Abstract
Introduction Daily oral pre-exposure prophylaxis (PrEP) is highly safe and effective for HIV prevention, yet barriers to PrEP access and adherence persist among key populations. In Mexico, incentive-based pilot programs have been effective in improving PrEP adherence among male sex workers. Understanding the experiences of providers and program implementers is critical to integrating PrEP adherence programs as part of standard care in Mexico and similar settings. Methods We conducted 17 in-depth informational interviews with care providers and staff responsible for administering PrEP to key populations (men who have sex with men, male sex workers, transgender women) in Mexico City. Interviews explored successes and challenges surrounding current PrEP implementation, as well as adaptations that could facilitate national scale-up of PrEP programs in Mexico. Informant transcripts were analyzed using a hybrid inductive-deductive thematic analysis approach utilizing CFIR constructs for the initial codebook while allowing for inductive findings. Results Three key themes emerged from informant interviews as important for promoting PrEP programs in Mexico: 1) increasing individual PrEP access, 2) strengthening quality of care, and 3) improving organizational and structural support. Conclusions PrEP in Mexico is currently only available in a few clinics with high patient populations, and siloed HIV services, stigma, and a lack of inter-organizational collaboration remain persistent barriers to PrEP uptake. Promoting government collaboration and increasing financial support for community-based organizations is needed to expand PrEP access. Tailored, destigmatizing information about PrEP services needs to be diffused among both staff and patients to strengthen care quality.

Abstract
ABSTRACT Methamphetamine (Meth) use is a contributor to poor health outcomes among young Black American gay, bisexual, and other men who have sex with men (YB-GBMSM). Emerging research indicates that socioeconomic instability may be a salient antecedent of meth use as men may be encouraged to engage in health-eroding activities, such as survival sex, to care for themselves, and then cope with instability-related stress via use of substances. We examined the degree to which indicators of socioeconomic instability, including homelessness and food insecurity, would directly, and indirectly, predict increases in meth use, via survival sex engagement. Hypotheses were tested using mediated path analysis with data from 100 YB-GBMSM in Atlanta, Georgia. Preliminary analysis results demonstrated positive associations between engaging in survival sex, food insecurity, homelessness, and living with HIV. Findings demonstrated that homelessness and food insecurity were directly associated with increased survival sex engagement but were not directly associated with meth use. Homelessness and food insecurity were indirectly associated with increased severity of meth use, via increased engagement in survival sex. Socioeconomic instability and survival sex engagement may be important intervention targets for future meth use intervention/prevention programming. Integrating programmatic components that address homelessness and food insecurity may decrease YB-GBMSM's need to rely on survival sex to meet their needs and decrease their likelihood of using meth as a result.

Abstract
Background: Since the emergence of HIV and the AIDS pandemic, the majority of risk-reduction interventions have been centred on the use of condoms in sex workers. Methods: This qualitative study recruited 25 male migrant sex workers in London to understand their risk perception and condomless sex experiences within the context of sex work and private life. The data was collected using face-to-face interviews, analysed using thematic analysis, and the findings interpreted through the theory of planned behaviour. Results: The themes explain that condomless sex with clients occurred when participants consciously accepted to perform this service deploying a risk assessment of clients, faulty strategies, and sexual practices to reduce their risk; or when they lost control because of recreational drugs, feeling attraction to clients, were in precarious circumstances, or were victims of violence. Conversely, condomless sex with non-commercial partners occurred according to the type of relationship, with formal partners it was rationalised through emotional aspects attached to this kind of relationship, while with casual partners it was connected to sexual arousal and the use of alcohol and drugs. Conclusions: Reinforce educational interventions to deliver STI-HIV information, enhance the use of condoms, and to address specific contextual factors that facilitate condomless practice with commercial and non-commercial sexual partners.

Abstract
Incarceration among Black sexual minority men and Black transgender women (BSMM/BTW) is disproportionately high in the United States. Limited research has documented the disruptive effect of incarceration on sexual networks and sexual partnership exchange among BSMM/BTW. We estimate the influence of incarceration on selling sex and mediating pathways among 1169 BSMM/BTW enrolled in the HIV Prevention Trials Network (HPTN) 061 cohort to assess this relationship. Mediators investigated were social support, violence, illicit drug use, and distress due to experienced racism and homophobia. During the 6 months following baseline, 14% of the cohort was incarcerated, including 24% of BTW. After adjustment, recent incarceration was associated with 1.57 (95% CI 1.02, 2.42) times the risk of subsequently selling sex. The hypothesized mediators together explained 25% of the relationship, with an indirect effect risk ratio of 1.09 (95% CI 0.97, 1.24). Our results document an association and call for more research investigating mechanisms.

