HIV treatment cascade and associated factors among men who have sex with men in Brazil: a cross-sectional study Ligia Kerr, Marto Leal, Ana Zaira da Silva, Ana Rita C. Motta-Castro, Regina Moreira, Luis Fernando de Macedo Brígido, Andréa F. Leal, Daniela Knauth, Maria Amélia Veras, Ana Maria de Brito, Edgar Merchán-Hermann, Ximena Pamela Díaz Bermudez, Alexandre Kerr Pontes, Raimunda Hermelinda M. Macena, Luana N. C. Lima, Mark Drew Crosland Guimarães, Inês Dourado, Lisângela Cristina Oliveira, Laio Magno, Igor Generoso, Claudia Renata dos Santos Barros, Carl Kendall Scientific Reports, 2026 Men who have sex with men (MSM) have been disproportionately affected by the human immunodeficiency virus (HIV) epidemic. The HIV treatment cascade is an important clinical monitoring strategy that involves the number of MSM living with HIV in health services. This study aimed to analyze the HIV treatment cascade in the MSM population in Brazil and to identify factors associated with different cascade stages. A cross-sectional study was conducted in 12 Brazilian capitals and included 4,176 MSM recruited through respondent-driven sampling in 2016. Factors associated with each stage of the HIV treatment cascade (outcomes), i.e., HIV diagnosis, use of antiretroviral therapy, and achievement of undetectable viral load, were identified via logistic regression. Approximately 18.3% (95% CI: 15.4–21.7) of the MSM were diagnosed with HIV at the time of the survey. Among those living with HIV, only 55.5% (95% CI: 46.2–64.4) had previous knowledge of their serologic status, and 98.4% (95% CI: 96.3–99.3) of those aware of their status used antiretroviral therapy. Among those reporting using antiretroviral therapy, 80.0% (95% CI: 64.8–89.7) had a suppressed viral load, whereas 79.4% (95% CI: 64.4–89.2) had an undetectable viral load. Age > 25 years, having completed high school or higher, having a previous diagnosis of another sexually transmitted infection, and not being identified as bisexual were positively associated with all outcomes. Once enrolled in HIV treatment programs, most MSM achieve viral suppression. The challenge for HIV control is that fully half of our sample or men who tested positive did not know their HIV status. Regardless of the reason for this lack of testing, Brazil faces a continuing HIV epidemic.

Amid Ecuador's rapid nutrition transition, we examined the prevalence of TBM and its components among preschool children and assessed inequalities by sociodemographic characteristics and poverty. Methods: We analysed nationally representative data from the 2022-23 National Survey on Child Undernutrition among children aged 0-59 months. Nutritional outcomes were defined using WHO standards. Weighted bi-probit, logistic and ordinal logistic regression models were used to examine associations between malnutrition and child, maternal, household characteristics and poverty indicators, adjusting for demographic factors. Findings: Stunting or wasting affected 17.1% (95% CI: 17.2-19.1) of children under 5 (n = 1,293,325), initially higher in boys, then shifting to girls by age three, with the highest prevalence among Indigenous children. Overweight prevalence was 4.9% (95% CI: 4.5-5.4), higher in boys, and highest among White children aged 18-53 months. Coexistence of undernutrition and overweight affected 0.6% (95% CI 0.5-0.7) or ∼7760 children, primarily boys under three. Among children aged 6-59 months (n = 1,172,450), severe anaemia affected 14.8% (95% CI 13.9-15.7) and 0.33% (95% CI 0.24-0.40; n = 3869) experienced TBM, disproportionately among socially disadvantaged Indigenous and Afro-Ecuadorian boys under three. Interpretation: Childhood malnutrition in Ecuador exhibits overlapping, socially patterned, and spatially clustered burdens, concentrated in early childhood. Addressing TBM requires integrated, early, equity-focused "triple-duty" targeted strategies that concurrently tackle undernutrition, overweight, and anaemia as interconnected manifestations of structural inequities. Funding: This research was funded by the NIHR (grant NIHR134801) using UK international development funding from the UK Government to support global health research.
