Software Defined Networking(SDN)being an emerging network control model is widely recognized as a control and management *** model provides efficient techniques to control and manage the enterprise *** emerging paradigm is edge computing in which data processing is performed at the edges of the network instead of a central *** data processing at the edge nodes reduces the latency and bandwidth *** SDN,the controller is a single point of *** security issues related to the traditional network can be solved by using SDN central management and *** Spoofing and Network Intrusion are the most common *** attacks severely degrade performance and *** propose an edge computing-based mechanism that automatically detects and mitigates those *** this mechanism,an edge system gets the network topology from the controller and the Address Resolution Protocol(ARP)traffic is directed to it for further *** such,the controller is saved from unnecessary processing related to addressing *** propose a graph computation based method to identify the location of an attacker or intruder by implementing a graph difference *** using the correct location information,the exact attacker or intruder is blocked,while the legitimate users get access to the network *** proposed mechanism is evaluated in a Mininet simulator and a POX *** results show that it improves system performance in terms of attack mitigation time,attack detection time,and bandwidth requirements.

Update on management of gastric varices

引用

World Journal of Hepatology 2019年第3期11卷 250-260页

作者： Louisa J Vine mohsan Subhani Juan G Acevedo South West Liver Unit University Hospitals Plymouth NHS Trust

Gastric varices(GV) have different physiology and clinical characteristics compared to oesophageal varices(OV). There is little information about the management of GV. Most part of the recommendations is extrapolated from studies where the majority of participants had OV. Thus, most recommendations lack of strong evidence. This is a comprehensive review on all aspects of management of GV, i.e., primary, secondary prophylaxis and management of acute bleeding. The papers on which international societies' recommendations are based are scrutinised in this review and areas of research are identified.

BACKGROUND Non-alcoholic fatty liver disease(NAFLD)represents a growing public health concern,with patients having higher risk of morbidity and *** has a considerably high prevalence in the general population,estimated 20%-40%in Europe,and is asymptomatic until late in the disease *** is therefore important to identify and validate tools that predict hard outcomes such as mortality for use in clinical practice in risk-stratifying NAFLD *** To evaluate available evidence on the use of non-invasive test(s)as prognostic factors for mortality in *** We performed electronic searches of Medline and EMBASE(Ovid)until 7^(th)January 2021 of studies in NAFLD *** markers included serum biomarkers,non-invasive scoring systems,and non-invasive *** population included all spectrums of disease severity,including NAFLD and non-alcoholic steatohepatitis(NASH).Outcomes included all-cause,and cardiovascular *** non-invasive tests were synthesised in a narrative systematic ***,we conducted a meta-analysis of non-invasive scoring systems for predicting all-cause and cardiovascular mortality,calculating pooled hazard ratios and 95%confidence(STATA 16.1).RESULTS Database searches identified 2850 studies-24 were included.16 studies reported non-invasive scoring systems,10 studies reported individual biomarkers,and 1 study reported imaging modalities.4 studies on non-invasive scoring systems(6324 participants)had data available for inclusion in the *** non-invasive scoring system that performed best at predicting all-cause mortality was NAFLD fibrosis score(NFS)[pHR 3.07(1.62-5.83)],followed by fibrosis-4 index[pHR 3.06(1.54-6.07)],BARD[pHR 2.87(1.27-6.46)],and AST to platelet ratio index[pHR 1.90(1.32-2.73)].NFS was also prognostic of cardiovascular-related mortality[pHR 3.09(1.78-5.34)].CONCLUSION This study reaffirms that non-invasive scoring systems,especially NFS,are reliable prognostic mark
