Abstract

During the last two decades there have been significant changes in the structure of the banking sector at the European level. Factors such as globalization, integration and development of information technologies had a significant impact on these changes. In terms of the economic integration of Europe and structural changes, there is a need to redefine the regulatory infrastructure, due to inadequate institutional arrangements. The problem topics about reform of banking regulation and establishment of a banking union, as a new level of economic integration of Europe, has been put in the focus of interest during the global financial crisis. For this reason, the paper attempts to give a comprehensive analysis of the reasons and ways to reform regulation of the banking sector. Using a critical review of the implemented reforms of banking regulation at the national and supranational level will be reconsidered their applicability in specific problem situations and suggest measures for further improvement.

Abstract

Insurance market is characterized by growing competition. This has imposed needs relating to the continuous capacity building of insurance companies, the continuous improvement of operating results and the assessment of the effects of insurers’ financial investment. The ultimate goal of these activities is to implement the planned goals and achieve positive business results. It is evident that the financial stability and efficiency of the insurance sector strengthens the confidence of citizens in this type of financial intermediaries. Bearing in mind the importance of the insurance sector for the financial system and economic system growth and development, the research subject is the analysis of the insurance sector efficiency in the Republic of Serbia. The main research objective is to look at the insurance sector efficiency through the performance analysis of nine selected insurance companies in the period 2007-2018, using DEA window analysis. The analysis and systematization of theoretical research findings, along with empirical data interpretation, description and comparison yielded results pointing to very poor performance of the insurance sector as a whole, because in all years of the observed period the relative average efficiency (technical, pure technical and scale efficiency) was below 100%, especially in the period 2015-2018.

Abstract

Elderly patients with end stage kidney disease represent a challenge for surgeons to create a vascular access.

Determine predictive parameters functionality of the arteriovenous fistulas for hemodialysis in the elderly.

The study was organized as a retrospective study at the Center for Dialysis, Clinic for Urology and Nephrology, Clinical Center Kragujevac. The study included patients older than 65 years with arteriovenous fistula thrombosis, in the period of four years, in which there is information on the length of the functioning fistula. The study included 48 patients, mean age 71.3±5.2 years, 29 (60%) men and 19 (40%) women. The data were analyzed according to gender and demographic structure, type of anastomosis, positioning, length of functioning fistulas, and the lumen diameter of the arteries and veins that are used to create a fistula.

The median length of functioning arteriovenous fistula, based on Kaplan-Meier model, is 16 months (95% CI 6.9-25.1). Median functioning for proximaly located fistulas was 24 months (range, 1-259), while median functioning in patient with distally located fistulas was 8 months (range, 1-96). The difference in relation to the positioning of the fistula was statistically significant (p=0.006). In univariate Cox regression model, a statistically significant predictor of the functioning of arteriovenous fistulae is fistula positioning (B=0.700; p=0.022).

The predictive parameter of survival of arteriovenous fistulas in elderly is proximally located fistula.
