Introduction: We sought to assess the utility of intravenous thrombolysis (IVT) treatment in acute ischemic stroke (AIS) patients with unclear symptom onset time or outside the 4.5 hour time window, selected by advanced neuroimaging. Methods: We performed random-effects meta-analyses on the unadjusted and adjusted for potential confounders associations of IVT (alteplase 0.9 mg/kg) with the following outcomes: 3-month favorable functional outcome [FFO, modified Rankin Scale (mRS) scores: 0-1], 3-month functional independence (FI, mRS-scores: 0-2), 3-month mortality, 3-month functional improvement (assessed with ordinal analysis on the mRS-scores), symptomatic intracranial hemorrhage (sICH) and complete recanalization (CR). Results: We identified 4 eligible RCTs (859 total patients). In unadjusted analyses IVT was associated with higher likelihood of 3-month FFO (OR=1.48, 95%CI:1.12-1.96), FI (OR=1.42, 95%CI:1.07-1.90), sICH (OR=5.28, 95%CI:1.35-20.68) and CR (OR=3.29, 95%CI:1.90-5.69), with no significant difference in the odds of all-cause mortality risk at three months (OR=1.75, 95%CI: 0.93-3.29). In the adjusted analyses IVT was also associated with higher odds of 3-month FFO (OR adj =1.62, 95%CI:1.20-2.20), functional improvement (OR adj =1.42, 95%CI: 1.11-1.81) and sICH (OR adj =6.22, 95%CI: 1.37-28.26). There was no association between IVT and FI (OR adj =1.61, 95%CI: 0.94-2.75) or all-cause mortality at three months (OR adj =1.75, 95%CI: 0.93-3.29). No evidence of heterogeneity was evident in any of the analyses (I 2 =0). Conclusion: IVT in AIS patients with unknown symptom onset time or elapsed time from symptom onset more than 4.5 hours, selected with advanced neuroimaging, results in a higher likelihood of complete recanalization and functional improvement at three months despite the increased risk of sICH.

Abstract Background The effect of additional antimicrobial agents on the clinical outcomes of patients with idiopathic pulmonary fibrosis (IPF) is unclear. Methods We performed comprehensive searches of randomized control trials (RCTs) that compared the clinical efficacy of additional antimicrobial agents to those of placebo or usual care in the treatment of IPF patients. The primary outcome was all-cause mortality, and the secondary outcomes were changes in forced vital capacity (FVC), diffusing capacity of the lung for carbon monoxide (DLCO), and the risk of adverse events (AEs). Results Four RCTs including a total of 1055 patients (528 receiving additional antibiotics and 527 receiving placebo or usual care) were included in this meta-analysis. Among the study group, 402 and 126 patients received co-trimoxazole and doxycycline, respectively. The all-cause mortality rates were 15.0% (79/528) and 14.0% (74/527) in the patients who did and did not receive additional antibiotics, respectively (odds ratio [OR] 1.07; 95% confidence interval [CI] 0.76 to 1.51; p = 0.71). No significant difference was observed in the changes in FVC (mean difference [MD], 0.01; 95% CI − 0.03 to 0.05; p = 0.56) and DLCO (MD, 0.05; 95% CI − 0.17 to 0.28; p = 0.65). Additional use of antimicrobial agents was also associated with an increased risk of AEs (OR 1.65; 95% CI 1.19 to 2.27; p = 0.002), especially gastrointestinal disorders (OR 1.54; 95% CI 1.10 to 2.15; p = 0.001). Conclusions In patients with IPF, adding antimicrobial therapy to usual care did not improve mortality or lung function decline but increased gastrointestinal toxicity.

