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.
COVID-19, caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, has a devastating effect on human lives, including over 6.6 million death as of November 2022. Furthermore, many individuals continue to experience persisting sequelae after the initial infection. Little is known about the impact of undergoing COVID-19 hospitalisation. Hence, the investigators propose an observational longitudinal study in a cohort of COVID-19 survivors after hospital discharge, to examine their perspectives on their health, health-related quality of life, and persistence of common COVID-19 symptoms, such as fatigue, dyspnoea and anxiety. Potential influencing socio-demographic and biological factors will additionally assessed.

Amongst psychiatric illnesses, eating disorders (EDs) are notoriously difficult to treat and have a high mortality rate. The average duration of an ED is 6 years and for a majority of ED patients, the disorder will become chronic. Comorbid personality pathology such as negative core beliefs and early maladaptive schemas (EMS) are strongly related to ED severity and chronicity. Enhanced cognitive-behavioural therapy for eating disorders (CBT-E) is used as the first line transdiagnostic treatment for EDs. However, CBT-E is mainly symptom-focused and does not tap into these underlying core beliefs and EMS. Given the limited treatment effects of existing ED treatments, and the importance of comorbid personality pathology, there is an urgent need to examine more effective treatments for EDs. Group-schematherapy (GST) overcomes the limitations of CBT-E and preliminary results for treatment-resistant EDs are promising. However, robust evidence regarding the clinical and cost-effectiveness of GST for patients that do not benefit from CBT-E is not yet available. The central aim of this project is to investigate the clinical and cost-effectiveness of GST for EDs in patients with comorbid personality pathology, who do not show a clinically significant response in the first phase of CBT-E. This is relevant and important as studies examining the effectiveness of GST for EDs are scarce. This project is a joint research initiative of three academic centers (Dutch Universities), four large nation-wide mental health organizations, and two foundations for client empowerment and participation. Eligible patients will be randomized to either GST or continuation of their CBT-E treatment after failing to show a significant treatment response in the first phase of CBT-E. Based on encouraging findings from previous studies and our own pilot data, a statistically and clinically significant better outcome in terms of ED symptoms, negative core beliefs, EMS, schema modes, and quality of life is expected in the GST group compared to the CBT-E group. GST is also expected to be more cost-effective compared to CBT-E as GST may in the long run prevent chronicity in terms of long treatment trajectories and delayed recovery. Finally, with the proviso of good results for GST, we will disseminate and implement GST in the standard of care for EDs. This project thereby has great potential to improve clinical and cost-effectiveness of treatment for chronic EDs.
This study aims to investigate the lesion characteristics after pulmonary vein isolation using pulsed-field ablation in patients with atrial fibrillation and a common of the left pulmonary veins. The main question it aims to answer is: In which percentage of the patients will pulsed field ablation result in successful isolation of the left common ostium? Nineteen patients will be prospectively included in OLVG. All patients will be treated with pulsed-field ablation (routine care). After the ablation procedure, an electro-anatomical map will be created using the ablation catheter and a mapping system. This map will display the left atrium and the lesion in detail. After the procedure, three experienced operators are asked to draw a line around the LCO in the anatomical map where they would have ablated if conventional radiofrequency ablation was used. The distance between the drawn line and the ablation lesion will be measured at three predefined points. The lesion is considered successful if the mean distance is within ±10mm at all measurement points.

The purpose of this study is to evaluate change in geographic atrophy (GA) lesion growth of eyes treated with JNJ-81201887 compared to sham control.
