| 1 | miR-200 family expression is downregulated upon neoplastic progression of Barrett's esophagus显示文摘AIM: To investigate miR-200 family expression in Barrett's epithelium, gastric and duodenal epithelia, and esophageal adenocarcinoma. METHODS: Real-time reverse transcriptase-polymerase chain reaction was used to measure miR-200, ZEB1 and ZEB2 expression. Ingenuity Pathway Analysis of miR-200 targets was used to predict biological outcomes. RESULTS: Barrett's epithelium expressed lower levels of miR-141 and miR-200c than did gastric and duodenal epithelia (P < 0.001). In silico analysis indicated roles for the miR-200 family in molecular pathways that distinguish Barrett's epithelium from gastric and duodenalepithelia, and which control apoptosis and proliferation. All miR-200 members were downregulated in adenocarcinoma (P < 0.02), and miR-200c expression was also downregulated in non-invasive epithelium adjacent to adenocarcinoma (P < 0.02). The expression of all miR-200 members was lower in Barrett's epithelium derived high-grade dysplastic cell lines than in a cell line derived from benign Barrett's epithelium. We observed signif icant inverse correlations between miR-200 family expression and ZEB1 and ZEB2 expression in Barrett's epithelium and esophageal adenocarcinoma (P < 0.05). CONCLUSION: miR-200 expression might contribute to the anti-apoptotic and proliferative phenotype of Barrett's epithelium and regulate key neoplastic processes in this epithelium. | Cameron M Smith David I Watson Mary P Leong George C Mayne Michael Z Michael Bas PL Wijnhoven Damian J Hussey | 2011 | World Journal of Gastroenterology2011,17,8: | 13 |
| 2 | Lesion-symptom mapping with NIHSS sub-scores in ischemic stroke patients显示文摘Background Lesion-symptom mapping(LSM)is a statistical technique to investigate the population-specific relationship between structural integrity and post-stroke clinical outcome.In clinical practice,patients are commonly evaluated using the National Institutes of Health Stroke Scale(NIHSS),an 11-domain clinical score to quantitate neurological deficits due to stroke.So far,LSM studies have mostly used the total NIHSS score for analysis,which might not uncover subtle structure–function relationships associated with the specific sub-domains of the NIHSS evaluation.Thus,the aim of this work was to investigate the feasibility to perform LSM analyses with sub-score information to reveal category-specific structure–function relationships that a total score may not reveal.Methods Employing a multivariate technique,LSM analyses were conducted using a sample of 180 patients with NIHSS assessment at 48-hour post-stroke from the ESCAPE trial.The NIHSS domains were grouped into six categories using two schemes.LSM was conducted for each category of the two groupings and the total NIHSS score.Results Sub-score LSMs not only identify most of the brain regions that are identified as critical by the total NIHSS score but also reveal additional brain regions critical to each function category of the NIHSS assessment without requiring extensive,specialised assessments.Conclusion These findings show that widely available sub-scores of clinical outcome assessments can be used to investigate more specific structure–function relationships,which may improve predictive modelling of stroke outcomes in the context of modern clinical stroke assessments and neuroimaging. | Deepthi Rajashekar Matthias Wilms M Ethan MacDonald Serena Schimert Michael D Hill Andrew Demchuk Mayank Goyal Sean P Dukelow Nils Daniel Forkert | 2022 | Stroke & Vascular Neurology2022,7,2: | 7 |

| 4 | Response to endoscopic therapy for biliary anastomotic strictures in deceased versus living donor liver transplantation显示文摘BACKGROUND:Endoscopic therapy has been successful in the management of biliary complications after both deceased donor liver transplantation(DDLT) and living donor liver transplantation(LDLT).LDLT is thought to be associated with higher rates of biliary complications,but there are few studies comparing the success of endoscopic management of anastomotic strictures between the two groups.This study aims to compare our experience in the endoscopic management of anastomotic strictures in DDLT versus LDLT.METHODS:This is a retrospective database review of all liver transplant patients undergoing endoscopic retrograde cholangiopancreatography(ERCP) after liver transplantation.The frequency of anastomotic stricture and the time to develop and to resolve anastomotic stricture were compared between DDLT and LDLT.The response