There are about 13174 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.
Background. Guidelines on COVID-19 management are developed as we learn from this pandemic. However, most research has been done on hospitalised patients and the impact of the disease on non-hospitalised and their role in transmission are not yet well understood. The COVID HOME study conducts research among COVID-19 patients and their family members who were not hospitalised during acute disease, to guide patient care and inform public health guidelines for infection prevention and control in the community and household. Methods. An ongoing prospective longitudinal observational study of COVID-19 outpatients was established in March 2020 at the beginning of the COVID-19 pandemic in the Netherlands. Laboratory confirmed SARS-CoV-2 infected individuals of all ages that did not merit hospitalisation, and their household (HH) members, were enrolled after written informed consent. Enrolled participants were visited at home within 48 hours after initial diagnosis, and then weekly on days 7, 14 and 21 to obtain clinical data, a blood sample for biochemical parameters/cytokines and serological determination; and a nasopharyngeal/throat swab plus urine, stool and sperm or vaginal secretion (if consenting) to test for SARS-CoV-2 by RT-PCR (viral shedding) and for viral culturing. Weekly nasopharyngeal/throat swabs and stool samples, plus a blood sample on days 0 and 21 were also taken from HH members to determine whether and when they became infected. All participants were invited to continue follow-up at 3-, 6-, 12- and 18-months post-infection to assess long-term sequelae and immunological status.
The aim of this study is to assess the effect of total hip arthroplasty on hip disability and pain compared to non-surgery in patients with hip osteoarthritis, using target trial emulation to emulate a randomized controlled trial.
Patients with the transposition of great arteries (TGA) who undergo atrial switch operation and congenitally corrected TGA (ccTGA) patients have the right ventricle as their systemic ventricle. Function of the systemic right ventricle (SRV) could deteriorate which is associated with impaired prognosis. It is of paramount importance to understand the course and fate of these patients during a long-term follow-up to identify the determinants of adverse outcomes.
Prospective observational study, in which the primary aim of the study is to determine the incidence of perioperative hypovolemia in the elderly patient scheduled for major surgery. Hypovolemia is defined as the presence of fluid responsiveness, which equals increase in stroke volume > 10% after a passive leg raise according to the Nexfin non-invasive cardiac output measurement. This study aims to include 150 elderly patients aging 70 years or older undergoing scheduled major surgery. The passive leg raising test on 4 consecutive time points in the perioperative period.
The study hypothesizes that human who are both breastfeeding and pumping in the first days postpartum have more expression volume with an additional 5 minutes of pumping with Maintain program after pumping with the INITIATE program.
Researchers are looking for a better way to treat men who have advanced non-small cell lung cancer (NSCLC). NSCLC is a group of lung cancers that have spread to nearby tissues or to other parts of the body. Epidermal growth factor receptor (EGFR) and human epidermal growth factor receptor 2 (HER2) are proteins that help cells to grow and divide. A damage (also called mutation) to the building plans (genes) for these proteins in cancer cells leads to a production of abnormal EGFR and/or HER2. These abnormal proteins drive the growth and the spread of the cancer. Several EGFR and/or HER2 mutations exist in the cancer cells. The study treatment works by blocking the mutated EGFR and HER2 protein present in NSCLC cells and may help stop the further spread of NSCLC. BAY2927088 is under development, once it is approved, it may help treat people with NSCLC. The participants of this study will be healthy men and will have no benefit from the administration of BAY2927088. However, the study will provide important information for the design of subsequent studies with BAY2927088 in people with NSCLC. The participants in this study will get the non-radiolabeled and radio-labeled study treatment BAY2927088 in the form of tablets and solution by mouth and as an intravenous infusion in the arm. By radiolabeling the study treatment, researchers can track its movement and breakdown in the body of the participants. During the study, the study team will do physical examinations, take medical history, ask the participants questions about their smoking or alcohol consumption habits and other medications used, check vital signs such as blood pressure, heart rate, body temperature and the number of breaths taken per minute (respiratory rate), take blood and urine samples, do HIV (human immunodeficiency virus), hepatitis and optional COVID-19 tests per local regulations, and examine heart health using electrocardiogram (ECG). Each study participant will go through a first test phase (screening) of up to 28 days before the start of treatment. The study will have two parts. In part 1, the study participants will take a single dose of the non-radiolabeled study treatment in the form of tablets by mouth 30 minutes following a light meal. They will then receive the radiolabeled study treatment as an intravenous infusion in the arm over 15 minutes. After 2 days of washout, the same group of participants will move on to Part 2 of the study. They will take a single dose of the radio-labeled study treatment as a solution by mouth 30 minutes after a light meal. The participants and the study team know what treatment the participants will take. The total duration of the study will be approximately 8 weeks per participant, including an in house stay of approximately 23 days and 22 nights. There will be a final examination on the last day of their in-house stay before the participants are discharged and go home. The study doctors and their team will contact the participant to learn about the participant's health until the participant completes the study.
The aim of the present study is to determine the prevalence of anxiety in adult patients attending the ED of the Medical Centre Leeuwarden.
The goal of this clinical trial is to integrate genomic (WES/WGS) and other -omics technologies in order to find the genetic causes, in 500 patients (children and adults) with an unexplained metabolic phenotype in whom standard care (genetic and metabolic evaluation) did not provide a diagnosis. The overall aim of this study is to diagnose patients with an unknown metabolic phenotype. In addition, we want to provide evidence that the combination of approaches and techniques used in this study will increase diagnostic yield compared to current separated approaches. All participants will undergo a multi-omics(WES, WGS and metabolomics) approach to solve the unsolved genetic basis of their metabolic phenotype.
The MATER study is an observational cohort study on first ever transfusion recipients in six hospitals in the Netherlands, with information collected on both donor and patient characteristics. We aim to further specify which combination of characteristics of both donors and patients determine the increased risk of mortality after blood transfusions.
A cross-sectional dietary intake study was conducted with 423 Ivorian school aged children (SAC, 6-12 years) and 423 women of reproductive age (WRA, 15-49 years) from four cities, recruited by two-stage random sampling.
