OBJECTIVE: To generate and evaluate an indicator of the health system's performance in the area of maternal and reproductive health in Colombia. MATERIALS AND METHODS: An indicator was constructed based on variables related to the coverage and utilization of healthcare services for pregnant and reproductive-age women. A factor analysis was performed using a polychoric correlation matrix and the states were classified according to the indicator's score. A path analysis was used to evaluate the relationship between the indicator and social determinants, with the maternal mortality ratio as the response variable...

A brief trip to Caquetà and Putumayo prov., South Colombia, during the month of November 2016, allowed us to discover two species new to science. The research was undertaken under the auspices of a joint educational/scientific project with the Apostolic Vicariate of the Consolata Fathers in the department of Putumayo (South Colombia).

The glassfrog genus Cochranella, with nine recognized species, is distributed in the lowlands and mid elevation of the Neotropical forests, from Nicaragua to Bolivia (Guayasamin et al. 2009; Twomey et al. 2014). Four species are trans-Andean-C. granulosa (Taylor 1949) occurs in the lowlands and mountains, at mid elevation, of Central America, C. litoralis (Ruiz-Carranza & Lynch 1996) and C. mache Guayasamin & Bonaccorso 2004 occur in the Pacific lowlands and the western cloud forests of Colombia and Ecuador, and C...

Mercury (Hg) is a global contaminant posing severe risks to human health worldwide. The aim of this study was to assess the levels of total Hg (T-Hg) in human hair and fish in the Caqueta River, at the Colombian Amazon, as well as to determine fish consumption-based risks for T-Hg ingestion. T-Hg levels were measured using a direct mercury analyzer. The overall mean T-Hg level in hair for humans in the Caqueta River sample (n = 200) was 17.29 ± 0.61 μg/g (1.2 to 47.0 μg/g). Ninety-four percent of the individuals had hair T-Hg concentrations greater than the WHO threshold level (5 μg/g), and 79 % displayed levels higher than 10 μg/g...

Colombia has an imposing natural wealth due to its topography has many unique characteristics as a consequence of having Caribbean and Pacific shores, as well as sharing part of the Amazon basin and northern Andes mountains. Thus, many natural and biological features are due to the convergence of three biogeographical regions: Pacific, Andes and Amazonia. The Andean uplift created a complex mosaic of mountains and isolated valleys, including eleven biogeographical provinces (Morrone 2006). The Andes dominate the Colombian topography and cross the country south to north...

Outsiders often oversimplify Amazon soil use by assuming that abundantly available natural soils are poorly suited to agriculture and that sporadic anthropogenic soils are agriculturally productive. Local perceptions about the potentials and limitations of soils probably differ, but information on these perceptions is scarce. We therefore examined how four indigenous communities in the Middle Caquetá River region in the Colombian Amazon classify and use natural and anthropogenic soils. The study was framed in ethnopedology: local classifications, preferences, rankings, and soil uses were recorded through interviews and field observations...