of anastomotic stricture to endoscopic therapy was also analyzed.RESULTS:A total of 362 patients underwent liver transplantation between 2003 and 2011,with 125 requiring ERCP to manage biliary complications.Thirty-three(9.9%) cases of DDLT and 8(27.6%) of LDLT(P=0.01) were found to have anastomotic stricture.When comparing DDLT and LDLT,there was no difference in the mean time to the development of anastomotic strictures(98±17 vs 172±65 days,P=0.11),likelihood of response to ERCP [22(66.7%) vs 6(75.0%),P=0.69],mean time to the resolution of anastomotic strictures(268±77 vs 125±37 days,P=0.34),and the number of ERCPs required to achieve resolution(3.9±0.4 vs 4.7±0.9,P=0.38).CONCLUSIONS:Endoscopic therapy is effective in the majority of biliary complications relating to liver transplantation.Anastomotic strictures occur more frequently in LDLT compared with DDLT,with equivalent endoscopic treatment response and outcomes for both groups. | Calvin HY Chan Fergal Donnellan Michael F Byrne Alan Coss Mazhar Haque Holly Wiesenger Charles H Scudamore Urs P Steinbrecher Alan A Weiss Eric M Yoshida | 2013 | Hepatobiliary & Pancreatic Diseases International2013,12,5: | 7 |
| 5 | Computed tomography and patient risk:Facts,perceptions and uncertainties显示文摘Since its introduction in the 1970s, computed tomography(CT) has revolutionized diagnostic decision-making. One of the major concerns associated with the widespread use of CT is the associated increased radiation exposure incurred by patients. The link between ionizing radiation and the subsequent development of neoplasia has been largely based on extrapolating data from studies of survivors of the atomic bombs dropped in Japan in 1945 and on assessments of the increased relative risk of neoplasia in those occupationally exposed to radiation within the nuclear industry. However, the association between exposure to low-dose radiation from diagnostic imaging examinations and oncogenesis remains unclear. With improved technology, significant advances have already been achieved with regards to radiation dose reduction. There are several dose optimization strategies available that may be readily employed including omitting unnecessary images at the ends of acquired series, minimizing the number of phases acquired, and the use of automated exposure control as opposed to fixed tube current techniques. In addition, new image reconstruction techniques that reduce radiation dose have been developed in recent years with promising results. These techniques use iterative reconstruction algorithms to attain diagnostic quality images with reduced image noise at lower radiation doses. | Stephen P Power Fiachra Moloney Maria Twomey Karl James Owen J O'Connor Michael M Maher | 2016 | World Journal of Radiology2016,8,12: | 7 |
| 6 | Long-term irritable bowel syndrome symptom control with reintroduction of selected FODMAPs显示文摘AIM To investigate the long-term effect of dietary education on a low fermentable oligosaccharide, disaccharide and polyol(FODMAP) diet on irritable bowel syndrome(IBS) symptoms and quality of life(Qo L).METHODS Participants with IBS(Rome III) were randomized to two groups. Group I commenced a low FODMAP diet at baseline. At three months, group II, so far a comparator group, crossed over to a low FODMAP diet while group I started re-challenging foods. All patients completed the IBS SSS(IBS symptom severity scoring system, 0-500 points increasing with severity), IBS Qo L questionnaire(0-100 increasing with Qo L), a FODMAP specific food frequency questionnaire and provided a stool sample at baseline, three and six months for microbiome analysis.RESULTS Fifty participants were enrolled into group I(n = 23) or group II(n = 27). Participants in both groups were similar in baseline values but with more men in group I. There was a significantly lower IBS SSS(275.6 ± 63.6 to 128.8 ± 82.5 vs 246.8 ± 71.1 to 203.6 ± 70.1)(P < 0.0002) and increased Qo L(68.5 ± 18.0 to 83 ± 13.4 vs 72.9 ± 12.8 to 73.3 ± 14.4)(P < 0.0001) in group I vs group II at 3 mo. The reduced IBS SSS was sustained at 6 mo in group I(160 ± 102) and replicated in group II(124 ± 76). Fiber intake decreased on the low FODMAP diet(33 ± 17 g/d to 21 ± 8 g/d)(P < 0.01) and after re-introducing FODMAP containing foods increased again to 27 ± 9 g/d. There was no change seen in the intestinal microbiome when participants adopted a low FODMAP diet.CONCLUSION This study demonstrated that a reduction in FODMAPs improves symptoms in IBS and this improvement can be maintained while reintroducing FODMAPs. | Ruth M Harvie Alexandra W Chisholm Jordan E Bisanz Jeremy P Burton Peter Herbison Kim Schultz Michael Schultz | 2017 | World Journal of Gastroenterology2017,23,25: | 5 |
