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 the optimal screening intervals and cost-effectiveness of population-based vision screening in preverbal children in the Netherlands.
17p-/p53-mutated chronic lymphocytic leukemia (CLL) is an orphan disease, accounting for approximately 5% of newly diagnosed CLL. This subgroup of patients has a very poor outcome after chemoimmunotherapy. Allogeneic HCT may change the poor prognosis. In a retrospective EBMT-analysis on 44 patients with advanced 17p-CLL 2-year progression-free survival was 45% (95% CI, 30% to 60%) after allogeneic HCT (Allogeneic hematopoietic stem-cell transplantation for chronic lymphocytic leukemia with 17p deletion: a retrospective European Group for Blood and Marrow Transplantation analysis. J Clin Oncol, 2008, 26, 5094-5100). Referring to these favorable results and small additional series, patients with 17p-CLL requiring therapy are considered to have an indication for allogeneic transplantation by many CLL study groups. Several CLL study groups recommend allogeneic HCT in 17p-CLL as part of the first- or second line treatment. The aim is to collect additional evidence on allogeneic HCT in 17p-/p53-mutated CLL in first or second remission by a non-interventional prospective study. Patients shall be registered prior to HCT at the Leiden Office in order to rule out a reporting bias after transplantation.
The introduction of drug-eluting stents (DES) in the treatment of coronary artery disease has led to a significant reduction in morbidity. However, the first generation of these devices had no positive impact on the mortality after PCI (compared to bare metal stents), which was greatly attributed to a somewhat increased incidence of late and very late stent thrombosis. Concerns about the role of durable polymers as a potential trigger of inflammation and finally adverse events also led to the development of DES with biodegradable coatings, which leave after degradation of the coating only a bare metal stent in the vessel wall that does not induce an inflammatory response. While such biodegradable polymer DES are increasingly used in clinical practice, there is no data available from head-to-head comparisons between biodegradable and contemporary third generation durable polymer DES.
Despite many years of research, an incomprehensible amount of scientific efforts worldwide and billions of dollars invested, no effective therapy resulting in major neurological or functional recovery is available to date for traumatic spinal cord injury (tSCI). Although there is increasing experimental evidence from animal models that surgical decompression of the spinal cord improves recovery after tSCI, clinical studies have not shown conclusive data yet. The main explanations for this lack of convincing evidence are relatively small sample sizes in previous studies, their predominantly retrospective nature, suboptimal measurement methods for the assessment of neurological deficits, and inappropriate recording and documentation of potential confounding factors.
A study for patients with abnormal heart rhythm (atrial fibrillation) who need to undergo cardioversion (procedure to restore normal heart rhythm). The study will compare patients assigned randomly (like flipping a coin) to either Rivaroxaban or vitamin K antagonist (VKA). The study will measure common medical outcomes for this type of patient such as bleeding and stroke.
The intent of this study is to compare the performance of the CLA-EUS versus the FV-EUS in the performance of EUS-FNA of patients with solid lesions of the GI tract and of adjacent organs, with the aim of establishing for which lesions and from which location the capability of the FV-EUS will be superior, equal or, inferior to the CLA-EUS
The objective of this study is to assess the atrial fibrillation (AF) episode detection when using the SJM(St. Jude Medical) Confirm ICM (Implantable Cardiac Monitor).
The purpose of this study is to evaluate whether simtuzumab (GS-6624) is effective at preventing the progression of liver fibrosis in adults with primary sclerosing cholangitis (PSC).
In this study, the beneficial effect of a nutrient enriched dairy product will be investigated on vitamin K-status. To achive this benefit, the study product contains extra vitamin K2. In addition, extra dairy minerals have been added to the study product that may support general health.
Introduction Cardiovascular disease is the leading cause of death in the Western world. The main cause for cardiovascular events is the development of atherosclerosis in the coronary arteries. In more than 70% of cases, myocardial infarctions are caused by atherosclerotic plaque rupture, which results in subsequent formation of an occluding thrombus. Plaques that have a high risk of rupture are called vulnerable plaques. Cardiovascular imaging provides a complementary diagnostic approach in the assessment of cardiovascular risk in patients. However, the lack of biological detection possibilities of current imaging technologies limits their predictive value. For instance, multi detector computed tomography (MDCT) is an excellent tool to visualize coronary atherosclerosis. However, individual risk assessment is still problematic. Which of the diagnosed atherosclerotic plaques will undergo plaque rupture and lead to acute vascular events is currently hard to predict. Potentially, serum biomarkers could help identify the patient at risk. A wide variety of prognostic markers related to atherosclerosis have been identified in the past to predict for cardiovascular events. Nevertheless, their predictive value in individual patients is still limited. A difficulty in serum biomarker research is the requirement of large patient cohorts to study the relation between event rate and serum biomarker levels. The necessity to perform lengthy and costly studies, hinders the translation of novel cardiovascular serum biomarkers into the clinic. An alternative approach could be to study the correlation between levels of serum biomarkers and the presence of atherosclerosis in the coronary arteries. Study objectives Primary objective of the present analysis is to investigate the predictive value of a variety of serum biomarkers to predict atherosclerosis in the coronary tree of patients undergoing cardiac MDCT. Design and Methods Patients undergoing cardiac MDCT are eligible for the study. Excluded are patients with acute coronary syndrome, hemodynamic instability, pregnancy, severe renal insufficiency, allergy for contrast medium and inability to obtain informed consent. Permission to store the serum samples for future analysis of new prognostic markers for cardiovascular events will be acquired from the patients. Written information is send to the patient at least 1 week prior to CT. The samples will be stored coded, at the Biobank Maastricht, for a maximum duration of 15 years. Once measurements from the samples will be performed, the serum samples will be sent by the Biobank coded to the analyzing researchers, which have no access to the key file where codes are linked to the specific hospital identity number. This file will be stored by an independent researcher at the Cardiology department of the Maastricht University Medical Center. The assessment of atherosclerotic burden of the coronary tree will be performed by cardiac MDCT specialists blinded to the clinical data and serum biomarker outcome. Biomarker levels are correlated to the severity and amount of coronary artery disease as assessed by cardiac MDCT.
