| 1 | Development of an Arabic version of the National Eye Institute Visual Function Questionnaire as a tool to study eye diseases patients in Egypt显示文摘AIM:To develop and test an Arabic version of the National Eye Institute Visual Function Questionnaire-25(NEI-VFQ-25).METHODS:NEI-VFQ-25 was translated into Arabic according to WHO translation guidelines. We enrolled adult consenting patients with bilateral chronic eye diseases who presented to 14 hospitals across Egypt from October to December 2012, and documented their clinical findings. Psychometric properties were then tested using STATA.RESULTS:We recruited 379 patients, whose mean age was(54.5±15)y. Of 46.2% were males, 227 had cataract,31 had glaucoma, 23 had retinal detachment, 37 had diabetic retinopathy, and 61 had miscellaneous visual defects. Non-response rate and the floor and ceiling numbers of the Arabic version(ARB-VFQ-25) were calculated. Internal consistency was high in all subscales(except general health), with Cronbach-α ranging from0.702-0.911. Test-retest reliability was high(intraclass correlation coefficient 0.79).CONCLUSION:RB-VFQ-25 isareliableandvalidtool for assessing visual functions of Arabic speaking patients. However, some questions had high non-response rates and should be substituted by available alternatives. Our results support the importance of including self-reported visual functions as part of routine ophthalmologic examination. | Nizar Saleh Abdelfattah Mohamed Amgad Ahmed A Salama Marina E Israel Ghada A Elhawary Ahmed E Radwan Mohamed M Elgayar Tamer M EL Nakhal Islam T Elkhateb Heba A Hashem Doha K Embaby Amira A Elabd Reem K Elwy Magdi S Yacoub Hamdy Salem Mohamed Abdel-Baqy Ahmad Kassem | 2014 | International Journal of Ophthalmology(English edition)2014，7，5： | 8 |
| 2 | Novel non-invasive biological predictive index for liver fibrosis in hepatitis C virus genotype 4 patients显示文摘AIM To investigate the diagnostic ability of a non-invasive biological marker to predict liver fibrosis in hepatitis C genotype 4 patients with high accuracy.METHODS A cohort of 332 patients infected with hepatitis C genotype 4 was included in this cross-sectional study. Fasting plasma glucose, insulin, C-peptide, and angiotensinconverting enzyme serum levels were measured. Insulin resistance was mathematically calculated using the homeostasis model of insulin resistance(HOMA-IR).RESULTS Fibrosis stages were distributed based on Metavir score as follows: F0 = 43, F1 = 136, F2 = 64, F3 = 45 and F4 = 44. Statistical analysis relied upon reclassification of fibrosis stages into mild fibrosis(F0-F) = 179, moderate fibrosis(F2) = 64, and advanced fibrosis(F3-F4) = 89. Univariate analysis indicated that age, log aspartate amino transaminase, log HOMA-IR and log platelet count were independent predictors of liver fibrosis stage(P < 0.0001). A stepwise multivariate discriminant functional analysis was used to drive a discriminative model for liver fibrosis. Our index used cut-off values of ≥ 0.86 and ≤-0.31 to diagnose advanced and mild fibrosis, respectively, with receiving operating characteristics of 0.91 and 0.88, respectively. The sensitivity, specificity, positive predictive value, negative predictive value and positive likelihood ratio were: 73%, 91%, 75%, 90% and 8.0 respectively for advanced fibrosis, and 67%, 88%, 84%, 70% and 4.9, respectively, for mild fibrosis.CONCLUSION Our predictive model is easily available and reproducible, and predicted liver fibrosis with acceptable accuracy. | Mahmoud Khattab Mohamed Amin Sakr Mohamed Abdel Fattah Youssef Mousa Elwy Soliman Ashraf Breedy Mona Fathi Salwa Gaber Ahmed Altaweil Ashraf Osman Ahmed Hassouna Ibrahim Motawea | 2016 | World Journal of Hepatology2016，8，32： | 2 |

| 4 | 重型采矿设备的疲劳寿命预测第一部分:疲劳荷载评估和裂纹发展速度试验显示文摘重型采矿设备的疲劳寿命预测十分重要。首先,对早已存在有慢性疲劳裂纹的铲矿机起动臂进行现场监测,从监测数据中归纳了吊杆的载荷范围。针对试验数据,建立吊杆的有限元模型来预测其压应力和应变。进行了8个裂纹发展速度试验,获得使用材料的疲劳特性。基于Palmgren-Miner’s累积损坏原则和裂纹发展速度的试验结果,计算出恒振幅的换算应力范围。 | G.Y. Grondin K.H. Obaia A.E. Elwi | 2008 | 钢结构2008，23，6： | 2 |
