Abstract
Worldwide, almost 40 million people are currently living with HIV-1. The implementation of cART inhibits HIV-1 replication and reduces viremia but fails to eliminate HIV-1 from latently infected cells. These cells are considered viral reservoirs from which HIV-1 rebounds if cART is interrupted. Several efforts have been made to identify these cells and their niches. There has been little success in diminishing the pool of latently infected cells, underscoring the urgency to continue efforts to fully understand how HIV-1 establishes and maintains a latent state. Reactivating HIV-1 expression in these cells using latency-reversing agents (LRAs) has been successful, but only in vitro. This review aims to provide a broad view of HIV-1 latency, highlighting Canadian contributions toward these aims. We will summarize the research efforts conducted in Canadian labs to understand the establishment of latently infected cells and how this informs curative strategies, by reviewing how HIV latency is established, which cells are latently infected, what methodologies have been developed to characterize them, how new compounds are discovered and evaluated as potential LRAs, and what clinical trials aim to reverse latency in people living with HIV (PLWH).

Abstract
Non-occupational post-exposure prophylaxis (nPEP) is recommended to reduce the likelihood of HIV infection after potential exposure. However, little is known about this practice among Chinese gay, bisexual and other men who have sex with men (GBM). GBM were enrolled from both centers for disease prevention and control (CDCs) and community health centers in six cities in China. Multivariable logistics regression was used to assess factors associated with awareness of and willingness to use nPEP. A total of 516 eligible GBM were included, 67.2% of whom were aware of nPEP, 76.0% were willing to use nPEP, and 2.3% had ever used nPEP. GBM who had college or higher education, had disclosed sexual orientation, had increased number of male sex partners in the last 6 months, and had ever tested for HIV were more likely to be aware of nPEP. Willingness to use nPEP was significantly associated with college or higher education, STI history, gay app use, and awareness of nPEP prior to study. Uptake of nPEP is still low among MSM in China. Efforts are needed to improve awareness of and access to nPEP among GBM, especially those at higher risk of HIV infection.

Abstract
We examined trends in the prevalence of post-exposure prophylaxis following sexual exposure (PEPSE) per million population (2011-2019) and the proportion of repeated PEPSE within 365 days of the first PEPSE dispensing (2011-2018) in Brazil. We also compared the prevalence of repeated PEPSE according to patient and health services characteristics in 2018. The prevalence of PEPSE increased 55.5% from 2011 to 2019. Repeated PEPSE increased 11.8%, reaching 8.4% among people with their first dispensing in 2018. The prevalence of repeated PEPSE was higher in cis men or trans women (versus cisgender women); homosexuals (versus heterosexuals); and people aged 25-29 years (versus other age groups). We also observed greater prevalence of repeated PEPSE in HIV services in populous cities or services with elevated caseloads. Our findings highlight the need for strategies to reduce repeated PEPSE and promote other HIV-prevention technologies, particularly among young adults, cisgender men, transgender women, and homosexuals.

Abstract
BACKGROUND Healthcare workers in developing countries are at particularly increased risk of infections from blood-borne pathogens because of the high prevalence of such pathogens in their communities as well as the lack of basic personal protective equipment, such as gloves, gowns and goggles. For those exposed healthcare workers, the immediate administration of antiretroviral drugs following exposure to potentially infected blood or other bodily fluids is essential in order to minimize the risk of acquiring HIV infection. This review is aimed at estimating the pooled prevalence of knowledge and uptake of post-exposure prophylaxis among healthcare providers in Africa. METHODS We accessed PubMed, Science Direct, Google Scholar, SCOPUS, African Journals Online (AJOL), Journal Storage (JSTOR) and EMBASE. The search for unpublished studies included Google and institutional repositories were also used. This meta-analysis follows the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The quality of studies was assessed using the modified Newcastle-Ottawa Scale (NOS). Meta-analysis was carried out with a random-effects method using STATA v.14 software. RESULTS Out of 654 692 studies retrieved, 37 studies from four African regions involving 6482 healthcare providers were included in this meta-analysis. The overall estimated pooled uptake and knowledge of HIV/AIDS post-exposure prophylaxis among healthcare providers in Africa using a random-effects model were 40.09% (95% CI: 30.14-50.04) and 57.67% (95% CI: 44.32-71.01) respectively, whereas the highest uptake and knowledge were 45.48% (95% CI: 24.79-66.17) and 61.37% (95% CI: 46.39-76.36) in the southern and eastern regions, respectively. CONCLUSIONS The results of this meta-analysis indicated that the knowledge and uptake of post-exposure prophylaxis, one of the best approaches to tackling HIV/AIDS transmission, are significantly low. Therefore, healthcare organizations should work on strategies to increase knowledge and uptake of post-exposure prophylaxis among healthcare providers. REGISTRATION Prospero (ID: CRD42021244003).

