Filter by:This is a large-scale, community-based, cross-sectional study to evaluate environmental and genetic risk factors for cardiovascular autonomic neuropathy in general Chinese population.
A large-scale, community-based, cross-sectional study was conducted to explore the extent to which risk factors associated with diabetic cardiovascular autonomic neuropathy (DCAN) in general Chinese population. A total of more than 2000 diabetic participants were recruited by using multiple stages sampling (first cluster sampling and then simply sampling). Data involved in demographic information, clinical biomarkers such as glucose and lipids profiles, medical and therapy history were collected. Every participants was complete DNA extracted and genotyped. Diabetic Cardiovascular autonomic functions were measured by using short-term heart rate variability (HRV) to evaluate the outcome of DCAN. Univariate and multiple variables analysis have been performed to examine potential environmental and genetic risk factors of CAN. In addition, clinical risk model, simply screening model and nonlinear system model such as artificial neural network was created, respectively.
This study aimed to estimate sensitivities and specificities of diabetic cardiovascular autonomic neuropathy (DCAN) diagnostic tests using the Bayesian approach without a gold standard in another independence dataset.The reference the values for the short-term HRV were calculated in the investigators' previous study (including 371 healthy subjects). This study dataset contained 200 diabetic patients who completed both the short-term HRV test and Ewing's test. Simultaneous inferences about the population prevalence and the performance of each diagnostic test were possible using the Bayesian approach without a gold standard.
A large-scale, community-based, cross-sectional study was conducted to explore the extent to which genetic, environment and its interactions associated with cardiovascular autonomic neuropathy (CAN) in general Chinese population. A total of more than 2000 participants were recruited by using multiple stages sampling (first cluster sampling and then simply sampling). Data involved in variables of genetic, environment were collected. Every participants was complete DNA extracted and genotyped by using single nucleotide polymorphism (SNP). Cardiovascular autonomic functions were measured by using short-term heart rate variability (HRV) to evaluate the outcome of CAN. Genetic analysis were employed to evaluate genetic variants, environmental risk factors and its interactions for CAN.
This study aimed to evaluate the reference values for the short-term heart rate variable (HRV), estimate the performance of cardiovascular autonomic neuropathy (CAN) diagnostic tests in the absence of a gold standard, and assess CAN prevalence in our cross-sectional dataset.
White matter tracts connect cortical areas to other parts of the cortex, to basal ganglia and to the brain stem and spinal cord. These tracts form the internal part of the brain and transmit the nervous impulses. Changes in brain white matter may serve as biomarkers for numerous neurological diseases. Diffusion Weighted Imaging (DWI) is a non-invasive MRI (Magnetic Resonance Imaging) technique providing information on white matter tracts (tractography) by studying water diffusion. Since it is based on complex mathematical models that only indirectly evaluates the underlying anatomy, tractography need to be validated before being used for research and clinical purposes. Several validation techniques were previously proposed, none of them being fully convincing in human.
The purpose of this study is to investigate the applicability and feasibility of the newly developed robot platform for upper extremity therapy ("ChARMin") in children undergoing neurorehabilitation.
The use of low-dose CBP dosed nightly at bedtime for FM was supported by the results of Tonix' TNX-CY-F202 Phase 2b study (also referred to as the BESTFIT Study). The TNX-CY-F202 study provided strong evidence that TNX-102 SL 2.8 mg dosed nightly results in beneficial effects upon pain, sleep and other FM symptomatology. The present trial is designed to assess the safety and efficacy of TNX-102 SL 2.8 mg tablets, taken daily at bedtime over 12 weeks to treat fibromyalgia.
Background: - Inflammation is how the body reacts to infection or injury. Infections or inflammation in the brain and nerves can be serious. There aren t always good tests to detect this. Researchers want to learn more about how diseases affect the brain and nerves to develop better tests and treatments. Objective: - To learn more about how inflammation and infections hurt the brain and nervous system. Eligibility: - People at least 2 years old with a diagnosis or suspected diagnosis of nervous system infection or inflammation. Design: - For some participants, a clinician outside of NIH will collect blood, tissue, and other samples. These will be sent to NIH and analyzed. - Other participants will have several visits to NIH. Children may not have all these tests. - Participants will have: - Medical history. - Physical and neurological exam. - Blood and urine samples collected. - Saliva collected. They will chew on a piece of sterile cotton for one minute. - Magnetic resonance imaging (MRI) scan. The scanner is a metal cylinder in a strong magnetic field. Participants will lie on a table that slides in and out of the cylinder. Participants will get a contrast agent through an intravenous (IV) catheter during the MRI. A needle will be used to guide a thin plastic tube (catheter) into an arm vein. - Lumbar puncture. Skin will be numbed and a needle will be inserted into the space between the bones in the back. Fluid will be removed. - Some participants may have optional study procedures. These may include eye tests, memory and thinking testing, tests with electrodes on the head, or skin biopsy.
The current study has the following objectives: 1. To determine predictors of time 2 and 3 (3 and 6 months post-ICU admission) depression, PTSD, satisfaction with life and quality of life in both patients and caregivers, after controlling for injury severity and impairment. 2. To determine factors associated with patient and caregiver satisfaction with medical care at time 2 and time 3. The investigators would thus be able to identify the best time point for intervention delivery, intervention targets, and risk factors for chronic psychological distress.
