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.
Acute microcirculatory perfusion disturbances is common in critical illness and associated with higher morbidity and mortality. Recent findings by the investigators' group showed that microcirculatory perfusion is disturbed during cardiac surgery with cardiopulmonary bypass (CPB) and remain disturbed up to 72 (seventy two) hours after surgery. A cardiopulmonary bypass is a machine which takes over heart and lung function, during the procedure. The disturbed microcirculation is associated with organ dysfunction induced by cardiac surgery using CPB, which is frequently seen (up to 42%, forty two percent) and results in a six-fold increase in mortality rate. The underlying cause of disturbed microcirculation is a higher endothelial permeability and vascular leakage and are a consequence of systemic inflammation, hemodilution (dilution of blood), hypothermia and hemolysis (breakdown of red blood cells). To gain the knowledge regarding disturbed microcirculation the investigators previously showed that hemodilution attributes to this disturbed perfusion. Hemodilution lowers colloid oncotic pressure (COP). Also, COP is affected by free hemoglobin, which increases with hemolysis and attributes to a disturbed microcirculation following CPB. This is interesting, as to the best of our knowledge, the effect of minimizing hemodilution and hemolysis during cardiac surgery on the microcirculatory perfusion has never been investigated, but could be the key factor in reducing organ dysfunction.
The goal of this prospective, observational, multicentre cohort study is to assess the trajectory of the experiences (both positive and negative) and health-related quality of life (HRQOL) of informal caregivers of patients who start home dialysis, and compare these to experiences and HRQOL of informal caregivers of patients who start in-centre hemodialysis. The investigators hypothesise that informal caregivers of home dialysis patients experience more positive experiences, but also more negative experiences, and still have better HRQoL, compared with caregivers of in-centre HD patients. Participants will fill in five different validated questionnaires and questions on required support. Participants are asked to fill in the questionnaires after inclusion (i.e., start of dialysis), and at 6 and 12 months after start dialysis.
The goal of this study is to determine the feasibility of CEA assessments at home using (automated) capillary sampling in patients in the follow-up after treatment for colorectal cancer. The main questions it aims to answer are: - To determine the success rate of capillary sampling at home by the patient - To assess reliability and satisfaction of (automated) capillary CEA measurements Participants will be asked to perform automated capillary sampling and lancet capillary sampling at home twice after regular check-up visits in the hospital, with an interval of 3-6 months in between. During this hospital visit, a CEA measurement in blood sampled by venipuncture will be performed to act as a reference for the CEA measurements in (automated) capillary blood to be sampled at home. Reliability of CEA measurements will be assessed for automated capillary and lancet capillary sampling compared to venipuncture. Satisfaction in terms of patient reported outcomes (pain, burden, ease of use, and preference) will be evaluated.
The study primarily aims at evaluating health-related quality of life after radiotherapy for prostate cancer, using modern hypofractionated radiotherapy schedules. Study design is a prospective observational cohort study. All patients give written informed consent and fill out online validated questionnaires before, during, and after radiotherapy (yearly) up to 5 years post-treatment.
An exploratory, pre-market, open, prospective, interventional, clinical investigation at a limited number of centers for proof of concept of a new catheter. In this proof of concept investigation, subjects experienced in using transanal irrigation (TAI) with a balloon catheter will be using study catheters at two occasions to primarily study if the catheter will stay in place during the water instillation when performing TAI. Each subject will be followed during approximately one week, depending on the usual time between their TAI.
The primary purpose of this study is to characterize the pharmacokinetics and pharmacodynamics of treatment with ravulizumab intravenous infusion in pediatric participants with gMG.
The goal of this clinical trial is to study the effects of Flow Controlled Ventilation (FCV) following conventional mechanical ventilation (Pressure or Volume Controlled Ventilation) in postcardiac surgery ICU-patients to allow for future power calculations and to obtain experience with FCV. The main questions it aims to answer are: - What is the effect of FCV on the lung volume measured by Electrical Impedance Tomography (EIT)? - What is the effect of FCV on the minute volume? - What is the effect of FCV on the mechanical power and dissipated energy? Participants will be ventilated with PCV at baseline and then switched to FCV for 90 minutes while the lung volume, minute volume and mechanical power and dissipated energy levels are measured.
