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.
As humans age, there is a gradual loss of skeletal muscle mass and strength, termed sarcopenia. The underlying causes of sarcopenia are yet not fully elucidated but are thought to be multifactorial and include increased levels of systemic pro-inflammatory mediators, a decrease in anabolic hormones and changes in the neuromuscular system. Furthermore, physical inactivity, chronic diseases, immobilisation and hospitalisation are known to play an important part in the development of sarcopenia. The prevalence of sarcopenia ranges from 20-30% (aged >70yrs) within the general community. However, the prevalence of sarcopenia in geriatric patients after an acute hospital admission is substantially higher, estimated at ≈50%. Furthermore, successive events of hospitalisation have been suggested to contribute to the development of sarcopenia, as even short periods (4-5 days) of skeletal muscle disuse are known to induce muscle atrophy. Mean length of hospital stay in geriatric wards due to acute illness or hip-fracture is typically 7 to 11 days during which the level of physical activity is strongly reduced leading to an accelerated loss of muscle mass that many older patients never recover from. Notably, a substantial part of the deterioration in functional capacity could be avoided just by counteracting loss of muscle mass during hospitalization. As such, we need to identify sensitive biological, clinical and functional biomarkers predicting loss of muscle mass and function during hospitalization to identify patients at risk of developing sarcopenia. Additionally, it is crucial to investigate the association of these biomarkers with hospital length of stay, as hospitalisation has been suggested to contribute to the development of sarcopenia while longer hospital stays may increase patient risk of hospital-acquired infections and place an economic burden on society.
The study investigates analgesic effects of expectations and deep brain stimulation on chronic and evoked pain in patients with Parkinson's disease. The study includes patients with Parkinson's disease that are exposed to pain stimuli through injection of hypertonic saline. During pain induction and chronic pain evaluation deep brain stimulation treatment is regulated. Pain stimuli and regulation of deep brain stimulation are accompanied by verbal suggestions as to the analgesic effect of deep brain stimulation or no suggestions. During the test session patients evaluate their chronic and evoked pain and expectations. The study procedure is repeated on two separate test days to investigate pain during deep brain stimulation treatment with or without verbal suggestions. All participants will complete all study conditions with no suggestions and verbal suggestions, respectively.
Breast cancer (BC) is the most common cancer diagnosis among women and the incidence is increasing. Prognosis and treatment are dependent on the expression of estrogen receptors (ER) in the tumor. ER status is determined by immunohistochemistry (IHC) on biopsy tissue. The ER expression can change over time and be heterogeneous. The IHC score on ER expression is subjective and can lead to intra and inter observer variability. A new computer image analysis software that can give the exact percentage of colored tumor cells on sectional tumor cuts has been developed. It is also possible to quantify the ER expression non invasive by using the tracer 16α-18F-flour-17β-estradiol (FES) and in vivo positron emission tomography (PET) scans. FES-PET/CT has a high background activity in the liver which complicates the visualization of liver metastases. Theoretically, a new whole body parametric scan method makes it possible to distinguish background activity from uptake in liver metastases. Malignant tumors often have an increased perfusion, and previous studies have found that tumors with low metabolism relative to blood flow have the longest disease free survival (DFS). To the best of our knowledge, no previous studies have examined the correlation between ER expression and blood flow.
The main purpose of this study is to develop and gather validity evidence for a simulation-based test to ensure learning basic competence in gastroscopy.
To demonstrate that use of the Sentinel® Cerebral Protection System significantly reduces the risk of peri-procedural stroke (≤72 hours) after transcatheter aortic valve replacement (TAVR).
Background Low back pain (LBP) is the largest cause of years lived with disability worldwide and often associated with low quality of life, inability to work and low physical activity levels. In Danish general practice, LBP accounts for nearly 10% of all yearly consultations, making it the number one reason for consulting a general practitioner in Denmark. An increase in care-seeking children and adolescents with LBP in general practice is seen in the pre-teen-age-years. At present, no study has investigated on the natural prognosis of LBP among care-seeking adolescents in general practice. Furthermore, the potential impact of patient and parent-related factors on prognosis remains unknown. The aims of the study are to 1) investigate the natural prognosis of LBP and 2) identify patient and parent-related factors which my influence prognosis. Methods Adolescents aged 8 to 19 years consulting their general practitioner due to LBP will be invited to participate in this prospective cohort study. One parent of each patient will be invited to be a part of the parallel cohort. Online questionnaires will be used to collect data on patient characterises, pain intensity, pain frequency, medication, health-related quality of life, physical activity and illness perception at baseline and at the one-year follow-up. Data on pain intensity and parent-related worries will be collected through biweekly text messages. LBP will be assessed by latent class analysis. Discussion This study will be the first to uncover the natural prognosis of LBP within a young, care-seeking population in general practice and to investigate if factors related to the patient or parents influence prognosis.
A study to establish the efficacy of a new type of mechanical rotational chair in treating BPPV. In addition, comparison of three types of treatment maneuvers using the mechanical rotational chair.
The effect of stretching on range of motion is believed to rely upon an increased tolerance to stretch. This suggests, that pain modulation has significance in regards to the effect of stretching.
The objects of this research are to investigate the ability of the motor learning and test the possible differences between younger and older healthy human, and between non-pain and acute experimental pain and chronic clinical pain conditions.
The purpose of the DAN-VNS study is to investigate the effects of non-invasive vagal nerve stimulation on gastrointestinal symptoms such as nausea, vomiting, bloating, and diarrhea in people with diabetes.
