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.
The present cross-sectional study aims to examine the cognitive capabilities of older adults, aged 50 to 89, with normal hearing or age-related hearing loss by means of the Repeatable Battery for the Assessment of Neuropsychological Status for Hearing impaired individuals (RBANS-H). Secondly, the correlations between cognition on the one hand and hearing and speech reception capabilities on the other hand are investigated. For this purpose, twenty participants are included in the age categories 50 to 59, 60 to 69, 70 to 79 and 80 to 89, bringing the total number to 80. Three questionnaires are administered to the participants: the Health Utilities Index-2/3 (HUI 2/3), Dizziness Handicap Inventory (DHI) and a general questionnaire on education and profession, medical history, hearing aid use and tinnitus. Also an audiological examination is performed, including pure tone audiometry, speech in quiet and speech in noise audiometry. Finally, cognition is assessed using the RBANS-H.
In approximately half of individuals with Down syndrome, an higher than normal number of vessels cross the optic disc margin. Investigator hypothesize that early retinal vessel branching occurs due to inhibition of angiogenesis by triplet overexpression of endostatin, an angiogenesis inhibitor encoded on chromosome 21. Since angiogenesis is critical in the development of eyes and other organs angiogenesis depended (specially kidney, brain, and recently described lungs and heart), early branching of retinal vessels at the level of the optic disc would also likely result in abnormal renal and other organs development in these individuals. Investigator wish to determine whether observation of optic disc vessels may serve as an indicator of elevated endostatin levels and other angiogenesis-dependent organs anomalies.
Database registering demographic patient data, anesthesia and surgery information, post operative recovery and complications if any.
Prospective observational study. A substantial number of patients do not respond favourably to sacral neurostimulation (SNS) although clinically, they appear to have the same lower urinary tract (LUT) dysfunction characteristics as the good responders. This may be due to methodological issues (lead position) or patient selection. The purpose of this study is to improve and standardize lead position, in order to increase the patient response to test stimulation and to SNS treatment, and to decrease adverse events.
The general objective of this project is to determine the best method to measure maximal inspiratory flow rates, to study their reproducibility and create reference equations in healthy subjects.
The goals of this research will be to define some of the mechanisms underlying the progression and complications of heart failure (HF) with preserved left ventricular ejection fraction (HFPEF) Aim 1: to evaluate the differences in cardiac structure, function and fibrosis markers through the spectrum of HF stages in order to deepen the understanding of the pathophysiology driving HF progression. Aim 2: to define the mechanisms by which HF risk factors, such as hypertension, diabetes, obesity, and renal insufficiency, interact with age to increase HF risk, and to evaluate the role of precipitating factors such as myocardial ischemia, atrial fibrillation in HFPEF. Aim 3: to determine prognostic factors in HFPEF patients, by following these patients over time. Accordingly the investigators will correlate baseline data (echocardiographic, MRI or biomarkers) with incident cardiovascular events and determine whether these measures provide incremental prognostic information beyond clinical characteristics.
The present study is designed as a observational prospective, multicentre, international. The main aim of this study is to evaluate the safety and feasibility of SVC isolation with the CB in a prospective manner.
In the VITdAL-ICU trial using a large oral dose of vitamin D3 in 480 adult critically ill patients, there was no benefit regarding the primary endpoint hospital length of stay. However, the predefined subgroup with severe vitamin D deficiency (25(OH)D ≤ 12ng/ml) had significantly lower 28-day mortality (36.3% placebo vs. 20.4% vitamin D group, hazard ratio (HR) 0.52 (0.30-0.89), number needed to treat = 6). Therefore, high-dose vitamin D3 in a population of severely vitamin D deficient critically ill patients is a promising and inexpensive intervention that requires confirmatory multicenter studies. To date, only 7 interventions (e.g. noninvasive ventilation or prone positioning) have ever demonstrated mortality benefit for Intensive Care Unit (ICU) patients in multicenter trials. In case of benefit, vitamin D treatment in critically ill patients could be immediately implemented worldwide.
Evaluation of central (cerebral) effects of Pulsed RadioFrequency (PRF) on the lumbar DRG (Dorsal Root Ganglion), using fMRI (functional Magnetic Resonance Imaging ). Feasibility study (after which an interim analysis is done): 5 subjects in order to detect measurable central effects inducted by PRF on DRG, follow up study 20. Total amount of subjects 25.
Type 2 diabetes is a chronic condition whose prevalence is increasing globally. Kidney disease is a key complication of diabetes and is among the most common cause of end-stage renal disease, requiring renal replacement therapy. It has been shown that the trajectory of renal function (estimated glomerular filtration rate - eGFR) is of great prognostic value for renal and cardiovascular endpoints in diabetic patients. However the clinical use of this prognostic marker is not associated to date with a clear therapeutic intervention, effective in patients with type 2 diabetes identified with this biomarker. In France, type 2 diabetes patients have twice less physical activity than non-diabetic persons. Recently, it has been published that physical activity was associated with an improvement of renal risk in patients with type 2 diabetes, recruited from the LOOK-AHEAD study. It was demonstrated that high-intensity physical activity (HIPA) can have several additional advantages over moderate-intensity, on blood pressure improvement, and cardiovascular risk profile modification. In addition, this procedure was shown to be safe in patients with high cardiovascular risk. We plan to perform a randomized intervention comparing a structured program of high-intensity physical activity (HIPA) vs standard recommendations for physical activity on renal function decline (primary outcome) and mortality, renal and cardiovascular endpoints, patients' safety and quality of life (secondary outcomes). Study participants will be patients with established type 2 diabetes and a high renal risk, identified by rapid renal function decline, defined as a eGFR slope below -5ml/min per 1.73 m2/yr. The intervention is planned to last for 2 years.
