Stroke in women: experience in a developing country.

BACKGROUND: Several studies have addressed gender differences in stroke. Yet, results are diverse, and research is still required in different populations. So, this study investigates variation in stroke according to gender in a developing country. METHODS: This is a registry-based, retrospective observational cross-sectional study comparing men and women as regards age, risk factors, stroke severity, quality of services, and stroke outcome. RESULTS: Data analyzed comprised 4620 patients. It was found that men outnumbered women, while women had an older age, more prevalence of hypertension and atrial fibrillation, with severer strokes and worse outcomes. However, there was no gender difference in promptness nor frequency of administration of revascularization therapies. CONCLUSION: Despite the gender difference in risk factors and stroke severity, we could not detect any significant disparity in acute stroke services provided to either gender. Among age categories in women, we identified differences in acute ischemic stroke subtypes, and acute management in favor of older age.

Urban Versus Rural Egypt: Stroke Risk Factors and Clinical Profile: Cross-Sectional Observational Study.

BACKGROUND: Egypt is a densely populated country with living habits and health care services that differ from urban to rural regions. We aimed to study how characteristics of stroke vary among these regions. METHODS: This is a cross-sectional observational study of ischemic stroke, thus hemorrhagic and venous strokes were excluded. A total of 1475 ischemic stroke patients were recruited for analysis from a tertiary hospital in Cairo representing urban area and from a secondary care hospital in Suhag representing rural region. RESULTS: Analysis was done for 1143 ischemic stroke patients from urban and 332 from rural area. Onset to door was shorter in urban. Urban patients showed an older age and higher prevalence of hypertension and diabetes (65.9%, 48.6% respectively), while rural patients were characterized by female preponderance (51.5%), more dyslipidemia, smoking 44.6%, stroke in young 20.5%, atrial fibrillation 23.8% % and recurrent stroke 44.3%. Rural cases showed a severer deficit at onset and poorer outcome. CONCLUSION: Vascular risk factors, stroke type, and presentation tend to differ in Egypt according to the geographic distribution whether urban or rural. Studying patterns of such difference may aid in planning specific targeted preventive and therapeutic strategies for stroke in urban and rural Egypt.

Stroke burden in Egypt: data from five epidemiological studies.

PURPOSE: Accurate data on the epidemiology of stroke in Egypt is scarce. The aim of this review is to address this issue based on available community-based studies and compare the resulting findings to those of other regional and international studies. METHOD: A systematic literature search was conducted to identify population-based epidemiological studies of stroke in Egyptians. Original articles published in English between 1990 and 2016 were included. Five studies from five different governorates in southern Egypt fulfilled the study criteria (Qena, Sohag, Assiut, New Valley and Red Sea). RESULTS: The mean and median crude prevalence rates (CPRs) across the five studies, which were conducted in southern Egypt were 721.6/100,000 and 655/100,000, respectively. The mean and median crude incidence rates (CIRs) were 187/100,000 and 180.5/100,000, respectively. The average CPR weighted by sample population size was 613/100,000 and the average CIR weighted by sample population size was 202/100,000. CONCLUSION: The incidence and prevalence of stroke in Egypt are high. More population-based studies are urgently needed in northern Egypt and in Cairo - the capital of Egypt.

Characteristics, causes and impact of headache among a sample of physicians working during COVID-19 pandemic.

Background: Headache is considered a common health problem affecting physicians during Coronavirus disease-19 (COVID-19) pandemic and has direct impact on their productivity. Wearing personal protective equipment (PPE), stress and lack of sleep are common factors affecting their headache. Results: Out of 165 participants, 38(23%) experienced new onset headache. Participants using Combined Face and eye PPE usage were at higher risk of developing headache compared to single PPE users, Participants wearing face shield were at higher risk of developing headache compared to eyewear non users. Conclusion: COVID-19 hospital's physicians may experience new-onset headache or change in their previously existing headache, mostly disposed by PPE eyewear and combined face and eye PPE.

Guillain-Barré syndrome following different COVID-19 vaccines: a case series.

