Filter by:The purpose of this study is to understand what causes a continuing fatigue for a long time with a number of symptoms occurring at the same time (Chronic Fatigue Syndrome-CFS). Epstein Barr Virus is among the group of viruses that have been associated with a continuing fatigue for a long time with a number of symptoms occurring at the same time, but the cause is still unknown.
The metabolic syndrome is a medical condition defined by high levels of cholesterol in the blood, high blood pressure, central obesity (gain in fat around the region of the stomach), and insulin resistance (body responds less well to insulin). This state of impaired insulin resistance can lead to type 2 diabetes mellitus, which is one of the most common metabolic disorders in the U.S. Numerous studies have shown an inverse relationship between insulin resistance and testosterone levels in men, however, causality has not been established. This protocol investigates the role of testosterone in modulating insulin sensitivity in insulin resistant states such as the metabolic syndrome. The hypothesis is that testosterone administration will improve insulin sensitivity.
The metabolic syndrome has been recognized as a proinflammatory state. It has been shown that many different diets such as Mediterranean diet, DASH diet, Foods with low glycemic index and low saturated fat diet, independent of weight loss, may be effective in improving the metabolic syndrome. Our objective was to evaluate the effect of Ramadan fasting on High-sensitive C-reactive protein (hs-CRP) and fibrinogen levels in metabolic syndrome.
The metabolic risks associated with obesity are closely correlated with central (abdominal), rather than a peripheral (gluteofemoral) fat pattern It has been shown that weight loss after bariatric surgery is followed by metabolic improvements. The amount of fat lost from each site may be independently regulated. Very scant information is found in the literature regarding the relative changes in different fat body compartments, and their effect on the improvement of the metabolic profile. In this study we define the absolute and relative changes in the different adipose tissue compartment after weight loss surgery
The pathogenesis of ARDS appears to be from damage to the alveolar-capillary barrier, which is composed of the microvascular endothelium and the alveolar epithelium. This damage may occur from direct or indirect lung injury. The mechanism of injury to the alveolar capillary barrier appears to be through neutrophil-mediated injury, pro-inflammatory cytokines, ventilator-induced lung injury with alveolar over distention and abnormalities of the coagulation system. This results in blood clot formation in the microcirculation of the lung. Thrombolytics can dissolve blood clots and result in increased blood flow to the organs. This treatment may benefit ARDS patients, thus the purpose of this study. Hardaway, et al.studied the effects of thrombolytics on ARDS in pigs. The experimental group showed improved oxygenation and survival as compared to controls. There was no bleeding complications noted with this therapy. Dr. Hardaway followed this animal study with a phase I clinical trial involving 20 patients with ARDS. The patients were treated with IV streptokinase or urokinase. Nineteen of the 20 patients showed an increase in PA02 after thrombolytic therapy. There were no significant bleeding complications in patients that were critically ill on ventilators. We propose an additional phase I pilot study to evaluate the effectiveness and safety of Tenecteplase for the treatment of ARDS. Unlike the other fibrinolytics studied in this disease state, Tenecteplase, is more fibrin specific and has increased resistance to plasminogen activator inhibitor (PAI-I) at greater levels than other available fibrinolytics. We have chosen an experimental dose escalation trial design of tenecteplase that has demonstrated initial safety trends in a Phase I acute ischemic stroke trial. The initial dose is 0.1 mg/kg IV and will increase to 0.2 mg/kg, 0.3 mg/kg, with a final cohort of patients receiving 0.4 mg/kg. Drug administration will be a single dose bolus in each cohort. Advancement of dose will occur if safety is not in question in the previous cohort. We hope this will provide an acceptable benefit risk ratio as the mortality of ARDS is approximately 30 - 60%. All patients will be closely monitored for any change in clotting parameters and signs of bleeding. Tenecteplase will be administered via a peripheral IV as described in the package insert.
Marfan syndrome is a hereditary connective tissue disorder. Many individuals with this condition die because of the associated heart and blood vessel abnormalities. This study will compare the effectiveness of two medications, losartan and atenolol, at slowing aortic root enlargement in individuals with Marfan syndrome.
pShoulder impingement syndrome is common and number of operations done per year is growing. The aim of this study is to compare the value of arthroscopic subacromial decompression (acromioplasty group) vs. diagnostic arthroscopy (control group) vs. supervised exercise therapy (conservative group) on subjects with chronic subacromial impingement syndrome. The results of treatment are measured at 3 months, 6 months, 12 months, 24 months, 5 years and 10 years. Primary outcome measures are pain at rest and activity (VASs) and secondary outcomes are functional assessment of the shoulder with Constant score and Simple Shoulder test (SST), global assessment of change , quality of life assessment (SF-36 and 15D) and costs. At 10 year follow-up, MRI imaging is obtained and the findings compared to baseline imaging.
The Polycystic Ovarian Syndrome (PCOS) is a common disorder related to ovulation problems. Clomiphene citrate (CC) is the drug of first choice for this condition. Nevertheless, CC has a detrimental effect over uterine receptivity. Raloxifene is a Selective Estrogen Receptor Modulator, that does not have a detrimental effect over the endometrium, and also increase the serum levels of FSH, thus, inducting ovulation. The objective of this study is to compare the ovulation rate in PCOS patients between clomiphene citrate and raloxifene in a double blind randomized trial.
The primary purpose of the study is to determine whether B-cell depletion with Rituximab has an effect on the oral, ocular and general disease manifestations in patients with primary Sjögren´s syndrome, that is, an effect on the symptoms of oral and ocular dryness, improvement of the glandular function and a beneficial effect on the general symptoms such as fatigue. The secondary purpose of the study is the investigate the underlying autoimmune and pathophysiological mechanisms in Sjögren´s syndrome.
The purpose of this study is to investigate whether the addition of a vaccine after participants reduced intensity transplant will be safe and beneficial. The vaccine used in this trial, called GVAX, will be made from the participants own leukemia cells, and will be given between 1-4 months after transplant. In recent years, researchers have discovered that GVAX vaccine made from the patient's own cancer calls that have been engineered in the laboratory to produce a protein called GM-CSF, can be effective in stimulating a powerful immune response specific to that cancer.
