Filter by:Subclinical inflammation is now indisputably recognized as a key etiological factor in the development of atherosclerosis and subsequent cardiovascular disease. Obesity and related dysmetabolic states including metabolic syndrome (MetS) are highly prevalent causes of subclinical inflammation. Obesity and MetS are both diet and lifestyle-related and there is a growing body of literature suggesting that specific nutrients, such as long chain omega-3 polyunsaturated fatty acids (LCn-3PUFA), may attenuate the pro-inflammatory state associated with these conditions. However, careful review of existing literature on this topic reveals important gaps in knowledge, the purported anti-inflammatory effects of LCn-3PUFA even being questioned by many. Significant confounding attributable to study design, sample size and biomarker selection may be responsible in part for inconsistencies in the literature on LCn-3PUFA and inflammation. We also found that evidence available to date (for and against) is based primarily on secondary analyses, as most of the studies published were not primarily designed to investigate inflammation as a primary outcome. It remains unclear whether the different LCn-3PUFA, primarily docosahexaenoic acid (DHA, 22:6n-3) and eicosapentaenoic acid (EPA, 20:5n-3), have similar effects on pro-inflammatory processes as almost all studies were undertaken using a mix of LCn-3PUFA. Whether efficacy of EPA and DHA is influenced by sex/gender is also unknown. Finally, a better understanding of the systemic and tissue-specific mechanisms underlying the anticipated anti-inflammatory effects of different LCn-3PUFA in MetS would also be of great value. Addressing these gaps has important public health implications, considering that LCn-3PUFA supplements are broadly and indiscriminately recommended for the prevention of cardiovascular disease. The overarching objective of the proposed research is to compare the anti-inflammatory effects of EPA and DHA in men and women with MetS.
The purpose of this study is to evaluate the ocular safety, tolerability and efficacy of topical administration of ISV-303 compared with Durasite Vehicle.
The goal of this study is to investigate acute respiratory distress syndrome (ARDS) and septic lung with positron emission tomography (PET) imaging and to examine the distribution of inflammation, as measured by neutrophil metabolic activity.
Phase 2 of this study involves determining how consumption of cheese compared with a non-dairy cheese substitute influences inflammation over a six hour period.
Cardiovascular disease and depression are some of the most costly illnesses to society, and caring for a loved-one with Alzheimer's disease has been associated with increased risk for both depression and cardiovascular disease. Indeed, depressive symptoms have been linked with elevated plasma concentrations of D-dimer and Interleukin-6 (IL-6), both of which are associated with increased risk for cardiovascular disease (CVD). The present research tests a brief behavioral intervention for reducing both depressive symptoms and CVD biomarkers in Alzheimer caregivers. We hypothesize that caregivers receiving a brief Behavioral Activation (BA) therapy will show greater reductions in depressive symptoms and in CVD biomarkers relative to those randomized to a time-equivalent Information and Support (IS) therapy.
Phacoemulsification is a quick method with less complication for cataract surgery. Due to the use of ultrasonic energy, it produced more post-operative inflammation than other methods. Many routes of steroid had been used to control post-operative inflammation. The investigators here compare the efficacy of single depot steroid subtenon injection (20-mg triamcinolone) with four-time-a-day steroid eye drop (0.1% dexamethasone) in controlling inflammation after uneventful phacoemulsification.
The objectives of this study are: 1) To determine whether patients with acute coronary syndrome, the level of environmental exposure to particulate air pollutants in the week prior to admission, are related to concentrations of inflammatory molecules and oxidative stress. 2) To investigate whether the level of environmental exposure is an independent prognostic factor in terms of overall and cardiovascular mortality, myocardial infarction or unstable angina at 30 days, 6 and 12 months.
