1Assessment of drug-induced hepatotoxicity in clinical practice: A challenge for gastroenterologists显示文摘Currently, pharmaceutical preparations are serious contributors to liver disease; hepatotoxicity ranking as the most frequent cause for acute liver failure and post-commercialization regulatory decisions. The diagnosis of hepatotoxicity remains a difficult task because of the lack of reliable markers for use in general clinical practice. To incriminate any given drug in an episode of liver dysfunction is a step-by-step process that requires a high degree of suspicion, compatible chronology, awareness of the drug’s hepatotoxic potential, the exclusion of alternative causes of liver damage and the ability to detect the presence of subtle data that favors a toxic etiology. This process is time-consuming and the final result is frequently inaccurate. Diagnostic algorithms may add consistency to the diagnostic process by translating the suspicion into a quantitative score. Such scales are useful since they provide a framework that emphasizes the features that merit attention in cases of suspected hepatic adverse reaction as well. Current efforts in collecting bona fide cases of drug-induced hepatotoxicity will make refinements of existing scales feasible. It is now relatively easy to accommodate relevant data within the scoring system and to delete low-impact items. Efforts should also be directed toward the development of an abridged instrument for use in evaluating suspected drug-induced hepatotoxicity at the very beginning of the diagnosis and treatment process when clinical decisions need to be made. The instrument chosen would enable a confident diagnosis to be made on admission of the patient and treatment to be fine-tuned as further information is collected.Raúl J Andrade Mercedes Robles Alejandra Fernández-Castaer Susana López-Ortega M Carmen López-Vega M Isabel Lucena 2007World Journal of Gastroenterology2007,13,3:18
2drug-induced autoimmune liver disease:a diagnostic dilemma of an increasingly reported disease显示文摘The aetiology of autoimmune hepatitis(AIH) is uncer-tain but the disease can be triggered in susceptible patients by external factors such as viruses or drugs.AIH usually develops in individuals with a genetic back-ground mainly consisting of some risk alleles of the major histocompatibility complex(HLA).Many drugs have been linked to AIH phenotypes,which sometimes persist after drug discontinuation,suggesting that they awaken latent autoimmunity.At least three clini-cal scenarios have been proposed that refers to drug- induced autoimmune liver disease(DIAILD):AIH with drug-induced liver injury(DILI); drug induced-AIH(DI-AIH); and immune mediated DILI(IM-DILI).In addi-tion,there are instances showing mixed features of DI-AIH and IM-DILI,as well as DILI cases with positive autoantibodies.Histologically distinguishing DILI from AIH remains a challenge.Even more challenging is the differentiation of AIH from DI-AIH mainly relying in histological features; however,a detailed standard-ised histologic evaluation of large cohorts of AIH and DI-AIH patients would probably render more subtle features that could be of help in the differential diag-nosis between both entities.Growing information on the relationship of drugs and AIH is being available,being drugs like statins and biologic agents more fre-quently involved in cases of DIAILD.In addition,there is some evidence on the fact that patients diagnosed with DIAILD may have had a previous episode of hepa-totoxicity.Further collaborative studies in DIAILD will strengthen the knowledge and understanding of this intriguing and complex disorder which might represent different phenotypes across the spectrum ofAgustin Castiella Eva Zapata M Isabel Lucena Raúl J Andrade 2014World Journal of Hepatology2014,6,4:13
3Boosting third-harmonic generation by a mirror-enhanced anapole resonator显示文摘We demonstrate that a dielectric anapole resonator on a metallic mirror can enhance the third harmonic emission by two orders of magnitude compared to a typical anapole resonator on an insulator substrate.By employing a gold mirror under a silicon nanodisk,we introduce a novel characteristic of the anapole mode through the spatial overlap of resonantly excited Cartesian electric and toroidal dipole modes.This is a remarkable improvement on the early demonstrations of the anapole mode in which the electric and toroidal modes interfere off-resonantly.Therefore,our system produces a significant near-field enhancement,facilitating the nonlinear process.Moreover,the mirror surface boosts the nonlinear emission via the free-charge oscillations within the interface,equivalent to producing a mirror image of the nonlinear source and the pump beneath the interface.We found that these improvements result in an extremely high experimentally obtained efficiency of 0.01%.Lei Xu Mohsen Rahmani Khosro Zangeneh Kamali Aristeidis Lamprianidis Lavinia Ghirardini Jürgen Sautter Rocio Camacho-Morales Haitao Chen Matthew Parry Isabelle Staude Guoquan Zhang Dragomir Neshev Andrey E.Miroshnichenko 2018Light(Science & Applications)2018,7,1:5
