Publication Diffusion-weighted imaging as predictor of acute ischemic stroke etiology(2022) brunser, alejandro; Mansilla, Eloy; NAVIA, VICTOR; Mazzon, Enrico; Rojo, Alexis; Cavada, Gabriel; Olavarría, Verónica V.; Munoz Venturelli, Paula; Lavados, PabloBackground: Topographic patterns may correlate with causes of ischemic stroke. Objective: To investigate the association between diffusion weighted imaging (DWI) and Trial of Org 10172 in Acute Stroke Treatment (TOAST) classification. Methods: We included 1019 ischemic stroke patients. DWI were classified as: i) negative; ii) DWI single lesion (cortico-subcortical, cortical, subcortical ≥20 mm, or subcortical <20 mm); iii) scattered lesions in one territory (small scattered lesions or confluent with additional lesions); and iv) multiple lesions (multiple unilateral anterior circulation [MAC], multiple posterior circulation [MPC], multiple bilateral anterior circulation [MBAC], and multiple anterior and posterior circulations [MAP]). Results: There was a relationship between DWI patterns and TOAST classification (p<0.001). Large artery atherosclerosis was associated with small, scattered lesions in one vascular territory (Odds Ratio [OR] 4.22, 95% confidence interval [95%CI] 2.61–6.8), MPC (OR 3.52; 95%CI 1.54–8.03), and subcortical lesions <20 mm (OR 3.47; 95%CI 1.76–6.85). Cardioembolic strokes correlated with MAP (OR 4.3; 95%CI 1.64–11.2), cortico-subcortical lesions (OR 3.24; 95%CI 1.9–5.5) and negative DWI (OR 2.46; 95%CI 1.1–5.49). Cryptogenic strokes correlated with negative DWI (OR 4.1; 95%CI 1,84–8.69), cortical strokes (OR 3.3; 95%CI 1.25–8.8), MAP (OR 3.33; 95%CI 1.25–8.81) and subcortical lesion ≥20 mm (OR 2.44; 95%CI 1,04–5.73). Lacunar strokes correlated with subcortical lesions diameter <20 mm (OR 42.9; 95%CI 22.7–81.1) and negative DWI (OR 8.87; 95%CI 4.03–19.5). Finally, MBAC (OR 9.25; 95%CI 1.12–76.2), MAP (OR 5.54; 95%CI 1.94–15.1), and MPC (OR 3.61; 95%CI 1.5–8.7) correlated with stroke of other etiologies. Conclusions: A relationship exists between DWI and stroke subtypePublication Who is in the emergency room matters when we talk about door-to-needle time: a single-center experience [Quien está en el servicio de emergencia importa al hablar de tiempo puerta-aguja: experiencia de un centro clínico](2023) brunser, alejandro; Nuñez; Juan; Mansilla, Eloy; Cavada, Gabriel; Olavarría, Verónica V.; Munoz Venturelli, Paula; Lavados, PabloBackground: The efficacy of intravenous thrombolysis (IVT) is time-dependent. Objective: To compare the door-to-needle (DTN) time of stroke neurologists (SNs) versus non-stroke neurologists (NSNs) and emergency room physicians (EPs). Additionally, we aimed to determine elements associated with DTN ≤ 20 minutes. Methods: Prospective study of patients with IVT treated at Clínica Alemana between June 2016 and September 2021. Results: A total of 301 patients underwent treatment for IVT. The mean DTN time was 43.3 ± 23.6 minutes. One hundred seventy-three (57.4%) patients were evaluated by SNs, 122 (40.5%) by NSNs, and 6 (2.1%) by EPs. The mean DTN times were 40.8 ± 23, 46 ± 24.7, and 58 ± 22.5 minutes, respectively. Door-to-needle time ≤ 20 minutes occurred more frequently when patients were treated by SNs compared to NSNs and EPs: 15%, 4%, and 0%, respectively (odds ratio [OR]: 4.3, 95% confidence interval [95%CI]: 1.66–11.5, p = 0.004). In univariate analysis DTN time ≤ 20 minutes was associated with treatment by a SN ( p = 0.002), coronavirus disease 2019 pandemic period ( p = 0.21), time to emergency room (ER) ( p = 0.21), presence of diabetes ( p = 0.142), hypercholesterolemia ( p = 0.007), atrial fibrillation ( p < 0.09), score on the National Institutes of Health Stroke Scale (NIHSS) ( p = 0.001), lower systolic ( p = 0.143) and diastolic ( p = 0.21) blood pressures, the Alberta Stroke Program Early CT Score (ASPECTS; p = 0.09), vessel occlusion ( p = 0.05), use of tenecteplase ( p = 0.18), thrombectomy ( p = 0.13), and years of experience of the physician ( p < 0.001). After multivariate analysis, being treated by a SN (OR: 3.95; 95%CI: 1.44–10.8; p = 0.007), NIHSS (OR: 1.07; 95%CI: 1.02–1.12; p < 0.002) and lower systolic blood pressure (OR: 0.98; 95%CI: 0.96–0.99; p < 0.003) remained significant. Conclusion: Treatment by a SN resulted in a higher probability of treating the patient in a DTN time within 20 minutes.Publication Recommendations for Implementing the INTERACT3 CareBundle for Intracerebral Hemorrhagein Latin America: Results of a Delphi Method(2024) Allende, María Ignacia; Munoz Venturelli, Paula; González, Francisca; Bascur, Francisca; Craig S., Anderson; Ouyang, Menglu; Cabieses, Báltica; Obach, Alexandra; Cano-Nigenda, Vanessa; Arauz, Antonio; LATAM INTERACT3 Consensus Statement PanelIntroduction: 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.
