There are about 13332 clinical studies being (or have been) conducted in Netherlands. 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.
This study is an international, multi-center, open-label study designed to provide oral treprostinil (UT-15C) to eligible subjects with pulmonary arterial hypertension who have completed the TDE-PH-310 study. The purpose of this study is to assess the long-term safety of UT-15C and to assess the effects of long-term treatment with UT-15C on exercise capacity.
This is an international, multicenter, randomized, double-blind, placebo-controlled, event driven study in subjects with pulmonary arterial hypertension.
A prospective, open, randomized trial, in which the investigators aim to achieve optimal immunosuppression after renal renal transplantation with maximal reduction of side effects, especially of vascular injury, chronic allograft nephropathy, osteoporosis and malignancies. Immunosuppression without steroids and CNI minimization is compared to standard immunosuppression, consisting of tacrolimus OD, mycophenolic acid and corticosteroids.
The incidence of type 2 diabetes mellitus (T2DM) is rapidly growing. Patients with T2DM are at increased risk of developing long term micro- and macrovascular complications. Subjects with impaired glucose tolerance (IGT) show increased blood glucose levels after an oral glucose load. These subjects have a markedly increased risk of later T2DM development. T2DM development can be prevented or delayed by lifestyle modifications. To support lifestyle changes and reduce the risk of T2DM development, foods containing functional ingredients are being developed. An interesting functional ingredient is protein hydrolysate. An egg protein hydrolysate has been experimentally shown to improve endothelial function, to inhibit plasma angiotensin converting enzyme (ACE) and to reduce blood pressure in rats. Egg protein hydrolysate could thus be a interesting ingredient to treat the cardiovascular dysfunction associated with T2DM. In the present study, the effects of egg protein hydrolysate will be evaluated in subjects with overweight or moderate obesity and IGT or T2DM.
Study population: 1) mutation carriers without the hypertrophic phenotype (pre-clinical Hypertrophic Cardiomyopathy (HCM)) and in 2) patients with clinically overt HCM (clinical HCM). Hypothesis: Cardiac troponin release after exercise can be demonstrated in both clinical and pre-clinical HCM patients.
Comparison of Fractional Flow Reserve versus instant Wave-Free Ratio for assessment of coronary artery stenosis severity in routine practice - To compare FFR to iFR in arbitrary consecutive patients referred for percutaneous coronary intervention (PCI). - To investigate the influence of hyperemia on iFR. - To test reproducibility of iFR and FFR.
Approximately half of patients with acute chest pain, a very common reason for emergency department visits worldwide, have a cardiac cause. Two-thirds of patients with a cardiac cause are eventually diagnosed with a so-called non-ST-elevation myocardial infarction. The diagnosis of non-ST-elevation myocardial infarction is based on a combination of symptoms, electrocardiographic changes, and increased serum cardiac specific biomarkers (high-sensitive troponin T). Although being very sensitive of myocardial injury, increased high-sensitive troponin T levels are not specific for myocardial infarction. Invasive coronary angiography is still the reference standard for coronary imaging in suspected non-ST-elevation myocardial infarction. This study investigates whether non-invasive imaging early in the diagnostic process (computed tomography angiography (CTA) or cardiovascular magnetic resonance imaging (CMR)) can prevent unnecessary invasive coronary angiography. For this, patients will be randomly assigned to either one of three strategies: 1) routine clinical care and computed tomography angiography early in the diagnostic process, 2) routine clinical care and cardiovascular magnetic resonance imaging early in the diagnostic process, or 3) routine clinical care without non-invasive imaging early in the diagnostic process.
Increased postprandial lipemia may increase the risk for cardiovascular diseases. An important mechanistic link between lipemia following a high-fat meal and adverse cardiovascular events is lipid-mediated endothelial activation. Therefore, it is important to identify nutrients that can neutralize this acute vascular disturbance. The investigators hypothesize that beetroot juice, a food rich in inorganic nitrate, could improve vascular activity during the postprandial phase.
Plant sterols and stanols (also called phytosterols and phytostanols) are structurally related to cholesterol, but absorbed to a much lesser extent. Due to this structural similarity, plant sterols and stanols inhibit intestinal cholesterol absorption and lower serum LDL cholesterol concentrations by about 10% at daily intakes of 2.5 g. Plant sterol- and stanol-enriched food products are therefore widely available on the market to lower the risk for coronary heart disease. Plant sterols can undergo oxidation, which results in the formation of oxyphytosterols. Animal studies have now suggested that oxyphytosterols are atherogenic. Although oxyphytosterols have been identified in human serum samples, the effect of an increased intake of plant sterols on serum oxyphytosterol concentrations in humans is not known. On the other hand, plant stanols cannot be oxidized and lower not only cholesterol absorption, but also plant sterol absorption. The major objective of the present study is to examine the effects of dietary plant sterols and stanols on fasting serum concentrations of oxyphytosterols. The minor objective is to investigate the effects of these products on postprandial serum oxyphytosterol concentrations.
Almost half of the Dutch population is currently characterized by overweight and obesity. Losing weight is not the problem in obesity treatment, it is the seemingly obligatory weight regain after weight loss: the yoyo-effect. The primary objective of this study is to investigate the association between the weight-loss-induced cellular stress response and the rate of weight regain. The secondary objective is to investigate the differences in cellular stress response and weight regain after rapid and slow weight loss. To investigate this, subjects will receive meal replacements replacing either all or part of the daily meals during the intervention period. THe first group will consume 500 kcal/d diet for 5 weeks while the second group consumes a 1250 kcal/d diet for 3 months, both followed by 1 week normalization and a 2 week strict weight maintenance diet. During the 9-month follow-up period subjects will receive dietary advice according to the Dutch recommendations for healthy eating. The association between the amount of weight regain after the weight loss period and changes in adipokines, parameters of adipocyte metabolism, in vivo adipose tissue metabolism, adipocyte extracellular matrix gene expression profiles, adipocyte stress protein expression and gene polymorphisms in selected genes.
