    Background notes by the U.S. States Department on the landlocked country of Bolivia, in the center of South America are presented. Bolivia has 6.25 million persons, about 1/3 each of Aymara indians, Quechua indians and mixed races. The growth rate is 2.6%, despite high death rates: infant mortality is 123/1000 and life expectancy is 49 years. There are fertile tropical lowland climate, hills and valleys, high plateaus and very high, dry cold mountain regions. Bolivia is the least developed, poorest nation in South America (per capita income is $536). There are remarkable cultural resources in archaeology, art, music, folklore and crafts, however. The country is plagued with military coups, social unrest, debt, poverty, and the disruption of international traffic in illegal drugs. One of the major resources, tin, has been lost as income due to collapse in tin prices in 1985. Other resources include natural gas, zinc, silver, tungsten, coffee, and undeveloped lithium, potassium and borax. Bolivia has had difficulties with border disputes with Chile, and since 1980, with many former friendly nations, including the U.S. due to a repressive military dictatorship. Recently, a more moderate government came into power, and relations and economic aid have resumed.

    Polojentsev, Dmitry D.; Zalles, R.

    1. An astronomical expedition from Pulkovo observatory in Bolivia, near Tarija was organized in 1982. The first telscope was an astrograph ( D=23 cm, F=230 cm, field = 5x5 degrees ). Sucsessful observations on this instrument are still being made. In all 7 astronomical instuments were installed. Now they are the National Bolivian Observatory. 2. The main results of astrophysical investigations were devoted to 4-color photometry of supernova 1987A and the creation of a Spectrophotometric Catalogue of 60 Selected Southern Stars. 3. The main results of astrometrical investigations were made on two catalogue problems: Photographical Catalogue for Southern Star (FOCAT-S) and Equatorial Catalogue (ECAT). The first was the foundation for southern part of PPM Catalogue. 4. A time Service was organized in 1988 in Tarija at the National Astronomical Observatory "Santa Ana". In 1997 Pulkovo observatory assisted to reconstract it. 5. The only Planetarium in Bolivia "Max Schreider"in La Paz was founded in 1976. 6. The Associacion Boliviana de Astronomia (ABA) was organized in 1969 in accordance with a Goverment Resolution. It has branches in Potosy, Santa Cruz, Sucre, Tarija etc. 7. The development of the astronomy in Bolivia depends directly on cooperation with the astronomically developed countries.

  6. Radiation protection in Bolivia

    2001-01-01

    Radiation protection in Bolivia has gone through a number of stages. Initially, in the 1970s, the focus was mainly on the analysis of environmental sources resulting from the nuclear tests carried out by France in the Pacific Ocean. Subsequently, the focus switched somewhat to radiation protection in connection with the mining of uranium and in the area of public health. During the third stage, radiation protection in other areas became important as the use of radiation sources was introduced. Finally, during the present -- fourth -- stage, radiation protection regulations are being introduced and mechanisms for the control of radiation sources are being established. (author)

  8. Bolivia: A Gasified Democracy

    Directory of Open Access Journals (Sweden)

    2004-04-01

    Full Text Available In October 2003 a wave of popular protest  brought down the Sánchez de Lozada government  in Bolivia. The intention to export natural gas to  the United States and Mexico triggered the protests, but actually stood for widespread discontent  with the Sánchez de Lozada government, the  preceding governments and the economic policies  pursued since 1985. The events belie the opinion  of various students of the Latin American democratic transitions who held that Bolivian democracy  was on its way towards consolidation and suggest that the recent inquiries into the quality of Latin  American democracies may point a way ahead in  rethinking democracy in the region. Taking such  assessments as a reference, this article reviews the  ‘gas war’ and looks at the Bolivian political regime as it has functioned over the past decades. It  will be argued that the ‘pacted democracy’, that  until now sustained institutionality, and the economic model adopted in 1985 have excluded an  important part of the population, both in political terms and where poverty alleviation and equity is  concerned. Increasing popular protest has been  met with increasing repression, which gradually  turned Bolivia into a ‘democradura’, or a ‘gasified  democracy’ that relies on teargas and bullets to  uphold itself. At present the country finds itself at  a crossroads. It either may reinvent democracy or  become an institutionalized ‘democradura’. Resumen: Bolivia: una democracia gasificadaEn octubre de 2003 una ola de protesta popular  llevó a la caída del gobierno de Sánchez de Lozada en Bolivia. La intención de exportar gas natural a los Estados Unidos y México gatilló dichas  protestas, aunque en realidad reflejaron un descontento general con el gobierno Sánchez de  Lozada, los gobiernos anteriores y las políticas  económicas implementadas desde 1985.

  11. Iturralde Crater, Bolivia

    Science.gov (United States)

    2002-01-01

    NASA scientists will venture into an isolated part of the Bolivian Amazon to try and uncover the origin of a 5 mile (8 kilometer) diameter crater there known as the Iturralde Crater. Traveling to this inhospitable forest setting, the Iturralde Crater Expedition 2002 will seek to determine if the unusual circular crater was created by a meteor or comet. Organized by Dr. Peter Wasilewski of NASA's Goddard Space Flight Center, Greenbelt, Md., the Iturralde Crater Expedition 2002 will be led by Dr. Tim Killeen of Conservation International, which is based in Bolivia. Killeen will be assisted by Dr. Compton Tucker of Goddard. The team intends to collect and analyze rocks and soil, look for glass particles that develop from meteor impacts and study magnetic properties in the area to determine if the Iturralde site was indeed created by a meteor.This image was acquired on June 29, 2001 by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA's Terra satellite. With its 14 spectral bands from the visible to the thermal infrared wavelength region, and its high spatial resolution of 15 to 90 meters (about 50 to 300 feet), ASTER will image Earth for the next 6 years to map and monitor the changing surface of our planet.ASTER is one of five Earth-observing instruments launched December 18, 1999, on NASA's Terra satellite. The instrument was built by Japan's Ministry of Economy, Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and the data products.The broad spectral coverage and high spectral resolution of ASTER will provide scientists in numerous disciplines with critical information for surface mapping, and monitoring dynamic conditions and temporal change. Example applications are: monitoring glacial advances and retreats; monitoring potentially active volcanoes; identifying crop stress; determining cloud morphology and physical properties; wetlands evaluation; thermal pollution

    The oil and gas industry in Bolivia is discussed. Typically, the hydrocarbon production of the Bolivian fields is made up of very light oil and natural gas, both of very good quality with no deleterious contaminants. About 80% of the production comes from gas condensate fields. At present, the proven gas reserves are more than 6 trillion cubic feet that have been available for the last 10 years, notwithstanding the fact that 200 million cubic feet per day are exported.

  3. The TIPNIS Conflict in Bolivia

    Directory of Open Access Journals (Sweden)

    Ana Carolina Delgado

    Full Text Available Abstract Soon after the formation of the Plurinational State of Bolivia in 2009, the Isiboro Sécure National Park and Indigenous Territory (TIPNIS became the epicentre of a conflict over the construction of a road, initiated by Evo Morales’s administration, that would run through the park. Initially undertaken by the Brazilian company OAS, and funded by the Brazilian Development Bank (BNDES, the project was justified on the grounds that it would link the departments of Beni and Cochabamba, and bring development to an isolated locality. However, indigenous peoples from the lowlands opposed the scheme, and, together with their counterparts in the Andean region, organised a march that was violently dispersed by the Bolivian armed forces. In this article, I analyse the political processes in this Andean country, notably the reconfiguration of power from 2011 onwards, in parallel with economic measures adopted by the government. I conclude with observations about the relation between the national and regional spheres, arguing that indigenous repression forms part of a new developmentalist agenda.

    In Bolivia, the Hispanic dual surname system is used. To describe the isonymic structure of Bolivia, the surname distribution of 12,139,448 persons registered in the 2006 census data was studied in 9 districts and 112 provinces of the nation, for a total of 23,244,064 surnames. The number of different surnames found was 174,922. Matrices of isonymic distances between the administrative units (districts and provinces) were constructed and tested for correlation with geographic distance. In the 112 provinces, isonymic distances were correlated with geographic distance (r = 0.545 ± 0.011 for Euclidean, 0.501 ± 0.012 for Nei's, and 0.556 ± 0.010 for Lasker's distance). The multiple regression of the surname effective number (α), equivalent to the allele effective number in a genetic system, was nonsignificant on latitude and longitude; however, it was highly significant and negative on altitude (r = -0.72). Because the Andes extend from north to south in west-central Bolivia, random inbreeding was lowest in the eastern districts, and highest in mountainous western Bolivia. Average α for the provinces was 122 ± 2; for the districts, it was 216 ± 29, and for the whole of Bolivia it was 213. The geographical distribution of α in the provinces is compatible with the settlement of subsequent groups of migrants moving from east and north toward the center and south of Bolivia. The relative frequency of indigenous surnames is correlated positively with altitude. This suggests that the country was populated by recent low-density demic diffusion over a low-density indigenous population. This may have been a common phenomenon in the immigration to tropical South America. 2010 Wiley-Liss, Inc.

    Started in 2011, the GeoBolivia project (www.geo.gob.bo)aims at building the Spatial Data Infrastructure of the Plurinational State of Bolivia (IDE-EPB by its Spanish initials), as an effort of the Vice Presidency of the State to give an open access to the public geographic information of Bolivia. The first phase of the project has already been completed. It consisted in implementing an infrastructure and a geoportal for accessing the geographic information through WMS, WFS, WCS and CSW services. The project is currently in its second phase dedicated to decentralizing the structure of IDE-EPB and promoting its use throughout the Bolivian State. The whole platform uses free software and open standards. As a complement, an on-line training module was developed to undertake the transfer of the knowledge the project generated. The main software components used in the SDI are: gvSIG, QGis, uDig as GIS desktop clients; PostGreSQL and PostGIS as geographic database management system; geOrchestra as a framework containing the GeoServer map server, the GeoNetwork catalog server and the OpenLayers and Mapfish GIS webclient; MapServer as a map server for generating OpenStreetMap tiles; Debian as operating system; Apache and Tomcat as web servers. Keywords: SDI, Bolivia, GIS, free software, catalog, gvSIG, QGIS, uDig, geOrchestra, OpenLayers, Mapfish, GeoNetwork, MapServer, GeoServer, OGC, WFS, WMS, WCS, CSW, WMC.

  5. Market brief : the oil and gas market in Bolivia

    Energy Technology Data Exchange (ETDEWEB)

    NONE

    2004-03-01

    This report presents a market overview of the oil and gas sector in Bolivia and describes the potential for Canadian suppliers to enter into joint ventures to establish local production facilities and transfer technology expertise. Bolivia has an estimated 54.9 trillion cubic feet of natural gas reserves and 440.5 million barrels of proven oil reserves. The main hope for future economic growth in Bolivia hinges on increasing natural gas exports. Opportunities for Canadian companies exist in exploration, production and pipeline construction. There is also a demand for drilling machinery equipment, pipeline components and services for the expansion of the proposed Bolivia-Brazil pipeline. The largest energy company in Bolivia is Repsol YPF which operates through its subsidiary Empress Petrolera Andina. The largest end-users of oil and gas equipment and services include domestic upstream operators and international oil majors and international exploration and production companies. This report describes the key factors shaping market growth along with the competitive environment, local capabilities, international competition and the Canadian position. Considerations for market-entry in Bolivia were also outlined.

    à quelque Bradyodonte primitif. Les Actinoptérygiens ne sont représentés que par quelques écailles isolées, du Dévonien terminal, et qui évoquent le genre Moythomasia Les restes de Vertébrés les plus abondants dans les nodules du Dévonien de Bolivie sont d'étranges éléments osseux en forme de flûte de Pan qui sont ici attribués au genre Zamponiopteron n.g. Ces éléments, qui n'ont jamais été signalés ailleurs qu'en Bolivie, peuvent être interprétés comme des nageoires paires ankylosées de quelque Chondrichthyen inconnu Trois espèces ont été reconnues dans ce genre, mais elles correspondent seulement à des types morphologiques et il n'y a aucune certitude quant à leur appartenance à des espèces biologiques différentes. Toute conclusion générale d'ordre paléobiogéographique concernant cette faune serait prématurée Cependant, on doit noter qu'elle comprend un mélange de formes à vaste répartition (Rhénanides, quelques Acanthodiens, Actinoptérygiens de type Moythomasia, des formes dont les affinités sont transpacifiques (Acanthodiens proches de Sinacanthus et des formes peut-être endémiques (Pucapampella, Zamponiopteron.

    The family Picornaviridae is a large and diverse group of viruses that infect humans and animals. Picornaviruses are among the most common infections of humans and cause a wide spectrum of acute human disease. This study began as an investigation of acute flaccid paralysis (AFP) in a small area of eastern Bolivia, where surveillance had identified a persistently high AFP rate in children. Stools were collected and diagnostic studies ruled out poliovirus. We tested stool specimens from 51 AFP cases and 34 healthy household or community contacts collected during 2002–2003 using real-time and semi-nested RT-PCR assays for enterovirus, parechovirus, cardiovirus, kobuvirus, salivirus, and cosavirus. Anecdotal reports suggested a temporal association with neurologic disease in domestic pigs, so six porcine stools were also collected and tested with the same set of assays, with the addition of an assay for porcine teschovirus. A total of 126 picornaviruses were detected in 73 of 85 human individuals, consisting of 53 different picornavirus types encompassing five genera (all except Kobuvirus). All six porcine stools contained porcine and/or human picornaviruses. No single virus, or combination of viruses, specifically correlated with AFP; however, the study revealed a surprising complexity of enteric picornaviruses in a single community. PMID:23804569

  9. Plasmodium vivax malaria during pregnancy, Bolivia.

    2013-10-01

    Plasmodium vivax is a major cause of illness in areas with low transmission of malaria in Latin America, Asia, and the Horn of Africa. However, pregnancy-associated malaria remains poorly characterized in such areas. Using a hospital-based survey of women giving birth and an antenatal survey, we assessed the prevalence rates of Plasmodium spp. infections in pregnant women in Bolivia, and evaluated the consequences of malaria during pregnancy on the health of mothers and newborns. P. vivax infection was detected in 7.9% of pregnant women attending antenatal visits, and placental infection occurred in 2.8% of deliveries; these rates did not vary with parity. Forty-two percent of all P. vivax malaria episodes were symptomatic. P. vivax-infected pregnant women were frequently anemic (6.5%) and delivered babies of reduced birthweight. P. vivax infections during pregnancy are clearly associated with serious adverse outcomes and should be considered in prevention strategies of pregnancy-associated malaria.

  10. The oil and gas equipment and services market in Bolivia

    International Nuclear Information System (INIS)

    2003-01-01

    The economy of Bolivia is based mainly on agriculture and resource extraction, making Bolivia one of the poorest countries in Latin America. Approximately 14 per cent of exports are hydrocarbons. Starting in 1996, the oil and gas sector was privatised, resulting in the domination of multinational corporations. It is estimated that the natural gas reserves of Bolivia stand in excess of 2.2 trillion cubic metres. Equipment, materials, and services used in all stages of the oil and gas production and distribution chain are all in demand in Bolivia. Over the medium term, it is expected that pipelines and equipment required for gas-fired power plants represent the most important opportunity in the country. Incentives for vehicle and industrial conversion were included in the new domestic energy plan, as well as the extension of the domestic gas distribution system to 250,000 homes. Canadian geomatics capability could fill the requirements concerning the Bolivian oil and gas assets still in the exploration, development, and documentation stages. Companies with exploration and development contracts, companies producing from commercial fields, refinery operators, producers in the liquid propane gas and compressed natural gas sub-sector, as well as pipeline operators are all considered key players, in addition to the Bolivian Chamber of Hydrocarbons. The customers are sophisticated buyers who purchase based on technical specifications and price negotiations. There are no significant non-tariff barriers, and Bolivia has adopted liberal trade policies. 9 refs., 3 tabs

  12. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Bolivia

    International Nuclear Information System (INIS)

    1977-08-01

    Bolivia has an area of 1,098,580 square kilometers. Its capital is La Paz. The western part of the country is dominated by two ranges of the Andes Mountains, the Cordillera Occidental on the vest flank of the high plateau (Altiplano) and the Cordillera Real (or Oriental) on the east flank. The northern Andes average 5,486 meters in elevation; the southern Andes are not as lofty. The Altiplano is 3,658 to A,267 meters high and 129 km. in average width; it is the largest basin of inland drainage in South America and contains the renowned Lake Titicaca on the Peruvian-Bolivian border. The eastern tropical lowlands or pampas (Oriente) comprise about two-thirds of the country, with rain forest in the northern portion. An intermediate zone of valleys and basins lies between the eastern Andes and Oriente. Bolivia differs from other Andean countries, like Chile, Peru and Ecuador, in having large areas of Preeambrian schists, gneisses, migmatites and granites. These crop out in the eastern part of the country. Parts of these rocks contain banded iron formations (i.e., in the Muttin region) and are probably early Precambrian in age. Little systematic exploration for uranium was undertaken in Bolivia until the late 1960's. In 1967, 1968 and 1969 technical assistance was requested from, and provided by, the IAEA. This work led to evaluation of radioactive anomalies in veins of northeast Bolivia and in sandstones in the extreme southern part of the country. Although no uranium reserves are now credited to Bolivia, the geologic possibilities for several kinds of uranium deposits coupled with the relatively limited work done to date suggest that uranium orebodies will be discovered. It is estimated that the potential resources of Bolivia are in the range of 10,000 to 100,000 tonnes uranium

  13. The Decolonization of Bolivia's Antinarcotics Policy?

    Directory of Open Access Journals (Sweden)

    Alba Hesselroth

    2016-03-01

    Este artículo sostiene que, en el siglo XX, se desarrolló una forma peculiar de colonización en la política antinarcótica de Bolivia, compuesta por rasgos parecidos a los del colonialismo externo e interno. Por una parte, las instituciones internacionales y los Estados Unidos lograron imponer en el país un sistema de control y prohibición del cultivo y consumo de la hoja de coca. Por otra parte,  la élite gobernante apoyada por los EE.UU. impuso su poder y dominio sobre los cocaleros al introducir esta prohibición  y promover la erradicación forzosa de la coca con el auspicio de EE.UU., poniendo en severo peligro los derechos de los  cocaleros. A diferencia de anteriores gobiernos que aceptaron pasivamente las decisiones tomadas en foros internacionales acerca de la clasificación de la hoja de coca como droga ilegal y siguieron con rigor las instrucciones de los EE.UU. acerca de la erradicación de la coca, el gobierno de Evo Morales está actuando para cambiar la situación  en un doble esfuerzo internacional y nacional. Analizando las políticas de este gobierno entre 2006-2014, este artículo sostiene que en el manejo de la política antinarcótica está siguiendo un proceso particular de descolonización para defender los usos tradicionales de la hoja de coca y proteger los derechos sociales, económicos y culturales de las poblaciones andinas involucradas en su producción y/o consumo, y promover el desarrollo económico de las áreas donde se cultiva.

    2014-01-01

    Neural Tube Defects (NTD) are the second congenital malformation, second only to cardiac malformations. Myelomeningocele (MMCL) is the most frequent NTD and the more complex. In Bolivia, like in many countries in South America, the low socio economical level of the population increases its incidences and complicates its management. Retrospective study of 70 cases of MMC at Hospital Universitario Japonés (HUJ), Santa Cruz de la Sierra, between 2008-2011. Sixty had surgery. Prenatal care in 27 women (38.6%), positive diagnosis for spinal disraphism in 2 (7.4%). The child arrived after 24 hours of birth (65.5%). Lumbosacral lesion (64.3%). Of those 67.2% were open, with 32.9% evidencing partial motor lesion in contrast with 47.1% who were paraplegic bellow the level of the lesion. Three children were not operated because they had complex and severe malformations associated to the MMCL. The most common surgical complications were; wound dehiscence or infection (16.6%), CSF fistula (10%) CNS infection (11.7%). Mortality and specifically postoperative mortality were 7.1% y 3.3%, respectively. Hydrocephalus wass evident in 80% of the patients who were operated, they received a VP shunt medium pressure. Nine patients who had long term follow up presented with tethered cord. A characteristic, delayed referral. No gender predominance. Majority of cases were lumbar or lumbar sacral. Mortality similar to what is reported in the literature. Few patients came for follow up. MMCL is a pathology that requires concentrated attention by the national authorities. A multi center and multi national study will improve our management of these patients.

    2012-08-02

    The aim of this study was to document the types of diseases treated by the use of medicinal plants, their main applications and also to have a report of the major diseases treated at the Hospital of San Pablo de Huacareta (Chuquisaca Bolivia). We conducted semi-structured interviews on the use medicinal plants with 10 local informants, and categorized the kinds of diseases treated by traditional medicine. We obtained reports of cases treated at the Hospital of Huacareta in order to compare the use frequency of traditional medicine and allopathic medicine for the treatment of recurrent diseases in the area. Our survey identified 258 traditional medicine uses, spanning a total of 13 diseases categories and including 91 native and exotic plant species and one unidentified sample plant type. Gastrointestinal disorders (55%) were most frequently treated with medicinal plants, followed by afflictions of the musculoskeletal system (25%) and dermatological disorders (24%). Hospital information indicates that the most common diseases are acute respiratory infections (47%) and acute diarrheal diseases (37%). The herbal remedies were mostly used in the form of teas and decoctions. The informants used mainly native plant species, although exotic species has been introduced to the pharmacopoeia. The treatment of gastrointestinal disorders is the primary objective of the medical ethnobotany of the inhabitants of Huacareta, while respiratory system diseases are mostly treated in the hospital. Looking at the data from the Hospital records we can infer that gastrointestinal disorders are among the most common diseases in the study area. For most respondents, traditional medicine is a reliable choice for the care of their illnesses. However, the preference of the population for either traditional medicine or allopathic medicine needs to be clarified in future comparative studies to obtain more convincing results. The results presented can be used as a base for subsequent work

    1999-10-01

    Bolivia, with its large oil and natural gas potential, is becoming an increasingly important link in South American energy trade. With new fields and pipeline construction, the nation is becoming the natural gas hub for the Southern Cone. In 1998, Bolivia experienced 4,7% GDP growth, the fastest in South America, and Bolivia's best performance since 1988. In addition, Bolivia brought its inflation rate to a 2-decade low of 4,4 %. In addition to tight global capital markets, investments also is expected to decrease due to the completion of the Bolivia to Brazil gas pipeline. This extremely capital-intensive project accounted for a significant portion of Bolivia's investment for 1998 and 1999. Bolivia has made significant economic improvements over the past few years by adopting a series of free market policies. The mayor improvements in economic growth have been made possible primarily through the government's unique capitalization program of key national industries. In addition to the Capitalization Program, Bolivia's economic growth is a result of its involvement in several free trade associations. Bolivia, as well as Chile, is an associate partner of the Mercosur, whose members include Argentina, Brazil, Paraguay and Uruguay. Bolivia is also member of the Andean Pact, which comprises Peru, Colombia, Ecuador and Venezuela. Bolivia's unique involvement in both of these trade groups is allowing it to become an important cornerstone in the integration of the South American continent. Specifically, Bolivia is increasingly becoming an important transport hub within the continent. Energy is one of the main products Bolivia is attempting to transport. According to the government, nearly $5 billion of investment is needed by 2005 so Bolivia can succesfully develop its oil and gas reserves, build pipelines, and construct power plants if it wishes to emerge as the regional hub

Results Our survey identified 258 traditional medicine uses, spanning a total of 13 diseases categories and including 91 native and exotic plant species and one unidentified sample plant type. Gastrointestinal disorders (55% were most frequently treated with medicinal plants, followed by afflictions of the musculoskeletal system (25% and dermatological disorders (24%. Hospital information indicates that the most common diseases are acute respiratory infections (47% and acute diarrheal diseases (37%. The herbal remedies were mostly used in the form of teas and decoctions. The informants used mainly native plant species, although exotic species has been introduced to the pharmacopoeia. Conclusions The treatment of gastrointestinal disorders is the primary objective of the medical ethnobotany of the inhabitants of Huacareta, while respiratory system diseases are mostly treated in the hospital. Looking at the data from the Hospital records we can infer that gastrointestinal disorders are among the most common diseases in the study area.

    2014-01-01

    Introducción: Las malformaciones del tubo neural (MTN) representan la segunda causa más frecuente de anomalías congénitas, luego de las cardiopatías. En este grupo se destaca el mielomeningocele (MMC) por su mayor incidencia, y por ser la más incapacitante y la más compleja entre todas las demás malformaciones del sistema nervioso c`entral (SNC). En Bolivia, como en muchos países de Sudamérica, los bajos niveles socio-culturales y la debilidad en el sistema sanitario, hacen que su incidencia y su morbilidad, sean mayores que en las naciones más desarrolladas. Material y Métodos: Se realizó un estudio retrospectivo y descriptivo de 70 casos de MMC, atendidos por un equipo multidisciplinario en el Hospital Universitario Japonés (HUJ) de Santa Cruz de la Sierra, entre 2008-2011. De ellos, 60 fueron intervenidos quirúrgicamente. Resultados: Se realizaron controles prenatales sólo en 27 mujeres (38.6%), diagnosticándose una disrafia espinal en apenas dos casos (7.4%). La edad de ingreso del MMC en su mayoría fue después de las 24 horas (65.6%), predominando su localización en la región lumbosacra (64.3%). De ellos, 67.2% eran abiertos, presentando un 32.9% un daño neurológico motor parcial mientras que 47.1% tenían paraplejia por debajo de la lesión. De los 70 casos, tres (4.3%) no fueron intervenidos, por presentar defectos congénitos severos o estado general grave. Las principales complicaciones posoperatorias inmediatas fueron: dehiscencia de sutura y/o infección de la herida (16.6%), fístula de líquido cefalorraquídeo (LCR) (10%) e infección del SNC (11.7%). La mortalidad general y postoperatoria fue de 7.1% y 3.3%, respectivamente. Al mes de vida presentaban hidrocefalia un 80% de los pacientes operados, colocándose una derivación ventriculoperitoneal (DVP) de presión media. De 9 pacientes que tuvieron un acompanamiento de dos o más años, seis presentaron una médula anclada, que fueron intervenidas quirúrgicamente. Conclusi

To estimate the volume of breast milk consumed by Bolivian children under 36 months of age, and the monetary value of replacing that volume of breast milk with commercial substitutes. Methods. The analysis took into account the distribution of the infant population by age groups, the prevalence of breast-feeding practices (exclusive or partial in every age group, the average volume of breast milk consumed by the infants of a given age group, and the cost of breast milk production and replacement. Results. Bolivian infants annually consume more than 161 million liters of breast milk, which represents an average volume of 573 mL/day per infant under 1 year of age. The monetary value of breast milk consumed by the Bolivian infants amounts to US$ 274 million annually. The average cost of replacing breast milk with commercial substitutes for an infant adequately breast-fed for the first year of life would be US$ 407. Discussion. For the formulation and consolidation of policies and programs to protect, promote, and support breast-feeding to become a reality, it is necessary that the political leaders of Bolivia be aware of the enormous monetary value of breast milk.

  2. Bolivia's gas heads for Brazil as Argentina waits - and watches

    1998-01-01

    The first 1,800 km stretch of a 3,400 km natural gas pipeline from Bolivia to Brazil will start operating in December. First planned 50 years ago, the pipeline has long been expected to result in an immediate surge of gas use in Brazil. However, impending deep recession in Brazil makes this prospect less likely despite the power shortages which indicate the need for considerable gas imports. Initially, most Bolivian gas will flow through Brazil to Argentina. But gas production is expanding rapidly in Argentina and the supply contract with Bolivia ends in 1999. Plans are well advanced to build two gas lines into the south of the Brazil from Argentina. Ultimately, it is anticipated that Argentina, which has abundant reserves and a virtually saturated domestic market, will become the principal source of natural gas for Brazil. (UK)

    2015-02-24

    This study presents monthly and annual climate maps for relevant hydroclimatic variables in Bolivia. We used the most complete network of precipitation and temperature stations available in Bolivia, which passed a careful quality control and temporal homogenization procedure. Monthly average maps at the spatial resolution of 1 km were modeled by means of a regression-based approach using topographic and geographic variables as predictors. The monthly average maximum and minimum temperatures, precipitation and potential exoatmospheric solar radiation under clear sky conditions are used to estimate the monthly average atmospheric evaporative demand by means of the Hargreaves model. Finally, the average water balance is estimated on a monthly and annual scale for each 1 km cell by means of the difference between precipitation and atmospheric evaporative demand. The digital layers used to create the maps are available in the digital repository of the Spanish National Research Council.

    Full Text Available Since early in 2006, the republic of Bolivia has been ruled by the first indigenous president in that country’s history: the Aymara Evo Morales, union leader and first name in the ballot of the so-called “Movement for Socialism” (MAS. His political rise, electoral victory and government program have drawn considerable attention from international mass media and been the subject of valuable political and sociological analyses. From the perspective of comparative anthropology, the process can be understood as an instance, in the Andean cultural context, of what Anthony Wallace called a “revitalization movement,” triggered by the convergence, at a juncture of crisis begun in 1997, of a number of historical conditions of variable duration in Bolivia as a national project.

    Desde comienzos de 2006, la república de Bolivia cuenta con el primer presidente indígena de su historia: el aymara Evo Morales, dirigente sindical y cabeza de lista del llamado “Movimiento al Socialismo” (MAS. Su ascensión política, victoria electoral y programa de gobierno han llamado mucho la atención de los medios informativos internacionales y han sido objeto de valiosos análisis políticos y sociológicos. Desde la perspectiva de una antropología comparada, el proceso se ajusta bien, en el contexto cultural andino, a lo que Anthony Wallace llamara un “movimiento de revitalización”, desencadenado por la convergencia, en un periodo de crisis iniciado en 1997, de varias condiciones estructurales de duración histórica variable en Bolivia como proyecto nacional.

    The pathogenic fungus Batrachochytrium dendrobatidis (Bd) has been associated with amphibian declines worldwide but has not been well-studied among Critically Endangered amphibian species in Bolivia. We sampled free-living marbled water frogs Telmatobius marmoratus (Anura: Leptodactylidae) from Isla del Sol, Bolivia, for Bd using skin swabs and quantitative polymerase chain reactions. We detected Bd on 44% of T. marmoratus sampled. This is the first record of Bd in amphibians from waters associated with Lake Titicaca, Bolivia. These results further confirm the presence of Bd in Bolivia and substantiate the potential threat of this pathogen to the Critically Endangered, sympatric Titicaca water frog T. culeus and other Andean amphibians.

  14. The debate on family planning and reproductive rights in Bolivia.

    Science.gov (United States)

    De La Fuente, M

    1991-01-01

    Using Bolivia as the example, the author critiques international organization and health professional emphasis upon providing family planning services as inadequate to meet the needs and interests of poor women. The feminist and women's movements should be expected to fight to regain the right of self-determination, and to demand integral health care for women. Contraception will constitute but a component of this holistic approach. Poverty, natalism, development, and population policies are all interrelated issues in Bolivia as the country proceeds through a period of democratization. Where total fertility averages 5 children/women as it does in Bolivia, women should certainly have the right to choose contraception in the control of fertility. Simple provision of such services and supplies will not, however, suffice to solve more deeply rooted social and economic problems faced by those women. The author further fears that some parts of the feminist movement have forgotten that population and related policies developed and imposed by other cultures have little interest in respecting the self-determination of women as individuals. Support for these policies by movement members only reinforces and helps to reproduce existing conditions of poverty and unequal rights.

    Knowledge of the therapeutic efficacy of chloroquine for Plasmodium vivax infections improves the capacity for surveillance of anti-malarial drug resistance. The therapeutic efficacy of chloroquine as treatment was evaluated for uncomplicated Plasmodium vivax malaria in Bolivia. An in vivo efficacy study of chloroquine was undertaken in three regions of Bolivia--Riberalta, Guayaramerín and Yacuiba. Two hundred and twenty-three patients (84, 80, and 59 in the three regions, respectively) aged over 5 years old were administered with chloroquine (25 mg/kg/three days) and followed for 28 days. Blood levels of chloroquine and desethylchloroquine were measured on day 2 and on the day of reappearance of parasitemia. The cumulative incidence of treatment failure was calculated using the Kaplan and Meier survival analysis. The mean parasitemias (asexual) on day 0 were 6,147 parasites/μl of blood in the Riberalta population, 4,251 in Guayaramerín and 5,214 in Yacuiba. The average blood concentrations of chloroquine-desethylchloroquine during day 2 were 783, 817, and 815 ng/ml, respectively. No treatment failures were observed in Yacuiba, whereas in Riberalta and Guayaramerín, the frequencies of treatment failures were 6.2% and 10%. Blood levels of chloroquine and desethylchloroquine in patients with treatment failure showed values below 70 ng/ml on the day of reappearance of parasitemia. Resistance of Plasmodium vivax to chloroquine was not demonstrated in three regions of Bolivia.

    No information has been yet published on snakebite in Bolivia. The country includes very different ecological situations leading to various epidemiological risks. A study has been carried out to evaluate the incidence and location of snakebite, particularly in relation with altitude, in order to improve management. Investigations on snakebite epidemiology were based on a) cases treated in health facilities as reported by health authorities and b) household surveys carried out in areas with high variations of altitude, in various regions of Bolivia. An average of 700 bites was treated each year in Bolivia (national annual incidence = 8 bites per 100,000 people) with a great disparity between districts. Household surveys showed annual incidences ranged from 30 to 110 bites per 100,000 inhabitants depending on location. Annual mortality ranged 0.1-3.9 per 100,000 people. A significant and constant inverse correlation was shown between snakebite incidence and altitude, which may be explained by both snake and human distributions and activities. Notification of snakebite is useful for improving patient management and informing antivenom distribution. It should also involve the report of deaths and clinical details of envenomation.

    Full Text Available El Gobierno de Bolivia ha tenido desde 1983 un programa nacional para combatir los trastornos por deficiencia de yodo (TDY, que a principios de la década de 1980 afectaban a más de la mitad de la población del país. La principal estrategia empleada de forma sostenida en la lucha contra los TDY es la yodación de toda la sal destinada para consumo humano. En 1996, el Gobierno de Bolivia invitó a un grupo de expertos a revisar, en colaboración con los integrantes del programa dentro del país, cuánto se había avanzado hacia la eliminación de los TDY de todo el territorio nacional. El equipo revisor examinó los datos recolectados mediante las encuestas más recientes sobre la disponibilidad y el uso de la sal yodada y las concentraciones de yodo excretadas por la orina. Sobre la base de criterios internacionales establecidos para estos indicadores, el equipo llegó a la conclusión de que Bolivia había eliminado los TDY como problema de salud pública de alcance nacional, pese a pruebas de que algunas comunidades aisladas de los Andes todavía carecían de una ingesta adecuada de yodo. El equipo hizo recomendaciones para mejorar el programa y garantizar su sostenibilidad. Asimismo, examinó los métodos de producción y el control de la calidad del proceso de yodación y recomendó medidas para reducir la variabilidad del contenido de yodo en la sal.

