Smoking represents an important health risk for people living with HIV (PLHIV). Low adherence to smoking cessation pharmacotherapy may limit treatment effectiveness. In this study, 158 participants recruited from three HIV care centers in New York City were randomized to receive 12-weeks of varenicline (Chantix) either alone as standard care (SC) or in combination with text message (TM) support or TM plus cell phone-delivered adherence-focused motivational and behavioral therapy (ABT). Generalized linear mixed-effect models found a significant decline in varenicline adherence from week 1–12 across treatment groups. At 12-weeks, the probability of smoking abstinence was significantly higher in SC+TM+ABT than in SC. The study demonstrates the feasibility of delivering adherence-focused interventions to PLHIV who smoke. Findings suggest intensive behavioral support is an important component of an effective smoking cessation intervention for this population, and a focus on improving adherence self-efficacy may lead to more consistent adherence and higher smoking abstinence.
Introduction: Low rates of adherence to smoking cessation pharmacotherapy may limit the effectiveness of treatment. However, few studies have examined adherence in smoking cessation trials thus, there is a limited understanding of factors that influence adherence behaviors. This brief report analyzes correlates of adherence to varenicline among people living with HIV/AIDS. Methods: Study participants were recruited from three HIV care centers in New York City and enrolled in a three-arm randomized controlled pilot study in which all subjects received varenicline. At the 1-month study visit, there were no significant differences in adherence by study condition, therefore we combined treatment arms to examine correlates of adherence (n = 127). We used pill counts to assess varenicline adherence, defined as taking at least 80% of the prescribed dose. We conducted a multivariate path analysis to assess factors proposed by the informationmotivation-behavioral skills model to predict adherence. Results: Only 56% of smokers were at least 80% adherent to varenicline at 1 month. Adherencerelated information, self-efficacy, a college degree, and non-Hispanic white race/ethnicity were associated with increased varenicline adherence. In path analysis, information and motivation were associated with increased adherence self-efficacy, and adherence self-efficacy was associated with increased adherence, but with marginal significance. These associations with adherence were no longer significant after controlling for race/ethnicity and education. Conclusions: Further exploration of the role of a modifiable correlates of adherence, such as adherencerelated information, motivation and self-efficacy is warranted. Interventions are needed that can address disparities in these and other psychosocial factors that may mediate poor medication adherence.
IntroductionThe use of anti-retroviral therapy (ART) has dramatically reduced HIV-1 associated morbidity and mortality. However, HIV-1 infected individuals have increased rates of morbidity and mortality compared to the non-HIV-1 infected population and this appears to be related to end-organ diseases collectively referred to as Serious Non-AIDS Events (SNAEs). Circulating miRNAs are reported as promising biomarkers for a number of human disease conditions including those that constitute SNAEs. Our study sought to investigate the potential of selected miRNAs in predicting mortality in HIV-1 infected ART treated individuals.Materials and MethodsA set of miRNAs was chosen based on published associations with human disease conditions that constitute SNAEs. This case: control study compared 126 cases (individuals who died whilst on therapy), and 247 matched controls (individuals who remained alive). Cases and controls were ART treated participants of two pivotal HIV-1 trials. The relative abundance of each miRNA in serum was measured, by RTqPCR. Associations with mortality (all-cause, cardiovascular and malignancy) were assessed by logistic regression analysis. Correlations between miRNAs and CD4+ T cell count, hs-CRP, IL-6 and D-dimer were also assessed.ResultsNone of the selected miRNAs was associated with all-cause, cardiovascular or malignancy mortality. The levels of three miRNAs (miRs -21, -122 and -200a) correlated with IL-6 while miR-21 also correlated with D-dimer. Additionally, the abundance of miRs -31, -150 and -223, correlated with baseline CD4+ T cell count while the same three miRNAs plus miR-145 correlated with nadir CD4+ T cell count.DiscussionNo associations with mortality were found with any circulating miRNA studied. These results cast doubt onto the effectiveness of circulating miRNA as early predictors of mortality or the major underlying diseases that contribute to mortality in participants treated for HIV-1 infection.
Background: Addressing alcohol harm in prisons can potentially reduce the risk of re-offending, and costs to society, whilst tackling health inequalities. Health savings of £4.3 m and crime savings of £100 m per year can be a result of appropriate alcohol interventions. Prison therefore offers an opportunity for the identification, response and/or referral to treatment for those male remand prisoners who are consuming alcohol above recommended levels. There is however, limited evidence for the effectiveness, optimum timing of delivery, recommended length, content, implementation and economic benefit of Alcohol Brief Interventions (ABI) in the prison setting for male remand prisoners. As part of the PRISM-A study, we aimed to explore the 'elements' of an acceptable ABI for delivery, experiences of engagement with services/health professionals about alcohol use, alongside barriers and facilitators to implementation within the prison setting for male remand prisoners. Materials and methods: Twenty-four in-depth interviews were conducted with adult male remand prisoners at one Scottish prison (n = 12) and one English prison (n = 12). A focus group at each of the prison sites was held with key stakeholders (e.g. prison nurses, prison officers, voluntary alcohol/addiction services, health service managers and commissioners). Thematic analysis techniques utilizing NViVo 10 were employed. Results: A thematic content analysis of the interviews consistently highlighted that the majority of prisoners reflected about the connection between alcohol consumption and criminal offending, particularly in relation to offenses involving physical assaults. They also expressed motivation to change their alcohol consumption. Both prisoner interviews and focus groups with stakeholders (N = 2), indicated the value of continuous follow-up support outside of the prison system and also the need to address the lack of stable social environments, which is often associated with alcohol and drug consumption. Stakeholders further identified organizational barriers to the delivery of ABI, such as limited funding and manageable workloads. Conclusions: The importance of interpersonal trust indicated that intervention delivery by external organizations and nurses were favored in comparison to intervention delivery by prison staff and peer-prisoners. A2 Does perceived risk of harm mediate the effects of a primary care alcohol screening and brief advice intervention for adolescents?
