Introduction : Chronological heterogeneity in the neurological improvement after endovascular thrombectomy (EVT) for large vessel occlusion (LVO) stroke is commonly observed in clinical practice. Understanding the temporal progression of functional independence after EVT, especially delayed functional independence in patients who do not experience early improvement, is essential for prognostication and rehabilitation. We aim to determine the incidence of early and delayed functional independence and identify associated predictors after EVT. Methods : Demographic, clinical, radiological, treatment, and procedural information were analyzed from TREVO registry (patients undergoing EVT in the setting of anterior circulation LVO using the Trevo stent‐retriever). Incidence and predictors of early functional independence (EFI, modified Rankin Scale (mRS) score 0–2 at discharge) and delayed functional independence (DFI, mRS score 0–2 at 90 days in non‐EFI patients) were analyzed. Results : A total of 1757 patients met study criteria. EFI was observed in 45% (785) of patients. Among non‐EFI patients (972), DFI was observed in 34% (332) of patients. Younger age (p<0.001), lower blood glucose (p<0.001), mTICI > = 2B (p = 0.01), and lower total number of thrombectomy passes (p = 0.004) were independent predictors of DFI. Conclusions : Approximately 45% of patients experience early functional independence. One‐third of non‐early improvers experience delayed functional independence. Younger age, lower blood glucose, better collateral grade, and lower total number of passes were independent predictors of DFI among non‐early improvers. Further studies are required to improve our understanding of DFI. No upload

Incidence and predictors of early functional independence (EFI, modified Rankin Scale (mRS) score 0–2 at discharge) and delayed functional independence (DFI, mRS score 0–2 at 90 days in non-EFI patients) were analyzed.ResultsThree hundred and fifty-five patients met the study criteria. 55% were women and mean age was 71±15. Mean National Institutes of Health Stroke Scale (NIHSS) score was 17±6 and median Alberta Stroke Program Early CT Score was 9 (8-10). EFI was observed in 21% (73) of patients. Among non-EFI patients (282), DFI was observed in 30% (85) of patients. Shorter time to treatment (p=0.03), lower 24 hours NIHSS score (p<0.001), and smaller follow-up infarct volume (p=0.003) were independent predictors of EFI. Younger age (p=0.011), lower 24 hours NIHSS score (p=0.001), and absence of parenchymal hemorrhage (PH2; p=0.039) were independent predictors of DFI.ConclusionApproximately one-fifth of patients experience EFI and one-third of non-early improvers experience DFI. Younger age, lower 24 hours NIHSS score, and absence of parenchymal hemorrhage were independent predictors of DFI among non-early improvers.

Introduction: Heterogeneity in early neurological improvement after neurothrombectomy for large vessel occlusion (LVO) stroke is well documented. Delayed clinical recovery is observed in a subset of patients who do not experience early improvement. Understanding the temporality of clinical recovery after thrombectomy is essential in guiding prognostication and targeting rehabilitation. In this study, we aim to describe the characteristics and incidence of early and delayed clinical recovery and identify their predictors after LVO stroke thrombectomy. Methods: A retrospective analysis of prospectively-collected data on patients undergoing anterior circulation LVO stroke thrombectomy. Demographic characteristics, clinical and radiological data, treatment and procedural information were extracted and analyzed. Characteristics and predictors of early clinical recovery (ECR-1-NIHSS <6 at 24 hours and ECR-2-mRS 0-2 at discharge) and delayed clinical recovery (DCR-1 and 2- mRS 0-2 at 90 days) were analyzed. Statistical analyses were performed on SPSS 23 (IBM, Armonk, NY). Results: Three hundred and fifty-five patients met study criteria. 55% (195) were females and mean age was 71±15 years. Mean NIHSS score and median ASPECTS were 17±6 and 9 (8-10), respectively. ECR-1 and ECR-2 were observed in 31% (115) and 21% (73) patients, respectively. Among non-ECR patients, delayed recovery was observed in 27-30% of patients. Lower NIHSS [OR-0.83 (0.75-0.91), p=<0.01] and higher ASPECTS [OR-2.14, (1.29-3.54), p=0.003] scores were independent predictors of ECR-1 and younger age [OR-0.96 (0.94-0.99), p=0.01] and absence on parenchymal hemorrhage (PH) [OR-3.1 (1.3-7.1), p=0.007] were independent predictors of DCR-1. Among non-early improvers, patients <80 years and without PH have a 40% chance of DCR compared to no patients over 80 years with parenchymal hemorrhage experiencing DCR. Conclusion: About one-third of patients experience early clinical recovery (ECR-1-31%) and approximately one-third (DCR-1-30%) of non-early improvers experience delayed clinical recovery. Lower NIHSS score and higher ASPECTS predict ECR while younger age and absence of parenchymal hemorrhage predict DCR.

