui Tien Sy Nghiem Xuan Hoan Hoang Van Tong Christian G Meyer Nguyen Linh Toan Le Huu Song Claus-Thomas Bock Thirumalaisamy P Velavan 2018World Journal of Gastroenterology2018,24,2:9
8Are hyoliths Palaeozoic lophophorates?显示文摘The phylogenetic position of hyoliths has long been unsettled,with recent discoveries of a tentaculate feeding apparatus('lophophore')and fleshy apical extensions from the shell('pedicle')suggesting a lophophorate affinity.Here,we describe the first soft parts associated with the feeding apparatus of an orthothecid hyolith,Triplicatella opimus from the Chengjiang biota of South China.The tuft-like arrangement of the tentacles of T.opimus differs from that of hyolithids:suggesting they collected food directly from the substrate.A reassessment of the feeding organ in hyolithids indicates that it does not represent a lophophore and our analysis of the apical structures associated with some orthothecids show that these represent crushed portions of the shell and are not comparable to the brachiopod pedicle.The new information suggests that hyoliths are more likely to be basal members of the lophotrochozoans rather than lophophorates closely linked with the Phylum Brachiopoda.Fan Liu Christian B Skovsted Timothy P Topper Zhifei Zhang Degan Shu 2020National Science Review2020,7,2:5
9Pregnancy and inflammatory bowel disease: Do we provide enough patient education? A British study of 1324 women显示文摘AIM To examine patient knowledge and factors influencing knowledge about pregnancy in British women with inflammatory bowel disease(IBD).METHODS This is a post hoc analysis of a study of female members of Crohn's and Colitis United Kingdom, aged 18-45 years who were sent an online questionnaire recording patient demographics, education, employment, marital status, and disease characteristics. Disease related pregnancy knowledge was recorded using Crohn's and colitis pregnancy knowledge score(CCPKnow).RESULTS Of 1324 responders, 776(59%) suffered from Crohn's disease, 496(38%) from ulcerative colitis and 52(4%) from IBD-uncategorised. CCPKnow scores were poor(0-7) in 50.8%, adequate(8-10) in 23.6%, good(11-13) in 17.7% and very good(≥ 14) in 7.8%. Multiple linear regression analysis revealed that higher CCPKnow scores were independently associated with higher educational achievement(P < 0.001), younger age at diagnosis(P = 0.003) and having consulted a health care professional about pregnancy and IBD(P = 0.001). CONCLUSION Knowledge was poor in 50%. Speaking with healthcare professionals was a modifiable factor associated with better knowledge. This illustrates the importance of disease related pregnancyIsabel Carbery Jihane Ghorayeb Anna Madill Christian P Selinger 2016World Journal of Gastroenterology2016,22,36:4
10Role of interleukin-1 and its antagonism of hepatic stellate cell proliferation and liver fibrosis in the Abcb4^(-/-) mouse model显示文摘AIM: To study the interleukin-1(IL-1) pathway as a therapeutic target for liver fibrosis in vitro and in vivo using the ATP-binding cassette transporter b4^(-/-)(Abcb4^(-/-)) mouse model.METHODS: Female and male Abcb4^(-/-) mice from 6 to 13 mo of age were analysed for the degree of cholestasis(liver serum tests), extent of liver fibrosis(hydroxyproline content and Sirius red staining) and tissue-specific activation of signalling pathways such as the IL-1 pathway [quantitative polymerase chain reaction(q PCR)]. For in vivo experiments, murine hepatic stellate cells(HSCs) were isolated via pronasecollagenase perfusion followed by density gradient centrifugation using female mice. Murine HSCs were stimulated with up to 1 ng/m L IL-1β with or without 2.5 μg/m L Anakinra, an IL-1 receptor antagonist, respectively. The proliferation of murine HSCs was assessed via the Brd U assay. The toxicity of Anakinra was evaluated via the fluorescein diacetate hydrolysis(FDH) assay. In vivo 8-wk-old Abcb4^(-/-) mice with an already fully established hepatic phenotype were treated with Anakinra(1 mg/kg body-weight daily intraperitoneally) or vehicle and liver injury and liver fibrosis were evaluated via serum tests, q PCR, hydroxyproline content and Sirius red staining. RESULTS: Liver fibrosis was less pronounced in males than in female Abcb4^(-/-) animals as defined by a lower hydroxyproline content(274 ± 64 μg/g vs 436 ± 80 μg/g liver, respectively; n = 13-15; P < 0.001; MannWhitney U-test) and lower m RNA expression of the profibrogenic tissue inhibitor of metalloproteinase-1(TIMP)(1 ± 0.41 vs 0.66 ± 0.33 fold, respectively; n = 13-15; P < 0.05; Mann-Whitney U-test). Reduced liver fibrosis was associated with