Quality Assessment Indicators for Well-Child Care in Primary Health Care: A Scoping Review of Global Trends, Standardization, and Dimensions of Care Priscila Ribas de Farias Costa, Márcia Oliseski, Rita de Cássia Ribeiro-Silva, Ana Zaira da Silva, Rejane Queiroz, Carlos Lira, Izabele Lôbo, Elzo Pinto Júnior, Galba Freire Moita, Maria del Pilar Quispe, Maria Yury Ichihara, Rafael Barros, Carl Kendall, Ítalo Aguiar, Anya Vieira-Meyer, Rosa Livia Freitas de Almeida, Márcia Machado, Lígia Kerr Children, 2026 Background/Objectives: Well-child care plays a critical role in promoting child health and monitoring growth and development within Primary Health Care (PHC), in line with international frameworks such as the WHO Global Strategy and the UN Sustainable Development Goals (SDGs). However, the absence of standardized quality indicators limits comparability across studies and hinders continuous improvement worldwide. This study aimed to map and analyze the indicators used to assess the quality of well-child care in global PHC settings. Methods: A scoping review was conducted following PRISMA-ScR and Joanna Briggs Institute methodological guidance, with a pre-registered protocol. Comprehensive searches were performed in May 2025 across fourteen databases and two gray literature sources, without language or time restrictions. Eligible studies assessed quality indicators for well-child care among children up to 5 years, 11 months, and 29 days. Two independent reviewers performed study selection and data extraction. Results: From 6052 records, 62 studies met inclusion criteria. Out of them, most (68%) used composite indicators, primarily from pre-existing tools (67%). While structural and clinical indicators—such as immunization and service accessibility—were predominant, there was a critical absence of relational indicators focusing on patient–provider interaction. This lack of standardization and neglect of the relational dimension significantly hinders international comparability and the assessment of family-centered care quality. Conclusions: Developing and validating a core set of standardized, comprehensive, and context-sensitive indicators integrating structural, clinical, and relational dimensions is essential. These should be linked to information systems to enable robust national and international comparison, strengthen evidence-based management, and drive continuous quality improvement to achieve the 2030 Agenda goals. These findings provide a foundation for policymakers to develop standardized monitoring tools that prioritize neglected relational aspects of care.
Public-private mix in health systems and repercussions for health inequalities in Latin American countries: A scoping review protocol Eduarda Ferreira dos Anjos, Suelen Carlos de Oliveira, Adriana Mendoza-Ruiz, Maria del Pilar Flores-Quispe, Adelyne Maria Mendes Pereira, Carl Kendall, Ligia Regina Franco Sansigolo Kerr, Naiá Ortelan, Elzo Pereira Pinto Junior, Natalia Romero, Alastair Leyland, Mauricio Lima Barreto, Cristiani Vieira Machado, and Plos One, 2026 Introduction Health system models in Latin American countries express differences in the state’s role in regulating, financing and providing health services, as well as in the coexistence of different care arrangements involving public and private entities. This scoping review will seek to identify evidence on how the different public-private configurations of health systems influence health inequalities in Latin America. Methods and analysis This protocol will be guided by the scoping review methodology developed by the Joanna Briggs Institute. The results will be presented according to the PRISMA-ScR protocol. Searches will be carried out on the Scielo, Lilacs, Embase, Pubmed, Web of Science and Scopus databases. The inclusion criteria will be publications whose central theme is the public-private mix of health systems in Latin America between January 2000 and March 2024. Exclusion criteria will be clinical trials, incomplete studies or in the design phase, duplicate publications, pre-print studies and gray literature (interim reports, unpublished texts, dissertations, and theses. The steps for carrying out the scope review will: (1) identifying the research question; (2) identifying relevant studies; (3) study selection; (4) charting the data; and (5) collating, summarizing, and reporting the results. Two independent reviewers will select the articles. The results will be described, analyzed, and categorized through narrative synthesis, correlating with the research objectives and questions. Expected results It is hoped that this scoping protocol will provide a comprehensive framework for investigating the gaps in the current literature on the public-private mix in Latin America and the effects on health inequalities.

