RESUMO
BACKGROUND: It has been reported that acute stroke services were compromised during COVID-19 due to various pandemic-related issues. We aimed to investigate these changes by recruiting centers from different countries. METHODS: Eight countries participated in this cross-sectional, observational, retrospective study by providing data from their stroke data base. We compared 1 year before to 1 year during COVID-19 as regards onset to door (OTD), door to needle (DTN), door to groin (DTG), duration of hospital stay, National Institute of Health Stroke Scale (NIHSS) at baseline, 24 h, and at discharge as well as modified Rankin score (mRS) on discharge and at 3 months follow-up. RESULTS: During the pandemic year, there was a reduction in the number of patients, median age was significantly lower, admission NIHSS was higher, hemorrhagic stroke increased, and OTD and DTG showed no difference, while DTN time was longer, rtPA administration was decreased, thrombectomy was more frequent, and hospital stay was shorter. mRS was less favorable on discharge and at 3 months. CONCLUSION: COVID-19 showed variable effects on stroke services. Some were negatively impacted as the number of patients presenting to hospitals, DTN time, and stroke outcome, while others were marginally affected as the type of management.

OBJECTIVES: In this research we wanted to highlight the importance of defining Borderzone infarctions (BZI) as a separate subtype in stroke classifications. We thus studied cases of isolated BZI, small vessel disease (SVD), and large vessel disease (LVD), to identify their points of similarities and difference in a sample of Egyptian patients. METHODS: This is a cross-sectional (observational) study. Consecutive 637 acute ischemic stroke patients were recruited over a 2 year period, from 2 stroke units of Ain Shams University hospitals in Egypt. Medical history and laboratory investigations were done to identify risk factors. National Institute of Health Stroke Scale (NIHSS) was performed on admission, and modified Rankin scale (mRS) on admission, and after 3 months. MRI brain was done to identify stroke subtype; MRA and carotid duplex were used to define vascular status. RESULTS: Among the studied group of patients, 72 (11.3%) had BZI, 145 (22.8%) had SVD, 165 (26%) had LVD, and 255 were excluded as they had either undetermined, or mixed etiology. BZI showed significantly older age, early confluent lesions, more disease severity by NIHSS, and worst outcome by mRS (P < 0.05). SVD had more microbleeds than BZI and LVD. LVD showed lower prevalence of hypertension and lower high-density lipoprotein levels. CONCLUSIONS: Isolated BZI, SVD, and LVD infarctions have characteristic risk factors and clinical patterns. Further studies are needed to identify if they are different from cases with mixed pathology. This could have an impact on the selection of primary and secondary preventive measures appropriate to each type.
