Filter by:This research delves into the acute prognostic factors influencing functional recovery in individuals who have experienced a stroke. The objective is to describe patterns of functional recovery after a stroke and identify new, clinically significant outcomes or metrics that can serve as predictive indicators for post-stroke functional recovery.
Time is Brain company (http://www.tibtimeisbrain.com/about_us/) developed BraiN20®, a medical device to assess the presence and characteristics of the N20 signal of SEP. Investigators have demonstrated a high prognostic accuracy of N20 on functional recovery of patients with acute ischemic stroke (AIS) due to large vessel occlusion (LVO) undergoing endovascular thrombectomy (EVT), the gold standard treatment. The aim if this new project is to validate BraiN20® in global patients presenting with suspected acute ischemic or hemorrhagic stroke in three comprehensive stroke centers in Spain. The primary objective is to establish the predictive performance of the presence of the N20 SEP over functional recovery as the primary outcome measure (likelihood of having a modified Rankin Scale (mRS) score 0-2 at 3 months evaluated by blinded independent raters). The effect will be measured by the metrics sensitivity, specificity, and predictive values, and compared with clinical and imaging predictive models by Receiving Operating Characteristics (ROC) curve analysis in the global population, stroke subtype and stroke mimics. Secondary aims are: 1) to determine the area under the curve (AUC) of the presence of the N20 SEP as biomarker of functional recovery in small subcortical infarctions and in patients with cortical infarctions and no large vessel occlusion; 2) to characterize N20 SEP signal in hemorrhagic stroke and stroke mimics; and 3) to evaluate the discriminant capacity of an explanatory new algorithm combining pre-hospital clinical variables and N20-SEP signal characteristics between ischemic, hemorrhagic and stroke mimics. This project would represent the first pilot study to validate the ability of BraiN20® to predict the functional recovery in the different types of acute stroke but also its ability to discriminate between stroke subtypes. Thus, BraiN20® monitoring could arise as a paradigm shift in acute stroke management, since it would standardize and accelerate patient triage, enable real time monitoring, increase access to EVT treatment and improve its outcome The trial is sponsored by Time is Brain S.L. and started in March 2024. Primary endpoint results are expected by the end of the 2024. BraiN20® could be a useful medical device aiding stroke subtype diagnosis and functional recovery.
The rescue carotid stenting has recently been an additional treatment followed by mechanical thrombectomy in tandem occlusions of the anterior circulation. Nevertheless, there were few data to date that support this beneficial treatment in Asia. The investigators hypothesized that this treatment related to improvement of clinical outcomes after procedure.
The acute vertebrobasilar occlusion associated with the poor prognosis, particularly tandem occlusion. However, few data on the efficacy of the endovascular therapy was indicated in this occlusion. The investigators reported whether the additional rescue extracranial stenting improved clinical outcome by modified Rankin Scale (mRS) score within 3 months after the procedure
This study aims to evaluate the efficacy of telerehabilitation on stroke patients' capability to perform ADLs after three months of telerehabilitation intervention. Additionally, the investigators also conducted a survey on the satisfaction of patients after telerehabilitation
Motivational interviewing (MI) is a style of communication designed to elicit a person's own reasons for change to drive commitment toward a goal. The goal of this study is to assess the effect of trainee-led MI on patients diagnosed with acute stroke or TIA attributable to modifiable risk factors in comparison to conventional post-stroke counseling, based on patient outcomes, and meaning of work and sense of fulfillment for trainees.
N20 somatosensory evoked potential (SEP) response shows high predictive accuracy of functional recovery in patients with acute ischemic stroke (AIS) undergoing endovascular thrombectomy (EVT). This capacity is independent and even higher than clinical and advanced imaging variables. This study aims to validate BraiN20®, a portable, non-invasive, automatic device to monitor in real-time the presence and characteristics of N20 in AIS patients. 65 patients with AIS and anterior LVO undergoing EVT within 24 hours from onset will be included in three comprehensive stroke centers of Catalonia, Spain. Eligibility criteria are no significant pre-stroke functional dependence, baseline National of Institute of Health Stroke Scale (NIHSS) score equal or higher than 6 points, occlusion (modified Thrombolysis in Cerebral Infarction, (mTICI) 0-1) of the intracranial internal carotid artery (ICA), middle cerebral artery (MCA)-M1 or M2 suitable for EVT per local protocols, without infarct volume restrictions measured by Alberta Stroke Program Early CT (ASPECT) score or by Perfusion Computed Tomography (PCT)/Diffusion Weighted Imaging-Magnetic Resonance Imaging(DWI-MRI) prior to EVT . The primary objective is to confirm an optimal/good reliability of N20 registration before EVT higher than 75% by two blind expert neurophysiologists, assuming a true proportion equal to 87.5%. Secondary endpoints are the predictive accuracy of N20 response recorded by BraiN20® before and after EVT on functional outcome evaluated by the mRS at 7 and 90 days and analyzed by using Receiving Operating Characteristic curves (ROC). A futility interim analysis is planned after the inclusion of 25% population. The trial is sponsored by Time is Brain S.L. and started in September 2023. Primary endpoint results are expected for the first quarter of 2024. BraiN20® could be a useful medical device to predict salvageable brain and functional recovery of patients along the stroke chain.
In the acute posterior circulation strokes, the vertebrobasilar occlusions frequently related to worse outcomes than the anterior ones. However, few studies mentioned the benefit and safety of the emergent stenting in the successful recanalization at these complex occlusions. The investigators investigated whether the improvement of clinical outcome was achieved in postprocedural 3-month.
In acute ischemic stroke due to tandem occlusion, the emergent stenting has recently become an endovascular treatment option combining with mechanical thrombectomy to achieve recanalization. However, the data on the beneficial endovascular management of tandem occlusion in two circulations is still limited. The purpose of our study was to compare the improvement of clinical outcome between two circulations after emergent stenting at 3 months.
