| evidence for a sexually transmitted cofactor for aids-related kaposi's sarcoma in a cohort of homosexual men. | we examined factors associated with the subsequent development of aids-related kaposi's sarcoma in a cohort of 353 homosexual men infected with human immunodeficiency virus (hiv). cumulative incidence curves for the development of kaposi's sarcoma and opportunistic infection were stratified over a wide range of variables at enrollment, including those related to demographics, sexual behavior, illicit drug use, and medical history. we found no strong associations between any of these variables an ... | 1992 | 1591318 |
| hepatitis & hiv: prevalence of infection and changing attitudes toward infection control procedures in british columbia. | dental professionals attending the annual meeting of the college of dental surgeons of british columbia in june 1990 were involved in a survey to assess the prevalence of infection with hepatitis b, hepatitis c and human immunodeficiency viruses, the acceptance of vaccination for protection against hepatitis b virus, and the compliance with infection control guidelines. participation was voluntary and anonymous and required completion of a questionnaire and donation of a blood sample. four hundr ... | 1991 | 1747815 |
| prevalence and correlates of untreated human immunodeficiency virus type 1 infection among persons who have died in the era of modern antiretroviral therapy. | we evaluated all human immunodeficiency virus (hiv)-related deaths over the period 1 january 1995-31 december 2001 in a canadian province in which all hiv care and antiretroviral therapy are provided free of charge. persons who had received antiretroviral drugs before death were compared with those who had died without ever receiving hiv treatment, by fitting a logistic model. overall, 1239 deaths were attributed to hiv infection during the study period. of these, 406 (32.8%) occurred among pers ... | 2003 | 14551887 |
| hiv/aids: testing and risk behaviors among british columbia's rural aboriginal population. | over the last decade, there has been growing concern in the public health sector over the spread of human immunodeficiency virus (hiv) in canada's aboriginal population. however, there continues to be a general lack of hiv awareness and its risk factors in aboriginal communities. | 2006 | 17131969 |
| expanded access to highly active antiretroviral therapy: a potentially powerful strategy to curb the growth of the hiv epidemic. | we developed a mathematical model using a multiple source of infection framework to assess the potential effect of the expansion of highly active antiretroviral therapy (haart) coverage among those in medical need on the number of individuals testing newly positive for human immunodeficiency virus (hiv) and on related costs in british columbia, canada, over the next 25 years. the model was calibrated using retrospective data describing antiretroviral therapy utilization and individuals testing n ... | 2008 | 18498241 |
| an external evaluation of a peer-run outreach-based syringe exchange in vancouver, canada. | vancouver, canada has been the site of an epidemic of human immunodeficiency virus (hiv) amongst injection drug users (idu). in response, the vancouver area network of drug users (vandu) initiated a peer-run outreach-based syringe exchange programme (sep) called the alley patrol. we conducted an external evaluation of this programme, using data obtained from the vancouver injection drug users study (vidus). | 2010 | 20359877 |
| longitudinal phylogenetic surveillance identifies distinct patterns of cluster dynamics. | through the application of simple, accessible, molecular epidemiology tools, we aimed to resolve the phylogenetic relationships that best predicted patterns of cluster growth using longitudinal population level drug resistance genotype data. | 2010 | 20622676 |
| emergency department utilization among a cohort of hiv-positive injecting drug users in a canadian setting. | background: human immunodeficiency virus (hiv)-positive injection drug users (idus) are known to be at risk for multiple medical problems that may necessitate emergency department (ed) use; however, the relative contribution of hiv disease vs. injection-related complications has not been well described. objectives: we examined factors associated with ed use among a prospective cohort of hiv-positive idus in a canadian setting. methods: we enrolled hiv-positive idus into a community-recruited pro ... | 2011 | 21719229 |
