Quinoa is a plant that is cultivated in the Andean highlands across Peru and Bolivia. It is increasingly popular due to its high nutritive value and protein content. In particular, the cultivation of organic quinoa has grown substantially in recent years since it is the most demanded type of quinoa in the foreign market. Nevertheless, despite the interest that quinoa has generated in terms of its nutritional properties, little is known regarding the environmental profile of its production and processing. Therefore, the main objective of this study was to analyze the environmental impacts that are linked to the production and distribution of organic quinoa to the main export destinations through the application of the Life Cycle Assessment (LCA) methodology...

BACKGROUND: Chagas disease (CD) is a systemic parasitic infection caused by the protozoan Trypanosoma cruzi, whose chronic phase may lead to cardiac and intestinal disorders. Endemic in Latin America where it is transmitted mainly by vectors, large-scale migrations to other countries have turned CD into a global health problem because of its alternative transmission routes through blood transfusion, tissue transplantation, or congenital. Aim of this study was to compare the performance of two commercially available tests for serological diagnosis of CD in a group of Latin American migrants living in a non-endemic setting (Rome, Italy)...

The physiology of fatherhood is a growing field of study, and variability in hormonal mediators of reproductive effort (e.g. testosterone, cortisol) can predict variability in paternal investment. Studies often find that lower testosterone levels are associated with increased paternal investment, though most studies are conducted under relatively stable ecological conditions. In this paper, we examine parental physiological correlates of crop loss and family health problems among Tsimane forager-horticulturalists following a catastrophic flood in lowland Bolivia...

BACKGROUND: Unintended pregnancies can result in poorer health outcomes for women, children and families. Young people in low and middle income countries are at particular risk of unintended pregnancies and could benefit from innovative contraceptive interventions. There is growing evidence that interventions delivered by mobile phone can be effective in improving a range of health behaviours. This paper describes the development of a contraceptive behavioural intervention delivered by mobile phone for young people in Tajikistan, Bolivia and Palestine, where unmet need for contraception is high among this group...

INTRODUCTION: Epilepsy represents a major health problem in low- and middle-income countries where treatment gap (TG) levels are high. The reduction of epilepsy TG in the rural area of the Chaco region, Plurinational State of Bolivia, has been the aim of many projects based on the reinforcement of the primary care setting. To plan educational campaigns directed to the healthcare professionals, it is necessary to establish their baseline knowledge level. The objective of our study was to assess the baseline level of knowledge, attitudes, and practices (KAP) towards epilepsy among general practitioners (GPs) of the rural communities of the Chaco region...

Salmonella typhi and Helicobacter infections have been shown to increase risk of gallbladder cancer (GBC), but findings have been inconsistent. Other bacterial infections may also be associated with GBC. However, information on microbial pathogens in gallbladder bile of GBC patients is scarce. We aimed to investigate the microbial communities in gallbladder bile of patients with GBC and cholelithiasis (CL). Seven GBC patients and 30 CL patients were enrolled in this study. Genomic DNA was extracted from bile and the V3-V4 region of 16S rRNA was amplified...

Background: Cutaneous leishmaniasis (CL) is an endemic disease in Bolivia, particularly in the rainforest of Cochabamba, in the municipality of Villa Tunari. The precarious, dispersed, and poorly accessible settlements in these farming communities make it difficult to study them, and there are no epidemiological studies in the area. The aim of the present study was to identify the risk factors associated with cutaneous leishmaniasis. Methods: A cross-sectional study was conducted in August 2015 and August 2016 in two communities of Villa Tunari, Cochabamba...

Current debates in the conservation sciences argue for better integration between research and practice, often citing the importance of the diffusion, dissemination and implementation of scientific knowledge for environmental management and policy. This paper focuses on a relatively well-researched protected area (Madidi National Park) in Bolivia in order to present different interpretations and understandings of the implications and availability of research findings. We draw on findings from quantitative and qualitative methods to determine the extent to which research carried out in the region was disseminated and/or implemented for management actions, and to understand subsequent implications for how local actors perceive the value of research and its role in management and conservation...

In recent decades, major advances in the systematics of the Western Hemisphere genus Paracloeodes Day have been made in South America. Despite the taxonomic progress, uncertainties in identification remain due to the morphological similarities among some nymphs and due to the general lack of knowledge of the imago stages (only 4 of 20 are described from throughout the range of the genus). This study addresses these impediments in part through description of the male imagoes of six species (P. atroari Nieto Salles, P...

Banded Knifefishes (Gymnotus, Gymnotidae) comprise the most species-rich genus of Neotropical electric fishes, with 41 species currently described from throughout the humid Neotropics, from Mexico to Argentina. Despite substantial alpha-taxonomic work in recent years, the diversity of Gymnotus in some regions remains poorly understood. Here we describe the Gymnotus fauna of the Upper Madeira basin of Bolivia and Peru from examination of more than 240 adult specimens. Species are delimited and described using body proportions (traditional morphometrics), fin-ray, squamation and laterosensory-pore counts (meristics), quantitative shape differences (geometric morphometrics), osteological traits, and color patterns...

To date, the subgenus Rhomboconnus Franz of Euconnus Thomson was represented by ten species known to occur in Venezuela, Panama and Ecuador. For the first time Rhomboconnus is reported to occur in Peru and Bolivia, and two new species are described: Euconnus wari sp. n. (Peru) and E. inkachakanus sp. n. (Bolivia). The latter species is the largest representative of Rhomboconnus, with body length exceeding 3 mm.

Dendropsophus cruzi (Pombal Bastos, 1998) is a small hylid (male snout-to-vent length = 16.3-19.4 mm; female SVL = 21.3-25.0 mm) that is allocated in the D. microcephalus group (Faivovich et al. 2005). It is commonly found in Open and forested areas from Central Brazil to Provincia Velasco, Departamento de Santa Cruz, Bolivia (Frost 2017; Tessarolo et al. 2016). Pombal Bastos (1998) described the advertisement call of D. cruzi as a single pulsed note. Posteriorly, studies uncovered relationships between dominant frequency variation in the advertisement calls of D...

Intensive survey of museum collections and new field collecting resulted in discovery of six new, closely related species of the Neotropical Merophysiinae. A new species of the genus Lycoperdinella Champion, L. boliviensis sp. n ., from Bolivia and Brazil, and five new species from Mexico for which a new genus is proposed here as Rueckeria gen. n .: R. inecol (type species), R. nigrileonis , R. ocelotl , R. puma , R. skelleyi spp. n ., have been discovered. Lycoperdinella , Rueckeria gen. n ., L. subcaeca Champion and all new species are diagnosed, described, and illustrated...

Compared with mice, adult rats living at 3,600 m above sea level (SL-La Paz, Bolivia) have high hematocrit, signs of pulmonary hypertension, and low lung volume with reduced alveolar surface area. This phenotype is associated with chronic mountain sickness in humans living at high altitude (HA). We tested the hypothesis that this phenotype is associated with impaired gas exchange and oxidative stress in the lungs. We used rats and mice (3 months old) living at HA (La Paz) and SL (Quebec City, Canada) to measure arterial oxygen saturation under graded levels of hypoxia (by pulse oximetry), the alveolar surface area in lung slices and the activity of pro- (NADPH and xanthine oxidases-NOX and XO) and anti- (superoxide dismutase, and glutathione peroxidase-SOD and GPx) oxidant enzymes in cytosolic and mitochondrial lung protein extracts...
