    <jats:title>Abstract</jats:title><jats:sec> <jats:title>Background</jats:title> <jats:p>Early intensive blood pressure (BP) lowering remains the most promising treatment for acute intracerebral hemorrhage (ICH), despite discordant results between clinical trials and potential variation in the treatment effects by approach to control BP. As the third in a series of clinical trials on this topic, the INTEnsive care bundle with blood pressure Reduction in Acute Cerebral hemorrhage Trial (INTERACT3) aims to determine the effectiveness of a goal-directed care bundle protocol of early physiological control (intensive BP lowering, glycemic control, and pyrexia treatment) and reversal of anticoagulation, in acute ICH.</jats:p> </jats:sec><jats:sec> <jats:title>Methods</jats:title> <jats:p>INTERACT3 is a pragmatic, international, multicenter, stepped-wedge (4 phases/3 steps), cluster-randomized controlled trial to determine the effectiveness of a multifaceted care package in adult (age ≥ 18 years) patients (target 8360) with acute ICH (&lt; 6 h of onset) recruited from 110 hospitals (average of 19 consecutive patients per phase) in low- and middle-income countries. After a control phase, each hospital implements the intervention (intensive BP lowering, target systolic &lt; 140 mmHg; glucose control, target 6.1–7.8 mmol/L and 7.8–10.0 mmol/L in those without and with diabetes mellitus, respectively; anti-pyrexia treatment to target body temperature ≤ 37.5 °C; and reversal of anticoagulation, target international normalized ratio &lt; 1.5 within 1 h). Information will be obtained on demographic and baseline clinical characteristics, in-hospital management, and 7-day outcomes. Central trained blinded assessors will conduct telephone interviews to assess physical function and health-related quality of life at 6 months. The primary outcome is the modified Rankin scale (mRS) at 6 months analyzed using ordinal logistic regression. The sample size of 8360 subjects provides 90% power (<jats:italic>α</jats:italic> = 0.05) to detect a 5.6% absolute improvement (shift) in the primary outcome of the intervention versus control standard care, with various assumptions.</jats:p> </jats:sec><jats:sec> <jats:title>Discussion</jats:title> <jats:p>As the largest clinical trial in acute ICH, INTERACT3 is on schedule to provide an assessment of the effectiveness of a widely applicable goal-directed care bundle for a serious condition in which a clearly proven treatment has yet to be established.</jats:p> </jats:sec><jats:sec> <jats:title>Trial registration</jats:title> <jats:p><jats:ext-link xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="uri" xlink:href="http://clinicaltrials.gov">ClinicalTrials.gov</jats:ext-link> NCT03209258.

    <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>
