There are about 8563 clinical studies being (or have been) conducted in Sweden. 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.
Comparison of Fractional Flow Reserve versus instant Wave-Free Ratio for assessment of coronary artery stenosis severity in routine practice - To compare FFR to iFR in arbitrary consecutive patients referred for percutaneous coronary intervention (PCI). - To investigate the influence of hyperemia on iFR. - To test reproducibility of iFR and FFR.
The study investigates if applying a special ventilatory strategy during anesthesia for laparoscopic gastric by pass, produces less atelectasis and better oxygenation in spite of using 100 % oxygen during pre oxygenation and induction of anesthesia. The study investigates oxygenation with blood gas samples but also with a new method that might give more information without the use of blood gas samples. Primary: Oxygenation in patients with morbid obesity improves if preoxygenation, induction and maintenance of anesthesia is performed with either a continuous positive airway pressure (CPAP) or a positive end expiratory pressure (PEEP), respectively, of 10 cm H2O, in comparison to a technique without CPAP but with a PEEP of 10 cm H2O. Secondary: The improved oxygenation during anesthesia can be prolonged inte the postoperative period if emergence from anesthesia is performed without high levels of oxygen.
Currently the 3-year disease free survival of patients with locally advanced rectal cancer is about 50%. Current standard treatment for patients at high risk of failing locally and/or systemically includes pre-operative long course radiotherapy (5 weeks) in combination with chemotherapy (so called neoadjuvant chemoradiotherapy). The neoadjuvant chemoradiotherapy has been demonstrated to improve local control, but had no effect on the overall survival. Different studies in patients with rectal cancer studying the effect of adjuvant post operative chemotherapy did not result in an improved survival. This may be due the fact that rectal cancer surgery (TME) is associated with a high complication rate so substantial proportion of patients cannot receive chemotherapy postoperatively. An alternative approach is to administer the systemic therapy preoperative. To guarantee control of the rectum tumor short-course radiotherapy (5 days) is given, as different studies showed local control of the tumor for a long time. During this waiting period the patient is in a good condition to receive an optimal dose of chemotherapy. The investigators hypothesize that with this proposed protocol both the local tumour and possible micrometastases are effectively treated and that this will result in an increased survival. The investigators will compare this with the standard treatment of neoadjuvant chemoradiation followed by TME surgery and optional adjuvant chemotherapy.
Duchenne/Becker muscular dystrophy (DBMD) is a genetic disorder that develops in boys. It is caused by a mutation in the gene for dystrophin, a protein that is important for maintaining normal muscle structure and function. Loss of dystrophin causes muscle fragility that leads to weakness and loss of walking ability during childhood and teenage years. A specific type of mutation, called a nonsense (premature stop codon) mutation, is the cause of DBMD in approximately 10-15% of boys with the disease. Ataluren is an orally delivered, investigational drug that has the potential to overcome the effects of the nonsense mutation. This study comprises a Phase 3, open-label study of ataluren in participants with nmDBMD who previously received ataluren at an Investigator site in a prior PTC-sponsored clinical study. A separate open-label study (PTC124-GD-016-DMD; NCT01247207) is being conducted for nmDBMD participants who previously received ataluren at an Investigator site in the United States (US).
The optimal timing for surgical repair of traumatic rotator cuff tears is controversial. Today there are no prospective studies investigating the short to mid-term outcome after early arthroscopic repair of traumatic rotator cuff tears and the Swedish National Musculoskeletal Competence Centre requests more research to this subject. The investigators will follow 60 patients with acute rotator cuff tear undergoing early rotator cuff repair during the first year after surgery. The investigators hypothesise that the outcome after rotator cuff repair is good.
The objective of the study is in subjects with Insulin Treated Diabetes Mellitus type 1 or 2 and gastroparesis: - validate radiopaque markers with fluoroscopy with gastric scintigraphy method - study the difference of metabolic control including the frequents of hypoglycaemia, gastrointestinal symptoms, quality of life and nutrition state during dietary treatment of food of small particle size compared with food of large particle size - validate the radiopaque markers method and measurement of the blood glucose and gastrointestinal symptoms after a test meal, against the gastric scintigraphy - determine if the function of gastric emptying can be improved after intervention
The objective of the study is to find out if the medicine fesoterodine is a useful treatment in children with bladder muscle overactivity caused by a neurological condition. Children will be aged 6 to 17 years old. This is done by finding out how well it works, what the body does to fesoterodine, what side effects are experienced and the safety of fesoterodine. It will be compared with the medicine oxybutynin, which is already available for treating the condition.
This study aim to prospectively evaluate the clinical utility of Spyglass in sclerosing cholangitis patients undergoing endoscopic retrograde cholangiopancreaticography (ERCP). Fifty patients with a definite diagnosis of sclerosing cholangitis and a clinical indication for ERCP from September 2008 and onwards will be investigated with peroral cholangioscopy using Spyglass direct visualization system. Clinical data on all patients will be collected at time of the ERCP including information on the Primary sclerosing cholangitis (PSC) and inflammatory bowel disease (IBD), serum liver function tests and indication for ERCP. A structured data collection form including information on Majoie Score, macroscopic features of the bile ducts at cholangioscopy, quality of the investigation, technical difficulties, and an overall judgment of whether any abnormalities observed were benign or malignant was completed by the endoscopist in conjunction with the procedure.
The proposed phase II trial is a multicenter, randomized, open-label study that will evaluate the efficacy and safety of azacitidine alone or in combination with lenalidomide in high-risk Myelodysplastic Syndrome (MDS) or Acute Myeloid Leukemia (AML) with a karyotype including del(5q). The primary objective will be to evaluate the efficacy in terms of response according to International Working Group (IWG) criteria for MDS and AML after 6 cycles of azacitidine or azacitidine + lenalidomide treatment, or at end of study if this occurs at an earlier time point.
The purpose of this study within Caring sciences is to identify women with breast cancer who have stress symptoms and to offer these women appropriate care to reduce stress and increase well-being. This will be achieved by 1. Studying the prevalence of stress related symptoms in female patients with breast cancer 2. Testing the use of two short screening instruments to identify women at risk for developing long-standing stress symptoms 3. Studying the level and intensity of stress management interventions required to achieve increased well-being, using a stepped-care approach. 4. Studying the effects of interventions based on cognitive behavior therapy, delivered individually or in a group format. The hypothesis is that half of the individuals assigned to a low intensity intervention will be significantly improved after treatment. For individuals who continue to have symptoms after low intensity treatment it is hypothesized that continued treatment in a group setting with high intensity interventions will be more cost-effective. In addition the assumption is that reduction of stress symptoms in women with breast cancer will lead to a reduction in socio-economic costs.
