| 1 | Retrograde-viewing device improves adenoma detection rate in colonoscopies for surveillance and diagnostic workup显示文摘AIM:To determine which patients might benefit most from retrograde viewing during colonoscopy through subset analysis of randomized,controlled trial data.METHODS:The Third Eye Retroscope Randomized Clinical Evaluation(TERRACE) was a randomized,controlled,multicenter trial designed to evaluate the efficacy of a retrograde-viewing auxiliary imaging device that is used during colonoscopy to provide a second video image which allows viewing of areas on the proximal aspect of haustral folds and flexures that are difficult to see with the colonoscope's forward view.We performed a post-hoc analysis of the TERRACE data to determine whether certain subsets of the patient population would gain more benefit than others from use of the device.Subjects were patients scheduled for colonoscopy for screening,surveillance or diagnostic workup,and each underwent same-day tandem examinations with standard colonoscopy(SC) and Third Eye colonoscopy(TEC),randomized to SC followed by TEC or vice versa.RESULTS:Indication for colonoscopy was screening in 176/345 subjects(51.0%),surveillance after previous polypectomy in 87(25.2%) and diagnostic workup in 82(23.8%).In 4 subjects no indication was specified.Previously reported overall results had shown a net additional adenoma detection rate(ADR) with TEC of 23.2% compared to SC.Relative risk(RR) of missing adenomas with SC vs TEC as the initial procedure was 1.92(P = 0.029).Post-hoc subset analysis shows additional ADRs for TEC compared to SC were 4.4% for screening,35.7% for surveillance,55.4% for diagnostic and 40.7% for surveillance and diagnostic combined.The RR of missing adenomas with SC vs TEC was 1.11(P = 0.815) for screening,3.15(P = 0.014) for surveillance,8.64(P = 0.039) for diagnostic and 3.34(P = 0.003) for surveillance and diagnostic combined.Although a multivariate Poisson regression suggested gender as a possibly significant factor,subset analysis showed that the difference between genders was not statistically significant.Age,bowel prep quality and withdrawal time did not significantly affect the RR of missing adenomas with SC vs TEC.Mean sizes of adenomas detected with TEC and SC were similar at 0.59 cm and 0.56 cm,respectively(P = NS).CONCLUSION:TEC allows detection of significantly more adenomas compared to SC in patients undergoing surveillance or diagnostic workup,but not in screening patients(ClinicalTrials.gov Identifier:NCT01044732). | Peter D Siersema Amit Rastogi Anke M Leufkens Paul A Akerman Kassem Azzouzi Richard I Rothstein Frank P Vleggaar Alessandro Repici Giacomo Rando Patrick I Okolo Olivier Dewit Ana Ignjatovic Elizabeth Odstrcil James East Pierre H Deprez Brian P Saunders Anthony N Kalloo Bradley Creel Vikas Singh Anne Marie Lennon Daniel C DeMarco | 2012 | World Journal of Gastroenterology2012，18，26： | 6 |
| 2 | Computerized tomography based “patient specific blocks” improve postoperative mechanical alignment in primary total knee arthroplasty显示文摘AIM: To compare the postoperative mechanical alignment achieved after total knee arthroplasty(TKA) using computer tomography(CT) based patient specific blocks(PSB) to conventional instruments(CI).METHODS: Total 80 knees were included in the study, with 40 knees in both the groups operated using PSB and CI. All the knees were performed by a single surgeon using the same cruciate sacrificing implants. In our study we used CT based PSB to compare with CI. Postoperative mechanical femoro-tibial angle(MFT angle) was measured on long leg x-rays using picture archiving and communication system(PACS). We compared mechanical alignment achieved using PSB and CI in TKA using statistical analysis.RESULTS: The PSB group(group 1) included 17 females and seven males while in CI group(group 2) there were 15 females and eight males. The mean age of patients in group 1 was 60.5 years and in group 2 it was 60.2 years. The mean postoperative MFT angle measured on long-leg radiographs in group 1 was 178.23°(SD = 2.67°, range: 171.9° to 182.5°) while in group 2, the mean MFT angle was 175.73°(SD = 3.62°, range: 166.0° to 179.8°). There was significant improvement in postoperative mechanical alignment(P value = 0.001), in PSB group compared to CI. Number of outliers were also found to be less in group operated with PSB(7 Knee) compared to those operated with CI(17 Knee).CONCLUSION: PSB improve mechanical alignment after total knee arthroplasty, compared to CI. This may lead to lower rates of revision in the PSB based TKA as compared to the conventional instrumentation. | Raju Vaishya Vipul Vijay Vikas P Birla Amit K Agarwal | 2016 | World Journal of Orthopedics2016，7，7： | 2 |
| 3 | 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 |
| 4 | 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 |