Background: The COVID-19 vaccine-related Guillain-Barré syndrome (GBS) has been described for both messenger-RNA vaccine and adenovirus-vectored types in a few cases with great public concern and the necessity to inform physicians about the variations of its presentations given its life-threatening consequences. Case presentation: This case series highlighted the presentation with GBS following different COVID-19 vaccinations in seven cases with ages ranging from 29 to 59 years. Three patients received the AstraZeneca vaccine, two received the Pfizer vaccine, one received Sinopharm, and one received the Janssen vaccine. Latency ranged from 5 to 60 days and cases achieved either partial or complete improvement after treatment trials. Patients responded to plasmaphereses, but not pulse steroid therapy. Conclusion: This case series highlights the variable presentations and outcomes of GBS following different COVID-19 vaccination from one center. The early identification and appropriate management of such cases can lead to better outcomes.

Door to Needle Count Down: A 3-Years Experience in an Egyptian University Stroke Center.

BACKGROUND: The purpose of this study is to share our experience in changing hospital strategies to achieve rapid thrombolysis in acute ischemic stroke (AIS) patients in 2 university stroke centers. Rapid reperfusion by shortening door to needle time (DTN) reduces morbidity and mortality for patients with AIS. Our aim is to evaluate the effect of applying certain logistic strategies to reduce DTN for thrombolysis and its impact on clinical outcome. METHODS: In this retrospective registry-based observational study from the SITS-ISTR Dataset, we studied AIS patients admitted to 2 stroke centers in Ain Shams University over 3 successive years from 2016 till 2018. We analyzed change of DTN and outcome at 3 months by modified Rankin scale over these 3 years. RESULTS: By the end of the 3 year period there was a 6.1% increase in number of patients receiving thrombolysis. There was a significant decrease of median DTN by 41%, and increase in percentage of patients receiving recombinant tissue plasminogen activator within a shorter DTN. Also, the number of patients with a favorable outcome (modified Rankin scale≤2) increased by 23.3%. There was insignificant difference regarding mortality rate. CONCLUSION: Applying a goal-directed corrective strategy to improve quality of service can, in a short time, reduce DTN and improve patient outcome.

Factors related to time of stroke onset versus time of hospital arrival: A SITS registry-based study in an Egyptian stroke center.

BACKGROUND: High-quality data on time of stroke onset and time of hospital arrival is required for proper evaluation of points of delay that might hinder access to medical care after the onset of stroke symptoms. PURPOSE: Based on (SITS Dataset) in Egyptian stroke patients, we aimed to explore factors related to time of onset versus time of hospital arrival for acute ischemic stroke (AIS). MATERIAL AND METHODS: We included 1,450 AIS patients from two stroke centers of Ain Shams University, Cairo, Egypt. We divided the day to four quarters and evaluated relationship between different factors and time of stroke onset and time of hospital arrival. The factors included: age, sex, duration from stroke onset to hospital arrival, type of management, type of stroke (TOAST classification), National Institute of Health Stroke Scale (NIHSS) on admission and favorable outcome modified Rankin Scale (mRS ≤2). RESULTS: Pre-hospital: highest stroke incidence was in the first and fourth quarters. There was no significant difference in the mean age, sex, type of stroke in relation to time of onset. NIHSS was significantly less in onset in third quarter of the day. Percentage of patients who received thrombolytic therapy was higher with onset in the first 2 quarters of the day (p = <0.001). In-hospital: there was no difference in percentage of patients who received thrombolytic therapy nor in outcome across 4 quarters of arrival to hospital. CONCLUSION: Pre-hospital factors still need adjustment to improve percentage of thrombolysis, while in-hospital factors showed consistent performance.

Arabic cross cultural adaptation and validation of the National Institutes of Health Stroke Scale.

INTRODUCTION: The National Institutes of Health Stroke Scale (NIHSS), the most commonly used tool to quantify neurological deficit in acute stroke, was initially developed in English. We present our experience in developing and validating an Arabic version of the NIHSS (arNIHSS). RESULTS: In 6months, 137 patients were recruited (mean age±standard deviation 62±12years; 48 women). For interrater agreement, weighted kappa value ranged from 0.36 to 0.66 and intraclass correlation coefficient (ICC) for the whole scale was excellent at 0.95 (95% confidence interval [CI] 0.94-0.97). For intrarater agreement, weighted kappa ranged from 0.52 to 1.0 and the ICC was 0.94 (95% CI 0.87-0.98). The construct validity of the arNIHSS is demonstrated by its correlation with the DWI-ASPECT and the 3months mRS score (Spearman correlation -0.46 and 0.58 respectively; P<0.001 for both). CONCLUSION: We developed and validated a culturally adapted Arabic version of the NIHSS. Further validation in other Arab countries is recommended.
