Core data set para la generación de datos de la vida real en esclerosis múltiple: adaptación de una iniciativa global para América Latina / Core data set for real world data in multiple sclerosis: customization for latin america from a global task force recommendation

Introducción: Los objetivos primarios del core data set son reducir la heterogeneidad y promover la armonización entre las fuentes de datos en la esclerosis múltiple (EM), reduciendo así el tiempo necesario para ejecutar esfuerzos en la recolección de datos de vida real. Recientemente, un grupo liderado por la Multiple Sclerosis Data Alliance ha desarrollado un core data set para la recolección de datos del mundo real en EM a nivel global. Nuestro objetivo ha sido adaptar y consensuar este conjunto de datos globales a las necesidades de América Latina para que pueda ser implementado por los registros ya desarrollados y en proceso de desarrollo en la región. Material y métodos. Se conformó un grupo de trabajo regionalmente y se adaptó el core data set creado globalmente (proceso de traducción al español, incorporación de variables regionales y consenso sobre variables que se iban a utilizar). El consenso se obtuvo a través de la metodología Delphi remoto de ronda de cuestionarios y discusión a distancia de las variables del core data set. Resultados: Veinticinco profesionales de América Latina llevaron adelante el proceso de adaptación entre noviembre de 2022 y julio de 2023. Se estableció un acuerdo sobre un core data set de nueve categorías y 45 variables, versión 2023, con la sugerencia de implementarlo en registros desarrollados o en vías de desarrollo y cohortes de EM en la región. Conclusión: El core data set busca armonizar las variables recolectadas por los registros y las cohortes de EM en América Latina con el fin de facilitar dicha recolección y permitir una colaboración entre fuentes. Su implementación facilitará la recolección de datos de vida real y la colaboración en la región.(AU)

Introduction: The primary objective of the core data set is to reduce heterogeneity and promote harmonization among data sources in EM, thereby reducing the time needed to execute real life data collection efforts. Recently, a group led by the Multiple Sclerosis Data Alliance has developed a core data set for collecting real-world data on multiple sclerosis (MS) globally. Our objective was to adapt this global data set to the needs of Latin America, so that it can be implemented by the registries already developed and in the process of development in the region. Material and methods: A working group was formed regionally, the core data set created globally was adapted (translation process into Spanish, incorporation of regional variables and consensus on variables to be used). Consensus was obtained through the remote Delphi methodology of a round of questionnaires and remote discussion of the core data set variables. Results: A total of 25 professionals from Latin America carried out the adaptation process between November 2022 and July 2023. Agreement was established on a core data set of nine categories and 45 variables, version 2023 to suggest its implementation in developed or developing registries, and MS cohorts in the region. Conclusion: The core data set seeks to harmonize the variables collected by registries and cohorts in MS in Latin America in order to facilitate said collection and allow collaboration between sources. Its implementation will facilitate real life data collection and collaboration in the region.(AU)

Clinical trial capacity building in a pandemic-outcome of a rapid site readiness project in Latin America.

Background: Latin America (Latam) has a tradition of large-scale vaccine trials. Because of fluctuating demand, many sites have downsized their infrastructure. Therefore, BMGF launched a clinical trial site-readiness initiative early in the coronavirus-2019 (COVID-19) pandemic including Latam countries between August and September 2020. This survey evaluated clinical development performance measures pre/post initiative (September 2022). Results: 20/21 prequalified sites participated in COVID-19 vaccine/drug development trials. 156 clinical trials (140 COVID-19 vaccine/drug trials) were initiated in the 2 years since prequalification, compared to 176 in the 5 years before. 33,428/37,810 participants were included in COVID-19 programs. The number of enrolled subjects/day across sites quadrupled from 15 (1-35) to 63 (5-300). The dropout rate was 6.8%. Study approval timelines were reduced from 60 (12-120) to 35 (5-90) days. Mean qualified staff was increased from 24 (6-80) to 88 (22-180). Conclusion: Clinical trial sites across Latam were successfully prequalified to participate in COVID-19 developments. For the 100 days mission of vaccine availability in a new pandemic sufficient and well-trained clinical trial sites readily available are essential. This is only achievable if sites-especially in low/middle-income countries-are maintained active through a constant flow of vaccine studies.