Background&Purpose: A recent meta-analysis investigating the association between statin pretreatment and early outcomes in patients with AIS indicated that pre-stroke statin treatment was associated with increased risk of 90-day mortality and symptomatic intracranial hemorrhage (sICH). We sought to investigate the potential association of statin pretreatment with early outcomes in a large, international registry of AIS patients treated with IVT. Subjects&Methods: We analyzed prospectively collected data from the Safe Implementation of Treatments in Stroke-East registry (SITS-EAST) on consecutive AIS patients treated with IVT during a seven-year period. We used three widely accepted definitions for sICH from NINDS-rtPA-Stroke Study, ECASS II trial and SITS registry. Dramatic clinical recovery (DCR) within 24 hours was defined as reduction in the baseline NIHSS-score of ≥10 points. Favorable functional outcome (FFO) at three months was defined as modified Rankin Scale score of 0-1. Results: We analyzed a total of 1660 AIS patients (mean age 67±13 years, median baseline NIHSS-score 11 points, interquartile range 5-16). Patients with statin pretreatment (n=373, 23%) had higher (p=0.019) baseline stroke severity compared to cases who had not received any statin at symptom onset. After adjusting for demographics, baseline stroke severity, onset-to-treatment time, history of previous stroke, risk factors, and admission blood pressure levels, statin pretreatment was not associated with a higher likelihood of sICH defined by the NINDS (OR: 1.41; 95%CI: 0.83-2.39; p=0.201), ECASS II (OR: 1.13; 95%CI: 0.60-2.14; p=0.712) or SITS (OR: 1.89; 95%CI: 0.75-4.77; p=0.178) criteria. Statin pretreatment was not related to three-month all-cause mortality (OR: 0.92; 95%CI: 0.57-1.49; p=0.741) or three-month FFO (OR: 0.81; 95%CI: 0.52-1.27; p=0.364). Statin pretreatment was independently associated with a higher odds of DCR (OR: 1.91; 95%CI: 1.25-2.92; p=0.003). Conclusions: Our findings indicate that statin therapy at symptom onset is not associated with adverse outcomes in AIS patients treated with IVT, while statin pretreatment almost doubles the likelihood of DCR during the first hours following tPA-infusion.

Abstract Aims The sex-related differences in the clinical outcomes of rhythm and safety after catheter ablation remain unclear. The purpose of this study was to compare the clinical outcomes of catheter ablation for atrial fibrillation (AF) in women and men. Methods and results The Medline and EMBASE databases were searched for published articles up to December 2018. Studies that met our predefined inclusion criteria were included. The primary endpoints were freedom from AF/atrial tachycardia (AT) recurrence, stroke/transient ischaemic attack (TIA), and all-cause mortality. After literature search and detailed assessment, 19 observational studies (151 370 patients; 34% women) were identified. Our analyses showed that the rate of freedom from AF/AT recurrence was lower in women than men at the 2.4-year follow-up [odds ratio (OR): 0.75, 95% confidence interval (CI) 0.69–0.81; P < 0.0001]. Moreover, women had an increased risk of stroke/TIA (OR: 1.42, 95% CI 1.21–1.67; P < 0.0001) and all-cause mortality (OR: 1.53, 95% CI 1.02–2.28; P = 0.04). Nevertheless, for the endpoint of all-cause mortality, there was no significant difference between the two genders in the subgroup of prospective studies (OR: 1.19, 95% CI 0.69–2.05; P = 0.53). Additionally, women were more likely to experience major complications compared with men (pericardial effusion/tamponade, major bleeding requiring transfusion, and pacemaker implantation). Conclusions Women who underwent catheter ablation of AF might experience lower efficacy and a higher risk of stroke/TIA and major complications than men. The reasons for these sex-related differences need to be further studied.

BackgroundEndovascular thrombectomy has demonstrated benefit for patients with acute ischemic stroke from proximal large vessel occlusion. However, limited evidence is available from recent randomized trials on the role of thrombectomy for M2 segment occlusions of the middle cerebral artery (MCA).MethodsWe conducted a systematic review and meta-analysis to investigate clinical and radiographic outcomes, rates of hemorrhagic complications, and mortality after M2 occlusion thrombectomy using modern devices, and compared these outcomes against patients with M1 occlusions. Recanalization was defined as Thrombolysis in Cerebral Infarction (TICI) 2b/3 or modified TICI 2b/3.ResultsA total of 12 studies with 1080 patients with M2 thrombectomy were included in our analysis. Functional independence (modified Rankin Scale 0–2) rate was 59% (95% CI 54% to 64%). Mortality and symptomatic intracranial hemorrhage rates were 16% (95% CI 11% to 23%) and 10% (95% CI 6% to 16%), respectively. Recanalization rates were 81% (95% CI 79% to 84%), and were equally comparable for stent-retriever versus aspiration (OR 1.05; 95% CI 0.91 to 1.21). Successful M2 recanalization was associated with greater rates of favorable outcome (OR 4.22; 95% CI 1.96 to 9.1) compared with poor M2 recanalization (TICI 0–2a). There was no significant difference in recanalization rates for M2 versus M1 thrombectomy (OR 1.05; 95% CI 0.77 to 1.42).ConclusionsThis meta-analysis suggests that mechanical thrombectomy for M2 occlusions that can be safely accessed is associated with high functional independence and recanalization rates, but may be associated with an increased risk of hemorrhage.

