Substance Use, Depression and Sociodemographic Determinants of HIV Sexual Risk Behavior in Outpatient Substance Abuse Treatment Patients

Effectiveness of a Cognitive Behavioral Randomized Controlled Trial for People Living with HIV Who are Heavy Drinkers: The Holistic Health Recovery Program (HHRP) Trial in Miami

This study evaluates the impact of an intervention targeting high-risk behaviors among diverse, alcohol-using adults living with HIV (N = 267) from 2009 to 2013 in Miami, FL. The intervention took place in a group setting for eight sessions over 4 weeks and was compared to a didactic health promotion group. Assessments were conducted pre-intervention, post-intervention, and at 3, 6, and 12 months follow-up. Intervention participants (48% of sample) evidenced greater knowledge about HIV, more condom self-efficacy, and greater intentions to use condoms after participation. This was particularly noteworthy because associations among knowledge about HIV, more condom self-efficacy, and greater intentions to use condoms were negatively associated with intervention status at baseline. Participants also reported fewer heavy drinking days after participating in the intervention than those in the control group. Greater HIV knowledge, more condom self-efficacy and intentions to use condoms predicted more condom assertiveness; greater intentions to use condoms predicted fewer unprotected sexual behaviors. These findings underscore the importance of taking a comprehensive, multi-systemic approach to address risky behaviors in high-risk, diverse populations.

Longitudinal predictors of male sexual partner risk among Black and Latina women in their late thirties: ethnic/racial identity commitment as a protective factor

This study aimed to investigate predictors of male sexual partner risk among Latinas and Black women in their late thirties. We used multiple regression analysis to examine factors associated with male sexual partner risk among 296 women who participated in two waves of the Harlem Longitudinal Development Study (New York, 2011-2013 and 2014-2016). Women who experienced childhood sexual abuse had higher risk partners than those who did not [b = 0.16, 95% confidence interval (CI) = 0.06, 0.28]. Earlier marijuana use was a risk factor for partner risk in the late thirties (b = 0.12, 95% CI = 0.04, 0.27). Higher levels of ethnic/racial identity commitment mitigated this risk (b = - 0.15, 95% CI = - 0.26, - 0.04). Ethnic/racial identity commitment can be protective against male sexual partner risk among Latina and Black women who use marijuana. Further research should explore the protective role of different dimensions of ethnic/racial identity against sexually transmitted infections, including HIV.

HIV, schizophrenia, and all-cause mortality: A population-based cohort study of individuals accessing universal medical care from 1998 to 2012 in British Columbia, Canada

Schizophrenia is a severe mental illness with important implications for morbidity and mortality. This population-based cohort study examined the impact of schizophrenia diagnoses on all-cause mortality among a sample of people living with HIV (PLHIV) and a 10% random sample of individuals living without HIV (HIV-) in British Columbia (BC), through a data linkage between the BC Centre for Excellence in HIV/AIDS and Population Data BC's data holdings. Schizophrenia diagnoses were identified via International Classification of Diseases version 9 and version 10 codes. Age- and sex-adjusted all-cause mortality rates from January 1st, 1998 to December 31st, 2012 were calculated. Multivariable logistic models assessed (1) HIV status and mortality among individuals diagnosed with schizophrenia, (2) schizophrenia diagnosis and mortality among PLHIV, and (3) correlates of mortality among PLHIV concurrently diagnosed with schizophrenia (HIV+/SZO+). From 1998 to 2012, 6.3% of those with HIV had a schizophrenia diagnosis, compared to 1.1% of those without HIV. While significant declines in mortality rates were observed throughout the study period, mortality rates were highest among HIV+/SZO+. After adjustment for substance use disorder and age at baseline, HIV+/SZO+ had a 2.64 times greater odds of mortality (95% confidence interval [CI] = 2.14-3.25) compared to HIV-/SZO+. For PLHIV, a schizophrenia diagnosis was not associated with mortality after controlling for potential confounders (adjusted odds ratio [aOR] = 0.90, 95%CI = 0.74-1.09). Among HIV+/SZO+, age, history of injection drug use, ever having an AIDS-defining illness, and never being on anti-psychotic medication or accessing psychiatric services were associated with mortality. Efforts should be made to identify and link to care individuals disproportionately affected by schizophrenia and excess mortality, including those living with HIV.

Associations of Drug Use, Violence, and Depressive Symptoms with Sexual Risk Behaviors Among Women with Alcohol Misuse

BACKGROUND

Alcohol misuse is associated with increased human immunodeficiency virus sexual risk behaviors by women. Drug use, intimate partner violence (IPV), and depressive symptoms frequently co-occur, are well-recognized alcohol misuse comorbidities, and may interact to increase risk behaviors. Using a syndemic framework we examined associations between drug use, IPV, and depressive symptoms and sexual risk behaviors by 400 women with alcohol misuse attending an urban sexually transmitted infections clinic.

