RESUMEN
Background and purpose: The efficacy of intravenous thrombolysis (IVT) in patients with acute minor ischaemic stroke (AMIS) remains unclear. We performed a meta-analysis to compare the efficacy and safety of IVT and dual antiplatelet therapy (DAPT) in patients with AMIS. Methods: The Embase, Cochrane Library, PubMed, and Web of Science databases were searched up to 10 October, 2023. Prospective and retrospective studies comparing the clinical outcomes of IVT and DAPT were included. Odds ratios (ORs) and 95% confidence intervals (CIs) for early neurological deterioration (END), excellent and favourable functional outcomes, recurrent ischaemic stroke at 3 months, mortality at 3 months, and symptomatic intracranial haemorrhage (ICH) were pooled using a random-effects model. Results: Of the five included studies, 6,340 patients were included. In patients with AMIS, IVT was not significantly associated with excellent and favourable functional outcomes, recurrent ischaemic stroke, or all-cause mortality at 3 months compared to early DAPT. However, a higher risk of symptomatic ICH (OR, 9.31; 95% CI, 3.39-25.57) and END (OR, 2.75; 95% CI, 1.76-4.30) were observed with IVT. Conclusion: This meta-analysis indicated that IVT was not superior to DAPT in patients with AMIS, especially in those with nondisabling AIS. However, these findings should be interpreted with caution and have some limitations. Further, well-designed randomised controlled trials are warranted.
RESUMEN
BACKGROUND AND PURPOSE: Intravenous Thrombolysis (IVT) prior to Mechanical Thrombectomy (MT) for Acute Ischaemic Stroke (AIS) due to Large-Vessel Occlusion (LVO) remains controversial. Therefore, the authors performed a meta-analysis of the available real-world evidence focusing on the efficacy and safety of Bridging Therapy (BT) compared with direct MT in patients with AIS due to LVO. METHODS: Four databases were searched until 01 February 2023. Retrospective and prospective studies from nationwide or health organization registry databases that compared the clinical outcomes of BT and direct MT were included. Odds Ratios (ORs) and 95 % Confidence Intervals (CIs) for efficacy and safety outcomes were pooled using a random-effects model. RESULTS: Of the 12 studies, 86,695 patients were included. In patients with AIS due to LVO, BT group was associated with higher odds of achieving excellent functional outcome (modified Rankin Scale score 0-1) at 90 days (OR = 1.48, 95 % CI 1.25-1.75), favorable discharge disposition (to the home with or without services) (OR = 1.33, 95 % CI 1.29-1.38), and decreased mortality at 90 days (OR = 0.62, 95 % CI 0.56-0.70), as compared with the direct MT group. In addition, the risk of symptomatic intracranial hemorrhage did not increase significantly in the BT group. CONCLUSION: The present meta-analysis indicates that BT was associated with favorable outcomes in patients with AIS due to LVO. These findings support the current practice in a real-world setting and strengthen their validity. For patients eligible for both IVT and MT, BT remains the standard treatment until more data are available.

RESUMEN
OBJECTIVE: Acute ischemic stroke (AIS) is a severe, life-threatening type of stroke with poor prognosis and high recurrence rate, mainly attributed to large vessel occlusion (LVO). Improved understanding of the safety and effectiveness of the Soft Torqueable Catheter Optimized For Intracranial Access (SOFIA) for LVO-AIS might guide practitioners. Therefore, we conducted this study focusing on neurological outcomes, procedure-related complications, and recanalization rates. METHODS: We collected data in January 2022 from PubMed, Cochrane, Web of Science, and Embase. The study considered that assessed the effects of the SOFIA catheter in treatment of LVO-AIS. We extracted data narratively and expressed the results with the proportions and 95% confidence intervals (CI). RESULTS: We included 17 studies reporting on 2106 patients treated with the SOFIA catheter. The successful recanalization rate was 77% (95% CI, 71%-83%) with the SOFIA catheter alone and the application of a rescue stent-retriever was observed in 28% (95% CI, 23%-33%) of cases, resulting in an overall successful recanalization rate of 90% (95% CI, 87%-92%). A pooled estimate of 45% (95% CI, 39%-51%) was observed for functional independence at 90 days, 15% (95% CI, 11%-20%) for mortality at 90 days, and 5% (95% CI, 3%-8%) for symptomatic intracranial hemorrhage. CONCLUSIONS: This meta-analysis revealed that aspiration thrombectomy with the SOFIA catheter is a safer and effective treatment modality for LVO-AIS.

