A Review Of Risk Concepts And Models For Predicting The Risk Of Primary Stroke, Elizabeth Hunter, John D. Kelleher

Articles

Predicting an individual's risk of primary stroke is an important tool that can help to lower the burden of stroke for both the individual and society. There are a number of risk models and risk scores in existence but no review or classification designed to help the reader better understand how models differ and the reasoning behind these differences. In this paper we review the existing literature on primary stroke risk prediction models. From our literature review we identify key similarities and differences in the existing models. We find that models can differ in a number of ways, including the …

Evaluating The Relationship And Outcomes Of Ischemic Stroke In Patients With Covid-19 While Also Reviewing Overall Incidence And Mortality Of Stroke In Vulnerable Populations In The Us, Jaime Dougherty

Rowan-Virtua Research Day

COVID-19 has affected the worldwide population since early 2020 and has remained a health issue. Among the various symptoms and outcomes people are encountering when infected with COVID-19, this virus has also been connected to severe vascular insults involving large vessel occlusions.

Current stroke statistics indicate a nearly twice as high risk of stroke in African Americans when compared to whites. This brings into question how social determinants of health are affecting COVID-19 and stroke incidence.

The purpose of this review is to investigate the relationship between COVID-19 and ischemic stroke while advocating for a more robust primary prevention approach …

Sex Disparities In Access To Acute Stroke Care: Can Telemedicine Mitigate This Effect?, Catherine Wolff, Amelia K. Boehme, Karen Albright, Tzu-Ching Wu, Michael Mullen, Sean Savitz, Charles Branas, James Grotta, Brendan Carr

Journal of Health Disparities Research and Practice

Background: Women have more frequent and severe ischemic strokes than men, and are less likely to receive treatment for acute stroke. Primary stroke centers (PSCs) have been shown to utilize treatment more frequently. Further, as telemedicine (TM) has expanded access to acute stroke care we sought to investigate the association between PSC, TM and access to acute stroke care in the state of Texas.

Methods: Texas hospitals and resources were identified from the 2009 American Hospital Association Annual Survey. Hospitals were categorized as: (1) stand-alone PSCs not using telemedicine for acute stroke care, (2) PSCs using telemedicine for acute stroke …

The Disability Burden Associated With Stroke Emerges Before Stroke Onset And Differentially Affects Blacks: Results From The Health And Retirement Study Cohort, Benjamin D. Capistrant, Nicte I. Mejia, Sze Yan Liu, Qianyi Wang, M. Maria Glymour

Department of Public Health Scholarship and Creative Works

Background.

Few longitudinal studies compare changes in instrumental activities of daily living (IADLs) among stroke-free adults to prospectively document IADL changes among adults who experience a stroke. We contrast annual declines in IADL independence for older individuals who remain stroke-free to those for individuals who experienced a stroke. We also assess whether these patterns differ by sex, race, or Southern birthplace. Methods.

Health and Retirement Study participants who were stroke-free in 1998 (n = 17,741) were followed through 2010 (average follow-up = 8.9 years) for self- or proxy-reported stroke. We used logistic regressions to compare annual changes in odds of …

A Reappraisal Of Stroke Mortality Trends In Brazil (1979 To 2009), Paulo A. Lotufo

Paulo A Lotufo

Background: Brazil has the highest cerebrovascular death rate in the Western Hemisphere. We investigated temporal trends according to gender and stroke subtypes. Methods: We analysed mortality rates between 1979 and 2009 for different stroke subtypes. Data were stratified by sex and age (35–74 y). The annual percent change (APC) and significant changes in the trends were identified with joinpoint Poisson regression. The average annual percent change (AAPC) for 2005-09 was presented because that period had the best quality of information. Results: After excluding deaths due to stroke sequels, for men, the APCs (95% confidence intervals) were: 1979-84: 0.7 (-0.8 to …

Cardiovascular And Cancer Mortality In Brazil, Paulo A. Lotufo

Paulo A Lotufo

Cancer are not surpassing Cardiovascular Diseases. Here you have an evaluation of mortality in Brazil. The debate was ignited by paper from IARC (International Agency for Research on Cancer) that forecasts cancer deaths surpassing heart diseases rates during de 2020’s. There is no dispute about the fact that - at least in the US and other countries - the decline of mortality deaths for heart diseases presenting a faster pace compared to cancer death rates. It is an epidemiological evidence that must be analyzed and some headline fueling hype as “heart diseases as an old agenda of public health and …

Stroke mortality rates have a discrepant distribution according to socioeconomic variables as social exclusion in Brazil. Recently, data from race has been available from the official health statistics considering five categories: White, Mixed, Black, Asian and Native. We addressed in the city of São Paulo, Brazil, an analysis of cerebrovascular mortality according to race (excluding Asian and Native due to small number of events) and gender during 1999-2001 for people aged 30 to 79 years-old. For all cerebrovascular diseases, age-adjusted mortality rates (x 100,000) for men were higher for Black (150.2), intermediate for Mixed (124.2) and lower for White (104.5) …

Higher Burden Of Hemorrhagic Stroke Among Women An Autopsy-Based Study In São Paulo, Brazil, Paulo A. Lotufo

Paulo A Lotufo

The aim of this study was to verify the gender difference in sudden cardiovascular death, mainly comparing brain infarction and hemorrhagic stroke. We analyzed 970 autopsy cases from a total of 3,802 nonviolent deaths (448 considered as sudden deaths, 296 undetermined, and 226 non-sudden deaths) including patients aged 30–69 years. All cardiovascular diseases were responsible for 69% of sudden deaths, and all types of stroke for only 14%. The proportions of sudden death for all cardiovascular diseases, coronary heart disease and ischemic stroke deaths were similar for both sexes. However, sudden deaths due to all types of stroke (women 20.0%; …

Stroke In Brazil: A Neglected Disease, Paulo A. Lotufo

Paulo A Lotufo

The turning point in the transition from infectious diseases to non-transmittable diseases in Brazil occurred in the 1960s, taking the country as a whole. However, considering the main cities, such as São Paulo and Rio de Janeiro, cerebrovascular disease mortality rates have surpassed the “old cardiovascular diseases” like rheumatic heart disease and syphilitic aortic disease since the end of World War II. Until the end of the 1980s, the burden of stroke mortality observed in the main Brazilian cities was higher than in the United States, Canada and western European countries, and similar to what is observed in Eastern Europe …
