Abstract
Sexually Transmitted Infections (STIs) are a critical global health concern, with low- and middle-income countries carrying the highest burden. The development of rapid point-of-care STI tests has enabled screening in settings without laboratory access. Yet, high-need settings face unique challenges that may influence the implementation and uptake of STI screening. This piece discusses lessons learned from the implementation of STI screening in a rural, low-resource setting in Chiapas, Mexico. Despite minimal privacy and a low staff-to-patient ratio, a streamlined approach was developed to destigmatize and maximize STI screening. The clinic team developed strategies through practice, including incorporating screening into triage procedures and offering screening to family members. This protocol led to an average screening rate of 37% within three months and acceptance of screening by family units. It was observed that access to treatment was necessary to alleviate patient hesitation to screening due to fears of a positive result. As STI screening increases globally, healthcare systems must develop robust access to treatment to effectively prevent and treat STIs worldwide.

Abstract
The level of knowledge that people living with human immunodeficiency virus (HIV) have about their disease can impact their adherence to treatment. The aim of this study was to develop a tool to assess the knowledge about HIV among people receiving treatment at a specialized clinic in Mexico City. To establish content validity, expert judges were invited to conceptualize the tool and propose items for the defined dimensions. A total of 490 individuals living with HIV completed the 91-item questionnaire, with 82.2% being male and a mean age of 36.1 years. We conducted an exploratory factor analysis, resulting in a reduced questionnaire of 45 questions. A three-factor solution explained 36.2% of the variance in HIV knowledge. The total scale had a reliability coefficient of 0.937, and each subscale had reliabilities of 0.828, 0.856 and 0.859. Lower educational level (F(336) = 8.488, p < 0.001) and female gender (t(399) = 2.003, p = 0.046) were associated with lower scores on the HIV knowledge questionnaire. This tool appears suitable for measuring HIV knowledge in people living with HIV, although future studies are required to confirm its structure and reduce its extension.

Abstract
The Joint United Nations Program on human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) (Joint United Nations Program on HIV/AIDS, UNAIDS) has recommended 90-90-90 goals to increase the number of patients who are aware of their status, on antiretroviral therapy, and have undetectable viral loads. Mexico City has made several achievements to aid in prevention, early diagnosis, and treatment; however, the incidence of HIV has not decreased over the past decade. This article reviews global initiatives that were successful in achieving some or all these metrics and provide a road map for Mexico to reach the desired goals.

Sexual Behavior Patterns of Black Young Adults in Georgia: Results from a Latent Class Analysis. J Racial Ethn Health Disparities 2023; 10:271-281.

Abstract
The state of Georgia ranks first in the rate of new diagnosis of HIV/AIDS, yet studies focused on understanding the drivers of this epidemic in the most at-risk groups outside the Atlanta Metropolitan Statistical Area (MSA) remain sparse. Among the many consequences of this is the inability to effectively design tailored intervention programs that appropriately address the reduction of HIV/AIDS and other STDS in the state. Reducing disparities in HIV/AIDS remains an important goal in the National HIV/AIDS Strategy. Given the disproportionate burden of the HIV/AIDS epidemic among Blacks in the state of Georgia, there is a significant need to focus research attention on the sexual behavior of young people that predisposes them to increased risk of HIV/AIDS infection. The current study used latent class analysis (LCA) to examine the sexual behavior patterns of Black young adults living in Georgia. LCA results revealed a two-class fit with distinct sexual behavior patterns. Gender and educational attainment emerged as significant predictors of class membership. Our findings contribute to the vast literature showing that sexual behavior patterns of Black young adults are not homogenous, and underscore the significance of socio-demographic and contextual factors in shaping sexual risk behavior.

Abstract
OBJECTIVES To compare women with men presenting with HIV to a public health HIV clinic, to identify the special characteristics and health care needs of women living with HIV in the Barwon South West region in Victoria. METHODS A retrospective cohort study of 35 women and 135 men living with HIV who attended the clinic between 2009 and 2020. Gender differences were assessed using nonparametric analyses. RESULTS The women were diagnosed with HIV younger than the men (mean 29.5 years vs. 36.7 years) and more were born in Africa (28.6% vs. 5.2%). More men than women presented with sexually transmittable infections (38.5% vs. 14.3%) at the time of diagnosis, and were diagnosed through a sexual health screen (37% vs. 17%). The proportions of men and women who used alcohol and other drugs (recent to their diagnosis) were similar (68.1% vs. 48.6%), and there was no difference in proportions presenting with AIDS-defining illnesses (p = 0.425), or CD4 cell count (advanced: ≤200 cells, relatively well: ≥201 cells, p = 0.241), but the women had a lower viral load (p < 0.001). CONCLUSIONS In this study of 170 people living with HIV, nearly one-half of the men with known HIV history were diagnosed through sexual health screens, but women's HIV was mostly detected through targeted screening. Results highlight gender disparity in access to sexual health screening and assessment, including low awareness of sexual health risks for women, and endorse the view that HIV is a heterosexual sexually transmittable infection in women.

