Plasma sRAGE is independently associated with increased mortality in ARDS: a meta-analysis of individual patient data

The soluble receptor for advanced glycation end-products (sRAGE) is a marker of lung epithelial injury and alveolar fluid clearance (AFC), with promising values for assessing prognosis and lung injury severity in acute respiratory distress syndrome (ARDS). Because AFC is impaired in most patients with ARDS and is associated with higher mortality, we hypothesized that baseline plasma sRAGE would predict mortality, independently of two key mediators of ventilator-induced lung injury. We conducted a meta-analysis of individual data from 746 patients enrolled in eight prospective randomized and observational studies in which plasma sRAGE was measured in ARDS articles published through March 2016. The primary outcome was 90-day mortality. Using multivariate and mediation analyses, we tested the association between baseline plasma sRAGE and mortality, independently of driving pressure and tidal volume. Higher baseline plasma sRAGE [odds ratio (OR) for each one-log increment, 1.18; 95% confidence interval (CI) 1.01-1.38; P = 0.04], driving pressure (OR for each one-point increment, 1.04; 95% CI 1.02-1.07; P = 0.002), and tidal volume (OR for each one-log increment, 1.98; 95% CI 1.07-3.64; P = 0.03) were independently associated with higher 90-day mortality in multivariate analysis. Baseline plasma sRAGE mediated a small fraction of the effect of higher Delta P on mortality but not that of higher V (T). Higher baseline plasma sRAGE was associated with higher 90-day mortality in patients with ARDS, independently of driving pressure and tidal volume, thus reinforcing the likely contribution of alveolar epithelial injury as an important prognostic factor in ARDS.

Contamination of the Burňa watercourse, by a dumps complex

Abstract This article dealing with the problematic contamination surface water in dumps complex and there were monitoring basic physical and chemical parameters, toxic and strategic metals. There were analysed inorganic ions NH4, Cl, SO4, NO3, NO2 by standard laboratory analysis, and the elements Pb, Cd, Cr, Cu, Ni were measured by method ICP MS, and elements Zn, Fe, Mn, Na by method AAS. The case study of the contamination in the Burňa watercourse basin, in industrial landscape of the Ostrava city is unique in solving the problem of ecological burdens of the Ostrava city. One year of monitoring case study showed a significant load on the watercourse with the expected contamination especially by toxic metals. The surface water Burňa watercourse was affected by a dumps complex and their chemistry. The source of the contamination is the impact of former mining, in this post-mining landscape.</jats:p

Host response biomarkers in sepsis: the role of procalcitonin.

Procalcitonin is the prohormone of calcitonin and present in minute quantities in health. However, during infection, its levels rise considerably and are correlated with the severity of the infection. Several assays have been developed for measurement of procalcitonin levels; in this article, we will briefly present the PCT-sensitive Kryptor(®) test (Brahms, Hennigsdorf, Germany), one of the most widely used assays for procalcitonin in recent studies. Many studies have demonstrated the value of procalcitonin levels for diagnosing sepsis and assessing disease severity. Procalcitonin levels have also been successfully used to guide antibiotic administration. However, procalcitonin is not specific for sepsis, and values need to be interpreted in the context of a full clinical examination and the presence of other signs and symptoms of sepsis.info:eu-repo/semantics/publishe
