NCT01323634
The purpose of this study is to evaluate the 24-hour spirometry effect (FEV1) of FF/VI 100/25mcg once daily compared with Fluticasone Propionate/Salmeterol 250/50mcg twice daily over a 12-week treatment period in subjects with COPD.
NCT02148510
The hypothesis of the study is that a bibloc-apnea splint has a comparable efficacy on respiratory measures as a monobloc-apnea splint and that the cost of treatment is the same. The goal is primarily to compare the Apnea-Hypopnea Index (AHI) after 6 weeks of treatment and the cost of treatment during one year. This randomized controlled parallel group multicenter study includes 316 subjects referred for the treatment of moderate to severe Obstructive Sleep Apnea (OSA). The subjects visit the clinic at 5 scheduled occasions.
NCT02909465
Ketamine is the cornerstone of procedural sedation in emergency department but ketamine induced agitation has limited its usage by many physicians. As a solution, some propose using midazolam or haloperidol before ketamine injection. In this randomized double blind clinical trial, patients who are eligible for sedation by ketamine are allocated in 3 groups. In first group, the patients will receive 0.05 mg/kg midazolam, in second group 5 mg of haloperidol and in 3rd group a placebo five minutes before receiving the sedative dose of ketamine (1 mg/kg). The patients are assessed for agitation during and after the procedure the clinician's satisfaction with sedation instrument is evaluated after the procedure.
NCT01761006
The purpose of this research study is to determine whether exhaled nitric oxide (FeNO) goes up during an acute exacerbation of Chronic Obstructive Pulmonary Disease (AECOPD) and whether the level of exhaled nitric oxide returns to normal in the weeks after an exacerbation.
NCT03121547
While the analgesic effects of opioids are well known, evidence suggest that there are differences in the adverse dizziness of the different opioid types, which may influence the gait function differently. However, this has not been investigated scientifically under controlled conditions. Normal gait function is characterized by cyclic movements with a high degree of predictability. As such, the amount of kinematic variability can provide important information about a condition or an intervention that may affect the gait function . Three-dimensional gait analysis is a recognized method to assess changes in stride-to-stride variability associated with a medical condition or caused by an intervention. Thus, opioid induced changes in gait variability, and possible differences between opioid types, can be assessed objectively from differences in the variability of movements obtained from a three-dimensional gait analysis. The purpose of this study is to investigate differences in gait variability induced by two different single-dose opioid formulations and an inert placebo in healthy volunteers and knee osteoarthritis patients.
NCT02049073
Noise-induced hearing loss affects an estimated 5% of the worldwide population, with 30-40 million Americans exposed to hazardous sound or noise levels regularly. Sources of noise may be occupational, blast noise, or recreational. Trauma to the inner ear can occur through transient hearing loss or permanent hearing loss. Although hearing recovers after temporary transient hearing loss, growing evidence suggests that repeated temporary transient hearing loss may lead to a permanent hearing loss. Currently, there are no treatments and there are no known medications that can be used clinically to prevent noise-induced hearing loss in humans. The long-term goal of this research is to find medications that can prevent noise-induced hearing loss. The purpose of the present pilot study is to evaluate zonisamide and methylprednisolone as medications to prevent temporary transient hearing loss in humans.

NCT02319655
During the last decade optical coherence tomography (OCT) extended the possibilities for in vivo macula diagnostic and was increasingly used for pre- and post-operative imaging of retinal diseases. Spectral-domain optical coherence tomography (SD-OCT) with its increased scanning speed and image-resolution provides more detailed information of microstructures in the macula. Epiretinal membrane (ERM) is a disorder involving the posterior pole of the eyeball. It can be idiopathic or caused secondarily in various ocular conditions, such as uveitis, trauma, retinal detachment or retinal vascular diseases. In patients who suffer from loss of vision and metamorphopsia, vitrectomy and membrane peeling is usually performed to remove the ERM. Different study groups showed that intraoperative use of SD-OCT is possible. Two groups already achieved to work operation microscope integrated SD-OCT setup. Due to the high axial resolution of the SD-OCT some groups reported about an increased hyporeflective zone in the subfoveal region appearing directly after the membrane peeling procedure. It was hypothesized that this phenomenon could be an expression of surgical trauma, as this hyporeflective zone disappears in follow up OCT 10 days after surgery.
