NCT01282242
This study was jointly developed and is jointly led by investigators at Massachusetts General Hospital and the intramural division of NINDS. We are doing this research study to find out if Activase ® (also called alteplase or rt-PA) can safely be given to people with an acute ischemic stroke when their stroke onset was not witnessed making them ineligible for standard thrombolytic (clot busting) therapy. We also want to find out if rt-PA can help people recover better from their stroke. The purpose of this study is to: 1) see if it is safe to give intravenous (IV) rt-PA to people with unwitnessed stroke but with MRI evidence of early ischemic stroke, 2) see if rt-PA is effective if given to people who are selected for treatment based on MRI evidence of an early stroke, and 3) get information about this new MRI diagnostic methods for guiding stroke treatment.
NCT01828593
The purpose of the study is to evaluate the effectiveness of the oral nutritional therapy serum-derived bovine immunoglobulin protein isolate (SBI) 2.5 g twice a day (BID) and SBI 5.0 g versus placebo on supporting nutrient absorption in HIV+ subjects with HIV-associated enteropathy.
NCT01709201
The investigators goal is to pilot a substance use-related brief intervention (BI) for youth with chronic medical conditions, obtaining preliminary evidence of feasibility, acceptability and impacts of the approach for reducing substance use among this group.
NCT00100984
The main objective of this study is to compare the safety and efficacy of an enfuvirtide containing regimen to a nucleoside combination regimen. Resistance information will also be collected.
NCT02256969
In this research study, the investigators are looking at the effects of Meibomian Gland Probing (MGP) versus a sham (fake) procedure in patients with refractory MGD who have already tried traditional management with no success in resolving their clinical signs (as seen by their ophthalmologist) or their symptoms. The investigators are also evaluating the effects of using two (2) post-procedural medication treatments: Blephamide or GenTeal PM Night-Time to determine if treatment after the MGP procedure has an effect on its outcome.
NCT00883792
Colorectal cancer (CRC) is a major burden in western countries. The disease develops from precursor lesions during a long time-interval. Colonoscopy can detect and remove CRC precursor lesions and may thus be effective for CRC prevention. Many national and international health organisations demand evidence from randomised trials to reduce incidence or mortality of the target disease before advocating population-wide cancer screening. However, while colonoscopy screening for the prevention of colorectal cancer is established in the United States and several European countries, no randomised trials exist to quantify the possible benefit of colonoscopy screening. NordICC is a randomised trial investigating the effect of colonoscopy on CRC incidence and mortality. NordICC is a multicentre, randomised trial in Nordic countries, the Netherlands and Poland. A minimum of 66 000 individuals, age 55-64 years, are drawn randomly from the population registries in the participating countries. 22 000 are invited for once-only colonoscopy (2:1 randomisation). Expected work-load with 50% compliance will be 11,000 colonoscopies. At the screening examination, all detected lesions are biopsied and removed whenever possible. The remaining 44 000 individuals (control group) are not offered any screening examination (care as usual).The primary study aims are CRC incidence and CRC mortality after 15 years of follow-up, with an interim analysis after 10 years of follow-up. In an intention-to-treat approach, a risk reduction of CRC mortality of 25% in the colonoscopy screening group compared to the control group is expected after 10 years follow-up, estimating 50% compliance in the screening group.
NCT02178787
Cerebral autoregulation (CA) is a complex mechanism that serves the essential and vital purpose of controlling cerebral blood flow and metabolism. A stable and optimal brain blood flow is imperative for normal brain function. Diabetes Mellitus (DM ) is associated with microvascular disease that alters CA and also with autonomic failure that may lead to orthostatic hypotension (OH). These conditions may lead to decreased brain blood flow in upright position. This observational study will compare two technologies that evaluate brain blood flow during standing up and other maneuvers in people with and without type 2 diabetes. These technologies are transcranial Doppler and UTLight technology (CerOx). This study will determine the safety and feasibility of CerOx technology for continuous monitoring of cerebral blood flow.
NCT00494507
The purpose of this study is to compare Dichlorphenamide with placebo (an inactive substance) for prevention of episodes and for improvement of strength in hyperkalemic (HYP) and hypokalemic (HOP) periodic paralysis. This study will also look at the long-term effects of Dichlorphenamide in periodic paralysis.
NCT02947984
The purpose of this study is to determine the best radiation dose for participants with meningioma that has grown back after previous surgery, or which the surgeon has been unable to remove completely. This research study is designed to determine whether a higher dose of radiation will decrease the likelihood that the tumor will grow back, compared to the probability of re-growth that occurs after standard radiation doses.
NCT01273805
Hydroxychloroquine is approved for the treatment of non-cancerous illnesses such as rheumatoid arthritis and systemic lupus erythematous. Researchers in the laboratory have tested tumors from patients with pancreatic cancer and have discovered that they have certain pathways inside the cells that promote growth and survival of the tumor. Hydroxychloroquine may inactivate these pathways and results in the death of pancreatic cancer cells.
NCT01747772

To measure liver stiffness with sonoelastography in adults with suspect diffuse liver disease who will undergo non-focal liver biopsy as part of their routine clinical care 2. To assess the sensitivity and specificity of sonoelastography for the detection and staging of liver fibrosis 3. To evaluate the effect of steatosis and inflammation on the estimation of liver fibrosis using sonoelastography
