| 1 | Characterisation and risk assessment of venous thromboembolism in gastrointestinal cancers显示文摘AIM To characterise venous thromboembolism(VTE) in gastrointestinal cancer and assess the clinical utility of risk stratification scoring. METHODS We performed a retrospective analysis using electronic patient records of 910 gastro-oesophageal(GO) cancer and 1299 colorectal cancer(CRC) patients referred to a tertiary cancer centre to identify the incidence of VTE, its relationship to chemotherapy and impact on survival.VTE risk scores were calculated using the Khorana index. Patients were classified as low risk(0 points), intermediate risk(1 to 2 points) or high risk(3 points). Data was analysed to determine the sensitivity of the Khorana score to predict VTE. RESULTS The incidence of VTE was 8.9% for CRC patients and 9.7% for GO cancer patients. Pulmonary emboli(PE) were more common in advanced than in localised CRC(50% vs 21% of events respectively) and lower limb deep vein thrombosis(DVT) were more common in localised than in advanced CRC(62% vs 39% of events respectively). The median time to VTE from cancer diagnosis was 8.3 mo for CRC patients compared to 6.7 mo in GO cancer. In localised CRC median time to VTE was 7.1 mo compared with 10.1 mo in advanced CRC. In contrast in GO cancer, the median time to VTE was 12.5 mo in localised disease and 6.8 mo in advanced disease. No survival difference was seen between patients with and without VTE in this cohort. The majority of patients with CRC in whom VTE was diagnosed had low or intermediate Khorana risk score(94% for localised and 97% in advanced CRC). In GO cancer, all patients scored either intermediate or high risk due to the primary site demonstrating a limitation of the risk assessment score in discriminating high and low risk patients with GO cancers. Additional risk factors were identified in this cohort including surgery, chemotherapy or hospital admission. Overall, 81% of patients with CRC and 77% of patients with GO cancer had one or more of these factors within 4 wk prior to diagnosis VTE. These should be factored into clinical risk assessment scores. CONCLUSION The Khorana score has low sensitivity for thrombotic events in CRC and cannot discriminate low risk patients in high risk cancer sites such as GO cancer. | Robert L Metcalf Eamon Al-Hadithi Nicholas Hopley Thomas Henry Clare Hodgson Antony McGurk Wasat Mansoor Jurjees Hasan | 2017 | World Journal of Gastrointestinal Oncology2017，9，9： | 10 |
| 2 | Preservation solutions used during abdominal transplantation:Current status and outcomes显示文摘Organ preservation remains an important contributing factor to graft and patient outcomes. During donor organ procurement and transportation, cellular injury is mitigated through the use of preservation solutions in conjunction with hypothermia. Various preservation solutions and protocols exist with widespread variability among transplant centers. In this review of abdominal organ preservation solutions, evolution of transplantation and graft preservation are discussed followed by classification of preservation solutions according to the composition of electrolytes, impermeants, buffers, antioxidants, and energy precursors. Lastly, pertinent clinical studies in the setting of hepatic, renal, pancreas, and intestinal transplantation are reviewed for patient and graft survival as well as financial considerations. In liver transplants there may be some benefit with the use of histidine-tryptophan-ketoglutarate(HTK) over University of Wisconsin solution in terms of biliary complications and potential cost savings. Renal grafts may experience increased initial graft dysfunction with the use of Euro-Collins thereby dissuading its use in support of HTK which can lead to substantial cost savings. University of Wisconsin solution and Celsior are favored in pancreas transplants given the concern