Abstract
Este artículo presenta un ejercicio acerca de la potencia heurística de la teoría feminista de la interseccionalidad para enriquecer la aproximación de condicionantes sociales en salud (css), en las posibilidades de acceso de un conjunto de mujeres con vih/sida a la atención especializada en el estado de Chiapas. Se realizó una encuesta con una muestra representativa de mujeres cisgénero en tratamiento antirretroviral, provenientes de localidades indígenas y rurales, con el fin de explorar cuatro indicadores de tales css: inseguridad alimentaria, violencia de género, sobrecarga del trabajo de cuidados e inaccesibilidad geográfica de las clínicas. El componente cualitativo se propuso conocer la experiencia subjetiva en relación con tales condicionantes, por medio de 32 entrevistas individuales. Destacan ciertos circuitos de retroalimentación en los que la precariedad económica y subjetiva, la violencia, la violación de derechos y la exclusión se intensifican ante el estigma social del diagnóstico de vih/sida y producen una serie de malestares en las mujeres. Retomamos la estrategia teórico-metodológica sobre la geografía de la interseccionalidad (Rodó-Zárate, 2021) y su herramienta de los Relief Maps para analizar tales malestares como indicadores de desigualdades sociales, mismas que a su vez se concretan en lugares específicos, y que colocan a las personas en posiciones diversas de opresión y privilegio. Identificamos un conjunto de malestares sistémicos/sistemáticos preexistentes e incrementados por el estigma del vih/sida, al tiempo que las clínicas especializadas se viven como un lugar de alivio donde el estigma se ve diluido.

Abstract
Evolutionary analyses of viral sequences can provide insights into transmission dynamics, which in turn can optimize prevention interventions. Here, we characterized the dynamics of HIV transmission within the Mexico City metropolitan area. HIV pol sequences from persons recently diagnosed at the largest HIV clinic in Mexico City (between 2016 and 2021) were annotated with demographic/geographic metadata. A multistep phylogenetic approach was applied to identify putative transmission clades. A data set of publicly available sequences was used to assess international introductions. Clades were analyzed with a discrete phylogeographic model to evaluate the timing and intensity of HIV introductions and transmission dynamics among municipalities in the region. A total of 6,802 sequences across 96 municipalities (5,192 from Mexico City and 1,610 from the neighboring State of Mexico) were included (93.6% cisgender men, 5.0% cisgender women, and 1.3% transgender women); 3,971 of these sequences formed 1,206 clusters, involving 78 municipalities, including 89 clusters of ≥10 sequences. Discrete phylogeographic analysis revealed (i) 1,032 viral introductions into the region, over one-half of which were from the United States, and (ii) 354 migration events between municipalities with high support (adjusted Bayes factor of ≥3). The most frequent viral migrations occurred between northern municipalities within Mexico City, i.e., Cuauhtémoc to Iztapalapa (5.2% of events), Iztapalapa to Gustavo A. Madero (5.4%), and Gustavo A. Madero to Cuauhtémoc (6.5%). Our analysis illustrates the complexity of HIV transmission within the Mexico City metropolitan area but also identifies a spatially active transmission area involving a few municipalities in the north of the city, where targeted interventions could have a more pronounced effect on the entire regional epidemic. IMPORTANCE Phylogeographic investigation of the Mexico City HIV epidemic illustrates the complexity of HIV transmission in the region. An active transmission area involving a few municipalities in the north of the city, with transmission links throughout the region, is identified and could be a location where targeted interventions could have a more pronounced effect on the entire regional epidemic, compared with those dispersed in other manners.

