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 goal of this observational study is to study a new method to compute ventricular-arterial coupling (VAC) in adult intensive care patients after cardiac surgery. VAC is a metric that describes the interaction between the heart and the arterial system. The new method of measuring VAC uses carotid ultrasound measurements. The main questions this study aims to answer are: - Can VAC measured using carotid ultrasound predict the hemodynamic response to drugs? - What is the concordance of VAC measurements obtained via carotid ultrasound with VAC measurements obtained via the standard, single-beat method? Measurements will be performed in the operating room and at the ICU.
This study will investigate the effectiveness of analgesia of ultrasound hematoma block compared to 'blind' hematoma block in patients with dislocated distal radius fracture.
The goal of this clinical trial is to prove that the RECAP test is capable of selecting advanced breast cancer patients sensitive for treatment with the PARP inhibitor talazoparib. Participants will undergo an ultrasound-guided biopsy and a blood withdrawal. Homologous Recombination (HR) deficient patients (approximately 30%) can start talazoparib treatment until progression of the disease or unacceptable side-effects and their response will be evaluated.
The goal of this clinical trial is to investigate the feasibility if a remotely administered smartphone app can increase the volume and intensity of physical activity in daily life in patients with isolated Rapid Eye Movement (REM) sleep behaviour disorder over a long period of time (24 months). Participants will be tasked to achieve an incremental increase of daily steps (volume) and amount of minutes exercised at a certain heart rate (intensity) with respect to their own baseline level. Motivation with regards to physical activity will entirely be communicated through the study specific Slow Speed smartphone app. Primary outcomes will be compliance expressed as longitudinal change in digital measures of physical activity (step count) measured using a Fitbit smartwatch. Exploratory outcomes entail retention rate, completeness of remote digital biomarker assessments, digital prodromal motor and non-motor features of PD, blood biomarkers and brain imaging markers. Using these biomarkers, we aim to develop a composite score (prodromal load score) to estimate the total prodromal load. An international exercise study with fellow researchers in the United States and United Kingdom are currently in preparation (Slow-SPEED). Our intention is to analyse overlapping outcomes combined where possible through a meta-analysis plan, to obtain insight on (determinants of) heterogeneity in compliance and possible efficacy across subgroups
The purpose of this single-center trial is to examine the effects of a slow-breathing technique performed at induction of anesthesia in patients undergoing surgery for breast cancer on anxiety, scored by Spielberger's State-Trait Anxiety Inventory, state scale (STAI-S),13 compared to usual care.
The objective of this prospective international cohort is to evaluate the LUMENEYE rectoscope for assessment on tumor response after total neoadjuvant treatment in rectal cancer. Patients included in this study will be patients who initially will be good candidates for organ preservation. The participating centers are all expert centers in tumor assessment. All patient assessments after neoadjuvant treatment for rectal adenocarcinoma will be included in each centre.
This is a multicenter, single arm, open-label, Phase 2 study in mutiple myeloma with newly diagnosed and treatment-naïve participants for whom high-dose therapy and autologous stem cell transplantation is part of the intended treatment plan. The study is evaluating a technique called Mass Spectrometry Minimal Residual Disease (MS-MRD) using blood samples and compares it with the minimal residual disease (MRD) technique using bone marrow samples.
In 2007, the frequency of so-called 'self-directed dying' in the Netherlands was investigated, that is, the voluntary cessation of eating and drinking or the taking of lethal self-collected medication. This research has not been repeated yet. Since 2007 there have been major developments regarding assisted and non-assisted dying, including the issue of a guideline by the KNMG and the endorsement by various political parties of a proposal for a new law on assistance in dying. There has also been much societal debate on euthanasia and assisted suicide as regulated by the Termination of Life on Request and Assisted Suicide (Review Procedures) Act. These developments may have had an influence on the frequency of self-directed dying. The primary objective of this cross-sectional questionnaire study with add-on qualitative interviews is to estimate how many people die each year in the Netherlands by either voluntarily stopping eating or drinking (VSED) or intentional intake of lethal medication attended by a confidant (ILMC). Secondary objectives include studying whether this number has changed since 2007; exploring possible explanations for changes in frequencies; and providing insight in the quality of dying of people who choose self-directed dying. To this end an online questionnaire will be sent out to a randomly drawn sample (n ≈ 37 500) from a large representative panel (NIPObase) of the Dutch adult population. A two-stage screening procedure will be used to check whether the experiences of the respondents represent a death VSED or by ILMC. The data will be analysed using quantitative software SPSS. From the respondents who indicate that they are willing to be interviewed, a sample will be taken from each group, 20 from VSED and 20 from ILMC. Interviews will be conducted by an experienced interviewer. The interviews are focused on better understanding people's choice for a self-directed death and on the perceived quality of the dying process for both methods. The interviews will be audio recorded and thematically analysed using qualitative software (N-Vivo).
Multicenter, prospective, non randomized, single arm evaluation of patients with overactive bladder (OAB) and/or fecal incontinence (FI) employing the Axonics recharge free SNM System.
Rationale: Patient-ventilator asynchrony (PVA) in mechanical ventilation is associated with adverse patient outcome such as a prolonged stay in the ICU and even mortality. The prevalence of asynchronies is, however, difficult to quantify. It is common to use only the pressure and flow signal of the ventilator to detect asynchronies. The detection method is often based on definitions. The investigators will use new techniques (esophageal pressure signal and machine learning (ML)) to improve detection and quantification of patient-ventilator asynchronies. The hypothesis is that an algorithm which uses the Pes signal and ML to detect and quantify asynchronies is superior to previous techniques. Objective: 1. To develop an asynchrony detection algorithm based on pressure, flow and Pes signal using ML. 2. To develop a second algorithm with the same ML technique based on pressure an flow signal only. 3. To compare the performance of these models in comparison with an expert team and with each other. Study design: The investigators will collect internal data from the ventilator connected to patients on mechanical ventilation (population described below). First, the investigators will, with a dedicated expert team, identify and annotate the asynchronies based on visual inspection of the pressure, flow and Pes signal. Second, the investigators will develop an ML algorithm which will be trained with the annotated data from the visual inspection. Third, the performance of the AI algorithm will be compared with the performance of the expert panel using newly obtained data. Fourth, the performance of the AI algorithm will be compared with the second algorithm which uses the pressure and flow signal only. Study population: All patients admitted to the adult ICU of the LUMC on mechanical ventilation who are ventilated > 24 hours and are equipped with an esophageal balloon catheter. Intervention (if applicable): None. Main study parameters/endpoints: The performance of the detection algorithm.
