There are about 11304 clinical studies being (or have been) conducted in Denmark. 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 STRATIFY II trial investigates the efficacy of three different approaches to reducing thrombus burdon in patients with acute intermediate high-risk pulmonary embolism: percutaneous embolectomy (the Flow Triever® system, INARI medical), USAT (EKOS® system, Boston Scientific with low dose alteplase) and heparin with the option to perform full-dose thrombolysis. As a co-primary secondary end point the trial assess the incremental efficacy of the embolectomy vs the catheter based low dose thrombolysis approach. Thus the two main hypothesis being tested are: 1. Thrombus burden reduction after 48-96 h is increased with a catheter based (embolectomy or USAT) compared to the a heparin with optional high dose thrombolysis approach (1st co-primary outcome) 2. Thrombus burden reduction after 48-96 h is increased with percutaneous embolectomy compared to USAT with low-dose alteplase (2nd co-primary outcome)
The optimal treatment of complex shoulder fracture is controversial. In general, non-surgical treatment is recommended for older patients, but results are often unsatisfying. Therefore different surgical approaches have been tried to improve outcomes for this group of patients. Reverse shoulder arthroplasty has shown promising results for these types of fractures and changes in the design of the implant might improve outcomes further. The aim of this study is to compare the outcomes of complex shoulder fractures after non-surgical versus surgical treatment and compare two different types of implants.
Mental health problems are rising among children and adolescents. This may not only impact the child's level of daily functioning but also close family members. Informal caregiving is defined as unpaid care for a sick, disabled, or other closely related person. Providing long-term informal care has been associated with detrimental stress-related outcomes, and being simultaneously active in the labor market has been highlighted as an increased burden for the caregiver. Workplaces are poorly suited for dealing with private stressors despite their potential negative consequences for the caregiver's job status and health. There is a need for improving understanding of how long-term informal caregiving impacts job and health outcomes, as well as for measures minimizing potential negative consequences among at-risk occupational groups.
The study investigates the short- and long-term impact of a major organizational change on employee health and productivity. Changes in organizations is a common aspect of modern work life in all sectors and public healthcare is no exception. However, emerging evidence suggests that organizational changes may be a potential stressor which can impact on employee well-being and contribute to stress-related health problems. Using a large-scale natural experiment, the overall aim of the study is to investigate the impact of a major organizational change that took place during 2016-19 on employee health and productivity. In addition, we aim to identify groups that may be at increased risk of experiencing negative consequences of the reorganization. These at-risk groups can in turn be candidates for extended preventive measures when planning future major organizational changes.
The study aims to explore if non-response bias exists among individuals with chronic back pain, focusing on the impact of chronic disease count, treatment burden from multimorbidity, and health-related quality of life. Data is gathered from patients at Aalborg University Hospital's Rheumatology Department via electronic means and medical records. The analysis comprises two-wave assessments, investigating disparities among patients responding to study invitations based on response patterns: first, second, or third invitation responses. Utilizing baseline data, a one-way ANOVA is employed to detect potential between-group variations in the mentioned factors. Subsequently, a repeated measures ANOVA is conducted to evaluate differences among groups over time. Additionally, statistical analyses are conducted to scrutinize variances in age and gender distribution between respondents and non-respondents to the questionnaire invitations at baseline.
Improving oxygenation and ventilation in drowning patients early in the field is critical and may be lifesaving. This may be achieved by helicopter emergency medical services (HEMS) such as the Danish Air Ambulance, or the Royal Danish Air Force's Search And Rescue (SAR) helicopters. The SAR operates in all weather conditions and is equipped with a hoist system, able to hoist patients from the sea or small ships without helipads. This study aimed to estimate the incidence of drowning missions attended by the Royal Danish Air Force's SAR helicopter and describe patient characteristics and prehospital interventions.
The Danish Drowning Formula (DDF) was designed to search the unstructured text fields in the Danish nationwide Prehospital Electronic Medical Record on unrestricted terms with comprehensive search criteria to identify all potential water-related incidents and achieve a high sensitivity. This was important as drowning is a rare occurrence, but it resulted in a low Positive Predictive Value for detecting drowning incidents specifically. This study aims to augment the positive predictive value of the DDF and reduce the temporal demands associated with manual validation.