Researchers are looking for a better way to treat people with atrial fibrillation and prevent stroke or systemic embolism (blood clots travelling through the blood stream to plug another vessel). Atrial fibrillation is a condition of having irregular and often rapid heartbeat. It can lead to the formation of blood clots in the heart which can travel through the blood stream to plug another vessel, and like this lead to serious and life-threatening conditions, such as a stroke. A stroke occurs because the brain tissue beyond the blockage no longer receives nutrients and oxygen so that brain cells die. As strokes arising from atrial fibrillation can involve extensive areas of the brain, it is important to prevent them. Blood clots are formed in a process known as coagulation. Medications are already available to prevent the formation of blood clots. When taken by mouth (orally), they are known as oral anticoagulants (OACs) including apixaban. OACs decrease the risk of the above-mentioned serious and life-threatening conditions. The main side effect of OACs is an increase of the risk of bleeding. The study treatment asundexian is a new type of anticoagulant currently under development to provide further treatment options. Asundexian aims to further improve the standard of care with regard to the risk of bleeding. The main purpose of this study is to collect more data about how well asundexian works to prevent stroke and systemic embolism and how safe it is compared to apixaban in people with atrial fibrillation and at high risk for stroke. To see how well the study treatment asundexian works researchers compare: - how long asundexian works well and - how long apixaban works well after the start of the treatment. Working well means that the treatments can prevent the following from happening: - stroke and/or - systemic embolism. The study will keep collecting data until a certain number of strokes or embolisms happen in the study. To see how safe asundexian is, the researchers will compare how often major bleedings occur after taking the study treatments asundexian and apixaban, respectively. Major bleedings are bleedings that have a serious or even life-threatening impact on a person's health. The study participants will be randomly (by chance) assigned to 1 of 2 treatment groups, A and B. Dependent on the treatment group, the participants will either take the study treatment asundexian by mouth once a day or apixaban by mouth twice a day for approximately 9 - 33 months. Each participant will be in the study for approximately 9 - 34 months. There will be visits to the study site every 3 to 6 months and up to 7 phone calls. Those participants who do not want or are unable to have visits to the study site may join the study remotely in selected locations. The location name contains the abbreviation - DCT in such cases. During the study, the study team will: - take blood samples - do physical examinations - examine heart health using an electrocardiogram (ECG) - check vital signs such as blood pressure and heart rate - do pregnancy tests - ask the participants questions about their quality of life - ask the participants questions about how they are feeling and what adverse events they are having. An adverse event is any medical problem that a participant has during a study. Doctors keep track of all adverse events that happen in studies, even if they do not think the adverse events might be related to the study treatments.
The investigators hypothesized that Macrovascular Flow imaging could contribute to 2D power Doppler and 3D power Doppler in depicting fibroid vascularity. However, data concerning the feasibility and reproducibility of Macrovascular Flow imaging is lacking. Therefore the purpose of our study was to determine 1) the reproducibility of Macrovascular Flow imaging, 2) its correlation with 2D and 3D power Doppler, and 3) penetration depth, in order to investigate the added value for daily clinical practice.
In the Netherlands, more than 600 thousand people have asthma. About half of these people have insufficient asthma control. This has a negative effect on their health and use of care. Insufficient knowledge about asthma and proper medication use, low self-confidence in managing asthma, and low compliance contribute to this problem. AstmaKompas is an eHealth application for asthma patients focused on self-monitoring and self-management. Astmakompas also connects patients with their healthcare professionals, among other things by giving healthcare professionals more insight into their patients' disease progression, enabling them to provide timely(er) support. In this study, AstmaKompas will be deployed and evaluated in 2 hospitals. Through questionnaires and interviews, insight will be gained into the experiences of patients and healthcare professionals with AstmaKompas. Potential effects on health outcomes and healthcare utilization will also be identified.