NCT02401711
The purpose of this study is to compare the effectiveness of two methods, safety curriculum in addition to online training alone, for teaching patient safety to surgery residents. Despite multiple studies evaluating educational safety curricula, the best methods for teaching residents about patient safety is unknown. It is hypothesized that empowering surgery residents to actively engage in behaviors to increase patient safety may lead to a higher quality perioperative care and communication.
NCT02079090
Sedation and pain medication is required when bone fractures need to be fixed in the emergency department (ED). Many drugs have been used safely as single agents or in combination for the sedation of children. These drugs include Propofol, Ketamine and Fentanyl. However each of these medications has side effects and drawbacks. The combination of Propofol and Fentanyl (Fentofol) has never been compared directly with the combination of Propofol and Ketamine (Ketofol) for painful procedures in the ED, and the goal of this study is to determine which combination works better. The primary outcome of this study is to determine which drug combination has a shorter time from onset of sedation to full recovery. The investigators hypothesize that Fentofol will have shorter sedation to recovery times.
NCT02383953
This study aims to investigate the role of non-genetic factors in the pathogenesis of inflammatory bowel disease.An exploratory study to investigate differences between the epigenome, microbiota and functional immunology in twins discordant for inflammatory bowel disease.
NCT02768012
Antidepressant-induced sexual dysfunction (AISD) affects the majority of women taking antidepressants and reduces medication compliance: however there is a paucity of evidence-based strategies for the management of this condition. Mindfulness-based cognitive therapy (MBCT) has been shown to be effective in the treatment of non-antidepressant-induced sexual dysfunction and may be beneficial in the treatment of AISD. The investigators propose a randomized, controlled, proof-of-principle trial to establish preliminary evidence of efficacy of MBCT in AISD and to inform the design of a larger trial to evaluate its effectiveness
NCT02853916
The objectives of this trial are to confirm efficacy in human of a brown seaweed powder and explore dose-response relationship by comparing two different doses. The primary endpoint is incremental area under the curve (iAUC, mmol\*min/L) for blood glucose.
NCT03320187
This study aims to establish the efficacy of transdermal glyceryl trinitrate as a nitric oxide donor in addition to dinoprostone for induction of cervical ripening in the third trimester through progression in the Bishop's score during 24 hour period.
NCT02532426
In addition to chronic airflow obstruction, patients with Chronic Obstructive Pulmonary Disease (COPD) suffer from skeletal muscle dysfunction which is a prominent and disabling feature and also an independent determinant of survival. Muscular impairment involves loss of muscle oxidative phenotype (OXPHEN: a slow-to-fast shift in fibre types and reduced oxidative capacity). Since hypoxia obviously is a key feature of COPD, the aim of this study is to elucidate the role of hypoxia in loss of muscle OXPHEN. Thus, OXPHEN and expression levels of its key regulators will be determined in the baseline biopsies for association with the degree of hypoxemia. In addition, expression levels of the key OXPHEN regulators will be measured in pre/post exercise biopsies.
NCT03313869
This experiment consists on a 20-day reduction in daily step in free-living active individuals to induce physical inactivity. This will be used to test the efficacy of the anti-oxidant cocktail we aim to test as a new countermeasure in 2016 during the 60-d bed rest planed by ESA/CNES. The objective of this study is to investigate whether the cocktail of natural antioxidants XXS-2A comprising vitamin E and coupled with omega-3 helps to prevent and / or reduce the glucose intolerance and improve oxidative defenses induced by 20 days of physical inactivity through daily step reduction Although physical inactivity is reported to affect glucose tolerance within days of inactivity, we selected a period of 20 days for the effect of the cocktail to take place and assess secondary molecular mechanisms. The effect of this short period of inactivity on metabolism will moreover be boosted during the last 10 days by taking fructose, a sugar found in abundance in fruits, honey and juices, which is known to quickly trigger metabolic deregulation.

NCT01765725
The aim of the study is to develop, carry out, evaluate and measure the effects of a new patient education program for patients with Chronic Fatigue Syndrome (CFS)in primary healthcare. In an randomized controlled trial design the effects of the patient education program on coping, physical functioning, fatigue, pain, acceptance, anxiety, depression, quality of life, self- efficacy, and illness perception will be compared with treatment as usual. The results of the main project will lead to the elaboration of the final patient education program that can be implemented in primary health care, as well as development of a training program for future program-conductors.