The aim of this study was to evaluate the therapeutic efficacy of CQ in this setting. Patients in the Amazon region of northern Bolivia, were included in the study from May to November 2011 and the therapeutic efficacy of CQ was evaluated over a 28-day follow-up period. Patients with P. vivax mono-infection received 25 mg/Kg body weight of CQ over three days. The concentrations of CQ + desethylchloroquine (DCQ) in blood were determined at days 7 and 28 of follow up; at follow-up and on the day of treatment failure was administered PQ. One hundred patients fulfilled the inclusion criteria, two were lost to follow up and another two were later excluded for protocol violation. Of the 96 patients who completed the follow up 10 showed TF; one presented continued parasitaemia until day 7 of follow up, three on day 21 and six on day 28 of follow up. The geometric mean of CQ + DCQ on day 7 was 321.7 ng/ml (range 197-535 ng/ml). In six patients with TF the CQ + DCQ concentrations in blood on the day of TF were >100 ng/ml. The rate of resistance was 6.5%. The present study demonstrates the presence of resistance to CQ in the treatment of malaria by P. vivax in the Amazon region of Bolivia. New clinical trials are needed to establish alternative treatments against these parasites in this region of South America.

    Bolivia is currently undergoing a series of healthcare reforms centred around the Unified Family, Community and Intercultural Health System (SAFCI), established in 2008 and Law 475 for Provision of Comprehensive Health Services enacted in 2014 as a first step towards universal health coverage. The SAFCI model aims to establish an intercultural, intersectoral and integrated primary health care (PHC) system, but there has not been a comprehensive analysis of effective strategies towards such an end. In this systematic review, we analyse research into developing PHC in Bolivia utilizing MEDLINE, the Virtual Health Library and grey literature from Pan American Health Organization/World Health Organization's internal database. We find that although progress has been made towards implementation of a healthcare system incorporating principles of PHC, further refining the system and targeting improvements effectively will require increased research and evaluation. Particularly in the 7 years since establishment of SAFCI, there has been a dearth of PHC research that makes evaluation of such key national policies impossible. The quantity and quality of PHC research must be improved, especially quasi-experimental studies with adequate control groups. The infrastructure for such studies must be strengthened through improved financing mechanisms, expanded institutional capacity and setting national research priorities. Important for future progress are improved tracking of health indicators, which in Bolivia are often out-of-date or incomplete, and prioritization of focused national research priorities on relevant policy issues. This study aims to serve as an aid towards PHC development efforts at the national level, as well as provide lessons for countries globally attempting to build effective health systems accommodating of a multi-national population in the midst of development. © The Author 2015.

    Full Text Available Chagas disease is a major public health problem in Bolivia. In the city of Cochabamba, 58% of the population lives in peripheral urban districts ("popular zones" where the infection prevalence is extremely high. From 1995 to 1999, we studied the demographics of Chagas infections in children from five to 13 years old (n = 2218 from the South zone (SZ and North zone (NZ districts, which differ in social, environmental, and agricultural conditions. Information gathered from these districts demonstrates qualitative and quantitative evidence for the active transmission of Trypanosoma cruzi in urban Cochabamba. Seropositivity was high in both zones (25% in SZ and 19% in NZ. We observed a high risk of infection in children from five to nine years old in SZ, but in NZ, a higher risk occurred in children aged 10-13, with odds ratio for infection three times higher in NZ than in SZ. This difference was not due to triatomine density, since more than 1,000 Triatoma infestans were captured in both zones, but was possibly secondary to the vector infection rate (79% in SZ and 37% in NZ. Electrocardiogram abnormalities were found to be prevalent in children and pre-adolescents (SZ = 40%, NZ = 17%, indicating that under continuous exposure to infection and re-infection, a severe form of the disease may develop early in life. This work demonstrates that T. cruzi infection should also be considered an urban health problem and is not restricted to the rural areas and small villages of Bolivia.

In this case 121 records of specimens of the 11 species of the genus Attalea of Bolivia and their relationship with 30 ecological systems that approximate their scope of distribution at regional level are released. To this end, the geographical coordinates were systematized, verified and corrected. Localities of all the specimens collected from the genus Attalea in order to compare them with ecological systems, using the ArgGis tools. We then elaborate a dendrogram (species vs. ecological systems using the minimum distance method in the R program. The analysis of the relation of the species with the ecological systems highlights a species that does not compose to the southwest amazon: A. eichleri and that is native to ecological systems of the Cerrado. Among the SW Amazonian Attalea species, A. blepharopus (endemic to Bolivia is isolated from the others and the rest subgroup species according to their presence in forests and savannas, in addition to the subandean and alluvial, as it is for A. princeps, which is found in 17 systems (57%. Eight species of Attalea are common with Peru and 10 with Brazil. It is important to relate the hierarchical grouping of the Attalea species with ecological systems in function of landscape dynamics to document their space patterns and also for their conservation.

This study of these fungi in lowland Bolivian Amazon forests of Pando Department revealed the presence of 180 species, 101 of which are reported as new for Bolivia. The following 15 species are mentioned for the first time from South America: Anisomeridium guttuliferum Lücking, Byssolecania pluriseptata Breuss, Caprettia confusa Lücking & Sipman, Chroodiscus submuralis Lücking, Coenogonium barbatum Lücking, Aptroot & L.

The up-to-date list of foliicolous lichens of Bolivia now numbers 218 species, 52% more than known previously. The foliicolous lichen biota of Pando, a substantial part of the Bolivian Amazon, has clear affinities to neighboring countries due to the significant proportion of species typical for lowland and submontane humid forests in the Neotropics. Analyses of the lichen diversity in the area suggest that its species composition is positively correlated with the presence of specific forest types.

    The knowledge of the gallstones chemical composition is very important from view point of lithogenesis and possible medical therapy of dissolution. The composition (chemical) of gallstones in 30 consecutive cholecystectomized patients were studied in the 2nd. Department of Surgery of Hospital San Juan de Dios, Santa Cruz, Bolivia (altitude 1900 m). All gallbladder stones were washed, counted, measured and dried before sending them to Japan to be processed. The composition of gallstones was analyzed by infrared absorption spectroscopy. Cholesterolemia, age, sex and number of stones were analyzed in cases of pure cholesterol stones. The incidence of pure cholesterol stones was 56.6%, statistically similar to be reported by other authors, but very low if compared with the valley area of Bolivia (Cochabamba altitude 2300 m) where hypothyroidism is frequent. Hypercholesterolemia had little relation with the pure cholesterol gallstones. There was no difference in the chemical composition and the size of the stones, but while their number was small, cholesterol stones were more frequent. The low incidence of pure cholesterol stones may show a bad nutritional condition of our population (poor fat and protein content) and this result is important in order in using the new advance: lithodissolvent drugs.

    To determine the birth prevalence of cleft lip and palate (CL +/- P) in the municipality of Sucre, Bolivia. To ascertain whether the birth prevalence in this region differs significantly from birth prevalence reported in similar populations and other racial groups. Twenty-eight clefts were identified among 22,746 live births between the years 1995 and 2001 in three maternity hospitals in the city. The total birth prevalence of CL +/- P was 1.23/1000 live births per year. There were 12 clefts of the lip alone (birth prevalence 0.53/1000 per year), 15 cleft lip and palate (0.66/1000 per year), and one cleft palate only (0.04/1000 per year). The birth prevalence was not significantly different from birth prevalence published previously in South American populations, although it is lower than previously published data from Bolivia. The birth prevalence of CL +/- P in this South American population was similar to published data in white subjects and between those found in black and oriental groups. The sex ratio and birth prevalence of simultaneous congenital malformations also did not differ from previously published figures.

    Full Text Available Although bigleaf mahogany [Swietenia macrophylla King (Meliaceae] is the premier timber species of Latin America, its exploitation is unsustainable because of a pattern of local depletion and shifting supply. We surveyed experts on the status of mahogany in Bolivia and Peru, the world's past and present largest exporters. Bolivia no longer has commercially viable mahogany (trees > 60 cm diameter at breast height across 79% of its range. In Peru, mahogany's range has shrunk by 50%, and, within a decade, a further 28% will be logged out. Approximately 15% of the mahogany range in these two countries is protected, but low densities and illegal logging mean that this overestimates the extent of mahogany under protection. The international community can support mahogany conservation by funding park management and by encouraging independent verification of the legality of mahogany in trade. Our findings demonstrate that a systematic expert survey can generate reliable and cost-effective information on the status of widespread species of concern and help to inform appropriate management policy.

    This investigation aimed to document surgical capacity at public medical centers in a middle-income Latin American country using the Surgeons OverSeas (SOS) Personnel, Infrastructure, Procedures, Equipment, and Supplies (PIPES) survey tool. We applied the PIPES tool at six urban and 25 rural facilities in Santa Cruz, Bolivia. Outcome measures included the availability of items in five domains (Personnel, Infrastructure, Procedures, Equipment, and Supplies) and the PIPES index. PIPES indices were calculated by summing scores from each domain, dividing by the total number of survey items, and multiplying by 10. Thirty-one of the 32 public facilities that provide surgical care in Santa Cruz were assessed. Santa Cruz had at least 7.8 surgeons and 2.8 anesthesiologists per 100,000 population. However, these providers were unequally distributed, such that nine rural sites had no anesthesiologist. Few rural facilities had blood banking (4/25), anesthesia machines (11/25), postoperative care (11/25), or intensive care units (1/25). PIPES indices ranged from 5.7-13.2, and were significantly higher in urban (median 12.6) than rural (median 7.8) areas (P Bolivia's development status. Unfortunately, surgeons are limited in rural areas by deficits in anesthesia and perioperative services. These results are currently being used to target local quality improvement initiatives.

  4. Bolivia: New Presidential Electoral System and Political Parties Coordination

    Directory of Open Access Journals (Sweden)

    Mario Torrico

    2015-01-01

    Full Text Available This article analyzes the incentives generated by presidential electoral systems in Bolivia. The system that was in place until 2005 led to the formation of coalition governments that aimed at giving the Executive the majority in Congress. However, these coalitions gradually lost the electorate confidence, and citizens sought alternative political options to major parties from the early nineties on, giving rise to a social dissatisfaction with democracy. This, in turn, led to the resignation of Sánchez de Lozada and, later, to the triumph of Evo Morales. The new electoral system for electing the president, included in the 2009 Constitution, increases the likelihood that the elected government does not have a majority in Congress. Similar situations in the past led to political crisis and anticipation of elections. In a more favorable context characterized by greater satisfaction with democracy and their parties, the challenge is to take decisions inclusively, something unprecedented in Bolivian politics.

Showing data that reveal that the bolivian economic performance in the neoliberal period was better compared to the performance of Argentina, Brazil and Mexico, this article offers an alternative explanation, which not denying the poverty of the bolivian majorities, asserts that the breakdown of the political system and the parties that alternated in power for twenty years is the main factor explaining the rise of the first indigenous president.

    The neurosurgical boot camp has been fully incorporated into U.S. postgraduate education. This is the first implementation of the neurosurgical boot in a developing country. To advance neurosurgical education, we developed a similar boot camp program, in collaboration with Bolivian neurosurgeons, to determine its feasibility and effectiveness in an international setting. In a collective effort, the Bolivian Society for Neurosurgery, Foundation for International Education in Neurological Surgery, Solidarity Bridge, and University of Massachusetts organized and executed the first South American neurosurgical boot camp in Bolivia in 2015. Both U.S. and Bolivian faculty led didactic lectures followed by a practicum day using mannequins and simulators. South American residents and faculty were surveyed after the course to determine levels of enthusiasm and their perceived improvement in fund of knowledge and course effectiveness. Twenty-four neurosurgery residents from 5 South American countries participated. Average survey scores ranged between 4.2 and 4.9 out of 5. Five Bolivian neurosurgeons completed the survey with average scores of 4.5-5. This event allowed for Bolivian leaders in the field to unify around education, resulting in the formation of an institute to continue similar initiatives. Total cost was estimated at $40 000 USD; however, significant faculty, industry, and donor support helped offset this amount. The first South American neurosurgical boot camp had significant value and was well received in Bolivia. This humanitarian model provides a sustainable solution to education needs and should be expanded to other regions as a means for standardizing the core competencies in neurosurgery.

    In order to establish a chronology of two nearby ice cores from a glacier at Illimani (6438 m), Bolivia, a broad dating approach is presented here, which in particular makes use of the fast, simple, and nearly nondestructive electrical conductivity method (ECM) that provides a highly resolved record. Thus, ECM is suited for counting annual layers in the ice, especially for ice cores extracted from high-mountain glaciers with a fast layer thinning. Furthermore, ECM can be used for detecting volcanic signals. Annual signals in the ECM record of the Illimani ice core were identified using the 1964 A.D. tritium reference horizon and were counted along 125 m or 90% of the core, representing the time period from 1200 ± 240 A.D. (estimated accumulated error) to 1999 A.D. The resulting age-depth relationship was supported by counting annual peaks in the microparticle record as well as by nuclear dating using the decay of 210Pb. The identification of volcanic signals originating from eruptions such as Pinatubo (1991 A.D.), El Chichón (1982 A.D.), Agung (1963 A.D.), Krakatoa (1883 A.D.), Tambora (1815 A.D.), and the Unknown 1258 A.D. significantly reduced the uncertainty of annual layer counting (ALC) to ±2 years in the vicinity of these events.

    Full Text Available Heavy domestic and peridomestic infestations of Triatoma infestans were controlled in two villages in southern Bolivia by the application of deltamethrin SC25 (2.5% suspension concentrate at a target dose of 25 mg a.i./m². Actual applied dose was monitored by HPLC analysis of filter papers placed at various heights on the house walls, and was shown to range from 0 to 59.6 about a mean of 28.5 mg a.i./m². Wall bioassays showed high mortality of T. infestans during the first month after the application of deltamethrin. Mortality declined to zero as summer temperatures increased, but reappeared with the onset of the following winter. In contrast, knockdown was apparent throughout the trial, showing no discernible temperature dependence. House infestation rates, measured by manual sampling and use of paper sheets to collect bug faeces, declined from 79% at the beginning of the trial to zero at the 6 month evaluation. All but one of the houses were still free of T. infestans at the final evaluation 12 months after spraying, although a small number of bugs were found at this time in 5 of 355 peridomestic dependencies. Comparative cost studies endorse the recommendation of large-scale application of deltamethrin, or pyrethroid of similar cost-effectiveness, as a means to eliminate domestic T. infestans populations in order to interrupt transmission of Chagas disease

    Seismic, stratigraphic, structural, and geochemical data from the Altiplano, northern Subandean, and northern plains of Bolivia were interpreted in order to evaluate the exploration potential of each province. Identification of three possible source rock intervals, primarily the Devonian and secondarily the Permian and Cretaceous, was used as the basis for recognizing active hydrocarbon systems. For those areas containing source intervals, their analysis revealed that possible reservoir and seal units range in age from Paleozoic to Tertiary; the majority of structures, however, are Eocene or younger. With these general concepts in mind, traps were identified in all three sedimentary provinces. In the northern Altiplano, the most prospective area is along the eastern margin near a southwest and west-vergent thrust belt where hanging-wall anticlines and a warped Eocene-Oligocene(.) unconformity surface form the most likely potential traps. In the central and southern Altiplano, both thrust-related and wrench-related structures present possible exploration targets. In the northern Subandean and Beni plains north of the Isiboro-Chapare area, traps can be classified into two broad groups. First, there are a wide variety of structural traps within the northern Subandean thrust belt, the most attractive of which are footwall structures that have been shielded from surface flushing by hanging-wall strata. Second, in the plains just northeast of the thrust belt, hydrocarbons sourced from the remnant Paleozoic basin may have migrated onto the Isarsama and Madidi highs.

  6. Marital Dissolution and Child Educational Outcomes in San Borja, Bolivia.

    2016-12-01

    Serial monogamy is likely an adaptive mating strategy for women when the expected future fitness gains with a different partner are greater than expected future fitness with one's current partner. Using interview data from more than 400 women in San Borja, Bolivia, discrete-time event history analyses and random effects regression analyses were conducted to examine predictors of marital dissolution, separated by remarriage status, and child educational outcomes. Male income was found to be inversely associated with women's risk of "divorce and remarriage," whereas female income is positively associated with women's risk of "divorce, but not remarriage." Children of women who divorce and remarry tend to have significantly lower educational outcomes than children of married parents, but women with higher incomes are able to buffer their children from the negative educational outcomes of divorce and remarriage. Counter to predictions, there is no evidence that women with kin in the community have a significant difference in likelihood of divorce or a buffering effect of child outcomes. In conclusion, predictors of divorce differ depending on whether the woman goes on to remarry, suggesting that male income may be a better predictor of a serial monogamy strategy whereas female income predicts marital dissolution only. Thus, women who are relatively autonomous because of greater income may not benefit from remarriage.

    2014-03-01

    Uturuncu is a dormant volcano in the Altiplano of SW Bolivia. A present day ~70 km diameter interferometric synthetic aperture radar (InSAR) anomaly roughly centred on Uturuncu's edifice is believed to be a result of magma intrusion into an active crustal pluton. Past activity at the volcano, spanning 0.89 to 0.27 Ma, is exclusively effusive and almost all lavas and domes are dacitic with phenocrysts of plagioclase, orthopyroxene, biotite, ilmenite and Ti-magnetite plus or minus quartz, and microlites of plagioclase and orthopyroxene set in rhyolitic groundmass glass. Plagioclase-hosted melt inclusions (MI) are rhyolitic with major element compositions that are similar to groundmass glasses. H2O concentrations plotted versus incompatible elements for individual samples describe a trend typical of near-isobaric, volatile-saturated crystallisation. At 870 °C, the average magma temperature calculated from Fe-Ti oxides, the average H2O of 3.2 ± 0.7 wt% and CO2 typically 0.5 Ma compared to those intrusion of more mafic magmas into the evolving, shallow plutonic mush also occurred further amplifying local temperature fluctuations. Crystallisation and resorption of accessory phases, particularly ilmenite and apatite, can be detected in MI and groundmass glass trace element covariation trends, which are oblique to WRs. Marked variability of Ba, Sr and La in MI can be attributed to temperature-controlled, localised crystallisation of plagioclase, orthopyroxene and biotite within the evolving mush.

  14. International Uranium Resources Evaluation Project (IUREP) orientation phase mission summary report: Bolivia

    International Nuclear Information System (INIS)

    1985-01-01

    A report has recently been published which describes the findings of the International Uranium Resources Evaluation Project (IUREP) mission to Bolivia. The IUREP Orientation Phase mission to Bolivia estimates that the Speculative Uranium Resources of that country fall within the range of 100 to 107 500 tonnes uranium. The majority of this potential is expected to be located in the Precambrian crystalline and sedimentary rocks of the southwestern part of the Central Brazilian Shield. Other potentially favourable geologic environments include Palaeozoic two mica granites and their metasedimentary hosts, Mesozoic granites and granodiorites as well as the intruded formations and finally Tertiary acid to intermediate volcanics. The mission recommends that approximately US$ 13 million be spent on exploration in Bolivia over a five-year period. The majority of this expenditure would be for airborne and surface exploration utilising geologic, magnetometric, radiometric, and geochemical methods and some pitting, trenching, tunneling and drilling to further evaluate the discovered occurrences.

    Full Text Available The second-hand clothing trade started widely in Bolivia in 1994. This kind of trade usually involves popular globalization activities, whose practices are often identified by State agencies as illegal, although with natural popular acceptance. It is established within a complex system of networks, and takes advantage of distribution (stock and transfer meshes and knots, with the consequent conformation of connected territorial circuits. This paper aims at analyzing the second-hand clothing trade in three locations: Santa Cruz de la Sierra and Puerto Quijarro (Bolivia, and Corumbá (Brazil. The purpose is to identify the route and the nuances regarding the second-hand clothing distribution network from Santa Cruz de la Sierra to Corumbá, on the Bolivia-Brazil border.

    Full Text Available Sajama National Park, the first protected area in Bolivia, includes five indigenous communities with a primary production base of pastoralism. The semi-arid region of the Central Andes is one of the most extreme areas of human occupation at 4200 meters altitude and affected by high climatic variability. This paper studies the relations between climate variability, resilience, biodiversity of pastures and pastoral production in Sajama National Park. We present a botanical study of palatable pasture herbs between two years, one humid (2006 and the other dry (2007. Thirty vascular plants were recorded. The number of species and the cover of iro (Festuca ortophylla peak in areas of intermediate disturbance; areas that are at a medium distance from camelid corrals. On the other hand, the cover of ephemeral plants between tussocks increases in high disturbance areas. This is interpreted as a result of the tradeoff between the damage of grazing and the benefit of the fertilization produced by the herding animals. The local people clearly perceive strong impacts of climate change, combined with changes in management and human pressures. The social dynamics and production management, combined with climate warming, water reduction, and the increasing variability of surface water regimes create potential risks for the local sustainability of pastoralism.

    2015-01-01

    Uruguay and Bolivia are two countries that show heterogenicity of the Latin American region, including the national income, the expenditure on health and the services for renal care. In Bolivia, there is manpower shortage for renal care with only 5 nephrologists per million people (pmp) and the prevalence of patients on dialysis is only 200 pmp. This is much lower than the mean prevalence rate of renal replacement therapy for Latin America as a whole. Uruguay on the other hand has more dedicated renal resources with 50 nephrologists pmp, and renal replacement therapy is provided to ~ 1,000 dialysis patients pmp. In November 2012, a collaborative project financed by the Uruguayan International Cooperation Agency was signed by both the Uruguay and Bolivia Ministries of Health, and the goal was to develop a comprehensive program for the prevention and management of all stages of chronic kidney disease (CKD) in Bolivia. The specific objectives were to: a) promote renal healthcare in the primary healthcare setting, b) identify kidney disease in populations at risk, and c) optimize patient care at all stages of CKD, including dialysis and transplantation supported with a national ESRD registry in Bolivia. As a first step, delegates from the Bolivian Health Ministry, visited Uruguay in April 2014, primarily to strengthen the development of tools required for developing and maintaining a national registry. In addition, during this visit, a meeting with the president of the Latin American Society of Nephrology and Hypertension (SLANH) culminated in designing a training program for peritoneal dialysis. This highly cooperative relationship is advancing the prevention and care of CKD in Bolivia and may serve as a model for international approaches to advance system level CKD care in countries with limited healthcare resources.

    Background We conducted a study of congenital Trypanosoma cruzi infection in Santa Cruz, Bolivia. Our objective was to apply new tools to identify weak points in current screening algorithms, and find ways to improve them. Methods Women presenting for delivery were screened by rapid and conventional serological tests. For infants of infected mothers, blood specimens obtained on days 0, 7, 21, 30, 90, 180, and 270 were concentrated and examined microscopically; serological tests were performed for the day 90, 180, and 270 specimens. Maternal and infant specimens, including umbilical tissue, were tested by polymerase chain reaction (PCR) targeting the kinetoplast minicircle and by quantitative PCR. Results Of 530 women, 154 (29%) were seropositive. Ten infants had congenital T. cruzi infection. Only 4 infants had positive results of microscopy evaluation in the first month, and none had positive cord blood microscopy results. PCR results were positive for 6 (67%) of 9 cord blood and 7 (87.5%) of 8 umbilical tissue specimens. PCR-positive women were more likely to transmit T. cruzi than were seropositive women with negative PCR results (P < .05). Parasite loads determined by quantitative PCR were higher for mothers of infected infants than for seropositive mothers of uninfected infants (P < .01). Despite intensive efforts, only 58% of at-risk infants had a month 9 specimen collected. Conclusions On the basis of the low sensitivity of microscopy in cord blood and high rate of loss to follow-up, we estimate that current screening programs miss one-half of all infected infants. Molecular techniques may improve early detection. PMID:19877966

    This study compares gender differences regarding knowledge, practice, and symptoms of intoxication when handling pesticides in farming. Data were gathered in La Paz County, Bolivia, in 2008 and 2009. Poor knowledge on safe handling, hazardous working practices, and use of very toxic pesticides were...... seen. Being a female and having a low educational level were risk factors for "poor knowledge on pesticides" and a "risky behavior when handling pesticides." Females reported more symptoms of intoxication. The gender differences on knowledge and handling practices might explain why females report more...... symptoms. To minimize this gap, education and agricultural services should be made more accessible to female farmers in Bolivia....

    BACKGROUND: Pesticide use and its consequences are of concern in Bolivia due to an intensive and increasing use. METHODS: To assess the magnitude and reasons for occupational pesticide intoxication, a cross-sectional study with interviews and blood-tests was performed among 201 volunteer farmers...... spraying operations while this had no influence on the serum cholinesterase level. CONCLUSION: The study showed that occupational pesticide intoxications were common among farmers and did depend on multiple factors. Pesticide use is probably one of the largest toxicological problems in Bolivia......, and a coordinated action by authorities, society and international bodies is needed to limit the number of intoxications and the environmental pollution....

  3. International Uranium Resources Evaluation Project (IUREP) orientation phase mission report: Bolivia. Draft

    1982-08-01

    The uranium exploration done so far in Bolivia has been carried out by COBOEN, partly with IAEA support, and AGIP S.p.A. of Italy, which between 1974 and 1978 explored four areas in various parts of Bolivia under a production sharing contract with COBOEN. The basic objective of the International Uranium Resources Evaluation Project (IUREP) is to 'review the present body of knowledge pertinent to the existence of uranium resources, to review and evaluate the potential for discovery of additional uranium resources, and to suggest new exploitation efforts which might be carried out in promising areas in collaboration with the country concerned'. Following the initial bibliographic study which formed Phase I of IUREP, it was envisaged that a further assessment in cooperation with, and within, the country concerned would provide a better delineation of areas of high potential and a more reliable estimate as to the degree of favourability for the discovery of additional uranium resources. It was planned that such work would be accomplished through field missions to the country concerned and that these field missions and the resulting report would be known as the Orientation Phase of IUREP. The purpose of the Orientation Phase mission to Bolivia was a) to develop a better understanding of the uranium potential of the country, b) to make an estimate of the Speculative Resources of the country, c) to delineate areas favourable for the discovery of these uranium resources, d) to make recommendations as appropriate on the best methods for evaluating the favourable areas, operating procedures and estimated possible costs, e) to develop the logistical data required to carry out any possible further work, and f) to compile a report which would be immediately available to the Bolivian authorities. The mission reports contains information about a general introduction, non-uranium exploration and mining in Bolivia, manpower in exploration, geological review of Bolivia, past uranium

    2014-05-01

    Santa Fe is a Sn-Zn-Pb-Ag ore deposit located in the Oruro district, Central Andean Tin Belt, Bolivia. Mineralization occurs in veins and disseminations. It is hosted in Silurian shales and greywackes. The sedimentary sequence is folded and unconformably covered by a volcanic complex of the Morococala Formation, mainly constituted by tuffs of Miocene age. A wide Nº40 shear zone and two systems of fracture are developed. A Nº40 fracture system, dipping 60ºW, which hosts Sn and Zn minerals, and other in the same direction but dipping 75ºE, which is related to Zn-Pb-Ag veins. The mineralization is associated to intrusive felsic magmatism. Although there are not intrusive rocks in Santa Fe, a dyke and the felsic San Pablo stock occur at a distance of about 10 km. In the present work we describe the geology and mineralogy of the Santa Fe deposit. X-ray diffraction, scanning electron microscopy and electron microprobe analyses were used to characterize the minerals. Veins are filled with quartz and an ore mineral assemblage of cassiterite, sulfides and sulfosalts. Cassiterite constitutes the earliest formed mineralization. Preliminar microprobe analyses indicate that it is nearly pure, with negligible contents in Nb and Ta. Rutile occurs as a late phase associated with a late generation of cassiterite. It forms thin neddle-like crystals. In addition, Sn is also present in sulfides as stannite, stannoidite and kësterite. Other sulfides are pyrrhotite, pyrite, arsenopyrite, galena, sphalerite, marchasite and argentite. Bismuthinite and berndite are found nin trace amounts. Sulfosalts include tetrahedrite, myarhyrite, boulangerite, jamesonite, franckeite, zinckenite, cilindrite and andorite. Associated with the mineralization, several phosphate minerals are found filling cavities and small fractures. The most abundant are monacite (Ce,La,Nd,Th)PO4 and plumbogummite (PbAl3(PO4)2(OH)5•(H2O)). Crandallite CaAl3(PO4)2(OH)5•(H2O) and vivianite (Fe3+(PO4)2•8(H2O)) also

    Directory of Open Access Journals (Sweden)

    Christopher Strunk

    2013-09-01

    Full Text Available Migrant remittances are increasingly seen as a potential form of development in the global South, but the impact of international migration on sending regions is far from straightforward. In this article, I analyze migrant communities of origin in rural Bolivia as dynamic places that are constantly reproduced through connections with other places. I document the movement of migrant practices between Washington D.C. and Cochabamba and the influence of monetary and non-monetary flows on Bolivian cultural practices, politics, and development. I demonstrate how hometown associations and returning migrants have transferred organizational practices and political ideas about development from the United States to rural Bolivia. In addition, I explore migration’s role in struggles over belonging in Cochabamba, focusing on the efforts by migrants in Washington D.C. to stake their claim through transnational houses and collective remittance projects and on recent internal migration from other regions in Bolivia. Finally, I assess the sustainability of migrant-led development in Cochabamba. Although collaboration with migrants can strengthen the local state by providing more resources, it conditions the type of development that can take place and has yet to provide adequate opportunities for returning migrants or young people in rural Bolivia.

    2012-01-01

    Acinetobacter baumannii is an emerging multidrug-resistant pathogen and very little information is available regarding its imipenem resistance in Latin American countries such as Bolivia. This study investigated the antimicrobial resistance profile of 46 clinical strains from different hospitals in Cochabamba, Bolivia, from March 2008 to July 2009, and the presence of carbapenemases as a mechanism of resistance to imipenem. Isolates were obtained from 46 patients (one isolate per patient; 30 males,16 females) with an age range of 1 day to 84 years, and were collected from different sample types, the majority from respiratory tract infections (17) and wounds (13). Resistance to imipenem was detected in 15 isolates collected from different hospitals of the city. These isolates grouped into the same genotype, named A, and were resistant to all antibiotics tested including imipenem, with susceptibility only to colistin. Experiments to detect carbapenemases revealed the presence of the OXA-58 carbapenemase. Further analysis revealed the location of the bla(OXA-58) gene on a 40 kb plasmid. To our knowledge, this is the first report of carbapenem resistance in A. baumannii isolates from Bolivia that is conferred by the OXA-58 carbapenemase. The presence of this gene in a multidrug-resistant clone and its location within a plasmid is of great concern with regard to the spread of carbapenem-resistant A. baumannii in the hospital environment in Bolivia.

  13. The emergence, growth and decline of political priority for newborn survival in Bolivia.

    Smith, Stephanie L

    2014-12-01

    Bolivia is expected to achieve United Nations Millennium Development Goal Four, reducing under-five child mortality by two-thirds between 2021 and 2025. However, progress on child mortality reduction masks a disproportionately slow decline in newborn deaths during the 2000s. Bolivia's neonatal mortality problem emerged on the policy agenda in the mid-1990s and grew through 2004 in relationship to political commitments to international development goals and the support of a strong policy network. Network status declined later in the decade. This study draws upon a framework for analysing determinants of political priority for global health initiatives to understand the trajectory of newborn survival policy in Bolivia from the early 1990s. A process-tracing case study methodology is used, informed by interviews with 26 individuals with close knowledge of newborn survival policy in the country and extensive document analysis. The case of newborn survival in Bolivia highlights the significance of political commitments to international development goals, health policy network characteristics (cohesion, composition, status and key actor support) and political transitions and instability in shaping agenda status, especially decline-an understudied phenomenon considering the transitory nature of policy priorities. The study suggests that the sustainability of issue attention therefore become a focal point for health policy networks and analyses.

  15. The effectiveness of market-based conservation in the tropics: forest certification in Ecuador and Bolivia.

    Science.gov (United States)

    Ebeling, Johannes; Yasué, Maï

    2009-02-01

    During the last decade, forest certification has gained momentum as a market-based conservation strategy in tropical forest countries. Certification has been promoted to enhance forest management in countries where governance capacities are insufficient to adequately manage natural resources and enforce pertinent regulations, given that certification relies largely on non-governmental organisations and private businesses. However, at present there are few tropical countries with large areas of certified forests. In this study, we conducted semi-structured stakeholder interviews in Ecuador and Bolivia to identify key framework conditions that influence the costs and benefits for companies to switch from conventional to certified forestry operations. Bolivia has a much greater relative area under certified forest management than Ecuador and also significantly more certified producers. The difference in the success of certification between both countries is particularly notable because Bolivia is a poorer country with more widespread corruption, and is landlocked with less access to export routes. Despite these factors, several characteristics of the Bolivian forest industry contribute to lower additional costs of certified forest management compared to Ecuador. Bolivia has stronger government enforcement of forestry regulations a fact that increases the cost of illegal logging, management units are larger, and vertical integration in the process chain from timber extraction to markets is higher. Moreover, forestry laws in Bolivia are highly compatible with certification requirements, and the government provides significant tax benefits to certified producers. Results from this study suggest that certification can be successful in countries where governments have limited governance capacity. However, the economic incentives for certification do not only arise from favourable market conditions. Certification is likely to be more successful where governments enforce

  16. Shaded Relief with Height as Color, Iturralde Structure, Bolivia

    2002-01-01

    An 8-kilometer (5-mile) wide crater of possible impact origin is shown in this view of an isolated part of the Bolivian Amazon from the Shuttle Radar Topography Mission. The circular feature at the center-left of the image, known as the Iturralde Structure, is possibly the Earth's most recent 'big' impact event recording collision with a meteor or comet that might have occurred between 11,000 and 30,000 years ago.Although the structure was identified on satellite photographs in the mid-1980s, its location is so remote that it has only been visited by scientific investigators twice, most recently by a team from NASA's Goddard Space Flight Center in September 2002. Lying in an area of very low relief, the landform is a quasi-circular closed depression only about 20 meters (66 feet) in depth, with sharply defined sub-angular 'rim' materials. It resembles a 'cookie cutter' in that its appearance 'cuts' the heavily vegetated soft-sediments and pampas of this part of Bolivia. The SRTM data have provided investigators with the first topographic map of the site and will allow studies of its three-dimensional structure crucial to determining whether it actually is of impact origin.Two visualization methods were combined to produce this image: shading and color coding of topographic height. The shade image was derived by computing topographic slope in the northwest-southeast direction. North-facing slopes appear bright and south-facing slopes appear dark. Color coding is directly related to topographic height, with brown and green at the lower elevations, rising through yellow and brown to white at the highest elevations.Elevation data used in this image was acquired by the Shuttle Radar Topography Mission aboard Space Shuttle Endeavour, launched on Feb. 11, 2000. The mission used the same radar instrument that comprised the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) that flew twice on Endeavour in 1994.

