Among HIV-seropositive IDUs receiving ART, an increasing burden of incarceration was associated with poorer adherence in a dose-dependent fashion. Our findings support improved adherence support for HIV-seropositive IDUs experiencing incarceration.

Significant health benefits were observed when minimum alcohol prices in British Columbia were increased. By contrast, adverse health outcomes were associated with an expansion of private liquor stores.

BackgroundDespite its increasing prevalence and acceptance among the general public, cannabis use continues to be viewed as an aberrant activity in many contexts. However, little is known about how stigma associated with cannabis use affects individuals who use cannabis for therapeutic purposes (CTP) and what strategies these individuals employ to manage associated stigma. The aim of this Canadian study was to describe users’ perceptions of and responses to the stigma attached to using CTP.MethodsTwenty-three individuals who were using CTP for a range of health problems took part in semi-structured interviews. Transcribed data were analyzed using an inductive approach and comparative strategies to explore participants’ perceptions of CTP and identify themes.ResultsParticipant experiences of stigma were related to negative views of cannabis as a recreational drug, the current criminal sanctions associated with cannabis use, and using cannabis in the context of stigmatizing vulnerability (related to existing illness and disability). Strategies for managing the resulting stigma of using CTP included: keeping CTP ‘undercover’; educating those who did not approve of or understand CTP use; and using cannabis responsibly.ConclusionsUnderstanding how individuals perceive and respond to stigma can inform the development of strategies aimed at reducing stigma associated with the use of CTP and thereby address barriers faced by those using this medicine.

Increases in the minimum price of alcohol in British Columbia, Canada, between 2002 and 2009 were associated with immediate and delayed decreases in alcohol-attributable mortality. By contrast, increases in the density of private liquor stores were associated with increases in alcohol-attributable mortality.

Although several factors have been found to be associated with the CFQ-R in adolescents and adults with CF, FEV1 % predicted and pulmonary exacerbations have the broadest impact on HRQoL. Further research is required to investigate the impact of age-related comorbidities, psychosocial factors, and treatment-related factors on HRQoL in adolescents/adults with cystic fibrosis.

Background and aimsThe province of British Columbia (BC) Canada has experienced a rapid increase in illicit drug overdoses and deaths during the last 4 years, with a provincial emergency declared in April 2016. These deaths have been driven primarily by the introduction of synthetic opioids into the illicit opioid supply. This study aimed to measure the combined impact of large‐scale opioid overdose interventions implemented in BC between April 2016 and December 2017 on the number of deaths averted.DesignWe expanded on the mathematical modelling methodology of our previous study to construct a Bayesian hierarchical latent Markov process model to estimate monthly overdose and overdose‐death risk, along with the impact of interventions.Setting and CasesOverdose events and overdose‐related deaths in BC from January 2012 to December 2017.InterventionsThe interventions considered were take‐home naloxone kits, overdose prevention/supervised consumption sites and opioid agonist therapyMeasurementsCounterfactual simulations were performed with the fitted model to estimate the number of death events averted for each intervention and in combination.FindingsBetween April 2016 and December 2017, BC observed 2177 overdose deaths (77% fentanyl‐detected). During the same period, an estimated 3030 (2900–3240) death events were averted by all interventions combined. In isolation, 1580 (1480–1740) were averted by take‐home naloxone, 230 (160–350) by overdose prevention services and 590 (510–720) were averted by opioid agonist therapy.ConclusionsA combined intervention approach has been effective in averting overdose deaths during British Columbia's opioid overdose crisis in the period since declaration of a public health emergency (April 2016–December 2017). However, the absolute numbers of overdose deaths have not changed.

Despite the advent of effective antiretroviral therapy (ART), HIV-seropositive injection drug users (IDU) continue to suffer from elevated levels of morbidity and mortality. Evidence is needed to identify social- and structural-level barriers to effective ART. We investigated the impact of homelessness on plasma HIV RNA response among illicit drug users initiating ART in a setting with free and universal access to HIV care. We accessed data from a long-running prospective cohort of community-recruited IDU linked to comprehensive HIV clinical monitoring and ART dispensation records. Using Cox proportional hazards with recurrent events modeling, we estimated the independent effect of homelessness on time to plasma HIV viral load suppression. Between May 1996 and September 2009, 247 antiretroviral naïve individuals initiated ART and contributed 1755 person-years of follow-up. Among these individuals, the incidence density of plasma HIV RNA suppression less than 500 copies/mm(3) was 56.7 (95% confidence interval [CI]: 46.9-66.0) per 100 person-years. In unadjusted analyses, homelessness was strongly associated with lower rates suppression (hazard ratio = 0.56, 95% CI: 0.40-0.78, p = 0.001), however, after adjustment for adherence this association was no longer significant (adjusted hazard ratio = 0.79, 95% CI: 0.56-1.11, p = 0.177). Homelessness poses a significant structural barrier to effective HIV treatment. However, since this relationship appears to be mediated by lower levels of ART adherence, interventions to improve adherence among members of this vulnerable population are needed.
