Objectives To understand variability in modified Rankin Scale scores from discharge to 90 days acute ischaemic stroke patients following treatment, and examine prediction of 90-day score by using disposition. Materials methods Retrospective analysis treatment was performed January 2016 March 2020. Data collection included demographic clinical characteristics outcomes data (modified at discharge, 30 disposition). Pearson’s χ 2 test assessed statistical differences distribution days. The...

Evidence has shown that endovascular thrombectomy (EVT) treatment improves clinical outcomes. Yet, its benefit remains uncertain in patients with large established infarcts as defined by ASPECTS (Alberta Stroke Program Early CT Score) <6. This study evaluates the cost-effectiveness of EVT, compared standard care (SC), acute ischemic stroke (AIS) 3-5.

In this paper, we consider the unit commitment problem of a power system with high penetration renewable energy. The optimal day-ahead scheduling is formulated as risk-averse stochastic optimization model in which load balance satisfied prescribed probability level. order to handle ambiguous joint distribution generation, feasible set approximated by an quantile-based uncertainty set. Results highlight importance large sample size providing reliable solutions SCUC problems. method flexible...
