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 primary objective of this study is to verify the acceptability of the GUARDIAN system by the elderly, detected through the scale Unified Theory of Acceptance and Use of Technology (UTAUT). The GUARDIAN platform consists of two connected apps: one dedicated to the caregiver and one dedicated to the older people, plus a robot (Misty II). Misty II will live with the elderly, it will have the task of detecting his presence inside the house, reminding him of appointments, assisting him in his daily activities and diminishing the sense of loneliness. The application dedicated to the caregiver receives the data and self reports of the elderly from the robot, in order to constantly offer an updated picture of the condition of the elderly and to keep them informed about their condition and well-being.
The aim of this study is to investigate whether ANEB-001 effectively penetrates the brain and inhibits the psychotropic effects of Δ9-Tetrahydrocannabinol (THC), the main psychoactive constituent of cannabis. This randomized, placebo-controlled, double-blind study is designed as a proof-of-pharmacology and dose finding study for the antagonistic effect of ANEB-001 during a THC challenge. Results of this study will inform the future potential use of ANEB-001 as an emergency treatment for acute cannabinoid intoxication.

A prospective monocenter diagnostic accuracy study of Confocal Laser Endomicroscopy (CLE) for Bladder Cancer(BC) to assess two primary objectives: 1. The diagnostic accuracy of flexible probe-based confocal laser endomicroscopy (CLE) compared to histopathology of the resection specimen. 2. The diagnostic accuracy of CLE-based assessment of the surgical radicality of the resection bed (radical vs irradical) in comparison with histopathology of a biopsy of the resection bed. All patients with a papillary bladder tumor on cystoscopy will be included in this trial.
Catecholamine (CA) neurotransmitters, such as dopamine (DA) and noradrenaline (NA), have long been implicated playing a critical role in cognitive functions, such as working memory (WM), inhibition, learning, and decision making. Recent evidence from neurodegenerative patients and the healthy population suggested that CA also influences language processing. However, the question of what kind of influence that CA might exert on language is still open. Some previous studies have shown that CA can enhance semantic processing. In a recent study it was observed that CA agonists (i.e., methylphenidate) enhance participant's sensitivity to semantically incongruent information even when language processing was actually goal-irrelevant. On the other hand, the processing of semantically congruent information was enhanced while language processing was the goal. Moreover, consistent with some previous findings that there is a relation between participants' baseline characteristics and MPH effects, it was observed that participants with lower WM capacity benefited more from receiving methylphenidate. These results shed light on the relation between CA and language processing, but also lead to further questions, such as whether the interaction between CA and semantic processing is language-specific or mediated by the relation between CA and more general cognitive functions (e.g., WM, inhibition), and whether CA also has an influence on other aspects of language processing, such as syntactic processing. The present study aimed to further investigate the nature of the relation between CA and language processing by administrating methylphenidate (MPH) to healthy participants. MPH is an indirect CA agonist, which is the most commonly prescribed drug for attention deficit/hyperactivity disorder (ADHD). Previous studies have shown that MPH can efficiently increase the extracellular levels of CA in the brain by blocking their reuptake. Objective: The primary objectives are: 1) to further investigate the effect of CA on semantic processing. The study plans to examine whether MPH interacts with processing of sentence context constraints via its influence on cognitive control operations. 2) To investigate the effects of MPH on syntactic processing. More specifically, the study is interested in whether MPH has an influence on revising syntactically temporarily ambiguous sentences. A secondary objective is to further examine the relation between MPH effects and the baseline characteristics of individual participants. Study design: This study will use a within-subject, double-blind, placebo-controlled, randomized, crossover design. Study population: Approximately 40 healthy native Dutch speakers between 18 and 45 years old will be recruited. All subjects will have to complete one screening session and two separate testing sessions within three different days at the Donders Centre for Cognitive Neuroimaging (DCCN). Intervention: Participants will either orally receive a 20mg methylphenidate or placebo capsule in each of the two testing sessions. Methylphenidate has been approved for clinical use in the Netherlands and the drug can be administered safely without any relevant risk of serious adverse events. Main study parameters: Primary study parameters will include sentence comprehension capacity, attention and processing speed. In addition, several other measures will be included to monitor participants' baseline characteristics (e.g. working memory capacity, vocabulary size) and the general modulation effects of MPH (e.g. heart rate, blood pressure, subjective feeling). Hypotheses: Based on the previous finding that methylphenidate improves cognitive stability while it impairs flexible updating, the hypothesis is that methylphenidate will hinder participants' performance in resolving syntactic ambiguity, which requires an immediate updating and revising of an initial interpretation. This should be reflected in event-related potential (ERP) measures related to revision, namely the P600 effect is predicted to be reduced in the drug condition compared to placebo.