BACKGROUND: Evidence from sources outside the typical clinical research setting, such as a real-world setting, may complement evidence from randomised controlled trials (RCTs). The aim of the present study was to carry out a meta-analysis of available real-world evidence that focused on the efficacy and safety of endovascular treatment in patients with wake-up stroke (WUS) or daytime unwitnessed stroke (DUS) compared to that in patients treated ≤ 6 h after the onset of an ischemic stroke. METHODS: Data mining was conducted on 1 May 2021 from PubMed, EMBASE, and the Cochrane Central Register of Controlled Trials Cochrane Library. The study reviewed all published that assessed the effect of endovascular treatment in WUS and DUS compared to that received by patients with ischemic stroke. Relevant data were extracted and the narrative was reviewed and analysed. The results were expressed as odds ratios (ORs) with 95% confidence intervals (CIs). FINDINGS: The meta-analysis showed no significant differences between the two groups in the rates of functional independence (OR, 0.81; 95% CI, 0.65-1.02; P = 0.07), symptomatic intracerebral haemorrhage (OR, 0.86; 95% CI, 0.57-1.30; P = 0.470), and all-cause mortality (OR, 0.92; 95% CI, 0.73-1.16; P = 0.50). There was also no heterogeneity between the trials. CONCLUSION: The pooled analysis provided evidence to support the use of endovascular treatment in WUS and DUS with favourable perfusion imaging. The meta-analysis confirmed the main findings of RCTs of endovascular treatment in WUS and DUS in a real-world setting and therefore strengthens the validity of this treatment strategy.

BACKGROUND: Evidence from outside the typical clinical research setting, such as the real-world setting, complements evidence coming from randomized controlled trials. The purpose of this study was to evaluate all available evidence from the real-world observational trials about long-term outcomes of treatment with intravenous (IV) recombinant tissue-type plasminogen activator (rt-PA) compared with not treated with IV rt-PA (non-rt-PA) in patients with acute ischemic stroke. METHODS: We searched PubMed and Embase until March 1, 2018 for observational studies reporting matched or adjusted results comparing IV rt-PA versus non-rt-PA in patients with acute ischemic stroke. Outcomes assessed included all-cause mortality, hospital readmission rates, and independence rates. Hazard ratios with 95% confidence intervals were used as a measure of comparing between patients treated with IV rt-PA and non-rt-PA. RESULTS: Six observational trials with 16,399 participants were identified. The use of IV rt-PA in acute ischemic stroke patients was associated with a lower risk of mortality (hazard ratio .61; 95% confidence interval, .52-.70; P < .00001), and there was no heterogeneity across trials. There was no evidence of an effect on hospital readmission rates and independence rates. CONCLUSIONS: IV rt-PA is associated with reduced long-term mortality in acute ischemic stroke patients.

AIM: This meta-analysis aimed to assess the effect of high-frequency repetitive transcranial magnetic stimulation (HF-rTMS) for the treatment of depression in patients with Parkinson's disease (PD). METHODS: The design was a meta-analysis of randomized controlled trials (RCTs). The participants were patients with PD who suffered from depression. The interventions were HF-rTMS alone or in combination with other treatments compared with sham-rTMS, placebo, and anti-depressant treatments. The primary outcome measure was changes in depressive symptoms, defined as the mean change in the total depression score. The secondary outcome was changes in motor symptoms, defined by Unified Parkinson's Disease Rating Scale part III scores, and the acceptability, defined as the risk of all-cause discontinuation. These were expressed as mean differences (MDs), standardized mean differences (SMDs), or risk ratios (RRs) with 95% confidence intervals (CIs). RESULTS: We identified nine suitable trials, with data from 332 participants. For the patients with depression in PD, HF-rTMS was not better than sham-rTMS (SMD =-0.33, 95% CI -0.83 to 0.17) or selective serotonin re-uptake inhibitors (SSRIs) (SMD =0.07, 95% CI -0.52 to 0.18) for the treatment of depressive symptoms. However, the motor benefits after treatment with HF-rTMS might be better than sham-rTMS (MD =-2.80, 95% CI -5.45 to -0.15) and SSRIs (MD =-2.70, 95% CI -4.51 to -0.90). CONCLUSION: This meta-analysis provides some evidence that in patients with PD with depression, HF-rTMS may lead to improvement in motor function but not in depression compared with sham-rTMS or SSRIs.
