Filter by:This study evaluates the effect of extracorporeal removal of inflammatory mediators on the systemic inflammation reaction of patients admitted to the intensive care unit following elective esophagectomy. Half of the participants will be treated with an adsorption device (CytoSorbents Adsorber), while the other half will be treated according to standard care. Significant reductions of interleukin-6 plasma concentration, SOFA score and catecholamine dosage in the intervention group are expected.
Evaluating an innovative molecular imaging technique to visualize inflammation of the atherosclerotic plaque in patients with a recent ischemic stroke (<15 days) with carotid stenosis> 50%, by performing a Positron emission tomography-computed tomography (PET-CT) with PBR06 18F, a tracer for Translocator protein (TPSO).
Modern antiretroviral therapy (ART) has transformed the clinical care and lived experience of HIV infection. However, increased rates of adverse health conditions that are related to immune activation, such as cardiovascular disease (CVD) and neurodegenerative disease in ART-treated individuals persist. An important cause of this inflammation is the gut CD4 T cell loss and the "leaking" or translocation of luminal gut bacteria and other microbes across the bowel wall and into the bloodstream. The use of complementary and alternative therapies is common among people living with HIV, however their efficacy has generally not been well demonstrated. Probiotics are live microbes that may provide a health benefit to the host and the investigators believe that the simultaneous use of probiotics along with antiretroviral therapy (ART) will improve gut CD4 T cell restoration and function and therefore reduce microbial translocation and immune activation. Probiotic Visbiome consists of a high potency blend of eight different probiotics. The precise mechanism of action of Visbiome is unknown, but preclinical studies have shown that Visbiome may modulate the immune response towards a phenotype that is associated with reduce inflammation, and Visbiome was also protective in a non-human primate model of SIV infection. Therefore, we believe that the "beneficial" bacteria from Visbiome will accelerate the normalization of gut immune cells and function in HIV-infected individuals as they start ART. Early resolution of gut immune cells may normalize microbial translocation and immune activation and will reduce the rates of HIV-associated comorbidities.
For the target population of adult patients following primary total hip arthroplasty, the randomized clinical trial will be used to evaluate the efficacy of the use of a mobile negative pressure wound therapy(NPWT) device compared to a standard absorptive dressing in the immediate postoperative period. We will apply two dressing types and evaluate the postoperative wounds with a wound scoring system (ASEPSIS) that incorporates multiple variables of wound infection risk.
This is an adaptive Positron Emission Tomography/ Computed Tomography (PET/CT) and Dynamic Contrast-Enhanced Magnetic Resonance Imaging (DCE-MRI) open-label study design for the investigation of inflammation in adult rheumatoid arthritis (RA) patients, not involving therapeutic intervention. Each study participant will undergo two half body PET/CT scans from the pelvis to the bottom of the feet (including hands and wrists) with an additional bed position centred on the shoulders. One scan will be conducted with 18F-FDG and the other with 18F-GE-180. The first PET/CT scan (PET1) will be performed 4 weeks (28 +/- 2 days) after the first screening visit, whereas the second PET/CT scan (PET2) will be carried out within 2 weeks (7 +/- 7 days) after PET1. The order of PET/CT scans for each subject will be based on a computer generated randomisation schedule after the screening visit. A sub-group of study participants will be invited to undergo an additional dynamic 18F-GE-180 PET scan of a selected joint (knee or wrist) prior to their 18F-GE-180 PET/CT half body scan. The primary objective of the study is to quantify inflammation in joints of RA patients by determining 18F-FDG and 18F-GE-180 uptake using PET, and DCE-MRI parameters.
The purpose of this study is to evaluate if the use of two small doses of intravenous (IV) steroids around the time of knee replacement surgery decrease a patient's pain or use of pain medication. The investigators will also determine if the subjects receiving the steroid will have better pain control and better postoperative outcomes after their surgery.
Investigation on the effect of smoking on thrombus formation in humans. The expression of pro- and anti-thrombotic, anti-oxidative, and inflammatory markers will be assessed in 25-50 year old healthy smokers and non-smokers. The investigators are interested in possible differences between the two groups.
The purpose of this protocol is to obtain biologic materials from the mediastinal lymph nodes from patients with lung disease and mediastinal lymph node involvement in order to: (1) develop a better understanding of the cause and development of lung disorders involving the mediastinal lymph nodes; (2) identify biologic parameters that help diagnose and predict the behavior of human lung diseases; and (3) identify individuals who will be suitable candidates for other protocols such as those involving investigational new drugs.
Intraocular delivery of celecoxib will be an effective means to treat inflammation and macular edema and prevent structural complications and vision loss in patients with chronic inflammation or macular edema who are unable to tolerate corticosteroids due to their side effects.
The primary goal of this preliminary project is to study the effect of etanercept, a medicine approved by Health Canada for the treatment of rheumatoid arthritis, on the inflammation of certain blood vessels. In particular, the inflammation of the aorta and the carotid arteries will be studied. This study's goal is to determine if etanercept (that blocks TNF (tissue necrosis factor) alpha) could have an effect on blood vessel inflammation. As well, the information from this study will be used to determine the number of patients to recruit in a future study. This study will evaluate the effect of etanercept on 10 patients with rheumatoid arthritis at one rheumatology clinic in Montreal. The 10 patients will be recruited at the Montreal Rheumatology Institute (Institut de Rhumatologie de Montréal) and the images of the blood vessels taken at a medical imaging center will be analyzed by the Montreal Heart Institute. To evaluate vascular inflammation subjects will undergo a PET scan (Positron Emission Tomography).
