There are about 11304 clinical studies being (or have been) conducted in Denmark. 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 benefits and harms of antipsychotics are relatively well studied in adults. However, there is a lack of scientifically valid studies regarding the benefits and harms of antipsychotics in children and adolescents with psychosis. The main objective of the TEA trial is to compare the efficacy and adverse reactions of two antipsychotics (quetiapine versus aripiprazole) in children and adolescents between 12-17 years of age with psychotic symptoms on psychopathology, cognitive deficits, and daily functioning. Furthermore, the trial will focus on adverse reaction profiles of the two antipsychotics as well as early predictors of later sustained clinical effects of these antipsychotics.
Younger hip patients often need revision of their hip replacement due to wear and loosening. Newer concepts (resurfacing and large head total hip replacement) with articulation surfaces in metal may reduce the wear, increase the longevity of the implant and give an improved function. The possible downside is that these concepts releases metal debris to the body. The investigators wish to see if the newer interventions are a clinical improvement compared to standard. The investigators also wish to investigate the extent of metal released to the body and any effect on the immune system. Finally the investigators wish to investigate the stability of these new implants and their ability to preserve the bone around the implant. The investigators hypothesis is: That the metal on metal articulations will not have better clinical outcomes than standard The resurfacing implant is expected to preserve the bone of the upper femoral bone. The implants are expected to be stabile within the first year.
Most children with cancer need a central venous catheter. These catheters are typically placed on the anterior thorax, where the risk of hypertrophic scarring and keloid development is greatly enhanced. A significant part of the children who have survived childhood cancer are troubled by their scars. Topical glucocorticoid treatment is known to induce a reduction of the collagen in the connective tissue. The investigators hypothesize that treatment with topical glucocorticoids for one week before and three weeks after removal of a central venous catheter, will reduce the formation of hypertrophic scarring and keloid development in children.
The aim of this study is to assess whether increasing oral doses of Riociguat are safe and improve the well-being, symptoms and outcome in patients with pulmonary hypertension associated with left ventricular systolic dysfunction
A randomized clinical trial of transcatheter aortic valve implantation (TAVI) versus conventional surgical aortic valve replacement (SAVR) in patients older than 70 years of age suffering from severe aortic valve stenosis. Study hypothesis: TAVI will reduce post-interventional morbidity and mortality compared to SAVR.
Increasing ("boosting") the radiation dose for patients with non-small cell lung carcinoma to the individual maximal dose which can safely be given. The question is if patients should receive this boost on the whole tumor on part of the tumor. Therefore patients are randomized for one of these two treatment options. All patients will receive 24 radiations. Dose increasement will be enabled by a so called integrated boost. Furthermore: - PET imaging of hypoxia using [18F]HX4, single injection and then PET CT scanning two and four hours post injection.
Hypothesis: during fasting and exercise will there be an activation of sirtuins (Sirt1). Primarily the investigators will investigate Sirt1 activity in muscle- and fat-biopsies after fasting for 36 hours and after 1 hour of ergometer-cycling at 50 Vo2max. In addition to this the investigators will investigate the effect of fasting and exercise on the velocity of carbamide synthesis, aminoacid rate of turnover and glucose rate of turnover.
Aim of the study: To investigate if the intervention described in this protocol has an effect on patients' and staff's physical health. Null hypothesis: There is no difference in waist circumference, body weight, quality of life and the rate of polypharmacy between the intervention and control groups after six months.
The aim is to study the effects of flaxseed mucilage, rich in dietary fiber on apparent fat and energy digestibility in young adults.
Should we, or should we not, perform dilatation of the side branch through the main vessel stent, if there is acceptable blood flow in the side branch?
