| 1 | Risk factors associated with the development of ischemic colitis显示文摘AIM:To ascertain the role of cardiovascular risk factors,cardiovascular diseases,standard treatments and other diseases in the development of ischemic colitis(IC).METHODS:A retrospective,case-control study was designed,using matched data and covering 161 incident cases of IC who required admission to our hospital from 1998 through 2003.IC was diagnosed on the basis of endoscopic findings and diagnostic or compatible his-tology.Controls were randomly chosen from a cohort of patients who were admitted in the same period and required a colonoscopy,excluding those with diagnosis of colitis.Cases were matched with controls(ratio 1:2),by age and sex.A conditional logistic regression was performed.RESULTS:A total of 483 patients(161 cases,322 con-trols)were included;mean age 75.67±10.03 years,55.9%women.The principal indications for colonos-copy in the control group were lower gastrointestinal hemorrhage(35.4%),anemia(33.9%),abdominal pain(19.9%)and diarrhea(9.6%).The endoscopic findings in this group were hemorrhoids(25.5%),diverticular disease(30.4%),polyps(19.9%)and colorectal cancer(10.2%).The following variables were associated with IC in the univariate analysis:arterial hypertension(P= 0.033);dyslipidemia(P<0.001);diabetes mellitus(P =0.025);peripheral arterial disease(P=0.004);heart failure(P=0.026);treatment with hypotensive drugs(P=0.023);angiotensin-converting enzyme inhibitors;(P=0.018);calcium channel antagonists(P=0.028);and acetylsalicylic acid(ASA)(P<0.001).Finally,the following variables were independently associated with the development of IC:diabetes mellitus[odds ratio(OR)1.76,95%confidence interval(CI):1.001-3.077,P=0.046];dyslipidemia(OR 2.12,95%CI:1.26-3.57,P=0.004);heart failure(OR 3.17,95%CI:1.31-7.68,P=0.01);peripheral arterial disease(OR 4.1,95%CI:1.32-12.72,P=0.015);treatment with digoxin(digitalis)(OR 0.27,95%CI:0.084-0.857,P=0.026);and ASA(OR 1.97,95%CI:1.16-3.36,P=0.012).CONCLUSION:The development of an episode of IC was independently associated with diabetes,dyslipid-emia,presence of heart failure,peripheral arterial dis-ease and treatment with digoxin or ASA. | Joaquín Cubiella Fernández Luisa Núez Calvo Elvira González Vázquez Maria Jesús García García Maria Teresa Alves Pérez Isabel Martínez Silva Javier Fernández Seara | 2010 | World Journal of Gastroenterology2010，16，36： | 27 |
| 2 | The importance of avoiding unnecessary right ventricular pacing in clinical practice显示文摘Symptomatic bradycardia is effectively treated with the implantation of a cardiac pacemaker. Although a highly successful therapy, during recent years there has been a focus on the negative effects associated with longterm pacing of the apex of the right ventricle(RV). It has been shown in both experimental and clinical studies that RV pacing leads to ventricular dyssynchrony, similar to that of left bundle branch block, with subsequent detrimental effects on cardiac structure and function, and in some cases adverse clinical outcomes such as atrial fibrillation, heart failure and death. There is substantial evidence that patients with reduced left ventricular function(LVEF) are at particular high risk of suffering the detrimental clinical effects of long-term RV pacing. The evidence is, however, incomplete, coming largely from subanalyses of pacemaker and implantable cardiac defibrillator studies. In this group of patients with reduced LVEF and an expected high amount of RV pacing, biventricular pacing(cardiac resynchronization therapy) devices can prevent the negative effects of RV pacing and reduce ventricular dyssynchrony. Therefore, cardiac resynchronization therapy has emerged as an attractive option with promising results and more clinical studies are underway. Furthermore, specific pacemaker algorithms, which minimize RV pacing, can also reduce the negative effects of RV stimulation on cardiac function and may prevent clinical deterioration. | Finn Akerstrm Miguel A Arias Marta Pachón Jesús Jiménez-López Alberto Puchol Justo Juliá-Calvo | 2013 | World Journal of Cardiology2013，5，11： | 3 |