Abstract
INTRODUCTION Neisseria gonorrhoeae causes gonorrhoea, a globally neglected but increasing disease. This systematic review and meta-analysis reviewed the epidemiology and economic burden of gonorrhoea in Latin America and the Caribbean (LAC). METHODS We searched PubMed, EMBase, Cochrane Library, EconLIT, CINAHL, CRD, LILACS, Global Health, Global Dissertations and Theses, SciELO, Web of Science databases, countries' ministries of health, and the IHME's Global Burden of Disease databases. Studies published in the last 10 years (20 years for economic studies) were included if conducted in any LAC country, without language restrictions. The main outcome measures were incidence/prevalence, proportion of co-infections, case fatality rates, specific mortality/hospitalisation rates, direct/indirect costs, and impact of gonorrhoea on quality of life. To assess evidence quality, we used a checklist developed by the US National Heart, Lung, and Blood Institute for observational studies and trial control arms, the Cochrane Effective Practice Organization of Care Group tool for randomised controlled trials, and the CICERO checklist for economic studies. RESULTS We identified 1290 articles; 115 included epidemiological studies and one included an economic study. Ministry of health data from Argentina, Brazil, Chile, Colombia, Mexico, and Uruguay were identified. Gonorrhoea prevalence was 1.46% (95% confidence interval [CI] 1.00-2.00%) from 48 studies and 5.68% (95% CI 4.23-7.32%) from 58 studies for non-high-risk and high-risk populations, respectively. Cumulative incidence for the high-risk population was 2.05 cases per 100 persons/year. Few published studies were rated as "good" in the risk of bias assessments. Variations in the methodology of the sources and limited information found in the countries' surveillance systems hinder the comparison of data. CONCLUSION The burden of gonorrhoea in LAC is not negligible. Our results provide public health and clinical decision support to assess potential interventions to prevent gonorrhoea. TRIAL REGISTRATION The protocol is registered on PROSPERO (CRD42021253342). The study was funded by GlaxoSmithKline Biologicals SA (GSK study identifier VEO-000025).

Abstract
This scoping review assesses the use of conditional cash transfer (CCT) interventions - direct distribution of money to individuals conditional on their compliance to certain requirements - in randomised controlled trials, quasi-experimental studies and large community-based randomised trials with health-focused outcomes. Five databases were searched to identify 68 records published 2004-2021 from 25 countries (8 low- (32%), 5 lower middle- (20%), 6 upper middle- (24%) and 6 high-income (24%), according to the World Bank Categorisation (2017). Forty-six studies were unique (after excluding multiple publications on a single study). The most common outcomes assessed were infectious diseases (30%); maternal health (24%); vaccination rates (17%); and childhood developmental measures (17%). The number of participants receiving CCT in each study ranged from 47 to 5,788, with a median of 487 individuals. The number of total participants ranged from 72 to 14,000, with a median of 1,289 individuals. Fifteen percent of studies involved mobile CCT disbursement. More than a quarter of payments were greater than 50 USD (29%), and most payments were 20 USD or less (58%). Seventy-eight percent of unique full-length studies reported statistically significant CCT effects. Although CCTs remain controversial, a growing evidence base is emerging for their potential impact in specific health conditions.