Abstract
Treatment as Prevention is a key biopolitical intervention on the HIV epidemic but relies on individual adherence to antiretroviral treatment in order to have an effect on the population as a whole. Informed by a discussion of biopower, this paper analyses the complex relationships between discourses of competent authorities and modes of subjectification through a qualitative analysis of findings from 5 years of fieldwork associated with the action-research project Yantzin: Women HIV Peer Advisors in Mexico. It looks at the production of subjects of adherence, whereby peer advisors emerge as key agents at the interface between scientific and experiential knowledge. Contradictorily, the desire to live becomes feasible only by engaging with these biopolitical interventions. We discuss how peer advisors twist these technologies in such a way that they provide not only operations of power but also courses of action for desire. Through embodied mediation strategies that critique obedience to medical prescription and translate scientific information into bodily and emotionally shared experiences, peer advisors' work goes beyond the behavioural rationality of biomedical models offering embodied proof for other women that, even when living with HIV, a project of happiness is possible.

Abstract
We describe associations of pretreatment drug resistance (PDR) with clinical outcomes such as remaining in care, loss to follow-up (LTFU), viral suppression, and death in Mexico, in real-life clinical settings. We analyzed clinical outcomes after a two-year follow up period in participants of a large 2017–2018 nationally representative PDR survey cross-referenced with information of the national ministry of health HIV database. Participants were stratified according to prior ART exposure and presence of efavirenz/nevirapine PDR. Using a Fine-Gray model, we evaluated virological suppression among resistant patients, in a context of competing risk with lost to follow-up and death. A total of 1823 participants were followed-up by a median of 1.88 years (Interquartile Range (IQR): 1.59–2.02): 20 (1%) were classified as experienced + resistant; 165 (9%) naïve + resistant; 211 (11%) experienced + non-resistant; and 1427 (78%) as naïve + non-resistant. Being ART-experienced was associated with a lower probability of remaining in care (adjusted Hazard Ratio(aHR) = 0.68, 0.53–0.86, for the non-resistant group and aHR = 0.37, 0.17–0.84, for the resistant group, compared to the naïve + non-resistant group). Heterosexual cisgender women compared to men who have sex with men [MSM], had a lower viral suppression (aHR = 0.84, 0.70–1.01, p = 0.06) ART-experienced persons with NNRTI-PDR showed the worst clinical outcomes. This group was enriched with women and persons with lower education and unemployed, which suggests higher levels of social vulnerability.

Abstract
INTRODUCTION Molecular surveillance systems could provide public health benefits to focus strategies to improve the HIV care continuum. Here, we infer the HIV genetic network of Mexico City in 2020, and identify actively growing clusters that could represent relevant targets for intervention. METHODS All new diagnoses, referrals from other institutions, as well as persons returning to care, enrolling at the largest HIV clinic in Mexico City were invited to participate in the study. The network was inferred from HIV pol sequences, using pairwise genetic distance methods, with a locally hosted, secure version of the HIV-TRACE tool: Seguro HIV-TRACE. Socio-demographic, clinical and behavioural metadata were overlaid across the network to design focused prevention interventions. RESULTS A total of 3168 HIV sequences from unique individuals were included. One thousand and one-hundred and fifty (36%) sequences formed 1361 links within 386 transmission clusters in the network. Cluster size varied from 2 to 14 (63% were dyads). After adjustment for covariates, lower age (adjusted odds ratio [aOR]: 0.37, p<0.001; >34 vs. <24 years), being a man who has sex with men (MSM) (aOR: 2.47, p = 0.004; MSM vs. cisgender women), having higher viral load (aOR: 1.28, p<0.001) and higher CD4+ T cell count (aOR: 1.80, p<0.001; ≥500 vs. <200 cells/mm3 ) remained associated with higher odds of clustering. Compared to MSM, cisgender women and heterosexual men had significantly lower education (none or any elementary: 59.1% and 54.2% vs. 16.6%, p<0.001) and socio-economic status (low income: 36.4% and 29.0% vs. 18.6%, p = 0.03) than MSM. We identified 10 (2.6%) clusters with constant growth, for prioritized intervention, that included intersecting sexual risk groups, highly connected nodes and bridge nodes between possible sub-clusters with high growth potential. CONCLUSIONS HIV transmission in Mexico City is strongly driven by young MSM with higher education level and recent infection. Nevertheless, leveraging network inference, we identified actively growing clusters that could be prioritized for focused intervention with demographic and risk characteristics that do not necessarily reflect the ones observed in the overall clustering population. Further studies evaluating different models to predict growing clusters are warranted. Focused interventions will have to consider structural and risk disparities between the MSM and the heterosexual populations.

