Filter by:The primary objective of this study is to assess the activity on breathing parameters of 4 escalating doses of AVE0657 in comparison to placebo in patients with Cheynes-Stokes Breathing Syndrome.
Metabolic syndrome is a constellation of risk factors for cardiovascular disease. The prevalence of metabolic syndrome in persons with obstructive sleep apnea syndrome (OSAS) is known to be very high, about 70%. However, it is unclear whether this association is causal or not. Results of earlier studies have been conflicting. The investigators hypothesize that treatment with auto-titrating continuous positive airway pressure (auto-CPAP) for a duration of 3 months improves the metabolic syndrome in subjects with OSAS.
In wrists with carpal tunnel syndrome (CTS) the sonographically measured largest cross-sectional area (CSA) of the median nerve is increased. We compared the changes in largest CSA in wrists undergoing surgical decompression and wrists undergoing conservative treatment of CTS.
Visceral and somatic hypersensitivity as evidence of central sensory sensitization occur in the majority of Irritable Bowel Syndrome (IBS) patients. We recently demonstrated abnormal endogenous pain modulation as a cause of the sensitization in IBS and identified the underlying dysfunctional neuromatrix using functional MR-imaging (fMRI). Endogenous pain mechanisms regulate, fine-tune and integrate sensory and homeostatic, including neuroendocrine, immune and autonomic nervous system processes. Specific measures of sensitization and endogenous pain modulation correlate with clinical measures of somatic and neuropathic pain, suggesting usefulness as surrogate markers for clinical pain outcomes. Validation of experimental measures as surrogate markers in IBS would provide a considerable advance in pathophysiological and therapeutic research in this pharmacoeconomically burdensome disease.
The overall aim of this study is to explore the effects of flaxseed supplementation and determine whether it is a feasible and potentially effective dietary intervention among women with polycystic ovarian syndrome (PCOS). Women, ages 18-45, with clinically confirmed PCOS (N=20) will be scheduled for baseline measures and then instructed and given supplies necessary to follow a flaxseed supplemented (30 g/day) diet for a period of three months, whereupon follow-up measures will be taken. Subjects will be asked to resume their typical (unsupplemented) diet for another three months and a second set of follow-up measures will be taken. Baseline levels of bioavailable and total testosterone, fasting insulin, glucose, and triglycerides (TG), total/LDL/HDL cholesterol, body weight, degree of hirsutism and acne, and menstrual cyclicity will be compared to levels at 3 and 6 month follow-up. The overall hypothesis (based upon our work in men at risk for prostate cancer and data from one case-study conducted in a woman with confirmed PCOS) is that during the time women receive flaxseed supplementation they will experience reduced serum levels of testosterone, and total and LDL cholesterol, as well as clinical evidence of hirsutism. Given the pilot nature of this study, statistical analyses will be limited to simple descriptive statistics. We have observed no negative side effects, other than minor gastro-intestinal occurrences (i.e., temporary increased flatulence, borborygmi, increased number of stools, etc.) associated with flaxseed supplementation in our previous studies either with short or long-term use. Flaxseed supplementation will be discontinued if indicated and the events reported to the institutional review board.
The main purpose of this investigational (not approved by the FDA) Phase I research is to test whether transplantation of umbilical cord blood cells can be safely supplemented with a transfusion of a portion of these cells that have been sorted (collected from a special machine called a cell sorter) and then either infused a few hours after the standard transplant or for some patients grown in a special system in the laboratory prior to the transplant, designed to increase the number of stem cells transplanted. This system is currently in the early phases of testing.
We propose to use actigraphy (measured by activity watches) as a tool to quantify sleep disturbances in patients with orthostatic intolerance compared with healthy control subjects. In this pilot study, we will test the null hypothesis (Ho) that there are no differences in the sleep quality between patients with orthostatic intolerance and healthy control subjects.
Focal dermal hypoplasia, or Goltz syndrome, results from genetic changes, or mutations in the PORCN gene located on the X chromosome. This neurodevelopmental disorder is characterized by birth defects of the skin, skeleton, eyes, and in some cases other organs. Our team is working to obtain a better understanding of how mutations in PORCN lead to the clinical features of Goltz syndrome. We are also trying to identify the genetic change in those patients where no mutations in PORCN have been found. We are also investigating conditions with phenotypes similar to Goltz syndrome to determine if they also have mutations in PORCN. We are collecting blood samples from patients and their parents. DNA from these samples is isolated and then used for genetic testing. We also review medical records to compare clinical symptoms with the detected mutations to determine if there is a correlation.
The purpose of this study is to describe the hormones controlling fluid balance in pediatric patients with nephrotic syndrome. Further more, an analysis of the urinary and plasma proteins will be done using proteomics. Different composition of proteins in the urine or plasma might indicate if the patients will respond to treatment or not.
Children with Down syndrome (DS) have language development particularities that have negative effects in the communication capacity. By this way, Augmentative and Alternative Communication (AAC) is indicated to this population. The aim of this study was to verify the AAC impact in the lexical gain of children with DS.
