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.
Achalasia is a rare motor disorder of the gastroesophageal junction which is associated with an increased pressure of the esophageal sphincter. This leads to impairment to swallow and heartburn. Esophageal myotomy, which is a surgical longitudinal incision of the esophageal muscle layer extending over to the gastroesophageal junction is the treatment of choice for achalasia. In order to prevent reflux of stomach content into the esophagus this has to be combined with an antireflux procedure where the upper part of the stomach (fundus) is wrapped around the esophagus (fundoplication). This procedure can be performed with the wrapped fundus either in front of the esophagus (Dor procedure) or behind (Toupet). The latter introduces an angulation of the esophagus, which possibly may lead to an impairment of swallowing ability and passage of food to the stomach. On the other hand, the Toupet procedure may give a better control of reflux. The primary endpoint of the study is symptoms of impaired swallowing 1 year after treatment. Secondary outcomes include reflux (pH measurements in the esophagus), radiological imaging of swallowing and quality of life.
Despite of the widespread use, and extensive studies, the optimal route of administration of misoprostol before surgical abortion remains to be defined. Following administration of 400 mcg vaginally as per clinical guidelines, the time for optimal priming seems to be 3 hours, but the longer the interval the greater the risk or bleeding and expulsion of the uterine contents before the surgical evacuation. Sublingual administration seems to give adequate plasma concentration and cervical priming faster than oral or vaginal administration. This may allow a shorter waiting time with maintained efficacy, less side effects and logistic advantages.
The purpose of this study is to evaluate the efficacy and safety of long-term treatment with lumacaftor in combination with ivacaftor in people 12 years and older with Cystic Fibrosis.
Hypothesis: Pretreatment with mifeprsitone prior to Mirena placement will induce amenorrhea and reduce bleeding irrregularities during the initial months of Mirena use.
There are numerous reported ways to treat chronic subdural hematomas (CSDH) and practice is still differing considerably between departments. Except for a recent randomized controlled trial (RCT) that found that postoperative subdural drainage was better than no drain, there is no higher level evidence. Another recent RCT did not replicate these findings, but the study was severely underpowered. Aim of this population based study is to compare clinical results (reoperation rates, complications, perioperative death, and survival) between neurosurgical departments treating CSDH with different treatment policies.
This trial is conducted in Africa, Asia, Europe and South America. The aim of the trial is to evaluate efficacy and safety of semaglutide once-weekly versus sitagliptin once-daily as add-on to metformin and/or TZD (thiazolidinedione) in subjects with type 2 diabetes.
This study will examine the effect intravenously administered rigosertib has on the relationship between bone marrow blasts response and overall survival in myelodysplastic syndromes (MDS) patients who have 5-30% bone marrow blasts and who progressed on or after treatment with azacitidine or decitabine.
The purpose of the study is to determine whether remifentanil influence the pharyngeal phase of swallowing using using pressure and impedance recordings. The purpose is also to compare remifentanil to morphine and younger to elderly volunteers.
The primary aim of the present study is to study the effect of a brief automated alcohol intervention in University students, and if there is a difference in effect between automated brief interventions delivered by internet (WEB) or Interactive Voice Response (IVR), and to study if there is difference in effect between single and repeated interventions.
This trial is conducted globally. The aim of the trial is to examine the dose range, escalation and efficacy of oral semaglutide in subjects with type 2 diabetes.
