| 1 | Upper-gastrointestinal bleeding secondary to peptic ulcer disease:Incidence and outcomes显示文摘AIM:To evaluate the incidence,surgery,mortality,and readmission of upper gastrointestinal bleeding(UGIB)secondary to peptic ulcer disease(PUD).METHODS:Administrative databases identified all hospitalizations for UGIB secondary to PUD in Alberta,Canada from 2004 to 2010(n=7079)using the International Classification of Diseases Codes(ICD-10).A subset of the data was validated using endoscopy reports.Positive predictive value and sensitivity with 95%confidence intervals(CI)were calculated.Incidence of UGIB secondary to PUD was calculated.Logistic regression was used to evaluate surgery,in-hospital mortality,and 30-d readmission to hospital with recurrent UGIB secondary to PUD.Co-variants accounted for in our logistic regression model included:age,sex,area of residence(i.e.,urban vs rural),number of Charlson comorbidities,presence of perforated PUD,undergoing upper endoscopy,year of admission,and interventional radiological attempt at controlling bleeding.A subgroup analysis(n=6356)compared outcomes of patients with gastric ulcers to those with duodenal ulcers.Adjusted estimates are presented as odds ratios(OR)with95%CI.RESULTS:The positive predictive value and sensitivity of ICD-10 coding for UGIB secondary to PUD were85.2%(95%CI:80.2%-90.2%)and 77.1%(95%CI:69.1%-85.2%),respectively.The annual incidence between 2004 and 2010 ranged from 35.4 to 41.2 per100000.Overall risk of surgery,in-hospital mortality,and 30-d readmission to hospital for UGIB secondary to PUD were 4.3%,8.5%,and 4.7%,respectively.Interventional radiology to control bleeding was performed in 0.6%of patients and 76%of these patients avoided surgical intervention.Thirty-day readmission significantly increased from 3.1%in 2004 to 5.2%in 2010(OR=1.07;95%CI:1.01-1.14).Rural residents(OR rural vs urban:2.35;95%CI:1.83-3.01)and older individuals(OR≥65 vs<65:1.57;95%CI:1.21-2.04)were at higher odds of being readmitted to hospital.Patients with duodenal ulcers had higher odds of dying(OR=1.27;95%CI:1.05-1.53),requiring surgery(OR=1.73;95%CI:1.34-2.23),and being readmitted to hospital(OR=1.54;95%CI:1.19-1.99)when compared to gastric ulcers.CONCLUSION:UGIB secondary to PUD,particularly duodenal ulcers,was associated with significant morbidity and mortality.Early readmissions increased over time and occurred more commonly in rural areas. | Samuel Quan Alexandra Frolkis Kaylee Milne Natalie Molodecky Hong Yang Elijah Dixon Chad G Ball Robert P Myers Subrata Ghosh Robert Hilsden Sander Veldhuyzen van Zanten Gilaad G Kaplan | 2014 | World Journal of Gastroenterology2014，20，46： | 21 |

| 5 | Effect of hydroalcoholic extract of Hibiscus rosa sinensis Linn.leaves in experimental colitis in rats显示文摘Objective:To elucidate the ameliorative effect of liydrualcuholic extract of leaves of Hibiscus rosa sinensis(HRS) in acetic acid induced experimental colitis in male wistar rats.Methods: The animals were administered with 2 mL acetic acid(4%) via intra rectal.The animals were divided into various treatment groups(n=6).Prednisolone was used as standard drug and HRS was administered at a dose of 50,100 and 200 mg/kg p.o.The control group of animals received 1 mL of vehicle(distilled water).Ulcer area,ulcer index,spleen weight,colon weight to length ratio, macroscopic score,haemalological parameters,colonic superoxide dismutase(SOD),glutathione(GSH),myeloperoxidase(MPO),malondialdchyde(MDA),tumor necrosis factor-α(TNK- α), nitric oxide(NO) and histological changes were recorded after the treatment regimen of 11 days. Results:Intrarectal instillation of acetic acid caused enhanced ulcer area,ulcer index,spleen weight,colon weight to length