Abstract
We present the updated British Association for Sexual Health and HIV (BASHH) guidelines for post-exposure prophylaxis (PEP) to HIV following sexual exposures, occupational exposures and other nonoccupational exposures in the community. This serves as an update to the 2015 BASHH guideline on PEP following sexual exposures and the 2008 Expert Advisory Group on AIDS guidelines on HIV PEP. We aim to provide evidence-based guidance on best clinical practice in the provision, monitoring and support of PEP for the prevention of HIV acquisition following sexual, occupational and other nonoccupational exposures in the community. The guideline covers when to prescribe PEP, what antiretroviral agents to use and how to manage PEP. This includes (i) evidence of PEP efficacy; (ii) evidence relating to individual-level efficacy of antiretroviral therapy to prevent the sexual transmission of HIV; (iii) data on the detectable (transmissible) prevalence of HIV in specific populations; (iv) risk of HIV transmission following different types of sexual and occupational exposure; (v) baseline risk assessment; (vi) drug regimens and dosing schedules; (vii) monitoring PEP; (viii) baseline and follow-up blood-borne virus testing; (ix) the role of PEP within broader HIV prevention strategies, for example, HIV pre-exposure prophylaxis (PrEP). The guideline also covers special scenarios such as PEP in pregnancy, breastfeeding and chronic hepatitis B virus infection, and when PEP should be considered in people using HIV PrEP. The guidelines are aimed at clinical professionals directly involved in PEP provision and other stakeholders in the field. A proforma to assist PEP consultations is included. A public consultation process was undertaken prior to finalizing the recommendations.

Abstract
HIV nonoccupational postexposure prophylaxis (nPEP) has been prescribed to men who have sex with men (MSM) for decades, but the global situation of nPEP implementation among this population remains unclear. To understand nPEP awareness, uptake, and factors associated with uptake among MSM, we searched PubMed, Scopus, Embase, the Cochrane Library, and Web of Science for studies reporting nPEP implementation among MSM published before May 19, 2019. We estimated pooled rates and their 95% confidence intervals (CIs) of awareness, uptake using a random-effects model. We identified 74 studies: 3 studies (4.1%) from upper-middle-income regions and 71 (95.9%) from high-income regions. The pooled rate of nPEP awareness and uptake was 51.6% (95% CI 40.6-62.5%) and 6.0% (5.0-7.1%), respectively. Pooled uptake rate was higher in upper-middle-income regions [8.9% (7.8-10.0%)] than in high-income regions [5.8% (4.8-6.9%)]. Unprotected anal sex was the most common exposure (range: 55.0-98.6%, median: 62.9%). Pooled completion of nPEP was 86.9% (79.5-92.8%). Of 19,546 MSM prescribed nPEP, 500 HIV seroconversions (2.6%) were observed. Having risky sexual behaviors and history of sexually transmitted infections were associated with higher nPEP uptake, whereas insufficient knowledge, underestimated risk of exposure to HIV, lack of accessibility, and social stigma might hinder nPEP uptake. Awareness and uptake of nPEP among MSM worldwide are low. Further efforts are needed to combat barriers to access nPEP, including improving accessibility and reducing stigma. Seroconversions post-nPEP uptake suggest that joint prevention precautions aside from nPEP are needed for high-risk MSM. More evidence from low-income and middle-income regions is needed.

Abstract
Black men who have sex with men (BMSM) are disproportionately affected by the human immunodeficiency virus (HIV) epidemic, yet we know little about how HIV-negative BMSM of different sexual orientations access HIV prevention strategies. Identity development, minority stress, and disclosure theories suggest that for people of different sexual orientations, disclosure of sexual identity may be related to health behaviors. We performed a latent class analysis on a sample of 650 BMSM (Mage = 33.78, SD = 11.44) from Atlanta, Georgia, to explore whether sexual orientation, disclosure of sexual identity, and relationship status were related to HIV prevention strategies, including awareness of PrEP (pre-exposure prophylaxis) and PEP (post-exposure prophylaxis) and frequency of HIV testing. We found three distinct BMSM classes referred to as (1) closeted bisexuals, (2) sexual identity managers, and (3) gay, out, and open; all classes primarily engaged in casual sex. Classes differed in their awareness and access to HIV prevention strategies. The closeted bisexual class was least aware of and least likely to access HIV prevention. Findings have important implications for future research, namely the consideration of sexual identity and disclosure among BMSM. With this knowledge, we may be able to engage BMSM in HIV/sexually transmitted infection (STI) prevention services.