4Management of digestive bleeding related to portal hypertension in cirrhotic patients:A French multicenter cross-sectional practice survey显示文摘AIM: To investigate the conformity of management practices of gastrointestinal hemorrhage in cirrhotic patients with relevant guidelines. METHODS: A questionnaire on the management of digestive bleeding was completed for all consecutive cirrhotic patients admitted to 31 French hospitals. RESULTS: One hundred and twenty-six bleeding events were recorded. It was the first bleeding episode in 79 patients (63%), of whom 40 (51%) had a prior diagnosis of cirrhosis and 25 (32%) had previously undergone an endoscopy. The bleeding episode was a recurrence in 46 patients (37%). The median time between onset and admission was 4 h, but exceeded 12 h in 42% of cases. There was an agreement between centers forearly vasoactive drug administration (87% of cases), association with ligation (42%) more often than sclerosis (21%) at initial endoscopy, and antibiotic prophylaxis (64%). By contrast, prescription of beta-blockade alone or in combination (0 to 100%, P = 0.003) for secondary prophylaxis and lactulose (26% to 86%, P = 0.04), differed among centers. CONCLUSION: In French hospitals, management of bleeding related to portal hypertension in cirrhotic patients is generally in keeping with the consensus. Broad variability still remains concerning beta-blockade use for secondary prophylaxis. Screening for esophageal varices, the use of antibiotic prophylaxis and patients information need to be improved.Pierre Ingrand Jérme Gournay Pierre Bernard Frédéric Oberti Brigitte Bernard-Chabert Arnault Pauwels Philippe Renard Eric Bartoli Jean-Franois Cadranel Jean-Claude Barbare Isabelle Ingrand Michel Beauchant 2006World Journal of Gastroenterology2006,12,48:4
5Analysis of the human Atox 1 homologue in Wilson patients显示文摘AIM: To analyze the metallochaperone antioxidant-1 (Atox1) gene sequence in Wilson disease patients. METHODS: Mutation analysis of the four exons of the Atox1 gene including the intron- exon boundaries was performed in 63 Wilson disease patients by direct sequencing. RESULTS: From 63 selected patients no mutations were identified after the entire coding region including the intron- exon boundaries of Atox1 were sequenced. One known polymorphism within the Atox1 gene (5’UTR -99 T>C) in 31 (49%) of the Wilson patients as well as one previously undescribed variation (5’UTR -68 C>T) in 2 of the Wilson patients could be detected. Statistical analyses revealed that the existence of a variation within the Atox1- gene showed a tendency towards an earlier onset of the disease. CONCLUSION: Based on the data of this study, no major role can be attributed to Atox1 in the pathophysiology or clinical variation of Wilson disease.Isabel Simon Mark Schaefer Jürgen Reichert Wolfgang Stremmel 2008World Journal of Gastroenterology2008,14,15:4
6Characterization of two rat models of cystic fibrosis—KO and F508del CFTR—Generated by Crispr-Cas9显示文摘Background: Genetically engineered animals are essential for gaining a proper understanding of the disease mechanisms of cystic fibrosis(CF). The rat is a relevant laboratory model for CF because of its zootechnical capacity, size, and airway characteristics, including the presence of submucosal glands.Methods: We describe the generation of a CF rat model(F508 del) homozygous for the p.Phe508 del mutation in the transmembrane conductance regulator(Cftr) gene. This model was compared to new Cftr-/-rats(CFTR KO). Target organs in CF were examined by histological staining of tissue sections and tooth enamel was quantified by micro-computed tomography. The activity of CFTR was evaluated by nasal potential difference(NPD) and short-circuit current measurements. The effect of VX-809 and VX-770 was analyzed on nasal epithelial primary cell cultures from F508 del rats.Results: Both newborn F508 del and Knock out(KO) animals developed intestinal obstruction that could be partly compensated by special diet combined with