Fabry is a rare X-linked metabolic lysosomal disorder caused by deficiency in the enzyme α-galactosidase A (alpha-Gal A) by mutations in the GLA gene, encoding the alpha-Gal A enzyme, which catalyses glycosphingolipids, namely globotriaosylceramide (Gb3). Reduced or absent alpha-Gal A activity leads to accumulation of Gb3 in various organs as well as cellular dysfunction and inflammation causing phsyical symptoms and eventual organ failure. Treatment has been available since 2001 for Fabry patients - first enzyme replacement therapy and since 2016, an oral chaperone therapy, Migalastat. Although the initial trials of Migalastat had some both short and extended outcome treatment comparisons, the overall evidence of clinical efficacy is based on too small numbers considering the heterogeneity of the Fabry patient population as well as the very slow progression of the disease. Though the body of real-world evidence is growing, there is a need for more publications of real-world long-term data on clinical outcomes with a focus on treatment with Migalastat. Research Question: Is the incidence and prevalence of Fabry associated clinical events (FACEs) (cardiac, renal, and cerebrovascular) associated with sex, genotype, phenotype at time of diagnosis, biomarkers, and Fabry specific therapy? Objectives: - To investigate time to first Fabry associated clinical events (FACE) (cardiac, renal, and cerebrovascular) with particular focus on Migalastat clinical outcomes and treatment outcomes preceding Migalastat therapy. - To investigate the incidence and prevalence of FACEs with respect to Fabry specific treatment, Migalastat, ERT or no treatment. - To describe FACEs in accordance with different geno- and phenotypic groups. - To investigate the incidence and time to a first fatal or non-fatal cardiac, renal, and cerebrovascular clinical event, separated by each category. Primary outcomes - Time to first FACE (cardiac, renal, and cerebrovascular) with particular focus on Migalastat on clinical outcomes and treatment outcomes preceding Migalastat therapy. Secondary outcomes - To investigate the incidence and prevalence of FACEs with respect to Fabry specific treatment, Migalastat, ERT or no treatment. - To describe FACEs in accordance with different geno- and phenotypic groups To investigate the incidence and time to a first fatal or non-fatal cardiac, renal and cerebrovascular clinical event, separated by each category. Exploratory outcomes - To describe disease progression with focus on organ involvement. The study design is a retrospective clinical and paraclinical follow-up of the Danish National Fabry cohort in the period 01.01.2001-31.12.2022. Patient followed a structured yearly monitoring program as part of routine clincal care.
Acute brain injury due to aneurysmal subarachnoid haemorrhage (SAH) or traumatic brain injury (TBI) is a condition with a high mortality, and surviving patients often have permanent disabilities. Multimodal neuromonitoring of intracranial pressure, brain tissue oxygen tension (PbtO2), and brain energy metabolism (measured with microdialysis (MD)) may help individualise the treatment of this patient group to protect the brain and potentially improve outcomes. However, there is still a significant lack of knowledge regarding the advantages and disadvantages of this type of monitoring. The present study consists of four substudies with the overall aim of examining which factors are most influential for regulating commonly measured intracerebral parameters such as oxygenation, glucose, and lactate. Additionally, the influence of these of parameters on functional outcome and mortality will be explored. The individual studies are detailed below:
Atrial fibrillation (AF) is the most common heart rhythm disorder affecting 2-4% of the adult human population. AF is a disturbance in the electrical impulses of the heart - an electrical disturbance commonly originating from the pulmonary veins. Normalization of the heart rhythm with anti-arrhythmic drugs often fail and is frequently associated with side effects. Therefore, a treatment termed ablation by catheters via an inguinal vein has been devised and is increasingly being used for the treatment of AF. The cornerstone of this treatment is electrical isolation of the pulmonary veins so that the nocuous electrical impulses from the pulmonary veins cannot cause a disturbance in the heart rhythm and initiate episodes of AF. This treatment is called pulmonary vein isolation (PVI). Recent studies have shown that PVI is better than anti-arrhythmic drug treatment in the prevention of recurrence of AF, but despite substantial improvements in techniques and tools only 60-70% are cured from AF by a single PVI procedure, and in around 80% of patients who require additional catheter ablation, durable isolation of all the pulmonary veins has not been achieved. Improved tools for durable PVI are therefore required. A novel catheter to achieve PVI called the HELIOSTARâ„¢ radiofrequency balloon ablation catheter has shown promising clinical results with a favorable safety profile, but the durability of PVI has not been evaluated. Therefore, we aim to investigate the long-term durability of PVI by the radiofrequency balloon and the clinical outcome following the procedure. In this study, patients with AF referred for catheter ablation will undergo an initial PVI treatment using the radiofrequency balloon catheter. All patients will undergo a repeat electrophysiology (EP) study after 4-6 months to determine to durability of PVI. Patients will be issued with a 48-hour heart rhythm monitor at 3 and 12 months after the initial PVI. Patients-reported effects on quality of life by AF related symptoms will be evaluated using a specialized questionnaire provided approximately every third month throughout the 12 month follow-up.
