Filter by:This study investigates the effect of acute walnut consumption on the cognitive behaviour, mood, brain activation, and markers of inflammation in young adults. In a within subjects design participants will receive a 50 g walnut or placebo intervention in a randomised order with a one week washout between interventions.
A study to find the relationship between neutrophil to lymphocyte ratio (NLR) with diaphragm thickness of critical patients in ICU.
People with Type 1 diabetes (T1DM), type 2 diabetes (T2DM) and healthy volunteers will undergo a hypoglycaemic clamp to to investigate the effect of hypoglycaemia on cardiovascular and inflammatory responses.
The composition of a food or a meal consumed plays an important role in the rate of postprandial endocrine and metabolic response, especially if high in fats, sugars and total energy content and a reduction in its entity is related to beneficial effects towards the prevention of several chronical diseases. The physiological postprandial response depends on several factors, both intrinsic, such as natural characteristic of food, and extrinsic, such as the way in which food is processed. This study aims at investigating postprandial hormonal, metabolic, oxidative stress, inflammation and endotoxaemia responses after the consumption of different commercial confectionary products made with different reformulation (ingredients and/or processing techniques).The principal scope of the study is to evaluate the impact of the reformulation of different snacks on postprandial responses. The investigators therefore designed a randomized controlled crossover trial, in which 15 healthy volunteers will consume different isocaloric confectionary products (snacks) and their related reformulation (total products number = 6) and a reference snack. Venous blood samples will be collected until 4-h after meal consumption. In order to evaluate postprandial hormonal, metabolic, oxidative stress, inflammation and endotoxaemia responses several markers will be evaluate: - metabolic substrates: glucose; Triglycerides and NEFA; - hormones: insulin; c-peptide; GLP-1, GIP, leptin, ghrelin, PYY; - markers of inflammation: IL-6, IL-8, IL-10, IL-17, TNF-α, hsCRP, MCP-1; - markers of oxidative stress and antioxidant capacity: GSH, FRAP; - endotoxaemia: lipopolysaccharides (LPS). These results will contribute to a detailed evaluation of the effects of reformulation on physiological events after meal consumption, leading to clarify if these variations in ingredients and/or processing techniques can modify postprandial responses, making them more similar to those originated from the reference snack.
Our proposed study is a 5-d double-blind randomised cross-over trial, seeking to simulate a training identification camp in competitive adolescent soccer players The purpose of the proposed study is to investigate whether increased protein consumption by Greek yogurt, compared to an isoenergetic carbohydrate (CHO) control supplement, consumed immediately following exercise training, prior to sleep and between breakfast and lunch, for a week during an intense training period (high volume, high intensity) will: - Attenuate the pro-inflammatory response (cytokines, acute phase proteins) - Reduced the severity of muscle damage and impairment (creatine kinase) - Maintain performance Secondary outcome measures: - Increase bone turnover (in favour of formation)
Cystic fibrosis (CF) is characterized by a decrease in mucociliary clearance, recurrent infections and airway inflammation. This inflammatory process in airway mucosa is persistent, uncontrolled, but, somewhat paradoxically, ineffective for pathogen clearance. Neutrophils are chronically recruited in the airway mucosa by proinflammatory mediators such as Interleukin (IL)-17. However, mechanisms involved in this dysregulated and persistent immune response are not well understood. In this context, a heterogeneous subpopulation of T lymphocytes called "unconventional T cells" (UTC) should deserve greater attention. UTC play a key role in orchestrating the ensuing innate and adaptive immune responses and they are endowed with numerous regulatory and effector properties. UTC mainly establish residency at mucosal sites, including the lung. To date, however, data related to implication and behavior of UTC during cystic fibrosis are extremely limited. The hypothesis is that, given UTC properties, their functions and behavior are altered in CF, and thus, these cells could be implicated in persistent inflammation and poor response to infections. The objective is to study UTC properties and functions in cystic fibrosis using blood and sputum samples of patients with CF, in correlation with comprehensive clinical and microbiological data. The study will enroll adult patients with CF followed-up at University Hospital of Tours, France. For each patient included, blood and sputum samples will be analyzed during 18 months 1/ from routine tests obtained at steady state and 2/ from tests performed during acute exacerbations. UTC will be explored in blood and sputum using flowcytometry approach, to evaluate their relative abundance, activation/inhibition profile and functions (cytokine production and cytotoxic ability). Correlation will be made with clinical status, with longitudinal comparison across the study period for each patient, and comparison with the other patients and healthy volunteers. This study will add significant knowledge in CF immunopathology by comprehensively assess UTC presence, functions and activation in CF. Indeed, UTC could be explored for disease progression marker, and, in a long-term perspective, explored for therapeutic interventions aiming at modulating their function (by activating or inhibiting UTC), to reshape lung immune response during CF.
Childhood gastroenteritis establishes gastrointestinal disease and increase the economic burden, and the pediatric population is especially vulnerable to these gastrointestinal infections. The aim of this study is to evaluate the role of intestinal microbiota and their relationship with childhood gastroenteritis.
This study compared traditional concept of preoperative fasting before elective open colon surgery and preoperative treatment with carbohydrate oral drink in intention to improve postoperative stress response to surgical procedure. Hypothesis was: preoperative oral carbohydrate drink reduces postoperative insulin resistance, improves insulin sensitivity, reduces postoperative inflammatory response in terms of the value of Glasgow Prognostic Score (GPS) and IL-6, improves postoperative patient's subjective well-being and surgical clinical outcome.
Metformin has a well-established safety profile and it has become clear that metformin has additional salutary effects, including anti-inflammatory, anti-aging, and anti-thrombotic properties. In this study, subjects will provide both venous blood samples and stool samples in addition to completing cognitive and physiologic testing at baseline, throughout a 90 day exposure to metformin, and 30 days following exposure to metformin in order to evaluate their immune, microbiome, cellular respiration, thrombotic, and inflammatory responses.
The on-going randomized clinical trial TTM2 (Target Hypothermia Versus Targeted Normothermia After Out-of-hospital Cardiac Arrest, NCT02908308) investigates if there is a difference in mortality, neurological function or quality of life in comatose survivors after out-of-hospital cardiac arrest if treated (Group A) at target temperature of 33 oC or (Group B) by avoiding fever during the first 24 h. In this sub study, the effect of different target temperatures on cardiac and circulatory physiology is evaluated by echocardiography and pulmonary artery catheter. Tissue damage after cardiac arrest in part is caused by an activation of different parts of the inflammatory system (reperfusion injury). This study investigates the effect of temperature management on inflammation and the link to the circulatory effects.
