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 aim of this randomized controlled trial is to investigate the effects of a Swedish Internet-based treatment program for individuals from the general population with a regular cannabis use. The primary hypothesis to be tested is that the use of the Internet-based treatment program will be associated with more cannabis-free days in comparison to only access to information about cannabis use and its harmful effects. The secondary hypotheses to be tested are: 1. That the use of the Internet-based treatment program will be associated with a larger decline in cannabis consumption (frequency and quantity) among individuals with regular cannabis use in comparison to only access to information about Cannabis use and its harmful effects. 2. That the use of the Internet-based treatment program will be associated with a larger decline in alcohol consumption, depression and anxiety and increased sense of coherence in comparison to only access to information about Cannabis use and its harmful effects. 3. That the proportion of individuals who seek professional help or talk to their relatives or friends about reducing or stopping cannabis use will be greater among those who use the Internet-based treatment program than among those who only have access to information about cannabis use and its harmful effects. Recruitment procedure and baseline measures Study participants will be recruited through an advertisement on Cannabishjalpen.se. Interested individuals will answer questions about gender, age, country of birth, educational attainment, employment, marital status, living situation, and cannabis use. The intervention group Individuals randomized to the intervention group will directly after randomization answer questions about alcohol use, use of drugs other than alcohol and cannabis, depression, anxiety, a sense of context and whether they during the last 12 months has received professional help to reduce or quit their cannabis use or during the same period have raised this issue with their relatives or friends. Further, they will fill out a survey on Internet-based services for individuals who wish to reduce or quit their cannabis use. The study participants will then be informed that they, within two days, will gain access to an internet based treatment program designed to help them quit their cannabis use and that they through the program will have the opportunity to communicate with a therapist. Within the next two days, they will gain access to the internet-based treatment program, they will have access to it for two months and they will be contacted again after three months to answer questions about their cannabis and alcohol use, as well as about other previously mentioned issues. The control group Individuals randomized to the control group will undergo exactly the same procedure as the intervention group. The difference is that the control group will be informed that they in about three months will gain access to an internet based treatment program designed to help them quit their cannabis use (i.e. when the data collection for follow-up is completed). Otherwise, participants in both groups will have the opportunity to use factual information that is available to everyone on Cannabishjalpen.se. Follow-up procedure Study participants who were randomized to the intervention group will have access to intervention in two months. Three months after recruitment to the study, study participants from both groups will get an automated email invitation to participate in the three-month follow-up. The email will include a personalized link that when clicked on will redirect the participant to follow-up page where they will be asked to once again answer questions about their cannabis and alcohol use, depression and anxiety, seeking professional help for cannabis use as well as the help of family or friends and questions about whether they have used any other internet or telephone services to reduce or quit their cannabis use. The entire follow-up procedure will be completed via the internet.
The investigators want to compare the effects of two drugs, levosimendan and milrinone, on cardiac muscle, both in terms of contractility and relaxation. Half of the participants will be randomized to each drug. The effects will be measured through echocardiographic deformation analyses. Since deformation analyses could be dependent on different loading conditions of the heart, a second purpose of the study is to investigate the changes on deformation parameters after applied changes in preload and afterload, but also heart rate.
The purpose of this randomized trial was to compare reconstructive surgery of advanced peri-implant intra-osseous defects with porous titanium granules (PTG/Test) to open flap debridement (OFD/Control) in a non-submerged technique over 6 months.
Acute kidney injury is a common complication after cardiac surgery with cardiopulmonary bypass (CPB). This study aims to investigate the effects of CPB on renal perfusion, filtration and oxygenation.