significantly lower levels of F4/80 m RNA expression(1 ± 0.28 vs 0.71 ± 0.41 fold, respectively; n = 12-15; P < 0.05; Mann-Whitney U-test) and significantly lower IL-1β m RNA expression levels(1 ± 0.38 vs 0.44 ± 0.26 fold, respectively; n = 13-15; P < 0.001; Mann-Whitney U-test). No gender differences in the serum liver parameters [bilirubin; alanine aminotransferase(ALT); aspartate aminotransferase and alkaline phosphatase(AP)] were found. In vitro, the administration of IL-1β resulted in a significant increase in HSC proliferation [0.94 ± 0.72 arbitrary units(A.U.) in untreated controls, 1.12 ± 0.80 A.U. at an IL-1β concentration of 0.1 ng/m L and 1.18 ± 0.73 A.U. at an IL-1β concentration of 1 ng/m L in samples from n = 6 donor animals; P < 0.001; analyses of variance(ANOVA)]. Proliferation was reduced significantly by the addition of 2.5 μg/m L Anakinra(0.81 ± 0.60 A.U. in untreated controls, 0.92 ± 0.68 A.U. at an IL-1β concentration of 0.1 ng/m L, and 0.91 ± 0.69 A.U. at an IL-1β concentration of 1 ng/m L; in samples from n = 6 donor animals; P < 0.001; ANOVA) suggesting an anti-proliferative effect of this clinically approved IL-1 receptor antagonist. The FDH assay showed this dose to be non-toxic in HSCs. In vivo, Anakinra had no effect on the hepatic hydroxyprolinecontent, liver serum tests(ALT and AP) and profibrotic(collagen 1α1, collagen 1α2, transforming growth factor-β, and TIMP-1) and anti-fibrotic [matrix metalloproteinase 2(MMP2), MMP9 and MMP13 ] gene expression after 4 wk of treatment. Furthermore, the hepatic IL-1β and F4/80 m RNA expression levels were unaffected by Anakinra treatment.CONCLUSION: IL-1β expression is associated with the degree of liver fibrosis in Abcb4^(-/-) mice and promotes HSC proliferation. IL-1 antagonism shows antifibrotic effects in vitro but not in Abcb4^(-/-) mice.Florian P Reiter Ralf Wimmer Lena Wottke Renate Artmann Jutta M Nagel Manuel O Carranza Doris Mayr Christian Rust Peter Fickert Michael Trauner Alexander L Gerbes Simon Hohenester Gerald U Denk 2016World Journal of Hepatology2016,8,8:3
11Hepatic encephalopathy before and neurological complications after liver transplantation have no impact on the employment status 1 year after transplantation显示文摘AIM To investigate the impact of hepatic encephalopathybefore orthotopic liver transplantation(OLT) and neurological complications after OLT on employment after OLT.METHODS One hundred and fourteen patients with chronic liver disease aged 18-60 years underwent neurological examination to identify neurological complications, neuropsychological tests comprising the PSE-SyndromeTest yielding the psychometric hepatic encephalopathy score, the critical flicker frequency and the Repeatable Battery for the Assessment of Neuropsychological Status(RBANS), completed a questionnaire concerning their occupation and filled in the short form 36(SF-36) to assess health-related quality of life before OLT and 12 mo after OLT, if possible. Sixty-eight(59.6%) patients were recruited before OLT, while on the waiting list for OLT at Hannover Medical School [age: 48.7 ± 10.2 years, 45(66.2%) male], and 46(40.4%) patients were included directly after OLT. RESULTS Before OLT 43.0% of the patients were employed. The patients not employed before OLT were more often non-academics(employed: Academic/non-academic 16(34.0%)/31 vs not employed 10(17.6%)/52, P = 0.04), had more frequently a history of hepatic encephalopathy(HE)(yes/no; employed 15(30.6%)/34 vs not employed 32(49.2%)/33, P = 0.05) and achieved worse results in psychometric tests(RBANS sum score mean ± SD employed 472.1 ± 44.5 vs not employed 443.1 ± 56.7, P = 0.04) than those employed. Ten patients(18.2%), who were not employed before OLT, resumed work afterwards. The patients employed after OLT were younger [age median(range, min-max) employed 47(42, 18-60) vs not employed 50(31, 29-60), P = 0.01], achieved better results in the psychometric tests(RBANS sum score mean ± SD employed 490.7 ± 48.2 vs not employed 461.0 ± 54.5, P = 0.02) and had a higher health-related quality of life(SF 36 sum score mean ± SD employed 627.0 ± 138.1 vs not employed 433.7 ± 160.8; P < 0.001) compared to patients not employed after OLT. Employment before OLT(P < 0.001), age(P < 0.01) and SF-36 sum score 12 mo after OLT(P < 0.01) but not HE before OLT or neurological complications after OLT were independent predictors of the employment status after OLT.CONCLUSION HE before and neurological complications after OLT have no impact on the employment status 12 mo after OLT. Instead younger age and employment before OLT predict employment one year after OLT.Henning Pflugrad Anita B Tryc Annemarie Goldbecker Christian P Strassburg Hannelore Barg-Hock Jürgen Klempnauer Karin Weissenborn 2017World Journal of Hepatology2017,9,10:3