Adverse childhood experiences and use of corporal punishment among women in low-resource settings: a convergent mixed methods study with mothers of children under five in the Dominican Republic Adrianne Katrina Nelson, Melanie P. Frías, Martha Vibbert, Carl Kendall, Laura Sánchez-Vincitore, Heidi Luft, Michelle M. Susana, Katherine Theall, Arachu Castro BMC Women S Health, 2025 Background Evidence suggests that women who experience corporal punishment as a child are more likely to use it with their children, particularly in low-resource settings where higher exposure to additional adverse childhood experiences, such as food insecurity and a parent’s premature death or abandonment, compounds damage from early exposure to corporal punishment. However, mothers who experienced corporal punishment as a child and simultaneously kind, compassionate, secure caregiving from the same or another caregiver, are less likely to expose their children to corporal punishment. Not enough research investigates how early maternal experiences with corporal punishment impact everyday parenting behaviors in contexts of poverty outside high-income countries. This investigation seeks to provide actionable information for researchers and practitioners to support families to heal from intergenerational trauma in settings of poverty. Methods We used a convergent mixed methods design to understand how early experiences with corporal punishment shape parenting practices. We conducted a brief demographic and health questionnaire followed by in-depth semi-structured open-ended interviews with 25 mothers (19—42 years old) of low socioeconomic position in the Dominican Republic, who had children 3–5 years old at the time of the interview. Women offered reflections about how they believe their childhood experiences shaped their approach to parenting. We analyzed interview content using thematic analysis, comparing themes between women who use corporal punishment and those who do not. Results Fourteen women reported not using corporal punishment and 11 reported using it. A large majority of all participants described receiving corporal punishment as a child (79% of those who do not use corporal punishment and 82% of those who do). Participants often struggled to remember experiences from childhood and became emotionally disconnected or desensitized when discussing abusive events from their early life. Some participants expressed wanting to raise their children without corporal punishment, however they could not always control their impulses. A few mothers demonstrated resolution when discussing their early experiences with corporal punishment. Adolescent mothers reported using corporal punishment with their child much more frequently than older mothers, with only one mother over the age of 20 at the birth of her first child using corporal punishment. Those who used corporal punishment with their child also reported higher rates of characteristics suggesting lower socioeconomic position. We identified two main categories for participant explanations for the use of corporal punishment: (1) a disciplinary strategy used after escalated threats, or (2) a response to feeling overwhelmed. Whether mothers considered corporal punishment a violent parenting behavior depended on whether it led to injury, what part of the body was targeted, its regularity, and whether they perceived its use was warranted. Conclusions For early child interventions to be effective at preventing use of corporal punishment among women of low socioeconomic position in the Dominican Republic, practitioners should consider low-cost, scalable community-based therapeutic programs that address the impact of traumatic early childhood experiences.
Network Meta-Analytical Investigations of the Performance of HIV Combination Prevention Strategies for Indigenous Populations Marcos Jessé Abrahão Silva, Rebecca Lobato Marinho, Daniele Melo Sardinha, Diego Rafael Lima Batista, Luiza Raquel Tapajós Figueira, Tamires de Nazaré Soares, Keitty Anne Silva Neves, Aloma Mapinik Suruí, Manuella Nunes Colaço, Vinicius dos Santos Peniche, Ligia Regina Franco Sansigolo Kerr, Sebastião Kauã de Sousa Bispo, Ana Judith Pires Garcia, Carl Kendall, Luana Nepomuceno Gondim Costa Lima Viruses, 2025 Background: Indigenous populations worldwide face a disproportionate burden of HIV due to structural inequities, cultural marginalization, and limited access to health services. Despite growing recognition of the need for culturally adapted responses, the effectiveness of combination HIV prevention strategies in these communities remains underexplored. Objectives: This study aimed to evaluate and compare the effectiveness of multiple HIV prevention strategies among Indigenous populations using a systematic review and network meta-analysis (NMA), to inform equity-oriented public health interventions. Methods: Following PRISMA-NMA 2020 guidelines, a comprehensive literature search was conducted across four databases (PubMed, SciELO, LILACS, Science Direct) for quantitative studies published between January 2000 and June 2025. Eligible studies evaluated HIV prevention interventions among Indigenous populations and reported risk or odds ratios. A frequentist NMA model was used to calculate effect estimates (OR, 95% CI) and SUCRA rankings for seven types of interventions, combining biomedical, behavioral, and structural approaches. Results: Four high-to-moderate quality studies enclosing 4523 participants were included. The most effective intervention was home-based counseling and testing for HIV, followed by medical consultation combined with HIV testing. Standalone testing, while effective, was significantly less impactful than when combined with culturally sensitive educational strategies. Information-only strategies showed the least efficacy. The SUCRA analysis ranked home-based testing highest (45.17%), highlighting the importance of decentralization, community participation, and intercultural mediation. Conclusions: Culturally adapted combination prevention strategies—especially those integrating home-based testing and counseling—are more effective than isolated biomedical interventions in Indigenous populations. These findings reinforce the urgent need for participatory, context-driven public health responses that center Indigenous knowledge, reduce stigma, and expand equitable access to HIV care and prevention.
