1Daclatasvir plus asunaprevir in treatment-na?ve patients with hepatitis C virus genotype 1b infection显示文摘AIM To assess daclatasvir plus asunaprevir(d UAL) in treatment-na?ve patients from China's Mainland, Russia and South Korea with hepatitis C virus(HCV) genotype 1 b infection. METHODS Patients were randomly assigned(3:1) to receive 24 wk of treatment with d UAL(daclatasvir 60 mg once daily and asunaprevir 100 mg twice daily) beginning on day 1 of the treatment period(immediate treatment arm) or following 12 wk of matching placebo(placebodeferred treatment arm). The primary endpoint was a comparison of sustained virologic response at posttreatment week 12(SVR12) compared with the historical SVR rate for peg-interferon plus ribavirin(70%) among patients in the immediate treatment arm. The first 12 wk of the study were blinded. Safety was assessed in d UAL-treated patients compared with placebo patients during the first 12 wk(doubleblind phase), and during 24 wk of d UAL in both arms combined.RESULTS In total, 207 patients were randomly assigned to immediate(n = 155) or placebo-deferred(n = 52) treatment. Most patients were Asian(86%), female(59%) and aged < 65 years(90%). Among them, 13% had cirrhosis, 32% had IL28 B non-CC genotypes and 53% had baseline HCV RNA levels of ≥ 6 million IU/m L. Among patients in the immediate treatment arm, SVR12 was achieved by 92%(95% confidence interval: 87.2-96.0), which was significantly higher than the historical comparator rate(70%). SVR12 was largely unaffected by cirrhosis(89%), age ≥ 65 years(92%), male sex(90%), baseline HCV RNA ≥ 6 million(89%) or IL28 B non-CC genotypes(96%), although SVR12 was higher among patients without(96%) than among those with(53%) baseline NS5 A resistanceassociated polymorphisms(at L31 or Y93 H). during the double-blind phase, aminotransferase elevations were more common among placebo recipients than among patients receiving d UAL. during 24 wk of d UAL therapy(combined arms), the most common adverse events(≥ 10%) were elevated alanine aminotransferase and upper respiratory tract infection; emergent grade 3-4 laboratory abnormalities were infrequently observed, and all grade 3-4 aminotransferase abnormalities(alanine aminotransferase, n = 9; aspartate transaminase, n = 6) reversed within 8-11 d. Two patients discontinued d UAL treatment; one due to aminotransferase elevations, nausea, and jaundice and the other due to a fatal adverse event unrelated to treatment. There were no treatment-related deaths.CONCLUSION d UAL was well-tolerated during this phase 3 study, and SVR12 with d UAL treatment(92%) exceeded thehistorical SVR rate for peg-interferon plus ribavirin of 70%.Lai Wei Fu-Sheng Wang Ming-Xiang Zhang Ji-Dong Jia Alexey A Yakovlev Wen Xie Eduard Burnevich Jun-Qi Niu Yong Jin Jung Xiang-Jun Jiang Min Xu Xin-Yue Chen Qing Xie Jun Li Jin-Lin Hou Hong Tang Xiao-guang Dou Yash Gandhi Wen-Hua Hu Fiona McPhee Stephanie Noviello Michelle Treitel Ling Mo Jun Deng 2018World Journal of Gastroenterology2018,24,12:17

3Albumin as a prognostic marker for ulcerative colitis显示文摘AIM To evaluate the role of albumin at the time of ulcerative colitis(UC) diagnosis in predicting the clinical course of disease.METHODS Nationwide cohort of patients with newly diagnosed UC in the Veterans Affairs health care system was identified and divided into two categories: hypoalbuminemia(i.e.,≤ 3.5 gm/dl) or normal albumin levels(i.e.,> 3.5 gm/dl) at the time of UC diagnosis. The exposure of interest was presence of hypoalbuminemia defined asalbumin level ≤ 3.5 g/dl at the time of UC diagnosis. Patients were then followed over time to identify the use of ≥ 2 courses of corticosteroids(CS),thiopurines,anti-TNF medications and requirement of colectomy for UC management. RESULTS The eligible study cohort included 802 patients,but 92(11.4%) patients did not have their albumin levels checked at the time of UC diagnosis,and they were excluded. A total of 710 patients,who had albumin levels checked at time of UC diagnosis,were included in our study. Amongst them,536 patients had a normal albumin level and 174 patients had hypoalbuminemia. Patients with hypoalbuminemia at diagnosis had a higher likelihood of ≥ 2 courses of CS use(adjusted HR = 1.7,95%CI: 1.3-2.3),higher likelihood of thiopurine or anti-TNF use(adjusted HR = 1.72,95%CI: 1.23-2.40) than patients with normal albumin level at diagnosis. There was a trend of higher likelihood of colectomy in hypoalbuminemic patients,but it was not statistically significant(Adjusted HR = 1.7,95%CI: 0.90-3.25).CONCLUSION Hypoalbuminemia at disease diagnosis can serve as a prognostic marker to predict the clinical course of UC at the time of diagnosis.Nabeel Khan Dhruvan Patel Yash Shah Chinmay Trivedi Yu-Xiao Yang 2017World Journal of Gastroenterology2017,23,45:6
4Performance analysis of deep learning CNN models for disease detection in plants using image segmentation显示文摘Food security for the 7 billion people on earth requires minimizing crop damage by timely detectionofdiseases.Most deep learningmodels forautomated detectionof diseases in plants suffer fromthe fatal flaw that once tested on independent data,their performance drops significantly.This work investigates a potential solution to this problem by using segmented image data to train the convolutional neural network(CNN)models.As compared to the F-CNN model trained using full images,S-CNN model trained using segmented imagesmore than doubles in performance to 98.6%accuracy when tested on independent data previously unseen by the models even with 10 disease classes.Not only this,by using tomato plant and target spot disease type as an example,we show that the confidence of self-classification for S-CNN model improves significantly over F-CNN model.This research work brings applicability of automated methods closer to non-experts for timely detection of diseases.Parul Sharma Yash Paul Singh Berwal Wiqas Ghai 2020Information Processing in Agriculture2020,7,4:5

