Active clinical trials for "Inflammation"

This study will provide the researchers with an opportunity for the investigation of the biomarkers and different human biology component variable interactions in children; information that can generate new correlations between markers not known at the moment. Regarding their analysis, variation could have multiple connotations. A categorical that refers to a specific state, established with a diagnostic standard. And a numerical, referring to a range or the absolute value limits in a continuous spectrum; this research will allow us to express variability in the distance amplitude of the obtained values level, as well as classifications or categories previously established in the possible cases. OBJECTIVES PRINCIPAL OBJECTIVE To estimate the inter and intra-individual variety in a selected series or biological variables determinant of growth, body composition, infection, oxidation, inflammation and hydration, in preschool children sharing the same institutional-based diet. SPECIFIC OBJECTIVES To determine the inter and intra-individual variation of growth in preschool children, with a similar diet, who attend Secretariat of Beneficial Works of the First Lady system daycare centers and to compare between semi-urban and rural. To describe the inter-individual variation of the red blood cells circulating mass in preschool children, with a similar diet, who attend day care centers and to compare between semi-urban and rural. To determine the inter-individual variation of systemic and intraintestinal oxidation in preschool children, with a similar diet, who attend daycare centers and to compare between semi-urban and rural. To describe the inter-individual variation of systemic and intraintestinal inflammation in preschool children, with a similar diet, who attend daycare centers and to compare between semi-urban and rural. To determine the inter and/or intra-individual variation of urinary tract infection and gastrointestinal parasite infestation in preschool children, with a similar diet, who attend daycare centers and to compare between semi-urban and rural. To describe the inter and intra-individual variation of the hydration status in preschool children, with a similar diet, who attend daycare centers and to compare between semi-urban and rural. To explore intra-individual associations in variables of the same research component or different component variables.

The purpose of this study is to determine long term healing rates of chronic venous ulcers (CVU) after ultrasound-guided foam sclerotherapy (UGFS) of superficial venous reflux (SVR) and to relate recurrence of CVU to evidence of recanalisation and the presence of superficial or deep venous reflux

Hypothesis;Aging modifies the risk of pulmonary dysfunction in HIV+ individuals. The study is a multicenter, prospective observational study of aging and pulmonary function in HIV. The investigator will determine the prevalence and risk factors for lung dysfunction as quantified by pulmonary function testing in both younger (<50 years) and older (≥50 years) HIV+ and HIV-uninfected controls. The investigator will build on existing cohorts and enrich enrollment for individuals over the age of 50 while adjusting for important co-variates such as ART, smoking history, co-infections, and illicit drug use. Evaluations will be scheduled at baseline, 18 months, and 36 months. Study visits will consist of blood draw, questionnaires, and pulmonary function testing.

The purpose of this study is to find out if there is a link between cigarette smoking, inflammation and the spread of breast cancer to the lung. We think that women who are current or former smokers may be at increased risk for breast cancer spreading to the lung compared to women who have never smoked. Smoking causes inflammation in the lung in some women. Researchers at Memorial Sloan-Kettering (MSKCC) think that smoking-related lung inflammation may increase the chance of breast cancer spreading to the lung. In order to find out whether inflammation plays a role in breast cancer spreading to the lung, we will measure a urinary marker of lung inflammation. This will allow us to determine if this marker is more commonly elevated in women with breast cancer that has spread to the lung compared to those without breast cancer in the lung. We will also collect DNA from blood to have the opportunity to determine if there are differences in DNA in women with or without breast cancer that has spread to the other sites including the lung. We will also collect blood to determine if we can identify risk factors for the spread of breast cancer to the lungs.

Myeloid-derived suppressor cells (MDSC) have been studied for their ability to suppress T cell responses in vivo and in vitro. As a result, MDSC can regulate cellular responses to chronic inflammatory conditions such as cancer, leading to the induction of tolerance and, ultimately, tumor escape from immune surveillance.

The purpose of this study is to characterise the clinical features, histopathology and the treatment outcomes of patients with idiopathic orbital inflammation syndrome.

Asthmatics have inflammation in the large airways (tubes through which air travels in and out of the lungs). The large airways are located in the central lung. New research shows that asthmatics also have inflammation in the small airways. The small airways are located in the peripheral lung (the parts of the lung away from the central lung). Until now, most of the inhaled medications available have been made up of big particles that never reach the peripheral lung. The purpose of this study is to try to measure the level of inflammation in the peripheral lung in asthmatics and see if this inflammation can be decreased with different types of inhaled corticosteroids. The investigators will check airway inflammation before and after use of an inhaled corticosteroid that has a large particle size and should only reach the large airways (Flunisolide-CFC), and before and after use of an inhaled, small particle corticosteroid that should reach both the large and small airways (Flunisolide-HFA). Subjects will make 6 study visits over two phases of the study. In the first phase, the investigators will collect baseline information about subjects while they are using placebo (inactive substance). In the second phase, subjects will take either the large or small particle corticosteroid. Visits will involve questionnaires and various tests measuring lung function (such as spirometry, forced oscillation, and methacholine challenge). Exhaled nitric oxide will be measured as an indication of inflammation. Subjects will also measure and make note of lung function at home twice daily using a peak expiratory flow meter. Two of the visits will involve fiberoptic bronchoscopy so that the investigators may collect cells and tissue samples without surgery. Another two of the visits will involve the use of high resolution computed tomography (HRCT) scans to indirectly evaluate disease in distant parts of the lungs.

Studies have shown that the prevalence of respiratory symptoms, airway hyperresponsiveness (AHR) and asthma is high and increasing in elite athletes. The inflammation seen in the airways of elite athletes might differ from the inflammation seen in the airways of "ordinary" asthmatics and it might represent a different kind of asthma. The primary purposes are To investigate the type of airway inflammation in young swimmers. To investigate the acute changes in airway inflammation after a short training session.

Chronic kidney disease (CKD), is characterized by accelerated development of atherosclerosis and advanced remodelling of vessels and the heart. It is associated with many factors, including inflammation, arterial hypertension, hyperlipidemia, hyperhomocysteinemia, secondary hyperparathyroidism, and oxidative stress. Hypertension is one of the most critical risk factors for cardiovascular complications. It leads to the formation of structural changes in the vascular system: it impairs the activity of the endothelium, causes hypertrophy and remodelling of the vascular wall, reduces the susceptibility of the vessels and accelerates the development of atherosclerosis. This study aimed to identify the processes and their representative markers, the concentration of which in the serum may reflect the cardiovascular system status and can predict the increased mortality in HD patients.

The purpose of this study is to measure arterial 99mTc-Tilmanocept uptake using single photon emission computed tomography (SPECT/CT) scanning in HIV infected subjects known to have subclinical coronary atherosclerosis as assessed by contrast-enhanced coronary computed tomography angiography (CCTA).
