The principal objective is to evaluate the changes in biomarkers of oxidative stress and,plasma amino acids, as well as improvement of clinical symptoms and brain function
The purpose of this trial is to determine the efficacy of spinal cord stimulation, using wire leads, to produce an effective cough in patients with spinal cord injuries.
The impact of neurological disorders is enormous worldwide, and it is increased in poor settings, due to lack of diagnosis and treatment facilities as well as delayed management. In sub-Saharan Africa, the few observational studies conducted for the past 20 years show that neurological disorders accounted for 7 to 24% of all admissions. Central nervous system (CNS) infections were suspected in one third of all patients admitted with neurological symptoms, with a specific microbial aetiology identified in half of these. Most CNS infections may be considered as "severe and treatable diseases", e.g. human African trypanosomiasis (HAT), cerebral malaria, bacterial meningitis, CNS tuberculosis etc. If left untreated, death or serious sequels occur (mortality rates were as high as 30% in the above mentioned studies), but the outcome may be favourable with timely and appropriate management. In poor settings, such conditions should be targeted in priority in the clinical decision-making process. Unfortunately, most neuro-infections present with non-specific symptoms in their early stages, leading to important diagnostic delays. Moreover, they require advanced diagnostic technology, which is not available in most tropical rural settings: here, you have to rely on clinical judgment and first-line laboratory results, whose confirming or excluding powers are limited or unknown. Several rapid diagnostic tests (RDTs) have been recently developed for conditions like malaria or HIV, but their diagnostic contribution has not been evaluated within a multi-disease approach. Thus, this research aims at improving the early diagnosis of severe and treatable neglected and non-neglected infectious diseases which present with neurological symptoms in the province of Bandundu, Democratic Republic of Congo (DRC), by combining classic clinical predictors with a panel of simple point-of-care rapid diagnostic tests. The evaluation of existing algorithms and elaboration/validation of new guidelines will be described in a subsequent protocol.
Background: - Information and samples collected from participants in medical research studies can be useful even after the original study is complete. Researchers can use the information and samples to learn more about multiple sclerosis or other immune system disorders. They can also be used for research into other disorders. Researchers would like to get permission to use samples collected from older studies to launch new lines of research. Objectives: - To look at information and samples from earlier National Institutes of Health Neuroimmunology Branch studies. Eligibility: - People who provided samples and medical information for earlier studies. Design: - Researchers will contact people who took part in earlier studies. Researchers will ask if they can study previously collected data and samples. - Data and samples may include physical exam data and psychological test results. Imaging study results are included. Preserved samples of body fluids and tissues may be studied. These include blood and urine samples. - No new treatment will be provided as part of this research study.
This study in patients with schizophrenia is designed to provide preliminary evidence of the safety, tolerability, and pharmacokinetics as well as the effects on cognitive function of 2 doses of EVP-6124 compared with placebo when given with the patient's usual antipsychotic medication.
Stress (tako-tsubo) cardiomyopathy (SC) is a rapidly reversible form of acute heart failure reported to be triggered by stressful events and associated with a distinctive left ventricular (LV) contraction pattern. SC mimics acute coronary syndrome and is accompanied by reversible left ventricular apical ballooning in the absence of angiographically significant coronary artery stenosis. sympathetic activity dysfunction appears to play a very important role in the pathophysiology of takotsubo cardiomyopathy. In most cases, myocardial scintillography with 123Imetaiodobenzylguanidine (MIBG) showed altered captation of the radiotracer in several heart segments. In particular, the apical myocardium has poor sympathetic innervations and an uptake reduction in MIBG tracer. A hypothesis for this finding could be that the intense discharge of adrenalin, acting on heart segment with different and abnormal innervation, may produce a transient heart failure characterized by a particular shape of the left ventricle. While studies have shown that heterogeneous MIBG distribution, decreased MIBG uptake and increased norepinephrine content were completely prevented by α-lipoic acid or by L-acetyl carnitine administrations in diabetic cardiomyopathy, no studies have examined the effects of these therapies on tako-tsubo cardiomyopathy. On this basis, the investigators study will evaluate whether the dysfunction of adrenergic cardiac innervation, evaluated by MIBG, persist after previous experience of transient stress-induced cardiac dysfunction. Moreover, the investigators will assess whether the medications that restore sympatho-vagal alterations in diabetic cardiomyopathy, such as α-lipoic acid and L-acetyl carnitine, will improve the adrenergic cardiac innervation, in patients with SC.
Background: - People with motor neuron disorders have changes in the parts of the brain that control movement. Some tests that are currently used to study these changes are magnetic resonance imaging (MRI) and transcranial magnetic stimulation (TMS). We don t know if MRI scans and TMS give the same results if done at different times in the same person. Researchers want to see if these tests produce different results if given to healthy adults on two separate occasions. Objectives: - To test the reliability of different tests of the brain used to study motor neuron disorders. Eligibility: - <TAB>Healthy individuals at least 35 years of age who have no history of neurological disorders and take no medications. - <TAB>Pregnant women may not participate. Design: - Participants will be screened with a medical history and physical exam. - Participants will have two testing visits 1 to 6 months apart. - The first visit will have three parts. The first part is a neurological exam to test strength, sensation, reflexes, and coordination of movement. The second part will be TMS tests. The third part will involve an MRI scan to study the parts of the brain that control movement. - At the second visit, participants will have MRI scanning only.
The purpose of this study is to collect biofluid samples for the banking and usage in ALS research. Through comparison of these samples, the researchers hope to learn more about the underlying cause of ALS, as well as find unique biological markers, which could be used to develop new therapies.
Metabolic disorders such as diabetes mellitus, glucose intolerance and possibly metabolic syndrome can induce a peripheral neuropathy. To investigate the effect of physical training and diet education on neuropathic symptoms and neurophysiological parameters of patients with metabolic neuropathies.
Multiple Sclerosis (MS) is a complex multi-factorial disease, with underlying both genetic and environmental factors. Different populations have different susceptibility to MS. The disease is characterized by 2 main phenotypes: relapsing-remitting or progressive course. Clinical disability is due to distraction of the central nervous system (CNS) myelin. Repair processes are mainly noted after the acute relapse - and recovery of function can be spontaneous. However, in severe relapses sometimes there is need for STEROID TREATMENT. For the long term prophylaxis - following the increased understanding of the disease, in the last 10-15 years, there are new immunotherapies available (COPAXON / TEVA; Interferon -beta). However these can attenuate the disease (reduce the number of relapses per year) but cannot cure it. Also, they are beneficial in only ~40 % of the Relapsing -Remitting patients. Currently there are no biomarkers available for MS (other than oligoclonal Immunoglobulin G (IgG) in the cervical spine fluid (CSF) - which helps confirm diagnosis but require an invasive procedure and are not correlated with disease activity nor response to therapy) and monitoring of MS and its treatment is by magnetic resonance Imaging (MRI) - which is an expensive procedure. Dr Hossam Haick from the Technion developed an electronic nose based on nanomaterials for diagnosis of diseases (e.g., cancer, kidney failure, etc.) via breath samples.The research hypothesis is that Biomarkers of CNS inflammation and/or neurodegeneration and/or CNS repair in persons with MS can be detected by the "electronic nose".
