Comparison of surgical treatment results of critical limb ischemia and analysis off actors influencing the outcome of surgical treatment

Objective. To evaluate the results of surgical treatment of critical limb ischemia in two specialized vascular centers. Materials and methods. The results of surgical treatment of 202 patients with critical lower limb ischemia, which were operated in two specialized vascular centers: I Group (76 patients) -ClinicofVascularSurgery at the Military Hospital, Ruzomberok,Slovak Republic; II Group (126 patients) -ClinicofVascularSurgery, EastSlovakInstituteofCardiovascularDiseases, Kosice, Slovak Republic. Results.The patency of arterial reconstructions in I Group was: the femoro-supragenicular segment: 1 year -83%, 3 years - 73%;the infragenicular segment: 1 year - 68%, 3 years - 52%. In II Group -the femoro-supragenicular segment: 1 year - 91%, 3 years - 82%;the infragenicular segment: 1 year - 72%, 3 years - 64%. Conclusion.The patency of arterial reconstructions during the first year in both vascular centers was without statistical difference. The femoro-supragenicular reconstructions had the best patency over three years (> 70%). The following factors influenced the duration of arterial reconstructions: the type of graft used, diabetesmellitus, smoking

SWITCH workbench: A novel approach for the development and deployment of time-critical microservice-based cloud-native applications

Time-critical applications, such as early warning systems or live event broadcasting, present particular challenges. They have hard limits on Quality of Service constraints that must be maintained, despite network fluctuations and varying peaks of load. Consequently, such applications must adapt elastically on-demand, and so must be capable of reconfiguring themselves, along with the underlying cloud infrastructure, to satisfy their constraints. Software engineering tools and methodologies currently do not support such a paradigm. In this paper, we describe a framework that has been designed to meet these objectives, as part of the EU SWITCH project. SWITCH offers a flexible co-programming architecture that provides an abstraction layer and an underlying infrastructure environment, which can help to both specify and support the life cycle of time-critical cloud native applications. We describe the architecture, design and implementation of the SWITCH components and describe how such tools are applied to three time-critical real-world use cases
