The management of stroke in rural and regional areas is variable in both the developed and developing world. Informed by best-practice guidelines and recommendations for systems of stroke care, adaptable models of care that are appropriate for local needs should be devised for rural and regional settings. This review addresses the issue of the provision of appropriate services in rural and regional settings, with particular attention to the barriers involved, according to the classification of Low Human Development Country (LHDC), Medium Human Development Country (MHDC) and High Human Development Country (HHDC). We discuss the need and feasibility of developing implementing stroke care in rural settings according to best-practice recommendations, within models of care adapted to local conditions.

Meta Analysis
Polymorphisms in platelet glycoprotein 1balpha and factor VII and risk of ischemic stroke: a meta-analysis.
Platelets and components of the coagulation cascade are known to be instrumental in the pathogenesis of arterial occlusive disorders. The aim of this meta-analysis is to test the hypothesis that genetic variation in the platelet glycoprotein 1balpha and Factor VII genes influence the occurrence of ischemic stroke. All genetic association studies that examined the R353Q (rs6046) polymorphism of the Factor VII gene and 2 polymorphisms of the platelet glycoprotein (1balpha) gene (Thr/Met rs6065 and Kozak sequence -5 C/T rs2243093) in relation to ischemic stroke were examined. ⋯ This analysis provides strong evidence that the Factor VII R353Q gene polymorphism is not associated with ischemic stroke, that the Thr/Met polymorphism of GP1balpha is associated with ischemic stroke in a dominant genetic model, and that the Kozak sequence polymorphism of GP1balpha may be close to another causative locus that is associated with ischemic stroke.

Multicenter Study
Dual antithrombotic therapy increases severe bleeding events in patients with stroke and cardiovascular disease: a prospective, multicenter, observational study.
We sought to determine the incidence and severity of bleeding events in patients with stroke and cardiovascular diseases who were taking oral antithrombotic agents in Japan, where the incidence of hemorrhagic stroke is higher than in Western countries. ⋯ The incidence of bleeding events during antithrombotic therapy in Japan was similar to that reported for Western countries, although the trials used different study designs. Dual antithrombotic therapy was independently related to an increased risk of bleeding events.

Epidemiological patterns of stroke may change with economic development. It is important to understand these changes for making timely strategies for stroke prevention. The aim of this study was to examine the changes in trends of stroke epidemiology during a period of fast economic development in China, based on data of the Sino-MONICA-Beijing project. ⋯ Characteristics of stroke transition were found during a period of economic development in China. The changes in patterns of stroke have raised new challenges and the need for priority adjustment for stroke prevention in China.

Apoptosis has been implicated as the prominent form of cell death in the brain perihematomal region in animal models and in autopsy or postsurgical human studies. Both the Fas system and caspase activation play a central role in apoptotic pathways. The aims of this study were to investigate soluble Fas (s-Fas) plasma levels after acute intracerebral hemorrhage (ICH), to determine its influence on clinical and radiologic features, and to assess Fas receptor and Fas ligand (Fas-L) protein expression in human ICH brain tissue. ⋯ A decreased plasma s-Fas level together with an increased Fas-L amount in perihematomal brain tissue suggest Fas-mediated apoptosis involvement in this disease.