    2003-01-01

    Pando Province, Bolivia, and adjacent parts of Brazil and Peru are seen in this visualization of Shuttle Radar Topography Mission (SRTM) elevation data covering part of the Amazon Basin. Most of this region is covered by tropical rainforest and is still largely unaltered by development, though new roads are providing increased access to the area, leading to changes in the landscape. SRTM data provide the first detailed three-dimensional look at the landforms of this region, and the Amazon Basin in its entirety, and will be particularly helpful in understanding the hydrologic patterns as environmental management becomes increasingly important.River drainage across this area flows generally east-northeast away from the nearby Andes Mountains. The most prominent river channels seen here are the Purus River in the northwest (upper left) and the Madre de Dios River, which crosses the south central (lower central) part of this view. The Beni and Mamore Rivers combine with the Madre de Dios in the eastern (right central) area to form the Madeira River, which flows northeast to eventually meet the Amazon River near Manaus.The Trans-Amazon Highway crosses the northern half of the scene, and subtle evidence of rainforest clear cutting, facilitated by this easy access, is apparent just north of the scene center, even at the low resolution of this display (740 m or 2428 feet). As seen here, clear cutting patterns in the rainforest typically show a pattern of parallel lines. SRTM mapped the shape of the Earths solid surface (not exclusively the ground surface), which includes to some degree land covers such as forests. Thus, SRTM data are capable of revealing deforestation patterns.For a smaller, annotated version of this image, please select Figure 1, below: [figure removed for brevity, see original site] (image size: 184k JPEG)A combination of visualization methods was used to produce this image, based on shading and color coding.

    Full Text Available El Gobierno de Bolivia ha tenido desde 1983 un programa nacional para combatir los trastornos por deficiencia de yodo (TDY, que a principios de la década de 1980 afectaban a más de la mitad de la población del país. La principal estrategia empleada de forma sostenida en la lucha contra los TDY es la yodación de toda la sal destinada para consumo humano. En 1996, el Gobierno de Bolivia invitó a un grupo de expertos a revisar, en colaboración con los integrantes del programa dentro del país, cuánto se había avanzado hacia la eliminación de los TDY de todo el territorio nacional. El equipo revisor examinó los datos recolectados mediante las encuestas más recientes sobre la disponibilidad y el uso de la sal yodada y las concentraciones de yodo excretadas por la orina. Sobre la base de criterios internacionales establecidos para estos indicadores, el equipo llegó a la conclusión de que Bolivia había eliminado los TDY como problema de salud pública de alcance nacional, pese a pruebas de que algunas comunidades aisladas de los Andes todavía carecían de una ingesta adecuada de yodo. El equipo hizo recomendaciones para mejorar el programa y garantizar su sostenibilidad. Asimismo, examinó los métodos de producción y el control de la calidad del proceso de yodación y recomendó medidas para reducir la variabilidad del contenido de yodo en la sal.

    In the year of 2003 the Brazilian government, as form of to stimulate the demand for natural gas in the country and to promote the success of the investment accomplished in the construction of the pipe line Bolivia-Brazil, it lowered the price of the Bolivian commodity' in US$0,85/MMBTU. In the end of 2005 and mainly in 2006, the current Bolivian president Evo Morales nationalized the energy reservations of your country. To main change it is related to the price of sale of the Bolivian input. The values stipulated in contract they were broken and new negotiations are in process. The maximum capacity of transport of natural gas was reached in 2007. However, before the crisis established due to the measure taken by the government from Bolivia, Brazil suspended the investments in compressors and the projections of increase of this capacity were stagnated. One of the forecasts was to increase in at least more 50% of the current capacity or even in 100% in a more promising scenery. Before this context this research makes the analysis of economical viability regarding the construction of the pipe line Bolivia-Brazil in agreement with three sceneries. The first of them suggests that the investments foreseen in compressors it was stopped and, this way, the pipe line will operate it ties the end of the amortization with your current maximum capacity. The second scenery already suggests that the investments were not interrupted, in other words, the current maximum capacity was overcome in 50%. Similarly to the previous ones, the third scenery makes reference the overrun of the current capacity in 100%. The methodology used for such an analysis it was lent of the financial mathematics and it is treated of the calculation of TIR and of VPL. Both studies show that in agreement with TIR (15%) and VPL the economical viability is satisfactory. The president of PETROBRAS is renegotiating the contract and the investments will probably be retaken. This measured it seeks to

    Full Text Available This article demonstrates that Bolivia - despite the negotiations of 1895 and all the recent rhetoric - was not worried of the effective recovery of the coast until long after the signing of the 1904 Treaty, instead of that, the presidency of Ismael Montes and the rise of Liberals in the Bolivian state, prioritized the modernization of the country and the search for ways to get the production of tin at any cost, at that time, the main wealth of Bolivia. This text has the purpose of explaining –as a witness of the time-, what were the reasons that the Bolivian authorities wielded before their people to sign the Treaty of Peace with Chile. Following that logic and notwithstanding all the recent literature, it seems appropriate to go beyond the subjective line of interpretation to establish the sayings of the main actors.

    Full Text Available From Enron to Evo is a long-term study of Enron and Shell’s construction of the Cuiabá pipeline in eastern Bolivia. The pipeline goes through the middle of the Chiquitano forest and affects a population of about 8,000. The project also has a negative impact on four critical ecoregions; the Gran Chaco and Cerrado, which are a mixture of grasslands and scattered trees, the Chiquitano dry forest, and the Pantanal wetlands. The Cuiabá pipeline has been highly contested by the thirty-four Chiquitano and two Ayoreo communities that live in the area. After years of field research, extensive interviews and document analyses, Dr. Hindery manages to expose the murky ways in which the hydrocarbon industry works in Bolivia. This is an industry where the powerful –mainly multinational oil companies and the Bolivian government– abuse the ecoregion and the indigenous populations that live on it.

    2014-01-01

    The present article proposes an analysis of the USA-Bolivia relationships in the health sector between 1971 and 2010 based on a grey and scientific literature review and on interviews. We examined United States Agency for International Development (USAID) interventions, objectives, consistency with Bolivian needs, and impact on health system integration. USAID operational objectives--decentralization, fertility and disease control, and maternal and child health--may have worked against each other while competing for limited Ministry of Health resources. They largely contributed to the segmentation and fragmentation of the Bolivian health system. US cooperation in health did not significantly improve health status while the USAID failed to properly tackle anti-drugs, political, and economic US interests in Bolivia.

    The goal of this study was to determine the health effects of living downstream from mines in the Potosí region of Bolivia. Histories, physical examinations, and urinalyses were completed on adults recruited from mining and nonmining villages in Bolivia. Blood concentrations of Cd, Hg, and Pb were determined in a subset of participants. Multiple logistic regression analyses were performed. Mining region participants had significantly higher frequencies of hypertension, hematuria, and ketonuria. Hematuria was significantly elevated among those watering livestock downstream from mines and eating grains from their own farm (odds ratio = 4.3; 95% confidence interval, 1.1 to 17.7). Significantly higher blood concentrations of Pb were observed in a subsample of participants with hematuria (4.80 μg/dL vs 10.91 μg/dL; P = 0.026). Efforts to abate environmental exposure to toxic metals seem warranted.

  9. Stereo Pair with ASTER Image, Iturralde Structure, Bolivia

    Science.gov (United States)

    2002-01-01

    An 8-kilometer (5-mile) wide crater of possible impact origin is shown in this stereoscopic view of an isolated part of the Bolivian Amazon. The view is derived from an Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) satellite image and a Shuttle Radar Topography Mission (SRTM) elevation model. The circular feature covering much of the image, known as the Iturralde Structure, is possibly the Earth's most recent 'big' impact event recording collision with a meteor or comet that might have occurred between 11,000 and 30,000 years ago.Although the structure was identified on satellite photographs in the mid-1980s, its location is so remote that it has only been visited by scientific investigators twice, most recently by a team from NASA's Goddard Space Flight Center in September 2002. Lying in an area of very low relief, the landform is a quasi-circular closed depression only about 20 meters (66 feet) in depth, with sharply defined sub-angular 'rim' materials. It resembles a 'cookie cutter' in that its appearance 'cuts' the heavily vegetated soft-sediments and pampas of this part of Bolivia. The SRTM data have provided investigators with the first topographic map of the site and will allow studies of its three-dimensional structure crucial to determining whether it actually is of impact origin.This stereoscopic image was generated by first draping the ASTER satellite image over the Shuttle Radar Topography Mission digital elevation model. Two differing perspectives were then calculated, one for each eye. They can be seen in 3-D by viewing the left image with the right eye and the right image with the left eye (cross-eyed viewing) or by downloading and printing the image pair and viewing them with a stereoscope. When stereoscopically merged, the result is a vertically exaggerated view of Earth's surface in its full three dimensions.Thick vegetation in part defines the surface that the SRTM radar sees as it maps the terrain.

    The presence and influence of nongovernmental organizations (NGOs) in the landscape of global health and development have dramatically increased over the past several decades. The distribution of NGO activity and the ways in which contextual factors influence the distribution of NGO activity across geographies merit study. This paper explores the distribution of NGO activity, using Bolivia as a case study, and identifies local factors that are related to the distribution of NGO activity across municipalities in Bolivia. The research question is addressed using a geographic information system (GIS) and multiple regression analyses of count data. We used count data of the total number of NGO projects across Bolivian municipalities to measure NGO activity both in general and in the health sector specifically and national census data for explanatory variables of interest. This study provides one of the first empirical analyses exploring factors related to the distribution of NGO activity at the national scale. Our analyses show that NGO activity in Bolivia, both in general and health-sector specific, is distributed unevenly across the country. Results indicate that NGO activity is related to population size, extent of urbanization, size of the indigenous population, and health system coverage. Results for NGO activity in general and health-sector specific NGO activity were similar. The uneven distribution of NGO activity may suggest a lack of co-ordination among NGOs working in Bolivia as well as a lack of co-ordination among NGO funders. Co-ordination of NGO activity is most needed in regions characterized by high NGO activity in order to avoid duplication of services and programmes and inefficient use of limited resources. Our findings also indicate that neither general nor health specific NGO activity is related to population need, when defined as population health status or education level or poverty levels. Considering these results we discuss broader implications

Un aspecto de estas dificultades fue la aparición de discursos nacionalistas y regionalistas, los cuales dividían la parte oriental de la parte occidental del país, y al revés. Dichos discursos se han caracterizado por sus fuertes matices étnicos y acentuaban por un lado la identidad camba y por otro la identidad colla. No obstante, tales discursos tienen raíces muy distintas y reflejan proyectos y relaciones de clase muy diferentes. Partiendo de la metáfora de la «nevera al revés» (la nevera que genera calor hacia dentro y frío hacia afuera, este artículo busca elucidar la interrelación entre la política nacionalista/regionalista, la etnia y la clase social en la Bolivia contemporánea.ABSTRACT: Over the past years Bolivia has seen a series of «social convulsions». One aspect of these upheavals was the emergence of nationalist and regionalist discourses pitting the orient against the occident of the country, and vice versa. Such discourses were marked by strong ethnic overtones, accentuating either camba or colla identities. Nevertheless, such identity discourses have very different roots and reflect very different projects and class relations. Taking a lead from the «inverted fridge» metaphor –the fridge that generates warmth towards the «inside(r» and cold towards the «outside(r»– this paper seeks to elucidate the interrelation between the politics of nationalism/regionalism, ethnicity and class in contemporary Bolivia.

    2014-01-01

    The objective of the RAFT-Altiplano project (RAFT: Réseau en Afrique Francophone pour la Télémédecine, or African Francophone Telemedicine Network) is to evaluate the viability, potential, and risks of implementing and developing a telemedicine network in the context of a developing country-specifically, the Altiplano region of Bolivia-to improve access to medical care and continuing education in a rural area. The activities described in this report took place between 2011 and 2013. Digital telemedicine equipment was donated to the health centers and a Microsoft®-based platform capable of integration with other technologies (using standardized formats) was developed to manage documents and clinical content electronically. Health professionals were trained in teleconsultation and the teleconsultation workflow was designed. The tele-education system used is Dudal, which requires only a small bandwidth. After three years of implementation, an organized working structure of teleconsultation and tele-education tools, adapted to the Latin American context, is now in place and connections have been established with hospitals, institutions, and health centers. The project has improved access to specialized medical care in remote health centers and third-level hospitals in urban areas, and it has become the foundation for development of the national project "TeleSalud for Bolivia" promoted by the Ministry of Health, which involves use of the new Bolivian satellite, Túpac Katari. It is viable to develop and set up telemedicine tools to serve the population in remote regions of Bolivia when they are made available to government and municipal health institutions and communication between them and the health centers takes place in a coordinated manner. The sharing of experiences, challenges, and risks encountered is very useful in designing and implementing the telemedicine project "TeleSalud for Bolivia" on a national scale.

    Full Text Available Chagas disease is one of the main public health problems in Latin America. Since the available treatments for this disease are not effective in providing cure, the screening of potential antiprotozoal agents is essential, mainly of those obtained from natural sources. This study aimed to provide an evaluation of the trypanocidal activity of 92 ethanol extracts from species belonging to the families Annonaceae, Apiaceae, Cucurbitaceae, Lamiaceae, Lauraceae, Moraceae, Nyctaginaceae, and Verbenaceae against the Y and Bolivia strains of Trypanosoma cruzi. Additionally, cytotoxic activity on LLCMK2 fibroblasts was evaluated. Both the trypanocidal activity and cytotoxicity were evaluated using the MTT method, in the following concentrations: 500, 350, 250, and 100 µg/mL. Benznidazole was used for positive control. The best results among the 92 samples evaluated were obtained with ethanol extracts of Ocotea paranapiacabensis (Am93 and Aegiphila lhotzkiana (Am160. Am93 showed trypanocidal activity against epimastigote forms of the Bolivia strain and was moderately toxic to LLCMK2 cells, its Selectivity Index (SI being 14.56, while Am160 showed moderate trypanocidal activity against the Bolivia strain and moderate toxicicity, its SI being equal to 1.15. The screening of Brazilian plants has indicated the potential effect of ethanol extracts obtained from Ocotea paranapiacabensis and Aegiphila lhotzkiana against Chagas disease.

    Full Text Available Unregulated selling practices, bad storage habits and the use of illegal pesticides in Bolivia are widespread, with increasing negative consequences on public health and the environment. The present study describes the selling, storage and use of legal, illegal and obsolete pesticides among pesticide retailers and farmers in Bolivia. A cross-sectional study was conducted on 191 pesticide-using farmers and 40 pesticide retailers. Data were gathered in 2009 in La Paz County, Bolivia. A questionnaire was used to evaluate pesticide handling practices and observational data on pesticide stocks and storage was assessed through direct visits on site. Banned, outdated and highly toxic pesticides were found stored on most smallholder farms. A mean of 299 g of pesticides was found on each farm, of which 60% were obsolete. Knowledge on pesticide toxicity and safe handling practices were lacking among both retailers and farmers, and poisonings were frequently reported. Significant figures of obsolete pesticides were found outside of the officially recognized dumping sites. This underlines the necessity of including the small but numerous amounts of pesticides stored at farms, when calculating a country’s total amount of obsolete pesticides. Better regulations of imports, sale and storage and an improved use of safety measures when handling pesticides needs to be urgently addressed.

    Global coverage with three doses of the diphtheria, tetanus and pertussis vaccine (DTP3) increased from less than 5% in 1974 to 82% in 2009 due to worldwide focus on universal vaccination. Nonetheless, pertussis remains the fifth-leading cause of vaccine-preventable deaths. This study examines DTP3 vaccination from 1980 through 2009 in three countries within Latin America, Bolivia, Brazil and Mexico, selected for their distinct health care systems and vaccination strategies. Similar to global trends, these nations have achieved dramatic improvements in pertussis immunization. In Bolivia, immunization rates increased from 11% to 85%; in Brazil, rates increased from 37% to 97%; and in Mexico, the immunization rates increased from 44% to 72%. Pertussis infections have concomitantly decreased from 1980 to 2009. In Bolivia, cases decreased from 44.4 per 100,000 people to zero reported cases. In Brazil, the incidence decreased from 37.6 to 0.5 cases per 100,000. The incidence in Mexico decreased from 8.2 to 0.5 cases per 100,000. In order to increase vaccination rates further, health systems must continue to raise awareness about disease prevention, expand health surveillance systems, and improve access to health services.

    Full Text Available This article examines the implications of natural gas developmentfor Guaraní indigenous communities in southeastern Bolivia. Duringthe 1990s, the Bolivian government enacted a series of neoliberalreforms designed to attract international investment for natural gasand petroleum exploitation and to facilitate the export of hydrocarbons.Protests over the management and distribution of the benefitsderived from natural gas contributed diretly to the election of EvoMorales, Bolivia´s first indigenous president. Nevertheless, anddespite the pro-indigenous discourse of Morales and his MAS (Movementto Socialism party, gas production has had negative effectsfor indigenous peoples in Bolivia´s Chaco region, who are directlyimpacted by extractive activities. This article examines the case ofthe Guaraní people of the Tierra Comunitaria de Orígen (OriginaryCommunal Land, TCO Itika Guasu, in Tarija department, whereRepsol´s Margarita ´mega-field´ is located. It is argued here thatgas exploitation in Guaraní territory has been conducted withoutadequate prior consultation or meaningful participation of thepopulations affected.

    Acute respiratory infections represent a serious public health issue worldwide but virological aetiologies of Influenza Like Illnesses (ILIs) remain largely unknown in developing countries. This study represents the first attempt to characterise viral aetiologies of ILIs in Bolivia. It was performed in Santa Cruz city from January 2010 to September 2012, based on 564 naso-pharyngeal swabs collected in a National Reference Laboratory and real-time PCR techniques, viral cultures and phylogenetic analyses. 50.2% of samples were positive for at least one virus with influenza viruses (Flu A: ~15%; Flu B: ~9%), rhinoviruses (~8%), coronaviruses (~5%) and hRSV (~4%) being the most frequently identified. The pattern of viral infections varied according to age groups. The elucidation rate was the highest (>60%) amongst patients under 10 yo and the lowest (Bolivia in the study period, originating from Central and North America, Europe, Asia and Australia. Our results emphasise the requirement for a reinforced epidemiological and genetic follow-up of influenza and other ILIs in Bolivia to further inform the preparation of vaccines used in the region, guide vaccination campaigns and improve the medical management of patients.

    Indigenous peoples have the worst socio-demographic indicators and the largest inequalities in terms of access to social services and health in the Latin American region, Bolivia included. In the last few years, attempts to implement policies that support indigenous people's health rights led to the development of intercultural health approaches. Yet, acceptance and integration of indigenous medicine into the biomedical health system presents a major challenge to intercultural health in Latin America. The objective of this article is to analyze the case of a health center in Tinguipaya, one of the first and few examples of intercultural health initiatives in Bolivia. This intercultural health project, which represents a pioneer experience with regard to the creation of intercultural health services in Bolivia, aims to create a network between local communities, traditional healers, and biomedical staff and offer a more culturally sensitive and holistic health service for indigenous people living in the area. The aim of this article is to critically assess this initiative and to analyze the main challenges met in the creation of a more effective intercultural health policy. The extent to which this initiative succeeded in promoting the integration between indigenous health practitioners and biomedical staff as well as in improving access to health care for local indigenous patients will also be examined.

    Abstract Yellow fever (YF) is a serious public health problem in Bolivia since at least the 19th century. Surprisingly, very limited information has been made available to date regarding the genetic characterisation and epidemiology of Bolivian YF virus (YFV) strains. Here, we conducted the genetic characterization of 12 human isolates of YFV collected in Bolivia between 1999 and 2008, by sequencing and analysis of two regions of the viral genome: a fragment encoding structural proteins “PrM” (premembrane and envelope) and a distal region “EMF,” spanning the end of the virus genome. Our study reveals a high genetic diversity of YFV strains circulating in Bolivia during the last decade: we identified not only “Peruvian-like” genotype II viruses (related to previously characterized Bolivian strains), but also, for the fist time, “Brazilian-like” genotype I viruses. During the complete period of the study, only cases of “jungle” YF were detected (i.e., circulation of YFV via a sylvatic cycle) with no cluster of urban cases. However, the very significant spread of the Aedes aegypti mosquito across Bolivian cities threatens the country with the reappearance of an urban YFV transmission cycle and thus is required a sustained epidemiological surveillance.

  13. The role of civil society organizations in the institutionalization of indigenous medicine in Bolivia.

    2014-12-01

    December 2013 marked a significant shift in Bolivia with the enactment of a law for the inclusion of indigenous doctors in the National Health System. This article traces the constellation of forces that led to the institutionalization of indigenous medicine in Bolivia. It identifies three factors contributing to this health policy change. The first factor is the crystallization of a strong indigenous movement fighting for the recognition of cultural rights through the foundation of civil society organizations. Second is the rise to power of Evo Morales, the first Latin American president of indigenous origin, who has promoted multicultural policies, formally supported through the promulgation of a new constitution. Lastly is the influence of the global acceptance of alternative medicine. Indigenous doctor organizations in Bolivia have been highly involved throughout the entire process of institutionalization and have played a crucial role in it. An analysis of the relationship between these civil society organizations and the Bolivian government reveals a strong partnership. This dynamic can be described in terms of Interdependence Theory, as each party relied on the other in the promotion and practice of the law to achieve the integration of indigenous medicine as part of the Bolivian Health System.

    Bolivia ranks among the 10 Latin American countries with the highest rates of tuberculosis (TB) and multidrug resistant (MDR) TB. In view of this, and of the lacking information on the population structure of Mycobacterium tuberculosis in the country, we explored genotype associations with drug resistance and clustering by analyzing isolates collected in 2010 from 100 consecutive TB patients at risk of drug resistance in seven of the nine departments in which Bolivia is divided. Fourteen isolates were MDR, 29 had other drug resistance profiles, and 57 were pansusceptible. Spoligotype family distribution was: Haarlem 39.4%, LAM 26.3%, T 22.2%, S 2.0%, X 1.0%, orphan 9.1%, with very low intra-family diversity and absence of Beijing genotypes. We found 66 different MIRU-VNTR patterns; the most frequent corresponded to Multiple Locus Variable Analysis (MLVA) MtbC15 patterns 860, 372 and 873. Twelve clusters, each with identical MIRU-VNTR and spoligotypes, gathered 35 patients. We found no association of genotype with drug resistant or MDR-TB.

However, results should be taken cautiously because the sample is small and includes a particular subset of M. tuberculosis population. Copyright © 2013 Elsevier B.V. All rights reserved.

    Young adults 18 to 25 years old show the highest prevalence of marijuana use in Latin America. This study analyzes the changes in prevalence of marijuana use among university students in the Andean Community (Bolivia, Colombia, Ecuador, and Peru) from two studies carried out in 2009 and in 2012. Data were collected through representative two-stage samples of universities and students in the Andean Community. An online survey was administered using a standardized questionnaire. Prevalence was calculated for lifetime, past year, and past month. Marijuana was the most widely used illicit substance consumed among university students, in 2009 and in 2012. Past month prevalence among university students in 2009 in Colombia was 5.27%, in Peru 1.00%, in Ecuador 1.68%, and in Bolivia 0.76%. Past month prevalence in 2012 in Colombia was 7.14%, in Ecuador 3.67%, in Peru 1.62%, and in Bolivia 1.45% in 2012. Among university students in the Andean Community, past month prevalence increased among both males and females between 2009 and 2012 in most countries. Marijuana continues to be the most commonly used illicit drug in Latin American countries. Increases in prevalence among young adults could have important implications for national drug policy.

    The Bolivia-Brazil Natural Gas Pipeline has 2.593 kilometers since Rio Grande City in Bolivia until Canoas City, in south Brazil. The pipeline crosses a lot of types of geological fields and difficult topography. The south spread of the gas pipeline is the most interesting because of its hard topography combined with the variety of geological materials, such as, colluvium deposits and debris flow areas. Curriola River is located at the kilometer 408, north part of Parana State. In this area, the pipeline crosses slopes of 45 degrees of inclination. The down part of Curriola's slope is composed by a non-resistance material (clay and little rock blocks) with a high porosity. Every year, during the rainy seasons, tension cracks are observed evidencing the earth movement. The slope stability is above the minimum expected for pipeline operation. The aim of this paper is to present the site characterization of the Curriola River Slope, together with all the investigation made in order to supply the studies with condensed information for the slope stabilization.

    Full Text Available This essay relates improvements in social indicators in Bolivia during the Twentieth Century to ideological changes during the same period. During the Twentieth Century, most social indicators improved dramatically in Bolivia. Separately, scholars have vigorously debated ideologies, such as neoliberalism and its macroeconomic competitors, and the potential social impact of these ideologies. Despite the separate emphases on ideas and social outcomes, no systematic attempt has been made by scholars of Bolivia to link long–term ideological change to long–term social improvement in the country. This essay argues that it is probable that such a relationship exists, but it is important to consider mass ideology, which affects the whole of Bolivian society, in addition to elite ideology, which affects a much more limited portion of society.Este ensayo relaciona las mejoras en indicadores sociales en Bolivia durante el siglo XX con cambios ideológicos registrados durante el mismo periodo. Durante el siglo XX la mayoría de los indicadores sociales mejoraron dramáticamente en Bolivia. Los especialistas han debatido vigorosamente  la relación de estas mejoras con ideologías tales como el neoliberalismo y sus competidores macroeconómicos, discutiendo su potencial impacto social. Sin embargo, pese al énfasis otorgado a la relación de las ideas con los resultados sociales, no ha habido ninguna tentativa sistemática por parte de los especialistas de  relacionar el cambio ideológico de largo plazo con las mejoras sociales de largo plazo en el país. Este ensayo sostiene que es probable que tal relación exista, pero para visibilizarla es importante considerar la ideología de masas, que afecta al conjunto de la sociedad boliviana, además de la ideología de la élite, que afecta a una porción mucho más limitada de la sociedad.

    Bolivia, one of the poorest countries in the world, ranks 108th on the 2013 Human Development Index. With approximately 1 neurosurgeon per 200,000 people, access to neurosurgery in Bolivia is a growing health concern. Furthermore, neurosurgery in nonindustrialized countries has been considered both cost-prohibitive and lacking in outcomes evaluation. A non-governmental organization (NGO) supports spinal procedures in Bolivia (Solidarity Bridge), and the authors sought to determine its impact and cost-effectiveness. In a retrospective review of prospectively collected data, 19 patients were identified prior to spinal instrumentation and followed over 12 months. For inclusion, patients required interviewing prior to surgery and during at least 2 follow-up visits. All causes of spinal pathology were included. Sixteen patients met inclusion criteria and were therefore part of the analysis. Outcomes measured included assessment of activities of daily living, pain, ambulation, return to work/school, and satisfaction. Cost-effectiveness was determined by cost-utility analysis. Utilities were derived using the Health Utilities Index. Complications were incorporated into an expected value decision tree. Median (± SD) preoperative satisfaction was 2.0 ± 0.3 (on a scale of 0-10), while 6-month postoperative satisfaction was 7 ± 1.4 (p Bolivia appears to be cost-effective, especially when compared with the conventional $50,000/QALY benchmark and the WHO endorsed country-specific threshold of $16,026/QALY. However, with a gross domestic product per capita in Bolivia equaling $4800 per year and 30.3% of the population living on less than $2 per day, this cost continues to appear unrealistic. Additionally, the study has several significant limitations, namely its limited sample size, follow-up period, the assumption that patients not receiving surgical intervention would not make any clinical improvement, the reliance on the NGO for patient selection and sustainable practices

    Between the 16th and 18th centuries, Aedes aegypti (Diptera: Culicidae), a mosquito native to Africa, invaded the Americas, where it was successively responsible for the emergence of yellow fever (YF) and dengue (DEN). The species was eradicated from numerous American countries in the mid-20th century, but re-invaded them in the 1970s and 1980s. Little is known about the precise identities of Ae. aegypti populations which successively thrived in South America, or their relation with the epidemiological changes in patterns of YF and DEN. We examined these questions in Bolivia, where Ae. aegypti, eradicated in 1943, re-appeared in the 1980s. We assessed the genetic variability and population genetics of Ae. aegypti samples in order to deduce their genetic structure and likely geographic origin. Using a 21-population set covering Bolivia, we analyzed the polymorphism at nine microsatellite loci and in two mitochondrial DNA regions (COI and ND4). Microsatellite markers revealed a significant genetic structure among geographic populations (F(ST)=0.0627, PBolivia. Analysis of mtDNA sequences revealed the existence of two genetic lineages, one dominant lineage recovered throughout Bolivia, and the second restricted to rural localities in South Bolivia. Phylogenic analysis indicated that this minority lineage was related to West African Ae. aegypti specimens. In conclusion, our results suggested a temporal succession of Ae. aegypti populations in Bolivia, that potentially impacted the epidemiology of dengue and yellow fever. Copyright © 2012 Elsevier B.V.

    The analysis of drainage net allows to identify features of relief symmetry and/or not symmetry and know its morpho structure (high and low structural). The interpretation of relief and drainage texture elements at Landsat/ETM7+ satellite images allows to identify the geo environmental zoning. The integration between morpho structural maps and geo environmental zones maps produces sustainable capacity maps. In the Bolivia-Brazil Gas Pipeline influence area, the evaluation of sustainable capacity shapes the interrelation among gas pipeline and physical environment and allows classify more geological and geotechnical favorable areas to gas pipeline maintenance. Gas pipeline regions located at 'High Sustainable Capacity' need few maintenance. However, gas pipeline regions at 'Low/Very Low Sustainable Capacity' need constant investment and monitoring.

    Wild populations of Triatoma infestans, the main vector of Chagas disease in the Southern Cone countries, may be involved in reinfestation of human dwellings, limiting the success of vector-control campaigns in Bolivia. Knowledge of the distribution of these populations remains incomplete. We report here the detection of T. infestans wild populations in large areas in the department of La Paz, Bolivia. Among 18 sylvatic areas investigated, 17 were positive with T. infestans specimens. The infection rate of captured T. infestans with Trypanosoma cruzi was 85.7% in adult specimens. These results expand the geographical distribution of wild populations of T. infestans; it may be distributed throughout the Inter-Andean Dry Forest eco-region of Bolivia. The current information allows us to propose the hypothesis that a sylvatic origin of the reinfestation is located in the valleys of La Paz. PMID:20348501

    Full Text Available For most crops, like Capsicum, their diversity remains under-researched for traits of interest for food, nutrition and other purposes. A small investment in screening this diversity for a wide range of traits is likely to reveal many traditional varieties with distinguished values. One objective of this study was to demonstrate, with Capsicum as model crop, the application of indicators of phenotypic and geographic diversity as effective criteria for selecting promising genebank accessions for multiple uses from crop centers of diversity.

    Soils near artisanal and small-scale gold mines (ASGM) have high arsenic (As) contents due to the presence of arsenopyrite in gold ores and accelerated accumulations due to mine wastes disposal practices and other mining activities. We determined the content and speciation to understand the fate and environmental risks of As accumulations in 24 bulk and 12 rhizosphere soil samples collected in the Virgen Del Rosario and the Rayo Rojo cooperative mines in the highlands of Bolivia. Mean total As contents in bulk and rhizosphere soils ranged from 13 to 64 mg kg(-1) and exceeded the soil environmental quality guidelines of Canada. Rhizosphere soils always contained at least twice the As contents in the bulk soil. Elemental mapping using 4×5 μm synchrotron-generated X-ray micro-beam revealed As accumulations in areas enriched with Fe. Results of As-X-ray Absorption Near Edge Spectroscopy (As-XANES) showed that only As(V) species was detectable in all samples regardless of As contents, size fractions and types of vegetation. Although the toxicity of As(V) is less than As(III), we suggest that As uptake of commonly-grazed vegetation by alpaca and llama must be determined to fully understand the environmental risks of high As in soils near ASGM in Bolivia. In addition, knowledge on the speciation of the As bio-accessible fraction will provide another useful information to better understand the fate and transfer of As from soils into the food chain in environments associated with the ASGM in Bolivia and other parts of the world.

    Over the last few decades, pyrethroid-resistant in Triatoma infestans populations have been reported, mainly on the border between Argentina and Bolivia. Understanding the genetic basis of inheritance mode and heritability of resistance to insecticides under laboratory conditions is crucial for vector management and monitoring of insecticide resistance. Currently, few studies have been performed to characterize the inheritance mode of resistance to pyrethroids in T. infestans; for this reason, the present study aims to characterize the inheritance and heritability of deltamethrin resistance in T. infestans populations from Bolivia with different toxicological profiles. Experimental crosses were performed between a susceptible (S) colony and resistant (R) and reduced susceptibility (RS) colonies in both directions (♀ x ♂ and ♂ x ♀), and inheritance mode was determined based on degree of dominance (DO) and effective dominance (D(ML)). In addition, realized heritability (h(2)) was estimated based on a resistant colony, and select pressure was performed for two generations based on the diagnostic dose (10 ng. i. a. /nymph). The F1 progeny of the experimental crosses and the selection were tested by a standard insecticide resistance bioassay. The result for DO and D(ML) (Bolivia. The lethal doses (LD50) increase from one generation to another rapidly after selection pressure with deltamethrin. This suggests that resistance is an additive and cumulative factor, mainly in highly structured populations with limited dispersal capacity, such as T. infestans. This phenomenon was demonstrated for the first time for T. infestans in the present study. These results are very important for vector control strategies in problematic areas where high resistance ratios of T. infestans have been reported.

    The prevalence of infection with the three common soil-transmitted helminths (i.e. Ascaris lumbricoides, Trichuris trichiura, and hookworm) in Bolivia is among the highest in Latin America. However, the spatial distribution and burden of soil-transmitted helminthiasis are poorly documented. We analysed historical survey data using Bayesian geostatistical models to identify determinants of the distribution of soil-transmitted helminth infections, predict the geographical distribution of infection risk, and assess treatment needs and costs in the frame of preventive chemotherapy. Rigorous geostatistical variable selection identified the most important predictors of A. lumbricoides, T. trichiura, and hookworm transmission. Results show that precipitation during the wettest quarter above 400 mm favours the distribution of A. lumbricoides. Altitude has a negative effect on T. trichiura. Hookworm is sensitive to temperature during the coldest month. We estimate that 38.0%, 19.3%, and 11.4% of the Bolivian population is infected with A. lumbricoides, T. trichiura, and hookworm, respectively. Assuming independence of the three infections, 48.4% of the population is infected with any soil-transmitted helminth. Empirical-based estimates, according to treatment recommendations by the World Health Organization, suggest a total of 2.9 million annualised treatments for the control of soil-transmitted helminthiasis in Bolivia. We provide estimates of soil-transmitted helminth infections in Bolivia based on high-resolution spatial prediction and an innovative variable selection approach. However, the scarcity of the data suggests that a national survey is required for more accurate mapping that will govern spatial targeting of soil-transmitted helminthiasis control.

    Heffernan, Claire; Thomson, Kim; Nielsen, Louise

    2008-05-02

    The paper explores the low uptake of livestock vaccination among poor farming communities in Bolivia utilising core elements of the original innovation diffusion theory. Contrary to the recent literature, we found that vaccination behaviour was strongly linked to social and cultural, rather than economic, drivers. While membership in a group increased uptake, the 'hot' and 'cold' distinctions which dictate health versus illness within Andean cosmology also played a role, with vaccination viewed as a means of addressing underlying imbalances. We concluded that uptake of livestock vaccination was unlikely to improve without knowledge transfer that acknowledges local epistemologies for livestock disease.

