    Abstract: The AFFINITY trial (Assessment of Fluoxetine in Stroke Recovery) reported that oral fluoxetine 20 mg daily for 6 months after acute stroke did not improve functional outcome and increased the risk of falls, bone fractures, and seizures. After trial medication was ceased at 6 months, survivors were followed to 12 months post-randomization. This preplanned secondary analysis aimed to determine any sustained or delayed effects of fluoxetine at 12 months post-randomization. Methods: AFFINITY was a randomized, parallel-group, double-blind, placebo-controlled trial in adults (n=1280) with a clinical diagnosis of stroke in the previous 2 to 15 days and persisting neurological deficit who were recruited at 43 hospital stroke units in Australia (n=29), New Zealand (4), and Vietnam (10) between 2013 and 2019. Participants were randomized to oral fluoxetine 20 mg once daily (n=642) or matching placebo (n=638) for 6 months and followed until 12 months after randomization. The primary outcome was function, measured by the modified Rankin Scale, at 6 months. Secondary outcomes for these analyses included measures of the modified Rankin Scale, mood, cognition, overall health status, fatigue, health-related quality of life, and safety at 12 months. Results: Adherence to trial medication was for a mean 167 (SD 48) days and similar between randomized groups. At 12 months, the distribution of modified Rankin Scale categories was similar in the fluoxetine and placebo groups (adjusted common odds ratio, 0.93 [95% CI, 0.76–1.14]; P =0.46). Compared with placebo, patients allocated fluoxetine had fewer recurrent ischemic strokes (14 [2.18%] versus 29 [4.55%] ; P =0.02), and no longer had significantly more falls (27 [4.21%] versus 15 [2.35%] ; P =0.08), bone fractures (23 [3.58%] versus 11 [1.72%] ; P =0.05), or seizures (11 [1.71%] versus 8 [1.25%] ; P =0.64) at 12 months. Conclusions: Fluoxetine 20 mg daily for 6 months after acute stroke had no delayed or sustained effect on functional outcome, falls, bone fractures, or seizures at 12 months poststroke. The lower rate of recurrent ischemic stroke in the fluoxetine group is most likely a chance finding. Registration: URL: http://www.anzctr.org.au/ ; Unique identifier: ACTRN12611000774921.

    Abstract: To measure the global impact of COVID-19 pandemic on volumes of IV thrombolysis (IVT), IVT transfers, and stroke hospitalizations over 4 months at the height of the pandemic (March 1 to June 30, 2020) compared with 2 control 4-month periods. Methods We conducted a cross-sectional, observational, retrospective study across 6 continents, 70 countries, and 457 stroke centers. Diagnoses were identified by their ICD-10 codes or classifications in stroke databases. Results There were 91,373 stroke admissions in the 4 months immediately before compared to 80,894 admissions during the pandemic months, representing an 11.5% (95% confidence interval [CI] −11.7 to −11.3, p 〈 0.0001) decline. There were 13,334 IVT therapies in the 4 months preceding compared to 11,570 procedures during the pandemic, representing a 13.2% (95% CI −13.8 to −12.7, p 〈 0.0001) drop. Interfacility IVT transfers decreased from 1,337 to 1,178, or an 11.9% decrease (95% CI −13.7 to −10.3, p = 0.001). Recovery of stroke hospitalization volume (9.5%, 95% CI 9.2–9.8, p 〈 0.0001) was noted over the 2 later (May, June) vs the 2 earlier (March, April) pandemic months. There was a 1.48% stroke rate across 119,967 COVID-19 hospitalizations. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection was noted in 3.3% (1,722/52,026) of all stroke admissions. Conclusions The COVID-19 pandemic was associated with a global decline in the volume of stroke hospitalizations, IVT, and interfacility IVT transfers. Primary stroke centers and centers with higher COVID-19 inpatient volumes experienced steeper declines. Recovery of stroke hospitalization was noted in the later pandemic months.

