RESUMEN
OBJECTIVE: The impact of true first-pass effect (T-FPE, achieving substantial recanalization with extended thrombolysis in cerebral infarction; eTICI 3 after 1 thrombectomy) and outcomes on acute ischemic stroke (AIS) with large ischemic core remains uncertain. We aimed to study the association between T-FPE and outcomes in AIS patients with large core infarct through a real-world multicenter study. METHODS: From a prospective multicentric registry, we collected the data of all consecutive acute stroke patients with a large ischemic core who underwent thrombectomy and compared the outcomes of patients who achieved T-FPE and those who did not. In addition, we compared the outcomes of patients with different numbers of thrombectomy pass to identify the effectiveness of T-FPE. Multivariate analysis was performed to determine the predictors of T-FPE. The primary outcome was good functional outcome (modified Rankin Scale score; mRS 0-3) at 90 days. Safety outcomes included a 90-day mortality and symptomatic intracerebral hemorrhage within 48 hours after thrombectomy. RESULTS: Between November 2021 and February 2023, 447 eligible patients at 38 stroke centers were enrolled. Out of 447 thrombectomy patients, T-FPE was achieved in 102 individuals (22.8%). T-FPE was significantly associated with a higher proportion of good functional outcome (mRS 0-3 at 3 months, OR 2.221, 95% CI 1.418-3.479, p < 0.001) and lower mortality than non-T-FPE patients (31.4% vs. 45.5%, p = 0.012). The occlusion sites and lower DBP were strong predictors of T-FPE. INTERPRETATION: T-FPE was associated with favorable outcomes at 90 days in AIS patients with a large ischemic core who underwent EVT.
RESUMEN
Despite extensive research on the relationship between choline and cardiovascular disease (CVD), conflicting findings have been reported. We aim to investigate the relationship between choline and CVD. Our analysis screened a retrospective cohort study of 14,663 participants from the National Health and Nutrition Examination Survey conducted between 2013 and 2018. Propensity score matching and restricted cubic splines was used to access the association between choline intake and the risk of CVD. A two-sample Mendelian randomization (MR) analysis was conducted to examine the potential causality. Additionally, sets of single cell RNA-sequencing data were extracted and analyzed, in order to explore the role of choline metabolism pathway in the progression and severity of the CVD and the underlying potential mechanisms involved. The adjusted odds ratios and 95% confidence intervals for stroke were 0.72 (0.53-0.98; p = 0.035) for quartile 3 and 0.54 (0.39-0.75; p < 0.001) for quartile 4. A stratified analysis revealed that the relationship between choline intake and stroke varied among different body mass index and waist circumference groups. The results of MR analysis showed that choline and phosphatidylcholine had a predominantly negative causal effect on fat percentage, fat mass, and fat-free mass, while glycine had opposite effects. Results from bioinformatics analysis revealed that alterations in the choline metabolism pathway following stroke may be associated with the prognosis. Our study indicated that the consumption of an appropriate quantity of choline in the diet may help to protect against CVD and the effect may be choline-mediated, resulting in a healthier body composition. Furthermore, the regulation of the choline metabolism pathway following stroke may be a promising therapeutic target.

RESUMEN
Introduction: Symptomatic intracranial hemorrhage (sICH) is a serious complication of acute ischemic stroke (AIS) after endovascular treatment (EVT). Limited data exist regarding predictors and clinical implications of sICH after EVT, underscoring the significance of identifying risk factors to enhance prevention strategies. Therefore, the main objective of this study was to evaluate the incidence of sICH and identify its predictors after EVT in patients with large infarct core-AIS in the pre-circulation stage. Methods: Using data from the EVT for the Pre-circulation Large Infarct Core-AIS Study, we enrolled patients who were treated with EVT from the Prospective Multicenter Cohort Study of Early Treatment in Acute Stroke (MAGIC) registry. Baseline demographics, medical history, vascular risk factors, blood pressure, stroke severity, radiographic features, and EVT details were collected. The patients were classified into three groups: without intracranial hemorrhage (ICH), with asymptomatic intracranial hemorrhage (aICH), and sICH, based upon the occurrence of sICH. The main outcomes were the occurrence of sICH according to the Heidelberg Bleeding Classification and functional condition at 90 days. Multivariate logistic regression analysis and receiver operating characteristic (ROC) curves were used to identify independent predictors of sICH after EVT. Results: The study recruited a total of 490 patients, of whom 13.3% (n = 65) developed sICH. Patients with sICH had less favorable outcomes than those without intracranial hemorrhage (ICH) and those with aICH (13.8% vs. 43.5% vs. 32.2%, respectively; p < 0.001). The overall mortality was 41.8% (n = 205) at 90 days post-EVT. The univariate analysis revealed significant differences among the three groups in terms of blood glucose levels at admission, probability of favorable outcomes, incidence of brain herniation, and 90-day mortality. The multifactorial logistic regression analysis revealed that the blood glucose level at admission [odds ratio (OR) 1.169, p < 0.001, confidence interval (CI) 1.076-1.269] was an independent predictor of sICH. A blood glucose level of 6.95 mmol/L at admission was the best predictor of sICH, with an area under the ROC curve (AUC) of 0.685 (95% CI: 0.616-0.754). Discussion: The study findings demonstrated that the probability of sICH after EVT was 13.3% in patients with pre-circulation large infarct core-AIS, and sICH increased the risk of an unfavorable prognosis. Higher blood glucose levels at admission were associated with sICH after EVT in patients with pre-circulation large infarct core AIS. These findings underscore the importance of early management strategies to mitigate this risk.
