Filter by:In the proposed study, the investigators examine in older adults with Type 2 diabetes the impact of beginning insulin therapy on the orthostatic drop in blood pressure as well as the response of arterial blood pressure and Doppler measures of cerebral blood flow during upright tilt. The investigators hypothesize that in older adults with Type 2 diabetes, the cardiovascular effects of insulin would precipitate or worsen orthostatic intolerance not present at baseline.
Background: The presence of orthostatic hypotension (OH) as a consequence of blood volume redistribution during verticalisation in persons with spinal cord injury (SCI) is a common condition. Aims: To investigate the impact of three different types of electric stimulation (ES) (ES of the abdominal muscles versus ES of lower limb muscles versus simultaneously ES of abdominal and lower limb muscles versus control) on blood pressure stabilization and verticalisation-degrees between 0° and 70°. The hypothesis is, that the ES-induced contractions of the muscles cause a stabilisation respectively an increase of the blood pressure during the tilt-table test. Subjects: 20 Women and men, at least 18 years of age, following an acute and traumatic SCI, with a lesion level above T6, an American Spinal Injury Association (AIS) Impairment Scale A,B or C and a diagnosis of OH (by tilt table test) were eligible for the study. Methods: Each patient underwent randomly three different types of ES sessions while being positioned on a tilt-table. The following sessions were planned: A) ES of the abdominal muscles B) ES of the lower limb muscles C) Combination of A and B D) Control session (=diagnostic session) Study type: Intervention Design: Prospective interventional study
Individuals with acute cervical spinal cord injury (SCI) can suffer from an excessive and prolonged fall in blood pressure when assuming an upright position, such as transitioning from lying to sitting or standing, a condition also known as orthostatic hypotension (OH). Due to a decrease in cerebral oxygenation, affected individuals can develop debilitating symptoms including lightheadedness, blurred vision, fatigue and even loss of consciousness. Recent evidence suggests that OH has a negative impact on cognition in individuals with SCI. Clinical observations suggest that OH can lead to neurological deterioration in individuals who may otherwise have a stable SCI. The presence of symptomatic OH prevented participation in 43% of physical therapy treatment sessions in a study of individuals with acute SCI despite the use of current treatment options. OH is known to adversely affect health, delay rehabilitation and prolong hospitalization in the acute phase of management of individuals who display it. Our team found OH was present in 41 of 55 (75%) patients with acute cervical SCI at our center in 2004. We plan to research the efficacy of a low-cost, non-invasive device known as transcranial electrical stimulation (TES) to manage OH in individuals with acute cervical SCI. Previous studies have shown that this device is safe to use in individuals with SCI, and has improved blood pressure control in non-SCI individuals. We hypothesize that in individuals with acute cervical SCI and OH, TES intervention will elicit an attenuation of the drop in systolic BP (SBP)in response to orthostatic stress. TES-induced differences will be most pronounced in those individuals with sparing of spinal autonomic pathways
An International, multicenter, epidemiological observational study investigating the prevalence of Transthyretin-Related Familial Amyloidotic Polyneuropathy (TTR-FAP) in participants with small fiber polyneuropathy of no obvious etiology.
Orthostatic hypotension is a major complication of hemodialysis and interferes with everyday activities in hemodialysis patients. Since information regarding the use of droxidopa in clinical trials relating to orthostatic hypotension of chronic hemodialysis patients is limited in Taiwan, this study is designed for evaluation the efficacy and safety profile of droxidopa on orthostatic hypotension treatment / prevention in hemodialysis patients.
The purpose of this study is to evaluate the effect of low dose versus high dose steroids vital signs of patients currently on steroids or recently treated with steroids undergoing major colorectal surgery. The investigators hypothesize that there will be no statistically significant difference in orthostatic hypotension (blood pressure measured on lying, sitting, and standing), blood pressure, temperature or heart rate in the standard and low dose groups.
The study is aimed to assess the efficacy of hand-grip in preventing orthostatic hypotension in 20 patients diagnosed with autonomic failure. Five healthy subjects will be studied for comparison. The investigators will evaluate the subjects while on tilt table for 10 minutes and than while mounted from lying down to 70 degrees for additional 10 minutes. Blood pressure, heart rate and symptoms will be continuously measured. First study will evaluate the blood pressure changes. Second measure will include hand-grip maneuver 1 minute before the erect positon. Trans cranial Doppler will assess the intracranial blood flow during the position changes.
The purpose of this study is to determine whether midodrine works against the symptoms of orthostatic hypotension caused by being on a tilt table.
This study is being done to study the combination of pyridostigmine and low-dose Droxidopa for the treatment of orthostatic hypotension.
In this study the investigators aimed 1. to investigate the prevalence of orthostatic hypotension in elderly nursing home residents. 2. to investigate whether the presence of orthostatic hypotension influences the chance of successful rehabilitation.
