NCT02337608
* Approximately 60 patients suffering from moderate to severe ulcerative colitis will be evaluated for improvement of disease activity (efficacy) when taking GLPG1205 or matching placebo once daily for 12 weeks in addition to their stable background treatment. * During the course of the study, patients will also be examined for any side effects that may occur (safety and tolerability), and the amount of GLPG1205 present in the blood (Pharmacokinetics) as well as the effects of GLPG1205 on disease- and mechanism of action-related parameters (Pharmacodynamics) in blood, stool and colonic biopsies will be determined.
NCT01337180
Exposure to noxious gases and particles is associated with an increased prevalence of respiratory and cardiovascular diseases. Thus, investigation of possible airway inflammation and/or systemic inflammation in workers exposed to high levels of dust is important. Silicon Carbide (SiC) Processing Inc. provides cutting fluid (slurry) for the production of solar cells and is at present the largest provider of slurry to the solar industry worldwide. In the production process, the recyclable materials (SiC), polyethylene glycol (PEG)) of the used slurry are recovered. The airborne exposure consists mainly of SiC (dust particles) and evaporation from the recycling of PEG. High levels of dust have been measured and, seventeen per cent of the measurements in the processing hall were equal to or higher than the Norwegian occupational exposure limit. Thus, assessment of possible systemic and airway effects of this exposure is of interest. A prospective design will be applied and the effects studied by means of registration of respiratory symptoms, spirometry, nitric oxide (NO) in exhaled air, induced sputum and blood sampling over a 3 year period. Exposed subjects will also be compare with non- or low exposed subjects (administrative/office workers). Efforts will be made to include all eligible subjects and to avoid drop-outs. If early signs of airway or systemic inflammation in workers or in cells are demonstrated in the study, it will be necessary to implement measures to reduce the exposure levels. The primary aim of the present study of workers exposed to Silicon Carbide dust in the workplace is to determine whether this exposure is associated with inflammatory changes in the lungs. The secondary aims are: - to examine possible changes in systemic inflammatory markers and - to examine changes in lung function among Silicon Carbide processing workers during a period of 3 years. Possible changes in lung function will be monitored by spirometry and gas diffusion measurements (study A). Airway inflammatory responses and changes in circulating inflammatory markers will be assessed by examination of the induced sputum samples and blood samples every 6th month in a subgroup of workers (study B).

Other efficacy and safety endpoints will additionally be analyzed.
NCT01170481
Assessment of optic disc morphology can be difficult in patients with uveitis and papilloedema. Therefore different optical coherence tomography (OCT) and laser scanning techniques may help to detect damage to the retinal nerve fibre layer.
NCT01983579
This is a prospective, open label study assessing the 24-hour IOP patterns using TF in patients undergoing anti-VEGF injection for the treatment of neovascular AMD (age related macular degeneration). The study will be proposed to patients with AMD and patients with AMD and concomitant open angle glaucoma (OAG). The study will be conducted in two stages. In both stages, patients will remain ambulatory and will be encouraged to follow a schedule as close to their usual lifestyle as possible, with the exception of particular activities such as caffeine intake, playing wind instruments, yoga and strenuous exercise. A patient diary will be distributed for the capture of patient activities during the TF pattern recording. Upon completion of each session, the CLS (contact lens sensor) will be removed and a final ophthalmic examination will be conducted. In the first stage of the study, 20 patients with neovascular AMD with an IOP in the normal range and no concomitant glaucoma will be recruited. After having signed and dated the patient informed consent form, patients will undergo an initial ophthalmic examination. One eye will be selected for the study. If both eyes are eligible, the study eye will be selected in random manner. All 20 AMD patients will receive two 24-hour recording sessions (S) with the TF CLS, at monthly interval. In the first session (S1) anti-VEGF injection will be carried out according to the study center standard protocol. For the second 24-hour TF recording session (S2), patients will be randomly distributed into three groups. Group A, consisting of 5 patients, will receive anti-VEGF injection with a different anti-VEGF substance as compared to S1. Group B, also consisting of 5 patients, will receive anti-VEGF without sclerotomy occlusion after injection as compared to S1. Finally, group C, including 10 patients, will receive anti-VEGF in a different dose (injection volume) as compared to S1. The randomization ratio between groups A, B and C is 1:1:2. The overall study duration for an eligible patient in the first stage of this study is limited to 5 weeks. If in the first stage of this study an injection protocol is identified that provokes significantly lesser elevation on the TF pattern, the alternative injection protocol will be evaluated against the current standard protocol. For the second stage, 30 patients of whom 15 with neovascular AMD and 15 with neovascular AMD and concomitant OAG will be recruited. After giving informed consent and confirmation of eligibility, all patients will receive two 24-hour TF CLS recording sessions (S3 and S4) at monthly interval, during which anti-VEGF injection according to the standard and alternative protocol will be carried out in random sequence. The overall study duration for a patient in the second stage of the study is limited to 5 weeks. The study has been planned to recruit 20 eligible patients in the first stage within 12 weeks from the date of initiation. The second stage will recruit 30 patients within 16 weeks. Hence the overall study duration from the first patient accrued into the study until last patient out equates to about 33 weeks. Allowing for a database lock within 4 weeks of study completion, a preliminary statistical report on the primary efficacy endpoint is foreseen within 2 weeks thereafter.
