Filter by:In this proposal, the investigators will demonstrate the feasibility and noninferiority of telerobotic ultrasonography as compared to traditional manual acquisition in performing a limited carotid Duplex examination and in carotid plaque detection.
The goal of this [type of study: exercise intervention study] is to test in describe participant health conditions. The main questions it aims to answer are: - [Whether physical exercise improves executive function of male heroin addicts] - [Whether physical exercise improves negative thinking/affect psychological experience of male heroin addicts] Participants will be randomly selected for medium-intensity strength training (resistance exercise,n=30), 30 will be selected for 1-hour long balloon volleyball sessions (aerobic exercise) at 60-70% volume of oxygen uptake during peak exercise, weekly 5 times for 12 weeks; and 30 will be assigned to the no-exercise control group, Participants will perform Executive function tests and the Symptom Checklist-90 Revised questionnaire at pre and post intervention. Researchers will compare resistance exercise group,aerobic exercise group and no-exercise control group to see if effects of exercise on executive function and negative thinking/affect psychological experience of male heroin addicts.
Based on clinical manifestations, laboratory data and intestinal microflora detection, the cognitive function characteristics of patients with systemic lupus erythematosus and cerebrovascular disease and its relationship with intestinal microflora were analyzed to explore the possible pathogenesis of lupus cerebrovascular disease.

Obstructive Sleep apnea(OSA) is a disease with multiple causes, and treatments are very diverse. Patients and doctors have a lot of choices. The concept of precision medicine is needed to intervene so that doctors and patients can have directions in this huge map and won't get lost. In this OSA maze, we have already walked through some feasible passages, but we are far from reaching the end. At present, the research direction of artificial intelligence for OSA is mostly focused on how to accurately screen, but less attention is paid on how to accurately treat and conveniently follow the effectiveness of treatment to increase patient compliance. We can already analyze the results of electrocardiogram patches to predict the severity of sleep apnea. We have also been able to analyze the results of electrocardiogram patches for three consecutive nights, and found postural sleep apnea that could not be detected in laboratory sleep examinations, and help doctors provide appropriate intervention to improve patients' sleep apnea, severity and quality of sleep. We have also found that precision sleep endoscopy can be used to predict the outcome of sleep apnea patients after surgery and the effectiveness of treatment with an intraoral nagative airway pressure device. Therefore, in the future, with artificial intelligence(AI), ECG patches are able to be used for follow patients' treatment effectiveness. Others include the treatment of weight loss drugs and bariatric surgery for obese patients, the control of environmental temperature and humidity, and the training of oropharyngeal and tongue muscle strength, all of which require the diagnosis and follow up of AI ECG patches from beginning to end. According to the latest research, nocturnal hypertension is more relevant to the prognosis of cardiovascular problems and cerebrovascular disease that may occur in the future. This is also the problem that we are most concerned about in the treatment of sleep apnea. ECG patches also have the potential to provide us with information about nocturnal hypertension. Studies have also shown that ECG patches test results are highly correlated with nocturnal hypertension. Therefore, the improvement of nocturnal hypertension can also be used as an important indicator of the effectiveness for our treatment of sleep apnea. Therefore, the goal of this project is to develop AI algorithm to make ECG patches more helpful to patients with sleep apnea, and to make better treatment decisions that are most suitable for patients, such as postural therapy, bariatric surgery for obese patients, environmental temperature and humidity control, oropharyngeal tongue muscle strength training, and accompany with sleep endoscope for the selection of intraoral negative pressure devices and surgery, and finally use AI ECG patches for the patient for three consecutive nights to evaluate the improvement of nocturnal hypertension and sleep apnea, and to achieve the goal of precision medicine in OSA.
This study is aimed to investigate the changes in pharmacokinetics and efficacy of antiplatelet agents before and after distal gastrectomy in gastric cancer patients taking oral antiplatelet agents for primary or secondary treatment for cardiovascular disease and to evaluate its impact on the occurrence of postoperative bleeding complications and thromboembolic events.
To determine the effect of capsaicin upon serial transcranial Doppler (TCD) markers of cerebral blood flow (CBF). Methods Serial TCD testing in 30 participants with cerebrovascular risk factors. Capsaicin doses .66 and .99 μMol. Outcomes: peak systolic and end-diastolic velocities in the middle cerebral artery (MCA), mean velocity (MV), pulsatility index (PI), CBF index, arterial pressure, and perceived pungency (PP) in five minutes intervals up to 20 minutes.
The aims of this proposal are to: 1) investigate whether individuals with spinal cord injury (SCI) demonstrate cardiac autonomic, cerebrovascular, and cognitive dysfunctions compared to non-injured age- and sex-matched controls in the following conditions: supine rest and head-up tilt/face-cooling test; 2) examine if autonomic completeness/ incompleteness, physical activity, and psychological distress are predictors for dysfunctions during supine rest and head-up tilt/face cooling conditions in SCI individuals; 3) examine if one bout of moderate-intensity aerobic exercise temporarily improves cardiac autonomic and cerebrovascular functions and thereby improves cognition when in supine rest and head- up tilt/face cooling conditions. The study will include an initial visit and an experimental visit to our lab. Three groups of participants will be included in this study: Group 1, SCI with acute exercise; group 2, SCI with rest-control; and group 3, age- and sex-matched non-injured individuals. Cardiovascular variables, such as heart rate variability, blood pressure variability, and cerebrovascular variables, such as cerebral blood flow velocity and oxygenated hemoglobin, and cognitive performance will be examined. The investigator hypothesizes that individuals with SCI will have impaired cardiac autonomic, cerebrovascular, and cognitive functions compared to the non-injured controls, and an acute exercise can improve those functions. Autonomic completeness/incompleteness, physical activity, and psychological distress are significant factors that predict cardiac autonomic, cerebrovascular, and cognitive functions in individuals with SCI.
The majority (>80%) of strokes are of ischemic etiology, of which ≈15% to 20% are attributable to atherosclerosis of the extracranial carotid arteries. The primary goal in carotid artery revascularization is to prevent stroke in patients with carotid artery stenosis. Treatment options including carotid endarterectomy (CEA) and carotid artery stenting (CAS). Hence, the investigators aim to compare carotid artery stenting (CAS) with carotid endarterectomy (CEA) in terms of long-term prognostic endpoints. Also, CEA and CAS result in different postoperative geometric features of carotid arteries that entail relevant modifications of rheological parameters, that may be associated with the risk of local complications and carotid artery restenosis. Finally, long-term and sustained cognitive benefits after carotid artery revascularization need further research and evidence.
Purpose: The purpose of this study is to evaluate the Delay Alternating with Nutation for Tailored Excitation (DANTE) SPACE sequence in clinical studies to determine whether it can provide more useful information for clinical diagnosis. Participants: 100 participants with concern for intracranial vascular disease scheduled to undergo a clinical vessel wall MRI will be recruited. Procedures (methods): Patients with concern for intracranial vascular disease scheduled to undergo a clinical vessel wall MRI who will have an additional non-FDA approved sequence (DANTE SPACE) added to their clinical scan. The investigational sequence requires less than 15 minutes and will be added following the standard MRI sequence.
