The FIB-4 index is a simple and noninvasive algorithm consisting to evaluate liver fibrosis in chronic HCV infection. Aim: To evaluate the utility of FIB-4 index as a noninvasive marker to assess liver fibrosis in chronic HCV infection in comparison to transient elastography. Patients and Methods: We studied 30 patients having chronic HCV infection based on clinical features, laboratory tests, diagnostics images, Fibroscan and FIB-4 score. According to the results of Fibroscan, the 30 patients were classified into two groups in order to obtain a cutoff value to exclude patient with significant fibrosis: group Ia: 7 patients with no or mild liver fibrosis (F0-F1) and group Ib: 23 pa-tients with significant fibrosis or cirrhosis (F2-F3-F4). Group IIa: 17 patients with no or significant fibrosis (F0-F1-F2-F3) and group IIb (F4): 13 patients with cirrhosis (F4). Results: The mean of FIB-4 index increased with the increase of the fibrosis score. FIB-4 index proved to be sensitive and specific in differentiation between patients with no or mild fibrosis (F0-F1) and patients with significant fibrosis or cirrhosis (F2-F3-F4) with the best cutoff value at 1.61. It also proved to be sensitive and specific in differentiation between patients with no or significant fibrosis (F0-F1-F2-F3) and patients with cirrhosis (F4) with cutoff value at 1.88. Conclusion: The FIB-4 index enabled the correct identification of extreme types of fibrosis. Using these cutoffs (1.61 - 1.88), 87% of patients fell outside these ranges and could thus avoid liverbiopsy with an overall accuracy of 70%.

Does Immigration Promote the Investment of the Monopolistic Firm?

In the present paper, we examine the effect of increasing uncertainty of immigrants’ growth on the optimal timing of investment of a firm that has a monopolistic power over the labor market. It is revealed that when the uncertainty of immigrants’ growth is more than a threshold level, increasing uncertainty of immigrants’ growth accelerates the optimal timing of firms’ investment and enhances the economic growth, even if the uncertainty of immigrants’ growth is formulated by the geometric Brownian motion, which is in sharp contrast to the standard result that an increase in the uncertainty postpones the optimal timing. With an increase in the immigrants over the past ten years, workforces in the host countries have been growing significantly to the extent that the immigrants represent 70% of the increase in the workforce in Europe, and 47% in the United States as OECD indicates. In the present paper, we attempted to investigate the effect of increased uncertainty caused by the growi...

Education Policy Implementation: A Mechanism for Enhancing Primary Education Development in Zanzibar

Education is one of the fundamental rights of individuals; therefore, the government of a country needs to develop and strengthen educational policy and quality as well as to ensure that everyone has equal access to basic education. The improvement of access and quality of education in the world is becoming as an essential factor in development, whereas the basic education (primary school), is acknowledged as a foundation of the higher educational development for every country. To fulfill this goal, governments introduce several policies and procedures; however, it requires some reforms and participation from the politician, policymakers, and other stakeholders to re-examine educational policy so that it can lead to multiplication and betterment of the reforms. Educational reforms actually focus on accountability. A positive educational development and reform is very challenging and needs more effort and strategy on how to use and utilize the resources effectively as such it can achie...