Abstract
BACKGROUND Unconditional cash transfers (UCTs; provided without obligation) for reducing poverty and vulnerabilities (e.g. orphanhood, old age, or HIV infection) are a social protection intervention addressing a key social determinant of health (income) in low- and middle-income countries (LMICs). The relative effectiveness of UCTs compared with conditional cash transfers (CCTs; provided only if recipients follow prescribed behaviours, e.g. use a health service or attend school) is unknown. OBJECTIVES To assess the effects of UCTs on health services use and health outcomes in children and adults in LMICs. Secondary objectives are to assess the effects of UCTs on social determinants of health and healthcare expenditure, and to compare the effects of UCTs versus CCTs. SEARCH METHODS For this update, we searched 15 electronic academic databases, including CENTRAL, MEDLINE and EconLit, in September 2021. We also searched four electronic grey literature databases, websites of key organisations and reference lists of previous systematic reviews, key journals and included study records. SELECTION CRITERIA We included both parallel-group and cluster-randomised controlled trials (C-RCTs), quasi-RCTs, cohort studies, controlled before-and-after studies (CBAs), and interrupted time series studies of UCT interventions in children (0 to 17 years) and adults (≥ 18 years) in LMICs. Comparison groups received either no UCT, a smaller UCT or a CCT. Our primary outcomes were any health services use or health outcome. DATA COLLECTION AND ANALYSIS Two review authors independently screened potentially relevant records for inclusion, extracted data and assessed the risk of bias. We obtained missing data from study authors if feasible. For C-RCTs, we generally calculated risk ratios for dichotomous outcomes from crude frequency measures in approximately correct analyses. Meta-analyses applied the inverse variance or Mantel-Haenszel method using a random-effects model. Where meta-analysis was impossible, we synthesised results using vote counting based on effect direction. We assessed the certainty of the evidence using GRADE. MAIN RESULTS We included 34 studies (25 studies of 20 C-RCTs, six CBAs, and three cohort studies) involving 1,140,385 participants (45,538 children, 1,094,847 adults) and 50,095 households in Africa, the Americas and South-East Asia in our meta-analyses and narrative syntheses. These analysed 29 independent data sets. The 24 UCTs identified, including one basic universal income intervention, were pilot or established government programmes or research experiments. The cash value was equivalent to 1.3% to 81.9% of the annualised gross domestic product per capita. All studies compared a UCT with no UCT; three studies also compared a UCT with a CCT. Most studies carried an overall high risk of bias (i.e. often selection or performance bias, or both). Most studies were funded by national governments or international organisations, or both. Throughout the review, we use the words 'probably' to indicate moderate-certainty evidence, 'may/maybe' for low-certainty evidence, and 'uncertain' for very low-certainty evidence. Health services use We assumed greater use of any health services to be beneficial. UCTs may not have impacted the likelihood of having used any health service in the previous 1 to 12 months, when participants were followed up between 12 and 24 months into the intervention (risk ratio (RR) 1.04, 95% confidence interval (CI) 1.00 to 1.09; I2 = 2%; 5 C-RCTs, 4972 participants; low-certainty evidence). Health outcomes At one to two years, UCTs probably led to a clinically meaningful, very large reduction in the likelihood of having had any illness in the previous two weeks to three months (RR 0.79, 95% CI 0.67 to 0.92; I2 = 53%; 6 C-RCTs, 9367 participants; moderate-certainty evidence). UCTs may have increased the likelihood of having been food secure over the previous month, at 13 to 36 months into the intervention (RR 1.25, 95% CI 1.09 to 1.45; I2 = 85%; 5 C-RCTs, 2687 participants; low-certainty evidence). UCTs may have increased participants' level of dietary diversity over the previous week, when assessed with the Household Dietary Diversity Score and followed up 24 months into the intervention (mean difference (MD) 0.59 food categories, 95% CI 0.18 to 1.01; I2 = 79%; 4 C-RCTs, 9347 participants; low-certainty evidence). Despite several studies providing relevant evidence, the effects of UCTs on the likelihood of being moderately stunted and on the level of depression remain uncertain. We found no study on the effect of UCTs on mortality risk. Social determinants of health UCTs probably led to a clinically meaningful, moderate increase in the likelihood of currently attending school, when assessed at 12 to 24 months into the intervention (RR 1.06, 95% CI 1.04 to 1.09; I2 = 0%; 8 C-RCTs, 7136 participants; moderate-certainty evidence). UCTs may have reduced the likelihood of households being extremely poor, at 12 to 36 months into the intervention (RR 0.92, 95% CI 0.87 to 0.97; I2 = 63%; 6 C-RCTs, 3805 participants; low-certainty evidence). The evidence was uncertain for whether UCTs impacted livestock ownership, participation in labour, and parenting quality. Healthcare expenditure Evidence from eight cluster-RCTs on healthcare expenditure was too inconsistent to be combined in a meta-analysis, but it suggested that UCTs may have increased the amount of money spent on health care at 7 to 36 months into the intervention (low-certainty evidence). Equity, harms and comparison with CCTs The effects of UCTs on health equity (or unfair and remedial health inequalities) were very uncertain. We did not identify any harms from UCTs. Three cluster-RCTs compared UCTs versus CCTs with regard to the likelihood of having used any health services or had any illness, or the level of dietary diversity, but evidence was limited to one study per outcome and was very uncertain for all three. AUTHORS' CONCLUSIONS This body of evidence suggests that unconditional cash transfers (UCTs) may not impact a summary measure of health service use in children and adults in LMICs. However, UCTs probably or may improve some health outcomes (i.e. the likelihood of having had any illness, the likelihood of having been food secure, and the level of dietary diversity), two social determinants of health (i.e. the likelihoods of attending school and being extremely poor), and healthcare expenditure. The evidence on the relative effectiveness of UCTs and CCTs remains very uncertain.

Abstract
Pre-exposure prophylaxis (PrEP) is highly effective in preventing HIV but requires sustained adherence. Conditional economic incentives (CEIs) can improve medication-taking behaviors, yet preferences for programs that employ CEIs to increase PrEP use among male sex workers (MSWs) have not been investigated. We conducted a discrete choice experiment in Mexico City to elicit stated preferences for a CEI-based PrEP adherence program among MSWs. Respondents expressed their preferences for different program characteristics: incentive amount; incentive format; incentive type; and adherence-verification method. We used a random utility logit model to estimate the relative importance of each attribute and estimated willingness-to-pay. MSWs preferred a higher, fixed incentive, with PrEP adherence measured via hair sampling. MSWs were willing to forego up to 21% of their potential maximum CEI amount to ensure receipt of a fixed payment. MSWs are highly willing to accept a CEI-based intervention for PrEP adherence, if offered along with fixed payments.