| 7 | Role of interleukin-1 and its antagonism of hepatic stellate cell proliferation and liver fibrosis in the Abcb4^(-/-) mouse model显示文摘AIM: To study the interleukin-1(IL-1) pathway as a therapeutic target for liver fibrosis in vitro and in vivo using the ATP-binding cassette transporter b4^(-/-)(Abcb4^(-/-)) mouse model.METHODS: Female and male Abcb4^(-/-) mice from 6 to 13 mo of age were analysed for the degree of cholestasis(liver serum tests), extent of liver fibrosis(hydroxyproline content and Sirius red staining) and tissue-specific activation of signalling pathways such as the IL-1 pathway [quantitative polymerase chain reaction(q PCR)]. For in vivo experiments, murine hepatic stellate cells(HSCs) were isolated via pronasecollagenase perfusion followed by density gradient centrifugation using female mice. Murine HSCs were stimulated with up to 1 ng/m L IL-1β with or without 2.5 μg/m L Anakinra, an IL-1 receptor antagonist, respectively. The proliferation of murine HSCs was assessed via the Brd U assay. The toxicity of Anakinra was evaluated via the fluorescein diacetate hydrolysis(FDH) assay. In vivo 8-wk-old Abcb4^(-/-) mice with an already fully established hepatic phenotype were treated with Anakinra(1 mg/kg body-weight daily intraperitoneally) or vehicle and liver injury and liver fibrosis were evaluated via serum tests, q PCR, hydroxyproline content and Sirius red staining. RESULTS: Liver fibrosis was less pronounced in males than in female Abcb4^(-/-) animals as defined by a lower hydroxyproline content(274 ± 64 μg/g vs 436 ± 80 μg/g liver, respectively; n = 13-15; P < 0.001; MannWhitney U-test) and lower m RNA expression of the profibrogenic tissue inhibitor of metalloproteinase-1(TIMP)(1 ± 0.41 vs 0.66 ± 0.33 fold, respectively; n = 13-15; P < 0.05; Mann-Whitney U-test). Reduced liver fibrosis was associated with significantly lower levels of F4/80 m RNA expression(1 ± 0.28 vs 0.71 ± 0.41 fold, respectively; n = 12-15; P < 0.05; Mann-Whitney U-test) and significantly lower IL-1β m RNA expression levels(1 ± 0.38 vs 0.44 ± 0.26 fold, respectively; n = 13-15; P < 0.001; Mann-Whitney U-test). No gender differences in the serum liver parameters [bilirubin; alanine aminotransferase(ALT); aspartate aminotransferase and alkaline phosphatase(AP)] were found. In vitro, the administration of IL-1β resulted in a significant increase in HSC proliferation [0.94 ± 0.72 arbitrary units(A.U.) in untreated controls, 1.12 ± 0.80 A.U. at an IL-1β concentration of 0.1 ng/m L and 1.18 ± 0.73 A.U. at an IL-1β concentration of 1 ng/m L in samples from n = 6 donor animals; P < 0.001; analyses of variance(ANOVA)]. Proliferation was reduced significantly by the addition of 2.5 μg/m L Anakinra(0.81 ± 0.60 A.U. in untreated controls, 0.92 ± 0.68 A.U. at an IL-1β concentration of 0.1 ng/m L, and 0.91 ± 0.69 A.U. at an IL-1β concentration of 1 ng/m L; in samples from n = 6 donor animals; P < 0.001; ANOVA) suggesting an anti-proliferative effect of this clinically approved IL-1 receptor antagonist. The FDH assay showed this dose to be non-toxic in HSCs. In vivo, Anakinra had no effect on the hepatic hydroxyprolinecontent, liver serum tests(ALT and AP) and profibrotic(collagen 1α1, collagen 1α2, transforming growth factor-β, and TIMP-1) and anti-fibrotic [matrix metalloproteinase 2(MMP2), MMP9 and MMP13 ] gene expression after 4 wk of treatment. Furthermore, the hepatic IL-1β and F4/80 m RNA expression levels were unaffected by Anakinra treatment.CONCLUSION: IL-1β expression is associated with the degree of liver fibrosis in Abcb4^(-/-) mice and promotes HSC proliferation. IL-1 antagonism shows antifibrotic effects in vitro but not in Abcb4^(-/-) mice. | Florian P Reiter Ralf Wimmer Lena Wottke Renate Artmann Jutta M Nagel Manuel O Carranza Doris Mayr Christian Rust Peter Fickert Michael Trauner Alexander L Gerbes Simon Hohenester Gerald U Denk | 2016 | World Journal of Hepatology2016,8,8: | 3 |

