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.
This study assesses the 18-month incidence of inappropriate shocks in subjects implanted with the EMBLEM Subcutaneous Implantable Defibrillator (S-ICD) for primary prevention of sudden cardiac death. Devices are to be programmed with zone cutoffs at 200 bpm and 250 bmp in order to mimic the programming settings for transvenous ICDs in the MADIT RIT study. The incidence of inappropriate S-ICD shocks will be compared to the incidence of inappropriate shocks observed in the MADIT RIT study.
The key focus of this survey will be to collect data on physicians awareness of the content of the Pradaxa® Prescriber Guide and the extent to which risk awareness is communicated to patients. The data collected with atrial fibrillation patients will show if and how well this information is received and understood.
The incidence of malignity in the gastroesophageal junction (GEJ) is rising in Denmark, 400 new cases annually 1. 60% of the patients with GEJ cancer have disseminated disease (M1-stage) at time of diagnosis and are consequently unable to undergo curative intended surgery. The prognosis is poor, with 5-year survival rates of approximately 2 % for these 60% and the treatment only consists of palliative therapy 1. For the remaining approximately 40 % who are assessed as candidates for curative intended surgery, the 5-year survival rate is 33 % 1. This emphasizes the need for further research and knowledge concerning tumour biology and spontaneous course of the disease. In Denmark, all cancer patients are enrolled in a specific cancer program. The primary diagnostic work-up for GEJ cancers includes gastroscopy with biopsy, blood samples, ultrasonography scan, Positronemissionstomography (PET) and Computed tomography (CT) alone or PET/CT in combination 2. From these parameters physicians determine resectability and TNM-stage (tumour staging), which is substantial for the prognosis and future treatment. The primary goal is to achieve a macroscopically resection of tumour and lymphnodes in relation to the stomach and oesophagus (Esophagectomi a.m. Ivor Lewis and D1+ lymphadenectomy in the abdomen and thorax). In addition to surgery, patients receive perioperative chemotherapy, which consist of three series of chemotherapy preoperative and three series postoperative approximately 21-28 days after surgery. Approximately 12.6 % of patients receiving perioperative chemotherapy prior to surgery will have disease progression due to chemotherapy resistance during the therapy 3. This unintentionally leads to shifting these patients from the resectable group to non-resectable group (palliative treatment). Thus, the possibility for detecting response to perioperative chemotherapy is of great interest. A paradigm shift towards an individualised tailored therapy form has emerged in recent years, which potentially require a higher need for diagnosis on molecular level. Today most molecular biological methods apply tissue samples for in-vitro analyses, but new radiological tools provide opportunity for non-invasive examinations; for example PET can with a radioactive sugar compound: Flour-18 deoxyglucose (18F-FDG). This compound is injected through a catheter in a larger vein (media cubiti vein) and absorbed in cells with increased metabolism - especially cancer cells. A PET scanner registers the absorption; this radiology modality can provide valid information, which is essential for non-invasive tumour staging and monitoring response under a specific therapy. A new diagnostic modality is PET scan combinated with magnetic resonance (PET/MR) simultaneously. So far, no studies have conducted an evaluation of simultaneous PET/MR scan to assess the perioperative chemotherapy response in patients with GEJ cancer. However, some studies suggest that commercially available PET/MR scanner might contribute in a diagnostic elucidation 6. Simultaneous PET/MR scan might in theory minimize the misinterpretations of potential response changes after chemotherapy, which can appear in the interval between separate PET, CT and MR scans 4,5,7. Studies have found PET scan of GEJ cancer could be helpful as a prognostic tool to differentiate between responders and non-responders during chemotherapy 9. Standardized uptake value (SUV) is a unit that display the absorption of 18F-FDG and is used routinely to quantify tumour glucose metabolism in PET scan 8. A change of more than 35 % in SUV measurements before and after the induction of chemotherapy is considered as the definition of responders and non-responders in earlier studies 9. The MR technique is based on magnetic fields and radio waves. Diffusion Weighted Imaging (DWI) is a non-invasive MR-modality, which measures the changes in water diffusion (Brownian movements) throughout tissue. These changes are measured in Apparent Diffusion Coefficient (ADC), a parameter derived from DWI and reflects the change in diffusion 7. ADC and DWI can be used to differentiate between benign and malignant tumours, due to a larger cell density in malignant tumours. Consequently, malignant tissue has a decreased diffusion relative to normal tissue. ADC has been used as a factor in some studies to predict the response to chemotherapy 10. A single study has shown a rise in ADC-value two weeks after initiation of chemotherapy in patients with GEJ cancer, and demonstrated that the percentage change in ADC-value between the groups (responders and non-responders) is significantly different 11. Simultaneous PET- and MR scan might be very useful to evaluate the response to chemotherapy in patients with GEJ cancer compared with these parameters alone. The opportunity for a more individualised tailored treatment in future might be possible with PET/MR.
