Purpose-To estimate the prevalence of elevated blood pressure in adult patients with acute stroke in the United States (U.S.).Methods-Stroke patients were classified by initial systolic blood pressure into four categories using demographic, clinical, and treatment data from the National Hospital Ambulatory Medical Care Survey, the largest study of utilization and provision of emergency department services in the U.S. We also compared the age-, sex-, and ethnicity-adjusted rates of elevated blood pressure strata comparable with stages 1 and 2 hypertension in the U.S. population.Results-Of the 563,704 stroke patients evaluated, initial systolic blood pressure was <140 mm Hg in 173,120 patients (31%), 140-184 mm Hg in 315,207 patients (56%), 185-219 mm Hg in 74,586 patients (13%), and ≥220 mm Hg in 791 patients (0.1%). The mean time interval between presentation and evaluation was 40 ± 55, 33 ± 39, 25 ± 27, and 5 ± 1 minutes for increasing systolic blood pressure strata (p=0.009). A 3-and 8-fold higher rate of elevated blood pressure strata was observed in acute stroke than the existing rates of stages 1 and 2 hypertension in the U.S. population. Labetalol and hydralazine were used in 6,126 (1%) and 2,262 (0.4%) patients, respectively. Thrombolytics were used in 1,283 patients (0.4%), but only in those with SBP of 140-184 mm Hg.Conclusions-In a nationally representative large dataset, elevated blood pressure was observed in over 60% of the patients presenting with stroke to the emergency department. Elevated blood pressure was associated with an earlier evaluation, however, the use of thrombolytics was restricted to ischemic stroke patients with systolic blood pressure <185 mm Hg.

Coronavirus disease 2019 , caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is a global health threat. Some COVID-19 patients have exhibited widespread neurological manifestations including stroke. Acute ischemic stroke, intracerebral hemorrhage, and cerebral venous sinus thrombosis have been reported in patients with COVID-19. COVID-19-associated coagulopathy is increasingly recognized as a result of acute infection and is likely caused by inflammation, including inflammatory cytokine storm. Recent studies suggest that axonal transport of SARS-CoV-2 to the brain can occur via the cribriform plate adjacent to the olfactory bulb that may lead to symptomatic anosmia. The internalization of SARS-CoV-2 is mediated by the binding of the spike glycoprotein of the virus to the angiotensin-converting enzyme 2 (ACE2) on cellular membranes. ACE2 is expressed in several tissues including lung alveolar cells, gastrointestinal tissue, and brain. The aim of this review is to provide insights into the clinical manifestations and pathophysiological mechanisms of stroke in COVID-19 patients. SARS-CoV-2 can down-regulate ACE2 and, in turn, overactivate the classical renin-angiotensin system (RAS) axis and decrease the activation of the alternative RAS pathway in the brain. The consequent imbalance in vasodilation, neuroinflammation, oxidative stress, and thrombotic response may contribute to the pathophysiology of stroke during SARS-CoV-2 infection.

Background and Purpose-The Joint National Committee on High Blood Pressure identified a new category of blood pressure in adults termed prehypertension. Our objective was to determine the long-term risk of cardiovascular diseases associated with this new category in a well-defined cohort of adults. Methods-We evaluated the association of prehypertension (120 to 139/80 to 89 mm Hg) and hypertension (Ͼ140/ 90 mm Hg) with the incidence of atherothrombotic brain infarction (ABI), all strokes, myocardial infarction (MI), and coronary artery disease (CAD) using pooled repeated measures and Cox proportional hazards analyses during follow-up after adjusting for age, gender, obesity, diabetes mellitus, hypercholesterolemia, cigarette smoking, and study period in a cohort of 5181 persons who participated in the Framingham Study. Results-Among the 11 116 person observations with a mean follow-up period of 9.9Ϯ1.0 years, prehypertension was not associated with an increased risk for ABI (relative risk [RR], 2.2; 95% CI, 0.5 to 9.3). Among the 11 802 person observations with a mean follow-up period of 9.7Ϯ1.5 years, prehypertension was associated with an increased risk for MI (RR, 3.5; 95% CI, 1.6 to 7.5). Prehypertension was also associated with an increased risk of CADs among the 11 570 person observations (RR, 1.7; 95% CI, 1.2 to 2.4). Conclusions-Prehypertension appears to be associated with an increased risk of MI and CAD but not stroke. Further studies are required to confirm the anticipated benefits of identifying and intervening in persons with prehypertension.

