RESUMEN

BACKGROUND AIMS: The Sustained Alcohol use post-Liver Transplant (SALT) and the High-Risk Alcohol Relapse (HRAR) scores were developed to predict return to alcohol use after liver transplant (LT) for alcohol associated liver disease (ALD). METHODS: A retrospective analysis of deceased donor LT 10/2018 to 4/2022 was performed. All patients (pts) underwent careful pre-LT psychosocial evaluation. Data on alcohol use, substance abuse, prior rehabilitation, and legal issues were collected. Post-LT, all were encouraged to participate in rehabilitation programs and underwent interval phosphatidylethanol (PeTH) testing. Pts with ALD were stratified by < or > 6 month sobriety prior to listing. Those with <6 month were further stratified as acute alcoholic hepatitis (AH) by NIAAA criteria and non-AH. The primary outcome was utility of the SALT (<5 vs. ≥5) and HRAR (<3 vs. ≥3) scores to predict return to alcohol use (+PeTH) within 1 year after LT. RESULTS: Of the 365 LT, 86 had > 6 month sobriety and 85 had <6 month sobriety; 41 with AH and 44 non-AH. In those with AH, the mean time of abstinence to LT was 58 days, and 71% failed prior rehabilitation. Following LT, return to drinking was similar in the AH (24%) compared to <6M non-AH (15%) and >6M ALD (22%). Only 4% had returned to heavy drinking. The accuracy of both the SALT and HRAR scores to predict return to alcohol was low (accuracy 61-63%) with poor sensitivity (46% and 37%), specificity (67-68%), positive predictive value (22-26%) with moderate negative predictive value (NPV) (81-83%), respectively with higher NPVs (95%) in predicting return to heavy drinking. CONCLUSIONS: Both SALT and HRAR scores had good NPV in identifying patients at low risk for recidivism.

RESUMEN

BACKGROUND: Little is known about the effects of disclosure of HIV-serodiscordant relationships on clinical outcomes. We aimed to evaluate the effect of relationship disclosure on HIV viral suppression, and hypothesized that disclosure by HIV-positive and HIV-negative partners would be associated with viral suppression in the HIV-positive partner. METHODS: We conducted a Canadian national online and telephone-administered survey of HIV-positive and HIV-negative partners in serodiscordant relationships. The primary outcome was self-reported viral suppression. Multivariable analyses were undertaken using Firth logistic regression. RESULTS: We recruited 540 participants in current serodiscordant relationships (n = 228 HIV-negative; n = 312 HIV-positive). Similar proportions of HIV-positive and HIV-negative partners disclosed their relationship to healthcare professionals (82% v. 76%, p = 0.13). Among HIV-positive partners, disclosure of the relationship to healthcare professionals increased the odds of viral suppression (aOR = 4.7; CI: 2.13, 10.51) after adjusting for age, education, and relationship turmoil due to HIV. Increasing age (aOR = 1.28; 95% CI = 1.07, 1.55) and education (aOR = 2.43; 95% CI = 1.15, 5.26) were also associated with viral suppression. Among HIV-negative partners, relationship disclosure was not associated with viral suppression and HIV-negative heterosexual men were less likely to report that their HIV-positive partners were virally suppressed (aOR = 0.24; CI: 0.09, 0.61). CONCLUSIONS: Disclosure of HIV-serodiscordant status by HIV-positive participants to healthcare professionals was associated with increased odds of viral suppression. Similar effects were not evident among HIV-negative participants. Future work should explore factors that empower relationship disclosure and incorporate them into supportive services for HIV-serodiscordant relationships.

