Assessment of Anti-HIV-1 Antibodies in Oral and Nasal Compartments of Volunteers From 3 Different Populations.

In this study, we assessed the feasibility of collecting standardized nasal and salivary samples at centers in Nairobi (Kenya), Kigali (Rwanda), and London (United Kingdom) using different collection devices and media (synthetic absorptive matrices versus flocked swabs, and Salimetrics oral swabs versus whole oral fluid collection). We detected anti-Gag (p24) and envelope (gp140) antibodies in both nasal fluid and salivary collections from all HIV-infected individuals, and cross-reactive anti-p24 antibodies were detected in 10% of HIV-uninfected individuals enrolled at one site. Collections from the nasal turbinates were comparable with samples collected deeper in the nasopharyngeal tract, and the yield of anti-p24 IgA in the whole oral fluid samples was higher than in samples collected from the parotid gland.

Increasing functional rehabilitation in acquired brain injury treatment: effective applications of behavioural principles.

This paper investigated ways to increase the participation of direct care staff in the functional rehabilitation activities (FRAs) of adults with acquired brain injuries (ABIs). FRAs were rehabilitation agendas written by clinical staff for delivery by paraprofessionals. Increases in FRA completion were believed to be directly related to clinical success.
