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 aim of this study is to determine the incidence of recurrent caries around the different types of restorative materials (composites, amalgam, ceramics, crowns, etc.) and to better characterize recurrent caries lesions in terms of location and size of the lesions and type, material and age of the restoration.
This international, multicenter, prospective single arm Phase II biomarker discovery clinical trial with the primary objective of assessing the association of PFS with gene mutations, gene copy number aberrations and gene signatures in post-menopausal women with hormone receptor positive, HER2-negative metastatic or locally relapsed breast cancer whose disease has progressed after prior adjuvant endocrine therapy or one line systemic treatment, i.e., endocrine treatment or chemotherapy, administered for metastatic disease.
The purpose of this study is to determine whether etrasimod (APD334) is a safe and effective treatment for ulcerative colitis after 52 weeks of treatment.
Massage therapy during 1 month and evaluation of depression, hyperventilation, anxiety and quality of life
Aim With this retrospective study, the investigators would like to evaluate and, if possible confirm, whether earlier revalvulation of the right ventricular outflow tract is better than late revalvulation. Up to now, no analysis is done to validate this policy change. Patient selection All patients registered in the database of paediatric and congenital cardiology of the University Hospitals in Leuven, with sufficient follow-up data, and who underwent transannular patching at repair will be included in the study. Methodology and statistical analysis All files will be reviewed for demographic, electrocardiographic, echocardiographic, and outcome data. Besides descriptive statistics, Cox regression will be performed to detect whether the time period between repair and revalvulation influences clinical outcome (defined as death, heart failure hospitalization, redo-revalvulation, implantation of automatic defibrillator, endocarditis).
This is a 2 part study. In part 1 of the study, 3 different formulations of the same dose of tafamidis will be compared. Subjects will be fasted for each test and every subject will test all 3 different formulations. After swallowing tafamidis, tafamidis blood concentrations will be measured periodically for 6 days. After 14 days, subjects will take a different formulation of tafamidis and tafamidis blood concentrations will be measured periodically for 6 days. After another 14 days, the last formulation will be tested in the same way. In part 2 of the study, depending on the results of part 1, either none, one or 2 of the formulations tested in part 1 will be tested comparing the same formulation when given either with or without food. Additionally, depending on the results of part 1 of the study, different doses of the formulations may be compared.
Objectives: Study to evaluate safety and feasibility of an endoluminal vertical gastroplasty (EVG) using an endoluminal-suturing device. Briefly, Vertical gastric plication is a novel surgical approach for reducing the stomach capacity. Anterior surface plication and greater curvature plication are variations of vertical gastric plication that reduce the gastric capacity through infolding of the anterior surface or greater curvature of the stomach, respectively. These approaches have been tested, with positive results. A transoral or endoluminal approach (ie, a procedure that requires no incision, because access is granted through the mouth) offers the potential for additional benefit to the patient, because the procedures continue to become more and more minimally invasive. Advances in endoluminal devices are now allowing clinicians the ability to begin exploring bariatric procedures performed via flexible endoscopy. Although these procedures may not be as effective as their surgical counterparts, these less-invasive options may relieve patients of the significant risks associated with surgery. Study duration and number of subjects A period of approximately 6 months is anticipated form the time the time the first patient is enrolled to the completion of the last patient. The participants will be followed as follow: Day (0): Procedure Day (+1): Clinical Follow up and discharge (i.e. if no adverse effects observed) 1 month: Follow up endoscopy, Clinical assessment 3 month: Follow up endoscopy, Clinical assessment 6 month: Final assessment (Endoscopically and Clinical) On Parallel a nutritional specialist will monitor the patient on quarterly basis (1,3,6,12). Study procedures The intervention will be performed under general anesthesia with tracheal intubation. Endomina will be introduced into the stomach over guide wires and then fixed to the endoscope. The procedure will include the placement of 4-6 transmural anterior-posterior sutures after argon plasma coagulation of the tissue opposition areas in order to ensure persistence of the pouch reduction. Patient will be kept overnight after the procedure.
The primary objective of this study is to evaluate the effect of presatovir on nasal respiratory syncytial virus (RSV) viral load in RSV-positive lung transplant (LT) recipients with acute respiratory symptoms.
The purpose of these studies is to determine whether vestibular disorders could affect visuo-spatial cognition. Visuo-spatial cognition will be evaluated using a new questionnaire and a new computerized test using a digital tablet in different studies.
Cystinosis is a rare autosomal recessive disorder, characterized by the abnormal accumulation of cystine in the lysosomes. Cystinosis is mostly caused by mutations in the cystinosin gene (CTNS). The major mutation, which is present in almost 50% of the cystinosis patients, is a 57-kb deletion. This deletion removes the first 9 exons and a part of exon 10 of the CTNS gene. Exon 10 of the CTNS gene is a upstream 5' region that encodes for the CARKL gene and also for the first two noncoding exons of the transient receptor potential channel, vanilloid subfamily member 1 (TRPV1) gene. TRPV1 belongs to the transient receptor potential (TRP) superfamily of cation channels. TRPV1 is primarily expressed in sensory nerves and is activated by heating (>43°C) and a wide range of chemical stimuli. One of these chemical stimuli is capsaicin, the pungent ingredient in hot chilli peppers. The effect of binding of the exogenous ligand capsaicin with the TRPV1 receptor is well known to provoke the release of a number of bioactive substances including calcitonin gene-related peptide (CGRP). These substances, in turn, act on target cells in the surrounding tissue such as mast cells, immune cells and vascular smooth muscle cells. The resulting response is characterized by redness and warmth (secondary to vasodilatation), swelling (secondary to plasma extravasation) and allodynia (i.e. hypersensitivity to heat and touch secondary to alterations in the excitability of primary sensory neurons). The present study wants to test the following hypotheses: (i) The DBF response to topical applied capsaicin is decreased in cystinosis patients, compared to matched control subjects. (ii) The skin sensitivity response after topical applied capsaicin is decreased in cystinosis patients, compared to matched control subjects. (iii) The temperature sensitivity is decreased in cystinosis patients, compared to matched control subjects.
