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 increasing interest in probiotic lactobacilli in health maintenance has raised the question of potential risks. One possible side effect could be an increased acidogenicity in dental plaque. The aim of this study was to investigate the effect of probiotic lactobacilli on plaque lactic acid (LA) production in vitro and in vivo. Methods. subjects (n=18) were given lozenges with probiotic lactobacilli (L. reuteri DSM 17938 and ATCC PTA 5289) or placebo for two weeks in a double-blinded, randomized cross-over trial. The concentration of LA in supragingival plaque samples was determined at baseline and after 2 weeks. Salivary counts of mutans streptococci (MS) and lactobacilli were estimated with chair-side methods.
The overall purpose is to explore the link between the gut and the bones by investigating meal stimulated changes in the blood level of a number of hormones and markers related to intestinal growth and bone turnover in patients undergoing surgery for obesity (gastric bypass). The hormones will be measured in blood samples taken before and after surgery. The results are compared with changes in body weight and body composition as measured by DEXA scanning.
Patients with chronic obstructive pulmonary disease, also known as COPD or emphysema, is like any other with a chronic illness not only affected by the physical discomfort the illness gives. For COPD patients that is: accelerated loss of lung function, conditioning and increased mortality: 25% of patients hospitalized with COPD exacerbation die 12 months later. Patients are also characterized by various psychological factors such as reduced quality of life, depression, etc. Therefore, everywhere in the country newly diagnosed COPD patients are offered rehabilitation in Region Zealand which consists of 10 weeks of classes 2 hours, 2 times a week with physical exercise, smoking cessation, medication, nutrition education and psychosocial support and patient education based on the National Health Service and international recommendations. In the literature, the effect of rehabilitation on quality of life was measured using a questionnaire (St. George Respiratory Questionnaire (SGRQ)), and the increase in function has been measured using a walk test, but there are no studies which look at the effect on inflammation lungs. It is important for COPD patients is to prevent exacerbations of the disease, which sometimes requires hospitalization and sometimes treated by their own doctor. It has been proven that inflammation in the lungs is associated with disease severity and exacerbation frequency, and therefore we would like to investigate whether both rehabilitation, close monitoring of patients with time in the pulmonary clinic every 3 months, and instruction in self-administration of medication (antibiotics and corticosteroids) have an effect on especially inflammation in the lungs, number of exacerbations, mortality, lung function and walking capacity.
This is a multi-center, open-label, single-sequence, crossover, drug-drug interaction (DDI) study to assess the effect of the CYP1A2 inhibitor, fluvoxamine, on the PK of dovitinib in patients with advanced solid tumors, excluding breast cancer. The purpose of this study is to evaluate the effect of a CYP1A2 inhibitor, 100 mg fluvoxamine, on the PK of dovitinib when administered at a dose of 300 mg on the dosing schedule, 5 days on/2 days off. The study will consist of 2 phases: a Pharmacokinetic (PK) phase and a clinical treatment phase. The DDI test will be conducted in the PK phase. The DDI test will assess the steady state PK profile of dovitinib when administered alone and in the presence of the CYP1A2 inhibitor, fluvoxamine (AUC 0-24h, AUC 0-72h and Cmax parameters). During the clinical treatment phase patients may continue to receive treatment with TKI258 until disease progression (assessed by RECIST 1.1), unacceptable toxicity, death or discontinuation from the study treatment for any other reason.
The study compares two different operative techniques for placement of the Cochlear Bi300 implant to be used for bone anchored hearing aid. The operative techniques to be compared are - Dermatome technique with soft tissue reduction - Linear incision with minimal or no soft tissue reduction The hypothesis is that the operative techniques are comparable with regard to implant stability, soft tissue healing and loss of sensibility around the implant. To evaluate the evolution of implant stability during the early healing period after implantation, which is the most critical period for osseointegrated implants, in particular when early loading protocols are used. To compare soft tissue healing around Baha implants placed according to the recommended surgical technique with skin transplant and Baha implants without performing skin reduction. To compare the loss of sensibility of the skin around the Baha implant (some loss of cutaneous sensibility nerves in the transplant procedure) between the two surgical procedures. While the study focuses on the early healing period (3 months), long-term safety data will also be collected after 6 months and 1-year. The study will also evaluate the change in health status produced by the surgical intervention.
The purpose of this study is to examine the effect of an educational video on intensity of neck pain, disability, illness perceptions and work ability following acute whiplash trauma caused by motor vehicle accidents.
The aim of this study is to evaluate whether an enhanced strategy of implementation of the new guideline will lower the number of patients getting referred to secondary care spine centres compared to a normal implementation strategy.
The purpose of this study is to assess the effect of reducing exposure to allergens in patients with hay fever by means of a nasal filter.
It is well known that continuous physical exercise leads to a number of changes in the body. Maximal oxygen uptake; the heart's pumping ability and muscle mass and strength increases. Also the metabolism adapts: The ability to oxidize fat increase and the insulin sensitivity in primarily in muscle, but also in the liver increase. Also endocrine glands adapts according to the level of physical activity. It is known that in healthy, younger people the insulin secretion from the pancreas after administration of sugar consumed orally or given directly into a vein, is significantly lower in trained individuals compared with untrained. This change does, however, not only apply to glucose, as also stimulation by the amino acid arginine, shows the same pattern. It seems plausible that the endocrine glands/cells adapts to the level of physical training, but this has not yet been investigated. The gastrointestinal tract is the birthplace of a variety of hormones. One group of these is called incretin hormones. They stimulate the glucose dependant insulin secretion in the pancreas and affect hunger/satiety. Whether the incretin production and thus their concentration in the blood is regulated by physical training is unknown. Obese and patients with type 2 diabetes, has, in contrast to well-trained, decreased insulin sensitivity. As a consequence their (type 2 diabetics, at least early in their disease course) meal stimulated insulin release is greater than in healthy, normal weight individuals. This in spite of the fact that the incretin effect is reduced in obese people and patients with type 2 diabetes compared to healthy, normal weight. Whether physical training affects both the secretion of incretins and the incretin effect has not yet been studied. The purpose of this study is to investigate whether incretin hormones in physical well-trained young men have a changed effect on insulin secretion from the pancreas compared to untrained young men. A difference may indicate that the body's endocrine glands adapts to training mode. The investigators hypothesis is that incretin hormones have a decreased effect on the glucose dependant insulin release in physically trained persons and thus results in a lower insulin release at any given plasma glucose level.
The purpose of the study is to examine the relationship between working capacity (peak oxygen consumption) and pump speed of continuous flow left ventricular assist devices (CF-LVADs)in heart failure patients. The hypothesis is that it is possible to increase peak oxygen consumption by incrementally increasing CF-LVAD pumpspeed during exercise. The study population will consist of severe heart failure patients with CF-LVADs treated at The Heart Centre of Copenhagen University Hospital Rigshospitalet.
