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.
Most patients are prescribed valproate as their first antiepileptic drug. It is unknown which is the best second-line drug when patients do not become seizure free on valproate. This has led the Dutch Epilepsy Clinics Foundation (SEIN) to start the SLICE study. Adult patients with partial and/or tonic-clonic seizures, insufficiently responding to valproate, are recruited for this study. These patients are randomized to receive one of three other drugs. Patients wil initially use this drug next to valproate. Neurologists of more than 20 general hospitals en neurologists of SEIN are participating in this study.
This is a study using Positron Emission Tomography (PET) to study the normal distribution of the PET ligand (R)-[11C]PK11195. This ligand will be used to study inflammation in the brain in several brain disorders like Alzheimer's disease and traumatic brain injury.
Excitatory amino acids may be involved in secondary neuronal damage after traumatic brain injury. The amount of microglia activation is an indirect measure of neuronal damage. Micorglia activation will be measured R)-[11C]PK11195 PET 1 week, 1 month and 6 months after brain injury.
A former study (submitted) in 32 severely asphyxiated infants participating in a randomized double blind study, in which early postnatal allopurinol or a placebo (within 4 hours after birth) was administered to reduce free radical formation and consequently reperfusion/reoxygenation injury to the newborn brain, showed an unaltered high mortality and no clinically relevant improvement in morbidity in infants treated with allopurinol. It was hypothesized that postnatal allopurinol treatment started too late to reduce reperfusion-induced free radical surge and that initiating allopurinol treatment of the fetus with (imminent) hypoxia already via the mother during labor will be more effective to reduce free radical-induced post-asphyxial brain damage.
The Dutch Prediction of Psychosis Study (DUPS) is a prospective study of predictors of the transition to psychosis in help-seeking adolescents at high risk for developing a first psychotic episode. The aim of the project is supplemented by a systematic account of the pathways to care, the disabilities and needs and the therapeutic interventions that are currently used in this population. Multi-level assessment includes behavioral and cognitive variables as well as structural brain imaging and neurophysiological data. Subjects will be followed up at regular intervals during (at least) two years to monitor the development of their (psychotic) symptoms. This will allow us to analyze the predictive validity of the variables.
This proposal is targeted at all patients with prostate cancer who are candidates for either curative surgery or curative radiotherapy in whom lymph node staging is indicated. Recently, it has been shown, that in patients with PSA <10 ng/ml and Gleason score < 7 the risk of lymph node metastases is low. Therefore, unnecessary PLND and non-invasive imaging can be avoided safely in this group. PLND is nowadays performed only in patients with intermediate or high risk for nodal metastases. Thus the subgroup of patients targeted in this study consists of patients with prostate cancer with a PSA >10 ng/ml and Gleason score > 6. - If the high sensitivity (90%) and negative predictive value (96%) of MRL can be validated in the 8 participating centres, in patients with a negative MRL invasive PLND may be avoided. - In patients with a positive MRL with enlarged nodes (larger than 8 mm) histological diagnosis may be obtained by imaged guided biopsy, and thus also in these patients avoid PLND. A limitation of image guide biopsy, however, is the 30% false negative rate. [Barentsz, Oyen, Wolf] - In patients with positive small nodes (smaller than 8 mm) the urologist may, focussed by the MRL findings of a positive node outside his “surgical field-of-view”, extend his dissection, and thus improve his accuracy. - Based on the expected higher sensitivity of MRL this technique will completely replace CT-scanning.
The purpose of this study is to provide evidence that the Refined Ventricular Pacing Algorithm leads to clinically relevant reduction (at least 50% reduction) of the incidence of ventricular pacing.
UVB phototherapy is a commonly used treatment for patients with psoriasis. Generally it is performed in the outpatient department of the hospital. The UVB irradiation itself will normally take only a few minutes, but to receive the irradiation patients have to travel to the outpatient department during working hours 2 or 3 times a week. In general it is a relatively time-consuming treatment. Objective of this study is to assess whether UVB treatment administered in the home is as equally effective as the standard outpatient UVB phototherapy. Quality of life and cost-effectiveness are also studied.
The VIAMI-trial investigates the effects of balloon angioplasty with stenting of the infarct-vessel in the early phase after acute myocardial infarction. The study concerns patients who have residual viable tissue in the infarct-area after being treated with thrombolysis. It is postulated that only patients with remaining viable tissue are at high-risk for recurrent infarction or anginal attacks and that stenting of the infarct-vessel will reduce this risk considerably.
The purpose of this study is to investigate whether noninvasive ventilation by nose mask during the night has additional benefits next to pulmonary rehabilitation in patients with severe hypercapnic COPD.