Background: The interaction between coronavirus disease 2019 (COVID-19) and noncommunicable diseases may increase the global burden of disease. We assessed the association of COVID-19 with ageing and non-communicable diseases. Methods: We extracted data regarding non-communicable disease, particularly cardiovascular disease, deaths, disability-adjusted life years (DALYs), and healthy life expectancy (HALE) from the Global Burden of Disease Study (GBD) 2017. We obtained data of confirmed COVID-19 cases, deaths, and tests from the Our World in Data database as of May 28, 2020. Potential confounders of pandemic outcomes analyzed include institutional lockdown delay, hemispheric geographical location, and number of tourists. We compared all countries according to GBD classification and World Bank income level. We assessed the correlation between independent variables associated with COVID-19 caseload and mortality using Spearman's rank correlation and adjusted mixed model analysis. Findings: High-income had the highest, and the Southeast Asia, East Asia, and Oceania region had the least cases per million population (3050.60 vs. 63.86). Sub-saharan region has reported the lowest number of COVID-19 mortality (1.9). Median delay to lockdown initiation varied from one day From the

Background and Purpose— The purpose of this study was to evaluate the impact of new treatments by examining the changes between 1990 to 1991 and 2000 to 2001 in in-hospital mortality rates and hospital charges in adult patients with stroke. Methods— From the Nationwide Inpatient Survey, the largest all-payer inpatient care database in the United States, patients with stroke admitted in 1990 to 1991 or 2000 to 2001 were studied. We analyzed hospital charges (adjusted for inflation based on the Consumer Price Index of the Bureau of Labor Statistics) and patient outcomes by type of institution: rural, urban nonteaching, and urban teaching in 1990 to 1991 and in 2000 to 2001. Results— In 1990 to 1991, there were 1 736 352 admissions for cerebrovascular diseases, and in 2000 to 2001, there were 1 958 018 admissions. The number of admissions in urban teaching hospitals increased by 13%, 19%, and 25%, for ischemic stroke, intracerebral hemorrhage, and subarachnoid hemorrhage, respectively. The overall in-hospital mortality rate relatively declined by 36% for ischemic stroke, by 6% for intracerebral hemorrhages, and by 10% for subarachnoid hemorrhage. The mean hospital charges increased from $10 500 to $16 200 for patients with ischemic stroke, from $18 300 to $28 800 for patients with intracerebral hemorrhage, and from $37 400 to $65 900 for patients with subarachnoid hemorrhage. Mortality rates among patients admitted after ischemic stroke, intracerebral hemorrhage, and subarachnoid hemorrhage were all lower in urban teaching hospitals than in rural and urban nonteaching hospitals and the mean charges per admission were all higher. Conclusions— There has been an increase in the inflation-adjusted hospital charges for all patients with stroke and a reduction in mortality rates for all stroke subtypes probably related to an increase in the proportion of patients with stroke admitted to urban teaching hospitals.

Purpose of Review The present review discusses the peripheral nervous system (PNS) manifestations associated with coronavirus disease 2019 (COVID-19). Recent Findings Nerve pain and skeletal muscle injury, Guillain-Barré syndrome, cranial polyneuritis, neuromuscular junction disorders, neuro-ophthalmological disorders, neurosensory hearing loss, and dysautonomia have been reported as PNS manifestations in patients with COVID-19. Summary Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes COVID-19. COVID-19 has shown syndromic complexity. Not only does SARS-CoV-2 affect the central nervous system but also it involves the PNS. The PNS involvement may be due to dysregulation of the immune system attributable to COVID-19. Here we review the broad spectrum of PNS involvement of COVID-19.

Intracranial aneurysms are present in roughly 5% of the population, yet most are often asymptomatic and never detected. Development of an aneurysm typically occurs during adulthood, while formation and growth are associated with risk factors such as age, hypertension, pre-existing familial conditions, and smoking. Subarachnoid hemorrhage, the most common presentation due to aneurysm rupture, represents a serious medical condition often leading to severe neurological deficit or death. Recent technological advances in imaging modalities, along with increased understanding of natural history and prevalence of aneurysms, have increased detection of asymptomatic unruptured intracranial aneurysms (UIA). Studies reporting on the risk of rupture and outcomes have provided much insight, but the debate remains of how and when unruptured aneurysms should be managed. Treatment methods include two major intervention options: clipping of the aneurysm and endovascular methods such as coiling, stent-assisted coiling, and flow diversion stents. The studies reviewed here support the generalized notion that endovascular treatment of UIA provides a safe and effective alternative to surgical treatment. The risks associated with endovascular repair are lower and incur shorter hospital stays for appropriately selected patients. The endovascular treatment option should be considered based on factors such as aneurysm size, location, patient medical history, and operator experience.

Purpose of Review Coronavirus disease 2019 (COVID-19) has become a global health crisis of our time. The disease arises from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that binds to angiotensin-converting enzyme 2 (ACE2) receptors on host cells for its internalization. COVID-19 has a wide range of respiratory symptoms from mild to severe and affects several other organs, increasing the complexity of the treatment. There is accumulating evidence to suggest that SARS-CoV-2 can target the nervous system. In this review, we provide an account of the COVID-19 central nervous system (CNS) manifestations. Recent Findings A broad spectrum of the CNS manifestations including headache, impaired consciousness, delirium, loss of smell and taste, encephalitis, seizures, strokes, myelitis, acute disseminated encephalomyelitis, neurogenic respiratory failure, encephalopathy, silent hypoxemia, generalized myoclonus, neuroleptic malignant syndrome and Kawasaki syndrome has been reported in patients with COVID-19. Summary CNS manifestations associated with COVID-19 should be considered in clinical practice. There is a need for modification of current protocols and standing orders to provide better care for COVID-19 patients presenting with neurological symptoms.