Persistent inequities in maternal mortality in Latin America and the Caribbean, 1990-2019.

BACKGROUND: Despite the resources and personnel mobilized in Latin America and the Caribbean to reduce the maternal mortality ratio (MMR, maternal deaths per 100 000 live births) in women aged 10-54 years by 75% between 2000 and 2015, the region failed to meet the Millenium Development Goals (MDGs) due to persistent barriers to access quality reproductive, maternal, and neonatal health services. METHODS: Using 1990-2019 data from the Global Burden of Disease project, we carried out a two-stepwise analysis to (a) identify the differences in the MMR temporal patterns and (b) assess its relationship with selected indicators: government health expenditure (GHE), the GHE as percentage of gross domestic product (GDP), the availability of human resources for health (HRH), the coverage of effective interventions to reduce maternal mortality, and the level of economic development of each country. FINDINGS: In the descriptive analysis, we observed a heterogeneous overall reduction of MMR in the region between 1990 and 2019 and heterogeneous overall increases in the GHE, GHE/GDP, and HRH availability. The correlation analysis showed a close, negative, and dependent association of the economic development level between the MMR and GHE per capita, the percentage of GHE to GDP, the availability of HRH, and the coverage of SBA. We observed the lowest MMRs when GHE as a percentage of GDP was close to 3% or about US$400 GHE per capita, HRH availability of 6 doctors, nurses, and midwives per 1,000 inhabitants, and skilled birth attendance levels above 90%. CONCLUSIONS: Within the framework of the Sustainable Development Goals (SDGs) agenda, health policies aimed at the effective reduction of maternal mortality should consider allocating more resources as a necessary but not sufficient condition to achieve the goals and should prioritize the implementation of new forms of care with a gender and rights approach, as well as strengthening actions focused on vulnerable groups.

Sporadic clone Escherichia coli ST615 as a vector and reservoir for dissemination of crucial antimicrobial resistance genes.

There is scarce information concerning the role of sporadic clones in the dissemination of antimicrobial resistance genes (ARGs) within the nosocomial niche. We confirmed that the clinical Escherichia coli M19736 ST615 strain, one of the first isolates of Latin America that harbors a plasmid with an mcr-1 gene, could receive crucial ARG by transformation and conjugation using as donors critical plasmids that harbor bla CTX-M-15, bla KPC-2, bla NDM-5, bla NDM-1, or aadB genes. Escherichia coli M19736 acquired bla CTX-M-15, bla KPC-2, bla NDM-5, bla NDM-1, and aadB genes, being only blaNDM-1 maintained at 100% on the 10th day of subculture. In addition, when the evolved MDR-E. coli M19736 acquired sequentially bla CTX-M-15 and bla NDM-1 genes, the maintenance pattern of the plasmids changed. In addition, when the evolved XDR-E. coli M19736 acquired in an ulterior step the paadB plasmid, a different pattern of the plasmid's maintenance was found. Interestingly, the evolved E. coli M19736 strains disseminated simultaneously the acquired conjugative plasmids in different combinations though selection was ceftazidime in all cases. Finally, we isolated and characterized the extracellular vesicles (EVs) from the native and evolved XDR-E. coli M19736 strains. Interestingly, EVs from the evolved XDR-E. coli M19736 harbored bla CTX-M-15 though the pDCAG1-CTX-M-15 was previously lost as shown by WGS and experiments, suggesting that EV could be a relevant reservoir of ARG for susceptible bacteria. These results evidenced the genetic plasticity of a sporadic clone of E. coli such as ST615 that could play a relevant transitional link in the clinical dynamics and evolution to multidrug/extensively/pandrug-resistant phenotypes of superbugs within the nosocomial niche by acting simultaneously as a vector and reservoir of multiple ARGs which later could be disseminated.

Pesticide contamination of lactating mothers' milk in Latin America: a systematic review.

