| Idioma(s): Inglés
This research aims at contributing to the use of Polymesoda arctata, Anadara tuberculosa, and Larkinia grandis as prospective biomonitors and sentinels, surrogate of Crassostrea rhizophorae for pollution biomonitoring in mangrove-lined coastal systems. Localities were selected along the Nicaraguan coastline in the rainy and dry seasons during 2012-2013: A. tuberculosa and L. grandis were collected in the Pacific, and P. arctata in the Caribbean. The tissue concentration of metals, polycyclic aromatic hydrocarbons (PAHs) and persistent organic pollutants (POPs) were integrated into pollution indices (chemical pollution index -CPI- and pollution load index -PLI-) and biological endpoints (flesh-condition, reproduction, histopathology and stress-on-stress) were determined as biomarkers of ecosystem health disturbance. In the Caribbean, contaminant tissue concentration was low in P. arctata, with some exceptions. Ag, As, Cd, Hg, Ni and V were mainly recorded during dry season, and PAHs and POPs (HCHs, DDTs, AHTN, PCBs and BDE85) during rainy season. Metals and PAHs were not a major threat in the study area; in contrast, high levels of HCHs and DDTs and low-to-moderate levels of musk fragrances and PBDEs were recorded. Minor differences were found in biological parameters albeit during the rainy season the LT50 values were low and seemingly associated to high PLI and CPI values. In the Pacific, the main pollutants recorded in A. tuberculosa and L. grandis were HCHs, DDTs, AHTN and PDBEs in rainy season and Cd in dry season. Although basic research is needed to understand the general biology, ecology and diseases in these Pacific species, biological endpoints comparable to those used in other sentinel bivalves are seemingly suitable biomarkers of health disturbance. Overall, Caribbean P. arctata and Pacific A. tuberculosa and L. grandis seem to be potential target species for pollution monitoring and ecosystem health disturbance assessment in mangrove-lined Nicaraguan coastal systems. Their use together with C. rhizophorae would provide opportunities for common approaches to be applied in inter-ocean countries of the Mesoamerican region.

Chaillon, Antoine; Avila-Ríos, Santiago; Wertheim, Joel O; Dennis, Ann; García-Morales, Claudia; Tapia-Trejo, Daniela; Mejía-Villatoro, Carlos; Pascale, Juan M; Porras-Cortés, Guillermo; Quant-Durán, Carlos J; Lorenzana, Ivette; Meza, Rita I; Palou, Elsa Y; Manzanero, Marvin; Cedillos, Rolando A; Reyes-Terán, Gustavo; Mehta, Sanjay R
| Idioma(s): Inglés
BACKGROUND: Migration and travel are major drivers of the spread of infectious diseases. Geographic proximity and a common language facilitate travel and migration in Mesoamerica, which in turn could affect the spread of HIV in the region. METHODS: 6092 HIV-1 subtype B partial pol sequences sampled from unique antiretroviral treatment-naïve individuals from Mexico (40.7%), Guatemala (24.4%), Honduras (19%), Panama (8.2%), Nicaragua (5.5%), Belize (1.4%), and El Salvador (0.7%) between 2011 and 2016 were included. Phylogenetic and genetic network analyses were performed to infer putative relationships between HIV sequences. The demographic and geographic associations with clustering were analyzed and viral migration patterns were inferred using the Slatkin-Maddison approach on 100 iterations of random subsets of equal number of sequences per location. RESULTS: A total of 1685/6088 (27.7%) of sequences linked with at least one other sequence, forming 603 putative transmission clusters (range: 2-89 individuals). Clustering individuals were significantly more likely to be younger (median age 29 vs 33years, p<0.01) and men-who-have-sex-with-men (40.4% vs 30.3%, p<0.01). Of the 603 clusters, 30 (5%) included sequences from multiple countries with commonly observed linkages between Mexican and Honduran sequences. Eight of the 603 clusters included >10 individuals, including two comprised exclusively of Guatemalans (52 and 89 individuals). Phylogenetic and migration analyses suggested that the Central and Southern regions of Mexico along with Belize were major sources of HIV throughout the region (p<0.01) with genetic flow southward from Mexico to the other nations of Mesoamerica. We also found evidence of significant viral migration within Mexico. CONCLUSION: International clusters were infrequent, suggesting moderate migration between HIV epidemics of the different Mesoamerican countries. Nevertheless, we observed important sources of transnational HIV spread in the region, including Southern and Central Mexico and Belize.

