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 aim of this study is to explore the effect of substituting General Practitioners (GPs) by Physician Assistants (PAs) in out-of-hours primary care. Effects are measured in terms of the implication for the care model, quality of care delivered by PAs in comparison to GPs; the complaints treated by PAs in comparison to GPs; safety, efficiency and patient satisfaction. Lastly, this study will provide insight in the changes in costs of healthcare.
Inflammatory cytokines play a pivotal role in rheumatoid arthritis (RA) and innovative non-pharmacological therapies aimed at limiting cytokine production are highly warranted. Adrenaline, a neurotransmitter of the autonomic sympathetic nervous system, attenuates cytokine production. Along these lines, endogenous modulation of sympathetic activity could limit inflammation and therefore represent a treatment modality that would empower RA patients to exert self-control over disease activity. However, both the autonomic nervous system and the inflammatory response are regarded as systems that cannot be voluntarily influenced. Nevertheless, results from two recent studies demonstrate that this is possible through techniques developed by 'iceman' Wim Hof, namely meditation, exposure to cold, and breathing exercises. Hof himself and healthy volunteers trained by him were able to voluntarily activate the sympathetic nervous system, resulting in adrenaline release and subsequent suppression of the inflammatory response during experimental human endotoxemia (a model of systemic inflammation elicited by administration of lipopolysaccharide [LPS] in healthy volunteers). Interestingly, while having been taught all three techniques, during the endotoxemia experiment the trained subjects (like Hof himself) predominantly practiced the breathing exercises consisting of two different techniques. A `hyper/hypoventilation` technique, characterized by cycles of hyperventilation followed by breath retention and a `strength ventilation` technique consisting of deep inhalations and exhalations followed by breath holding. These techniques resulted in intermittent hypoxia and cyclic shifts in acid-base balance. Based on these observations and previous studies, the investigators hypothesize that these breathing techniques account for the increased production of adrenaline and thus for the suppressed inflammatory response but it is unclear which of these two techniques is most important.
This purpose of this study is to collect vaginal microbial samples of postmenopausal women to assess the optimal conditions for cultivation and storage of the vaginal microbiota. These samples will subsequently be used to develop a high-throughput assay that mimicks the vaginal microbial community of postmenopausal women. This assay will be used to select and screen compounds that can affect the vaginal microbiota and subsequently affect related symptoms such as vaginal dryness.
SUMMARY Rationale: People with Dravet Syndrome (DS), a rare epilepsy syndrome, have a high risk of Sudden Unexpected Death in Epilepsy (SUDEP). Mouse models indicated that the responsible sodium channel mutation (SCN1A) not only alters cortical excitability but also increases the propensity to arrhythmias. Little is known yet about the prevalence of seizure-induced arrhythmias in human DS subjects. Objective: To assess the prevalence of cardiac arrhythmias in DS and to compare the prevalence of cardiac arrhythmias between DS subjects and subjects with other types of epilepsy. Study design: Observational study. Study population: Subjects with Dravet syndrome and a known pathogenic SCN1A mutation, seizure frequency ≥ 1/week (all seizure types except for absences or myoclonias), age ≥ 6 years and no signs of self-harm. Each case will be matched to two historical controls (age +/- 5 years) from the EEG databases of the participating centres. Only those controls with two or more recorded seizures will be matched to the cases. Intervention: Main study parameters/endpoints: Ictal asystole Ictal bradycardia Ictal QT-shortening/lengthening Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Participation does not carry risks. The sensor is wearable and miniaturised, thus minimising discomfort. If this nevertheless may occur, the study can be terminated. This study provides specific tools to investigate the seizure-related heart rate response. Subjects may thus benefit from participation by identification of otherwise unknown arrhythmias. The rationale of the study (the high SUDEP risk and the evidence in animal studies for arrhythmic cause of sudden death) specifically applies to DS, a rare epileptic syndrome including minors and incapacitated persons. The investigators believe that the lack of risks, the potential diagnostic benefit, the minimal intervention with novel and wearable sensors and the possibility to terminate the study in case of discomfort, justifies the study in this patient group.
The purpose of this study is to determine if Apixaban is safer than a Vitamin K Antagonist given for 6 months in terms of bleeding in patients with an irregular heart beat (atrial fibrillation) and a recent heart attack or a recent procedure to open up a blood vessel in the heart. All patients would also be taking a class of medicines called P2Y12 inhibitors (such as clopidogrel/Plavix) and be treated for up to 6 months. The primary focus will be a comparison of the bleeding risk of Apixaban, with or without aspirin, versus a Vitamin K antagonist, such as warfarin, with or without aspirin.
Comparison of 2 doses of empagliflozin vs placebo in patients already using either an insulin regimen of multiple daily injections (MDI) or continuous subcutaneous insulin infusion (CSII). Randomisation to 3 treatments arms (equal assignment) following a screening period, an optimisation period and a run-in period. 52 week double-blind treatment period, and 3 week follow-up period.
This is a single arm explorative phase II clinical trial in 90 subjects with advanced stage melanoma harbouring a BRAFV600 mutation. PET imaging and molecular diagnostics are combined in order to monitor response to treatment with vemurafenib plus cobimetinib, examine development of resistance and correlate changes in metabolic/proliferative activity with extend of target inhibition.
Rationale: SABR (Stereotactic ablative radiotherapy) is one of the standard treatment options besides surgical resection for limited lung metastases (oligometastases) from colorectal cancer. High efficacy in terms of local control of metastatic lesions treated has been shown. Nevertheless, the precise effect of SABR upon progression-free- and overall survival in these patients is unknown. To further evaluate and develop local treatment options in metastatic disease, more information is necessary regarding the impact upon - and the pattern of - disease progression of local treatment options such as SABR. Objective: To determine the effect upon progression free survival and upon tumorload relative to baseline, both at one year after randomisation of immediate SABR versus delayed SABR (a scan-and-personalise policy). Secondarily, patterns of progression, patient-reported symptoms and quality of life will be monitored.
This study aims to explore the structural and functional characteristics of the pulmonary vasculature in adult Fontan patients. Objectives: - Determine the effect of pulmonary vasodilatation on indexed cardiac output during simulated exercise. - Characterization of structural properties of small pulmonary arteries.
Study to evaluate the efficacy and safety of capmatinib as a single-agent treatment for subjects with advanced/metastatic (stage IIIB or IV) non-small cell lung cancer (NSCLC) who had wild-type epidermal growth factor receptor (EGFR wt) (for exon 19 deletions and exon 21 L858R substitution mutations), anaplastic lymphoma kinase (ALK)-negative rearrangement, and mesenchymal epithelial transition (MET) mutations leading to exon 14 deletion (referred to as MET mutation hereafter) and/or MET amplification.
