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
Tijuana, Mexico, has a concentrated HIV epidemic among overlapping key populations (KPs) including people who inject drugs (PWID), female sex workers (FSW), their male clients, and men who have sex with men (MSM). We developed a dynamic HIV transmission model among these KPs to determine the extent to which their unmet prevention and treatment needs is driving HIV transmission. Over 2020-2029 we estimated the proportion of new infections acquired in each KP, and the proportion due to their unprotected risk behaviours. We estimate that 43.7% and 55.3% of new infections are among MSM and PWID, respectively, with FSW and their clients making-up < 10% of new infections. Projections suggest 93.8% of new infections over 2020-2029 will be due to unprotected sex between MSM or unsafe injecting drug use. Prioritizing interventions addressing sexual and injecting risks among MSM and PWID are critical to controlling HIV in Tijuana.

Marks C, Zúñiga ML. CAM Practices and Treatment Adherence Among Key Subpopulations of HIV+ Latinos Receiving Care in the San Diego-Tijuana Border Region: A Latent Class Analysis. Front Public Health 2019; 7:179.

Abstract
Latinos living in the United States-Mexico border region bear a disproportionate HIV/AIDS burden compared to individuals living in the interior of both nations and face a constellation of barriers that determine their ability to access and adhere to HIV care. Use of complementary and alternative medicine (CAM) may be associated with suboptimal treatment adherence. Sociodemographic factors, health practices, and social determinants of health unique to the border region may further contribute to health disparities that undermine care engagement and continuity. Improved understanding of HIV-positive Latino subgroups and their risk profiles can lead to more effective, targeted clinical and public health interventions. We undertook this study to identify and characterize distinct classes of HIV-positive Latinos in the San Diego-Tijuana border region, differentiated by HIV and border-related factors, utilizing latent class analysis. We investigated relationships between class membership and CAM utilization and self-reported antiretroviral therapy (ART) adherence. Five distinct classes were identified with unique demographic, HIV risk, and border mobility profiles. CAM was recently used by nearly half of each class, though there were significant differences in the proportion of CAM use by class ranging from 44.4 to 90.9%. As well, all classes were currently receiving ART at similarly high rates and ART adherence outcomes were not significantly different based on class. Findings highlight the significant use of CAM by all HIV-positive Latinos in the border region and imply the need for a research framework which appropriately acknowledges the heterogeneous nature of this population, such as intersectionality. Further research is recommended into understanding how patients integrate CAM into HIV treatment and the risks and benefits of incorporating CAM into HIV treatment.

Abstract
Health and social care providers' perceptions of Black-Canadian parent-youth sexual health communication has important implications for addressing knowledge gaps in the provision of services to young people and their parents. Providers' perceptions are crucial as they often act as advisers in tailoring programmes or services to the perceived needs of parents and youth. To understand these perceptions, 17 semi-structured in-depth interviews were conducted with providers who worked with African, Caribbean or Black (ACB) parents and youth in Toronto, Ontario, Canada. Critical Race Theory was used to help guide the interpretation of findings. The findings revealed providers believed that many parents were unlikely to explicitly discuss sexual health or HIV prevention with young people. Additionally, providers perceived that the content of and approach to parent-youth sexual health communication differed between African and Caribbean clients. Moreover, providers believed that both parents' and young people's sex and gender impacted the quality, content and style of sexual health communication and had important implications for programme development. Overall, findings suggest a need for understanding the development of providers' perceptions of this communication, ways to address these perceptions and further parent-provider collaboration to promote Black youths' sexual health.

Abstract
Antiretroviral therapy for treatment of HIV infection has become increasingly effective. Persistent poor HIV outcomes in racial and ethnic minority populations in the US call for a closer examination into why Latinos are at significant risk for acquiring and dying from HIV. To improve clinical outcomes and achieve an AIDS-free generation, HIV research must address disparities in HIV outcomes in Latinos, the largest ethnic/racial minority population in the US. Immigrant status as well as cultural factors influence HIV care utilization and are essential to highlight for effective intervention development in Latinos. A better understanding of these individual and contextual factors is critical to developing tailored approaches to engaging Latinos in HIV care. Based on a comprehensive literature review, we offer a framework for understanding what is needed from clinical practice and research to improve engagement in HIV care for US-based Latinos. These findings may have implications for other minority populations.

Abstract
This report shares the challenges and opportunities encountered by a binational project that examined the availability of environmental and public health information for the United States-Mexico border area. The researchers interviewed numerous national and binational agencies on both sides of the border, endeavoring to develop a framework to advance the knowledge of academic and public health professionals in the area of environmental border health. However, the lack of standardized indicators and metrics in both countries validates the emergent need to establish a viable framework for the collection, analysis, and dissemination of environmental information. Recommendations for next steps are included.

Abstract
Border areas are particular "hot spots" generating high levels of HIV vulnerability and facing great challenges to control epidemics. The objective of this study is to describe the sociodemographic, clinical and biological profiles of newly HIV diagnosed people at the French Guiana - Suriname border, to construct an HIV care cascade and compare it with the Surinamese one. HIV-patients aged over 15 years newly diagnosed in western French Guiana in 2011 and 2012 were included in a retrospective cohort study. Patients were identified using different sources (n = 121). The male-to-female ratio was 0.8, 85% of the patients were of foreign origin, 72% were undocumented migrants, 21% were living in Suriname and 48% had baseline CD4 cell counts <200 cells/mm3. After one year, 34% were lost to follow-up, 54% received treatment, 34% had controlled viremia and 6% died. We observed a disappointing HIV cascade, like that of Suriname, requiring to develop a coordinated healthcare offer on both sides of the border. Targeted efforts through a bi-national collaboration are needed to address the specific issues of cross-border patients to reach the 90*3 UNAIDS's diagnosis, link to care and treatment targets and better control the local epidemic.
