1Transcatheter aortic valve implantation:Current status and future perspectives显示文摘Although surgical aortic valve replacement is the standard therapy for severe aortic stenosis(AS),about one third of patients are considered inoperable due to unacceptable surgical risk.Under medical treatment alone these patients have a very poor prognosis with a mortality rate of 50%at 2 years.Transcatheter aortic valve implantation(TAVI)has been used in these patients,and has shown robust results in the only randomized clinical trial of severe AS treatment performed so far.In this review,we will focus on the two commercially available systems:Edwards SAPIEN valve and CoreValve Revalving system.Both systems have demonstrated success rates of over 90%with 30-d mortality rates below 10%in the most recent transfemoral TAVI studies.Moreover,long-term studies have shown that the valves have good haemodynamic performance.Some studies are currently exploring the non-inferiority of TAVI procedures vs conventional surgery in high-risk patients,and long-term clinical results of the percutaneous valves.In this article we review the current status of TAVI including selection of patients,a comparison of available prostheses,results and complications of the procedure,clinical outcomes,and future perspectives.Pablo Salinas Raul Moreno Jose L Lopez-Sendon 2011World Journal of Cardiology2011,3,6:5
2Prevalence of vacA, cagA and babA2 genes in Cuban Helicobacter pylori isolates显示文摘AIM: To investigate the prevalence of vacuolating cytotoxin (vacA), cytotoxin associated gene A (cagA) and blood adhesion binding antigen (babA2) genotypes of Helicobacter pylori (H pylori) isolates from Cuban dyspeptic patients. METHODS: DNA was extracted from H pylori-positive cultures taken from 130 dyspeptic patients. Genotyping was performed by PCR, using specifi c primers for vacA (s1, s2, m1, m2), cagA and babA2 genes. Endoscopic observations and histological examinations were used to determine patient pathologies. RESULTS: vacA alleles s1 , s2 , m1 and m2 were detected in 96 (73.8%), 34 (26.2%), 75 (57.7%) and 52 isolates (40%), respectively, while the cagA gene was detected in 95 isolates (73.2%). One hundred and seven isolates (82.3%) were babA2-positive. A signif icant correlation was observed between vacAs1m1 and cagA and between vacAs1m1 and babA2 genotypes (P < 0.001 and P < 0.05, respectively) and between babA2 genotype and cagA status (P < 0.05); but, no correlation was observed between vacAs1 and babA2 genotypes. Eighty fi ve (65.4%) and 73 (56.2%) strains were type 1 (vacAs1-cagA-positive) and 'triple- positive' (vacAs1-cagA-babA2-positive), respectively, and their presence was significantly associated with duodenal ulcer (P < 0.01 and P < 0.001, respectively). CONCLUSION: The distribution of the main virulence factors in the Cuban strains in this study resembled that of the Western-type strains, and the more virulent H pylori isolates were signifi cantly associated with duodenal ulcer, ulcer disease being the worst pathology observed in the group studied.Lino E Torres Karelia Melián Arlenis Moreno Jordis Alonso Carlos A Sabatier Mayrín Hernández Ludisleydis Bermúdez Boris L Rodríguez 2009World Journal of Gastroenterology2009,15,2:4
3Celiac disease serology in patients with different pretest probabilities: Is biopsy avoidable?显示文摘AIM: To establish the diagnostic performance of sev-eral serological tests, individually and in combination, for diagnosing celiac disease (CD) in patients with different pretest probabilities, and to explore potential se- rological algorithms to reduce the necessity for biopsy. METHODS: We prospectively performed duodenal biopsy and serology in 679 adults who had either high risk (n = 161) or low risk (n = 518) for CD. Blood samples were tested using six assays (enzyme-linked immunosorbent assay) that detected antibodies to tissue transglutaminase (tTG) and deamidated gliadin peptide (DGP). RESULTS: CD prevalence was 39.1% in the high-risk population and 3.3% in the low-risk group. In high-risk patients, all individual assays had a high diagnostic efficacy [area under receiving operator characteristic curves (AU ROC): 0.968 to 0.999]. In contrast, assays had a lower diagnostic efficacy (AU ROC: 0.835 to 0.972) in the low-risk group. Using assay combinations, it would be possible to reach or rule out diagnosis of CD without biopsy in 92% of cases in both pretest populations. We observed that the new DGP/tTG Screen assay resulted in a surplus compared to more conventional assays in any clinical situation. CONCLUSION: The DGP/tTG Screen assay could be considered as the best initial test for CD. Combinations of two tests, including a DGP/tTG Screen, might be able to diagnose CD accurately in different clinical scenarios making biopsy avoidable in a high proportion of subjects.Emilia Sugai María L Moreno Hui J Hwang Ana Cabanne Adriana Crivelli Fabio Nach-man Horacio Vázquez Sonia Niveloni Julio Argonz Roberto Mazure Graciela La Motta María E Caniggia Edgardo Smecuol Néstor Chopita Juan C Gómez Eduardo Maurińo Julio C Bai 2010World Journal of Gastroenterology2010,16,25:4
