A mixed methods approach to delineating and understanding injection practices among clientele of a Victoria, British Columbia needle exchange program.

Introduction And Aims: Systematic reviews and meta-analyses show that needle exchange programs reduce HIV and HCV transmission for injection drug users (IDUs) but far less is known about the injection practices of IDUs enrolled in these programs. This study adopts a mixed methods approach to quantify high-risk injection practice patterns among IDUs enrolled in a needle exchange program in Victoria, British Columbia, Canada and gather qualitative data to understand underlying injection behaviour rationales and patterns.

Design And Methods: Survey data collected in 2008 from 105 IDUs registered as clientele of the AIDS Vancouver Island-Street Outreach Services (AVI-SOS) Needle Exchange were analysed via univariate and multivariate statistical methods.

Worry as a window into the lives of people who use injection drugs: a factor analysis approach.

Background: The concept of risk dominates the HIV/AIDS literature pertaining to People Who Use Injection Drugs (PWUID). In contrast the associated concept of worry is infrequently applied, even though it can produce important perspectives of PWUID's lives. This study asked a sample (n = 105) of PWUID enrolled in a Victoria, British Columbia needle exchange program to evaluate their degree of worry about fourteen factors they may encounter in their daily lives.

Dissociation of action and object naming: evidence from cortical stimulation mapping.

This cortical stimulation mapping study investigates the neural representation of action and object naming. Data from 13 neurosurgical subjects undergoing awake cortical mapping is presented. Our findings indicate clear evidence of differential disruption of noun and verb naming in the context of this naming task.