Abstract
AIMS: Sexualised drug taking is increasingly reported on national and international levels. We aim to review existing evidence of the relationship between recreational drug use (RDU) and sexual intercourse among men who have sex with men (MSM). METHODS: We reviewed published abstracts and full articles identified from Cochrane, MEDLINE and Embase databases from November 2010 to 2017. We included any existing studies investigating RDU in MSM and at least one of the following: high-risk sexual practices, sexually transmitted infections (STIs) or barriers to accessing specialist support. RESULTS: In total, 112 studies were included. Of them, 38 studies specifically reported the prevalence of chemsex-related drug use. Links with sexualised drug taking and high-risk sexual practices including condomless sex and group sex were reported by several studies. Recreational drug use in the sexual setting appears linked to the acquisition of STIs, including hepatitis C, syphilis and gonorrhoea. Reports of adverse mental health outcomes are increasingly described, with several studies documenting chemsex-related inpatient admission. A paucity of research addressing barriers to those accessing specialist drug support services was identified. CONCLUSION: This review demonstrates the complex interplay between recreational drug use, high-risk sexual practices and STIs. It identifies the description of adverse mental health outcomes in the chemsex setting, thus highlighting the need for a multidisciplinary approach across specialties in the management of those adversely affected. Finally, it illuminates the need for future research into perceived barriers of those who require access to support services to ensure timely and comprehensive support provision.

Abstract
This guideline is intended for use in UK Genitourinary medicine clinics and sexual health services but is likely to be of relevance in all sexual health settings, including general practice and Contraception and Sexual Health (CASH) services, where men who have sex with men (MSM) seek sexual health care or where addressing the sexual health needs of MSM may have public health benefits. For the purposes of this document, MSM includes all gay, bisexual and all other males who have sex with other males and both cis and trans men. This document does not provide guidance on the treatment of particular conditions where this is covered in other British Association for Sexual Health and HIV (BASHH) Guidelines but outlines best practice in multiple aspects of the sexual health care of MSM. Where prevention of sexually transmitted infections including HIV can be addressed as an integral part of clinical care, this is consistent with the concept of combination prevention and is included. The document is designed primarily to provide guidance on the direct clinical care of MSM but also makes reference to the design and delivery of services with the aim of supporting clinicians and commissioners in providing effective services. Methodology This document was produced in accordance with the guidance set out in the BASHH CEG's document 'Framework for guideline development and assessment' published in 2010 at http://www.bashh.org/guidelines and with reference to the Agree II instrument. Following the production of the updated framework in April 2015, the GRADE system for assessing evidence was adopted and the draft recommendations were regraded. Search strategy (see also Appendix 1) Ovid Medline 1946 to December 2014, Medline daily update, Embase 1974 to December 2014, Pubmed NeLH Guidelines Database, Cochrane library from 2000 to December 2014. Search language English only. The search for Section 3 was conducted on PubMed to December 2014. Priority was given to peer-reviewed papers published in scientific journals, although for many issues evidence includes conference abstracts listed on the Embase database. In addition, for 'Identification of problematic recreational drug and alcohol use' section and 'Sexual problems and dysfunctions in MSM' section, searches included PsycINFO. Methods Article titles and abstracts were reviewed and if relevant the full text article was obtained. Priority was given to randomised controlled trial and systematic review evidence, and recommendations made and graded on the basis of best available evidence. Piloting and feedback The first draft of the guideline was circulated to the writing group and to a small group of relevant experts, third sector partners and patient representatives who were invited to comment on the whole document and specifically on particular sections. The revised draft was reviewed by the CEG and then reviewed by the BASHH patient/public panel and posted on the BASHH website for public consultation. The final draft was piloted before publication. Guideline update The guidelines will be reviewed and revised in five years' time, 2022.

Abstract
AIMS Epidemiological research on lesbian, gay and bisexual populations raises concerns regarding self-selection and group sizes. The aim of this research was to present strategies used to overcome these challenges in a national population-based web survey of self-reported sexual orientation and living conditions-exemplified with a case of daily tobacco smoking. METHODS The sample was extracted from pre-established national web panels. Utilizing an oversampling strategy, we established a sample including 315 gay men, 217 bisexual men, 789 heterosexual men, 197 lesbian women, 405 bisexual women and 979 heterosexual women. We compared daily smoking, representing three levels of differentiation of sexual orientation for each gender. RESULTS The aggregation of all non-heterosexuals into one group yielded a higher odds ratio (OR) for non-heterosexuals being a daily smoker. The aggregation of lesbian and bisexual women indicated higher OR between this group and heterosexual women. The full differentiation yielded no differences between groups except for bisexual compared with heterosexual women. CONCLUSIONS The analyses demonstrated the advantage of differentiation of sexual orientation and gender, in this case bisexual women were the main source of group differences. We recommend an oversampling procedure, making it possible to avoid self-recruitment and to increase the transferability of findings.

