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.
Intraoperative cell salvage is an important measure of patient blood management but its effectiveness in patients undergoing revision total hip arthroplasty remains unclear. Over the last decade, we have used intraoperative cell salvage systematically in this group of patients. However, since the use of cell salvage has a cost and requires additional resources, we decided to retrospectively investigate its usefulness in this particular indication.
multi-center, randomized, double-blind, placebo-controlled, dose-finding, 4-arm, parallel assignment study to evaluate the efficacy of three different doses of sulthiame (STM) compared to placebo on sleep apnea activity in adult patients with obstructive sleep apnea.
In some cases the standard J-tip guidewire cannot deliver the catheter into the aortic root, because of arterial loops or spasm. In these cases a hydrophilic guidewire (Terumo) gives the right lubricity and good shape retention to guide the catheter through the artery. However, the Terumo wire does not give much torque and could therefore easily penetrate side branches and cause dissection or perforation. The latest Silverway guidewire has some new advantages which is easier to guide and could cause less complications while faster delivery of catheters to the aortic valve. The investigators aim to compare both guide wires.
Prospective, single-arm, multicenter study of patients with an intermediate pre-test probability of CAD and positive exercise stress tests referred for invasive angiography. Patients underwent an invasive diagnostic procedure (IDP) with measurement of fractional flow reserve (FFR) and index of microvascular resistance (IMR) in at least one coronary vessel. The objective was to determine the false discovery rate (FDR) of cardiac exercise stress tests with both FFR and IMR as references.
The objective of this qualitative study is to create a better understanding of patients' mental model of health data engagement interfaces and tools (such as Dynamic Consent). The researchers will focus especially on those people who - plausibly - require adjusted communication particularities and interaction modalities due to a cognitive impairment stemming from a neurodegenerative disease. Taking into account the specific characteristics of patients with dementia, the goal of this study is to investigate how to communicate according to patients' personal skills and capabilities and identify both the proper support mechanisms for engagement 2.0 consent as well as feedback mechanisms (return of research results). Through a focus group & interview setup, this study will discern design requirements and propose design recommendations for the (future) development of health data engagement interfaces.
Even in a chronic phase after stroke, most patients have difficulty moving the affected arm, resulting in limitations in simple tasks in daily living, most frequently limiting reaching task. In the chronic phase, significant improvements are usually no longer observed. Nevertheless, even these patients can still improve their functional abilities due to exercise-dependent plasticity. A new device was developed, the deXtreme robot, a rehabilitation device that offers error-enhancement approach during three-dimensional movements. The goal error-enhancement is to elicit better accuracy, stability, fluidity and range of motion during reaching. games are projected on a screen, requiring 3D active reaching movements. The duration of the study for a single participant will be 7 consecutive working days, including 1 day of pre-intervention assessment, 5 days of training and 1 day of post-intervention assessment. The overall aim of this project is to gain knowledge into the potential of error-enhancement robot training in patients with upper limb impairments in the chronic phase after stroke. Hypothesizing that the 5-day training will have a positive effect on both the robotic and clinical outcome measures.
determine the safety and effectiveness of the device.
In a recent cross-sectional study, it was shown that people with a good observed upper limb (UL) motor function but low perceived UL activity show a reduced daily-life UL activity. The investigators will now investigate the feasibility of a phone-monitored home exercise and feedback program for the UL following stroke and the preliminary effects on the perceived UL activity and actual daily-life UL activity for participants with good observed UL motor function but low perceived UL activity in the chronic phase post-stroke.
TENT-A3 is a single arm repeated measures prospective investigation evaluating the safety and efficacy of the Lenire device for tinnitus treatment. The Lenire device provides non-invasive bimodal (sound and tongue) stimulation to alleviate the symptoms of chronic, subjective tinnitus. Participants presenting to one of the several study sites with a diagnosis of chronic subjective tinnitus who meet the inclusion criteria are enrolled in the investigation while the study site is active. The objective of TENT-A3 is to determine whether the addition of tongue stimulation to sound-only stimulation provides additional clinically significant improvements in tinnitus symptoms beyond that of the sound-only stimulation component of the bimodal treatment.
Olfactory dysfunction (OD) is a well know symptom of coronavirus disease 2019 (COVID-19), accounting for 48 to 85% of patients. In 1 to 10% of cases, patients develop a chronic olfactory dysfunction (COD,) lasting more than 6 months. Recently, platelet-rich plasma (PRP) was used in patients with non-COVID-19 COD and authors reported encouraging results. In the present study, the investigators investigated the usefulness and safety of PRP injection in 56 patients with COVID-19 COD. Our results showed that PRP in the olfactory cleft can increase the olfactory threshold one month after the injection. Moreover, our results suggest that timing of treatment may be an important factor and that PRP is a safe treatment because no adverse effects were reported throughout the study