for pancreatitis and graft thrombosis associated with HTK. No difference was observed with preservation solutions with respect to graft and patient survival in liver, renal, and pancreas transplants. Studies involving intestinal transplants are sparse but University of Wisconsin solution infused intraluminally in combination with an intra-vascular washout is a reasonable option until further evidence can be generated. Available literature can be used to ameliorate extensive variation across centers while potentially minimizing graft dysfunction and improving associated costs. | Nicholas Latchana Joshua R Peck Bryan A Whitson Mitchell L Henry Elmahdi A Elkhammas Sylvester M Black | 2015 | World Journal of Transplantation2015，5，4： | 5 |

| 4 | Revisiting the Concentration Observations and Source Apportionment of Atmospheric Ammonia显示文摘While China’s Air Pollution Prevention and Control Action Plan on particulate matter since 2013 has reduced sulfate significantly,aerosol ammonium nitrate remains high in East China.As the high nitrate abundances are strongly linked with ammonia,reducing ammonia emissions is becoming increasingly important to improve the air quality of China.Although satellite data provide evidence of substantial increases in atmospheric ammonia concentrations over major agricultural regions,long-term surface observation of ammonia concentrations are sparse.In addition,there is still no consensus on whether agricultural or non-agricultural emissions dominate the urban ammonia budget.Identifying the ammonia source by nitrogen isotope helps in designing a mitigation strategy for policymakers,but existing methods have not been well validated.Revisiting the concentration measurements and identifying source apportionment of atmospheric ammonia is thus an essential step towards reducing ammonia emissions. | Yuepeng PAN Mengna GU Yuexin HE Dianming WU Chunyan LIU Linlin SONG Shili TIAN Xuemei LÜ Yang SUN Tao SONG Wendell WWALTERS Xuejun LIU Nicholas AMARTIN Qianqian ZHANG Yunting FANG Valerio FERRACCI Yuesi WANG | 2020 | Advances in Atmospheric Sciences2020，37，9： | 4 |
| 5 | Predictors of double balloon endoscopy outcomes in the evaluation of gastrointestinal bleeding显示文摘AIM:To identify patients' characteristics associated with double balloon endoscopy(DBE)outcomes in investigation of obscure gastrointestinal bleeding(OGIB).METHODS:Retrospective study performed at an academic tertiary referral center.Evaluated endpoints were clinical factors associated with no diagnostic yield or non-therapeutic intervention of DBE performed for OGIB evaluation.RESULTS:We included fifty-five DBE between August 2010 and April 2012.The mean age of the sample was 67 with 32 males(58.2%).Twenty-four DBE had no diagnostic yield and 30 DBE did not require therapy.Non-diagnostic yield was associated with performing two or more DBE studies in one day [odds ratio(OR):13.72,P=0.008],absence of blood transfusions within a year of the DBE(OR:7.16,P=0.03)and absence of ulcers or arteriovenous malformations(AVMs)on prior esophagogastroduodenoscopy(EGD)or colonoscopy(OR:19.30,P=0.033).Non-therapeutic DBE was associated with performing two or more DBE per day(OR:18.579,P=0.007),gastrointestinal bleeding episode within a week of the DBE(OR:11.48,P=0.003),fewer blood transfusion requirements prior to DBE(OR:4.55,P=0.036)and absence of ulcers or AVMs on prior EGD or colonoscopy(OR:8.47,P=0.027).CONCLUSION:Predictors of DBE yield and therapeutic intervention on DBE include blood transfusion requirements,previous endoscopic findings and possibly endoscopist fatigue. | Hisham Hussan Nicholas R Crews Caroline M Geremakis Soubhi Bahna Jennifer L LaBundy Christine Hachem | 2014 | World Journal of Gastrointestinal Endoscopy2014，6，6： | 3 |
