Obesity-stroke paradox and initial neurological severity
Conclusions In our study, although obesity was associated with better short-term functional outcomes, INS might be a more important prognostic factor. Therefore, initial status should also be considered when considering an ‘obesity paradox’ in chronic diseases.

M1 is not M1 in ischemic stroke: the disability-free survival after mechanical thrombectomy differs significantly between proximal and distal occlusions of the middle cerebral artery M1 segment
Conclusions Proximal occlusions of the M1 segment of the MCA incorporating the lenticulostriate perforators are associated with a poorer clinical outcome than distal M1 occlusions that spare these perforators. Involvement of these perforators might become an additional predictor of clinical outcome after mechanical thrombectomy in ischemic stroke.

Aneurysm location and clipping versus coiling for development of secondary normal-pressure hydrocephalus after aneurysmal subarachnoid hemorrhage: Japanese Stroke DataBank.
CONCLUSIONS Patients with low-grade SAH caused by a ruptured MCA aneurysm had a low risk for the development of sNPH. In contrast, patients with high-grade SAH caused by a ruptured ACA aneurysm had a higher risk for sNPH. Endovascular coiling might confer a lower risk of developing sNPH than microsurgical clipping.

Multicenter clinical experience in over 125 patients with the Penumbra Separator 3D for mechanical thrombectomy in acute ischemic stroke
Conclusions The results suggest that the Separator 3D enables safe and effective revascularization of occluded large arteries in acute stroke intervention, leading to a high rate of functional independence at 90 days.

Direct aspiration first pass technique for the treatment of acute ischemic stroke: initial experience at a European stroke center
Conclusions The direct aspiration first pass technique proofed to be fast, effective, and safe. Promising revascularization results can be achieved quickly in more than 50% of patients using this technique as the firstline option. Nevertheless, stent retrievers are still warranted in approximately 40% of cases to achieve a favorable revascularization result.

Transcranial direct current stimulation facilitates motor learning post-stroke: a systematic review and meta-analysis
Transcranial direct current stimulation (tDCS) is an attractive protocol for stroke motor recovery. The current systematic review and meta-analysis investigated the effects of tDCS on motor learning post-stroke. Specifically, we determined long-term learning effects by examining motor improvements from baseline to at least 5 days after tDCS intervention and motor practise. 17 studies reported long-term retention testing (mean retention interval=43.8 days; SD=56.6 days) and qualified for inclusion in our meta-analysis. Assessing primary outcome measures for groups that received tDCS and motor practise versus ...

Enrollment bias: frequency and impact on patient selection in endovascular stroke trials
Conclusions The majority of patients felt suitable for EST at our institution were excluded from recent trials. Formal entry criteria succeeded in selecting patients with better prognostic features, although many of these patients were treated outside of trials. Acknowledging and mitigating these biases will be crucial to ongoing investigations.

The 'pit-crew model for improving door-to-needle times in endovascular stroke therapy: a Six-Sigma project

Measuring arm function early after stroke: is the DASH good enough?
Conclusions RMT methods identified limitations missed by CTT and indicate areas for improvement of the DASH as an upper limb measure for acute stroke. Findings, similar to those identified in multiple sclerosis, highlight the need for scales to have strong conceptual underpinnings, with their development and modification guided by sophisticated psychometric methods.

Feasibility of combined surgical and endovascular carotid access for interventional treatment of ischemic stroke
Conclusions Surgical carotid access for endovascular stroke treatment is feasible, with considerable advantages, in patients with expected problematic access or for whom transfemoral endovascular carotid access has failed.

Anesthetic variation and potential impact of anesthetics used during endovascular management of acute ischemic stroke
Conclusions Our data support the notion that anesthetic techniques and associated physiology used in EMAIS are not homogeneous, making any statements about the effects of generic GA in stroke ambiguous. Moreover, our data suggest that the type of GA may affect the outcome after EMAIS.

Revisiting the NIH Stroke Scale as a screening tool for proximal vessel occlusion: can advanced imaging be targeted in acute stroke?
Conclusions In this cohort, specific NIHSS criteria were highly sensitive for emergent large vessel occlusion and, if validated, may allow for clinical screening prior to advanced imaging with CT angiography.

Risk of acute kidney injury associated with neuroimaging obtained during triage and treatment of patients with acute ischemic stroke symptoms
Conclusions This study provides preliminary evidence of the safety and feasibility of obtaining CTSS with additional DSA imaging, whether for diagnosis or intervention, to identify possible acute ischemic stroke.

Impact of immediate post-reperfusion cooling on outcome in patients with acute stroke and substantial ischemic changes
Conclusions The use of post-reperfusion cooling as a rescue treatment in patients with substantial ischemia at baseline might improve clinical outcome.

Comparison of outcome and interventional complication rate in patients with acute stroke treated with mechanical thrombectomy with and without bridging thrombolysis
Conclusions Preceding use of IVT was not an independent predictor of favorable outcome in patients with acute stroke treated with MT and complication rates did not differ whether or not IVT was used. MT is safe and achieved a favorable outcome in one-third of patients with stroke ineligible for IVT.