an osmotic laxative. The two rat models exhibited CF phenotypic anomalies such as vas deferens agenesis and tooth enamel defects. Histology of the intestine, pancreas, liver, and lungs was normal. Absence of CFTR function in KO rats was confirmed ex vivo by short-circuit current measurements on colon mucosae and in vivo by NPD, whereas residual CFTR activity was observed in F508 del rats. Exposure of F508 del CFTR nasal primary cultures to a combination of VX-809 and VX-770 improved CFTR-mediated Cl-transport.Conclusions: The F508 del rats reproduce the phenotypes observed in CFTR KO animals and represent a novel resource to advance the development of CF therapeutics.Elise Dreano Marc Bacchetta Juliette Simonin Louise Galmiche Claire Usal Lotfi Slimani Jérémy Sadoine Laurent Tesson Ignacio Anegon Jean-Paul Concordet Aurélie Hatton Lucile Vignaud Danielle Tondelier Isabelle Sermet-Gaudelus Marc Chanson Charles-Henry Cottart 2019Animal Models and Experimental Medicine2019,2,4:3
7Multiple common garden experiments suggest lack of local adaptation in an invasive ornamental plant显示文摘Adaptive evolution along geographic gradients of climatic conditions is suggested to facilitate the spread of invasive plant species,leading to clinal variation among populations in the introduced range.We investigated whether adaptation to climate is also involved in the invasive spread of an ornamental shrub,Buddleja davidii,across western and central Europe.Methods We combined a common garden experiment,replicated in three climatically different central European regions,with reciprocal transplantation to quantify genetic differentiation in growth and reproductive traits of 20 invasive B.davidii populations.Additionally,we compared compensatory regrowth among populations after clipping of stems to simulate mechanical damage.Important Findings Our results do not provide evidence for clinal variation among invasive B.davidii populations:populations responded similarly to the different environments,and trait values were not correlated to climatic conditions or geographic coordinates of their home sites.Moreover,we did not detect differences in the compensatory ability of populations.We suppose that the invasive spread of B.davidii has been facilitated by phenotypic plasticity rather than by adaptation to climate and that continent-wide shuffling of cultivars due to horticultural trade may have limited local adaptation so far.Susan K.Ebeling Jürg Stöcklin Isabell Hensen Harald Auge 2011Journal of Plant Ecology2011,4,4:3
8Food groups, diet quality and colorectal cancer risk in the Basque Country显示文摘BACKGROUND The results obtained to date concerning food groups,diet quality and colorectal cancer(CRC)risk vary according to criteria used and the study populations.AIM To study the relationships between food groups,diet quality and CRC risk,in an adult population of the Basque Country(North of Spain).METHODS This observational study included 308 patients diagnosed with CRC and 308 ageand sex-matched subjects as controls.During recruitment,dietary,anthropometric,lifestyle,socioeconomic,demographic and health status information was collected.Adherence to the dietary recommendations was evaluated utilizing the Healthy Eating Index for the Spanish Diet and the MedDietScore.Conditional logistic regressions were used to evaluate the associations of food group intakes,diet quality scores,categorized in tertiles,with CRC risk.RESULTS The adjusted models for potential confounding factors showed a direct association between milk and dairy products consumption,in particular high-fat cheeses[odds ratio(OR)third tertile vs first tertile=1.87,95%confidence intervals(CI):1.11-3.16],and CRC risk.While the consumption of fiber-containing foods,especially whole grains(OR third tertile vs first tertile=0.62,95%CI:0.39-0.98),and fatty fish(OR third tertile vs first tertile=0.53,95%CI:0.27-0.99)was associated with a lower risk for CRC.Moreover,higher MD adherence was associated with a reduced CRC risk in adjusted models(OR third tertile vs first tertile=0.40,95%CI:0.20-0.80).CONCLUSION Direct associations were found for high-fat cheese,whereas an inverse relation was reported for fiber-containing foods and fatty fish,as well as adherence to a Mediterranean dietary pattern.Iker Alegria-Lertxundi Carmelo Aguirre Luis Bujanda Francisco J Fernandez Francisco Polo JoseMªOrdovas MªCarmen Etxezarraga Inaki Zabalza Mikel Larzabal Isabel Portillo Marian M de Pancorbo Koldo Garcia-Etxebarria Ana MªRocandio Marta Arroyo-Izaga 2020World Journal of Gastroenterology2020,26,28:3
