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.
The purpose of this study is to determine whether catheter ablation is more effective than antiarrhythmic drugs in the early stages of paroxysmal atrial fibrillation. In all the patients a subcutaneous loop recorder will be implanted.
Rationale: The investigators hypothesize that a change in dietary fat quality (an increase in unsaturated fatty acids) may modulate fuel partitioning within the type 2 diabetic muscle towards less accumulation of lipid metabolites and an improved insulin sensitivity. Objective: 1. The contribution of dietary vs endogenous fat sources to lipid overflow in the circulation and to skeletal muscle lipid uptake and storage in obese insulin resistant subjects vs obese insulin sensitive controls. 2. The acute effect of meals with various fatty acid composition ((high saturated (SFA) vs polyunsaturated (PUFA) vs monounsaturated (MUFA)) on skeletal muscle lipid uptake and storage, fatty acid mediated gene expression and postprandial insulin sensitivity in obese insulin resistant subjects. Study design: single-blind randomized cross-over trial Study population: obese males (35-70 years) with or without insulin resistance Intervention: 1. 1 test meal 2. 3 test meals with a different fatty acid composition Main study parameters/endpoints: More insight whether dietary fat quality may modulate circulating lipids and skeletal muscle fatty acids handling, and may affect oxidative capacity and lipid storage in parallel to an increased insulin sensitivity.
In this prospective cohort study the investigators will assess the prevalence and incidence of a broad range of age-related co-morbidities and their (known) risk factor among HIV-patients and HIV-negative controls. HIV might cause premature onset or accelerated aging and could therefore result in an increase of age-related comorbidities when compared with controls.
The primary objective of this study is to determine whether exploring the request for help more thoroughly improves patient satisfaction in general practice (primary care).
This study is designed to evaluate the efficacy and safety of tofacitinib (CP-690,550) in patients with moderate to severe ulcerative colitis who have failed or be intolerant to one of following treatments for ulcerative colitis: oral steroids, azathiopurine/6-mercaptopurine, or anti-TNF-alpha therapy.
The current prevalence of hypertension as part of the metabolic syndrome is substantial and is increasing with the rise of obesity worldwide. Chronic elevation of sympathetic nervous system (SNS) activity has been identified as a common and key factor in disease states as obesity-related hypertension (ORH). The renal sympathetic nerves are a major contributor to the complex pathophysiology of this elevated SNS activity. Percutaneous renal denervation (PRDN), the deliberate disruption of the nerves connecting the kidneys with the central nervous system, has been shown to be an effective means of modulating elevated SNS activity. This current study is an observational feasibility study, with the aim to investigate the effect of renal denervation on changes in insulin resistance and blood pressure in patients with obesity related hypertension. The investigators will study different variables: a laboratorial set, a set of blood pressure measurements and a set of investigations in the vascular laboratory. Hypothesis - The investigators hypothesize that renal denervation has a beneficial effect on insulin resistance. - The investigators hypothesize that there will be no complications related to the device or procedure.
Imagery Rescripting (IR)is a promising treatment for PTSD in adult survivors of early, chronic, interpersonal trauma (e.g. Smucker & Dancu, 1999). So far, this protocol has not been investigated within a controlled setting with patients with PTSD following early, chronic, interpersonal trauma. The aim of the proposed study is to 1. investigate the efficacy of Imagery Rescripting and 2. check whether the efficacy of Imagery Rescripting can be improved by adding a stabilization phase (Skills training in affective and interpersonal regulation, STAIR) prior to this treatment. In a randomized controlled trial three conditions will be compared: 1. Imagery Rescripting 2. STAIR + Imagery Rescripting 3. Wait-list control
This study will evaluate the efficacy and safety of Azimilide on the incidence of cardiovascular hospitalizations, cardiovascular emergency department visits or cardiovascular death in patients with Implantable Cardioverter Defibrillators (ICDs)
Both ulcerative colitis and Crohn's colitis are associated with an increased risk of developing colorectal cancer (CRC). Although the increased risk of CRC in colitis patients is well established, several studies show that the risk varies widely between patients, depending on the presence of risk factors. Recently, several of these risk factors were implemented in the updated British guidelines for surveillance which are now used to determine surveillance intervals in our center. The new guideline recommends stratification of patients in a high, medium or low risk group depending on the presence of clinical and endoscopic risk factors and to adjust the surveillance interval accordingly. Although these guidelines provide a first step towards an individualized surveillance regimen, current data regarding risk factors for IBD (inflammatory bowel disease) -associated CRC are solely based on retrospective studies. Prospective data on the phenotype and genotype reliably predicting the risk of CRC is needed to further optimize surveillance in the future. Objectives: 1. To confirm established and identify new predictive factors for colorectal cancer in a prospective cohort of IBD patients undergoing regular surveillance. Dysplasia or colorectal cancer will be the primary outcome. 2. To provide evidence that mucosal healing results in a significant reduction of colorectal dysplasia/neoplasia in IBD patients and that this is associated with 5-ASA (5-aminosalicylic acid) or anti-TNF (tumor necrosis factor) maintenance therapy. 3. Study the expression of several tumor markers in biopsies, blood and faeces at baseline and determine whether expression of these markers can predict dysplasia or colorectal cancer development during follow-up.
This clinical study will demonstrate the accuracy of the chromosomal aberration and gene mutation markers of the AMLProfiler molecular diagnostic assay and generate clinical performance data to support a Pre-Market Approval (PMA) submission to the Food and Drug Administration for in vitro diagnostic use within the United States of America. The objective is to demonstrate the positive and negative percent agreement of each marker by comparing AMLProfiler results from multiple clinical participating sites with data generated using a laboratory developed bi-directional sequencing method generated at the molecular diagnostic reference lab. The AMLProfiler assay is a qualitative in vitro diagnostic test for the detection of AML or APL specific chromosomal aberrations (specific recurrent translocations and inversions), as well as expression of specific genetic markers in RNA extracted from bone marrow aspirates of patients with Acute Myeloid Leukemia.
