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 operating room environment can be a source of anxiety for the patient, including in the context of outpatient surgery for which anxiolytic medication is rarely used. This anxiety-induced effect can be reinforced by the patient's lack of active participation. Some studies have already shown the feasibility of patient walking to the operating room (OR) and advantages this approach(Kojima and Ina 2002; Lack 2016; Nagraj et al. 2006). Moreover, recovery room complications and pain have also been shown to be greater after varicose vein surgery in patients with significant preoperative anxiety (Scavee et al. 2016). Therefore, the investigators decided to test the effects of walking to OR for patients admitted for outpatient surgery for varicose vein surgery.
This is an open, prospective, and interventional study investigating the potassium measurement with the CardioRenal device in capillary blood. It will be conducted at one investigational site. Each subject will have capillary blood collections. Additionally as a reference a venous blood collection will be conducted
This is an international, cross-sectional and descriptive study that aims to investigate differences in patient-reported outcome measures (PROMs) and patient-reported experience measures (PREMs) and that aims to explore the profile and healthcare needs of adults with congenital heart diseases.
A multitude of exercise therapy modalities are effective in improving daily physical function and relieving pain in various forms of chronic musculoskeletal pain (CMP) such as chronic neck pain, osteoarthritis, fibromyalgia, and chronic low back pain. However, the inital pain response to physical exercise can be variable in populations with CMP. Indeed, some studies show no change or even brief exacerbations in pain in individuals with CMP in response to exercise. These pain flare-ups in chronic pain populations are believed to be associated with increased pain sensitivity after exercise. The magnitude of "exercise-induced hypoalgesia" or the EIH response (i.e., the short-term endogenous pain-suppressing response after exercise) is believed to depend on several training factors, including exercise intensity. Currently, there is limited understanding of the optimal intensity of exercise for producing hypoalgesic effects on different types of pain stimuli. Nevertheless, several indications have been found for a dose-response effect in exercise and the amount of EIH that can be expected. However, very few studies have specifically examined EIH in people with chronic low back pain, although exercise is recommended in national and international guidelines as a basic treatment for the treatment of this condition. Relevant studies have also shown that exercise can induce an extensive inflammatory response in CMP, which may contribute to the disrupted EIH production. In addition, it is stated that this inflammatory response in CMP is also influenced by psychosocial factors. Therefore, the aim of the current cross-sectional cohort study is to expand the knowledge of the pain processing and inflammatory response to acute physical exertion in persons with chronic low back pain through evaluation responses of persons with this disorder to a high intensity training protocol. It is also investigated whether their EIH response is dependent on psychosocial factors.
The investigators hypothesize that the level of PEEP is often suboptimally applied in certain operative conditions, such as in laparoscopy with head down (Trendelenburg) positioning. This can result in excessive levels of lung stress and postoperative pulmonary complications. In patients with steep Trendelenburg and a pneumoperitoneum, the investigators aim to 1. measure apical versus basal atelectasis using the lung ultrasound score 2. compare lung ultrasound scores at different PEEP levels 3. compare respiratory mechanics at the different PEEP levels 4. contrast the optimal PEEP level to standard practice 5. provide guidance to optimal PEEP titration in this setting for the clinician
With this double- blind, randomised, placebo-controlled study, the investigators want to investigate the influence of a chewable with the probiotic strain Lacticaseibacillus rhamnosus GG on the symptoms and immunological markers of allergic rhinoconjunctivitis (AR). In addition, the investigators aim to study the influence of this probiotic chewable on the microbiome of the upper respiratory tract after administration in adults with AR. The bacterial and cytokine profiles in the naso- and oropharynx will be monitored before, during and after the treatment.
Flow controlled ventilation (FCV) is a fairly new mode of mechanical ventilation, consisting of a constant inspiratory and expiratory flow. Inspiration is thus comparable to volume controlled ventilation (VCV). The actively controlled, constant flow during expiration is unique. FCV is known to minimize dissipated energy to the lung [ref] and is therefore supposed to aid in lung protective ventilation. The VICAR study is designed as a prospective single cohort crossover trial. The intervention consists of a sequence of respiratory modes: baseline pressure controlled ventilation (PCV) during 5 minutes, followed by 30 minutes of FCV with an evone respirator (Ventinova Medical B.V., Eindhoven, The Netherlands) and eventually 30 minutes of VCV. Every participant will receive the intervention. Respiratory rate (RR), positive end-expiratory pressure (PEEP) and inspiratory fraction of oxygen (FiO2) will be held constant. According to the manufacturers guidelines, an I:E ratio of 1:1 will be pursued during FCV. During FCV, the respirator will be set with the same PIP as during baseline PCV. For VCV, the same tidal volume as during baseline PCV will be set.
Maintaining adequate perfusion pressure and oxygen supply is essential for organ survival. Splanchnic hypoperfusion during the perioperative period in abdominal surgery may result in mucosal ischemia with increased permeability of the gut barrier. Additionally, the liver is also sensitive for hypoxemia and hypoperfusion, especially during liver surgery. Anesthetics (such as propofol or sevoflurane) have a cardiovascular depressant effect, resulting in a reduction of cardiac output (CO). Dobutamine is used to counteract myocardial depressant effect of anesthetics. Additionally, dobutamine is frequently used during abdominal surgery to maintain splanchnic perfusion. Dobutamine could increase hepatic blood flow (HBF) indirectly by increasing cardiac output or directly by stimulating adrenergic receptors in the splanchnic circulation. The hepatic circulation has a large number of alpha and beta adrenergic receptors and could be sensitive for adrenergic stimulation such as dobutamine. Hence, dobutamine could have a direct effect on the hepatic vasculature. The aim of the study is to evaluate the effect of dobutamine on hepatic blood flow during goal directed hemodynamic therapy and to distinguish between potential direct and indirect effects.
The safety and efficacy of once daily application of IDP 126 Gel will be compared to Epiduo® Forte and IDP-126 Vehicle Gel.
The objective of this study is to assess the interest and the efficiency of a warm-up prevention program on the prevalence of shoulder injuries in amateur volleyball players. Around ten teams will be included in the study. They will be divided into two groups (blind): an intervention group and a control group. A warm-up prevention program will implemented in the teams of intervention group. This program will have to be followed twice a week, at the beginning of the training session. In both groups, shoulder injuries will be registered each month by an online questionnaire.