    Abstract: Patients with minor acute ischemic stroke or transient ischemic attack are at high risk for subsequent stroke, and more potent antiplatelet therapy in the acute setting is needed. However, the potential benefit of more intense antiplatelet therapy must be assessed in relation to the risk for major bleeding. The SOCRATES trial (Acute Stroke or Transient Ischemic Attack Treated With Aspirin or Ticagrelor and Patient Outcomes) was the first trial with ticagrelor in patients with acute ischemic stroke or transient ischemic attack in which the efficacy and safety of ticagrelor were compared with those of aspirin. The main safety objective was assessment of PLATO (Platelet Inhibition and Patient Outcomes)–defined major bleeds on treatment, with special focus on intracranial hemorrhage (ICrH). Methods: An independent adjudication committee blinded to study treatment classified bleeds according to the PLATO, TIMI (Thrombolysis in Myocardial Infarction), and GUSTO (Global Use of Strategies to Open Occluded Coronary Arteries) definitions. The definitions of ICrH and major bleeding excluded cerebral microbleeds and asymptomatic hemorrhagic transformations of cerebral infarctions so that the definitions better discriminated important events in the acute stroke population. Results: A total of 13 130 of 13 199 randomized patients received at least 1 dose of study drug and were included in the safety analysis set. PLATO major bleeds occurred in 31 patients (0.5%) on ticagrelor and 38 patients (0.6%) on aspirin (hazard ratio, 0.83; 95% confidence interval, 0.52–1.34). The most common locations of major bleeds were intracranial and gastrointestinal. ICrH was reported in 12 patients (0.2%) on ticagrelor and 18 patients (0.3%) on aspirin. Thirteen of all 30 ICrHs (4 on ticagrelor and 9 on aspirin) were hemorrhagic strokes, and 4 (2 in each group) were symptomatic hemorrhagic transformations of brain infarctions. The ICrHs were spontaneous in 6 and 13, traumatic in 3 and 3, and procedural in 3 and 2 patients on ticagrelor and aspirin, respectively. In total, 9 fatal bleeds occurred on ticagrelor and 4 on aspirin. The composite of ICrH or fatal bleeding included 15 patients on ticagrelor and 18 on aspirin. Independently of bleeding classification, PLATO, TIMI, or GUSTO, the relative difference between treatments for major/severe bleeds was similar. Nonmajor bleeds were more common on ticagrelor. Conclusions: Antiplatelet therapy with ticagrelor in patients with acute ischemic stroke or transient ischemic attack showed a bleeding profile similar to that of aspirin for major bleeds. There were few ICrHs. Clinical Trial Registration: URL: http://www.clinicaltrials.gov . Unique identifier: NCT01994720.

    Abstract: Advances in preoperative chemoradiotherapy and surgical techniques offered improvements in rates of locoregional recurrence but did not address distant metastasis. Traditionally, adjuvant chemotherapy has been administered with the goal of limiting systemic recurrences. Objective: Evaluation of the efficacy and safety of adjuvant chemotherapy in patients with locally advanced rectal cancer after preoperative chemoradiotherapy and surgery. Methods: From January 2017 to December 2018, 103 patients diagnosed with clinical stage II or III rectal cancer received adjuvant chemotherapy with capecitabine or XELOX regimens after neoadjuvant concurrent chemoradiotherapy and total mesorectal excision. Overall survival, disease-free survival, and toxicity were analyzed. Results: The median follow-up time was 52.5 months (6.5–66.8 months). The mean 3-year disease-free survival and 3-year overall survival were 86.2% (95% CI: 82.8–89.6) and 92.2% (95% CI: 86.9–97.5), respectively. The rate of hematologic and nonhematologic toxicity was low, mostly grades 1 and 2 including anemia, leucopenia, thrombocytopenia, and liver enzymes elevations were 85.4, 50.5, 42.8, and 45.6%, respectively. Conclusion: The capecitabine and XELOX regimen in adjuvant settings for rectal cancer patients receiving neoadjuvant chemoradiotherapy and surgery was a safe and effective modality. Further randomized trials need to be conducted to evaluate the role of postoperative therapy for these individuals.

    Abstract: Stroke is the leading cause of death and disability in Vietnam. This review aims to assess the current status of the stroke care system and quality criteria in the acute phase at stroke hospitals. In 2016, the Ministry of Health in Vietnam issued Circular 47, a mandate to build stroke units in Vietnam. The ANGELS program, which is supporting the World Stroke Organization to gain its goals, was implemented in 18 stroke‐ready hospitals in Vietnam to help address quality of stroke patient care in 2017. From the results achieved, we will continue to improve policies, strive to reach stroke benchmark goals, as well as plan to implement solutions in the future to build a better stroke system of care infrastructure in Vietnam.