Differentiating Nonoccupational Postexposure Prophylaxis Seroconverters and Non-Seroconverters in a Community-Based Clinic in Los Angeles, California. Open Forum Infect Dis 2017; 4:ofx061. [PMID: 28596981 DOI: 10.1093/ofid/ofx061] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2016] [Accepted: 04/29/2017] [Indexed: 11/14/2022] Open
Abstract
BACKGROUND Nonoccupational postexposure prophylaxis (nPEP) is a 28-day regimen of antiretroviral medications taken within 72 hours of human immunodeficiency virus (HIV) exposure to prevent HIV acquisition. Although nPEP has been recommended since 1998, few studies have analyzed the characteristics that distinguish nPEP failures (seroconverters) and successes (non-seroconverters). METHODS This retrospective study analyzed all nPEP courses prompted by sexual exposure that were prescribed at the Los Angeles LGBT Center between March 2010 and July 2014. Fisher exact tests and logistic regressions were used to determine characteristics that distinguished nPEP seroconverters from non-seroconverters. RESULTS Of the nPEP courses administered, 1744 had a follow-up visit for HIV testing within 24 weeks of exposure and 17 individuals seroconverted. Seven reported a known re-exposure, 8 self-reported only condom-protected sex subsequent to the initial exposure, and 2 reported abstinence since the exposure. In multivariable analyses, seroconverters were more likely than non-seroconverters to report methamphetamine use, incomplete medication adherence, and nPEP initiation later in the 72-hour window. CONCLUSIONS Nonoccupational postexposure prophylaxis is an important emergency tool for HIV prevention. Our findings corroborate that timing of the initial nPEP dose is an important predictor of seroconversion. Although the current study did not offer the initial nPEP dose at the beginning of the visit, use of this fast-track dosing schedule will ensure that the first dose is taken as early as possible postexposure and may lower the likelihood for seroconversion. Furthermore, we recommend systematic screening for substance use because these individuals may be well suited for pre-exposure prophylaxis given their sustained risk.

[PMID: 27412954 DOI: 10.1136/sextrans-2016-052623] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2016] [Revised: 06/06/2016] [Accepted: 06/18/2016] [Indexed: 11/04/2022] Open
Abstract
BACKGROUND/AIMS There are limited outcome data for men who have sex with men (MSM) who have received HIV postexposure prophylaxis (PEP). The objective of this service evaluation was to determine HIV incidence and repeat PEP use among MSM PEP recipients in London, UK. METHODS Retrospective electronic case-note review of all MSM who were prescribed PEP between January and April 2013 at a central London sexual health service. RESULTS 530 MSM received PEP between 1 January and 30 June 2013. Of these, 449 had more than 30 days subsequent follow-up at our service. Median age was 31 years. PEP indication was unprotected anal intercourse, 98% (receptive 88% and insertive 10%) and other, 2%. Up to 1 November 2015, total follow-up was 756 person-years. 183 users received repeat PEP. The total number of repeat PEP courses was 442. 57 MSM newly acquired HIV: the HIV incidence was 7.6 per 100 person-years. CONCLUSIONS PEP was associated with a high risk of subsequent HIV seroconversion in this cohort; this group may be appropriate candidates for pre-exposure prophylaxis.

Abstract
BACKGROUND The field of HIV prevention research has recently experienced some mixed results in efficacy trials of pre-exposure prophylaxis, vaginal microbicides, and HIV vaccines. While there have been positive trial results in some studies, in the near term, no single method will be sufficient to quell the epidemic. Improved HIV prevention methods, choices among methods, and coverage for all at-risk populations will be needed. The emergence of partially effective prevention methods that are not uniformly available raises complex ethical and scientific questions regarding the design of ongoing prevention trials. METHODS We present here an ethical analysis regarding inclusion of pre-exposure prophylaxis in an ongoing phase IIb vaccine efficacy trial, HVTN 505. This is the first large vaccine efficacy trial to address the issue of pre-exposure prophylaxis, and the decisions made by the protocol team were informed by extensive stakeholder consultations. The key ethical concerns are analyzed here, and the process of stakeholder engagement and decision-making described. DISCUSSION This discussion and analysis will be useful as current and future research teams grapple with ethical and scientific study design questions emerging with the rapidly expanding evidence base for HIV prevention.
