| 1 | Influence of vitamin D on liver fibrosis in chronic hepatitis C: A systematic review and meta-analysis of the pooled clinical trials data显示文摘AIM To investigate the relationship between vitamin D and liver fibrosis in hepatitis C-monoinfected or hepatitis C virus(HCV)-human immunodeficiency virus(HIV) coinfected patients. METHODS Pertinent studies were located by a library literature search in PubM ed/Embase/Cochrane/Scopus/LILACS by two individual reviewers. Inclusion criteria:(1) studies with patients with HCV or co-infected HCV/HIV;(2) studies with patients ≥ 18 years old;(3) studies that evaluated liver fibrosis stage, only based on liver biopsy; and(4) studies that reported serum or plasma 25(OH)D levels. Studies that included pediatric patients, other etiologies of liver disease, or did not use liver biopsy for fibrosis evaluation, or studies with inadequate data were excluded. Estimated measures of association reported in the literature, as well as corresponding measures of uncertainty, were recorded and corresponding odds ratios with 95%CI were included in a meta-analysis. RESULTS The pooled data of this systematic review showed that 9 of the 12 studies correlated advanced liver disease defined as a Metavir value of F3/4 with 25(OH) D level insufficiency. The meta-analysis indicated a significant association across studies.CONCLUSION Low vitamin D status is common in chronic Hepatitis C patients and is associated with advanced liver fibrosis. | Alia S Dadabhai Behnam Saberi Katie Lobner Russell T Shinohara Gerard E Mullin | 2017 | World Journal of Hepatology2017，9，5： | 6 |
| 2 | Transjugular intrahepatic portosystemic stent shunt for medically refractory hepatic hydrothorax:A systematic review and cumulative meta-analysis显示文摘AIM:To assess the effectiveness of transjugular intrahepatic portosystemic stent shunt(TIPSS) in refractory hepatic hydrothorax(RHH) in a systematic review and cumulative meta-analysis.METHODS:A comprehensive literature search was conducted on MEDLINE,EMBASE,and Pub Med covering the period from January 1970 to August 2014.Two authors independently selected and abstracted data from eligible studies.Data were summarized using a random-effects model.Heterogeneity was assessed using the I2 test.RESULTS:Six studies involving a total of 198 patients were included in the analysis.The mean(SD) age of patients was 56(1.8) years.Most patients(56.9%) had Child-Turcott-Pugh class C disease.The mean duration of follow-up was 10 mo(range,5.7-16 mo).Response to TIPSS was complete in 55.8%(95%CI:44.7%-66.9%),partial in 17.6%(95%CI:10.9%-24.2%),and absent in 21.2%(95%CI:14.2%-28.3%).The mean change in hepatic venous pressure gradient post-TIPSS was 12.7 mm Hg.The incidence of TIPSS-related encephalopathy was 11.7%(95%CI:6.3%-17.2%),and the 45-d mortality was 17.7%(95%CI:11.34%-24.13%).CONCLUSION:TIPSS is associated with a clinically relevant response in RHH.TIPSS should be considered early in these patients,given its poor prognosis. | Ivo C Ditah Badr F Al Bawardy Behnam Saberi Chobufo Ditah Patrick S Kamath | 2015 | World Journal of Hepatology2015，7，13： | 5 |
| 3 | Vitamin D levels do not predict the stage of hepatic fibrosis in patients with non-alcoholic fatty liver disease: A PRISMA compliant systematic review and meta-analysis of pooled data显示文摘AIM To investigate the relationship between 25-hydroxyvitamin D [25(OH)D] levels and fibrosis stage in patients with non-alcoholic fatty liver disease(NAFLD).METHODS Two individual reviewers identified relevant studies using the Pub Med, EMBASE, Cochrane, and Scopus databases. Inclusion criteria were as follows:(1) Studies that evaluated adults with NAFLD and serum or plasma 25(OH)D levels; and(2) assessed fibrosis stage using liver biopsy. A rigorous analysis yielded six articles as having sufficient data to employ in evaluating the association of serum vitamin D levels in patients with NAFLD based on their liver fibrosis stage by histopathological analysis. The lead investigators of each of the six studies were contacted and the data were collected. To meta-analyze vitamin D levels in F0-F2 vs F3-F4 fibrosis, a random-effects meta-analysis fit using restricted maximum likelihood was applied. To examine trends across each stage of fibrosis with respect to vitamin D levels, a meta-regression was performed. P < 0.05 was considered statistically significant. RESULTS A total of 937 subjects from six studies were included in the final analysis to evaluate the association of serum vitamin D levels in patients with NAFLD based on their liver fibrosis stage by histopathological analysis. The lead investigators of each of the six studies were contacted and the data were collected. First, the investigators performed a meta-analysis to compare serum vitamin D levels in patients with NAFLD with stage F0-F2 compared to F3-F4, which did not show significance [meta-estimate of the pooled mean difference =-0.86, P = 0.08(-4.17, 2.46)]. A metaregression evaluation of serum vitamin 25(OH)D levels across the individual stages(F0-F4) of fibrosis did not show an association for the six included studies.CONCLUSION Low vitamin D status is not associated with higher stages of liver fibrosis in patients with NAFLD. | Behnam Saberi Alia S Dadabhai Julie Nanavati Lin Wang Russell T Shinohara Gerard E Mullin | 2018 | World Journal of Hepatology2018，10，1： | 3 |
| 4 | Enhancement of surface wettability via micro-and nanostructures by single point diamond turning显示文摘Studies on surface wettability have received tremendous interest due to their potential applications in research and industrial processes. One of the strategies to tune surface wettability is modifying surface topography at micro-and nanoscales. In this research, periodic micro-and nanostructures were patterned on several polymer surfaces by ultra-precision single point diamond turning to investigate the relationships between surface topographies at the micro-and nanoscales and their surface wettability. This research revealed that single-point diamond turning could be used to enhance the wettability of a variety of polymers, including polyvinyl chloride(PVC), polyethylene 1000(PE1000), polypropylene copolymer(PP) and polytetrafluoroethylene(PFTE), which cannot be processed by conventional semiconductor-based manufacturing processes. Materials exhibiting common wettability properties(θ≈ 90°) changed to exhibit 'superhydrophobic' behavior(θ > 150°). Compared with the size of the structures, the aspect ratio of the void space between micro-and nanostructures has a strong impact on surface wettability. | Nicolás Cabezudo Jining Sun Behnam Andi Fei Ding Ding Wang Wenlong Chang Xichun Luo Ben B.Xu | 2019 | Nanotechnology and Precision Engineering2019，2，1： | 2 |
