Active clinical trials for "Inflammation"

Studies with intestinally asymptomatic patients with spondyloarthritis showed that approximately 1/3 had visible ulcers in the colon by scopic examinations and 2/3 had changes detectable by microscopy. Only those patients who improved in arthritis symptoms showed improvement in colonic changes. In these studies only colon and the terminal ileum was examined. Inflammation of the small intestine was not examined. Newer studies have shown an immunological link between Crohns disease and spondyloarthritis but not ulcerative colitis. The investigators wish to examine the small intestine in these patients before and after treatment, since they expect to find ulcers there linking spondyloarthritis to Crohns disease and healing after treatment.

The present project aims at evaluating the diagnostic potential of high-field MRI (3 Teslas) for joint disease. At this field, given that isotropic image resolution of 400 microns can be obtained, one could expect an early detection of joint abnormalities. The additional aim of this project will be to develop a quantitative analyse of the corresponding high-resolution images.

The aim of this study was to characterize the host-related response of peri-implant soft tissue induced by 3 different materials: titanium, resin and PEEK (polyetheretherketone) on man. The primary endpoint is to asses the histological data available: Histological analyses are carried out with immunohistology (CD68, CD3, CD20, macrophages), non decalcified histology to appreciate the structure of the peri implant soft tissues (Sulcus depth, junctional epithelium, connective tissue adhesion). Moreover: scanning electronic microscope (SEM) of the experimental abutment is performed to juge the cell adhesion on the abutment surface. The secondary endpoint is to assess clinical data, radiological bone remodeling regarding the different material. The hypothesis is that resin abutment lead to more inflammation than PEEK or titanium.

An individual's immune and metabolic status is coupled to consumed carbohydrates. Complex carbohydrates that are not digested by human enzymes may influence host biology by impacting microbiota composition and function, or act in a yet-unknown microbiota-independent manner. Prebiotics offer a promising safe route to influence host health, possibly via the microbiota. However, it remains largely unknown to what extent immune function and metabolism can be modulated by prebiotics.

It is increasingly recognized the NSAIDS (nonsteroidal antiinflammatory drug) might prevent the several cancers. In breast cancer, the role of NSAIDS (nonsteroidal antiinflammatory drug) has been suggested.However, there was no consistent results. surgery is main cause of inflammation for cancer patients. Therefore, we want to know the association between prevention of perioperative inflammation with NSAIDS and breast cancer outcomes.

In this study we plan to image the compartmentalized inflammation in MS using molecular imaging by positron emission tomography (PET) with a very highly resolutive camera. Two tracers will be studied and compared: i) [18F]DPA-714, which bind to the peripheral benzodiazepine receptor (PBR), a target mainly expressed by activated microglial cells. This new ligand for PBR displays several advantages compared to the existing reference compound PK11195 in term of brain entrance, signal to noise ratio, and radiolabelling possibility with [18F] ii) [18F]-fluoro-desoxy-glucose ([18F]FDG), which should reflect glucose metabolism in activated immune cells in the white matter. Progressive MS patients (secondary progressive and primary progressive) will be compared to relapsing-remitting patients and to healthy volunteers. All subjects will pass a complete neurological evaluation and a multimodal MRI to document clinical disability and tissue injury. A clinical and radiological follow up will then be performed for a 2-year period. This study should help to understand the contribution of the intracerebral inflammation on the progression of disability and could provide a surrogate marker for further therapeutic trials in chronic progressive MS.

Substantial evidence shows that diets incorporating antioxidants and B-group vitamins can offer significant protection against infections and cardiovascular disease (CVD) especially in diabetic patients. The proposed study will determine whether improvements in antioxidants and B-group vitamins in diabetic patients who are known to have a high risk of CVD will lead to a clinical benefit

The General Aim of this study is to verify if a short term supplementation can modulate diverse aspects related to the physical regular high intensity activity. To get this general aim and following the criteria established by the EFSA Guides, this general aim will be divided in specific or concrete aims, and will be studied by its specific analytical. First Specific Aim: To study how the supplementation with 200 mg of ubiquinol in a short term (2 weeks) study can influence the physical performance, resitance , muscle function and weakening: maintenance of normal muscle function, maintenance of endurance performance, increase in endurance performance/capacity, reduction in the rated perceived exertion/effort during exercise, increase in physical performance and maintenance of muscle mass and piscological variables that the sportsman suffers before and after the high intensity exercise. Second Specific Aim: To study how the supplementation with 200 mg of ubiquinol in a short term (2 weeks) study can influence the biochemical and haematological parameters in sportsman. Third Specific Aim: To study how the supplementation with 200 mg of ubiquinol in a short term (2 weeks) study can influence the oxidative stress asociated to a high intensity exercise. Fourth Specific Aim: To study how the supplementation with 200 mg of ubiquinol in a short term (2 weeks) study can influence the inflammatory signaling, the activity of diverse pro - and anti-inflammatory citokines associated to high intensity exercise.

The main purpose of this study is to examine if there are differences in postoperative inflammation following percutaneous dilatation tracheostomy versus surgical tracheostomy in intensive care unit patients.

In this study, the investigators aimed to find out whether there are any differences in inflammatory reactions occured subsequent to two different cesarean delivery techniques; modified Misgav-Ladach vs Pfannenstiel-Kerr techniques.
