| 1 | Nutrition and physical activity in NAFLD:An overview of the epidemiological evidence显示文摘Nonalcoholic fatty liver disease(NAFLD)has been recognized as a major health burden.The high prevalence of NAFLD is probably due to the contemporary epidemics of obesity,unhealthy dietary pattern,and sedentary lifestyle.The efficacy and safety profile of pharmacotherapy in the treatment of NAFLD remains uncertain and obesity is strongly associated with hepatic steatosis;therefore,the first line of treatment is lifestyle modification.The usual management of NAFLD includes gradual weight reduction and increased physical activity(PA)leading to an improvement in serum liver enzymes,reduced hepatic fatty infiltration,and,in some cases,a reduced degree of hepatic inflammation and fibrosis.Nutrition has been demonstrated to be associated with NAFLD and Non-alcoholic steatohepatitis(NASH)in both animals and humans,and thus serves as a major route of prevention and treatment.However,most human studies are observational and retrospective,allowing limited inference about causal associations.Large prospective studies and clinical trials are now needed to establish a causal relationship.Based on available data,patients should optimally achieve a 5%-10%weight reduction.Setting realistic goals is essential for long-term successful lifestyle modification and more effort must be devoted to informing NAFLD patients of the health benefits of even a modest weight reduction.Furthermore,all NAFLD patients,whether obese or of normal weight,should be informed that a healthy diet has benefits beyond weight reduction.They should be advised to reduce saturated/trans fat and increase polyunsaturated fat,with special emphasize on omega-3 fatty acids.They should reduce added sugar to its minimum,try to avoid soft drinks containing sugar,including fruit juices that contain a lot of fructose,and increase their fiber intake.For the heavy meat eaters,especially those of red and processed meats,less meat and increased fish intake should be recommended.Minimizing fast food intake will also help maintain a healthy diet.PA should be integrated into behavioral therapy in NAFLD,as even small gains in PA and fitness may have significant health benefits.Potentially therapeutic dietary supplements are vitamin E and vitamin D,but both warrant further research.Unbalanced nutrition is not only strongly associated with NAFLD,but is also a risk factor that a large portion of the population is exposed to.Therefore,it is important to identify dietary patterns that will serve as modifiable risk factors for the prevention of NAFLD and its complications. | Shira Zelber-Sagi Ran Oren Zelber-Sagi Vlad Ratziu | 2011 | World Journal of Gastroenterology2011，17，29： | 33 |
| 2 | Effect of resistance training on non-alcoholic fatty-liver disease a randomized-clinical trial显示文摘AIM:To evaluate the effect of resistance training(RT)on non alcoholic liver disease(NAFLD)patients.METHODS:A randomized clinical trial enrolling NAFLD patients without secondary liver disease(e.g.,without hepatitis B virus,hepatitis C virus or excessive alcohol consumption).Patients were randomly allocated either to RT,three times weekly,for 3 mo or a control arm consisting of home stretching.The RT included leg press,chest press,seated rowing,latissimus pull down etc.with 8-12 repetitions,3 sets for each exercise,for a total duration of 40 min.Hepatic ultrasound,fasting blood tests,anthropometrics and body composition by dual energy X-ray absorptiometry were assessed.At baseline and follow-up,patients filled out a detailed semi-quantitative food frequency questionnaire reporting their habitual nutritional intake.Steatosis was quantified by the hepatorenal-ultrasound index(HRI)representing the ratio between the brightness level of the liver and the right kidney.The HRI has been previously demonstrated to be highly reproducible and was validated against liver biopsy and proton magnetic resonance spectroscopy.RESULTS:Eighty two patients with primary NAFLD were randomized to receive 3 mo of either RT or stretching.After dropout or exclusion from analysis because of protocol violation(weight change>3 kg),thirty three patients in the RT arm and 31 in the stretching arm completed the study per protocol.All baseline characteristics were similar for the two treatment groups with respect to demographics,anthropometrics