Barriers and facilitators to pre-exposure prophylaxis uptake among male sex workers in Mexico: an application of the RE-AIM framework. BMC Public Health 2021; 21:2174. [PMID: 34837988 PMCID: PMC8626882 DOI: 10.1186/s12889-021-12167-9] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2021] [Accepted: 11/03/2021] [Indexed: 11/28/2022] Open
Abstract
Background The ImPrEP México demonstration project is the first to distribute free HIV pre-exposure prophylaxis (PrEP) to men who have sex with men (MSM) and transgender women living in Mexico. In Mexico City, MSM who are also male sex workers (MSWs) face a disproportionately high risk of HIV infection. PrEP is highly effective for HIV prevention, yet “real-life” implementation among MSWs is a challenge due to the unique adherence barriers faced by this population. Methods This study uses the RE-AIM implementation science framework to characterize the unique barriers to and facilitators of PrEP uptake among MSWs in Mexico City. We conducted 9 in-depth key informant interviews and 2 focus group discussions with MSWs across 5 clinic and community sites. Qualitative data were analyzed using inductive, open coding approaches from grounded theory. We supplemented findings from the primary qualitative analysis with quantitative indicators derived from ImPrEP program records to describe the current Reach of the ImPrEP program among MSWs in Mexico City and the potential for wider PrEP Adoption among other high-risk populations in Mexico. Results The Reach of the ImPrEP program was 10% of known HIV-negative MSWs in Mexico City. Program Reach was lowest among MSWs who were street-based sex workers, of lower socioeconomic status, migrants from other states and self-identified as heterosexual. Barriers to program Reach included limited PrEP knowledge, HIV-related stigma, and structural barriers; facilitators included in-person program recruitment, patient-centered care, and spread of information through word of mouth among MSWs. Two out of the four eligible institutions had adopted the ImPrEP protocol. Barriers to wider program Adoption included HIV- and sexual identity– related stigma, protocol limitations, and lack of a national policy for PrEP distribution; facilitators of Adoption included existing healthcare infrastructure, sensitized providers, and community support from non-governmental organizations. Conclusions Increasing the ImPrEP program’s Reach among MSWs will depend on improving PrEP education and addressing HIV-related stigma and access barriers. Future Adoption of the ImPrEP program should build on existing clinical infrastructure and community support. Creation of a national policy for PrEP distribution may improve the Reach and Adoption of PrEP among highest-risk populations in Mexico.

Abstract
BACKGROUND The World Health Organization (WHO) recommends periodic gonorrhoea prevalence assessments in the general population or proxies thereof (including pregnant women, women attending family planning clinics, military recruits, and men undergoing employment physicals for example) and in population groups at increased risk, including men-who-have-sex-with-men (MSM) and sex workers. METHOD We evaluated reported prevalence data, including estimates from proxy general population samples to reflect the WHO recommendations. We describe the outcomes from the general population country-by-country and extend previous reviews to include MSM, sex workers, and extragenital infections. RESULT AND CONCLUSION In our systematic search, 2015 titles were reviewed (January 2010-April 2019) and 174 full-text publications were included. National, population-based prevalence data were identified in only four countries (the United States of America, the United Kingdom, Peru, New Caledonia) and local population-based estimates were reported in areas within five countries (China, South Africa, Brazil, Benin, and Malawi). The remaining studies identified only reported test positivity from non-probability, proxy general population samples. Due to the diversity of the reviewed studies, detailed comparison across studies was not possible. In MSM, data were identified from 64 studies in 25 countries. Rectal infection rates were generally higher than urogenital or pharyngeal infection rates, where extragenital testing was conducted. Data on sex workers were identified from 41 studies in 23 countries; rates in female sex workers were high. Current prevalence monitoring was shown to be highly suboptimal worldwide. Serial prevalence monitoring of critical epidemiological variables, and guidelines to optimize prevalence study conduct and reporting beyond antenatal settings are recommended.

