Filter by:In recent years, mobile health (mHealth) apps have promised improved monitoring of health conditions to improve clinical outcomes. The objective of this study is to conduct a pilot randomized clinical trial (RCT) to evaluate the impact of using remotely collected patient generated health data (PGHD) from older patients undergoing bypass surgery due to chronic limb threatening ischemia. The hypothesis is that integrating PGHD with an EHR system will help providers manage post-surgical symptoms and thus improve post-operative mobility and quality of life health outcomes.
Affecting more than 150,000 patients in France, stroke is a major public health issue and a leading cause of disability worldwide. In western countries, 80-85% of strokes are of ischemic subtype. This study will focus on young adults, aged 18-45, with a diagnosis of ischemic stroke. Studies assessing post-stroke cognition in young patients reported an alarming prevalence of cognitive impairment, affecting about 60% of stroke survivors between 4 and 12 months after the acute event. However, longitudinal data on neurocognitive trajectories (i.e., the evolution of cognitive impairment over time) in young patients with ischemic stroke are lacking. Collecting such data requires an exhaustive neuropsychological assessment and several functional evaluations, at different times, for the same patient. Repeated neurocognitive study of young patients with ischemic stroke will enable: a description of the prevalence of impaired global cognitive efficiency, an analysis of the specific neurocognitive domains affected, and the tracing of trajectories of recovery from cognitive impairment over time, in terms of global cognitive efficiency and as a function of specific neurocognitive domains (memory, executive, attentional, social cognition, instrumental functions, fatigability, etc.). Up to date, the clinic-radiological predictors and associated factors of neurocognitive impairment after ischemic stroke in young patients have not been studied. Ischemic stroke causes acute brain lesions of the gray matter (GM) and white matter (WM). Numerous studies suggest that cognitive health may be more closely linked to the integrity of WM than to GM. Magnetic resonance imaging (MRI), and in particular diffusion tensor imaging (DTI) sequences, analyze WM bundles. By using fiber tracking algorithms image analysis enable the WM fiber bundle reconstruction and allow quantifying the volume of lesions (pre-existing and ischemic stroke-induced) in the WM tract. The aim of this study is to study whether the extension of pre-existing and acute white matter lesions is associated with poorer cognitive recovery after ischemic stroke, both in terms of global cognitive performance and impairment in specific neurocognitive domains.
The study is a prospective multicentre registry study. Patients admitted to 10 stroke centres nationwide from September 2022 to September 2025 with acute ischaemic stroke due to large vessel occlusion considering underlying ICAS and treated with emergency endovascular thrombolysis were included for analysis. Patients who met the general inclusion criteria underwent thrombectomy and the necessary remedial treatment.
The ENIGMA study is a single-centre prospective clinical observational study with the aim to investigate vascular contributions to cognitive decline and dementia. By studying MRI-defined capillary dysfunction and EV profiles, the ENIGMA study links novel imaging and basic research techniques to a clinical cohort of stroke patients. With this study we hope to enhance the understanding of the mechanisms behind post-stroke cognitive decline and dementia.
In this study, a multicenter, randomized, controlled, prospective cohort study was conducted to observe the effect of Edaravone Dexborneol on the incidence and outcome of bleeding transformation after thrombolysis in acute ischemic stroke. To explore the methods to reduce the dilemma of bleeding transformation after thrombolysis, and to dynamically detect the changes of the main links causing bleeding transformation such as blood-brain barrier damage, local immune response activation and so on. To explore the mechanism of Edaravone Dexborneol in reducing bleeding transformation. It is proved that Edaravone Dexborneol combined with thrombolytic therapy can reduce the risk of bleeding and transformation after thrombolysis and improve the safety of thrombolysis. Secondly, it can improve the early recanalization rate of ischemic stroke patients after thrombolytic therapy, and effectively protect the integrity of the blood-brain barrier.
Along with the current clinical trial, the efficacy and safety of a 300 mg loading dose of ticagrelor administered within 24 hours of the first-ever large-vessel ischemic stroke compared to 200 mg cilostazol were assessed through NIHSS, mRS, and possible adverse effects.
Along with the current clinical trial, the efficacy and safety of a 300 mg loading dose of ticagrelor administered within 24 hours of the first-ever moderate to severe ischemic stroke compared to 200 mg cilostazol were assessed through NIHSS, mRS, and possible adverse effects.
(1) The main purpose To explore the predictive value of human microbiome and its metabolome for adverse prognosis in patients with acute ischemic stroke (AIS). (2) Secondary purposes 1. To explore the characteristics of cross-regional disturbance of human microbiome in stroke patients; 2. To investigate the characteristics and rules of bacterial flora changes before and after recurrent apoplexy; 3. Markers closely related to AIS prognosis and cognitive emotional complications were excavated by metagenomic, metabolic, peptide and imaging groups. 4. To explore the relationship between serum markers of ultra early stage and prognosis.
The goal of this prospective randomized controlled clinical trail is to explore the value of integrating continuous cardiac index variability indicators with existing weaning standards to guide perioperative myocardial injury patients weaning. The main question it aims to answer is: whether the introduction of new indicators for weaning standards can improve the success rate of weaning. Treatment that'll be given to participants is: the cardiac index (CI) is continuously monitored from 15-30 minutes prior to the start of the weaning from ventilation. Participants who increase their CI by more than 30% can have their tracheal intubation removed. Researchers will compare the weaning success rate of CI group and control group.
Tocilizumab may exert neuroprotective effects in patients with ischemic stroke undergoing endovascular treatment