4Inflammatory bowel disease: A descriptive study of 716 local Chilean patients显示文摘AIM: To demographically and clinically characterize inflammatory bowel disease(IBD) from the local registry and update data previously published by our group.METHODS: A descriptive study of a cohort based on a registry of patients aged 15 years or older who were diagnosed with IBD and attended the IBD program at Clínica Las Condes in Santiago, Chile. The registry was created in April 2012 and includes patients registered up to October 2015. The information was anonymously downloaded in a monthly report, and the information on patients with more than one visit was updated. The registry includes demographic, clinical and disease characteristics, including the Montreal Classification, medical treatment, surgeries and hospitalizations for crisis. Data regarding infection with Clostridium difficile(C. difficile) were incorporated in the registry in 2014. Data for patients who received consultations as second opinions and continued treatment at this institution were also analyzed. RESULTS: The study included 716 patients with IBD: 508 patients(71%) were diagnosed with ulcerative colitis(UC), 196 patients(27%) were diagnosed with Crohn's disease(CD) and 12 patients(2%) were diagnosed with unclassifiable IBD. The UC/CD ratio was 2.6/1. The median age was 36 years(range 16-88), and 58% of the patients were female, with a median age at diagnosis of 29 years(range 5-76). In the past 15 years, a sustained increase in the number of patients diagnosed with IBD was observed, where 87% of the patients were diagnosed between the years 2001 and 2015. In the cohort examined in the present study, extensive colitis(50%) and colonic involvement(44%) predominated in the patients with UC and CD, respectively. In CD patients, nonstricturing/non-penetrating behavior was more frequent(80%), and perianal disease was observed in 28% of the patients. There were significant differences in treatment between UC and CD, with a higher use of corticosteroids, and immunosuppressive and biological therapies was observed in the patients with CD(P < 0.05 and P < 0.01). Significant surgical differences were also observed: 5% of the UC patients underwent surgery, whereas 38% of the CD patients required at least one surgery(P < 0.01). The patients with CD were hospitalized more often during their disease course than the patients with UC(55% and 35% of the patients, respectively; P < 0.01). C. difficile infection was acquired by 5% of the patients in each group at some point during the disease course. Nearly half of the patients consulted at the institution for a second opinion, and 32% of these individuals continued treatment at the institution. CONCLUSION: IBD has continued to increase in the study cohort, slowly approaching the level reported in developed countries.Daniela Simian Daniela Fluxá Lilian Flores Jaime Lubascher Patricio Ibánez Carolina Figueroa Udo Kronberg Raúl Acuna Mauricio Moreno Rodrigo Quera 2016World Journal of Gastroenterology2016,22,22:2
5Use of agents stimulating erythropoiesis in digestive diseases显示文摘Anemia is the most common complication of inflammatory bowel disease (IBD). Control and inadequate treatment leads to a worse quality of life and increased morbidity and hospitalization. Blood loss, and to a lesser extent, malabsorption of iron are the main causes of iron def iciency in IBD. There is also a variable component of anemia related to chronic inflammation. The anemia of chronic renal failure has been treated for many years with recombinant human erythropoietin (rHuEPO), which significantly improves quality of life and survival. Subsequently, rHuEPO has been used progressively in other conditions that occur with anemia of chronic processes such as cancer, rheumatoid arthritis or IBD, and anemia associated with the treatment of hepatitis C virus. Erythropoietic agents complete the range of available therapeutic options for treatment of anemia associated with IBD, which begins by treating the basis of the inflammatory disease, along with intravenous iron therapy as f irst choice. In cases of resistance to treatment with iron, combined therapy with erythropoietic agents aims to achieve near-normal levels of hemoglobin/hematocrit (11-12 g/dL). New formulations of intravenous iron (iron carboxymaltose) and the new generation of erythropoietic agents (darbepoetin and continuous erythropoietin receptor activator) will allow better dosing with the same eff icacy and safety.Rosario Moreno López Beatriz Sicilia Aladrén Fernando Gomollón García 2009World Journal of Gastroenterology2009,15,37:2
