Filter by:The goal of this observational, practice-based feasibility study is to observe the efficacy and safety of intramuscular administration of Stempeucel® in Malaysian patients with critical limb ischemia (CLI) due to Buerger's disease. The main questions it aims to answer are: - Can intramuscular administration of Stempeucel® reduce symptoms of CLI due to Buerger's disease while improving the healing rate and functional outcomes? - Does intramuscular administration of Stempeucel® causes any serious adverse events in CLI due to Buerger's disease patients? Study patients will be assessed by the PI before administering the Stempeucel® for any other organ with inflammation. The study patients will also be followed up to the duration of 1 year after study treatment administration for safety and efficacy assessment.
A prospective, multicenter and cluster randomised controlled trial will be conducted, using hospital as randomisation unit. Hospitals in Zhejiang Province, China, will be randomised into two arms (1:1): an intervention arm and a control arm. Hospitals in the intervention arm will receive a multilevel system intervention based on information platform, whereas hospitals in the control arm will receive no intervention. The randomisation will be conducted after baseline data collection. The following baseline data will be used for randomisation match: hospital classification, beds in stroke centre, and the number of acute ischemic stroke (AIS) patients within 7 days of stroke onset. Hospitals with <250 AIS cases per year will be excluded from the study. The primary outcome will be difference between intervention arm and control arm in the one-year stroke recurrence rate on the follow-up stage (post-intervention).
RESTORE is a randomized clinical trial investigating the safety and feasibility of using EEG treatment targets (burst suppression vs. seizure suppression) for post-cardiac arrest refractory status epilepticus treatment.
This study is to evaluated the safety and efficacy of BMSCs transplantation in the treatment of ischemic stroke, so as to provide a basis for future clinical application of BMSCs transplantation in the treatment of ischemic stroke.
Recent years have witnessed a change in the therapeutic paradigm of stroke with the advent of mechanical thrombectomy as the reference treatment. However, despite the achievement of effective proximal recanalization in nearly 80% of patients, nearly half of these patients have an unfavorable functional outcome. Several causes can be mentioned, such as the extent of the initial ischemic damage, the occurrence of complications related to reperfusion treatments or the occurrence of thrombosis of the downstream microvascularization. The latter is a phenomenon that has been known and studied increasingly over the last twenty years. It is the result of multiple cellular remodeling following ischemia and at the origin of an endoluminal filling by platelets, inflammatory cells and fibrin. This phenomenon introduces the fundamental difference between recanalization, i.e. the removal of the obstruction by the thrombus, and reperfusion, which translates into a satisfactory supply of oxygen to the ischemic tissues and therefore the expected result of these treatments. However, not all recanalization is necessarily accompanied by reperfusion, which is the phenomenon of no-reflow. This last situation could be explained by downstream microvascular thrombosis. Studies have shown the interest of intravenous thrombolysis associated with mechanical thrombectomy to preserve this vascular bed and improve cerebral reperfusion. More recently, a study has also shown the value of adding intra-arterial thrombolysis after mechanical thrombectomy. Nevertheless, there is currently no clinical evidence of the reality and prognostic importance of downstream microvascular thrombosis. Advances in imaging have allowed the development of susceptibility weighted imaging (SWI) sequences with millimeter resolution, allowing a precise study of vascular damage and the appearance of previously unseen remodeling. Among them, the existence of cortical or juxta-cortical microinfarcts whose remnographic characteristics differed by the presence of a SWI hyposignal. The hypothesis evoked is that of a hemorrhagic remodeling consecutive to the barrier rupture. However, in view of the pathophysiology explained so far and the hypointense character of the thrombi on the SWI sequences, these remodeling could in fact be not microbleeding but rather markers of thrombosis in the downstream microcirculation. MRI would allow to identify the presence and the importance of microvascular thrombosis and thus to bring arguments to specifically target this microvascular component, consequence of cerebral ischemia, by antithrombotic or thrombolytic treatments. The objective of our project is therefore to carry out a study focused on a better description and understanding of cortical and basal ganglia SWI hyposignals with a histopathological correlation and with the clinical prognosis.
Although older studies, most of them retrospective in design, advocated sedation over general anesthesia during endovascular treatment for acute ischemic stroke, a recent meta-analysis and randomized studies have shown that general anesthesia is associated with better functional status at 3 months compared with local anesthesia and sedation. In our center, most procedures are performed under general anesthesia, and once the procedure is complete, the patient is transferred intubated and sedated to the ICU. If the patient is hemodynamically and respiratory stable, the patient will be extubated, and will be discharged to the Neurology hospitalization floor. Several factors have been described that may influence the evolution and functional status at three months of patients who have suffered a stroke and have received endovascular treatment, such as the time between the onset of symptoms and admission to the ward for performing the procedure, the use of general anesthesia compared to sedation and local anesthesia, adequate control of blood pressure, the size of the cerebral infarct, or a worse neurological examination at the time of the procedure. In turn, several factors have been described that may influence the success of extubation in a patient who has suffered an acute ischemic stroke and who has required orotracheal intubation, such as the absence of dysarthria, the size of the infarct, the location of the infarction, the NIHSS (National Institutes of health Stroke Scale) or neurological status prior to orotracheal intubation. The investigators do not know, however, whether the time of mechanical ventilation can influence the evolution and functional status at three months of patients who have suffered a stroke and have received endovascular treatment under general anesthesia
Prospective, randomised, open-label, international multicenter trial to evaluate the safety and efficacy of drug-coated balloon (DCB) treatment compared to drug-eluting stenting (DES) in patients with large coronary artery disease.
Stress is highly prevalent in patients with ischemic heart disease (IHD) and is associated with lower health-related quality of life and worsened cardiovascular outcome. The importance of stress management is now recognized in recent cardiovascular guidelines. However, effective stress management intervention are not implemented in clinical routine yet. The development of easily disseminated eHealth interventions, particularly mHealth, may offer a cost-effective and scalable solution to this problem. The aim of the proposed trial is to assess the efficiency and cost-effectiveness of the mHealth intervention 'mindfulHeart' in terms of reducing stress in patients with IHD.
Ischemic cerebrovascular disease will cause serious harm to the life and safety of patients, and the treatment prognosis is poor. Numerous clinical trials have demonstrated that probiotics can improve cognitive function in people under multimodal. We have previously found that Lactobacillus acidophilus administration could improve cognitive impairment in MCAO and BCAS mice. Therefore, Based on the above research background and the basis of previous studies, we believe that the administration of Lactobacillus acidophilus solid drink (pure Lactobacillus acidophilus strain) can improve the cognitive function of patients with cerebral ischemia through the "brain-gut axis".
The current multi-center study aims to evaluate the efficacy and safety of pBFS-guided rTMS Neuromodulation Treatment for the rehabilitation of language functions in ischemic stroke aphasic patients.
