We performed a systematic review and meta-analysis evaluating the efficacy and safety of first-line thrombectomy with combined techniques, which entail simultaneous use of a stent retriever and aspiration catheter, vs. single-device techniques, whether stent retriever or direct aspiration alone, for DMVO-AIS patients. Methods We systematically searched the PubMed, Embase and Cochrane CENTRAL databases from inception until 2 September 2022 for studies comparing combined and single-device techniques in DMVO-AIS patients. We adopted the Distal Thrombectomy Summit Group's definition of DMVO. Our outcomes were the modified first-pass effect [mFPE; modified Thrombolysis in Cerebral Infarction (mTICI) 2b-3 at first-pass], first-pass effect (FPE; mTICI 2c-3 at first-pass), successful and complete final reperfusion (mTICI 2b-3 and 2c-3 at end of all procedures, respectively), 90-day functional independence (modified Rankin scale 0-2), 90-day mortality, and symptomatic intracranial hemorrhage (sICH). Results Nine studies were included, with 477 patients receiving combined techniques, and 670 patients receiving single-device thrombectomy. Combined techniques achieved significantly higher odds of mFPE [odds ratio (OR), 2.12; 95% confidence interval (CI), 1.12–4.02; p = 0.021] and FPE (OR, 3.55; 95% CI, 1.97–6.38; p < 0.001), with lower odds of sICH (OR, 0.23; 95% CI 0.06–0.93; p = 0.040). There were no significant differences in final reperfusion, functional independence (OR, 1.19; 95% CI 0.87–1.63; p = 0.658), or mortality (OR, 0.94; 95% CI, 0.50–1.76; p = 0.850). Conclusions In DMVO-AIS patients, mechanical thrombectomy combining stent retrievers and aspiration catheters achieved higher odds of FPE and lower odds of sICH over single-device techniques. There were no differences in functional independence and mortality. Further trials are warranted to establish these findings.

Acute treatment strategies are centered around rescuing salvageable penumbra. Molecular imaging using positron emission tomography (PET) has shown higher sensitivity and specificity than CT and MRI in delineating penumbral tissues. In addition, PET imaging has identified the role of key inflammatory mediators in atherosclerosis, cellular damage, and recovery.

However, advanced imaging by either Magnet Resonance Imaging (MRI) or Computed Tomography Perfusion (CTP) is not available 24/7 at most stroke-centers. Therefore, the current review addresses the use of non-contrast CT (NCCT) to identify ischemic stroke patients suitable for IVT in the unknown or extended time-window in terms of efficacy and safety. Recent findings The current data on NCCT based IVT strategies in ischemic stroke patients presenting in the unknown or late time-window are relatively scarce and mainly provided by small retrospective samples. One larger registry (TRUST-CT) underlines the safety and efficacy of IVT without advanced imaging with more IVT-patients reaching an excellent outcome compared to the non-IVT treated control group. Current meta-analysis provides evidence that the rate of symptomatic intracerebral hemorrhage (sICH) is similar in the wake-up and unknown onset time-window compared to the 4.5 h time-window if patients are selected by NCCT. Results of the upcoming TWIST-trial investigating Tenecteplase (TNK) for NCCT-based IVT revealed no signals regarding an increased rate of sICH, however there was no benefit regarding functional outcomes. Summary So far, it is not well-established whether advanced imaging is indispensable and NCCT could be sufficient to identify stroke patients in the extended window who would benefit from IVT-treatment. However, current data suggests the safety of NCCT-based IVT in the extended time-window. Therefore, unavailable advanced neuroimaging should not cause delay, or even exclusion of patients from IVT and other recanalizing therapies per se.","PeriodicalId":73108,"journal":{"name":"Frontiers in stroke","volume":"52 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78311950","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As the incidence of ischemic stroke continues to rise globally, it is crucial to examine the mechanisms of the various proteins and molecules contributing to worsened patient outcome and recovery. Cathepsin L, a cysteine protease known for degrading tissues in lysosomes and elsewhere, may play a role in brain tissue loss and inflammation after stroke. Studies have suggested that cathepsin L appears in the ischemic core shortly after stroke is induced. Using immunohistochemical staining, mass spectrometry, and other assays, the increase of cathepsin L in the brain was correlated with extracellular matrix and perlecan degradation after ischemic stroke. Additionally, injection of a cathepsin L inhibitor significantly reduced brain infarct size and improved functional scores. More research is needed to elucidate cathepsin L's role in post-stroke inflammation and brain damage, in order to further explore the factors contributing to worsened patient outcome after ischemic stroke and work toward finding better therapeutic interventions.","PeriodicalId":73108,"journal":{"name":"Frontiers in stroke","volume":"20 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78546646","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Both treatments are highly time dependent, as faster treatment results in better outcomes. Utilization of both of these treatments is less than optimal, and treatment times continue to exceed the recommended benchmarks. An improvement intervention was launched across Atlantic Canada, which has four provinces: Nova Scotia (NS), New Brunswick (NB), Prince Edward Island (PEI), and Newfoundland and Labrador (NL). The intervention was conducted through the ACTEAST (Atlantic Canada Together Enhancing Acute Stroke Treatment) Project, which aimed to improve access and efficiency of treatment for acute ischemic stroke patients. Intervention and methods The improvement intervention was a 6-month virtual Improvement Collaborative that consisted of each stroke center assembling an interdisciplinary team, 2 full-day Learning Sessions, five to six 1-h webinars, and a site visit for each team. The Improvement Collaborative intervention was implemented using a stepped-wedge trial design, where the intervention was delivered in 3 phases. The Improvement Collaborative was initially conducted with NS, followed by NB and PEI, and the final phase was with NL. The number of participants enrolled across all 34 hospitals were 98, 86, and 72 for NS, NB-PEI, and NL, respectively. The attendance at the Learning Sessions ranged from 43 to 81 across all 3 clusters. The attendance at webinars had a mean of 29.0 (SD 6.8), 26.0 (SD 6.3), and 19.0 (SD 8.5) for the NS, NB-PEI, and NL clusters respectively. (Anticipated) Results We anticipate that an additional 3–5% of ischemic stroke patients will receive thrombolysis, EVT, or both. Additionally, we anticipate a reduction of 10–15 min in door-to-needle times across the region. This will translate to an increase in the proportion of ischemic stroke patients that will be discharged home from acute care. Discussion High level of engagement is possible in an Improvement Collaborative Intervention when implemented using a stepped-wedge trial design. The highest level of engagement was observed in the NS cluster, which maybe because this province has the most established provincial stroke system. Physician engagement, a critical aspect of improvement, was high. COVID-19 restrictions likely led to lower attendance at site visits.","PeriodicalId":73108,"journal":{"name":"Frontiers in stroke","volume":"46 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73429870","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