    Full Text Available This study examined environmental and socioeconomic outcomes of a water project in rural Bolivia, and sought insights on how and why its planning was so flawed. The project destroyed an ancient, sustainable irrigation system, and replaced it with one that provides insufficient and diminishing quantities of water to many fewer people, appears to be causing land degradation and groundwater depletion, and has fueled conflicts. The study shows that even relatively small, NGO-led projects can generate significant negative impacts, and raises questions about the pressures on development agencies to charge ahead with projects, despite obvious potential for such impacts.

  16. Culture and landslide risk in the Central Andes of Bolivia and Peru

    2009-06-01

    Full Text Available Culture and its heritage play a major role in determining landslide risk in the Central Andes. Examples of some of these many possible influences are provided from natural and social science literature and from the author’s recent work in Bolivia. Landslide risk appears to have generally increased throughout the last millennium, due largely to anthropogenic modification of hazard, exposure, vulnerability and coping capacity. These changes result from both local and distant pressures and from contemporaneous and pervious cultural factors. Consequently, holistic examination of landslide risk necessitates consideration of culture and its heritage.

    A low-power microscope-based cytological system to assess the quality of expectorated sputum provided for tuberculosis (TB) diagnosis was piloted in Bolivia. A total of 3688 samples were subjected to visual and cytological examination in nine laboratories: of these, 591 (16%) were misclassified by visual examination and 294 (8%) were found to be degraded. The degree of discordance varied between locations, and laboratories received a higher number of degraded specimens from isolated health clinics. Cytological assessment of sputum was found to be feasible and identified areas for improvement in the Bolivian diagnostic system for TB.

    This work aims the economics and the viability of Natural Gas Industrialization in Bolivia, by producing secondary fuels like gas to liquid (GTL)-diesel from natural gas (cleaner than the oil by-product), looking for a clean development with that environmentally well energy using this GTL process. Bolivia has resources that could fulfill these secondary energy resources from GTL. It is possible to process 30 MCMpd of gas obtaining profits from the gas and also from the liquid hydrocarbons that are found in it. Then the Bolivian GTL would present the following advantages: it would export diesel and/or gasoline and would not have to import it anymore.; the exportations of GTL-FT would reach 35 Mbpy, acquiring competitive prices; it would increase productive jobs not only due to the GTL itself, but also from secondary economy linked to GTL market; the use of GTL-FT diesel would bring a ''cleaner'' environment especially in the urban areas; finally, from the macroeconomic perspective, the investment in the plant construction and supporting works would generate a great amount of job offers.

    The effectiveness of rotavirus vaccine in the field may set the stage for a changing landscape of diarrheal illness affecting children worldwide. Norovirus and rotavirus are the two major viral enteropathogens of childhood. This study describes the prevalence of norovirus and rotavirus 2 years after widespread rotavirus vaccination in Cochabamba, Bolivia. Stool samples from hospitalized children with acute gastroenteritis (AGE) and outpatients aged 5–24 months without AGE were recruited from an urban hospital serving Bolivia's third largest city. Both viruses were genotyped, and norovirus GII.4 was further sequenced. Norovirus was found much more frequently than rotavirus. Norovirus was detected in 69/201 (34.3%) of specimens from children with AGE and 13/71 (18.3%) of those without diarrhea. Rotavirus was detected in 38/201 (18.9%) of diarrheal specimens and 3/71 (4.2%) of non-diarrheal specimens. Norovirus GII was identified in 97.8% of norovirus-positive samples; GII.4 was the most common genotype (71.4% of typed specimens). Rotavirus G3P[8] was the most prevalent rotavirus genotype (44.0% of typed specimens) and G2P[4] was second most prevalent (16.0% of typed specimens). This community is likely part of a trend toward norovirus predominance over rotavirus in children after widespread vaccination against rotavirus. PMID:26598569

    2012-11-01

    Eucalyptus globulus is one of the most planted species in the Inter-Andean Valleys of Bolivia, where growing conditions are different from most places where eucalyptus have been studied. This prevents a straightforward utilization of models fitted elsewhere. In this study a distance-independent individual-tree growth model for E. globulus plantations in Bolivia was developed based on data from 67 permanent sample plots. The model consists of sub-models for dominant height, tree diameter increment, height-diameter relationship and survival. According to model-based simulations, the mean annual increment with the optimal rotation length is about 13 m3 ha{sup -}1 yr{sup -}1 on medium-quality sites and 18 m{sup 3} ha{sup -}1 yr -1 on the best sites. A suitable rotation length for maximizing wood production is approximately 30 years on medium sites and 20 years on the most productive sites. The developed models provide valuable information for further studies on optimizing the management and evaluating alternative management regimes for the species. (Author) 22 refs.

Specifically, the article seeks to: (a identify some stylized facts that may help understand the divergence between Andean and Nordic countries; (b identify key historical processes that explain the divergent effect of natural resource abundance in Andean and Nordic economies. In order to achieve these objectives, four topics are covered: GDPpc, population, trade and taxation. The analysis comprises three Nordic countries (Finland, Norway and Sweden and three Andean countries (Bolivia, Chile and Peru from the mid-Nineteenth Century to present day.

    Full Text Available The article takes a historical look at the educational reforms implemented in Bolivia with reference to the formation of citizenship. For this purpose historical research was used and the bibliographic review was used to collect, describe and analyze the written sources. This in order to understand the relationship between State, education and citizenship, which identifies two aspects that guide educational policies and the formation of citizenship. In this way, we can also elucidate the types of citizens who projected these educational reforms in Bolivia during the 20th century: the liberal (1899-1920, the nationalist (1954-1964 and the neoliberal (1994-2004; And in the 21st century, the sociocommunity. In each of these reforms there are common characteristics, on the one hand, there is the centralization of public education at the hands of the State; On the other hand, the role given to education for civic formation and the construction of national identity, in this case Bolivianity; For example, for the indigenous majority was their assimilation to the national culture and homogenization, through education. Likewise, each reform sought the formation of a citizenship; In the case of the liberal raised the Bolivian identity; The nationalist point towards mestizaje as a citizen, neoliberal ideal for the construction of a pluricultural and multilingual citizenship; And the sociocommunity towards an intercultural and decolonized citizenship.

    The public health impact of rotavirus vaccination in countries with high child mortality rates remains to be established. The RV1 rotavirus vaccine was introduced in Bolivia in August 2008. This study describes the trends in deaths, hospitalizations, and healthcare visits due to acute gastroenteritis (AGE) and in rotavirus-related hospitalizations, among children rotavirus-related AGE was assessed using data from the active surveillance hospitals. Compared with the 2001-2008 pre-vaccine baseline, the mean number of rotavirus-related hospitalizations was reduced by 40.8% (95% confidence interval (CI) 21.7-66.4%) among children rotavirus disease. Over the post-vaccine period, changes in rotavirus epidemiology were observed, manifested by variations in seasonality and by a shift in the mean age of those with rotavirus infection. The significant decrease in main AGE-related health indicators in children rotavirus vaccine provides evidence of a substantial public health impact of rotavirus vaccination in Bolivia, as a measure for protecting children against AGE.

  18. Tenure Security and Land Appropriation under Changing Environmental Governance in Lowland Bolivia and Pará

    Directory of Open Access Journals (Sweden)

    Pablo Pacheco

    2015-02-01

    Full Text Available Appropriation of public lands associated with agricultural frontier expansion is a longstanding occurrence in the Amazon that has resulted in a highly skewed land-tenure structure in spite of recent state efforts to recognize tenure rights of indigenous people and smallholders living in or nearby forests. Growing concerns to reduce environmental impacts from agricultural development have motivated state governments to place greater attention on sustainable land management and forest conservation. This paper assesses the political and institutional conditions shaping tenure security and land appropriation in lowland Bolivia and the State of Pará in Brazil, and their links with environmental governance. The two cases show that clarifying and securing tenure rights is considered as the cornerstone for improving environmental governance. Thus, much attention has been given to the recognition of indigenous people and smallholder rights and to legalization of large-scale estates in agricultural frontiers, which have in turn influenced emerging conservation and environmental governance approaches. While policy frameworks share similar goals in the two cases, contrasting implementation approaches have been adopted: more agrarian in lowland Bolivia and more conservationist in the State of Pará.

    Full Text Available A small focus of hemorrhagic fever (HF cases occurred near Cochabamba, Bolivia, in December 2003 and January 2004. Specimens were available from only one fatal case, which had a clinical course that included fever, headache, arthralgia, myalgia, and vomiting with subsequent deterioration and multiple hemorrhagic signs. A non-cytopathic virus was isolated from two of the patient serum samples, and identified as an arenavirus by IFA staining with a rabbit polyvalent antiserum raised against South American arenaviruses known to be associated with HF (Guanarito, Machupo, and Sabiá. RT-PCR analysis and subsequent analysis of the complete virus S and L RNA segment sequences identified the virus as a member of the New World Clade B arenaviruses, which includes all the pathogenic South American arenaviruses. The virus was shown to be most closely related to Sabiá virus, but with 26% and 30% nucleotide difference in the S and L segments, and 26%, 28%, 15% and 22% amino acid differences for the L, Z, N, and GP proteins, respectively, indicating the virus represents a newly discovered arenavirus, for which we propose the name Chapare virus. In conclusion, two different arenaviruses, Machupo and Chapare, can be associated with severe HF cases in Bolivia.

    Summary Objectives Rotavirus is the most important etiology of severe diarrhea in Bolivia. The monovalent attenuated human oral rotavirus vaccine Rotarix® was introduced in Bolivia in 2008. We describe the molecular epidemiology of circulating rotavirus strains before vaccine introduction. Methods Two thousand one hundred thirty-five diarrheal samples were collected from hospitals in four Bolivian cities during 2007–2008. Forty-three percent (445 of 1030 rotavirus-positive samples) were analyzed for G and P genotypes. Among those, 331 were electropherotyped by polyacrylamide gel electrophoresis. Disease severity was quantified using a modified Vesikari scale. Results Among the 445 samples, five genotypes were found to be prevalent: G9P[8] (33%), G1P[6] (17%), G2P[4] (13%), G9P[6] (12%), and G1P[8] (4%). Co-infections with two or more strains accounted for 14% of samples. The most prevalent strain, G9, showed greater electropherotype diversity compared to other serogroups. Strain G1P[6] generally infected younger children and peaked later in the year than other strains. No particular genotype was associated with a higher severity score, though there was a significant difference in the duration of diarrhea between genotypes. Conclusions During the 2-year pre-vaccine period, substantial diversity of rotavirus co-circulating strains was observed. These data constitute a baseline against which changes in circulating strains post-vaccine introduction can be monitored. PMID:23688547

    The role of pollen flow within and between cultivated and wild tropical crop species is little known. To study the pollen flow of cacao, we estimated the degree of self-pollination and pollen dispersal distances as well as gene flow between wild and cultivated cacao (Theobroma cacao L.). We studied pollen flow and genetic diversity of cultivated and wild cacao populations by genotyping 143 wild and 86 cultivated mature plants and 374 seedlings raised from 19 wild and 25 cultivated trees at nine microsatellite loci. A principal component analysis distinguished wild and cultivated cacao trees, supporting the notion that Bolivia harbors truly wild cacao populations. Cultivated cacao had a higher level of genetic diversity than wild cacao, presumably reflecting the varied origin of cultivated plants. Both cacao types had high outcrossing rates, but the paternity analysis revealed 7-14% self-pollination in wild and cultivated cacao. Despite the tiny size of the pollinators, pollen was transported distances up to 3 km; wild cacao showed longer distances (mean = 922 m) than cultivated cacao (826 m). Our data revealed that 16-20% of pollination events occurred between cultivated and wild populations. We found evidence of self-pollination in both wild and cultivated cacao. Pollination distances are larger than those typically reported in tropical understory tree species. The relatively high pollen exchange from cultivated to wild cacao compromises genetic identity of wild populations, calling for the protection of extensive natural forest tracts to protect wild cacao in Bolivia.

    The objective of this study is to determine the prevalence of abuse of vulnerable older persons in the family and community environment in the following regions-Spain (Andalusia-Córdoba), Portugal (Azores), and Bolivia (Santa Cruz de la Sierra)-and to identify risk factors and delineate a profile of abused older persons. For this, a descriptive cross-sectional study was conducted. The sample consisted of people in the age group 65 years plus living in the catchment areas of health centers. The following were used as instruments to collect data: the medical record of the patients of relevant health centers, Mini-Mental State Examination (MMSE), daily activities autonomy test, adaptability, partnership, growth, affection, and resolve (APGAR) familiar test, The Elder Abuse Suspicion Index (EASI) and the Social Work Evaluation Form. Multivariable logistic regression was performed to identify factors associated with abuse. Suspected abuse was identified in 6.9% of the elderly who participated in the study in Spain, 39% in Bolivia, and 24.5% in Azores. In all areas, studied psychological abuse was the most common type of abuse. In conclusion, although the prevalence of abuse to older people in the family and community environment differs in the areas studied, it is present in all countries and the data are comparable with other developing and European countries. The profile of the abused older persons appears to be similar in all countries.

    Triatoma infestans is the main vector of Chagas disease in the southern cone countries. Present control strategies based on indoor and outdoor residual insecticide spraying are not sufficient to control disease transmission, particularly in Bolivia. Techniques based on the management of the human environment may be good alternatives or supplements. Social and entomological surveys were carried out in four villages of Bolivia situated in the dry inter-Andean Valleys and the Chaco region. Risk factors for house infestation by T. infestans were identified, and an eco-health intervention based on education and community participation was carried out to reduce the risks of house infestation. It consisted of implementing simple and low cost vector control techniques such as coating of mud walls, cleaning activities and removal of poultry that enter rooms to lay eggs. The eco-health intervention significantly reduced the number of infested bedrooms, the mean abundance of T. infestans in bedrooms and beds, especially in the Chaco region. Mud wall coating was well accepted and could be proposed as a supplementary tool to the National Program of Chagas Disease Control to enhance the effects of insecticide sprayings. Even if cleaning activities were still neglected, community participation proved to be effective in reducing house infestation. © The author 2015.

    The effectiveness of rotavirus vaccine in the field may set the stage for a changing landscape of diarrheal illness affecting children worldwide. Norovirus and rotavirus are the two major viral enteropathogens of childhood. This study describes the prevalence of norovirus and rotavirus 2 years after widespread rotavirus vaccination in Cochabamba, Bolivia. Stool samples from hospitalized children with acute gastroenteritis (AGE) and outpatients aged 5-24 months without AGE were recruited from an urban hospital serving Bolivia's third largest city. Both viruses were genotyped, and norovirus GII.4 was further sequenced. Norovirus was found much more frequently than rotavirus. Norovirus was detected in 69/201 (34.3%) of specimens from children with AGE and 13/71 (18.3%) of those without diarrhea. Rotavirus was detected in 38/201 (18.9%) of diarrheal specimens and 3/71 (4.2%) of non-diarrheal specimens. Norovirus GII was identified in 97.8% of norovirus-positive samples; GII.4 was the most common genotype (71.4% of typed specimens). Rotavirus G3P[8] was the most prevalent rotavirus genotype (44.0% of typed specimens) and G2P[4] was second most prevalent (16.0% of typed specimens). This community is likely part of a trend toward norovirus predominance over rotavirus in children after widespread vaccination against rotavirus. © The American Society of Tropical Medicine and Hygiene.

La expropiación mexicana de 1938 alcanzó una dimensión trasnacional más allá de sus repercusiones diplomáticas: una experiencia percibida bajo muy diversos prismas en cada país latinoamericano. ¿Cómo fue vista la expropiación mexicana en los Andes bolivianos? Se argumenta que en la Paz, y en Sucre, diversos sectores de la sociedad leyeron esa expropiación tras los filtros del conflicto con la Standard Oil of Bolivia y del debate ideológico y político en torno a la recién creada YPFB, y cargaron de otro significado este episodio nacionalista al adaptarlo al contexto boliviano, dialogando simultáneamente con el sustrato previo de recepción de la revolución mexicana en la región, así como con el especial contexto político, económico y diplomático andino. Razones de orden nacional e internacional explican las reacciones ante el episodio petrolero mexicano en Bolivia, tanto como la percepción de estas por parte de la diplomacia mexicana.This article deals with a relevant subject in Latin American historiography, that being the Mexican oil expropriation during the Lázaro Cárdenas government and provides original information as well as an innovative approach that goes beyond strictly national historiographies, with the intention of contributing both to Bolivian and Mexican history.

    Full Text Available Venezuelan equine encephalitis virus (VEEV has been responsible for hundreds of thousands of human and equine cases of severe disease in the Americas. A passive surveillance study was conducted in Peru, Bolivia and Ecuador to determine the arboviral etiology of febrile illness. Patients with suspected viral-associated, acute, undifferentiated febrile illness of <7 days duration were enrolled in the study and blood samples were obtained from each patient and assayed by virus isolation. Demographic and clinical information from each patient was also obtained at the time of voluntary enrollment. In 2005-2007, cases of Venezuelan equine encephalitis (VEE were diagnosed for the first time in residents of Bolivia; the patients did not report traveling, suggesting endemic circulation of VEEV in Bolivia. In 2001 and 2003, VEE cases were also identified in Ecuador. Since 1993, VEEV has been continuously isolated from patients in Loreto, Peru, and more recently (2005, in Madre de Dios, Peru. We performed phylogenetic analyses with VEEV from Bolivia, Ecuador and Peru and compared their relationships to strains from other parts of South America. We found that VEEV subtype ID Panama/Peru genotype is the predominant one circulating in Peru. We also demonstrated that VEEV subtype ID strains circulating in Ecuador belong to the Colombia/Venezuela genotype and VEEV from Madre de Dios, Peru and Cochabamba, Bolivia belong to a new ID genotype. In summary, we identified a new major lineage of enzootic VEEV subtype ID, information that could aid in the understanding of the emergence and evolution of VEEV in South America.

    Tailings from mining activities in Bolivia represent an environmental problem. In the vicinity of the tin mines of Llallagua, Potosi department, there are large dumps and tailings. We present a study of the use of these wastes as raw materials for the manufacture of glass. This procedure aims to contribute to environmental remediation of mining areas through the vitrification, a process which offers an alternative for stabilization of hazardous waste. In addition, the marketing of the obtained product would provide an additional income to the mining areas. For this study three samples of mining waste, with grain size between sand and silt, were used. The chemical composition of these raw materials, determined by X-ray fluorescence, is granitic, with high contents of heavy metals. On the basis of its composition, glass were made from silica glass by adding CaCO{sub 3} and Na{sub 2}CO{sub 3}. The thermal cycle has been determined from TDA. Tg values of glass range from 626 degree centigrade to 709 degree centigrade. Leaching tests of the obtained glasses confirm their capacity to retain heavy metals. (Author) 38 refs.

De 1992 a 1996 se realizó un estudio seroepidemiológico con el fin de adquirir una primera visión de conjunto sobre las prevalencias de las infecciones por virus de la hepatitis B (VHB, C (VHC, D (VHD y E (VHE en distintas poblaciones de Bolivia. Sobre la base de los datos obtenidos en otros lugares de América Latina, se prestó atención especial al estudio de las comunidades autóctonas de la región amazónica. En las zonas rurales del altiplano andino, la infección por VHB presentó una prevalencia general que correspondería a una situación de endemia media o baja (11,2% y no se encontró ningún portador de anticuerpos contra VHC o VHD. En dos poblaciones de alto riesgo de la ciudad de Cochabamba (niños sin hogar y trabajadoras del sexo, la prevalencia de infección por VHB fue similar (11,6% y podría considerarse baja en comparación con la de otras poblaciones análogas de núcleos urbanos en América Latina. La correspondiente al VHC (un caso positivo, 0,5% sería parecida a la descrita en esas mismas poblaciones, si bien el escaso número de muestras estudiadas no permite extraer conclusiones más firmes. En concordancia con observaciones anteriores de comunidades similares de zonas tropicales de Suramérica, en las poblaciones autóctonas de la Amazonia boliviana la infección por VHB es sumamente endémica (prevalencia general de 74,0%, pero no se ha detectado la circulación de VHC. Se sabe que la transmisión de VHB es horizontal y tiene lugar desde edades muy tempranas, pero se desconocen los mecanismos de esa actividad. A los 10 años de edad, más de la mitad de la población ya ha experimentado la infección natural que, 10 años más tarde, se habrá difundido a prácticamente toda la población.

  7. From Conflict to Collaboration: An Innovative Approach to Reducing Coca Cultivation in Bolivia

    Full Text Available Upon his presidential election, Bolivian coca grower leader Evo Morales adopted a policy of promoting consensual coca reduction through social control, a sophisticated coca monitoring system, and economic development. That strategy is paying off. In 2011, coca cultivation decreased by 13 per cent according to the U.S. government. The Morales administration has also made significant progress facing the ongoing challenges of drug production and trafficking. Seizures of coca paste and cocaine and destruction of drug laboratories have steadily increased since President Morales took office. Despite continued tensions in bilateral relations, U.S.-Bolivian counter-drug cooperation continues and the signing of a new framework agreement in 2011 should lead to an exchange of ambassadors. Internationally, Bolivia has successfully gained acceptance of the right to the traditional use of coca within its own territory. But Bolivia’s efforts must be carried out in tandem with effective demand reduction strategies to shrink the global cocaine market.

    2008-08-01

    This study examines a broad array of theory-based factors derived from diffusion research that affect the current and intended use of solar water disinfection (SODIS), a simple, low-cost technology for treating drinking water at the household level. The perceived attributes of an innovation, the nature of the social system in which it is diffused, the extent of change agents' promotional efforts in diffusing it, and the nature of the communication channels used were operationalized by 16 variables. The aim of the study is to determine the influence of each factor and its predictive power. Eight areas in Bolivia were visited, and 644 families were interviewed on the basis of a structured questionnaire. Simultaneous multiple regression analysis showed that 9 of the 16 factors derived from diffusion research contributed significantly to predicting the current use of SODIS. The implications of the findings for customizing future SODIS diffusion activities are outlined.

    Full Text Available This article considers ‘kirchnerism’ and ‘evism’ to be popular identity movements which have attempted to provide answers to the open social dislocations since the crisis of December 2001 in Argentina, and the cycle of protests from 2000-2005 in Bolivia. The emergence of both of these identity constructions has involved at least three simultaneous processes. Firstly, the gradual incorporation of public decision-making on subjects and demands which were formerly ignored; secondly, political divisions within communities; and, finally, establishing a nation within the new institutional framework currently in force. As these processes developed, some points of approach and distancing between the case studies were noted.

    Data on the distribution and abundance of Lutzomyia spp. (Diptera: Psychodidae) in Bolivia is scarce. Sand flies from an area of Leishmania (Viannia) braziliensis endemicity in the Isiboro-Secure National Park in the Department of Cochabamba were captured and identified to species. In total, 945 sand flies (789 females and 156 males) belonging to 15 species were collected from the four collection points in two study villages in 2007. With 549 (58.1%) specimens, Lutzomyia shawi was the most abundant species, followed by Lutzomyia (Trichophoromyia) sp. (22.2%), Lutzomyia llanosmartinsi (8.3%), Lutzomyia antunesi (4.3%), and Lutzomyia olmeca (2.1%). Abundance and species composition varied between rainy and dry seasons, with 99.3% of all sand flies being collected outdoors. Because of species abundance and confirmed Leishmania infection in previous entomological collections, we believe Lu. shawi is the vector of L. (Viannia) braziliensis in Isiboro-Secure National Park.

    2018-03-01

    The objective of this article was to characterize how urbanization and indigenous identity shape nutrition attitudes and practices in El Alto, a rapidly urbanizing and predominantly indigenous (Aymara) community on Bolivia's Andean plateau. We took a qualitative ethnographic approach, interviewing health care providers ( n = 11) and conducting focus groups with mothers of young children ( n = 4 focus groups with 25 mothers total [age = 18-43 years, 60% Aymara]). Participants generally described their urban environment as being problematic for nutrition, a place where unhealthy "junk foods" and "chemicals" have supplanted healthy, "natural," "indigenous" foods from the countryside. Placing nutrition in El Alto within a broader context of cultural identity and a struggle to harmonize different lifestyles and worldviews, we propose how an intercultural framework for nutrition can harmonize Western scientific perspectives with rural and indigenous food culture.

    We studied the toxicity caused by chronic ingestion of Pteridium aquilinum (bracken) in cattle in the humid Chaco of Tarija, Bolivia. Bovine enzootic haematuria (BEH) and Carcinoma of the esophagus (CE) affected the herds. Sick animals showed caquexia, anemia, leucopenia and urine that turned from pink to intense red color with the presence of blood clots. Cattle grazed in the humid forests of the mountains where P aquilinum represented more than 50% of the plants. P aquilinum var arachnoideum and P aquilinum var Caudatum were present. Toxic norsesquiterpene, ptaquiloside, was identified in both varieties. Carcinomas were in the urinary bladders and esophagus of 100% and 50% of the cattle, respectively. Control of the intoxication could be difficult due to geographic characteristics of this Bolivian region.

    Full Text Available This study analyzes the current relationship between the extraction of lithium, communitarian conflict and development policies in Argentina and Brazil and compares what is happening in one country with what is happening in the other. It is based on the premise that the interaction of the technology-industry-politics triangle is key to an understanding of the modes of development in our peripheral region. The main hypothesis is that an extractive logic predominates in Argentina, while there is a different approach to lithium in Bolivia, due to a wager on a stronger linkage between national actors and the endogenous growth of a productive network, although the results are still uncertain. The study draws on secondary sources, first-hand documentation and interviews in both countries.

    Allele frequencies and forensic parameters for 15 autosomal loci included in the AmpFlSTR® Identifiler kit were estimated in a sample of 57 unrelated Afro-descendants from Nor Yungas (Bolivia). Buccal swabs samples were obtained from voluntary donors, after consent was given. All loci were in Hardy-Weinberg equilibrium after Bonferroni correction. D21S11 was the most informative locus, while the least discriminating locus was D3S1358. The combined power of discrimination and the combined probability of exclusion were >0.99999999 and >0.99997, respectively. The multidimensional scaling (MDS) plot generated by Rst matrix supported that Afro-Bolivians of Nor Yungas preserved a stronger African descent compared to other admixed Latin American populations. These results amplified the Bolivian databases of autosomal STR loci and may provide a useful tool for human identification tests and population genetic studies.

  16. From Lemongrass to Ivermectin: Ethnomedical Management of Chagas Disease in Tropical Bolivia.

    Forsyth, Colin

    2017-07-31

    Chagas disease is a neglected tropical disease; the only viable drugs are outdated and produce frequent side effects, and the overwhelming majority of cases are undiagnosed and untreated. Globally, people encounter numerous impediments to accessing biomedical treatment for Chagas disease. However, little is known about how people with Chagas disease manage their health outside the biomedical system. In this article, I discuss knowledge of ethnomedical treatments among marginalized patients in an endemic area of Bolivia. I interviewed 68 patients, 63 (93 percent) of whom had positive diagnoses for Chagas disease. Participants free listed 66 ethnomedical remedies either for Chagas disease (n = 39) or its cardiac symptoms. Participants stressed the accessibility of ethnomedical remedies in contrast to the multiple barriers to accessing biomedical treatment. Far from eroding in the face of globalization and sociopolitical marginalization, ethnomedical knowledge in the study area is dynamic and flexible, communicated through various channels.

  17. Blaming Machismo: How the Social Imaginary is Failing Men with HIV in Santa Cruz, Bolivia.

    2017-01-01

    Drawing from an ethnography of HIV care in Santa Cruz, Bolivia, in this article I explore how the social imaginary surrounding gender relations shapes men's experiences of seeking care for and living with HIV. Popular understandings of gender relations, which draw heavily on the machismo concept, intersect with a global health master narrative that frames women as victims in the AIDS epidemic in a way that generates a strong sentiment of blaming machismo within local HIV/AIDS-related services. Statements such as, "it's because of machismo" are used to explain away epidemiological trends. Participant observation in the context of HIV care, coupled with illness narrative interviews, illuminate how blaming machismo shapes men's experiences of care and the ways that they feel excluded from various forms of support. Thus, the illness experiences of men with HIV problematize the machismo concept and how it is drawn upon in the context of care.

    Secretions from the dorsal gland of male and female free-ranging adult white-lipped peccaries (Tayassu pecari) from Bolivia were analyzed by gas chromatography-mass spectrometry. Fifty compounds were identified, some provisionally. Secretions of both sexes contain saturated and unsaturated C5-C18 carboxylic acids as well as isomers of the diterpene springene. The females' secretions uniquely possess farnesyl esters of C8 and C10 carboxylic acids, whereas the males' secretions uniquely showed two compounds provisionally identified as monounsaturated C16 lactones. Saturated high-molecular-weight esters of C10 carboxylic acids are more abundant in the females' secretions than in those of the males. The secretions of both sexes also contain monoalkanoate esters of methylhydroquinone as major components.

    Full Text Available Trypanosoma cruzi infection was studied in 1,298 sera samples of blood banks from 7 capital departments of Bolivia, using the immunofluorescence test (IFI and Enzyme Linked Immunosorbent Assay (Elisa. The percentages of positivity in these 7 departments have an average of 28% and are distributed as follows: Sta. Cruz 51%, Tarija 45%, Cochabamba 28%, Sucre 39%, La Paz 4.9%, Oruro 6% and Potosi 24%. The prevalence is related with the altitude levels of the different departments. However in Potosi (3,945 m we found a 24% of prevalence, probably due to the proximity of endemic valleys to the city. The authors suggest a strict control in blood donors since there exists a great risk of infection

    Dengue fever was first recognized in Bolivia in 1931. However, very limited information was available to date regarding the genetic characterization and epidemiology of Bolivian dengue virus strains. Here, we performed genetic characterization of the full-length envelope gene of 64 Bolivian isolates from 1998 to 2008 and investigated their origin and evolution to determine whether strains circulated simultaneously or alternatively, and whether or not multiple introductions of distinct viral variants had occurred during the period studied. We determined that, during the last decade, closely related viruses circulated during several consecutive years (5, 6, and 6 years for DENV-1, DENV-2, and DENV-3, respectively) and the co-circulation of two or even three serotypes was observed. Emergence of new variants (distinct from those identified during the previous episodes) was identified in the case of DENV-1 (2007 outbreak) and DENV-2 (2001 outbreak). In all cases, it is likely that the viruses originated from neighboring countries. PMID:19505253

    To better describe the genetic diversity of hantaviruses associated with human illness in South America, we screened blood samples from febrile patients in Chapare Province in central Bolivia during 2008–2009 for recent hantavirus infection. Hantavirus RNA was detected in 3 patients, including 1 who died. Partial RNA sequences of small and medium segments from the 3 patients were most closely related to Andes virus lineages but distinct (1 hantaviruses; the highest prevalence was among agricultural workers. Because of the high level of human exposure to hantavirus strains and the severity of resulting disease, additional studies are warranted to determine the reservoirs, ecologic range, and public health effect of this novel strain of hantavirus.

    Full Text Available Insect macroecology and conservation biogeography studies are disproportionately scarce, especially in the Neotropics. Dung beetles are an ideal focal taxon for biodiversity research and conservation. Using distribution and body size data on the ecologically important Phanaeini, the best-known Neotropical dung beetle tribe, we determined elevational patterns of species richness, endemism, body size, and elevational range in Bolivia, specifically testing Bergmann's and Rapoport's rule. Richness of all 39 species and of 15 ecoregional endemics showed a hump-shaped pattern peaking at 400 m, but overall declined strongly with elevation up to 4000 m. The relationship between endemic and total species richness appeared to be curvilinear, providing only partial support for the null hypothesis that species-rich areas are more likely to be centers of endemism by chance alone. An elevational increase in the proportion of ecoregional endemics suggests that deterministic factors also appear to influence endemism in the Andes. When controlling for the effect of area using different species-area relationships, the statistically significant richness peak became more pronounced and shifted upslope to 750 m. Larger species did not have higher elevational mid-points, and mean body size decreased significantly with elevation, contradicting Bergmann's rule. Rapoport's rule was supported: species with higher elevational mid-points had broader elevational ranges, and mean elevational range increased significantly with elevation. The elevational decrease of phanaeine richness is in accordance with studies that demonstrated the combined influence of temperature and water availability on species diversity, but also is consistent with niche conservatism. For invertebrates, confirmation of Rapoport's and refutation of Bergmann's rule appear to be scale-invariant general patterns.

    Agricultural science can address a population's vitamin, amino acid and mineral malnutrition through biofortification - agronomy, plant breeding and biotechnology to develop crops with high nutrient contents. Biofortified crop varieties should be grown in areas with populations at risk of nutrient deficiency and in areas where the same crop is already grown and consumed. Information on the population at risk of nutrient deficiency is rarely available for sub-national administrative units, such as provinces, districts, and municipalities. Nor is this type of information commonly analyzed with data on agricultural production. This project developed a method to identify populations at risk of nutrient deficiency in zones with high crop production, places where biofortification interventions could be targeted. Nutrient deficiency risk data were combined with crop production and socioeconomic data to assess the suitability of establishing an intervention. Our analysis developed maps of candidate sites for biofortification interventions for nine countries in Latin America and the Caribbean. Results for Colombia, Nicaragua, and Bolivia are presented in this paper. Interventions in northern Colombia appear promising for all crops, while sites for bean biofortification are widely scattered throughout the country. The most promising sites in Nicaragua are found in the center-north region. Candidate sites for biofortification in Bolivia are found in the central part of the country, in the Andes Mountains. The availability and resolution of data limits the analysis. Some areas show opportunities for biofortification of several crops, taking advantage of their spatial coincidence. Results from this analysis should be confirmed by experts or through field visits. This study demonstrates a method for identifying candidate sites for biofortification interventions. The method evaluates populations at risk of nutrient deficiencies for sub-national administrative regions, and

    Bolivia's forests contribute to the global carbon and water cycle, as well as to global biodiversity. The survival of these forests may be at risk due to climate change. To explore the associated mechanisms and uncertainties, a regionally adapted dynamic vegetation model (LPJ-GUESS) was implemented for the Bolivian case, and forced with two contrasting CMIP5 RCP8.5 climate change projections. The CNRM-CM5 projects an rainfall increase of about 5% in lowland Bolivia, while IPSL-CM5A-LR projects a decrease of about 17-26%. Changes in carbon stocks and fluxes were evaluated, factoring out the individual contributions of atmospheric carbon dioxide ([CO2]), temperature and precipitation. Special attention was paid to the effect of rising temperatures on photosynthesis, respiration, and the atmospheric demand for transpiration. Impacts ranged from a strong increment to a severe loss of vegetation carbon (Cv), depending on differences in climate projections, as well as the physiological response to rising [CO2], see figure. The simulated loss Cv was primarily driven by a reduction in gross primary productivity, and secondarily by enhanced emissions from fires and autotrophic respiration. In the wet forest, less precipitation and higher temperatures equally reduced Cv, while in the dry forest, the impact of precipitation was dominating. The temperature-related reduction of Cv was mainly due to a decrease in photosynthesis, and only to lesser extent because of more autotrophic respiration and less stomatal conductance as a response to an increasing atmospheric demand. Tropical dry forests were simulated to virtually disappear, regardless of the fertilizing effect of rising [CO2], suggesting a higher risk for dry forest loss along the drier southern fringe of the Amazon. Implications for climate change adaptation and mitigation measures are discussed.