and body composition,blood tests and liver steatosis on imaging.HRI score was reduced significantly in the RT arm as compared to the stretching arm(-0.25±0.37 vs-0.05±0.28,P=0.017).The RT arm had a significantly higher reduction in total,trunk and android fat with increase in lean body mass.There was no correlation between the reduction in HRI in the RT arm and weight change during the study,but it was positively correlated with the change in trunk fat(r=0.37,P=0.048).The RT arm had a significant reduction in serum ferritin and total cholesterol.There was no significant difference between arms in dietary changes and these did not correlate with HRI change.CONCLUSION:Three months RT improves hepatic fat content accompanied by favorable changes in body composition and ferritin.RT may serve as a complement to treatment of NAFLD. | Shira Zelber-Sagi Assaf Buch Hanny Yeshua Nahum Vaisman Muriel Webb Gil Harari Ofer Kis Naomi Fliss-Isakov Elena Izkhakov Zamir Halpern Erwin Santo Ran Oren Oren Shibolet | 2014 | World Journal of Gastroenterology2014，20，15： | 17 |
| 3 | Nutritional issues in patients with obesity and cirrhosis显示文摘Obesity and metabolic syndrome are considered as responsible for a condition known as the non-alcoholic fatty liver disease that goes from simple accumulation of triglycerides to hepatic inflammation and may progress to cirrhosis.Patients with obesity also have an increased risk of primary liver malignancies and increased body mass index is a predictor of decompensation of liver cirrhosis.Sarcopenic obesity confers a risk of physical impairment and disability that is significantly higher than the risk induced by each of the two conditions alone as it has been shown to be an independent risk factor for chronicliver disease in patients with obesity and a prognostic negative marker for the evolution of liver cirrhosis and the results of liver transplantation.Cirrhotic patients with obesity are at high risk for depletion of various fat-soluble,water-soluble vitamins and trace elements and should be supplemented appropriately.Diet,physical activity and protein intake should be carefully monitored in these fragile patients according to recent recommendations.Bariatric surgery is sporadically used in patients with morbid obesity and cirrhosis also in the setting of liver transplantation.The risk of sarcopenia,micronutrient status,and the recommended supplementation in patients with obesity and cirrhosis are discussed in this review.Furthermore,the indications and contraindications of bariatric surgery-induced weight loss in the cirrhotic patient with obesity are discussed. | Luigi Schiavo Luca Busetto Manuela Cesaretti Shira Zelber-Sagi Liat Deutsch Antonio Iannelli | 2018 | World Journal of Gastroenterology2018，24，30： | 9 |
| 4 | Comparison of fatty liver index with noninvasive methods for steatosis detection and quantification显示文摘AIM:To compare noninvasive methods presently used for steatosis detection and quantification in nonalcoholic fatty liver disease(NAFLD).METHODS:Cross-sectional study of subjects from the general population,a subgroup from the First Israeli National Health Survey,without excessive alcohol consumption or viral hepatitis.All subjects underwent anthropometric measurements and fasting blood tests.Evaluation of liver fat was performed using four noninvasive methods:the SteatoTest;the fatty liver index(FLI);regular abdominal ultrasound(AUS);and the hepatorenal ultrasound index(HRI).Two of the noninvasive methods have been validated vs liver biopsy and were considered as the reference methods:the HRI,the ratio between the median brightness level of the liver and right kidney cortex;and the SteatoTest,a biochemical surrogate marker of liver steatosis.The FLI is calculated by an algorithm based on triglycerides,body mass index,γ-glutamyl-transpeptidase and waist circumference,that has been validated only vs AUS.FLI < 30 rules out and FLI ≥ 60 rules in fatty liver.RESULTS:Three hundred and thirty-eight volunteers met the inclusion and exclusion criteria and had valid tests.The prevalence rate of NAFLD was 31.1% according to AUS.The FLI was very strongly correlated with SteatoTest(r = 0.91,P < 0.001) and to a lesser but significant degree with HRI(r = 0.55,P < 0.001).HRI and SteatoTest were significantly correlated(r = 0.52,P < 0.001).The κ between diagnosis of fatty liver