Extraintestinal manifestations [EIMs] are common in inflammatory bowel disease [IBD]. Data on epidemiology and risk factors of EIMs IBD patients limited. The aim this study was to investigate the prevalence a large cohort Greek identify for their development.The population consisted patients, who were followed eight tertiary hospitals. Demographic clinical characteristics analysed. diagnosis based standard criteria specialist consultation.In total, 1860 (1001 with Crohn's [CD], 859...

BackgroundAngiogenesis is a complex process, involving great number of mediators. It implicated in the pathogenesis numerous diseases, holding critical role inflammatory bowel disease (IBD). The objective this study was to assess serum levels angiogenin, angiopoietin-1, angiopoietin-2, and endostatin IBD patients.

Inflammatory bowel diseases may cause significant disability. However, little is known regarding the life domains where patients encounter most limitations.To assess patients' overall disability and determine restrictions were applied. Secondarily, we sought for possible relationships among disability, quality of (HRQoL), population characteristics.The study lasted two years (2013-2015) included 200 [52% ulcerative colitis (UC)] from a referral centre. Disability was evaluated using 36-item...

Service placement is a key problem in communication networks as it determines how efficiently the user service demands are supported. This has been traditionally approached through formulation and resolution of large optimization problems requiring global knowledge continuous recalculation solution case network changes. Such approaches not suitable for large-scale dynamic environments. In this paper, determining optimal location facility revisited addressed way that both scalable deals...

Background: Epidermal growth factor (EGF) is a multipotent peptide which contributes to epithelial development, inhibition of gastric acid secretion, acceleration wound healing, and promotion angiogenesis. The aim this study evaluate serum EGF concentrations in inflammatory bowel disease (IBD) patients, with regard patients' characteristics.

Service placement has typically been studied through the formulation and solution of a 1-median problem that is known to be complex require global information. As such approaches are clearly not scalable in dynamic large-scale environments, more reasonable approach service for large, ad hoc autonomic environments would migration. Such migration policy recently proposed tree topologies. The focus present paper devise effective policies general topologies with equal weight links. strategy -...

Background and Objectives: Emerging evidence is placing the Mediterranean diet (MD) in spotlight as a potential dietary model that could benefit inflammatory bowel disease (IBD) patients terms of prevention progress disease. The main aim present study to shed some light on relationship between adherence MD degree activity, well quality life with Crohn’s (CD). Materials Methods: An administered questionnaire was used assess record number parameters, including recent medical weight history,...

Background. The rating form of IBD patients' concerns (RFIPC) provides a unique assessment the worries and inflammatory bowel disease (IBD) patients. Our aims were primarily to validate Greek version RFIPC secondarily describe pattern patients'concerns. Methods. After translating RFIPC, questionnaire was given patients at baseline after 12 weeks. questionnaire's measuring properties evaluated based on consensus-based standards for selection health status measurement instruments (COSMIN)...

Edge computing has emerged as the next big thing in distributed computing, by extending cloud paradigm and offering efficient ways to engage with latency-intolerant applications, such Virtual Reality (VR) multiplayer games. In edge service providers can benefit from existing cellular infrastructure deploy services on servers that reside close proximity users. Given limited available budget for resource investment, one fundamental problem manifests is discovery of a prudent allocation...
