There are about 173942 clinical studies being (or have been) conducted in United States. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The aim of the study is to prospectively compare the effectiveness of diverse incentives on physical activity behaviour, in a cohort of newly-enrolled, adult members of the Vitality health promotion programme based in South Africa.
Women with Breast Cancer who do not respond to chemotherapy may undergo months of treatment with little or no change in tumor size or overall outcome. The Researchers have demonstrated a previously undescribed "metabolic flare" response observed very early in neoadjuvant treatment in breast cancer patients. The research can determine that this flare is predictive of overall therapy response and is due to both an inflammatory reaction and cell death induced by cytotoxic therapy.
The last two decades have witnessed an explosion of new research documenting the deleterious impact that thyroid disease has on pregnancy and the postpartum period, in relation to miscarriage preterm delivery intelligence quotient of the unborn child and health of the mother postpartum. Both subclinical hypothyroidism and thyroid antibody positivity in euthyroid women have been associated with miscarriage and preterm delivery. Approximately 5% of all pregnant women have a thyroid disorder. both spontaneous miscarriage and preterm delivery. Systemic lupus erythematosus (SLE), an autoimmune disorder of unknown etiology, has also been documented to negatively impact pregnancy. Women with Systemic lupus erythematosus (SLE)have increased rates of miscarriage and preterm delivery. Women with Systemic lupus erythematosus (SLE) also have increased rates of hypothyroidism and autoimmune thyroid disease (AITD, defined as the presence of thyroid antibodies with or without thyroid dysfunction). Preterm delivery (PTD), defined as birth prior to 37 weeks gestation, is the leading cause of neonatal mortality and morbidity in the United States. Although risk factors for preterm delivery exist, the majority of women have no known risk factors. Recently, both hypothyroidism and autoimmune thyroid disease have also been linked to preterm delivery. Given the increased prevalence of negative outcomes documented in pregnant women with thyroid disease, and the increased rates of hypothyroidism and Autoimmune thyroid disease in women with Systemic lupus erythematosus (SLE), the investigators determined that Autoimmune thyroid disease was associated with both preterm delivery and miscarriage. This has led to this application to begin a pilot randomized clinical trial of thyroxine in autoimmune thyroid disease in systemic lupus erythematosus pregnancy.
This is a prospective trial of single incision versus standard 4-port laparoscopic splenectomy. The hypothesis is that there may be a difference in wound infection rates, operative time, doses of analgesics post-operatively, and patient/parent perception of scars. However, the technical difficulty is considerable and the primary outcome is operative time which will be expressed in minutes.
The purpose of this study is to assess distribution, metabolism, and excretion of radio-labelled AZD9742 administered as a 2-hour infusion to healthy male volunteers.
Subjects in this study have been diagnosed with pulmonary hypertension and their doctors have referred them for an exercise test as part of their normal, routine care. The exercise test will either be a treadmill test or a 6 minute walk test. During a treadmill test, a patient typically walks on a treadmill while their heart is monitored using an electrocardiogram, which records the electrical activity of the heart through 10 small electrode patches attached to the skin of the chest, arms and legs. Additionally, heart rate and blood pressure are monitored throughout the test. A 6-Minute Walk test requires patients to walk for up to 6 minutes to determine how far they can go in order to measure the heart function related to exercise. The purpose of this study is to measure internal heart pressures using a device called Noninvasive Cardiac Output Monitoring (NICOM) during an exercise test. Normally heart pressures are measured during invasive (meaning that doctors have to go inside the body using a needle or surgery) heart procedures. The NICOM device is non-invasive which means the investigators do not have to go inside the body to obtain the heart pressure measurements. In this study, the investigators will evaluate the non-invasive measurements provided by the NICOM device during the exercise test and see how it relates to information from some of subjects' past heart procedures. This research is being done to devise better, less invasive ways to assess disease severity, track disease progression and evaluate response to therapy. The NICOM device is approved by the US Food and Drug Administration (FDA) to measure heart pressures. This device is usually used when a patient can't undergo a right heart catheterization. In this study, the investigators are using the device to gather heart pressure measurements for research during the exercise test that is scheduled as part of the subjects' normal, routine care. The research data is being used to devise better, less invasive ways to assess disease severity, track disease progression and evaluate response to therapy. The NICOM device is made by Cheetah Medical.
This research trial studies biomarkers in bone marrow and blood samples from patients with prostate cancer treated with ketoconazole. Studying samples of bone marrow and blood from patients with prostate cancer in the laboratory may help doctors learn more about changes that occur in deoxyribonucleic acid (DNA) and identify biomarkers related to cancer.
In this project we will conduct a pilot study of a brief intervention to reduce teen tobacco, alcohol and drug use that primary care dental practitioners can provide in their offices.
This study will consist of middle-aged Caucasian non-failing subjects with high blood pressure who are homozygous for a gene that confers increased risk of developing heart failure, the Glycine 83 variant of the Ka renal chloride channel (ClC-Ka Gly/Gly 83), or middle-aged Caucasian non-failing hypertensive subjects who lack the heart failure risk gene, the wild-type Arginine 83 Ka renal chloride channel (ClC-Ka Arg/Arg 83). Subjects on standard therapy for high blood pressure with an angiotensin converting inhibitor (ACEI) or angiotensin receptor blocker (ARB) will be randomized to additional treatment with eplerenone (an aldosterone antagonist) or placebo, and assessed for changes in echocardiographic left ventricular hypertrophy (LVMI). Secondary endpoints will assess left ventricular remodeling and other echocardiographic variables. The investigators hypothesize that subjects homozygous for the CLCNKA risk allele will have a greater response to eplerenone in terms of reductions in LVMI than those lacking the risk allele.
The purpose of this research study is to see if Eculizumab (Soliris®) can safely be used in addition to conventional therapy in patients with active ANCA (Antineutrophil Cytoplasmic Autoantibodies ) vasculitis and lead to a more rapid decrease in disease activity. ANCA vasculitis is an inflammation of the small vessels whereby ANCA antibodies inappropriately activate one's own white blood cells (neutrophils) and cause damage to the small blood vessels.