Background: Whether bridging treatment combining intravenous thrombolysis (IVT) and endovascular thrombectomy (EVT) is superior to direct EVT alone for emergent large vessel occlusion (LVO) in the anterior circulation is unknown. A systematic review and a meta-analysis were performed to investigate and assess the effect and safety of bridging treatment vs. direct EVT in patients with LVO in the anterior circulation.Methods: PubMed, EMBASE, and the Cochrane library were searched to assess the effect and safety of bridging treatment and direct EVT in LVO. Functional independence, mortality, asymptomatic and symptomatic intracranial hemorrhage (aICH and sICH, respectively), and successful recanalization were evaluated. The risk ratio and the 95% CI were analyzed.Results: Among the eight studies included, there was no significant difference in the long-term functional independence (OR = 1.008, 95% CI = 0.845–1.204, P = 0.926), mortality (OR = 1.060, 95% CI = 0.840–1.336, P = 0.624), recanalization rate (OR = 1.015, 95% CI = 0.793–1.300, P = 0.905), and the incidence of sICH (OR = 1.320, 95% CI = 0.931–1.870, P = 0.119) between bridging therapy and direct EVT. After adjusting for confounding factors, bridging therapy showed a lower recanalization rate (effect size or ES = −0.377, 95% CI = −0.684 to −0.070, P = 0.016), but there was no significant difference in the long-term functional independence (ES = 0.057, 95% CI = −0.177 to 0.291, P = 0.634), mortality (ES = 0.693, 95% CI = −0.133 to 1.519, P = 0.100), and incidence of sICH (ES = −0.051, 95% CI = −0.687 to 0.585, P = 0.875) compared with direct EVT. Meanwhile, in the subgroup analysis of RCT, no significant difference was found in the long-term functional independence (OR = 0.927, 95% CI = 0.727–1.182, P = 0.539), recanalization rate (OR = 1.331, 95% CI = 0.948–1.867, P = 0.099), mortality (OR = 1.072, 95% CI = 0.776–1.481, P = 0.673), and sICH incidence (OR = 1.383, 95% CI = 0.806–2.374, P = 0.977) between patients receiving bridging therapy and those receiving direct DVT.Conclusion: For stroke patients with acute anterior circulation occlusion and who are eligible for intravenous thrombolysis, there is no significant difference in the clinical effect between direct EVT and bridging therapy, which needs to be verified by more randomized controlled trials.

Objective:To provide a critical appraisal on the evidence from randomized-controlled clinical trials (RCTs) on the utility of direct endovascular treatment (dEVT) compared to the combination of endovascular treatment preceded by intravenous thrombolysis (bridging therapy, BT) for patients with acute large vessel occlusion (LVO).Methods:Eligible RCTs were identified by searching Medline and Scopus. We calculated the corresponding odds ratios (ORs) and 95% confidence intervals (95%CI) and pooled estimates using random-effects models. The primary outcome was the probability of modified Rankin scale (mRS) score of 0-2 at 3 months.Results:We included 3 studies comprising 1092 patients. No difference between dEVT and BT groups was detected for the outcomes of mRS 0-2 (OR=1.08,95%CI:0.85-1.38; adjusted OR=1.11, 95%CI:0.76-1.63), mRS 0-1 (OR=1.10, 95%CI:0.84-1.43; adjusted OR=1.16, 95%CI:0.84-1.61) and functional improvement at 3 months (common OR=1.08, 95%CI:0.88-1.34; adjusted common OR=1.09, 95%CI:0.86-1.37). Patients receiving dEVT had significantly lower likelihood of successful recanalization prior to the endovascular procedure compared to BT (OR=0.37, 95%CI:0.18-0.77). Patients receiving dEVT had lower intracranial bleeding rates compared to those receiving BT (OR=0.67, 95%CI:0.49-0.92), however, without significant difference in the probability of symptomatic intracranial hemorrhage. No differences in all-cause mortality, serious adverse events or procedural complications between the two groups were uncovered.Conclusions:We detected no differences in functional outcomes of IV thrombolysis eligible patients with an acute LVO receiving dEVT compared to BT. Since uncertainty for most endpoints remains large and the available data is not able to exclude the possibility of overall benefit or harm, further RCTs are needed.

