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.
Adult patients suspected of Squamous Cell Carcinoma of Unknown Primary (SCCUP) will be prospectively enrolled at a tertiary head & neck cancer center at Copenhagen University Hospital - Rigshospitalet, Copenhagen, Denmark. All patients will undergo Magnetic Resonance Imaging (MRI) and Positron Emission Tomography-Computerized Tomography (PET-CT) prior to examination in general anesthesia. During general anesthesia, Intraoperative Transoral Ultrasound (ITUS) will be performed prior to panendoscopy. Detected tumors will be registered with specified oropharyngeal sub-locations. Blinded to ITUS, a consultant head & neck surgeon will perform panendoscopy. After examination, the surgeon is unblinded to ultrasound results. Final histopathology results from location-specified biopsies performed will be used as reference standard. The overall detection rate will be compared between ITUS, panendoscopy, PET-CT and MRI with sensitivity and specificity analysis. Oropharynx sub-location specific detection rate of ITUS vs. panendoscopy will be compared with logistic regression analysis.
The study is a randomised, single-blinded, controlled crossover study. The total study duration for the individual subject will be between two days - two weeks, consisting of three site visits. Visits 0 and 1 can be performed on the same day. Visit 2 can be performed the day after visit 1. For visit 1 and 2, catheterizations will be performed in a hospital setting by a health care professional for bladder emptying assessment and collection of urine samples for haematuria assessment. A sub-group of subjects (all enrolled subjects at DK sites) will be asked to conduct a self-catheterization at visit 2 after hcp catheterization and evaluate discomfort and PVR. The total study duration for the individual subject will be up to 14 days.
In a randomized study the investigators aim to characterize the effect of antidepressive medicine on quality of life, body composition, adrenal activity and glucose metabolism in PCOS. PCOS is a common endocrine disorder characterized by adrenal and ovarian hyperandrogenaemia, anovulation and insulin resistance. The pathogenesis of PCOS may be described by a vicious cycle involving insulin resistance which stimulates ovarian and adrenal hyper androgenaemia and leads to abdominal obesity, causing increased risk for diabetes and cardiovascular disease. Adrenal hyperactivity is associated with depression. Antidepressive medicine may normalize pituitary-adrenal activity and in animal studies antidepressive medicine improved adrenal hyperactivity and normalized insulin sensitivity.
The objective of this trial is to investigate if short intervals (1-2 days) between training sessions are more efficient than practicing with longer intervals (6-8 days) between sessions during proficiency-based laparoscopic simulator training. Our hypothesis is that just 1-2 days of break between sessions is optimal for the acquisition of laparoscopic skills and that a shorter interval between sessions is optimal for training.
The goal of this randomized study is to investigate the effect of introducing contextual variation on transfer when learning a technical skill in a group of medical students. The main questions it aims to answer is: If context variation of specific affordance conditions enhance the learner's ability to transfer out? Participants will practice performing an invasive ultrasound guided procedure either on a fantom with maximum affordances or with contextual variation. Researchers will compare the maximum affordances group and the contextual variation group to see if its effects compared to the control group with minimal affordances.
In competitive sport, it is illegal to manipulate erythropoiesis. Manipulated erythropoiesis can indirectly be identified by atypical fluctuations in key haematological variables. However, this method also has limitations and as it is known that some athletes still manipulate erythropoiesis it is necessary to develop new and more sensitive detection methods. The primary purpose of the study is to examine the importance of altered erythropoiesis for surface and intracellular erythrocyte proteins, the number of immature reticulocytes, and for the haematological characteristics of the erythrocyte, such as volume, haemoglobin concentration and concentration of glycosylated haemoglobin, to assess whether these can be used to identify changed erythropoiesis. Furthermore, the aim is to examine whether these parameters are affected by freezer storage of erythrocytes.
Stress-related disorders have over the last decade increased and contributed to a worldwide disease burden. At the same time there is limited treatment access for mental health disorders, which has left many people without necessary care. However, in recent years there has been a rise in digital mindfulness interventions. Specifically, these interventions have focused on smartphone-based applications as an effective format for mindfulness training programs. Thus, the goal of this randomized controlled trial is to test the effects of three types of mindfulness programs in a population with elevated stress. The three formats of mindfulness interventions are identical in total training duration but varies in content and intervention length. Specifically, the first intervention consists of programmatic mindfulness content that progress over the course of 30 sessions with a duration of 10 min per session. The second intervention consists of single succinct breathing exercises with no programmatic content over the course of 30 sessions with a duration of 10 min per session. The third intervention consists of mindfulness-based content specifically targeted to people with elevated stress that progress over the course of 20 sessions with a duration of 15 min per session. An active control group listening to an audiobook over the course of 30 sessions with a duration of 10 min per session will be employed and a passive control group. The study will evaluate outcomes related to subjective stress, sleep quality, mindfulness and physiological effects of stress using HRV.
The objective of this study is to evaluate the effect of a person-centered training and nutrition intervention six month after discharge in acutely admitted frail old medical patients on physical function. Secondly, to evaluate the effect on frailty, quality of life, health literacy, nutrition, readmissions, death and consumption of home care costs.
The goal of this observational study is to assess the size and location of cutaneous sensory block area after dual laparoscopic assisted transverse abdominis plane block (L-TAP) with ropivacaine in patients undergoing laparoscopic cholecystectomy. L-TAP is applied as a medial subcostal infiltration between midclavicular and central sternal lines and a lateral subcostal infiltration between midclavicular and anterior axillary line bilaterally.
Patients planned for elective laparoscopic cholecystectomy received a peroperative ultrasound-guided subcostal transversus abdominis plane block (USTAP) at the beginning of the procedure. At T90 minutes after the end of anaesthesia the cutaneous sensory block area (CSBA) was measured using cold sensation and mapped with a sterile marker. The CSBA was photodocumented and the area calculated.
