NCT01462071
Background: A low amount of red blood cells in the blood of patients with limited kidney function is a well known problem. Besides the lack of substances in the blood like iron or erythropoietin the shortened survival of red blood cells leads to the low red blood cell count. Red blood cells of patients on kidney replacement therapy (dialysis) die earlier than those of healthy persons. They live only about 70 days compared to 120 days in healthy humans. Today little is known about the causes for the shorter survival of the red blood cells in patients on dialysis. Because inflammation leads to a shorter life of the red blood cells in people suffering from several diseases leading to inflammation we would like to learn about the role of inflammation in the shortened life of red blood cells of dialysis patients. When red blood cells are dying the content is broken down to several substances. One of these substances is the gas carbon monoxide (CO). The carbon monoxide is exhaled with the breath. The more red blood cells die the more CO is exhaled. That's why we can calculate the lifespan of the red blood cells when we measure the amount of CO in breath at the same time as the red blood cell count in the blood. Aim of the study: We aim to learn about the influence of inflammation of on red blood cell survival in dialysis patients. To look for factors with effect on inflammation or red blood cell survival, for example type of dialysis access, medication or kind of dialysis treatment. Study procedures: Over the course of the 18 month study, 6 observational assessments will take place. If the patient experiences a situation with increased inflammation during the study period (for example any kind of infection or intervention) up to two more study visits will take place. Each study visit will include blood sampling, performed without the need for an extra needle stick, and a breath sampling in order to calculate the red blood survival and to measure markers for inflammation in the blood. The breath sample will be taken using the easy to use GaSampler device developed by a company called Quintron especially for medical breath sampling. In order to get a sample of air at the patient's home for calculation of carbon monoxide produced in the body we will ask the patients to take home an open empty plastic bottle before each study visit. The bottle should be kept overnight on a table or sideboard in the apartment. Before leaving home for hemodialysis or in clinic visit the patient will seal the plastic bottle with the top, take it to the dialysis center and hand it to the research staff. Risks: The amount of the additional blood drawn is 30 ml; this is the amount 2 tablespoons, at each study visit. This does not harm the patient. The breath sampling does not imply any risk.
NCT00077636

NCT01395784
The ability of pioglitazone (PIO) to alter the effects of opioids in humans has not been characterized in a controlled laboratory setting. Accordingly, the proposed investigation seeks to examine the effects of PIO on oxycodone, one of the most commonly used and abused opioid drugs in the U.S. (Davis et al., 2003). More specifically, the primary aim of this investigation is to characterize the subjective effects of oxycodone under maintenance on various doses of PIO (0, 15, and 45 mg) in non-dependent, prescription opioid abusers. Secondary aims of the study are to examine the influence of PIO on the analgesic, cognitive, and physiological effects of oxycodone.
NCT02140372
This is a pilot study. Volunteers will be given 1.8 mg (1.2 mg followed by 0.6 mg one hour later), 1.2 mg, or 0.6 mg of colchicine. Blood will be collected prior to drug administration, 2 hours after colchicine administration, and 24 hours after colchicine administration via the antecubital vein and evaluated for markers of platelet activity and inflammation.

NCT00002766
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. It is not yet known which regimen of combination chemotherapy is more effective for acute lymphoblastic leukemia, lymphoblastic lymphoma, or chronic myelogenous leukemia. PURPOSE: This randomized phase III trial is studying two different chemotherapy regimens and comparing them to see how well they work in treating adults with acute lymphoblastic leukemia, lymphoblastic lymphoma, or chronic myelogenous leukemia.
NCT01343667
The objective of this study is to provide an ongoing evaluation of clinical outcomes associated with the GORE Flow Reversal System and the GORE Embolic Filter when used for embolic protection during carotid artery stenting.
NCT00774501
Liver tumors are hard to treat with radiation because the liver moves every time you breathe. The purpose of this study is to test a new and possibly more accurate way of treating liver tumors. When a person is asleep under anesthesia, it is safe to stop breathing motion for a while. The liver will stop moving and radiation can be given to a liver tumor. The study is being done to see if radiation can be given to liver tumors safely and accurately in this way.
NCT01212289
Cardiac surgery requiring use of a heart-lung machine, also known as cardiopulmonary bypass (CPB) can induce abnormalities in blood coagulation (clotting) that lead to excessive blood loss during and after operation. While of significant concern in adults, this problem takes on even greater importance in children due to the simple fact that they have a smaller blood volume. It is well known that if a child has previously undergone a heart operation, they are at increased risk of bleeding should more cardiac surgery be required ("reoperation"). The processes regulating blood coagulation are extraordinarily complex, and little is known about the exact mechanisms that contribute to the increased bleeding associated with cardiac reoperation in children. Rotational thromboelastometry (ROTEM®) is a technology that can provide, at the bedside, detailed information about coagulation abnormalities. While not currently approved for general use in the United States, in Europe ROTEM® has been used to guide administration of the blood products in surgery based upon determination of specific coagulation abnormalities. Importantly, there is now evidence that guidelines for transfusion therapy based on ROTEM® reduce transfusion requirements thus decreasing patient exposure to blood products. Whether the use of ROTEM® has potential benefit for pediatric cardiac surgical patients has not been studied. Accordingly, the present study was designed to provide preliminary data comparing coagulation profiles between children undergoing cardiac reoperation to those having primary procedure. The investigators hypothesize that ROTEM® analysis will detect a pattern of impaired coagulation in children undergoing reoperation. The overall objective of the four assays of ROTEM® analysis therefore, is to provide information that can be used to devise a rational transfusion protocol for pediatric cardiac surgical subjects.

NCT00902174
A multinational, multicenter, double blind, placebo-controlled study evaluating the efficacy and safety of imatinib as an add-on therapy in the treatment of patients with severe pulmonary arterial hypertension (PAH).
NCT02045927
This study looks to assess whether monitoring sedation status in mechanically-ventilated Medical Surgical Intensive Care Unit (MSICU) patients using Bispectral index (BIS) monitor-augmented sedation monitoring as opposed to Richmond Agitation Sedation Scale (RASS) score is associated with decreased duration of mechanical ventilation. Investigators hypothesize that using BIS monitors to help monitor depth of sedation in mechanically ventilated ICU patient will result in a decreased duration of mechanical ventilation when compared to solely utilizing clinical sedation scales such as RASS.

NCT01370005
This trial will evaluate safety and efficacy of BI 10773 in hypertensive patients with type 2 diabetes. Since hyperglycaemia and hypertension are key risk factors for both micro- and macrovascular complications, assessment of both glucose and blood pressure lowering effects of BI 10773 in hypertensive patients with type 2 diabetes could provide clinically highly relevant, new information for the use of BI 10773
NCT00828737
Patients with moderate to severe renal impairment scheduled for a magnetic resonance imaging (MRI) scan and injection with a contrast agent, Gadovist, will be asked to participate. The administration of contrast agents that contain gadolinium such as Gadovist might increase a potential risk to develop a rare condition called nephrogenic systemic fibrosis (NSF) in patients with renal impairment. This study is to assess the potential risk to develop NSF in patients with renal impairment after the administration of Gadovist. Patients who are enrolled in this study will receive a Gadovist enhanced MRI scan which was prescribed by the referring doctor. After the MRI scan the patient will be included in a two year follow-up period to assess if signs or symptoms suggestive of NSF have appeared.
