There are about 13332 clinical studies being (or have been) conducted in Netherlands. 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.
Cannabis use by people with schizophrenia is associated with family distress and poor clinical outcomes. Therefore, an Family Motivational Intervention (FMI) was developed to help parents to motivate their child with a diagnoses of recent-onset schizophrenia to reduce cannabis use. In a single-blind randomised clinical trail with 75 patients with the diagnosis of schizophrenia, parents will be assigned to either FMI or to routine care. Assessments will be conducted at baseline and at a 10- and 22-month follow-up. The study hypothesis is that FMI will be more effective than routine care in reducing (a) cannabis use in patients and (b) distress and sense of burden in parents.
The purpose of this study is to determine whether cardiac resynchronization therapy with the use of an implanted electronic pacemaker reduces morbidity associated with chronic thromboembolic pulmonary hypertension
The main purpose of this cluster randomized controlled trial is to evaluate the difference in effectiveness between a combined implementation strategy and an educational strategy on the implementation of a community occupational therapy program for clients with dementia and their primary caregivers.
Rationale: Cardiovascular diseases are important causes of morbidity and mortality in the industrialized world. Clinical studies indicate an important role for the proteins of the contact activation system (coagulation factor XII (FXII), FXI, prekallikrein and high molecular weight kininogen (HMWK)) on the risk of cardiovascular disease. There is substantial evidence from mouse studies that FXII and FXI participate in the formation and stability of thrombi and in vitro studies showed that collagen is able to activate FXII and hereby stimulate thrombin formation and potentiate the formation of platelet-fibrin thrombi. The investigators want to determine the role of the proteins of the contact activation system in platelet mediated thrombus formation in human blood. Objective: The investigators will study the effects of the proteins of the contact activation system on platelet mediated thrombus formation, embolization and degradation on collagen in a perfusion flow model. Study design: Blood will be collected from human volunteers via a venipuncture in the forearm. Each volunteer will donate maximally four times 30 ml of blood over a period of two days. This blood is used in perfusion flow experiments: blood flows over a coverslip covered with collagen in a flow chamber. The investigators will vary several conditions such as the concentration of the proteins and the shear rate. For perfusion flow experiments, the investigators need fresh whole blood because platelets are viable for four hours. After this time, new blood is needed. Study population: For this study the investigators need blood from human volunteers with a coagulation defect in one of the proteins of the contact activation system, e.g. FXII, FXI, prekallikrein or HMWK and controls without any coagulation defects. Main study parameters/endpoints: The investigators main study endpoint is the ex vivo formation of platelet-mediated thrombi on collagen in a perfusion flow model. The investigators hypothesize that thrombi formed from blood of patients deficient in FXII or FXI are less stable than those formed from blood from controls.
The incidence of severe morbidity and mortality following an influenza infection during the annual influenza epidemics is highest among the elderly population and 90% of influenzaassociated mortality occurs in this group. Vaccination is considered the best preventive intervention available but offers only partial protection. The protective effect decreases with advancing age and existing co-morbidity. Therefore, in spite of high compliance with vaccination, the risk of influenza-related complications among nursing-home residents, is particularly high, and consequently also the associated disease and economic burden. There is debate on the potential health benefit of the antiviral activity of oseltamivir as an effective supplementary intervention to prevent or contain influenza outbreaks in nursing homes. Although effectiveness of post-exposure prophylaxis (PEP) with oseltamivir on preventing transmission has been demonstrated in trials among healthy (mainly unvaccinated) adults and children, effectiveness has not yet been assessed among vulnerable vaccinated highrisk groups, such as the elderly population in nursing homes. If proven (cost)effective, oseltamivir could have considerable benefits in this setting, although constraints relating to implementation need to be addressed as well.
Rationale: The effect of vertical dimension on sleep apnoea and respiratory variables in obstructive sleep apnoea patients. Objective: To what extend should a possible worsening of the OSA condition, caused by an increase of mouth opening be taken into consideration in daily dental practice, when an occlusal stabilization splint (OSS) is placed in the mouth. Study design: Cross over RCT-design Study population: OSA patients referred to ACTA from the Slotervaart Hospital, for treatment with a Mandibular Advancement Device (MAD), at least 18 years old. Intervention: Occlusal stabilization splint (OSS) for the upper jaw and a controlled condition in a cross-over design Main study parameters/endpoints: Apnoea- Hypopnoea Index (AHI) and the Epworth Sleepiness Scale (ESS). The aim of this study is to determine the effect of vertical dimension of OS on sleep and respiratory variables in OSA patients. The hypothesis is that insertion of an OSS and an increase of the vertical dimension will result in a significant increase in the AHI.

Introduction: The primary function of the gastrointestinal (GI) wall is digestion and absorption of nutrients that are important for growth and development. The second important function of the GI wall is forming an effective barrier to prevent penetration of potentially harmful components from the inside of the gut (lumen), via the GI wall, into the body. A compromised barrier function may play an important role in the development of a range of inflammatory GI diseases such as coeliac disease, Inflammatory Bowel Disease (IBD), food allergy, but also in the pathophysiology of postoperative complications. It is important and clinically relevant to have reliable GI permeability tests, however the existing test leave room for improvement. Rationale/aim: Three new tests are developed to assess gastrointestinal permeability in both normal controls with and without raised permeability, and in patients with coeliac disease. In the current study these new permeability tests will be evaluated and compared with the golden standard permeability test, the dual sugar test.
