[Conclusion] The study suggests that subjects’ ability to descend stairs is lessened with the addition of the concurrent secondary attention-demanding task, and that the addition of divided attention
tasks places an apparently higher demand on balance control that may prove to be challenging for subjects at high risk of falling.”
“The 2011-2012 and 2012-2013 post-pandemic influenza outbreaks were characterized by variability in the A(H3N2) influenza viruses, resulting in low to moderate vaccine effectiveness (VE). The aim of this study was to investigate the molecular evolution and vaccine strain match of the A(H3N2) influenza viruses, having been circulated throughout the population of the French Corsica RG-7112 ic126 Island in 2011-2012 and again in 2012-2013. Clinical
samples from 31 patients with confirmed A(H3N2) influenza viruses were collected by general practitioners (GPs) over these two consecutive seasons. An analysis of genetic distance and antigenic drift was conducted. Based on a hemagglutinin (HA) aminoacid sequence analysis, the Corsican A(H3N2) viruses fell into the A/Victoria/208/2009 genetic clade, group 3. All influenza viruses were characterized by at least four fixed amino acid mutations which were: N145S (epitope A); Q156H and V186G (epitope B) Y219S (epitope D), with respect to the A/Perth/16/2009 (reference vaccine find more strain for the 2011-2012) and the A/Victoria/361/2011 (reference vaccine strain for the 2012-2013). Using the p(epitope) model, the percentages of the perfect match VE estimated against circulated strains declined within and between seasons, with estimations of smaller than 50%. Overall, these results seem to indicate an antigenic drift of the A(H3N2) influenza
viruses which were this website circulated in Corsica. These findings highlight the importance of the continuous and careful surveillance of genetic changes in the HA domain during seasonal influenza epidemics, in order to provide information on newly emerging genetic variants.

“The aim of the present study was to characterize traumatic deaths of major trauma patients occurring in a university trauma centre and to assess retrospectively the quality of given care by evaluating whether any of the deaths could be identified as potentially preventable. All consecutive deaths of trauma patients between January 1, 2004 and December 31, 2008 in the Toolo Hospital Trauma Centre were retrospectively reviewed. The inclusion criterion was death of a trauma patient occurring during stay at hospital.