    This study seeks to develop an understanding that can guide development of programs to improve health and care for individuals with Non-Communicable Diseases (NCDs) in La Paz, Bolivia, where NCDs are prevalent and primary care systems are weak. This exploratory investigation examines the characteristics of chronic disease patients in the region, key health related behaviors, and their perceptions of the care that they receive. The longer-term goal is to lay groundwork for interventional studies based on the principles of the Chronic Care Model (CCM). The study is based on two surveys of adults (> 18 years old) administered in 2014 in La Paz, Bolivia. A total of 1165 adult patients participated in the first screening survey. A post-screening second survey, administered only on those who qualified based on Survey 1, collected more detailed information about the subjects' general health and health related personal circumstances, several health behaviors, health literacy, and their perceptions of care received. A final data set of 651 merged records were used for analysis. Characteristic of a low-income country, the majority of participants had low levels of education, income, health literacy and high rates of under/unemployment. Nearly 50% of participants reported 2 or more NCDs. Seventy-four percent (74%) of respondents reported low levels of medication adherence and 26% of the population was found to have an undiagnosed depressive disorder. Overall, the perception of care quality was low (60%), particularly in those under the age of 45. Significant relationships emerged between several sociodemographic characteristics, health behaviors, and perceptions that have major implications for improving NCD care in this population. These findings illustrate some of the challenges facing low-income countries where reversing the tide of NCDs is of great importance. The prevalence of NCDs coupled with challenging social determinants of health, poor medication adherence, low

    While health policies are a major focus in disciplines such as public health and public policy, there is a dearth of work on the histories, social contexts, and personalities behind the development of these policies. This article takes an anthropological approach to the study of a health policy's origins, based on ethnographic research conducted in Bolivia between 2010 and 2012. Bolivia began a process of health care reform in 2006, following the election of Evo Morales Ayma, the country's first indigenous president, and leader of the Movement Toward Socialism (Movimiento al Socialism). Brought into power through the momentum of indigenous social movements, the MAS government platform addressed racism, colonialism, and human rights in a number of major reforms, with a focus on cultural identity and indigeneity. One of the MAS's projects was the design of a new national health policy in 2008 called The Family Community Intercultural Health Policy (Salud Familiar Comunitaria Intercultural). This policy aimed to address major health inequities through primary care in a country that is over 60% indigenous. Methods used were interviews with Bolivian policymakers and other stakeholders, participant observation at health policy conferences and in rural community health programs that served as models for aspects of the policy, and document analysis to identify core premises and ideological areas. I argue that health policies are historical both in their relationship to national contexts and events on a timeline, but also because of the ways they intertwine with participants' personal histories, theoretical frameworks, and reflections on national historical events. By studying the Bolivian policymaking process, and particularly those who helped design the policy, it is possible to understand how and why particular progressive ideas were able to translate into policy. More broadly, this work also suggests how a uniquely anthropological approach to the study of health policy

    Background For Chagas disease, the most serious infectious disease in the Americas, effective disease control depends on elimination of vectors through spraying with insecticides. Molecular genetic research can help vector control programs by identifying and characterizing vector populations and then developing effective intervention strategies. Methods and Findings The population genetic structure of Triatoma infestans (Hemiptera: Reduviidae), the main vector of Chagas disease in Bolivia, was investigated using a hierarchical sampling strategy. A total of 230 adults and nymphs from 23 localities throughout the department of Chuquisaca in Southern Bolivia were analyzed at ten microsatellite loci. Population structure, estimated using analysis of molecular variance (AMOVA) to estimate FST (infinite alleles model) and RST (stepwise mutation model), was significant between western and eastern regions within Chuquisaca and between insects collected in domestic and peri-domestic habitats. Genetic differentiation at three different hierarchical geographic levels was significant, even in the case of adjacent households within a single locality (R ST = 0.14, F ST = 0.07). On the largest geographic scale, among five communities up to 100 km apart, R ST = 0.12 and F ST = 0.06. Cluster analysis combined with assignment tests identified five clusters within the five communities. Conclusions Some houses are colonized by insects from several genetic clusters after spraying, whereas other households are colonized predominately by insects from a single cluster. Significant population structure, measured by both R ST and F ST, supports the hypothesis of poor dispersal ability and/or reduced migration of T. infestans. The high degree of genetic structure at small geographic scales, inferences from cluster analysis and assignment tests, and demographic data suggest reinfesting vectors are coming from nearby and from recrudescence (hatching of eggs that were laid

    This study compares findings from research projects involving different genetic, environmental, and cultural contexts: a study of lifestyle and health from American Samoa (ASLS) and the Bolivian project. Reproduction and Ecology in Provincia Aroma (REPA). This paper presents analyses of varying economic strategies and their association with nutritional status indicators in each population. The ASLS sample includes 66 Samoan women and the REPA sample includes 210 Aymara women. Principle components analysis of household economic resources within each sample extracted two significant factors: one represents modernizing influences including education and occupational status, and the other represents ethnographically salient traditional economic behavior. The traditional pattern includes adding household members in Samoa and selling agricultural products in Bolivia. This analysis places each woman along two continua, traditional and modern, based on her household mobilization of economic resources, permitting an understanding of the patterns underlying household economic behavior that is not possible in univariate analyses of socioeconomic variables. For the Bolivian women the strategy involving more education and higher occupational status was associated with higher measures of several nutritional status indicators, including body mass index, arm muscle area, and peripheral skinfolds. But among the Samoan women, where substantial obesity was the norm, there were no significant differences in anthropometric measurements based on economic strategies. These data argue for the importance of directly measuring the potential consequences of variation in household economic strategies rather than merely inferring such, and of assessing ethnographically relevant aspects of household economic production rather than limiting analyses to non-context-specific economic indicators such as income. This focus on household strategy is likely to be fruitful especially where economic and

Ambas especies son asignables al grupo peruanus y se diferencian de las otras cuatro especies que existen en el país por presentar el primer dedo más corto que el segundo, tener membrana basal y por sus colores y diseños dorsales y ventrales. La musculatura ha sido pocas veces descrita para especies de Phrynopus. Phrynopus adenopleurus, especie nueva, posee una inusual musculatura mandibular y del muslo, muy poco parecida a lo descrito para otras especies del género.We describe two new species of Phrynopus from cloud forests in Cochabamba, Bolivia. The new species are assigned to the P. peruanus group and are characterized by the presence of basal webbing, distinctive coloration, and by having the first finger shorter than the second. The first of these new species was collected near Montepunko in Parque Nacional Carrasco and is known from eight males and six females. Among its distinctive characteristics are round cream-colored glands on its flanks. A second species is known from one male and one female collected near "Zona de Aguirre" near the northwest border of the park. V and X-shaped blotches and a dorsum that is smooth except for dorsolateral and scapular folds characterize this species. Musculature has rarely been described for species of Phrynopus. The species from Montepunko has unusual gular and thigh musculature that is quite unlike other species of the genus.

    Full Text Available Abstract Background Molecular epidemiological studies of HIV-1 in South America have revealed the occurrence of subtypes B, F1 and BF1 recombinants. Even so, little information concerning the HIV-1 molecular epidemiology in Bolivia is available. In this study we performed phylogenetic analyses from samples collected in Bolivia at two different points in time over a 10 year span. We analyzed these samples to estimate the trends in the HIV subtype and recombinant forms over time. Materials and methods Fifty one HIV-1 positive samples were collected in Bolivia over two distinct periods (1996 and 2005. These samples were genetically characterized based on partial pol protease/reverse transcriptase (pr/rt and env regions. Alignment and neighbor-joining (NJ phylogenetic analyses were established from partial env (n = 37 and all pol sequences using Mega 4. The remaining 14 env sequences from 1996 were previously characterized based on HMA-env (Heteroduplex mobility assay. The Simplot v.3.5.1 program was used to verify intragenic recombination, and SplitsTree 4.0 was employed to confirm the phylogenetic relationship of the BF1 recombinant samples. Results Phylogenetic analysis of both env and pol regions confirmed the predominance of "pure" subtype B (72.5% samples circulating in Bolivia and revealed a high prevalence of BF1 genotypes (27.5%. Eleven out of 14 BF1 recombinants displayed a mosaic structure identical or similar to that described for the CRF12_BF variant, one sample was classified as CRF17_BF, and two others were F1pol/Benv. No "pure" HIV-1 subtype F1 or B" variant of subtype B was detected in the present study. Of note, samples characterized as CRF12_BF-related were depicted only in 2005. Conclusion HIV-1 genetic diversity in Bolivia is mostly driven by subtype B followed by BF1 recombinant strains from the CRF12_BF "family". No significant temporal changes were detected between the mid-1990s and the mid-2000s for subtype B (76.2% vs 70

    Full Text Available El presente estudio tuvo por objetivo evaluar la calidad de los servicios de anticoncepción en la ciudad de El Alto, Bolivia. En su diseño se han contemplado cuatro elementos: 1 las relaciones entre los proveedores de servicios y sus clientes, 2 la disponibilidad de métodos anticonceptivos, 3 las condiciones de los servicios, y 4 la satisfacción de las usuarias. También se han tenido en cuenta las opiniones de los proveedores y de las usuarias y no usuarias de estos servicios, quienes se clasificaron como gubernamentales o no gubernamentales, de acuerdo con la administración de la institución a la que pertenecían. Los datos provinieron de un análisis de la situación de dichos servicios y de testimonios obtenidos de las participantes durante 1995. En cuanto a las relaciones interpersonales, se encontró que los proveedores percibían el trato del médico más favorablemente que las clientas, en tanto que las no usuarias lo percibían desfavorablemente. La percepción de un trato igualitario se correlacionó positivamente con la vestimenta que usaban las clientas. En cuanto a la disponibilidad de los métodos anticonceptivos, 15 de las 36 instituciones encuestadas no disponían de métodos modernos, a pesar de la existencia de una política nacional para proveerlos a la población. La oferta de estos servicios a parejas y a adolescentes es escasa, principalmente en las instituciones gubernamentales. El análisis de las condiciones de los servicios demostró que en algunas instituciones había problemas graves en la provisión de una atención de mínima calidad. Finalmente, este trabajo describe cómo la mayoría de estas limitaciones en la prestación de servicios de anticoncepción en El Alto pueden subsanarse mediante estrategias de costo moderado.The objective of this study was to evaluate the quality of contraception services in the city of El Alto, Bolivia.

    The Bolivia-Brazil Natural Gas Pipeline starts at Santa Cruz de La Sierra city, in Bolivia, and goes until Canoas City (RS) in Brazil, with a total extent of 3,150 km. The pipeline crosses in the 2,593 km established in Brazilian soil, the most diverse types of geology and geomorphology. Along the line, the right-of-way (ROW) also crosses a lot of roads, railways, rivers and lakes. During a routine inspection (foot patrol), signs of instability were detected at an embankment slope of a highway of the Santa Catarina state, at the pipeline crossing. An eventual failure of this slope could put the pipeline at risk. The aim of this paper is to present the aspects of the stabilizations phases, since field investigation, design, works, instrumentation, until monitoring. Emphasis is given to the design criteria to pipeline safety. The solution adopted is composite by soil nailing, a changing of slope inclination and superficial drainage system. (author)

    Full Text Available Bolivia is a high-endemic country for Chagas disease, for which the principal vector is Triatoma infestans (Triatominae. This is a mainly domestic species that is also found in the wild environment. Recently, an increasing number of studies have shown the importance of Triatominae resistance to insecticides, especially in Bolivia. Data regarding the susceptibility/resistance of wild and domestic populations of T. infestans to deltamethrin are presented. For the first time, domestic populations of the department of Santa Cruz were tested, showing low resistance. Although most of the wild populations were found to be susceptible to deltamethrin, three populations from three departments showed a mortality rate of less than 100%. This result is emphasised here.

    Full Text Available Is it possible to justify resource extractivism to provide progressive welfare politics and still respect the constitutional rights of nature? The Indigenous concept of Sumak Kawsay on human beings living in harmony with each other and the environment is the fundamental framing of the new constitutions of Ecuador and Bolivia. These constitutional reforms embrace strengthened proper rights of nature and similarly of ethnic rights. However, the same constitutions grant the State the right to exploit and commercialize natural resources and extractivism has increased. This study revises the tensions between welfare politics, extractivism and the rights of nature and the Indigenous peoples in the new constitutional settings of Bolivia and, particularly, Ecuador. The article argues that Sumak Kawsay challenges dominating understandings of the concepts of welfare, common good and development, and likewise that a pragmatic approach is applied by national governments towards the constitutional rights of nature amidst other human values.

    Chilean red chili peppers contaminated with aflatoxins were reported in a previous study. If the development of gallbladder cancer (GBC) in Chile is associated with a high level of consumption of aflatoxin-contaminated red chili peppers, such peppers from other countries having a high GBC incidence rate may also be contaminated with aflatoxins. We aimed to determine whether this might be the case for red chili peppers from Bolivia and Peru. A total of 7 samples (3 from Bolivia, 4 from Peru) and 3 controls (2 from China, 1 from Japan) were evaluated. Aflatoxins were extracted with acetonitrile:water (9:1, v/v) and eluted through an immuno-affinity column. The concentrations of aflatoxins B1, B2, G1, and G2 were measured using high-performance liquid chromatography (HPLC), and then the detected aflatoxins were identified using HPLC-mass spectrometry. In some but not all of the samples from Bolivia and Peru, aflatoxin B1 or aflatoxins B1 and B2 were detected. In particular, aflatoxin B1 or total aflatoxin concentrations in a Bolivian samples were above the maximum levels for aflatoxins in spices proposed by the European Commission. Red chili peppers from Bolivia and Peru consumed by populations having high GBC incidence rates would appear to be contaminated with aflatoxins. These data suggest the possibility that a high level of consumption of aflatoxin-contaminated red chili peppers is related to the development of GBC, and the association between the two should be confirmed by a case-control study.

    Our previous study detected aflatoxins in red chili peppers from Chile, Bolivia, and Peru, each of which have a high incidence of gallbladder cancer (GBC). Since the aflatoxin B1 concentration was not so high in these peppers, it is important to clarify the presence of other mycotoxins. Here we attempted to determine any associations between the concentrations of aflatoxins and ochratoxin A (OTA) in red chili peppers, and the corresponding GBC incidences. We collected red chili peppers from three areas in Peru: Trujillo (a high GBC incidence area), Cusco (an intermediate GBC incidence area), and Lima (a low GBC incidence rate), and from Chile and Bolivia. Aflatoxins and OTA were extracted with organic solvents. The concentrations of aflatoxins B1, B2, G1, and G2, and OTA were measured by high-performance liquid chromatography. The values obtained were compared with the incidence of GBC in each area or country. All of the red chili peppers from the three areas showed contamination with aflatoxins below the Commission of the European Communities (EC) recommended limits (5 μg/kg), but the OTA contamination of two samples was above the EC recommended limit (15 μg/kg). The mean concentrations of OTA in the peppers from Chile (mean 355 μg/kg, range Bolivia (mean 207 μg/kg, range 0.8-628 μg/kg), which has a high incidence of GBC, were higher than that in Peru (14 μg/kg, range Bolivia, and Peru was stronger than that of aflatoxins. Our data suggest that OTA in red chili peppers may be associated with the development of GBC.

    Venezuelan equine encephalitis virus (VEEV) has been responsible for hundreds of thousands of human and equine cases of severe disease in the Americas. A passive surveillance study was conducted in Peru, Bolivia and Ecuador to determine the arboviral etiology of febrile illness. Patients with suspected viral-associated, acute, undifferentiated febrile illness of Peru, and more recently (2005), in Madre de Dios, Peru. We performed phylogenetic analyses with VEEV from Bolivia, Ecuador and Peru and compared their relationships to strains from other parts of South America. We found that VEEV subtype ID Panama/Peru genotype is the predominant one circulating in Peru. We also demonstrated that VEEV subtype ID strains circulating in Ecuador belong to the Colombia/Venezuela genotype and VEEV from Madre de Dios, Peru and Cochabamba, Bolivia belong to a new ID genotype. In summary, we identified a new major lineage of enzootic VEEV subtype ID, information that could aid in the understanding of the emergence and evolution of VEEV in South America.

    To investigate the prevalence of methicillin-resistant Staphylococcus aureus (MRSA) nasal carriage in rural and urban community settings of Bolivia and Peru. MRSA nasal carriage was investigated in 585 individuals living in rural and urban areas of Bolivia and Peru (one urban area, one small rural village, and two native communities, one of which was highly isolated). MRSA isolates were subjected to molecular analysis for the detection of virulence genes, characterization of the staphylococcal cassette chromosome mec (SCCmec), and genotyping (multilocus sequence typing (MLST) and pulsed-field gel electrophoresis (PFGE)). An overall very low prevalence of MRSA nasal carriage was observed (0.5%), with MRSA carriers being detected only in a small rural village of the Bolivian Chaco. The three MRSA isolates showed the characteristics of community-associated MRSA (being susceptible to all non-beta-lactam antibiotics and harboring the SCCmec type IV), were clonally related, and belonged to ST1649. This study provides an insight into the epidemiology of MRSA in community settings of Bolivia and Peru. Reliable, time-saving, and low-cost methods should be implemented to encourage continued surveillance of MRSA dissemination in resource-limited countries.

    The northern Altiplano plateau of southern Peru and northern Bolivia is one of the highest topographic features on the Earth, flanked by Western and Eastern Cordillera along its margin. It has strongly influenced the local and far field lithospheric deformation since the early Miocene (Masek et al., 1994). Previous studies have emphasized the importance of both the crust and upper mantle in the evolution of Altiplano plateau (McQuarrie et al., 2005). Early tomographic and receiver function studies, south of 16° S, show significant variations in the crust and upper mantle properties in both perpendicular and along strike direction of the Altiplano plateau (Dorbath et. al., 1993; Myers et al., 1998; Beck and Zandt, 2002). In order to investigate the nature of subsurface lithospheric structure below the northern Altiplano, between 15-18° S, we have determined three-dimensional seismic tomography models for Vp and Vs using P and S-wave travel time data from two recently deployed local seismic networks of CAUGHT and PULSE. We also used data from 8 stations from the PERUSE network (PERU Subduction Experiment). Our preliminary tomographic models show a complex variation in the upper mantle velocity structure with depth, northwest and southeast of lake Titicaca. We see the following trend, at ~85 km depth, northwest of lake Titicaca: low Vp and Vs beneath the Western Cordillera, high Vs beneath the Altiplano and low Vp and Vs beneath the Eastern Cordillera. This low velocity anomaly, beneath Eastern Cordillera, seems to coincide with Kimsachata, a Holocene volcano in southern Peru. At depth greater than ~85 km: we find high velocity anomaly beneath the Western Cordillera and low Vs beneath the Altiplano. This high velocity anomaly, beneath Western Cordillera, coincides with the well-located Wadati-Benioff zone seismicity and perhaps represents the subducting Nazca slab. On the southeast of lake Titicaca, in northern Bolivia, we see a consistently high velocity anomaly

    This case study analyses current migration dynamics in two regions of Bolivia: Northern Potosi, one of the main areas of outmigration in Bolivia, and the municipality of San Julian in the Department of Santa Cruz, a major destination for internal migrants, some of whom come from Northern Potosi. The research was qualitative in nature, with specific attention to breadth and accuracy in the information and analysis. The methods used were participative and the research was done in collaboration with the rural and indigenous organisations in the two selected areas: the Federation of Indigenous Ayllus of Northern Potosi (Federacion de Ayllus Originarios Indigenas del Norte de Potosi Charka Qhara Qhara - FAOI-NP) and the Federation of Intercultural Communities of San Julian (Federacion de Comunidades Interculturales de San Julian). The information gathering process examined a wide range of factors that may trigger migration, including the possible influence of climate change and public policies on migration. The key challenge was to understand current patterns of migration, the processes involved and the social, cultural, economic and political causes and effects, taking into account issues that are increasing in importance, such as climate change, and seeking to discover the extent of their influence in the midst of other factors that drive migration. It is well known that migration is not a simple occurrence. In fact, it involves a series of processes, motivations, causes and decisions. Because it is a collective rather than an individual process, it takes on the character of a 'social phenomenon' that is historically and geographically determined. In many cases, there are cultural practices of transhumance, such as agriculture on different ecological levels or the use of winter and summer pastures. This involves people moving from one place to another, sometimes travelling long distances and crossing districts for several months at a time. These transhumance

Se aplica el concepto de frontera de F. J.

Entones Brasil se acercó a Chile, y afrontaron juntos los problemas del Acre y de Antofagasta, que derivaron en las redacciones de los tratados de Petrópolis (1903 y de Paz y Amistad (1904. El artículo postula que Bolivia procedió de esta forma para impedir el avance brasileño, peruano y paraguayo sobre sus fronteras, y que la búsqueda del paraguas estadounidense fue una idea que Bolivia gestó para compensar el desequilibrio de poder.This work considers the Acre War as part of a multilateral context where the equilibrium of power was important in the reasoning behind the establishment of foreign relations. It uses the frontier concept developed by F. J. Turner to explain why their open frontier put Brazil and Bolivia in confrontation. This happened because of the Bolivian strategy of granting land to investors from the United States, Great Britain and France, which was interpreted by Brazil as an imperialist action promoted by the United States. This explains why Brazil established a cióse relationship with Chile to confront together their problems in Acre and Antofagasta, which led to the drafting of the Petrópilis (1903 and Paz y Amistad (1904 treaties. The article argues that Bolivia proceeded this way to avoid a Brazilian, Peruvian or Paraguayan territorial advance, seeking the support of the United States to compénsate the imbalance of power.

    Anopheles (Anopheles) pseudopunctipennis is a recognized malaria vector in the slopes of the Andes of Bolivia. There, other species might be involved in malaria transmission and one candidate could be Anopheles argyritarsis. Although it is generally admitted that this species is not a malaria vector in the neotropical region, its potential role in transmission is still controversial and this situation has to be cleared, at least for Bolivia. Comparing the vectorial efficiency of An. pseudopunctipennis with that of An. argyritarsis could solve the question. The two species were sampled throughout Bolivia to estimate their degree of co-existence in their distribution range. Vectorial efficiencies of the two species were compared in two ecologically different localities where the species were sympatric by analysing their vectorial capacities and components (i e, human biting rates, human biting index, survival, durations of the gonotrophic cycle and extrinsic cycle), and the entomological inoculation rates (EIR). Mosquitoes were sampled monthly during more than one year in the two localities. A monthly sample consisted in hourly captures in four houses (inside and outside) in each locality, during four consecutive nights. Climatic variables (temperature, humidity, potential evapo-transpiration and precipitations) were recorded to better understand variability in the entomological parameters. Relationships were analysed using multivariate methods. Anopheles pseudopunctipennis and An. argyritarsis are "altitude" species, sharing the same geographical distribution range in the Andes of Bolivia. No Plasmodium parasite was identified in An. argyritarsis and estimates of the vectorial capacity indicated that it is not a malaria vector in the two studied localities, unlike An. pseudopunctipennis which showed positive EIRs. This latter species, although not a very good malaria vector, exhibited better life traits values and better behavioural characteristics in favour of

Para proyectarse en el mundo globalizado es necesario interactuar desde la definición de los intereses "propios". Hay que definir los cambios en los paradigmas de la subjetividad para asumir la comparación y examinar las aptitudes para conservar y modificar a la nación. En suma, ¿Estamos construyendo formas específicas de ser en la globalización? La forma de entendernos en los "poderes" de la globalización es disponer de un arsenal mínimo de "saberes". Es una medición de la autonomía para relacionarse. Permite "negociar" la inserción en la globalización, que plantea las formas de una construcción conjunta y conflictiva de los sentidos de la historicidad (compromisos. Acerca de las tareas pendientes, en el ámbito político, el artículo sostiene que deben fortalecerse las instituciones: cuando la sociedad asedia con su dinámica contradictoria, las instituciones no pueden construir su lógica valórica. En el ámbito económico, debe re-enrumbarse el sentido de la competitividad: ¿Se puede conducir la eficiencia hacia la solidaridad? En el ámbito social, debe superarse la extrema pobreza: existe una enorme incapacidad para producir un pacto nacional contra la pobreza ya que los pactos políticos no tienen pactos sociales de sustento.La educación aparece como la posibilidad de (re conocer a la inserción internacional como una oportunidad.

    Bolivia is one of the poorest countries in Latin America. Health indicators are very poor, communicable diseases are prevalent and, coupled with malnutrition, remain the major killers of children under 5 years old. The Integrated Primary Health Care Project (PROISS) was a US$39 million project executed by the Ministry of Health (MOH), 50% financed by the World Bank and aimed at improving primary health care in the four largest Bolivian municipalities. The implementation of the project started in 1990 and ended in 1997. During implementation it went through three distinct phases: Phase 1 (1990-94) was a period characterized by conflict and confusion; Phase 2 (1995-mid-1996) documented major improvements in coverage and service quality; and Phase 3 (mid-1996-97) witnessed the decline of the project. This paper explores the factors that contributed to the success and the decline of the project, draws lessons for project managers and international agencies involved in the definition and implementation of social sector projects, and discusses the unlikelihood that externally financed projects can have a sustainable impact on the development of the health sector of recipient countries.

    To understand the cultural dimensions of HIV/AIDS among adolescent students. A cognitive anthropological study was undertaken in Cochabamba (Bolivia), Talca (Chile) and Guadalajara (Mexico), during 2007 and 2008. A total of 184 teenagers (from 14 to 19 years old) were selected by purposeful sampling at secondary schools in each country. Free association lists and pile sorts were utilized. Terms associated with the concept of HIV/AIDS and groups of conceptual dimensions were investigated. Subsequently, consensus analysis was performed using factorial principal components and dimensional analysis through hierarchical clusters and multidimensional scales. The differences between the country contexts were in the degree of consensus in relation to the term HIV/AIDS, which was greater in Cochabamba. In Talca and Guadalajara the youths mentioned metaphors of fighting against HIV/AIDS, while in Cochabamba participants talked about help, support and love that infected people should receive. The similarities among conceptions by youth from the three countries were: the risk factors (unprotected sexual practice and contact with specific population groups), the consequences (physical and social death, being the latter understood as social rejection of people living with HIV/AIDS) and the prevention of illness (based on information and condom use). For adolescent students, HIV/AIDS is a disease caused by sexual practices and drug use and involves harm, pain and death. HIV/AIDS prevention programs for adolescents should promote science based information on the topic and not concentrate only on the emotional and social consequences of HIV/AIDS.

    2013-11-01

    Full Text Available This article argues that relations between social movements and organizations and the State are not only developed based on defended objectives and interests in political negotiations, but are also developed within particular situations, of specific cultures and histories. Our investigation about the relationship between mining cooperatives, their national organization, and the Bolivian State demonstrates the crucial importance of considering historical aspects, of collective memory, some regional and others within the organizations themselves. The traditions, memories, and abilities incorporated in the mining organizations and in the political realm will influence the way in which different parts relate to one another, design their strategies, and adapt to changing circumstances. This topic is illustrated firstly through a historical and contemporary account of mining in Bolivia focused in the sector of small scale mining. This is followed by outlining the position that cooperative mining occupies in the country and the strategies and self esteem that they display. Next, our case study is addressed: the ASOBAL cooperative. In the national outline, like in our case study, we connect the positions and strategieswith themes of identity, memory, and place.

    2017-06-01

    Full Text Available This paper examines reconfigurations of household economies and agrobiodiversity through the experiences and responses of rural households to local manifestations of globalisation and environmental change in the Central Valley of Tarija, Bolivia, from the 1950s to the present. Research participant narratives from seven study communities document a widely experienced regional shift from rain-fed agriculture and pastured livestock production for household consumption to market-oriented production of regionally-specialised commodities. Particularly important to this reconfiguration are changing land access and use regimes, household responses to changing opportunities, discourses and social requirements related with ‘modernising lifestyles’, market integration and dependence, changing environmental and ecological conditions, and greater availability of consumer goods and technologies. We analyse how these processes have combined to reconfigure the range of livelihood possibilities available to rural households, or their ‘landscapes of possibility’, in ways that favour transition to specialised commodity production. Patterns of change in household agrobiodiversity use, however, are entwined with threads of persistence, underscoring the contingent nature of rural transitions and the role of local agency and creativity in responding to and sometimes shaping how globalisation unfolds. Examining rural transition through the experiences of households in particular contexts over time offers insights for development policy and practice to support producers’ ability to respond to globalisation and environmental change in ways they see as desirable and beneficial to their livelihoods and wellbeing.

    Firewood is the basic fuel source in rural Bolivia. A study was conducted in an Andean village of subsistence farmers to investigate human impact on wild firewood species. A total of 114 different fuel species was inventoried during fieldtrips and transect sampling. Specific data on abundance and growth height of wild firewood species were collected in thirty-six transects of 50 ×2 m(2). Information on fuel uses of plants was obtained from 13 local Quechua key participants. To appraise the impact of fuel harvest, the extraction impact value (EIV) index was developed. This index takes into account local participants' appreciation of (1) decreasing plant abundance; (2) regeneration capacity of plants; (3) impact of root harvesting; and (4) quality of firewood. Results suggest that several (sub-)woody plant species are negatively affected by firewood harvesting. We found that anthropogenic pressure, expressed as EIV, covaried with density of firewood species, which could entail higher human pressure on more abundant and/or more accessible species. The apparent negative impact of anthropogenic pressure on populations of wild fuel species is corroborated by our finding that, in addition to altitude, several anthropogenic variables (i.e. site accessibility, cultivation of exotics and burning practices) explain part of the variation in height of firewood species in the surroundings of Apillapampa.

    The mature fruits of three species of algarroba found in Bolivia (Prosopis chilensis (Molina) Stunz, P. alba Grisebach y P. nigra (Grisebach) Hieronymus) and of one of Brazil (P. juliflora (SW) DC) were analysed for some nutritional and antinutritional factors. P. nigra showed the highest levels of crude protein (11.33 g/100 g dry matter-DM) and ashes (4.12 g/100 g DM). P. juliflora presented the lowest levels of lipids (0.79 g/100 g DM), crude protein (8.84 g/100 g DM) and dietary fiber (40.15 g/100 g DM), and the highest levels of non reducing sugar (52.51 g/100 g DM) and in vitro protein digestibility (66.45%). Trypsin inhibitors concentration (0.29 to 9.32 UTI/mg DM) was inferior to that of raw soy; P. juliflora presented the higher values. Regarding saponin, hemagglutinin and poliphenol values, the levels found are considered low. As for nitrates, the levels found were higher than those reported for peas and beans, with P. chilensis presenting the highest value (2.92 g NO3(-)/kg DM). The levels of phytate varied from 1.31 a 1.53 g/100 g.

    Full Text Available In face of the global food crisis of 2007–2008, severe concerns arose about how developing countries would be affected by the extreme short-term fluctuations in international commodity prices. We examine the effects of the crisis on Bolivia, one of the poorest countries of the Americas. We focus on the effectiveness of the domestic policy interventions in preventing spillovers of the development of international food prices to domestic markets. Using a cointegration model, we study price interdependencies of wheat flour, sunflower oil and poultry. The analysis suggests that the policy measures taken had little effect on food security during the food crisis. Throughout the entire period, perfect price transmission between the Bolivian poultry and sunflower oil markets and the respective international reference markets existed. Bolivian prices were determined by international prices and the policy interventions in the markets of these two commodities were not found to have had an effect. The government’s large-scale wheat flour imports did not shield Bolivian consumers from the shocks of international prices.

    Municipal solid waste management (MSWM) is considered an important public health, economic and environmental concern, especially in developing countries. This paper introduces the situation of MSWM in La Paz (Bolivia) in 2016, and is based on the Wasteaware indicators and waste flow analysis, useful tools for classifying and comparing waste treatment and management plans among other countries. Taking into account the lack of technology in waste treatment and the presence of a developed informal sector, the paper analyses the main strengths and weak points for implementing a sustainable MSWM. The research conducted revealed that the MSWM of La Paz is not efficient with regard to collection, recycling (8%), financial sustainability, and equity of the service. At the same time, local Government and stakeholders are interested in implementing new MSWM methods for improving the current sanitary state of the city and many efforts were made over the last ten years. In general terms, La Paz could be considered as a good study area for developing plans for waste valorization, becoming an example for a low-middle income developing big city of Latin America. The study provided a few considerations about the affordability of the methodology applied and critically analyzed the case study proposed.

    Full Text Available Monazite [(Ce,ThPO4] from the Llallagua tin ore deposit in Bolivia is characterized by low radiogenic element contents. Previously reported field evidence and mineral associations suggest the mineral formed via direct precipitation from hydrothermal fluids. Monazite compositions thus may provide insight into characteristics of the fluids from which it formed. Chemical compositions of three Llallagua monazite grains were obtained using Electron Probe Microanalysis (EPMA, n = 64] and laser ablation mass spectrometer (LA-ICP-MS, n = 56. The mineral has higher amounts of U (123 ± 17 ppm than Th (39 ± 20 ppm (LA-ICP-MS, ±1σ. Grains have the highest amounts of fluorine ever reported for monazite (0.88 ± 0.10 wt %, EPMA, ±1σ, and F-rich fluids are effective mobilizers of rare earth elements (REEs, Y, and Th. The monazite has high Eu contents and positive Eu anomalies, consistent with formation in a highly-reducing back-arc environment. We speculate that F, Ca, Si and REE may have been supplied via dissolution of pre-existing fluorapatite. Llallagua monazite oscillatory zoning is controlled by an interplay of low (P + Ca + Si + Y and high atomic number (REE elements. We suggest monazite compositions provide insight into fluid geochemistry, mineral reactions, and tectonic settings of ore deposits that contain the mineral.

    Full Text Available We documented the history of land-use change and migration in eastern Bolivia in five temporal periods: pre-1976, 1976-1986, 1986-1991, 1991-2001, and 2001-2004. We included all land-cover types located below the natural montane tree line (~3000 m, including forest, savanna, scrubland, seasonal wetland, second-growth forest, pasture, and cropland. The rate of land-use change has increased from approximately 4.7 × 104 ha/yr in the 1960s to > 2.9 × 105 ha/yr in the most recent period. Land-use change was quantified for 10 groups within which cultural traditions and production systems are shared, including three nonmechanized indigenous groups, four mechanized farming groups, two cattle ranching groups, and the forest products sector. Mechanized Cruceño farmers and Andean indigenous colonists were responsible for most land-use change in the 1960s and 1970s; deforestation by the latter group increased to twice that by all other groups during 1986-1991, declined in the 1990s, and then increased again in the most recent period. In the last 15 years, land-use change by agro-industrialists specializing in soybean has become important, and cattle ranching based on cultivated pastures has surpassed land use by all other groups. When the rates of change increased for the three indigenous nonmechanized groups, they tended to decrease for the four nonindigenous mechanized groups, and vice versa.

