Filter by:Sepsis is a dysregulated host response to severe life-threatening infections, leading to organ failure and death in up to 40% of patients with septic shock. Pulmonary infections are the main cause of community-acquired sepsis and frequently lead to the development of acute respiratory distress syndrome(ARDS). Features of immunosuppression, including diminished cell surface monocyte human leukocyte antigen DR (mHLA-DR) expression, are strongly associated with hospital mortality. Such decrease in HLA-DR expression on antigen-presenting cells has been associated with impairment of microbial antigens to Tcells. Septic patients also show elevated expression of inhibitory receptors associated with cell exhaustion.. Yet, biochemical, flow cytometric and immunohistochemical findings consistent with immunosuppression have been observed in lungs and spleen of patients died of sepsis and multiple organ failure, demonstrating the relevance of studying these defects directly in organ tissues. A novel approach aimed to characterize the role and prognostic value of alveolar biomarkers measured directly in the injured lungs is warranted and supported by: -disappointing results of previous clinical trials attempting to restore the level of biomarkers measured on circulating cells; -evidences of regional immunosuppression in lungs of ARDS patients; -lung is the main site of hospital-acquired infections with a prevalence of ventilator-associated pneumonia in 30% over the course of Intensive Care Unit(ICU) stay in ARDS patients. Investigators speculate that biomarkers measured on alveolar leukocytes (AL) surface, are important predictors of outcome and potential therapeutic targets in ICU patients with pneumonia-associated ARDS. Investigators aim to explore whether biomarkers measured directly on AL from patients with pneumonia-associated ARDS are associated to regional pulmonary immunosuppression using leukocyte functional tests; and predictors of outcomes. Bronchoalveolar lavage fluid(BALF) and blood samples will be collected in ARDS patients. Leukocyte populations and cell membrane biomarkers will be quantified using flow cytometry. Leukocyte functional tests will be performed ex vivo on leukocytes collected from BALF and blood samples. Pharmacological interventions will be performed ex vivo. This project aims to identify biomarkers associated with outcomes and potential therapeutic targets.
This study aims to provide an estimate of the incidence of paraneoplastic neurological syndromes and autoimmune encephalitides in France between the years 2016 and 2018. The study will describe the incidence of antibody subtypes and regional variations.
To investigate the feasibility of Duplex US in Diagnosis of Pelvic Congestion Syndrome
The comprehensive analysis of health records, TCM constitution, biomarker, and whole-genome sequencing among dry eye syndrome, healthy control, Sjögren's syndrome and other inflammation disease in Taiwan: an integrated analysis between Taiwan Biobank and Sjögren's syndrome Database
The main purpose of this study is to investigate the feasibility of a follow-up larger RCT on the efficacy of Botanical Tincture to relieve abdominal pain in people with Irritable Bowel Syndrome Constipation Predominant (IBS-C).
Characterization of the genetic causes, and of the immunopathological clinical and biological manifestations in children with pediatric Evans syndrome included in a prospective national observational cohort of rare diseases.
To evaluate the short term out comes of the polymer free stents in patients presented with non ST elevation acute coronary syndrome (which include ST depression myocardial infarction and unstable angina ) after percutaneous coronary intervention .
This study evaluates the efficacy of intensive surveillance, prevention and treatment of intra-abdominal hypertension in ICU patients. In the first two months patients will be screened and undergo usual care. In the following 10-months patients will have more intensive screening and active measures towards prevention and treatment according to best practices.
A total of 400 participants will be recruited: 200 patients with suspected OSAS will be recruited from the sleep clinic (OSAS group), 100 patients diagnosed with dizziness will be recruited from the ENT clinic (Dizziness group). In addition, 100 patients with no dizziness and no evidence for OSAS will be recruited from both the sleep clinic and the ENT clinic (controls). Informed consents will be completed by all participants. ). In order to assess the effect of treatment of OSAS on dizziness -patients with the diagnosis of OSAS will complete validated questionnaires regarding sleep, dizziness and eustachian tube function 3 months following initiation of treatment with CPAP
The current study will test the central hypothesis that Glycine supplementation in humans improves Lipid profile and therefore reduces the risk of Atherosclerosis. Secondary outcomes including Insulin sensitivity and parameters related to Metabolic Syndrome (MetS) will also be measured. Furthermore, a mechanistic study in an ex-vivo model will test the hypothesis that Glycine via its key biosynthetic pathway involving Serine Hydroxymethyltransferase 2 (SHMT2), is athero-protective by inhibiting Sterol regulatory element-binding protein 2 (SREBP2)-mediated cholesterol biosynthesis in murine macrophage-like cell line.
