    Abstract: 〈 b 〉 〈 i 〉 Introduction: 〈 /i 〉 〈 /b 〉 The COVID-19 pandemic resulted in significant healthcare reorganizations, potentially striking standard medical care. We investigated the impact of the COVID-19 pandemic on acute stroke care quality and clinical outcomes to detect healthcare system’s bottlenecks from a territorial point of view. 〈 b 〉 〈 i 〉 Methods: 〈 /i 〉 〈 /b 〉 Crossed-data analysis between a prospective nation-based mandatory registry of acute stroke, Emergency Medical System (EMS) records, and daily incidence of COVID-19 in Catalonia (Spain). We included all stroke code activations during the pandemic (March 15–May 2, 2020) and an immediate prepandemic period (January 26–March 14, 2020). Primary outcomes were stroke code activations and reperfusion therapies in both periods. Secondary outcomes included clinical characteristics, workflow metrics, differences across types of stroke centers, correlation analysis between weekly EMS alerts, COVID-19 cases, and workflow metrics, and impact on mortality and clinical outcome at 90 days. 〈 b 〉 〈 i 〉 Results: 〈 /i 〉 〈 /b 〉 Stroke code activations decreased by 22% and reperfusion therapies dropped by 29% during the pandemic period, with no differences in age, stroke severity, or large vessel occlusion. Calls to EMS were handled 42 min later, and time from onset to hospital arrival increased by 53 min, with significant correlations between weekly COVID-19 cases and more EMS calls (rho = 0.81), less stroke code activations (rho = −0.37), and longer prehospital delays (rho = 0.25). Telestroke centers were afflicted with higher reductions in stroke code activations, reperfusion treatments, referrals to endovascular centers, and increased delays to thrombolytics. The independent odds of death increased (OR 1.6 [1.05–2.4], 〈 i 〉 p 〈 /i 〉 0.03) and good functional outcome decreased (mRS ≤2 at 90 days: OR 0.6 [0.4–0.9], 〈 i 〉 p 〈 /i 〉 0.015) during the pandemic period. 〈 b 〉 〈 i 〉 Conclusion: 〈 /i 〉 〈 /b 〉 During the COVID-19 pandemic, Catalonia’s stroke system’s weakest points were the delay to EMS alert and a decline of stroke code activations, reperfusion treatments, and interhospital transfers, mostly at local centers. Patients suffering an acute stroke during the pandemic period had higher odds of poor functional outcome and death. The complete stroke care system’s analysis is crucial to allocate resources appropriately.

    Abstract: 〈 b 〉 〈 i 〉 Background: 〈 /i 〉 〈 /b 〉 Collateral circulation may modify the effect of neuroprotective therapies. We report a post hoc analysis of the URICO-ICTUS trial (NCT00860366) assessing the modifying treatment effect of pretreatment collaterals on clinical and radiological outcomes in patients with large-vessel acute ischemic stroke receiving uric acid therapy or placebo. 〈 b 〉 〈 i 〉 Methods: 〈 /i 〉 〈 /b 〉 URICO-ICTUS was a randomized clinical trial where 411 alteplase-treated patients also received uric acid 1,000 mg ( 〈 i 〉 n 〈 /i 〉 = 211) or placebo ( 〈 i 〉 n 〈 /i 〉 = 200) before the end of alteplase infusion. Herein, we included a nested study of 84 patients (placebo = 40, uric acid = 44) who had a pretreatment CT-angiography (CTA) showing a proximal arterial occlusion in the carotid territory. Excellent collaterals were defined as 100% collateral supply on pretreatment CTA. Regression models assessed the interaction between therapy (uric acid/placebo) and collaterals on the main outcome (ordinal modified Rankin Scale [mRS] shift at 90 days). 〈 b 〉 〈 i 〉 Results: 〈 /i 〉 〈 /b 〉 Overall, excellent collaterals were associated with improved outcome. There was a significant interaction between therapy and pretreatment collaterals ( 〈 i 〉 p 〈 /i 〉 interaction = 0.02) for the prediction of improved mRS shift. The largest treatment contrast in favor of uric acid was found in patients with excellent collaterals (adjusted OR 9.2; 95% CI 1.23–68.6; 〈 i 〉 p 〈 /i 〉 = 0.03). 〈 b 〉 〈 i 〉 Conclusions: 〈 /i 〉 〈 /b 〉 Collectively, the study found that collaterals were associated with the neuroprotective effect of uric acid therapy highlighting the importance of assessing collateral status in neuroprotection trials.

