Filter by:The study will test whether damage of the heart nerves appears in patients before they develop diabetes.
This study aimed to investigate effects of physical training on exercise capacity and changes of heart rate variability (HRV) at rest, during exercise, and post-exercise in the patient with diabetes with autonomic neuropathy (DAN).
The purpose of this study is to determine if non-dilated retinal photography in the emergency room improves the diagnosis of papilledema (optic nerve swelling) in patients with neurologic disease compared to direct ophthalmoscopy.
The central hypothesis in the present project is that general anesthesia may alter autonomic control such that perioperative coronary blood flow (CBF) is significantly disturbed. These disturbances in coronary blood flow may contribute to the development of myocardial ischemia in the perioperative period. Furthermore, patients with an intrinsically altered autonomic sympathetic innervation, like diabetics, are even more prone to develop perioperative disturbances in coronary blood flow. Here the researchers will investigate what the direct effects are of general and locoregional anesthesia on the CBF. Furthermore, the researchers aim to evaluate whether diabetic subjects show more disturbed CBF responses to anesthesia as compared to non-diabetics.
The goal of this clinical research study is to find the highest tolerable dose of DNX-2401 that can be injected directly into brain tumors and into the surrounding brain tissue where tumor cells can multiply. A second goal is to study how the new drug DNX-2401 affects brain tumor cells and the body in general.
Patients with failed extubation stay significantly longer in an intensive care unit (ICU) and have a higher mortality rate, than those intubated successfully. Reintubation is associated with life-threatening complications and a poor prognosis. Functional respiratory tests are frequently used as weaning parameters, however, they are not accurate enough to predict extubation failure. The incidence of swallowing dysfunction is underestimated, mainly among patients whose intubation lasts longer than 48 h.We previously observed that the assessment of the swallowing function and oropharyngeal motricity, conducted by the physiotherapist before extubation could be helpful for making decisions to extubate patients intubated for over 6 days. The objective of this study is to validate a scale previously devised and used for physiotherapist bedside evaluation of the swallowing function and oropharyngeal motricity, among patients intubated for over 6 days, to determine whether this scale is a good predictor of airway secretion-related extubation failure.Expected results : to validate a scale previously devised called " physiotherapist evaluation of the swallowing function and oropharyngeal motricity before extubation" by the mean of a multicentric study. In our hypothesis the clinical parameters studied could be predictive of extubation failure. Then, this evaluation could help the medical decision in the choice of the good time for extubation. The final objective is to lower the mortality related to extubation failure.
This study (https://pdrisk.ninds.nih.gov) will determine if people who have risk factors for Parkinson disease (PD) have biomarkers (objective ways to measure a disease process) that show that the disease process is actually going on, and if people who have abnormal biomarkers go on to develop PD during several years of follow-up. Biomarkers of Parkinson disease (PD) might identify people who are healthy now but may develop the disease later in life. Healthy volunteers and people who have certain risk factors for developing PD who are between 18 and 70 years of age may be eligible for this study. People with the following risk factors are included: - Family history of PD - Loss of sense of smell - Fall in blood pressure when standing up - REM behavior disorder (a type of sleep disturbance) Participants undergo the following tests and procedures: - Screening examination - Medical and neurological history and physical examination - Tests or rating scales for movement, sense of smell, mood, attention, fatigue, pain, and thinking. - Measurement of blood pressure and pulse rate while lying down and then standing up - Blood draw for genetic testing - Inpatient testing at the NIH Clinical Center for 2-3 days, including: - Measurements while blowing against a resistance - Measurements of blood pressure and pulse rate - Blood draws for levels of various chemicals - PET and MRI scanning - Lumbar puncture (spinal tap) - Electrocardiogram - Skin electrical conduction test (test of sweat production) - Skin and core temperature measurements - Transcranial ultrasound (sound-wave test of the head) - Follow-up testing (up to five visits in 18-month intervals) to repeat some of the tests listed above, excluding the genetic testing and spinal tap
The length of tracheal intubation may affect the subsequent ventilation with a laryngeal mask during percutaneous tracheostomy.
This study is being conducted to determine the safety, tolerability, and pharmacokinetics (PK) of three different doses of an investigational medication, EVP-6124, in individuals with mild to moderate Alzheimer's disease who are also taking an Alzheimer's medication (AChEI [acetylcholinesterase inhibitor]: either donepezil or rivastigmine). In addition, PK of AChEI medications will be assessed. Cognitive function will be evaluated on an exploratory basis.
The purpose of this study is to determine the cause of low blood pressure in selective patients who have problems with their involuntary (autonomic) nervous system. These patients frequently have had symptoms throughout their life, and their disorder might have a genetic basis. The biochemical, physiological and pharmacological procedures in this study should help us define the problem and perhaps lead to more effective treatment.