by SteatoTest(≥ S2) and by FLI(≥ 60) was 0.74,which represented good agreement.The sensitivity of FLI vs SteatoTest was 85.5%,specificity 92.6%,positive predictive value(PPV) 74.7%,and negative predictive value(NPV) 96.1%.Most subjects(84.2%) with FLI < 60 had S0 and none had S3-S4.The κ between diagnosis of fatty liver by HRI(≥ 1.5) and by FLI(≥ 60) was 0.43,which represented only moderate agreement.The sensitivity of FLI vs HRI was 56.3%,specificity 86.5%,PPV 57.0%,and NPV 86.1%.The diagnostic accuracy of FLI for steatosis > 5%,as predicted by SteatoTest,yielded an area under the receiver operating characteristic curve(AUROC) of 0.97(95% CI:0.95-0.98).The diagnostic accuracy of FLI for steatosis> 5%,as predicted by HRI,yielded an AUROC of 0.82(95% CI:0.77-0.87).The κ between diagnosis of fatty liver by AUS and by FLI(≥ 60) was 0.48 for the entire sample.However,after exclusion of all subjects with an intermediate FLI score of 30-60,the κ between diagnosis of fatty liver by AUS and by FLI either ≥ 60 or < 30 was 0.65,representing good agreement.Excluding all the subjects with an intermediate FLI score,the sensitivity of FLI was 80.3% and the specificity 87.3%.Only 8.5% of those with FLI < 30 had fatty liver on AUS,but 27.8% of those with FLI ≥ 60 had normal liver on AUS.CONCLUSION:FLI has striking agreement with SteatoTest and moderate agreements with AUS or HRI.However,if intermediate values are excluded FLI has high diagnostic value vs AUS. | Shira Zelber-Sagi Muriel Webb Nimer Assy Laurie Blendis Hanny Yeshua Moshe Leshno Vlad Ratziu Zamir Halpern Ran Oren Erwin Santo | 2013 | World Journal of Gastroenterology2013，19，1： | 8 |
| 5 | Role of illness perception and self-efficacy in lifestyle modification among non-alcoholic fatty liver disease patients显示文摘AIM To describe the relationships between non-alcoholic fatty-liver disease(NAFLD) patient's disease consequences and treatment perceptions, self-efficacy, and healthy lifestyle maintenance. METHODS A cross-sectional study among 146 ultrasound diagnosed NAFLD patients who visited the fatty liver clinic at the TelAviv Medical Center. Eighty-seven of these individuals, participated in a clinical trial of physical activity and underwent fasting blood tests, analyzed at the same lab. Exclusion criteria included positivity for serum HBsA g or anti-HCV antibodies; fatty liver suspected to be secondary to hepatotoxic drugs; excessive alcohol consumption(≥ 30 g/d in men or ≥ 20 g/d in women) and positive markers of genetic or immune-mediated liver diseases. Patients were asked to complete a selfreport structured questionnaire, assembled by the Israeli Center for Disease Control. Nutrition habits were measured using six yes/no questions(0 = no, 1 = yes) adopted from the national survey questionnaire. Participants in the clinical trial completed a detailed semi-quantitative food frequency questionnaire(FFQ) reporting their habitual nutritional intake during the past year. Self-efficacy was assessed by the Self-Efficacy Scale questionnaire, emotional representation, degree of illness understanding, timeline perception, treatment perception and symptoms were measured by the Brief Illness Perception questionnaire. Illness consequences were measured by the Personal Models of Diabetes Interview questionnaire. A path analysis was performed to describe the interrelationships between the patients' illness perceptions, and assess the extent to which the data fit a prediction of nutritional habits.RESULTS The study sample included 54.1% men, with a mean age of 47.76 ± 11.68 years(range: 20-60) and mean body mass index of 31.56 ± 4.6. The average perceived nutrition habits score was 4.73 ± 1.45 on a scale between 0-6, where 6 represents the healthiest eating habits. Most of the study participants(57.2%) did not feel they fully understood what NAFLD is. Better nutritional habits were positively predicted by the degree of illness understanding(β = 0.26; P = 0.002) and selfefficacy(β = 0.25; P = 0.003). Perceptions of more severe illness consequences were related with higher emotional representation(β = 0.55; P < 0.001), which was related with lower self-efficacy(β =-0.17; P = 0.034). The perception of treatment effectiveness was positively related with self-efficacy(β = 0.32; P < 0.001). In accordance with the correlation between self-efficacy and the perceived nutrition habits