OBJECTIVE: To identify the prevalence of contamination by pesticides and their metabolites in the milk of lactating mothers in Latin America. METHODS: In this systematic review, the PubMed, LILACS, Embase, and Scopus databases were searched up to January 2022 to identify observational studies. The Mendeley software was used to manage these references. The risk of bias assessment was evaluated according to the checklist for prevalence studies and writing design, by the Prisma guidelines. RESULTS: This study retrieved 1835 references and analyzed 49 studies. 69.38% of the analyzed studies found a 100% prevalence of breast milk contamination by pesticides among their sample. Main pesticides include dichlorodiphenyltrichloroethane (DDT) and its isomers (75.51%), followed by the metabolite dichlorodiphenyldichloroethylene (DDE) (69.38%) and hexachlorocyclohexane (HCH) (46.93%). This study categorized most (65.30%) studies as having a low risk of bias. CONCLUSIONS: This review shows a high prevalence of pesticide contamination in the breast milk of Latin American women. Further investigations should be carried out to assess contamination levels in breast milk and the possible effects of these substances on maternal and child health.

Reducing delivery insurance costs through risk score model for food delivery company.

In this paper, we propose a novel pricing model for delivery insurance in a food delivery company in Latin America, with the aim of reducing the high costs associated with the premium paid to the insurer. To achieve this goal, a thorough analysis was conducted to estimate the probability of losses based on delivery routes, transportation modes, and delivery drivers' profiles. A large amount of data was collected and used as a database, and various statistical models and machine learning techniques were employed to construct a comprehensive risk profile and perform risk classification. Based on the risk classification and the estimated probability associated with it, a new pricing model for delivery insurance was developed using advanced mathematical algorithms and machine learning techniques. This new pricing model took into account the pattern of loss occurrence and high and low-risk behaviors, resulting in a significant reduction of insurance costs for both the contracting company and the insurer. The proposed pricing model also allowed for greater flexibility in insurance contracting, making it more accessible and appealing to delivery drivers. The use of estimated loss probabilities and a risk score for the pricing of delivery insurance proved to be a highly effective and efficient alternative for reducing the high costs associated with insurance, while also improving the profitability and competitiveness of the food delivery company in Latin America.

Primary health care as a tool to promote equity and sustainability; a review of Latin American and Caribbean literature.

Primary health care (PHC) has increased in global relevance as it has been demonstrated to be a useful strategy to promote community access to health services. Multilateral organizations and national governments have reached a consensus regarding the basic principles of PHC, but the application of these varies from country to country due to the particularities of local health systems.This article aims to review and summarize PHC strategies and the configuration of health networks in Latin American and Caribbean countries.The review was carried out using keywords in at least 9 databases. Papers in languages other than English, Portuguese, and Spanish were excluded, while non-refereed articles and regional gray literature were incorporated. As a result, 1,146 papers were identified. After three instances of analysis, 142 articles were selected for this investigation. Data were analyzed according to an analysis by theme.The evidence collected on health reforms in the region reflects the need to intensify care strategies supported by PHC and care networks. These must be resilient to changes in the population's needs and must be able to adapt to contexts of epidemiological accumulation.

Implementing Standard Diagnosis and Treatment for Locally Advanced Breast Cancer Through Global Research in Latin America: Results From a Multicountry Pragmatic Trial.

PURPOSE: Breast cancer mortality rates in Latin America (LA) are higher than those in the United States, possibly because of advanced disease presentation, health care disparities, or unfavorable molecular subtypes. The Latin American Cancer Research Network was established to address these challenges and to promote collaborative clinical research. The Molecular Profiling of Breast Cancer Study (MPBCS) aimed to evaluate the clinical characteristics and treatment outcomes of LA participants with locally advanced breast cancer (LABC). PATIENTS AND METHODS: The MPBCS enrolled 1,449 participants from Argentina, Brazil, Chile, Mexico, and Uruguay. Through harmonized procedures and quality assurance measures, this study evaluated clinicopathologic characteristics, neoadjuvant chemotherapy response, and survival outcomes according to residual cancer burden (RCB) and the type of surgery. RESULTS: Overall, 711 and 480 participants in the primary surgery and neoadjuvant arms, respectively, completed the 5-year follow-up period. Overall survival was independently associated with RCB (worse survival for RCBIII-adjusted hazard ratio, 8.19, P < .001, and RCBII [adjusted hazard ratio, 3.69, P < .008] compared with RCB0 [pathologic complete response or pCR]) and type of surgery (worse survival in mastectomy than in breast-conserving surgery [BCS], adjusted hazard ratio, 2.97, P = .001). The hormone receptor-negative-human epidermal growth factor receptor 2-positive group had the highest proportion of pCR (48.9%). The analysis of the ASCO Quality Oncology Practice Initiative breast module revealed high compliance with pathologic standards but lower adherence to treatment administration standards. Notably, compliance with trastuzumab administration varied widely among countries (33.3%-88.7%). CONCLUSION: In LABC, we demonstrated the survival benefit of BCS and the prognostic effect of the response to available neoadjuvant treatments despite an important variability in access to key treatments. The MPBCS represents a significant step forward in understanding the real-world implementation of oncologic procedures in LA.

