Stroke is the second most common cause of global death following coronary artery disease. Time is crucial in managing stroke to reduce the rapidly progressing insult of the ischemic penumbra and the serious neurologic deficits that might follow it. Strokes are mainly either hemorrhagic or ischemic, with ischemic being the most common of all types of strokes. Thrombolytic therapy with recombinant tissue plasminogen activator and endovascular thrombectomy are the main types of management of acute ischemic stroke (AIS). In addition, there is a vital need for neuroprotection in the setting of AIS. Neuroprotective agents are important to investigate as they may reduce mortality, lessen disability, and improve quality of life after AIS. In our review, we will discuss the main types of management and the different modalities of neuroprotection, their mechanisms of action, and evidence of their effectiveness after ischemic stroke.

Summary SARS Coronavirus‐2 is one of the most widespread viruses globally during the 21st century, whose severity and ability to cause severe pneumonia and death vary. We performed a comprehensive systematic review of all studies that met our standardised criteria and then extracted data on the age, symptoms, and different treatments of Covid‐19 patients and the prognosis of this disease during follow‐up. Cases in this study were divided according to severity and death status and meta‐analysed separately using raw mean and single proportion methods. We included 171 complete studies including 62,909 confirmed cases of Covid‐19, of which 148 studies were meta‐analysed. Symptoms clearly emerged in an escalating manner from mild‐moderate symptoms, pneumonia, severe‐critical to the group of non‐survivors. Hypertension (Pooled proportion (PP): 0.48 [95% Confident interval (CI): 0.35–0.61]), diabetes (PP: 0.23 [95% CI: 0.16–0.33]) and smoking (PP: 0.12 [95% CI: 0.03–0.38]) were highest regarding pre‐infection comorbidities in the non‐survivor group. While acute respiratory distress syndrome (PP: 0.49 [95% CI: 0.29–0.78]), (PP: 0.63 [95% CI: 0.34–0.97]) remained one of the most common complications in the severe and death group respectively. Bilateral ground‐glass opacification (PP: 0.68 [95% CI: 0.59–0.75]) was the most visible radiological image. The mortality rates estimated (PP: 0.11 [95% CI: 0.06–0.19]), (PP: 0.03 [95% CI: 0.01–0.05]), and (PP: 0.01 [95% CI: 0–0.3]) in severe‐critical, pneumonia and mild‐moderate groups respectively. This study can serve as a high evidence guideline for different clinical presentations of Covid‐19, graded from mild to severe, and for special forms like pneumonia and death groups.

Background: Stroke has been linked to a lack of physical activity; however, the extent of the association between inactive lifestyles and stroke risk has yet to be characterized across large populations. Purpose: This study aimed to explore the association between activity-related behaviors and stroke incidence. Methods: Data from 1999 to 2018 waves of the concurrent cross-sectional National Health and Nutrition Examination Survey (NHANES) were extracted. We analyzed participants characteristics and outcomes for all participants with data on whether they had a stroke or not and assessed how different forms of physical activity affect the incidence of disease. Results: Of the 102,578 individuals included, 3851 had a history of stroke. A range of activity-related behaviors was protective against stroke, including engaging in moderate-intensity work over the last 30 days (OR = 0.8, 95% CI = 0.7-0.9; P = 0.001) and vigorousintensity work activities over the last 30 days (OR = 0.6, 95% CI = 0.5-0.8; P < 0.001), and muscle-strengthening exercises (OR = 0.6, 95% CI = 0.5-0.8; P < 0.001). Conversely, more than 4 h of daily TV, video, or computer use was positively associated with the likelihood of stroke (OR = 11.7, 95% CI = 2.1-219.2; P = 0.022). Conclusion: Different types, frequencies, and intensities of physical activity were associated with reduced stroke incidence, implying that there is an option for everyone. Daily or every other day activities are more critical in reducing stroke than reducing sedentary behavior duration.
