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.
Prospective, multi-center, non-randomized, historical controlled, post-market study of patients requiring surgical repair of a focal articular cartilage lesion or osteochondral defect in the knee.
The purpose of this study is to find out whether rivaroxaban is safe to use in children and how long it stays in the body. Safety will be assessed by looking at the incidence and types of bleeding events. There will also be a check for worsening of blood clots.
The overall aim of this prospective, randomized study is to investigate whether acute coronary angiography (within 120 minutes) with a predefined strategy for revascularization, will improve 30-day survival in patients with out of hospital cardiac arrest with no signs of ST-elevation on ECG after Restoration of Spontaneous Circulation (ROSC). The patients will be randomized to a strategy of immediate coronary angiography within 120 minutes or to a strategy of delayed angiography that may be performed three days after the cardiac arrest.
Background: Despite considerable progress in the field of assisted reproductive technology (ART) maximum pregnancy rates generally do not exceed 30%. Furthermore, substantial differences in pregnancy rates are seen between women starting ART from seemingly similar clinical starting points and information on pregnancy/neonatal complications after ART is limited. For physicians and patients it would be extremely valuable if tools could be developed through which individualised chances of live birth and the development of pregnancy/neonatal complications can be calculated. In addition, there is increasing knowledge about health risks associated with subfertility and in particular with polycystic ovarian syndrome (PCOS) and premature ovarian failure (POF). An important void in research to date is the absence of a control group to check important new findings. Objectives: The study protocol aims to form a cohort of normo-ovulatory women with a regular indication for ART which can aid the investigators principle lines of research: 1. To study initial predictors of ovarian response to stimulation for IVF 2. To study predictors of chances for live birth after repeated IVF cycles 3. To assess the role for vascular health in the probabilities of success in ART treatment 4. To study predictors for pregnancy and neonatal complications 5. To form a control group for cycle disturbance studies Study design: In this part of the protocol, serum and material for DNA analysis will be collected by asking patients to have 20 ml of blood drawn during a routine blood withdrawal. This blood will be stored in the Biobank of the UMC Utrecht at -80 C. Study population: All women starting ART will be asked to participate. Women starting donorinsemination treatment will be asked to participate, from the viewpoint that they potentially will form a normal fertile control group. Nature and extent of the burden and benefits associated with participation: There are no benefits or risks for the study patient as blood is withdrawn during a routine venapuncture and results will not be used for clinical practice.
Through the COLA Study and Biobank the investigators hope to enable further identification of phenotype, endocrine, ethnic, and metabolic characteristics associated with menstrual cycle disturbances; and: the identification of genetic or other etiologic factors associated with cycle disturbances.
The purpose of this study is to investigate whether Bevacizumab (an anti-VEGF monoclonal antibody) added to a backbone chemotherapy regimen (Temozolomide, Irinotecan-Temozolomide or Topotecan-Temozolomide) demonstrates activity in children with relapsed or refractory neuroblastoma. Also, to investigate whether the addition of Irinotecan or Topotecan to Temozolomide increases the activity of chemotherapy.The primary objective of the study is the best response (Complete Response or Partial Response) while trial treatment, within 18 or 24 weeks depending on the arm of the trial the participant is randomised to. Secondary endpoints are assessing the side effects, the length of time before progression (Progression Free Survival) and overall survival (OS). This trial will address two important questions: - does targeting blood vessel development using bevacizumab, (a monoclonal antibody against the Vascular Endothelial Growth Factor (VEGF)), add to the effect on a tumour when used with existing chemotherapy, compared to the effect of the existing chemotherapy alone (temozolomide)? NOTE- This question has been completed. - does the addition of a second chemotherapy drug (irinotecan or topotecan) increase the effect on a tumour compared to the effect of one alone (temozolomide) NOTE - This question has been completed. - does the addition of dinutuximab beta added to a backbone chemotherapy (temozolomide or temozolomide + topotecan) increase the effect of backbone alone. Patients aged 1-21 years of age with relapsed or refractory high-risk neuroblastoma are randomised to one of two treatment arms: temozolomide-topotecan (TTo) or dinutuximab beta-temozolomide-topotecan (dBTTo). Temozolomide (T), irinotecan-temozolomide (IT), bevacizumab-T (BT), BIT (bevacizumab-IT), bevacizumab-temozolomide-topotecan (BTTo) and dinutuximab beta-temozolomide (dBT) are now closed to recruitment.
A pneumatic tourniquet is often used during total knee arthroplasty. However, its effect on postoperative outcomes as soft tissue damage resulting in delayed recovery remains unclear. The purpose of the present study was to compare tourniquet use versus non-tourniquet use during total knee arthroplasty for short-term functional recovery.
This study will evaluate the effects of switching Atripla to Eviplera on neurocognition measured by neuropsychological testing and functional MRI
Iatrogenic hypoglycemia is the most frequent acute complication of insulin therapy in people with type 1 diabetes (T1DM). Recurrent hypoglycemic events initiate a process of habituation, characterized by suppression of hypoglycemic symptoms, eventually leading to hypoglycemia unawareness, which creates a particularly high risk of severe hypoglycemia. Recent evidence suggest a pivotal role for (brain) lactate in the pathogenesis of hypoglycemia unawareness. Indeed, exogenous lactate administration may preserve brain function and attenuate counterregulatory responses to and symptomatic awareness of hypoglycemia. It is unknown whether endogenous elevation of plasma lactate produces the same effects and whether such effects differ between patients with T1DM with and without hypoglycemia unawareness and healthy controls. Objective: To investigate the effect of elevated levels of endogenous lactate on brain lactate accumulation and on counterregulatory responses to, symptomatic awareness of and cognitive function during hypoglycemia in patients with T1DM with and without hypoglycemia unawareness and normal controls. Hypothesis: The investigators hypothesize first that endogenous lactate, when raised through high intensity exercise, preserves neuronal metabolism during subsequent hypoglycemia, which in turn will attenuate counterregulatory hormone responses, appearance of symptoms and deterioration of cognitive function. Second, the investigators posit that these effects will be augmented in patients with hypoglycemia unawareness compared to healthy subjects and T1DM patients with normal awareness as a consequence of greater transport capacity of lactate into the brain.
Primary Biliary Cholangitis (PBC) is a serious, life-threatening, bile acid related liver disease of unknown cause. Without treatment, it frequently progresses to liver fibrosis and eventual cirrhosis requiring liver transplantation or resulting in death. The investigational drug, Obeticholic Acid (OCA) is a modified bile acid and FXR agonist that is derived from the primary human bile acid chenodeoxycholic acid. The key mechanisms of action of OCA, including its choleretic, anti-inflammatory, and anti-fibrotic properties, underlie its hepatoprotective effects and result in attenuation of injury and improved liver function in a cholestatic liver disease such as PBC. The study will assess the effect of OCA compared to placebo, combined with stable standard care, on clinical outcomes in PBC participants.
