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 aim of this study is to assess the effect of a simple intervention (a combination of education and feedback) on Antinuclear Antibody (ANA) testing. This aim was chosen because of the known overuse of many laboratory tests, of which ANA testing is one. As overuse of ANA tests can have negative consequences (both for patients and society), the investigators designed an intervention to see how this would influence Antinuclear Antibody testing by rheumatologists.
In this study, Dutch gastroenterologists who are certified for performing colonoscopies on FIT-positive patients in the Dutch population screening program are trained in optical diagnosis with validated methods. After this training, an ex- and in-vivo test phase leads to "accreditation" and endoscopists will be observed in their optical diagnosis for 1 year. During this year, half of the endoscopists will be randomized towards 3-monthly feedback and the other half will receive feedback on their results after 1 year. The endoscopic prediction of endoscopists on polyp histology will be compared to histopathological outcome.
The aim of this study is to explore the effects of substitution in out-of-hours primary care. In consecutive stages an extra General Practitioner (GP) is substituted by a Nurse Practitioner (NP) aiming at replacing 3 out of 4 GPs by NPs. Effects are measured in terms of feasibility and cost-efficiency.
This is a control registry to the E-FIRM registry to track conventional atrial fibrillation (AF) procedures in terms of clinical usage, handling, and the safety and effectiveness for the treatment of symptomatic atrial fibrillation. Conventional AF ablation is defined as pulmonary vein isolation (PVI) and any additional ablation for AF according to the standard routine of the center. Data items will be collected, if available, consistent and applicable with routine and standard clinical care at each participating site.
The purpose of this study is to evaluate the efficacy and safety of ustekinumab as intravenous (IV: into the vein) infusion in induction study in participants with moderately to severely active Ulcerative Colitis (UC) and as subcutaneous (SC) administration in maintenance study in participants with moderately to severely active Ulcerative Colitis (UC) who have demonstrated a clinical response to Induction treatment with IV ustekinumab.
Patients with advanced oesophagogastric cancer (OCG) have a very poor prognosis. After progression on first line therapy, second line chemotherapy with paclitaxel and a VEGF-R2 targeting antibody has a proven benefit on survival. However, no data are available on the combination of paclitaxel with kinase inhibitors in advanced OGC. Here the investigators propose a Phase 1b study to assess the tolerability of regorafenib (an oral multi kinase inhibitor) in combination with paclitaxel and to assess the uptake of paclitaxel in OCG metastasis.
The hypothesis behind this study is that there is a proportion of patients considered high or intermediate risk for surgery, but relatively low risk for TAVI, which can be discharged early after the procedure (within the first 2-3 days) without additional risks. Therefore, when performed in safety, an early discharge may cut periprocedural TAVI costs significantly.
The purpose of this "first-in-human" study of PDR001 was to characterize the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD) and antitumor activity of PDR001 administered i.v. as a single agent to adult patients with solid tumors. By blocking the interaction between PD-1 and its ligands, PD-L1 and PD-L2, PDR001 inhibits the PD-1 immune checkpoint, resulting in activation of an antitumor immune response by activating effector T-cells and inhibiting regulatory T-cells.
The purpose of this study was to demonstrate efficacy including effect on inhibition of progression of structural damage, safety and tolerability up to 2 years with primary focus at Week 16 (week 24 for structural damage), to support the use of secukinumab pre-filled syringe (PFS) by subcutaneous (s.c.) self-administration with or without loading regimen in subjects with active Psoriatic Arthritis (PsA) despite current or previous NSAID, DMARD therapy and/or previous anti-TNFα therapy. Long term efficacy up to 2 years was based on signs and symptoms of joint/bone structure preservation (X-ray) and improvement in physical function measured by Health Assessment Questionnaire - Disability Index (HAQ-DI©), as well as skin and nail improvement for psoriasis signs.
Delirium is a common disorder in hospitalized patients, nevertheless it is poorly recognized by physicians and nurses, even when screening instruments are used. Electroencephalography (EEG) appears to be a sensitive tool for the diagnosis of delirium. However, standard EEG recording with 25 electrodes is labor intensive. We have previously showed that a brief EEG registration with three electrodes and automatic processing can distinguish patients with delirium from patients without delirium very well. However, these findings need to be validated in an unselected population. The primary objective of this validation study is to investigate the sensitivity, specificity, and predictive values of the EEG-based delirium monitor (including three electrodes and a reference electrode) compared to delirium quantification in frail elderly patients after surgery. In an international multicenter study, 154 frail elderly patients will be included who will undergo elective surgery and are expected to remain admitted for at least two postoperative days. Patients are excluded if communication is not possible or admitted for neurological surgery. A five minute EEG registration with the delirium monitor with four electrodes will be performed prior surgery and three consecutive days after surgery or until discharge. Within one hour of the EEG recording, the delirium assessment will be performed and recorded on video, which will be evaluated by delirium experts. The relative delta power (calculated from one minute of artifact-free EEG segment) will be compared with the conclusion of the delirium experts.
