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.
This study will evaluate whether the combination of sacituzumab govitecan (SG) and bevacizumab will result in shrinkage of brain metastases from patients with non-squamous non-small cell lung cancer (NSCLC), with disease progression on chemotherapy and immunotherapy.
In patients with angina pectoris undergoing a coronary angiography (CAG) up to 40% do not have obstructive coronary artery disease (CAD). The majority of patients with no obstructive CAD are women with a frequency of up to 70% compared to 50% in men. These patients are diagnosed as having angina and non-obstructive coronary arteries (ANOCA). There are two endotypes of ANOCA. The first endotype is microvascular angina (MVA) caused by a combination of structural microcirculatory remodelling and functional arteriolar dysregulation, also called coronary microvascular dysfunction (CMD). The second endotype is vasospastic angina (VSA) caused by epicardial coronary artery spasm that occurs when a hyper-reactive epicardial coronary segment is exposed to a vasoconstrictor stimulus. Both endotypes of ANOCA are associated with significantly greater one-year risk of myocardial infarction (MI) and all-cause mortality, have a significantly impaired quality of life and have a high health care resource utilisation. The current treatment for ANOCA consists of three aspects. The first aspect is managing lifestyle factors such as weight management, smoking cessation and exercise. The second aspect is managing known cardiovascular risk factors such as hypertension, dyslipidaemia and diabetes mellitus. And the third aspect is antianginal medication. In both endotypes ACE inhibitors or angiotensin II receptor blockers should be considered. In MVA the antianginal medication that can be used are betablocker, calcium channel blocker, nicorandil, ranolazine, ivabradine and/or trimetazidine. In VSA calcium channel blocker, long-acting nitrate and/or nicorandil can be initiated as antianginal therapy. Despite these treatment option approximately 25% of ANOCA patients have refractory angina symptoms. A possible treatment modality for ANOCA patients with refractory angina pectoris is spinal cord stimulation (SCS) or transcutaneous electrical nerve stimulation (TENS). Previous research (in patients with cardiac syndrome X) has shown that SCS improves time until angina and ischaemia, significantly less angina and an improvement in quality of life. These findings suggest that SCS and/or TENS could be a possible treatment modality for patients with ANOCA. The aim of this pilot study is to investigate whether treatment with TENS during a one month period leads to a significant reduction of angina pectoris and therefore a significant improvement in quality of life in patients with proven ANOCA, encompassing both endotypes (MVA and VSA).
Hypertrophic cardiomyopathy (HCM) is a genetic disorder characterized by asymmetric hypertrophy of the heart in absence of loading conditions like hypertension. The genetic mutation underlying HCM sets in motion a cascade of functional and metabolic changes ultimately leading to disease. HCM patients often have microvascular dysfunction and myocardial perfusion deficits, of which the aetiology has not been elucidated. Whether these changes are secondary to remodelling or primarily caused by endothelial dysfunction is unclear. As the pathomechanism of HCM is thought to be a cascade of changes, it is important to gain more insight in the perfusion and endothelial function changes throughout different stages of disease: no phenotype, mild phenotype, and advanced HCM phenotype. In this study we aim to investigate these changes in the two most common genetic mutations.
The goal of this observational cohort study is to identify and predict parameters for successful testicular sperm extraction (TESE) procedures or semen cryopreservation more accurately and to evaluate the decision making process and the experience of postponing or temporarily discontinuing puberty suppression to undergo successful fertility preservation. in transfeminine (assigned male at birth) adolescents. The main question[s] it aims to answer are: - What is the optimal timing for fertility preservation before the start or after temporarily discontinuing puberty suppression puberty suppression - How do transfeminine adolescents and their parents experience the decision making process of fertility preservation - how do transfeminine adolescents and their parents experienced postponing or temporarily discontinuing puberty suppression to undergo successful fertility preservation? Participants will be asked to use their medical data, answer a questionnaire or participate in a (online) interview.
