Filter by:Prediabetes, characterized by elevated fasting blood sugar or exaggerated blood sugar response to sugar ingestion, effects over 79 million adult Americans and is a precursor to the development of Type 2 diabetes. Importantly, approximately 42% of Iowans (950,000) have diabetes and 32% (670,000) have prediabetes with the majority of those with prediabetes going undiagnosed. Adults with prediabetes demonstrate early signs of cardiovascular and nervous system abnormalities and are at high risk for developing overt diabetes unless aggressive lifestyle (weight loss, exercise) or pharmacological interventions are employed. Interestingly, data in recent years has linked obesity and diabetes to chronic inflammation of the blood vessels and brain areas that regulate blood pressure. Therefore, the current study will test whether a commonly used aspirin-like anti-inflammatory drug called salsalate, will improve blood vessel health and nervous system dysfunction in adults with prediabetes. Eligible subjects will have measurements of blood pressure, blood vessel function in the arms and eyes, assessments of nerve activity, and blood samples taken before and after 4 weeks of ingesting an FDA approved aspirin-like drug called salsalate. The study is important because it will identify a potentially new pharmacological strategy to treat vascular and nervous system abnormalities in overweight and obese adults with early stage type 2 diabetes using an inexpensive, generically available drug with an excellent safety record that has been used for decades to treat chronic inflammatory conditions such as rheumatoid arthritis. If proven effective, this will provide preliminary support for the concept of targeting inflammation as a new clinical approach to treating early diabetes related complications. Furthermore, the current pilot study will provide support for developing a larger clinical trial using salsalate that could potentially then be extended to patients with type 2 diabetes and cardiovascular disease, as well as lead to the development of new anti-inflammatory agents with greater specificity for selective inflammatory pathways.
The purpose of this study is to determine whether docosahexaenoic acid (DHA) is effective in the treatment of periodontitis in adults.
The general objective of this project is to investigate the acute effect of consuming a dietary supplement combining resveratrol and curcumin on the inflammatory response following the consumption of a high-fat meal in healthy subjects with slightly elevated waist circumference. The study will be undertaken according to a double-blind, cross over, randomized, placebo controlled design and will be conducted at the Institute of Nutrition and Functional Foods (INAF) of Laval University. The study will involve a total of 20 healthy subjects (10 men and 10 women. Included subjects will undergo an 6-hour oral fat tolerance, on two separate occasions (one time following dietary supplement consumption and one time following consumption of a placebo). The two test days will be separated by maximum of two weeks. The outcomes are the changes in the plasma levels of inflammatory cytokines in their gene expression.
The purpose of this study is to determine the relationship between thoracic aortic inflammation and arterial stiffness in elderly patients. Vascular-aging is accompanied by a gradual remodeling affecting both cardiac and arterial walls. Arterial hypertension, an established cardiovascular risk factor, has been suggested to exert pro-inflammatory actions threw several biological mediators enhancing arterial stiffness. Both effects of aging and hypertension are associated with higher levels of arterial stiffness, but their respective role is not well established in the pathophysiology of arterial stiffening. Few data are available neither on the real anatomic aortic impact of aging and hypertension on aortic compliance and ventricular function and its relationship to arterial stiffness assessed by carotid-femoral pulse wave velocity, nor on the reliability of cine phase contrast magnetic resonance imaging arterial stiffness measurements. Recent studies using positron emission tomography imaging (PET) with 18 F fluorodeoxyglucose (FDG) has been advocated as a means of measuring arterial wall inflammation in various population referred for oncology staging. FDG uptake is correlated with the number of cardiovascular risk factors and even the risk of future cardiovascular events. This method, combined with X-ray computed tomography (CT), has also demonstrated that aortic calcifications quantified by CT and local signs of inflammation detected by FDG uptake contribute to arterial stiffness. A strong relationship between large vessels stiffening assessed by carotid-femoral pulse wave velocity measurement, aortic calcifications quantified by CT and inflammation evaluated by FDG uptake has been demonstrated. Therefore, in the current study, we use FDG PET associated to CT to characterize aortic inflammation and aortic calcifications coupled to pulse wave velocity measurement and cardiac function in elderly individuals. In fact, if vascular aging promoting a local inflammatory process is a risk factor for cardiovascular disease, then vascular changes assessed by non-invasive vascular imaging (MRI,FDG PET) could represent a potential target for treatment and prevention Thirty individuals ≥ 65 years of age were examined, 15 hypertensive subjects and 15 controls. Pulse wave velocity, a surrogate for aortic stiffness, was measured both by cine phase contrast magnetic resonance imaging and applanation tonometry. Brachial pulse pressure, carotid calculated pulse pressure and pulse pressure amplification (brachial to carotid ratio), predictors of cardiovascular mortality were also quantified. Thoracic aorta local inflammation and calcification were measured by 18 F-fluorodeoxyglucose positron emission tomography/computed tomography imaging. Moreover, biomarkers of low grade inflammation (high-sensitivity C-reactive protein, interleukin 6 were also determined).