First large-scale study reveals important losses of managed honey bee and stingless bee colonies in Latin America.

Over the last quarter century, increasing honey bee colony losses motivated standardized large-scale surveys of managed honey bees (Apis mellifera), particularly in Europe and the United States. Here we present the first large-scale standardized survey of colony losses of managed honey bees and stingless bees across Latin America. Overall, 1736 beekeepers and 165 meliponiculturists participated in the 2-year survey (2016-2017 and 2017-2018). On average, 30.4% of honey bee colonies and 39.6% of stingless bee colonies were lost per year across the region. Summer losses were higher than winter losses in stingless bees (30.9% and 22.2%, respectively) but not in honey bees (18.8% and 20.6%, respectively). Colony loss increased with operation size during the summer in both honey bees and stingless bees and decreased with operation size during the winter in stingless bees. Furthermore, losses differed significantly between countries and across years for both beekeepers and meliponiculturists. Overall, winter losses of honey bee colonies in Latin America (20.6%) position this region between Europe (12.5%) and the United States (40.4%). These results highlight the magnitude of bee colony losses occurring in the region and suggest difficulties in maintaining overall colony health and economic survival for beekeepers and meliponiculturists.

Urban air pollution evaluation in downtown streets of a medium-sized Latin American city using AERMOD dispersion model.

The transport sector is considered the largest contributor of air pollutants in urban areas, mainly on-road vehicles, affecting the environment and human health. Bahía Blanca is a medium-sized Latin American city, with high levels of traffic in the downtown area during peak hours. In this regard, it is necessary to analyze air pollution using an air quality model considering that there are no air pollutant measurements in the central area. Furthermore, this type of study has not been carried out in the region and since the city is expected to grow, it is necessary to evaluate the current situation in order to make effective future decisions. In this sense, the AERMOD model (US-EPA version) and the RLINE source type were used in this work. This study analyzes the variations of pollutant concentrations coming from mobile sources in Bahía Blanca's downtown area, particularly carbon monoxide (CO) and nitrogen oxides (NOx) during the period Jul-2020 to Jun-2022. It is interesting to note the results show the maximum concentration values detected are not directly associated with maximum levels of vehicle flow or emission rates, which highlights the importance of meteorological parameters in the modeling. In addition, alternative scenarios are proposed and analyzed from a sustainable approach. Regarding the scenario analysis, it can be concluded that diesel vehicles have a large influence on NOx emissions. Moreover, restrictions as strict as those proposed for a Low Emission Zone would be less applicable in the city than alternative temporary measures that modify traffic at peak hours.

Ambientes amigos das pessoas idosas: avaliação de linha de base na América Latina com referência à Costa Rica

A consolidação de ambientes amigos das pessoas idosas é um dos objetivos da Década do Envelhecimento Saudável 2021–2030. O Programa de Cidades e Comunidades Amigas das Pessoas Idosas da Organização Mundial da Saúde (OMS) afirma que, para conseguir avançar nesse objetivo, é preciso primeiro fazer uma avaliação de linha de base, com a participação ativa das pessoas idosas, para determinar as áreas em que as cidades e comunidades devem trabalhar para remover as barreiras enfrentadas por esse grupo populacional e criar ambientes cada vez mais amigos das pessoas idosas e adaptados às suas necessidades. O programa da OMS recomenda o uso do Protocolo de Vancouver para essa avaliação. Devido às particularidades de sua implementação, muitos países latino-americanos fizeram adaptações a fim de promover a implementação local e superar as dificuldades encontradas. Com o objetivo de caracterizar o conhecimento atual disponível na América Latina e levar em consideração as experiências das cidades e comunidades da sub-região, este documento compila alguns exemplos e casos dessas adaptações, como o programa implementado na Costa Rica, que servirão para orientar ações de políticas visando ao desenvolvimento pleno das pessoas ao longo de todo o curso de vida. Para responder aos desafios impostos pela transição demográfica, é essencial criar ferramentas que permitam adaptar os ambientes de modo a favorecer o envelhecimento saudável, o que exige informações precisas, atualizadas e eficazes. A Década do Envelhecimento Saudável estabelece um período para orientar as ações de geração e monitoramento das informações. Este relatório faz parte dessa estratégia.