score, self-efficacy was also correlated with nutrient intake evaluated by the FFQ; negatively with saturated fat(percent of saturated fat calories from total calories)(r =-0.28, P = 0.010) and positively with fiber(r = 0.22, P = 0.047) and vitamin C intake(r = 0.34, P = 0.002). In a sub analysis of the clinical trial participants, objectively measured compliance to physical activity regimen was positively correlated with the self-efficacy level(r = 0.34, P = 0.046). CONCLUSION Self-efficacy and illness understanding are major determinants of lifestyle-modification among NAFLD patients. This information can assist clinicians in improving compliance with lifestyle changes among these patients. | Shira Zelber-Sagi Shiran Bord Gali Dror-Lavi Matthew Lee Smith Samuel D Towne Jr Assaf Buch Muriel Webb Hanny Yeshua Assy Nimer Oren Shibolet | 2017 | World Journal of Gastroenterology2017，23，10： | 6 |

| 8 | Mediterranean dietary components are inversely associated with advanced colorectal polyps:A case-control study显示文摘AIM To evaluate the association between the Mediterranean diet(MD) pattern and its components, and advanced colorectal polyps(adenoma and serrated adenoma).METHODS A case-control study among patients undergoing screening, diagnostic or surveillance colonoscopies during 2010-2015 at the Tel-Aviv Medical Center, Gastroenterology Department. Cases with advanced polyps were defined as: Advanced adenoma [> 10 mm, with features of high grade dysplasia(HGD) or villous histology], advanced serrated adenoma(> 10 mm or with dysplasia) or multiple(≥ 3) non-advanced adenomas or serrated adenomas. Cases of non-advanced adenomas were defined as adenomas < 10 mm, without features of HGD or villous histology. Controls were defined as those without polyps at the current colonoscopy and without a history of colorectal polyps. Data collection included: anthropometrics measured according to a standardized protocol, fasting blood tests performed at the same lab, medical history recorded by a structured interview and dietary intake evaluated by a 116-item food frequency questionnaire. Adherence to the MD components was evaluated according to intake above/below the sample median, for potentially beneficial/detrimental components respectively, as accepted. RESULTS We recruited 206 cases with advanced polyps, 192 cases with non-advanced adenoma and 385 controls. The number of adhered MD components was inversely associated with a diagnosis of advanced polyps in a dose-response manner(OR = 0.34, 95%CI: 0.17-0.65; OR = 0.22, 95%CI: 0.11-0.43; and OR = 0.18, 95%CI: 0.07-0.47 for 3-4, 5-7 and 8-10 components, respectively), but not with non-advanced adenomas(OR = 0.54, 95%CI: 0.25-1.13; OR = 0.48, 95%CI: 0.23-0.99; and OR = 0.43, 95%CI: 0.16-1.12 for 3-4, 5-7 and 8-10 components, respectively). Low intake of sugar-sweetened beverages and red meat, as well as high intake of fish, were inversely associated with advanced polyps(OR = 0.56, 95%CI: 0.36-0.87; OR = 0.63, 95%CI: 0.42-0.95; and OR = 0.66, 95%CI: 0.44-0.99, respectively), while only low intake of red meat was inversely associated with non-advanced adenomas(OR = 0.71, 95%CI: 0.49-0.97). CONCLUSION A better adherence to the MD, specifically low intake of sugar-sweetened beverages and red meat as well as high intake of fish, is related to lower odds for advanced polyps. | Naomi Fliss-Isakov Revital Kariv Muriel Webb Dana Ivancovsky Dana Margalit Shira Zelber-Sagi | 2018 | World Journal of Gastroenterology2018，24，24： | 3 |
| 9 | Longitudinal decrease in platelet counts as a surrogate marker of liver fibrosis显示文摘BACKGROUND Liver cirrhosis is a significant source of morbidity and mortality worldwide.The disease is usually indolent and asymptomatic early in its course while many cirrhotic patients are diagnosed late when severe complications occur.A major challenge is to diagnose advanced fibrosis as early as possible,using simple and non-invasive diagnostics tools.Thrombocytopenia represents advanced fibrosis and portal hypertension(HTN)and most non-invasive scores that predict liver fibrosis incorporate platelets as a strong risk factor.However,little is known about the association between longitudinal changes in platelet counts(PTC),when still within the normal range,and the risk of cirrhosis.AIM To explore whether platelet counts trajectories over time,can predict advanced