Publication Sex Differences in Profile and In-Hospital Death for Acute Stroke in Chile: Data From a Nationwide Hospital Registry(2024) Nuñez, Marilaura; Allende, María; González, Francisca; Cavada, Gabriel; Anderson, Craig; Munoz Venturelli, PaulaBackground: Knowledge of local contextual sex differences in the profile and outcome for stroke can improve service delivery. We aimed to determine sex differences in the profile of patients with acute stroke and their associations with in-hospital death in the national hospital database of Chile. Methods and results: We present a retrospective cohort based on the analysis of the 2019 Chilean database of Diagnosis-Related Groups, which represents 70% of the operational expenditure of the public health system. Random-effects multiple logistic regression models were used to determine independent associations of acute stroke (defined by main diagnosis International Classification of Diseases, Tenth Revision [ICD-10] codes) and in-hospital death, and reported with odds ratios (ORs) and 95% CIs. Of 1 048 575 hospital discharges, 15 535 were for patients with acute stroke (7074 [45.5%] in women), and 2438 (15.6%) of them died during hospitalization. Differences by sex in sociodemographic and clinical characteristics were identified for stroke and main subtypes. After fully adjusted model, women with ischemic stroke had lower in-hospital death (OR, 0.79 [95% CI, 0.69-0.91]) compared with men; other independent predictors included age per year increase (OR, 1.03 [95% CI, 1.03-1.04]), chronic kidney disease (OR, 1.47 [95% CI, 1.20-1.80]), atrial fibrillation (OR, 1.50 [95% CI, 1.26-1.80]), and other risk factors. Conversely, for intracerebral hemorrhage, women had a higher in-hospital mortality rate than men (OR, 1.19 [95% CI, 1.02-1.40]); other independent predictors included age per year increase (OR, 1.009 [95% CI, 1.003-1.01]), chronic kidney disease (OR, 1.55 [95% CI, 1.23-1.97]), oral anticoagulant use (OR, 1.88 [95% CI, 1.37-2.58]), and other risk factors. Conclusions: Sex differences in characteristics and in-hospital death of hospitalized patients exist for acute stroke in Chile. In-hospital death is higher for acute ischemic stroke in men and higher for intracerebral hemorrhage in women. Future research is needed to better identify contributing factors.Publication Risk and impact of stroke across 38 countries and territories of the Americas from 1990 to 2021: a population-based trends analysis from the Global Burden of Disease Study 2021(2025) Martinez, Ramón; Munoz Venturelli, Paula; Ordunez, Pero; Fregni, Felipe; Abanto, Carlos; Alet, Matias; Alvarez, Tony; Amaya, Pablo; Ameriso, Sebastian; Arauz, Antonio; Barboza, Miguel; Bayona, Hernán; Ortiz, Antonio; Calleja, Juan; Cano, Vanessa; Carbonera, Leonardo; Carrillo, Rodrigo; Corredor, Angel; De Souza, Ana; Jimenez, Claudio; Lanas, Fernando; Martins, Sheila; Navia, Víctor; Novarro, Nelson; Olavarría, Verónica V.; Ovbiagele, Bruce; Pachecho, Kevin; Pontes, Octavio; Pujol, Virginia; Rabinstein, Alejandro; Rosales, Julieta; Rosende, Andrés; Sampaio, Gisele; Saposnik, Gustavo; Sen, Souvik; Testai, Fernando; Urrutia, Victor; Anderson, Craig; Lavados, PabloBackground: Despite substantial declines in burden over time, stroke remains a public health threat in the Americas. This study aimed to assess the current magnitude, trends, and disparities in the estimates of stroke burden by sex and age in the Americas from 1990 to 2021. Methods: Estimates from the Global Burden of Disease, Injuries and Risk Factors Study 2021 were used to analyze incidence, prevalence, mortality, years of life lost due to premature death, years lived with disabilities, and disability-adjusted life years (DALYs) caused by stroke and its major subtypes stratified by age, and sex in the Americas from 1990 to 2021. We used Joinpoint regression analysis to estimate the average annual percent change (AAPC) of stroke mortality and disease burden outcomes and assessed trends. Findings: In 2021, there were 1.1 million (95% uncertainty interval: 1.0-1.2) new cases, 12.9 million (12.3-13.7) prevalent cases, 0.5 million (0.5-0.6) deaths, and 11.4 million (10.6-12.1) DALYs due to stroke in the Americas. The absolute number of stroke burden outcomes increased from 1990 to 2021, but their corresponding age-standardized rates significantly declined. A deceleration in reduction rates of burden outcomes for all strokes and most stroke subtypes occurred over the last decade, with pronounced difference between sexes mainly in incidence among younger groups. From 2015 to 2021, trends in incidence rates from all stroke and stroke subtypes reversed to increase in most age groups, and strikingly, trends in mortality and DALY rates from ischemic stroke among younger populations reversed to upward with AAPC over 1.4%. A substantial number of countries contributed to these increasing trends. Interpretation: Regionally, the annual number of stroke cases and deaths significantly increased from 1990 to 2021, despite reductions in age-standardized rates. The declining pace in age-standardized stroke rates has decelerated in recent years, while trends in incidence, and ischemic stroke mortality and DALY among middle-aged adults and adults, reversed towards upward in the period 2015-2021. Further studies are needed to understand the determinants of this recent pattern and identify the most cost-effective interventions to stem this alarming trend. Funding: There was no funding source for this study.Publication Recommendations for Implementing the INTERACT3 Care Bundle for Intracerebral Hemorrhage in Latin America: Results of a Delphi Method(2025) Allende, María; Munoz Venturelli, Paula; Gonzalez, Francisca; Bascur, Francisca; Anderson, Craig; Ouyang, Menglu; Cabieses, Báltica; Obach, Alexandra; Cano, Vanessa; Arauzg, AntonioIntroduction: The third Intensive Care Bundle with Blood Pressure Reduction in Acute Cerebral Hemorrhage Trial (INTERACT3) showed that the implementation of a care bundle improves outcomes after acute intracerebral hemorrhage (ICH). We aimed to establish consensus-based recommendations for the broader integration of the care bundle across Latin American countries (LAC). Methods: A 3-phase Delphi study allowed a panel of 32 healthcare workers from 14 LAC to sequentially rank statements relevant to 7 domains (training, resources/infrastructure, patient education, blood pressure, temperature, glycemic control, and anticoagulation reversal). The pre-defined consensus threshold was 75%. Results: A total of 43 statements reached consensus by the third round, with 12 new statements emerging through rounds. The highest-ranked statements in each domain emphasized critical aspects, but successful implementation requires appropriate resourcing. Key priorities were continuous training of all healthcare workers in ICH management, establishing protocols aligned with available resources, and collaborative interdisciplinary care supported by institutional networks. Statements related to anticoagulation reversal had the highest priority. Conclusions: Consensus statements are provided to facilitate integration of the INTERACT3 care bundle to reduce disparities in ICH outcomes in LAC.