Abstract
Background Male sex workers are at high-risk for acquisition of sexually transmitted infections (STIs), including human immunodeficiency virus (HIV). We quantified incidence rates of STIs and identified their time-varying predictors among male sex workers in Mexico City. Methods From January 2012 to May 2014, male sex workers recruited from the largest HIV clinic and community sites in Mexico City were tested for chlamydia, gonorrhea, syphilis, hepatitis, and HIV at baseline, 6-months, and 12-months. Incidence rates with 95% bootstrapped confidence limits were calculated. We examined potential time-varying predictors using generalized estimating equations for a population averaged model. Results Among 227 male sex workers, median age was 24 and baseline HIV prevalence was 32%. Incidence rates (per 100 person-years) were as follows: HIV [5.23; 95% confidence interval (CI): 2.15–10.31], chlamydia (5.15; 95% CI: 2.58–9.34), gonorrhea (3.93; 95% CI: 1.88–7.83), syphilis (13.04; 95% CI: 8.24–19.94), hepatitis B (2.11; 95% CI: 0.53–4.89), hepatitis C (0.95; 95% CI: 0.00–3.16), any STI except HIV (30.99; 95% CI: 21.73–40.26), and any STI including HIV (50.08; 95% CI: 37.60–62.55). In the multivariable-adjusted model, incident STI (excluding HIV) were lower among those who reported consistently using condoms during anal and vaginal intercourse (odds ratio = 0.03, 95% CI: 0.00–0.68) compared to those who reported inconsistently using condoms during anal and vaginal intercourse. Conclusions Incidence of STIs is high among male sex workers in Mexico City. Consistent condom use is an important protective factor for STIs, and should be an important component of interventions to prevent incident infections. ![]()

Abstract
OBJECTIVES Male and transgender women sex workers (TSWs) are vulnerable for sexually transmitted infections (STIs) and human immunodeficiency virus (HIV), and substance use might be a relevant contributing factor. We assessed sociodemographic characteristics and substance use among sex workers; divided into 3 groups: Transgender women sex workers, male sex workers who have sex with men only or also with females (MSW-M), male sex workers who have sex with females only (MSW-F). METHODS A survey on substance use and sexual (risk) behavior was offered during routine STI screening at the Prostitution and Health Centre (P&G292) in Amsterdam. Bacterial STI positivity (chlamydia (including lymphogranuloma venereum), gonorrhea, and/or infectious syphilis), and substance use were compared (χ test, Fisher exact test). RESULTS From 2014 until 2015, 99 (60.4%) of 164 eligible visitors participated (n = 69 MSW-M [69.7%], n = 15 TSW [15.2%], and n = 15 MSW-F [15.2%]). Transgender women sex workers reported the highest number of sex partners in the previous 6 months (median: MSW-M 60 vs. TSW 300 vs. MSW-F 12; P < 0.001). The 3 groups did not differ in having condomless anal or oral sex. Bacterial STI positivity was 29.0% in MSW-M, 26.7% in TSW, and 13.3% in MSW-F (P = 0.56). Three new HIV infections were diagnosed, all in MSW-M, whereas 20.3% of MSW-M and 20.0% of TSW were known HIV-positive compared with none of MSW-F (P = 0.14). Illicit substance use during working time in <6 months was 40.5% among MSW-M, 40.0% among TSW, and 20.0% among MSW-F (P = 0.02). The most reported reason for substance use was: "sex work becomes physically easier." CONCLUSIONS Bacterial STI positivity and illicit substances use during work were high in all 3 sex worker groups, emphasizing the importance of combined and targeted interventions. In-depth qualitative research is needed to better understand intentions and reasons for substance use.

Abstract
Male sex workers in Kenya face a disproportionate burden of HIV and often engage in condomless sex with their commercial partners, yet little is known about how condom negotiations between male sex workers and clients take place. We conducted semi-structured interviews with 25 male sex workers and 11 male clients of male sex workers in Mombasa, Kenya, to examine barriers and facilitators to condom use and how condom use negotiation takes place in these interactions. Participants reported positive attitudes toward condom use and perceived condom use to be a health-promoting behavior. Barriers to condom use included extra-payment for condomless sex, low perceived HIV/STI risk with some sexual partners, perceived reduced pleasure associated with using condoms, alcohol use, and violence against male sex workers by clients. Future interventions should address individual- and structural-level barriers to condom use to promote effective condom use negotiation between male sex workers and male clients.

Abstract
In Mexico City, male sex workers (MSWs) are up to 126 times more likely to be living with HIV than the general public. We conducted interviews with 23 MSWs in Mexico City to examine their subjective understandings about their sexual risk behaviors and explore opportunities about HIV pre-exposure prophylaxis (PrEP) as a prevention approach in this group. Despite knowledge about sexual HIV risks, most participants reported condomless anal sex with clients. There was very little prior knowledge about PrEP, but very high interest in using a daily pill for prevention. Several participants expected an increase in condomless anal sex if taking PrEP, because of monetary incentives from clients or a perceived increase in pleasure. Additionally, seasonal sex workers expressed interest in using PrEP only during months when they were performing sex work. PrEP implementation efforts through Mexico's healthcare system should recognize the varying needs and sexual risk behaviors of MSWs.

Abstract
Stigma contributes to elevated HIV incidence among male sex workers (MSW). Social capital (i.e., resources accessed through one's social relationships) may act as a buffer between stigma and sexual risk behaviors and HIV acquisition. Using negative binomial regression, we examined the association between both sex work-related stigma and social capital with respect to number of condomless sex acts among 98 MSW living in the US Northeast. In models adjusted for sociodemographic characteristics, sex work-related stigma was associated with number of condomless sex acts with any non-paying partner (i.e., male and female) (aIRR = 1.25, p < 0.001) and male non-paying partners (aIRR = 1.27, p = 0.09) among individuals with low social capital, not among those with high social capital. Sex work-related stigma was not associated with number of condomless anal sex acts with male paying clients at any level of social capital. Future HIV prevention interventions should consider promoting social capital among MSW.