Age-friendly Environments: Baseline Assessment in Latin America with reference to Costa Rica

Consolidating age-friendly environments is a goal of the Decade of Healthy Ageing (2021–2030). Under the World Health Organization (WHO) Age-Friendly Cities and Communities Framework the first step is to carry out a baseline assessment, with the active participation of older people, in order to determine the areas in which cities and communities must work to remove the barriers experienced by older people and create increasingly friendly environments adapted to their requirements. The WHO program recommends using the Vancouver Protocol to conduct this assessment. Due to particular complications, many Latin American countries have adapted it for local implementation in order to overcome difficulties that arose. Outlining the current knowledge available in Latin America and noting the experiences of cities and communities in the subregion, this document compiles examples and case studies of these adaptations, such as the program implemented in Costa Rica, which will guide policy actions that foster people's full development throughout the life course. In order to respond to the challenges posed by demographic transitions, it is essential to create tools that allow environments to be adapted in ways that promote healthy ageing. This requires accurate, up-to-date, and effective information. The Decade of Healthy Ageing establishes a period of focused action aimed at producing and monitoring information. This is the strategy that serves as the framework for this report.

Cuantificación de la carga de la enfermedad renal crónica en América Latina: una epidemia invisibilizada / Quantification of the burden of chronic kidney disease in Latin America: an invisible epidemic / Quantificação da carga da doença renal crônica na América Latina: uma epidemia invisível

[RESUMEN]. Objetivo. 1) Describir la carga de la enfermedad renal crónica en países de América Latina entre 1990 y 2019 y, 2) Estimar la correlación entre los años de vida saludables perdidos (AVISA) con el índice sociodemográfico y el índice de acceso y calidad de salud. Métodos. Análisis secundario y ecológico, basado en el Estudio de la Carga Global de Enfermedades, Lesiones y Factores de Riesgo 2019. Se reportaron las tasas estandarizadas de mortalidad, años perdidos por muertes prematuras (APMP), años de vida ajustados por discapacidad (AVAD) y AVISA por enfermedad renal crónica para 1990, 2005 y 2019. La información se desagregó por países, sexo, grupos etarios y subcausas. Resultados. Entre 1990 y 2019, la carga de la enfermedad renal crónica aumentó considerablemente en los países de América Latina, convirtiéndose en una de las principales causas de mortalidad y de AVISA. La tasa estandarizada de AVISA por enfermedad renal crónica se debió, en gran medida, al peso de las muertes prematuras más que a la discapacidad. En 2019, Nicaragua, El Salvador, México y Guatemala se destacaron por tener las tasas estandarizadas de mortalidad por enfermedad renal crónica y de AVISA más elevadas, mientras que Uruguay presentó las más bajas. Conclusiones. La enfermedad renal crónica es una epidemia invisibilizada que representa una carga excesiva, en mortalidad y AVISA, para los países de América Latina. Es indispensable aunar esfuerzos regionales para enfrentar la enfermedad, además de impulsar acciones locales que atiendan las particularidades de cada país.