Background Three randomized clinical trials have reported similar safety and efficacy for contact aspiration (CA) and Stent-retriever (SR) thrombectomy. Aim We aimed to determine whether the Combined Technique (SR+CA) was superior to SR alone as first-line thrombectomy strategy in a patient cohort where balloon-guide catheter was universally used. Methods A prospectively maintained mechanical thrombectomy database from January 2018-December 2019 was reviewed. Patients were included if they had anterior circulation proximal occlusion ischemic stroke (intracranial ICA or MCA-M1/M2 segments) and underwent SR alone thrombectomy or SR+CA as first-line therapy. The primary outcome was the first-pass effect (FPE) (mTICI2c-3). Secondary outcomes included modified FPE (mTICI2b-3), successful reperfusion (mTICI2b-3) prior to and after any rescue strategy, and 90-day functional independence (mRS ≤2). Safety outcomes included rate of parenchymal hematoma (PH) type-2 and 90-day mortality. Sensitivity analyses were performed after dividing the overall cohort according to first-line modality into two matched groups. Results A total of 420 patients were included in the analysis (mean age 64.4 years; median baseline NIHSS 16[11-21]). As compared to first-line SR alone, first-line SR+CA resulted in similar rates of FPE (53% vs. 51%,aOR 1.122, 95%CI[0.745-1.691],p=0.58), mFPE (63% vs. 60.4%,aOR1.250, 95%CI[0.782-2.00],p=0.35), final successful reperfusion (97.6% vs. 98%,p=0.75) and higher chances of successful reperfusion prior to any rescue strategy (81.8% vs. 72.5%,aOR 2.033, 95%CI[1.209-3.419],p=0.007). Functional outcome and safety measures were comparable between both groups. Likewise, the matched analysis (148 patient-pairs) demonstrated comparable results for all clinical and angiographic outcomes except for significantly higher rates of successful reperfusion prior to any rescue strategies with the first-line SR+CA treatment (81.8% vs. 73.6%,aOR 1.881, 95%CI[1.039-3.405],p=0.037). Conclusions Our findings reinforce the findings of ASTER-2 trial in that the first-line thrombectomy with a Combined Technique did not result in increased rates of first-pass reperfusion or better clinical outcomes. However, addition of contact aspiration after initial SR failure might be beneficial in achieving earlier reperfusion.

Older Subjects

Protein supplements are increasingly used by older people to maintain nutrition and prevent or treat loss of muscle function. Daily protein requirements in older people are in the range of 1.2 gm/kg/day or higher. Many older adults do not consume this much protein and are likely to benefit from higher consumption. Protein supplements are probably best taken twice daily, if possible soon after exercise, in doses that achieve protein intakes of 30 gm or more per episode. It is probably not important to give these supplements between meals, as we have shown no suppressive effects of 30 gm whey drinks, and little if any suppression of 70 gm given to older subjects at varying time intervals from meals. Many gastrointestinal mechanisms controlling food intake change with age, but their contributions to changes in responses to protein are not yet well understood. There may be benefits in giving the supplement with rather than between meals, to achieve protein intakes above the effective anabolic threshold with lower supplement doses, and have favourable effects on food-induced blood glucose increases in older people with, or at risk of developing, type 2 diabetes mellitus; combined protein and glucose drinks lower blood glucose compared with glucose alone in older people.

Introduction: Solumbra technique involves the simultaneous use of stent-retriever and large-bore aspiration for clot retrieval in mechanical thrombectomy (MT). We aim to compare various time parameters in patients who undergo MT via solumbra technique via transradial artery (TRA) approach vs. transfemoral artery (TRF) approach. Methods: We performed a retrospective chart review of patients who underwent MT via solumbra technique for anterior circulation large vessel occlusion at a comprehensive stroke center from 7/2014 to 5/2020. We compared time to recanalization parameters, score of TICI≥2b, and functional independence (3-month mRS≤2) in patients who underwent MT via TRA vs.TRF approach via the solumbra technique. A binary logistic regression analysis was performed, controlling for age, sex, pre-treatment-NIHSS, type of anesthesia (general vs.moderate), laterality, and clot location [proximal (internal carotid or M1 segment of the middle cerebral artery) vs.distal (M2 or M3 segment of the middle cerebral artery)]. Results: A total of 98 patients met our inclusion criteria. The mean age was 63.59±14.40 years. 18 (18.37%) patients underwent MT through transradial approach. In our cohort, there was a significant association of TRA with shorter angio suite arrival-time to puncture-time (22.12±9.92mins vs.28.83±12.26mins; OR, 0.94; 95% CI, 0.88-1; P 0.026), but not with puncture-time to recanalization-time (84.34±61.34mins vs.63.73±35.29mins; OR, 1.01; 95% CI, 1-1.03; P 0.085), angio suite arrival-time to recanalization-time (103.12±51.29mins vs.93.42±39.08mins; OR, 1.01; 95% CI, 1-1.02; P 0.524), number of passes to recanalization (1.78±1.36 vs.1.68±1.05; OR, 1.03; 95% CI, 0.66-1.63 ; P 0.899), number of patients with TICI≥2b (83.34% vs.91.25%; OR, 0.68; 95% CI, 0.14-3.4; P 0.633), and functional independence (66.67% vs.78.75%; OR, 0.49; 95% CI, 0.13-1.86; P 0.292), when compared to TRF approach for MT using solumbra technique. Conclusion: Our study demonstrates a significant association between TRA approach with shorter angio suite arrival-time to puncture-time but not with overall time to recanalization, number of patients with TICI≥2b, and functional independence, when compared to TRF approach for MT using solumbra technique.