Abstract
New and innovative approaches are needed to improve the prevention, diagnosis, and treatment of HIV in low-income and middle-income countries. Several trials use conditional economic incentives (CEIs) to improve HIV outcomes. Most CEI interventions use a traditional economic theory approach, although some interventions incorporate behavioural economics, which combines traditional economics with insights from psychology. Incentive interventions that are appropriately implemented can increase HIV testing rates and voluntary male circumcision, and they can improve other HIV prevention and treatment outcomes in certain settings in the short term. More research is needed to uncover theory-based mechanisms that increase the duration of incentive effects and provide strategies for susceptible individuals, which will help to address common constraints and biases that can influence health-related decisions.

Abstract
In Latin America, men who have sex with men (MSM) remain disproportionately impacted by HIV. Pre-exposure prophylaxis (PrEP) is an effective HIV prevention tool and has been FDA approved in the United States since 2012, but no Latin American state, with the recent exception of Brazil, has implemented PrEP guidelines. We carried out a multinational online survey of MSM in Latin America (n = 22698) in 2012 to assess whether MSM at highest risk of HIV acquisition (i.e., those engaging in condomless anal sex [CAS; n = 2606] and transactional sex [n = 1488]) had higher levels of awareness of PrEP, PrEP use and interest in participating in a PrEP trial. After adjusting for demographic and psychosocial characteristics including depressive symptoms, hazardous alcohol use, childhood sexual abuse, and sexual compulsivity, transactional sex and CAS were associated with increased PrEP awareness (aOR = 1.29, 95% CI: 1.05-1.59, p < .001 and aOR = 1.22, 95% CI: 1.11-1.34, p < .001, respectively) and PrEP trial interest (aOR = 1.45, 95% CI: 1.25-1.71, p < .001 and aOR = 1.74, 95% CI: 1.57-1.95, p < .001, respectively). Findings demonstrate substantial awareness of and interest in PrEP among MSM with behavioral risk factors for HIV in Latin America, suggesting that this region is primed for PrEP implementation, which has been slow.

Abstract
Men who have sex with men (MSM) face a disproportionate burden of HIV incidence and HIV prevalence, particularly young men who have sex with men. The aim of this article was to analyze the relation between a psychological temporal perspective and HIV/sexually transmitted infection (STI) risk behaviors among male sex workers (MSWs), a potentially highly present-oriented group of MSM. A total sample of 326 MSWs were included and responded to a validated psychological scale: the Zimbardo's Time Perspective Inventory; they also reported how frequently they engaged in protective behaviors against HIV and other STI risks behaviors, including condom use with casual and regular partners, as well as prior HIV testing. We adjusted structural equation models to analyze the relation between a psychological temporal perspective and HIV/STI risk behaviors. We found that orientation toward the past was correlated with decreased condom use with casual partners (β = - 0.18; CI95% - 0.23, - 0.12). Future orientation was not associated with condom use with casual partners. Regarding condom use with regular partners, past and present orientation were related to lower likelihood of condom use (β = - 0.23; CI95% - 0.29, - 0.17; β = - 0.11; CI95% - 0.19, - 0.02), whereas future orientation increased the likelihood of condom use with regular partners (β = 0.40; CI95% 0.31, 0.50). Time orientation (past, present, or future) did not predict the probability of having an HIV test. The design of HIV/STI prevention programs among vulnerable populations, such as MSM and MSWs, should consider specific time-frame mechanisms that can importantly affect sexual risk behavior decisions.

Abstract
Objective: To describe results of HIV, sexually transmitted diseases (STI) and CD4 counts at the HIV-specialized Condesa Clinic (CC) in Mexico City. Materials and methods: Individuals who requested voluntary counseling and testing at CC were studied. We identified antibodies against HIV, syphilis, hepatitis C, and hepatitis B HBsAg. CD4 cell counts and viral load of HIV positive individuals were also obtained. Late HIV infection diagnosis was established if CD4 counts were lower than 200 cells/μL. Results: Global seroprevalence of HIV, syphilis, HBsAg, and anti HCV markers was of 20.1, 6, 1 and 1, respectively. Men displayed higher seroprevalence of infection markers than women. Among men, HIV infection was related to age and with all STI markers. Late HIV diagnosis was 31.8%. The risk of late HIV diagnosis was higher among women and it increased as age increased. Conclusions: Differences between genders regarding HIV and STIs prevalence as well as risk factors for HIV infection and late HIV diagnosis were observed.