    Uturuncu Volcano, located in the Altiplano-Puna region of the central Andes, near the border of Bolivia and Chile, has been shown to be inflating at a rate of 1-2 cm/yr over an area that is about 70 km wide. The PLUTONS project deployed 28 broadband seismometers around Uturuncu from April 2009 to October 2012. Several thousand shallow (depth earthquakes were recorded. Attenuation of seismic waves along travel paths for these local crustal earthquakes can be measured by calculating Q-values, which we have performed using the method of single station spectral ratios by Frankel (1982). Large scatter in the Q-values for various distances and travel times appear to be a function of variations in source depth, focal mechanism, and back azimuth. Preliminary Q-values were calculated for azimuths in 30° increments in sectors around each station. Estimates for Q range from about 60 to 700, with many showing a low Q in the direction of the summit from each station. This suggests that the volcanic pile is more highly attenuating than the surrounding crust.

    Full Text Available Very often, the production of silver causes devastating environmental issues, because of the use of toxic reagents like cyanide and mercury. Due to severe environmental damage caused by humans in the last decades, the social awareness regarding the sustainable production processes is on the rise. Terms like “sustainable” and “green” in product descriptions are becoming more and more popular and producers are forced to satisfy the rising environmental awareness of their customers. Within this work, an alternative environmental sound silver recovery process was developed for a vein type silver ore from Mina Porka, Bolivia. A foregoing characterization of the input material reveals its mineral composition. In the following mineral processing, around 92.9% silver was concentrated by separating 59.5 wt. % of non-silver minerals. Nitric acid leaching of the generated concentrate enabled a silver recovery of up to 98%. The dissolved silver was then separated via copper cementation to generate a metallic silver product of >99% purity. Summarizing all process steps, a silver yield of 87% was achieved in lab scale. A final upscaling trial was conducted to prove the process’ robustness. Within this trial, almost 4 kg of metallic silver with a purity of higher than 99.5 wt. % was produced.

    Full Text Available Chagas disease (CD profoundly affects the social and emotional dimensions of patients' lives, and disproportionately impacts poor, marginalized populations in Latin America. Biomedical treatment for CD fails to reach up to 99% of the people affected, and in any case seldom addresses the emotional health or socioeconomic conditions of patients. This study examines patient strategies for coping with CD in the department of Santa Cruz, Bolivia.In this ethnographic study, semistructured interviews took place from March-June 2013 with 63 patients who had previously tested positive for CD. During the fieldwork period, participant observation was conducted and patient family members, providers, community members, and public health officials were consulted.Patients often experienced emotional distress when diagnosed with CD, yet were generally unable to find biomedical treatment. Respondents stressed the need to avoid powerful emotions which would worsen the impact of CD symptoms. To manage CD, patients embraced a calm state of mind, described in Spanish as tranquilidad, which partially empowered them to return to a normal existence.In the perceived absence of biomedical treatment options, patients seek their own means of coping with CD diagnosis. Rather than fatalism or resignation, patients' emphasis on maintaining calm and not worrying about CD represents a pragmatic strategy for restoring a sense of normalcy and control to their lives. Programs focused on treatment of CD should remain mindful of the emotional and social impact of the disease on patients.

    Full Text Available Este trabajo explora, utilizando la metodología de la sociolingüística histórica, el multilingüismo y el contacto de lenguas en las minas de Potosí (Bolivia en la época colonial. Potosí fue el destino de la inmigración masiva durante su florecimiento económico y una de las ciudades más grandes en el mundo occidental en 1610. En las minas se desarrollaba un código separado, con un léxico especializado que contenía palabras de lenguas diferentes. Este léxico fue tan distinto que el primer vocabulario de lengua de minas fue escrito en 1610, y muchos han seguido desde esa fecha. El quechua jugaba un papel clave como lengua intermediaria entre dos formas de hablar: el lenguaje minero indígena de los yanaconas y mingas, probablemente una mezcla de castellano y quechua, y el lenguaje de los mitayos, posiblemente una mezcla de aimara y quechua. Las semejanzas entre aimara y quechua deben haber contribuido a esta posibilidad de lengua intermediaria.

    The seroprevalence of hepatitis A virus (HAV) is changing from high to intermediate endemicity in several Latin American countries, but the pattern in the Andean Latin American countries is unknown. A seroepidemiological survey (n = 436) of HAV in schoolchildren living in the Cochabamba region of Bolivia was conducted in 2010. A questionnaire was completed by parents to obtain demographic, socio-economic, and housing data, and blood samples were collected. The overall prevalence of HAV IgG was 95.4% (95% CI 93.5-97.4). The prevalence was higher in children aged 5-10 years (97%) and pre-adolescents aged 10-13 years (97.9%). The prevalence was also higher in subjects whose parents had a low level of education (99.4-99.5%), who lived in rural areas (98.7%), lived in municipalities with low urban development (99.1-100%), had water delivered at home from a tanker (99.4%), and spoke Quechua at home (99.5%). The descriptive and bivariate analysis suggested that no change in HAV epidemiology has occurred in Cochabamba. Copyright © 2013 Wiley Periodicals, Inc.

  11. The compatibility of agricultural intensification in a global hotspot of smallholder agrobiodiversity (Bolivia).

    Integrating the conservation of biodiversity by smallholder farmers with agricultural intensification is increasingly recognized as a leading priority of sustainability and food security amid global environmental and socioeconomic change. An international research project investigated the smallholder agrobiodiversity of maize (corn) in a global hotspot (Bolivia) undergoing significant intensification. Peach-based intensification was pronounced (300-400%) and prolonged (2000-2010) in study areas. Intensification and maize agrobiodiversity were found to co-occur within smallholder landscapes. Interactions of these field systems did not trigger land-change tipping points leading to landrace extirpation. By 2010 maize landraces in the study areas still demonstrated high levels of taxonomic and ecological biodiversity and contributed significantly to this crop's agrobiodiversity at national (31%) and hemispheric (3%) scales. Social and ecological resilience and in situ conservation of the maize agrobiodiversity by Bolivian smallholders was enabled through robust linkages to off-farm migration; resource access and asset capabilities among both traditional and nontraditional growers; landrace agroecology and food uses; and innovative knowledge and skills. The smallholders' resilience resulting from these linkages was integral to the conditional success of the in situ conservation of maize agrobiodiversity. Environment-development interactions both enabled smallholders' agrobiodiversity resilience and influenced the limits and vulnerability of agrobiodiversity. Scientific policy recommendations regarding land-use planning and sustainability analysis are targeted to specific Río+20 priorities for agrobiodiversity.

    The polygyny-fertility hypothesis states that polygyny is associated with reduced fertility for women and is supported by a large body of literature. This finding is important, because theoretical models of polygyny often differentiate systems based on the degree to which women are forced or willingly choose to enter polygynous marriages. The fact that polygyny tends to be associated with reduced fertility has been presented as evidence that polygyny is often less favourable for women, and that women must, therefore, be pressured into accepting such arrangements. Previous studies, however, have been hampered by the non-random assignment of women into monogamous and polygynous unions (i.e. self-selection), as differences between these groups of women might explain some of the effects. Furthermore, the vast majority of such studies focus on sub-Saharan populations. We address these problems in our analysis of women's fertility in polygynous marriages among the Tsimane of Bolivia. We offer a more robust method for assessing the impact of polygynous marriage on reproductive outcomes by testing for intra-individual fertility effects among first wives as they transition from monogamous to polygynous marriage. We report a significant link between polygyny and reduced fertility when including all cases of polygyny; however, this association disappears when testing only for intra-individual effects.

    This paper examines regional and temporal trends in mortality patterns among the Tsimane, a population of small-scale forager-horticulturalists in lowland Bolivia. We compare age-specific mortality in remote forest and riverine regions with that in more acculturated villages and examine mortality changes among all age groups over the past 50 years. Discrete-time logistic regression is used to examine impacts of region, period, sex, and age on mortality hazard. Villages in the remote forest and riverine regions show 2-4 times higher mortality rates from infancy until middle adulthood than in the acculturated region. While there was little change in mortality for most of the life course over the period 1950-1989, overall life expectancy at birth improved by 10 years from 45 to 53 after 1990. In both periods, over half of all deaths were due to infectious disease, especially respiratory and gastrointestinal infections. Accidents and violence accounted for a quarter of all deaths. Unlike typical patterns described by epidemiologic transition theory, we find a much larger period reduction of death rates during middle and late adulthood than during infancy or childhood. In the remote villages, infant death rates changed little, whereas death rates among older adults decreased sharply. We hypothesize that this pattern is due to a combination of differential access to medical interventions, a continued lack of public health infrastructure and Tsimane cultural beliefs concerning sickness and dying.

    Two long sediment records (cores LTO1-2B and LT01-3B) from Lake Titicaca, Bolivia/Peru, are compared with a previously analysed Holocene record from this lake (core NE98-1PC). The Holocene records of LT01-2B and NE98-1PC are similar. There are striking differences, however, between the MIS 5e sections of the long cores and the Holocene records. In these records, temperature is probably the dominant parameter that determines the total fossil pollen concentration and is used to time the onset and termination of deglaciation. In contrast, the relative and absolute abundance of specific taxa (e.g. Polylepis/Acaena, Chenopodiaceae) are indicators of relative moisture availability. Although the Holocene contains a period of aridity between ca. 8000 cal. yr BP and 4300 cal. yr BP, it is a minor event compared with the more extreme aridity of MIS 5e. Core LT01-3B showed similar trends during MIS 5e when compared to LT01-2B, as did NE98-1PC when comparing Holocene records. MIS 5e and the Holocene are markedly different interglacials, depicted by shifts in pollen concentration and taxa representation over time.

    Full Text Available El año de 1998 se recuerda por una crisis económica mundial que golpeó muy fuerte a Bolivia y socavó las bases económicas de la estabilidad política sobre la que se apoyó el neoliberalismo desde el año de 1986. El gobierno pretendió hacer pagar la crisis a los sectores populares, lo que desencadenó “el ciclo rebelde”, que derrotó primero en el 2000 la privatización trasnacional del agua, cercó las grandes ciudades varias veces en defensa de los sembrados de coca durante el primer lustro del siglo y reapropió para el Estado el servicio de gas en el año 2003. Al fragor de las luchas se construyó “la agenda de octubre”, que participó del conjunto de condiciones políticas necesarias para que las revueltas sociales se convirtieran en alternativa de poder, programa que llevaría a la victoria electoral de la presidencia de la república al indígena Evo Morales a finales del 2005.

    Esta presentación tiene como trasfondo el Plan Nacional de Desarrollo y pretende resaltar algunos de los logros del presidente Evo Morales y los desafíos que enfrenta en su tercer gobierno (2015-2019. Comienza revisando información demográfica básica, según el Censo de 2012, para luego centrarse en la economía: los hidrocarburos, la minería, la producción agropecuaria y la ecología. El boom de la quinua, la expansión de la frontera agrícola y la suspensión de la construcción de una carretera que atraviese el TIPNIS son algunos de los temas que se discuten. Internacionalmente, hay motivos de optimismo con relación a la demanda marítima de Bolivia, mientras que, a nivel nacional, el MAS aseguró una victoria parlamentaria en el año 2014. Las reformas menos exitosas son las del órgano judicial. La presentación termina revisando los movimientos sociales que permitieron la formación la de Asamblea Constituyente y el asunto de la autonomía municipal, departamental e indígena.

    Full Text Available Bolivia cierra una coyuntura en el cual la Asamblea Constituyente no sirvió sino para acentuar los problemas estructurales de la sociedad. Un nuevo proyecto de Constitución, cuya filosofía reivindica el carácter multiétnico de la sociedad y la aspiración colectiva de justicia social, no ha podido lograr la forma de un pacto social nacional ni una formulación sencilla favorable a la construcción de un nuevo Estado. Los cambios anunciados están trabados por el centralismo que el MAS ejerce en la toma de decisiones, por la ineficacia táctica de sus operadores políticos y por la dependencia de su política internacional. A pesar de un escenario interior conflictivo, la crisis boliviana podría atemperarse gracias a la influencia de los factores externos regionales: Brasil, potencia emergente, secundado por Argentina y Chile aspiran consolidar una zona libre de conflictos en el Cono Sur.

  20. Controlled but not cured: Structural processes and explanatory models of Chagas disease in tropical Bolivia.

    2015-11-01

    Dressler (2001:456) characterizes medical anthropology as divided between two poles: the constructivist, which focuses on the "meaning and significance that events have for people," and the structuralist, which emphasizes socioeconomic processes and relationships. This study synthesizes structuralist and constructivist perspectives by investigating how structural processes impact explanatory models of Chagas disease in a highly endemic area. The research took place from March-June 2013 through the Centro Medico Humberto Parra, a non-profit clinic servicing low income populations in Palacios, Bolivia and surrounding communities. Semistructured interviews (n = 68) and consensus analysis questionnaires (n = 48) were administered to people dealing with Chagas disease. In the interview narratives, respondents link Chagas disease with experiences of marginalization and rural poverty, and describe multilayered impediments to accessing treatment. They often view the disease as incurable, but this reflects inconsistent messages from the biomedical system. The consensus analysis results show strong agreement on knowledge of the vector, ethnomedical treatment, and structural factors related to Chagas disease. In interpreting Chagas disease, respondents account for the structural factors which place them at risk and impede access to care. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Samples from 17 free-ranging hunter-killed grey brocket deer (Mazama gouazoubira) in the Gran Chaco, Bolivia, were collected during June-August 1999. All 17 deer appeared to be in good condition at the time of death. Gross necropsies were performed, serum was collected for serologic evaluation of selected infectious disease agents, and feces and ectoparasites were collected for evaluation of internal and external parasites. Serologic tests were positive for antibodies against bovine respiratory syncytial virus and four Leptospira interrogans serovars, with questionable results for epizootic hemorrhagic disease virus serotypes 1 and 2. No antibodies were detected to Anaplasma marginale, Babesia bigemina, Babesia bovis, Babesia odocoilei, bluetongue virus (serotypes 2, 10, 11, 13, and 17), bovine viral diarrhea virus, Brucella abortus, foot-and-mouth disease virus, infectious bovine rhinotracheitis virus, Mycobacterium avium subsp. paratuberculosis, and parainfluenza-3 virus. Sixty-four percent (7/11) of the deer had endoparasites. Amblyomma spp. ticks were found on seven deer, flies of the family Hippoboscidae on six deer, and lice on six deer.

    New diseases known locally as 'hoja de perejil' of tomato (Lycopersicon esculentum Mill) and 'brotes grandes' of potato (Solanum tuberosum L.) were first recognized in surveys of production fields in Bolivia during 2000-2003. Alfalfa (Medicago sativa) witches' broom and little leaf diseases of native weeds Morrenia variegata and mora-mora (Serjania perulacea) were also identified near to production fields. Phytoplasma aetiology was attributed to each of these diseases following detection and initial identification of aster yellows group (16SrI) phytoplasmas in all five diseased plant species. While potato, alfalfa and mora-mora plants contained indistinguishable 16SrI-B strains, 'hoja de perejil' (THP) and morrenia little leaf (MVLL)-associated phytoplasma strains shared 97.5 % 16S rRNA gene sequence similarity with 'Candidatus Phytoplasma asteris' and related strains and <95 % similarity with all other 'Candidatus Phytoplasma' species. Phylogenetic analysis of 16S rRNA gene sequences indicated that the THP and MVLL phytoplasmas represent a novel lineage within the aster yellows (16SrI) group and, on the basis of unique 16S rRNA gene sequences, we propose that THP and MVLL phytoplasmas represent 'Candidatus Phytoplasma lycopersici', with THP as the reference strain.

The danger is that when mixed air and when inhaled can cause serious damage to the lungs, for the short life time that has radon and progeny for decay, damaging the pulmonary alveoli and reducing breathing capacity of the habitants, then causing polycythemia in some cases. The study was carried out in homes in the city of Potosi, Bolivia located at 4000 m. The quantification of radon gas and progeny was performed with the equipment Alpha-Zaeller-2 (Az-2), quantification was realized in 6 zones of the city of Potosi, chosen randomly. In each zone were carried out measurements in 40 homes (2 rooms more permanent), both day and night, for a period of 3 days in two different seasons and with concentrations of average humidity of 20, 50 and 80%. The values obtained for each period vary depending on the season and 30 to 50% of the allowable values given by the EPA and Who for housing. (Author)

  4. When is deliberate killing of young children justified? Indigenous interpretations of infanticide in Bolivia.

    In the Andes, as elsewhere, infanticide is a difficult challenge that remains largely undocumented and misunderstood. From January to March 2004 we used community-based vital event surveillance systems, discussions with health staff, ethnographic interviews, and focus group discussions among Aymara men and women from two geographically distinct sites in the Andes of Bolivia to provide insights into the practice of infanticide. We noted elevated mortality at both sites. In one location, suspected causes of infanticide were especially high for girls. We also observed that community members maintain beliefs that justify infanticide under certain circumstances. Among the Aymara, justification for infanticide was both biological (deformities and twinship) and social (illegitimate birth, family size and poverty). Communities generally did not condemn killing when reasons for doing so were biological, but the taking of life for social reasons was rarely justified. In this cultural context, strategies to address the challenge of infanticide should include education of community members about alternatives to infanticide. At a program level, planners and implementers should target ethnic groups with high levels of infanticide and train health care workers to detect and address multiple warning signs for infanticide (for example, domestic violence and child maltreatment) as well as proxies for infant neglect and abuse such as mother/infant separation and bottle use.

    Trypanosoma cruzi (Tc) infection is usually acquired in childhood in endemic areas, leading to Chagas disease, which progresses to Chagas cardiomyopathy in 20-30% of infected individuals over decades. The pathogenesis of Chagas cardiomyopathy involves the host inflammatory response to T. cruzi, in which upstream caspase-1 activation prompts the cascade of inflammatory chemokines/cytokines, cardiac remodeling, and myocardial dysfunction. The aim of the present study was to examine the association of two caspase-1 single nucleotide polymorphisms (SNPs) with cardiomyopathy. We recruited infected (Tc+, n = 149) and uninfected (Tc-, n = 87) participants in a hospital in Santa Cruz, Bolivia. Cardiac status was classified (I, II, III, IV) based on Chagas cardiomyopathy-associated electrocardiogram findings and ejection fractions on echocardiogram. Genotypes were determined using Taqman probes via reverse transcription-polymerase chain reaction of peripheral blood DNA. Genotype frequencies were analyzed according to three inheritance patterns (dominant, recessive, additive) using logistic regression adjusted for age and sex. The AA allele for the caspase-1 SNP rs501192 was more frequent in Tc+ cardiomyopathy (classes II, III, IV) patients compared to those with a normal cardiac status (class I) [odds ratio (OR) = -2.18, p = 0.117]. This trend approached statistical significant considering only Tc+ patients in class I and II (OR = -2.64, p = 0.064). Caspase-1 polymorphisms may play a role in Chagas cardiomyopathy development and could serve as markers to identify individuals at higher risk for priority treatment.

    Since 2005, great progress has been made in health care provision to patients with terminal renal failure in Bolivia. Access to dialysis and transplantation is regulated by the Ministry of Health, based on clinical criteria, applied equitably, without favoritism or discrimination based on race, sex, economic means, or political power. Until December 2013, there were no restrictions in dialysis and transplantation in Health Insurance institutions, but they covered only 30% of the population. Now the remaining 70% has access to free dialysis funded by the communities where patients live, with funds coming from the government and taxes on oil products. More than 2,231 people are getting dialysis, reaching a population growth of >60% annually. The number of hemodialysis units has increased by >200% (60 units), making access easier for end-stage renal failure patients. Treatment protocols have been drawn up to guarantee the best quality of life for the patients. The Law on Donation and Transplantation was enacted in 1996, and Supplementary Regulations were enacted in 1997 with various amendments over the past 5 years. A National Transplant Coordination Board, working under the National Renal Health Program, supervises and regulates transplants and promotes deceased-donor transplantation in an attempt to cover the demand for donors. Rules have been drawn up for accreditation of transplant centers and teams to guarantee the best possible conditions and maximum guaranties. Since January 2014, the National Renal Health Program has been providing free kidney transplants from living donors. Copyright © 2016 Elsevier Inc. All rights reserved.

    We report the results of an investigation of a small outbreak of hantavirus pulmonary syndrome in 2002 in the Department of Santa Cruz, Bolivia, where the disease had not previously been reported. Two cases were initially reported. The first case was a physician infected with Laguna Negra virus during a weekend visit to his ranch. Four other persons living on the ranch were IgM antibody-positive, two of whom were symptomatic for mild hantavirus pulmonary syndrome. The second case was a migrant sugarcane worker. Although no sample remained to determine the specific infecting hantavirus, a virus 90% homologous with Río Mamoré virus was previously found in small-eared pygmy rice rats (Oligoryzomys microtis) trapped in the area. An antibody prevalence study conducted in the region as part of the outbreak investigation showed 45 (9.1%) of 494 persons to be IgG positive, illustrating that hantavirus infection is common in Santa Cruz Department. Precipitation in the months preceding the outbreak was particularly heavy in comparison to other years, suggesting a possible climatic or ecological influence on rodent populations and risk of hantavirus transmission to humans. Hantavirus infection appears to be common in the Santa Cruz Department, but more comprehensive surveillance and field studies are needed to fully understand the epidemiology and risk to humans.

    The natural transmission of dengue virus from an infected female mosquito to its progeny, namely the vertical transmission, was researched in wild caught Aedes aegypti during an important outbreak in the town of Santa Cruz de la Sierra, Bolivia. Mosquitoes were collected at the preimaginal stages (eggs, larvae and pupae) then reared up to adult stage for viral detection using molecular methods. Dengue virus serotypes 1 and 3 were found to be co-circulating with significant higher prevalence in male than in female mosquitoes. Of the 97 pools of Ae. aegypti (n = 635 male and 748 female specimens) screened, 14 pools, collected in February-May in 2007, were found positive for dengue virus infection: five DEN-1 and nine DEN-3. The average true infection rate (TIR) and minimum infection rate (MIR) were respectively 1.08% and 1.01%. These observations suggest that vertical transmission of dengue virus may be detected in vectors at the peak of an outbreak as well as several months before an epidemic occurs in human population.

    Chagas disease (CD) profoundly affects the social and emotional dimensions of patients' lives, and disproportionately impacts poor, marginalized populations in Latin America. Biomedical treatment for CD fails to reach up to 99% of the people affected, and in any case seldom addresses the emotional health or socioeconomic conditions of patients. This study examines patient strategies for coping with CD in the department of Santa Cruz, Bolivia. In this ethnographic study, semistructured interviews took place from March-June 2013 with 63 patients who had previously tested positive for CD. During the fieldwork period, participant observation was conducted and patient family members, providers, community members, and public health officials were consulted. Patients often experienced emotional distress when diagnosed with CD, yet were generally unable to find biomedical treatment. Respondents stressed the need to avoid powerful emotions which would worsen the impact of CD symptoms. To manage CD, patients embraced a calm state of mind, described in Spanish as tranquilidad, which partially empowered them to return to a normal existence. In the perceived absence of biomedical treatment options, patients seek their own means of coping with CD diagnosis. Rather than fatalism or resignation, patients' emphasis on maintaining calm and not worrying about CD represents a pragmatic strategy for restoring a sense of normalcy and control to their lives. Programs focused on treatment of CD should remain mindful of the emotional and social impact of the disease on patients.

    In Bolivia, metal mining activities since historical times have been one of the most important sources of environmental pollution. This is the case of the National Area of Apolobamba Integrated Management (ANMIN of Apolobamba) in La Paz, Bolivia, where intense gold mining activities have been carried out from former times to the present, with very little gold extraction and very primitive mineral processing technology; in fact, mercury is still being used in the amalgam processes of the gold concentration, which is burned outdoors to recover the gold. Sunchullí is a representative mining district in ANMIN of Apolobamba where mining activity is mainly gold extraction and its water effluents go to the Amazonian basin; in this mining district the productivity of extracted mineral is very low but the processes can result in heavy-metal contamination of the air, water, soils and plants. Due to its high toxicity, the contamination by arsenic and mercury create the most critical environmental problems. In addition, some other heavy metals may also be present such as lead, copper, zinc and cadmium. These heavy metals could be incorporated in the trophic chain, through the flora and the fauna, in their bio-available and soluble forms. Inhabitants of this area consume foodcrops, fish from lakes and rivers and use the waters for the livestock, domestic use, and irrigation. The aim of this work was to evaluate the heavy metals pollution by gold mining activities in Sunchullí area. In Sunchullí two representative zones were distinguished and sampled. Zone near the mining operation site was considered as affected by mineral extraction processes, while far away zones represented the non affected ones by the mining operation. In each zone, 3 plots were established; in each plot, 3 soil sampling points were selected in a random manner and analysed separately. In each sampling point, two samples were taken, one at the surface, from 0-5 cm depth (topsoil), and the other between 5

    2004-03-01

    Full Text Available Fossil plants belonging to the morphogenera Glossopteris, Pecopteris and Asterotheca were collected from the upper part of the Chutani Formation (Titicaca Group, near the town of San Pablo de Tiquina, on the southeastern shore of Lake Titicaca (northern Altiplano, Bolivia. This paper presents the first description of specimens of the morphogenus Glossopteris from Bolivia. The Bolivian specimens of Glossopteris consist of poorly-preserved impressions, although they present the diagnostic features of this morphogenus. They are fragments of leaves with secondary veins of taeniopterid-type, typical of glossopterids from Late Permian deposits of Gondwana. The only species of Pecopteris confirmed in the first part of this study, i.e. P. dolianitii Rösler and Rohn (see Vieira et al. 2004, was previously reported from the Late Permian beds of the Rio do Rasto and Estrada Nova formations in the Paraná Basin (southern Brazil. Therefore, a Late Permian age is proposed for the fossil plant-bearing beds of the Chutani Formation based on the analyzed assemblage. The phytogeographic implications of this new find are briefly analyzed.Plantas fósseis, pertencentes aos morfo-gêneros Glossopteris, Pecopteris e Asterotheca, foram coletadas na porção superior da seção aflorante da Formação Chutani, próxima ao povoado de San Pablo de Tiquina, sudeste do lago Titicaca (Altiplano norte, Bolívia. Este trabalho apresenta a primeira descrição de espécimes do morfo-gênero Glossopteris provenientes da Bolívia. Os espécimes estudados de Glossopteris consistem em impressões foliares pobremente preservadas nas quais feições diagnósticas estão presentes. Os fragmentos foliares apresentam venação secundária do tipo teniopteróide, uma característica típica de glossopterídeas encontradas em depósitos do Permiano Superior do Gondwana.

    Global carbon cycle mainly depends on the soil organic matter (SOM). Some reducction of climatic impact techiques are related to the increase of the soil organic carbon (SOC) contents in order to elevate atmospherical carbon inputs. Kinetic mechanisms of the SOC are differents due to the complex interation between biological, physical and chemical processes in the soil. For a full understanding of the SOM contribution to the carbon cycle in the soil, the SOC contents should be addressed. The vicuna (Vicugna vicugna) is an endangered species which belongs to camelid family. Its natural habitat is located in highland grasses in the Andes Montain Range, above 4,000 m.a.s.l. In Bolivia the vicuna is distributed around some andean regions such as Apolobamba. It is a protected area located in the Northwest of Bolivia where native inhabitants carry out a sustainable management of the vicuna. This activity is considered within a programme to improve economical conditions in the area. The vicuna lives in the same habitat than other cattle camelid like alpaca (Lama pacos). The soil is an essential natural resource in the vicuna development and the biodiversity conservation due to its role to support the native vegetation in Apolobamba. The objectives of this research were: (i) the quantification of SOC contents, (ii) the study of the SOC quality and (iii) the determination of the soil degradation degree in some zones in Apolobamba. Eight zones or census places, separated areas with geographic accidents, with different vicuna and alpaca densities were selected: Ulla-Ulla and Killu (low density), Ucha-Ucha and Wakampata (medium density), Sucondori and Caballchiñuni (high density) and Puyo-Puyo and Japu (very high density). One soil profile was taken and three sampling plots were determined in each zone. Three sampling points were selected in each plot and surface (0-5 cm) and subsurface samples (5-15 cm) were collected. Total carbon, total organic carbon (TOC) and water

    Full Text Available Based on a case study of Charazani – Bolivia, this article outlines the understanding of adaptive strategies to cope with climate change and its impact on environmental and socioeconomic conditions that are affecting rural livelihoods. Mainly qualitative methods were used to collect and analyze data following the framework for vulnerability assessments of a socio-ecological system. Climate data reveals an increase of precipitation and temperature during the last decades. Furthermore the occurrence of extreme weather events, particularly drought, frost, hailstorms and consequently landslides and fire are increasing. Local testimonies highlight these events as the principle reasons for agricultural losses. This climatic variability and simultaneous social changes were identified as the drivers of vulnerability. Yet, several adaptive measures were identified at household, community and external levels in order to cope with such vulnerability; e.g. traditional techniques in agriculture and risk management. Gradually, farmers complement these activities with contemporary practices in agriculture, like intensification of land use, diversification of irrigation system and use of artificial fertilizers. As part of a recent trend community members are forced to search for new off-farm alternatives beyond agriculture for subsistence. Despite there is a correspondingly large array of possible adaptation measures that families are implementing, local testimonies point out, that farmers often do not have the capacity and neither the economical resources to mitigate the risk in agricultural production. Although several actions are already considered to promote further adaptive capacity, the current target is to improve existing livelihood strategies by reducing vulnerability to hazards induced by climate change.

  17. Calcite Twin Analysis in the Central Andes of Northern Argentina and Southern Bolivia

    The use of calcite twinning to infer compression directions and strain axes patterns has been applied widely in both fold and thrust belts, and continental interiors. Calcite twinning is noted to be one of the most precise methods for determining the internal strain of deformed rocks. Until now, such data from the deformed plate boundary of the Central Andes were lacking. This study has examined twinning orientations along the deformed Andean foreland (southern Bolivia and northern Argentina) from -25 to -20 latitude. In the Central Andes, we find an abundance of calcite twins in intervals of the Cretaceous age Yacorite limestone. Twin samples were collected, measured for orientation and type (I and II can be best used for strain analysis), and processed using the Groshong method, to give resultant strain tensors. The orientations of the twin short axes trend mostly NE-SW, which is close to the plate convergence direction. However, in a limited number of samples from the north, adjacent to the southern culmination of the active Subandean fold thrust belt, they trend NW-SE. This difference may be related to the more active, or more recent, shortening of the southern portion of the Eastern Cordillera, south of the culmination of the Subandean belt. This implies that twin short axes vary consistently with respect to geographic location and local tectonic regime. NW-SE trends in the northern region match well with fault kinematic studies in rocks pre-dating the San Juan del Oro unconformity (9-10 Ma). NE-SW trends in the south could correspond to much younger (~1-3 Ma) fault kinematic trends. In the Eastern Cordillera, where there is present day tectonic activity, the plunges of the twin short axes are found to be almost horizontal. This suggests that the twins were formed after folding occurred.

    Mobile health (m-health) work in low- and middle-income countries (LMICs) mainly consists of small pilot programs with an unclear path to scaling and dissemination. We describe the deployment and testing of an m-health platform for non-communicable disease (NCD) self-management support in Bolivia. Three hundred sixty-four primary care patients in La Paz with diabetes or hypertension completed surveys about their use of mobile phones, health and access to care. One hundred sixty-five of those patients then participated in a 12-week demonstration of automated telephone monitoring and self-management support. Weekly interactive voice response (IVR) calls were made from a platform established at a university in La Paz, under the direction of the regional health ministry. Thirty-seven percent of survey respondents spoke indigenous languages at home and 38% had six or fewer years of education. Eighty-two percent had a mobile phone, 45% used text messaging with a standard phone, and 9% had a smartphone. Smartphones were least common among patients who were older, spoke indigenous languages, or had less education. IVR program participants completed 1007 self-management support calls with an overall response rate of 51%. IVR call completion was lower among older adults, but was not related to patients' ethnicity, health status, or healthcare access. IVR health and self-care reports were consistent with information reported during in-person baseline interviews. Patients' likelihood of reporting excellent, very good, or good health (versus fair or poor health) via IVR increased during program participation and was associated with better medication adherence. Patients completing follow-up interviews were satisfied with the program, with 19/20 (95%) reporting that they would recommend it to a friend. By collaborating with LMICs, m-health programs can be transferred from higher-resource centers to LMICs and implemented in ways that improve access to self-management support among

    To assess the adequacy of energy and nutritional intakes compared to recommended daily intakes (RDIs) in schoolchildren from the Cochabamba region (Bolivia) and to determine micronutrient intake distributions across different ages and genders. This nutritional study (n = 315) was part of a larger population-based crosssectional study (the "Bolkid" survey) that collected data on schoolchildren 5-16 years old in 2010 in the Cochabamba region. Information about food intake was gathered with a semiquan-titative, food-frequency, parent-administered questionnaire about l2 months before the study. Descriptive and bivariate analyses of energy and nutrient intakes were assessed. For all ages studied and both genders, the average energy and micronutrient intakes were acceptable but below the requirements. The diet included high amounts of fiber, some minerals (iron, magnesium, phosphorus, potassium, sodium), and vitamins (pantothenic acid, niacin, vitamins B2, B12, C, and E), but was low in calcium and vitamin D. However, more than half the children had insufficient energy intake, and low calcium, vitamin A, and vitamin D intakes, according to RDIs adjusted for age and gender; one-third of the children had insufficient folate and magnesium intakes; and adolescent girls had low iron intakes. Regardless of recommendations or demographic characteristics, the vast majority of children in Cochabamba consumed insufficient energy and too little calcium, folate, magnesium, and vitamin A and D. In addition, adolescent girls consumed insufficient iron. Higher energy intake for schoolchildren through increased food availability, frequency, and size portions in daily meals should be a priority for Bolivian public health institutions.

    A new GPS-derived surface velocity field for the central Andean backarc permits an assessment of orogenic wedge deformation across the southern Subandes of Bolivia, where recent studies suggest that great earthquakes (>Mw 8) are possible. We find that the backarc is not isolated from the main plate boundary seismic cycle. Rather, signals from subduction zone earthquakes contaminate the velocity field at distances greater than 800 km from the Chile trench. Two new wedge-crossing velocity profiles, corrected for seasonal and earthquake affects, reveal distinct regions that reflect (1) locking of the main plate boundary across the high Andes, (2) the location of and loading rate at the back of orogenic wedge, and (3) an east flank velocity gradient indicative of décollement locking beneath the Subandes. Modeling of the Subandean portions of the profiles indicates along-strike variations in the décollement locked width (WL) and wedge loading rate; the northern wedge décollement has a WL of ~100 km while accumulating slip at a rate of ~14 mm/yr, whereas the southern wedge has a WL of ~61 km and a slip rate of ~7 mm/yr. When compared to Quaternary estimates of geologic shortening and evidence for Holocene internal wedge deformation, the new GPS-derived wedge loading rates may indicate that the southern wedge is experiencing a phase of thickening via reactivation of preexisting internal structures. In contrast, we suspect that the northern wedge is undergoing an accretion or widening phase primarily via slip on relatively young thrust-front faults.