| 6 | Colonoscopy quality with Entonox? vs intravenous conscious sedation:18608 colonoscopy retrospective study显示文摘AIM To compare colonoscopy quality with nitrous oxide gas(Entonox?) against intravenous conscious sedation using midazolam plus opioid.METHODS A retrospective analysis was performed on a prospectively held database of 18608 colonoscopies carried out in Lothian health board hospitals between July 2013 and January 2016.The quality of colonoscopies performed with Entonox was compared to intravenous conscious sedation(abbreviated in this article as IVM).Furthermore,the quality of colonoscopies performed with an unmedicated group was compared to IVM.The study used the following key markers of colonoscopy quality:(1) patient comfort scores;(2) caecal intubation rates(CIRs); and (3) polyp detection rates (PDRs).We used binary logistic regression to model the data.RESULTS There was no difference in the rate of moderate-toextreme discomfort between the Entonox and IVM groups (17.9% vs 18.8%; OR = 1.06,95%CI: 0.95-1.18,P = 0.27).Patients in the unmedicated group were less likely to experience moderate-to-extreme discomfort than those in the IVM group(11.4% vs 18.8%; OR = 0.71,95%CI: 0.60-0.83,P < 0.001).There was no difference in caecal intubation between the Entonox and IVM groups(94.4% vs 93.7%; OR = 1.08,95%CI: 0.92-1.28,P = 0.34).There was no difference in caecal intubation between the unmedicated and IVM groups (94.2% vs 93.7%; OR = 0.98,95%CI: 0.79-1.22,P = 0.87).Polyp detection in the Entonox group was not different from IVM group (35.0% vs 33.1%; OR = 1.01,95%CI: 0.93-1.10,P = 0.79).Polyp detection in the unmedicated group was not significantly different from the IVM group (37.4% vs 33.1%; OR = 0.97,95%CI: 0.87-1.08,P = 0.60).CONCLUSION The use of Entonox was not associated with lower colonoscopy quality when compared to intravenous conscious sedation using midazolam plus opioid. | Alexander R Robertson Nicholas A Kennedy James A Robertson Nicholas I Church Colin L Noble | 2017 | World Journal of Gastrointestinal Endoscopy2017，9，9： | 3 |

| 8 | Perioperative risk factors associated with delayed graft function following deceased donor kidney transplantation:A retrospective,single center study显示文摘BACKGROUND There is an abundant need to increase the availability of deceased donor kidney transplantation(DDKT)to address the high incidence of kidney failure.Challenges exist in the utilization of higher risk donor organs into what appears to be increasingly complex recipients;thus the identification of modifiable risk factors associated with poor outcomes is paramount.AIM To identify risk factors associated with delayed graft function(DGF).METHODS Consecutive adults undergoing DDKT between January 2016 and July 2017 were identified with a study population of 294 patients.The primary outcome was the occurrence of DGF.RESULTS The incidence of DGF was 27%.Under logistic regression,eight independent risk factors for DGF were identified including recipient body mass index≥30 kg/m^(2),baseline mean arterial pressure<110 mmHg,intraoperative phenylephrine administration,cold storage time≥16 h,donation after cardiac death,donor history of coronary artery disease,donor terminal creatinine≥1.9 mg/dL,and a hypothermic machine perfusion(HMP)pump resistance≥0.23 mmHg/mL/min.CONCLUSION We delineate the association between DGF and recipient characteristics of preinduction mean arterial pressure below 110 mmHg,metabolic syndrome,donorspecific risk factors,HMP pump parameters,and intraoperative use of phenylephrine. | Nicholas V Mendez Yehuda Raveh Joshua J Livingstone Gaetano Ciancio Giselle Guerra George W Burke III Vadim B Shatz Fouad G Souki Linda J Chen Mahmoud Morsi Jose M Figueiro Tony M Ibrahim Werviston L DeFaria Ramona Nicolau-Raducu | 2021 | World Journal of Transplantation2021，11，4： | 2 |