Cystic fibrosis (CF) is a complex systemic disease that mainly involves the respiratory and gastrointestinal (GI) tracts. The polymicrobial community composition of respiratory and GI tracts is influenced by both genetic and environmental factors. Children with CF may harbor an abnormal intestinal microflora, because of altered Cystic fibrosis transmembrane conductance regulator (CFTR) function and heavy drug load (antibiotics, pancreatic enzymes and acid suppressors). The investigators previously demonstrated that intestinal inflammation is highly frequent in CF children, being a major feature of intestinal involvement. In addition, specific probiotics significantly improved airway and GI inflammation in a preliminary trial. The aim of the study is to characterize intestinal and respiratory microflora in CF patients and to investigate the effects of daily Lactobacillus GG (LGG) supplementation on both GI and airway microflora and the eventual relationship between probiotic assumption and clinical and inflammation markers. The aim is to study the effect of microflora modification on intestinal and extraintestinal inflammation to eventually improve the quality of life of CF patients, who often suffer from intestinal and respiratory progressive disease, through a non invasive intervention consisting in the supplementation of probiotic bacteria.
In patients that require a dental implant, does zirconia compared to titanium, or cad-cam acrylic abutments, provide less inflammation, marginal bone loss or infection during the osseointegration period ?
This trial is conducted in Europe. The aim of the trial is to investigate the safety, tolerability, pharmacokinetics (exposure of the trial drug in the body) and pharmacodynamics (the effect of the investigated drug on the body) of NNC0215-0384 administered to subjects with moderate to severe rheumatoid arthritis (RA) concomitantly treated with methotrexate (MTX).
This study investigates the efficacy of a proprietary probiotic formulation comprising 6 strains of bacteria in reducing inflammation and gingivitis in pediatric patients between 11 and 18 years old undergoing orthodontics treatment. Patients will be recruited based on a prior diagnosis of mild to moderate gingivitis by gingival index score. Participants in this study will be randomly assigned to receive either the probiotic treatment or a placebo, both in the form of a dissolving lozenge; for which the placebo is exactly the same shape, texture, taste, and composition as the probiotic treatment, but does not contain the active probiotic ingredients. The lozenges are to be taken orally at a certain prescribed regimen for 28 days. Participants will be assessed for gingivitis scores, gum bleeding scores, plaque scores, overall periodontal health, and for precarious areas at baseline, 14, and 28 days. They will also be assessed for the same measures at day 56, following a 28-day wash-out phase. Plaque and saliva samples will be collected at all timepoints for in vitro analyses of changes in microbial pathogens and/or inflammatory cytokines.
Melasma is an acquired hyperpigmentary disorder that commonly affects women from Asia and Latin-America.There is evidence of subclinical inflammation supported by diffuse spectrometry and by prominent inflammatory cells in affected areas; however this infiltrate and its inflammatory mediators remains unexplored. Chronic inflammation induces melanogenesis and angiogenesis; thus, it could be linked to its recurrent nature.Therefore, the aim of this study is to describe the inflammatory cellular infiltrate, and the expression of main inflammatory and angiogenic mediators in this condition, as well as to explore its relationship with severity of disease. Using histological, histochemistry, immunohistochemistry, and quantitative real-time PCR, we evaluated melasma lesions from 20 healthy female patients with malar melasma without specific solar exposure or photoprotection measures within the previous 3 weeks and compared them to non lesional skin.
This is a transversal double-centre study. Patients will be recruited from outpatient consultations. They will have buccal inflammation caused by periodontal disease (frequent oral infections, mostly with GRAM (-) bacteria). Three groups of 80 patients, corresponding to slight, moderate and severe periodontal disease, will be formed according to the results of radiological and clinical examinations.