  2. Biotic nitrosation of diclofenac in a soil aquifer system (Katari watershed, Bolivia).

    Up till now, the diclofenac (DCF) transformation into its nitrogen-derivatives, N-nitroso-DCF (NO-DCF) and 5-nitro-DCF (NO2-DCF), has been mainly investigated in wastewater treatment plant under nitrification or denitrification processes. This work reports, for the first time, an additional DCF microbial mediated nitrosation pathway of DCF in soil under strictly anoxic conditions probably involving codenitrification processes and fungal activities. This transformation pathway was investigated by using field observations data at a soil aquifer system (Katari watershed, Bolivia) and by carrying out soil slurry batch experiments. It was also observed for diphenylamine (DPA). Field measurements revealed the occurrence of NO-DCF, NO2-DCF and NO-DPA in groundwater samples at concentration levels in the 6-68s/L range. These concentration levels are more significant than those previously reported in wastewater treatment plant effluents taking into account dilution processes in soil. Interestingly, the p-benzoquinone imine of 5-OH-DCF was also found to be rather stable in surface water. In laboratory batch experiments under strictly anoxic conditions, the transformation of DCF and DPA into their corresponding N-nitroso derivatives was well correlated to denitrification processes. It was also observed that NO-DCF evolved into NO2-DCF while NO-DPA was stable. In vitro experiments showed that the Fisher-Hepp rearrangement could not account for NO2-DCF formation. One possible mechanism might be that NO-DCF underwent spontaneous NO loss to give the resulting intermediates diphenylaminyl radical or nitrenium cation which might evolve into NO2-DCF in presence of NO2 radical or nitrite ion, respectively.

    In this work, the aerial regime of an aridisol with a loam clay-sandy texture of the central area of the high plateau of Bolivia, was determined as a function of the monthly volumetric moisture (using mean values) and the total porosity of the horizons Ap (0-19 cm), Bt (19-49 cm) and Cca (49-70 cm), Bt (19-49 cm) and Cca (49-70 cm). Values of moisture were determined during three year: 1983-84, 1984-5 and 1985-86 with the neutron probe. Fluctuations of the soil air content during the research period in the Ap and Bt horizons were strictly dependant on the precipitations and their seasonal variations due to porosity which was considered constant. Because this work was made in a soil with natural vegetation cover and without physical changes produced by tillage. The soil air content in the sandy Ap horizon showed higher values and greater difference (4-27%) than inferior horizons rich in clay (2-14%). The results were compared with quotes from the Czechoslovakian literature on the requirement of soil air content for certain crops: 15-35% for potatoes, 10-15% for cereals and 5-10% for pastures. This aridisol showing certain properties as clay horizons from 20 cm depth, unstable structure and insufficient air contents, can only be used for cereals and pastures. The use of these soils could be extended to crops with greater air requirements, if the water and aerial regimes are improved with the help of subsoilers, deepening the top soil and incorporating manure and green manure for improving the soil structure and porosity

  5. Putative panmixia in restricted populations of Trypanosoma cruzi isolated from wild Triatoma infestans in Bolivia.

    Full Text Available Trypanosoma cruzi, the causative agent of Chagas disease, is subdivided into six discrete typing units (DTUs; TcI-TcVI of which TcI is ubiquitous and genetically highly variable. While clonality is the dominant mode of propagation, recombinant events play a significant evolutive role. Recently, foci of wild Triatoma infestans have been described in Bolivia, mainly infected by TcI. Hence, for the first time, we evaluated the level of genetic exchange within TcI natural potentially panmictic populations (single DTU, host, area and sampling time. Seventy-nine TcI stocks from wild T. infestans, belonging to six populations were characterized at eight microsatellite loci. For each population, Hardy-Weinberg equilibrium (HWE, linkage disequilibrium (LD, and presence of repeated multilocus genotypes (MLG were analyzed by using a total of seven statistics, to test the null hypothesis of panmixia (H0. For three populations, none of the seven statistics allowed to rejecting H0; for another one the low size did not allow us to conclude, and for the two others the tests have given contradictory results. Interestingly, apparent panmixia was only observed in very restricted areas, and was not observed when grouping populations distant of only two kilometers or more. Nevertheless it is worth stressing that for the statistic tests of "HWE", in order to minimize the type I error (i. e. incorrect rejection of a true H0, we used the Bonferroni correction (BC known to considerably increase the type II error ( i. e. failure to reject a false H0. For the other tests (LD and MLG, we did not use BC and the risk of type II error in these cases was acceptable. Thus, these results should be considered as a good indicator of the existence of panmixia in wild environment but this must be confirmed on larger samples to reduce the risk of type II error.

    2006-12-01

    Full Text Available On 2 July 2006, Bolivia held a national referendum about departamental autonomy as part of the process of state decentralization and as an institutional response to the dire political and social crisis. The inclusion in the constitution of figures such as referendum, constitutional assembly and citizen legislative initiation was the response to the social demands and unrest given under the framework of semi-direct democracy which allowed for an institutional solution to them. Even though the law that called for the referendum defines its national character, in several articles it states that a regime of departamental autonomy will apply immediately after the new Constitution is ratified in those departments where the referendum question was approved by a simple majority of the vote. This dual interpretation with regards to the mandatory nature of the results — at the national or the departamental level — is added to the debate about the nature of the autonomies.The party of the government, whose position won in the referendum and won a majority of the constitutional assembly, sketches a proposal that includes different versions of autonomy — indigenous, regional, provincial, cantonal, communal — that run counter, in some instances, to the departamental autonomies. In sum, the referendum on departamental autonomy, far from solving the problem, has transfered it to the constitutional assembly which puts at risk the democratic legitimacy of its decisions given that the new constitution must answer the demands of diverse political and social actors. Aside from these dynamics, this experience of citizen participation in the decisiom-making process is an example of the positive impact of an institutional reform in the strengthening of the democratic legitimacy and the efficacy of political institutions.

    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.

    This study examines patterns of growth and nutritional status of indigenous Tsimane' children under 9 years of age (n = 199 boys and 210 girls), based on a cross-sectional sample from 58 villages from the Beni Deparment of lowland Bolivia. Compared with US children, Tsimane' children are quite short, with linear growth tracking at or below the US 5th centile in both sexes. The prevalence of low height-for-age ("stunting;" HA Z-scores Tsimane' children approximates the US median, with the prevalence of low weight-for-height ("wasting"; WH Z-scores Tsimane' boys and girls are leaner than their US peers, but their levels of body fatness are not so low as to indicate severe energy stress. Arm muscularity of Tsimane' children is similar to that of their US age peers, and this suggests that they are not experiencing acute protein malnutrition. Variation in measures of nutritional status of Tsimane' children is modestly correlated with village-level differences. Degree of isolation, as measured by distance to urban centers or to primary forest, was not a strong predictor of children's anthropometric status. Rather, in both boys and girls, nutritional status was most strongly associated with number of teachers in the village, a measure of access to education. Comparative analyses indicate that high levels of statural growth stunting are common among indigenous populations throughout lowland South America. This problem appears to be largely attributable to poor dietary quality (diets low in key micronutrients) and high disease loads. Further research is needed to identify the specific causes and potential interventions for the high rates of childhood growth stunting in this region. (c) 2004 Wiley-Liss, Inc.

    Katherine Yih-Jia Fu

    Full Text Available Abstract INTRODUCTION: Trypanosoma cruzi (Tc infection is usually acquired in childhood in endemic areas, leading to Chagas disease, which progresses to Chagas cardiomyopathy in 20-30% of infected individuals over decades. The pathogenesis of Chagas cardiomyopathy involves the host inflammatory response to T. cruzi, in which upstream caspase-1 activation prompts the cascade of inflammatory chemokines/cytokines, cardiac remodeling, and myocardial dysfunction. The aim of the present study was to examine the association of two caspase-1 single nucleotide polymorphisms (SNPs with cardiomyopathy. METHODS: We recruited infected (Tc+, n = 149 and uninfected (Tc−, n = 87 participants in a hospital in Santa Cruz, Bolivia. Cardiac status was classified (I, II, III, IV based on Chagas cardiomyopathy-associated electrocardiogram findings and ejection fractions on echocardiogram. Genotypes were determined using Taqman probes via reverse transcription-polymerase chain reaction of peripheral blood DNA. Genotype frequencies were analyzed according to three inheritance patterns (dominant, recessive, additive using logistic regression adjusted for age and sex. RESULTS: The AA allele for the caspase-1 SNP rs501192 was more frequent in Tc+ cardiomyopathy (classes II, III, IV patients compared to those with a normal cardiac status (class I [odds ratio (OR = −2.18, p = 0.117]. This trend approached statistical significant considering only Tc+ patients in class I and II (OR = −2.64, p = 0.064. CONCLUSIONS: Caspase-1 polymorphisms may play a role in Chagas cardiomyopathy development and could serve as markers to identify individuals at higher risk for priority treatment.

    During the period of the Transatlantic Slave Trade (TAST) some enslaved Africans were forced to move to Upper Peru (nowadays Bolivia). At first they were sent to Potosí, but later to the tropical Yungas valley where the Spanish colonizers established a so-called "hacienda system" that was based on slave labor, including African-descendants. Due to their isolation, very little attention has been paid so far to 'Afro-Bolivian' communities either within the research field of TAST or in genetic population studies. In this study, a total of 105 individuals from the Yungas were sequenced for their mitochondrial DNA (mtDNA) control region, and mitogenomes were obtained for a selected subset of these samples. We also genotyped 46 Ancestry Informative Markers (AIM) in order to investigate continental ancestry at the autosomal level. In addition, Y-chromosome STR and SNP data for a subset of the same individuals was also available from the literature. The data indicate that the partitioning of mtDNA ancestry in the Yungas differs significantly from that in the rest of the country: 81% Native American, 18% African, and 1% European. Interestingly, the great majority of 'Afro-descendant' mtDNA haplotypes in the Yungas (84%) concentrates in the locality of Tocaña. This high proportion of African ancestry in the Tocaña is also manifested in the Y-chromosome (44%) and in the autosomes (56%). In sharp contrast with previous studies on the TAST, the ancestry of about 1/3 of the 'Afro-Bolivian' mtDNA haplotypes can be traced back to East and South East Africa, which may be at least partially explained by the Arab slave trade connected to the TAST.

    Local management of rural power supply is being evaluated in a joint research project conducted by Tanzania Electric Supply Company Limited (TANESCO) and Stockholm Environment Institute (SEI) on new approaches to management and organization of rural electrification. The study is based on literature, and on data from eight visited local organizations for management of power supply in Bolivia (4), India (1) and Nepal (3). Common for these countries is that the national, rural electrification programmes have encountered difficulties. Governments have failed to generate enough funds from existing power supply systems to cover the cost for a continued rural electrification. In cases where large private companies exist, they have had few incentives for expanding into rural areas since it is often not profit making. A third category may be defined as local initiators to power supply, private or co-operative. In all these countries, locally managed power supply systems have developed as a complement to governmental and other large scale programmes. The national policies pertaining to rural power supply in general and local management thereof in particular are described for each country. From the study, it appears that local management of rural power supply is a feasible approach in developing countries. Local management of rural power supply can slightly lower the costs of electrification, and it may help accelerate the pace of load development in newly electrified areas. For successful local organizations though, the most significant factor appears to be local peoples` willingness to develop their own area. Important though, is that proper financial and technical assistance is provided the local organizations. Crucial for sound external assistance is that the national rural electrification policies are clear and consistent. 53 refs, 1 fig, 11 tabs

  14. Constraining Glacial Runoff Contributions to Water Resources in the Cordillera Real, Bolivia using Environmental Tracers

    Warming temperatures in recent decades have contributed to substantial reductions in glaciers in many mountain regions around the globe, including the South American Andes. Melting of these glaciers taps water resources accumulated in past climates, and the diminishing ice marks a decrease in a nonrenewable water source that begs the question: how will future water supplies be impacted by climate change. Water resource management and climate adaptation efforts can be informed by knowledge of the extent to which glaciers contribute to seasonal streamflows, but remote locations and scant monitoring often limit this quantification. In Bolivia, more than two million people draw water from watersheds fed, in part, by glaciers. The amount to which these glaciers contribute to the water supply, however, is not well constrained. We apply elemental and isotopic tracers in an end-member mixing model to quantify glacial runoff contributions to local water supplies. We present oxygen and deuterium isotopes and major anion concentrations (sulfate and chloride) of shallow groundwater, streams, reservoirs, small arroyos, and glacial runoff. Isotopic and anion mixing models suggest between 45-67% of the water measured in high altitude streams originated from within the glacial footprint during the 2011 wet season, while glacial runoff contributed about 42-53% of the water in reservoirs in the 2012 dry season. Data also show that shallow groundwater is connected to glacial-fed streams. Any future decrease in glacial runoff may contribute to a reduction in surface water supplies and lower groundwater levels downstream, perhaps below the depth of hand-dug wells common in rural communities.

    Background In the context of a rapid increase of dengue cases in the Americas, a monitoring system based on systematic serological control (IgM) of patients consulting for suspected dengue was developed in Bolivia at the end of the 1990s. In the most affected city of Santa Cruz, this system was complemented by an entomological surveillance program based on periodical search for immature stages of Aedes aegypti in dwelling water-holding containers. Here, we analyze these data and describe dengue patterns over 6 years (2002–2008), highlighting the spatial distribution of patients and vectors. Methodology /Principal Findings Data mining concerned six annual epidemic cycles (2002–2008), with continuous serological and clinical results and entomological data from 16 surveys, examined at the scales of 36 urban areas and four concentric areas covering the entire city. Annual incidence varied from 0.28‰ to 0.95‰; overall incidence was higher in women and adults, and dengue dynamics followed successive periods of high (January–June) and low (July–December) transmission. Lower numbers of cases from the city center to the periphery were observed, poorly related to the more homogeneous and permanent distribution of A. aegypti. "Plant pots" were a major vector source in the city center, and "Tires" and "Odds and ends" beyond the second ring of the city. Conclusions/Significance Over the years, the increasing trend of dengue cases has been highlighted as well as its widespread distribution over the entire city, but an underestimation of the number of cases is strongly suspected. Contrary to popular belief, the city center appears more affected than the periphery, and dengue is not particularly related to waste. Interestingly, the clinical diagnosis of dengue by physicians improved over the years, whatever the gender, age and residential area of suspected cases. PMID:25706631

  16. Astronomically Forced Hydrology of the Late Cretaceous Sub-tropical Potosí Basin, Bolivia

    Orbital forcings paced the ice ages of the Pleistocene, demonstrating that periodic variations in the latitudinal distribution of insolation amplified by ice-albedo feedbacks can guide global climate. How these forcings operate in the hot-houses that span most of the planet's history, however, is unknown. The lacustrine El Molino formation of the late Cretaceous-early Paleogene Potosí Basin in present-day Bolivia contains carbonate-mud parasequences that record fluctuating hydrological conditions from 73 to 63 Ma. This study presents the first cyclostratigraphic analysis using high-resolution drone-derived imagery and 3D elevation models, combined with conventional stratigraphic measurements and magnetic susceptibility data. The drone-derived data are integrated over the entire outcrop at two field areas using a novel application of stratigraphic potential field modeling that increases signal-to-noise ratios prior to spectral analysis. We demonstrate that these parasequences exhibit significant periodicities consistent with eccentricity (400 and 100 kyr), obliquity (50 kyr, 40 kyr, and 29 kyr), precession (17-23 kyr), and semi-precession (9-11 kyr). New U-Pb ID-TIMS zircon ages from intercalacted ash beds corroborate the interpreted sedimentation rates at two sites, indicating that the Potosí Basin contains evidence for hot-house astronomical forcing of sub-tropical lacustrine hydrology. Global climate simulations of late Cretaceous orbital end-member configurations demonstrate precessional-eccentricity and obliquity driven modulation of basin hydrology. In model simulations, the forcings drive long-term shifts in the location of the intertropical convergence zone, changing precipitation along the northern extent of the Potosí Basin's catchment area. This study is the first to demonstrate orbital forcing of a lacustrine system during the Maastrichtian and could ultimately contribute to a precise age for the Cretaceous-Paleogene boundary.

    Epilepsy is one of the most common neurological diseases in Latin American Countries (LAC) and epilepsy associated with convulsive seizures is the most frequent type. Therefore, the detection of convulsive seizures is a priority, but a validated Spanish-language screening tool to detect convulsive seizures is not available. We performed a field validation to evaluate the accuracy of a Spanish-language questionnaire to detect convulsive seizures in rural Bolivia using a three-stage design. The questionnaire was also administered face-to-face, using a two-stage design, to evaluate the difference in accuracy. The study was carried out in the rural communities of the Gran Chaco region. The questionnaire consists of a single screening question directed toward the householders and a confirmatory section administered face-to-face to the index case. Positive subjects underwent a neurological examination to detect false positive and true positive subjects. To estimate the proportion of false negative, a random sample of about 20% of the screened negative underwent a neurological evaluation. 792 householders have been interviewed representing a population of 3,562 subjects (52.2% men; mean age 24.5 ± 19.7 years). We found a sensitivity of 76.3% (95% CI 59.8-88.6) with a specificity of 99.6% (95% CI 99.4-99.8). The two-stage design showed only a slightly higher sensitivity respect to the three-stage design. Our screening tool shows a good accuracy and can be easily used by trained health workers to quickly screen the population of the rural communities of LAC through the householders using a three-stage design.

    Trypanosoma cruzi, the causative agent of Chagas disease, is subdivided into six discrete typing units (DTUs; TcI–TcVI) of which TcI is ubiquitous and genetically highly variable. While clonality is the dominant mode of propagation, recombinant events play a significant evolutive role. Recently, foci of wild Triatoma infestans have been described in Bolivia, mainly infected by TcI. Hence, for the first time, we evaluated the level of genetic exchange within TcI natural potentially panmictic populations (single DTU, host, area and sampling time). Seventy-nine TcI stocks from wild T. infestans, belonging to six populations were characterized at eight microsatellite loci. For each population, Hardy-Weinberg equilibrium (HWE), linkage disequilibrium (LD), and presence of repeated multilocus genotypes (MLG) were analyzed by using a total of seven statistics, to test the null hypothesis of panmixia (H0). For three populations, none of the seven statistics allowed to rejecting H0; for another one the low size did not allow us to conclude, and for the two others the tests have given contradictory results. Interestingly, apparent panmixia was only observed in very restricted areas, and was not observed when grouping populations distant of only two kilometers or more. Nevertheless it is worth stressing that for the statistic tests of "HWE", in order to minimize the type I error (i. e. incorrect rejection of a true H0), we used the Bonferroni correction (BC) known to considerably increase the type II error ( i. e. failure to reject a false H0). For the other tests (LD and MLG), we did not use BC and the risk of type II error in these cases was acceptable. Thus, these results should be considered as a good indicator of the existence of panmixia in wild environment but this must be confirmed on larger samples to reduce the risk of type II error.

    This paper argues that migration is better defined as an adaptive response to socio-economic, cultural, political and environmental transformations, in most instances closely linked to the need to diversify income sources and reduce dependency on natural resources. Drawing on case studies in Bolivia, Senegal and Tanzania, it describes how environmental change at the local level interacts with other factors to shape migration patterns, and how such patterns in turn affect the livelihoods and resilience of individuals, households and communities in areas experiencing the impacts of climate change in the form of desertification, soil degradation, disrupted rainfall patterns and changes in temperature.

    The Bolivia-Brazil Natural Gas Pipeline - GASBOL - begins in the city of Santa Cruz of La Sierra, in Bolivia, arriving in Canoas (RS), in Brazil, traveling an extension of 3.150 Km. Of this total, 2.593 Km are in Brazilian soil. In the kilometer 526+500m of the south spread, GASBOL crosses the reservoir of the Vocoroca's dam (COPEL), which had its operational level reduced, in face of the station of the droughts that usually reaches the area in the months of March to September. The lowing of the reservoir caused the turn of the course of Fojo River (Sao Joaozinho River) to its natural quota, forming a waterfall, whose hydraulic gradient caused the removal of the sediment and part of the foundation soil, discovering the pipe that was with space free from approximately 13 m of length. This paper discusses the solution adopted, as well as the several details of the recovery project, besides geotechnical and hydraulic studies and the aspects of safety of the Gas Pipeline. (author)

    There are hardly any data available on the relationships between the parasite and the vector or regarding potential reservoirs involved in the natural transmission cycle of Trypanosoma cruzi in the Tropics of Cochabamba, Bolivia. Local families from communities were responsible for the capture of triatomine specimens, following a strategic methodology based on entomological surveillance with community participation developed by the National Chagas Programme of the Ministry of Health of Bolivia. We describe the collection of adult Panstrongylus geniculatus and Rhodnius robustus naturally infected with Trypanosoma cruzi from houses and from the hospital of Villa Tunari municipality. The flagellates found in the digestive tract of P. geniculatus belong to genetic lineages or DTUs TcI and TcIII, whereas only lineage DTU TcI was found in R. robustus. The detection of these vectors infected with T. cruzi reveals the vulnerability of local communities. The results presented here highlight the risk of Chagas disease transmission in a region previously thought not to be endemic, indicating that the Tropics of Cochabamba should be placed under permanent entomological and epidemiological surveillance.

    The Bacillus cereus group sensu lato includes six closely-related bacterial species: Bacillus cereus, Bacillus anthracis, Bacillus thuringiensis, Bacillus mycoides, Bacillus pseudomycoides and Bacillus weihenstephanensis. B. thuringiensis is distinguished from the other species mainly by the appearance of an inclusion body upon sporulation. B. weihenstephanensis is distinguished based on its psychrotolerance and the presence of specific signature sequences in the 16S rRNA gene and cspA genes. A total of seven housekeeping genes (glpF, gmK, ilvD, pta, purH, pycA and tpi) from different B. thuringiensis serovars and B. weihenstephanensis strains were amplified and their nucleotide sequences determined. A maximum likelihood phylogenetic tree was inferred from comparisons of the concatenated sequences. B. thuringiensis serovars navarrensis, bolivia and vazensis clustered not with the other B. thuringiensis serovars but rather with the B. weihenstephanensis strains, indicative of a common phylogeny. In addition, specific signature sequences and single nucleotide polymorphisms common to B. thuringiensis serovars navarrensis, bolivia and vazensis and the B. weihenstephanensis strains, and absent in the other B. thuringiensis serovars, were identified.

    2013-01-01

    Control of natural resources, especially oil and gas, has been a major issue in the consideration of underdevelopment. In the present commodity boom, some Latin American economies are reforming their resource exploitation regimes, especially those issues linked with foreign capital share. The purpose of this report is to analyze these changes in the Bolivian and Brazilian oil and gas sectors in order to answer such questions as: Which property system combining public and private capital is the most suitable? Which regulating framework can guarantee a sustainable increase in output and investment? Our analyses lead to the conclusion that the regulatory framework can establish a particular ownership structure that is considered favorable for improving the performance of oil and gas sector, but the internal dynamics and the historical trajectories of enterprises will also be determining factors that interact with the given regulatory framework, generating mixed results. - highlights: • We analyze the influence of the regulatory framework in the growth of production. • We analyze the influence of the regulatory framework in investment dynamics. • We compare the regulatory frameworks for Brazil and Bolivia. • We compare the importance of public and private companies in hydrocarbons in Brazil and Bolivia

    Full Text Available (1 The high-altitude (4,500+ m Andean mountain range of north-western Bolivia contains many peatlands. Despite heavy grazing pressure and potential damage from climate change, little is known about these peatlands. Our objective was to quantify carbon pools, basal ages and long-term peat accumulation rates in peatlands in two areas of the arid puna ecoregion of Bolivia: near the village of Manasaya in the Sajama National Park (Cordillera Occidentale, and in the Tuni Condoriri National Park (Cordillera Real. (2 We cored to 5 m depth in the Manasaya peatland, whose age at 5 m was ca. 3,675 yr. BP with a LARCA of 47 g m-2 yr-1. However, probing indicated that the maximum depth was 7–10 m with a total estimated (by extrapolation carbon stock of 1,040 Mg ha-1. The Tuni peat body was 5.5 m thick and initiated ca. 2,560 cal. yr. BP. The peatland carbon stock was 572 Mg ha-1 with a long-term rate of carbon accumulation (LARCA of 37 g m-2 yr-1. (3 Despite the dry environment of the Bolivian puna, the region contains numerous peatlands with high carbon stocks and rapid carbon accumulation rates. These peatlands are heavily used for llama and alpaca grazing.

    Full Text Available In the course of a taxonomic revision of Pseudobombax Dugand, one of us (JGCS frequently has observed herbarium specimens of Bombacoideae that comprise a mixture of different Angiosperm families. In particular, P. heteromorphum (Kuntze A.Robyns, a frequent name in checklists of the Bolivian flora, is based on type material of Bombax heteromorphum Kuntze that is clearly a mixture of Pseudobombax flowers and Tabebuia Gomes ex DC. (Bignoniaceae leaves. We herein designate as the lectotype of B. heteromorphum the flowers of an herbarium sheet deposited in NY and as epitype a complete specimen (leaves, flowers, and fruit in HUEFS. We consider Bombax heteromorphum to be a synonym of P. longiflorum (Mart. A. Robyns, a species widespread in Neotropical seasonally dry forest of Bolivia, Brazil, Paraguay, and Peru. Furthermore, we describe a new species, P. pulchellum Carv.-Sobr., apparently endemic to seasonally dry tropical forest (SDTF in Bolivia (Chiquitano dry forest, based on specimens commonly but incorrectly identified as P. heteromorphum. We also comment on the morphology, distribution, and conservation status of this new species.

    Exclusive and extended breast feeding is responsible for much of the fertility limitation and child spacing throughout the world. In many developing countries, where breast feeding is almost universal and of long duration, postpartum amenorrhea protects women from closely spaced subsequent pregnancies. However, at the same time, increased pressures toward modernization, rapid rural-to-urban migration, frequent advertisements of powdered milk substitutes, and the increased employment of women outside of the home are adversely affecting traditional breast feeding practices. In Bolivia, almost all women breast feed their newborn infants, for periods up to 2 years. This paper reports findings which describe and compare patterns of women's differential knowledge of breast feeding and lactational amenorrhea resulting from data collection using a survey instrument and a focus group guide. The findings are part of a larger study on infant feeding and child spacing conducted in periurban communities in Bolivia. Current and historical trends with regard to paradigm and methodology in social science research are reviewed and the survey/focus group research method is described.

    This work compares the results of two epidemiologic and clinical surveys on the consequences of maternal chronic Trypanosoma cruzi infection. They were conducted in 1992-1994 and 1999-2001 in the same maternity clinic in Bolivia, a country highly endemic for infection with this parasite. In both surveys, the materno-fetal transmission of parasites occurred in 5-6% of the infected mothers. Maternal chronic T. cruzi infection had no effect on pregnancy outcome and health of newborns when there was no materno-fetal transmission of parasites. Comparisons between the older and the more recent surveys highlighted significant reductions in frequencies of symptomatic cases (from 54% to 45%), Apgar scores infected babies. Neonatal mortality related to congenital Chagas disease also decreased from 13% to 2% in the interval between both studies. These results suggest that the decrease in poverty that has occurred in Bolivia between both surveys might have contributed to reduce the morbidity and mortality, but not the transmission rate of T. cruzi congenital infection, which remains a serious public health problem in this country.

En este sentido, el departamento reprodujo y amplificó no sólo el ciclo económico del país, sino también el perfil de desarrollo humano de Bolivia: el valor de su Índice de Desarrollo Humano muestra un fuerte desfase entre un indicador económico débil e indicadores sociales básicos - en las áreas de educación y salud - con valores más elevados. Los valores del IDH, los desequilibrios entre sus distintos componentes (entradas económicas, indicadores de educación y esperanza de vida al nacer, así como las correlaciones negativas rescontradas entre indicadores de pobreza y grado de urbanización municipal, ponen en evidencia importantes asimetrías internas en el departamento y permiten avanzar algunas conclusiones respecto a la sostenibilidad del proceso de desarrollo departamental cruceño.

  5. A perspective from Bolivia on the implications of the World Report on Disability for people with communication disabilities.

    Implications of the World Report on Disability for people with communication disabilities (PWCD), as described by Wylie, McAllister, Davidson, and Marshall (2013), include a drive for better demographic information, increased campaigning, and organizational change to improve speech-language pathology services. Qualitative data collected from PWCD and their families in Bolivia provide the baseline for this response. The benefits of collecting population survey information are recognized, but data reinforce the continued need to ensure a positive impact at caseload level. In a country where rhetoric is far removed from lived experience, the starting points for change are very different from those in Minority world countries. A supply and demand model is suggested as an equitable way of balancing efforts to overcome barriers to a better service. Knowledge and information are shown to be key in catalyzing the demand side for the service, while the importance of a solid evidence base for practice would help to improve supply. Although a warning against importing dominant Minority world models of service delivery is outlined by Wylie et al., findings from Bolivia support a more hybrid and nuanced approach that takes into account complex global influences of information flows, past and present.

    Full Text Available El objetivo de este trabajo es comprender y distinguir cómo se manifiesta, la ruptura o crisis de la hegemonía de las clases dominantes, cómo se presentan los procesos y posibilidades de reconfiguración de las clases sociales y las correlaciones de las fuerzas políticas entre las élites dominantes y los sectores excluidos. Se toma como referencia los casos de Bolivia y Chile en el período comprendido entre los años 2006 y 2012 ya que permite tener como referencia los triunfos electorales de Evo Morales en Bolivia y en el caso de Chile el primer gobierno de Michelle Bachelet y el triunfo de Sebastián Piñera. Desde una perspectiva hermenéutica crítica se realiza una revisión y análisis interpretativo de las obras de Antonio Gramsci y de otros referentes del pensamiento crítico latinoamericano que nos aporta un marco teórico que ilumina el análisis interpretativo. Se concluye que los conflictos y las contradicciones presentes en estos países dan cuenta de la posibilidad de construcción de nuevas relaciones sociales y políticas a partir de las luchas contra hegemónicas que han venido protagonizando las clases excluidas.

    The anthropometric status of school age children and young adolescents in Andean countries is not well known. The aim of the study was to assess the prevalence of overweight and obese children and adolescents in the Cochabamba region (Bolivia), and their association with different variables, as well as to determine the agreement between two classifications (BAP, IOTF) of obesity and overweight. A school-based cross-sectional survey (n=441) was carried out in 2010 in pupils, aged 5 to 16 years old, living in the Cochabamba region (Bolivia). Evaluations were based on parent-administered questionnaires and a physical examination based on anthropometric measures. Descriptive, bivariate, and concordance analyses were performed. The overall prevalence of overweight and obesity were 20.9% (CI95% 17.1-24.7) and 3.2% (CI 95% 1.6-4.8) respectively, with higher incidences in younger birth cohorts from rural areas. No differences were observed according to gender, parent's educational level, nutritional patterns, or physical activity. There was a moderate agreement globally and on overweight, and excellent on obesity. This study determined that the prevalence of overweight and obese Bolivian school children is increasing, mainly in younger birth cohorts from rural areas, independently from physical activity and energy intake.

