UNA SALUD / ONE HEALTH
El proyecto UNA SALUD / ONE HEALTH tiene como objetivo la conservación de la biodiversidad, y abarca el concepto holístico de mantener ecosistemas saludables, para obtener animales saludables y proteger la salud publica.
COMIENZOS DEL PROGRAMA UNA SALUD/ ONE HEALTH
En Julio de 2010, se inició una colaboración entre la Fundacion FUCOBI de Ecuador y IMSEGI de USA, para realizar un estudio piloto de los proyectos del programa UNA SALUD/ONE HEALTH en Ecuador. Estudiantes de Boston College, Tufts University, estudiantes de Universidad Técnica de Machala, UPSE, y colegios de New Jersey y Massachussetts se unieron a la expedición científica por un mes a lo largo de la costa Ecuatoriana, recolectando muestras de biodiversidad de manglares, camarones, concha, cangrejo, pescado y otras especies acompañantes del camarón en las cinco provincias costeras del Ecuador (Esmeraldas, Manabí, Santa Elena, Guayas y El Oro). Esto con el objetivo de crear bases de datos que contengan información fenotípica y genotípica de las especies analizar. El programa Una SALUD / ONE HEALTH de Ecuador es parte de la iniciativa internacional IMSEGI dirigida por la Dra. Alcivar-Warren que se enfoca en el tema holístico de “ONE HEALTH: "Conserving healthy ecosystems, to produce and maintain healthy animals, and protect human health long-term" / Conservar Ecosistemas Saludables, para producir y mantener animales saludables y proteger la salud pública a través del tiempo.

En cada uno de los lugares que estuvimos se habló con la gente de las comunidades, dirigentes y representantes de organizaciones no gubernamentales ONGs para conocer la verdadera situación de estos ecosistemas. Además se realizaron análisis bioquímicos de sangre de los pobladores de las comunidades que viven en el manglar para determinar los índices de salud, presencia metales pesados y contaminantes orgánicos persistentes (COPs). Los resultados preliminares se están usando para escribir proyectos a organismos internacionales para financiar el proyecto a largo plazo (2010-2020).

Biodiversity of healthy ecosystems is linked to food security and human health. Trace concentrations of potential endocrine disrupting chemicals (EDCs) such as heavy metals and persistent organic pollutants (POPs) have been reported in shellfish, fish, seawater and sediment from estuarine mangroves of Ecuador. Consumption of POP-containing fish, chlorinated pesticides and polychlorinated biphenyls (PCBs), in particular, has been found strongly linked to the development of metabolic syndrome, insulin resistance, obesity and diabetes type 2. Cadmium (Cd) exposure is also associated with diabetes, chronic kidney disease, and children with adverse neurodevelopmental outcomes such as learning disabilities. To understand the relationship between health status of marine ecosystems and human health, long-term biomonitoring studies are essential to understand the relationship. In 2010, the FUCOBI Foundation launched the UNA SALUD/ONE HEALTH project, a 10-year, integrated holistic program aimed at conserving healthy ecosystems (i.e. mangroves), to maintain healthy animals (shellfish/fish), to protect human health long term. One major goal of the ONE HEALTH project is to catalogue the extension and distribution of species biodiversity both at the taxonomic and molecular level. Analysis of the relationships between biodiversity and the pollutant load in mangrove sediment and local fauna (including humans) will establish associations between seemingly disparate ends of the ecological continuum. We work with local communities, educating them about mangrove conservation and pollution, to maintain healthy local consumer seafood thus protect human health. In 2011 we (1) hosted the "Second International Meeting on UNA SALUD/ONE HEALTH" on June 30, 2011 at the USFQ in Quito, Ecuador with special guest, Dr. Barbara S. Nikolajczyk of Boston University, featuring an outstanding presentation entitled “Do immune system changes explain the link between type 2 diabetes and environmental contaminants?" and offered graduate training opportunities for Ecuadorian students and researchers, and (2) continued collection of samples and performed basic research to establish the FUCOBI's biodiversity and pollutant databases. Other meeting topics included reports on our projects related to the biological, environmental, cultural and economical value of mangrove forests; annotated bibliography on health status, biodiversity and pollutant load of mangroves from Ecuador and worldwide; viral disease prevalence in wild shrimp of Ecuador; the role of transposable elements (Tes) in infectious and non-infectious shrimp viruses, the shrimp genome, evolution of viruses; antibiotic resistance; shrimp genetic diversity; POPs (PCBs, PAHs) in sediment and shrimp, and preliminary results on blood cell counts and chemistry parameters (glucose, uric acid, creatinine, cholesterol, triglycerides) and their potential association with eating habits of 403 people living along the coast of Ecuador. A hypothesis on the potential link between environmental contaminants and the high incidence of congenital malformations and diabetes in the Santa Elena peninsula was also presented.
FUCOBI collaborators, including high school and college students from USA and Ecuador participated in 2011 research activities. These included (a) collection of shrimp samples and accompanying biodiversity in estuarine mangroves, and (b) preparation of comprehensive literature review about the health status of Ecuadorian mangroves in Ecuador including nutrients and contaminants such as heavy metals and POPs in both mangrove plants and sediments worldwide. Sediment contamination levels varied in El Oro and Guayas provinces of Ecuador and are of concern to aquatic species and human health. Mangrove sediment levels of nitrite, nitrate, phosphate and heavy metals varied among and between sites. Phosphate levels in sediment from Bajo Alto, El Oro province were the highest among all sites tested so far. Bajo Alto is located near banana plantations and other agroindustries, and is the same site where UTM professor Cesar Valarezo and his collaborators detected seawater levels of Cd and lead above the accepted limits by the Ministry of the Environment of Ecuador. They found variable metal levels in conch and sediment, some of which are above the maximum allowed levels by national and international agencies and may represent both endocrine and toxicity risk to shrimp and human health. We detected variable levels of ~30 metals in Litopenaeus vannamei shrimp from the five coastal provinces of Ecuador. We are compiling a database on metals and POPs present in human blood and hair. Blood samples from people living along the coast were collected for heavy metals and POP analyses (results pending) and isolation of nucleic acids and proteins for future epidemiological and epigenetics studies.
A brief summary will be presented of on-going review of the literature on the association of environmental contaminants (Cd, POPs) with obesity, insulin resistance and diabetes, the link between dioxin receptor aryl hydrocarbon receptor (AhR) and diabetes/glucose metabolism, the induction of LINE-1 retrotransposon by AhR, the role of Tes in genes involved in the hyperglycemia pathway, and the link between LINE-1 expression and the ligand of AhR. The information will be used to prepare grant proposals in support of our ONE HEALTH goals. Shrimp tissue samples will show species differentiation using mitochondrial (D-loop, 16s rRNA) and nuclear (allergens, LINE-1) DNA markers. These measures will also allow commodity shrimp traceability from shrimp sold in US supermarkets using Parallel Factor Analysis with Soft Independent Modeling of Class Analogy (PARAFAC-SIMCA) scores. We search for polymorphisms in allergy-causing genes to develop a hypoallergenic shrimp line and biomarkers of exposure to high and low levels of pollutants. Information will be presented on FUCOBI’s program for 2012 and welcome the new ONE HEALTH national and international collaborators that will study the role of pollutants (metals and POPs) on the induction of Tes, the potential involvement of these pollutants on immune system changes in people with obesity and diabetes, and the increased incidence of congenital malformations.
