The case for investment in tobacco control: lessons from four countries in the Americas.

Objective: To synthesize learnings from four national tobacco control investment cases conducted in the Americas (Colombia, Costa Rica, El Salvador, Suriname) under the World Health Organization Framework Convention on Tobacco Control (WHO FCTC) 2030 project, to describe results and how national health authorities have used the cases, and to discuss implications for the role of investment cases in advancing tobacco control.

Methods: We draw on findings from four national investment cases that included 1) a cost-of-illness analysis calculating the health and economic burden of tobacco use, 2) a return-on-investment analysis of implementing key tobacco control demand reduction measures, and 3) a subsidiary analysis of one tobacco control topic of national interest (e.g.

The health impacts of violence perpetrated by police, military and other public security forces on gay, bisexual and other men who have sex with men in El Salvador.

Gay, bisexual and other men who have sex with men face both high levels of violence and a disproportionate burden of poor health outcomes. We explored violence perpetrated against Salvadoran gay, bisexual and other men who have sex with men by public security forces; perceived motivations of violence; and impacts on health. We conducted structured qualitative interviews with 20 participants and used systematic coding and narrative analysis to identify emergent themes.

"We're Going to Leave You for Last, Because of How You Are": Transgender Women's Experiences of Gender-Based Violence in Healthcare, Education, and Police Encounters in Latin America and the Caribbean.

Transgender (trans) women experience gender-based violence (GBV) throughout their lives, which impedes their access to services and contributes to poor health outcomes and quality of life. To inform policies and health programs, trans women worked with the United States Agency for International Development (USAID)- and President's Emergency Plan for AIDS Relief (PEPFAR)-supported LINKAGES project, the United Nations Development Programme, The University of the West Indies, and local organizations to document experiences of GBV and transphobia in healthcare, education, and police encounters. Trans women conducted 74 structured interviews with other trans women in El Salvador, Trinidad and Tobago, Barbados, and Haiti in 2016.

Experiences of gender-based violence among female sex workers, men who have sex with men, and transgender women in Latin America and the Caribbean: a qualitative study to inform HIV programming.

Background: Female sex workers, MSM, and transgender women-collectively referred to as key populations (KPs)-are disproportionately affected by gender-based violence (GBV) and HIV, yet little is known about the violence they face, its gender-based origins, and responses to GBV. The purpose of this study was to understand the nature and consequences of GBV experienced, to inform HIV policies and programming and to help protect KPs' human rights.

Methods: Using a participatory approach, FSWs, MSM, and transgender women in Barbados, El Salvador, Trinidad and Tobago, and Haiti conducted 278 structured interviews with peers to understand their experiences of and responses to GBV.