    An overwhelming number of applications depend on reliable precipitation estimations. However, over complex terrain in regions such as the Andes or the southwestern Amazon, the spatial coverage of rain gauges is scarce. Two reanalysis datasets, a satellite algorithm and a scheme that combines surface observations with satellite estimations were selected for studying rainfall in the following areas of Bolivia: the central Andes, Altiplano, southwestern Amazonia, and Chaco. These Bolivian regions can be divided into three main basins: the Altiplano, La Plata, and Amazon. The selected reanalyses were the Modern-Era Retrospective Analysis for Research and Applications, which has a horizontal resolution ( 50 km) conducive for studying rainfall in relatively small precipitation systems, and the Climate Forecast System Reanalysis and Reforecast, which features an improved horizontal resolution ( 38 km). The third dataset was the seventh version of the Tropical Rainfall Measurement Mission 3B42 algorithm, which is conducive for studying rainfall at an 25 km horizontal resolution. The fourth dataset utilizes a new technique known as the Combined Scheme, which successfully removes satellite bias. All four of these datasets were aggregated to a coarser resolution. Additionally, the daily totals were calculated to match the cumulative daily values of the ground observations. This research aimed to describe and compare precipitations in the two reanalysis datasets, the satellite-algorithm dataset, and the Combined Scheme with ground observations. Two seasons were selected for studying the precipitation estimates: the rainy season (December-February) and the dry season (June-August). The average, bias, standard deviation, correlation coefficient, and root mean square error were calculated. Moreover, a contingency table was generated to calculate the accuracy, bias frequency, probability of detection, false alarm ratio, and equitable threat score. All four datasets correctly

    Diarrhoea is the second leading cause of childhood mortality, with an estimated 1.3 million deaths per year. Promotion of Solar Water Disinfection (SODIS) has been suggested as a strategy for reducing the global burden of diarrhoea by improving the microbiological quality of drinking water. Despite increasing support for the large-scale dissemination of SODIS, there are few reports describing the effectiveness of its implementation. It is, therefore, important to identify and understand the mechanisms that lead to adoption and regular use of SODIS. We investigated the behaviours associated with SODIS adoption among households assigned to receive SODIS promotion during a cluster-randomized trial in rural Bolivia. Distinct groups of SODIS-users were identified on the basis of six compliance indicators using principal components and cluster analysis. The probability of adopting SODIS as a function of campaign exposure and household characteristics was evaluated using ordinal logistic regression models. Standardised, community-level SODIS-implementation in a rural Bolivian setting was associated with a median SODIS use of 32% (IQR: 17-50). Households that were more likely to use SODIS were those that participated more frequently in SODIS promotional events (OR=1.07, 95%CI: 1.01-1.13), included women (OR=1.18, 95%CI: 1.07-1.30), owned latrines (OR=3.38, 95%CI: 1.07-10.70), and had severely wasted children living in the home (OR=2.17, 95%CI: 1.34-3.49). Most of the observed household characteristics showed limited potential to predict compliance with a comprehensive, year-long SODIS-promotion campaign; this finding reflects the complexity of behaviour change in the context of household water treatment. However, our findings also suggest that the motivation to adopt new water treatment habits and to acquire new knowledge about drinking water treatment is associated with prior engagements in sanitary hygiene and with the experience of contemporary family health concerns

Como experiencia piloto de reforma, el Ministerio de Salud y Previsión Social, el Gobierno Departamental y el Municipio de El Alto, suscribieron un acuerdo con una organización no gubernamental (ONG, a la cual transfirieron la gestión integral de una de las redes de servicios de salud del municipio. La transferencia se basó en un contrato de gestión con indicadores de proceso y resultados. Después de un año de funcionamiento, los resultados preliminares indican que, a través del acuerdo, se ha mejorado la calidad de la administración y de los servicios, aumentado la cobertura y fortalecido los servicios de primer nivel de la red. La ocupación de camas, generalmente muy baja en hospitales de segundo nivel (43% en el departamento de La Paz, 1999, alcanzó 84% en el hospital de la red en su segundo semestre de operación; las consultas externas en la red aumentaron en 55% (83% en el hospital y 18% en los centros del primer nivel entre el primer semestre de 1999 y el primer semestre del 2000; los partos institucionales aumentaron en 41% y el porcentaje de partos atendidos en los centros del primer nivel aumentó de 5 a 9% en el mismo período. Una reciente encuesta de satisfacción de los usuarios muestra que 87% de las personas atendidas en la red se sintieron altamente satisfechas con la atención recibida y que 75% de la población consultada recomendaría el servicio a otras personas. Estos datos no son típicos de los servicios de salud del país. Esta experiencia piloto sugiere que un cambio en la organización y administración de una red de servicios de salud con separación de funciones entre comprador y proveedor, combinado con una gerencia basada en resultados y la participación de la comunidad en el proceso, puede

    Cerro Rico de Potosi, Bolivia, is the world's largest silver deposit and has been mined since the sixteenth century for silver, and for tin and zinc during the twentieth century, together with by-product copper and lead. The deposit consists primarily of veins that cut an altered igneous body that we interpret to be a dacitic volcanic dome and its underlying tuff ring and explosion breccia. The deposit is compositionally and thermally zoned, having a core of cassiterite, wolframite, bismuthinite, and arsenopyrite surrounded by a peripheral, lower-temperature mineral assemblage consisting principally of sphalerite, galena, lead sulfosalt, and silver minerals. The low-temperature assemblage also was superim-posed on the high-temperature assemblage in response to cooling of the main hydrothermal system. Both the dacite dome and the ore fluids were derived from a larger magmatic hydrothermal source at depth. The dome was repeatedly fractured by recurrent movement on the fault system that guided its initial emplacement. The dome was extruded at 13.8 ?? 0.2 Ma (2??), based on U-Th-Pb dating of zircon. Mineralization and alteration occurred within about 0.3 my of dome emplacement, as indicated by a 40Ar/39Ar date of 13.76 ?? 0.10 Ma (1??) for sericite from the pervasive quartz-sericite-pyrite alteration associated with the main-stage, high-temperature, mineralization. The last thermal event able to reset zircon fission tracks occurred no later than 12.5 ?? 1.1 Ma (1??). as indicated by fission-tract dating. Minor sericite. and magmatic-steam alunite veins, were episodically formed around 11 Ma and between 8.3 and 5.7 Ma; the younger episodes occurring at the time of extensional fracturing at Cerro Rico and widespread volcanism in the adjacent Los Frailes volcanic field. None of these younger events appear to be signific-ant thermal/mineralizing events: the exceptionally flat thermal release pattern of 39Ar from sericite and the results of the fission-tract dating of

    Lack of data is a persistent problem in hydrology and other field work in developing countries. Low cost monitoring devices allow investigators to maximize spatial coverage on a limited budget, as well as to minimize the financial risk of loss of instruments placed in vulnerable locations. This work contributes to an ongoing project to evaluate the sustainability of discharge from springs supplying gravity-fed potable water systems in the Alto Beni region of Bolivia where land use is rapidly changing from forest to agriculture. The approach is to estimate ground water recharge as a function of land use variables using a water balance model in several representative watersheds. Monthly stream discharge is currently estimated using monthly manual measurements of water level by a local technician. Continuous water level measurements will allow an improved estimate of the cumulative discharge, and generate data on statistical distribution of daily flow that may be useful to estimate discharge in similar, ungaged watersheds. Continuous water level measurements, along with available precipitation data, will allow analysis and comparison of the response of watersheds to individual precipitation events as a function of land use variables. We assembled a low cost level logging system for stream flow monitoring that measures and records distance up to 6 m to the nearest 25 mm every ten minutes, and runs for a month on six rechargeable AA batteries. The system consists of a sonic range finder sensor (MaxSonar-EZ2, Maxbotix Inc., Baxter, MN, 30), a temperature sensor (MCP9701, Microchip Technology Inc., Chandler, AZ, 0.25), and a datalogger (Hobo U12, Onset Computer Corp., Pocasset, MA, 104) along with a weather-resistant enclosure and common items for a total cost of 230 per unit. The level loggers were attached to bridges over three subject streams. A local technician visits the sites monthly to download data, replace the rechargeable batteries, and take a manual water level

    Full Text Available INTRODUCTION: A descriptive, entomological and seroepidemiological study on Chagas disease was conducted in a place of recent occupation on the outskirts of Cochabamba, Bolivia: Avaroa/Primer de Mayo (population:3,000, where the socio-economic level is low and no control measures have been made available. METHODS: The immunofluorescent antibody test (IFAT was used for IgG and IgM anti-Trypanosoma cruzi antibodies in filter paper bloodspot eluates from 128 subjects (73 females, 55 males selected by systematic sampling. Concerning each subject age, gender, birthplace, occupation, duration of residence and building materials used in their houses were recorded. Vectors were captured both in domestic and peridomestic environments. RESULTS: Seropositive, 12.5% (16/128: females, 15.1% (11/73; males, 9.1% (5/55. Average time of residence: 6.1 years for the whole population sample and 7.4 years for the seropositive subjects. Most houses had adobe walls (76.7% , n= 30, galvanized iron rooves (86.7% and earthen floors (53.4% 80% of the walls had crevices. One hundred forty seven specimens of Triatoma infestans were captured, of which 104 (70.7% were domestic, and 1 peridomestic Triatoma sordida. Precipitin host identification: birds, 67.5%; humans, 27.8%; rodents, 11.9%; dogs, 8.7%; cats, 1.6%. House infestation and density indices were 53.3 and 493.0 respectively. We found 21 (14.3% specimens of T. infestans infected with trypanosomes, 18 (85.7% of which in domestic environments. DISCUSSION: The elements for the vector transmission of Chagas disease are present in Avaroa/Primer de Mayo and the ancient custom of keeping guinea pigs indoors adds to the risk of human infection. In neighboring Cochabamba, due to substandard quality control, contaminated blood transfusions are not infrequent, which further aggravates the spread of Chagas disease.

    Mounting evidence suggests that income inequality is associated with worse individual health. But does the visibility of inequality matter? Using data from a horticultural-foraging society of native Amazonians in Bolivia (Tsimane'), we examined whether village inequality in resources and behaviors with greater cultural visibility is more likely to bear a negative association with health than village inequality in less conspicuous resources. We draw on a nine-year annual panel (2002-2010) from 13 Tsimane' villages for our main analysis, and an additional survey to gauge the cultural visibility of resources. We measured inequality using the Gini coefficient. We tested the robustness of our results using a shorter two-year annual panel (2008-2009) in another 40 Tsimane' villages and an additional measure of inequality (coefficient of variation, CV). Behaviors with low cultural visibility (e.g., household farm area planted with staples) were less likely to be associated with individual health, compared to more conspicuous behaviors (e.g., expenditures in durable goods, consumption of domesticated animals). We find some evidence that property rights and access to resources matter, with inequality of privately-owned resources showing a larger effect on health. More inequality was associated with improved perceived health - maybe due to improved health prospects from increasing wealth - and worse anthropometric indicators. For example, a unit increase in the Gini coefficient of expenditures in durable goods was associated with 0.24 fewer episodes of stress and a six percentage-point lower probability of reporting illness. A one-point increase in the CV of village inequality in meat consumption was associated with a 4 and 3 percentage-point lower probability of reporting illness and being in bed due to illness, and a 0.05 SD decrease in age-sex standardized arm-muscle area. In small-scale, rural societies at the periphery of market economies, nominal economic inequality in

    Background: Mobile health (m-health) work in low- and middle-income countries (LMICs) mainly consists of small pilot programs with an unclear path to scaling and dissemination. We describe the deployment and testing of an m-health platform for non-communicable disease (NCD) self-management support in Bolivia. Methods: Three hundred sixty-four primary care patients in La Paz with diabetes or hypertension completed surveys about their use of mobile phones, health and access to care. One hundred sixty-five of those patients then participated in a 12-week demonstration of automated telephone monitoring and self-management support. Weekly interactive voice response (IVR) calls were made from a platform established at a university in La Paz, under the direction of the regional health ministry. Results: Thirty-seven percent of survey respondents spoke indigenous languages at home and 38% had six or fewer years of education. Eighty-two percent had a mobile phone, 45% used text messaging with a standard phone, and 9% had a smartphone. Smartphones were least common among patients who were older, spoke indigenous languages, or had less education. IVR program participants completed 1007 self-management support calls with an overall response rate of 51%. IVR call completion was lower among older adults, but was not related to patients’ ethnicity, health status, or healthcare access. IVR health and self-care reports were consistent with information reported during in-person baseline interviews. Patients’ likelihood of reporting excellent, very good, or good health (versus fair or poor health) via IVR increased during program participation and was associated with better medication adherence. Patients completing follow-up interviews were satisfied with the program, with 19/20 (95%) reporting that they would recommend it to a friend. Conclusion: By collaborating with LMICs, m-health programs can be transferred from higher-resource centers to LMICs and implemented in ways that

    Full Text Available The dominant paradigm in rural water provision in Bolivia has focused on the provision of infrastructure, whether by government agencies or international cooperation groups. However, the investment in infrastructure has led neither to universal access for all Bolivians nor to consistently high levels of services for those who do have access to a water system. This paper will describe the transition of one international non-profit organisation, Water For People, from supporting dispersed water projects throughout the country towards targeted support of water services at the municipal level, aiming to support permanent universal services. The institutional evolution – including changes in governance, implementation strategy, donor base, and indicators of success – that allowed field programmes to shift from projects to services provides the context for the change of approach in Bolivia. A discussion of the various aspects that have changed in the organisation’s operations in seven municipalities in Bolivia, from the scale of intervention, to municipal-wide planning information and tools, to support to service providers and service authorities, and an increased focus on post-construction monitoring, demonstrates how the Everyone, Forever approach is resulting in a more service- delivery-oriented approach in Bolivia.

    The persistence of Triatoma infestans and the continuous transmission of Trypanosoma cruzi in the Inter-Andean Valleys and in the Gran Chaco of Bolivia are of great significance. Coincidentally, it is in these regions the reach of the vector control strategies is limited, and reports of T. infestans resistance to insecticides, including in wild populations, have been issued. This study aims to characterize the susceptibility to deltamethrin of wild and domestic populations of T. infestans from Bolivia, in order to better understand the extent of this relevant problem. Susceptibility to deltamethrin was assessed in nine, wild and domestic, populations of T. infestans from the Gran Chaco and the Inter-Andean Valleys of Bolivia. Serial dilutions of deltamethrin in acetone (0.2 μL) were topically applied in first instar nymphs (F1, five days old, fasting, weight 1.2 ± 0.2 mg). Dose response results were analyzed with PROBIT version 2, determining the lethal doses, slope and resistance ratios (RR). Qualitative tests were also performed. Three wild T. infestans dark morph samples of Chaco from the Santa Cruz Department were susceptible to deltamethrin with RR50 of Bolivia are less susceptible.

    Enterotoxigenic Escherichia coli (ETEC) is a major cause of traveller's and infantile diarrhoea in the developing world. ETEC produces two toxins, a heat-stable toxin (known as ST) and a heat-labile toxin (LT) and colonization factors that help the bacteria to attach to epithelial cells. In this study, we characterized a subset of ETEC clinical isolates recovered from Bolivian children under 5 years of age using a combination of multilocus sequence typing (MLST) analysis, virulence typing, serotyping and antimicrobial resistance test patterns in order to determine the genetic background of ETEC strains circulating in Bolivia. We found that strains expressing the heat-labile (LT) enterotoxin and colonization factor CS17 were common and belonged to several MLST sequence types but mainly to sequence type-423 and sequence type-443 (Achtman scheme). To further study the LT/CS17 strains we analysed the nucleotide sequence of the CS17 operon and compared the structure to LT/CS17 ETEC isolates from Bangladesh. Sequence analysis confirmed that all sequence type-423 strains from Bolivia had a single nucleotide polymorphism; SNP(bol) in the CS17 operon that was also found in some other MLST sequence types from Bolivia but not in strains recovered from Bangladeshi children. The dominant ETEC clone in Bolivia (sequence type-423/SNP(bol)) was found to persist over multiple years and was associated with severe diarrhoea but these strains were variable with respect to antimicrobial resistance patterns. The results showed that although the LT/CS17 phenotype is common among ETEC strains in Bolivia, multiple clones, as determined by unique MLST sequence types, populate this phenotype. Our data also appear to suggest that acquisition and loss of antimicrobial resistance in LT-expressing CS17 ETEC clones is more dynamic than acquisition or loss of virulence factors.

    Triatoma infestans is the main vector of Trypanosoma cruzi in Bolivia. The species is present both in domestic and peridomestic structures of rural areas, and in wild ecotopes of the Andean valleys and the Great Chaco. The identification of areas persistently showing low and high house infestation by the vector is important for the management of vector control programs. This study aimed at analyzing the temporal and spatial distribution of house infestation by T. infestans in the Toro Toro municipality (Potosi, Bolivia) between 2009 and 2014, and its association with environmental variables. House infestation and T. infestans density were calculated from entomological surveys of houses in the study area, using a fixed-time effort sampling technique. The spatial heterogeneity of house infestation was evaluated using the SatScan statistic. Association between house infestation with Bioclim variables (Worldclim database) and altitude was analyzed using a generalized linear model (GLM) with a logit link. Model selection was based on the Akaike information criteria after eliminating collinearity between variables using the variable inflation factor. The final model was used to create a probability map of house infestation for the Toro Toro municipality. A total of 73 communities and 16,489 house evaluation events were analyzed. Presence of T. infestans was recorded on 480 house evaluation events, giving an overall annual infestation of 2.9% during the studied period (range 1.5-5.4% in 2009 and 2012). Vector density remained at about 1.25 insects/ house. Infestation was highly aggregated in five clusters, including 11 communities. Relative risk of infestation within these clusters was 1.7-3.9 times the value for the regional average. Four environmental variables were identified as good descriptors of house infestation, explaining 57% of house infestation variability. The model allowed the estimation of a house infestation surface for the Toro Toro municipality. This

    Traditional knowledge (TK) has enabled communities to adapt to changes in life conditions over centuries. However, this local context is being dramatically affected by recent changes through globalization and modernization of societies. In this paper we seek to identify socio-economic factors that are related to the knowledge and use of two palm species in mestizo and indigenous communities in the Amazonian of Peru and Bolivia. Both species are known in the region under the main vernacular name of Asaí, and are source of two highly commercialized resources: palm-hearts and fruits. Euterpe precatoria Mart. is native to the region whereas E. oleracea Mart. is being introduced for the use of both resources. We compare TK about the two Euterpe species in both countries in relation to 14 socioeconomic factors in seven use categories. We performed a Multivariate analysis of variance (MANOVA) to elucidate the influence of each socioeconomic factor on the overall palm knowledge or on individual use categories. In the two countries, we found that mestizos, speaking only Spanish, and migrants in the same ecoregion, knew more uses in all use categories for E. precatoria than for E. oleracea, even in use categories such as Medicinal and veterinary and Construction, for which indigenous participants had more uses in case of other species. In Peru, the use of E. precatoria was higher among participants with greater wealth, which could be related to the commercial importance that both the fruits and the palm-hearts have had in the markets of the region. In contrast, in Bolivia, although some income generation from Euterpe sp. was observed, the use of E. precatoria was much more homogeneously distributed. The use of E. oleracea in Bolivia is recent, and although its most important uses are related to the consumption of fruits and palm-hearts (Human food), it is now being slowly used for Medicinal and Construction purposes, similar to E. precatoria.

    The internal lining in gas pipelines aims the reduction of roughness and, consequently, the friction factor, therefore resulting in a reduction of pressure drop in natural gas flowing. During Bolivia-Brazil gas pipeline basic design, the cost benefit of internal coating was analyzed, in terms of friction factor reduction and distances between Compressor Stations. It was observed an increase of transport capacity and reduction of compressors' power, thus leading to its utilization. Since the pipeline is already in operation, using a SCADA system with Advanced Functions, a comparison between the current real friction factor in the pipeline with that theoretical values used during the design phase becomes possible. Through this comparison, it is possible to evaluate internal coating's efficiency, quantifying its real benefit for gas pipelines. (author)

    Full Text Available OBJECTIVES: To assess the challenges in reducing tuberculosis (TB in prisons in Bolivia, Ecuador, and Paraguay and propose ways to address them through communication interventions. METHODS: Challenges to two central goals of TB control-early diagnosis of positive cases and successful application of the directly observed treatment, short course (DOTS strategy-were examined. Data were gathered (through in-depth, structured interviews and focus groups were conducted in the prisons that housed the largest number of male inmates in each country. Interviewees and focus group participants included program directors, administrative personnel, correctional health and security staff, and incarcerated people who were or had been under treatment for TB and had participated as "peers" in health services. RESULTS: The findings showed a range of entrenched obstacles for adequate TB control. Stigmatizing attitudes and low knowledge about TB among inmates and key prison personnel discouraged people living in prisons from seeking diagnosis and treatment. Systemic problems in prison health services, along with squalid living conditions, lack of coordination between national TB programs and prison health systems, and insufficient allocation of resources to health prevented the provision of adequate TB prevention and care. CONCLUSION: In addressing the barriers to effective TB control in prison systems in Bolivia, Ecuador, and Paraguay, a participatory approach to communication is necessary.OBJETIVOS: Identificar los desafíos para reducir la tuberculosis (TB en cárceles de Bolivia, Ecuador y Paraguay y recomendar vías para solucionarlos mediante intervenciones informativas.

    Favreauite, ideally PbBiCu{sub 6}O{sub 4}(SeO{sub 3}){sub 4}.H{sub 2}O, is a new secondary selenite mineral from the El Dragon mine, Antonio Quijarro Province, Potosi Department, Bolivia. The mineral occurs in vughs in a matrix of (Co, Cu)-rich penroseite, dolomite and goethite. Associated minerals are: ahlfeldite, allophane, calcite, chalcomenite, malachite, molybdomenite and an unnamed Al selenite. Favreauite forms tiny green square tbular crystals, flattened on {001}, up to 0.1 mm on edge and 0.01 mm thick, occurring in subparallel and divergent groups. The Mohs hardness of favreauite is estimated as ∼3; it has perfect cleavage on {001}, an irregular fracture and a vitreous lustre. The calculated density based on the empirical formula is 4.851 g cm{sup -3}. Favreauite is uniaxial (-), with mean refractive index estimated as 1.854 from the Gladstone-Dale relationship. It is pleochroic in shades of green, O < E. Electron microprobe analyses gave the empirical formula Pb{sub 0.95}Ca{sub 0.17}Bi{sub 0.90}Cu{sub 5.81}Se{sub 4.10}O{sub 16}(OH) . 1H{sub 2}O, based on 18 O pfu.

Las familias de agricultores de escasos recursos particularmente, se verán afectados por las pérdidas de sus cultivos y la posible erosión de su agrobiodiversidad. Esto se agravará porque no cuentan con recursos económicos y tecnologías adecuadas para adaptarse a las consecuencias de los efectos del cambio climático. Los efectos del cambio climático manifestados como el cambio de temperatura, mayor incidencia de sequía, helada, granizo y otros fenómenos naturales, tienen un impacto directo sobre los niveles de producción y rendimiento de los cultivos. El fenómeno niño/niña agudizó por ejemplo la sequía en el oriente boliviano, causando en el presente año dramáticos cambios en la agricultura de Santa Cruz, así en la soya de 290.000 ha sembradas en el año 2015, este año bajo la siembra a 40.000 ha, con una reducción de la superficie cultivada de 276.2%; asimismo hubo efectos catastróficos a nivel de rendimiento, ya que de 2.5 t/ha producidas, bajo a 1.5 t/ha. Similar situación ocurre con el sorgo, el trigo, el maíz, el arroz, el girasol y la chía; y lo mismo está pasando con cultivos de seguridad alimentaria, como la papa, la quinua y las hortalizas en el occidente boliviano. Esto obligará a que el Estado Plurinacional de Bolivia, tenga que posiblemente pensar en importar estos productos para el consumo de la población boliviana, porque sus efectos recién se sentirán en el año 2017.

    Artisanal gold mining is the main economic activity in the Yani district, Northern Bolivia. In this area abundant orogenic gold deposits constituted by quartz veins hosted in paleozoic turbiditic series that contain either free gold or associated with pyrite. Gold is recovered in processing plants by gravimetric methods using shaking tables in several communities of this district. Previously, miners ground the mineral in ball mills together with mercury. The present study aims to evaluate the effect of mercury used in the gold recovering process to the environment and human health in the Yani district. The assessment was based on the analysis of human hair, sediments and water from the river nearby the processing plant and drinking water from the fountain that supplies these communities. 47 samples of hair from miners and other people from the Yani and Señor de Mayo communities were obtained in 2014 and 52 samples in 2015. All were analysed to evaluate the mercury exposure in these places. The results from the 2014 sampling show a wide range of Hg concentration in hair, especially in Señor de Mayo, with values up to 136 μg/g THg. However, in 2015 among the 43 residents in Señor de Mayo, 29 (67%) exhibit concentrations higher than 2 μg/g THg, with an average value of 5.36 μg/g THg. On the other hand, in Yani only 40% have concentrations above 2 μg/g THg, with an average value of 2.34 μg/g THg. The content in Hg in most of the hair samples exhibit values above the tolerable limits established by the US Environmental Protection Agency (1 μg/g Hg) and the World Health Organisation (WHO, 2 μg/g Hg). These high Hg concentrations are found not only in miners but also in the other members of the community, in spite of low fish consumption in this area. Part of the hair was analysed before and after cleaning. Usually in the second case the content of Hg is reduced, but still show high Hg levels, then probably the atmosphere is polluted with Hg and population is

    Congenital transmission of Chagas disease stand out as a major public health problem since the vector control was performed in all endemic areas and has shown its effectiveness. An epidemiological study was performed in three maternity hospitals of the city of Santa Cruz de la Sierra, Bolivia from 2006 to 2008. The serological screening for Trypanosoma cruzi infection was carried out in 15,767 pregnant women. Chagas infection was detected in 3725 women (23.6%), who gave birth to 125 newborns infected by T. cruzi at birth, representing an incidence of 790 per 100,000 births during a period of 16 months and a vertical transmission rate by 3.4%. There was a significant difference between hospitals that might be explained by socio-economic origins of mothers and diagnostic constraints. Copyright © 2012 Elsevier B.V. All rights reserved.

    This article examines the influence of emotional and instrumental support on women's immune function, a biomarker of stress, in the city of El Alto, Bolivia. It tests the prediction that instrumental support is protective of immune function for women living in this marginal environment. Qualitative and quantitative ethnographic methods were employed to assess perceived emotional and instrumental support and common sources of support; multiple linear regression analysis was used to model the relationship between social support and antibodies to the Epstein-Barr virus. These analyses provided no evidence that instrumental social support is related to women's health, but there is some evidence that emotional support from compadres helps protect immune function. © 2014 by the American Anthropological Association.

    Full Text Available Objectives. To determine incidence, mortality, and clinical status of youth with diabetes at the Centro Vivir con Diabetes, Cochabamba, Bolivia, with support from International Diabetes Federation Life for a Child Program. Methods. Incidence/mortality data analysis of all cases (<25 year (y diagnosed January 2005–February 2017 and cross-sectional data (December 2015. Results. Over 12.2 years, 144 cases with type 1 diabetes (T1D were diagnosed; 43.1% were male. Diagnosis age was 0.3–22.2 y; peak was 11-12 y. 11.1% were <5 y; 29.2%, 5–<10 y; 43.1%, 10–<15 y; 13.2%, 15–<20 y; and 3.5%, 20–<25 y. The youngest is being investigated for monogenic diabetes. Measured incidence in Cercado Province (Cochabamba Department was 2.2/100,000 children < 15 y/y, with ≈80% ascertainment, giving total incidence of 2.7/100,000 children < 15 y/y. Two had died. Crude mortality rate was 2.3/1000 patient years. Clinical data on 141 cases <35 y: mean/median HbA1c was 8.5/8.2% (69/62 mmol/mol, levels higher in adolescents. Three were on renal replacement therapy; four others had substantial renal impairment. Elevated BMI, triglycerides, and cholesterol were common: 19.1%, 18.3%, and 39.1%, respectively. Conclusions. Bolivia has low T1D incidence. Reasonable glycemic control is being achieved despite limited resources; however, some have serious complications and adverse cardiovascular risk factor profiles. Further attention is needed for complications.

    Potosí, Bolivia, is the site of centuries of historic and present-day mining of the Cerro Rico, a mountain known for its rich polymetallic deposits, and was the site of large-scale Colonial era silver refining operations. In this study, the concentrations of several metal and metalloid elements were quantified in adobe brick, dirt floor, and surface dust samples from 49 houses in Potosí. Median concentrations of total mercury (Hg), lead (Pb), and arsenic (As) were significantly greater than concentrations measured in Sucre, Bolivia, a non-mining town, and exceeded US-based soil screening levels. Adobe brick samples were further analyzed for bioaccessible concentrations of trace elements using a simulated gastric fluid (GF) extraction. Median GF extractable concentrations of Hg, As, and Pb were 0.085, 13.9, and 32.2% of the total element concentration, respectively. Total and GF extractable concentrations of Hg, As, and Pb were used to estimate exposure and potential health risks to children following incidental ingestion of adobe brick particles. Risks were assessed using a range of potential ingestion rates (50-1000mg/day). Overall, the results of the risk assessment show that the majority of households sampled contained concentrations of bioaccessible Pb and As, but not Hg, that represent a potential health risk. Even at the lowest ingestion rate considered, the majority of households exceeded the risk threshold for Pb, indicating that the concentrations of this metal are of particular concern. To our knowledge, this is the first study to quantify key trace elements in building materials in adobe brick houses and the results indicate that these houses are a potential source of exposure to metals and metalloids in South American mining communities. Additional studies are needed to fully characterize personal exposure and to understand potential adverse health outcomes within the community. Copyright © 2016 Elsevier B.V. All rights reserved.

El uso del concepto de subsidiaria extranjera en el país, más allá de la definición tradicional de sucursal extranjera, permite apreciar perspectivas diferentes a las habitualmente observadas sobre el desempeño de los bancos extranjeros en Bolivia. Adicionalmente, un análisis definido por las etapas de la evolución de la cartera, con aproximaciones a indicadores macro y micro, utilizando la información publicada por los bancos, posibilita también la observación de características sobresalientes y particulares en bancos nacionales y sucursales o subsidiarias extranjeras. El estudio llega a la conclusión de que los cambios más substanciales de la última década en el sistema bancario del país anfitrión, fueron protagonizados por las subsidiarias extranjeras, ya que sus modelos de negocio y actividades fueron más allá de la especialización en operaciones de comercio exterior o de carácter corporativo, pero también muestra cómo los cambios en las estrategias de sus casas matrices extranjeras pueden ser perniciosos para un sistema financiero de las características del boliviano.

    Ninety percent of nearly five million annual global injury deaths occur in low- and middle-income countries (LMICs), where prehospital care systems are frequently rudimentary or nonexistent. The World Health Organization considers layperson first-responders as essential for emergency medical services in low-resource settings lacking more formalized systems. This study sought to develop and implement a layperson trauma first responder course (TFRC) in Bolivia. In March and April 2013 nine sessions of the eight-hour TFRC were held in La Paz, Bolivia. The course charged a nominal fee, and was led by an American surgeon and medical student. The TFRC built upon existing models with local stakeholder input, and included both didactic and practical components. Participants completed a baseline survey, and pre and posttests. The primary outcome was test performance, with secondary outcomes including demographic sub-group test score analyses and exam question validation. Data were assessed using nonparametric and psychometric methods RESULTS: One hundred fifty-nine individuals met study inclusion criteria. Participant median age was 28 (IQR 24, 36), 49.1% were male, 59.1% worked in a medical field, most had secondary (35.2%) or university (56.0%) level educations, and 67.3% had prior first aid training. Median test scores improved after course completion (48% vs. 76%, p course completion, and acceptable overall psychometric test properties, indicate this model is valid and effective. Future aims include TFRC revision, and enrollment of more layperson first responders to increase population-level impacts. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Nutrition rehabilitation centers (NRCs) have shown mixed results in reducing morbidity and mortality among undernourished children in the developing world. Follow-up on children after leaving these programs remains undocumented. To assess the nutritional improvement of children attending the Centro de Rehabilitación Infantil Nutricional (CRIN), a residential NRC in rural Bolivia, from entrance to exit and to a household follow-up visit 1 month to 6 years later, and to identify factors associated with nutritional improvement. A retrospective analysis was conducted of clinical records collected by CRIN staff from 135 children under 3 years of age attending CRIN in rural Cochabamba, Bolivia, from 2003 to 2009, and of clinical records of household follow-up measurements on a subset of 26 children that were taken between 1 month and 6 years postexit. Nutritional status was evaluated by calculating z-scores for weight-for-height (WHZ), weight-for-age (WAZ), and height-for-age (HAZ). Children with z-scores < -2 were considered to be wasted, underweight, or stunted, respectively. The prevalence of wasting decreased significantly, while the prevalence of stunting did not change significantly between entrance and exit from the program. From entrance to exit, the mean changes in WHZ (0.79) and WAZ (1.08) were statistically significant, while the mean change in HAZ (-0.02) was not significant. Linear regression analysis suggested that nutritional status and diarrhea at entrance had the greatest effect on WHZ and HAZ changes between entrance and exit. Children maintained their nutritional gains from the program between exit and follow-up and showed statistically significant improvement in WAZ (but not HAZ). CRIN is effective at rehabilitating nutritional deficits associated with wasting, but not those associated with stunting.

  9. Using mixed methods to investigate factors influencing reporting of livestock diseases: a case study among smallholders in Bolivia.

    Livestock disease surveillance is particularly challenging in resource-scarce settings, where disease events are often unreported. Surveillance performance is determined as much by the quantifiable biological attributes of the disease, as it is by motivations and barriers perceived by livestock keepers for disease reporting. Mixed methods designs, which integrate the collection, analysis and interpretation of qualitative and quantitative data in a single study, are increasingly used across different disciplines. These designs allow for a deeper exploration of the topic under investigation, than can be achieved by either approach alone. In this study a mixed methods design was used in order to gain a greater understanding of the factors that influence reporting of livestock diseases in Bolivia. There is a need to strengthen passive surveillance in this country, among other reasons as part of an eradication programme for Foot and Mouth Disease (FMD). Findings revealed livestock keepers in the study area were extremely unlikely to report the occurrence of livestock health events to the Official Veterinary Services (OVS). Communication outside the local community occurs more often through alternative routes and this is positively correlated with disease awareness. The main barriers to disease reporting identified were a lack of institutional credibility and the conflicting priorities of the OVS and livestock keepers. As for other animal and human diseases across the developing world, passive surveillance of livestock diseases in Bolivia should be enhanced; this is urgent in view of the current FMD eradication programme. Increasing timeliness and smallholders' participation requires a detailed understanding of their likely actions and perceived barriers towards disease reporting. These insights are most likely to be developed through a holistic mixed methods approach of quantitative and qualitative analyses. Copyright © 2013 The Authors. Published by Elsevier B.V. All

    Current legislation transferred public tertiary hospitals in Bolivia from the Municipalities to the Regional Level. However, the Regional Governments are experiencing technical and financial constraints to reform infrastructure, modernize equipment and introduce reforms to allow better governance, management and sustainability of these hospitals. This articles summarizes the recent experience of the Government of Santa Cruz de la Sierra in Bolivia where five tertiary hospitals and blood bank (most of them in precarious working conditions) has been transferred in 2012 from the Municipal Government of Santa Cruz (the capital) to the Regional Government of Santa Cruz. To face the challenges, the Regional Government of Santa Cruz implement several improvements, such as contract new clinical and administrative personal, increases hospital budgetary autonomy, outsource hospitals' auxiliary services, take measures to eliminate waiting lists and make several new investments to modernize and equip the hospitals. The World Bank was contracted to evaluated the future financial sustainability of these investments and to advice the Government to propose changes to increase the hospitals' management performance. The article describes the remaining challenges in these hospitals and the proposals from the World Bank Study. In the area of quality of care, the main challenge is to improve client satisfaction and continuous outcomes monitoring and evaluation according quality standards. In the area of financing, the challenge is how to assure the sustainability of these hospitals with the current level of health financing and the insufficient financial transfers from the National Government. In the area of Governance, reforms to streamline and simplify internal processes need to be introduced in order to establish mechanisms to increase transparency and accountability, allowing the hospital to have a good administration and adequate participation of the main actors in the guidance of

    2015-12-01

    We describe the first Miocene turtle remains from Bolivia, which were collected from the late middle Miocene (13.18-13.03 Ma) of Quebrada Honda, southern Bolivia. This material includes a large scapula-acromion and fragmentary shell elements conferred to the genus Chelonoidis (Testudinidae), and a left xiphiplastron from a pleurodire or side-necked turtle, conferred to Acanthochelys (Chelidae). The occurrence of a giant tortoise and a freshwater turtle suggests that the paleoelevation of the region when the fossils were deposited was lower than has been estimated by stable isotope proxies, with a maximum elevation probably less than 1000 m. At a greater elevation, cool temperatures would have been beyond the tolerable physiological limits for these turtles and other giant ectotherm reptiles.

L’abaissement du front des neiges éternelles à 800-1 200 m dans la cordillère occidentale durant le DMG s’explique en partie par une augmentation des précipitations. Sur les flancs de la cordillère orientale, l’abaissement du front neigeux supérieur à 1 200 m est ce qui révèle le mieux le refroidissement subi par la région pendant le DMG.

    This paper aims to clarify and understand the reasons for the current economic policy and trade between Bolivia and Brazil, the latter represented by PETROBRAS, as the year 2006. Focuses on the regulatory change in Bolivia that culminated in a period of re-nationalization of its mineral wealth as opposed to international interests, including Brazilians, and agreements entered into during the opening of the market in the country. Thus, set in the Latin American actual situation, we undertake to understand the process and its consequences for Brazil, which, even with the third largest gas reserves in the region, in the short term, it follows as an importer of this feature. To have a concrete base with foundations and analyze what happens today, we must understand the political history of Bolivia and their internal changes. So we divided the work into two parts: first, we analyze the neo liberal period, and the agreements signed with Brazil in the hydrocarbon sector, for mutual benefits. In the second part, we understand the political rise of Evo Morales and the nationalization process of national wealth and the consequent crisis that developed with the international oil companies, especially with PETROBRAS, to the final outcome on the price, production and export of gas.

    Child health is significantly poorer in homes with intimate partner violence (IPV). However, a possible link to parental provision of childcare has been neglected. Utilizing data from Demographic and Health Surveys, this study examined the association between IPV and illness signs in children 0-59 months in Bolivia (n = 3586), Colombia (n = 9955) and Peru (n = 6260), taking into account socio-demographic factors, childcare and severe child physical punishment. Data were collected in the years 2008, 2010 and 2012 for Bolivia, Colombia and Peru respectively. The study found weak but persistent effects of IPV on illness signs in Bolivia (OR 1.37, 95% CI 1.14-1.63) and Peru (OR 1.49, 95% CI 1.26-1.77), after adjusting for the effects of childcare. These effects were not observed in Colombia. The results call for a mix of qualitative and quantitative research that can map direct, mediating and moderating patterns of relationships between IPV, childcare practices and child health. Can good childcare mitigate the negative effects of IPV? Can poor childcare exacerbate the negative effects of IPV? Such interactions were not observed in the present study, but should be the focus of much more intensive investigation, to help inform child health promotion. Answers could lead to better interventions to improve child health, and perhaps to tackle IPV.