| 3 | Polyethylene glycols: An effective strategy for limiting liver ischemia reperfusion injury显示文摘Liver ischemia-reperfusion injury(IRI) is an inherent feature of liver surgery and liver transplantation in which damage to a hypoxic organ(ischemia) is exacerbated following the return of oxygen delivery(reperfusion). IRI is a major cause of primary nonfunction after transplantation and may lead to graft rejection, regardless of immunological considerations. The immediate response involves the disruption of cellular mitochondrial oxidative phosphorylation and the accumulation of metabolic intermediates during the ischemic period, and oxidative stress during blood flow restoration. Moreover, a complex cascade of inflammatory mediators is generated during reperfusion, contributing to the extension of the damage and finally to organ failure. A variety of pharmacological interventions(antioxidants, anticytokines, etc.) have been proposed to alleviate graft injury but their usefulness is limited by the local and specific action of the drugs and by their potential undesirable toxic effects. Polyethylene glycols(PEGs), which are non-toxic water-soluble compounds approved by the FDA, have been widely used as a vehicle or a base in food, cosmetics and pharmaceuticals, and also as adjuvants for ameliorating drug pharmacokinetics. Some PEGs are also currently used as additives in organ preservation solutions prior to transplantation in order to limit the damage associated with cold ischemia reperfusion. More recently, the administration of PEGs of different molecular weights by intravenous injection has emerged as a new therapeutic tool to protect liver grafts from IRI. In this review, we summarize the current knowledge concerning the use of PEGs as a useful target for limiting liver IRI. | Gianfranco Pasut Arnau Panisello Emma Folch-Puy Alexandre Lopez Carlos Castro-Benítez Maria Calvo Teresa Carbonell Agustín García-Gil RenéAdam Joan Roselló-Catafau | 2016 | World Journal of Gastroenterology2016，22，28： | 3 |
| 4 | Liver fat deposition and mitochondrial dysfunction in morbid obesity:An approach combining metabolomics with liver imaging and histology显示文摘AIM: To explore the usefulness of magnetic resonance imaging(MRI) and spectroscopy(MRS) for assessment of non-alcoholic fat liver disease(NAFLD) as compared with liver histological and metabolomics findings. METHODS: Patients undergoing bariatric surgery following procedures involved in laparoscopic sleeve gastrectomy were recruited as a model of obesityinduced NAFLD in an observational, prospective, singlesite, cross-sectional study with a pre-set duration of 1 year. Relevant data were obtained prospectively and surrogates for inflammation, oxidative stress and lipid and glucose metabolism were obtained through standard laboratory measurements. To provide reliable data from MRI and MRS, novel procedures were designed to limit sampling variability and other sources of error using a 1.5T Signa HDx scanner and protocols acquired from the 3D or 2D Fat SAT FIESTA prescription manager. We used our previously described 1H NMRbased metabolomics assays. Data were obtained immediately before surgery and after a 12-mo period including histology of the liver and measurement of metabolites. Values from 1H NMR spectra obtained after surgery were omitted due to technical limitations.RESULTS: MRI data showed excellent correlation with the concentration of liver triglycerides, other hepatic lipid components and the histological assessment, w h i c h e xc l u d e d t h e p r e s e n c e o f n o n-a l c o h o l i c steatohepatitis(NASH). MRI was sufficient to follow up NAFLD in obese patients undergoing bariatric surgery and data suggest usefulness in other clinical situations. The information provided by MRS replicated that obtained by MRI using the-CH3 peak(0.9 ppm), the-CH2- peak(1.3 ppm, mostly triglyceride) and the-CH=CH- peak(2.2 ppm). No patient depicted NASH. After surgery all patients significantly decreased their body weight and steatosis was virtually absent even in patients with previous severe disease. Improvement was also observed in the serum concentrations of selected variables. The most relevant findings using metabolomics indicate increased levels of triglyceride and monounsaturated fatty acids in severe steatosis but those results were accompanied by a significant depletion of diglycerides, polyunsaturated fatty acids, glucose-6-phosphate and the ATP/AMP ratio. Combined data indicated the coordinated action on mitochondrial fat oxidation and glucose transport activity and may support the consideration of NAFLD as a likely mitochondrial disease. This concept may helpto explain the dissociation between excess lipid storage in adipose tissue and NAFLD and may direct the search for plasma biomarkers and novel therapeutic strategies. A limitation of our study is that data were obtained in a relatively low number of patients.CONCLUSION: MRI is sufficient to stage NAFLD in obese patients and to assess the improvement after bariatric surgery. Other data were superfluous for this purpose. | Nahum Calvo Raúl Beltrán-Debón Esther Rodríguez-Gallego Anna Hernández-Aguilera Maria Guirro Roger Mariné-Casadó Lidón Millá Josep M Alegret Fàtima Sabench Daniel del Castillo María Vinaixa Miguelàngel Rodríguez Xavier Correig Roberto García-álvarez Javier A Menendez Jordi Camps Jorge Joven | 2015 | World Journal of Gastroenterology2015，21，24： | 2 |

| 6 | 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 | 2012 | World Journal of Cardiology2012，4，1： | 2 |