NCT01857180
Laparoscopic surgery has become the standard approach to a vast variety of surgical procedures. Due factors such as 2D- to 3D conversion, reduced tactile sensation, amplification of tremor and fulcrum effect of the abdominal wall, surgeons require a different set of skills than in open access surgery. Acknowledging this, several comprehensive curricula have been developed to teach basic skills as well as advanced laparoscopic procedures. Despite a recent emphasis on early exposure of medical students to surgery no designated curricula have been developed to introduce medical students to the technique of laparoscopic surgery. Participation in an introductory curriculum in laparoscopic surgery results in improved cognitive and technical performance compared to self-directed learning. The greater homogeneity and fewer dropouts amongst those in the curriculum group suggest that a structured curriculum is essential in ensuring standardization of clinically relevant training. An introductory curriculum for medical students should be delivered in a structured and standardized fashion prior to clinical exposure in order to maintain motivation and enhance learning.
NCT01371136
Although a significant amount of work has been done to validate simulators as viable systems to teach technical skills outside the operating room, the next necessary step is to integrate simulator training into a comprehensive curriculum. The purpose of this study is to develop and validate a comprehensive ex-vivo curriculum for laparoscopic colorectal surgery. This curriculum will include training on a virtual reality simulator, cognitive training and cadaver lab training. The investigators will assess the effectiveness of the curriculum by conducting a randomized single blinded controlled trial. The investigators will be comparing the technical performance of curricular trained and non-trained residents in the operating room, during a procedure on a patient. The investigators hypothesize that surgical residents who participate in the curriculum will have superior technical proficiency and cognitive knowledge relating to performing laparoscopic colorectal surgery compared to conventionally trained residents.

The investigators expect that multibending endoscope will show more higher successful performance than conventional endoscope.
NCT02502552
Prognostic factors in Inflammatory Bowel Diseases (IBD) are currently mainly based on clinical factors (disease extension, perianal involvement, need for surgery, use of immunomodulators…). All of immunological markers (or serological) of IBD have a diagnostic role in indeterminate colitis (ulcerative colitis vs crohn's disease) but they never have been considered as predictors of IBD course in adults. Among the most used, anti-neutrophil cytoplasm antibodies (ANCA) and Anti-Saccaromyces cerevisiae antibodies (ASCA) allow the distinction between ulcerative colitis (ANCA+/ASCA-) and Crohn's disease (ANCA-/ASCA+), and their combined use has a sensitivity and a specificity of about 85%. However, 10 other antibodies have been identified and recently evaluated individually in IBD and especially in pediatric Crohn's disease: anti-ompC, anti-I2, anti-flagellins, anti-glycan (anti-laminaribioside carbohydrate antibodies (ALCA), anti-mannobioside carbohydrate antibodies (AMCA), anti-chitobioside carbohydrate antibody (ACCA), anti-chitin and anti-laminarin), anti-goblet cells and anti-C.albicans specific mannans antibodies. These complementary tests improve the reliability of the diagnosis. In a previous cross-sectional work on a cohort of 195 IBD patients, the investigator showed a prognostic role of some of anti-glycan Abs and especially a correlation with a pejorative form of the disease both in Crohn's disease than in Ulcerative Colitis (UC) and a prediction of corticodependency in IBD.
NCT01551290
The purpose of this study is to evaluate the effectiveness and safety of infliximab in Chinese patients with active ulcerative colitis (swelling and ulceration of large intestine and rectum).
NCT01893476
Background: Chronic Obstructive Pulmonary Disease (COPD) remains a major health problem, which is strongly related to smoking. Despite publication of guidelines on the prevention and treatment of COPD, not all COPD patients receive the best available healthcare. Investigators developed a tailored implementation strategy for improving primary care physicians' adherence to COPD management guidelines. The primary aim of the presented trial is to evaluate the effects of this strategy on physician's performance. The secondary aim is to examine the validity of the tailoring of implementation interventions. Primary Trial Hypothesis: To study if the rate of adherence to the COPD guideline over a 1 year will increase among participants assigned to the intervention group in comparison to those assigned to the control group? Methods/Design: A two-arm pragmatic cluster randomized trial is planned. A total of 540 patients with diagnosed COPD will be included from 18 general practices in Poland. A tailored implementation program will be offered to general practitioners. Participating physicians in the intervention practices (n=18) will receive training to provide brief anti-smoking counselling. An additional form containing COPD severity scale will be inserted into patient's medical records. The checklist with key information about the disease and its management while consulting a patient with COPD will be provided to practitioners. Investigators will provide practices with training inhaler devices for general practitioners (GPs) to teach patients in correct use of each device and to note this education/training in patient's medical records. The control practices will provide usual care. Discussion: The results of this trial will be directly applicable to primary care in Poland and add to the growing body of evidence on interventions to improve chronic illness care.