6Chronic pelvic pain,psychiatric disorders and early emotional traumas:Results of a cross sectional case-control study显示文摘AIM To compare the prevalence of psychiatric disorders and early emotional traumas between women with chronic pelvic pain(CPP) and healthy women.METHODS One hundred women in reproductive age,50 of them had CPP(according to the criteria set by the International Association for Study of Pain),and 50 were considered healthy after the gynecological evaluation.The eligibility criteria were defined as follows:chronic or persistent pain perceived in the pelvis-related structures(digestive,urinary,genital,myofascial or neurological systems).Only women in reproductive age with acyclic pain for 6 mo,or more,were included in the present study.Menopause was the exclusion criterion.The participants were grouped according to age,school level and socioeconomic status and were individually assessed through DSM-IV Structured Clinical Interview(SCID-I) and Early Trauma Inventory Self-report-short form(ETISR-SF Brazilian version).Descriptive statistics,group comparison tests and multivariate logistics regression were used in the data analysis.RESULTS The early emotional traumas are highly prevalent,but their prevalence did not differ between the two groups.The current Major Depressive Disorder was more prevalent in women with CPP.The CPP was associatedwith endometriosis in 48% of the women.There was no difference in the prevalence of disorders when endometriosis was taken into account(endometriosis vs other diseases:P > 0.29).The current Major Depressive Disorder and the Bipolar Disorder had greater occurrence likelihood in the group of women with CPP(ODDS = 5.25 and 9.0).CONCLUSION The data reinforce the link between mood disorders and CPP.The preview evidences about the association between CPP and early traumas tended not to be significant after a stronger methodological control was implemented.Flávia L Osório Ana Carolina F Carvalho Mariana F Donadon André L Moreno Omero Polli-Neto 2016World Journal of Psychiatry2016,6,3:2

10在经历 transcatheter 的病人的 atrial 纤维性颤动的临床、预示的含意大动脉的阀门培植显示文摘 AIM: To study a cohort of consecutive patients under-going transcatheter aortic valve implantation (TAVI) and compare the outcomes of atrial fibrillation (AF) patients vs patients in sinus rhythm (SR). METHODS: All consecutive patients undergoing TAVI in our hospital were included. The AF group comprised patients in AF at the time of TAVI or with history of AF, and were compared with the SR group. Procedural, echocardiographic and follow-up variables were compared. Likewise, the CHA 2 DS 2-VASC stroke risk score and HAS-BLED bleeding risk score and antithrombotic treatment at discharge in AF patients were compared with that in SR patients. RESULTS: From a total of 34 patients undergoing TAVI, 17 (50%) were allocated to the AF group, of whom 15 (88%) were under chronic oral anticoagulation. Patients in the AF group were similar to those in the SR group except for a trend (P = 0.07) for a higher logistic EuroSCORE (28% vs 19%), and a higher prevalence of hypertension (82% vs 53%) and chronic renal failure (17% vs 0%). Risk of both stroke and bleeding was high in the AF group (mean CHA 2 DS 2-VASC 4.3, mean HAS-BLED 2.9). In the AF group, treatment at discharge included chronic oral anticoagulation in all except one case, and in association with an antiplatelet drug in 57% of patients. During a mean follow-up of 11 mo (maximum 32), there were only two strokes, none of them during the peri-procedural period: one in the AF group at 30 mo and one in the SR group at 3 mo. There were no statistical differences in procedural success, and clinical outcome (survival at 1 year 81% vs 74% in AF and SR groups, respectively, P = NS). CONCLUSION: Patients in AF undergoing TAVI show a trend to a higher surgical risk. However, in our cohort, patients in AF did not have a higher stroke rate compared to the SR group, and the prognosis was similar in both groups.Pablo Salinas Raúl Moreno Luis Calvo Santiago Jiménez-Valero Guillermo Galeote Angel Sánchez-Recalde Teresa López-Fernández Sergio Garcia-Blas Diego Iglesias Luis Riera Isidro Moreno-Gómez Jose María Mesa Ignacio Plaza Rocio Ayala Rosa Gonzalez José-Luis López-Sendón 2012World Journal of Cardiology2012,4,1:2