liver fibrosis across the different etiologies of liver diseases.METHODS A nested case-control study utilizing a large computerized database.Cirrhosis cases(n=5258)were compared to controls(n=15744)matched for age and sex at a ratio of 1:3.All participants had multiple laboratory measurements prior to enrollment.We calculated the trends of PTC,liver enzymes,bilirubin,international normalized ratio,albumin and fibrosis scores(fibrosis-4 and aspartate transaminase-to-platelet ratio index)throughout the preceding 20 years prior to cirrhosis diagnosis compared to healthy controls.The association between PTC,cirrhosis complications and fibrosis scores prior to cirrhosis diagnosis was investigated.RESULTS The mean age in both groups was 56(SD 15.8).Cirrhotic patients were more likely to be smokers,diabetic with chronic kidney disease and had a higher prevalence of HTN.The leading cirrhosis etiologies were viral,alcoholic and fatty liver disease.The mean PTC decreased from 240000/μL to 190000/μL up to 15 years prior to cirrhosis diagnosis compared to controls who’s PTC remained stable around the values of 240000/μL.This trend was consistent regardless of sex,cirrhosis etiology and was more pronounced in patients who developed varices and ascites.Compared to controls whose values remained in the normal range,in the cirrhosis group aspartate aminotransferase and alanine aminotransferase,increased from 40 U/L to 75 U/L and FIB-4 increased gradually from 1.3 to 3 prior to cirrhosis diagnosis.In multivariable regression analysis,a decrease of 50 units in PTC was associated with 1.3 times odds of cirrhosis(95%CI 1.25-1.35).CONCLUSION In the preceding years before the diagnosis of cirrhosis,there is a progressive decline in PTC,within the normal range,matched to a gradual increase in fibrosis scores. | Neta Gotlieb Naama Schwartz Shira Zelber-Sagi Gabriel Chodick Varda Shalev Oren Shibolet | 2020 | World Journal of Gastroenterology2020，26，38： | 3 |

| 12 | Moro orange juice prevents fatty liver in mice显示文摘AIM:To establish if the juice of Moro,an anthocyaninrich orange,may improve liver damage in mice with diet-induced obesity.METHODS:Eight-week-old mice were fed a high-fat diet(HFD) and were administrated water or Moro juice for 12 wk.Liver morphology,gene expression of lipid transcription factors,and metabolic enzymes were assessed.RESULTS:Mice fed HFD displayed increased body weight,insulin resistance and dyslipidemia.Moro juice administration limited body weight gain,enhanced insulin sensitivity,and decreased serum triglycerides and total cholesterol.Mice fed HFD showed liver steatosis associated with ballooning.Dietary Moro juice markedly improved liver steatosis by inducing the expression of peroxisome proliferator-activated receptor-α and its target gene acylCoA-oxidase,a key enzyme of lipid oxidation.Consistently,Moro juice consumption suppressed the expression of liver X receptor-α and its target gene fatty acid synthase,and restored liver glycerol-3-phosphate acyltransferase 1 activity.CONCLUSION:Moro juice counteracts liver steatogenesis in mice with diet-induced obesity and thus may represent a promising dietary option for the prevention of fatty liver. | Federico Salamone Giovanni Li Volti Lucilla Titta Lidia Puzzo Ignazio Barbagallo Francesco La Delia Shira Zelber-Sagi Michele Malaguarnera Pier Giuseppe Pelicci Marco Giorgio Fabio Galvano | 2012 | World Journal of Gastroenterology2012，18，29： | 2 |

| 14 | Increased fibrosis progression rates in hepatitis C patients carrying the prothrombin G20210A mutation显示文摘AIM: To examine whether hepatitis C virus (HCV)-infected patients who carry hypercoagulable mutationssuffer from increased rates of liver fi brosis. METHODS: We analyzed DNA samples of 168 HCV patients for three common hypercoagulable gene mutations: prothrombin 20210 (PT20210), factor V Leiden (FV Leiden) and methylene tetrahydrofolate reductase (MTHFR). The patients were consecutively recruited as part of the prospective 'Fibroscore Study' in France. The effect of the various mutations on the rate of fi-brosis was analyzed statistically and was correlated with epidemiological, clinical and biochemical data such as grade and stage of liver biopsies, patients' risk factors for liver cirrhosis, and timing of infection. RESULTS: Fifty two of the patients were categorized as 'fast fi brosers' and 116 as 'slow fi brosers'; 13% of the 'fast fi brosers' carried the PT20210 mutation as compared with 5.5% of the 'slow fi brosers', with an odds ratio of 4.76 (P = 0.033; 95% CI: 1.13-19.99) for 'fast' liver fibrosis. Carriage of MTHFR or FV Leiden mutations was not associated with enhanced liver fi brosis. CONCLUSION: Carriage of the PT20210 mutation is related to an increased rate of liver fi brosis in HCV patients. | Nitsan Maharshak Philippe Halfon Varda Deutsch Hava Peretz Shlomo Berliner Sigal Fishman Shira Zelber-Sagi Uri Rozovski Moshe Leshno Ran Oren | 2011 | World Journal of Gastroenterology2011，17，45： | 2 |

