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.
Oxygen treatment is widely used in acutely ill patients, both pre-hospital and in hospital. The indication for oxygen is sometimes unquestionable, such as in many hypoxic patients, but in other situations its use is more of a practise and much less based on scientific evidence. In particular, oxygen treatment is routinely used in patients with a suspected heart attack and variably recommended in guidelines, despite very limited data supporting a beneficial effect. Indeed, a few studies even indicate that oxygen treatment might be harmful. Immediate re-opening of the acutely blocked artery to the heart muscle is the treatment of choice to limit permanent injury. However, the sudden re-initiation of blood flow achieved with primary percutaneous coronary intervention (PCI), the reopening and stenting of the blocked vessel, can give rise to further endothelial and myocardial damage, so-called reperfusion injury. Ischemia and reperfusion associated myocardial injury (IR-injury) involves a wide range of pathological processes. Vascular leakage, activation of cell death programs, thrombocytes and white blood cells leading to extended inflammation and formation of clots are examples of those effects. The role of oxygen treatment on these pathological processes, on the extent of IR-injury and the final infarct size in patients with acute myocardial infarctions (AMI) has not previously been studied. In an ongoing national multicentre, randomized, registry based clinical trial, the DETO2X-AMI trial (NCT01787110), the effect of oxygen on morbidity and mortality in ACS patients is being investigated. The present DETO2X-biomarkers study is a substudy of the DETO2X-AMI trial, evaluating the effect of oxygen treatment on biological systems involved in the pathogenesis of reversible and irreversible myocardial damage and cell death in ACS.
The purpose of the study was to understand if there was benefit in continued treatment with a medicine called enzalutamide, when starting treatment with docetaxel and prednisolone (a standard chemotherapy for prostate cancer), after the prostate cancer had gotten worse when treated with enzalutamide alone.
Oxygen treatment is widely used in acutely ill patients. In particular, oxygen treatment is routinely used in acute coronary syndrome (ACS) patients with suspected acute myocardial infarction and variably recommended in ACS-guidelines, despite very limited data supporting a beneficial effect. Immediate re-opening of the acutely occluded infarct-related bloodvessel via primary percutaneous coronary intervention (PCI) is the treatment of choice to limit ischemic injury in the setting of ST-elevation ACS (STE-ACS). However, the sudden re-initiation of blood flow achieved with primary PCI can give rise to further damage, so-called reperfusion injury. Ischemia and reperfusion associated myocardial injury (IR-injury) involves a wide range of pathological processes. Vascular leakage, activation of cell death programs, transcriptional reprogramming, no reflow phenomenon and innate and adaptive immune activation all contribute to tissue damage, thereby determining the infarct size. The effect of oxygen treatment on these pathological processes, on the extent of IR-injury and the final infarct size in STE-ACS patients has not previously been studied. ACS is characterized by a systemic inflammation with typical elevations of soluble inflammatory markers as well as changes in white blood cells. The inflammatory reaction might be considered helpful in restoring myocardial tissue structure and function, but on the other hand it might worsen IR-injury by activating various pathological processes. In human experimental studies, Salmonella typhi vaccine has been used to create a standardized model of systemic inflammation and when administered to healthy volunteers the vaccination has not been associated with any adverse events. In an ongoing register randomized multicentre clinical trial, the DETO2X (Determination of role of oxygen in suspected acute myocardial infarction) study, the effect of oxygen on morbidity and mortality in ACS patients is being investigated. In a substudy of the DETO2X-trial, the investigators have planned to evaluate the effect of oxygen treatment on IR-injury in STE-ACS as assessed by biomarkers reflecting various aspects of the pathological processes involved. The presented study is an experimental pilot study performed in healthy volunteers with a Salmonella typhi vaccine-induced inflammation with the purpose of studying effects of oxygen treatment on biological systems involved in the pathogenesis of IR- injury.
Three endotracheal tubes (ETTs) with different surfaces properties will be studied regarding formation and structure of the biofilm formed on those ETTs. Cultures from oropharynx and tracheal secretions as well as pieces of the ETT will be examined. Findings from electron microscopy (EM) and microbiology will be analyzed and compared in respect to the three materials.
The purpose of this study is to observe and evaluate the use of a relapse prevention program over time among internet help-seekers. Participants are recruited via a nationally known portal for assisting anonymous individuals with changing their problematic alcohol use in a healthier direction (alkoholhjalpen.se). The intervention offered lasts 10 weeks and includes 7 relapse prevention modules, with a three-week pause between the 6th and 7th modules. Baseline data are collected regarding substance use and psychosocial health and follow-up takes place 10 weeks after recruitment. The study is observational.
An open study evaluating the sensitivity and specificity of a microwave-based device, Medfield Strokefinder MD100, to detect chronic subdural hematoma, by comparing measurements on patients recruited for surgery of chronic subdural hematoma to an age- and gender-matched group of healthy volunteers.
The goal of the clinical investigation is to reduce phantom limb pain (PLP), painful condition affecting 70% of amputees, so as to improve these patients' quality of life.
The last ten years sexually transmitted infections (STI) have substantially increased among adolescents. STI can lead to individual suffering and have a negative effect on the future reproductive health and also increase the need for health care, thus it is important to reduce the number of STIs. HPV vaccination is included in the school-based vaccination program since 2012, a catch-up vaccination is offered to older girls and young women aged 13-25. School nurses have a key role regarding information about HPV and HPV vaccine, and the school-based vaccination program has a substantial higher coverage rate. Knowledge is an important factor associated with attitude to preventive methods against HPV. In previous studies the results indicate that young people have low awareness of HPV and the HPV vaccine. Interventions can decrease sexual risk taking and influence the intention to receive HPV vaccination and increase the use of condom. The aim of this study is to increase primary prevention of human papillomavirus (HPV) by promoting HPV vaccination and increase condom use among upper secondary students. The aim is also to increase the knowledge about HPV, risk and prevention.
This registry is a prospective, non-interventional, post authorisation safety study for patients diagnosed with Transfusion Dependent, IPSS low or intermediate-1-Risk Myelodysplastic Syndrome (MDS), associated to a single abnormality of the chromosome 5 [del(5q)]. The purpose of this study is to collect additional data about the safety of an oral drug (lenalidomide, Revlimid®) that may have been prescribed to relieve anemia and decrease the need of blood transfusions. However, also patients affected by the MDS del(5q) who receive other treatments different from lenalidomide can be included in this study, if they agree.
This study is a double-blind randomized, placebo-controlled, parallel-group, 12 week study performed in up to 5 centres in Sweden to assess the effect of Omega-3 carboxylic acids and dapagliflozin on liver fat in patients with Type 2 diabetes with fatty liver (>5.5% as measured with magnetic resonance imaging (MRI))
