Introduction: Women-controlled HIV prevention technologies that overcome adherence challenges of available daily oral pre-exposure prophylaxis and give women a choice of options are urgently needed. Broadly neutralising monoclonal antibodies (bnAbs) administered passively may offer a valuable non-antiretroviral biological intervention for HIV prevention. Animal and human studies have demonstrated that bnAbs which neutralise HIV can prevent infection.

Our objective was to assess SARS-CoV-2 seroprevalence in a representative sample of pregnant people throughout Canada, across multiple time points over 2 years of the pandemic, to describe the seroprevalence and show the ability of this process to provide prevalence estimates.
Methods: This Canadian retrospective serological surveillance study used existing serological prenatal samples across 10 provinces over multiple time periods: Feb.

Background: Women represent one quarter of the population living with HIV in Canada and are an increasingly important sector of the HIV community. While some women's health issues such as cervical cancer screening and management are well addressed in HIV management guidelines, others are not. These include sexual and reproductive health factors such as contraception, pre-conception planning, and menopause.

Serosurveys estimating the prevalence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibodies in the population played a key role in characterizing SARS-CoV-2 epidemiology during the early phases of the pandemic. Existing serosurveys provide infrastructure to continue immune surveillance but must be adapted to remain relevant in the SARS-CoV-2 vaccine era.

Methods: We analyzed cross-sectional survey data from the Canadian HIV Women's Sexual and Reproductive Health Cohort Study (2017-2018). Self-identified women living with HIV were asked about sexual concerns post-HIV diagnosis and associated distress (none, mild, moderate, severe).

Introduction: Young African women bear a disproportionately high risk for HIV acquisition. HIV technologies that empower women to protect themselves are needed. Safe, potent antiretroviral agents such as tenofovir alafenamide (TAF), formulated as long-acting subdermal implants, offer an innovative solution.

Although nucleic acid amplifications tests (NAAT) are the gold standard for COVID-19 diagnostic testing, serological assays provide better population-level SARS-CoV-2 prevalence estimates. Implementing large sero-surveys present several logistical challenges within Canada due its unique geography including rural and remote communities.

Many models exist for effective North-South collaborations that are built on trust and balanced benefits. The European & Developing Countries Clinical Trials Partnership (EDCTP) model emphasises capacity development in clinical trials and product-focused implementation research.

Introduction: New HIV prevention strategies are urgently required. The discovery of broadly neutralising antibodies (bNAbs) has provided the opportunity to evaluate passive immunisation as a potential prevention strategy and facilitate vaccine development. Since 2014, several bNAbs have been isolated from a clade C-infected South African donor, CAPRISA 256.

Learning one's HIV diagnosis is the entry point to accessing life-saving antiretroviral treatment and care. Recognizing the critical role of HTS, the Joint United Nations Programme on HIV/AIDS (UNAIDS) launched the 90-90-90 targets stipulating that by 2020, 90% of people living with HIV know their status, 90% of those who know their status receive antiretroviral therapy, and 90% of those on treatment have a suppressed viral load.

Aim: To perform a systematic review examining (i) whether MC status influences women's preference for sexual activity and the reasons for this, and (ii) whether women prefer MC for their sons.
Methods: PRISMA-compliant searches were conducted of PubMed, Google Scholar, Embase, and the Cochrane Database of Systematic Reviews.
Love remains hidden in HIV research in favor of a focus on risk. Among 1424 women living with HIV in Canada, we explored (1) whether eight facets of sex and intimacy (marital status, sexual activity, physical intimacy, emotional closeness, power equity, sexual exclusivity, relationship duration, and couple HIV serostatus) may coalesce into distinct relationship types, and (2) how these relationship types may be linked to love as well as various social, psychological, and structural factors. Five latent classes were identified: no relationship (46.

However, modeling results are often not easily translated into practical policies. This paper examines the barriers and enabling factors that can allow models to better inform health decision-making.

We conducted a detailed systematic review of the scientific literature to determine the relationship between MC and risk of STIs and associated conditions in women. Database searches by "circumcision women" and "circumcision female" identified 68 relevant articles for inclusion.

Drawing on feminist theories, we measured sexual satisfaction and pleasure across five relationship types among women living with HIV in Canada. Of the 1,230 women surveyed, 38.

There has been less attention to HIV-related stigma and its associations with ART initiation and current ART use. We examined pathways from HIV-related stigma to ART initiation, current ART use, and ART adherence among women living with HIV in Canada.

Their patterns of healthcare utilisation and the suitability of healthcare services available to them are not well documented. We report on truck driver healthcare utilisation across South Africa and characterise the client population of the clinics serving them for future service development.

Focused primarily on HIV treatment, pathogenesis and prevention research in resource-limited settings, the conference attracted 369 active delegates from 34 countries, of which 22 were in Africa. Presentations on treatment optimization, acquired drug resistance, care of children and adolescents, laboratory monitoring and diagnostics, implementation challenges, HIV prevention, key populations, vaccine and cure, hepatitis C, mHealth, financing the HIV response and emerging pathogens, were accompanied by oral, mini-oral and poster presentations.