| 9 | Pediatric Nd:YAG laser capsulotomy in the operating room: review of 87 cases显示文摘AIM: To report a large series of children having Nd:YAG laser capsulotomy in the operating room using the lateral decubitus position. METHODS: Medical records of children who underwent Nd:YAG laser capsulotomy in the operating room at Ann & Robert H. Lurie Children's Hospital of Chicago between September 2008 and April 2017 were reviewed. Induction of general anesthesia and intubation was performed in the supine position after which the patient was placed in lateral decubitus position. The Nd:YAG laser capsulotomy was performed using a standard protocol. At the completion of the procedure, the patient was turned back into the supine position and extubated. RESULTS: This study included 87 eyes of 60 patients. Patient's age ranged from 1 to 18 y(mean 6.4±4.1 y). In most cases(84/87, 97%), the procedure was performed under general anesthesia. In all cases, good focus on the membrane was achieved, and the procedure was performed successfully. There were no intraoperative ocular or anesthesia-related complications. CONCLUSION: When performing Nd:YAG laser capsulotomy in the operating room, the lateral decubitus position allowsan easy and safe approach without the risk of potentially devastating complications that have been associated with the previously described sitting and prone positions. | Michael Kinori Narasimhan Jagannathan Anne M Langguth Marjorie A Sasso Marilyn B Mets Bahram Rahmani Hawke Yoon Rebecca Mets-Halgrimson Sudhi P Kurup Janice L Zeid | 2019 | International Journal of Ophthalmology(English edition)2019,12,5: | 2 |
| 10 | C-reactive protein and radiographic findings of lower respiratory tract infection in infants显示文摘AIM To evaluate the association between C-reactive protein(CRP) and radiological evidence of lower respiratory tract infection(LRTI) in infants.METHODS All patients aged less than 4 years who presented with suspected lower respiratory tract infection,who received a peri-presentation chest radiograph and CRP blood measurement over an 18-mo period were included in the study.Age,gender,source of referral,CRP,white cell count,neutrophil count along with the patients' symptoms and radiologist's report were recorded.RESULTS Three hundred and eleven patients met the inclusioncriteria.Abnormal chest radiographs were more common in patients with elevated CRP levels(P < 0.01).Radiologic signs of LRTI were identified in 73.7% of chest radiographs when a patient had a CRP level between 50-99 mg/L.CRP levels were a better predictor of positive chest radiograph findings for those aged greater than I year compared to those 1 year or less.CONCLUSION CRP may be used in patients with suspected LRTI diagnosis to select those who are likely to have positive findings on chest radiograph,thus reducing unnecessary chest radiographs. | Maria Twomey Hannah Fleming Fiachra Moloney Kevin P Murphy Lee Crush Siobhan B O’Neill Oisin Flanagan Karl James Conor Bogue Owen J O’Connor Michael M Maher | 2017 | World Journal of Radiology2017,9,4: | 2 |
| 11 | Outcomes after arthroscopic repair of rotator cuff tears in the setting of mild to moderate glenohumeral osteoarthritis显示文摘BACKGROUND Rotator cuff pathology is a very common source of shoulder pain.Similarly,osteoarthritis of the glenohumeral joint can cause shoulder pain and produce similar symptoms.Surgical management can be indicated for both pathologies,however,outcomes data is limited when examining rotator cuff repair(RCR) in the setting of glenohumeral arthritis(GHOA).Thus,this study sought to determine outcomes for patients who undergo RCR in the setting of GHOA.AIM To evaluate if a relationship exists between outcomes of RCR in the setting of GHOA.METHODS This was a retrospective analysis of patients who underwent arthroscopic rotator cuff repair with concurrent glenohumeral osteoarthritis between 2010-2017.Patients were stratified based on rotator cuff tear size and glenohumeral osteoarthritis severity.Cohorts were paired 1:1 with patients without glenohumeral osteoarthritis.Patients included had a minimum two year follow-up.Rate of conversion to total shoulder arthroplasty,complication rates following initial surgery,and patient-reported outcome measures were collected.RESULTS A total of 142 patients were included.The number of patients that required total shoulder arthroplasty within two years after index surgery was low.2/71(2.8%) patients with GHOA,and 1/71(1.4%) without GHOA.Following rotator cuff repair,both groups showed favorable patientreported outcomes.CONCLUSION Patients with glenohumeral osteoarthritis who underwent arthroscopic rotator cuff repair showed comparable outcomes to patients without glenohumeral osteoarthritis. | Ian S Hong Allison J Rao Tyler L CarlLee Joshua D Meade Daniel J Hurwit Gregory Scarola David P Trofa Shadley C Schiffern Nady Hamid Patrick M Connor James E Fleischli Bryan Michael Saltzman | 2022 | World Journal of Orthopedics2022,13,7: | 2 |