Abstract
Over the past decade, data have identified male sex work as a potentially viable economic decision; despite this, male sex workers (MSWs) continue to be perceived as group with access to few assets and resources. Using data from a pilot skills- building intervention for MSWs in Lima, Peru, an analysis of the economic characteristics of 209 MSWs is presented. The majority reported livable incomes with median earnings of US$250 per month, 83% earning above the urban poverty line. Interestingly, non-sex work was also an important source of income, especially for the high-earning MSWs. Spending data revealed that a large portion of income went to necessities (55%), luxuries (11%), and gifts (11%), with less toward savings (5%) and studies (1%). Such data on MSWs' earnings and spending, which suggest that a lack of overall income is not the MSW's main impediment to escaping poverty, could direct future poverty alleviation and health improvement programs in this key population.

Abstract
Randomized controlled pilot evaluated effect of conditional economic incentives (CEIs) on number of sex partners, condom use, and incident sexually transmitted infections (STIs) among male sex workers in Mexico City. Incentives were contingent on testing free of new curable STIs and/or clinic attendance. We assessed outcomes for n = 227 participants at 6 and 12 months (during active phase with incentives), and then at 18 months (with incentives removed). We used intention-to-treat and inverse probability weighting for the analysis. During active phase, CEIs increased clinic visits (10-13 percentage points) and increased condom use (10-15 percentage points) for CEI groups relative to controls. The effect on condom use was not sustained once CEIs were removed. CEIs did not have an effect on number of partners or incident STIs. Conditional incentives for male sex workers can increase linkage to care and retention and reduce some HIV/STI risks such as condomless sex, while incentives are in place.

Abstract
BACKGROUND Unconditional cash transfers (UCTs; provided without obligation) for reducing poverty and vulnerabilities (e.g. orphanhood, old age or HIV infection) are a type of social protection intervention that addresses a key social determinant of health (income) in low- and middle-income countries (LMICs). The relative effectiveness of UCTs compared with conditional cash transfers (CCTs; provided so long as the recipient engages in prescribed behaviours such as using a health service or attending school) is unknown. OBJECTIVES To assess the effects of UCTs for improving health services use and health outcomes in vulnerable children and adults in LMICs. Secondary objectives are to assess the effects of UCTs on social determinants of health and healthcare expenditure and to compare to effects of UCTs versus CCTs. SEARCH METHODS We searched 17 electronic academic databases, including the Cochrane Public Health Group Specialised Register, the Cochrane Database of Systematic Reviews (the Cochrane Library 2017, Issue 5), MEDLINE and Embase, in May 2017. We also searched six electronic grey literature databases and websites of key organisations, handsearched key journals and included records, and sought expert advice. SELECTION CRITERIA We included both parallel group and cluster-randomised controlled trials (RCTs), quasi-RCTs, cohort and controlled before-and-after (CBAs) studies, and interrupted time series studies of UCT interventions in children (0 to 17 years) and adults (18 years or older) in LMICs. Comparison groups received either no UCT or a smaller UCT. Our primary outcomes were any health services use or health outcome. DATA COLLECTION AND ANALYSIS Two reviewers independently screened potentially relevant records for inclusion criteria, extracted data and assessed the risk of bias. We tried to obtain missing data from study authors if feasible. For cluster-RCTs, we generally calculated risk ratios for dichotomous outcomes from crude frequency measures in approximately correct analyses. Meta-analyses applied the inverse variance or Mantel-Haenszel method with random effects. We assessed the quality of evidence using the GRADE approach. MAIN RESULTS We included 21 studies (16 cluster-RCTs, 4 CBAs and 1 cohort study) involving 1,092,877 participants (36,068 children and 1,056,809 adults) and 31,865 households in Africa, the Americas and South-East Asia in our meta-analyses and narrative synthesis. The 17 types of UCTs we identified, including one basic universal income intervention, were pilot or established government programmes or research experiments. The cash value was equivalent to 1.3% to 53.9% of the annualised gross domestic product per capita. All studies compared a UCT with no UCT, and three studies also compared a UCT with a CCT. Most studies carried an overall high risk of bias (i.e. often selection and/or performance bias). Most studies were funded by national governments and/or international organisations.Throughout the review, we use the words 'probably' to indicate moderate-quality evidence, 'may/maybe' for low-quality evidence, and 'uncertain' for very low-quality evidence. UCTs may not have impacted the likelihood of having used any health service in the previous 1 to 12 months, when participants were followed up between 12 and 24 months into the intervention (risk ratio (RR) 1.04, 95% confidence interval (CI) 1.00 to 1.09, P = 0.07, 5 cluster-RCTs, N = 4972, I² = 2%, low-quality evidence). At one to two years, UCTs probably led to a clinically meaningful, very large reduction in the likelihood of having had any illness in the previous two weeks to three months (odds ratio (OR) 0.73, 95% CI 0.57 to 0.93, 5 cluster-RCTs, N = 8446, I² = 57%, moderate-quality evidence). Evidence from five cluster-RCTs on food security was too inconsistent to be combined in a meta-analysis, but it suggested that at 13 to 24 months' follow-up, UCTs could increase the likelihood of having been food secure over the previous month (low-quality evidence). UCTs may have increased participants' level of dietary diversity over the previous week, when assessed with the Household Dietary Diversity Score and followed up 24 months into the intervention (mean difference (MD) 0.59 food categories, 95% CI 0.18 to 1.01, 4 cluster-RCTs, N = 9347, I² = 79%, low-quality evidence). Despite several studies providing relevant evidence, the effects of UCTs on the likelihood of being moderately stunted and on the level of depression remain uncertain. No evidence was available on the effect of a UCT on the likelihood of having died. UCTs probably led to a clinically meaningful, moderate increase in the likelihood of currently attending school, when assessed at 12 to 24 months into the intervention (RR 1.06, 95% CI 1.03 to 1.09, 6 cluster-RCTs, N = 4800, I² = 0%, moderate-quality evidence). The evidence was uncertain for whether UCTs impacted livestock ownership, extreme poverty, participation in child labour, adult employment or parenting quality. Evidence from six cluster-RCTs on healthcare expenditure was too inconsistent to be combined in a meta-analysis, but it suggested that UCTs may have increased the amount of money spent on health care at 7 to 24 months into the intervention (low-quality evidence). The effects of UCTs on health equity (or unfair and remedial health inequalities) were very uncertain. We did not identify any harms from UCTs. Three cluster-RCTs compared UCTs versus CCTs with regard to the likelihood of having used any health services, the likelihood of having had any illness or the level of dietary diversity, but evidence was limited to one study per outcome and was very uncertain for all three. AUTHORS' CONCLUSIONS This body of evidence suggests that unconditional cash transfers (UCTs) may not impact a summary measure of health service use in children and adults in LMICs. However, UCTs probably or may improve some health outcomes (i.e. the likelihood of having had any illness, the likelihood of having been food secure, and the level of dietary diversity), one social determinant of health (i.e. the likelihood of attending school), and healthcare expenditure. The evidence on the relative effectiveness of UCTs and CCTs remains very uncertain.

