| 1 | Predictors of suboptimal bowel preparation in asymptomatic patients undergoing average-risk screening colonoscopy显示文摘AIM To identify risk factors for a suboptimal preparation among a population undergoing screening or surveillance colonoscopy.METHODS Retrospective review of the University of Michigan and Veteran's Administration(VA) Hospital records from 2009 to identify patients age 50 and older who underwent screening or surveillance procedure and had resection of polyps less than 1 cm in size and no more than 2 polyps. Patients with inflammatory bowel disease or a family history of colorectal cancer were excluded. Suboptimal procedures were defined as procedure preparations categorized as fair, poor or inadequate by the endoscopist. Multivariable logistic regression was used to identify predictors of suboptimal preparation.RESULTS Of 4427 colonoscopies reviewed, 2401 met our inclusion criteria and were analyzed. Of our population, 16% had a suboptimal preparation. African Americans were 70% more likely to have a suboptimal preparation(95%CI: 1.2-2.4). Univariable analysis revealed that narcotic and tricyclic antidepressants(TCA) use, diabetes, prep type, site(VA vs non-VA), and presence of a gastroenterology(GI) fellow were associated with suboptimal prep quality. In a multivariable model controlling for gender, age, ethnicity, procedure site and presence of a GI fellow, diabetes [odds ratio(OR) = 2.3; 95%CI: 1.6-3.2], TCA use(OR = 2.5; 95%CI: 1.3-4.9), narcotic use(OR = 1.7; 95%CI: 1.2-2.5) and Miralax-Gatorade prep vs 4L polyethylene glycol 3350(OR = 0.6; 95%CI: 0.4-0.9) were associated with a suboptimal prep quality. CONCLUSION Diabetes, narcotics use and TCA use were identified as predictors of poor preparation in screening colonoscopies while Miralax-Gatorade preps were associated with better bowel preparation. | Shail M Govani Eric E Elliott Stacy B Menees Stephanie L Judd Sameer D Saini Constantinos P Anastassiades Annette L Urganus Suzanna J Boyce Philip S Schoenfeld | 2016 | World Journal of Gastrointestinal Endoscopy2016，8，17： | 7 |
| 2 | Nonalcoholic steatohepatitis severity is defined by a failure in compensatory antioxidant capacity in the setting of mitochondrial dysfunction显示文摘AIM To comprehensively evaluate mitochondrial(dys) function in preclinical models of nonalcoholic steatohepatitis(NASH).METHODS We utilized two readily available mouse models of nonalcoholic fatty liver disease(NAFLD) with or without progressive fibrosis: Lep^(ob)/Lep^(ob)(ob/ob) and FATZO mice on high trans-fat, high fructose and high cholesterol(AMLN) diet. Presence of NASH was assessed using immunohistochemical and pathological techniques, and gene expression profiling. Morphological features of mitochondria were assessed via transmission electron microscopy and immunofluorescence, and function was assessed by measuring oxidative capacity in primary hepatocytes, and respiratory control and proton leak in isolated mitochondria. Oxidative stress was measured by assessing activity and/or expression levels of Nrf1, Sod1, Sod2, catalase and 8-OHdG. RESULTS When challenged with AMLN diet for 12 wk, ob/ob and FATZO mice developed steatohepatitis in the presence of obesity and hyperinsulinemia. NASH development was associated with hepatic mitochondrial abnormalities, similar to those previously observed in humans, including mitochondrial accumulation and increased proton leak. AMLN diet also resulted in increased numbers of fragmented mitochondria in both strains of mice. Despite similar mitochondrial phenotypes, we found that ob/ob mice developed more advanced hepatic fibrosis. Activity of superoxide dismutase(SOD) was increased in ob/ob AMLN mice, whereas FATZO mice displayed increased catalase activity, irrespective of diet. Furthermore, 8-OHd G, a marker of oxidative DNA damage, was significantly increased in ob/ob AMLN mice compared to FATZO AMLN mice. Therefore, antioxidant capacity reflected as the ratio of catalase:SOD activity was similar between FATZO and C57 BL6 J control mice, but significantly perturbed in ob/ob mice. CONCLUSION Oxidative stress, and/or the capacity to compensate for increased oxidative stress, in the setting of mitochondrial dysfunction, is a key factor for development of hepatic injury and fibrosis in these mouse models. | Michelle L Boland Stephanie Oldham Brandon B Boland Sarah Will Jean-Martin Lapointe Silvia Guionaud Christopher J Rhodes James L Trevaskis | 2018 | World Journal of Gastroenterology2018，24，16： | 7 |

| 4 | Secondary angiodysplasia-associated gastrointestinal bleeding in end-stage renal disease: Results from the nationwide inpatient sample显示文摘BACKGROUND Chronic kidney disease is associated with angiodysplasia of gastrointestinal tract leading to increased risk of gastrointestinal bleeding.AIM To determine the nationwide prevalence,trends,predictors and resource utilization of angiodysplasia-associated gastrointestinal bleeding in end-stage renal disease hospitalizations.METHODS The Nationwide Inpatient Sample database from 2009 to 2014,was utilized to conduct a retrospective study on patients with angiodysplasia associatedgastrointestinal bleeding and end-stage renal disease.Hospitalizations with endstage renal disease were included in the Nationwide Inpatient Sample database and a subset of hospitalizations with end-stage renal disease and angiodysplasiaassociated gastrointestinal bleeding were identified with International Classification of Diseases,9th revision,Clinical Modification codes for both endstage renal disease(585.6)and angiodysplasia(569.85,537.83).RESULTS The prevalence of angiodysplasia-associated gastrointestinal bleeding was 0.45%(n=24709)among all end-stage renal disease patients(n=5505252)that were hospitalized.Multivariate analysis indicated that the following were significant factors associated with higher odds of angiodysplasia associated-gastrointestinal bleeding in end-stage renal disease patients:an increasing trend from 2009-2014(P<0.01),increasing age(P<0.0001);African American race(P=0.0206);increasing Charlson-Deyo Comorbidity Index(P<0.01);hypertension(P<0.0001);and tobacco use(P<0.0001).Diabetes mellitus(P<0.0001)was associated with lower odds of angiodysplasia associated-gastrointestinal bleeding in end-stage renal disease patients.In comparison with urban teaching hospitals,rural and urban nonteaching hospitals were associated with decreased odds of angiodysplasia associated-gastrointestinal hemorrhage.CONCLUSION Angiodysplasia-associated gastrointestinal bleeding in end-stage renal disease patients showed an increasing trend from 2009-2014.Advanced age,African American race,overall high comorbidities,hypertension and smoking were significant factors for angiodysplasia-associated gastrointestinal bleeding in bleeding in these patients. | Tooba Tariq Patrick Karabon Furqan B Irfan Sachin Goyal Matthew Masaru Mayeda Austin Parsons Stephanie Judd Murray Ehrinpreis | 2019 | World Journal of Gastrointestinal Endoscopy2019，11，10： | 3 |