[Introducción], El Dr. Theodor Fiedrich, Representante de la FAO y la Dra. Vivian Pérez, Consultora de OPS/OMS en Cuba, realizaron la presentación conjunta del más reciente informe del Panorama del Estado de la Seguridad Alimentaria y Nutricional de América Latina y el Caribe, que en esta ocasión se centró en analizar el incremento de la obesidad y el sobrepeso en la región y cómo las políticas agrarias pueden contribuir a mejorar la oferta de alimentos para una nutrición saludable. Según su nuevo informe conjunto, el Panorama de la Seguridad Alimentaria y Nutricional en América Latina y el Caribe, cerca del 58 % de los habitantes de la región vive con sobrepeso (360 millones de personas). Salvo en Haití (38,5%), Paraguay (48,5%) y Nicaragua (49,4%) el sobrepeso afecta a más de la mitad de la población de todos los países de la región, siendo Chile (63%), México (64 %) y Bahamas (69%) los que presentan las tasas más elevadas. La obesidad afecta a 140 millones de personas, el 23% de la población regional y las mayores prevalencias se pueden observar todas en países del Caribe: Bahamas (36,2%) Barbados (31,3%), Trinidad y Tobago (31,1%) y Antigua y Barbuda (30,9%). El aumento de la obesidad ha impactado de manera desproporcionada a las mujeres: en más de 20 países de América Latina y el Caribe, la tasa de obesidad femenina es 10 puntos porcentuales mayores que la de los hombres

OBJECTIVE: To expand the "Countdown to 2015" analyses of health inequalities beyond the 75 countries being monitored worldwide to include all countries in Latin America and the Caribbean (LAC) that have adequate data available. METHODS: Demographic and Health Surveys and Multiple Indicator Cluster Surveys were used to monitor progress in health intervention coverage and inequalities in 13 LAC countries, five of which are included in the Countdown (Bolivia, Brazil, Guatemala, Haiti, and Peru) and eight that are not (Belize, Colombia, Costa Rica, Dominican Republic, Guyana, Honduras, Nicaragua, and Suriname). The outcomes included neonatal and under-5 year mortality rates, child stunting prevalence, and the composite coverage index-a weighted average of eight indicators of coverage in reproductive, maternal, newborn, and child health. The slope index of inequality and concentration index were used to assess absolute and relative inequalities. RESULTS: The composite coverage index showed monotonic patterns over wealth quintiles, with lowest levels in the poorest quintile. Under-5 and neonatal mortality as well as stunting prevalence were highest among the poor. In most countries, intervention coverage increased, while under-5 mortality and stunting prevalence fell most rapidly among the poor, so that inequalities were reduced over time. However, Bolivia, Guatemala, Haiti, Nicaragua, and Peru still show marked inequalities. Brazil has practically eliminated inequalities in stunting. CONCLUSIONS: LAC countries presented substantial progress in terms of reducing inequalities in reproductive, maternal, newborn, and child health interventions, child mortality, and nutrition. However, the poorest 20% of the population in most countries is still lagging behind, and renewed actions are needed to improve equity. OBJETIVO: Extender los análisis de la "Cuenta Regresiva para 2015" de las desigualdades en materia de salud más allá de los 75 países sometidos a vigilancia en todo el mundo para incluir a todos los países de América Latina y el Caribe (ALC) que disponen de datos adecuados. MÉTODOS: Se utilizaron encuestas de demografía y salud y encuestas agrupadas de indicadores múltiples para vigilar el progreso de la cobertura de las intervenciones de salud y de las desigualdades en 13 países de ALC, 5 de ellos incluidos en la Cuenta Regresiva (Bolivia, Brasil, Guatemala, Haití y Perú) y 8 no incluidos (Belice, Colombia, Costa Rica, Guyana, Honduras, Nicaragua, República Dominicana y Suriname). Los resultados incluyeron las tasas de mortalidad neonatal y en menores de 5 años, la prevalencia del retraso del crecimiento en niños y el índice compuesto de cobertura (un promedio ponderado de 8 indicadores de cobertura en materia de salud reproductiva, materna, neonatal e infantil. Para evaluar las desigualdades absolutas y relativas, se emplearon el índice de desigualdad de la pendiente y el índice de concentración. RESULTADOS: El índice compuesto de cobertura mostró patrones monotónicos en función de los quintiles de riqueza, con los niveles más bajos en el quintil más pobre. La mortalidad neonatal y en menores de 5 años, así como la prevalencia del retraso del crecimiento, fueron más elevadas entre los pobres. En la mayor parte de los países aumentó la cobertura de las intervenciones, mientras que la mortalidad en menores de 5 años y la prevalencia del retraso del crecimiento disminuyeron más rápidamente entre los pobres, de manera que las desigualdades se redujeron con el transcurso del tiempo. Sin embargo, en Bolivia, Guatemala, Haití, Nicaragua y Perú aún se observan marcadas desigualdades. Brasil prácticamente ha eliminado las desigualdades en cuanto a retraso del crecimiento. CONCLUSIONES: Los países de ALC mostraron avances considerables en la reducción de las desigualdades con respecto a las intervenciones de salud reproductiva, materna, neonatal e infantil, y en materia de mortalidad y nutrición infantil. Sin embargo, el 20% más pobre de la población en la mayor parte de los países sigue quedándose a la zaga, y son necesarias iniciativas renovadas para mejorar la equidad.

