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.
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 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.
This study is designed to assess bioequivalence between one test and one reference formulation used for temporary relief of pain. The results will help decide if the new medicine is likely to provide pain relief similar to the product being sold.
Overview and rationale: Through Swedish health care registers it is possible vaccine effectiveness. The overall aim is to develop tools for fast and reliable evaluation of vaccines focusing on effectiveness. In this study the investigators will assess the population impact on condyloma prescribed drugs after HPV-vaccination and to estimate the economic burden of hospitalizations due to condyloma. Genital warts (condyloma) are one of the most common sexually transmitted diseases in Sweden, estimated 20 000 identified cases per year, and are primarily treated with Podofyllotoxin and Immiquimod. One of the approved HPV vaccines also protects against condyloma. In clinical trials, this vaccine is safe and highly efficacious (90-100%) against persistent infection with HPV 6 and 11 and genital warts in women and men. However, these results are from clinical trials and do not answer the question weather the vaccine works when delivered, as it would be in the real world. By linkage between the Svevac, the patient register and the Drug prescription register the investigators can estimate the effectiveness of the HPV vaccine in preventing cases of condyloma in a defined population. Method and execution: This is a retrospective collection of data from Swedish health care registries where the study population will consist of persons who are HPV-vaccinated as well as a non-HPV-vaccinated control group (identified through the population-based register, matched on sex, age and living area). The primary statistical analysis will be a calculation of prescriptions of condyloma treatments after vaccination compared to the non-vaccinated control group.
