Filter by:The goal of this observational study is to compare pulmonary health parameter measurements from the VQm PHM™ to existing clinical measurements. The main questions it aims to answer are: - Confirm the performance of non-invasive pulmonary health parameter shunt fraction value found on the VQm PHM™ when compared to available reference measurements. - Confirm the performance of non-invasive pulmonary health parameter pulmonary blood flow, functional residual capacity and physiological dead space found on the VQm PHM™ when compared to available reference measurements.
The primary objective of this clinical study is to assess the comparative efficacy of individualized intermittent theta burst stimulation (iTBS) in contrast to standard iTBS for individuals post-stroke experiencing upper limb impairment. The key inquiries addressed in this study encompass: Enhancement of Upper Limb Function: The primary investigation seeks to determine whether individualized iTBS yields superior improvements in upper limb functionality compared to standard iTBS. Long-Term Effects: This study endeavors to explore the sustained effects of both individualized and standard iTBS on upper limb function over an extended duration. Neural Mechanisms Investigation: Functional near-infrared spectroscopy (fNIRS) will be employed to elucidate the neural mechanisms underlying the impact of iTBS on the enhancement of upper limb function. Post-stroke individuals with upper limb impairment will undergo pre-treatment assessments, including motor function evaluations and fNIRS tests. Subsequently, they will be randomized into three groups: individualized iTBS, standard iTBS, and sham stimulation. Participants will undergo post-treatment assessments and follow-up evaluations. The research team aims to discern disparities in the efficacy of different iTBS modalities. The central hypothesis posits that individualized iTBS will demonstrate superior efficacy in enhancing post-stroke upper limb function, with sustained effects persisting for a minimum of one month.
To investigate the therapeutic effect of including virtual reality-based digital content in the upper limb motor function rehabilitation of stroke patients and to develop a treatment method to improve the upper limb motor function of stroke patients in the future.
Stroke volume variation (SVV) is an indicator used to assess the patient's volume status. The FloTrac system (Edwards Lifesciences, Irvine, CA) continuously monitors cardiac output (CO) and SVV (SVV-FloTrac) by analyzing the systemic arterial pressure wave. Numerous studies have demonstrated that SVV-FloTrac serves as a reliable indicator of fluid responsiveness. However, its peripheral invasiveness raises concerns about susceptibility to reflecting waves, damping, and vascular tone influences.In contrast, Transthoracic electrical bioimpedance (BioZ.com™) offers a non-invasive approach for continuously monitoring various hemodynamic variables. In this study, the primary aim was to assess the agreement between simultaneously measured SVV-FloTrac and SVV-BioZ.
The purpose of this study is to determine the effect of ginkgo biloba extract on cognitive function in acute ischemic stroke.
This study aims to evaluate the efficacy of Y-6 sublingual tablets in improving microcirculation dysfunction and reducing thrombo-inflammation in patients who had AIS caused by LVO and received reperfusion therapy. Moreover, we expect to evaluate the safety of using Y-6 sublingual tablet in such study population.
The purpose of this study is to evaluate the safety and efficacy of urinary kallidinogenase treatment in patients with large artery atherosclerotic acute ischemic stroke.
This is a prospective cohort study to investigate the early impact of evolocumab on patients with acute ischemic stroke (AIS) in China. Evolocumab, a proprotein convertase subtilisin/kexin taye 9 inhibitor, can significantly reduce low density lipoprotein cholesterol (LDL-C) levels and has a positive effect on improving cardiovascular events. However, existing studies have focused almost exclusively on the long-term effects of Evolocumab, and the early effects of Evolocumab on AIS patients remains unclear.
To assess the efficacy and safety of tirofiban administration after intravenous thrombolysis for patients with AIS.
The primary purpose of this trial is to evaluate the effects of Human Urinary Kallidinogenase on improvement of neurological outcome, and early cerebral perfusion in acute ischemic stroke.
