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.
The overall project aim is to study children's neurodevelopmental outcomes (including diagnoses of autism, ADHD, and intellectual disability) following exposure to maternal anemia during pregnancy or anemia during the first year of life using national and regional Swedish health-data registers, and to assess children's neurodevelopmental outcomes over the range of maternal hemoglobin levels during pregnancy.
The goal of this double blind randomized placebo-controlled clinical trial is to compare intranasal oxytocin and placebo in young adult individuals with alcohol use disorder as compared to healthy controls. The main questions it aims to answer are: - The effect of oxytocin versus placebo on prosocial behavior in individuals with high- versus low alcohol use - The effect of oxytocin versus placebo on impulsivity, emotion recognition, social learning, and alcohol craving in individuals with high- versus low alcohol use Participants in both groups will on two separate visits perform the following validated behavioral task measures: - Dictator game tasks assessing prosocial behavior - Delay discounting task assessing impulsivity - Emotion recognition task assessing emotion recognition - Alcohol cue craving task assessing alcohol craving - Observational fear learning task assessing social learning Researchers will compare groups of high and low alcohol use to see if there is a difference in effect of oxytocin versus placebo between groups.
We conducted an observation sub-study of the prospective randomized controlled trial "High Dose Inhaled Nitric Oxide in Acute Hypoxemic Respiratory Failure", in which we analysed the echocardiographic data collected both at baseline when patients where included and 3-5 days later for followup.
Researchers are looking for a better way to treat people who have chronic heart failure with reduced ejection fraction. Chronic heart failure with reduced ejection fraction (HFrEF) is a long-term condition that occurs when the heart is too weak to pump enough blood to the rest of the body. This results in a reduced supply of the oxygen that the body requires to function properly. The common symptoms of HFrEF include breathlessness, weakness, fatigue, and swelling in the ankles and legs. If left untreated, heart failure can lead to other serious health problems, including damage to other organs, which may result in hospital stays or even death. Vericiguat is an approved drug for use in people with chronic HFrEF. It works by activating a protein called soluble guanylate cyclase, which helps dilating the blood vessels and in turn improves heart function. Currently, treatment with vericiguat starts at a daily dose of 2.5 milligrams (mg), which increases to 5 mg after 2 weeks. The dose is then increased to the target dose of 10 mg after another 2 weeks. In this study, researchers are trying to learn how well participants can tolerate and how safe it is to start vericiguat at a dose of 5 mg. Starting directly at the 5 mg dose is expected to help reach the target dose of 10 mg faster. Participants will take vericiguat 5 mg as a tablet by mouth once daily along with their regular heart medications. At the start of the study, study doctors will check participants' medical history and perform full health check-ups to confirm if they can take part in the study. Throughout the study, study doctors will monitor participants' previous and current medications, their heart health, and their overall well-being. This will help researchers assess how safe the study drug is and if they experience adverse events. An adverse event is any medical problem that a participant has during a study. Doctors keep track of all adverse events, irrespective of whether they think they are related to the study treatment. Access to study treatment after the end of this study is not planned. Everyone, including study doctors and participants, will know what drug the participants receive during the study. Participants may be in the study for about 4 weeks. Participants may not benefit from the treatment as the study is designed to assess safety and tolerability: the duration of the study is very short and participants will be taking a low dose of vericiguat without moving to the target dose of 10 mg during the study. However, the findings of this study may enable people with chronic HFrEF to safely skip one initial dosing step and reach the target dose of vericiguat faster. Participants may experience medical problems such as low blood pressure, upset stomach, nausea, dizziness, and headache. Researchers will monitor and manage all these, and other, medical problems participants may have during the study.
Although breast reconstruction is an integral part of breast cancer treatment, there is little high-quality evidence to indicate which method is the most effective. The objective of this study is to compare implant-based and autologous breast reconstruction, in non-radiated patients. The primary outcome is patient reported breast-specific quality of life/satisfaction and the secondary outcomes are complications, factors affecting satisfaction, and cost-effectiveness. Moreover, the study aims to improve the evidence for trial decision-making in breast reconstruction. Randomized controlled trials (RCT) are generally thought to provide the most solid scientific evidence, but there are significant barriers to conducting RCTs in breast reconstruction, making both recruitment and achieving unbiased and generalisable results a challenge. The study design partially randomised patient preference trial (RPPT) might be a way to overcome these challenges. In the present study, patients who consent to randomisation will be randomised to implant-based and autologous breast reconstruction, whereas patients with strong preferences will be able to choose method. The study is designed as a superiority trial based on BREAST-Q and 124 participants will be randomised. In the preference cohort patients will be included until 62 participants have selected the least popular alternative. Follow-up will be 60-months. Embedded qualitative studies and within-trial economic evaluation will be performed.