ratio,colonic MPO,MDA,NO and TNF-α It caused significant decreased level of SOD and GSH.Pretreatment with HRS for 7 days exhibited significant effect in lowering of oxidative stress,colonic NO,TNF- α and elevation of SOD and GSH at a dose of 100 and 200 mg/kg in acetic acid induced colilis.Conclusions:The present investigation demonstrates HRS is of potent therapeutic value in the amelioration of expcrimenlal colilis in laboralory animals by inhibiting the proinflammatory mediator like NO and TNK-α. | Amit D Kandhare Kiran S Raygude Pinaki Ghosh Arvindkumar E Ghule Tejas P Gosavi Sachin L Badole Subhash L Bodhankar | 2012 | Asian Pacific Journal of Tropical Biomedicine2012，2，5： | 2 |
| 6 | Gastric food retention at endoscopy is associated with severity of liver cirrhosis显示文摘BACKGROUND Gastrointestinal symptoms are prevalent in patients with cirrhosis.Cirrhotic patients have a known predilection to delayed gastric emptying compared to those without cirrhosis.However,the contributing factors have not been fully elucidated.Retained gastric food on esophagogastroduodenoscopy(EGD)has been used as a surrogate marker for delayed gastric emptying with reasonably high specificity.Therefore,we hypothesize that the frequency of retained gastric food contents at EGD will be higher in a cirrhotic population compared to a control population without liver disease.Additionally,we hypothesize that increased frequency of gastric food contents will be associated with increased severity of cirrhosis.AIM To determine the relative frequency of delayed gastric emptying among cirrhotics as compared to non-cirrhotics and to identify associated factors.METHODSWe performed a retrospective case-control study of cirrhotic subjects whounderwent EGD at an academic medical center between 2000 and 2015. Threehundred sixty-four patients with confirmed cirrhosis, who underwent a total of1044 EGDs for the indication of esophageal variceal screening or surveillance,were identified. During the same period, 519 control patients without liverdisease, who underwent a total of 881 EGDs for the indication of anemia, wereidentified. The presence of retained food on EGD was used as a surrogate fordelayed gastric emptying. The relative frequency of delayed gastric emptyingamong cirrhotics was compared to non-cirrhotics. Characteristics of patients withand without retained food on EGD were compared using univariable andmultivariable logistic regression analysis to identify associated factors.RESULTSOverall, 40 (4.5%) patients had evidence of retained food on EGD. Cirrhotics weremore likely to have retained food on EGD than non-cirrhotics (9.1% vs 1.4%, P <0.001). Characteristics associated with retained food on univariable analysisincluded age less than 60 years (12.6% vs 5.2%, P = 0.015), opioid use (P = 0.004),Child-Pugh class C (24.1% Child-Pugh class C vs 6.4% Child-Pugh class A, P =0.007), and lower platelet count (P = 0.027). On multivariate logistic regressionanalysis, in addition to the presence of cirrhosis (adjusted OR = 5.83;95%CI: 2.32-14.7, P < 0.001), diabetes mellitus (types 1 and 2 combined) (OR = 2.34;95%CI:1.08-5.06, P = 0.031), opioid use (OR = 3.08;95%CI: 1.29-7.34, P = 0.011), andChild-Pugh class C (OR = 4.29;95%CI: 1.43-12.9, P = 0.01) were also associatedwith a higher likelihood of food retention on EGD.CONCLUSIONCirrhotics have a higher frequency of retained food at EGD than non-cirrhotics.Decompensated cirrhosis, defined by Child-Pugh class C, is associated with ahigher likelihood of delayed gastric emptying. | David B Snell Shirley Cohen-Mekelburg Russell Weg Gaurav Ghosh Adam P Buckholz Amit Mehta Xiaoyue Ma Paul J Christos Arun B Jesudian | 2019 | World Journal of Hepatology2019，11，11： | 2 |