Abstract
Barriers to retention in HIV care are detrimental to patients' progress along the HIV continuum of care. Previous literature has focused on individual, client-level barriers, and interventions to address them. In contrast, less work has examined the role of system-level barriers on HIV care outcomes. This study seeks to understand how individual and systemic barriers individually are associated with clinic appointment attendance and virologic suppression in HIV-infected patients attending the largest HIV clinic in Miami-Dade, FL. In addition, we examined the synergistic effects of these barriers as potential syndemic factors on these health outcomes. Barriers to clinic attendance were determined in a face-to-face study interview with 444 HIV-infected outpatients (187 regular attenders, 191 irregular attenders, and 66 nonattenders) identified from electronic medical records. Compared with the other attendance groups, nonattenders had higher viral loads, were less likely to be virologically suppressed, had lower CD4 counts, had higher depressive symptoms, life chaos, lower quality of life, and higher rates of food insecurity, and recent drug use. Additionally, nonattenders compared with regular attenders had lower physician relationship ratings, had lower medical information clarity and more often reported transportation as a barrier to clinic attendance. When viewed as a syndemic, compared with patients not reporting any barriers, patients with 3 or more individual-level barriers were more likely to have a detectable viral load (odds ratio = 3.60, 95% CI: 1.71 to 7.61). Our findings suggest that patients presenting to the clinic with multiple barriers should be prioritized for assistance and future interventions to improve retention in care. Interventions should address multiple individual and system-level barriers simultaneously with particular attention to addressing depressive symptoms, organizational skills, relationship with the physician, and HIV-related health education.

Abstract
Adolescents and young adults are at increased risk for HIV due to the many developmental, psychological, social, and structural transitions that converge in this period of the lifespan. In addition, adolescent deaths resulting from HIV continue to rise despite declines in other age groups. There are also young key populations (YKPs) that bear disproportionate burdens of HIV and are the most vulnerable, including young men who have sex with men (MSM), transgender youth, young people who inject drugs, and adolescent and young adult sex workers. As a society, we must do more to stop new HIV infections and untimely HIV-related deaths through both primary and secondary prevention and better management approaches. Using an interwoven prevention and treatment cascade approach, the starting point for all interventions must be HIV counselling and testing. Subsequent interventions for both HIV-negative and HIV-positive youth must be "adolescent-centred," occur within the socio-ecological context of young people and take advantage of the innovations and technologies that youth have easily incorporated into their daily lives. In order to achieve the global goals of zero infections, zero discrimination and zero deaths, a sustained focus on HIV research, policy and advocacy for YKPs must occur.