Anastomotic leakage is a severe complication that can arise following a colorectal resection. It impairs both the short- and long-term outcomes, and negatively influences cancer recurrence rates. Its detrimental effects resound in healthcare costs of a patient after anastomotic leakage, €71,978, versus patients with an uncomplicated course, €17,647. Despite multiple innovations within the field of colorectal surgery, the incidence of colorectal anastomotic leakage did not reduce in the past decade. Mitigation strategies such as prehabilitation, intraoperative optimization, selective bowel decontamination, and reconstruction techniques are promising but do not completely eliminate the risk of leakage. The only true prevention of colorectal anastomotic leakage is the omission of an anastomosis and implies an ostomy, which in itself has a negative impact on the quality of life. A stoma is associated with stoma-related morbidity and should, therefore, be avoided in patients who do not need it. Predicting anastomotic leakage intra-operatively, just before the construction of the anastomosis, may offer a solution. A stoma will then only be constructed in those at high risk of anastomotic leakage. Currently, there are prediction models for anastomotic leakage based on conventional multivariate logistic regression analysis, however, these are not useful for clinical practice due to suboptimal results. Machine learning algorithms, on the other hand, take well into account the multifactorial nature of complications and might thus be able to predict anastomotic leakage more accurately. The machine learning model we created proved to be well capable of making accurate predictions. This model was developed based on a database containing both pre- and intra-operative data from 2,483 patients. Before these models can be used in daily practice, external validation is essential. Our models should be tested on unseen data from patients treated in centers that were not previously involved in the database that was used to train the model in order to achieve high reproducibility. Our hypothesis is that with our model, we can accurately predict anastomotic leakage intra-operatively during colorectal surgery.
This study is designed as a long-term extension to Study APL2-C3G-310, and is being conducted to establish the long-term safety and efficacy of pegcetacoplan in patients with C3 glomerulopathy (C3G) or immune-complex membranoproliferative glomerulonephritis (IC-MPGN).
Consumers are increasingly encouraged to consume more plant-based foods and lower their consumption of foods from animal origin. This shift is driven by environmental and health factors. However, the consequences of such a transition on muscle mass still remains to be explored. This is of particular importance in the older population, where the age-related reduction in muscle mass and strength is highly prevalent. Adequate dietary intake, specifically protein intake, is a well-known strategy in promoting muscle mass in older adults. Plant-based foods are currently considered to be inferior to animal-based foods in their protein quality, and are therefore considered to be suboptimal for the maintenance of muscle mass at an older age. On the other hand, combining plant-based foods may improve the protein quality and thereby the anabolic properties of a vegan meal. Evidence regarding the anabolic properties of vegan diets in older adults is scarce. As such, the current study aims to assess 1) the effects of a 12-week self-composed vegan diet in comparison to an omnivorous diet on thigh muscle volume (TMV) in community-dwelling older adults and 2) the effect of a 12-week self-composed vegan diet combined with twice-weekly resistance exercise (RE) on TMV in comparison to a self-composed vegan diet without resistance exercise in community-dwelling older adults.
The goal of this randomized controlled trial is to identify the effects of percutaneous interventions for branch PA stenosis on exercise capacity in patients with d-TGA, ToF and TA. The main question[s] it aims to answer are: The primary study objective is to identify the effects of percutaneous interventions for branch PA stenosis on exercise capacity in patients with d-TGA, ToF and TA. The secondary objectives are 1) to assess the effects of percutaneous interventions for branch PA stenosis on RV function and 2) to define early markers for RV function and adaptation to improve timing of these interventions. Participants will undergo the same series of examinations at baseline and approximately 6 months follow-up (within 6 week time-range) as part of standard care: conventional transthoracic echocardiogram (TTE), cardiopulmonary exercise testing (CPET) and conventional Cardiac Magnetic Resonance (CMR) including a low dose dobutamine stress MRI to assess RV functional reserve. The low dose dobutamine stress MRI will be performed in the interventional group from the UMC Utrecht/WKZ and Erasmus MC because the LUMC and AUMC do not have a suitable infrastructure for the low dose dobutamine stress MRI and this cannot be achieved throughout the duration of this study. The baseline CMR in the interventional group will be performed as close as possible prior to the intervention but maximal 4 weeks prior to the intervention. In addition, the intervention group will undergo standard RV pressure measurements during the intervention. Quality of life (QoL) questionnaires will be obtained at baseline and 2 weeks post intervention (intervention group) or a similar time range in the control group, which is based on experts opinion. TTE, CPET and conventional CMR will be performed within 2-4 years follow-up to assess the long-term effects of percutaneous PA interventions. Researchers will compare the difference in VO2 max (% predicted) between the interventional group (TGA, ToF or TA patients with a class II indication for a PA intervention who will undergo a percutaneous intervention for a PA stenosis) and the control group (TGA, ToF or TA patients with a class II indication for a PA intervention who will undergo conservative management)
