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.
Mutations in the SLC34A2 gene, that encodes the sodium phosphate co-transporter (NaPi-IIb), cause defect cell-uptake of phosphate, which leads to formation of calcium-phosphate concretions in the lungs as seen in Pulmonary Alveolar Microlithiasis (PAM). Extra pulmonary calcifications, including heart valve calcification, have previously been reported in patients with PAM. Calcific Aortic Valve Disease (CAVD) is a common disease in the elderly and is characterised by thickening and calcification of the aortic valve leaflets in the absence of rheumatic heart disease. CAVD is present in more than 25% of patients older than age 65 years and is associated with an increased risk of cardiovascular events. Currently, there is no effective therapy for the disease other than surgical aortic valve replacement. Both calcium and phosphate are the major components of calcific deposits in PAM and CAVD. Based on these preliminary findings, the investigators hypothesize that mutations in sodium phosphate co-transporters may play a role in both pulmonary and extra pulmonary calcifications. Two studies will be performed: 1. A retrospective cross-sectional study including patients with an age ≤ 65 years with CAVD from Denmark and Örebro, will be carried out. Genetic association analysis will be performed to investigate the incidence of common variants in five genes representing sodium phosphate co-transporters (SLC34A1, SLC34A2, SLC34A3, SLC20A1, SLC20A2) compared to healthy controls. Associated genes will subsequently be sequenced to identify possible causal mutations. 2. In a prospective study, aortic valve tissue will be collected from patients with AS undergoing surgical valve replacement. Molecular characterisation of the transporters will be conducted by determining the level of specific mRNA and protein by RT-PCR/qPCR, and Western Blotting, respectively. The localisation and visualisation will be investigated by immunostaining and confocal laser microscopy. Fibroblasts and endothelial cells will be isolated and grown in cultures with subsequent functional studies of the phosphate uptake.
The investigators aim to investigate whether low energy shockwave therapy (LE-SWT) can preserve kidney function in diabetic patients. Participants in this study will receive LE-SWT treatment 6 times over 3 weeks. The treatment is non-invasive and has no known side effects. Previous studies have shown that LE-SWT induces angiogenesis. The investigators hypothesize that chromium-ethylenediaminetetraacetic acid (EDTA) renal clearance remains stable or increases in treated patients. Furthermore, kidney biopsy should show no signs of damage to the tissue and possibly neo-vascularization. In this project, the investigators shall also investigate LE-SWT effect on urinary markers of tubular damage and urinary nitric oxide indices. Patients' self-reported quality of life will be assessed using Short Form 36 version 2 (SF-36v2) Health Survey. There is an 18-months follow-up on patients. Only patients between 18-65 years old with moderate chronic kidney failure from diabetes will be included. This project is an interventional prospective study. 30 patients with moderate kidney failure will be recruited from the Department of Endocrinology, Odense University Hospital, Denmark. LE-SWT treatment will be performed in the ambulatory of Department of Urology. Patients will be hospitalized for 1 day in the Department of Nephrology when kidney biopsy is taken (two times in study period).
The objective of the study is to investigate clinical outcomes following single versus dual stenting strategies for the treatment of true bifurcation distal left main coronary artery lesions.
Background: Phantom limb pain (PLP) develops in 50-80% of subjects who have a limb amputated. It is not well known what causes PLP to develop and the current treatments have been shown to be largely ineffective. Resent research, however, have indicated that cortical reorganizing occurring after amputation of the cortex areas related to the missing limb may be related to the development of PLP. Furthermore, the research indicated that by providing meaningful sensory input coming from the phantom limb the PLP may be alleviated and the cortical organization normalized. Aim: The CIP described in the current application, is part of a the EU-project "EPIONE", which aims to investigate if and how cortical normalization and PLP alleviation can be induced by providing phantom limb sensations (sensations which seems to originate from the missing limb) in hand amputated subjects. Method: In the current study, which will take place at Aalborg University Hospital (AUH), 2-4 hand amputated subjects experiencing severe PLP will implanted with interneural nerve electrodes in the arm stump for up to one year. Therapy will be evaluated in two stages, first during a standardized four week phase where the subject receives daily therapy. If the therapy is shown to be effective, therapy may be reinitiated during a second longer therapy phase. During the therapy sessions, selective nerve stimulation will be performed. The amputee will experience this as sensations (movement, touch, temperature, vibration etc.) originating from the phantom limb. While implanted, we will investigate how well we can induce these sensations and we will provide a stimulation therapy, which consist of stimulation activities which requires the subject to focus on the evoked sensations. Prior to, during a and following therapy a series of assessments (standardized across all EPIONE partners to enable comparison) will be conducted to relate therapy with PLP, cortical organization, the mental state etc. of the subject. Expected outcome: The stimulation therapy is expected to alleviate PLP and induce cortical normalization. The experience we gain might be used for deriving clinical guidelines on how to treat PLP.
Background: Non-alcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease in the western world and an important cause of morbidity and mortality including risk of cardiovascular disease. A ruling dogma is that a fatty liver is well-functioning. Recent studies imply the contrary but quantitative measurements of metabolic liver function have not been systematically investigated in NAFLD. Objectives: To study and quantify specific metabolic liver functions in varying degrees of NAFLD. Furthermore to map the coagulation system of patients with NAFLD. Methods: A human clinical study. Metabolic liver functions are studied by a series of functional tests (Galactose elimination capacity (GEC), Aminopyrine breath test (ABT), Indocyanine green plasma disappearance rate (ICG-PDR), Functional hepatic nitrogen clearance (FHNC)). Regional liver function evaluated by 2-[18F]fluoro-2-deoxy-D-galactose (FDGal) PET/CT is compared to fat infiltration assessed by Magnetic resonance imaging (MRI). Primary and secondary hemostasis, natural anti-coagulants and fibrinolysis are evaluated. Perspectives: To challenge the dogma, that hepatic metabolic function is not affected in NAFLD, improving the understanding of the relationship between the clinical degree of NAFLD, histology, metabolic functions, and imaging. Furthermore to disclose a proposed procoagulant imbalance in NAFLD.
The present study plans to delineate the clinical, biochemical, sociological and psychological factors. involved in dialysis preparation, and their impact on dialysis initiation (DI), modality choice and prognosis. In particular the following questions are to be answered. 1. What factors influence unplanned DI? 2. What factors influence choice of dialysis modality? 3. What factors influence choice of dialysis access? 4. Why do physicians start dialysis? 5. What factors in the predialytic period and its immediate aftermath (the "peridialytic" period) influence prognosis?
This study aim to evaluate the quality of fetal ultrasound in obese pregnant women. The hypotheses is that an early ultrasound will improve the quality of the ultrasound in obese.
Does comforting conversation during colonoscopy improve on patient satisfaction, compliance and pain management.
The study is a epidemiological, cross-sectional study in a mainly rural area of Denmark in Denmark. Life expectancy is shorter, morbidity is higher, and social problems more prevalent than in the urban areas of the country. The population study aims at examining complexities of environmental, hereditary, lifestyle, and social factors as determinants and predisposing factors for morbidity, health, and quality of life. The study will cover physical, mental, and social dimensions and examine family patterns and subgroups. The study will provide baseline information for later follow-up.
The purpose of the trial is to investigate the effects of three months' treatment with a CPAP-device versus control group on change in arterial stiffness in type 2 diabetes (T2D) patients with newly detected Obstructive Sleep Apnoea (OSA).