Cruise ships and bush medicine: globalization on the Atlantic Coast of Nicaragua and effects on the health of Creole women.

Mitchell, Emma McKim; Steeves, Richard; Dillingham, Rebecca
| Idioma(s): Inglés
OBJECTIVES: Global health research into the relationship between health, economic inequalities, and globalization is necessary to address increasing health disparities in low income countries. Nicaragua has high levels of poverty and extreme poverty when compared with other Central and South American Countries. DESIGN AND SAMPLE: Photovoice and ethnographic research methods were used to explore health experiences of Creole women in Bluefields, Nicaragua and the intersections between culture, socioeconomic status, and gender. Twelve Creole women participants, ages 18-45. MEASURES: After initial focus groups, participants used disposable cameras to document health experiences. Follow-up interviews were conducted about the meaning of each photo. Participants then selected photos to be included in a city-wide photoshow. RESULTS: In initial focus groups, participants described great distress over changes they perceived in Creole culture and how these changes affect the health of the next generation. Participants related most of these changes to the economy and globalization. Photos taken were primarily of aspects of Creole culture, including household practices and traditional remedies from Creole culture. CONCLUSIONS: Findings on the relationships between culture, disease, and community-identified health risks in this minority population can help health care providers and public health policymakers develop and sustain culturally appropriate health interventions.

The impact of time on predicate forms in the manual modality: signers, homesigners, and silent gesturers.

Goldin-Meadow, Susan
| Idioma(s): Inglés
It is difficult to create spoken forms that can be understood on the spot. But the manual modality, in large part because of its iconic potential, allows us to construct forms that are immediately understood, thus requiring essentially no time to develop. This paper contrasts manual forms for actions produced over three time spans-by silent gesturers who are asked to invent gestures on the spot; by homesigners who have created gesture systems over their life spans; and by signers who have learned a conventional sign language from other signers-and finds that properties of the predicate differ across these time spans. Silent gesturers use location to establish co-reference in the way established sign languages do, but they show little evidence of the segmentation sign languages display in motion forms for manner and path, and little evidence of the finger complexity sign languages display in handshapes in predicates representing events. Homesigners, in contrast, not only use location to establish co-reference but also display segmentation in their motion forms for manner and path and finger complexity in their object handshapes, although they have not yet decreased finger complexity to the levels found in sign languages in their handling handshapes. The manual modality thus allows us to watch language as it grows, offering insight into factors that may have shaped and may continue to shape human language.

Developing a common framework for integrated solid waste management advances in Managua, Nicaragua.

Olley, Jane E; IJgosse, Jeroen; Rudin, Victoria; Alabaster, Graham
| Idioma(s): Inglés
This article describes the municipal solid waste management system in Managua, Nicaragua. It updates an initial profile developed by the authors for the 2010 UN-HABITAT publication Solid Waste Management in the World's Cities and applies the methodology developed in that publication. In recent years, the municipality of Managua has been the beneficiary of a range of international cooperation projects aimed at improving municipal solid waste management in the city. The article describes how these technical assistance and infrastructure investments have changed the municipal solid waste management panorama in the city and analyses the sustainability of these changes. The article concludes that by working closely with the municipal government, the UN-HABITAT project Strengthening Capacities for Solid Waste Management in Managua was able to unite these separate efforts and situate them within a strategic framework to guide the evolution of the municipal solid waste management system in the forthcoming years. The creation of this multi-stakeholder platform allowed for the implementation of joint activities and ensured coherence in the products generated by the different projects. This approach could be replicated in other cities and in other sectors with similar effect. Developing a long term vision was essential for the advancement of municipal solid waste management in the city. Nevertheless, plan implementation may still be undermined by the pressures of the short term municipal administrative government, which emphasize operational over strategic investment.