Introduction: Various scales have been developed to predict long-term clinical outcome after endovascular therapy (EVT) in stroke patients. The objective of this study was to validate and compare five well-validated scales in terms of predictive accuracy for functional independence in a recent endovascular stroke trial (REVASCAT). Hypothesis: We hypothesize that predictive scales (PRE, THRIVE, HIAT2, SPAN-100, FAR) have good-excellent (AUC>0.7) predictive accuracy for good functional outcome and can predict the beneficial effect of EVT demonstrated in randomized clinical trials. Methods: REVASCAT (Randomized Trial of Revascularization with Solitaire-FR Device versus Best Medical Therapy in the Treatment of Acute Stroke Due to Anterior Circulation Large Vessel Occlusion Presenting within Eight Hours of Symptom Onset) enrolled 206 patients who were randomized to receive EVT or best medical treatment. Five scores (PRE-score, THRIVE, HIAT2, SPAN-100 and FAR-score) were retrospectively calculated on patients who received EVT. Receiver-operator characteristics (ROC) for good outcome (mRS 0-2 at 90 days) for each scale were compared. Using the highest predictive scales, the proportion of patients with good outcome by the score categorized in quartiles was analyzed. Results: 103 patients received EVT in the REVASCAT trial (mean age 65.7, median NIHSS 17). Baseline NIHSS, baseline CT-ASPECTS, age and atrial fibrillation, but not previous iv tPA or DM, were associated with good outcome in multivariable analysis. AUC for good outcome was ≥0.70 for FAR (0.74) and PRE (0.70) scores while SPAN-100 (0.67), HIAT2 (0.65) and THRIVE (0.64) had lower AUCs although differences were not statistically significant. The higher the score on the PRE and FAR scores, the lower the proportion of patients with good outcome (PRE-score: 1QT 44.4%, 2QT 24.4%, 3QT 22.2%, 4 QT 8.9%; FAR-score: 1QT 57.8%, 2QT 22.2%, 3QT 6.7%, 4QT 3.3%). Benefit of EVT accordingly to the score on the different scales will be also presented. Conclusions: Of the 5 stroke scales, FAR and PRE had better predictive accuracy for functional independence after EVT. These tools may facilitate decision making for EVT in anterior circulation large vessel occlusion stroke.

Background and Purpose— If anterior circulation large vessel occlusion acute ischemic stroke patients presenting with ASPECTS 0–5 (Alberta Stroke Program Early CT Score) should be treated with mechanical thrombectomy remains unclear. Purpose of this study was to report on the outcome of patients with ASPECTS 0–5 treated with mechanical thrombectomy and to provide data regarding the effect of successful reperfusion on clinical outcomes and safety measures in these patients. Methods— Multicenter, pooled analysis of 7 institutional prospective registries: Bernese-European Registry for Ischemic Stroke Patients Treated Outside Current Guidelines With Neurothrombectomy Devices Using the SOLITAIRE FR With the Intention for Thrombectomy (Clinical Trial Registration—URL: https://www.clinicaltrials.gov . Unique identifier: NCT03496064). Primary outcome was defined as modified Rankin Scale 0–3 at day 90 (favorable outcome). Secondary outcomes included rates of day 90 modified Rankin Scale 0–2 (functional independence), day 90 mortality and occurrence of symptomatic intracerebral hemorrhage. Multivariable logistic regression analyses were performed to assess the association of successful reperfusion with clinical outcomes. Outputs are displayed as adjusted Odds Ratios (aOR) and 95% CI. Results— Two hundred thirty-seven of 2046 patients included in this registry presented with anterior circulation large vessel occlusion and ASPECTS 0–5. In this subgroup, the overall rates of favorable outcome and mortality at day 90 were 40.1% and 40.9%. Achieving successful reperfusion was independently associated with favorable outcome (aOR, 5.534; 95% CI, 2.363–12.961), functional independence (aOR, 5.583; 95% CI, 1.964–15.873), reduced mortality (aOR, 0.180; 95% CI, 0.083–0.390), and lower rates of symptomatic intracerebral hemorrhage (aOR, 0.235; 95% CI, 0.062–0.887). The mortality-reducing effect remained in patients with ASPECTS 0–4 (aOR, 0.167; 95% CI, 0.056–0.499). Sensitivity analyses did not change the primary results. Conclusions— In patients presenting with ASPECTS 0–5, who were treated with mechanical thrombectomy, successful reperfusion was beneficial without increasing the risk of symptomatic intracerebral hemorrhage. Although the results do not allow for general treatment recommendations, formal testing of mechanical thrombectomy versus best medical treatment in these patients in a randomized controlled trial is warranted.
