Mercury Exposure in Women of Reproductive Age in Rondônia State, Amazon Region, Brazil
Environmental contamination by mercury (Hg) is a problem of global scale that affects human health. This study's aim was to evaluate Hg exposure among women of reproductive age residing in the Madeira River basin, in the State of Rondônia, Brazilian Amazon. This longitudinal cohort study used linear regression models to assess the effects on Hg levels of breastfeeding duration at 6 months, and of breastfeeding duration and number of new children …
Our evolved understanding of the human health risks of mercury
Mercury (Hg) is a chemical of health concern worldwide that is now being acted upon through the Minamata Convention. Operationalizing the Convention and tracking its effectiveness requires empathy of the diversity and variation of mercury exposure and risk in populations worldwide. As part of the health plenary for the 15th International Conference on Mercury as a Global Pollutant (ICMGP), this review paper details how scientific understandings h…
Intestinal Parasites, Anemia and Nutritional Status in Young Children from Transitioning Western Amazon
Young children are particularly vulnerable to the chronic sequelae of anemia, including poor nutritional status. The aim of this study was to assess intestinal parasitic-infections and nutritional status (anemia and linear growth) in preschool children living in contemporary Amazonian communities. A cross-sectional study measured children's intestinal parasites and hair-Hg (HHg)-biomarkers of fish consumption, hemoglobin levels, and growth (anthr…
Mapping the Evolution of Mercury (Hg) Research in the Amazon (1991–2017)
Because the Amazon rain forest is ecologically relevant on a global scale, we applied scientometric techniques to integrate studies dealing with mercury research in this unique ecosystem between 1991 and 2017. Using a combination of co-authorship and co-citation analyses, keyword mapping and overlay visualization of topics in the field, this article identified three major areas in the 26-year period of mercury research: (1) human exposure to merc…
Adverse Events Following Immunization in Brazil
Objective : Vaccines are effective in controlling and eradicating infectious diseases. However, adverse events following immunization (AEFI) can occur in susceptible individuals. The objective of this study was to analyze the Brazilian AEFI database and compare eight vaccines in order to profile risks of AEFIs related to the mandated pediatric schedule of immunization, considering the age and sex of the child, type of vaccine, and reported advers…
Judicialização de eventos adversos pós-vacinação
A ciência trouxe importantes contribuições para a melhoria do bem-estar do ser humano, surpreendendo com criações que buscam protegê-lo das enfermidades. Vacinas são exemplo, funcionando como instrumentos de melhoria de vida da população mundial. Entretanto, vacinas apresentam riscos cujas consequências não são completamente conhecidas, sendo importante a presença de sistemas de vigilância que neutralizem ou diminuam os eventos adversos delas pro…
Mercury levels and human health in the Amazon Basin
CONTEXT: Environmental mercury in the Amazon mostly originates from geochemical sources with some from artisanal gold mining (AGM). Geochemical-originated methylmercury (MeHg) reaches the aquatic food chain, ending up in fish. Inorganic Hg used in AGM is responsible for localised environmental contamination and occupational exposure of adults. In addition to this, iatrogenic ethylmercury (EtHg) derived from Thimerosal-containing vaccines (TCVs) e…
Traditional living in the Amazon
HHg increased in children and decreased in mothers at 24 months. Frequency of fish consumption was significantly correlated with maternal HHg at birth (Spearman's r = 0.8583; p = 0.0001); likewise, there was a significant correlation between duration of breastfeeding and children's HHg (Spearman's r = 0.15; p = 0.0018). Extended breastfeeding did not influence the Mental Development Index-MDI or Psychomotor Development Index-PDI, but maternal edu…
The Influence of Changes in Lifestyle and Mercury Exposure in Riverine Populations of the Madeira River (Amazon Basin) near a Hydroelectric Project
In the Amazon Basin, naturally occurring methylmercury bioaccumulates in fish, which is a key source of protein consumed by riverine populations. The hydroelectric power-plant project at Santo Antônio Falls allows us to compare the Hg exposure of riverine populations sparsely distributed on both sides of the Madeira river before the area is to be flooded. From 2009 to 2011, we concluded a population survey of the area (N = 2,008; representing cir…