| 9 | Thermal hypersensitivity in a subset of irritable bowel syndrome patients显示文摘AIM:To characterize thermal hypersensitivity in patients with constipation-and diarrhea-predominant irritable bowel syndrome (IBS).METHODS:Thermal pain sensitivity was tested among patients with diarrhea-predominant IBS (D-IBS) and constipation-predominant IBS (C-IBS) compared to healthy subjects.A total of 42 patients (29 female and 13 male;mean age 27.0±6.4 years) with D-IBS;24 patients (16 female and eight male;mean age 32.5±8.8 years) with C-IBS;and 52 control subjects (34 female and 18 male;mean age 27.3±8.0 years) participated in the study.Thermal stimuli were delivered using a Medoc Thermal Sensory Analyzer with a 3 cm × 3 cm surface area.Heat pain threshold (HPTh) and heat pain tolerance (HPTo) were assessed on the left ventral forearm and left calf using an ascending method of limits.The Functional Bowel Disease Severity Index (FBDSI) was also obtained for all subjects.RESULTS:Controls were less sensitive than C-IBS and D-IBS (both at P < 0.001) with no differences between C-IBS and D-IBS for HPTh and HPTo.Thermal hyperalgesia was present in both groups of IBS patients relative to controls,with IBS patients reporting significantly lower pain threshold and pain tolerance at both test sites.Cluster analysis revealed the presence of subgroups of IBS patients based on thermal hyperalgesia.One cluster (17% of the sample) showed a profile of heat pain sensitivity very similar to that of healthy controls;a second cluster (47% of the sample) showed moderate heat pain sensitivity;and a third cluster (36% of the sample) showed a very high degree of thermal hyperalgesia.CONCLUSION:A subset of IBS patients had thermal hypersensitivity compared to controls,who reported significantly lower HPTh and HPTo.All IBS patients had a higher score on the FBDSI than controls.Interestingly,the subset of IBS patients with high thermal sensitivity (36%) had the highest FBDSI score compared to the other two groups of IBS patients. | QiQi Zhou Roger B Fillingim Joseph L Riley Ⅲ G Nicholas Verne | 2009 | World Journal of Gastroenterology2009，15，26： | 2 |

| 13 | Nitric oxide activation of a potassium channel (BK_(Ca)) in feline lower esophageal sphincter显示文摘AIM:To assess the effect of nitric oxide (NO) on the large conductance potassium channel (BKCa) in isolated circular (CM) and sling (SM) muscle cells and muscle strips from the cat lower esophageal sphincter (LES) to determine its regulation of resting tone and relaxation.METHODS:Freshly enzymatically-digested and isolated circular smooth muscle cells were prepared from each LES region.To study outward K + currents,the perforated patch clamp technique was employed.To assess LES resting tone and relaxation,muscle strips were mounted in perfused organ baths.RESULTS:(1) Electrophysiological recordings from isolated cells:(a) CM was more depolarized than SM (-39.7 ± 0.8mV vs-48.1 ± 1.6 mV,P < 0.001),and maximal outward current was similar (27.1 ± 1.5 pA/pF vs 25.7 ± 2.0 pA/pF,P > 0.05);(b) The NO donor sodium nitroprusside (SNP) increased outward currents only in CM (25.9 ± 1.9 to 46.7 ± 4.2 pA/pF,P < 0.001) but not SM (23.2 ± 3.1 to 27.0 ± 3.4 pA/pF,P > 0.05);(c) SNP added in the presence of the BK Ca antagonist iberiotoxin (IbTX) produced no increase in the outward current in CM (17.0 ± 2.8 vs 13.7 ± 2.2,P > 0.05);and (d) L-NNA caused a small insignificant inhibition of outward K + currents in both muscles;and (2) Muscle strip studies:(a) Blockade of the nerves with tetrodotoxin (TTX),or BK Ca with IbTX had no significant effect on resting tone of either muscle;and (b) SNP reduced tone in both muscles,and was unaffected by the presence of TTX or IbTX.CONCLUSION:Exogenous NO activates BK Ca only in CM of the cat.However,as opposed to other species,exogenous NO-induced relaxation is predominantly by a non-BK Ca mechanism,and endogenous NO has minimal effect on resting tone. | Marie-Claude L'Heureux Ahmad Muinuddin Herbert Y Gaisano Nicholas E Diamant | 2010 | World Journal of Gastroenterology2010，16，46： | 2 |
