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.
There is increasing evidence that the pathophysiology of hepatic encephalopathy (HE) is tightly associated with low-grade cerebral edema. Uptake of ammonia in astrocytes leads to osmotic swelling caused by glutamine formation. Previous studies were performed in covert HE patients or used indirect methods. Methods: The investigators wish to describes quantitative measurement of localized water content using MRI water mapping in a cohort of patients with cirrhosis during an episode of overt HE type C and again after recovery. Furthermore patients with cirrhosis and no history of HE and healthy subjects will be investigated as controls.
Postoperative pulmonal complications (Abbreviation - PPC) after major abdominal surgery remains a significant clinical problem delaying rehabilitation after surgery. CPAP is one approach to minimize the frequency and severeness of PPC. In the investigators' organization intermittent mask CPAP every 2 hour, 15min, is used routineously after major abdominal surgery. Recently new devices has been designed, which give the opportunity tip deliver continuously CPAP with out interruptions because of presumed better comfort. Therefore better patient compliance. No studies to date have investigated the possible benefit of using continuously helm CPAP versus the traditional intermittent mask CPAP after major abdominal surgery. The investigators' study will investigate if there are any benefits with continuously Helm CPAP Versus intermittent Mask CPAP After Major Abdominal Surgery.
Severe necrotizing soft tissue infection (NSTI), including necrotizing fasciitis, is a life threatening infection that spreads quickly to cutis, sub-cutis, fasciae and muscles. Approximately 40% of all patients with infections caused by S. Pyogenes develop a streptococcal toxic-shock syndrome. In these cases the mortality rates exceed 40% in spite of adequate treatment with antimicrobials. Due to the rapid progress, the extensive damage on soft tissues and high risk of death, the microbes are called "flesh-eating bacteria". The present study is a spin-off of the larger EU funded INFECT study, looking at the experiences of patient and family to understand the impact on every day life. The present prospective mixed methods study has the potential to provide important knowledge regarding the occurrence of early signs and symptoms of NSTI, quality of life 6 and 24 months after diagnosis, and how the care and treatment can be optimized and organized in a person/patient and family centered way. The study also aims at validate the SF 36 questionnaire for this group of patients.
The overall aim of the study is to investigate if patients with musculoskeletal chronic pain have reduced semen quality in comparison with age matched healthy controls. Secondly, the aim is to investigate whether overweight with or without chronic pain are related to reduced semen quality. We will investigate semen quality in obese chronic pain patients, normal weight chronic pain patients and in obese and normal weight healthy controls.
The quality of colon cancer surgery is highly debated these years since the mortality of the disease is not declining markedly. Surgery is the main treatment of colon cancer and during surgery it is very important for the surgeon to remove the tumour and all potential ways of tumour spread. As colon cancer first of all spreads to the nearby lymph nodes lying along the tumour feeding artery the surgeon aims to cut the vessel as central as possible. This means that all of the tumour feeding artery should have been removed after surgery. In this study the investigators want to measure the length of the tumour feeding artery after surgery as a quality control of the surgery. The investigators hypothesize that the artery will be shorter than 5 mm. The investigators wish to CT scan all patients two days after colon cancer surgery and afterwards measure then length of the artery on the images. This study will not inflict with the normal routine for patient information and treatment.
The investigators want to investigate if patients with Oculopharyngeal Muscular Dystrophy can improve fitness by home-training on a cycle ergometer 30 minute, 3 times a week for 10 weeks. Participants will be evaluated on maximal oxygen consumption and maximal workload measured by an incremental test at baseline and at the end of the exercise period.
Since finishing the sequencing of the human genome in 2003, genetic research in coronary artery disease (CAD) and other complex traits have developed dramatically. Recent genome-wide association studies have identified a considerable number of common genetic variants each associated with the disease. This has led to a new understanding but also to the discovery of new therapeutical targets. However, each of the variants discovered only have minor effects on disease development and even the pooling of the variants only explains a minor percentage of the total heritability. It has been evident that rare or private mutations probably play a great role in the genetic architecture of CAD, especially among young and severely affected patients. These may only be identified by sequencing. Therefore, the investigators hypothesize, that the use of exome sequencing (the read-off of the entire protein-coding regions of the genome) and linkage analysis in families of extreme phenotype cases, will identify disease-causing genetic variants. From the West Denmark Heart Registry the investigators will enroll a minimum of 120 patients with atherosclerosis who have undergone a coronary artery revascularization procedure before the age of 40, to participate in study part 1. A pedigree analysis will be performed and cardiovascular (CVD) risk factors and current preventive treatment will be evaluated. 1. degree relatives aged 30-65 years, who are free of CAD, are invited to participate in study 2. CVD risk factors are evaluated as well as a CT coronary angiogram is performed to quantify the degree of asymptomatic coronary atherosclerosis. Families from study 1 and 2, who are considered severely affected by atherosclerosis, evaluated on a basis of family size, number of affected and severity of disease, will be selected for exome sequencing. Other relevant family members will be included as well as their CVD risk factors will be evaluated. Exome sequencing will be performed and variants found will be filtered on a basis of frequency, linkage analysis, gene position, existing knowledge and in-silico prediction tools. Possible findings will be validated by Sanger-sequencing and causality of new variants will subsequently be sought to be proven by relevant experimental studies.
The aim of this experiment is to investigate if intake of stevioside in addition to a carbohydrate-containing composition after work related depletion of muscle glycogen will increase the rate of glycogen re-synthesis as compared with intake of the carbohydrate-containing composition alone.
In order to assess circulating biomarkers of cardiovascular risk, we will conduct a 10-year follow-up study comparing 32 exposed (women with a history of pregnancy complicated by preeclampsia) and 32 unexposed (women with a history of uncomplicated pregnancy). Participants will be recruited from a well-characterised cohort, previously assembled during their pregnancies, at the Department of Obstetrics at Randers Regional Hospital in 2001-2004. Blood and urine samples, collected during their pregnancies, are stored in a biobank, thus rendering the possibility of longitudinal assessment.
This prospective, open randomized phase III surgical trial seeks to study whether radical prostatectomy (with or without the combination of external radiation) improves prostate-cancer specific survival in comparison with primary radiation treatment and hormonal treatment among patients diagnosed with locally advanced (T3) prostate cancer. Untreated or conservatively treated locally advanced prostate cancer is associated with high mortality. Modern curative treatment for advanced solid malign tumors include surgery and/or radiation plus attempted chemotherapy if available to achieve both local control and elimination of potential micro metastases. Whereas there is evidence that surgery can cure localized prostate cancer, there are no clinical trials of multi-modal treatment of locally advanced prostate cancer that includes surgical removal of the prostate. One potential advantage of adding prostatectomy to the treatment of LAPC is that removing the prostate enables a full pathological assessment of the tumor characteristics and thus a better estimation of the risk of recurrence. Surgical treatment could thus reduce the numbers needed to treat with chemotherapy and radiation, and thus improve quality of life after treatment. In addition, evidence indicate that residual cancer in the prostate occurs in 25% after radiation treatment (56) and surgical removal of the prostate may improve survival beyond what can be achieved by radiation and ADT. On the other hand, patients treated with surgery, radiation and hormones will experience side effects of all three treatment modalities and might fare better if radiotherapy plus hormones can provide oncological control without prior surgery. A randomized clinical trial comparing two multimodal treatment regimens of which one includes a radical prostatectomy is therefore warranted.