The goal of this observational study is to assess food intake in hospitalized patients. The present study will evaluate the impact of a novel in-hospital meal concept (three channel food concept) on total energy and protein intake, macronutrient distribution, and patient appreciation Food intake will be assessed (as part of usual care) by weighing all leftovers (e.g. food that patients did not consume).
G3P-01 is an investigational pectin extracted, enriched and purified from commercial squash puree intended for human consumption. Pectins are an important constituent of fruits and vegetables, and health benefits are attributed to its intake. Some of the health benefits of pectins are attributed to inhibition of galectin-3. This study investigates if 30-days of G3P-01 intake in individuals with elevated galectin-3 induces biomarker changes that can be attributed to target engagement. Participants will be randomized into four groups (placebo, 100mg, 250mg and 1000mg G3P-01).
Heavy menstrual bleeding (HMB) affects approximately one in four women and imposes considerable social, emotional, physical and economic burdens. Despite various treatment options available, endometrial ablation (Novasure) has emerged as a promising solution, with documented efficacy and high patient satisfaction rates. In the context of peri- and postoperative pain, research has reported that patients experienced less pain during the Novasure endometrial ablation procedure in comparison with two other systems. Moreover, postoperative pain rates were lower in patients treated with Novasure compared to another endometrial ablation device (ThermaChoice system). Nonetheless, it remains unclear how patients in detail experience the Novasure treatment. It is not clear which factors contribute to either a positive or a negative experience. Moreover, it is unknown if women wish more education before the procedure in order to feel well prepared for the procedure and possible post-procedural symptoms. Therefore, we want to investigate how women with heavy menstrual bleeding experience education about endometrial ablation (Novasure) treatment, the procedure itself and short-term care after treatment. In this randomized-controlled pilot study, the aim is : 1. To determine if educational videos that show experiences from women with HMB that were treated with Novasure endometrial ablation affect preoperative anxiety. 2. To assess if educational videos have an effect on preoperative need for information 3. To explore Novasure pre-, peri- and postoperative patient experiences 4. To define positive and negative factors related to Novasure endometrial ablation 5. To gain insight in factors that could improve patient satisfaction before, during and after Novasure endometrial ablation and to evaluate the educational videos.
Objective: to gain insight in the pathogenesis, to identify biomarkers to recognize patients at risk for proliferative SCR and to investigate its associations with clinical and laboratory characteristics. Endpoints: The investigators will determine the difference in the above named parameters between patients with and without PSCR Study design: This case control study will include adult sickle cell disease patients with the HbSS or HbSC genotype. For both genotypes, 20 patients without sickle cell retinopathy (SCR) and 20 patients with PSCR will be included, resulting in a total of 80 patients. Venous blood samples and retinal imaging scans will be collected for each included patient.
Most digestive cancers show (over)expression of the tumour marker carcinoembryonic antigen (CEA). Therefore, interest in CEA-targeting tracers has increased over the past years. CEA-targeting tracers can be used for preoperative, intra-operative and postoperative imaging purposes. This study focusses on both preoperative and intraoperative multimodal imaging and image-guided surgery in patients with rectal cancer or pancreatic cancer.
Disturbances in brain insulin-sensitivity are not only observed in obesity and type 2 diabetes (T2D), but also during brain aging and in dementia. Ketone monoester supplements may improve brain insulin-sensitivity, which can be quantified by measuring the gray-matter cerebral blood flow (CBF) response to intranasally administered insulin. We hypothesize that acute ketone monoester supplementation increases (regional) brain vascular function and insulin-sensitivity thereby improving cognitive performance and appetite control. The primary objective is to evaluate in older men the acute effect of ketone monoester supplementation on (regional) brain vascular function and insulin-sensitivity, as quantified by the non-invasive gold standard magnetic resonance imaging (MRI)-perfusion method Arterial Spin Labelling (ASL). The CBF response to intranasal insulin is a robust and sensitive physiological marker of brain insulin-sensitivity. Secondary objectives are to investigate effects on cognitive performance as assessed with a neuropsychological test battery, and appetite control as quantified by functional MRI (fMRI) with visual food cues.