6Excellent tribological properties of epoxy-Ti3C2 with three-dimensional nanosheets composites显示文摘As a widely used engineering polymer,epoxy resin has been successfully employed in high-performance components and setups.However,the poor thermal and friction properties of traditional epoxy resin greatly limit its application in many extreme environments.In this work,a new kind of epoxy-Ti3C2 with three-dimensional nanosheets(3DNS)composite which was designed by freeze-drying method showed up excellent thermal and friction properties.As a result,the coefficient of thermal expansion(CTE)of epoxy-Ti3C23DNS 3.0 composites was 41.9 ppm/K at 40℃,which was lower than that of the traditional epoxy resin(46.7 ppm/K),and the thermal conductivity(TC)was also improved from 0.176 to 0.262 W/(m-K).Meanwhile,epoxy-Ti3C23DNS 1.0 composites showed up the best friction property,with wear rate 76.3%lower than that of epoxy resin.This work is significant for the research of high-performance composite materials.Fanning MENG Zhenyu ZHANG Peili GAO Ruiyang KANG Yash BOYJOO Jinhong YU Tingting LIU 2021Friction2021,9,4:3
7Healthcare utilization and costs associated with gastroparesis显示文摘AIM To use a national database of United States hospitals to evaluate the incidence and costs of hospital admissions associated with gastroparesis.METHODS We analyzed the National Inpatient Sample Database(NIS)for all patients in whom gastroparesis(ICD-9 code:536.3)was the principal discharge diagnosis during the period,1997-2013.The NIS is the largest publicly available all-payer inpatient care database in the United States.It contains data from approximately eight million hospital stays each year.The statistical significance of the difference in the number of hospital discharges,length of stay and hospital costs over the study period was determined by regression analysis.RESULTS In 1997,there were 3978 admissions with a principal discharge diagnosis of gastroparesis as compared to16460 in 2013(P<0.01).The mean length of stay for gastroparesis decreased by 20%between 1997 and 2013from 6.4 d to 5.1 d(P<0.001).However,during this period the mean hospital charges increased significantly by 159%from$13350(after inflation adjustment)per patient in 1997 to$34585 per patient in 2013(P<0.001).The aggregate charges(i.e.,'national bill') for gastroparesis increased exponentially by 1026%from$50456642±4662620 in 1997 to$568417666±22374060 in 2013(P<0.001).The percentage of national bill for gastroparesis discharges(national bill for gastroparesis/total national bill)has also increased over the last 16 years(0.0013%in 1997 vs 0.004%in2013).During the study period,women had a higher frequency of gastroparesis discharges when compared to men(1.39/10000 vs 0.9/10000 in 1997 and 5.8/10000vs 3/10000 in 2013).There was a 6-fold increase in the discharge diagnosis of gastroparesis amongst type 1 DM and 3.7-fold increase amongst type 2 DM patients over the study period(P<0.001).CONCLUSION The number of inpatient admissions for gastroparesis and associated costs have increased significantly over the last 16 years.Inpatient costs associated with gastroparesis contribute significantly to the national healthcare bill.Further research on cost-effective evaluation and management of gastroparesis is required.Vaibhav Wadhwa Dhruv Mehta Yash Jobanputra Rocio Lopez Prashanthi N Thota Madhusudhan R Sanaka 2017World Journal of Gastroenterology2017,23,24:3

14Atrial fibrillation and coronary artery disease:An integrative review focusing on therapeutic implications of this relationship显示文摘The incidence of both atrial fibrillation(AF)and coronary artery disease(CAD)increases with advancing age.They share common risk factors and very often coexist.Evidence points to an intricate relationship between atrial tissue excitability and neuronal remodeling with ischemia at the microcirculatory level.In this review,we delineated this complex relationship,identified a common theme between the two,and discussed how the knowledge of this relationship translates into a positive and meaningful impact in patient management.Recent research indicates a high prevalence of CAD among AF patients undergoing coronary angiography.Further,the incidence of AF is much higher in those suffering from CAD compared to age-matched adults without CAD underlying this reciprocal relationship.CAD adversely affects AF by promoting progression via re-entry and increasing excitability of atrial tissue as a result of ischemia and electrical inhomogeneity.AF in turn accelerates atherosclerosis via endothelial dysfunctional and inflammation and together with enhanced thrombogenicity and hypercoagulability contribute to micro and macrothrombi throughout cardiovascular system.In a nutshell,the two form a vicious cycle wherein one disease promotes the other.Most AF recommendations focuses on rate/rhythm control and prevention of thromboembolism.Very few studies have discussed the importance of unmasking coexistent CAD and how the treatment of underlying ischemia will impact the burden of AF in these patients.Inflammation and endothelial dysfunction remain central to both disease processes and form a handsome therapeutic target in the management of the two diseases.The relationship between AF and CAD is complex and much more than mere coincidence.The two diseases share common risk factor and pathophysiology.Hence,it is impractical to treat them in isolation.Accordingly,we share the implications of managing underlying ischemia and inflammation to positively impact and improve quality of life among AF patients.Akash Batta Juniali Hatwal Akshey Batta Samman Verma Yash Paul Sharma 2023World Journal of Cardiology2023,15,5:1
