There are about 13446 clinical studies being (or have been) conducted in Belgium. 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 is a prospective observational cohort multinational clinical study. There are no biomarkers to help predict in which patients acute low back pain (LBP) will transform into chronic low back pain (CLBP). Human variability and different common comorbidities complicate the picture and make stratification of patients into correct subgroups difficult. However, drugs act by targeting specific molecular pathways and are therefore efficient only in a subgroup of patients sharing common molecular pathology and common genetics. Both CLBP and disc degeneration are known to be heritable. Little investigation has taken place for genetic variants in CLBP. The main aim of this trial is to identify "omics biomarkers" associated with the transition from acute (single episode of low back pain) to persistent/chronic LBP (pain lasting more than 12 weeks).

We will verify if IV injected ICG may colour breast tumors and axillary lymph nodes after neoadjuvant therapy (chemo- or hormonotherapy)
The revision of our data shows that since its introduction in our institution (Jules Bordet Institute) in 1998 (until 2010, the year of the last review of cases), 53 patients underwent neoadjuvant therapy before selective sentinel lymph node dissection followed by conventional axillary dissection. The analysis of these cases shows that: - The lack of demonstration of sentinel lymph nodes observed in 8 cases (6 cN0) is associated in 75% of them with a pN+ status - If scintigraphic imaging is "positive" (demonstration of the sentinel lymph nodes: 35 cN0 and 10 cN+), our results appear favorable with a single false negative SLN result (False Negative Rate = 1/20 or 5%). Therefore we propose additional technique for LN detection by indocyanine green, we hypothesize that the combination of two different injections improves the technique of sentinel lymph node biopsy.
The purpose of this study is to investigate whether revalidation following total hip replacement through the percutaneous approach is faster or better than following the anterolateral approach. We assume this would be the case since it is possible to spare a large part of the gluteus medius muscle with the percutaneous approach.
The purpose of this study is to determine if NIR fluorescent imaging is an effective approach to detect the margins of head and neck tumours or lymph nodes draining the tumour
Patient with achalasia have a 10-50 fold increased risk to develop esophageal squamous cell carcinoma (ESCC). Early diagnosis of ESCC is essential, and detection of an earlier dysplastic stage is preferred. Endoscopic detection is however difficult and often delayed. Chromoendoscopy with Lugol dye increases detection rates dysplasia and ESCC to 91-100%. The aim of this study was therefore to evaluate a screening program using chromoendoscopy with Lugol to detect dysplasia in patients with idiopathic achalasia. A second objective is to study the relationship between foodstasis and the development op dysplasia
Prospective randomised controlled trial: 3 IUI cycles versus 1 IVF/ICSI cycle in women aged 38-42 years.
Background: The Apparent Diffusion Coefficient (ADC) acquired by Diffusion Weighted Imaging (DWI-MR) has been shown to correlate with cellular density. The ADC is indicative of Gross Tumour Volume (GTV), and preliminary data shows that the dynamics of DWI volumes during treatment (shrinkage) as well as dose to DWI volumes has impact on treatment outcome. Hypoxic tumour cells within the primary tumour have been identified to have prognostic importance for local control Tumour hypoxia is caused by insufficiency of the tumour vasculature leading to both chronic diffusion limited and acute flow limited hypoxia. Radioresistant hypoxic cells diminish the rate of local control, and the hypoxia driven increase in metastatic potential of the tumour and lowers the rate of distant disease control. Functional imaging has the potential to visualise radioresistant tumour subvolumes. PET scanning (18F-FAZA) is hypothesized to visualise hypoxic tumour subvolumes, and dynamic contrast enhanced (DCE) MR imaging has been used to quantify the extent of poor perfusion regions within cervical tumours. Objectives: Primary: Sensitivity and specificity of functional imaging (18F-FAZA PET (optional), T1w, T2w, DWI-MRI and DCE-MRI) to identify tumours with good and bad response to radio-chemotherapy Secondary: Determining whether there are differences in bias between centre. The difference in bias will be assessed for the T1 and T2 scans and the Ktrans and ADC maps.
The purpose of this study is to determine whether urinary connective tissue growth factor (uCTGF) can predict the onset of fibrosis in transplanted kidneys.