[ABSTRACT]. Objective. 1) Describe the burden of chronic kidney disease in Latin American countries between 1990 and 2019; and 2) Estimate the correlation between disability-adjusted life years (DALYs) and the Sociodemogra- phic Index and the Healthcare Access and Quality Index. Methods. Secondary and ecological analysis, based on the 2019 Global Burden of Diseases, Injuries and Risk Factors Study. Standardized mortality rates, years of life lost to due to premature death (YLLs),years of healthy life lost due to disability (YLDs) and DALYs due to chronic kidney disease were reported for 1990, 2005, and 2019. Information was disaggregated by country, sex, age group, and sub-cause. Results. Between 1990 and 2019, the burden of chronic kidney disease increased considerably in Latin Ame- rican countries, becoming one of the main causes of mortality and DALYs. The standardized rate of DALYs for chronic kidney disease was largely due to the weight of premature deaths rather than disability. In 2019, Nica- ragua, El Salvador, Mexico, and Guatemala had the highest standardized mortality rates for chronic kidney disease and DALYs, while Uruguay had the lowest. Conclusions. Chronic kidney disease is an invisible epidemic that places an excessive burden in terms of mortality and DALYs on Latin American countries. It is essential to join forces to tackle the disease in the region, and promote local actions that address the particularities of each country.

[RESUMO]. Objetivo. 1) Descrever a carga da doença renal crônica nos países da América Latina entre 1990 e 2019 e 2) estimar a correlação entre os anos de vida saudável perdidos (AVISA), o índice sociodemográfico e o índice de acesso e qualidade da saúde. Métodos. Análise secundária e ecológica, baseada no estudo Carga Global de Doenças, Lesões e Fatores de Risco 2019 (GBD). Foram informadas taxas de mortalidade padronizadas, anos de vida perdidos por morte prematura (AVP) por morte prematura, anos de vida ajustados por incapacidade (AVAI) e AVISA devido a doença renal crônica de 1990, 2005 e 2019. Os dados foram desagregados por país, sexo, faixas etárias e causas subjacentes. Resultados. Entre 1990 e 2019, a carga de doença renal crônica aumentou consideravelmente nos países da América Latina, tornando-se uma das principais causas de mortalidade e de AVISA. A taxa padronizada de AVISA devido à doença renal crônica foi influenciada em grande parte pelo peso das mortes prematuras, e não da incapacidade. Em 2019, Nicarágua, El Salvador, México e Guatemala se destacaram por terem as maiores taxas padronizadas de mortalidade por doença renal crônica e AVISA, ao passo que Uruguai teve as menores taxas. Conclusões. A doença renal crônica é uma epidemia invisível, que representa uma carga excessiva em ter- mos de mortalidade e de AVISA para os países da América Latina. É essencial unir esforços na região para combater a doença, além de promover ações locais que atendam às particularidades de cada país.

Food insecurity and sociodemographic factors in Latin America during the COVID-19 pandemic / Inseguridad alimentaria y factores sociodemográficos en América Latina durante la pandemia de COVID-19 / Insegurança alimentar e fatores sociodemográficos na América Latina durante a pandemia de COVID-19

[ABSTRACT]. Objective. To understand the association of food insecurity with sociodemographic factors in a sample popu- lation in Latin America during the COVID-19 pandemic. Methods. This was a multicenter cross-sectional study conducted in 10 countries in Latin America using an online survey through various digital platforms from October 14, 2020 to February 15, 2021. Statistical analysis of data was performed by applying descriptive statistics, chi-square test, and logistic regression analysis. Results. Of a total of 6 357 surveys, 58.2% of respondents experienced food security, 29.3% were slightly food insecure, 9.2% were moderately food insecure, and 3.3% were severely food insecure. Concerning the association food insecurity and sociodemographic variables, there is a significant association in the variables studied, including area of residence, education level, occupation, number of persons in the household, house- hold with children younger than 10 years of age, and socioeconomic level. Conclusions. These findings indicate that sociodemographic factors associated with food insecurity during the COVID-19 pandemic in Latin America were rural residence; complete and incomplete basic and secondary schooling; occupation (homemaker, unemployed, and self-employed); low, medium-low, and medium socioeco- nomic level; household with more than four persons; and household with children younger than 10 years of age.

Experiences of Providers and Immigrants/Refugees with Health Care: A Meta-Synthesis of the Latin American Context.