The overarching research project aims to evaluate of an internet-delivered affect-focused psychodynamic treatment (IPDT) for adolescents aged 15-19 with depression. The previous study was a non-inferiority randomized controlled trial (RCT) comparing IPDT with internet-delivered cognitive behavior therapy (ICBT). The results showed that IPDT and ICBT had similar effects. Adolescents in both treatments showed large improvements in both depression and other outcome measures. Online psychological treatment is also known as guided self-help, where the participant reads texts and performs exercises on their own, with the support of an online therapist. The planned study is an RCT to investigate the effect of therapist feedback and customized treatment for adolescents at risk of not being helped by IPDT. The study builds on analyses of predicted treatment trajectories in the project's previous study. Based on these analyses, algorithms have been developed that identify which young people who, after three weeks of treatment, are at risk of not getting a good outcome from the treatment. In the present study, 240 young people aged 15-19 with major depression will begin IPDT. After three weeks of treatment, the course of the treatment is analyzed using the algorithm and the young people who are at risk of not having a good outcome are identified. These adolescents are randomized to either continue unchanged treatment or to receive detailed therapist feedback on the adolescent's treatment prognosis and instructions to adapt the treatment in consultation with the individual adolescent. The IPDT treatment consists of eight modules and treatment duration is ten weeks. The study evaluates the effect of the treatment on depression and other variables such as anxiety symptoms, emotion regulation and self-image. The project's previous studies have shown that IPDT is an effective treatment that can be offered to adolescents with depression. The planned study can show whether the outcome of IPDT can be further improved by paying attention to adolescents with poorer treatment progress and adapting the treatment more to their needs.
This is a randomized double-blinded randomized comparison between injection of platelet rich plasma (PRP) and placebo for thumb basale osteoarthritis.
The goal of this clinical trial is to compare therapist-guided internet delivered prolonged exposure (I-PE) in simple english to a waiting list condition for immigrants in Sweden diagnosed with post-traumatic stress disorder (PTSD). The main objectives are to establish feasibility and preliminary efficacy of I-PE for immigrants with PTSD in a single-blind, parallel-group superiority Randomized Controlled Trial (N=100) comparing I-PE with a waiting-list condition, starting with a nested pilot (N=30) to ensure feasible and acceptable recruitment and treatment strategies. Study participants will be randomly assigned to either eight weeks of I-PE or a waiting-list for the same amount of time on a 1:1 ratio without restriction. Feasibility and acceptability data will be reported including recruitment rate, sample demographics, data attrition, treatment adherence and a detailed dropout analysis. A preliminary investigation of the within-group effect size will also be conducted. Recruitment is designed to be broadly inclusive with minimal exclusion criteria.
International guidelines recommend intravenous thrombolysis (IVT) for high-risk pulmonary embolism (PE). In high-risk PE where IVT is contraindicated or has failed, surgical embolectomy or catheter-directed intervention (CDI) is recommended. CDI is also recommended as an alternative in patients with intermediate-risk PE with haemodynamic deterioration during anticoagulation treatment. Although there is a lack of randomized studies comparing CDI to anticoagulation or systemic thrombolysis in PE, several studies and recent meta-analyses have shown that CDI is an effective treatment that is associated with fewer complications than IVT, especially bleeding.
Central venous catheters are essential when administering treatment for hematological conditions. Many patients have a decreased platelet count which increases the risk for bleeding complications. Baarle et al. recently published a randomized controlled study where withholding prophylactic platelet transfusions before CVC placement in patients with a platelet count of 10,000 to 50,000 per cubic millimeter did not meet the predefined margin for non-inferiority for postprocedural bleeding events (PMID: 37224197). However, bleedings grade 2 (defined as bleeding that requires external compression) were included despite lacking clinical significance. The aim of the present study is to investigate whether lowering the preprocedural platelet transfusion trigger from 50x10^9/L to 10x10^9/L for insertions of central venous catheters remains safe with regards to postprocedural bleeding events of grade 3-4.
