The study of the health status in long-living individuals (LLIs) may help identifying health-span and life-span determinants. BPI-Fold-Containing-Family-B-Member-4 (BPIFB4) protein is higher in healthy vs. non-healthy (frail) LLIs serum and its longevity-associated variant forced expression improves cardiovascular outcomes in ischemia mice models. Thus, we tested the association of BPIFB4 and ischemia-responding HIF-1α pathway components (i.e. CXCR4, AK3, ALDO-C, ADM, VEGF-A, GLUT-1 and miR-210) with human life-span and healthspan by analyzing mRNA expression in circulating mononuclear cells (MNCs) of LLIs (N=14 healthy; N=31 frail) and young controls (N=63). ALDO-C, ADM, VEGF-A and GLUT-1 significantly decreased and miR-210 increased in LLIs vs. controls. Only VEGF-A and GLUT-1 showed further significant reduction in healthy-LLIs vs. frail-LLIs comparison. While BPIFB4 and CXCR4 were similar between LLIs and controls, BPIFB4 was significantly higher and CXCR4 lower in healthyversus frail-LLIs. On a new set of LLIs (N=7 healthy and N=5 non-healthy) we assessed a potentially correlated function with low CXCR4 expression. Healthy donors' MNCs showed efficient migration ability toward CXCR4 ligand SDF-1α/CXCL12 and high percentage of migrated CXCR4pos cells which inversely correlated with CXCR4 RNA expression. In conclusion, BPIFB4 and CXCR4 expression classify LLIs health status that correlates with maintained MNCs migration.

Cognitive impairment is a frequent complication of stroke. The aim of this study was to evaluate the effectiveness of cognitive training performed early after stroke. Ninety-two patients were randomly assigned to either the study group (SG) or the control group (CG). Cognitive rehabilitation consisted of 16 individual one-hour sessions in which patients performed therapistguided computer exercises. The patients in the CG performed a sham intervention. After four weeks all the patients were re-evaluated. In the SG, significant improvements (p<0.05) were detected in all neuropsychological measures at the post-training evaluation, while the CG showed mild (not statistically significant) improvements on cognitive tests. Between-group analysis revealed statistically significant differences in the domains of memory and visual attention. Cognitive training performed early after stroke seems to be a viable option for improving cognitive outcome in stroke survivors. Further studies should assess whether this may favor their reintegration into everyday life. © 2014, CIC Edizioni Internazionali s.r.l. All rights reserved.