INTRODUCTION: The experiences of providers and immigrants/refugees related to healthcare in the Latin American context have not yet been aggregated. This study aimed to synthesize the qualitative evidence on this theme. METHOD: A systematic review of qualitative evidence with meta-synthesis. After identification, eligible studies were evaluated for methodological quality, and information was systematically analyzed. RESULTS: The sample comprised 26 articles. The meta-theme shows that the experiences of providers and immigrants/refugees are determined by multilevel factors. In a macro-context, these factors involve the vulnerabilities of immigrants/refugees and the healthcare system/model, and in a closer context, they involve the lack of professional training in cultural skills and communication; language barriers; and prejudice/xenophobia. Within healthcare, the relationship is mostly conflictual, asymmetric, and unable to solve problems, leading to negative repercussions for both. CONCLUSIONS: Managers involved in developing public policies and providers must consider improving the interrelationship between healthcare services and the migrant population.

A comprehensive analysis of children's blood lead levels in Latin America and the Caribbean over the last eight years: Progress and recommendations.

In 2017 we published a review on blood lead levels (BLL) in children from Latin America and the Caribbean (LAC) for data available up to 14th of March 2014 and recommended the identification and control of "lead hot spots". In the present study, an evaluation of progress toward reducing BLL in the region was carried out. A systematic review of the latest literature on lead exposure in the LAC region held on the PubMed, Web of Science and LILACS databases (January 2014 to March 2022) was conducted using the PRISMA methodology. Only original papers published in peer-reviewed English, Spanish, or Portuguese journals were eligible. A total of 558 papers were retrieved, 77 of which met the selection criteria and 31 (40.25 %) were carried out in Mexico. The prevalence of children with BLL above 10 µg. dL-1 was 22.08 % in the previous review versus 6.78 % in the current study. In the present review, the prevalence of children with BLL above 5 µg. dL-1 was 29.62 %, and only one study reported a BLL prevalence rate between 3.3 and 5 µg. dL-1. The highest BLLs were associated with well-known sources or occupational exposures. The number of countries (n = 13) that published data on BLL in children was lower compared to the previous review (n = 16). Most studies were conducted in areas with known lead exposure sources, similar to the earlier review. The percentage of children at risk of lead poisoning in the region remains unknown because few studies have published data on environmental exposure levels and most samples were relatively small. The recommendation to identify and control sources of lead exposure was maintained, while further suggestions for establishing a systematic public health surveillance system for lead were proposed to help reduce the knowledge gap and inform public health policy-making in LAC.

Suicide attempts in the absence of depression: Differences between broad cultural groups.

Suicide is one of the leading causes of death worldwide (WHO, 2021). Depression is a common precursor to suicide and suicidality; however, individuals' experience of depression and the meaning of suicide differs depending on one's cultural background (Colucci, 2013; Goodmann et al., 2021; Kleinman, 2004). The current study explores the relationship between suicide and depression among six broad cultural groups in a large sample (N = 17,015) of adults representing six broad cultural groups (Latin America, South Asia, former Soviet Bloc, Western English-speakers, Chinese, and Arab World). Participants were recruited to a multilingual depression and suicide screening study via Google Ads (Leykin et al., 2012; Gross et al., 2014). As expected, the presence of depression was associated with suicide attempts. However, cultural group moderated this association, with Chinese participants being most likely to report suicide attempts while screening negative for depression. Although depression remains an important predictor of suicidality, it appears that certain cultural groups may be at higher risk even when depression is not present. Clinicians should consider using culturally adapted assessments for depression and suicidality.

A systematic review of biobanks in Latin America: Strengths and limitations for biomedical research.

Biobanks are valuable tools for developing and applying scientific research and international cooperation through the collection of biological materials and their associated data. Systematic research following the Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines was conducted in late 2022 in PubMed and Scopus, and generated 17 articles to be reviewed in depth and critically assessed using the Critical Appraisal Skills Programme Checklist due to the limited available data; 12 relevant health organizations and government websites outside of peer-reviewed journals were also included. Our research identified 44 biobanks in Latin America. In general, there is a lack of regulation and legislation guaranteeing the stored materials' quality and institutional collaboration. We believe a consensus needs to be reached regarding the terminology and definitions used for biobanks. The design for informed consent should also be agreed upon to ensure the privacy of the data shared among institutions. In conclusion, in Latin America, there is a clear need for government support in creating specific procedures for biobanks and providing further support for existing biobanks.
