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.
Bowel symptoms like constipation and abdominal pain are characteristic symptoms of irritable bowel syndrome (IBS). The pathogenesis and pathophysiology are not fully understood but subject to intense research, with emphasis on aberrations in the gut-brain axis, low-grade inflammation and gut barrier dysfunction that results in increased permeability and microbial translocation. Many patients with Parkinson's disease (PD) have reported bowel symptoms similar to that in IBS patients decades prior to the diagnosis of PD. Epidemiological studies show a significantly elevated risk of developing PD in IBS patients, though there is no knowledge on a pathogenic connection between these disorders. Recent studies show increased gut permeability and intestinal presence of pathological alpha-synuclein aggregates, the neuropathological hallmark in PD, indicating the involvement of the gut-brain axis. We aim to compare the presence of colonic alpha-synuclein between IBS, PD patients and healthy controls to relate these findings to intestinal permeability, ultrastructural mucosal changes, immune cell interactions, microbiota composition and brain function. This project could identify IBS groups at risk of developing PD and birth the development of early clinical diagnostic methods.
The purpose of the SexCan - WebEd Nurse study is to evaluate the effect of a five week online university course, "Bring it up - Assessment and support of patients' sexuality in cancer nursing", aimed at cancer nurses, on occupational self-efficacy and attitudes towards addressing sexuality with patients.
An explorative study of the Mantis Photonics hyperspectral camera for retinal imaging and estimation of retinal oxygenation. Primary objective: To evaluate the performance of the hyperspectral camera for non-invasive retinal examination in order to improve the diagnosis of diseases affecting the retina or central nervous system. Secondary objective: To investigate the possibilities of the use of a hyperspectral camera for non-invasive retinal examination.
Micro pulse transscleral laser treatment (MP-TLT) is a relatively new method to reduce the intraocular pressure (IOP) in glaucoma. New recommendations regarding the treatment protocol has recently been developed and was published 2022. The overall objective is to evaluate the efficacy and safety of the proposed treatment method in an independent study. In addition, the outcome of MP-TLT in patients with pseudoexfoliation glaucoma, which is relatively common in the Nordic countries, and primary open angle glaucoma will be studied separately. The IOP change over the course of one year will be monitored, as well as success rate and survival. Further, patient-reported discomfort from the treatment and the occurrence of any adverse events or complications will be studied.
The crossover-effect within resistance- and strength training is more or less confirmed with multiple studies showing similar results. The studies shows an increase in muscle strength within the contralateral extremity being exercised. Regarding muscle length or mobility (flexibility) the crossover-effect have not been studied. For a person to gain an increase in muscle strength mobility training in the form of stretching and flexibility training of our skeletal muscle is a common exercise. However, the evidence are scare and there are only a few studies comparing the effect of prolonged static stretching (> 90 sec) and dynamic flexibility training as to which of these methods has the best length-enhancing effect over time. The purpose of this study is to compare the crossover-effect of eight weeks of oneleg dynamic flexibility training versus oneleg prolonged static stretching versus a nonstretching controlgroup on mobility in the hamstring muscles in adults with reduced mobility of the hamstring muscle. The aim is also to compare the sustained effect of flexibility training between the two groups, eight weeks after completion of the intervention.
The study's aim is to assess the sitting and dynamic postural control of stability of wheelchair users who have compromised postural control and risk of ulcers while using individually adjusted multi-cell air cushions with and without individual cell-locking function and variable depths.
Severe-to-profound hearing loss can have a major impact on patients´ lives leading to social isolation and decreased quality of life. Most commonly the hearing loss is caused by damage to the inner ear or cochlear nerve. Since the vestibular system which is central for our balance is located in the inner ear it can be suspected that patients with severe-to-profound hearing loss also might have an impaired vestibular function. This impairment may lead to a feeling of dizziness or vertigo. This study aims to investigate if patients with severe-to-profound hearing loss also have impaired vestibular function. The vestibular function will be measured with caloric irrigation, video head impulse test and vestibular evoked myogenic potential.
Cerebral palsy (CP) is a movement and posture disorder caused by an injury to the developing brain, with a prevalence in Sweden of about 2/1000 live births. Children with CP have walking difficulties, and decreased muscle mass and muscle function as compared to typically developing (TD) children. The extent of disability in CP depends on the severity and timing of the primary cerebral lesion and can be classified with the gross motor function classification system (GMFCS E&R) that ranges from walking without limitations (I) to being transported in a wheelchair (V). Muscle function commonly deteriorates with age and contracture development is often clinically evident as early as at 4 years of age. In addition to being thinner and weaker, skeletal muscle in children with CP develop poor quality, i.e., increasingly higher amounts of fat and connective tissue at the expense of functional, contractile proteins. How long-term standard treatments for children with spastic CP including, training and orthotics use, with botulinum toxin (BoNT-A) treatment as an adjunct, affects muscle on functional, structural, and microscopic level in CP has not yet been published. Therefore, we will investigate the muscle function as well as functional mobility, structure, and spasticity. We will conduct functional mobility tests. Muscle strength will be measured with a rig-fixed dynamometer, and muscle structure will be measured with magnetic resonance imaging. The spasticity will be instrumentally assessed by the NeuroflexorTM, a machine measuring resistance in a muscle when a pedal is passively moving the participants foot at two different speeds. We will follow participants, for 1 year, with 4 measurements during this period. In order to better treat these children, we need to better understand the complex, interrelated interactions of musculoskeletal properties and function in children with CP. Our hypothesis is that muscle structure and function is affected by standard clinical treatments sessions including routine botulinum toxin treatment. Analyzing the effect of standard care may help planning of more effective clinical treatments in the future.
The goal of this clinical trial is to test if manual external aortic compression can prevent heavy blood loss in cesarean section. The main question[s] it aims to answer are: 1. Is external aortic compression safe? 2. Is external aortic compression effective? Participants will receive preventive external aortic compression or no external aortic compression right after the baby is out at cesarean section. Blood loss will be measured, as well as kidney function, hemoglobin, and hematocrit before and after the operation. Experienced discomfort will be assessed the day after surgery and breastfeeding and signs of depression will be assessed using questionnaires after 2 months. Researchers will compare women with and without external aortic compression to see if there are differences in these outcomes.
Operating high-speed boats is dangerous. The purpose of this study is to establish what levels and what characteristics of impact exposure cause injuries. Impact-induced injuries are sometimes severe and cause permanent disabilities. The slamming-impact exposure causes more injuries per workday than seen in most other peacetime work. 12. It is however NOT known which levels or kinds of impacts are dangerous and which are safe or sustainable. To prevent injuries and to reduce fatigue onboard high-speed boats, this knowledge is crucial. Current standards and regulations lack relevance. They are based on mean values of vibrations, and the stated exposure limit values are impossible to comply with even in normal maritime operations. The purpose of this study is to establish what levels and what characteristics of impact exposure cause injuries. This prospective observation study will measure human impact exposure and correlate this to the occurrence and development of pain, used to indicate the risk of injury.
