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.
Background and aims: A gold standard diagnostic test to diagnose chronic mesenteric ischemia is currently lacking. Isotope labelled-butyrate and glucose breath testing could theoretically quantify mucosal oxygen consumption and thereby detect ischemia, since oxygen is needed to absorb and metabolize butyrate and glucose, and distinguish aerobic/anaerobic intestinal epithelial metabolism. Here we aim to test this notion and compare results to conventional biomarkers. Methods: Healthy volunteers were randomized into two control groups and two intervention groups, each consisting of five volunteers receiving either oral 13C -butyrate or 13C -glucose. The control groups performed breath tests without any physical exercise. The intervention groups performed a 30 minutes standardized bicycle exercise test, which has been proven to elicit mesenteric ischemia. Breath samples of expired 13CO2 were collected during a period of 4 hours and results were contrasted to measurements of biomarkers in peripheral blood.
The impact of aortoiliac stenosis on kidney transplant patients remains unclear. This study aims to investigate the safety and efficacy of kidney transplantation in patients with aortoiliac stenosis.
In case of surgical procedures in the head and neck region, MRI in combination with CT of the bone is often the standard modality to visualise bony landmarks for planning, navigation and risk assessment. An important downside of a CT scan is the associated radiation exposure, especially in children. An additional downside is the sedation or general anaesthesia needed for both the MRI and CT scan session in very young children. These downsides could be removed if the CT scan can be substituted by an MRI sequence that can provide the same information as CT. This project aims to determine the feasibility of recreating CT like images of the craniofacial bones from MRI images using machine learning techniques.
The impact of donor and recipient gender combination on kidney transplant outcomes has been reported in several studies. The results vary greatly due to different factors, such as minor histocompatibility antigens, nephron overload, sex hormones, etc. Despite advancements in clinical practice, no large-scale studies exploring this question in living donor kidney transplantation have been conducted in the subsequent two decades. Our study aims to address this research gap and provide updated information on outcomes in relation to the gender combination following living donor kidney transplantation.
A fundamental aspect of daily life decision-making involves the evaluation of costs and benefits. Neural systems underlying cost-benefit evaluation have been extensively examined, but the specific role of different neurotransmitters remains unclear. Numerous studies suggest that both dopamine (DA) and norepinephrine (NE) are closely related to reinforcement learning, guided exploration/exploitation, and behavioural energisation, although no studies to date have investigated the distinct role of DA and NE on cost-benefit decision-making and learning in human subjects.
To establish the safety and feasibility of interventional x-ray and scintigraphy imaging during the pre-treatment procedure of hepatic radioembolization
This trial compares the relative bioavailability of apraglutide in dual-chamber syringes (DCS) versus the reference formulation apraglutide in vials.
The primary objective is to assess the effect of apraglutide on gastric emptying of liquids in healthy subjects, as measured by the PK of acetaminophen mixed with a liquid meal.
Monitoring the respiratory rate is important during procedural sedation. Several methods of measuring the respiratory rate are available, but most are unreliable and the most reliable method (capnography) is not available during the use of High Flow Nasal Cannula (HFNC) oxygen. We hypothesize that measuring the pressure variation in the HFNC-circuit is a reliable method of measuring the respiratory rate. An experimental study, using healthy volunteers that will breath in three guided respiratory rates, compares the measurements of respiratory rate by the pressure variation in the HFNC circuit with measurements of respiratory rate by an ECG-derived method and a manual count by an physician. A secondary outcome will be the ability to measure the size of pressure difference, in order to determine its feasiblity to use it as a surrogate for tidal volume or respiratory effort.
The goal of this observational study is to investigate the role fibroblasts play in the persistent respiratory complaints after a COVID-19 infection. Fibroblasts are involved in tissue remodeling and repair by creating scar-tissue (fibrosis) after tissue damage has occurred. The hypothesis is that this process of fibrosis is ongoing in patients with persistent complaints. To evaluate the roll of fibroblasts a new type of scan is used that is capable of imaging active fibroblasts, a 68Ga-FAPI PET/CT scan.
