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.
General anesthesia often reduces blood pressure whereby blood flow to the brain and other vital organs may become insufficient. Thus, medicine is often administered to maintain blood pressure but it is unclear at what level blood pressure should be aimed at during anesthesia. Thirty patients undergoing major abdominal surgery will be included. The study will start one hour after the start of surgery and lasts for approximately half an hour. The purpose of the study is to evaluate whether blood flow to the brain can be increased by maintaining blood pressure at a higher level than that used in clinical practice. In the study, MAP is adjusted to a high, moderate, and low level for a short time. The low level of blood pressure used in the study, corresponds to the level aimed at in clinical practice. The drug noradrenaline will be used to control blood pressure. Blood flow to the brain will be evaluated on the neck using ultrasound.
The former Nickel Directive was introduced in EU in 1994 limiting the release of nickel from items intended for prolonged contact with skin. The nickel regulation entered into full force in 2001 and became a part of REACH (the EU chemicals regulation) in 2009. Since then the prevalence of nickel allergy has declined in some countries, but not in others, following the implementation. Young individuals still become allergic to nickel (2, 3) and a high prevalence of nickel allergy, exceeding 10%, is seen among young women (below 30 years) in the general population. The EU nickel regulation has been changing over time. The present limits of nickel release for metallic items intended for direct and prolonged contact with the skin is <0.5 μg/cm2/week and <0.2 μg/cm2/week for any post assemblies inserted into pierced holes. In 2014, EU defined prolonged contact with the skin as: at least 30 minutes on one or more occasions within two weeks for items with continuous skin contact, or to at least 10 minutes on three or more occasions within two weeks (7). The overall objective is to evaluate how well the EU nickel regulation protects individuals against developing nickel dermatitis. More specifically we will: 1. Study the penetration of nickel in normal and irritated skin after short repeated skin exposure under controlled temperature in nickel sensitized patients and in healthy controls 2. Reveal the potential of short repeated nickel skin exposure on normal and irritated skin to elicit dermatitis, during controlled climate factors in nickel sensitized patients and controls using the time restrictions of the definition of prolonged skin contact in the nickel regulation.
The purpose of this study is to evaluate the efficacy, safety, and tolerability of monthly and quarterly subcutaneous (sc) injections of fremanezumab compared with sc injections of placebo in participants with chronic migraine (CM) or episodic migraine (EM) who have responded inadequately to 2 to 4 classes of prior preventive treatments. Approximately equal numbers of participants from each subgroup (CM and EM) are randomized in blinded-fashion 1:1:1 into one of 3 treatments for the subgroup - 2 active treatments and 1 placebo treatment- consisting of monthly injections for 3 months (up to Week 12). Then all participants continue into an open-label extension of 3 months (up to Week 24) during which everyone is administered sc injections of fremanezumab.
Few studies indicate that sprint performance may be impaired in football players with a previous hamstring strain injury. This exploratory cross-sectional study aim to compare sprint performance between football players with and without a previous hamstring strain injury. The findings may elucidate potential indications of insufficient rehabilitation following a hamstring strain injury. Sprint performance data will be collected using the MySprint Iphone Application. Due to pragmatic reasons and the exploratory nature of this study the aim is to include players on a team level. Based on the prevalence of hamstring strain injuries the expected number of cases to be included are 10-20 football players with a previous hamstring strain injury, and a corresponding 80-90 number of healthy controls. No outcomes will be weighted (flat outcome structure).
The effect of cholecystectomy on postprandial plasma GLP-1 responses (primary endpoint) and glucose metabolism will be evaluated in 30 patients planned to undergo elective laparoscopic cholecystectomy.
Several free fatty acids receptors (FFARs) have been discovered. These have been implicated in metabolic processes and inflammation. Consequently, these receptors have attracted interest as targets for the treatment of metabolic and inflammatory diseases, including obesity and type 2 diabetes. Two of these FFARs (FFA1, FFA4), which is activated by specific free fatty acids (FFAs), is expressed on enteroendocrine cells, pancreatic beta-cells and adipocytes. They have been linked to 1) increased glucagon-like peptide-1 (GLP-1) secretion and hence the incretin-mediated increase in glucose-stimulated insulin secretion (GSIS) and suppression of glucagon secretion, 2) a direct positive effect on GSIS, 3) reduced inflammation and 4) improved insulin sensitivity. These functions and the abundance of fatty acids in food suggest that FFARs can be considered as nutrient sensing regulators of metabolism. Roux-en-Y gastric bypass (RYGB), frequently results in immediate beneficial effects on glucose metabolism and often complete remission of type 2 diabetes. This may in part be explained by increased GLP-1 levels after surgery. It appears that the effect depends on nutrient delivery directly to the lower parts of the small intestine. It is possible that the RYGB effects are partly due to enteroendocrine stimulation of FFA1 and perhaps FFA4 by direct nutrient delivery, i.e. FFA release in the lower intestines. Pinolenic acid from pine nuts has been shown to be a potent dual FFA1/FFA4 agonist. Based on these findings the investigators have planned a number of human intervention studies in order to investigate 1) the optimal oral formulation of pine nut oil 2) whether it is possible to mimic the beneficial effects observed after RYGB, 2) if it is possible to increase GLP-1 secretion by stimulating FFA1/FFA4 on enteroendocrine cells causing improved GSIS and increased satiety and 3) enhancement of GSIS by directly stimulating FFA1 on beta-cells.
The purpose of this trial is to investigate whether a self-managed resistance training protocol is more effective than a predetermined resistance training protocol in improving the Foot Health Status Questionnaire pain domain score in individuals with plantar fasciopathy after a 12-week intervention.
10 young males will be recruited to participate in a randomized double blinded crossover study to investigate the influence of concomitant intake of two different types of carbohydrate with protein hydrolysate on the absorption kinetics of protein-derived amino acids and the impact on myofibrillar protein synthesis. During the trial days the subjects will perform a bout of whole body resistance exercise and ingest a supplement of meat hydrolysate labeled with D5-phenylalanine together with randomized and double blinded type of carbohydrate consisting of either glucose or cluster dextrin. The primary outcome is the time to obtain peak concentration of D5-phenylalanine after intake of meat hydrolysate with either glucose or cluster dextrin. Hypotheses: I) The cluster dextrin will increase the absorption of the amino acids from the meat hydrolysate, and thereby result in a faster rise and a higher peak in plasma amino acid concentration in the postprandial period. II) The meat hydrolysate will increase the protein synthesis rate to a higher extent when combined with cluster dextrin than with glucose.
This study evaluates the possible benefits of a tasteless and sugar free chewing gum as a salivary stimulant for head and neck cancer patients treated with curative intended radiotherapy.
Postoperative right ventricular (RV) dysfunction increases mortality and risk of cardiac failure after cardiac surgery substantially. A comprehensive understanding of this condition is paramount in order to achieve success in treatment and early diagnosis. This study has two main aims. Perioperative aim: To investigate correlations between changes in echocardiographic measurements and hemodynamic changes at baseline and following coronary artery bypass graft (CABG) surgery. Postoperative aim: To evaluate changes in haemodynamics and echocardiographic parameters during separate physiological interventions (increase in preload/afterload, oxygen fraction, pacing modes (AAI/DDD/VVI)).