Background: There is considerable evidence on the benefits of endovascular thrombectomy (EVT) for acute ischemic stroke (AIS) within 6 h after symptom onset. However, uncertainties remain regarding EVT efficacy beyond 6 h after symptom onset. We undertook a meta-analysis to assess the efficacy and safety of EVT in patients with AIS &gt;6 h after symptom onset.Methods: We searched PubMed, EMBASE, and Chinese Biomedical through July 2019. We included studies involving early (≤6 h) vs. delayed (&gt;6 h) EVT in selected patients with AIS, based on radiological evaluation criteria. Functional independence, successful recanalization, mortality, and symptomatic intracranial hemorrhage (sICH) rates were assessed.Results: Eight articles, with 3,265 patients who had undergone early EVT and 1,078 patients who had received delayed EVT, were included in the meta-analysis. Patients treated with early EVT showed a similar proportion of functional independence at 90 days [odds ratio (OR) = 1.14, 95% confidence interval (CI) = 0.926–1.397, P = 0.219; I2 = 36.2%, P = 0.128] as those treated with delayed EVT. Delayed EVT was also associated with no significant difference in mortality (OR = 1.015, 95% CI = 0.852–1.209; P = 0.871; I2 = 0.0%, P = 0.527), successful recanalization (OR = 1.255, 95% CI = 0.923–1.705; P = 0.147; I2 = 60.5%, P = 0.009), and sICH (OR = 0.976, 95% CI = 0.737–1.293; P = 0.871; I2 = 0.0%, P = 0.742) rates compared with early EVT.Conclusions: Among selected patients with AIS, delayed EVT showed comparable outcomes in functional independence, recanalization, mortality, and sICH rates compared with early EVT.

Abstract Background: Mitral regurgitation (MR) is a rather common valvular heart disease. The purpose of this meta-analysis is to compare the outcomes, and complications of mitral valve replacement (MVR) with surgical mitral valve repair (MVr) of non-ischemic MR (NIMR).Methods: MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials were searched through Oct 2020. 4834 studies were reviewed, and only 20 studies enrolling a total of 21,898 patients with NIMR were included. Eligible studies were enrolling patients with MR and reporting early (30-day or in-hospital) or late all-cause mortality. For each study, data regarding all-cause mortality and incidence of reoperation and operative complications in both groups were used to generate odds ratios (ORs) or hazard ratios (HRs). Results: The pooled analysis showed that lower age, rate of women and incident of hypertension, significantly rates of diabetes and atrial fibrillation in MVR group than MVr group, no significant difference in rates of pre-operative left ventricle ejection fraction (LVEF) and heart failure. Subjects in MVr group is slightly less than MVR group. Replacement of MR has significantly increased risk of early and late mortality. Moreover, the rate of re-operation and post-operative MR in MVr group is lower than MVR group.Conclusions: In patients with NIMR, MVr procedure achieves higher survival and fewer complications than surgical MVR. Given these results, MVr surgery should be a priority for NIMR patients.

Abstract Background The effect of additional antimicrobial agents on the clinical outcomes of patients with idiopathic pulmonary fibrosis (IPF) is unclear. Methods We performed comprehensive searches of randomized control trials (RCTs) that compared the clinical efficacy of additional antimicrobial agents to those of placebo or usual care in the treatment of IPF patients. The primary outcome was all-cause mortality, and the secondary outcomes were changes in forced vital capacity (FVC), diffusing capacity of the lung for carbon monoxide (DLCO), and the risk of adverse events (AEs). Results Four RCTs including a total of 1055 patients (528 receiving additional antibiotics and 527 receiving placebo or usual care) were enrolled in this meta-analysis. Among the study group, 402 and 126 patients received co-trimoxazole and doxycycline, respectively. The all-cause mortality rates were 15.0% (79/528) and 14.0% (74/527) in the patients who did and did not receive additional antibiotics, respectively (odds ratio [OR], 1.07; 95% confidence interval [CI], 0.76 to 1.51; p = 0.71). No significant difference was observed in the changes in FVC (mean difference [MD], 0.01; 95% CI, -0.03 to 0.05; p = 0.56) and DLCO (MD, 0.05; 95% CI, -0.17 to 0.28; p = 0.65). Additional use of antimicrobial agents was also associated with an increased risk of AEs (OR, 1.65; 95% CI, 1.19–2.27; p = 0.002), especially gastrointestinal disorders (OR, 1.54; 95% CI, 1.10–2.15; p = 0.001). Conclusion In patients with IPF, adding antimicrobial therapy to usual care did not improve mortality or lung function decline but increased gastrointestinal toxicity.