Abstract
In the late 1990s antiretroviral pharmaceuticals began to be used in the United States and Western Europe to prevent HIV infection in contexts of occupational exposure. One decade later, the application of Post Exposure Prophylaxis (PEP) and Pre-Exposure Prophylaxis (PrEP) had been extended to include cases of exposure to sexual assault, injection-drug use, and consensual sexual intercourse deemed at high risk. This article explores the implementation of biomedicalized HIV prevention protocols at a public healthcare clinic in Mexico City, building on sociological-feminist approaches in Science and Technology Studies (STS) and drawing on interviews with key actors, as well as digital ethnography. We emphasise the stratified biomedicalization or, said otherwise, the differences in PEP and PrEP accessibility and consumption among different populations and groups. We also describe the fragile grip of institutionalised biomedical solutions when alternative 'moral economies' intersect with them, particularly in contexts like Mexico, where governmental funding for experimental research on biomedical innovations has been limited. This text reveals both the existence of contrasting technoscientific interventions along class and gender differences, and the multiple and vivid ways by which individuals appropriate and interpret global biomedical practices.

Abstract
Few studies have examined the relationship between inconsistent condom use and sexual partnership characteristics among people living with HIV (PLWH). The current study focused on such association and its gender differences. The study was conducted in a large hospital in South China in 2013. A total of 320 dyads (PLWH indexes and their sexual partners) were recruited from an outpatient clinic using convenience sampling. The proportion of inconsistent condom use in the last six months among female indexes was higher than that among male indexes (52.4% vs. 43.6%). Of sexual partnership characteristics, HIV seropositive status was a risk factor for inconsistent condom use for both male and female indexes (aOR = 2.32, 95%CI = 1.15∼4.66, aOR = 3.09, 95%CI = 1.10∼8.67, respectively). For male indexes, lower educational level was also a risk factor (aOR = 2.39, 95%CI = 1.23∼4.67); while having had emotionally intimate relationships was a protective factor (aOR = 0.40, 95%CI = 0.21∼0.77). For female indexes, receiving material support was a risk factor (aOR = 10.17, 95%CI = 2.13∼48.61) and receiving health-related advice was a protective factor (aOR = 0.11, 95%CI = 0.02∼0.55). Future HIV interventions for PLWH need to be gender-sensitive and include their sexual partners.

Abstract
BACKGROUND HIV pretreatment drug resistance (PDR) to NNRTIs in persons initiating ART is increasing in Mexico. OBJECTIVES To compare HIV PDR in eight sub-regions of Mexico. PATIENTS AND METHODS A large PDR survey was implemented in Mexico (September 2017-March 2018) across eight sub-regions. All larger clinics (which provide ART to 90% of all initiators) were included, allocating sample size using the probability-proportional-to-size method. Both antiretroviral-naive and prior antiretroviral-exposed persons were included. HIV PDR levels were estimated from pol Sanger sequences obtained at a WHO-designated laboratory. RESULTS A total of 2006 participants were enrolled from 74 clinics. PDR to NNRTIs was higher than to other drug classes (P < 0.0001), crossing the 10% threshold in the North-East, East, South-West and South-East. NNRTI PDR was higher in the South-West (P = 0.02), coinciding with the highest proportion of restarters in this sub-region (14%). We observed higher PDR prevalence to any drug in women compared with men (16.5% versus 12.2%, P = 0.04). After multivariable adjustment, higher NNRTI PDR remained significantly associated with previous antiretroviral exposure in the Centre-North, North-West, South-West and South-East [adjusted OR (aOR): 21, 5, 8 and 25, respectively; P < 0.05]. Genetic network analyses showed high assortativity by sub-region (P < 0.0001), with evidence of drug resistance mutation transmission within local clusters. CONCLUSIONS Diversification of the public health response to HIV drug resistance based on sub-regional characteristics could be considered in Mexico. Higher NNRTI PDR levels were associated with poorer regions, suggesting opportunities to strengthen local HIV programmes. Price and licensing negotiations of drug regimens containing integrase inhibitors are warranted.

Abstract
National HIV preventive programs in Mexico focus on high-risk groups that do not consider women, apart from prenatal screening. Nonetheless, the epidemic in women is growing, and there is a need to better understand sociodemographic factors in women living with HIV (WLH). We performed a case-control study in Mexico City, including HIV+ and HIV- women with a recent pregnancy to compare their sociodemographic characteristics and describe the circumstances of diagnosis in HIV+ women, as well as prenatal screening frequency in both groups. Fifty cases and 102 controls were interviewed. HIV+ women were more frequently the only economic support of the family (20% vs 0%, P < .0001). Thirty-eight percent of cases had their first pregnancy at ≤18 years, versus 16% of controls (odds ratio 2.47, 95% confidence interval 1.07-5.72, P = .03); 16% of cases had lived in the street; 6% reported transactional sex, versus none of the controls (P < .0001). In the multivariate analysis, there was strong evidence of an association between HIV infection and age at the time of the interview, history of sexually transmitted diseases, substance abuse, history of violence, and civil status. Only 6% of controls were tested for HIV during prenatal follow-up. WLH in this study faced important social vulnerability. Targeting women living in these social contexts might increase early diagnosis and could tailor HIV prevention strategies. Prenatal coverage needs to be improved and should represent a national priority.