RESUMEN

BACKGROUND: With the recent shift in focus to addressing HIV risk within relationships and couple-based interventions to prevent HIV transmission, successful recruitment of individuals involved in HIV-serodiscordant relationships is crucial. This paper evaluates methods used by the Positive Plus One (PP1) study to recruit and collect data on a diverse national sample of dyads and individuals involved in current or past HIV-serodiscordant relationships, discusses the strengths and limitations of the recruitment approach, and makes recommendations to inform the interpretation of study results and the design of future studies. METHODS: PP1 used a multi-pronged approach to recruit adults involved in a current or past HIV-serodiscordant relationship in Canada from 2016 to 2018 to complete a survey and an interview. Upon survey completion, index (first recruited) partners were invited to recruit their primary current HIV-serodiscordant partner. We investigated participant enrollment by recruitment source, participant-, relationship-, and dyad-level sociodemographic characteristics, missing data, and correlates of participation for individuals recruited by their partners. RESULTS: We recruited 613 participants (355 HIV-positive; 258 HIV-negative) across 10 Canadian provinces, including 153 complete dyads and 307 individuals who participated alone, and representing 460 HIV-serodiscordant relationships. Among those in current relationships, HIV-positive participants were more likely than HIV-negative participants to learn of the study through an ASO staff member (36% v. 20%, p < 0.001), ASO listserv/newsletter (12% v. 5%, p = 0.007), or physician/staff at a clinic (20% v. 11%, p = 0.006). HIV-negative participants involved in current relationships were more likely than HIV-positive participants to learn of the study through their partner (46% v. 8%, p < 0.001). Seventy-eight percent of index participants invited their primary HIV-serodiscordant partner to participate, and 40% were successful. Successful recruitment of primary partners was associated with longer relationship duration, higher relationship satisfaction, and a virally suppressed HIV-positive partner. CONCLUSIONS: Our findings provide important new information on and support the use of a multi-pronged approach to recruit HIV-positive and HIV-negative individuals involved in HIV-serodiscordant relationships in Canada. More creative strategies are needed to help index partners recruit their partner in relationships with lower satisfaction and shorter duration and further minimize the risk of "happy couple" bias.

RESUMEN

Positive Plus One is a mixed-methods study of long-term mixed HIV-serostatus relationships in Canada (2016-19). Qualitative interviews with 51 participants (10 women, 41 men, including 27 HIV-positive and 24 HIV-negative partners) were analyzed using inductive thematic analysis to examine notions of relationship resilience in the context of emerging HIV social campaigns. Relationship resilience meant finding ways to build and enact life as a normal couple, that is, a couple not noticeably affected by HIV, linked to the partner with HIV maintaining viral suppression and achieving "undetectable = untransmittable" (U = U). Regardless of serostatus, participants with material resources, social networks, and specialized care were better able to construct resilience for HIV-related challenges within their relationships. Compared to heterosexual couples and those facing socioeconomic adversity, gay and bisexual couples were easier able to disclose, and access capital, networks and resources supporting resilience. We conclude that important pathways of constructing, shaping, and maintaining resilience were influenced by the timing of HIV diagnosis in the relationship, access to HIV-related information and services, disclosure, stigma and social acceptance.

RESUMEN

Positive Plus One is the first large-scale mixed methods study of mixed HIV serostatus couples in Canada. We aimed to understand how biomedicalization i.e., a social process of commodification and expansion of the jurisdiction of medicine over health, influenced the everyday relationships of these couples. We completed 51 semi-structured interviews among a purposive sample of HIV-positive (n = 27) and HIV-negative (n = 24) partners in current or past mixed-serostatus relationships. Participants were recruited after completing an online survey where they consented to be re-contacted for qualitative interviews. Participants represented a diversity of sexual orientations, gender identities, and other sociodemographic characteristics. Drawing on inductive thematic analysis to identify patterns within couples, across serostatus and sexual orientations, we argue that everyday lives of mixed-serostatus couples were shaped by biomedical knowledge and enacted through routine adherence to obtain and maintain viral load undetectability. Our findings illustrated the importance of learning biomedical knowledge for mixed-serostatus couples in this study, the empowering influence of undetectable = untransmittable (UU) discourse, and its role in rendering HIV mundane through routine ART adherence. We introduce the concept of 'dual pharmaceutical citizenship' to underscore a process by which particular biopolitical and biomedical expectations are fulfilled in mixed-serostatus relationships. These findings have implications for people who do not readily accept or have access to biomedical knowledge, particularly when treatment-as-prevention frames a "right" and "wrong" approach to HIV management. Future studies should focus on couples where at least one partner does not readily accept or have access to biomedical knowledge.

RESUMEN

As people living with HIV are living longer lives, they have a correspondingly greater opportunity to enjoy long-term romantic and sexual partnerships, including with persons who do not live with HIV ("serodiscordant" relationships). In these dyads, asymmetries may emerge in access to social resources between partners. In this paper we examined how serodiscordant couples access informal (interpersonal, such as family and friends) and formal (practitioner, such as doctor or social worker) social resources for health. We recruited 540 participants in current serodiscordant relationships, working with 150 AIDS service organizations and HIV clinics across Canada from 2016 to 2018. Our findings demonstrate that partners with HIV have greater access to formal resources than their partners (through health care professionals, therapists/counselors/support workers), while both persons have similar access to resources through informal social relationships (family and friends). Furthermore, the findings indicated that HIV positive partners accessed more varied forms of support through formal ties, compared to HIV negative persons. We offer recommendations for changes to how HIV-negative partners in a serodiscordant relationship are served and cared for, and particularly, the importance of moving toward dyad-focused policies and practices.