    Abstract: 〈 b 〉 〈 i 〉 Background: 〈 /i 〉 〈 /b 〉 Among the acute ischemic stroke patients with large vessel occlusions and contraindications for the use of IV thrombolysis, mainly on oral anticoagulation or presenting too late, primary endovascular therapy is often performed as an alternative to the standard therapy even though evidence supporting the use of endovascular reperfusion therapies is not yet established. Using different statistical approaches, we compared the functional independence rates at 3 months among patients undergoing primary endovascular therapy and patients treated only with IV thrombolysis. 〈 b 〉 〈 i 〉 Methods: 〈 /i 〉 〈 /b 〉 We used data from a prospective, government-mandated and externally audited registry of reperfusion therapies for ischemic stroke (January 2011 to November 2012). Patients were selected if treated with either IV thrombolysis alone (n = 1,582) or primary endovascular thrombectomy (n = 250). A series of exclusions were made to homogenize the clinical characteristics among the two groups. We then carried out multivariate logistic regression and propensity score matching analyses on the final study sample (n = 1,179) to compare functional independence at 3 months, as measured by the modified Rankin scale scores 0-2, between the two groups. 〈 b 〉 〈 i 〉 Results: 〈 /i 〉 〈 /b 〉 The unadjusted likelihood of good outcome was poorer among the endovascular group (OR: 0.69; 95% CI: 0.47-1.0). After adjustment, no differences by treatment modality were seen (OR: 1.51; 95% CI: 0.93-2.43 for primary endovascular therapy). Patients undergoing endovascular thrombectomy within 180-270 min (OR: 2.89; 95% CI: 1.17-7.15) and patients with severe strokes (OR: 1.84; 95% CI: 1.02-3.35) did better than their intravenous thrombolysis counterparts. The propensity score-matched analyses with and without adjustment by additional covariates showed that endovascular thrombectomy was as effective as intravenous thrombolysis alone in achieving functional independence (OR for unadjusted propensity score matched: 1.35; 95% CI: 0.9-2.02, OR for adjusted propensity score matched: 1.45; 95% CI: 0.91-2.32). 〈 b 〉 〈 i 〉 Conclusion: 〈 /i 〉 〈 /b 〉 This comparative effectiveness study shows that in ischemic stroke patients with contraindications for IV thrombolysis, primary endovascular treatment might be an alternative therapy at least as effective as IV thrombolysis alone. Randomized controlled trials are urgently needed.

    Abstract: 〈 b 〉 〈 i 〉 Background: 〈 /i 〉 〈 /b 〉 A significant proportion of stroke patients presenting with mild symptoms does not have a successful recovery, especially when a large vessel is occluded. IV thrombolysis is safe and may benefit patients presenting with mild symptoms. In this study, we tested whether endovascular therapy (ET) is superior to medical therapy in these patients. 〈 b 〉 〈 i 〉 Methods: 〈 /i 〉 〈 /b 〉 Observational, prospectively collected, multicenter study of 78 consecutive patients admitted from 2009 to 2012 within 6 h of stroke, with NIHSS ≤5 at presentation or during initial diagnostic work-up and large vessel occlusion. Data for patients undergoing ET and/or IV thrombolysis were taken from the SONIIA registry of reperfusion therapies in Catalonia, or from our local stroke registry if no reperfusion therapy was delivered. We compared risk factors, clinical course, collateral circulation, revascularization rates, hemorrhagic complications, infarct volume, and the functional outcome at 3 months of patients treated with ET and those not receiving ET. Ordinal regression was used to assess the independent effect of ET on functional outcome. 〈 b 〉 〈 i 〉 Results: 〈 /i 〉 〈 /b 〉 Baseline characteristics were similar for ET (n = 34) and medically (n = 44) treated patients, except for older age in the latter. The occlusions were located in the terminal internal carotid artery (1%), M1 segment of the middle cerebral artery (33%), M2 segment (30%), posterior circulation (31%), and 5% of the patients had tandem lesions, with no significant differences between groups. Most patients in both treatment groups had good collateral flow. The rate of successful revascularization (91.2 vs. 63.4%; p = 0.006) and the risk of symptomatic intracranial hemorrhage (11.8 vs. 0%; p = 0.033) were higher in the ET group. The NIHSS scores were similar at hospital arrival, after initial neuroimaging, and at 24 h in both treatment groups and there were no significant differences in the infarct volume in a follow-up MRI. At 3 months, 35.9% of the patients had some disability. The functional outcome was similar in both treatment groups in univariate analysis and also in models adjusted for age and initial NIHSS or for variables associated to functional outcome on univariate comparison. Conversely, IV thrombolysis was associated with significantly greater chances of full recovery after adjusting for baseline differences (OR 3.70, p = 0.015). 〈 b 〉 〈 i 〉 Conclusions: 〈 /i 〉 〈 /b 〉 One third of stroke patients with mild symptoms and large vessel occlusions do not have a successful recovery. ET is effective to recanalize the occluded vessel but increases the risk of serious bleeding significantly without improving the functional outcome, and is therefore not justified routinely in these patients.
