Filter by:Transient Ischaemic Attack (TIA), also called 'ministroke' is characterised by shortlasting symptoms that generally do not cause permanent damage. 'Minor stroke' is a term used to describe a stroke with mild and nondisabling symptoms. TIA and minor stroke patients account for more than half of all cases of stroke and they are at a higher risk to suffer a major stroke. Currently, management of TIA/minor stroke patients is mainly focused on identifying and reducing risk factors for a later stroke. However, people after a TIA often have limited access for further specialist support from stroke-specific rehabilitation services. Although there is variability in the level of recovery and severity of symptoms after TIA and minor stroke, there is evidence that these patients may experience difficulties that affect their quality of life including anxiety and depression. This study aims to develop, tailor and target the delivery of a time-limited group intervention that offers educational, psychological and social support for people following TIA and minor stroke. A qualitative study (Phase 1) will be conducted with service users and experts working with people with TIA/minor stroke to develop the psychoeducational intervention. Following this, we will conduct a feasibility randomised controlled trial in one centre (Phase 2) to explore whether this group psychoeducational intervention for people after TIA and minor stroke carers is acceptable and to determine the feasibility of the proposed evaluation and the sample size needed in a definite trial.
Investigators will study whether immediate statin treatment after the onset of stroke is beneficial on the neurological protection
This study will validate the sensitivity of a purine biosensor (SMARTChip) in detecting acute cerebral ischaemia in a group of patients undergoing elective carotid endarterectomy. The study will also investigate whether blood purine levels are indicative of future risk of stroke by comparing pre-operative blood purine levels in carotid endarterectomy patients (high risk group) and blood purine levels in a group of age and sex-matched controls.
This study will try to evaluate the effectiveness and safety of a new method for achieving mild hypothermia, i.e.,mild hypothermia therapy through rectum. Half of participants will be treated by the widely-used hyper-hypothermia blanket method, while the other half will be treated by the investigators' new method.
The aim of this observational study is to evaluate the outcomes and safety of the Paclitaxel-eluted balloon catheter ELUTAX SV for treatment of peripheral arterial disease (PAD) in below-the-knee vessels
The researchers aim to investigate the effect of memantine on stroke outcome in a randomized double-blind placebo-controlled clinical trial.
The goal of this proposal is to profile the pharmacokinetics of dexmedetomidine in newborns ≥36 weeks post-menstrual age during therapeutic hypothermia for hypoxic-ischemic encephalopathy.
The aim of this study is to evaluate the safety and effectivity of Ginkgo diterpene lactone meglumine injection tn the treatment of acute ischemic stroke
Mechanical thrombectomy (TM) is now validated through 4 randomized controlled trials of high scientific level as the reference treatment of cerebral infarction associated with proximal cerebral occlusion (MR CLEAN, ESCAPE 2014, 2015). These studies have shown for the first time a major decrease (-35%) of disability related to severe cerebral infarction and reduction in mortality. These studies only used thrombectomy devices called stent retriever for obtaining recanalization rates ranging from 58-72% for the 2 largest studies (MR CLEAN, ESCAPE 2014, 2015). This criterion "recanalization" is important because it largely determines the functional prognosis of patients with severe cerebral infarction (Khatri, 2014). These results are exciting but we can do even better. Indeed, already new thrombectomy devices are available with a special interest for ADAPT (A Direct Aspiration First Pass Technic). This distal suction system, with a high level of endovascular navigability, provides high recanalization rates (> 90%), low morbidity, with a synergistic effect with stent retriever (Turk A, Kowoll 2014 and 2015). To date, these technic (ADAPT) has never been assessed in a randomized controlled trial. We have previously conducted a comparative observational study between two recanalization strategies by thrombectomy using first-line ADAPT or the most widely used stent retriever. The interventional neuroradiologist could, in case of recanalization failure with the Solitaire system, used another thrombectomy material left to the operator's choice. 244 consecutive patients on two centers (Rothschild Foundation, and Foch Hospital, France) admitted for a cerebral infarction associated with proximal occlusion were included. This is so far the largest series of patients with ADAPT system. The complete recanalization rate was 84% with ADAPT versus 68% with stent retriever (P = 0.006). Unpublished data, Oral presentation at the European Stroke Organization, April 2015). Our research aims to show that a first line strategy of recanalization by thrombectomy using a distal suction system (ADAPT) is superior that the use of a stent retriever.
The rise in life expectancy implies an increased number of nonagenarian patients who need evaluation for critical lower limb ischaemia (CLI). The study goal is to evaluate whether revascularization techniques in these patients fulfill a set of security and efficacy criteria generated from surgical results in a validated historical cohort.