RESUMEN
Importance: The association of endovascular therapy (EVT) with outcomes is unclear for patients with very low Alberta Stroke Program Early Computed Tomography Score (ASPECTS) within 24 hours of stroke onset. Objective: To explore the association of EVT with functional and safety outcomes among patients with ASPECTS of 0 to 2 scored with noncontrast computed tomography. Design, Setting, and Participants: This cohort study used data from an ongoing, prospective, observational, nationwide registry including all patients treated at 38 stroke centers in China with an occlusion in the internal carotid artery or M1 or M2 segment of the middle cerebral artery within 24 hours of witnessed symptom onset. Patients with ASPECTS of 0 to 2 between November 1, 2021, and February 8, 2023, were included in analysis. Data were analyzed October to November 2023. Exposures: EVT vs standard medical treatment (SMT). Main Outcomes and Measures: The primary outcome was favorable functional outcome, defined as modified Rankin Scale score (mRS) of 0 to 3, at 90 days. Safety outcomes included symptomatic intracerebral hemorrhage (sICH) within 48 hours and mortality at 90 days. Results: A total of 245 patients (median [IQR] age, 71 [63-78] years; 118 [48%] women) with ASPECTS of 0 to 2 were included, of whom 111 patients (45.1%) received SMT and 135 patients (54.9%) received EVT. The EVT group had significantly greater odds of favorable functional outcome at 90 days than the SMT group (30 patients [22.2%] vs 11 patients [9.9%]; P = .01; adjusted odds ratio [aOR], 3.07 [95% CI, 1.29-7.31]; P = .01). Patients in the EVT group, compared with the SMT group, had significantly greater odds of any ICH (56 patients [41.5%] vs 16 patients [11.4%]; P < .001; aOR, 4.27 [95% CI, 2.19-8.35]; P < .001) and sICH (24 patients [17.8%] vs 1 patient [0.9%]; P < .001; aOR, 23.07 [95% CI, 2.99-177.79]; P = .003) within 48 hours. There were no differences between groups for 90-day mortality (80 patients [59.3%] vs 59 patients [53.2%]; P = .34; aOR, 1.38 [95% CI, 0.77-2.47]; P = .28). The results remained robust in the propensity score-matched analysis. Conclusions and Relevance: In this cohort study of patients with very low ASPECTS based on NCCT within 24 hours of stroke onset, those treated with EVT had higher odds of a favorable functional outcome compared with those who received SMT. Randomized clinical trials are needed to assess these findings.

BACKGROUND: Despite the remarkable effectiveness of endovascular treatment (EVT), recent randomized controlled trials indicate that up to half of patients with large core infarction have a very poor outcome (modified Rankin Scale score 5-6 at 90 days). This study investigates the combined effect of Alberta Stroke Program Early CT Score (ASPECTS) and age on very poor outcome in patients with large core infarction treated with EVT. METHODS: This subanalysis of the MAGIC registry, which is a prospective, multicenter cohort study of early treatment in acute stroke, focused on patients with ASPECTS ≤5 presenting within 24 hours of stroke onset and receiving CT followed by EVT from November 1, 2021 to February 8, 2023. Multivariable logistic regression was used to investigate the independent and joint association of ASPECTS and age with very poor outcome. RESULTS: Among the 490 patients (57.3% men; median (IQR) age 69 (59-78) years), very poor outcome occurred more frequently in those with lower ASPECTS (65.2% in ASPECTS 0-2 vs 43.4% in ASPECTS 3-5; P<0.001). The predictive value of successful recanalization for very poor outcome was significant in patients with ASPECTS 3-5 (P=0.010), but it diminished in those with ASPECTS 0-2 (P=0.547). Compared with patients with ASPECTS 3-5 and age ≤69 years, the risk of a very poor outcome increased incrementally in those with lower ASPECTS, advanced age, or both (P<0.05). Graphical plot analysis showed a significantly lower probability of very poor outcome in younger patients (≤69 years) compared with older patients (>69 years) across all ASPECTS points. CONCLUSION: These findings suggest prioritizing young patients as candidates for EVT in those with ASPECTS 0-2.
RESUMEN
BACKGROUND AND OBJECTIVES: Previous studies have demonstrated the association between the procedure time (PT) and outcomes for patients with proximal large vessel occlusion; however, whether the relationship remains for patients with acute basilar artery occlusion (ABAO) was not clear. We aimed to characterize the association between PT and other procedure-related variables on clinical outcomes among patients with ABAO who underwent endovascular treatment (EVT). METHODS: Patients with ABAO who underwent EVT with a documented PT in the EVT for Acute Basilar Artery Occlusion (BASILAR) study from January 2014 to May 2019 among 47 comprehensive centers in China were included. Multivariable analysis was performed to reveal the association between PT and 90-day modified Rankin Scale score, mortality, complications, and all-cause death at 1 year. RESULTS: Of the 829 patients from the BASILAR registry, 633 eligible patients were included. Longer PT were associated with a lower rate of favorable outcome (by 30 minutes, adjusted OR 0.82 [95% CI 0.72-0.93], p = 0.01). In addition, a PT ≤ 75 minutes was associated with a favorable outcome (adjusted OR 2.03 [95% CI 1.26-3.28]). The risk of complications and mortality increased by 0.5% and 1.5% with every 10 minutes increase in PT, respectively (R2 = 0.64 and R2 = 0.68, p < 0.01). The cumulative rates of favorable outcomes and successful recanalization plateaued after 120 minutes (2 attempts). Restricted cubic spline regression analysis for the probability of favorable outcomes had an L-shape association (p nonlinearity = 0.01) with PT with significant benefit loss before 120 minutes and then appeared relatively flat. DISCUSSION: For patients with ABAO, procedures that exceeded 75 minutes were associated with an increased risk of mortality and lower odds of a favorable outcome. A careful assessment of futility and the risks of continuing the procedure should be made after 120 minutes.