Background. Obesity, insulin resistance and type 2 diabetes are closely associated with chronic inflammation characterized by abnormal cytokine production. Some authors have found discordances between glycated hemoglobin (HbA1c) and other measures of glycemic control, suggesting that a "glycation gap", defined as the difference between the HbA1c concentration and that predicted by the fructosamine concentration, could explain the excess interindividual variation in HbA1c. The present study was aimed to examine the association between inflammation, sociodemographic (age, gender) and lifestyle factors (diet, exercise, alcohol, and tobacco consumption), and common diseases. In addition, we also examine levels of blood glucose, HbA1c, fructosamine and "glycation gap" determining the prevalence of "high glycators" in a general adult population and their association with lifestyles and prevalent diseases. Methods. Selection of a random sample of the general adult population from a single municipality (A-Estrada, Pontevedra, Spain), stratified by age. The initial sampling includes 3,500 subjects. Considering approximate 67% participation rate, the final study population would include more than 2,000 individuals. The standard workup includes structured questionnaires, skin prick test, periodontal examination, psychological tests, physical examination and blood determinations to allow for categorization of participants in terms of basic demographics, profession, education level, socioeconomic level, quality of life, physical activity, diet, alcohol consumption and smoking, atopy, obesity, diabetes, metabolic syndrome, hypertension, cardiovascular disease, and liver disease. We determine blood levels of inflammation markers, HBA1c, fructosamine and glucose. We will collect a urine sample for microalbuminuria determination. In addition, blood will be drawn to be stored at the Biobank of our Hospital. One half of participants (~1000 individuals) will undergo continuous glucose monitoring. The design is cross-sectional, followed by a longitudinal study using population registries for the determination of events (mortality). Discussion. This comprehensive study in a general adult population provides an excellent opportunity to determine serum concentrations of inflammation and glycation markers and how they can vary widely with age, sex, common habits, metabolic abnormalities, and chronic diseases. The findings from this study should also help to find out the relationship between glucose profiles and HbA1c and fructosamine concentrations with diet and inflammation markers. Keywords: Inflammation, glycation, glycated hemoglobin, glycation gap, continuous glucose monitoring, obesity, allergy, periodontal diseases, depression, metabolic diseases.
With the recent recommendation from Health Canada to extend exclusive breast-feeding to 6 months of age there has arisen concern about what is the best solid food to introduce at that time. Traditionally solids were introduced in Canada at 4-6 months and usually iron-fortified rice cereal was the first food of choice. New recommendations from Health Canada include meat as a potential first food as well as other iron fortified foods. This has lead to uncertainty of both public health officials and parents about the optimal introduction and choice of solids after exclusive breastfeeding. In addition to meeting iron needs with the first solid food choice, the investigators are concerned about the possible generation of reactive oxygen species (ROS) in the gut of the infant fed traditional iron fortified cereals. Infant cereals are fortified at 25-30 mg iron per 100 g dry-weight. Absorption of the non-heme electrolytic iron ranges from 5-10% so that most of the residual iron enters the colon. Normally excess iron is sequestered by a variety of mechanisms in the body, but there is no such system for the sequestering of iron in the gut lumen. The investigators have shown that providing iron supplements to adults where the majority of the iron is unabsorbed passes through the digestive tract can lead to the generation of ROS in the colon. These effects are seen in adults receiving 1 mg/kg/day supplemental iron. By 5-6 months of age infants consuming iron fortified cereals will receive the same dose and are likely producing ROS in their digestive tract. This may cause inflammation and make infants more susceptible to disease. The investigators think that meats and infant cereals with phenolic antioxidants available from fruits will likely reduce the generation of ROS in vivo. Therefore the investigators wish to determine if traditional and newly recommended first foods are safe from a free radical and inflammatory perspective. HYPOTHESES: 1. Consumption of infant cereals with iron will increase ROS generation in the gut 2. Consumption of infant cereals with iron and fruit will decrease ROS in the gut 3. Consumption of meat will not generate ROS 4. Consumption of iron fortified cereals or meat will maintain iron status during infancy
The purpose of this study is to explore the efficacy of Iocide oral rinse in a human clinical trial of gingivitis. Iocide oral rinse will be evaluated against a placebo rinse. Indices for gingivitis, plaque and bleeding will be scored and blood tests will be performed to determine the effect of the antimicrobial oral rinse on relative levels of biological markers of inflammation.