    Abstract: Despite the well-established potent benefit of mechanical thrombectomy (MT) for large vessel occlusion (LVO) stroke, access to MT has not been studied globally. We conducted a worldwide survey of countries on 6 continents to define MT access (MTA), the disparities in MTA, and its determinants on a global scale. Methods: Our survey was conducted in 75 countries through the Mission Thrombectomy 2020+ global network between November 22, 2020, and February 28, 2021. The primary end points were the current annual MTA, MT operator availability, and MT center availability. MTA was defined as the estimated proportion of patients with LVO receiving MT in a given region annually. The availability metrics were defined as ([current MT operators×50/current annual number of estimated thrombectomy-eligible LVOs]×100 = MT operator availability) and ([current MT centers×150/current annual number of estimated thrombectomy-eligible LVOs] ×100= MT center availability). The metrics used optimal MT volume per operator as 50 and an optimal MT volume per center as 150. Multivariable-adjusted generalized linear models were used to evaluate factors associated with MTA. Results: We received 887 responses from 67 countries. The median global MTA was 2.79% (interquartile range, 0.70–11.74). MTA was 〈 1.0% for 18 (27%) countries and 0 for 7 (10%) countries. There was a 460-fold disparity between the highest and lowest nonzero MTA regions and low-income countries had 88% lower MTA compared with high-income countries. The global MT operator availability was 16.5% of optimal and the MT center availability was 20.8% of optimal. On multivariable regression, country income level (low or lower–middle versus high: odds ratio, 0.08 [95% CI, 0.04–0.12]), MT operator availability (odds ratio, 3.35 [95% CI, 2.07–5.42] ), MT center availability (odds ratio, 2.86 [95% CI, 1.84–4.48]), and presence of prehospital acute stroke bypass protocol (odds ratio, 4.00 [95% CI, 1.70–9.42] ) were significantly associated with increased odds of MTA. Conclusions: Access to MT on a global level is extremely low, with enormous disparities between countries by income level. The significant determinants of MT access are the country’s per capita gross national income, prehospital LVO triage policy, and MT operator and center availability.

    Abstract: Southeast Asia accounts for approximately 10% of stroke‐related mortalities worldwide, yet there are limited data regarding mechanical thrombectomy (MT) outcomes in this region. PROSPR‐SEA (Post‐Market Registry of Stroke Patients Treated With Medtronic Neurothrombectomy Devices to Collect Real‐World Data in Southeast Asia) assessed post‐market clinical outcomes of MT using the Solitaire Revascularization Device in southeast Asia. METHODS PROSPR‐SEA is a prospective, multicenter, nonrandomized, observational registry of patients who underwent MT using Solitaire as first line treatment at 1 of 10 centers in Vietnam, Thailand, and Singapore between January 2018 and July 2019. The primary end point was functional independence (modified Rankin scale 0–2) at 90 days. Safety end points included symptomatic intracerebral hemorrhage, emboli in new territory at 24 hours, and all‐cause mortality at 90 days. Secondary end points were successful revascularization (modified thrombolysis in cerebral infarction ≥2b), workflow metrics, National Institutes of Health Stroke Scale score at discharge, and patient disposition at 90 days. RESULTS A total of 183 patients (64.9±13.7, 49.7% [91/183] female) were included in the study and underwent MT; 79.2% (145/183) had occlusions in the middle cerebral artery. Median baseline National Institutes of Health Stroke Scale was 15.0 (range 1–31) and median baseline Alberta Stroke Program Early CT Score was 8.0 (range 0–10). Functional independence at 90 days was achieved in 62.2% (112/180). Mean puncture‐to‐revascularization time was 53.3±53.9 minutes, and mean onset‐to‐revascularization time was 330.0±110.4 minutes. Revascularization was successful in 94.0% (172/183) of patients. Median National Institutes of Health Stroke Scale improved at discharge (−8.0, range −22, 25) and 90 days (−13.0, range −22, 0). Within 24 hours, symptomatic intracerebral hemorrhage occurred in 7.7% (14/183) and emboli in new territory in 3.3% (6/183). At 90 days, the all‐cause mortality rate was 7.7% (14/183). Most patients were discharged to home by 90 days (84.1%, 154/183). CONCLUSION PROSPR‐SEA demonstrated high rates of positive functional outcomes and procedural success with a low mortality rate and indicates that the technical and clinical outcomes of landmark MT trials using Solitaire as the first‐line device are reproducible in real‐world southeast Asian settings.