METHODS

Participants completed computer-assisted interviews querying drug use, IPV, and depressive symptoms and sexual risk behavior outcomes-unprotected sex under the influence of alcohol, sex for drugs/money, and number of lifetime sexual partners. We used multivariable analysis to estimate prevalence ratios (PR) for independent and joint associations between drug use, IPV, and depressive symptoms and our outcomes. To investigate synergy between risk factors we calculated the relative excess prevalence owing to interaction for all variable combinations.

RESULTS

In multivariable analysis, drug use, IPV, and depressive symptoms alone and in combination were associated with higher prevalence/count of risk behaviors compared with women with alcohol misuse alone. The greatest prevalence/count occurred when all three were present (unprotected sex under the influence of alcohol [PR, 2.6; 95% confidence interval, 1.3-4.9]), sex for money or drugs [PR, 2.6; 95% confidence interval, 1.7-4.2], and number of lifetime partners [PR, 3.2; 95% confidence interval, 1.9-5.2]). Drug use, IPV, and depressive symptoms did not interact synergistically to increase sexual risk behavior prevalence.

CONCLUSIONS

A higher prevalence of sexual risk behaviors by women with alcohol misuse combined with drug use, IPV, and depressive symptoms supports the need for alcohol interventions addressing these additional comorbidities.

Preoperative screening for illicit drug use in patients undergoing emergency surgery: A prospective observational study

Knowledge of illicit drug users (IDUs) is important because of the comorbidity related to drug use. In this prospective, observational study, we screened 1007 patients undergoing emergency surgery and found that 75 of them (7.5%) were IDUs The results of preoperative screening showed that the rates of HIV and syphilis infection were significantly higher in IDUs (HIV (+) 2.6%, syphilis (+) 10.7%) than in non-IDUs (HIV (+) 0, syphilis (+) 0.5%). Intraoperative consumption of remifentanil (IDUs: 1.85 ± 1.30 vs. non-IDUs: 1.31 ± 0.86, p = 0.009), midazolam (IDUs: 4.82 ± 1.52 vs. non-IDUs: 4.15 ± 1.81, p = 0.002), and atracurium (IDUs: 31.5 ± 15.1 vs. non-IDUs: 25.5 ± 11.9, p = 0.006) and the proportion of patients requiring postoperative fentanyl (IDUs: 15 (20.0%) vs. non-IDUs: 95 (1.2%), p = 0.031) were significantly increased in IDUs compared to non-IDUs. Postoperative complications were observed in 22.7% (17/75) of patients who were IDUs, which was significantly increased when compared with non-IDUs (6.0%, 56/932, p < 0.001). The mortality rate within 30 days after surgery was similar between the two groups. These findings suggested that the IDUs were associated with increased rates of HIV and syphilis infection; greater consumption of intraoperative opioids, sedatives, and muscle relaxants; increased postoperative complications and a similar mortality rate within 30 days after surgery when compared with non-IDUs.

Intravenous heroin use in Haiphong, Vietnam: Need for comprehensive care including methamphetamine use-related interventions

BACKGROUND

The aim of this study was to describe patterns among people who inject drugs (PWID), risk-related behaviours and access to methadone treatment, in order to design a large-scale intervention aiming to end the HIV epidemic in Haiphong, Vietnam.

METHODS

A respondent-driven sampling (RDS) survey was first conducted to identify profiles of drug use and HIV risk-related behaviour among PWID. A sample of PWID was then included in a one-year cohort study to describe access to methadone treatment and associated factors.

RESULTS

Among the 603 patients enrolled in the RDS survey, 10% were female, all were injecting heroin and 24% were using methamphetamine, including 3 (0.5%) through injection. Different profiles of risk-related behaviours were identified, including one entailing high-risk sexual behaviour (n=37) and another involving drug-related high-risk practices (n=22). High-risk sexual activity was related to binge drinking and methamphetamine use. Among subjects with low sexual risk, sexual intercourse with a main partner with unknown serostatus was often unprotected. Among the 250 PWID included in the cohort, 55.2% initiated methadone treatment during the follow-up (versus 4.4% at RDS); methamphetamine use significantly increased. The factors associated with not being treated with methadone after 52 weeks were fewer injections per month and being a methamphetamine user at RDS.

CONCLUSION

Heroin is still the main drug injected in Haiphong. Methamphetamine use is increasing markedly and is associated with delay in methadone initiation. Drug-related risks are low but sexual risk behaviours are still present. Comprehensive approaches are needed in the short term.
