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.
While most of the children spontaneously recover menstruation or experienced normal puberty after chemotherapy, their ovarian reserve may be impaired by treatment inducing future infertility. Fertility preservation is currently proposed for selected prepubertal patients with a high risk of premature ovarian failure after treatment (mostly conditioning regimen for bone marrow transplantation). For patients with low or moderate risks, counselling is very difficult and no fertility preservation procedure is usually proposed for these patients as no marker of the ovarian reserve has been validated in this young population to assess the individual risk. The primary objective of the study is to prevent long-term treatment-related infertility by detecting the young patients who normally progressed to menarche but have a reduced ovarian reserve. These patients may benefit from particular follow-up and fertility preservation procedure.
The purpose of this study is to assess the effect of IV clonidine administration on lower limb spinal motoneuron excitability during standardized total intravenous anesthesia (propofol and remifentanil).
Introduction: An emerging body of evidence indicates that there is an association between air pollution exposure in pregnancy and adverse pregnancy outcomes (Rudra, Williams, Sheppard , Koenig, & Schiff, 2011; Dadvand, et al., 2013; Ritz, et al., 2014). Adverse pregnancy outcomes tend to lead to adverse neonatal outcome and a higher economic cost. Epidemiologic studies have also revealed that cardiovascular complications during pregnancy, such als preeclampsia, are associated with a greater cardiovascular risk during later life ( Abramson & Melvin, 2014). Aim: This study wants to examine the effects of exposure to environmental factors, polluents and particulate matter on the clinical pregnancy outcome for mother and child and to determine which biochemical changes in maternal, placental and cord blood best explain this effect. Methods: This study will be performed in a prospective cohort setup (n=200), recruited from the prenatal clinic in the University Hospital Antwerp. The data collection consists of four questionnaires (intake, both urine samples and postpartum), two blood samples (28 weeks and post-partum), two urine samples (20 and 30 weeks), two hair samples (20 weeks and post-partum), cord blood and the placenta. Results and conclusion: As the study will start in November 2014, no results are available yet.
In this investigation the investigators would like to find out which of two commonly used techniques of management of palatally impacted canines: closed-window (CWT) or open-window (OWT), produces more favorable outcome.
The purpose of this study is to determine whether inspiratory muscle training is effective to improve breathless and exercise intolerance in symptomatic patients with chronic obstructive pulmonary disease (COPD) plus chronic heart failure (HF).
The investigators want to have a collection of fresh primary or recurrent tumor tissue for establishment of patients-derived xenografts in order to: generate a biobank of in vivo patient xenografts representing the different subgroups of tumors for head and neck cancer - perform genetic and transcriptional profiling of the primary, metastatic tumors and xenograft tumors - evaluate the efficacy of new targeted agents, whether or not in combination with standard treatment options - evaluate biomarkers of drug sensitivity - study primary and secondary (acquired) resistance in these models
Obese volunteers who have scheduled a gastric bypass (RYGB) in UZ Leuven will be asked to participate in a cross-over study using commercial available iron supplements. The aim of this study is to evaluate the absorption rate of different oral iron supplements in volunteers before and after RYGB (1, 3, 6 and 12 months post-RYGB).
OBJECTIVES: To evaluate the effect and cost-utility of a combination therapy of SPT+MAD compared with continuous positive airway pressure (CPAP) in patients with moderate positional obstructive sleep apnea (POSA). HYPOTHESIS: The SPT+MAD combination is more cost-effective and effective, in means of reduction of the apnea-hypopnea index (AHI), quality of life and compliance, compared with CPAP. STUDY DESIGN: A multicenter randomized clinical trial (RCT) will be performed with a follow-up of 12 months per patient. Patients will be randomized for CPAP or the combination SPT and MRA. All outcomes will be measured at baseline, month 3, 6 and 12. STUDY POPULATION: Patients diagnosed with moderate POSA according to polysomnography (PSG) results. INTERVENTION / STANDARD INTERVENTION TO BE COMPARED TO: The SPT trains POSA patients to sleep in non-supine positions, CPAP uses positive airway pressure to open the airway; MRA is an intra-oral prosthesis, which holds the mandible in a protrusive position, all to prevent effectively apneic events. OUTCOME MEASURES: AHI, compliance, quality-adjusted life year (QALY), direct and indirect costs, cardiovascular parameters, incremental cost-effectiveness ratio (ICER) SAMPLE SIZE / DATA ANALYSIS: 100 subjects in each treatment group, total of 200 patients. COST-EFFECTIVENESS ANALYSIS / BUDGET IMPACT ANALYSIS: The SPT is expected to improve the cost-effectiveness of overall treatment of POSA patients, and will save annually approximately 35-150 million euros.
After any acute brain injury, a primary pathophysiological response arises, enabling the brain to develop seizures and/or a status epilepticus (SE). These are frequently reported in patients admitted to the intensive care unit (ICU) with traumatic brain injury and brain injury caused by subarachnoid or intracerebral hemorrhage. Seizures can be presented without any clinical motor signs, which are then termed as nonconvulsive, and therefore remain frequently clinically unrecognized. As such, it is of great importance that these patients are diagnosed as early as possible since the increased metabolic demand and blood flow associated with an epileptic insult may further compromise the brain at risk. Thus far, continuous EEG (cEEG) is the only clinical instrument that is able to detect the development of early epileptic activity. Unfortunately, cEEG is not available in most ICUs and is labor-intensive, expensive and difficult to interpret for non-trained physicians. Therefore, a more simple and prognostic accurate EEG device is highly warranted to detect seizures in an early stage so that patients might benefit from a specific and early treatment. A validation study in comatose patients with an acute neurological insult will be conducted to provide evidence that simplified Bispectral Index EEG monitoring has the potential to detect epileptic activity as reliable as its gold standard, full EEG monitoring. Thereby, BIS EEG monitoring could possibly be used to facilitate the prognostication and management of epileptic seizures in this patient cohort which could eventually improve the clinical outcome.
Hypoxemia is commonly reported in patients admitted to the Intensive Care Unit (ICU) and may result from acute lung injury/acute respiratory distress syndrome (ALI/ARDS), sepsis, trauma and postoperative complications. In an attempt to preserve or increase the oxygenation, conventional mechanical ventilation is initiated in these patients. Unfortunately, patients frequently become refractory to standard ventilatory techniques and as such, gas exchange remains unaltered or becomes worse. High Frequency Percussive Ventilation (HFPV), on the other hand, is an advanced mode of ventilation which can be a salvage option in these patient cohorts as it has already been proven to improve gas exchange with success. The volumetric diffusive respirator (VDR-4; Percussionary, Corp., Sandpoint, ID) is the only commercially available system to deliver HFPV. This ventilator mechanically ventilates the lung by administering small successive subtidal volumes or percussions at unconventional high frequencies to reach an optimal diffusive oxygenation. Since it has been known that hypoxemia due to a reduced oxygenation results in secondary brain injury, it is conceivable that the cerebral tissue oxygenation might be impaired as well. It has been strongly suggested that a cerebral tissue oxygenation in the optimal range has an ameliorative influence on hypoxic events and in turn leads to a better clinical outcome. Thus far, no studies have been conducted to investigate if an improved oxygenation by means of a switch to HFPV automatically leads to an increment in the cerebral tissue oxygenation. With the use of Near-Infrared Spectroscopy (NIRS) technology, investigators will investigate whether this alternation of ventilation strategy is associated with a (beneficial) change of the cerebral tissue oxygenation.