| 16 | Removing Moisture Effect on Soil Reflectance Properties: A Case Study of Clay Content Prediction显示文摘Visible, near-infrared and shortwave-infrared(VNIR-SWIR) spectroscopy is an efficient approach for predicting soil properties because it reduces the time and cost of analyses. However, its advantages are hampered by the presence of soil moisture, which masks the major spectral absorptions of the soil and distorts the overall spectral shape. Hence, developing a procedure that skips the drying process for soil properties assessment directly from wet soil samples could save invaluable time. The goal of this study was twofold:proposing two approaches, partial least squares(PLS) and nearest neighbor spectral correction(NNSC), for dry spectral prediction and utilizing those spectra to demonstrate the ability to predict soil clay content. For these purposes, we measured 830 samples taken from eight common soil types in Israel that were sampled at 66 different locations. The dry spectrum accuracy was measured using the spectral angle mapper(SAM) and the average sum of deviations squared(ASDS), which resulted in low prediction errors of less than 8% and 14%, respectively. Later, our hypothesis was tested using the predicted dry soil spectra to predict the clay content, which resulted in R^2 of 0.69 and 0.58 in the PLS and NNSC methods, respectively. Finally, our results were compared to those obtained by external parameter orthogonalization(EPO) and direct standardization(DS). This study demonstrates the ability to evaluate the dry spectral fingerprint of a wet soil sample, which can be utilized in various pedological aspects such as soil monitoring, soil classification,and soil properties assessment. | Yaron OGEN Shira FAIGENBAUM-GOLOVIN Amihai GRANOT Yoel SHKOLNISKY Naftaly GOLDSHLEGER Eyal BEN-DOR | 2019 | Pedosphere2019，29，4： | 2 |
| 17 | Barrett's esophagus with high grade dysplasia is associated with non-esophageal cancer显示文摘AIM To study factors associated with esophageal and nonesophageal cancer morbidity among Barrett's esophagus(BE) patients. METHODS A cohort study within a single tertiary center included 386 consecutive patients with biopsy proven BE, who were recruited between 2004-2014. Endoscopic and histologic data were prospectively recorded. Cancer morbidity was obtained from the national cancer registry. Main outcomes were BE related(defined as esophagus and cardia) and non-BE related cancers(all other cancers). Cancer incidence and all-causemortality were compared between patients with highgrade dysplasia(HGD) and with low-grade or no dysplasia(non-HGD) using Kaplan-Meier curves and cox regression models.RESULTS Of the 386 patients, 12 had HGD, 7 had a BE related cancer. There were 75(19.4%) patients with 86 cases of lifetime cancers, 76 of these cases were non-BE cancers. Seven(1.8%) and 18(4.7%) patients had BE and non-BE incident cancers, respectively. Twelve(3.1%) patients had HGD as worst histologic result. Two(16.7%) and 16(4.4%) incident non-BE cancers occurred in the HGD and non-HGD group, respectively. Ten-year any cancer and non-BE cancer free survival was 63% and 82% in the HGD group compared to 93% and 95% at the non-HGD group, respectively. Log-rank test for patients with more than one endoscopy, assuring longer follow up, showed a significant difference(P < 0.001 and P = 0.017 respectively). All-cause mortality was not significantly associated with BE HGD.CONCLUSION Patients with BE and HGD, may have a higher risk for all-cause cancer morbidity. The implications on cancer prevention recommendations should be further studied. | Nir Bar Naama Schwartz Michal Nissim Naomi Fliss-Isacov Shira Zelber-Sagi Revital Kariv | 2018 | World Journal of Gastroenterology2018，24，39： | 2 |