Fish Consumption during Pregnancy, Mercury Transfer, and Birth Weight along the Madeira River Basin in Amazonia
Maternal HHg is an important biomarker of maternal fish consumption and of methylmercury exposure during pregnancy. However, in these Amazonian groups, only maternal education and gestational age seemed to affect birth weight positively
Association of Moderate Coffee Intake with Self-Reported Diabetes among Urban Brazilians
Coffee has been associated with reductions in the risk of non-communicable chronic diseases (NCCD), including diabetes mellitus. Because differences in food habits are recognizable modifying factors in the epidemiology of diabetes, we studied the association of coffee consumption with type-2 diabetes in a sample of the adult population of the Federal District, Brazil. This cross-sectional study was conducted by telephone interview (n = 1,440). A …
Toxic Metals (Pb and Cd) and Their Respective Antagonists (Ca and Zn) in Infant Formulas and Milk Marketed in Brasilia, Brazil
In non-ideal scenarios involving partial or non-breastfeeding, cow's milk-based dairy products are mainstream in infant feeding. Therefore, it is important to study the concentrations of potentially neurotoxic contaminants (Pb and Cd) and their respective counteracting elements (Ca and Zn) in infant dairy products. Fifty-five brands of infant formulas and milk sold in Brasilia, Brazil were analyzed. The dairy products came from areas in the centr…
Research into Mercury Exposure and Health Education in Subsistence Fish-Eating Communities of the Amazon Basin
The neurotoxic effects of fish-methylmercury (meHg) consumed regularly are considered hazardous to fetuses and newborn infants; as a result fish consumption advisories are an important asset to control meHg exposure in affluent societies. These concerns are now part of health promotion programs for Amazon subsistence villagers. While urban dwellers in affluent societies can choose an alternative nutritious diet, traditional and subsistence commun…
Fish consumption by traditional subsistence villagers of the Rio Madeira (Amazon)
In Amazonian lifestyle of ribeirinho communities traditional fish consumption is high and depends on available species; fish is also the principal via of meHg exposure and attendant hair-Hg concentrations
Hydroelectric reservoir inundation (Rio Madeira Basin, Amazon) and changes in traditional lifestyle
The study showed that the families' shift in fish consumption had no negative impact on the growth of young children and that ensuing methylmercury exposure has not been a noticeable neurodevelopmental hindrance
Maternal fish consumption in the nutrition transition of the Amazon Basin
The apparently good nutritional status of subjects is more likely due to a well balanced diet composition than to only one dietary protein source--fish
Fish consumption (Hair Mercury) and nutritional status of Amazonian Amer-Indian Children
Fish are abundant and important dietary items for the Amer-Indians, and total hair-Hg (HHg) concentration is a reliable marker of fish consumption. We studied the impact of fish consumption (HHg) on the nutritional status of Indian children of Eastern Amazonia. Weight-for-height Z score (WHZ) was measured, and HHg was determined in 203 children younger than 10 years of age in three villages. There was significantly higher fish consumption in Kaya…
The composition of breast‐ and bottle‐milks fed to poor urban infants
Despite the importance of breast‐milk over bottle‐milks for infants of lower socio‐economic status of less developed countries, few studies have been conducted to examine the differences in composition between these milks as fed to the infant. The calorific constituents of breast‐ and bottle‐milks fed to 133 infants under one year of age were studied cross‐sectionally in a poor urban settlement in Brasilia. Mean energy density of breast‐milk was …
Nutritional status and zinc nutriture in infants and children in a poor urban community of Brazil
A nutritional status study of 146 children, 1 to 12 years old, in a poor urban community of Brazil showed that 27 percent had moderate or severe malnutrition Low hair zinc levels (<70 μg/g) were found in 5.5 percent of the sample and in seven of eight cases these were infants ≤2 years. Mean (±S.D.) hair zinc level of 83 pre‐school children, 136 ± 53 ; μg/g was significantly lower than that of 63 school children, 156 ± 39 μg/g. Color had a signifi…