RESUMEN

Rates of HIV (human immunodeficiency virus) and sexual-risk behaviour for those aged 50 and over in the United States are highest and increasing in Florida, where many Canadian "snowbirds" winter. This pilot study examined the sexual-risk behaviour and predictors of HIV testing in a convenience sample of Canadian snowbirds who winter in Florida (n = 265). Multivariate logistic regression analyses revealed that the odds of testing were increased for the unmarried, those aged 50-64, those who had talked to a doctor about sexual-risk behaviour since age 50, and those who agreed that sex was important in their lives. Dating males were more likely to test than non-dating males. Dating females were not more likely to test than non-dating females; and males who dated were 13.6 times more likely to test than females who dated. Further research will improve understanding of Canadian snowbirds' sexual interactions and HIV-testing behaviour.

RESUMEN

OBJECTIVE: To examine factors that affect the utilization of HIV testing and counseling (HTC) services among heterosexual populations in Canada and the U.K. METHODS: We conducted an integrated review of published and unpublished literature (1996-September 2010) using Scopus, OVID-EMBASE, CSA illumina, CINHAL, PROQuest, Web of Science, and Google. RESULTS: Twenty-seven studies met the inclusion criteria. We identified and categorized the key factors into three broad categories depending on their source. Personal-related factors included socio-demographic characteristics, risk perception, illness, HIV-related stigma, level of HIV and testing knowledge, and culture. Provider-related factors included provider-recommended HIV testing, provision of culturally and linguistically appropriate services, and doctor-patient relationship. System-related factors included integrating HIV testing with other health care services, anonymity of testing services, suitability of testing venues, technical aspects of HIV testing, and funding for immigrant health services. CONCLUSION: The findings from our review indicate that HTC behaviors of heterosexuals in the Canada and the U.K. are likely influenced by several unchangeable (socio-demographic characteristics) and amenable factors. There is need to step-up research to confirm whether these associations are causal using stronger research designs. PRACTICAL IMPLICATION: We have made several recommendations that could be used to improve existing services in Canada.

RESUMEN

BACKGROUND: Interracial relationships in Canada have increased over the years. However, little research has focused on comparing STI/HIV risk and condom use between those in intra- and interracial relationships, specifically among Middle Eastern-Canadians. METHODS: A web-based survey was administered to Middle Eastern-Canadians. Logistic regression analysis was used to assess factors associated with consistent condom use. Analyses were stratified by partner's race (Middle Eastern or non-Middle Eastern). RESULTS: The analysis sub-sample consisted of 92 participants. Factors associated with consistent condom use varied between the stratified groups. Among those with Middle Eastern partners, attitude towards marriage and the family and control in the relationship were associated with condom use. Among participants with non-Middle Eastern partners, acculturation and HIV knowledge were found to be associated with condom use. DISCUSSION: Factors associated with condom use varied between Middle Eastern-Canadians in intra- and interracial relationships. These differences illustrate the need for tailored interventions aimed at increasing condom use among this racial group.

RESUMEN

HIV and AIDS remain highly stigmatised. Modified directly observed therapy (m-DOT) supports antiretroviral treatment (ART) adherence but little is known about its association with perceived stigma in resource-constrained settings. In 2003, 234 HIV-infected adults enrolled in a two-arm randomised trial comparing a health centre-based m-DOT strategy with standard self-administration of ART. Data on perceived stigma were collected using Berger's HIV stigma scale prior to starting ART and after 12 months. This was a secondary analysis to examine whether perceived stigma was related to treatment delivery. Perceived stigma scores declined after 12 months of treatment from a mean of 44.9 (sd=7.6) to a mean of 41.4 (sd=7.7), (t=6.14, P<0.001). No differences were found between the mean scores of participants in both study arms. Also, no difference in scores was detected using GLM, controlling for socio-demographic characteristics and baseline scores. Findings indicate that a well managed clinic-based m-DOT does not increase perceived HIV-related stigma.