Treatment and prevention of malnutrition in Latin America: focus on Chile and Bolivia.

Weisstaub, Gerardo; Aguilar, Ana Maria; Uauy, Ricardo
| Idioma(s): Inglés
Seven million children under 5 years of age died worldwide in 2011, and one-third had malnutrition. Latin America and Caribbean countries stand out for the notable improvement of their health and nutrition situation, particularly in pregnant women and young children. Nutrition-sensitive interventions such as promoting food security, women's empowerment, social safety nets, clean water, and sanitation, among others, are critical for success. In Bolivia, the program Desnutrición Cero (Malnutrition Zero) was able to reduce mortality from severe malnutrition after 5 years from 25% to less than 5%, based on widespread implementation of the World Health Organization 10-steps protocol for hospitalized care and the application of community management. The Economic Commission for Latin America estimated the cost of malnutrition for Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, Panama, and the Dominican Republic as US $6,658 million. Approximately 1 million children have dropped out of school because of malnutrition, and as a result, malnourished children have 2 years less schooling, which brings social and economic losses not only to those affected but to society at large. National and international nutrition and food programs developed over the past 50 years have been implemented as integral components of broader strategies of primary healthcare and education, oriented toward preventing deaths and improving the quality of life of low-socioeconomic-status groups. Treating hundreds or thousands of affected children will not solve the global public health problem of malnutrition. Access to adequate amounts of quality foods represents a basic human right and is a necessary precondition for health. In turn, good nutrition and health are prerequisites for human, social, and economic development.

Determinantes sociales de la exclusión a los servicios de salud y a medicamentos en tres países de América Central./ [Social determinants of exclusion from health services and medicines in three Central American countries].

Acuña, Cecilia; Marina, Nelly; Mendoza, Adriana; Emmerick, Isabel Cristina Martins; Luiza, Vera Lucía; Azeredo, Thiago Botelho
| Idioma(s): Español
OBJECTIVE: Examine the social determinants that affect population behavior with regard to the search for and acquisition of medicines, and their relationship to exclusion from health services based on aggregate data from three Central American countries: Guatemala, Honduras, and Nicaragua. METHODS: A descriptive, observational cross-sectional study was conducted by administration of a household survey. The study sample was selected in accordance with the conglomerate method. Data was analyzed with the SPSS® V.17 program using descriptive statistics, bivariate, multivariate, and principal components analysis (PCA). RESULTS: Although the majority of the persons could access health care, health exclusion (odds ratio [OR] 4.10; 95% confidence interval [95% CI]) was the main determinant of lack of access to medicines. The characteristics of housing (OR 0.747, 95% CI), formal employment of head of the household (OR 0.707, 95% CI), and socioeconomic status of the household (OR 0.462, 95% CI) were also important determinants of lack of access to medicines. CONCLUSIONS: The phenomena of lack of access to health services and medicines are not independent from one another. It was corroborated that the health system, as an intermediate social determinant of health, is an important factor for improvement of access to medicines. Public policies that aim to achieve universal coverage should consider this relationship in order to be effective.

| Idioma(s): Español
OBJETIVO: Examinar los determinantes sociales que afectan la conducta de la población en relación con la búsqueda y obtención de medicamentos, y su relación con la exclusión de los servicios de salud para datos agregados de tres países de América Central: Guatemala, Honduras y Nicaragua. MÉTODOS: Estudio observacional descriptivo de corte transversal, mediante la aplicación de una encuesta de hogares. La muestra del estudio se seleccionó de acuerdo al método de conglomerados. Los datos fueron analizados con el programa SPSS® V.17, utilizando estadística descriptiva y análisis bivariado, multivariado y por componentes principales (ACP). RESULTADOS: Aunque la mayoría de las personas pudo acceder a la atención en salud, la exclusión en salud (razón de probabilidades [RP] 4,10; intervalo de confianza de 95% [IC95%]) fue el principal determinante de la falta de acceso a los medicamentos. Las características de la vivienda (RP 0,747, IC95%), la formalidad del empleo del jefe(a) de hogar (RP 0,707, IC95%) y las condiciones socioeconómicas del hogar (RP 0,462, IC95%) fueron también importantes determinantes de la falta de acceso a los medicamentos. CONCLUSIONES: Los fenómenos de la falta de acceso a servicios de salud y a medicamentos no son independientes entre sí. Se corroboró que el sistema de salud, como determinante social intermediario de la salud, es un factor importante para la mejora del acceso a medicamentos. Las políticas públicas orientadas a alcanzar la cobertura universal deben contemplar esta relación para ser eficaces.