CD4 Counts at Entry to HIV Care in Mexico for Patients under the "Universal Antiretroviral Treatment Program for the Uninsured Population," 2007-2014. PLoS One 2016; 11:e0152444. [PMID: 27027505 PMCID: PMC4814060 DOI: 10.1371/journal.pone.0152444] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2015] [Accepted: 03/14/2016] [Indexed: 01/24/2023] Open
Abstract
In Mexico, public health services have provided universal access to antiretroviral therapy (ART) since 2004. For individuals receiving HIV care in public healthcare facilities, the data are limited regarding CD4 T-lymphocyte counts (CD4e) at the time of entry into care. Relevant population-based estimates of CD4e are needed to inform strategies to maximize the impact of Mexico's national ART program, and may be applicable to other countries implementing universal HIV treatment programs. For this study, we retrospectively analyzed the CD4e of persons living with HIV and receiving care at state public health facilities from 2007 to 2014, comparing CD4e by demographic characteristics and the marginalization index of the state where treatment was provided, and assessing trends in CD4e over time. Our sample included 66,947 individuals who entered into HIV care between 2007 and 2014, of whom 79% were male. During the study period, the male-to-female ratio increased from 3.0 to 4.3, reflecting the country's HIV epidemic; the median age at entry decreased from 34 years to 32 years. Overall, 48.6% of individuals entered care with a CD4≤200 cells/μl, ranging from 42.2% in states with a very low marginalization index to 52.8% in states with a high marginalization index, and from 38.9% among individuals aged 18-29 to 56.5% among those older than 50. The adjusted geometric mean (95% confidence interval) CD4e increased among males from 135 (131,142) cells/μl in 2007 to 148 (143,155) cells/μl in 2014 (p-value<0.0001); no change was observed among women, with a geometric mean of 178 (171,186) and 171 (165,183) in 2007 and 2014, respectively. There have been important gains in access to HIV care and treatment; however, late entry into care remains an important barrier in achieving optimal outcomes of ART in Mexico. The geographic, socioeconomic, and demographic differences observed reflect important inequities in timely access to HIV prevention, care, and treatment services, and highlight the need to develop contextual and culturally appropriate prevention and HIV testing strategies and linkage programs.

Do not forget the boys - gender differences in children living in high HIV-affected communities in South Africa and Malawi in a longitudinal, community-based study. AIDS Care 2016; 28 Suppl 2:100-9. [PMID: 27392005 PMCID: PMC4991231 DOI: 10.1080/09540121.2016.1176680] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2016] [Accepted: 03/23/2016] [Indexed: 01/11/2023]
Abstract
Gender is an important factor in child development. Especially in sub-Saharan Africa, girls have often been shown to be less likely to access education compared to boys. The consequence of this has been that that programmes addressing child development are often aimed at girls in order to redress gender imbalances. This study examines the effect of gender on the development of children attending community-based organisations in high HIV-affected areas, and explores whether community-based organisation attendance was associated with any changes in gender differences over time. Baseline data from 989 children and 12-15 month follow from 854 (86% response rate) were used to examine gender differences in children from Malawi and South Africa. At baseline, where there were differences by gender, these tended to disadvantage boys. It was found that boys were significantly more often found to be subjected to violence. Boys showed worse performance at school and more behavioural problems than girls. These gender differences persisted from baseline to follow-up. At follow-up, boys self-reported significantly worse average quality of life than girls. Only harsh discipline differed by gender in progression over time: boys experienced a stronger reduction in harsh physical discipline than girls from baseline to follow-up. Since harsh discipline was associated with boys' worse educational outcomes and behavioural problems, our data cautiously suggests that gender differences could be reduced over time. In conclusion, our data suggests that, perhaps due to the narrow equity approach focusing on provision for girls, boys may be overlooked. As a result, there are some specific experiences where boys are generally worse off. These differences have distinct ramifications for the educational and emotional development of boys. A broader equity approach to child development might be warranted to ensure that the needs of both girls and boys are considered, and that boys are not overlooked.
