1Acute alcoholic hepatitis, end stage alcoholic liver disease and liver transplantation: An Italian position statement显示文摘Alcoholic liver disease encompasses a broad spectrum of diseases ranging from steatosis steatohepatitis,fibrosis,and cirrhosis to hepatocellular carcinoma.Forty-four per cent of all deaths from cirrhosis are attributed to alcohol.Alcoholic liver disease is the second most common diagnosis among patients undergoing liver transplantation(LT).The vast majority of transplant programmes(85%)require 6 mo of abstinence prior to transplantation;commonly referred to as the'6-mo rule'.Both in the case of progressive end-stage liver disease(ESLD)and in the case of severe acute alcoholic hepatitis(AAH),not responding to medical therapy,there is a lack of evidence to support a 6-mo sobriety period.It is necessary to identify other risk factors that could be associated with the resumption of alcohol drinking.The'Group of Italian Regions'suggests that:in a case of ESLD with model for end-stage liver disease<19 a 6-mo abstinence period is required;in a case of ESLD,a 3-mo sober period before LT may be more ideal than a 6-mo period,in selected patients;and in a case of severe AAH,not respond-ing to medical therapies(up to 70%of patients die within 6 mo),LT is mandatory,even without achieving abstinence.The multidisciplinary transplant team must include an addiction specialist/hepato-alcohologist.Patients have to participate in self-help groups.Gianni Testino Patrizia Burra Ferruccio Bonino Francesco Piani Alessandro Sumberaz Roberto Peressutti Andrea Giannelli Castiglione Valentino Patussi Tiziana Fanucchi Ornella Ancarani Giovanna De Cerce Anna Teresa Iannini Giovanni Greco Antonio Mosti Marilena Durante Paola Babocci Mariano Quartini Davide Mioni Sarino Aricò Aniello Baselice Silvia Leone Fabiola Lozer Emanuele Scafato Paolo Borro 2014World Journal of Gastroenterology2014,20,40:5

3Comparison Between Deep Learning Models and Traditional Machine Learning Approaches for Facial Expression Recognition in Ageing Adults显示文摘Facial expression recognition is one'of the most active areas of research in computer vision since one of the non-verbal communication methods by which one understands the lnood/mental state of a person is the expression of face.Thus,it has been used in various fields such as human-robot interaction,security,computer graphics animation,and ambient assistance.Nevertheless,it remains a challenging task since existing approaches lack generalizability and almost all studies ignore the effects of facial attributes,such as age.oil expression recognition even though the research indicates that facial expression inanifestation varies with age.Recently,a lot of progress has been made in this topic and great improvements in classification task were achieved with the emergence of deep learning methods.Such approaches have sliown how hierarchies of features can be directly learned from original data,thus avoiding classical hand designed feature extraction methods that generally rely on manual operations witli labelled data.However,research papers systematically exploring tlu4 performance of existing deep architectures for the task of classifying expression of ageing adults are absent in the literature.In the present work a tentative to try this gap is done considering the performance of three recent deep convolutiorial neural networks models(VGG-16,AlexNet and GoogLeNet/Inception V1)and evaluating it on four different benchmark datcisets(FACES,Lifespan,CIFE,and FER2013)which also contain facial expressions performed by elderly subjects.As the baseline,and with the aim of making a comparison,two traditional inacliine learning approaches based on handcrafted features extraction process are evaluated on the same datasets.Carrying out an exhaustive and rigorous experimentation focused on the concept of 'transfer learning',which consists of replacing the output level of the deep architectures considered with new output levels appropriate to the number of classes(facial expressions),and training three different classifiers(i.e.,Random Forest,Support Vector Macliine and Linear Regression),VGG-16 deep architecture in combination with Random Forest classifier was found to be the best in terms of accuracy for eacli dataset and for each considered age-group,Moreover,the experinientation stage showed that the deep learning approacli significantly improves the baseline approaches considered,and the most noticeable improvement was obtained when considering facial expressions of ageing adults.Andrea Caroppo Alessandro Leone Pietro Siciliano 2020Journal of Computer Science & Technology2020,35,5:2

19An evaluation of intraoperative and postoperative outcomes of torsional mode versus longitudinal ultrasound mode phacoemulsification:a Meta-analysis显示文摘AIM: To evaluate and compare the intraoperative parameters and postoperative outcomes of torsional mode and longitudinal mode of phacoemulsification. METHODS: Pertinent studies were identified by a computerized MEDLINE search from January 2002 to September 2013. The Meta-analysis is composed of two parts. In the first part the intraoperative parameters were considered: ultrasound time(UST) and cumulative dissipated energy(CDE). The intraoperative values were also distinctly considered for two categories(moderate and hard cataract group) depending on the nuclear opacity grade. In the second part of the study the postoperative outcomes as the best corrected visual acuity(BCVA) and the endothelial cell loss(ECL) were taken in consideration.RESULTS: The UST and CDE values proved statistically significant in support of torsional mode for both moderate and hard cataract group. The analysis of BCVA did not present statistically significant difference between the two surgical modalities. The ECL count was statistically significant in support of torsional mode(P <0.001). CONCLUSION: The Meta-analysis shows the superiority of the torsional mode for intraoperative parameters(UST, CDE) and postoperative ECL outcomes.Pia Leon Ingrid Umari Alessandro Mangogna Andrea Zanei Daniele Tognetto 2016International Journal of Ophthalmology(English edition)2016,9,6:1