Syndemic Factors Associated with Zika Virus Infection Prevalence and Risk Factors in a Cohort of Women Living in Endemic Areas for Arboviruses in Northeast Brazil Ligia Kerr, Carlos Sanhueza-Sanzana, Marto Leal, Italo Aguiar, Kasim Allel, Moisés H. Sandoval, Cristiane Cunha Frota, Marco Túlio Aguiar, Adriano Ferreira Martins, Livia Dias, Rosa Livia Freitas de Almeida, Francisco Herlânio Costa Carvalho, Francisco Gustavo Silveira Correia, Roberto da Justa Pires Neto, Fernanda Montenegro Araújo, Shirlene Telmos Silva de Lima, Leda Maria Simões Mello, Lucas de Lima Nogueira, Terezinha do Menino Jesus Silva Leitão, Maria da Glória Teixeira, Jeni Stolow, Guilherme Loureiro Werneck, Ivo Castelo Branco Coelho, Ronald Blanton, Ana Zaira da Silva, George W. Rutherford, Carl Kendall Tropical Medicine and Infectious Disease, 2025 Background: We sought to explain the seroprevalence of Zika Virus (ZIKV) as a syndemic of socioeconomic, environmental, and health factors in a cohort of women living in Brazil. Methods: This is a cohort study comprising 1498 women between 15 and 39 years of age followed up in two waves between February 2018 and August 2019. Two questionnaires addressed the arbovirus’s socioeconomic, demographic, and behavioral aspects and participants’ arbovirus infection history. Blood samples were collected to detect IgM and IgG for ZIKV, chikungunya virus (CHIKV), and dengue virus (DENV), and RT-PCR for ZIKV. Results: The baseline prevalence for ZIKV was 43% (95%CI: 40.5, 45.6), increasing to 44.7% in the following period (95%CI: 42, 47.1). We found a prevalence of 44.1% among women having one syndemic factor, 49.9% for those having two, and 58% for women having three or more factors. Women reporting a single syndemic factor resulted in higher odds of acquiring ZIKV (OR = 1.6, 95%CI: 1.2–2.4). There were increased adjusted odds among women having two or three or more factors (OR = 2.1, 95%CI: 1.6–3.1; OR = 2.9, 95%CI: 2.0–4.3, respectively). Conclusions: Tailored interventions targeting syndemic conditions, such as the co-circulation of urban arboviruses and poor living conditions, are crucial to improving the burden produced by ZIKV.
