ObjectiveTo investigate in routine care the efficacy and safety of IV thrombolysis (IVT) with tenecteplase prior to mechanical thrombectomy (MT) in patients with large vessel occlusion acute ischemic strokes (LVO-AIS), either secondarily transferred after IVT or directly admitted to a comprehensive stroke center (CSC).MethodsWe retrospectively analyzed clinical and procedural data of patients treated with 0.25 mg/kg tenecteplase within 270 minutes of LVO-AIS who underwent a brain angiography. The main outcome was 3-month functional independence (modified Rankin scale score ≤ 2). Recanalization (revised Treatment in Cerebral Ischemia score 2b-3), was evaluated before (pre-MT) and after MT (final).ResultsWe included 588 patients (median age 75 years [interquartile range (IQR) 61-84]; 315 women [54%]; median NIH Stroke Scale [NIHSS] score 16 [IQR 10-20]), of which 520 (88%) were secondarily transferred after IVT. Functional independence occurred in 47% (n = 269/570; 95%CI 43.0-51.4) of patients. Pre-MT recanalization occurred in 120 patients (20.4%; 95%CI 17.2-23.9), at a similar rate across treatment paradigms (direct admission, n = 14/68 [20.6%]; secondary transfer, n = 106/520 [20.4%]; p > .99) despite a shorter median IVT-to-puncture time in directly admitted patients (38 [IQR 23-55] vs 86 [IQR 70-110] minutes; p < .001). Final recanalization was achieved in 492 patients (83.7%; 95%CI 80.4-86.6). Symptomatic intracerebral hemorrhage occurred in 2.5% of patients (n = 14/567; 95%CI 1.4-4.1).ConclusionsTenecteplase before MT is safe, effective and achieves a fast recanalization in everyday practice in patients secondarily transferred or directly admitted to a CSC, in line with published results. These findings should encourage its wider use in bridging therapy.Classification of EvidenceThis study provides class IV evidence that tenecteplase within 270 minutes of LVO-AIS is increases the probability of functional independence.

We demonstrated longer pre-hospital delays and higher in-hospital mortality in women. The increase in the time to treatment alone does not completely explain the persistent increase in mortality. Further studies, public awareness programmes and physician education are necessary to reduce delays and improve the prognosis of STEMI in women.

BackgroundWhen exploring changes in upper limb kinematics and motor impairment associated with motor recovery in subacute post stroke during intensive therapies involving robot-assisted training, it is not known whether trained joints improve before non-trained joints and whether target reaching capacity improves before movement accuracy.MethodsTwenty-two subacute stroke patients (mean delay post-stroke at program onset 63 ± 29 days, M2) underwent 50 ± 17 (mean ± SD) 45-min sessions of robot-assisted (InMotion™) shoulder/elbow training over 3 months, in addition to conventional occupational therapy. Monthly evaluations (M2 to M5) included Fugl-Meyer Assessment (FM), with subscores per joint, and four robot-based kinematic measures: mean target distance covered, mean velocity, direction accuracy (inverse of root mean square error from straight line) and movement smoothness (inverse of mean number of zero-crossings in the velocity profile). We assessed delays to reach statistically significant improvement for each outcome measure.ResultsAt M5, all clinical and kinematic parameters had markedly improved: Fugl-Meyer, +65% (median); distance covered, +87%; mean velocity, +101%; accuracy, +134%; and smoothness, +96%. Delays to reach statistical significance were M3 for the shoulder/elbow Fugl-Meyer subscore (+43%), M4 for the hand (+80%) and M5 for the wrist (+133%) subscores. For kinematic parameters, delays to significant improvements were M3 for distance (+68%), velocity (+65%) and smoothness (+50%), and M5 for accuracy (+134%).ConclusionsAn intensive rehabilitation program combining robot-assisted shoulder/elbow training and conventional occupational therapy was associated with improvement in shoulder and elbow movements first, which suggests focal behavior-related brain plasticity. Findings also suggested that recovery of movement quantity related parameters (range of motion, velocity and smoothness) might precede that of movement quality (accuracy).Trial registrationEudraCT 2016–005121-36.
