There are about 13384 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.
Pharmacokinetics of antibiotics in critically ill neonates, infants and children on extracorporeal membrane oxygenation (ECMO).
The CONSCIUS study is a prospective, interventional study including patients with acute brain injury and impaired consciousness implanted with intracranial electrodes. The aim of the study is to investigate seizures and thalamocortical neural dynamics underlying behavioral unresponsiveness.
The goal of this observational study is to analyze the characteristics of left atrial electroanatomical maps in patients without a history of atrial fibrillation but with a high clinical risk of developing it, as indicated by the presence of structural heart disease or a CHA2DS2-VASc score ≥ 2 points. The study cohort will be compared to a historical cohort of patients with diagnosed atrial fibrillation in a propensity-matched fashion. The main questions it aims to answer are: - Are the left atrial electroanatomical changes a consequence or a precursor to the development of atrial fibrillation? - Are the left atrial electroanatomical findings different between patients with atrial fibrillation and those at high risk of developing it? - What is the prognostic impact of left atrial pathologic changes in patients without diagnosed atrial fibrillation in terms of cardiovascular outcomes?
The goal of this study is to validate a new method for the assessment of orofacial muscles in FSHD affected individuals, using maximal expiratory pressures (MEPs). Our hypothesis is the following: - The pressure drop observed when using circular mouthpieces (versus ovoid mouthpieces) is a reflection of orofacial dysfunction in FSHD affected individuals
The goal of this interventional clinical trial is to investigate whether combining photoplethysmography (PPG) signals with accelerometer (ACC), gyroscope (GYR), sound, and electrocardiography (ECG) derived smartphone data provides additional insights into the cardiac condition of individuals with and without atrial fibrillation (AF).
The goal of this clinical trial is to optimize hearing aid benefit based on the individual auditory-cognitive need using different hearing aid features in first-time hearing aid users between 45-80 years old with bilateral Phonak Audéo Paradise/Lumity 70 hearing aids. The main questions it aims to answer are: Does cognitive functioning affect hearing aid benefit? How can hearing aid fitting be optimized based on the individual auditory-cognitive profile? The hypothesis posits that cognitive abilities influence the effectiveness of hearing aids, alongside hearing status. Furthermore, if features of hearing aids improve speech understanding and listening effort, it is proposed that individuals with lower cognitive functioning will experience heightened benefits from hearing aids. The study will consist of three groups: one control group and two groups where one different feature will be modified. Participants will be tested at baseline measurement, including: - screening tests - audiological tests - questionnaires - cognitive tests - real-ear-measurement Following this, participants will be divided in one of the three groups, after which speech audiometry will be repeated. After a 4-week acclimatization period, the second measurement will take place, repeating speech audiometry and questionnaires. Subsequently, the hearing aid settings will be restored to their initial configuration.
The aim of this project is to study the presence of cancer-associated adipocytes in oesogastric cancers and their possible links with myosteatosis. This research project has a retrospective component, the aim of which is to analyse the body component based on imaging in patients with oesogastric neoplasia in order to determine the incidence of myosteatosis and to study the relationship with oncological and prognostic data. The second part of the project is prospective and will collect biological material (skeletal muscle, adipose tissue, tumour, blood) for histological, molecular and genomic analyses and will analyse muscle function in patients with oesogastric cancer. It will address the role of adipocytes in the tumour microenvironment of oesogastric cancer, focusing on their interactions with the observed muscle myosteatosis and prognosis. In the future, it will help to identify signalling pathways, targets and patients who could benefit from appropriate treatment.
Neutrophils are first responders to any kind of threat the body faces: infection, severe trauma, cancer, surgery... They produce the cytokines, induct oxidative stress and de-granulate toxic proteins to kill pathogens. However the new mechanism related to the neutrophil extracellular traps release has been recognized as a new way of cell necrosis and has been called a NETosis. NETosis is a hugely important new mechanism of human immune responses also described in various forms of acute kidney injury (ischemic, toxic, autoimmune). In certain kidney diseases, neutrophils release NETs and induce cell necrosis. Whether neutrophils die along with NET release, and if they do die, remains under study and is most likely context dependent. Extracellular traps (ETs) can be released also by macrophages. The ETs formation as well as macrophages extracellular traps (MET's) especially in kidney disease are cytotoxic and elicit inflammation, contributing to necro-inflammation of the early-injury phase of acute tubular necrosis in anti-neutrophil cytoplasmic antibody-related renal vasculitis, anti-glomerular basement membrane disease, lupus nephritis. Finally, acute kidney injury-related releases of dying renal cells or ETs promote organ injuries - for example, acute respiratory distress syndrome. According to the recent review the term 'NET formation' has been proposed as a better term to use instead of 'NETosis'. The formation of neutrophil extracellular traps (NETs) has been recently recognized as a unique modality of pathogen fixation (sticky extracellular chromatin) and pathogen killing (cytotoxic histones and proteases) during host immune responses, as well as collateral tissue damage. Histones are potent mediators of injury in various cells. Indeed, extracellular histone induce microvascular endothelial cells and renal epithelial cells death in vitro, forms the pores that disrupt cell integrity and induce the cytolysis by their capacity of binding with membrane phospholipids and activation of inflammasome in the kidney leading to auto-entrainment of inflammation. The activation of inflammation has been demonstrated in the experimental model of crystalline nephropathy related to the uncontrolled oxalate urinary excretion. Inhibition of inflammasome activation has been related with the preservation of kidney function. In patients with kidney stone disease the presence of crystals in the urine has been demonstrated to induce tubular epithelial cells injury that can theoretically trigger the NET's or MET's release and tissue inflammation. NETs are now increasingly described as new targets for therapies, however largely under-estimated. The role of release of ETs from neutrophils and macrophages during the kidney stone disease has never been studied in urine but the neutrophil extracellular trap (NET) formation-NETosis - was found significantly increased in the papillae of patients with brushite stones compared with CaOx stones. The key objectives of this study are: 1. to assess NET/MET's excretion in the urine as a non-invasive method of NET/MET'osis measurement in patients with kidney diseases as a new biomarker of early stage of cells damages reflecting kidney injury occurring in patients with uncontrolled stones and other renal diseases; 2. to compare the NET/MET's concentrations in the urine with those in plasma
Studies have shown that non-contact boxing benefits individuals with Parkinson disease. Yet, the content of such sessions, has not yet been investigated. The following research question has therefore been asked: What is the physical intensity, in terms of both movement quality and quantity, as well as cardiovascular demand, in a group of individuals with Parkinson's disease during a one-hour session of Parkiboks? Though the study is exploratory, the investigators hypothesize to observe increases in cardiovascular activity during the session, as well as a high number of upper-limb repetitions of near maximal range of motion.
This study aims to determine and compare the precise skeletal dental and soft tissue effect of Mandibular advancement aligners and Herbst Appliance.