The purpose of this study was to demonstrate efficacy including effect on inhibition of progression of structural damage, safety and tolerability up to 2 years with primary focus at Week 16 (week 24 for structural damage), to support the use of secukinumab pre-filled syringe (PFS) by subcutaneous (s.c.) self-administration with or without loading regimen in subjects with active Psoriatic Arthritis (PsA) despite current or previous NSAID, DMARD therapy and/or previous anti-TNFα therapy. Long term efficacy up to 2 years was based on signs and symptoms of joint/bone structure preservation (X-ray) and improvement in physical function measured by Health Assessment Questionnaire - Disability Index (HAQ-DI©), as well as skin and nail improvement for psoriasis signs.
The purpose of the study is to study how a person-centered structured team caretaking of young adults (16-23 years) with newly diagnosed rheumatoid arthritis (RA), spondartrit (SpA) and psoriasartrit (PsA) in routine clinical care affect and predict the patient's health and ability to manage their everyday lives. Also included in the project is a long-term follow-up (up to 50 years) where the investigators want to investigate factors predicting good general health, low disease activity, good physical function, and comorbidity.
Out-of-hospital cardiac arrest (OHCA) is one of the leading causes of mortality in the industrialized world. Bystander CPR before arrival of the Emergency Medical Service (EMS) is a positive predictor of survival. During the last decade, the best form of bystander CPR has been debated. Chest Compression Only CPR (CO-CPR) has been advocated as a preferable method in situations where the bystander has no previous knowledge in CPR, both because its believed to be equally efficient but also a simplified form of CPR that could lead to a higher incidence of bystander-CPR. The purpose of this study is to perform av run-in period with focus on safety and feasibility prior to the launch of a larger randomized trial which has a primary end-point of survival. This study will compare OHCA with standard CPR (S-CPR; chest compressions and rescue breaths in a 30:2 fashion) compared to CO-CPR.
The purpose of this study is to determine whether reduced rectal blood flow is associated with the extent of surgery when performing an operation to remove rectal cancer. The investigators also aim to describe any relation of reduced rectal blood flow, as well as raised inflammatory biomarkers in blood and tissue, to the occurrence of anastomotic leakage. The patients will be recruited at Umeå University Hospital and all patients who are planned to undergo anterior resection for rectal cancer and able to consent are eligible for this study. Rectal blood flow measurements will be conducted with Laser-Doppler technology using noninvasive measuring probes. Preoperative and postoperative blood sampling as well as postoperative drain fluid collection will take place. Perianastomotic tissue will also be collected. In the postoperative period, any occurrence of surgical complications especially anastomotic leakage, will be noted. Blood flow and biomarkers will be assessed in relation to type of mesorectal excision (total or partial) and correlated to anastomotic leakage. Standard statistical tools will be utilized, such as parametric, non-parametric tests and logistic regression, as appropriate. The study will recruit approximately 40 patients during three consecutive years.
Only to a limited extent has been compared the effectiveness of physical exercise and psychological interventions in subjects with chronic pain. Knowledge about this is necessary in order to compose optimal multimodal rehabilitation programs at different health care levels. Moreover, assuming that both types of interventions have effects, these effects may necessarily not concern the same outcome variables. Therefore it may be important to understand to what extent the effects overlap and the extent to which the effects are isolated to an intervention. The overall strategic purpose of the present study is to develop effective multimodal rehabilitation programs. In this study the effectiveness of following three interventions are compared. - Group-based rehabilitation according to a concept based on an Acceptance and Commitment Training -Stress Management Intervention (ACT-SMI) - Group-based rehabilitation compromised of physical exercise (Exercise). - Group-based discussion concerning pain and its consequences (i.e., the control group, CON) The effectiveness is investigated with respect to long-term effects on pain and its consequences, including perceived health and return to work / sick leave. The overall hypothesis is that the former intervention means better long-term results because it clearly helps the individual to process the psychological aspects of itself likely to have long lasting effects.
The purpose of this study is to examine whether person-centered high-intense aerobic / strength training during five months reduces inflammation and disease activity, improve immune cell function, and increases muscle strength, fitness and ability of the individual independence in elderly patients with rheumatoid arthritis.