Hepatitis C Care in the Greater New Orleans Area: Patient Perspectives on the Barriers and Facilitators to Care Brittany L. Lane, David W. Seal, Dielda J. Robertson, Carl Kendall, Casey D. Xavier Hall, Osaro Mgbere, Patricia J. Kissinger Journal of Health Care for the Poor and Underserved, 2025 Increasing engagement in hepatitis C virus (HCV) care and treatment will help mitigate HCV incidence, morbidity, and mortality in the United States. This study aimed to understand the multilevel factors affecting engagement in HCV care after implementation of a subscription-based payment model for HCV treatment. Semi-structured interviews were conducted with patients with chronic HCV from a federally qualified health center in New Orleans, Louisiana. We used a convenience sampling method to recruit patients for the study. The interviews conducted between May 2020 and February 2021 explored factors influencing linkage to and retention in HCV care, using the socio-ecological model as the guiding framework. An analysis of the interviews with 39 patients revealed multilevel barriers to care, including instability, provider attitudes, prior care experiences, and the corrections system. Facilitators identified included personal health journey, network HCV experiences, and HCV awareness. A multilevel approach to facilitate engagement in HCV care is imperative.
Home-based nurturing care practices for children under five with low socioeconomic position in Santo Domingo, Dominican Republic Adrianne Katrina Nelson, Laura Sánchez-Vincitore, Melanie Patricia Frias, Michelle Marie Susana, Carl Kendall, Katherine Theall, Martha Vibbert, Heidi Luft, Arachu Castro Plos One, 2025 Background In the Dominican Republic about 14.5% of children do not reach their full potential by age five, with children of low socioeconomic position most affected. The Nurturing Care Framework is an evidence-informed actionable framework to help children thrive, but we must first understand cultural contexts and childrearing practices that contribute to delay. This study applies the Nurturing Care Framework to explore the context of home-based care among young children in the Dominican Republic. Methods We conducted a sociodemographic survey and semi-structured qualitative interview with 25 mothers ages 19–42 (7 under the age of 18 at first birth) with low socioeconomic position and children under five that live in the capital city Santo Domingo. We asked in-depth questions about the Nurturing Care Framework’s domains of responsive caregiving and opportunities for early learning. We used consensual coding and deductive thematic analysis to analyze transcriptions, examined convergence and divergence in themes between adolescent and adult mothers, and organized themes using concept mapping. Results A few mothers provide responsive caregiving to their child, but they are unaware of its benefit to their child’s development. Adolescent mothers expressed lower confidence in their mothering skills. Across age groups, mothers did not see themselves as agents of change in their child’s early learning process and allow several hours of videos each day. Mothers provide children opportunities for learning through social interaction, a possible strength among this population. With regards to security and safety, about half of mothers use corporal punishment, all but one of these is an adolescent mother. Conclusion Findings highlight the need for parenting programs that build on strengths such as child-to-child social interaction and provide parents with opportunities to develop knowledge and skills to provide early learning opportunities. Interventions should target families with low socioeconomic position and adolescent mothers.
Prevalence and Characteristics of Children and Adolescents Engaged in Commercial Sex in the Recife Metropolitan Area, Pernambuco, Brazil Ana Maria de Brito, Marto Leal, Renata Barrett Fernandes de Almeida, Carolina Vasconcelos de Almeida Neves, Elizabeth J Anderson, Matilde Chora, Helen Shipman, Ligia Kerr, Carl Kendall Journal of Human Trafficking, 2025 This study estimates the population size of female minors (i.e. less than 18 years of age) involved in commercial sexual exploitation of children (CSEC) in the Recife Metropolitan Area (RMA), Pernambuco, Brazil. Secondarily, it explores sociodemographic and behavioral characteristics of CSEC. We used 1) the Successive Sampling Population Size Estimation (SS-PSE) method via Respondent-Driven Sampling among young women engaged in commercial sex, ages 18–21, who began exchanging sex for money, favors, or goods or were otherwise commercially sexually exploited at least once before their 18th birthday, and 2) the Network Scale-Up Method (NSUM) with a direct-dial random sample of RMA residents. Median population size estimates were 19,472 (NSUM) and 36,165 (SS-PSE) individuals. In addition to providing results for global trafficking indicators and documenting forms of violence perpetrated against CSEC survivors, this paper contributes to UN Sustainable Development Goal 5 by increasing knowledge about a form of gender-based violence that largely stems from poverty, and identifies possible CSEC prevention pathways. The large population size estimated and disparity between the two estimates contributes to the global debate – both methodological and practical – about the pursuit of exact population estimates and prevalence rates for human trafficking and the best methods to achieve them.
