Background and purposeSpain has been heavily affected by COVID-19. Reallocation of resources for managing the outbreak might have caused a disruption in stroke care. This study analyses the impact on stroke care of reorganising the healthcare system in response to the first COVID-19 outbreak peak in Spain and the strategies adopted by Spanish stroke units to deal with this impact.Materials and methodsWe obtained data from a structured survey sent to the responsible of stroke units across the country. We recorded the number of strokes, stroke code activations, intravenous thrombolysis treatments and mechanical thrombectomies during February and March 2019 and 2020. We also collected information on the impact on workflow metrics and on the availability of specialised neurological care and rehabilitation treatments, the characteristics of stroke care for patients with SARS-CoV-2 infection and the impact on human resources. We compared the activity data between 2019 and 2020 and the information on activity and impact on stroke care between regions classified according to the disease incidence rate.ResultsFifty-seven (75%) of all stroke units in Spain responded to the survey. There was an overall reduction in admissions for all stroke types during the outbreak’s peak and in the number of stroke code activations and intravenous thrombolysis treatments, results that were independent of the COVID-19 incidence rate. Participants reported a delay in workflow metrics and a reduction of admissions to stroke units, outpatient clinics and rehabilitation therapies. Specific pathways and protocols for managing stroke patients with SARS-CoV-2 infection have been established.ConclusionThe COVID-19 outbreak has jeopardised all phases of stroke care. As a consequence, some patients with stroke did not receive adequate treatment.

The syndrome of headache and neurologic deficits with CSF lymphocytosis (HaNDL) is a self-limited, benign entity, characterized by one or more episodes of severe headache, transient neurologic deficits and lymphocytic pleocytosis in CSF [1]. Functional imaging studies have shown changes in blood flow and brain activity whose temporal and spatial characteristics are similar to those of CSD, mechanism similar to that proposed for migraine with aura [2,3,4]. Recently, was described the clinical utility of a prominent vein named index vein, found on SWI during migraine aura that drains the cortical area responsible for patient´s symptoms [5,6]. Our paper reports a patient with HaNDL and index vein, adding further evidence for spreading depression-like mechanism, similar to that proposed for migraine.

Background and Objective: Oral anticoagulation (OAC) for secondary stroke prevention is recommended in atrial fibrillation (AF) and other sources of cardioembolic stroke. Our objectives were to explore the differences in ischemic and hemorrhagic events when using OAC for secondary stroke prevention according to the type of anticoagulant treatment and to analyze the number and reasons for OAC switches during long-term follow-up. Methods: Ischemic stroke (IS) patients who were discharged on OAC for secondary stroke prevention from January 2014 to October 2017 were recruited in a prospective, multicenter, hospital-based registry. Follow-up at 3 months was scheduled at the outpatient clinic with subsequent annual phone interviews for 3 years. Patients were classified into three study groups according to OAC at discharge: Vitamin K antagonist (VKA), Factor Xa inhibitor (FXa), or direct thrombin inhibitor (DTI). We compared stroke recurrences, intracranial hemorrhage, major bleeding, and all-cause mortality during the follow-up. We recorded any switches in OAC and the main reasons for the change. Results: A total of 241 patients were included. An anticoagulant was indicated in the presence of a source of cardioembolic stroke in 240 patients (99.6%) and lupus plus antiphospholipid syndrome in one patient. Up to 86 patients (35.6%) were on OAC before the index stroke; in 71 (82.5%) of them, this was VKA. At hospital discharge, 105 were treated with FXa (43.8%), 96 with VKA (39.6%), and 40 with DTI (16.6%). The cumulative incidences at 3 years were 17% for stroke recurrence, 1.6% for intracranial hemorrhage, 4.9% for major hemorrhage, and 22.8% for all-cause mortality, with no differences among the OAC groups in any outcomes. During the follow-up, 40 OAC switches were recorded (63% of them to FXa), mostly due to stroke recurrence. Conclusion: Long-term OAC in secondary stroke prevention is associated with a lower frequency of bleeding complications than stroke recurrences. No differences between anticoagulant drugs were found in any of the analyzed outcomes. The main cause for OAC switch during follow-up was stroke recurrence., This study was supported by grants from the Foundation for Biomedical Research of La Paz University Hospital (PI 1131)
