The effectiveness, safety and the long-term success when using the pREset to treat acute occlusions of cerebral vessels will be analyzed. *German: "Gesellschaft mit beschränkter Haftung", limited liability company

Prospective, single-arm, multicenter, observational registry of the ACE Reperfusion Catheters and the Penumbra System in Europe. Consecutive patients presenting within 6 hours from symptom onset with an acute ischemic stroke (within the internal carotid artery and internal carotid terminus, middle cerebral - M1/M2 segments) due to anterior circulation large vessel occlusion (LVO) will be treated using the ADAPT technique with thrombo-aspiration as first intention and site routine practice.

Primary purpose of the trial is to demonstrate the arisen of focal cortical atrophy, localized in the ipsilateral primary motor area, measured in mm, three months after infarction of internal capsule. The patient is compared to himself between day zero to ten and three months. The study hypotheses are: A focal cortical atrophy of the ipsilesional primary motor area occurs after cerebral infarction of the internal capsule. It is measurable accurately and reproducibly by MRI at three months. Other brain areas within the voluntary motor system will also be explored (supplementary motor area, pre motor area). This atrophy is correlated with achievement of pyramidal tract, assessed by the fractional anisotropy of its fibers. This atrophy is correlated with disability at three months, assessed by Rankin score.

Atrial fibrillation (AF) is the most common cause of cardioembolism and a leading cause of ischemic stroke. The diagnosis of AF after cerebral ischemia is difficult to establish even during the treatment at specialised stroke units, as paroxysmal episodes may terminate spontaneously before arrival at the hospital and do not always show early recurrence. However, the diagnosis of AF is of particular clinical relevance since adaequate anticoagulation is one of the most effective secondary preventive treatments in stroke. The detection rate of AF after stroke increases progressively by extending the duration and intensity of cardiac monitoring. For this purpose innovative medical devices and implantable event recorders have been suggested. However, high socioeconomic expenses, malcompliance and the invasiveness of some of these approaches currently limit their use to a minority of affected patients, while the growing number of stroke survivors is lacking access to free and simple screening tools. For primary prevention, the measurement of the peripheral pulse (MPP) is currently the only guideline-recommended screening method among individuals aged 65 years or older. In contrast, MPP has never been applied in the setting of secondary stroke prevention, probably because several factors were expected to interfere with this simple technique, including sensomotor and neuropsychiologic handicaps of stroke patients 18. This study investigates feasibility and validity of MPP in this cohort (pilot phase) and compares daily MPP for 6 months with repeated holter-ECG in patients after ischemic stroke.

Background and hypothesis: The appropriate treatment strategy for secondary stroke prevention in patients with cryptogenic stroke and patent foramen ovale (PFO) remains challenging. Clinical and anatomical variables reported to be risk factors associated with stroke recurrence include older age, large PFO, large right-to-left shunting, and combined atrial septal aneurysm (ASA), which, however, were not confirmed by other studies. The investigators hypothesized that percutaneous closure of PFO could be an effective option for secondary prevention in cryptogenic stroke patients with high-risk PFO. Trial Objective: The primary objective of this study is to assess whether percutaneous device closure of PFO is superior to conventional antithrombotic treatment in preventing stroke recurrence in the cryptogenic stroke patients with high-risk PFO.

The Bernese-European RegistrY for ischemic stroke patients treated Outside current guidelines with Neurothrombectomy Devices using the SOLITAIRE™ FR With the Intention For Thrombectomy (BEYOND-SWIFT) is a retrospective, multi-center, non-randomized observational study aims to investigate the safety and efficacy of a Medtronic market-released neurothrombectomy device (applied as initial devices used for intervention) in acute ischemic stroke patients who do not fulfill treatment eligibility according to current guidelines. Patients will be treated or were treated at the discretion of the investigator, independent of participation in this registry. Primary Analysis is the Impact of successful reperfusion on functional outcome at day 90 in patients presenting with large infarct cores (ASPECTS<6) or minor symptoms (NIHSS<8).

Stroke is a major cerebrovascular disease that causes significant burdens for human health and life, including high morbidity, mortality, and disability. Prolidase enzyme activity was found in various organs, such as the heart, brain, thymus, kidney, lung, pancreas, and spleen, and in plasma, leukocytes, erythrocytes, and dermal fibroblasts. An increase in collagen turnover is known to be correlated with increased prolidase enzyme activity. The aim of this study was to investigate whether SPA levels in AIS patients can be used as a potential diagnostic and prognostic marker. SPA levels were prospectively evaluated in 37 patients aged between 20 and 85 years who were admitted within 24 hours of the onset of AIS. The control group included 37 healthy volunteers of similar age without any disease.

Ischemic stroke occurs when an artery to the brain is blocked. If the artery remains blocked for more than a few minutes, the brain cells may die. This is why immediate medical treatment is critical. Luotai® is the brand name of Panax notoginseng finished product. 2 kinds of formulation are available, the lyophilized powder for Injection and gelatin based soft capsule. They are being used for decreasing incidence of cerebral infarction or ischemic stroke. This study will be conducted as an observational study, regarding the safety, effectiveness of Luotai treatment in acute ischemic stroke patients. This study will be carried out in approximately 360 patients with acute stroke in 6 hospitals in Vietnam - Bạch Mai Hospital, 108 Military Hospital, 103 Military Hospital, Trung Vuong Hospital, Phu Tho General Hospital, 115 Hospital. STUDY PROCEDURES: Participants will be enrolled in an unbiased manner (by consecutive sampling) and consecutive sampling method. The investigators will record participants' information required by the Case Report Form. The study which last for about 3 months, and in each of the visit, the information will be collected includes informed consent, demographic data, ischemic stroke assessment, concomitant medication, adverse reactions. A travel transportation allowance of VND 300,000 will be given for each visit. Participants will receive Luotai and other medications according to the local hospital practice in accordance with the terms of the local marketing authorization in Vietnam. The recommended dosage of Luotai is: Luotai™ injectable lyophilized powder for consecutive 14 days, Luotai soft capsules for 65 days. The participation of the study is fully voluntarily. Patients decide not to participate in the study will not be disadvantaged in any way. All collected information from participants is protected as confidential. The results of the study may be published in medical literature, but participants will not be identified. This study does not include any procedure/test that there were not indicated according to local clinical practice. There is no specific associated risks or discomforts in this study related to the participation. The results of this research may guide in further understanding the Ischemic Stroke.

This study is a prospective, open-label, multi-center, registry study, designed to show that rescue stenting is safe and effective for emergency large vessel occlusion (ELVO) patients who have mechanical thrombectomy failure. Participants with ELVO will initially underwent mechanical thrombectomy usig stent retriever, contact aspiration or both. After failure of mechanical thrombectomy, rescue stenting will be performed.

The purpose of this study is to compare the risk of cardiovascular events associated with the use of sodium-glucose cotransporter 2 (SGLT2) inhibitors in comparison with the use of dipeptidyl peptidase-4 (DPP-4) inhibitors among patients with type 2 diabetes. The investigators will carry out separate population-based cohort studies using health care databases in seven Canadian provinces and the United Kingdom. The study cohort will be defined by the initiation of a SGLT2 inhibitor or a DPP-4 inhibitor after SGLT2 inhibitors entered the market. Patients will be followed up until the occurrence of a cardiovascular event. The results from the separate sites will be combined by meta-analysis to provide an overall assessment of the risk of cardiovascular events in users of SGLT2 inhibitors. The investigators hypothesize that the use of SGLT2 inhibitors will be associated with a decreased risk of cardiovascular events in comparison with the use of DPP-4 inhibitors.
