Filter by:The purpose of this research study is to 1) understand how some, but not all people with obesity develop obesity related conditions such as type 2 diabetes and cardiovascular disease, and 2) compare the effects of 3 popular weight loss diets (Mediterranean, low-carbohydrate, or a very-low-fat plant-based diet) in people with obesity.
This study uses a special type of scan called a positron emission tomography (PET) scan to take pictures of the brain. During the PET scan, a special dye called 11C-PBR28 is injected into the body. 11C-PBR28 sticks to parts of the brain where there is inflammation. The purpose of this study is to see if 11C-PBR28 can detect inflammation in patients with Parkinson's disease dementia or dementia with Lewy bodies. 11C-PBR28 is considered a drug by the Food and Drug Administration. 11C-PBR28 is not a treatment for any disease. Rather, 11C-PBR28 can be used to measure inflammation in the brain.
To evaluate the impact of obesity surgery on chronic inflammation.
Studies have shown that certain compounds inside vegetables can reduce the risk of cancer. Carrots in particular have an association with reduced incidence of colorectal, bladder and breast cancer. Compounds in carrots, called polyacetylenes, have been studied in isolated cells that have shown a reduction in cancer cells as well as inflammatory markers which have been associated with an increased risk of cancer. These polyacetylenes have not been well studied in the human body and it is unclear whether they are able to affect the biomarkers of health (disease) including DNA damage and inflammatory markers. The aim of this research project is to determine whether eating a portion of white carrots every day for 6 weeks can lead to a reduction in DNA damage and inflammatory markers compared to a control period of 6 weeks consuming a polyacetylene-free diet and a control food of a high fibre oat biscuit.
Sepsis is still a challenge for clinicians since the detailed pathomechanism are still unknown and until now early markers for sepsis are not defined yet. Immunological pathways and new mediators defined in animal models are not yet investigated in patients with sepsis. Therefore the investigators will measure new mediators in patients with septic shock.
Amniotic fluid (AF) pH can be affected by the maternal and/or fetal conditions such as PPROM, prematurity or fetal distress. It is known that fetal urine is the major content of AF since 20th gestational week. Besides fetal alveolar fluid (FAF), gastrointestinal tract, umbilical cord and fetal side of placenta are important sources for AF. Bombesin-like peptides, 8-hydroxydeoxyguanosine in fetal urine and leukotriene E(4), lecithin, sphingomyelin, lamellar body in FAF are molecules acting on fetal lung maturation. Varying levels of these molecules relevant to the stage of lung maturation may constitute an association to AF pHTo detect the possible effect of AF pH on neonatal respiratory morbidities 1 milliliters of AF is aspirated during C-section before incision of membranes. pH value of AFs were analyzed by the blood gas machine (Siemens RAPIDLab®1200 Systems) of NICU. Maternal and neonatal demographic features and clinical outcomes, incidences of morbidities such as respiratory distress syndrome (RDS), transient tachypnea of the newborn (TTN) are all recorded.
Human immunodeficiency virus (HIV) infection damages body defence mainly by affecting two important white blood cells called cluster of differentiation (CD4) T cells and monocytes. This immune dysfunction leads to persistent inflammation, which is partially resolved with long-term anti-HIV therapy. Importantly, such inflammation increases risk for cardiovascular, diabetes, and kidney diseases. The causes of this inflammation are largely unknown and include HIV itself, presence of other infections, lifestyle characteristics like increased cholesterol levels, obesity, smoking and alcohol abuse. In addition, inflammation can be driven by certain type of anti-HIV therapy called protease inhibitor (PI). PI has been associated with an increase of cholesterol and may contribute to inflammation. A new class of medication that is now available in Canada called integrase inhibitor (II) may have a lesser or no effect on cholesterol levels. Therefore, it is important to study the effect of II on cholesterol levels and inflammation. The purpose of this study is to assess the inflammatory changes, in the blood of persons treated with PI that will switch to the II or may remain on their PI-containing regimen. By comparing persons continuing their current PI-based regimen with those who switch to II-based regimen, we will know if the change from PI to raltegravir (Isentress), a type of II, decreases lipids and inflammatory markers. The adult persons living with HIV, who are on PI-based therapy for more than a year, with any CD4 T cell count and plasma viral load below level of detection, will be invited to participate in the study. 40 study participants will be selected by randomization (like a toss of a coin) to either continue PI-based regimen (20 participants) or switch to raltegravir-based regimen (20 participants) for a period of 12 months. Blood samples of the study participants will be drawn before, during and at the end of study to evaluate changes in markers of inflammation, cholesterol level and CD4 T cell and monocyte function. No experimental anti-HIV medication will be used; change of therapy will include raltegravir which is one of currently recommended medications to treat HIV in Canada. This study will be able to answer this important question whether inflammation can be decreased by switching therapy from PI-based therapy to raltegravir-based therapy. Ultimately, information provided by this study will contribute to the health of persons living with HIV.
This study evaluated the effect of secukinumab compared to placebo on aortic vascular inflammation in adult patients who have moderate to severe plaque psoriasis that is poorly controlled by current psoriasis treatments.
Air pollution is a global environmental and health concern, contributing to onset and deterioration of respiratory and cardiovascular diseases. As climate change and dependence on diminishing fossil fuel supplies have taken center stage in political and scientific debates, renewable carbon-neutral fuels like biodiesel receive increasing attention. The most common biodiesel within the European Union, rapeseed oil methyl ester (RME) is perceived to be a "green fuel", as it is sustainable and of biological origin, and therefore is often predicted to be less harmful to human health. Whilst replacing petrodiesel with biodiesel may have advantageous ecological impacts, consequences to respiratory health remained largely unexplored. The purpose of the current study is to evaluate whether inhalation of 100% RME biodiesel exhaust would result in an acute airway inflammatory response in healthy human subjects, as shown previously following exposure to petrodiesel exhaust.
The health care burden of CKD is substantial and growing with 10-15% of the population affected in both developed and developing countries. It is well established that CKD is associated with systemic inflammation, which promotes cardiovascular disease and body wasting. However, causal therapies to treat systemic inflammation, and treat its adverse consequences remain sparse. As kidney function declines in all forms of CKD, oxalate levels increase in the plasma, leading to increased systemic exposure to oxalate and consequent tissue injury. Work from the investigators has shown that elevated plasma oxalate levels activate the NLRP3 inflammasome which in turn leads to the processing and release of cytokines. The investigators seek to test the hypothesis that oxalate contributes to the systemic inflammation observed in patients with end-stage renal disease (ESRD). The investigators plan to define the association between plasma oxalate levels and signs of systemic inflammation in patients on hemodialysis. In a second step the investigators will examine whether hemodiafiltration lowers plasma oxalate more efficiently than hemodialysis and reduces signs of systemic inflammation. Confirmation of the hypothesis may lead to the identification of oxalate as a novel therapeutic target for interventional trials aimed at reducing plasma oxalate in patients with ESRD.
