Filter by:This study aims to identify the prognostic role of procalcitonin (PCT), soluble Triggering Receptor Expressed on Myeloid Cells-1 (sTREM-1), the soluble form of the urokinase plasminogen activator receptor (suPAR), highly sensitive C-reactive protein (hs-CRP), Interleukin-6 (IL-6), and azurocidin 1 (AZU1) in 28-day mortality for patients with sepsis in Emergency Department.
There are currently no minimally invasive techniques for the measurement of lipopolysaccharide (LPS) and Apo-B48 that can be used in samples collected in field settings. In this project we want to explore whether postprandial assessment of biomarkers LPS and ApoB48 in blood withdrawn with a finger prick test can be used as marker for low grade inflammation and risk factor for CVD. The primary objectives of this pilot study are to a) determine whether postprandial LPS and ApoB48 levels can be assessed in finger prick blood of both lean subjects and obese subjects; and b) compare postprandial LPS and ApoB48 levels assessed in venous blood and blood collected through a finger prick test. This study is an observational pilot study in which postprandial LPS and ApoB48 will be assessed before and after ingestion of a high fat load in 5 lean and 5 obese subjects in the age range 18-70 years. Samples will be collected under fasting conditions and in response to a high fat challenge test (1, 2, 4 and 6 hours post ingestion). The risks for participation are very small if not negligible. No adverse effects of the high fat challenge were reported previously. Consumption of high amounts of saturated fat may cause some GI discomfort. Blood sampling will be performed via a cannula and the insertion can be a painful and may cause a bruise. Finger prick might also give a short pain sensation and small bruises. The amount of blood that is drawn from participants is relatively small (total 37.5 ml) and is therefore within acceptable limits. There are no direct benefits for the participants. In the BIOLOGIC study we include both lean subjects and obese subjects as we expect differences in postprandial responses related to differences in chylomicron production and LPS levels. Therefore it is important to explore these biomarkers in both target groups. This study can therefore be regarded as group-related, non-therapeutic research.
Collect blood from patients admitted for coronary angiography to tubes with heparin, centrifuge and collect plasma. This will be frozen at -80C. Sent to the Lipotype laboratory, Dresden, Germany, for the detection and quantification of compounds derived from oxidized LDL cholesterol (cholesterol hemi-esters).
Multiple Sclerosis (MS) characterized by demyelination and axonal degeneration is a chronic inflammatory disease of the central nervous system (CNS). Recent studies have shown that dysregulated miRNAs alter immune responses, so they may have roles basis on various genetic diseases such as MS and may be potential targets for biomarkers and new therapeutic approaches. In this study, we evaluated the dysregulation of miRNA expression levels at MS and MS stages. We also discussed the potential of these miRNAs to be biomarkers and/or therapeutic targets in MS.
The investigators design a prospective clinical study to explore the efficacy and safety of apatinib plus camrelizumab in pretreated patients with advanced biliary tract malignant tumors and to analyze potential biomarkers of therapeutic response.
Chronic wounds represent a growing challenge in medical care. Part 1: The aim of this part of the study was to collect wound swabs and to answer the question whether the rapid diagnostic tool using enzyme activities can display an infection prematurely. This means that an increased enzyme activity (especially MPO, NHE, LYS, gelatinase, pH) measured overed 3 days, would indicate a change in the wound bed (infection, Inflammation) earlier than the regularly performed clinical assessment. Part 2: The aim of this part of the study was to evaluate (I) the possibility of wound fluid acquisition by means of an "additional collector" during ongoing NPWT and to answer if (II) this secretion can be biochemically analyzed for enzyme activities in order to be able to detect a change in the wound situation at an early stage.
The purpose of this study is to validate the screening protocol to study risk factors of exercise-induced bronchoconstriction (EIB) obtained in our previous study in high-school elite athletes (NCT03587675), in recreational young athletes who perform intense physical exercise.
International, multicenter, observational, longitudinal study to identify or monitor Inborn Error of Metabolism disease biomarkers and to explore the clinical robustness, specificity, and long-term variability of these biomarkers
