There are about 5161 clinical studies being (or have been) conducted in Norway. 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 aim of this study is to compare short term (3 week) with long term (6 months) treatment with seton prior to LIFT surgery. The main end-points are recurrence rates and complication rates after surgery.
Hypothesis: Deferasirox can be used as a therapeutic agent to deplete the liver, heart and bone marrow of excess iron in patients with iron overload caused by myelodysplastic syndrome (MDS) and hemochromatosis (HC. Assess the effect of new serum biomarkers (NTBI and hepcidin) and MRI as indicators of iron overload and their usefulness to monitor iron depletion treatment. Study the effect of iron overload and iron depletion on intracellular signal transduction, trace metals concentrations in serum and urine and markers of oxidative stress in blood cells and urine.
Ulcerative colitis (UC) is an inflammatory disease involving the colonic mucosa, with bleedings and ulcerations. Consequences are destroyed mucosal barrier and increased permeability. Several cytokines are described to mediate the progressive course of ulcerative colitis and it is considered nowadays an immunologic disease. Patients with UC have often low levels of vitamin D and elevated prevalence of osteoporosis. In vitro studies demonstrate that vitamin D has an immunomodulating effect, and may have a direct healing action on colonic mucosa has been described in animal studies. One can therefore rise a hypothesis that vitamin D supplementation could be crucial in patients with UC. To our knowledge, it has not been performed randomized clinical trials to study these possible effects of vitamin D and it has not been studied the effects of vitamin D on the relapse frequency and immunological composition of colic mucosa in patient with moderate to severe ulcerative colitis. Objectives for our study are as follows: To examine if high-dose vitamin D supplementation in patients with moderate to severe ulcerative colitis: - reduces relapse frequency and increase the duration of the Infliximab induced remission - mediates and changes the cytokines composition in the colic mucosa - decreases the excretion of calprotectin in feces and reduces the concentration of inflammation markers - augments bone mass
The purpose of this study is to determine whether tactile stimulation for reduced sensibility of the affected extremities after stroke has effect. Hypothesis: Stimulation of sensibility after stroke will have a significant contribution for improved sensibility. Without any stimulation, no signal is sent to the brain and there is no need for the healthy parts of the brain to adapt this function. Stimulation of the sensibility over a period of time on both sides of the body, gives the brain signals and the opportunity to compare how the signals should be recognized. New connection will be able to interpret signals correctly.
This study is the radiological component of an earlier registered trial under the title: Efficacy of Exercise on Physical Function and Cartilage Health in Patients With Knee Osteoarthritis. The main purpose in this component of the study is to evaluate the efficacy of aerobic exercise and strength training on the T2 and T1 rho relaxation times of the articular cartilage. It has been proven that exercise can improve function and reduce the need for analgesics in patients with osteoarthritis. With this study, we wish to investigate if different kinds of exercise can cause measurable improvements in T2 and T1 rho relaxation times of the articular cartilage, and also if this improvements are transient or permanent.
The investigators will evaluate the accuracy of performing cytological imprints of targeted biopsies when diagnosing prostate cancer. It is useful to know whether the biopsy is cancer or not, in order to know when to stop sampling and when to continue. The strategy is used in other types of cancer, e.g lung, breast etc
This study looks at advanced airway management in critically ill or injured patients treated by physician manned emergency medical services, comparing early (on-scene) intubation to late (emergency department) intubation.
The study will examine the role of adipose tissue in vitamin D physiology, particularly its role as a depot. the study is randomized double blind and placebo controlled.
The main object to this trial is to study the function of referral letters as a mean to coordinate the care process for adult people when referred from Primary Care to Specialised Mental Health Care. The study will explore if and to what degree the quality of these referral letters can be improved, and the potential improvement's impact on defined patient-, professional and organisational related outcomes. According to Medical Research Council guidelines for evaluating complex interventions, a stepwise design with the use of both qualitative and quantitative methods will be used to conduct a controlled intervention study.
Exposure to noxious gases and particles is associated with an increased prevalence of respiratory and cardiovascular diseases. Thus, investigation of possible airway inflammation and/or systemic inflammation in workers exposed to high levels of dust is important. Silicon Carbide (SiC) Processing Inc. provides cutting fluid (slurry) for the production of solar cells and is at present the largest provider of slurry to the solar industry worldwide. In the production process, the recyclable materials (SiC), polyethylene glycol (PEG)) of the used slurry are recovered. The airborne exposure consists mainly of SiC (dust particles) and evaporation from the recycling of PEG. High levels of dust have been measured and, seventeen per cent of the measurements in the processing hall were equal to or higher than the Norwegian occupational exposure limit. Thus, assessment of possible systemic and airway effects of this exposure is of interest. A prospective design will be applied and the effects studied by means of registration of respiratory symptoms, spirometry, nitric oxide (NO) in exhaled air, induced sputum and blood sampling over a 3 year period. Exposed subjects will also be compare with non- or low exposed subjects (administrative/office workers). Efforts will be made to include all eligible subjects and to avoid drop-outs. If early signs of airway or systemic inflammation in workers or in cells are demonstrated in the study, it will be necessary to implement measures to reduce the exposure levels. The primary aim of the present study of workers exposed to Silicon Carbide dust in the workplace is to determine whether this exposure is associated with inflammatory changes in the lungs. The secondary aims are: - to examine possible changes in systemic inflammatory markers and - to examine changes in lung function among Silicon Carbide processing workers during a period of 3 years. Possible changes in lung function will be monitored by spirometry and gas diffusion measurements (study A). Airway inflammatory responses and changes in circulating inflammatory markers will be assessed by examination of the induced sputum samples and blood samples every 6th month in a subgroup of workers (study B).