This study will investigate the potential benefit of scheduled natural daylight exposure to improve glucose control in type 2 diabetes (T2D) patients and to unravel molecular mechanisms underlying the effects of natural daylight on circadian clocks and (glucose) metabolism in human skeletal muscle from T2D patients. Participants will stay at our research facilities and will be exposed to natural daylight or artificial light during the daytime over 4.5 days in a randomized cross-over design. For both conditions, the evening and night will be spent under standardized dim and dark conditions.
The study will consist of 2 parts, i.e. a single ascending dose part with integrated food effect assessment and assessment of relative bioavailability (Part A), and a multiple ascending dose part (Part B). Part A will have a randomized, double-blind, placebo-controlled design. Subjects will receive single ascending doses of CFTX-1554 or placebo (as liquid formulation under fasted condition) in 7 subsequent cohorts. Drug intake under fed conditions, and as capsule under fasted conditions and under fed conditions (Periods 2 to 4), compared to liquid formulation under fasted conditions (Period 1) (1 single dose level only) will be assessed. Part B will have a randomized, double-blind, placebo-controlled design, assessing multiple ascending oral doses of CFTX-1554 or placebo in 4 subsequent cohorts.

Rationale: The most common approach to weaning infants and children is gradual reduction of ventilatory support ("traditional approach"). Alternatively, another approach to weaning is attempted with alternating periods of complete ventilatory support and graded spontaneous breathing with assistance ("sprinting approach"). Both approaches are used randomly in our unit: the decision to use which approach is dependent upon the preferences of the attending physician as described in many observational single center studies. To date, there is no data comparing the safety and efficacy of the "sprinting" approach with more traditional approaches of weaning in children. Hence, numerous issues remain unanswered, including the work-of-breathing during each approach. For this research proposal, we want to measure the work-of-breathing daily, using the traditional approach (the area under the oesophageal pressure - volume curve) and study its correlation with clinical parameters and EMG activity of the diaphragm and intercostal muscles from the moment that the patient is weaned off the ventilator. Objective: The primary objective for this study is to compare for each patient of the work-of-breathing during the "sprinting"approach and the "traditional approach.The secondary objectives for this study are to compare the oesophageal pressure rate and (PRP) and pressure time product (PTP), the PaO2/FiO2 ratio, global and regional distribution of tidal volume measured using electrical impedance tomography (EIT), phase distribution of the respiratory inductive plethysmography (RIP) signal and the EMG activity of the diaphragm and intercostal muscles between the "sprinting"and the "traditional" approach.. Study design: This is a prospective exploratory study with invasive measurements in a 20 bed tertiary paediatric intensive care facility at the Beatrix Children's Hospital/University Medical Centre Groningen. Study population: All mechanically ventilated children aged 0 to 5 years with or without lung pathology admitted to the paediatric intensive care unit are eligible for inclusion. Inclusion criteria include mechanical ventilation for at least 48 hours, weight ≥ 3 kg, sufficient respiratory drive present, deemed eligible for weaning by the attending physician, and stable haemodynamics (defined by the absence of need for increase in vaso-active drugs and/or fluid challenges at least 6 hours prior to enrolment). Exclusion criteria include mechanical ventilation less than 48 hours, not eligible for weaning (usually when there are unstable ventilator settings, defined by the need for increase of inspiratory pressures or positive end-expiratory pressure, and a FiO2 > 0.6 within 6 hours prior to enrolment), unstable haemodynamics (defined by the need for increase in vaso-ative drugs and/or fluid challenges within 6 hours prior to enrolment), leakage around the endotracheal tube > 5%, admitted to the neonatal intensive care unit, preterm birth with gestational age corrected for post-conceptional age less than 40 weeks, congenital or acquired neuromuscular disorders, congenital or acquired central nervous system disorders with depressed respiratory drive, congenital or acquired damage to the phrenic nerve, congenital or acquired paralysis of the diaphragm, use of neuromuscular blockade prior to enrolment, uncorrected congenital heart disorder, and chronic lung disease. Main study parameters/endpoints: The main study parameter is the level and time course of the patient's work-of-breathing mathematically calculated by the area under the pressure-volume curve Secondary study parameters include the level and time course of the PRP and PTP, level and time course of oxygenation (PaO2/FiO2 ratio), global and regional distribution of tidal volume, phase distribution, EMG activity of the diaphragm and intercostal muscles, heart rate, respiratory rate.. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: There are a priori no specific benefits for the patients who participate in the study.