    Abstract: Introduction: Global access to mechanical thrombectomy for large vessel occlusion (LVO) stroke is low and disparate between regions. Comparative global data on time metrics for imaging and endovascular treatment (EVT) performance, as well as the reasons for excluding EVT, are lacking. Methods: This is a cross-sectional study using quality metrics from the Res-Q registry on patients presenting directly to the hospital with acute ischemic stroke from January 1, 2022, to December 31, 2022, in countries with 200 or more cases. We used descriptive statistical methods to study the time metrics of interest including door to imaging and door to puncture. Additionally, reasons for not performing thrombectomy in patients with LVO were collected (Table 1). Results: Among the 153,181 patients from 912 hospitals across 67 countries enrolled in the Res-Q registry, 125,390 had an acute ischemic stroke. After excluding secondary transfers (n=26,648), patients with missing or erroneous data (n=42,232), and countries with less than 200 cases (n=1,626), data from a total of 54,884 patients from 631 hospitals across 30 countries were analyzed. CT angiography (CTA) was performed in 24,215 (44.1%) patients and EVT was done in 3,649 (6.6%) patients. For patients who had simultaneous CT+CTA, the median door-to-CTA time was 27.5 min (IQR 22.5-33.9) and the median door-to-puncture time was 98.5 (IQR 79.8-129.3) minutes. The most prevalent specific reason for excluding EVT in patients with LVO on CTA/MRA was the presentation in the late time window (42.0%). Only 11 (36.7%) countries achieved a median door-to-puncture time within 90 minutes (Table 1). Conclusions: The performance of acute imaging for LVO detection and time metrics for EVT appear to be disparate between countries and warrant further study. Additional data from global stroke care quality registries are needed to set benchmarks, compare regional stroke systems of care, and identify gaps to mobilize resources appropriately.

    Abstract: Introduction: Disparities in access to acute stroke care represents a major global challenge. Addressing such challenges requires a comprehensive understanding of the variations in stroke care quality between nations. Methods: We used data from the global Registry of Stroke Care Quality (RES-Q). RES-Q is web-based quality monitoring platform for the management of stroke care. Key quality metrics on patients with acute ischemic stroke admitted in 2022 were calculated: patients percentage arriving by Emergency Medical Services (EMS); patients percentage admitted to the Stroke Unit/Intensive Care Unit (ICU); Door-to-Imaging Time (DIT), Door-to-Needle Time (DNT) for intravenous thrombolysis. Results: Of 153 181 patients across 912 hospitals in 67 countries enrolled in the register, 125 390 had acute ischemic stroke. After excluding secondary transfers (n=26 648), missing or erroneous data (n=45 526), and countries with 〈 200 cases (n=1 410), a total of 51,806 patients from 696 hospitals and in 30 countries were analyzed. The percentage of patients arriving at healthcare facilities by EMS varied from 3% to 98% (median 51%; IQR 26-87) and admitted to the Stroke Units/ICUs from 25% to 99% (median 78%; IQR 47-89). The median DIT was 32; IQR 21-39, with range 10-60 minutes. The median DNT was 44; IQR 31-52, with range 20-71 minutes. Median DNT of patients admitted directly to the CT scanner was 24 minutes (IQR 15-38), and, if admitted to the emergency department, DNT was 39 minutes (IQR 25-55). Data by quartiles (best is blue, worst is red) from each country are presented in a detailed Table below. Conclusion: Our study underscores the critical role of the global registry in enabling cross-national comparative analyses of acute stroke care quality. The findings highlight disparities and variations in critical aspects of acute stroke care, paving the way for targeted interventions, policy reforms, and enhanced collaboration among stakeholders to improve stroke care globally.
