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.
Trauma is the leading cause of death among persons below 60 years of age. It is a well-established belief that optimal treatment in the early phase after trauma has a major impact on mortality, and the implementation of specific educational programs for trauma care have been a widely adopted strategy aimed at improving the outcome. This strategy has high face validity, but the underlying evidence is poor. The Prehospital Trauma Life Support (PHTLS) program was introduced in 1983 aiming to integrate prehospital trauma care with the Advanced Trauma Life Support (ATLS) program. Approximately half a million prehospital caregivers in over 50 countries have taken the PHTLS course. It has been recognized as one of the leading educational programs for prehospital emergency trauma care. However, the scientific support for improved patient outcome from courses such as PHTLS and ATLS is limited. According to a Cochrane analysis published 2010 there is no evidence to recommend advanced life-support (ALS) training for ambulance crews. Another Cochrane analysis concerning ATLS gave similar results and a recent study indicated even worsened outcome after the implementation of ATLS. An observational study in the county of Uppsala indicated reduced mortality after the implementation of PHTLS but the estimate was uncertain due to a low overall mortality. The aim of this study is to further investigate the association between PHTLS training of ambulance crew members and the outcome in trauma patients in a larger study population. To accomplish this the investigators will use an epidemiological semi-individual design applied to all victims of traffic injury that occurred during the implementation period of the PHTLS course in Sweden (1998-2004). Four outcomes and subsets of patients will be analyzed: Mortality before hospital admission, mortality within 30 days, time to death among survivors to hospital admission and return to work among survivors to hospital discharge.
Mortality and incidence of severe complications is still high among extremely premature infants. Common causes of severe complications in this population are poor nutrition, necrotizing enterocolitis, and severe infections. Feeding intolerance is also a common problem resulting in prolonged need for intravenous lines and poor nutrition. The aim of the study is to evaluate whether supplementation with the probiotic bacterium Lactobacillus reuteri DSM 17938 daily to premature infants with extremely low birth weight increases feeding tolerance to breast milk and thereby improves nutrition, increases growth and reduces serious complications and mortality in this population. Beyond this, possible mechanisms underlying these effects will be analyzed in stool, breast milk and blood samples.
Gastric emptying is the end-result of a complex and carefully regulated series of events which follow the ingestion of a meal, each of which is dependent on the other and subject to neurohormonal control. Motilin is an endogenous peptide, produced mainly in the duodenum, whose physiological action is mediated by motilin receptors located on enteric neurons, peripheral terminals of the vagus, and on the smooth muscle of the gut. Motilin and non-peptide agonists at motilin receptors increases the gastric emptying rate and therefore provide a potential approach to the treatment of a range of clinical conditions in which delayed gastric emptying is thought to be part of the physiopathology and may be contributory to symptoms. Parkinson's disease (PD) is a progressive neurodegenerative disorder characterized by degeneration of nigrostriatal dopaminergic neurones. It affects 1.5% of the global population over 65 years of age. Cardinal symptoms comprise bradykinesia, rigidity, resting tremors and postural instability. Gastrointestinal dysfunction, including gastroparesis, is a frequent feature of PD affecting approximately 90% of patients, and is caused by autonomic dysfunction as well as an adverse effect of antiparkinsonian drug therapy. The therapeutic mainstay for PD treatment is the neutral amino acid L-3,4-dihydroxyphenylalanine (L-DOPA), a dopamine prodrug, as it provides the most rapid and effective symptomatic control of motor impairment in PD. The primary determinant of L-DOPA bioavailability is gastric emptying (GE); delays in GE slow delivery of L-DOPA to its proximal small intestinal absorption sites, increasing the extent of presystemic metabolism, and leading to slowed and diminished absorption.
This is an observational study, hence there is no study hypothesis
The purpose of this study is to determine whether BMS-823778 is safe and effective in the treatment of hypertension in overweight and obese patients.
Achalasia is a rare neurodegenerative esophageal motility disorder characterized by incomplete lower esophageal sphincter (LES) relaxation, increased LES tone, and aperistalsis of the esophagus leading to dysphagia, regurgitation, and chest pain. therapies for achalasia consist of endoscopic balloon dilatation (EBD) and botulinum toxin injection (EBTI), or surgical Treatment via i Heller Myotomy; surgery is nowadays mostly performed via the laparoscopic approach. Surgical therapy demonstrated superior treatment efficacy compared to EBD and EBTI. Recently, an endoscopic means to perform myotomy via a submucosal tunnel has been developed, namely PerOral Endoscopic Myotomy (POEM). Uncontrolled studies have indicated a symptomatic success rate of >90% for POEM in short term follow-ups.The aim of this study is to compare short and long-term feasibility, safety and efficacy of endoscopic (POEM) with laparoscopic myotomy (Heller myotomy) in the treatment of achalasia.
The study is undertaken to investigate if the urethral microtrauma, caused by intermittent catheterization, differs between three hydrophilic catheters for intermittent catheterization, LoFric; SpeediCath (SC) and SpeediCath Compact Male (SCCM). The study is a prospective, randomised, cross-over, single-centre study. Each subject will be randomized to use three different catheter types. Three catheterizations will be performed with each catheter type during one day, with at least two hours between each catheterization. The washout period between catheter switch will be at least one week. The primary objective is to evaluate urethral microtrauma for three hydrophilic catheters with regards to hematuria after intermittent catheterization. The secondary objectives are to evaluate urethral microtrauma for three hydrophilic catheters with regards to pyuria and subjective evaluation after intermittent catheterization. The safety of the three catheters will be evaluated in terms of adverse advents, non-serious and serious, rated for causality. The hypothesis that level of hematuria is equal after using different catheters will be tested using Wilcoxon signed rank test. The hypothesis will be rejected if the p-value is less than 5%.
This study will generate comparative data for 0.5-mg ranibizumab using PRN dosing administered with or without adjunctive laser treatment versus laser photocoagulation (the current standard of care) up to Month 6 in patients with visual impairment due to ME secondary to BRVO. Additionally the results of this study will provide long-term (24-month) safety and efficacy data for ranibizumab, administered with or without adjunctive laser treatment in this indication.
Primary mediastinal large B cell lymphoma is treated with a combination of chemotherapy and the monoclonal antibody rituximab (chemoimmunotherapy). Following chemoimmunotherapy patients receive radiation therapy if they have residues which may be active tumour. However at the end of chemoimmunotherapy the majority of patients show tissue scarring that is not necessarily active tumor. In recent years, PET/CT has proved to be a good tool to accurately identify active tumor from scar tissue in patients treated for mediastinal lymphoma.The purpose of this trial is to test whether radiation therapy is really necessary in patients where PET/CT has shown that the tumor is no longer active. Therefore we will compare radiation treatment with careful observation. Patients that at the end of conventional treatment of chemoimmunotherapy have a negative PET/CT (i.e., without residues suspected to contain active tumor), will randomly assigned to two different treatment groups: one treatment group will receive the radiation treatment, and the other treatment group will receive careful observation. The trial is planned according to a non-inferiority design aimed at demonstrating that progression free survival after the experimental treatment (observation) is not worse than after the standard comparator (mediastinal irradiation.Participation in this study could spare patients with complete remission at the end of chemo immunotherapy (PET/CT negative) radiation therapy that may be unnecessary.
