    <jats:sec><jats:title>Background:</jats:title><jats:p> Stroke is a major global cause of death and disability. Most strokes occur in populations of low-middle-income country (LMIC); therefore, the subsequent disease burden is greater than in populations of high-income countries. Few epidemiological data exist for stroke in Latin America, composed primarily of LMIC. </jats:p></jats:sec><jats:sec><jats:title>Aims:</jats:title><jats:p> To determine epidemiological measures of incidence, prevalence, and 1-month case-fatality for stroke in Latin America/Caribbean (LAC) during 1997–2021. </jats:p></jats:sec><jats:sec><jats:title>Summary of review:</jats:title><jats:p> A structured search was conducted to identify relevant references from MEDLINE, WOS, and LILACS databases for prospective observational and cross-sectional studies in LAC populations from January 1997 to December 2021. A total of 9242 records were screened and 12 selected for analysis, seven incidence studies and five prevalence studies. Case-fatality was reported in six articles. Sub-group analysis by age, sex, and income countries was performed. A narrative synthesis of the findings was performed. Meta-analysis was performed using random-effect model to obtain pooled estimates with 95% confidence intervals (CIs). Studies quality was assessed according to the risk of bias criteria described in the Joanna Briggs Institute’s guide. The overall crude annual incidence rate of first-ever stroke in LAC was 119.0 (95% CI = 95.9–142.1)/100,000 people (with high heterogeneity between studies ( I<jats:sup>2</jats:sup> = 98.1%)). The overall crude prevalence was 3060 (95% CI: 95.9–142.1)/100,000 people (with high heterogeneity between studies ( I<jats:sup>2</jats:sup> = 98.8%)). The overall case-fatality at 1 month after the first stroke was 21.1% (95% CI = 18.6–23.7) ( I<jats:sup>2</jats:sup> = 49.40%). </jats:p></jats:sec><jats:sec><jats:title>Conclusion:</jats:title><jats:p> This review contributes to our understanding regarding the burden caused by stroke in LAC. More studies with comparable designs are needed to generate reliable data and should include both standardized criteria, such as the World Health Organization clinical criteria and updated standard methods of case assurance, data collection, and reporting. </jats:p></jats:sec>

    <jats:sec> <jats:title>Background and Purpose—</jats:title> <jats:p>Infratentorial intracerebral hemorrhage (ICH) has a poor outcome but is rarely analyzed by cerebellar versus brain stem location. We evaluated this relationship and clinical outcomes among participants of the INTERACT 1 and 2 (Intensive Blood Pressure Reduction in Acute Cerebral Hemorrhage Trials).</jats:p> </jats:sec> <jats:sec> <jats:title>Methods—</jats:title> <jats:p>Participants with brain stem and cerebellar ICH were compared. Logistic regression models were used to compare outcomes of death or major disability and quality of life.</jats:p> </jats:sec> <jats:sec> <jats:title>Results—</jats:title> <jats:p>Of 195 included patients, 92 (47%) and 103 (53%) had brain stem and cerebellar ICH, respectively. Patients with brain stem ICH were younger (mean [SD] age, 59±13 versus 70±11 years), less female (28.3% versus 50.5%), with higher admission National Institutes of Health Stroke Scale scores (median [interquartile range], 6 [4–10) versus 3 [2–8]), less prior ICH (3% versus 17%), smaller ICH volumes (1.6 mL [1.0–2.8 mL] versus 5.1 mL [2.6–10.7 mL]), and less intraventricular extension (3% versus 39%) than those with cerebellar ICH. Brain stem ICH had higher mortality (odds ratio, 37.1; 95% CI, 1.99–692.27) and worse scores in the European Quality of Life Scale (EQ-5D) pain domain (odds ratio, 3.36; 95% CI, 1.38–8.20).</jats:p> </jats:sec> <jats:sec> <jats:title>Conclusions—</jats:title> <jats:p>Cerebellar and brain stem ICH differ in their clinical characteristics and prognosis, with the latter being associated with higher case fatality and worse EQ-5D scores in the pain domain.</jats:p> </jats:sec> <jats:sec> <jats:title>Clinical Trial Registration—</jats:title> <jats:p> URL: <jats:ext-link xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="uri" xlink:href="https://www.clinicaltrials.gov">https://www.clinicaltrials.gov</jats:ext-link> .