Background: Patients with the sugar metabolism disorder, Glycogen Storage Disease Type V, have insufficient breakdown of sugar stored as, glycogen, within the cells. The investigators know from previous studies with McArdle patients, that they not only have a reduced sugar metabolism, both also have problems in increasing their fat metabolism during exercise to fully compensate for the energy deficiency. Studies on Triheptanoin diet used in patients with other metabolic diseases have shown that Triheptanoin can increase metabolism of both fat and sugar. In these patients, Triheptanoin has had a positive effect on the physical performance and has reduces the level of symptoms experienced by patients. Aim: To investigate the effect of treatment with the dietary oil, Triheptanoin, in patients with McArdle disease on exercise capacity. Methods: 20-30 adult patients will be recruited through Rigshospitalet in Copenhagen, Denmark, Hopital Pitié-Sapêtrière in Paris, France and through The University of Texas Southwestern Medical Center in Dallas, Texas. 1. Pre-experimental testing (1 day): Baseline blood samples are collected to obtain baseline values of safety parameters: Plasma-acylcarnitines, free fatty acids and creatine kinase. Subjects perform a max-test to determine their VO2max 2. Treatment period #1 (2 weeks): Subjects follow a diet consuming a dietary treatment oil. Neither patients nor members of the study group know who receive which type of oil. 3. Washout period (1 week): Subjects receive no treatment 4. Treatment period #2 (2 weeks): Subjects who received Triheptanoin oil in the first treatment period, now receive placebo oil and vice versa. Assessments: Before and after each treatment periods, subjects perform a 30-minutes exercise test on a cycle ergometer, comprising of 20-22 minutes of constant load exercise and 6-8 minutes increasing load to peak. Subjects will complete a Fatigue Severity Scale questionnaire and metabolic products will be measured in blood and urine.
Prostate cancer is the most common malignancy in men. Three million are currently living in the United States with the disease and this number is expected to rise to four million in 2024. Most live many years with the disease and experience significant morbidity both due to disease progression and treatment toxicity. Exercise has shown to improve QoL and reduce treatment toxicity. Moreover epidemiological evidence has suggested that physical activity improves survival. Football has been shown to induce positive effects on body composition and bone markers in a subgroup of prostate cancer patients, those receiving androgen deprivation therapy. The objective is to examine the effectiveness of football in prostate cancer survivors.
The aim of this project is to investigate the pathophysiology of PCOS in regards to the metabolic profile including defects in insulin sensitivity in skeletal muscle and adipose tissue, and to investigate the effects of exercise training on these parameters.
Some patients experience a degree of pain and discomfort during endoscopic examination of the large bowel. Sedatives and analgesics may be administered in low doses. Excessive dosage or intense pain may lead to hypotension and impaired level of consciousness. The purpose of the present study was to determine if simulation training of endoscopy staff in preventing pain and handling acute complications through effective teamwork could improve the quality of colonoscopy from the patients' perspective.
