Background: The aim of this study is to determine the 99th upper-reference limit (URL) for cardiac troponin T (cTnT) in Italian apparently healthy subjects. Methods: The reference population was selected from 5 cities: Bolzano (n = 290), Milano (CAMELIA-Study, n = 287), Montignoso (MEHLP-Study, n = 306), Pisa (n = 182), and Reggio Calabria (MAREA-Study, n = 535). Subjects having cardiac/systemic acute/chronic diseases were excluded. Participants to MEHLP project underwent cardiac imaging investigation. High-sensitive cTnT was measured with Cobas-e411 (Roche Diagnostics). Results: We enrolled 1600 healthy subjects [54.6% males; age range 10-90. years; mean (SD): 36.4 (21.2) years], including 34.6% aged <20. years, 54.5% between 20 and 64 years, and 10.9% over 65 years. In the youngest the 99th URL was 10.9 ng/L in males and 6.8 ng/L in females; in adults 23.2 ng/L and 10.2 ng/L; and in elderly 36.8 ng/L and 28.6 ng/L. After the exclusion of outliers the 99th URL values were significantly decreased (P < 0.05) in particular those of the oldest (13.8 ng/L and 14 ng/L). MEHLP participants were divided in healthy and asymptomatic, according to known cardiovascular risk factors (HDL, LDL, glucose, C-reactive protein): the 99th URL of cTnT values of these subgroups was significantly different (19.5 vs. 22.7, P < 0.05). Conclusions: 99th URL of cTnT values was strongly affected by age, gender, selection of subjects and the statistical evaluation of outliers. © 2014 Elsevier B.V.

Background Vasostatin-1 (VS-1), the N-terminal fragment of chromogranin A (CgA), decreases the permeability of endothelial cells in vitro and in vivo. Aims Here, we investigated whether a similar effect could be observed also on intestinal epithelial cells (IECs) in vitro and whether VS-1 could have favorable effects on animal models of acute or chronic colitis, which are characterized by increased permeability of the intestinal epithelium. Methods In vitro, VS-1 was tested on IEC monolayers showing increased permeability, on mechanically injured IEC monolayers, and on the production of the chemokine IL-8/KC by lipopolysaccharide (LPS)-stimulated IECs. In vivo, VS-1 was tested in animal models of dextran sodium salt (DSS)-induced acute or chronic colitis. Results In vitro, VS-1 inhibited increased permeability of IECs induced by interferon-c and tumor necrosis factor-a. Moreover, VS-1 promoted healing of mechanically injured IEC monolayers, most likely through stimulation of cell migration, rather than cell proliferation. Eventually, VS-1 inhibited LPS-induced production of IL-8. In vivo, VS-1 exerted protective effects in animal models of acute or chronic colitis upon oral, but not systemic administration. Conclusions VS-1 is therapeutically active in animal models of acute or chronic, DSS-induced colitis. The mechanisms underlying this effect are likely to be multiple, and may include inhibition of enhanced intestinal permeability, repair of injured intestinal mucosae, and inhibition of the production of IL-8/KC and possibly other infammatory cytokines. © 2012 Springer Science+Business Media, LLC.

The objective of this study was to determine, in an adolescent population, the prevalence of nonalcoholic fatty liver disease (NAFLD) and the association of NAFLD and cardiovascular risk factors with carotid artery intima-media thickness (IMT), a marker of subclinical atherosclerosis. The authors conducted a population-based study among 642 randomly selected adolescents aged 11-13 years in Reggio Calabria, southern Italy, between November 2007 and October 2008. Prevalences of overweight and obesity were 30.5% and 13.5%, respectively. The overall prevalence of NAFLD was 12.5%, increasing to 23.0% in overweight/obese adolescents. In univariate analysis, increased IMT was positively associated with the presence of NAFLD, body mass index (BMI), waist circumference, systolic blood pressure (all P's < 0.001), diastolic blood pressure (P = 0.006), γ-glutamyl transpeptidase (P = 0.006), alanine aminotransferase (P = 0.007), and C-reactive protein (P = 0.008) and was inversely associated with high density lipoprotein cholesterol (P < 0.001). In multivariate analysis, NAFLD (P = 0.002), BMI (P = 0.004), waist circumference (P = 0.003), and systolic blood pressure (P = 0.005) retained significant associations. The authors conclude that NAFLD, BMI, waist circumference, and systolic blood pressure are independent markers of increased IMT in a random sample of adolescents. © The Author 2010.