15Near-infrared fluorescence guided esophageal reconstructive surgery: A systematic review显示文摘BACKGROUND After an esophagectomy, the stomach is most commonly used to restore continuity of the upper gastrointestinal tract. These esophago-gastric anastomoses are prone to serious complications such as leakage associated with high morbidity and mortality. Graft perfusion is considered to be an important predictor for anastomotic integrity. Based on the current literature we believe Indocyanine green fluorescence angiography(ICGA) is an easy assessment tool for gastric tube(GT) perfusion, and it might predict anastomotic leakage(AL).AIM To evaluate feasibility and effectiveness of ICGA in GT perfusion assessment and as a predictor of AL.METHODS This study was designed according to the PRISMA guidelines and registered in the PROSPERO database. PubMed and EMBASE were independently searched by 2 reviewers for studies presenting data on intraoperative ICGA GT perfusion assessment during esophago-gastric reconstruction after esophagectomy.Relevant outcomes such as feasibility, complications, intraoperative surgical changes based on ICGA findings, quantification attempts, anatomical data and the impact of ICGA on postoperative anastomotic complications, were collected by 2 independent researchers. The quality of the included articles was assessed based on the Methodological Index for Non-Randomized Studies. The 19 included studies presented data on 1192 esophagectomy patients, in 758 patients ICGA was used perioperative to guide esophageal reconstruction.RESULTS The 19 included studies for qualitative analyses all described ICGA as a safe and easy method to evaluate gastric graft perfusion. AL occurred in 13.8% of the entire cohort, 10% in the ICG guided group and 20.6% in the control group(P <0.001). When poorly perfused cases are excluded from the analyses, the difference in AL was even larger(AL well-perfused group 6.3% vs control group 20.5%, P <0.001). The AL rate in the group with an altered surgical plan based on the ICG image was 6.5%, similar to the well perfused group(6.3%) and significantly less than the poorly perfused group(47.8%)(P < 0.001), suggesting that the technique is able to identify and alter a potential bad outcome.CONCLUSION ICGA is a safe, feasible and promising method for perfusion assessment. The lower AL rate in the well perfused group suggest that a good fluorescent signal predicts a good outcome.Elke Van Daele Yves Van Nieuwenhove Wim Ceelen Christian Vanhove Bart P Braeckman Anne Hoorens Jurgen Van Limmen Oswald Varin Dirk Van de Putte Wouter Willaert Piet Pattyn 2019World Journal of Gastrointestinal Oncology2019,11,3:3

19Pregnancy related issues in inflammatory bowel disease: Evidence base and patients' perspective显示文摘Inflammatory bowel disease (IBD) affects women of childbearing age and can influence fertility, pregnancy and decisions regarding breastfeeding. Women with IBD need to consider the possible course of disease during pregnancy, the benefits and risks associated with medications required for disease management during pregnancy and breastfeeding and the effects of mode of delivery on their disease. When indicated, aminosalicylates and thiopurines can be safely used during pregnancy. Infliximab and Adalimumab are considered probably safe during the first two trimesters. During the third trimester the placenta can be crossed and caution should be applied. Methotrexate is associated with severe teratogenicity due to its folate antagonism and is strictly contraindicated. Women with IBD tend to deliver earlier than healthy women, but can have a vaginal delivery in most cases. Caesarean sections are generally recommended for women with active perianal disease or after ileo-anal pouch surgery. While the impact of disease activity and medication has been addressed in several studies, there are minimal studies evaluating patients' perspective on these issues. Women's attitudes may influence their decision to have children and can positively or negatively influence the chance of conceiving, and their beliefs regarding therapies may impact on the course of their disease during pregnancy and/or breastfeeding. This review article outlines the impact of IBD and its treatment on pregnancy, and examines the available data on patients' views on this subject.Christian P Selinger Rupert WL Leong Simon Lal 2012World Journal of Gastroenterology2012,18,21:2
